Behavioral and Pharmacological Studies on Gluten Exorphin A5, a Newly Isolated Bioactive Food Protein Fragment, in Mice (2000)

Central effects of gluten exorphin A5 (Gly-Tyr-Tyr-Pro-Thr), a fragment from wheat gluten, were studied on the pain-inhibitory system, emotionality and learning/memory processes in mice. Orally administered gluten exorphin A5 produced neither an antinociceptive effect nor an effect on morphine analgesia. Intracerebroventricularly (i.c.v.) administered gluten exorphin A5 produced mild but significant antinociception in a dose-depepndent manner, while not affecting the morphine analgesia. On the other hand, oral gluten exorphin A5 suppressed the endogenous pain-inhibitory system, i.e., antinociception induced by socio-psychological- (PSY-) stress (SIA) using a communication box; intraperitoneal gluten exorphin A5 abolished both footshock- (FS-) stress-induced antinociception (SIA) and PSY-SIA; and i.c.v. gluten exorphin A5 suppressed FS-SIA, but rather potentiated PSY-SIA. This peptide given by these routes was without effect on forced swim-SIA. In addition, oral gluten exorphin A5 tended to prolong the retention time on open arms in the elevated plus-maze test. Finally, oral gluten exorphin A5 when given during the post-training period of learning/memory processes significantly increased the latency into the dark compartment in the one-trail step-though type passive avoidance test, indicating that the peptide also facilitates the acquire/consolidation process of learning/memory. Thus, gluten exorphin A5 has been found to produce various effects not only in the peripheral nervous systems but also in the central nervous system.
Death, Social Networks and Virtual Worlds: A Look Into the Digital Afterlife (2011)

As users increasingly operate in various social networking sites and virtual worlds for online interaction, the prevalence of one's online personal presence grows along with the amount of personal information contained in these environments. As our online identities are infused with our every day "real" lives, the virtual can have consequences far beyond a daily status update, online friends and 3D representations. What happens when our content, data, messages and other creations are no longer in our control after we are gone? The authors of this paper examine issues involving the use of these online identities, after an individual is deceased. Specifically, the authors examine virtual worlds and social networking sites in respect to death, and as a way to memorialize an individual. What content is left behind as part of one's digital "legacy"? The authors discuss their preliminary work and future research directions in the area of the effect of death on social networking and virtual worlds.
X-ray photo-emission and energy dispersive spectroscopy of HA coated titanium (1997)

The purpose of this study was to determine the chemical composition changes of hydroxyapatite (HA) coated titanium using surface analysis (x-ray photo-emission) and bulk analysis (energy dispersive spectroscopy). The specimens examined were controls, 30 minutes and 3 hours aged specimens in distilled water or 0.2M sodium phosphate buffer (pH 7.2) at room temperature. Each x-ray photo-emission cycle consisted of 3 scans followed by argon sputtering for 10 minutes for a total of usually 20 cycles, corresponding to a sampling depth of {approximately} 1500 {angstrom}. The energy dispersive spectroscopy analysis was on a 110 by 90 {mu}m area for 500 sec. Scanning electron microscopy examination showed crystal formation (3P{sub 2}O{sub 5}*2CAO*?H{sub 2}O by energy dispersive spectroscopy analysis) on the HA coating for the specimens aged in sodium phosphate buffer. The x-ray photo-emission results indicated the oxidation effect of water on the titanium (as TiO{sub 2}) and the effect of the buffer to increase the surface concentration of phosphorous. No differences in the chemical composition were observed by energy dispersive spectroscopy analysis. The crystal growth was only observed for the sodium phosphate buffer specimens and only on the HA surface.
A Theoretical Study of the Quantization Noise in Split Delta–Sigma ADCs (2008)

A theoretical analysis of the statistics of the quantization noise in split delta-sigma (DeltaSigma) analog-to-digital converters (ADCs) is presented. Sufficient conditions are derived that ensure that the quantization noise components of the constituent DeltaSigma modulators are asymptotically independent of each other, the input, delayed versions of themselves, and uniformly distributed. The application of the conditions is illustrated for two useful classes of split DeltaSigma ADCs.
Production of methane using offshore wind energy. Executive summary. Final report (1975)

This study has assessed the potential of the electrical generation by wind energy of hydrogen, converting it to methane, and introducing it into the present natural gas pipelines. This study is limited by NSF direction to the basic objectives of defining the electrochemical process, the theoretical feasibility, and the estimated cost of producing methane gas from wind energy using calcium carbonate from underwater sands. Two primary site locations were used, Nantucket Shoals off the coast of Massachusetts and Cape Hatteras shoal water areas. The study does not include any wind energy design optimized for the electrolysis process, or the special design requirements for offshore wind power. (GRA)
An approach for extraction, characterization and quantitation of microplastic in natural marine snow using Raman microscopy (2016)

Secure Data Retrieval for Decentralized Disruption-Tolerant Military Networks (2012)

Mobile nodes in military environments such as a battlefield or a hostile region are likely to suffer from intermittent network connectivity and frequent partitions. Disruption-tolerant network (DTN) technologies are becoming successful solutions that allow wireless devices carried by soldiers to communicate with each other and access the confidential information or command reliably by exploiting external storage nodes. Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policies update for secure data retrieval. Ciphertext-policy attribute-based encryption (CP-ABE) is a promising cryptographic solution to the access control issues. However, the problem of applying CP-ABE in decentralized DTNs introduces several security and privacy challenges with regard to the attribute revocation, key escrow, and coordination of attributes issued from different authorities. In this paper, we propose a secure data retrieval scheme using CP-ABE for decentralized DTNs where multiple key authorities manage their attributes independently. We demonstrate how to apply the proposed mechanism to securely and efficiently manage the confidential data distributed in the disruption-tolerant military network.
Determination of the Self-Diffusion Coefficient of Ni2+in La2NiO4+δby the Solid State Reaction Method (2012)

The growth of La2NiO4+δ at the interface between La2O3 and NiO has been studied from 950 to 1450°C in argon, air and oxygen. The thickness, microstructure and composition of the formed La2NiO4+δ layers have been characterized by means of SEM, EDX, EBSD, EPMA and XRD. The growth rate follows parabolic kinetics. It has been concluded from the position of Pt markers that La2NiO4+δ grows predominantly by solid state diffusion of Ni2+, and the experimental results were accordingly fitted with Wagner's expressions for self-diffusion. Above 1100°C the diffusion coefficients follow Arrhenius-type temperature dependencies, with activation energies 243 ± 21 and 218 ± 21 kJ/mol evaluated for the conditions at the La2O3/La2NiO4+δ and NiO/La2NiO4+δ interfaces, respectively. Below 1100°C the diffusivity falls more steeply with decreasing temperature, and possible explanations are discussed. Compared to cation diffusion in perovskite-type oxides, Ni2+ diffusivity in La2NiO4+δ is in higher range.
Intralesional Sodium Thiosulfate for the Treatment of Calciphylaxis (2013)

Intralesional sodium thiosulfate may be an effective and well-tolerated treatment for localized calciphylaxis. This novel approach requires further research and investigation.
Heterogeneous polymer systems. II. Mechanism of stabilization of polymeric oil‐in‐oil emulsions (1965)

Abstract Polymeric oil‐in‐oil emulsions (POO‐emulsions) are a new class of emulsions comprising two immiscible polymer solutions and a graft copolymer as an emulsifying agent. A mechanism of stabilization of POO‐emulsions has been proposed which explains why graft copolymers act as POO‐emulsifiers, why they accumulate in the interface of POO‐emulsions, and why they provide coalescence barriers. The basic hypothesis is that the emulsifying graft copolymers accumulate in the interface as a result of the phenomenon of phase separation of polymers in solution, and that this phenomenon also provides the repulsive forces between colliding droplets which stabilize POO‐emulsions. The formation of micelles of graft and block copolymers as a result of phase separation has been discussed, and a literature survey on the behavior of graft and block copolymers in solution has been included to support the proposed mechanism.
Lightweight security mechanisms for wireless video transmission (2002)

The paper introduces lightweight video encryption algorithms for transmission over wireless networks. The objective of these encryption algorithms is to reduce the total amount of data encrypted (while providing reasonable privacy and security) and to use multiple FEC codes to reduce the expected number of bit errors left in the data after decoding. The goal of this work is to provide encryption of video data while increasing the decodeability of the stream in the presence of network bit error. The first algorithm uses multi-layer video coding (which also helps to increase PSNR) for security and encrypts only a base layer. The second algorithm extends video encryption algorithms to deduce the amount of data encrypted and uses different BCH codes for each level.
Killing double bonds softly: the reduction of polymer-bound alkenes (2012)

Alkenes can be reduced through “transfer hydrogenation” with dimethylamine-borane adduct and Wilkinson's catalyst. This reaction can also be carried out by solid-phase synthesis as a heterogeneous reaction. Furthermore, the behaviour of various functional groups under hydrogenation conditions was tested.
Physiological and Molecular Alterations Promoted by Schizotetranychus oryzae Mite Infestation in Rice Leaves (2015)

Infestation of phytophagous mite Schizotetranychus oryzae in rice causes critical yield losses. To better understand this interaction, we employed Multidimensional Protein Identification Technology (MudPIT) approach to identify differentially expressed proteins. We detected 18 and 872 unique proteins in control and infested leaves, respectively, along with 32 proteins more abundant in control leaves. S. oryzae infestation caused decreased abundance of proteins related to photosynthesis (mostly photosystem II-related), carbon assimilation and energy production, chloroplast detoxification, defense, and fatty acid and gibberellin synthesis. On the contrary, infestation caused increased abundance of proteins involved in protein modification and degradation, gene expression at the translation level, protein partitioning to different organelles, lipid metabolism, actin cytoskeleton remodeling, and synthesis of jasmonate, amino acid, and molecular chaperones. Our results also suggest that S. oryzae infestation promotes cell-wall remodeling and interferes with ethylene biosynthesis in rice leaves. Proteomic data were positively correlated with enzymatic assays and RT-qPCR analysis. Our findings describe the protein expression patterns of infested rice leaves and suggest that the acceptor side of PSII is probably the major damaged target in the photosynthetic apparatus. These data will be useful in future biotechnological approaches aiming to induce phytophagous mite resistance in rice.
Constant-delay MSB-first bit-serial adder (2002)

A new MSB-first bit-serial adder/subtracter architecture is proposed. The architecture utilizes a modified Manchester carry chain to accommodate the carry from the future LSB's. The carry chain is shown to have the constant delay of two AND gates and one XOR gate regardless of the operand width, which allows a fast constant operational clock frequency. When compared to the conventional parallel addition approach where the operand bits are stored and then added in parallel, the proposed architecture also provides a significant area saving. It is also shown that the proposed architecture can be generalized for radix-<i>r</i> operands.
Allelic heterogeneity of molecular events in human coagulation factor IX in Asian Indians (2007)

Mutations in Factor IX gene (F9) cause X-linked recessive bleeding disorder hemophilia B. Here, we characterized molecular events in nine North Indian hemophiliac families identifying four missense mutations (three novel), two nonsense mutations, and a deletion. We have also captured the mutational spectrum of this disease in India based on available reports and established their genotype/phenotype relationships. Indian F9 mutations data indicate the absence of an important germline mutagen in the Indian subcontinent over the last century, and are consistent with previously made conclusions that universal, presumably endogenous factors are predominant in the causation of the spontaneous mutations in F9. We also analyzed the distribution of Ala194Thr polymorphism in 1231 Asian Indians and have established that Ala variant is far more frequent and can certainly be exploited for carrier detection, contrary to earlier reports.
Compensation of atmospheric CO2 buildup through engineered chemical sinkage (2001)

Retrieval of background carbon dioxide into regional chemical extractors would counter anthropogenic inputs in a manner friendly to established industries. We demonstrate via atmospheric transport/scaling calculations that for idealized flat removal units, global coverage could be less than two hundred thousand square kilometers. The disrupted area drops to a small fraction of this with engineering into the vertical to bypass laminarity. Fence structures and artificial roughness elements can both be conceived. Sink thermodynamics are analyzed by taking calcium hydroxide as a sample reactant. Energy costs could be minimized at near the endothermicity of binding reversal. In the calcium case the value is 25 kcal mole −1 , as against a fuel carbon content of 150 in the same units. Aqueous kinetics are less than favorable for the hydroxide, but misting could counteract slow liquid phase transfer. Properties of superior scrubbers are outlined.
Comprehensive Essentiality Analysis of the Mycobacterium tuberculosis Genome via Saturating Transposon Mutagenesis (2017)

Sequencing of transposon-insertion mutant libraries has become a widely used tool for probing the functions of genes under various conditions. The Himar1 transposon is generally believed to insert with equal probabilities at all TA dinucleotides, and therefore its absence in a mutant library is taken to indicate biological selection against the corresponding mutant. Through sequencing of a saturated Himar1 library, we found evidence that TA dinucleotides are not equally permissive for insertion. The insertion bias was observed in multiple prokaryotes and influences the statistical interpretation of transposon insertion (TnSeq) data and characterization of essential genomic regions. Using these insights, we analyzed a fully saturated TnSeq library for M. tuberculosis, enabling us to generate a comprehensive catalog of in vitro essentiality, including ORFs smaller than those found in any previous study, small (noncoding) RNAs (sRNAs), promoters, and other genomic features.

Determination of chlorine, bromine and iodine in milk samples by ICP-OES (2003)

A procedure coupling acid decomposition and precipitation, using inductively coupled plasma optical emission spectrometry (ICP- OES) is proposed for the determination of Cl, Br and I in milk samples. During the mineralization process in closed and open vessels (microwave ovens), anions are precipitated as salts of low solubility products (AgCl, AgBr and AgI). After separation from digestate solution, precipitates are dissolved with ammonia resulting in a 20% v/v solution. The final solution was directly introduced into the ICP-OES without any damage to the sample introduction system and with no severe spectral interference. Three biological reference materials were used to validate the methodology: Non-Fat Milk Powder SRM 1549 from NIST, Skim Milk Powder RM-151 from BCR and Whole Egg Powder RM 8415, also from NIST. The limits of detection (3σb/s) for Cl, Br and I in the solid sample were 30, 40 and 280 µg g−1 for the closed vessel microwave oven, and 15, 20 and 40 µg g−1 for the open vessel microwave oven, respectively. Relative standard deviations, considering five replicates of sample submitted to the proposed methodology, were 1% for Cl and Br, and 2% for I, when a closed vessel microwave was used. The results for Cl were in good agreement with the certified values (90% confidence level). For Br, recoveries ranged from 87 to 104% for closed vessel microwave oven and from 90 to 102% for open vessel microwave oven. As for I, recoveries ranged from 85 to 98% with a closed vessel microwave oven. Accurate results for determinations in certified materials and good recoveries demonstrated the efficiency of the procedure.

Manufacturability and optical functionality of multimode optical interconnections developed with fast processable and reliable polymer waveguide silicones (2015)

We report on the manufacturing, reliability, and optical functionality of multimode optical waveguide devices developed with a fast processable optical grade silicone. The materials show proven optical losses of &lt;0.05 dB/cm @ 850 nm, surviving &gt;2000 hours 85°C/85% relative humidity testing as well as &gt;4 cycles of wave solder reflow. Fabrication speeds of &lt;10 minutes are shown for a full waveguide stack. Step index 50×50 &mu;m waveguides were fabricated and passively MT connectorized on rigid FR4 and flexible polyimide substrates with precise alignment features (cut by dicing saw or ablated by UV laser). Two out-of-plane coupling techniques were demonstrated in this paper, a MT connectorized sample with a 45° turning lens as well as 45° dielectric mirrors on waveguides by dicing saw. Multiple connections between fiber and polymer waveguides with MPO and two out-of-plane coupling techniques in a complete optical link are demonstrated @ 10 Gbps data rates with commercial transceiver modules. Also, complex waveguide geometries such as turnings and crossings are demonstrated by QSFP+ transceiver. The eye diagram analyses show comparable results in functionality between silicone waveguide and fiber formats.

Xanthomonas oryzae pv. oryzae XopQ protein suppresses rice immune responses through interaction with two 14‐3‐3 proteins but its phospho‐null mutant induces rice immune responses and interacts with another 14‐3‐3 protein (2019)

Many bacterial phytopathogens employ effectors secreted through the type-III secretion system to suppress plant innate immune responses. The Xanthomonas type-III secreted non-TAL effector protein Xanthomonas outer protein Q (XopQ) exhibits homology to nucleoside hydrolases. Previous work indicated that mutations which affect the biochemical activity of XopQ fail to affect its ability to suppress rice innate immune responses, suggesting that the effector might be acting through some other pathway or mechanism. In this study, we show that XopQ interacts in yeast and in planta with two rice 14-3-3 proteins, Gf14f and Gf14g. A serine to alanine mutation (S65A) of a 14-3-3 interaction motif in XopQ abolishes the ability of XopQ to interact with the two 14-3-3 proteins and to suppress innate immunity. Surprisingly, the S65A mutant gains the ability to interact with a third 14-3-3 protein that is a negative regulator of innate immunity. The XopQS65A mutant is an inducer of rice immune responses and this property is dominant over the wild-type function of XopQ. Taken together, these results suggest that XopQ targets the rice 14-3-3 mediated immune response pathway and that its differential phosphorylation might enable interaction with alternative 14-3-3 proteins.
<title>Experimental reconstruction of a nonlocal nonlinear response function of a thermal medium</title> (2007)

We present a novel experimental technique for retrieving the spatial profile of a nonlocal response function in a medium with thermal nonlinearity. Our method is based on the quantitative measurement of the light-induced nonlinear phase distribution by holographic interferometry combined with an iterative process of two-dimensional deconvolution using the known pump beam intensity distribution.
A low voltage design technique for low noise RF integrated circuits (2002)

Analysis and optimization of the bias conditions and noise parameters of MOS devices are presented. A design technique based on a narrowband LC-folded cascode topology is proposed for low voltage RF integrated circuits. The technique is applied to the design of a 1 V LNA operating at 1.9 GHz using a 0.5 /spl mu/m CMOS technology. Simulation results show that the LNA provide a noise figure of 1.7 dB, gain of 10 dB, and is well matched at the input. The LNA also provides a minimum noise figure of 1.6 dB.
