Poly(arylene ether ether nitrile)s containing flexible alkylsulfonated side chains for polymer electrolyte membranes (2013)

ABSTRACT A series of poly(arylene ether ether nitrile)s with different chain lengths of the alkylsulfonates (SPAEEN‐ x : x refers number of the methylene units) are successfully synthesized for fuel cell applications. The polymers produced flexible and transparent membranes by solvent casting. The resulting membranes display a high thermal stability, oxidative stability, and higher proton conductivity than that of Nafion 117 at 80 °C and 95% relative humidity (RH). Furthermore, the SPAEEN‐12 with the longest alkylsulfonated side chain exhibits a higher proton conductivity at 30% RH than that of SPAEEN‐6 despite the lower IEC value, which indicates that the introduction of longer alkylsufonated side chains to the polymer main chain induces an efficient proton conduction by the formation of a well‐developed phase‐separated morphology. © 2013 Wiley Periodicals, Inc.

Anderson’s Theorem for Correlated Insulating States in Twisted Bilayer Graphene (2023)

The emergence of correlated insulating phases in magic-angle twisted bilayer graphene exhibits strong sample dependence. Here, we derive an Anderson theorem governing the robustness against disorder of the Kramers intervalley coherent (K-IVC) state, a prime candidate for describing the correlated insulators at even fillings of the moiré flat bands. We find that the K-IVC gap is robust against local perturbations, which are odd under PT, where P and T denote particle-hole conjugation and time reversal, respectively. In contrast, PT-even perturbations will in general induce subgap states and reduce or even eliminate the gap. We use this result to classify the stability of the K-IVC state against various experimentally relevant perturbations. The existence of an Anderson theorem singles out the K-IVC state from other possible insulating ground states.
Pulsed CO_2-laser heterodyne radar for simultaneous measurements of range and velocity (1984)

A CO2-laser heterodyne system consisting of a CO2 TEA laser transmitter and a CO2 cw laser local oscillator with a fast data system is used to measure simultaneously range and velocity of solid targets. The basic properties of such a system and the accuracies for range measurements were investigated. Further, heterodyne experiments without oscillation of the pulses but with the full advantages of heterodyne detection were carried out.
Mobile Biofeedback Therapy for the Treatment of Panic Attacks: A Pilot Feasibility Study (2019)

Panic attacks are an impairing mental health problem that affects 11% of adults every year. Those who suffer from panic attacks often do not seek psychological treatment, citing the inability to receive care during their attacks as a contributing factor. Herein, we introduce a mobile health (mHealth) biofeedback system that enables treatment of panic attacks wherever and whenever they occur and describe the results of an initial feasibility study. We find that only three of nine chronic panic attack sufferers experienced a panic attack during the study, potentially suggesting a preventative placebo effect common to similar pharmacological interventions. Of the four panic attacks observed, subjects noted that the act of using their phone to record their physiology during the attack helped to stop the attack. While preliminary, these results point toward the need for future development of this mHealth system and a future clinical study to assess its efficacy for preventing panic attacks.
Plasmonics - Towards Subwavelength Optical Devices (2005)

Aspects of the optical properties of metallic nanostructures sustaining surface plasmon-polaritons are reviewed, focusing on differences with dielectric counterparts for the creation of functional nanoscale optical devices such as waveguides and resonators. The ability of plasmonic structures to confine light to volumes significantly smaller than the diffraction limit of light is discussed and a number of important applications are presented, with an emphasis on structures consisting of metallic nanoparticles. The important challenge of efficient excitation of surface plasmon-polaritons in a micro-optic framework is also addressed. A unified description of both plasmonic and dielectric photonic structures using quality factor and effective mode volume as figures of merit should allow for a clear choice of materials system for microand nano-optic devices.
Dioptric defocus maps across the visual field for different indoor environments (2017)

One of the factors proposed to regulate the eye growth is the error signal derived from the defocus in the retina and actually, this might arise from defocus not only in the fovea but the whole visual field. Therefore, myopia could be better predicted by spatio-temporally mapping the 'environmental defocus' over the visual field. At present, no devices are available that could provide this information. A 'Kinect sensor v1' camera (Microsoft Corp.) and a portable eye tracker were used for developing a system for quantifying 'indoor defocus error signals' across the central 58° of the visual field. Dioptric differences relative to the fovea (assumed to be in focus) were recorded over the visual field and 'defocus maps' were generated for various scenes and tasks.
A robust algebraic method for human face recognition (2003)

The feature image and projective image are first proposed to describe the human face, and a new method for human face recognition in which projective images are used for classification is presented. The projective coordinates of projective image on feature images are used as the feature vectors which represent the inherent attributes of human faces. Finally, the feature extraction method of human face images is derived and a hierarchical distance classifier for human face recognition is constructed. The experiments have shown that the recognition method based on the coordinate feature vector is a powerful method for recognizing human face images, and recognition accuracies of 100 percent are obtained for all 64 facial images in eight classes of human faces.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Experimental and theoretical investigation of a volume-Bragg-grating-locked Yb:KYW laser at selected wavelengths (2008)

Laser action is demonstrated in Yb:KYW at wavelengths of 990 nm, 997 nm and 1066 nm, when pumped at 980 nm by a Ti:sapphire laser, with a lowest laser quantum defect of 1.0%. The laser output powers at the various wavelengths were 70mW, 160mW and 140mW, respectively. Locking of the laser wavelength and the spectrally close spacing of pump and laser were achieved by the use of a volume Bragg grating as an input coupler. A theoretical model is also presented that accurately describes the laser at various wavelengths, by solving the laser rate equations at spatial points throughout the laser crystal.
An upper limb robot model of children limb for cerebral palsy neurorehabilitation (2012)

Robot therapy has emerged in the last few decades as a tool to help patients with neurological injuries relearn motor tasks and improve their quality of life. The main goal of this study was to develop a simple model of the human arm for children affected with cerebral palsy (CP). The Simulink based model presented here shows a comparison for children with and without disabilities (ages 6-15) with normal and reduced range of motion in the upper limb. The model incorporates kinematic and dynamic considerations required for activities of daily living. The simulation was conducted using Matlab/Simulink and will eventually be integrated with a robotic counterpart to develop a physical robot that will provide assistance in activities of daily life (ADLs) to children with CP while also aiming to improve motor recovery.
Biogenesis and transmembrane orientation of the cellular isoform of the scrapie prion protein [published errratum appears in Mol Cell Biol 1987 May;7(5):2035] (1987)

Considerable evidence suggests that the scrapie prion protein (PrP) is a component of the infectious particle. We studied the biogenesis and transmembrane orientation of an integral-membrane form of PrP in a cell-free transcription-linked translation-coupled translocation system programmed with a full-length PrP cDNA cloned behind the SP6 promoter. Translation of SP6 transcripts of the cDNA or of native mRNA from either normal or infected hamster brain in the absence of dog pancreas membranes resulted in the synthesis of a single PrP immunoreactive polypeptide (each polypeptide was the same size; Mr, 28,000), as predicted from the known sequence of the coding region. In the cotranslational presence of membranes, two additional forms were observed. Using peptide antisera specific to sequences from the amino- or the carboxy-terminal domain of PrP together with proteinase K or endoglycosidase H digestion or both, we showed that one of these forms included an integrated and glycosylated form of PrP (Mr = 33,000) which spans the bilayer twice, with domains of both the amino and carboxy termini in the extracytoplasmic space. By these criteria, the other form appeared to be an unglycosylated intermediate of similar transmembrane orientation. The PrP cell-free translation products did not display resistance to proteinase K digestion in the presence of nondenaturing detergents. These results suggest that the PrP cell-free translation products most closely resemble the normal cellular isoform of the protein, since its homolog from infected brain was proteinase K resistant. The implications of these findings for PrP structure and function are discussed.

The potential of fiber-depleted starch concentrate produced through air currents assisted particle separation of barley flour in bio-ethanol production (2020)

Isolation of fiber concentrate enriched in β-glucan from barley flour via air currents assisted particle separation (ACAPS) generates an underutilized by-product stream, starch concentrate. Since barley starch concentrate (BSC) is depleted in soluble fibre, we examined the enzyme requirements for its hydrolysis and subsequent fermentation. Lower doses of a common raw starch hydrolyzing enzyme (STARGEN™ 002) effectively hydrolyzed BSC, achieving similar hydrolysis kinetics to the wheat benchmark. Hydrolysis of BSC did not require further enzyme supplementation, which is required for optimal wheat hydrolysis. This likely resulted from the smaller particle size of BSC relative to wheat feedstocks. Interestingly, simultaneous saccharification and fermentation of BSC using a 0.25X dose of STARGEN™ 002 alone enabled efficient ethanol production, though a requirement for phosphorus supplementation was identified. This study proposes a biorefining strategy that supports the generation of a value-added co-product, starch concentrate, while significantly reducing the enzyme requirements for bioethanol production.

[Role of renin profile and age in the choice of the therapeutic approach of arterial hypertension (author's transl)]. (1981)

A group of 116 patients with grade I-II (W.H.O.) essential hypertension was studied. A diuretic treatment was instituted as a first step of therapy in 50 patients while the remaining 66 were firstly treated with beta-blockers. After 6 weeks of treatment the drugs were combined in those patients who did not achieve blood pressure control; this combination therapy was again maintained for 6 weeks and, if necessary, a vasodilating agent was added thereafter. The results show that with diuretic treatment alone diastolic blood pressure was brought to normal values (less than 95 mmHg) in 3/4 of our low renin patients, in 2/3 of normal renin and in 1/3 of high renin hypertensives. On the contrary among the group of patients treated with a beta-blocker alone more than half of the high and normal renin patients were controlled whereas this goal was achieved in only 1/4 of the low renin patients. Similar behaviour was observed subdividing the subjects in young (less than 35 yrs), middle-aged (36-49 yrs) and older (greater than 50 yrs) patients. In conclusion our data indicate that age must be taken into account in classifying hypertensive patients in renin subgroups. In addition if a renin-sodium profile is available, it can be useful in choosing between diuretics or beta-blocker as a first step treatment. Alternatively, younger patients are more likely to have better hypotensive responses with beta-blockers whereas in older patients antihypertensive treatment should preferentially be started with diuretics alone.
Folding tilt rotor demonstrator feasibility study (1986)

This study considers the modification of existing aircraft to the folding tilt rotor (FTR) design configuration, and then addresses the vehicle design requirements necessary to demonstrate the FTR concept throughout the hover/transition high-speed envelope. Three potential candidates are considered: (1) the Bell/Boeing V-22 Osprey combined with either the existing TF-34 convertible engine or a conceptual convertible engine utilizing the torque-converter-coupled fan configuration; (2) a combination of the same powerplants with a modified Lockheed S-3A Viking; and (3) the NASA/Army/BELL XV-15 airframe mated with a conceptual generic turbofan engine with a fixed-pitch fan coupled to the engine by means of a torque converter. Required aircraft modifications are identified and recommended R&D efforts for engine/rotor/airframe integration are presented.
Differential expression analysis of multifactor RNA-Seq experiments with respect to biological variation (2012)

A flexible statistical framework is developed for the analysis of read counts from RNA-Seq gene expression studies. It provides the ability to analyse complex experiments involving multiple treatment conditions and blocking variables while still taking full account of biological variation. Biological variation between RNA samples is estimated separately from the technical variation associated with sequencing technologies. Novel empirical Bayes methods allow each gene to have its own specific variability, even when there are relatively few biological replicates from which to estimate such variability. The pipeline is implemented in the edgeR package of the Bioconductor project. A case study analysis of carcinoma data demonstrates the ability of generalized linear model methods (GLMs) to detect differential expression in a paired design, and even to detect tumour-specific expression changes. The case study demonstrates the need to allow for gene-specific variability, rather than assuming a common dispersion across genes or a fixed relationship between abundance and variability. Genewise dispersions de-prioritize genes with inconsistent results and allow the main analysis to focus on changes that are consistent between biological replicates. Parallel computational approaches are developed to make non-linear model fitting faster and more reliable, making the application of GLMs to genomic data more convenient and practical. Simulations demonstrate the ability of adjusted profile likelihood estimators to return accurate estimators of biological variability in complex situations. When variation is gene-specific, empirical Bayes estimators provide an advantageous compromise between the extremes of assuming common dispersion or separate genewise dispersion. The methods developed here can also be applied to count data arising from DNA-Seq applications, including ChIP-Seq for epigenetic marks and DNA methylation analyses.

Adaptive Time-Frequency Synthesis for Waveform Discernment in Wireless Communications (2021)

The discernment of waveforms for the purpose of identifying the underlying wireless technologies and validating if observed transmissions are legitimate or not remains a challenge within the communications sector and beyond. Conventional techniques struggle to robustly process Signals under Test (SuTs) in real-time. A particular difficulty relates to the selection of an appropriate window size for the processed data when pertinent contextual information on SuTs is not known a priori. The disadvantage of applying a predetermined fixed window size is that of length and shape (i.e., coarse resolution). In contrast, an adaptive window size offers more optimally tuned resolution. Towards this end, we propose a novel approach that uses an Adaptive Resolution Transform (ART) to either maintain a constant (prespecified) resolution, via a Variable Window Size and Shape (VWSS), or adjust the resolution (again using the VWSS technique) to match latency requirements. Central to this approach is the utilization of Continuous Wavelet Transforms (CWTs), which do not substantively suffer from those energy leakage issues found in more commonly used transforms such as Discrete Wavelet Transforms (DWT). A robust numerical implementation of CWTs is presented via a particular class of Convolutional Neural Networks (CNNs) called Robust Convex Relaxation (RCR)-based Convolutional Long Short-Term Memory Deep Neural Networks (a.k.a., CLSTMDNNs or CLNNs). By employing small convolutional filters, this class leverages deeper cascade learning, which nicely emulates CWTs. In addition to its use for convex relaxation adversarial training, the RCR framework also improves the bound tightening for the successive convolutional layers (which contain the cascading of ever smaller “CWT-like” convolutional filters). In this paper, we explore this particular architecture for its discernment capability among the SuT time series being compared. To operationalize this architectural paradigm, non-conventional Nonnegative Matrix Factorization (NMF) and Multiresolution Matrix Factorization (MMF) is used in conjunction to facilitate the capture of the structure and content of the involved matrices so as to achieve higher resolution and enhanced discernment accuracy. The desired WT (a.k.a., Corresponding WT or CORWT) resulting from the MMF is implemented as a translation-invariant CWT PyWavelet to better illuminate the intricate structural characteristics of the SuT and facilitate the analysis/discernment of their constituent Waveforms of Interest (WoIs). A precomputed hash and lookup table is utilized to facilitate WoI classification and discernment in quasi-real-time.
Characteristics of fluorinated amorphous carbon films and implementation of 0.15 μm Cu/a-C:F damascene interconnection (2001)

Fluorinated amorphous carbon films (a-C:F) deposited by plasma enhanced chemical vapor deposition with low dielectric constant (K∼2.3), thermal stability (higher than 400 °C) and acceptable adhesion to a cap layer such as SiOF or SiO2 were obtained by varying the range of content ratios between carbon and fluorine, the rf power, the process pressure and the base temperature. Standard x-ray photoelectron spectroscopy and thermal desorption spectroscopy metrologies were employed to characterize the deposited a-C:F films. The damascene pattern with 0.15 μm and an etching selectivity of more than 50 (a-C:F/SiOF, SiO2) was implemented by a mixture of etching gases of N2+O2. The bias power, rf power and gas flows were incorporated to optimize the etching recipe for achieving a damascene profile with a high aspect ratio. The scanning electron microscope results showed that a better etch profile can be obtained at higher bias power. In our damascene architecture, the etching stop layer or hard mask of both SiOF and SiO2 was studied. The SiOF, providing a lower dielectric constant than SiO2, would especially reduce the entire effective dielectric constant. Furthermore, we integrated electroplated copper into trenches or vias as small as 0.15 μm, with aspect ratio of 6.
