Determination of Free Chlorine by Methyl Orange (1965)

This article discusses the methyl orange test as a satisfactory laboratory and field procedure for determining free and combined chlorine in water samples. All reagents used in the test are stable at room temperature and may be prepared from readily available chemicals. The test may theoretically be used to measure chlorine of any concentration; curves have been prepared for concentrations of up to 5.0 mg/l, although precision deteriorates slightly at the higher concentrations. The only serious interference is from manganese and this can be corrected through the use of an arsenite modification.
Trypsin-protease activated receptor-2 signaling contributes to pancreatic cancer pain (2017)

Pain treatment is a critical aspect of pancreatic cancer patient clinical care. This study investigated the role of trypsin-protease activated receptor-2 (PAR-2) in pancreatic cancer pain. Pancreatic tissue samples were collected from pancreatic cancer (n=22) and control patients (n=22). Immunofluorescence analyses confirmed colocalization of PAR-2 and neuronal markers in pancreatic cancer tissues. Trypsin levels and protease activities were higher in pancreatic cancer tissue specimens than in the controls. Supernatants from cultured human pancreatic cancer tissues (PC supernatants) induced substance P and calcitonin gene-related peptide release in dorsal root ganglia (DRG) neurons, and FS-NH<sub>2</sub>, a selective PAR-2 antagonist, inhibited this effect. A BALB/c nude mouse orthotopic tumor model was used to confirm the role of PAR-2 signaling in pancreatic cancer visceral pain, and male Sprague-Dawley rats were used to assess ambulatory pain. FS-NH<sub>2</sub> treatment decreased hunch scores, mechanical hyperalgesia, and visceromotor reflex responses in tumor-bearing mice. In rats, subcutaneous injection of PC supernatant induced pain behavior, which was alleviated by treatment with FS-NH<sub>2</sub> or FUT-175, a broad-spectrum serine protease inhibitor. Our findings suggest that trypsin-PAR-2 signaling contributes to pancreatic cancer pain <i>in vivo</i>. Treatment strategies targeting PAR-2 or its downstream signaling molecules might effectively relieve pancreatic cancer pain.
Attention Based Spatial-Temporal Graph Convolutional Networks for Traffic Flow Forecasting (2019)

Forecasting the traffic flows is a critical issue for researchers and practitioners in the field of transportation. However, it is very challenging since the traffic flows usually show high nonlinearities and complex patterns. Most existing traffic flow prediction methods, lacking abilities of modeling the dynamic spatial-temporal correlations of traffic data, thus cannot yield satisfactory prediction results. In this paper, we propose a novel attention based spatial-temporal graph convolutional network (ASTGCN) model to solve traffic flow forecasting problem. ASTGCN mainly consists of three independent components to respectively model three temporal properties of traffic flows, i.e., recent, daily-periodic and weekly-periodic dependencies. More specifically, each component contains two major parts: 1) the spatial-temporal attention mechanism to effectively capture the dynamic spatialtemporal correlations in traffic data; 2) the spatial-temporal convolution which simultaneously employs graph convolutions to capture the spatial patterns and common standard convolutions to describe the temporal features. The output of the three components are weighted fused to generate the final prediction results. Experiments on two real-world datasets from the Caltrans Performance Measurement System (PeMS) demonstrate that the proposed ASTGCN model outperforms the state-of-the-art baselines.
Vertical Lift Models Substantiated by Statfjord Field Data (2012)

Abstract The Statfjord field entered into the blow down phase after 30 years of production. Production of injection gas and gas liberated from residual oil is the main production target in this phase. In some areas, the gas cap has been produced and the wells are producing mainly water until the solution gas is mobilized. These wells have gone through large changes in gas-liquid-ratio (GLR) and water-cut (WCT). Production tests from wells located in such areas have been used when analyzing the ability of multiphase-flow correlations to model vertical lift performance (VLP). Accurate modeling of the VLP is critical to predict a realistic production rate during the blow down phase. Measured wellhead (THP) and downhole pressures from about 80 production tests, from four wells, were used to analyze the accuracy of VLP correlations at widely varying flow conditions (GLR, WCT, and THP). Altogether 17 multiphase pressure drop correlations incorporated in the program Prosper were tested by comparing observed and calculated downhole pressures. Based on the production tests the ability of the different correlations to predict the VLP varies with the following top 4: Hagedorn Brown, Petroleum Experts, Petroleum Experts 2, and Petroleum Experts 3. These correlations are recommended if no measured data is available. In general a somewhat low pressure drop is predicted at low gas-liquid ratio (GLR), and a somewhat high pressure drop is predicted at high GLR. After tuning, accurate predictability was observed for the different correlations for limited ranges in GLR e.g. 50-300 Sm3/Sm3. However, for larger ranges in GLR it was not possible to achieve an accurate VLP correlation, even after tuning. Hagedorn Brown and Petroleum experts seem to be the most accurate correlations for a wide range of producing GLR. The error in the predicted production performance when a single VLP correlation is used can be substantial for highly productive wells with large variations in producing GLR. It is recommended to shift the tuning following the GLR development.
Polymer based smart flexible thermopile for power generation (2004)

In this study, a flexible thermoelectric power generator has been proposed. The proposed thermoelectric power generator is composed of a Ni-Cu thermopile on a polymer sheet, and heat sink and heat absorber sheets. The flexible thermoelectric power generator has 60 mm-length, 45 mm-width and 3 mm-height. The flexible thermoelectric power generator may be possible to apply on a free form surface. As a result of characteristic evaluation, Seebeck voltage of 15.4 /spl mu/V/K per thermocouple was obtained, and a prospect for practical application was confirmed.
Tolerability and safety of fluvoxamine and other antidepressants (2006)

Selective serotonin [5-hydroxytryptamine (5-HT)] reuptake inhibitors (SSRIs) and the 5-HT noradrenaline reuptake inhibitor, venlafaxine, are mainstays in treatment for depression. The highly specific actions of SSRIs of enhancing serotonergic neurotransmission appears to explain their benefit, while lack of direct actions on other neurotransmitter systems is responsible for their superior safety profile compared with tricyclic antidepressants. Although SSRIs (and venlafaxine) have similar adverse effects, certain differences are emerging. Fluvoxamine may have fewer effects on sexual dysfunction and sleep pattern. SSRIs have a cardiovascular safety profile superior to that of tricyclic antidepressants for patients with cardiovascular disease; fluvoxamine is safe in patients with cardiovascular disease and in the elderly. A discontinuation syndrome may develop upon abrupt SSRI cessation. SSRIs are more tolerable than tricyclic antidepressants in overdose, and there is no conclusive evidence to suggest that they are associated with an increased risk of suicide. Although the literature suggests that there are no clinically significant differences in efficacy amongst SSRIs, treatment decisions need to be based on considerations such as patient acceptability, response history and toxicity.

Modulation by Melatonin of the Pathogenesis of Inflammatory Autoimmune Diseases (2013)

Melatonin is the major secretory product of the pineal gland during the night and has multiple activities including the regulation of circadian and seasonal rhythms, and antioxidant and anti-inflammatory effects. It also possesses the ability to modulate immune responses by regulation of the T helper 1/2 balance and cytokine production. Autoimmune diseases, which result from the activation of immune cells by autoantigens released from normal tissues, affect around 5% of the population. Activation of autoantigen-specific immune cells leads to subsequent damage of target tissues by these activated cells. Melatonin therapy has been investigated in several animal models of autoimmune disease, where it has a beneficial effect in a number of models excepting rheumatoid arthritis, and has been evaluated in clinical autoimmune diseases including rheumatoid arthritis and ulcerative colitis. This review summarizes and highlights the role and the modulatory effects of melatonin in several inflammatory autoimmune diseases including multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, type 1 diabetes mellitus, and inflammatory bowel disease.
Radical Scavenging and Anti-Lipoperoxidative Activities of<i>Smallanthus sonchifolius</i>Leaf Extracts (2005)

Radical scavenging and anti-lipoperoxidative effects of two organic fractions and two aqueous extracts from the leaves of a neglected Andean crop-yacon (Smallanthus sonchifolius Poepp. & Endl., Asteraceae) were determined using various in vitro models. The extracts' total phenolic content was 10.7-24.6%. They exhibited DPPH (IC50 16.14-33.39 microg/mL) and HO* scavenging activities (4.49-6.51 mg/mL). The extracts did not scavenge phenylglyoxylic ketyl radicals, but they retarded their formation. In the xanthine/xanthine oxidase superoxide radical generating system, the extracts' activities were 26.10-37.67 superoxide dismutase equivalents/mg. As one of the extracts displayed xanthine oxidase inhibitory activity, the effect of the extracts on a nonenzymatically generated superoxide was determined (IC50 7.36-21.01 microg/mL). The extracts inhibited t-butyl hydroperoxide-induced lipoperoxidation of microsomal and mitochondrial membranes (IC50 22.15-465.3 microg/mL). These results make yacon leaves a good candidate for use as a food supplement in the prevention of chronic diseases involving oxidative stress.
A nano-opto-mechanical pressure sensor via ring resonator (2012)

This paper reports a nano-opto-mechanical pressure sensor based on nano-scaled ring resonator. The pressure is measured through the output spectrum shift which is induced via mechanical deformation of the ring resonator. The sensitivity as high as 1.47 pm/kPa has been experimentally achieved which agrees with numerical prediction. Due to the strong variation of sensitivity with different ring radius and thickness of the diaphragm, the pressure sensor can be used to form an array structure to detect the pressure distribution in highly accurate measurement with low-cost advantages. The nano-opto-mechanical pressure sensor has potential applications such as shear stress displacement detection, pressure wave detector and pressure mapping etc.

Spontaneous Eye Blinking, a Measure of Dopaminergic Function, in Children With Acquired Immunodeficiency Syndrome (1997)

The higher blink rates in human immunodeficiency virus-infected children with more severe cortical abnormalities suggest increased central dopamine activity compared with that in children without cortical computed tomographic brain scan abnormalities. Thus, as a result of structural brain abnormalities, neurotransmitter levels in children with acquired immunodeficiency syndrome may vary and this may be reflected in their socioemotional functioning.

Late Miocene alluvial sediments from the Teruel area: Magnetostratigraphy, magnetic susceptibility, and facies organization (1997)

[EN] We present the paleomagnetic dating of the upper Miocene red alluvial to palustrine sequences of the area north of Teruel. The magnetostratigraphy\nof the Masada del Valle and Masada Ruea sections indicates a minimum age of about 11 Ma to the lowermost sediments\npost-dating the unconformity over the Mesozoic basement. The overall Miocene sequence represents a retrogradation of the alluvial\nsystem, grading upwards into palustrinellacustrine sedimentation. The onset of palustrine deposition is dated in Masada Ruea at\nabout 9.7 Ma. The late Vallesian faunas of Masía del Barbo, of which leve1 2B is the reference locality of biochronozone MNlO, are\ndated to 9.3 Ma. The anisotropy of magnetic susceptibility (AMS) in the tenigenous sediments suggests that the orientation of the magnetic\nellipsoids represents the paleocurrent direction. Paleocurrent interpretations based on AMS data can be used for a better comprehension\nof the facies arrangement in the Neogene sediments of the Teniel basin.p=2
Reduction of extrinsic base-collector capacitance in InP/InGaAs SHBTs using a new base pad design (2003)

A method to isolate the base pad from the intrinsic device structure for reducing the extrinsic base-collector capacitance of InP/InGaAs single heterojunction bipolar transistors(SHBTs) is reported, which uses a new base pad layout. The new layout is designed based on the lateral etching characteristics of an InGaAs collector layer with different crystal orientations. The new layout allows more effective and easier base pad isolation for InP-based HBTs, which have the emitter aligned to [011] or [011~] directions, without excessive lateral or additional etching. The maximum f/sub T/ and f/sub max/ of the fabricated device with a 2 /spl times/ 10 /spl mu/m/sup 2/ emitter size using the new layout were found to be 72 and 242 GHz, respectively.
An algorithm for a real time measurement of nonlinear transition shift by a time domain correlation analysis (1995)

An algorithm has been developed for a real time measurement of the nonlinear transition shift in high areal density magnetic recording, by a time domain correlation analysis. By measuring SNR and a correlation coefficient of the time domain readback voltages, r[/spl nu/(t), /spl nu/(t+/spl epsiv//2+(M/sub 1/-1/2)T)], written by a pseudorandom sequence, we can determine the nonlinear transition shift in real time. This new algorithm not only simplifies data processing of the readback waveform, but also includes noise effects on the nonlinear transition shift measurement. This algorithm has been implemented by LeCroy Corporation into their 7200-A high-speed digital oscilloscope. The LeCroy oscilloscope measures the nonlinear transition shift in less than 100 ms utilizing this algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Semantic Web Primer, 2nd Edition (Cooperative Information Systems) (2008)

Deoxyribonucleic acid (DNA) is considered as one of the alternative materials for electronic device applications; however, DNA has critical limitation to electronic device applications due to its low electrical conductivity and unreliability. Therefore, it is required for electronic devices to prepare the well defined conductive polymer nanowires with DNA as a template. Polypyrrole (PPy) is an attractive polymer due to its high conductivity and environmental stability in bulk; although it is well known that ammonium persulfate (APS) used for the polymerization of pyrrole causes the deformation of DNA molecules. We minimized the damage of immobilized DNA strands on (3-aminopropyl) triethoxysilane (APTES) modified silicon wafer during APS polymerization. Atomic force microscopy (AFM) images from different APS treatment times and from using the vortex process obviously showed the effect on the synthesis of individual and continuous polypyrrole nanowires (PPy NWs). The PPy NWs at various pyrrole concentrations had similar height; however, the higher concentration gave more residues. Fourier transform-infrared spectroscopy (FT-IR) spectroscopy provided the strong evidence that PPy NWs were successfully synthesized on the DNA strands.
A delta-sigma modulator with a phase-to-digital and digital-to-phase quantizer (2011)

A phase-based delta-sigma analog-to-digital converter (ADC) architecture with a combination voltage-controlled and digitally-controlled delay lines (VCDL-DCDL) is presented. The architecture uses this VCDL-DCDL combination as the phase-domain counterparts of an ADC-DAC in a traditional delta-sigma modulator. Simulation results of the new modulator achieve a 60.1 dB SNR, or a 9.7 bit over a 10 MHz bandwidth.
Multi-hash based Pattern Matching Mechanism fo r High-Performance Intrusion Detection (2009)

Many Network-based Intrusion Detection Systems (NIDSs) are developed till now to respond these network attacks. As network technology presses forward, Gigabit Ethernet has become the actual standard for large network installations. Therefore, software solutions in developing high-speed NIDSs are increasingly impractical. It thus appears well motivated to investigate the hardware-based solutions. Although several solutions have been proposed recently, finding an efficient solution is considered as a difficult problem due to the limitations in resources such as a small memory size, as well as the growing link speed. Therefore, we propose the FPGA-based intrusion detection technique to detect and respond variant attacks on high-speed links. It was designed to fully exploit hardware parallelism to achieve real-time packet inspection, to require a small memory for storing signature. The technique is a part of our system, called ATPS (Adaptive Threat Prevention System) recently developed. Most of all, the proposed system has a novel content filtering technique called Table-driven Bottom-up Tree (TBT) for exact string matching. However, as the number of signatures to be compared is growing rapidly, the improved mechanism is required. In this paper, we present the multi-hash based TBT technique with memory-efficiency. Simulation based performance evaluations showed that the proposed technique used on-chip SRAM less than 20% of the one-hash based TBT technique. Finally, experimental results about our system show a consistent performance in traffic level and had nothing to do with increasing number of signatures applied.

Design Parameters for LLDPE Film Resin Selection (1985)

A wide variety of LLDPE resins have been run on laboratory through commercial scale blown film lines. The film properties fit into two classes, butene copolymers in one, and higher alpha-olefins in a second, higher strength class. Within each class the film properties have been correlated with resin density and melt flow properties. These relationships can help converters to choose the optimum LLDPE resin for each specific application.
Named entity recognition using hundreds of thousands of features (2003)

We present an approach to named entity recognition that uses support vector machines to capture transition probabilities in a lattice. The support vector machines are trained with hundreds of thousands of features drawn from the CoNLL-2003 Shared Task training data. Margin outputs are converted to estimated probabilities using a simple static function. Performance is evaluated using the CoNLL-2003 Shared Task test set; Test B results were Fβ=1 = 84.67 for English, and Fβ=1 = 69.96 for German.
TNF Mediates the Sustained Activation of Nrf2 in Human Monocytes (2011)

Modulation of monocyte function is a critical factor in the resolution of inflammatory responses. This role is mediated mainly by the production of TNF-α. Investigations of the actions of TNF have mostly focused on acute activation of other cell types such as fibroblasts and endothelial cells. Less is known about the effects of TNF on monocytes themselves, and little is known about the regulation of cell responses to TNF beyond the activation of NF-κB. In this study, we investigated the regulation of NF-E2-related factor 2 (Nrf2) cyctoprotective responses to TNF in human monocytes. We found that in monocytes TNF induces sustained Nrf2 activation and Nrf2 cytoprotective gene induction in a TNFR1-dependent manner. Under TNF activation, monocytes increased their expression of Nrf2-dependent genes, including NAD(P)H:quinone oxidoreductase 1 and glutamyl cysteine ligase modulatory, but not heme oxygenase-1. We also showed that autocrine TNF secretion was responsible for this sustained Nrf2 response and that Nrf2 activation by TNF was mediated by the generation of reactive oxygen species. Moreover, we showed that Nrf2-mediated gene induction can modulate TNF-induced NF-κB activation. These results show for the first time, to our knowledge, that TNF modulates prolonged Nrf2-induced gene expression, which in turn regulates TNF-induced inflammatory responses.
