Ten years ago, Donald Sawdouil, a professor of materials chemistry at the Massachusetts Institute of Technology, invented high-capacity liquid metal batteries with his students. His team has now discovered the new chemical ingredient, calcium, which makes the technology cheaper and more usable, opening the way for large-scale applications of liquid metal cells.
Their latest research, published in the journal Nature Communications, shows that calcium, a rich and inexpensive chemical, can be an important starting point for three-layer liquid metal cells.
Multi-dimensional representation, this discovery is unexpected, because the properties of calcium make it seem almost impossible to become a liquid metal battery raw materials. On the one hand, calcium dissolves easily in salt solutions. However, one of the main features of liquid metal cells is that three of its key components form separate layers; on the other hand, calcium has a high melting point and, if it is used Raw materials, liquid metal batteries have to work at 900 degrees Celsius temperature.
However, this seemingly the most playful material has aroused the interest of researchers. Because cheap calcium can greatly reduce the cost of liquid metal batteries, and its inherent high pressure performance makes it a good "candidate" for liquid metal battery negative electrode layers.
To solve the problem of calcium melting point, researchers have alloyed calcium with magnesium, which is inexpensive and has a melting point well below calcium. The combination of the two reduces the original melting point by 300 degrees Celsius while still maintaining the high pressure performance of calcium.
Another innovation is in the liquid metal battery that is the middle layer of the electrolyte design. When the battery is in use, the ions move through the electrolyte, and as they move, the current passes through the wires that connect the poles of the liquid metal cell.
The newly designed electrolyte contains a mixture of lithium chloride and calcium chloride, and the calcium-magnesium alloy as the negative electrode layer is hardly dissolved in this electrolyte. This design also brings a new surprise. In general, in powered batteries, swimming ion is acting alone. For example, in lithium-ion batteries, only lithium ions swim, and only sodium ions swim in sodium-sulfur batteries. But researchers found that in the latest design, many kinds of ions move in the electrolyte, increasing the overall energy output of the battery.
Sadow said that this fortuitous discovery will open a new path for battery design. "As time goes on, you can explore more elements of the chemical's periodic table to find better battery formulations," he said.


Chances are, you’ve heard of studies dealing with the effects of blue light on human eyes. You likely know blue light is often emitted by digital devices—you’re familiar with blue light sources in Cape Cod like computers, smart phones and tablets—but what exactly is blue light and how is it produced?
Blue light is just one of many colors located in the visible light spectrum the human eye can decipher. All light features electromagnetic particles that travel in waves. Those waves carry a certain energy, and range in length and strength. Shorter wavelengths have higher energy, and longer wavelengths have lower energy, with the lengths being measured in nanometers (billionths of a meter).
There are several main categories of waves: ultraviolet (UV), gamma rays, x-rays, visible light, infrared light and radio waves. The human eye is only sensitive to visible light, the portion of the electromagnetic spectrum that shows up as colors. Think of the colors of the rainbow—red, orange, yellow, green, blue, indigo and violet. Long-term exposure to the bluer end of the spectrum, which has shorter wavelengths, could result in some long-term damage to the eyes.
Where blue light is located
Blue light exists all around you. The sun produces a broad spectrum of light, which includes light from the blue end of the spectrum. But in general, when we talk about blue light, we’re most likely to be referring to light that emanates from digital sources, including televisions, computers, laptops, tablets and smart phones, as well as light that comes from fluorescent devices and LEDs.
Blue light has shorter, higher energy waves. When they meet air molecules, they scatter around the atmosphere. This is what results in the sky appearing blue—those blue light waves interacting with the earth’s atmosphere. The body uses blue light to regulate sleeping and waking cycles, which is why you feel more alert in the presence of blue light, and why your reaction times might feel stronger. It’s also partly why you are more likely to feel happy and energized on days when the sun is shining.
However, the more exposure you have to blue light, the more your body’s circadian rhythm is likely to be affected. Constant exposure to the flickering of blue light on electronic devices can result in headaches, eye strain and fatigue. It can inhibit your ability to get a good night’s sleep. This is because the natural filters in your eyes do not provide enough constant protection against major blue light exposure. You could experience some retinal damage, as well as increase your likelihood of cataracts or macular degeneration.
Fortunately, there are some steps you can take to limit these effects. You can take breaks from screens, even if you’re required to use screens for work. Even just looking away for a few minutes each hour can be very beneficial. You can also wear contact lenses that help block out blue light effects. The technology of these lenses is constantly improving.

SpaceX or the Space Exploration Technologies Corporation, is located in Hawthorne, California. It was founded in 2002 by Elon Musk, who played a major role in the success of PayPal back in 2000 and he is part of the reason it went public in 2002. More recently, Musk is CEO of Tesla Motors, one of the leading electric vehicle manufacturers. SpaceX has since become the first companies ever to create reusable rockets and plan to make an even bigger impact in space technology in the near future.
In The Beginning
The main goal behind SpaceX when it was founded was to build an inexpensive, simple, reusable rocket that would be able to make the trip into space multiple times, with a quick turnaround time. Within only a few years, Musk had personally invested $100 million dollars into the company and by 2012 he alone held owned 70 million shares within it. He has stated that before SpaceX becomes a publicly traded company the Mars Colonial Transporter (MCT) would be flying regularly.
The MCT is a project to build and design a spaceflight system that includes reusable rocket engines, launch vehicles, and space capsules. These items will possibly transport humans to Mars and back. Each day, we come closer and closer to seeing SpaceX pull it off, but it will still take us several more years. In 2011, Musk stated that he hoped it would happen within the next 10-20 years.
Things Are Progressing Toward the Future
SpaceX has already created the Falcon 1 and the Falcon 9, both of which are launch vehicles. They were designed from the start to eventually become reusable. The Falcon 1 is a two stage to orbit rocket that uses LOX/RP-1 for both individual stages of the launch. It is powered at the first stage by a single Merlin engine. The second stage is powered by a single Kestrel engine. The Falcon 1 is the first successfully designed and built liquid propelled orbital launch vehicle that has been developed with private funding alone and it has so far made five successful launches. It did not achieve orbit until the fourth attempt which happened on September 28, 2008. It returned to orbit on July 14, 2009 and successfully delivered the Malaysian RazakSAT to orbit; its first commercial launch. It was retired at that time to be redesigned. Original plans were the Falcon 1e, but so far, the only one still active is the Falcon 9.
The Falcon 9 launches using liquid oxygen and rocket grade kerosene. This rocket is human rated to transport NASA astronauts into space so that they can reach the International Space Station. There are a few respective versions of the Falcon 9 and each of them are significant.
It is the rocket used to launch the Dragon spacecraft into orbit. The Dragon made its first flight in December 2010 after winning a Commercial Resupply Services contract from NASA in 2008. It was the first time that a commercially built and operated spacecraft to be recovered from orbit successfully. The cargo variant of it was the first of its kind to hook up to the International Space Station and it happened on the 25th of May 2012.
Where the future will take SpaceX and its Falcon launchers, no one knows yet. However, if there is a wish to get people onto Mars, we are most definitely pointed in the right direction. It should make for a very exciting future for all.


Virtually everything that happens inside our bodies depends on the action of molecular machines: proteins and other molecules whose three-dimensional structure allow them to carry out specific functions. We use cutting-edge computational approaches, together with experimental data, to understand this structure, how it changes dynamically, and how we can exploit it for a range of applications, especially the design of safer, more effective medicines. We work in close collaboration with leading academic experimentalists and with a variety of companies.
We aim not only to develop new computational methods but also to have a real impact on biology and drug discovery. Some members of the lab thus delve deeply into the study of specific biological systems. For example, we are interested in G protein-coupled receptors (GPCRs), which represent the largest class of drug targets: about a third of all drugs act by binding to these receptors and causing or preventing changes to their structure. Thanks to recent experimental breakthroughs—some of which were recognized by a Nobel Prize to Brian Kobilka, our Stanford colleague and collaborator—the structures of many GPCRs have been solved in the last few years. We use computational methods to reveal the dynamics and mechanisms of these proteins and the drugs that target them.
Many of the projects currently underway in the lab involve one or more of the following approaches, but the techniques we employ are continually evolving, and we always welcome new ideas.
Molecular simulation: Molecular dynamics simulations predict the atomic-level motions of proteins using basic physical principles. They have become much more powerful in recent years, thanks to advances in computer power, algorithms, and chemical models. They can now be used to reveal the workings of processes such as drugs binding to their targets or the structural changes that underlie protein function.
Machine learning: We use modern machine learning techniques, as well as new statistical inference techniques that we develop, to infer structural models from experimental data, to analyze simulation results, and to synthesize data from different sources. For example, we predict how drugs bind to their targets or how proteins associate with one another to form larger complexes.
Analysis of image data from microscopy: Advances in cryo-electron microscopy and fluorescence microscopy are revolutionizing structural and cellular biology. These methods generate a huge amount of image data. We are developing methods that leverage this data to provide a dynamic picture of molecular and cellular machines.


ISO 10677: 2011 – Ultraviolet light source for testing semiconducting photocatalytic materials.
All the ISO tests utilised make reference to the use of a suitable UV light source. However, typically three different types are recommended – two types of BLB and a xenon arc lamp. The relative light intensity vs. wavelength profiles for (a – solid) a xenon arc lamp, (b – dashed) a BLB light source with λmax (other than peak at 365 nm) at ca. 351 nm and (c – bold) a BLB light source with λmax (other than peak at 365 nm) at ca. 368 nm are illustrated below.
The specification of a suitable UV light source is paramount to repeatability and reproducibility of the standard tests reported, and since the photocatalytic efficiency of a system depends upon the spectral distribution and radiant intensity of the light source, only one type of BLB, namely one with a europium-doped fluoroborate phosphor is used in our testing. In order to evaluate photocatalytic materials for use in sunlight however, xenon arc lamps are used.
At QIPS we can measure the emission spectrum and UV irradiance (units: mW/cm2) of your submitted light source using a calibrated spectroradiometer, and compare and contrast it to that of other light sources.
Black light fluorescent lamps are made as normal white light fluorescent tubes except that only one phosphor is used, and the glass envelope has a blue filter which ensures that most of the light emitted is UVA light. The two types of BLB arise because there are two types of phosphor, namely: (i) europium doped fluoroborate, which produces a UV emission peak ranging from 368-371 nm and a band width of 20 nm and (ii) lead-doped barium silicate with a UV emission peak ranging from 350-353 nm and a band width of 40 nm .
To produce solar simulated UV light (and ensure the significant visible component is removed) we use a UG5 filter (cuts out most light between 400-650 nm ) in combination with a WG320 filter (cuts out light below 300 nm ). The overall emission has been shown to be a very good fit to the actual solar UV emission spectrum. The removal of most of the visible light produced by the Xe arc lamp is also a very important feature, since the standards are designed for UV absorbing systems only.
We use a calibrated spectroradiometer, for measuring the UV irradiance.
The relative light intensity vs. wavelength profiles for (a – solid) a xenon arc lamp, (b – dashed) a BLB light source with λmax (other than peak at 365 nm) at ca. 351 nm and (c – bold) a BLB light source with λmax (other than peak at 365 nm) at ca. 368 nm are illustrated below.

Smart and elegant for the energy future
Innovations for the energy turn-around at the Tulln Hausbau & Energie Fair
From 22 – 24 January, the Messe Tulln trade fair is setting the tone for the topics of construction, renovation, living and energy conservation. VERBUND is presenting new products for clever energy savers who want to organise their homes more efficiently, independently, sustainably and safely, and is thus sending signals that are just as clear as they are elegant for customers and the environment.
As a supplement to the proven VERBUND eco-packages, together with SOLAVOLTA, VERBUND is now bringing the Powerwall from Tesla Energy to the Austrian market and providing private customers more storage at a better price, and all that in the stylish Tesla design.
High-power home storage
With 7 Kilowatt hours for daily-cycle operation, the Daily Cycle Powerwall provides enough capacity to sustain most private households with self-generated electricity even at times of peak expenditure. In the case of an electricity outage, it supplies the energy necessary for a half a day of normal operation or around one to one and a half days of emergency operation. A sunny afternoon provides for a fully charged store and is sufficient to supply an A+++ combined refrigerator-freezer with energy for 12 days or to run an A+ television for more than 120 hours.
Another level of personal use
The average household consumes between 10 and 15 kWh of electricity every day, particularly in the morning and the evening. However, solar energy is available primarily at midday and in the afternoon. Storing energy the right way represents the solution to this disparity. With the Powerwall from Tesla Energy, renewable energy is stored elegantly and self-generated solar electricity can be used according to need at any time of day – for private consumption is the most efficient use of self-generated electricity from a PV unit. Because its temperature fluctuation range spans from -20°C to 50°C, the device is suited for both indoor and outdoor use.
VERBUND Eco Packages for private customers
VERBUND is offering Eco-Packages especially designed for private homes: Through the combination of a photovoltaic system plus battery storage and a heat pump, even self-generated energy can be simple, efficient, and affordable to use. Customers benefit from convenient solutions and customised tariffs. At the trade fairs in spring 2016, in addition to an attractive trade fair deal for photovoltaic systems, there are also fixed-price offers featuring up to 1,100 euros in savings. New in the programme are photovoltaic packages including Eco-Home hot water heat pumps. For each photovoltaic system that is bought through VERBUND, there will be a heightened feed-in tariff.
Clever energy efficiency for the home: VERBUND Eco-Home
The Smart-Home solution offers innovative applications such as the measurement and visualisation of all relevant energy flows in the household, status updates and alarm messages on your mobile phone, as well as the ability to automatically regulate controls for consumers with self-generated solar electricity. The integration of an electricity measurement module visualises all electricity consumption and makes it possible to measure electricity feed-in in real time. Users with photovoltaic units can then turn on household appliances when enough own electricity is being produced. Energy costs go down, and comfort goes up.
VERBUND Complete Packages: easy, quick and budget-friendly
The innovative technology comes home with you as a complete package. VERBUND customers receive their own personal home of the future conveniently and safely from a single source.
As one of Europe's largest producers of electricity from hydropower, VERBUND is setting the tone for the generation of electricity from renewable sources. With the Eco-Packages for energy savers, VERBUND is taking further important steps for the energy future, connected with more independence, sustainability and security. VERBUND's pallet is rounded off with attractive offerings for electricity from 100% hydropower both for households as well as for environmentally friendly mobility, electromobility. "Electricity supply will soon be absolutely CO2-free and renewable, and with every individual PV unit, it becomes more decentralised. No matter whether it is household customers, industrial firms or commercial enterprises, the intelligent use of energy and resources is a must for everyone. VERBUND has intelligent products and solutions for exactly that. We combine ecology, economy and design," emphasises Martin Wagner, Director of VERBUND Solutions GmbH.

After many months of rumors and speculation, the first iPhone was officially announced on January 9th, 2007. Also known as the “iPhone EDGE” or “iPhone 2G”, it was launched in the United States on June 29th, 2007, before being marketed in a few other European countries as well before the end of 07.
Featuring quad-band GSM, the EDGE compatible iPhone was the first phone with an entirely software based interface, and no hardware keyboard. It was an amazing concept, named by Time magazine, the 2007 invention of the year.
The iPhone 3G is launched July 11, 2008 in the world, he admits the standard 3G via UMTS with HSDPA 3.6 Mb/s and has a GPS device. It has a plastic casing and some pretty weak specs by today’s standard.
The iPhone 3GS was introduced June 19, 2009. Identical in appearance to the 3G but sporting an integrated video camera, increased megapixels and auto-focus for its photo function, better overall performance and introduces voice commands and a compass. It supports downloading of 3G data at 7.2 Mb/s HSDPA It in the US, Canada UK, Germany, France, Austria and Ireland.
The iPhone 4 was announced at the June 7, 2010 conference by Steve Job. The release of iOS 4 coincided with the release of the new iPhone. In comparison with the 3GS, the 4 has a superior screen definition (960 ×640 px vs 480 ×320 px) and the new Retina display, integrated flash, and a front-facing camera for video conferencing.
The iPhone 4S is identical in appearance to the iPhone 4, was announced at Apple headquarters on October 4, 2011 by Tim Cook the new CEO of the firm. With a new A5 dual-core processor chip, it incorporated some major improvements over previous versions including an 8 MP camera, SIRI the personal assistant , voice recognition, and the new IOS5 operating system 5.
The iPhone 5, with the new IOS 6 with the new A6 chipset., was introduced on September 12, 2012. It features a longer screen but the same width as the previous iterations. The improved definition 1136px x 640px with an aspect ratio of 16:9. It weighs only 112 g and uses the Apple Lightning connector instead of the 30-pin connector. The back of the iPhone 5 is made of anodized .


Imagine a future where your smartphone’s microphone can be used to automatically alert medical staff that you’re having a heart attack.
That’s the level of technology envisioned for a new app being created for the Pentagon to keep track of a soldier’s health on the battlefield.
The software will harvest data from cameras, light sensors, pedometers, fingerprint sensors, and other sensors to make its evaluations.
Funded by secretive weapons development agency Darpa, the military technology is likely to become publicly available in the not too distant future.
Kryptowire, a cybersecurity firm based in Fairfax, Virginia was awarded a $5.1 million (£3.5 million) contract to create the app.
It’s part of the Defense Advanced Research Projects Agency (Darpa) funded warfighter analytics using smartphones for health programme, also known as Wash.
The app will passively collect smartphone sensor measurements to provide real-time monitoring of a soldier’s health, as well as detecting biomarkers for early disease diagnosis.
It aims to allow intervention in medical issues, before a patient has to visit a doctor or nurse due to symptoms developing.
However the privacy implications of the app, being built for Android and iOS, are of concern to experts.
Funded by secretive weapons development agency Darpa, The software will harvest data from cameras, light sensors, pedometers, fingerprint sensors, and other sensors to keep track of a soldier’s health on the battlesecretive field (stock image)
‘If you’re activating a microphone on someone’s phone, that is going to raise a lot of alarms, Jay Stanley, a senior policy analyst with the American Civil Liberties Union, told the Washington Post.
‘People don’t want to feel like someone is listening in on their private life. That’s going to have to be subject to tight controls.’
Currently, understanding and assessing the readiness of a soldier to fight involves medical intervention.
This is often with the help of advanced equipment, such as electrocardiographs (EKGs) and other specialised medical devices.
However, these are often too expensive and cumbersome to employ continuously or without supervision during active service.
On the other hand, 92 per cent of adults in the United States own a smartphone, or other mobile device.
These could be used as the basis for continuous, passive health, and readiness assessment.
Wash seeks to use data collected from smartphone sensors to enable specially created algorithms to analyse their measurements.
The objective of Wash is to extract physiological signals, which may be weak and noisy, that are embedded in the data obtained through existing mobile device sensors.


New sorting machine Planet 6G
Our latest acquisition in production is an automatic sorting machine Enclony Planet 6G. Enclony was founded in 2013 as a research and development oriented company specializing in visual analysis technology for tablet and capsule forms in the field of pharmaceutical production. In 2018, the current PLANET 6G model was developed. Enclony has its own technologies in the field of mechanics, algorithms, hardware, programs and electrical controls necessary for visual inspection. Tablets are inspected for defects using ten 2D cameras that cover the entire surface. In addition, two 3D cameras are used to analyze the height as well as engraving of the tablets. When inspecting capsules, an infrared camera is used instead of the two 3D cameras to check the capsules for their fill quantity. All tablet shapes (oblong, round, etc.) as well as capsule sizes can be inspected for defects. These include chipping, stains, dots, color deviations, foreign bodies, dents, and missing or incorrect engravings/labeling. Depending on the size of the product being inspected, between 120,000 - 350,000 tablets/h or 90,000 - 150,000 capsules/h can be inspected.


Our research program is focused on deep brain stimulation (DBS) and the design of novel techniques to improve its clinical application. Our primary research methods rely on coupling computational modeling with experimental measurement in human subjects implanted with neuromodulation technology. We pioneered the concept of patient-specific DBS modeling and made our most important scientific contributions by blending finite element electric field models of DBS with high resolution MRI data. This led to the creation of academic software technologies for modeling the effects of DBS on individual patients, which are now commonly available commercial clinical tools. Our current research efforts focus on evolving that translational pipeline with the integration of biophysical details on the neural response to DBS with anatomically accurate representations of the axonal connections in the human brain (i.e. “Connectomic DBS”). In addition to electrical stimulation modeling, the laboratory also maintains an active research effort studying the biophysics of neural signals recorded by electrodes implanted in the brain.


Nickel-based alloys find applications in various components such as RTD sensors, resistors, rheostats, voltage control relays, heating elements, potentiometers, and others. Engineers tailor their designs to leverage the unique properties exhibited by each specific alloy.
Nickel is widely chosen for wire applications due to its exceptional resistance to severe chemical corrosion, including oxidation in air and water. Nickel alloys also demonstrate remarkable resilience against acids and alkalis. Consequently, nickel wire is extensively utilized in products that incorporate electrical components or operate under high-temperature conditions (up to 2,600 °F). Moreover, nickel retains its magnetic properties as long as its temperature remains below 350 °F. Beyond this threshold, the wire loses its magnetic characteristics.
The distinctive traits of nickel alloys often surpass the usefulness of other metals like brass, copper, and beryllium, particularly when deployed in outdoor wire applications. Nickel wire exhibits exceptional corrosion resistance, even at extremely high levels. It withstands oxidation caused by air and water, as well as contact with acids and alkalis. The protective layer on the surface of nickel, known as passivation, shields the compound from chemical reactions. Nickel is considered a non-reactive metal that dissolves slowly in acids.
Another significant advantage of nickel wire is its resistance to melting. Unlike many other metal alloys, nickel possesses a high melting point, enabling it to endure temperatures up to 2,600 degrees Fahrenheit (1,203 Celsius). Additionally, nickel wire exhibits robust strength and durability, enabling it to withstand significant wear and tear. It also offers ease of stretching.
While nickel wire possesses strong magnetic properties, these characteristics are only present when the wire is not subjected to high temperatures. Once heated to approximately 350 degrees Fahrenheit, nickel wire loses its magnetic abilities.

Deep learning (DL) models have been shown to outperform conventional machine learning techniques in a variety of research fields and prediction tasks. Yet, their application to the decoding of functional Magnetic Resonance Imaging (fMRI) data has so far been limited. Mainly, because DL models are often viewed as "black boxes", disguising the relationship between input data and prediction due to their highly non-linear nature. It is, however, a central goal of cognitive neuroscience to identify (and learn about) the association between brain activity and the underlying cognitive state of an individual (e.g., while viewing images of different categories or performing a specific cognitive task).
The lack of understanding and interpretation of the decision process of deep learning models is a clear drawback and has recently also attracted attention in the field of machine learning (see for example, this overview). In this context, the so called Layer-wise Relevance Propagation (LRP) technique has been proposed as a general technique for explaining the predictions of predictive functions. Specifically, the LRP technique decomposes the predictions of a decision model into the contributions (or relevances) of the features of the input data to the predictions.
In the DeepLight framework, we utilize the LRP technique to interpret the decoding decisions of a deep learning model that is trained to identify (ie., decode) a set of cognitive states from whole-brain fMRI data, thereby, relating the brain activity to the decoded cognitive state:
The DL model that we used in this study consists of three distinct computational modules: a convolutional feature extractor, an LSTM, and an output unit. First, the DL model separates each fMRI volume into a sequence of axial brain slices. These slices are then processed by a two-dimensional convolutional feature extractor, resulting in a sequence of higher-level, and lower-dimensional, slice representations. These higher-level slice representations are then fed to an LSTM, integrating the spatial dependencies of the observed brain activity within and across axial brain slices. Lastly, the output unit makes a decoding decision, by projecting the output of the LSTM into a lower-dimensional space, spanning the cognitive states in the data. Here, a probability for each cognitive state is estimated, indicating whether the input fMRI volume belongs to each of these states. Subsequently, DeepLight relates the brain activity and cognitive state, by applying the LRP technique to its decoding decision. Thereby, decomposing the decision into the contributions of the single input voxels to each decision. Importantly, the DeepLight approach is not dependent on any specific architecture of the DL model. The DL model architecture described here is exemplary and derived from previous work.
Importantly, the LRP decomposition is performed on the level of a single fMRI volumes (and decoding decisions), which allows for an analysis on several levels of data granularity, from the level of the group down to the level of single subjects, trials and time points. DeepLight is thereby able to study the temporal and spatial distribution of brain activity across sequences of single fMRI volumes.
The following two videos exemplify this feature, by showing the distribution of relevance for each fMRI sample of a trial (25 s) in which participants either see the image of a face (video 1) or the video of a place (video 2) (for more details on this analysis, see Figure 6 of our paper):
In addition to the relevance distribution on the right, the videos show DeepLight's softmax prediction for each of the four target classes of the underlying experiment (top left panel; in the experiment, participants saw images of body parts, faces, places, and tools), DeepLight's average decoding accuracy (middle left panel), as well as a similarity measure (the F1-score; lower left panel), quantifying the similarity between the shown distribution of relevance and the distribution of brain activity that one would expect, given a meta-analysis with NeuroSynth for the terms "face" and "place" (higher F1-score values generally indicate more similarly).
Video 1 (face):
Video 2 (place):
Overall, we find that DeepLight accurately identifies the two target classes from the fMRI data, as indicated by an increasing decoding accuracy over the course of the trials. In addition, DeepLight utilises the brain activity from a set of biologically plausible brain regions to identify each of the two target stimuli (as shown by generally increasing F1-scores which describe the overlap between the relevance distributions shown on the right and the results of our meta analysis), thus indicating that DeepLight's brain maps capture a biologically plausible association between brain activity and cognitive states (here, the viewing of face and place stimuli).

The force acting on a levitating droplet/particle can be calibrated
by using gravity as in the Millikan experiment. It is convenient to
tilt the chip, i.e. to use "magnetic incline". We have used this
to achive femtonewton resolution in force. However, this resolution
can be improved by several orders of magnitude.
Consider typical, 3 micron in diameter droplet.
It has volume about 15 femtoliter and weight 150 femtonewtons.
By controlling tilt angle with resolution of 0.1 millirad, it is
feasible to calibrate force acting on the droplet with resolution
15 attonewtons. Typically droplet(s) are captured in a potential well.
Tilt means droplet shift in this well. The "force constant" in such
well in the direction parallel to the slit between the magnets
can be as small as 10 attonewton/micron. With video system
(microscope + camera) resolution of 0.1micron this provides possibility
to control force with attonewton resolution. Of course, with such
small value of force constant the amplitude of brownian motion (see next
movie) can reach 10 micron.
However, large enough statistic provides possibility
for accurate measurements (see
for more details).

Concern over the safety of radiofrequency (RF) energy from cellular telephones and transmitting facilities for cellular systems has grown alongside the potential increase in public RF exposure resulting from the proliferation of wireless communication systems. RF communication bands, which include AM/FM radio, very high frequency (VHF) and ultra-high frequency (UHF) television, cellular telephones, pagers, two-way radios, radar, and satellite communications, make up part of the nonionizing portion of the electromagnetic spectrum.
Analog cellular telephones operate in the rage of 800-960 MHz, and new digital personal communication devices operate in the rage of 1600-2000 MHz. The thermal effects of high exposures to RF electric and magnetic fields are the basis for existing safety and health exposure guidelines. The current scientific consensus is that there is insufficient evidence from animal and epidemiologic research to demonstrate adverse human health effects (Environ Health Perspect 1999 Feb;107 Suppl 1:155-68; Radiation Research 1999 May;151(5):513-31). Nevertheless, it is prudent to avoid unnecessary and prolonged exposures. One way of doing this is by using devices that allow the cell phone antenna to remain at an extended distance from the body. It should be emphasized that radiation induced malignancies take years to occur. The wide use of cellular phones remains relatively short and longer follow up is needed to make any definitive conclusions.

Cryptography Essentials for Smart Contracts 🔒🔑
Cryptography essentials, including encryption, hash functions, digital signatures, and zero-knowledge proofs, are vital for ensuring the security and integrity of smart contracts, protecting sensitive data, and establishing trust in decentralized systems. 🔒🔑
Cryptography plays a crucial role in ensuring the security and integrity of smart contracts, which are self-executing agreements built on blockchain technology. Understanding the essentials of cryptography is essential for developers and users of smart contracts to protect sensitive data, prevent unauthorized access, and establish trust in decentralized systems. In this blog post, we will explore the fundamentals of cryptography and its significance in the context of smart contracts.
Symmetric and Asymmetric Encryption:
Cryptography relies on encryption algorithms to secure data. Symmetric encryption uses a single shared key for both encryption and decryption, while asymmetric encryption involves a pair of keys: a public key for encryption and a private key for decryption. Smart contracts often utilize asymmetric encryption to ensure secure communication and data transfer between parties involved.
Hash functions are cryptographic algorithms that convert input data into a fixed-size string of characters, known as a hash. These functions are used to verify the integrity of data and ensure that it has not been tampered with. In the context of smart contracts, hash functions play a critical role in verifying the state of the contract and ensuring its immutability.
Digital signatures are used to authenticate the origin and integrity of data. They involve the use of asymmetric encryption, where the sender signs the data with their private key, and the recipient can verify the signature using the sender's public key. Smart contracts utilize digital signatures to ensure that only authorized parties can interact with the contract and to validate the authenticity of transactions.
Secure Multi-Party Computation:
Secure Multi-Party Computation (SMPC) is a cryptographic technique that allows multiple parties to jointly compute a result without revealing their individual inputs. SMPC ensures privacy and confidentiality in scenarios where sensitive data needs to be processed collectively. In the context of smart contracts, SMPC can enable secure collaborations and decision-making among multiple participants without compromising data privacy.
Zero-Knowledge Proofs (ZKPs) are cryptographic protocols that enable one party to prove the knowledge of certain information without revealing the actual data itself. ZKPs play a significant role in privacy-preserving smart contracts, where sensitive information needs to be shared selectively while maintaining confidentiality. ZKPs allow for the verification of computations without exposing the underlying data, ensuring privacy and security.
Cryptography is an indispensable component of smart contracts, ensuring the security, privacy, and integrity of data and transactions. Understanding the essentials of cryptography, including symmetric and asymmetric encryption, hash functions, digital signatures, secure multi-party computation, and zero-knowledge proofs, is crucial for developers and users of smart contracts. By leveraging these cryptographic techniques, we can build secure and trustworthy decentralized systems that enable secure transactions, protect sensitive data, and foster trust among participants. Stay informed about the latest advancements in cryptography to enhance the security and resilience of your smart contracts. 🔒🔑


Hybrid Fiber/Copper Access Networks
Hybrid fiber/copper access networks consist of both fiber and copper segments to reach network subscribers. These hybrid access networks utilize passive optical network (PON) technology on the fiber segment and either digital subscriber line (DSL) or cable modem technology on the copper segment. A PON is an economically sensitive candidate technology for bringing fiber optic transmission to individual subscribers (businesses or individuals) through the access network.
Communication networks can be partitioned into two broad categories: 1) public and 2) private. Public networks are those that are established by service provider companies (e.g., AT&T, and Qwest) for public use. Private networks are those that are established by private entities (e.g., UTEP) for use by the entity. Individuals or institutions pay one or more service providers for a connection to one or more public networks that typically offer global connectivity (i.e., the Internet).
The access network interconnects the public and private networks. The access network is actually a portion of the public network that reaches out to the individual subscriber (i.e., private) networks. At present, the access network consists primarily of copper transmission media (e.g., twisted pair [digital subscriber lines], and coaxial [cable tv]). PONs are an attractive option for converting the access network to a fiber optic transmission media because of their low cost.
We have leveraged our deep expertise of dynamic bandwidth allocation (DBA) for Ethernet Passive Optical Networks (read information on that project below) to study access networks consisting of both fiber and copper segments. In many access network deployment scenarios it is still not economically attractive for service provider companies to deploy fiber all the way to subscriber locations despite the low cost of PON deployments. In these scenarios, service provider companies will deploy a PON within 100 meters or so of subscribers and utilize existing twisted pair copper or coaxial copper to reach subscribers. The point at which the fiber segment is terminated is referred to as a "drop point". For that reason the equipment that bridges the fiber and copper segments of the network at the "drop point" is simply called a "drop point" device. The fundamental goal of our research is to study mechanisms to reduce energy consumption at the "drop-point" device.
We have pursued two strategies to reduce energy consumption at the "drop point" device. The first strategy moves some of the copper technology logic blocks (e.g., DSL logic blocks) from the drop point to the service provider companies central office (CO) where power is abundant. Less logic at the drop point translates to fewer transistors that consume power. Moving logic blocks to the CO location has performance repercussions. Our study uncovered these repercussions and mechanisms to alleviate or reduce their impact. The second strategy reduces the buffering that occurs at the drop point device. Reduced buffering means smaller memory devices with fewer transistors that consume power. Our research uncovered a few mechanisms for reducing buffering in both the downstream and upstream directions. Please read our published articles for further detail.
Ethernet Passive Optical Networks (EPONs)
Ethernet PONs (EPONs) are PONs that utilize the ubiquitous Ethernet protocol.
The fundamental goal of this research on EPONs has been to increase channel utilization. Increasing channel utilization increases the useable bandwidth on each individual PON. Increased useable bandwidth reduces the cost per unit of bandwidth. Stated more directly, the goal has been to lower the cost per unit of bandwidth on EPONs to help promote their rapid deployment.
Through analytical and behavioral modeling of EPONs, we came to understand what contributes to wasted bandwidth and have used the scheduling component of dynamic bandwidth allocation to minimize this wasted bandwidth. This research has resulted in the discovery of two transmission scheduling (i.e., grant scheduling) techniques that can significantly improve channel utilization: 1) online just-in-time scheduling, and 2) shortest propagation delay first scheduling. Dynamic Bandwidth Allocation (DBA) is the act of managing the bandwidth or information capacity of transmission channels. For EPONs, DBA can be broken into two components: 1) grant sizing, and 2) grant scheduling. Please read our published articles for further detail.
Video Bandwidth Forecasting
According to a report from Cisco Systems, video will make up 90% of consumer network traffic by 2012. Optimizing communication networks for the delivery of video information is obviously critical for these networks to meet the information transfer requirements of the future.
Digital video is compressed to reduce its bandwidth requirements so that transport over communication networks is feasible. The compression of video results in time variance of the bandwidth requirements of the video. This time variance makes allocating bandwidth in communication networks challenging. The easiest approach is to allocate for the maximum bandwidth of the video but that approach will result in significant wasted bandwidth in the network. The more efficient approach is to allocate for the mean bandwidth and use statistical multiplexing to share transmission channels among many videos. A bandwidth forecast can be used to improve the efficiency of statistical multiplexing.
The fundamental goal of our research on video bandwidth forecasting is to discover a forecast method that is accurate and simple to implement.
It turns out that most video communication involves pre-recorded video. With pre-recorded video, true bandwidth forecasts are not required since the size of all of the video frames is known prior to their delivery over a communication network. The problem therefore reduces to simply getting future video frame size information into the network. Rami Haddad and I came up with a technique we call Feed-Forward Bandwidth Indication (FFBI) that places "future" video frame size information in "past" video frame headers where network equipment can access them. This technique can also be used with live (i.e., real-time) video if we introduce a little delay at the source. Please read our published articles for further detail.


NASA recorded this over a four year time span . . .
“Outstanding Time-Lapse of a Stellar Explosion from Hubble
In January 2002, astronomers discovered a massive explosion coming from V838 Monocerotis. They initially thought they were witnessing a supernova, but after the initial flash of light began to dim (as expected), it began to brighten again in infrared wavelengths at the beginning of March. After that brightening faded, another one happened in April. While astronomers were certain they weren’t witnessing a supernova, they weren’t quite sure what it actually was.”


Cho named NASA Space Technology Research Fellow
Chullhee (Chace) Cho, a PhD candidate in MechSE, has been selected as a 2017 NASA Space Technology Research Fellow (NSTRF). Cho conducts research on two-dimensional materials in Assistant Professor SungWoo Nam’s lab.
The competitive fellowships, which sponsor U.S. citizen and permanent resident graduate students who show significant potential to contribute to NASA’s goal of creating innovative new space technologies for our Nation’s science, exploration and economic future, are made in the form of grants to U.S. universities, with the student’s faculty advisor serving as the principal investigator. The fellowship will enable Cho to collaborate with top researchers at NASA’s Langley Research Center and perform his research at various facilities.
Cho’s proposal, “Frequency Tunable Piezoelectric Energy Harvester based on Crumpled MoS2 and Graphene,” will focus on a new type of energy harvester based on crumpled structures of two-dimensional materials and ensuring mechanical flexibility, frequency-tunability, lightweight and radiation-tolerant features.
Most space missions are long-term, and some are conducted entirely remotely, making issues in power generation crucial, particularly given the constraints on sources like fuel or energy harvesting systems on spacecraft. Conventionally used batteries are bulky, pose a danger of explosion, are inconvenient to recharge, and suffer from limited lifetime. As a result, the development of lightweight energy generation devices with high power outputs and low cost is essential.
According to Cho, harvesting ambient energy is a possible solution to extend the limit of power production in space. Many researchers, including those at NASA, have been working on energy harvesters to convert vibration energy into usable electric energy based on piezoelectric materials. Cho proposes converting energy from vibration sources to electrical energy that astronauts can use in their daily activities in space.
Compared to previously fabricated nanogenerators, a single layer of an MoS2 based nanogenerator has the advantage of withstanding enormous strains, while also being lightweight and with a high stiffness and high surface area-to-volume ratio. These present some of the biggest challenges NASA faces for future space missions as well as energy problems—and if resolved, could increase the life and scope of space missions.
Space exploration missions require devices capable of stable operation in harsh environments such as damage from cosmic rays. Improving the frequency-tunability could affect power output, resulting in a better response range to the surrounding environment. Combining graphene with MoS2 can provide radiation-tolerant structure to the whole system. Harmful radiation can be mitigated by taking advantage of the inherent radiation tolerance and electrical conductivity of graphene.
Additionally, said Cho, “The dimension we are dealing with here is in the atomic scale. In other words, we can enhance the performance by stacking up the layers of device while still in nano- or micro- scales.”
Cho earned his bachelor’s and master’s degrees in 2011 and 2013. He worked as a research engineer for Korea Institute of Industrial technology until 2016, when he joined MechSE for his PhD degree.


PCB CAM Manufacturing starts from the PCB fabrication data generated by CAD: Gerber layer images, Gerber or Excellon drill files, IPC-D-356 netlist and component information. The Gerber or Excellon files in the fabrication data are never used directly on the manufacturing equipment but always read into the CAM (Computer Aided Manufacturing) software. CAM performs the following functions
- Input of the fabrication data.
- Verification of the data; optionally DFM
- Compensation for deviations in the manufacturing processes (e.g. scaling to compensate for distortions during lamination) Panelization
- Output of the digital tools (copper patterns, solder resist image, legend image, drill files, automated optical inspection data, electrical test files
The first step is to replicate the pattern in the fabricator's CAM system on a protective mask on the copper foil PCB layers. Subsequent etching removes the unwanted copper. (Alternatively, a conductive ink can be ink-jetted on a blank (non-conductive) board. This technique is also used in the manufacture of hybrid circuits.)
- Silk screen printing uses etch-resistant inks to create the protective mask.
- Photoengraving uses a photomask and developer to selectively remove a UV-sensitive photoresist coating and thus create a photoresist mask.
- Direct imaging techniques are sometimes used for high-resolution requirements. Experiments were made with thermal resist.
- PCB milling uses a two or three-axis mechanical milling system to mill away the copper foil from the substrate. A PCB milling machine (referred to as a 'PCB Prototyper') operates in a similar way to a plotter, receiving commands from the host software that control the position of the milling head in the x, y, and (if relevant) z axis.
- Laser resist ablation Spray black paint onto copper clad laminate, place into CNC laser plotter. The laser raster-scans the PCB and ablates (vaporizes) the paint where no resist is wanted. (Note: laser copper ablation is rarely used and is considered experimental
Each trace consists of a flat, narrow part of the copper foil that remains after etching. The resistance, determined by width and thickness, of the traces must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces. In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in the form of stripline and microstrip with carefully controlled dimensions to assure a consistent impedance. In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; but they can be used as a deliberate part of the circuit design, obviating the need for additional discrete components.source: https://en.wikipedia.org/wiki/Printed_circuit_board


A Combined Experimental and Theoretical Investigation on the Fundamental Reaction Mechanisms of Cyanoborohydride Hypergolic Ionic Liquids with Key Oxidizers
The overall goal of this project is to explore experimentally and computationally the fundamental mechanisms involved in the oxidation of prototype cyanoborohydride (CBH) hypergolic ionic liquids (HILs) with key oxidizers (HNO3, H2O2). The proposed experiment utilizes a novel droplet merging technique coupled with an ultrasonic levitation device and computations (Prof. Rui Sun, University of Hawaii) highlighting the state-of-the-art reaction dynamics simulations with machine learning and enhanced sampling techniques. These findings are essential to the Air Force in the development of next-generation hypergolic ionic liquid-based chemical propulsion systems through pioneering, fundamental research including novel diagnostics technology and computational developments. These objectives are achieved by systematically initiating the reaction and ignition of HILs by merging levitated droplets of HILs with droplets of the oxidizer within a novel ultrasonic levitation device at relevant temperatures and pressures under container-less conditions - an emerging laboratory technique, which has not been accessible in previous HIL studies. The oxidation reaction between the HILs and oxidizers will be also unraveled at an atomistic level with ab initio molecule dynamics simulation accelerated by a novel machine learning technique; the condensed phased environment will be modeled in the presence of explicated solvent with cutting-edge enhanced sampling method. The tight experiment-computation collaboration proposed in this project determines hypergolic reaction mechanisms of ionic liquids and their dependencies on the oxidizer, identifies reaction critical intermediates that could explain the differences in ignition delays and defines the functional groups, which need to be present in the structure core of the ionic liquid, to enable ignition. Overall, this research will shed unprecedented light on the interplay between the structure of the HILs and its hypergolicity and provides insights into the mechanism of the ignition delay on the molecular level.


Light speed travel has been a staple of popular culture for years. I first became aware of the idea of light speed from watching Star Wars as a kid. But would we ever be able to actually travel at the speed of light? What would happen if we were able to achieve light speed travel?
First of all, traveling at the speed of light is most likely impossible. Because of Einstein’s famous equation E=mc^2, we know that energy and mass can be converted into each other. As the energy of an item increases because of its speed, its mass will also increase. Because of this, as an item gets closer to the speed of light, the item’s mass will approach infinity. Since its mass approaches infinity, the energy required to move it will also approach infinity, making it impossible to travel at the speed of light.
What would happen if we could get close to the speed of light? One thing that would change is our perception of time. If someone could travel at 90% of the speed of light, time for that person would be halved compared to someone observing from Earth. Another noticeable change would be your field of view. Someone traveling at close to the speed of light would experience serious tunnel vision due to a phenomenon known as Aberration. You would experience Aberration because the photons would appear to be coming from in front of you. You would also experience the Doppler Effect, where light waves crowd together, creating the blue color seen in a number of science fiction movies.
Even though the light speed travel from science fiction is impossible, traveling close to the speed of light would be a mind bending experience. For more in depth reading on the speed of light, check out this article on How Stuff Works.


One source of loss with a solar power system is the conversion of the DC power produced by the panels to the AC power used by the electric grid. This is done by a piece of equipment called an inverter, in my case an Eltek THEIA 3.8 HE-t UL. The manufacturer claims it is "up to 97.3% efficient," meaning that I'll lose at least 2.7% of the power produced by the panels. The specification for the inverter includes an efficiency curve showing how the efficiency varies depending on the amount of power being produced.
I was curious to see how my setup compared to the spec, so I pulled data for December 2013 through October 2014. I don't have the instantaneous numbers that are used in the spec (it would be quite a lot of work to collect and process all of that) and I don't have access to the direct data on the inverter, so I compared the DC power output from the Tigo power optimizers on the panels to the inverter output measure by my eGauge. I used daily totals for both numbers, then created a scatter plot of the efficiency versus the total power output for the day.
- Minimum: 58.45%
- Maximum: 95.08%
- Mean: 91.76%
- Median: 93.90%
The numbers are generally in line with with the spec though they tend to be a few percent lower. The low efficiency for low production days is one of the reasons that the winter is such a tough time for solar, since anywhere from 15 - 40% of the power coming from the panels can be lost due to conversion. Luckily that only works out to a handful of kilowatt-hours, and isn't a problem in the summer.


Google's Search Appliance hardware which can be used to index and search content not exposed to the internet like internal documents, has never really caught on. Though Google has never revealed the number of Search Appliances it has sold, most people agree that the number is not large. To bolster the sales of the search appliance Google has now released a virtual version of the appliance which can be run in Vmware.Its capabilities are limited compared to the hardware appliance.
It is free software download and is intended to be used as a platform for developers to build and test applications against Google enterprise search technology. Since it is intended only as a development platform, there is no support options available except developer forums.

Digital Camera Recovery
Recover Deleted mpeg from Digital Camera Without Delay
Digital cameras are widely used these days because of their smart features as well as easy usability where you can edit, delete or add other features to the images and videos that you have captured. These have become the first choice for professional as well as amateur photographers alike.
The images and videos that are captured are stored in the internal or external memory of the camera. In external storage of this data, these get stored in the memory card of the camera. However, there are also chances that the images and videos on the memory card can go missing or get deleted due to any reason. Such a situation can arise due to several reasons like accidentally or intentionally deleting or formatting the memory card, handling the device improperly, corruption in the memory card, virus attack, etc.
Due to these reasons one cannot access the data on the memory card. In such a situation one should immediately stop using the camera because the new images and videos that are captured overwrite the previous ones present on the memory card. Although the data is no more visible to the user, it is still there and only the pointers are no more found. Therefore, any new image or video would overwrite the previous ones.
So the question that arises here is can these videos be recovered back? The answer to this question is definitely in the affirmative and one can recover deleted mpeg from digital camera with the help of efficient software.
The software to recover deleted mpeg from digital camera can recover all lost and deleted MPEG videos from the memory card of the camera. The software makes use of strong scanning algorithms and scans the entire device to recover deleted mpeg from digital camera and ensure that each and every video is recovered with the data intact without the loss of any information.
One can use the software easily because it has a very user friendly Graphical User Interface that makes sure that you download and install the software without any difficulty. So the next time you delete any MPEG video from your digital camera do not despair but use the software to recover deleted mpeg from digital camera.
