Reducing Test Cost of Infrared Detectors: A Machine Learning Approach to Failure Prediction of Infrared Detectors (2018)

It is important to ensure the infrared detectors will work properly in practical application, so a series of tests must be carried out before putting them into application. In order to reduce test cost, this paper proposed a two-stage failure prediction model for infrared detectors during tests based on the logistic regression model. The solution has shown significant business values. With only the first three test stagesâ€™ data, under the condition that 99% of the normal detectors are classified as normal products, we can screen out 54.55% of the detectors which will fail before the last vacuum test. Furthermore, in the second stage prediction, we can screen out 80% of the final failure detectors.
Controlling the device field edge to achieve a low power TFSOI technology (2002)

The impact of stress and dopant redistribution along the field edge of SOI devices on offstate leakage, low voltage performance, and yield is discussed. For the first time, stress caused by overoxidation of the field region is shown to cause excessive device leakage and yield loss. A modified PBL isolation scheme is used to minimize this effect. Dopant redistribution is known to cause field edge leakage and is shown to contribute to narrow channel effects. A novel integration scheme is described to reduce the impact of dopant redistribution and result in a TFSOI technology suitable for low power applications.
Effect of Hydrogen Gas on c-Axis Oriented AlN Films Prepared by Reactive Magnetron Sputtering (1981)

AlN films were deposited on glass substrates by reactive dc magnetron sputtering in an atmosphere of pure nitrogen gas or a mixed gas of hydrogen and nitrogen. The AlN films deposited in the nitrogen gas had a c -axis perpendicular to the substrate surface. On the other hand, the film deposited in the gas with hydrogen added showed a c -axis parallel to the substrate surface. Optical transmittance of the parallel oriented films was better than that of the perpendicularly oriented films and there was a great difference in the microstructure of the film surface between these two films.
Ileus and Obstruction in the Surgical Critical Care Patient (2017)

Gastrointestinal dysfunction is a common occurrence in the critically ill surgical patient as both a contributor to disease progression and a consequence of critical illness. Failure of motility may ultimately progress to obstruction, either functional (e.g., paralytic ileus) or mechanical (e.g., small bowel obstruction). Obstruction leads to bowel distention, fluid sequestration in the lumen and wall of the bowel, alterations in mucosal integrity, and bacterial overgrowth, which results in not only local bowel ischemia but also distant organ damage due to the release of inflammatory cytokines. Although postoperative ileus is a common condition, in the critically ill patient, it may signify a serious complication such as anastomotic leak or sepsis; therefore, management is directed toward identification and treatment of the underlying cause. Regarding small bowel obstruction (SBO), management hinges on whether or not the bowel is strangulated, and the need for operation should be addressed at every step of the evaluation. Although most patients are successfully treated without operation, SBO is a surgical disease, a fact underscored by the improved outcomes seen in patients admitted to a surgical service. Large bowel obstruction is a surgical emergency that requires prompt decompression either by colonoscopy or surgery. Regardless of the etiology of gastrointestinal dysfunction, emergency surgery is required in patients with signs of bowel strangulation or perforation such as tachycardia, peritonitis, fever, or leukocytosis. Key words: acute colonic pseudo-obstruction, adhesive small bowel disease, ileus, large bowel obstruction, Ogilvie syndrome, small bowel obstruction bowel perforation, volvulus

A channel access protocol for tactical IP networks using software defined VHF radios (2003)

Military ad-hoc wireless networks are becoming increasingly common in today's world. Military networks have requirements for security, jamming and spoofing resistance, voice transmissions, and range that are often not feasible to achieve with off-the-shelf commercial products. These networks may also require multiple users to share a variety of services such as file transfer, e-mail, situational awareness reports, and voice over a single channel. Performance is often limited by the number of devices and interfaces at each station. With software-defined radios that incorporate unprecedented digital signal processing power, coupled with industry standard interfaces such as the Internet protocol (IP), the radio chassis can literally become a "system in a box". Channel access protocols can also benefit greatly from being integrated with the radio modem. The RF Communications Division of Harris Corporation has developed a black-side (post-encryption) channel access protocol based on the well-known MACA protocol. This protocol performs well on real-world networks facing such challenges as voice priority over data, "hidden nodes", and varying channel conditions. Wireless IP networking capability based on this protocol has been implemented and fielded in Harris's software-defined Falcon II Tactical Radios. This paper discusses the benefits/tradeoffs of embedded black-side channel access protocols and presents test results from a typical military communication system based on the Harris RF-5800V-MP radio.
TO LIVE OR DIE: A LOOK AT ELDERLY SUICIDE (1993)

Trace Minerals in Human Hair by Atomic Absorption Spectrophotometry—Recovery Study (1975)

Abstract Satisfactory recovery studies of thirteen trace elements, Na, K, Ca, Mg, Zn, Cu, Fe, Mn, Co, Pb, Li, Cd and Cr in human scalpal hair was obtained. There is little or no interference in the analysis of these elements in hair matrix by atomic absorption spectrophotometry using the wet nitric and perchloric acid digestion method. Methods to remove surface contamination in hair were also discussed.
Reduction of out of band radiation using carrier-by-carrier partial response signalling in orthogonal frequency division multiplexing (2010)

Orthogonal frequency division multiplexing (OFDM) is a mature and one of the most popular multicarrier modulation (MCM) techniques. Also, it is the main candidate for physical layer of cognitive radio (CR) networks. CR is a new method to satisfy ubiquitous demand for wireless services while there is no enough unlicensed spectrum. However, the most important shortcoming of OFDM-based CR systems is the high level of out of band (OOB) components that originate from simple fast Fourier transform (FFT)-based implementation. In this study, the authors propose a novel method to reduce side-lobes of OFDM spectrum. In this method proper carrier-by-carrier partial response signaling is used on the modulated symbols across the time. This method will allow for using other techniques for OOB radiation or peak-to-average power ratio (PAPR) reduction, while does not require high complexity at the transmitter, i.e. just the receiver should have either maximum likelihood sequence detector (MLSD) in case of no pre-coding or a simple slicer in case of pre-coding. Moreover, it will not affect the PAPR but will increase word error rate (WER). Simulation results show that about 7 dB reduction in OOB components can be expected by this method.
Action Recognition With Spatial-Temporal Discriminative Filter Banks (2019)

Action recognition has seen a dramatic performance improvement in the last few years. Most of the current state-of-the-art literature either aims at improving performance through changes to the backbone CNN network, or exploring different trade-offs between computational efficiency and performance, again through altering the backbone network. However, almost all of these works maintain the same last layers of the network, which simply consist of a global average pooling followed by a fully connected layer. In this work we focus on how to improve the representation capacity of the network, but rather than altering the backbone, we focus on improving the last layers of the network, where changes have low impact in terms of computational cost. In particular, we hypothesize that current architectures have poor sensitivity to finer details and we exploit recent advances in the fine-grained recognition literature to improve our model in this aspect. With the proposed approach, we obtain state-of-the-art performance on Kinetics-400 and Something-Something-V1, the two major large-scale action recognition benchmarks.
Differences between fluctuations in heart beat in daily life and under exercise test. (1988)

Multilayer effects in liquid adsorption chromatography with mixed mobile phases (1984)

Abstract This paper describes the theory of liquid adsorption chromatography (LSC) with mixed mobile phase, involving formation of multilayer surface phases. An equation describing the dependence of the capacity ratio upon the mobile phase composition is derived and theoretical curves illustrating the same dependence are calculated accordingly by assuming different thicknesses of the surface phase.
On multiresolution image restoration (2002)

This paper argues that the correct way to use a multiresolution approach to image restoration is to coarsen the posterior distribution of the image via the renormalization group transformation (RGT). It summarises the main results on RGT and points out the difficulties with it. It proposes an alternative transformation which does not have the full properties of the RGT but which preserves the global minimum of the cost function. The major contribution of the paper is to prove some theoretical properties of this transformation which show its significance and usefulness to image processing.
Data Analysis Techniques for Fan Performance in Highly-Distorted Flows from Boundary Layer Ingesting Inlets (2018)

The design of a unique distortion-tolerant fan for a high-bypass ratio boundary-layer ingesting propulsion system has been completed and a rig constructed and tested in the NASA Glenn 8’x6’ wind tunnel. Processing the data from the experiment presented some interesting challenges because of the complexity of the experimental setup and the flow through the test rig. The experiment was run in three phases, each of which employed a unique complement of inlet throat and fan face instrumentation to avoid the blockage that would have resulted from simultaneously installing all of the rakes. The measurement from the individual test points were subsequently combined to compute the overall stage performance. A CFD model of the experiment was used to gain understanding of the flow field and to test some of the techniques proposed for interpolating and extrapolating the measurements into regions where measurements were not made. This capability became extremely useful when it was discovered that there was an unexpected total temperature distortion in the tunnel. The CFD model was modified by inserting a total temperature profile at the upstream boundary that mimicked the measured distortion where measurements were available and that CFD solution was used to investigate methods to infer the complete total temperature field at the fan face.
Seamless Translation of Optical Fiber PolMux-OFDM into a 2×2 MIMO Wireless Transmission Enabled by Digital Training-Based Fiber-Wireless Channel Estimation (2011)

We propose and demonstrate a 2 × 2 multiple-input multiple-output (MIMO) wireless over fiber transmission system. Seamless translation of two orthogonal frequency division multiplexing (OFDM) signals on dual optical polarization states into wireless MIMO transmission at 795.5 Mbit/s net data rate is enabled by using digital training-based channel estimation. A net spectral efficiency of 2.55 bit/s/Hz is achieved.
Adaptive Myriad Filter for Improved Gas Turbine Condition Monitoring Using Transient Data (2004)

The removal of noise and outliers from measurement signals is a major problem in jet engine health monitoring. In this study, we look at the myriad filter as a substitute for the moving average filter which is widely used in the gas turbine industry. The three ideal test signals used in this study are the step signal which simulates a single fault in gas turbine, while ramp and quadratic signals simulate long term deterioration. Results show that the myriad filter performs better in noise reduction and outlier removal when compared to the moving average filter. Further, an adaptive weighted myriad filter algorithm that adapts to the quality of incoming data is studied. The filters are demonstrated on simulated clean and deteriorated engine data obtained from an acceleration process from idle to maximum thrust condition. This data was obtained from published literature and was simulated using a transient performance prediction code. The deteriorated engine had single component faults in the low pressure turbine and intermediate pressure compressor. The signals are obtained from T2 (IPC total outlet temperature) and T6 (LPT total outlet temperature) engine sensors with their non-repeatability values which were used as noise levels. The weighted myriad filter shows even greater noise reduction and outlier removal when compared to the sample myriad and FIR filter in the gas turbine diagnosis. Adaptive filters such as those considered in this study are also useful for online health monitoring as they can adapt to changes in quality of incoming data.
Evaluation of the NCCLS Extended-Spectrum β-Lactamase Confirmation Methods forEscherichia coliwith Isolates Collected during Project ICARE (2003)

To determine whether confirmatory tests for extended-spectrum beta-lactamase (ESBL) production in Escherichia coli are necessary, we selected 131 E. coli isolates that met the National Committee for Clinical Laboratory Standards (NCCLS) screening criteria for potential ESBL production from the Project ICARE (Intensive Care Antimicrobial Resistance Epidemiology) strain collection. For all 131 isolates, the broth microdilution (BMD) MIC of at least one extended-spectrum cephalosporin was >/=2 micro g/ml. For 21 of 131 (16%) isolates, the ESBL confirmatory test was positive; i.e., the BMD MICs of ceftazidime or cefotaxime decreased by >/=3 doubling dilutions in the presence of clavulanic acid (CA) or the disk diffusion zone diameters increased by >/=5 mm around ceftazidime or cefotaxime disks in the presence of CA. All 21 isolates were shown by PCR to contain at least one of the genes bla(TEM), bla(SHV), and bla(OXA), and in isoelectric focusing (IEF) tests, all isolates demonstrated at least one beta-lactamase band consistent with a TEM, SHV, or OXA enzyme. Of the 21 isolates, 3 showed a CA effect for cefotaxime by BMD but not by disk diffusion testing. A total of 59 (45%) of the 131 isolates demonstrated decreased susceptibility to cefpodoxime alone (MIC = 2 to 4 micro g/ml), and none had a positive ESBL confirmatory test result. These were classified as false positives according to ESBL screen test results. For the remaining 51 (39%) isolates, the cefpodoxime MICs ranged from 16 to >128 micro g/ml and the MICs for the other extended-spectrum cephalosporins were highly variable. All 51 isolates gave negative ESBL confirmatory test results. Most showed IEF profiles consistent with production of both a TEM and an AmpC beta-lactamase, and representative isolates of several phenotypic groups showed changes in porin profiles; these 51 isolates were considered true negatives. In all, only 16% of 131 E. coli isolates identified as potential ESBL producers by the current NCCLS screening criteria were confirmed as ESBL producers. Thus, changing the interpretation of extended-spectrum cephalosporins and aztreonam results from the susceptible to the resistant category without confirming the presence of an ESBL phenotype would lead to a large percentage of false resistance results and is not recommended. However, by increasing the cefpodoxime MIC screening breakpoint to >/=8 micro g/ml, 45% of the false-positive results could be eliminated. NCCLS has incorporated this change in the cefpodoxime screening breakpoint in its recent documents.
A vertical submicron polysilicon thin-film transistor using a low temperature process (1994)

This letter presents a submicron (0.5 μ) vertical N-channel MOS thin-film transistor (TFT) fabricated in Polycrystalline Si using a simple low temperature process (/spl les/600/spl deg/C). The channel length is determined by the thickness of an SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> film. As a result, submicron vertical polysilicon TFT's can be fabricated without submicron lithographic equipment that is not yet available for large area active matrix liquid crystal display (AMLCD) applications. The device has a dynamic range of greater than five orders of magnitude after hydrogenation.

Knowledge transfer in ecologically grounded approaches to ubimus: InMesh 1.0 (2019)

We approach the analysis of the dynamics of knowledge transfer and decision-making in ecologically grounded creative practice through a longitudinal study of the exchange processes involved in the elaboration of the installation InMesh 1.0. The paper outlines a theoretical framework for the analysis of knowledge transfer mechanisms in ubiquitous music projects. We focus on a domain-specific practice but rely on concepts that are also applicable to other contexts. We also describe a set of support strategies that enable remote exchanges for group-based aesthetic decision-making. Finally, we document and discuss the development of InMesh 1.0.
Bactericidal activity of β-lactams and amikacin against Haemophilus influenzae: effect on endotoxin release (1992)

Ampicillin or cefotaxime, alone or in combination with amikacin, were tested at levels achievable in CSF for bactericidal activity against eight clinical isolates of Haemophilus influenzae serotype b. Endotoxin release was determined by the limulus amoebocyte lysate test and by macrophage tumour necrosis factor production for each beta-lactam antibiotic, alone and in combination with amikacin. Accelerated killing was observed when amikacin was added to ampicillin or cefotaxime; however, the additional antibiotic-induced bacterial lysis observed after the addition of amikacin to beta-lactam antibiotics was not associated with an increase in endotoxin release.

The Potato virus Y M S N R NIb‐replicase is the elicitor of a veinal necrosis‐hypersensitive response in root knot nematode resistant tobacco (2002)

Summary A root knot nematode resistance gene in Nicotiana tabacum, Rk, providing resistance to the nematode parasite Meloidogyne incognita is tightly linked to, or is a pleiotropic gene with a veinal necrosis systemic hypersensitive response to infection by Potato virus Y (PVY) M(s)N(r). The single PVY M(s)N(r) open reading frame was sequenced and found to have 89% protein identity to PVY N. Individual PVY M(s)N(r) polypeptides were deduced and the corresponding cDNA were cloned into a Potato virus X (PVX) based expression vector and used as templates for in vitro transcriptions. Infected plant sap, from N. benthamiana inoculated with infectious RNA, was used to inoculate both root knot nematode (RKN) resistant and susceptible tobacco lines. Lines were then evaluated for the induction of the hypersensitive response. The PVY M(s)N(r) NIb-replicase protein was found to induce a hypersensitive response 10 days post inoculation in nematode resistant tobacco. None of the other PVX/PVY M(s)N(r) constructs induced a hypersensitive response. The NIb-replicase of PVY N, which shares 93% identity to PVY M(s)N(r), did not induce a hypersensitive response when expressed from the PVX vector. This confirmed that the PVY M(s)N(r) NIb-replicase is the elicitor of PVY M(s)N(r) veinal necrosis on RKN plants and thus the first report of a Potyvirus replicase functioning as an avirulence factor.
