Embedding spatial context information into inverted filefor large-scale image retrieval (2012)

One most popular approach for large-scale content-based image retrieval is based on the Bag-of-Visual-Words model. Since the spatial context among local features is very important for visual content identification, many approaches index local features' geometric clues, such as location, scale and orientation for post-verification. To obtain consistent accuracy performance, the amount of top ranked images that post-verification approach needs to process is proportional to the image database size. When the database is very large, the verified images will be too many to be processed in real-time response. To address this issue, in this paper, we explore two approaches to embed spatial context information into the inverted file. The first one is to build a spatial relationship dictionary embedded with spatial context among local features, which we call one-one spatial relationship method. The second one is to generate a spatial context binary signature for each feature, which we call one-multiple spatial relationship method. Then we build an inverted file with spatial information between local features. The geometric verification is implicitly achieved while traversing the inverted file. Experimental results on benchmark Holidays dataset demonstrate the efficiency of the proposed algorithm.

An RC Logarithmic Converter-Digitizer (1978)

Theoretical considerations and experimental data support the suggestion that high accuracy of conversion and long-term stability could be obtained with a logarithmic RC converter-digitizer. The operation of the proposed converter is based on time measurements of the exponential voltage decay across a linear RC network. Linearity error of this converter, built with commonly available and noncritical components, was found to be less than 0.05 percent of full scale for a two-decade operation.
5-HT2 Antagonist Ritanserin in Neuroleptic-Induced Parkinsonism (1990)

Several studies support the hypothesis of 5-HT (serotonin) involvement in the physiopathology of the extrapyramidal system. Ritanserin is a new compound with a high, selective, and long-lasting binding affinity for 5-HT2 receptors. A therapeutic effect of ritanserin has been reported in Parkinson's tremor and L-Dopa-induced dyskinesias but no effect was seen in essential tremor. In this double-blind comparative study with orphenadrine (150 mg daily p.o.) and placebo, ritanserin (30 mg daily p.o.) was administered to 36 schizophrenic outpatients who were being treated with neuroleptic drugs and who had parkinsonism. For a period of 3 weeks, the treatment was added to the antipsychotic therapy after a 7-day washout from previous antiparkinson medication. Psychopathology was rated weekly by the Brief Psychiatric Rating Scale and showed no significant changes during the trial. The Mindham Rating Scale was used to assess symptoms of parkinsonism; at week 3, ritanserin was superior to orphenadrine (p less than 0.03) and to placebo (p less than 0.01). The results confirm previous observations of the therapeutic efficacy of ritanserin on neuroleptic-induced parkinsonism, and support the hypothesis that serotonin influences extrapyramidal physiopathology.

Skidding Characteristics of Pavement Surfaces Incorporating Steel Slag Aggregates (1996)

Steel slag, a by-product of the steel industry, has been used in road construction in South Yorkshire and its environs for the past 60 years. Local highway engineers have anecdotal evidence of good long-term antiskid performance from road surfacings that incorporate steel slag aggregate, and these materials have remained popular with users. In view of the move toward performance measurements for paving materials, a systematic study of the performance of paving materials incorporating slag has been set up as a combined industry-university project with the assistance of the Teaching Company Directorate. The evaluation of the skid resistance characteristics of steel slag aggregates and the skidding characteristics of pavement surfaces incorporating steel slag aggregate are reported. The research program developed a modified specimen preparation procedure that significantly reduced the scatter in polished stone value (PSV) results. The field data showed that all steel slag surfaces provided good long-term skid resistance and that the 14-mm chippings exceed the performance expectations of rock chippings with similar PSVs.
TopicMachine: Conversion Prediction in Search Advertising Using Latent Topic Models (2014)

Search Engine Marketing (SEM) agencies manage thousands of search keywords for their clients. The campaign management dashboards provided by advertisement brokers have interfaces to change search campaign attributes. Using these dashboards, advertisers create test variants for various bid choices, keyword ideas, and advertisement text options. Later on, they conduct controlled experiments for selecting the best performing variants. Given a large keyword portfolio and many variants to consider, campaign management can easily become a burden on even experienced advertisers. In order to target users in need of a particular service, advertisers have to determine the purchase intents or information needs of target users. Once the target intents are determined, advertisers can target those users with relevant search keywords. In order to formulate information needs and to scale campaign management with increasing number of keywords, we propose a framework called Topic Machine, where we learn the latent topics hidden in the available search terms reports. Our hypothesis is that these topics correspond to the set of information needs that best match-make a given client with users. In our experiments, Topic Machine outperformed its closest competitor by 41 percent on predicting total user subscriptions.
Electrical power generation from residual biomass by combustion in externally fired gas turbines (EFGT) (2017)

The rising interest in developing gas turbines make it important to investigate them in energy generation from solid biomass. Addiotionally, externally fired gas turbine plant has the advantage of solid fuel flexibility. Pressure and air mass flow through the clean cycle side are optimized to provide the maximum power. Hardware-in-the-loop (HiL) is integrated beside the real combustion process. It serves in being more flexible in tuning plant parameters for several values, for instance, heat exchanger design, compressor and turbine efficiencies, and pressure and mass flow values.
Comparison of <scp>GEANT4</scp> very low energy cross section models with experimental data in water (2010)

The GEANT4-DNA physics models available in the GEANT4 toolkit have been compared in this article to available experimental data in the water vapor phase as well as to several published recommendations on the mass stopping power. These models represent a first step in the extension of the GEANT4 Monte Carlo toolkit to the simulation of biological effects of ionizing radiation.
<title>Comparison of sensors in the 0.9- to 14-micron region against beach obstacles and mines</title> (2002)

Results include a statistical and subjective analysis of the imagery. Emphasis is placed on sensor performance during thermal crossover, day/night transitions, and nighttime operations. Also the sensitivity required for imaging obstacles in water is measured.
Transcriptional Activation Domain of the Herpesvirus Protein VP16 Becomes Conformationally Constrained upon Interaction with Basal Transcription Factors (1996)

The transcriptional activation domain of the herpesvirus protein VP16 resides in the carboxyl-terminal 78 amino acids (residues 413-490). Fluorescence analyses of this domain indicated that critical amino acids are solvent-exposed in highly mobile segments. To examine interactions between VP16 and components of the basal transcriptional machinery, we incorporated (at position 442 or 473 of VP16) tryptophan analogs that can be selectively excited in complexes with other Trp-containing proteins. TATA-box binding protein (TBP) (but not transcription factor B (TFIIB)) caused concentrationdependent changes in the steady-state anisotropy of VP16, from which equilibrium binding constants were calculated. Quenching of the fluorescence from either position (442 or 473) was significantly affected by TBP, whereas TFIIB affected quenching only at position 473. 7-aza-Trp residues at either position showed a emission spectral shift in the presence of TBP (but not TFIIB), indicating a change to a more hydrophobic environment. In anisotropy decay experiments, TBP reduced the segmental motion at either position; in contrast, TFIIB induced a slight change only at position 473. Our results support models of TBP as a target protein for transcriptional activators and suggest that ordered structure in the VP16 activation domain is induced upon interaction with target proteins.
Functionalisation of [Mo<sub>6</sub>O<sub>19</sub>]<sup>2–</sup>with aromatic amines: synthesis and structure of a hexamolybdate building block with linear difunctionality (1995)

In reactions between the hexamolybdate [Mo6O19]2– and 1,4-diaminobenzene, terminal oxides are replaced by 4-aminophenylimido ligands and the first structurally characterised polyoxometallate to contain functionalised organoimido ligands, (Bun4)2[Mo6O17(NC6H4NH2)2]5, is also the first example of a trans-bis(imido) derivative; further condensation also occurs to yield species in which hexamolybdate units are linked by 1,4-phenylenediimido bridges.

CD56brightCD16− Killer Ig-Like Receptor− NK Cells Display Longer Telomeres and Acquire Features of CD56dim NK Cells upon Activation (2007)

Human NK cells can be divided into CD56(dim)CD16(+) killer Ig-like receptors (KIR)(+/-) and CD56(bright)CD16(-) KIR(-) subsets that have been characterized extensively regarding their different functions, phenotype, and tissue localization. Nonetheless, the developmental relationship between these two NK cell subsets remains controversial. We report that, upon cytokine activation, peripheral blood (PB)-CD56(bright) NK cells mainly gain the signature of CD56(dim) NK cells. Remarkably, KIR can be induced not only on CD56(bright), but also on CD56(dim) KIR(-) NK cells, and their expression correlates with lower proliferative response. In addition, we demonstrate for the first time that PB-CD56(dim) display shorter telomeres than PB- and lymph node (LN)-derived CD56(bright) NK cells. Along this line, although human NK cells collected from nonreactive LN display almost no KIR and CD16 expression, NK cells derived from highly reactive LN, efferent lymph, and PB express significant amounts of KIR and CD16, implying that CD56(bright) NK cells could acquire these molecules in the LN during inflammation and then circulate through the efferent lymph into PB as KIR(+)CD16(+) NK cells. Altogether, our results suggest that CD56(bright)CD16(-) KIR(-) and CD56(dim)CD16(+)KIR(+/-) NK cells correspond to sequential steps of differentiation and support the hypothesis that secondary lymphoid organs can be sites of NK cell final maturation and self-tolerance acquisition during immune reaction.

Elevated Hypothalamic Glucocorticoid Levels Are Associated With Obesity and Hyperphagia in Male Mice (2016)

Glucocorticoid (Gc) excess, from endogenous overproduction in disorders of the hypothalamic-pituitary-adrenal axis or exogenous medical therapy, is recognized to cause adverse metabolic side effects. The Gc receptor (GR) is widely expressed throughout the body, including brain regions such as the hypothalamus. However, the extent to which chronic Gcs affect Gc concentrations in the hypothalamus and impact on GR and target genes is unknown. To investigate this, we used a murine model of corticosterone (Cort)-induced obesity and analyzed Cort levels in the hypothalamus and expression of genes relevant to Gc action. Mice were administered Cort (75 μg/mL) or ethanol (1%, vehicle) in drinking water for 4 weeks. Cort-treated mice had increased body weight, food intake, and adiposity. As expected, Cort increased plasma Cort levels at both zeitgeber time 1 and zeitgeber time 13, ablating the diurnal rhythm. Liquid chromatography dual tandem mass spectrometry revealed a 4-fold increase in hypothalamic Cort, which correlated with circulating levels and concentrations of Cort in other brain regions. This occurred despite decreased 11β-hydroxysteroid dehydrogenase (Hsd11b1) expression, the gene encoding the enzyme that regenerates active Gcs, whereas efflux transporter Abcb1 mRNA was unaltered. In addition, although Cort decreased hypothalamic GR (Nr3c1) expression 2-fold, the Gc-induced leucine zipper (Tsc22d3) mRNA increased, which indicated elevated GR activation. In keeping with the development of hyperphagia and obesity, Cort increased Agrp, but there were no changes in Pomc, Npy, or Cart mRNA in the hypothalamus. In summary, chronic Cort treatment causes chronic increases in hypothalamic Cort levels and a persistent elevation in Agrp, a mediator in the development of metabolic disturbances.
Adaptive decision feedback equalization for digital satellite channels using multilayer neural networks (1995)

This paper introduces an adaptive decision feedback equalization using the multilayer perceptron structure of an M-ary PSK signal through a TDMA satellite radio channel. The transmission is disturbed not only by intersymbol interference (ISI) and additive white Gaussian noise, but also by the nonlinearity of transmitter amplifiers. The conventional decision feedback equalizer (DFE) is not well-suited to detect the transmitted sequence, whereas the neural-based DFE is able to take into account the nonlinearities and therefore to detect the signal much better. Nevertheless, the applications of the traditional multilayer neural networks have been limited to real-valued signals. To overcome this difficulty, a neural-based DFE is proposed to deal with the complex PSK signal over the complex-valued nonlinear MPSK satellite channel without performing time-consuming complex-valued back-propagation training algorithms, while maintaining almost the same computational complexity as the original real-valued training algorithm. Moreover, a modified back-propagation algorithm with better convergence properties is derived on the basis of delta-bar-delta rule. Simulation results for the equalization of QPSK satellite channels show that the neural-based DFE provides a superior bit error rate performance relative to the conventional mean square DFE, especially in poor signal-to-noise ratio conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Long-Term Outcome of Hepatitis C Infection after Liver Transplantation (1996)

After liver transplantation for HCV-related cirrhosis, persistent HCV infection can cause severe graft damage, and such damage is more frequent in patients infected with HCV genotype 1b than with other genotypes. After five years, the rates of graft and overall survival are similar between patients with and those without HCV infection.
AmbientRT --- Real Time System Software Support for Data Centric Sensor Networks (2005)

We present the architecture and design of a real time operating system for mobile wireless sensor networks. AmbientRT is being developed for environments with very limited resources in order to relieve the burden of the developer and to use the resources of the node efficiently. The paper presents the main concepts used and the trade-offs involved in the system. Initial results show that with the current hardware available for sensor networks, the real time concept is feasible. For real-time scheduling, we have designed EDFI. EDFI is a lightweight real-time scheduling protocol that combines EDF (earliest deadline first) with deadline inheritance over shared resources. EDFI is precise with task admission control, very efficient with scheduling and dispatching, and straightforward in feasibility analysis.
Porous Silicon Oxide Layer Formation by the Electrochemical Treatment of a Porous Silicon Layer (1990)

A porous silicon layer (PSL) with pores of 40–200Å diam was electrochemically treated at cathodic potentials in an aqueous solution. The treatment gave rise to the increase in proportion of silicon oxides. The surface had a porous structure of 0.5–2 μm diam after the electrochemical treatment. A comparison study using He‐Ne laser irradiation of the PSL was done that showed no distinct effects in the cathodic reaction rate compared with the electrochemical method. A surface‐type humidity sensor was fabricated using the electrochemically treated silicon and found to be sensitive to changes in humidity over a wide range.
Horizontal axis wind turbine systems: optimization using genetic algorithms (2001)

Abstract A method for the optimization of a grid‐connected wind turbine system is presented. The behaviour of the system components is coupled in a non‐linear way, and optimization must take into account technical and economical aspects of the complete system design. The annual electrical energy cost is estimated using a cost model for the wind turbine rotor, nacelle and tower and an energy output model based on the performance envelopes of the power coefficient of the rotor, C P , on the Weibull parameters k and c and on the power law coefficient α of the wind profile. In this study the site is defined with these three parameters and the extreme wind speed V max . The model parameters vary within a range of possible values. Other elements of the project (foundation, grid connection, financing cost, etc.) are taken into account through coefficients. The optimal values of the parameters are determined using genetic algorithms, which appear to be efficient for such a problem. These optimal values were found to be very different for a Mediterranean site and a northern European site using our numerical model. Optimal wind turbines at the Mediterranean sites considered in this article have an excellent profitability compared with reference northern European wind turbines. Most of the existing wind turbines appear to be well designed for northern European sites but not for Mediterranean sites. Copyright © 2001 John Wiley & Sons, Ltd.
A fluid flow tracking arbiter for input buffered ATM switch with heterogeneous port bandwidth (2004)

The problem of designing a weighted arbiter for an input buffered ATM switch with heterogeneous port bandwidths and which supports multiple classes of service is considered. A novel approach to design arbiters is proposed and illustrated with an application for a small (32 /spl times/ 32) input buffered ATM switch with two classes of services: the high priority guaranteed service class and a low priority overbookable service class. The GPS fairness criteria, which was proposed in A. K. Parekh and R. G. Gallager (June 1993) for service schedulers, is generalized for the arbitration problem and the proposed fluid flow tracking arbiter (FFTA) satisfies the fairness criteria. In the FFTA, the requests to the arbiter are treated both as discrete and as fluid quantities. The arbitration decisions are made by simulating a fluid flow of requests and grants are issued so as to minimize deviation of the discrete requests from their fluid counterparts.

Hydrophobic, transparent and hard silicon oxynitride coating from perhydropolysilazane (2015)

Abstract Silicon oxynitride coatings on glass and polyethylene terephthalate ( PET ) film have been fabricated by thermal annealing of inorganic polymer perhydropolysilazane ( PHPS ) between 60 °C and 200 °C. The chemical structure, thermal behavior and structural evolution of PHPS were investigated. The coatings obtained on glass possess pencil hardness as high as 9H , high transparency above 90% in the visible wavelength range, good adhesion to the substrate and a hydrophobic property with water contact angle above 98°. The PHPS coated PET film has pencil hardness above 4H , water contact angle 102° and a high scratch resistance property with no obvious scratches after a 50 cycles scratch test under a load of 2 kg. All these data imply the great potential of PHPS as a hard coating for optical devices. © 2015 Society of Chemical Industry
Surface/Chemically Modified LiMn[sub 2]O[sub 4] Cathodes for Lithium-Ion Batteries (2002)

spinel oxide has been surface/chemically modified with and MgO using a chemical processing procedure followed by heat-treatment at 300-800°C. The surface/chemically modified samples show much better capacity retention at both 25 and 60°C than does the unmodified (41% fade in 100 cycles at 60°C). Among the various compositions investigated, the -modified sample shows superior capacity retention with only 2.8% fade in 100 cycles at 60°C with around 110 mAh/g. The -modified sample shows a higher capacity of 130 mAh/g, but with a faster fade (16% in 100 cycles at 60°C). The -modified sample shows the best combination of capacity (124 mAh/g) and retention (8% fade in 100 cycles at 60°C). The modified samples also exhibit better capacity retention after aging at 55°C at 60-70% depth of discharge. © 2002 The Electrochemical Society. All rights reserved.
