Co-development agreement, brokered by MaRS Innovation, to advance ultrasound chemotherapy monitoring technology as clinical tool
TORONTO (March 12, 2015) — Sunnybrook Health Sciences Centre and MaRS Innovation today announced a co-development agreement for WaveCheck, an ultrasound technology that transforms conventional equipment so that physicians can monitor a breast cancer tumour’s response to chemotherapy.
The partnership with GE Healthcare, brokered by MaRS Innovation, seeks to develop WaveCheck as a clinical tool that gives clinicians rapid, improved transparency to determine if breast cancer tumors are responding to chemotherapy.
WaveCheck is a clinical technique invented, refined and tested by Dr. Gregory Czarnota, chief of Radiation Oncology at Sunnybrook’s Odette Cancer Centre, and Michael C. Kolios, professor of Physics and associate dean, Research and Graduate Studies, in Ryerson University’s Faculty of Science. Their technology uses ultrasound to visually demonstrate whether chemotherapy is destroying a breast cancer tumour at the beginning of chemotherapy treatment in as little as one week. If applied to the clinic, this knowledge has the power to transform patient experience, since existing breast cancer patients typically wait until the end of treatment, anywhere from four to six months, to know if their tumor has responded.
In early clinical testing, WaveCheck’s inexpensive, non-invasive, image-guided technology shows promise as an accurate, efficient way to monitor tumour response, opening the door to tailored treatment.
The agreement leverages GE Healthcare’s extensive ultrasound technology and market expertise in bringing new ultrasound innovations to global hospitals and clinics with Sunnybrook’s leadership in oncology research and cancer care through the Odette Cancer Centre.

Solid test processes
Production methods are essential for the correct industrialization of a product.
Product test processes are an essential part of an industrial activity. It is vital to ensure that each product complies with customer expectations. On our factories' assembly lines, the products are inspected individually to ensure they meet all acceptance requirements defined with the customer.
ALTYOR Group define the product test specifications with the customer. We then translate these functional test specifications into technical acceptance criteria. We work with our many partners who make test benches according to our criteria.
Choosing the right test process for each project depending on quantities
We can adjust test bench manufacturing to the planned quantities. For high work rates, the test benches will be highly automated and will require heavy investment. For smaller series, we can also work on test benches requiring more manual intervention, but with a more reasonable investment. When work rates increase, it is also possible to manufacture a simple test bench and then adjust it to the increase in volume.
Carefully planning the test bench is an essential part of product industrialization and must take place early on in the industrial design phase, particularly concerning electronics. It is impossible to manufacture a product without a test bench that can test all of the product's functionalities. All too often, this aspect is neglected and is not included in the product industrialization budget. ALTYOR Group attaches great importance to the quality of its test benches and to the completeness of the functionalities tested.

CALGARY, Alberta–(BUSINESS WIRE)–Groundwater wells are critical to our water infrastructure, particularly as we see new pressures such as water scarcity and climate change. These wells can turn into a grave environmental concern, however, when they are found to be a breeding ground for unsafe bacteria and chemical contaminants.
Arsenic, one of the most dangerous, can have a serious negative impact on the health of individuals who drink the water. Resolution does not come easy—just getting the water tested is challenging, and then there is the daunting prospect of arsenic remediation.
Making this process easier is FREDsense Technologies Corp (FREDsense), a Calgary-based company that recently deployed new portable water instrumentation technology for testing water. This technology allows utility managers to make decisions surrounding water quality parameters directly on-site, with just an hour’s wait, as opposed to the traditional delay for costly results from an off-site analytical lab.
In a case study released recently, FREDsense shared that the FRED-Arsenic test kit measured in the low parts per billion range (μg/L) and has been used by utilities and consultants in California and Arizona. The study showed there are many groundwater wells and active arsenic remediation efforts with successful outcomes. FRED-Arsenic is used by utilities, mining companies, and other industries to detect arsenic quickly and accurately in groundwater on site. The FRED-Arsenic Kit is designed to measure the concentration of total arsenic and inorganic arsenic species within a water sample and assess arsenic levels in water in the field within an hour of sampling.
“We are pleased to receive confirmation that the water quality test results from our FRED-Arsenic portable test kits were comparable to the samples taken in the same conditions and tested in a traditional lab. FREDsense is changing how the world approaches water quality monitoring and testing by creating test kits which are portable, can be used on site, and make it easier, faster, and more cost-effective to learn the contaminants in water and begin the remediation process,” said David Lloyd, co-founder and chief executive officer of FREDsense. “These test kits are just as accurate as the tests conducted in a lab.”
A recent project goal was to trial the FRED-Arsenic system in an on-site environment over two days at four groundwater wells. Water samples with varying levels of arsenic were tested using the FRED-Arsenic sensor and the results were compared with results from the same samples by a third-party analytical lab. This validated the use case of the technology and proved the accuracy of the sensor in the field. The study partner uses an analytical lab for measuring the arsenic levels upstream and downstream of the remediation systems and they often wait 1-2 weeks to receive data from the lab. They are interested in adopting an on-site testing system so their operators can make decisions about the remediation process directly in the field.
FRED-Arsenic results were compatible with the standard lab results, and the kit allows operators to get data in almost real-time. The test kit may be implemented across the entirety of their water quality testing infrastructure. FRED-Arsenic provided high-quality data comparable to that of the analytical lab (between ±1 – 2 μg/L). This revolutionizes how analytical chemistry is performed in-field, providing operators the opportunity to better understand their arsenic levels and to improve efficiency.
FREDsense was the recipient of an arsenic field kit challenge award through the United States Bureau of Reclamation as well as other awards for its technology. They are in the process of securing series A funding for the FRED-Arsenic technology and other critically needed water quality testing products they have in development.

ISO 17025 is an International Standard, used by testing and calibration laboratories, which specifies the general requirements for the competence to carry out tests and/or calibrations, including sampling. It covers testing and calibration performed using standard methods, non-standard methods, and laboratory-developed methods.
This standard, ISO/IEC 17025:2005, General requirements for the competence of testing and calibration laboratories, was first issued in 1999 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It was produced as the result of extensive experience in the implementation of ISO/IEC Guide 25 and EN 45001, both of which it replaced.
ISO 17025 contains all of the requirements that testing and calibration laboratories have to meet if they wish to demonstrate that they operate a management system, are technically competent, and are able to generate technically valid results. The standard requires laboratories to demonstrate continual improvement, perform regular internal audits to identify opportunities to make the test or calibration better and it drives the laboratory to keep abreast of scientific and technological advances in relevant areas.
The use of this standard applies to all organizations performing tests and/or calibrations. These include, first-, second- and third-party laboratories, and laboratories where testing and/or calibration forms part of inspection and product certification. ISO 17025 applies to all laboratories regardless of the number of personnel or the extent of the scope of testing and/or calibration activities. Laboratory customers, regulatory authorities and accreditation bodies may also use it in confirming or recognizing the competence of laboratories.
Laboratories that use this standard will be able to:
- Implement a quality system aimed at improving their ability to consistently produce valid results.
- Seek accreditation from an Accreditation Body.
- Demonstrate their customers and other interested parties that they are technically competent and able to produce precise and accurate test and/or calibration data.
- Operate in many countries where most labs must hold accreditation in order to be deemed technically competent. In many cases suppliers and regulatory authorities will not accept test or calibration results from a lab that is not accredited.
This standard incorporates those ISO 9001 requirements that are relevant to the scope of testing and calibration services that are covered by the laboratory’s management system; therefore, all testing and calibration laboratories that comply with ISO 17025 will also operate in accordance with ISO 9001.
The following referenced documents are indispensable for the application of ISO 17025:
- ISO/IEC 17000, Conformity assessment — Vocabulary and general principles
- VIM, International vocabulary of basic and general terms in metrology, issued by BIPM, IEC, IFCC, ISO, IUPAC, IUPAP and OIML.

In order to generate a robust and reliable library, all the spectra included in the database were measured using the same instrumental configuration and acquisition conditions.
The FTIR spectra were registered in attenuated total reflection (ATR) mode, using a SpectrumTwo FTIR spectrometer (PerkinElmer, Waltham, MA, USA) equipped with a GladiATR accessory (monolithic diamond ATR crystal from Pike Technologies). Spectra were collected in the 4000-380 cm−1 mid-infrared spectral region at 4 cm−1 resolution. A total of 128 scans were used for an optimal signal-to-noise ratio. All FTIR spectra have been baseline corrected and are plotted in percent transmittance (%T).
XRF measurements were performed using a TRACER III-SD portable energy-dispersive instrument from Bruker, provided with a Rh anode X-ray tube and a 10 mm2 X-Flash Silicon Drift Detector (SDD), with an energy resolution of approximately 147 eV for the Mn Kα line at 200,000 cps. For powder samples, approximately 5 g was used for each sample, in order to simulate an infinite layer thickness, placed directly onto Mylar film and exposed to X-rays for 300 s. The detection mode was universal, optimized for the mid-energy range of the 0-40 keV domain, experimental parameters being set at 40 kV tube voltage, ~11 μA current intensity, with no filtering of the incident beam, in air atmosphere. The instrument’s detection limit varies for each element as a function of the physics of the sample, down to ppm level.


Oxygen concentrators are ingenious devices that have revolutionized respiratory therapy, offering a continuous supply of oxygen to those in need. But how do these life-saving machines work? At the heart of their operation is a fascinating process that transforms ambient air into a more breathable, oxygen-rich form. Let's delve into the science behind oxygen concentrators and explore the principle of swing air absorption as an essential air purifying technique.
Ambient Air: The Starting Point
The air we breathe isn't pure oxygen; it's a mixture of gases, primarily nitrogen (approximately 78%), oxygen (around 21%), and small amounts of other gases. An oxygen concentrator begins its work by pulling this ambient air into the system, which serves as the raw material for oxygen production.
Compression and Filtration: Initial Steps
Once inside the machine, the ambient air is compressed to a high pressure. This step is critical as it prepares the air for the separation process by condensing the air and increasing the oxygen-to-nitrogen ratio. The compressed air is then passed through a series of filters to remove impurities, dust, and bacteria, ensuring the air entering the next stage is clean and ready for oxygen extraction.
The Heart of the Machine: Swing Air Absorption
The core technology behind oxygen concentrators is a process known as Pressure Swing Adsorption (PSA). This technique leverages the unique properties of a material called zeolite, a microporous mineral with the remarkable ability to selectively adsorb nitrogen from the air.
In a typical PSA system, the concentrator contains two zeolite-filled towers. As compressed air flows into the first tower, the zeolite beads adsorb nitrogen, allowing oxygen, which is not absorbed, to pass through. This results in a stream of oxygen-enriched air available for the patient. Meanwhile, the second tower stands by in a regenerative phase, releasing the trapped nitrogen back into the atmosphere through a depressurization process.
This "swing" between adsorption and regeneration between the two towers allows the concentrator to produce a continuous flow of oxygen. The rapid cycling between the two states—pressure (adsorption) and release (desorption)—ensures an uninterrupted supply of purified oxygen.
Advancements and Efficiency
Modern oxygen concentrators are designed to be highly efficient, utilizing advancements in materials science and engineering to enhance the PSA process. They can adjust the flow rate and purity level according to the patient's needs, providing a tailored respiratory therapy experience.
Furthermore, recent developments aim to reduce the size, noise, and power consumption of these devices, making oxygen therapy more accessible and comfortable for users worldwide.
Environmental Impact and Energy Use
An additional benefit of oxygen concentrators is their environmental friendliness compared to traditional oxygen tanks. By utilizing ambient air, concentrators eliminate the need for tank refills or liquid oxygen deliveries, reducing the carbon footprint associated with transportation and production.
However, as electrical devices, the energy efficiency of oxygen concentrators is a topic of ongoing improvement. Manufacturers and researchers continue to strive for models that offer the highest oxygen output with the lowest possible energy consumption.
Conclusion: A Breath of Fresh Air
The science behind oxygen concentrators showcases a brilliant application of physical principles and materials science to meet a critical healthcare need. The PSA technology, particularly the swing air absorption process, exemplifies how advanced engineering can transform everyday air into a life-sustaining resource. As technology advances, these devices will continue to improve, offering better, more efficient, and more accessible treatment options for those requiring oxygen therapy.
In essence, oxygen concentrators embody a significant scientific leap, turning the air around us into a vital source of health and well-being.


The purpose of the motor is to create torque and ultimately the rotational motion of other equipment. The torque depends on a flux wave in the air gap and the relative speed of the rotor to this flux wave. The strength of the flux wave depends on the voltage and frequency applied across the stator terminals, as shown in Equation 1:
Ø = V/f
A load applied to a motor reduces the speed of the rotor (increased slip). The speed becomes constant when the motor torque matches the load torque but the rotor stalls if the load exceeds the maximum torque (breakdown torque).
A VFD controls both voltage and frequency to produce a constant flux, thereby maintaining maximum torque at various speeds. The VFD rectifies the AC power in the inverter module, then converts it back to AC power by wave modulation.
In this process, harmonic waves and short duration insulation erosion voltage spikes are also generated in amplitudes depending on the carrier frequency of the VFD and its circuitry, as well as any included filtering, if necessary. The output voltage of a VFD is critical information for the motor manufacturer. The motor manufacturer should consider the effects of the VFD in terms of size, cost, and best motor-VFD performance. Here are the key points to consider when designing a custom motor to run on a VFD.
The flux and current density create a current concentration at the top of each rotor bar (skin effect). This effect is responsible for generating the starting torque (locked rotor torque) and keeping the starting current (locked rotor current) below a target value during acceleration of the mains-powered motor.
When it comes to a VFD, the skin effect is no longer relevant to allowing a motor to accelerate and maintain low starting current. Nevertheless, it is necessary to limit the time harmonic generated by the VFD due to its ability to create heat losses. However, the breakdown torque is critical and must match the needs of the application for fast speed response, loading, and achieving the desired speed in the targeted constant power region.
Proper sizing of the rotor is essential. Increasing the number of bars of the rotor or its length, thus also changing the dimensions of the stator, are examples of design adjustments to increase torque. The VFD must supply enough current to generate the required torque during normal and overload operation, but a motor specially designed to match a VFD can limit the current to avoid applying a larger and more expensive VFD. This action results in a lower system acquisition cost.
When mains power is supplied to a motor, slot magnetic leakage saturation, rotor static and dynamic eccentricities, and number of rotor and stator slots, among others, can generate harmonics at the fundamental frequency. The results are mechanical losses and stresses, which the harmonics introduced by the VFD increase in quantity. These harmonics create parasitic radial torque, leading to additional vibration and heat if not taken into account in the motor design.
The electricity consumption of industrial electric motors is increasingly becoming a critical criterion in motor design. Many countries have regulations for small AC induction motors (below 375kW) because they represent, by far, the largest amount of induction motors in operation and therefore have the most impact on electricity consumption.
Although there are no regulations for large machines up to several megawatts, efficiency is relevant as they are responsible for 23% of electricity consumption.¹
Efficiency is the ratio between the power delivered to the shaft and the input power at the motor terminals. The International Electrotechnical Commission (IEC) 60034-2-1 and the Institute of Electrical and Electronics Engineers (IEEE) 112 have helped industries develop test procedures to determine the efficiency of motors by testing or calculating losses. The efficiency test includes the determination of motor losses called:
- I²R stator
- friction and drift
- core losses
- parasitic load losses
Parasitic load losses, which occur on stator and rotor cores and other metal parts, eddy current loss in rotor bars and stator windings are difficult to predict and measure. Considering the harmonics generated by the VFD complicates this challenge.
The heat dissipation capacity is a determining factor in the size of the machine and the respect of its temperature rise class. The motor manufacturer should design an efficient internal airflow path and provide independent external air cooling for constant torque applications.
Standard bipolar motors have a critical speed below their rated speed, which resonates amplifying vibration to the point of equipment damage if the drive operates the motor at or near critical speed. The motor manufacturer will need to know if the operating speed range will cross the critical speed to provide a solution which may be vibration damping, modification of the motor critical speed or programming the VFD to avoid the critical speed region .
The voltage waveform provided by the VFDs consists of pulses with rapidly rising peaks, behaving like surges in the connected motor winding. These differ from regular sine waves. The impedance mismatch between the power leads and the stator will increase the voltage by reflection. Over time, the stator insulation will deteriorate and fail if these fast growing spikes are not addressed.
An actual waveform representing total harmonic distortion is valuable information but not always provided, requiring the motor manufacturer to make assumptions. Overestimating or underestimating the harmonics leads to an additional cost for the user. In the absence of such data, a manufacturer may decide not to offer an engine due to the high level of risk.
Motors and drives
Sourcing a motor and variable frequency drive (VFD) from the same manufacturer can offer advantages. Medium voltage motors over 375 kilowatts (kW), up to several megawatts, are made-to-order, custom-designed, and expensive. Combining a motor with a VFD system designed and produced by the same manufacturer can offer:
- maximum system longevity
- reliable and continuous operation
- reduced electricity consumption
If the motor and the VFD are from separate sources, an efficient exchange of information between the equipment suppliers and the system integrator is necessary to match the specified system application results.
The decision factors above do not cover all aspects when designing an electric motor or integrating a VFD, but are provided to demonstrate the complexity of the custom motor design process, which can encourage the integrator or end user to purchase the equipment from the same manufacturer.

Health professionals around the world use this non-invasive, low level laser therapy to help patients suffering from a range of pain conditions.
Low level laser therapy, also known as photobiomodulation or cold laser, uses low intensity lasers and light emitting diodes(LEDs) at the infrared and visible red wavelengths to relieve pain and reduce inflammation caused by damaged tissue.
Low level laser therapy works by accelerating the body’s natural healing mechanisms. When low level laser light particles penetrate the skin, the damaged cells absorb the light and convert it into energy (a photochemical reaction similar to the way skin absorbs sunlight to produce vitamin D). The body uses this energy to reduce inflammation and increase blood flow, assisting the natural healing process.


Exploring the Mysteries of Jupiter’s Transit in April 2023
Jupiter, the largest planet in our solar system, has always fascinated astronomers and space enthusiasts alike. Its massive size, distinct bands of clouds, and iconic Great Red Spot make it a captivating subject for study. But in April 2023, a rare celestial event is set to occur – a transit of Jupiter. This transit presents a unique opportunity for scientists and stargazers to delve deeper into the mysteries of this gas giant.
So, what exactly is a transit? A transit occurs when a celestial body passes directly between an observer and a more distant object, partially obscuring the latter. In the case of Jupiter’s transit, it will pass in front of the Sun, casting a small shadow onto our planet. This rare occurrence offers a chance to study Jupiter’s atmosphere, magnetic field, and other intriguing features in greater detail.
One of the primary goals of studying Jupiter’s transit is to gather data about its atmosphere. By observing the sunlight passing through the planet’s atmosphere, scientists can analyze the absorption and scattering of light. This information can provide valuable insights into the composition of Jupiter’s clouds, as well as the presence of various gases and particles. Studying the changes in the sunlight can also help determine the size and distribution of particles in the planet’s atmosphere.
Furthermore, the transit allows astronomers to study Jupiter’s magnetic field. Jupiter boasts the strongest magnetic field of any planet in our solar system, producing intense radiation belts. The transit provides an opportunity to observe how the planet’s magnetic field interacts with the Sun’s magnetic field, shedding light on the processes that generate and sustain Jupiter’s powerful magnetosphere.
Another mystery to explore during the transit is the Great Red Spot, a massive storm that has been raging on Jupiter for centuries. By studying the transit, scientists hope to gain a better understanding of the storm’s dynamics and its impact on the surrounding atmosphere. Additionally, the transit may reveal any changes in the size, shape, or intensity of the Great Red Spot, helping scientists trace its evolution over time.
To observe Jupiter’s transit in April 2023, astronomers and space agencies around the world will utilize a range of instruments and techniques. Telescopes equipped with specialized filters will be used to safely observe the Sun and Jupiter simultaneously. Space-based observatories, such as the Hubble Space Telescope, will also contribute to the study, capturing high-resolution images and spectroscopic data.

RIE Technology and Applications
Plasma etching allows for the removal of etching of various surfaces in vacuum-based techniques, and reactive ion etching (RIE) is used for semiconductor device manufacturing, making it a specialty machine. With the aid of reactive ion etching, it is possible to etch materials by accelerating ions toward the substrate.
As mentioned above, reactive ion etching is used in vacuum-based techniques, and the necessary equipment for RIE is mounted around vacuum chambers. The reactive ion etching equipment includes two electrodes (anode and cathode) that create an electric field around the vacuum chamber.
The electric field accelerates the ions they produce toward the substrate surface, and when process gases go into the vacuum chamber through the top electrode. The reactor is then evacuated by a special vacuum pump.
During the etching process, samples are masked by patterning processes and then placed inside the vacuum chamber. Then, gases are introduced into the vacuum chamber and activated by microwave or RF power. The power surge produces plasma that consists of ions, electrons, and reactive species.
The energy that the reactive ion etching equipment produces enhances the chemical reaction's effectiveness and creates the direction in which the etching will occur.
The reactive ion etching equipment is applied for the etching of various materials and particles, including the following:
- Silicon-based materials
- Dielectric materials
- III-V materials
Based on process parameters, one can optimize and adjust settings in the RIE equipment, such as pressure, gas flow, RF power, etc. Also, the types of film that meant to be etched should also be considered when designing process chemistries.
For instance, metal etching requires chlorine-based chemistries and dielectric etch applications require fluorine-based chemistries.
To achieve the desired results, it is necessary to use the most suitable reactive ion etching equipment for the materials applied in the process.

The rise of 4K technology has revolutionized the film industry, providing filmmakers with an unprecedented level of detail and clarity. With four times the resolution of standard HD, 4K cameras capture images with stunning precision and lifelike quality. This has opened up new creative possibilities for filmmakers, allowing them to capture even the most subtle details in their shots. But 4K technology is not just limited to the film industry; it has also found its way into other fields such as sports broadcasting, surveillance, and even gaming. As more and more devices adopt this technology, it’s clear that 4K is here to stay. In this blog post, we will explore the recent advancements in image sensors, processors, and HDR technology that have made pro 4K cameras even more powerful tools for capturing stunning visuals.
Advancements in Image Sensors and Processors
The advancements in image sensors and processors have played a significant role in enhancing the quality of 4K cameras. With the rise of 4K technology, manufacturers have been working tirelessly to improve the image sensors used in these cameras. The latest image sensors are designed to capture more light, resulting in brighter and clearer images.
One of the most significant advancements in image sensors is the introduction of back-illuminated (BSI) sensors. Unlike traditional front-illuminated sensors that have wiring and transistors blocking some light from reaching the sensor, BSI sensors move these components behind the photodiodes, allowing more light to reach the sensor. This results in better low-light performance, reduced noise levels, and improved color accuracy.
Another notable improvement is the use of larger sensor sizes. Larger sensors can capture more light, resulting in better dynamic range and less noise. While full-frame sensors were once reserved for high-end cameras, they are now becoming more common even in consumer-grade 4K cameras.
In addition to improvements in image sensors, processors also play a crucial role in enhancing image quality. The processor is responsible for processing the data captured by the sensor into a final image or video. With faster processors, cameras can capture higher frame rates and process larger amounts of data quickly.
One example of a powerful processor used in 4K cameras is the Bionz X processor from Sony. This processor is capable of processing large amounts of data quickly while delivering high-quality images with minimal noise levels.
Another feature that has become increasingly popular among camera manufacturers is dual processors. Dual processors allow for faster processing speeds and better overall performance when capturing high-resolution videos or images.
High Dynamic Range (HDR) Technology
High dynamic range (HDR) technology is a recent advancement in the field of digital imaging. HDR technology allows for a greater range of brightness and color to be captured, resulting in more realistic and visually stunning images. This technology has been incorporated into many 4K cameras, making them capable of producing high-quality images with exceptional detail and clarity.
What is HDR?
HDR technology works by capturing multiple exposures of the same image at different brightness levels. These images are then combined to create a single image that contains a wider range of brightness and color than would be possible with a single exposure. The result is an image that appears more true-to-life, with greater detail in both highlights and shadows.
HDR technology has become increasingly popular in recent years as more devices have become capable of displaying HDR content. Many modern televisions, computer monitors, and mobile devices support HDR, allowing viewers to experience the full range of colors and brightness captured by HDR-enabled cameras.
Benefits of HDR
One of the primary benefits of HDR technology is its ability to capture more detail in both bright and dark areas of an image. This means that images captured with HDR-enabled cameras appear more realistic and visually striking than those captured without this technology.
HDR also allows for greater flexibility when it comes to post-processing images. Because HDR captures multiple exposures at different brightness levels, photographers can adjust the exposure settings after the fact to achieve the desired look without sacrificing detail or quality.
Another benefit of HDR is its ability to accurately reproduce colors. By capturing a wider range of colors than traditional imaging techniques, HDR ensures that colors appear vibrant and true-to-life in final images.
Potential Applications of 4K Technology
As technology continues to advance, the potential applications of 4K technology are becoming more and more apparent. From film and television to photography, there are numerous ways in which 4K cameras can be used to enhance image quality and create stunning visuals.
Film and Television
One of the most obvious applications of 4K technology is in the film and television industry. With the rise of streaming services like Netflix and Amazon Prime Video, there is a growing demand for high-quality content that can be streamed on large screens. This means that filmmakers need to produce content that is not only visually stunning but also has a high resolution.
4K cameras allow filmmakers to capture images with four times as many pixels as traditional HD cameras. This means that they can capture more detail, which results in sharper images with greater depth and clarity. In addition, 4K cameras have a wider color gamut than traditional HD cameras, which means they can capture more colors and shades.
Another advantage of using 4K cameras in filmmaking is that they allow for greater flexibility in post-production. Filmmakers can crop or zoom into footage without losing resolution or quality, which gives them more creative control over their final product.
While 4K technology is often associated with video production, it also has numerous applications in photography. One area where it has been particularly useful is in sports photography.
Sports photographers often need to capture fast-moving subjects in low-light conditions. This can be challenging with traditional cameras because they struggle to capture enough light quickly enough. However, 4K cameras have larger image sensors than traditional cameras, which allows them to capture more light and produce clearer images even in low-light conditions.
In addition to sports photography, 4K cameras are also being used for landscape photography. With their ability to capture fine details and vivid colors, they allow photographers to create stunning images that are full of depth and texture.
In conclusion, the advancements in 4K technology have revolutionized the film and photography industry. With the introduction of high-quality image sensors and processors, along with HDR technology, professionals can now capture stunning visuals with unparalleled detail and clarity. The potential applications of 4K technology are vast, from virtual reality to medical imaging and beyond. As the technology continues to evolve, we can expect even more impressive features and capabilities in the future. Overall, pro 4K cameras have changed the game for visual storytelling, providing creators with powerful tools to bring their visions to life in ways never before possible.

Rapid and accurate bacterial detection methods are needed for clinical diagnostic, water, and food testing applications. The wide diversity of bacterial nucleases provides a rich source of enzymes that could be exploited as signal amplifying biomarkers to enable rapid, selective detection of bacterial species. With the exception of the use of micrococcal nuclease activity to detect Staphylococcus aureus, rapid methods that detect bacterial pathogens via their nuclease activities have not been developed. Here, we identify endonuclease I as a robust biomarker for E. coli and develop a rapid ultrasensitive assay that detects its activity. Comparison of nuclease activities of wild-type and nuclease-knockout E. coli clones revealed that endonuclease I is the predominant DNase in E. coli lysates. Endonuclease I is detectable by immunoblot and activity assays in uropathogenic E. coli strains. A rapid assay that detects endonuclease I activity in patient urine with an oligonucleotide probe exhibited substantially higher sensitivity for urinary tract infections than that reported for rapid urinalysis methods. The 3 hr turnaround time is much shorter than that of culture-based methods, thereby providing a means for expedited administration of appropriate antimicrobial therapy. We suggest this approach could address various unmet needs for rapid detection of E. coli.

In pursuit of unraveling the mysteries of Fast Radio Bursts, a new telescope will bring engineers at West Virginia University one step closer to an explanation.
Thanks to a $1.7 million National Science Foundation grant awarded to Kevin Bandura, assistant professor in the Lane Department of Computer Science and Electrical Engineering in the Statler College of Engineering and Mineral Resources, a new telescope is slated to be built at the Green Bank Observatory to pinpoint the locations of FRBs in far off galaxies, enabling the ability to finally discover the nature of these enigmatic objects.
FRBs are among the brightest sources ever seen in the sky, but their origin remains a mystery to scientists. The intense flashes of energy blaze for only a millisecond and then disappear. Although they can only be seen for a brief moment, the radio waves have travelled for billions of years through an ionized cosmic structure to be visible in the sky.
“Currently, most FRB positions are so imprecise that astronomers don’t even know which galaxy they come from,” Bandura said. “The new telescope, Outrigger, will solve that problem, determining the particular galaxy, and will go further, localizing the source to a specific region within the galaxy.”
The new Outrigger telescope will work in conjunction with the existing Canadian Hydrogen Intensity Mapping Experiment, or CHIME, telescope, which is located half a continent away in British Columbia, to triangulate the locations of FRBs.
“The CHIME telescope will be making the detection, but the data will be saved from both telescopes, then we can use very long baseline interferometry techniques to really localize where it comes from,” Bandura said.
The CHIME telescope is comprised of four cylindrical reflectors, 256 dual-polarized antennas for data collection and an F-engine and X-engine for data processing. To search for FRBs, CHIME continuously scans 1024 separate points on the sky. The new Outrigger telescope will have only one cylinder but will monitor the same area of the sky as the original CHIME telescope.
“From this, we will be able to understand a lot about what is happening between us and the FRB,” Bandura said. “So, if we can actually localize where it is and understand where it came from, we can use that information from the detection to understand what’s in between us and the source.”
The development of this program will open the door for additional outriggers to be built later, allowing even sharper localization of radio bursts, and will pave the way for future construction of larger low-cost, high-throughput telescopes for more advanced transient searches and intensity mapping efforts to probe deeper into the cosmos.

The patented CME Continuous Sample Tube System is a sampling device that was developed to provide continuous sampling when drilling with hollow-stem augers. The specimen enters the sampler barrel as the augers are advanced. Drilling fluids or air are not required.
The CME Continuous Sample Tube System consists of a 3″ x 5 ‘ sample tube with a cutting shoe that extends below the auger cutter head. The sample tube is operated on a hexagonal shank-and-socket drill stem column. The shank-and-socket drill stems are connected through a bearing assembly to the drill rig feed system and to a stabilizer plate to positively prevent rotation of the sample tube with rotation of the hollow stem augers. The first drill stem in the column has an adjustable length for varying the amount the sampler protrudes below the auger cutter head.
The stabilization of the sample tube, the tube extension adjustments and the clearance ratio of the cutting shoe with the sample tube are all important to sample recovery and sample quality. Tube stabilization has proven to be very important in providing the most consistent and highest quality sample.
Both clear plastic liners and steel liners can be used inside the sample tube to retain the sample. The use of the clear plastic liners allows you to visually examine the sample in the field and yet keep it contained for transport to a lab and later testing. The clear plastic liners can be reused several times.
The CME Continuous Sample Tube System has been used very successfully on many projects for various purposes in a variety of soil types. With this sample system, very efficient continuous sampling can be performed to provide a complete soil profile. Obtaining 95 to 100 percent recovery is more the rule than the exception. The variety of materials that can be sampled include silt, clay, some granular soils, glacial till, coal, shale, mine tailings and others.
One type of project where the continuous sample is used extensively is environmental projects where chemical or radiological contamination is suspected. Most of these projects desire or require high quality continuous samples and this can be achieved very adequately with the continuous samplers.

ARTERY published a new scientific paper on “Path Tracking Control of a Steerable Catheter in Transcatheter Cardiology Interventions”
The study, conducted in collaboration between Politecnico di Milano and KU Leuven, focuses on improving transcatheter interventions for mitral regurgitation by developing a path tracking control framework for autonomous navigation of a robotic steerable catheter through vascular lumens.
This method involves a kinematic model that considers nonholonomic constraints and utilizes real-time data from electromagnetic and fiber Bragg grating sensors to guide the catheter with precision. Tested in a patient-specific vessel phantom, the framework achieved a median position error under 2 mm, demonstrating high accuracy in catheter navigation.
This research represents a significant step forward in transcatheter interventions, offering promising avenues for improving patient outcomes in mitral regurgitation treatment.

Ultrawave's SMART Generators are a digitally controlled power source for Ultrawave Submersible Transducers.
The technically advanced Smart Gens allow variables such as power output and cycle time to be controlled by the operator via a digital control panel. The operator can then ensure the correct frequency and power is inputted for particular tanks and submersibles to be set for optimum ultrasonic cleaning activity throughout the tank.
The SMART Generators incorporate Frequency Leap Technology to provide improved cleaning results. This is achieved by a pseudo-random leaping action between a wider frequency range, reducing the standing waves and improving cleaning activity.
Available incorporated into the machine or as remote wall mounted or cabinet located options, Ultrawave's SMART Generators deliver precise and consistent control to your ultrasonic cleaning system.

The ASRT recently released the following important position statements:
Digital Imaging Cropping or Masking in Radiography
It is the position of the American Society of Radiologic Technologists that a digital image should not be cropped or masked such that it eliminates areas of exposure from the image that are presented for interpretation. Pre-exposure collimation of the x-ray beam is necessary to comply with the principle of as low as reasonably achievable (ALARA). To determine that exposed anatomy on an image is not significant or of diagnostic value is a medical decision and is therefore outside of the scope of practice for a radiologic technologist.
Adopted, Main Motion, C-14.10, 2014
Digital Image Post-Processing in Radiography
It is the position of the American Society of Radiologic Technologists that an image obtained for a prescribed projection in a digital imaging system or series be assigned only to that specific projection and not be altered by post-processing in order to be represented as another projection.
Adopted, Main Motion, C-14.07, 2014
Monitoring Patient Exposure During Utilization of Digital Radiography Systems
It is the position of the American Society of Radiologic Technologists that health care facilities using digital radiography systems monitor patient exposure. Exposure indicator data should be included in the Digital Imaging Communication in Medicine (DICOM) header for images sent to picture archiving and communication systems (PACS) or in the patient demographics field for all imaging studies and should be part of the permanent patient record. The exposure indicator should not be altered to modify image appearance and should accurately record the exposure or exposure factors used in producing the image. Health care facilities should collect patient exposure range distributions and reject analyses as part of the quality assurance program. This exposure data should be reviewed routinely by the health care facility.
