Towards the Automation of the Service Composition Process: Case Study and Prototype Implementations (2008)

Service Composition has been a challenging research area for many years. One of the key ideas in this area is the matchmaking (at the semantic level) of requested services and the portfolio of services registered in a given service repository. Accordingly, a composite service can be generated by selecting a set of existing service components that partially match the requested service, and composing these services. In this paper we introduce a general framework for the Service Composition process and our efforts to automate this process. This framework exploits the semantic annotation of services and their parameters. The main annotations we focus on are service inputs, outputs, goals, preconditions, effects, and non-functional properties. Matchmaking aims at making sure that the selected service components are capable of interacting with each other, while the composition aims at orchestrating the selected service components to fulfil the goals of the service request. The framework takes care of service requests from both experienced service developers as well as ordinary end-users who are not necessarily familiar with service concepts and platforms. Three main prototype platforms have been developed to experiment with the framework.
Cell density modulates growth, extracellular matrix, and protein synthesis of cultured rat mesangial cells. (1993)

Mesangial cell (MC) hyperplasia and accumulation of extracellular matrix are hallmarks of chronic glomerular disease. The present in vitro study examined the effects of cell density on growth, extracellular matrix formation, and protein synthesis of cultured rat MCs. A negative linear relationship was found between initial plating density and DNA synthesis per cell after 24 hours incubation in medium with 10% fetal calf serum (range: 1 x 10(3) to 7 x 10(5) MCs/2cm2, r = 0.996, P < 0.001). Enzyme-linked immunosorbent assay of the amount of fibronectin in the conditioned medium after 72 hours showed a negative relationship with increasing cell density. In contrast, the amount of cell-associated fibronectin increased to maximal values in confluent cultures, and no further increase was seen at supraconfluency. The relative collagen synthesis in the conditioned medium and cell layer--assessed by collagenase digestion after 5 hours [3H]proline pulse labeling--showed a similar pattern. Secreted collagen decreased with increasing cell density from 3.4% to 0.2% of total protein synthesis. In contrast, cell-associated collagen increased from 1.1% to 11.8% of newly synthesized protein until confluency followed by a decrease to 4.2% at supraconfluency. Specific immunoprecipitation of collagen types I, III, and IV revealed a significant (twofold) increase in collagen I synthesis per cell at confluency. Collagen III and IV synthesis was not affected by cell density. Specific protein expression in both the medium and cell layer were analyzed by two-dimensional polyacrylamide gel electrophoresis (150 to 20 kd, pI 5.0 to 7.0) after 20 hours steady-state metabolic labeling with [35S]methionine. Supraconfluent MCs displayed overexpression of 10, underexpression of four, new expression of five, and changed mobility of three different intracellular proteins. Of interest was the overexpression of two proteins (89 kd, pI 5.31 and 72 kd, pI 5.32) that were identified by immunoblotting as the stress proteins heat-shock protein 90 and glucose-related protein 78, respectively. The progressive increase of cell-associated fibronectin and collagens, particularly collagen type I, in confluent MCs resembles extracellular matrix accumulation in glomerular disease. The increased expression of stress proteins in supraconfluent MCs is of interest in view of the analogy between glomerulosclerosis and atherosclerosis in which stress proteins are expressed in high concentrations.
Optimization of Differential Display of Prokaryotic mRNA: Application to Pure Culture and Soil Microcosms (1998)

The differential display (DD) technique, which is widely used almost exclusively for eukaryotic gene discovery, was optimized to detect differential mRNA transcription from both pure-culture and soil-derived bacterial RNA. A model system which included toluene induction of todC1 in Pseudomonas putida F1 was used to optimize the procedure. At 24-h tod induction was determined to be approximately 8 x 10(7) transcripts/microg or 0.08% of the total mRNA. The primer concentration, primer length, annealing temperature, and template, deoxynucleoside triphosphate, and MgCl2 concentrations were varied to optimize amplification of a todC1 fragment. The limit of detection of todC1 by DD was found to be 0.015 ng of total RNA template or approximately 10(3) transcripts. Once optimized, a todC1C2 gene fragment from P. putida F1 RNA was detected by using an arbitrary primer for the reverse transcriptase step in conjunction with the same arbitrary primer and a Shine-Dalgarno primer in the PCR. To verify the results, an arbitrary primer was used to detect recovery of a new salicylate-inducible naphthalene dioxygenase in Burkholderia cepacia JS150. The method was then used to detect mRNA induction in both inoculated and uninoculated toluene-induced soil microcosms. Several putative differentially expressed partial gene sequences obtained from the uninoculated microcosms were examined, and one novel fragment was found to be differentially expressed.
Infrared Photodetection Based on Colloidal Quantum-Dot Films with High Mobility and Optical Absorption up to THz (2016)

Infrared thermal imaging devices rely on narrow band gap semiconductors grown by physical methods such as molecular beam epitaxy and chemical vapor deposition. These technologies are expensive, and infrared detectors remain limited to defense and scientific applications. Colloidal quantum dots (QDs) offer a low cost alternative to infrared detector by combining inexpensive synthesis and an ease of processing, but their performances are so far limited, in terms of both wavelength and sensitivity. Herein we propose a new generation of colloidal QD-based photodetectors, which demonstrate detectivity improved by 2 orders of magnitude, and optical absorption that can be continuously tuned between 3 and 20 μm. These photodetectors are based on the novel synthesis of n-doped HgSe colloidal QDs whose size can be tuned continuously between 5 and 40 nm, and on their assembly into solid nanocrystal films with mobilities that can reach up to 100 cm(2) V(-1) s(-1). These devices can be operated at room temperature with the same level of performance as the previous generation of devices when operated at liquid nitrogen temperature. HgSe QDs can be synthesized in large scale (>10 g per batch), and we show that HgSe films can be processed to form a large scale array of pixels. Taken together, these results pave the way for the development of the next generation mid- and far-infrared low-cost detectors and camera.
"Silicon Drift Devices for Track and Vertex Detection at the SSC" (1990)

We report on the recent progress in the study of Semiconductor Drift (Memory) Detectors intended for an inner tracking and vertexing system for the SSC.

Pan-STARRS: A Large Synoptic Survey Telescope Array (2002)

The IFA and collaborators are embarking on a project to develop a 4-telescope synoptic survey instrument. While somewhat smaller than the 6.5m class telescope envisaged by the decadal review in their proposal for a LSST, this facility will nonetheless be able to accomplish many of the LSST science goals. In this paper we will describe the motivation for a 'distributed aperture' approach for the LSST, the current concept for Pan-STARRS -- a pilot project for the LSST proper -- and its performance goals and science reach. We will also discuss how the facility may be expanded.

Is There a Role for Gastric Accommodation and Satiety in Asymptomatic Obese People? (2001)

Asymptomatic obese individuals (within the BMI range of 32.6 to 48 kg/m(2)) did not show either increased postprandial gastric accommodation or reduced satiety. These data suggest that gastric accommodation is unlikely to provide an important contribution to development of moderate obesity.
Fluorescent Micelles Based on Star Amphiphilic Copolymer with a Porphyrin Core for Bioimaging and Drug Delivery (2011)

Star-shaped poly(ε-caprolactone)-b-poly(ethylene oxide) amphiphilic copolymer with a tetrakis-(4-aminophenyl)-terminated porphyrin core was synthesized. Paclitaxel (PTX)-loaded polymeric micelles were prepared by the self-assembly of the star copolymer and in situ encapsulation of PTX. The fluorescent characteristic of the porphyrin moiety allowed the cellular uptake and biodistribution of the PTX-loaded micelles to be monitored by fluorescent imaging. The PTX-loaded micelles can be readily internalized by cancer cells and have a slightly higher cytotoxicity than clinic PTX injection Taxol. In vivo real-time fluorescent imaging revealed that the micelles could accumulate at tumor site via the blood circulation in tumor-bearing mice. In vivo antitumor efficacy examinations indicated that the PTX-loaded micelles had significantly superior efficacy in impeding tumor growth than Taxol and low toxicity to the living mice.
Synthesis and central nervous system actions of thyrotropin-releasing hormone analog containing a dihydroorotic acid moiety (1990)

A series of thyrotropin-releasing hormone (TRH) analogues in which the pyroglutamic acid residue was replaced by (S)-4,5-dihydroorotic acid (Dio-OH) and the related derivatives were prepared. Their central nervous system actions based on spontaneous locomotor activity, antagonistic effect on reserpine-induced hypothermia, and antagonistic effect on pentobarbital anesthesia were evaluated and the structure-activity relationships are discussed. Of these, (1-methyl-(S)-4,5-dihydroorotyl)-L-histidyl-L-prolinamide (14b) showed the most potent activities, which were 30-90 times greater than those of TRH. Moreover, the thyrotropin-releasing activity of 14b was about 50 times weaker than that of TRH, and compound 14b (TA-0910) was selected as a potent candidate.
Fractions of lipopolysaccharide from Escherichia coli O111:B4 prepared by two extraction procedures. (1975)

Lipopolysaccharides have been extracted from Escherichia coli O111:B4 by phenol extraction and by a new method employing aqueous butanol. Both methods yield very similar lipopolysaccharide preparations. Gel filtration chromatography of either preparation yields two physically and chemically distinct lipopolysaccharide fractions. One fraction contains lipopolysaccharide molecules with long antigenic side chains. It acts like a highly asymmetric unit with an apparent weight of 1.5 times 10-6 and is not dissociated by detergents or deacylation. The second fraction has a short antigenic side chain and can be dissociated by sodium dodecyl sulfate and Triton X-100 into units of approximately 90,000. Some properties of the lipopolysaccharide fractions vary with the method of extraction.
Efficient compilation of fine-grained SPMD-threaded programs for multicore CPUs (2010)

In this paper we describe techniques for compiling fine-grained SPMD-threaded programs, expressed in programming models such as OpenCL or CUDA, to multicore execution platforms. Programs developed for manycore processors typically express finer thread-level parallelism than is appropriate for multicore platforms. We describe options for implementing fine-grained threading in software, and find that reasonable restrictions on the synchronization model enable significant optimizations and performance improvements over a baseline approach. We evaluate these techniques in a production-level compiler and runtime for the CUDA programming model targeting modern CPUs. Applications tested with our tool often showed performance parity with the compiled C version of the application for single-thread performance. With modest coarse-grained multithreading typical of today's CPU architectures, an average of 3.4x speedup on 4 processors was observed across the test applications.
Anti-cancer activity of nitrones in the<i>Apc</i><sup>Min/+</sup>model of colorectal cancer (2009)

Abstract The nitrones of alpha-phenyl-tert-butyl nitrone (PBN) and 4-hydroxyl-PBN (4-OH-PBN) that have anti-cancer activity in models of liver cancer and glioblastomas were tested in the ApcMin/+ mouse model. Mice were administered PBN and 4-OH-PBN in drinking water and intestinal tumour size and number assessed after 3-4 months. Throughout the experiment, contrast-enhanced magnetic resonance imaging (MRI) was used to monitor colon tumours. MRI data showed a time-dependent significant increase in total colonic signal intensity in sham-treated mice, but a significant decrease for PBN-treated mice and slight decrease for 4-OHPBN treated mice, probably due to the limited water solubility of 4-OH-PBN. Final pathological and percentage survival data agreed with the MRI data. PBN had little effect on oxaliplatin-mediated killing of HCT116 colon cancer cells and caused only a slight decrease in the amount of active fraction caspase 3 in oxaliplatin-treated cells. PBN has significant anti-cancer activity in this model of intestinal neoplasia.

A machine for the automatic analysis of human blood and other body fluids is described. Brief reference is made to the associated biochemistry. The problems of measurement of sample optical density and the control of sample temperature, are discussed, and the considerations leading to the choice of photo-cells for the analysers are considered. The analysing equipment and the means of achieving positive identification of samples are described. The requirements for controlling the machine are discussed and the application of computer-control to the machine and the logging of output data is described.
Applications of Continuous-Flow Photochemistry in Organic Synthesis, Material Science, and Water Treatment (2016)

Continuous-flow photochemistry in microreactors receives a lot of attention from researchers in academia and industry as this technology provides reduced reaction times, higher selectivities, straightforward scalability, and the possibility to safely use hazardous intermediates and gaseous reactants. In this review, an up-to-date overview is given of photochemical transformations in continuous-flow reactors, including applications in organic synthesis, material science, and water treatment. In addition, the advantages of continuous-flow photochemistry are pointed out and a thorough comparison with batch processing is presented.
Film Synthesis of Y <sub>3</sub> Al <sub>5</sub> O <sub>12</sub> and Y <sub>3</sub> Fe <sub>5</sub> O <sub>12</sub> by the Spray–Inductively Coupled Plasma Technique (2001)

Thin films of yttrium aluminum garnet (YAG, Y 3 Al 5 O 12 ) and yttrium iron garnet (YIG, Y 3 Fe 5 O 12 ) were synthesized on single‐crystal Al 2 O 3 substrates by a modification of spray pyrolysis using a high‐temperature inductively coupled plasma at atmospheric pressure (spray–ICP technique). Using this technique, films could be grown at faster rates (0.12 μm/min for YAG and 0.10 μm/min for YIG) than using chemical vapor deposition (0.005–0.008 μm/min for YAG) or sputtering (0.003–0.005 μm/min for YIG). The films were dense and revealed a preferred orientation of (211). The growth of YIG was accompanied by coprecipitation of α‐Fe 2 O 3 . The coprecipitation, however, could be largely suppressed by preliminary formation of a Y 2 O 3 layer on the substrate.
Transmission considerations for polarization-smart antennas (2002)

Field trials in the wireless 1900 MHz band revealed that the averaged-in-time polarization measurements of the received wave is copolarized with the original transmitted polarization of the wave, and is highly correlated over a substantial frequency bandwidth. The polarization smart-antenna transmitter is realized at the base transceiver-station (BTS), and is based on the above trial results. In performing the polarization matching algorithm, the appropriate transmit polarization is matched to the averaged receive polarization, for each individual radio link (i.e. per each mobile station-MS), and is maintained dynamically. This recovers a substantial part of the polarization shadow link losses, and serves to reduce the forward power control variation and the average transmit power of the base station, as well as the induced self-interference. This paper discusses several BTS transmission architectures for the implementation of polarization-matching and presents quantitative power overloading, power efficiency and relative interference performance results per each configuration. Finally, an optimal architecture is presented for a multi-user polarization smart-antenna transmitter.
Electron microscopy investigation of structural transformations in tungsten oxide (WO<sub>3</sub>) thin films (2005)

Abstract The phase transformations in tungsten oxide (WO 3 ) thin films have been investigated in the temperature range of 30–500 °C using transmission electron microscopy (TEM) and selected area electron diffraction (SAED) measurements. The results indicate that the phase transitions in WO 3 thin films occur in sequence exhibiting various crystal phases above room temperature in the order: monoclinic → orthorhombic → hexagonal. The crystallographic distortions and tilting of the WO 6 octahedra are responsible for the phase transitions and significantly affect the electronic properties and, hence, the device applications of WO 3 .

An Object Recognition System for Complex Imagery that Models the Probability of a False Positive (1996)

This paper describes an object recognition system for use in complex imagery that can perform recognition adaptively by setting the matching threshold such that the probability of a false positive is low. In order to accurately model small, irregularly shaped objects, we represent the objects using dense sets of edge pixels with associated local orientations. Three-dimensional objects are modeled by a set of two-dimensional views of the object. We allow translation, rotation, and scaling of the views to approximate full three-dimensional motion of the object. We use a version Hausdorff measure to determine which positions of an object model are good matches to an image. These positions are determined efficiently through the examination of a hierarchical cell decomposition of the transformation space, which allows large volumes of the space to be pruned quickly. Additional techniques are used to decrease the computation time of the method when matching is performed against a catalog of ...
Silicon Photonics in Optical Coherent Systems (2018)

Investigation of collision‐induced dissociations involving odd‐electron ion formation under positive electrospray ionization conditions using accurate mass (2010)

Collision induced dissociation (CID) has been extensively used for structure elucidation. CID in the electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) modes has been found to generate mostly even-electron fragment ions while it has been occasionally reported to form odd-electron free radical ions. However, the structural requirements and the fragmentation mechanisms for free-radical CIDs have not been well characterized in the literature. For this purpose, we studied a series of aromatic and non-aromatic compounds such as sulfonamides, N-aryl amides, tert-butyl-substituted aromatic compounds, aryl alkyl ethers, and O-alkyl aryl oximes using the LTQ and LTQ Orbitrap linear ion trap mass spectrometers. The accurate measurement of the fragment ion masses established the unambiguous assignment of the fragment structures resulting from the test compounds. Our results showed that free radical fragmentation is structure dependent and is to a large extent correlated with the neighboring groups in the structures that stabilize the newly formed free radical ions.
Design and demonstration of a miniature catheter for a confocal microendoscope (2004)

The fluorescence confocal microendoscope provides high-resolution, in vivo imaging of cellular pathology during optical biopsy. The confocal microendoscope employs a flexible fiber-optic catheter coupled to a custom-built slit-scan confocal microscope. The catheter consists of a fiber-optic imaging bundle linked to a miniature objective and focus assembly. The 3-mm-diameter catheter may be used on its own or routed though the instrument channel of a commercial endoscope, adding microscopic imaging capability to conventional endoscopy. The design and performance of the miniature objective and focus assembly are discussed. Primary applications of the system include diagnosis of disease in the gastrointestinal tract and female reproductive system.
Coding for two-way channels (1961)

When time-variant noisy two-way channels are protected by coding, they may be used to provide essentially noiseless feedback, with delay. Service messages can be automatically exchanged between terminals, and transmission altered in such a way that the average communication rate is increased, given fixed receiver computers. The system is somewhat similar to human communication, in that typical errors are corrected, while grievous ones initiate a request for retransmission. One-way experimental data are presented to complement the approximate theoretical analysis. (Author)
