Tactical Grade Gyroscope Performance in a Consumer Grade Process Slides
Creators: Bernhard Boser
Publisher: name: IEEE
Year: 2018

SSCS Webinar
Abstract
GPS has transformed navigation but unfortunately does not work in indoor or dense urban environments. The alternative, inertial navigation, is either too inaccurate or too large, power hungry, and costly in all but niche applications.

Gyroscopes are responsible for direction in inertial sensors. Since even small angular offsets can rapidly add up to large location errors, significantly improved gyroscope accuracy is the key to precise indoor navigation.

I will describe a prototype gyroscope with tactical grade performance. Unlike state of the art solutions, the device does not rely on exotic fabrication technology or trimming, and both its size and power dissipation are comparable to existing mobile solutions.

How this is possible
Sensors, in general, compare their input to a reference. A thermometer compares its input to a reference temperature and reports the ratio. Gyroscope sensors have a huge advantage: their input is rate, degrees per second, also known as frequency. Frequency is the physical quantity that we can synthesize and measure with highest accuracy. While ppm-level precision is out-of-the-question for most properties, it is easily achieved for frequency.

Why then are gyroscopes not just as accurate as frequency sources
Oddly, present MEMS gyroscopes first convert frequency into force, then displacement, capacitance, voltage. Not only are these quantities difficult to measure with high accuracy, the scaling factors of all these transformations are subject to a myriad of fabrication and environmental variations. Not surprising that present gyroscopes suffer from a few errors.

The path to good gyroscopes is to measure frequency directly, without performance compromising detours. In this presentation, I will show you how.

ABSTRACT Brain disease is a growing socioeconomic problem. In the US, chronic pain affects over 100 million people, with over 600B annual cost. Alzheimer's disease affects 5.4 million people, with the cost of care exceeding sales of Google. Another 5 million live with long term disability as a result of traumatic brain injury, and there are millions with epilepsy. Drug therapy has failed. The development of neuromodulation technology has become a major medical and social priority. While much progress has been made in generating brain machine interface and restoring limb movement, it is much more difficult to restore memories, especially declarative memories, or treat network scale neuropsychiatric indications. Fueled by insights from clinical neuroscience and engineering, I will discuss a leading edge technology that can make the fulfillment of memory restoration and the treatment of neuropsychiatric symptoms highly likely.

description: The competition of magnetic order and superconductivity is a key element in the physics of all unconventional superconductors, e.g. in high-transition-temperature cuprates 1, heavy fermions 2 and organic superconductors3. Here superconductivity is often found close to a quantum critical point where long-range antiferromagnetic order is gradually suppressed as a function of a control parameter, e.g. charge carrier doping or pressure. It is believed that dynamic spin fluctuations associated with this quantum critical behaviour are crucial for the mechanism of superconductivity. Recently high-temperature superconductivity has been discovered in iron-pnictides providing a new class of unconventional superconductors4,5,6. Similar to other unconventional superconductors the parent compounds of the pnictides exhibit a magnetic ground state7,8 and superconductivity is induced upon charge carrier doping. In this Letter the structural and electronic phase diagram is investigated by means of x-ray scattering, MuSR and Moessbauer spectroscopy on the series LaO1-xFxFeAs. We find a discontinuous first-order-like change of the Neel temperature, the superconducting transition temperature and of the respective order parameters. Our results strongly question the relevance of quantum critical behaviour in ironpnictides and prove a strong coupling of the structural orthorhombic distortion and the magnetic order both disappearing at the phase boundary to the superconducting state.

Design Techniques for Scalable, Sub-pJ/b Serial I/O Transceivers Slides
Creators: Samuel Palmero
Publisher: name: IEEE
Year: 2018

SSCS Webinar
Abstract
In order to meet the inter chip bandwidth demands of future systems and comply with limited IC power budgets, both chip to chip data rates and IO energy efficiency must improve. This is a significant challenge for electrical interconnect architectures, which currently offer the lowest cost solutions, as the frequency dependent loss of conventional electrical channels prohibit significant data rate scaling without efficient equalizer circuits. This talk will discuss key design techniques that enable scalable, low power serial IO transceivers. The first part of the talk will discuss low power transmitter and receiver designs capable of low voltage operation and fast power state transitioning. Next, low complexity clocking architectures are detailed. The talk concludes with a discussion on low power equalizer circuits that enable the support of higher data rates over lossy channels.

description: The magnetic relaxation processes in disordered two-dimensional ensembles of dipole-coupled magnetic nanoparticles are theoretically investigated by performing numerical simulations. The energy landscape of the system is explored by determining saddle points, adjacent local minima, energy barriers, and the associated minimum energy paths (MEPs) as functions of the structural disorder and particle density. The changes in the magnetic order of the nanostructure along the MEPs connecting adjacent minima are analyzed from a local perspective. In particular, we determine the extension of the correlated region where the directions of the particle magnetic moments vary significantly. It is shown that with increasing degree of disorder the magnetic correlation range decreases, i.e., the elementary relaxation processes become more localized. The distribution of the energy barriers, and their relation to the changes in the magnetic configurations are quantified. Finally, some implications for the long-time magnetic relaxation dynamics of nanostructures are discussed.

description: We present the results of a uniform search for additional planets around all stars with confirmed hot Jupiters observed by the Transiting Exoplanet Survey Satellite (TESS) in its Cycle 1 survey of the southern ecliptic hemisphere. Our search comprises 184 total planetary systems with confirmed hot Jupiters with $R_{p}$ > 8$R_\oplus$ and orbital period < 10 days. The Transit Least Squares (TLS) algorithm was utilized to search for periodic signals that may have been missed by other planet search pipelines. While we recovered 169 of these confirmed hot Jupiters, our search yielded no new statistically-validated planetary candidates in the parameter space searched (P < 14 days). A lack of planet candidates nearby hot Jupiters in the TESS data supports results from previous transit searches of each individual system, now down to the photometric precision of TESS. This is consistent with expectations from a high eccentricity migration formation scenario, but additional formation indicators are needed for definitive confirmation. We injected transit signals into the light curves of the hot Jupiter sample to probe the pipeline's sensitivity to the target parameter space, finding a dependence proportional to $R_{p}^{2.32}P^{-0.88}$ for planets within 0.3$\leq$$R_{p}$$\leq$4 $R_\oplus$ and 1$\leq$$P$$\leq$14 days. A statistical analysis accounting for this sensitivity provides a median and $90\%$ confidence interval of $7.3\substack{+15.2 \\ -7.3}\%$ for the rate of hot Jupiters with nearby companions in this target parameter space. This study demonstrates how TESS uniquely enables comprehensive searches for nearby planetary companions to nearly all the known hot Jupiters.

Painlevé V and a Pollaczek-Jacobi type orthogonal polynomials

Year: 2008
Subjects: subject: Classical Analysis and ODEs (math.CA)

description: We study a sequence of polynomials orthogonal with respect to a one parameter family of weights $$ w(x):=w(x,t)=\rex^{-t/x}\:x^{\al}(1-x)^{\bt},\quad t\geq 0, $$ defined for $x\in[0,1].$ If $t=0,$ this reduces to a shifted Jacobi weight. Our ladder operator formalism and the associated compatibility conditions give an easy determination of the recurrence coefficients. For $t>0,$ the factor $\rex^{-t/x}$ induces an infinitely strong zero at $x=0.$ With the aid of the compatibility conditions, the recurrence coefficients are expressed in terms of a set of auxiliary quantities that satisfy a system of difference equations. These, when suitably combined with a pair of Toda-like equations derived from the orthogonality principle, show that the auxiliary quantities are a particular Painlevé V and/or allied functions. It is also shown that the logarithmic derivative of the Hankel determinant, $$ D_n(t):=\det(\int_{0}^{1} x^{i+j} \:\rex^{-t/x}\:x^{\al}(1-x)^{\bt}dx)_{i,j=0}^{n-1}, $$ satisfies the Jimbo-Miwa-Okamoto $σ-$form of the Painlevé V and that the same quantity satisfies a second order non-linear difference equation which we believe to be new.

Energy Efficient Nyquist-Rate ADCs-Slides

Publisher: name: IEEE
Year: 2020

SSCS Webinar Slides
Abstract:
In large SoC’s, data converters take a dominant position both from a performance point of view as well as from an energy consumption point of view. The past two decades have shown a strongly intensified search for more power efficient data converters, in particular power efficient ADCs. This presentation will focus on power efficiency of Nyquist-rate ADCs and discuss what has been proposed in open literature to reduce the energy consumption, both from a circuit point of view as well as from an architectural point of view. To get a good grasp of how circuit and architectural choices affect the power consumption, a method will be introduced that allows a quick estimation of the power consumption of an ADC, based on the required SNDR, the sampling frequency, the used technology as well as the chosen ADC architecture and circuit implementations. The proposed method enables a comparison based on these choices and can show what their impact is on the power efficiency, without going through the elaborate design of several architectures. It also shows which recent inventions made a large impact on power efficiency and how these inventions can also be of use in other architectures than the ones they have been introduced in.

description: Cluster-assembled metallic films show interesting electrical properties, both in the near-to-percolation regime, when deposited clusters do not form a complete layer yet, and when the film thickness is well above the electrical percolation threshold. Correctly estimating their electrical conductivity is crucial, but, particularly for the latter regime, standard theoretical tools are not quite adequate. We therefore developed a procedure based on an atomically informed mesoscopic model in which ab-initio estimates of electronic transport at the nanoscale are used to reconstruct the conductivity of nanogranular gold films generated by molecular dynamics. An equivalent resistor network is developed, appropriately accounting for ballistic transport. The method is shown to correctly capture the non-monotonic behavior of the conductivity as a function of the film thickness, namely a signature feature of nanogranular films.

description: We are facing a major skills gap within the construction sector and there is a pressing need for upskilling in circular skills after identifying the existing skills gaps. Using Multi-functional Green Roofs Facades and Interior Elements (MGRFIE) as a pilot case, the BUS-GoCircular project has mapped the circular skills gaps that currently exist throughout Europe. This has created the basis for the development of the task-based Qualification Framework, resulting in 80 Units of Learning Outcomes (ULOs) required to upgrade circular skills. This then supports the creation of training packs and training programs to upskill professionals within the sector. Through our research we discover that there are skills gaps existing within every profession across the sector meaning training must be provided for all professions to bridge these gaps. Training packs for small and medium enterprises (SMEs) and materials were created with this in mind and are now playing an important role in Train the Trainer (TtT) programs as well as mentoring programs being carried out across Europe.

description: Using a sample of 68 million KL -> 3pi0 decays collected in 1996-1999 by the KTeV (E832) experiment at Fermilab, we present a detailed study of the KL -> 3pi0 Dalitz plot density. We report the first observation of interference from KL->pi+pi-pi0 decays in which pi+pi- rescatters to 2pi0 in a final-state interaction. This rescattering effect is described by the Cabibbo-Isidori model, and it depends on the difference in pion scattering lengths between the isospin I=0 and I=2 states, a0-a2. Using the Cabibbo-Isidori model, we present the first measurement of the KL-> 3pi0 quadratic slope parameter that accounts for the rescattering effect.

Furthermore, we showcase the different use-cases for the bi-gram graphs and how scalable it proves to be when dealing with large datasets.

New Opportunities in Non Uniform Sampling
Creators: Mike Chen
Publisher: name: IEEE
Year: 2020

SSCS Webinar Slides
ABSTRACT:
Uniform sampling has been widely adopted in today’s circuit designs, ranging from data converters (ADC and DAC), and discrete-time signal processing (such as switched-capacitor filters). It is a well-developed processing technique that leads to many circuit architectures. However, Nyquist theory does not limit us to processing the samples at a uniform time grid so long as the average sample rate is sufficiently high, i.e., no loss of signal information. Why not sample the analog signal in a non-uniform time grid? What is the benefit by doing so? What is the underlying signal processing implication? In this talk, we will provide a background overview and explore new opportunities in non-uniform sampling (NUS) along with several silicon prototypes (from data converter to RF transceiver) that leverage non-uniform sampling. Thanks to the unique properties of NUS, there are interesting possibilities for future circuit- and system-level architectural innovations.

description: Supergiant fast X-ray transients are a new class of high mass X-ray binaries recently discovered with INTEGRAL. Hours long outbursts from these sources have been observed on numerous occasions at luminosities of ~1E36-1E37 erg/s, whereas their low level activity at ~1E32-1E34 erg/s has not been deeply investigated yet due to the paucity of long pointed observations with high sensitivity X-ray telescopes. Here we report on the first long (~32 ks) pointed XMM-Newton observation of IGR J16479-4514, a member of this new class. This observation was carried out in March 2008, shortly after an outburst from this source, with the main goal of investigating its low level emission and physical mechanisms that drive the source activity. Results from the timing, spectral and spatial analysis of the EPIC-PN XMM-Newton observation show that the X-ray source IGRJ16479-4514 underwent an episode of sudden obscuration, possibly an X-ray eclipse by the supergiant companion. We also found evidence for a soft X-ray extended halo around the source that is most readily interpreted as due to scattering by dust along the line of sight to IGRJ16479-4514. We discuss this result in the context of the gated accretion scenarios that have been proposed to interpret the behaviour of supergiant fast X-ray transient.

Broadband and intense sound transmission loss by a coupled-resonance acoustic metamaterial

Publisher: name: arXiv
Year: 2021
Subjects: subject: Applied Physics (physics.app-ph)

description: The advent of acoustic metamaterials opened up a new frontier in the control of sound transmission. A key limitation, however, is that an acoustic metamaterial based on a single local resonator in the unit cell produces a restricted narrow-band attenuation peak; and when multiple local resonators are used the emerging attenuation peaks -- while numerous -- are each still narrow and separated by pass bands. Here, we present a new acoustic metamaterial concept that yields a sound transmission loss through two antiresonances -- in a single band gap -- that are fully coupled and hence provide a broadband attenuation range; this is in addition to delivering an isolation intensity that exceeds 90 decibels for both peaks. The underlying coupled resonance mechanism is realized in the form of a single-panel, single-material pillared plate structure with internal contiguous holes$-$a practical configuration that lends itself to design adjustments and optimization for a frequency range of interest, down to sub-kilohertz, and to mass fabrication.

SSCS Webinar Slides
ABSTRACT:
In the past year, the outbreak of COVID-19 has affected many lives globally. The suboptimal response to the pandemic revealed systematic deficiencies and gaps in our modern healthcare system. One specific area with consequential shortcomings was the diagnosis of infection and the pathogen, particularly the absence (or delayed deployment) of precision tests where and when needed. In this talk, we will discuss and review highly customized IC technologies, broadly defined, that have the potential to address this unmet need, specifically integrated biosensors and CMOS biochip systems. First, we will review the system-level requirements of molecular diagnostics (MDx) systems and explain how they identify the unique DNA/RNA sequences of the pathogen (e.g., COVID-19 one-hour PCR test) to detect infections while achieving appropriate clinical specificity and selectivity. Next, we will discuss in detail methods by which we can design and implement MDx sensors using IC technologies. We will provide specific examples, tradeoff analysis, and manufacturing options for realizing a true CMOS MDx biochip. At the end, we will list key challenges and potential opportunities in this field.

description: The workshop “The state of the bioeconomy in Colombia, its progress and challenges in four regions within the framework of the Sustainable Development Goals” was held at an ideal time for the future of the bioeconomy in Colombia, a stage in which several paths are emerging in sight, some that are beginning to materialize.The workshop was divided into two main themes, as can be seen in this report. During the morning sessions, governance issues deemed important for the bioeconomy development at national level were discussed. and in the afternoons, sessions were held aimed at investigating the state of the bioeconomy of the four prioritized regions– Antioquia, Coffee Zone, Valle del Cauca, and Orinoquia, The workshop sought to provide some elements that contribute with the process of cementing a bioeconomy vision that truly becomes an agent of change and progress, rather than discussions in academic settings.
Resonant-tunnelling-assisted crossing for subwavelength plasmonic slot waveguides

description: We theoretically investigate the properties of crossing for two perpendicular subwavelength plasmonic slot waveguides. We show that, when encountering nano intersection, the crosstalk for the direct crossing is around 25%, almost same as throughout. In terms of symmetry considerations and resonant-tunnelling effect, we design compact cavity-based structures. Our results show that the crosstalk is eliminated and the throughput reaches the unity on resonance. Simulations results are in agreement with those from the coupled-model theory. When taking into account of the material loss, due to the unchanged symmetry properties of the modes, the crosstalk is still suppressed. Our results may open a way to construct nanoscale crossings for high-density nanoplasmonic integration circuits.

description: Microwave bandpass filters constructed from materials exhibiting some nonlinearity, such as superconductors, will generate intermodulation distortion (IMD) when subjected to signals at more than one frequency. In commercial applications of superconductive receive filters, it is possible for IMD to be generated when a weak receive signal mixes with very strong out-of-band signals, such as those coming from the transmitter. A measurement procedure was developed and data were taken on several different types of superconducting bandpass filters, all developed for commercial application. It was found that in certain interference situations, the 3-tone mixing can produce a spur that is noticeable by the receiver, but that there are simple preventative design solutions.

Slides for Webinar: The Social and Business Value of Smart City Platforms
Smart city platforms allow end users to gain seamless access to data across the multiple siloes of functionality that exist in today’s cities.  These include applications like transportation management, health and public safety, environmental (including water and wastewater), energy, governance, the built environment, and more.  This is particularly relevant today as cities and towns struggle to deal with the economic and social challenges posed by the COVID-19 pandemic with an eye toward long-term resiliency.   This presentation will provide an introduction to smart city platform architecture, functionality, and use cases, and will explore some of the ways that those in the industrial sector can bring their experience to bear in optimizing the performance of today’s cities.

description: While most galaxies appear to host a central supermassive black hole (SMBH), they are expected to also contain a substantial population of off-center "wandering" SMBHs naturally produced by the hierarchical merger-driven process of galaxy assembly. This population has been recently characterized in an analysis of the Romulus cosmological simulations, which correct for the dynamical forces on SMBHs without artificially pinning them to halo centers. Here we predict an array of electromagnetic signatures for these wanderers. The predicted wandering population of SMBHs from Romulus broadly reproduces the observed spatial offsets of a recent sample of hyperluminous X-ray sources. We predict that the sources with the most extreme offsets are likely to arise from SMBHs within satellite galaxies. These simulations also predict a significant population of secondary active galactic nuclei (AGN) with luminosities at least 10\% that of the central AGN. The majority of galaxies at $z=4$ that host a central AGN with bolometric luminosity $L_\mathrm{bol}>10^{42} \ \mathrm{erg} \; \mathrm{s}^{-1}$ are predicted to host a companion off-center AGN of comparable brightness. We demonstrate that stacked X-ray observations of similar mass galaxies may reveal a halo of collective emission attributable to these wanderers. Finally, because wanderers dominate the population of SMBHs with masses of $\lesssim 10^7\,M_{\odot}$ in Romulus, they may dominate tidal disruption event (TDE) rates at these masses if they retain a stellar component (e.g. a nuclear star cluster). This could warrant an order of magnitude correction to current theoretically estimated TDE rates at low SMBH masses.

description: The application of glazing allows the construction of very transparent roofs. To determine a transparent structure the lightness is a measurable factor within the subjective experience of transparency. At the example of transparent space grid structures with axial load-bearing glazing the interaction between measureable transparency, percept transparency and constructive criteria is analyzed. The constructive criteria include different parameters as pre-assembling, stability, member length, knot geometry and joint sealing. The measureable transparency criteria include lightness and transparency values due to contrast investigation and the percept transparency bases on a psychological study of 325 people assessing film sequences of 3D environments.

Contemporary reactions to smallpox inoculation in eighteenth-century France
Creators: name: Davis, Charles Michael
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study is to examine the medical, religious, and social reactions to smallpox inoculation in French society and to analyze the nature of the controversy and the dominant part played in it by the learned community and medical profession of France as it took shape in the general context of the eighteenth century. The approach has stressed those aspects of the social history of medical ideas and practices and of the social history of contemporary thought which seems to make sense of the important discussions over inoculation. Although strictly speaking the controversy over inoculation did not cease at any point in the eighteenth century, the most important discussions took place between 1714 and 1775. Therefore, the present study will not deal with events after 1775 during which time the practice of inoculation became accepted, though not universally established, in France. It is important to note the period under discussion marked a crucial phase in the history of the Enlightenment in France, for the campaign on behalf of inoculation then assumed many of its special characteristics. Certain key developments occurred which provide the framework of this study. The first is concerned with the safety of the methods and development in their techniques during the course of the eighteenth century which helps to explain the motives and timing for the general acceptance of smallpox inoculation. The second deals with the social, religious, and medical responses to inoculation in the early eighteenth century. The fear that partial inoculations of only some members of the community would spread the natural form of the disease to the rest was the principal reason which accounts for the prohibition of the practice during this period. The third deals with three of the most important aspects of the controversy. Firstly, the growing interest of "enlightened" governmental authorities and medical men to extend the practice to the suffering masses as well as the interrelated measures of public health and hygiene; secondly, the tendency to abandon traditional religious and medical values and to substitute for them a new way of thinking based on probabilistic formulations of comparative mortality rates of inoculated and natural smallpox cases; and thirdly, the relatively high price of inoculation and the reluctance of medical personnel to spread inoculation to the French population as a whole.

description: When a human asks questions online, or when a conversational virtual agent asks human questions, questions triggering emotions or with details might more likely to get responses or answers. we explore how to automatically rewrite natural language questions to improve the response rate from people. In particular, a new task of Visual Question Rewriting(VQR) task is introduced to explore how visual information can be used to improve the new questions. A data set containing around 4K bland questions, attractive questions and images triples is collected. We developed some baseline sequence to sequence models and more advanced transformer based models, which take a bland question and a related image as input and output a rewritten question that is expected to be more attractive. Offline experiments and mechanical Turk based evaluations show that it is possible to rewrite bland questions in a more detailed and attractive way to increase the response rate, and images can be helpful.
The Dust Scattering Model Can Not Explain The Shallow X-ray Decay in GRB Afterglows

description: A dust scattering model was recently proposed to explain the shallow X-ray decay (plateau) observed prevalently in Gamma-Ray Burst (GRB) early afterglows. In this model the plateau is the scattered prompt X-ray emission by the dust located close (about 10 to a few hundred pc) to the GRB site. In this paper we carefully investigate the model and find that the scattered emission undergoes strong spectral softening with time, due to the model's essential ingredient that harder X-ray photons have smaller scattering angle thus arrive earlier, while softer photons suffer larger angle scattering and arrive later. The model predicts a significant change, i.e., $Δ\b \sim 2 - 3$, in the X-ray spectral index from the beginning of the plateau toward the end of the plateau, while the observed data shows close to zero softening during the plateau and the plateau-to-normal transition phase. The scattering model predicts a big difference between the harder X-ray light curve and the softer X-ray light curve, i.e., the plateau in harder X-rays ends much earlier than in softer X-rays. This feature is not seen in the data. The large scattering optical depths of the dust required by the model imply strong extinction in optical, $A_V \gtrsim $ 10, which contradicts current findings of $A_V= 0.1 - 0.7$ from optical and X-ray afterglow observations. We conclude that the dust scattering model can not explain the X-ray plateaus.
