Feature Mapping for Learning Fast and Accurate 3D Pose Inference from Synthetic Images (2017)

We propose a simple and efficient method for exploiting synthetic images when training a Deep Network to predict a 3D pose from an image. The ability of using synthetic images for training a Deep Network is extremely valuable as it is easy to create a virtually infinite training set made of such images, while capturing and annotating real images can be very cumbersome. However, synthetic images do not resemble real images exactly, and using them for training can result in suboptimal performance. It was recently shown that for exemplar-based approaches, it is possible to learn a mapping from the exemplar representations of real images to the exemplar representations of synthetic images. In this paper, we show that this approach is more general, and that a network can also be applied after the mapping to infer a 3D pose: At run time, given a real image of the target object, we first compute the features for the image, map them to the feature space of synthetic images, and finally use the resulting features as input to another network which predicts the 3D pose. Since this network can be trained very effectively by using synthetic images, it performs very well in practice, and inference is faster and more accurate than with an exemplar-based approach. We demonstrate our approach on the LINEMOD dataset for 3D object pose estimation from color images, and the NYU dataset for 3D hand pose estimation from depth maps. We show that it allows us to outperform the state-of-the-art on both datasets.
Qualification et génération de vecteurs pour la validation et le test de production de systèmes analogiques, mixtes et RF (2006)

L'augmentation de la complexité des systèmes sur puce mixtes et RF (SoC AMS&RF) rend difficile leur test. En effet, les défauts pouvant apparaître lors de la conception et la fabrication de ces circuits sont de plus en plus difficilement observables et contrôlables. Plusieurs méthodes de test ont déjà été développées pour les composants RF élémentaires mais ces méthodes conduisent à des temps de simulation rédhibitoires pour la génération des tests de SoC AMS&RF. Ainsi, nous proposons une méthode pour la qualification et la génération de vecteurs de test basée sur l'injection et la simulation de fautes au niveau comportemental. Cette approche est validée sur un IC, développé par ST Microelectronics, réalisant le front-end RF d'un système d'émission-réception WCDMA.
Design and Verification of IEEE 802.22 WRAN Physical Layer (2008)

This paper describes the design and verification of IEEE 802.22 WRAN physical layer. The WRAN physical layer is fundamentally based on the IEEE 802.16e system, but the OFDMA parameters including preamble structure and pilot pattern are newly designed by considering the WRAN channel environments. In this paper, we present the simulation models and results by using appropriate synchronization and channel estimation algorithms. From the results of those simulations, we can obtain 90% preamble detection probability at SNR more than -5 dB, and we can synchronize the CPE to the BS within 2 % of sub-carrier spacing at SNR more than about 1 dB. Moreover, by using the LMMSE algorithm to estimate the channel, we can reduce the performance degradation of 0.2~0.5 dB compared to ideal channel estimation. In conclusion, we have found that the proposed receiver meets the functional requirement document (FRD) for WRAN physical layer.

Efficient execution of parallel applications in multiprogrammed multiprocessor systems (1996)

Existing techniques for sharing the processing resources in multiprogrammed sharedmemory multiprocessors, such as time-sharing, space-sharing, and gang-scheduling, typically sacrifice the performance of individual parallel applications to improve overall system utilization. We present a new processor allocation technique that dynamically adjusts the number of processors an application is allowed to use for the execution of each parallel section of code based on the current system load. This approach exploits the maximum parallelism possible for each application without overloading the system. We implement our scheme on a Silicon Graphics Challenge multiprocessor system and evaluate its performance using applications from the Perfect Club benchmark suite and synthetic benchmarks. Our approach shows significant improvements over traditional time-sharing and gang scheduling. It has performance comparable to or slightly better than static space-sharing, but our strategy is more robust sinc...

Aeroelastic Loads and Sensitivity Analysis for Structural Loads Optimization (1999)

An aeroelastic integrated loads subsystem (AILS) is being developed and verified for the calculation of aeroelastic loads for analysis and design. AILS will fit within the aeroelastic design optimization program. The purpose of AILS is to integrate the maneuver and gust loads calculation process with structural analysis and optimization. AILS' active control capabilities and analytical sensitivity analysis will allow a simultaneous optimization of loads, structures, and active load alleviation system with flutter and other aeroelastic constraints. This first version of AILS includes a linear analysis for steady maneuver and unsteady aeroserv oelastic gust loads and their sensitivities to structural design variables and control parameters. AILS static aeroelastic analysis offers 1) full aircraft aeroelastic trim using aircraft angles of attack and sideslip, control-surface deflections, and/or motion rates and accelerations; 2) balanced distributed aeroelastic loads; 3) stress-based critical loads selection; 4) wing jig shape calculations for a specified nominal cruise wing shape and loading; 5) static aeroelastic stability and control derivatives and control effectiveness; and 6) static aeroelastic load sensitivities to structural design variables with constrained or variable nominal cruise shape to be used in optimization. The aeroservoelastic gust load capabilities in AILS include 1) random frequency response analysis for displacement, velocity, acceleration, element force, and stress; 2) flight control and active load alleviation system; 3) calculation of rms and zero-crossing frequency; and 4) analytical derivative of random gust response to control gains. These analyses are compared with MSC/NASTRAN and a proprietary dynamic analysis program (C4EZ). The results of comparisons for the static aeroelastic and gust response analyses of AILS are shown for two commercial transport aircraft: one is a wide-body subsonic transport and the other is a high-speed civil transport configuration at subsonic conditions. The static loads and stability derivatives for two models are compared with MSC/NASTRAN for both aircraft, and gust loads are compared with a production gust-load analysis for the subsonic transport case. In all cases excellent agreement is obtained. Validation of AILS' load sensitivity calculations was done through comparison with the finite difference approach. Excellent agreement was obtained between analytical and numerical derivatives.
The phosphorylation of CapZ-interacting protein (CapZIP) by stress-activated protein kinases triggers its dissociation from CapZ (2005)

A protein expressed in immune cells and muscle was detected in muscle extracts as a substrate for several SAPKs (stress-activated protein kinases). It interacted specifically with the F-actin capping protein CapZ in splenocytes, and was therefore termed 'CapZIP' (CapZ-interacting protein). Human CapZIP was phosphorylated at Ser-179 and Ser-244 by MAPKAP-K2 (mitogen-activated protein kinase-activated protein kinase 2) or MAPKAP-K3 in vitro. Anisomycin induced the phosphorylation of CapZIP at Ser-179 in Jurkat cells, which was prevented by SB 203580, consistent with phosphorylation by MAPKAP-K2 and/or MAPKAP-K3. However, osmotic shock-induced phosphorylation of Ser-179 was unaffected by SB 203580. These and other results suggest that CapZIP is phosphorylated at Ser-179 in cells by MAPKAP-K2/MAPKAP-K3, and at least one other protein kinase. Stress-activated MAP kinase family members phosphorylated human CapZIP at many sites, including Ser-68, Ser-83, Ser-108 and Ser-216. Ser-108 became phosphorylated when Jurkat cells were exposed to osmotic shock, which was unaffected by SB 203580 and/or PD 184352, or in splenocytes from mice that do not express either SAPK3/p38gamma or SAPK4/p38delta. Our results suggest that CapZIP may be phosphorylated by JNK (c-Jun N-terminal kinase), which phosphorylates CapZIP to >5 mol/mol within minutes in vitro. Osmotic shock or anisomycin triggered the dissociation of CapZIP from CapZ in Jurkat cells, suggesting that phosphorylation of CapZIP may regulate the ability of CapZ to remodel actin filament assembly in vivo.
Role of Exercise and Dietary Supplementation in Attenuation of Traumatic Brain Injury in American Football (2019)

Given the prevalence of traumatic brain injuries (TBI) in contact sports such as American Football, the need for increased research in TBI has been dramatically increased over the last 20-years. TBI has two main mechanisms that cause neuronal cell death following an incident: direct axonal death and neuronal inflammation, with the latter being the most common because it persists more than a decade and chronically affects neighboring neurons. Therefore, proper management that reduces inflammation post-TBI should be stressed in order to facilitate propitious recovery. While sideline concussion protocols have been implemented in sports fields, it is important immediately to initiate recovery protocols in order to minimize the degree of progressive neuronal death caused by TBI. While difficult to individualize symptoms for each occurrence, it is essential to incorporate a pretest of cognition, memory, and balance as a means of determining the severity of TBI. Although the sports concussion assessment tool 2 has been used by collegiate and professional teams, this tool is just based on observation and comparison. Thus, more precise and advanced diagnosis using biological methods are needed to accurately assess individual symptoms, which should save lives. One example is to use serum creatine kinase (CK) levels because CK released from damaged brain tissues enters the bloodstream and thus TBI can be quickly assessed and identified. While the immediate diagnosis of TBI is one part of management, efficacious treatments of post-TBI is also critical. Regarding this, exercise and nutritional supplementation have been reported to be effective. While specific pathways of neuroprotective mechanisms remain to be elucidated, endurance exercise along with supplementation of fish oil, caffeine, and vitamin D seems to elicit neuroprotective effects. This review provides potential mechanisms responsible for exercise and nutritional supplementation-mediated neuroprotection against TBI. Since human subjects are limited to mechanistic studies requiring invasive surgical procedures, research involving animals (e.g., mouse and rat) are also introduced in this review.
Time Evolution of Excited States in CdSe Nanocrystals (1994)

Early theoretical work predicted that quantum dots would exhibit discrete, well separated optical excitations, with narrow linewidths, and uncommonly large excited state polarizabilities 1 . This unusual combination could result in some unusual nonlinear properties. Ever since there has been steady progress in the preparation and characterization of nanometer size semiconductor nanocrystals, with CdSe still remaining the prototypical direct band gap material 2 . During the past two years we have undertaken a systematic study of the size dependent photophysics in these materials. Colloidally prepared II-VI nanocrystals embedded in polymers and cooled to low T lend themselves readily to the application of many time and frequency resolved optical characterization techniques 3 . These include absorption, fluorescence, electric field modulation of the absorption and fluorescence, three pulse photon echoes, and resonance Raman scattering.
Non-contact, capacitive biosensor electrodes for electrostatic charge reduction (2013)

Non-contact capacitive sensors are receiving much attention as the desire for long-term portable biological sensing devices grows. However, electrostatic discharge (ESD) generation, arising from the sensor electrodes rubbing against the subjects clothing, is a significant challenge. We propose an actively driven shielding electrode with a grid-multilayer structure. We have considered and compared five electrode prototype designs. The signal-to-ESD noise ratio (SENR) and maximum amplifier noise budget were measured for the purposes of comparing the different electrode designs. The results indicate that the grid electrode has relatively moderate SENR and an acceptable noise design budget better than the other proposed prototypes.
Nedd4 Regulates Egress of Ebola Virus-Like Particles from Host Cells (2003)

Ebola virus budding is mediated by two proline-rich motifs, PPxY and PTAP, within the viral matrix protein VP40. We have previously shown that a Nedd4-like protein BUL1, but not Nedd4, positively regulates budding of type D retrovirus Mason-Pfizer monkey virus (J. Yasuda, E. Hunter, M. Nakao, and H. Shida, EMBO Rep. 3:636-640, 2002). Here, we report that the cellular E3 ubiquitin ligase Nedd4 regulates budding of VP40-induced virus-like particles (VLPs) through interaction with the PPxY motif. Mutation of the active site cysteine (C894A), resulting in abrogation of ubiquitin ligase activity, impaired the function of Nedd4 on budding. In addition, the WW domains of Nedd4 are essential for binding to the viral PPxY motif, and a small fragment of Nedd4 containing only WW domains significantly inhibited Ebola VLP budding in a dominant-negative manner. Our findings suggest that the viruses containing PPxY as an L-domain motif specifically use E3 in the process of virus budding. We also examined the effects of overexpression of Tsg101 and its mutant. As expected, Tsg101 enhanced VP40-induced VLP release, and TsgDeltaC, which lacks its C-terminal half, inhibited VLP release. These results indicate that Nedd4, together with Tsg101, plays an important role in Ebola virus budding.
Keteniminium Salts as Key Intermediates for the Efficient Synthesis of 3‐Amino‐Indoles and ‐Benzofurans (2019)

Abstract Herein, we describe a high yielding approach towards the synthesis of 3‐amino‐indoles and ‐benzofurans through 6 π ‐electrocyclization. This was made possible by taking advantage of the high reactivity of keteniminium salts, formed in‐situ by treating with triflic anhydride and 2‐fluoropyridine amides bearing at the α ‐position either an aniline or a phenoxy moiety. These mild conditions, on top of furnishing rapidly the 3‐aminobenzoheteroles, allow the tolerance of various functional groups. Control experiments were carried out to highlight that the keteniminium is, indeed, in most cases, the reactive intermediate and conformational preferences of such species were investigated through a DFT study.
Formation of High Quality Silicon Nitride Films using Microwave Excitation Plasma (2007)

The electric characteristics Si3N4 films the interface characteristics of Si3N4/Si formed by newly developed microwave-excited high-density plasma are described. The leakage current through the Si3N4 films reduces 3 orders of magnitude and the lifetime improves 30,000 times compared to the conventional SiO2 films formed by a thermal oxidation. The MISFET on Si(100) surface with gate insulator of Si3N4 films have more excellent performance compared to that with conventional SiO2 films. The crystal orientation of silicon wafer surface is affected to the subnitride at Si3N4/Si interface. The subnitride at Si3N4/Si decreases with an increase in Si atom density in the silicon wafer surface, as a result, the quantity of subnitride is lowest in Si(110) surface than any other surfaces. The valence band offset at Si3N4/Si interface is independent of a silicon wafer surface. Si3N4 films formed by the microwave excited plasma is essential to high performance and low leakage LSI devices.
Dispersion effects in four-wave mixing measurements of ions in solids (1990)

We have performed nondegenerate four-wave mixing measurements on Cr(3+) ions in three crystals: BeAl(2)O(4), Gd(3)Sc(2)Ga(3)O(12), and LaMgAl(11)O(19). Two laser beams of the same frequency were used to resonantly pump one of the absorption bands of Cr(3+), and probe beams with three different wavelengths ranging from 442 to 1064 nm were used to generate a signal from the laser-induced population grating. The observed four-wave mixing signal strength was found to increase as the wavelength of the probe beam was decreased. A model was utilized to explain these results based on the change in polarizability of the Cr(3+) ions when they are in the metastable state versus the ground state, and it was found that the dispersion effects can be described by a single-oscillator model with the lowest-energy charge-transfer transition of Cr(3+) making the dominant contribution to the signal.
Interference mitigation techniques for clustered multicell joint decoding systems (2011)

Multicell joint processing has originated from information-theoretic principles as a means of reaching the fundamental capacity limits of cellular networks. However, global multicell joint decoding is highly complex and in practice clusters of cooperating Base Stations constitute a more realistic scenario. In this direction, the mitigation of intercluster interference rises as a critical factor towards achieving the promised throughput gains. In this paper, two intercluster interference mitigation techniques are investigated and compared, namely interference alignment and resource division multiple access. The cases of global multicell joint processing and cochannel interference allowance are also considered as an upper and lower bound to the interference alignment scheme, respectively. Each case is modelled and analyzed using the per-cell ergodic sum-rate throughput as a figure of merit. In this process, the asymptotic eigenvalue distribution of the channel covariance matrices is analytically derived based on free-probabilistic arguments in order to quantify the sum-rate throughput. Using numerical results, it is established that resource division multiple access is preferable for dense cellular systems, while cochannel interference allowance is advantageous for highly sparse cellular systems. Interference alignment provides superior performance for average to sparse cellular systems on the expense of higher complexity.
Optical waveguides and switches based on periodic arrays of carbon nanotubes (2011)

This document presents the modeling and characterization of novel optical devices based on periodic arrays of multiwalled carbon nanotubes. Vertically aligned carbon nanotubes can be grown in the arrangement of two-dimensional arrays of precisely determined dimensions. Having their dimensions comparable to the wavelength of light makes carbon nanotubes good candidates for utilization in nano-scale optical devices. We report that highly dense periodic arrays of multiwalled carbon nanotubes can be utilized as sub-wavelength structures for establishing advanced optical materials, such as metamaterials and photonic crystals. We demonstrate that when carbon nanotubes are grown close together at spacing of the order of few hundred nanometers, they display artificial optical properties towards the incident light, acting as metamaterials. By utilizing these properties we have established micro-scaled plasmonic high pass filter which operates in the optical domain. Highly dense arrays of multiwalled also offer a periodic dielectric constant to the incident light and display interesting photonic band gaps, which are frequency domains within which on wave propagation can take place. We have utilized these band gaps displayed by a periodic nanotube array, having 400 nm spacing, to construct photonic crystals based optical waveguides and switches.
Passively modelocked electrically pumped VECSELs (2013)

In modelocked electrically pumped VECSELs (EP-VECSELs) the gain saturation strongly influences the pulse formation. Here we present a detailed gain characterization of EP-VECSELs as published the first time in [1]. The spectral gain-distribution and the gain saturation behavior of two devices with different field-enhancement in the quantum-well gain layers are investigated. Comparing spectral bandwidth, small-signal gain and saturation fluence of the three devices, we chose the most suitable for modelocking experiments. Using a low-saturation fluence SESAM we have generated 9.5-ps-pulses with an average output-power of 7.6 mW at 1.4 GHz repetition-rate, which have been the shortest pulses from an EP-VECSEL to date [1].
Threshold Energy Switching and Its Application to Wireless Sensing in High Energy Manufacturing Processes (2002)

A solid state threshold energy switching device based on a relaxation oscillator is discussed in the context of a self energizing wireless pressure sensor. The study is an integral part of the design of a wireless pressure sensor for in-situ injection molding machine cavity pressure measurement and real time process control. The pressure information is measured using a piezoelectric stack and converted to a train of ultrasonic pulses, using the oscillator based threshold switching device, to a receiver outside of the mold. In this paper the threshold switching device is developed, simulated using a circuit simulation program, and validated experimentally. Its properties are discussed with reference to pressure measurement and acoustic signal transmission.
Comparative Study of the Coupling between Topoisomerase I Activity and High-Mobility Group Proteins in E. coli and Mammalian Cells (2000)

It is now well established that the HMG box DNA-binding motif can alter the topology of double-stranded DNA in several ways. Using the spermatid-specific tsHMG as a model protein of the HMG-1/-2 family, we have demonstrated that its expression in E. coli produces an increase in plasmid supercoiling density that is likely a consequence of its ability to constrain free supercoils in vivo. As demonstrated in vitro, stabilization of free DNA supercoils by tsHMG prevents topoisomerase I from gaining access to the template and could represent a mechanism for the apparent inhibition of topoisomerase I in bacteria. A similar modulation of eukaryotic topoisomerase I activity was not detected after expression of the tsHMG in mammalian cells. This differential response is discussed in terms of the marked difference in DNA packaging and accessibility of free supercoils in prokaryotic vs. eukaryotic cells.
