Synthesis and reactions of Ru(CH<sub>2</sub>)Cl(NO)(PPh<sub>3</sub>)<sub>2</sub>, a stable terminal methylene complex and the crystal structure of Ru(CH<sub>2</sub>PPh<sub>3</sub>)(η<sup>2</sup>-C<sub>2</sub>F<sub>4</sub>)Cl(NO)(PPh<sub>3</sub>) (1991)

Treatment of RuCl(NO)(PPh3)2 with CH2N2 in diethyl ether at room temperature affords Ru(CH2)Cl(N)(PPh3)21. Complex 1 undergoes a reaction with each of the reagents HCl, [Aul2]–, HgCl(C6H4Me-p), HgCl2 and SO2 forming respectively RuMeCl2(NO)(PPh3)22, [graphic omitted]ul)Cl(NO)(PPh3)23, Ru[CH2Hg(C6H4Me-p)]Cl2(NO)(PPh3)24a, Ru(CH2HgCl)Cl2(NO)(PPh3)24b and [graphic omitted]]Cl(NO)(PPh3)25. Treatment of 1 with PhC2Ph at room temperature affords the unstable complex Ru(CH2PPh3)(η2-PhC2Ph)Cl(NO)(PPh3)6. Reaction of 1 with ethylene under the same conditions gives, as a final product, Ru(η2-C2H4)Cl(NO)(PPh3)211. An NMR investigation of the production of 11 confirmed the presence of the intermediate Ru(CH2PPh3)(η2-C2H4)Cl(NO)(PPh3)10, and the formation of propene as 11 was generated, suggesting a possible metallacyclopropane intermediate. In contrast, treatment of 1 with C2F4 yields Ru(CH2PPh3)(η2-C2F4)Cl(NO)(PPh3)7, exclusively, the structure of which was confirmed by single-crystal X-ray diffraction. The metal geometry is that of a distorted trigonal bipyramid, with the triphenylphosphine and the ylide carbon occupying the apical sites. The osmium analogue of 7, Os(CH2PPh3)(η2-C2F4)Cl(NO)(PPh3)8, is obtained from a similar reaction.
Geometry Compression for 3D Polygonal Models using a Neural Network (2010)

Three dimensional models are commonly used in computer graphics and 3D modeling characters in animation movies and games. 3D objects are more complex to handle than other multimedia data due to the fact that various representations exist for the same object, yielding a number of difficulties, among of which are the distinct sources of 3D data. Research work in the field of three dimensional environments is represented by a broad spectrum of applications. In this paper we restrict ourselves only on how to do compression using a neural network in order to minimize the size of 3D models for making transmission over networks much faster. The main objective behind this compression is to simplify the 3D model and make handling the large size of 3d objects much easier for other processes. Even the process of rendering, digital watermarking, etc., will be faster and more efficient.
Color Design for Illustrative Visualization (2008)

Professional designers and artists are quite cognizant of the rules that guide the design of effective color palettes, from both aesthetic and attention-guiding points of view. In the field of visualization, however, the use of systematic rules embracing these aspects has received less attention. The situation is further complicated by the fact that visualization often uses semi-transparencies to reveal occluded objects, in which case the resulting color mixing effects add additional constraints to the choice of the color palette. Color design forms a crucial part in visual aesthetics. Thus, the consideration of these issues can be of great value in the emerging field of illustrative visualization. We describe a knowledge-based system that captures established color design rules into a comprehensive interactive framework, aimed to aid users in the selection of colors for scene objects and incorporating individual preferences, importance functions, and overall scene composition. Our framework also offers new knowledge and solutions for the mixing, ordering and choice of colors in the rendering of semi-transparent layers and surfaces. All design rules are evaluated via user studies, for which we extend the method of conjoint analysis to task-based testing scenarios. Our framework's use of principles rooted in color design with application for the illustration of features in pre-classified data distinguishes it from existing systems which target the exploration of continuous-range density data via perceptual color maps.
Multiparametric 3T Prostate Magnetic Resonance Imaging to Detect Cancer: Histopathological Correlation Using Prostatectomy Specimens Processed in Customized Magnetic Resonance Imaging Based Molds (2011)

Prostate magnetic resonance imaging at 3T allows for the detection of prostate cancer. A multiparametric approach increases the predictive power of magnetic resonance imaging for diagnosis. In this study accurate correlation between multiparametric magnetic resonance imaging and histopathology was obtained by the patient specific, magnetic resonance imaging based mold technique.
Distributed Machine Learning in Coalition Environments: Overview of Techniques (2018)

Many modern applications generate a significant amount of data in dispersed geographical areas. To analyze and make use of the data, data fusion and machine learning techniques are usually applied, which has the potential to greatly enhance the amount of information extracted from the data. These algorithms traditionally run in data center environments where all the data are available at a central location. It is challenging to run them in distributed coalition environments, where it is impractical to send all the raw data to a single place due to bandwidth and security constraints. This problem has gained notable attention recently. In this paper, we provide an overview of available techniques and recent results of performing data fusion and machine learning in a distributed coalition environment, without sharing the raw data among local processing nodes. We discuss techniques for distributed model training, scoring, and outline some applications where these techniques are applicable and beneficial.
<i>Jekyll</i>Encodes a Novel Protein Involved in the Sexual Reproduction of Barley (2006)

Cereal seed development depends on the intimate interaction of filial and maternal tissues, ensuring nourishment of the new generation. The gene jekyll, which was identified in barley (Hordeum vulgare), is preferentially expressed in the nurse tissues. JEKYLL shares partial similarity with the scorpion Cn4 toxin and is toxic when ectopically expressed in Escherichia coli and tobacco (Nicotiana tabacum). In barley, jekyll is upregulated in cells destined for autolysis. The gene generates a gradient of expression in the nucellar projection, which mediates the maternal-filial interaction during seed filling. Downregulation of jekyll by the RNA interference technique in barley decelerates autolysis and cell differentiation within the nurse tissues. Flower development and seed filling are thereby extended, and the nucellar projection no longer functions as the main transport route for assimilates. A slowing down in the proliferation of endosperm nuclei and a severely impaired ability to accumulate starch in the endosperm leads to the formation of irregular and small-sized seeds at maturity. Overall, JEKYLL plays a decisive role in the differentiation of the nucellar projection and drives the programmed cell death necessary for its proper function. We further suggest that cell autolysis during the differentiation of the nucellar projection allows the optimal provision of basic nutrients for biosynthesis in endosperm and embryo.
Cost-effective bidirectional chopper-based battery link UPS with common input-output bus line and its control scheme (2002)

This paper presents a nonisolated prototype of an input-output common bus line UPS circuit topology using IGBT modules, which incorporates a bidirectional power converter circuit for battery bank interface, as well as its related-specific current-mode control strategy. The steady-state operating principle of the power conversion circuit system topologies and control strategy are described herein. Feasible experimental results of this cost-effective and high-performance UPS topology with a two-quadrant chopper-fed battery bank are illustrated for a 3 kVA UPS and discussed as compared with a conventional UPS with battery bank connected to an HVDC bus.
Vagus nerve stimulation decreases left ventricular contractility <i>in vivo</i> in the human and pig heart (2001)

1. Studies of the effect of vagus nerve stimulation on ventricular myocardial function in mammals are limited, particularly in the human. 2. The present study was designed to determine the effect of direct electrical stimulation of the left vagus nerve on left ventricular contractile state in hearts paced at 10 % above the natural rate, in anaesthetised pigs and anaesthetised human subjects undergoing open chest surgery for coronary artery bypass grafting. 3. Contractility of the left ventricle was determined from a series of pressure-volume loops obtained from a combined pressure and conductance (volume) catheter placed in the left ventricle. From the measurements a regression slope of the end-systolic pressure-volume relationship was determined to give end-systolic elastance (Ees), a load-independent measure of contractility. 4. In six anaesthetised open chest pigs, stimulation of the peripheral cut end of the left cervical vagus nerve induced a significant decrease in Ees of 26 +/- 14 %. 5. In nine patients electrical stimulation of the left thoracic vagus nerve close to its cardiac branch resulted in a significant drop in Ees of 38 +/- 16 %. 6. The effects of vagal stimulation were blocked by the muscarinic antagonist glycopyrronium (5 mg kg(-1)). 7. Administration of the beta-adrenoreceptor antagonist esmolol (1 mg kg(-1)) also attenuated the effect of vagal stimulation, indicating a degree of interaction of vagal and sympathetic influences on contractility. 8. These studies show that in the human and pig heart the left vagus nerve can profoundly decrease the inotropic state of the left ventricular myocardium independent of its bradycardic effect.
Toward high sequence coverage of proteins in human breast cancer cells using on‐line monolith‐based HPLC‐ESI‐TOF MS compared to CE MS (2006)

A method is developed toward high sequence coverage of proteins isolated from human breast cancer MCF10 cell lines using a 2-D liquid separations. Monolithic-capillary columns prepared by copolymerizing styrene with divinylbenzene are used to achieve high-resolution separation of peptides from protein digests. This separation is performed with minimal sample preparation directly from the 2-D liquid fractionation of the cell lysate. The monolithic column separation is directly interfaced to ESI-TOF MS to obtain a peptide map. The protein digests were also analyzed by MALDI-TOF MS and an accurate M(r) of the intact protein was obtained using an HPLC-ESI-TOF MS. The result is that these techniques provide complementary information where nearly complete sequence coverage of the protein is obtained and can be compared to the experimental M(r) value. The high sequence coverage provides information on isoforms and other post-translational modifications that would not be available from methods that result in low sequence coverage. The results from the use of monolithic columns are compared to that obtained by CE-MS. The monolithic column separations provide a rugged and highly reproducible method for separating protein digests prior to MS analysis and is suited to confidently identify biomarkers associated with cancer progression.
Human-Robot Interaction: Issues in the Design of Interfaces for Work in Distant Environments (2009)

The goal of technology tends to be to enhance and extend human capabilities. One purpose of robotics is to be able to work in a task environment that is distant from you, often because that distant environment is less safe and/or less accessible than your current environment. HRI must address a number of critical issues in order for human-robot system interfaces to be effective and efficient. The goal of this symposium is to identify selected critical interface issues and to provide conceptual/theoretical, empirical, and applied discussions of the interface-related issues in HRI.
Combined cDNA Array Comparative Genomic Hybridization and Serial Analysis of Gene Expression Analysis of Breast Tumor Progression (2006)

To identify genetic changes involved in the progression of breast carcinoma, we did cDNA array comparative genomic hybridization (CGH) on a panel of breast tumors, including 10 ductal carcinoma in situ (DCIS), 18 invasive breast carcinomas, and two lymph node metastases. We identified 49 minimal commonly amplified regions (MCRs) that included known (1q, 8q24, 11q13, 17q21-q23, and 20q13) and several uncharacterized (12p13 and 16p13) regional copy number gains. With the exception of the 17q21 (ERBB2) amplicon, the overall frequency of copy number alterations was higher in invasive tumors than that in DCIS, with several of them present only in invasive cancer. Amplification of candidate loci was confirmed by quantitative PCR in breast carcinomas and cell lines. To identify putative targets of amplicons, we developed a method combining array CGH and serial analysis of gene expression (SAGE) data to correlate copy number and expression levels for each gene within MCRs. Using this approach, we were able to distinguish a few candidate targets from a set of coamplified genes. Analysis of the 12p13-p12 amplicon identified four putative targets: TEL/ETV6, H2AFJ, EPS8, and KRAS2. The amplification of all four candidates was confirmed by quantitative PCR and fluorescence in situ hybridization, but only H2AFJ and EPS8 were overexpressed in breast tumors with 12p13 amplification compared with a panel of normal mammary epithelial cells. These results show the power of combined array CGH and SAGE analysis for the identification of candidate amplicon targets and identify H2AFJ and EPS8 as novel putative oncogenes in breast cancer.
Improved Hydrogen Storage in the Metal‐Organic Framework Cu<sub>3</sub>(BTC)<sub>2</sub> (2006)

A new pressure‐free synthesis method was developed producing the porous material Cu 3 (BTC) 2 (BTC = benzene tricarboxylate) with a very high micropore volume up to 0.62 cm 3 g –1 . The compound is a promising nanoporous solid for adsorptive hydrogen storage under cryogenic conditions with a capacity of 2.18 wt% which is higher than that of IRMOFs and other coordination polymers.
The Analysis of 3D Printer Dust for Forensic Applications,, (2020)

3D printers are becoming increasingly efficient and economical, and thus more widespread and easily accessible to consumers and businesses. They have been used to print nefarious objects such as guns and suppressors. Previous research has documented the release of dust particles during the printing process; however, little has been written about the morphology and chemical features that define the dust emitted by these printers. This study was undertaken to recover, analyze, and identify the dust produced during the printing process in the context of forensic trace evidence analysis. Samples were collected from a variety of 3D fused deposition modeler printers, representing both consumer and commercial grade models. This work focused on printers that use thermoplastic filaments composed of acrylonitrile butadiene styrene (ABS) or polylactic acid (PLA), two of the most commonly used filament polymers. Swabs were used to collect dust within the printer chamber and then processed to isolate the dust particles. Particles produced from ABS filaments are most easily recognized via light microscopy through a combination of color, morphology, and fluorescence. The composition of these particles can be confirmed through analysis by either FTIR or Raman microspectroscopy. These methods can also be used to identify ABS fillers and pigments within the printer dust particles. In contrast, dust from PLA printers consistently contained finer, submicron-sized particles that could be observed by field emission scanning electron microscopy. Because the size of the particles precludes their identification using vibrational spectroscopy methods, pyrolysis-GC-MS was used to confirm the presence of PLA.
AlN thin films grown on epitaxial 3C–SiC (100) for piezoelectric resonant devices (2010)

Highly c-axis oriented heteroepitaxial aluminum nitride (AlN) films were grown on epitaxial cubic silicon carbide (3C–SiC) layers on Si (100) substrates using alternating current reactive magnetron sputtering at temperatures between approximately 300–450 °C. The AlN films were characterized by x-ray diffraction, scanning electron microscope, and transmission electron microscopy. A two-port surface acoustic wave device was fabricated on the AlN/3C–SiC/Si composite structure, and an expected Rayleigh mode exhibited a high acoustic velocity of 5200 m/s. The results demonstrate the potential of utilizing AlN films on epitaxial 3C–SiC layers to create piezoelectric resonant devices.
Effects of Pasteurella multocida Endotoxins on Turkey Poults (1987)

Studies of turkey poult responses to Pasteurella multocida endotoxins indicated that lipopolysaccharide (LPS) preparations from two highly pathogenic strains and free endotoxin from one of these strains were all similar in lethal toxicity. Lethal intravenous doses were generally high, 1 mg or more for 1-week-old poults (13.3 mg/kg). The toxic effects of LPS were not increased by repeated administration of small hourly doses. For both forms of endotoxin, the relationship between dose and response was considered erratic. Attempts to increase the susceptibility of poults to LPS by administering a liver-damaging substance (galactosamine) or a histamine-releasing substance (compound 48/80) or by performing surgical bursectomy were not effective. The LPS did not provoke a dermal Shwartzman reaction, even though doses used were 10 times those that produced a characteristic reaction in a rabbit.
The Landscape of Prognostic Outlier Genes in High-Risk Prostate Cancer (2015)

To our knowledge, this study represents the first unbiased high-throughput investigation of prognostic outlier genes in prostate cancer and demonstrates the potential biomarker and therapeutic importance of this previously unstudied class of cancer genes.
Liquid-Phase Gallium–Indium Alloy Electronics with Microcontact Printing (2013)

Liquid-phase electronic circuits are patterned on an elastomer substrate with a microcontact printer. The printer head dips into a pool of a liquid-phase gallium-indium alloy, e.g., eutectic gallium-indium (EGaIn) or gallium-indium-tin (Galinstan), and deposits a single drop on a silicone elastomer substrate. After patterned deposition, the liquid-phase circuit is sealed with an additional layer of silicone elastomer. We also demonstrate patterned deposition of the liquid-phase GaIn alloy with a molded polydimethylsiloxane stamp that is manually inked and pressed into an elastomer substrate. As with other liquid-phase electronics produced through needle injection or masked deposition, the circuit is elastically deformable and can be stretched to several times its natural length without losing electronic functionality. In contrast to existing fabrication techniques, microcontact printing and stamp lithography can be used to produce circuits with any planar geometric feature, including electrodes with large planar area, intersecting and closed-loop wires, and combs with multiple terminal electrodes. In air, the surface of the coalesced droplets oxidize to form a thin oxide skin that preserves the shape of the circuit during sealing. This first demonstration of soft-lithography fabrication with liquid-phase GaIn alloy expands the space of allowable circuit geometries and eliminates the need for mold or mask fabrication.

The regulation of human factor XIIa by plasma proteinase inhibitors. (1985)

Studies of the inactivation of factor XIIa by plasma protease inhibitors in purified systems and in plasma were initiated to determine the relative importance of these inhibitors to the neutralization of factor XIIa. Factor XIIa was measured by the amidolysis of H-D-prolyl-L-phenylalanyl-L-arginine-p-nitroanilide dihydrochloride or by coagulant activity. C1 inhibitor (C1INH), alpha 2-antiplasmin (alpha 2AP), alpha 2-macroglobulin (alpha 2M), and antithrombin III (ATIII) inhibited factor XIIa with second-order rate constants of 2.2 X 10(5), 1.1 X 10(4), 5.0 X 10(3), and 1.3 X 10(3) M-1 min-1. Factor XIIa activity was not affected by alpha 1-proteinase inhibitor. Incubation of 125I-radiolabeled factor XIIa resulted in 1:1 stoichiometric complexes with C1INH (Mr 190,000), ATIII (Mr 125,000), and alpha 2AP (Mr 150,000 and 125,000) using sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Incubation of 125I-Factor XIIa with alpha 2M resulted in a component of Mr 85,000 on a reduced sodium dodecyl sulfate-polyacrylamide gel, indicating that a subunit of factor XIIa was covalently bound to a proteolyzed portion of alpha 2M. The relative effectiveness of each inhibitor at plasma concentrations was 61:2:3:1 for C1INH, alpha 2AP, alpha 2M, and ATIII, respectively. Kinetic studies of the inactivation of purified factor XIIa added to various plasmas containing different concentrations of C1INH verified the predictions from the purified systems. Gel filtration of radiolabeled factor XIIa incubated with plasma confirmed that factor XIIa-C1INH was the major complex. Analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis indicated that the complexes in plasma had the same molecular size as those with purified inhibitors. C1INH functions as the predominant inhibitor of factor XIIa in plasma.
A New Technique of Deformation Measurements Based on Microwave Resonant Cavities. (1980)

Difficulties with conventional extensometers have led to the development of a new experimental technique to study the behaviour of pre-stressed concrete at cryogenic temperatures. A specially designed coaxial cavity is used as a transducer which relates linearly relative changes in gauge length to relative changes in resonant frequency. An accompanying instrument that automatically measures and displays the resonant frequency of the cavity with sufficient accuracy has also been constructed. This technique has potential applications in more conventional, room temperature civil engineering measurements.
A coherent detection system with a suppressed pilot channel for ds/cdma systems (1996)

Abstract This paper proposes a coherent detection system using a suppressed pilot channel to achieve coherent RAKE diversity combining for DS/CDMA up‐link in land mobile communication systems. At the receiver, delay profile is measured using the suppressed pilot channel and simultaneously chip timing is detected by using block demodulation and maximum likelihood estimation, and measured the complex delay profile. The performance of proposed adaptive RAKE diversity is evaluated by computer simulation for quadriphase‐shift keying (QPSK) system. The results show that the performance of the proposed scheme is superior to that of the conventional DPSK/PDI, and it is almost the same as the theoretical performance for the coherent RAKE diversity receivers.
