Garbage collection for embedded systems (2004)

Security concerns on embedded devices like cellular phones make Java an extremely attractive technology for providing third-party and user-downloadable functionality. However, garbage collectors have typically required several times the maximum live data set size (which is the minimum possible heap size) in order to run well. In addition, the size of the virtual machine (ROM) image and the size of the collector's data structures (metadata) have not been a concern for server- or workstation-oriented collectors.We have implemented two different collectors specifically designed to operate well on small embedded devices. We have also developed a number of algorithmic improvements and compression techniques that allow us to eliminate almost all of the per-object overhead that the virtual machine and the garbage collector require. We describe these optimizations and present measurements of the Java embedded benchmarks (EEMBC) of our implementations on both an IA32 laptop and an ARM-based PDA.For applications with low to moderate allocation rates, our optimized collector running on the ARM is able to achieve 85% of peak performance with only 1.05 to 1.3 times the absolute minimum heap size. For applications with high allocation rates, the collector achieves 85% of peak performance with 1.75 to 2.5 times the minimum heap size. The collector code takes up 40 KB of ROM, and collector metadata overhead has been almost completely eliminated, consuming only 0.4% of the heap.
On error-correction performance and implementation of polar code list decoders for 5G (2017)

Polar codes are a class of capacity achieving error correcting codes that has been recently selected for the next generation of wireless communication standards (5G). Polar code decoding algorithms have evolved in various directions, striking different balances between error-correction performance, speed and complexity. Successive-cancellation list (SCL) and its incarnations constitute a powerful, well-studied set of algorithms, in constant improvement. At the same time, different implementation approaches provide a wide range of area occupations and latency results. 5G puts a focus on improved error-correction performance, high throughput and low power consumption: a comprehensive study considering all these metrics is currently lacking in literature. In this work, we evaluate SCL-based decoding algorithms in terms of error-correction performance and compare them to low-density parity-check (LDPC) codes. Moreover, we consider various decoder implementations, for both polar and LDPC codes, and compare their area occupation and power and energy consumption when targeting short code lengths and rates. Our work shows that among SCL-based decoders, the partitioned SCL (PSCL) provides the lowest area occupation and power consumption, whereas fast simplified SCL (Fast-SSCL) yields the lowest energy consumption. Compared to LDPC decoder architectures, different SCL implementations occupy up to 17.1 X less area, dissipate up to 7.35 x less power, and up to 26 X less energy.
Visibility Silhouettes for Semi‐Analytic Spherical Integration (2013)

Abstract At each shade point, the spherical visibility function encodes occlusion from surrounding geometry, in all directions. Computing this function is difficult and point‐sampling approaches, such as ray‐tracing or hardware shadow mapping, are traditionally used to efficiently approximate it. We propose a semi‐analytic solution to the problem where the spherical silhouette of the visibility is computed using a search over a 4D dual mesh of the scene. Once computed, we are able to semi‐analytically integrate visibility‐masked spherical functions along the visibility silhouette, instead of over the entire hemisphere. In this way, we avoid the artefacts that arise from using point‐sampling strategies to integrate visibility, a function with unbounded frequency content. We demonstrate our approach on several applications, including direct illumination from realistic lighting and computation of pre‐computed radiance transfer data. Additionally, we present a new frequency‐space method for exactly computing all‐frequency shadows on diffuse surfaces. Our results match ground truth computed using importance‐sampled stratified Monte Carlo ray‐tracing, with comparable performance on scenes with low‐to‐moderate geometric complexity.

Model-space compensation of microphone and noise for speaker-independent speech recognition (2003)

Ambient noise (additive distortion) and microphone changes (convolutive distortion) are two sources of distortion that may severely degrade speech recognition performance in real operating environments. Simultaneously modeling the two distortion sources has been a great challenge for robust speech recognition. A method, called JAC (Joint compensation of Additive and Convolutive distortions), is presented. It uses two log-spectral domain components in speech acoustic models to represent additive and convolutive distortions. The method adapts HMM mean vectors with a noise estimate and a channel estimate. The noise estimate is calculated from the pre-utterance pause and the channel estimate is calculated using an EM algorithm from speech utterances produced in the distortion environment. Evaluated on a noisy speech database recorded in-vehicle with a hands-free distant microphone in several driving conditions, the algorithm reduces recognition word error rate in typical operating conditions by an order of magnitude.
Extruded Non-Crosslinked Foams Made from Ethylene-Styrene Interpolymers and Blends with Polyethylene (1999)

Ethylene-styrene Interpolymers (ESI) are a new class of polymers made by copolymerisation of ethylene and styrene monomers using INSITE® Technology, the patented constrained geometry single site catalysts and proprietary solution process of The Dow Chemical Company. The tradename of the Interpolymers is INDEX®. Foams with novel and unique properties have been made by expanding these polymers using physical blowing agents. This paper describes the properties of foams made from Interpolymers and blends with polyethylene.
NADH and NRH as potential dietary supplements or pharmacological agents for early liver injury caused by acute alcohol exposure (2021)

Alcoholism leads to many diseases, and it is also the social and economic burden of the society. Alcohol intake is the main cause of acute liver injury and chronic liver disease. Here, the ameliorative effect of NADH and dihydronicotinamide riboside (NRH) against alcohol-induced liver damage was studied and its possible mechanism was further clarified. In vitro studies showed that NADH and NRH are effective NAD+ concentration-enhancing agents. Compared with NMN, NADH and NRH can provide greater NAD+ increase at the same concentrations. Intraperitoneal injection of NADH and NRH in C57BL/6J mice also significantly increased the NAD+ content in liver, blood, brain, fat and kidney. Importantly, NADH and NRH significantly increased the liver NAD+/NADH ratio, but did not induce apoptosis markers in cells. The intragastric administration of 500 mg/kg NRH, 500 mg/kg NADH 15 min prior to acute alcohol ingestion (8 ml/kg, 40% w/v, in tap water) could dramatically enhance alcohol metabolism as revealed by the reduced concentrations of ethanol and acetaldehyde in blood as well as the decreased duration of the loss of righting reflex (LORR). Both Pretreatment and posttreatment with NADH or NRH could significantly reduce the increase of serum aspartate transaminase (AST) and alanine transaminase (ALT) after alcohol administration, indicating that they have a certain therapeutic effect on alcoholic hepatotoxicity besides preventing the adverse effects caused by alcohol. NADH and NRH could also alleviate lipid peroxidation as indicated by the repressed malondialdehyde (MDA) level and the elevated activities of superoxide dismutase (SOD) in liver tissues. Additionally, NADH or NRH can mitigate the abnormal lipid metabolism in acute alcoholic liver damage. These benefits obviously suggested that NADH or NRH could be a potential nutraceutical or pharmacological agent for promoting alcohol metabolism and preventing or treating early liver injury caused by acute alcohol exposure.
162. Crossing the Blood-Cerebrospinal Fluid Barrier in the Mouse Choroid Plexus With an Engineered Receptor/Ligand System (2015)

Crossing the blood-brain and the blood-cerebrospinal fluid barriers are one of the fundamental challenges in the development of new therapeutic molecules for brain disorders because they prevent entry of most drugs from the blood into the brain. However, some large molecules, like the protein transferrin, cross these barriers using a specific receptor that transports them into the brain. Mimicking nature, we engineered a receptor/ligand system to cross the brain barrier by combining the human transferrin receptor with the cohesin domain from Clostridium thermocellum, and we tested it in the choroid plexus of the mouse brain with a dockerin ligand. By expressing our receptor in choroidal ependymocytes, which are part of the blood-cerebrospinal fluid barrier, we found that our systemically administrated ligand was able to bind to the receptor and accumulate in ependymocytes, where some of the ligand was transported from the blood side to the brain side.
Synthesis and spasmolytic activity of aminoalkyl 2-substituted-2-(1,2-benzisoxazol-3-yl)acetates. (1987)

Several aminoalkyl esters of 2- (1, 2-benzisoxazol-3-yl) -2-cyclohexylacetic acid, 1- (1, 2-benzisoxazol-3-yl) -1-cyclopentanecarboxylic acid, and 1- (1, 2-benzisoxazol-3-yl) -1-cyclohexanecarboxylic acid and their quaternary ammonium salts were synthesized. The anticholinergic (anti-Ach) and musculotropic (anti-KCl) activities of these compounds were examined. Among them, 3- (N, N-diethylamino) -propyl 2- (1, 2-benzisoxazol-3-yl) -2-cyclohexylacetate (8b) showed potent anti-Ach and anti-KCl activities.

Optical and Acoustic Sensing of Lean Blowout Precursors (2002)

Approaches for identifying precursor events to lean blowout (LBO) in premixed or partially premixed combustors have been examined. This work characterizes the behavior of a premixed, swirl stabilized dump combustor near the lean blowout equivalence ratio limit using chemiluminescence (optical) and acoustic radiation emissions from the combustor. The results show that the transient behavior of the flame as lean blowout is approached can be characterized by short duration, localized extinction and reignition events. These events increase in frequency and duration as LBO is approached. Several methods based on signal thresholding, statistical analysis and frequency analysis are presented to transform the raw sensor output into a simple LBO proximity measure for use in an active control system. The thresholding approach utilizing the optical sensor provides the fastest time response. The sensor requirements for such systems are also presented, and it is shown that they can be met with practical devices.
Determination of the rate of cerebral oxygen consumption and regional cerebral blood flow by non-invasive <sup>17</sup>O <i>in vivo</i> NMR spectroscopy and magnetic resonance imaging: Part 2. Determination of CMRO<sub>2</sub>, for the rat by <sup>17</sup>O NMR, and CMRO<sub>2</sub>, rCBF and the partition coefficient for the cat by <sup>17</sup>O MRI (1993)

The rate of oxygen consumption (CMRO2) in intact rat and cat brains was calculated by novel data analysis methods from data obtained in in vivo 17O NMR spectroscopy and imaging inhalation studies. Data analysis methods of 17O inhalation measurements are applied to the calculation of CMRO2, regional cerebral blood flow (rCBF), the reflow (R), the arterial venous difference (AVD) and the partition coefficient (lambda). Several of the applied methods for the determination of CMRO2 do not require measurements of regional cerebral blood flow and H2 17O arterial concentration. The proposed methods have been tested, and the results obtained by the different methods are in very good agreement. It is shown that 17O NMR is unique in providing the rate of blood water flow, where the natural abundance 17O NMR signal consists of an internal reference and that lambda is essentially 1. The average values of CMRO2 for rats and cats were found to be 2.09 +/- 0.35 and 1.18 +/- 0.58 (mumol/O2/g tissue)/min, respectively. The average value for rCBF for the cat was found to be 0.38 +/- 0.12 [(mg/g)/min]. The average value for lambda was found to be 1.00 +/- 0.04. The ratio of AVD due to organs other than the brain to AVD due to the brain is smaller than 1 for the rat and the cat. The time and spatial resolution accuracy of the spectroscopic and imaging methods are compared, discussed and statistically analysed. It is concluded that the accuracy of determination of CMRO2 for the rat is higher than for the cat by a factor of 8.

Airborne wind profiling algorithms for the pulsed 2-micron coherent doppler Lidar at NASA Langley Research Center (2013)

Two versions of airborne wind profiling algorithms for the pulsed 2-micron coherent Doppler lidar system at NASA Langley Research Center in Virginia are presented. Each algorithm utilizes different number of line-of-sight (LOS) lidar returns while compensating the adverse effects of different coordinate systems between the aircraft and the Earth. One of the two algorithms APOLO (Airborne Wind Profiling Algorithm for Doppler Wind Lidar) estimates wind products using two LOSs. The other algorithm utilizes five LOSs. The airborne lidar data were acquired during the NASA’s Genesis and Rapid Intensification Processes (GRIP) campaign in 2010. The wind profile products from the two algorithms are compared with the dropsonde data to validate their results.
Polarization‐independent liquid‐crystal‐etalon modulator (2009)

Abstract— The experimental demonstration of a polarization‐independent high‐transmission field‐sequential liquid‐crystal‐etalon modulator for portable projection‐display application is presented. Polarization independence allows for high transmission efficiency for laser illumination sources using the polarization diversity method of speckle reduction. These devices can also be considered for LED illumination sources; however, the spectral width of current LEDs does not allow for high efficiency, especially for the green channel. These devices demonstrate millisecond switching needed for field‐sequential‐color generation.
Improved configuration control for redundant robots (1990)

Abstract This article presents a singularity‐robust task‐prioritized reformulation of the configuration control scheme for redundant robot manipulators. This reformulation suppresses large joint velocities near singularities, at the expense of small task trajectory errors. This is achieved by optimally reducing the joint velocities to induce minimal errors in the task performance by modifying the task trajectories. Furthermore, the same framework provides a means for assignment of priorities between the basic task of end‐effector motion and the user‐defined additional task for utilizing redundancy. This allows automatic relaxation of the additional task constraints in favor of the desired end‐effector motion, when both cannot be achieved exactly. The improved configuration control scheme is illustrated for a variety of additional tasks, and extensive simulation results are presented.

Monoclonal antibody to a major glycoprotein immunogen mediates differential complement-independent lysis of Trichomonas vaginalis (1986)

An immunoglobulin G type 2a (IgG2a) monoclonal antibody (MAb), designated C20A3, which reacts with a highly immunogenic trichomonad membrane glycoprotein (approximately 270,000 daltons), produced complement-independent cytolysis of Trichomonas vaginalis organisms. Time- and temperature-dependent lysis of parasites was observed following incubation of washed, live T. vaginalis with certain concentrations of C20A3 IgG. Differential killing of trichomonal isolates and clones of a given isolate by C20A3 was dependent on the presence of the glycoprotein antigen on the parasite surface.

Machine learning models identify multimodal measurements highly predictive of transdiagnostic symptom severity for mood, anhedonia, and anxiety (2018)

Abstract Background: Insights from neuroimaging-based biomarker research have not yet translated into clinical practice. This translational gap could be because of a focus of psychiatric biomarker research on diagnostic classification, rather than on prediction of transdiagnostic psychiatric symptom severity. Currently, no transdiagnostic, multimodal predictive models of symptom severity that include neurobiological characteristics have been described. Methods: We built predictive models of three common symptoms in psychiatric disorders (dysregulated mood, anhedonia, and anxiety) from the Consortium for Neuropsychiatric Phenomics dataset (n=272) which contains clinical scale assessments, resting-state functional-MRI (rs-fMRI) and structural-MRI (sMRI) imaging measures from patients with schizophrenia, bipolar disorder, attention deficit and hyperactivity disorder, and healthy control subjects. We used an efficient, data-driven feature selection approach to identify the most predictive features from these high-dimensional data. Results: This approach optimized modeling and explained 65-90% of variance across the three symptom domains, compared to 22% without using the feature selection approach. The top performing multimodal models retained a high level of interpretability which enabled several clinical and scientific insights. First, to our surprise, structural features did not substantially contribute to the predictive strength of these models. Second, the Temperament and Character Inventory scale emerged as a highly important predictor of symptom variation across diagnoses. Third, predictive rs-fMRI connectivity features were widely distributed across many intrinsic resting-state networks (RSN). Conclusions: Combining rs-fMRI with select questions from clinical scales enabled high levels of prediction of symptom severity across diagnostically distinct patient groups and revealed that connectivity measures beyond a few intrinsic RSNs may carry relevant information for symptom severity.
Genomic organization and functional characterization of the mouse <i>GalR1</i> galanin receptor (1997)

Galanin mediates diverse physiological functions in digestive, endocrine, and central nervous systems through G-protein-coupled receptors. Two galanin receptors have been cloned but the gene structures are unknown. We report genomic and cDNA cloning of the mouse GalR1 galanin receptor and demonstrate that the coding sequence is uniquely divided into three exons encoding the N-terminal portion through the fifth transmebrane domain, the third intracellular loop, and the sixth transmembrane domain through the C-terminus. Functional analysis of the encoded cDNA revealed active ligand binding and intracellular signaling. The expression is detected in brain, spinal cord, heart and skeletal muscle.
Liquid crystal field effect displays (1973)

A number of products have been introduced which make use of the response of nematic liquid crystal which has a positive dielectric anisotropy. Because of the large range of materials which are now available, device design can now be varied to include applications which were not previously available. New devices designed must take into consideration speed of response, electrical breakdown and voltage threshold and as all of these parameters are interrelated some engineering compromises become necessary. This paper will develop the scientific basis for the engineering compromises needed in the design of a number of liquid crystal displays. A review of available displays and their threshold voltages will be presented. The breakdown voltage limitations as a function of the thickness of the displays as well as the speed of response will be discussed.
