Expression of angiogenic factors in juvenile rheumatoid arthritis: Correlation with revascularization of human synovium engrafted into SCID mice (2001)

JRA synovium is characterized by high angiogenic activity. SCID mouse-human JRA synovium chimeras may provide a good approach to study the in vivo regulation of angiogenesis in JRA.
Site model acquisition and extension from aerial images (2002)

A system has been developed to acquire, extend and refine 3D geometric site models from aerial imagery. This system hypothesizes potential building roofs in an image, automatically locates supporting geometric evidence in other images, and determines the precise shape and position of the new buildings via multiimage triangulation. Model-to-image registration techniques are applied to align new, incoming images against the site model. Model extension and refinement procedures are then performed to add previously unseen buildings and to improve the geometric accuracy of the existing 3D building models.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Deaths: final data for 2007. (2010)

Objectives-This report presents final 2007 data on U.S. deaths, death rates, life expectancy, infant and maternal mortality, and trends by selected characteristics such as age, sex, Hispanic origin, race, marital status, educational attainment, injury at work, state of residence, and cause of death. Methods-Information reported on death certificates, which are completed by funeral directors, attending physicians, medical examiners, and coroners, is presented in descriptive tabulations. The original records are filed in state registration offices. Statistical information is compiled in a national database through the Vital Statistics Cooperative Program of the Centers for Disease Control and Prevention's National Center for Health Statistics. Causes of death are processed in accordance with the International Classification of Diseases, Tenth Revision. Results-In 2007, a total of 2,423,712 deaths were reported in the United States. The age-adjusted death rate was 760.2 deaths per 100,000 standard population, a decrease of 2.1 percent from the 2006 rate and a record low historical figure. Life expectancy at birth rose 0.2 year, from a 2006 value of 77.7 years to a record 77.9 in 2007. Age-specific death rates decreased for most age groups-15-24, 35-44, 45-54, 55-64, 65-74, 75-84, and 85 and over-and remained unchanged for the age groups of under age 1, 1-4, 5-14, and 25-34. The 15 leading causes of death in 2007 remained the same as in 2006 with the exception of two causes that exchanged ranks. Alzheimer's disease, the seventh leading cause of death in 2006, became the sixth leading cause in 2007, and Diabetes mellitus, the sixth leading cause in 2006, dropped to the seventh leading cause in 2007. Heart disease and cancer continued to be the leading and second-leading causes of death, respectively, together accounting for almost one-half of all deaths (48.6 percent). The infant mortality rate in 2007 was 6.75 deaths per 1,000 live births. Conclusions-Mortality patterns in 2007, such as the decline in the age-adjusted death rate to a record historical low, were generally consistent with long-term trends. Life expectancy reached a record high in 2007, increasing 0.2 year from 2006.
Mechanistic Insights into Replication Termination as Revealed by Investigations of the Reb1- <i>Ter3</i> Complex of <i>Schizosaccharomyces pombe</i> (2008)

Relatively little is known about the interaction of eukaryotic replication terminator proteins with the cognate termini and the replication termination mechanism. Here, we report a biochemical analysis of the interaction of the Reb1 terminator protein of Schizosaccharomyces pombe, which binds to the Ter3 site present in the nontranscribed spacers of ribosomal DNA, located in chromosome III. We show that Reb1 is a dimeric protein and that the N-terminal dimerization domain of the protein is dispensable for replication termination. Unlike its mammalian counterpart Ttf1, Reb1 did not need an accessory protein to bind to Ter3. The two myb/SANT domains and an adjacent, N-terminal 154-amino-acid-long segment (called the myb-associated domain) were both necessary and sufficient for optimal DNA binding in vitro and fork arrest in vivo. The protein and its binding site Ter3 were unable to arrest forks initiated in vivo from ars of Saccharomyces cerevisiae in the cell milieu of the latter despite the facts that the protein retained the proper affinity of binding, was located in vivo at the Ter site, and apparently was not displaced by the "sweepase" Rrm3. These observations suggest that replication fork arrest is not an intrinsic property of the Reb1-Ter3 complex.
Non‐Volatile Photochemical Gating of an Epitaxial Graphene/Polymer Heterostructure (2011)

A novel heterostructure based on epitaxial graphene grown on silicon carbide combined with two polymers is demonstrated, with a neutral spacer and a photoactive layer that provides potent electron acceptors under UV light exposure. UV exposure of this heterostructure enables control of the electrical parameters of graphene in a non-invasive, non-volatile, and reversible way.

Diffusion of Gold and Silver in Bisphenol A Polycarbonate (1997)

Diffusion of evaporated gold and silver into Bisphenol A polycarbonate has been studied using the radiotracer technique in combination with ion beam sputtering for serial sectioning. Diffusion coefficients between 4 × 10-14 and 1 × 10-16 cm2 s-1 were measured in the temperature range between 210 and 130 °C. The metal concentration in the polymer turned out to depend strongly on the evaporation rate. An Arrhenius-like temperature dependence with activation energies of 1.02 eV for silver and 1.13 eV for gold was found. The low diffusivities, which are not affected by the polymer dynamics, are interpreted within molecular theories for diffusion of gases in polymers with an additional attractive interaction between metal atoms and polymer chains.
Methyl(hydrido)platinum(IV) Complexes with Flexible Tridentate Nitrogen-Donor Ligands (2003)

The flexible, unsymmetrical triamine ligands NNN = N,N,N‘-trimethyl-N‘-(2-pyridylmethyl)ethylenediamine (PICO), N-benzyl-N‘,N‘-dimethyl-N-(2-picolyl)ethylenediamine (BPICO), and N,N‘,N‘ ‘-pentamethyldiethylenetriamine (PMDETA) act as bidentate ligands in forming square-planar dimethylplatinum(II) complexes cis-[PtMe2(NNN)]. These complexes undergo oxidative addition with MeI to give the platinum(IV) complexes fac-[PtMe3(NNN)]I, in which the ligand NNN is fac-tridentate in [PtMe3(NNN)]I when NNN = PICO or BPICO, but in equilibrium with bidentate NNN in [PtIMe3(NNN)] when NNN = PMDETA. Protonation of the complexes cis-[PtMe2(NNN)] gave the corresponding dimethyl(hydrido)platinum(IV) complexes, [PtHMe2(NNN)]X (X = BF4-, CF3SO3-, CF3CO2-), often as a mixture of isomers whose structures were deduced from the NMR spectra. These hydridoplatinum(IV) complexes undergo reductive elimination of methane to give the methylplatinum(II) complexes [PtMe(NNN)]X, in which NNN is a mer-tridentate ligand, with the rate of reaction for NNN = PMDETA > PICO, BPICO. In all cases, H/D exchange experiments indicate reversibility of the protonation and methyl(hydride) to methane complex steps in the reaction sequence.
Deep Learning Based HEVC In-Loop Filtering for Decoder Quality Enhancement (2018)

High Efficiency Video Coding (HEVC), which is the latest video coding standard currently, achieves up to 50% bit rate reduction compared to previous H.264/AVC standard. While performing the block based video coding, these lossy compression techniques produce various artifacts like blurring, distortion, ringing, and contouring effects on output frames, especially at low bit rates. To reduce those compression artifacts HEVC adopted two post processing filtering technique namely de-blocking filter (DBF) and sample adaptive offset (SAO) on the decoder side. While DBF applies to samples located at block boundaries, SAO nonlinear operation applies adaptively to samples satisfying the gradient based conditions through a lookup table. Again SAO filter corrects the quantization errors by sending edge offset values to decoders. This operation consumes extra signaling bit and becomes an overhead to network. In this paper, we proposed a Convolutional Neural Network (CNN) based architecture for SAO in-loop filtering operation without modifying anything on encoding process. Our experimental results show that our proposed model outperformed previous state-of-the-art models in terms of BD-PSNR (0.408 dB) and BD-BR (3.44%), measured on a widely available standard video sequences.
A novel oncogenic pathway by TLS–CHOP involving repression of MDA-7/IL-24 expression (2012)

Designing Energy-Efficient Intermittently Powered Systems Using Spin-Hall-Effect-Based Nonvolatile SRAM (2017)

Intermittently powered systems represent a new class of batteryless devices that operate solely on energy harvested from their environment. Due to the unreliable nature of ambient energy sources, these devices experience frequent intervals of power loss, leading to sudden reboots. Tolerating such power supply disruptions require the ability to rapidly checkpoint/save system state when power loss is imminent and restore it at the start of the next power cycle to continue computations in a seamless manner. A typical microcontroller used in these systems consists of a fast nonvolatile SRAM and a nonvolatile Flash storage. Prior work has shown how emerging nonvolatile memory technologies such as STT-MRAM can improve the energy efficiency of these systems, either by using STT-MRAM as a drop-in replacement for Flash (henceforth referred to as the SRAM+STT-MRAM memory configuration) or using STT-MRAM as unified memory (henceforth referred to as the unified STT-MRAM memory configuration). However, both these configurations have significant drawbacks. Using the SRAM+STT-MRAM configuration leads to high checkpointing overhead due to the inefficient write operations of STT-MRAM whereas using the unified STT-MRAM configuration is inefficient due to executing every program instruction directly from STT-MRAM. This paper proposes a novel Spin Hall Effect-based nonvolatile-SRAM (SNVRAM) bit-cell that combines the nonvolatility of spin devices with the speed and energy efficiency of conventional 6T SRAM cells. We explore the use of the proposed SNVRAM to replace the SRAM in a transiently powered system to mitigate the drawbacks of the aforementioned memory configurations. Simulation results using a set of evaluation benchmarks demonstrate that the SNVRAM+STT-MRAM configuration leads to significant memory energy benefits of $2.6\times $ and $2.8\times $ on average, compared to the SRAM+STT-MRAM and unified STT-MRAM memory configurations, respectively.
Scalable architecture for word HMM-based speech recognition and VLSI implementation in complete system (2006)

This paper describes a scalable architecture for real-time speech recognizers based on word hidden Markov models (HMMs) that provide high recognition accuracy for word recognition tasks. However, the size of their recognition vocabulary is small because its extremely high computational costs cause long processing times. To achieve high-speed operations, we developed a VLSI system that has a scalable architecture. The architecture effectively uses parallel computations on the word HMM structure. It can reduce processing time and/or extend the word vocabulary. To explore the practicality of our architecture, we designed and evaluated a complete system recognizer, including speech analysis and noise robustness parts, on a 0.18-/spl mu/m CMOS standard cell library and field-programmable gate array. In the CMOS standard-cell implementation, the total processing time is 56.9 /spl mu/s/word at an operating frequency of 80 MHz in a single system. The recognizer gives a real-time response using an 800-word vocabulary.
Collaboration between human and nonhuman players in Night Vision Tactical Trainer-Shadow (2016)

The Night Vision Tactical Trainer - Shadow (NVTT-S) is a U.S. Army-developed training tool designed to improve critical Manned-Unmanned Teaming (MUMT) communication skills for payload operators in Unmanned Aerial Sensor (UAS) crews. The trainer is composed of several Government Off-The-Shelf (GOTS) simulation components and takes the trainee through a series of escalating engagements using tactically relevant, realistically complex, scenarios involving a variety of manned, unmanned, aerial, and ground-based assets. The trainee is the only human player in the game and he must collaborate, from his web-based mock operating station, with various non-human players via spoken natural language over simulated radio in order to execute the training missions successfully. Non-human players are modeled in two complementary layers - OneSAF provides basic background behaviors for entities while NVTT provides higher level models that control entity actions based on intent extracted from the trainee’s spoken natural dialog with game entities. Dialog structure is modeled based on Army standards for communication and verbal protocols. This paper presents an architecture that integrates the U.S. Army’s Night Vision Image Generator (NVIG), One Semi- Automated Forces (OneSAF), a flight dynamics model, as well as Commercial Off The Shelf (COTS) speech recognition and text to speech products to effect an environment with sufficient entity counts and fidelity to enable meaningful teaching and reinforcement of critical communication skills. It further demonstrates the model dynamics and synchronization mechanisms employed to execute purpose-built training scenarios, and to achieve ad-hoc collaboration on-the-fly between human and non-human players in the simulated environment.
Research on subjective stereoscopic image quality assessment (2009)

Research on stereoscopic image and video processing has been the new trend in the recent years. Measurement of visual quality is of fundamental importance for numerous stereoscopic image and video processing applications. The goal of quality assessment is to automatically assess the quality of images or videos in agreement with human quality judgments and optimize the stereoscopic image or video systems. Unfortunately, human are lack of the knowledge for the perception quality of stereoscopic images. In this paper, we present experimental results of an extensive subjective quality assessment experiment for stereoscopic images in which a total 400 distorted stereoscopic images were evaluated by about twenty human subjects. The stereoscopic images quality data obtained from 8,000 individual human quality judgments is used to build a database that can be exploited for understanding perception of stereoscopic images and provide data for objective assessment metrics designing. The experimental results indicated that the quality perception of the distorted stereoscopic images is content and distortion types dependent.

Genetic Recombination in<i>Bacillus subtilis</i>168: Contribution of Holliday Junction Processing Functions in Chromosome Segregation (2004)

Bacillus subtilis mutants classified within the epsilon (ruvA, DeltaruvB, DeltarecU, and recD) and eta (DeltarecG) epistatic groups, in an otherwise rec+ background, render cells impaired in chromosomal segregation. A less-pronounced segregation defect in DeltarecA and Deltasms (DeltaradA) cells was observed. The repair deficiency of addAB, DeltarecO, DeltarecR, recH, DeltarecS, and DeltasubA cells did not correlate with a chromosomal segregation defect. The sensitivity of epsilon epistatic group mutants to DNA-damaging agents correlates with ongoing DNA replication at the time of exposure to the agents. The Deltasms (DeltaradA) and DeltasubA mutations partially suppress the DNA repair defect in ruvA and recD cells and the segregation defect in ruvA and DeltarecG cells. The Deltasms (DeltaradA) and DeltasubA mutations partially suppress the DNA repair defect of DeltarecU cells but do not suppress the segregation defect in these cells. The DeltarecA mutation suppresses the segregation defect but does not suppress the DNA repair defect in DeltarecU cells. These results result suggest that (i) the RuvAB and RecG branch migrating DNA helicases, the RecU Holliday junction (HJ) resolvase, and RecD bias HJ resolution towards noncrossovers and that (ii) Sms (RadA) and SubA proteins might play a role in the stabilization and or processing of HJ intermediates.
Flavin–iodine coupled organocatalysis for the aerobic oxidative direct sulfenylation of indoles with thiols under mild conditions (2018)

Asthma and allergy patterns over 18 years after severe RSV bronchiolitis in the first year of life (2010)

Severe early RSV bronchiolitis is associated with an increased prevalence of allergic asthma persisting into early adulthood. Small airway dysfunction (LCI) is related to current asthma and airway inflammation but not to RSV bronchiolitis. Reduced spirometry after RSV may reflect airway remodelling.
Efficient Solid-State Photoluminescence in New Poly(2,5-dialkoxy-<i>p</i>-phenyleneethynylene)s (1996)

A series of novel poly(2,5-dialkoxy-p-phenyleneethynylene)s (PPEs) has been prepared by the palladium-catalyzed cross-coupling polycondensaton of aryl acetylenes and aryl iodides. Different alkoxy side chains including n-hexadecyloxy, n-octyloxy, (2-ethylhexyl)oxy, (2-methylpropyl)oxy, (3-(dimethylamino)propyl)oxy, and (7-carboxyheptyl)oxy groups were attached to the rigid-rod polymer main chain. With this structural concept, polymers having an identical conjugated backbone but different supramolecular structures in the solid state could be achieved. X-ray diffraction measurements on thin films show that the polymers which have sterically hindered side chains are essentially disordered, while those with only linear side chains can form lamellar structures with significant degrees of long-range order. High photoluminescence (PL) quantum yields, up to 0.86 in solution and 0.36 in the solid state, have been measured for the new materials. While the solution quantum yields are independent of the functionalization, solid-state quantum efficiencies were found to be related to the degree of long-range order in the samples, decreasing with increasing order. The coplanar orientation of the conjugated polymer backbones is assumed to lead to the formation of excimer complexes which provide nonemissive decay channels for the excited states. These nonemissive orientations are more significant in the materials having a greater degree of long-range order.
An optimal receiver using a time-dependent adaptive filter (2003)

The optimal time-dependent receiver (OTDR) is presented and shown to be superior to the conventional matched filter receiver when cyclostationary interference is present. This performance advantage is explained by viewing both the OTDR and the conventional matched filter receiver as time-dependent filters that use the spectral correlation properties of the signal. The matched filter is periodic at the baud rate of the signal of interest whereas the OTDR is periodic at the baud rate of the signal of interest and any other statistical periodicity of the received signal (including that of the interfering signal). These additional filter periodicities provide the OTDR with the capability of exploiting additional spectral correlation characteristics, thus providing superior performance. Simulations are presented to show the bit-error-rate performance advantage of the OTDR (a new demodulation scheme for digitally modulated signals).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis, Characterization, and Release Mechanisms of Polymers Containing Pendant Herbicides (1977)

Recently, there has been a growing interest in developing pesticide controlled release technology. Much of the impetus has resulted from demands for enhanced agricultural production at lower levels of environmental risk. Most of the activity has been directed toward formulations in which the pesticide is physically dissolved or dispersed in a polymer matrix. Polymers have been prepared in our laboratories which contain labile polymer to pesticide covalent bonds. These linkages are susceptible to aqueous and/or bacterial break-down, resulting in long-term release. Theoretically, the rate of herbicide release can be controlled by changing the nature of the labile bonds or by altering the cross-link density of the polymer. The synthesized systems have been characterized by IR, NMR, U.V., GPC, etc. Release studies have been conducted in aqueous media using U.V. and gas chromatography. In addition, soil mobility and phytotoxicity studies are in progress.
Measurements of Rate Constants for Termolecular Reactions of O(3<i>P</i>) with NO, O2, CO, N2, and CO2 Using a Pulsed Vacuum-uv Photolysis—Chemiluminescent Method (1971)

Absolute rate constants for a number of termolecular reactions of O atoms were determined at 300°K. Oxygen atoms were generated by pulsed vacuum-uv photolyses of NO, O2, CO2, and N2O and were monitored by NO2* or CO2* chemiluminescent emission. The rate constants k, in units of cm6 molecule−2·second−1, for the following reactions are: O+NO+NO→NO2+NO, k=1.5×10−31 (± 10 %) O+NO+He→NO2+He, k=6.65×10−32 (± 10%) O+O2+O2→O3+O2, k=6.4×10−34 (± 25 %) O+O2+N2→O3+N2, k=5.4×10−34 (± 25 %) O+O2+CO→O3+CO, k=6.7×10−34 (± 25 %) O+CO+CO→CO2+CO, k=3.2×10−36 (± 25 %) O+CO+N2→CO2+N2, k=2.2×10−36 (± 25 %) O+CO+He→CO2+He, k=1.7×10−36 (± 25 %) O+CO2+CO→CO3+CO, k〈9×10−36 O+N2+N2→N2O+N2, k〈5×10−38.
