Rare Sandwich-Type Polyoxomolybdates Constructed from Di-/Tetra-Nuclear Transition-Metal Clusters and Trivacant Keggin Germanomolybdate Fragments (2009)

Two types of rare sandwich-type germanomolybdates [Na(12)(H(2)O)(36)][Cu(2)(beta-Y-GeMo(9)O(33))(2)].3H(2)O (1), [N(CH(3))(4)](4) [Na(6)(H(2)O)(24)][Cr(2)(beta-Y-GeMo(9)O(33))(2)].7H(2)O (2), and [Na(11)(H(2)O)(25)]H[M(4)(H(2)O)(2)(alpha-B-GeMo(9)O(34))(2)].6H(2)O (M = Ni(II) for 3, M = Mn(II) for 4 and M = Co(II) for 5) have been synthesized and characterized by elemental analyses, ICP spectra, IR spectroscopy, UV spectroscopy, thermogravimetry (TG) analyses (for 1-3), X-ray photoelectron spectroscopy (XPS) (for 1 and 3), X-ray powder diffraction (XRPD) (for 1 and 3) and single-crystal X-ray diffraction. To our knowledge, 1-5 represent the first sandwich-type germanomolybdates containing both {beta-Y-GeMo(9)O(33)}/{alpha-B-GeMo(9)O(34)} fragments and transition-metal clusters. Interestingly, 1 and 2 display the rare dinuclear transition-metal substituted sandwich-type structures with unusual trivacant {beta-Y-GeMo(9)O(33)} germanomolybdate units whereas 3-5 exhibit the first tetranuclear transition-metal substituted sandwich-type structures with familiar trivacant {alpha-B-GeMo(9)O(34)} germanomolybdate units. Surface photovoltage spectroscopy (SPS) and electric field induced surface photovoltage spectroscopy (EFISPS) measurements reveal that 1 and 3 bear the behavior of the n-type semiconductor. Magnetic measurements indicate 1 and 3 demonstrate antiferromagnetic exchange interactions and ferromagnetic exchange interactions, respectively.
A multiplexer employing Josephson functional gates (1985)

A new Josephson multiplexer is designed and analyzed. Experimentally, the multiplexer is fabricated by standard Pb alloy technology with 5-µm line width, and its operation is successfully performed. The typical operating margin is ±16 percent for the gate current. The multiplexer is a four-way multiplexer with a 2-4 decoder consisting of functional AND gates. The functional gates are composed of two asymmetric logics arranged in a series on its gate current line. These gates realize 2-4 decoder and data selector functions. The multiplexer offers advantages of integrated-circuit area reduction, low power dissipation, and high-speed operation.
Ultracompact TM-Pass Silicon Nanophotonic Waveguide Polarizer and Design (2010)

An ultracompact transverse magnetic (TM)-pass polarizer based on silicon nanophotonic waveguides is proposed, which contains two tapered waveguides sandwiching a narrow waveguide section only supporting TM-mode propagation. A full-vectorial eigenmode solver is employed to determine the appropriate cross section of the silicon nanophotonic waveguide. The device is first designed in a 2-D approximate model using a wide-angle beam propagation method, and numerical verification is carried out afterward using a parallel full-vectorial 3-D finite-difference time-domain simulation. Both approaches indicate that the finite thickness of the buried SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> layerand the reflection at the substrate play important roles on the extinction ratio of the device. A designed numerical example shows an extinction ratio of ~26 dB for the waveguide polarizer with a length of ~10 ¿m, while the insertion loss for the TM mode is negligible.
Joint optimization of relay selection and power allocation in cooperative wireless networks (2008)

In cooperative wireless networks, it is often the case that multi-source and multi-relay cooperate to transmit their own data to the destination, namely, the access point. For the cooperative systems, the choice of relay and the allocation of power between the source and the relay are important design issues. In this paper, based on the optimal power allocation between one source and one relay under an outage constraint, the joint optimization of relay selection and power allocation is done efficiently by introducing a greedy and exchange algorithm (GAEA), which aims at minimizing the total transmission power in the multi-source and multi-relay wireless networks where one relay can only be allocated to one source. Simulation results and numerical analyses show that, the proposed algorithm, with low computational complexity, can achieve the similar performance as the exhaustive search algorithm and save transmission power significantly.
Prevalence of ICA and GAD Antibodies at Initial Presentation of Type 1 Diabetes Mellitus in Singapore Children (2001)

Prevalence of antibodies at presentation of DM in Singapore (41.5%) is lower than in Caucasian populations (60-90%). Other autoantibodies yet to be identified may be contributory. Alternatively, non-immune mediated mechanisms may be responsible for a significant proportion of type 1 DM in Singapore children.
Novel Derivatives of Benzo[<i>b</i>]thieno[2,3-<i>c</i>]quinolones:  Synthesis, Photochemical Synthesis, and Antitumor Evaluation (2003)

Novel derivatives of benzo[b]thieno[2,3-c]quinolones 3a-j were synthesized in a multistep synthesis starting from substituted benzo[b]thiophene-2-carbonyl chlorides, to their corresponding benzo[b]thiophene-2-carboxamides, which were photochemically dehydrohalogenated to their corresponding substituted benzo[b]thieno[2,3-c]quinolones. Compound 4 was prepared from 3i by alkylation with 3-dimethylaminopropyl chloride in the presence of NaH. Compounds 7a,b were prepared from 3g in the multistep synthesis from compounds 5 and 6. Compounds 3b, 3c-f, 3h, 7a, and 7b were found to exert cytostatic activity against malignant cell lines: pancreatic carcinoma (MiaPaCa2), breast carcinoma (MCF7), cervical carcinoma (HeLa), laryngeal carcinoma (Hep2), colon carcinoma (CaCo-2), melanoma (HBL), human fibroblast cell lines (WI-38). The compounds that bear a 3-dimethylaminopropyl substituent on the quinolone nitrogen (3b, 3c-f, 3h) showed higher antitumor activity than compounds bearing the same substituent on the amidic nitrogen (7a and 7b). The compound 3h, which has a 3-dimethylaminopropyl substituent on the quinolone nitrogen and a methoxycarbonyl substituent at position 9, had marked antitumor activity. Because of strong cytotoxic effect of compound 4 on melanoma cells (HBL, ME 67.3, and ME 67.1), a potential mechanism of action was examined. Analysis of DNA and Annexin-V-FLUOS staining indicated that compound 4 causes cell death by apoptosis.

Stability of wild‐type and mutant RTEM‐1 β‐lactamases: Effect of the disulfide bond (1987)

Uniquely among class A beta-lactamases, the RTEM-1 and RTEM-2 enzymes contain a single disulfide bond between Cys 77 and Cys 123. To study the possible role of this naturally occurring disulfide in stabilizing RTEM-1 beta-lactamase and its mutants at residue 71, this bond was removed by introducing a Cys 77----Ser mutation. Both the wild-type enzyme and the single mutant Cys 77----Ser confer the same high levels of resistance to ampicillin in vivo to Escherichia coli; at 30 degrees C the specific activity of purified Cys 77----Ser mutant is also the same as that of the wild-type enzyme. Also, neither wild-type enzyme nor the Cys 77----Ser mutant is inactivated by brief exposure to p-hydroxymercuribenzoate. However, above 40 degrees C the mutant enzyme is less stable than wild-type enzyme. After introduction of the Cys 77----Ser mutation, none of the double mutants (containing the second mutations at residue 71) confer resistance to ampicillin in vivo at 37 degrees C; proteins with Ala, Val, Leu, Ile, Met, Pro, His, Cys, and Ser at residue 71 confer low levels of resistance to ampicillin in vivo at 30 degrees C. The use of electrophoretic blots stained with antibodies against beta-lactamase to analyze the relative quantities of mutant proteins in whole-cell extracts of E. coli suggests that all 19 of the doubly mutant enzymes are proteolyzed much more readily than their singly mutant analogues (at Thr 71) that contain a disulfide bond.(ABSTRACT TRUNCATED AT 250 WORDS)
Injection de glaçons de deutérium dans le tokamak TFR (1985)

Il est necessaire d’alimenter en combustible le cœur du plasma d’un reacteur thermonucleaire ; la seule methode possible pour y parvenir semble etre l’injection a grande vitesse de grains de deuterium solide (glacons). Les donnees theoriques, techniques, et experimentales existant sur le sujet sont presentees. L’experience realisee sur le tokamak TFR a confirme que cette methode est possible techniquement ; un injecteur fonctionnant sur un nouveau principe est presente. Elle est aussi possible physiquement sans deterioration du confinement. L’etude des phenomenes transitoires pendant l’injection s’est averee etre un moyen efficace d’analyse du transport de matiere et d’energie dans la decharge, en particulier, un phenomene de transport rapide, analogue a celui observe lors des disruptions, a ete etudie en details. Des conclusions concernant les disruptions en sont tirees.
A Multilevel DC to Three-Phase AC Architecture for Photovoltaic Power Plants (2018)

This paper presents a photovoltaic (PV) inverter architecture composed of stackable dc to three-phase ac converter blocks. Several such blocks, each containing a converter power stage and controls, are connected in series on their ac sides to obtain transformerless medium-voltage ac interfaces for PV power plants. The series-connected structure is made possible by a quadruple active bridge dc-dc converter that provides isolation between the PV input and each of the three ac-side phases within each block. Furthermore, since incoming PV power is transferred as constant balanced three-phase ac power, instantaneous input-output power balance bypasses the need for bulk energy storage. To streamline implementation and maximize system scalability and resilience, decentralized block-level controllers accomplish dc-link voltage regulation, maximum power point tracking, and ac-side power sharing without centralized means. The proposed architecture is validated by simulations of a PV string to medium-voltage ac system consisting of six blocks and on a proof-of-concept hardware prototype that consists of three cascaded converter blocks.
Robust text-independent speaker identification using Gaussian mixture speaker models (1995)

This paper introduces and motivates the use of Gaussian mixture models (GMM) for robust text-independent speaker identification. The individual Gaussian components of a GMM are shown to represent some general speaker-dependent spectral shapes that are effective for modeling speaker identity. The focus of this work is on applications which require high identification rates using short utterance from unconstrained conversational speech and robustness to degradations produced by transmission over a telephone channel. A complete experimental evaluation of the Gaussian mixture speaker model is conducted on a 49 speaker, conversational telephone speech database. The experiments examine algorithmic issues (initialization, variance limiting, model order selection), spectral variability robustness techniques, large population performance, and comparisons to other speaker modeling techniques (uni-modal Gaussian, VQ codebook, tied Gaussian mixture, and radial basis functions). The Gaussian mixture speaker model attains 96.8% identification accuracy using 5 second clean speech utterances and 80.8% accuracy using 15 second telephone speech utterances with a 49 speaker population and is shown to outperform the other speaker modeling techniques on an identical 16 speaker telephone speech task.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Chromatographic analyses of the free amino‐acids, organic acids and sugars in wheat plant extracts (1960)

Abstract Plants of three hard red winter wheat varieties differing in their resistance to attack by hessian fly ( Mayetiola destructor Say) were compared at the fourth leaf stage for their content of constituents extractable by 80% ethanol. Eleven amino‐acids, five organic acids and two inorganic acids were identified. Seven sugars were separated, two of which were unidentified polysaccharides. The main difference was that the susceptible variety (Tenmarq) contained allulose, or allulose in combination with some other component. This compound was present to a lesser extent in the semi‐resistant variety (Ponca) and not present in the plants of the resistant variety (C.I. 12855). Sorbitol also was found in Tenmarq but not in the other varieties.

Development of the Foil Bearing Technology (2009)

Development of the bearing technology with deformable elements of the bearing sleeve utilization are presented in the paper. Foil or a set of foils with the viscoelastic properties comprise the deformable element. Foil bearing technology is utilized mostly in the high-speed turbo machines, such as the energetic microturbines. This results the bearing operating regime: high rotational speed, high temperature, work in the friction conditions during machine start-up and rundown. Three foil bearing generations, which differ in the structure and properties with regard to load capacity, stiffness and undesirable variation damping, were distinguished in such bearing development. Technical solutions of the foil journal and thrust bearings were shown.
Automated Analysis and Prediction of Job Interview Performance (2016)

We present a computational framework for automatically quantifying verbal and nonverbal behaviors in the context of job interviews. The proposed framework is trained by analyzing the videos of 138 interview sessions with 69 internship-seeking undergraduates at the Massachusetts Institute of Technology (MIT). Our automated analysis includes facial expressions (e.g., smiles, head gestures, facial tracking points), language (e.g., word counts, topic modeling), and prosodic information (e.g., pitch, intonation, and pauses) of the interviewees. The ground truth labels are derived by taking a weighted average over the ratings of nine independent judges. Our framework can automatically predict the ratings for interview traits such as excitement, friendliness, and engagement with correlation coefficients of 0.70 or higher, and can quantify the relative importance of prosody, language, and facial expressions. By analyzing the relative feature weights learned by the regression models, our framework recommends to speak more fluently, use fewer filler words, speak as “we” (versus “I”), use more unique words, and smile more. We also find that the students who were rated highly while answering the first interview question were also rated highly overall (i.e., first impression matters). Finally, our MIT Interview dataset is available to other researchers to further validate and expand our findings.
CmapTools: A Knowledge Modeling and Sharing Environment (2004)

www.ihmc.us Abstract. Concept maps are an effective way of representing a person’s understanding of a domain of knowledge. Technology can further help by making it easy to construct and modify that representation, to manage large representations for complex domains, and to allow groups of people to share in the construction of the concept maps. CmapTools is a software environment developed at the Institute for Human and Machine Cognition (IHMC) that empowers users, individually or collaboratively, to represent their knowledge using concept maps, to share them with peers and colleagues, and to publish them. It is available for free for educational and not-for-profit organizations, and public servers have been established to promote the sharing of knowledge. The client-server architecture of CmapTools allows easy publishing of the knowledge models in concept map servers (CmapServers), and enables concept maps to be linked to related concept maps and to other types of media (e.g., images, videos, web pages, etc.) in other servers. The collaboration features enable remote users to asynchronously and/or synchronously collaborate in the construction of concept maps, and promote comments, criticism, and peer review. Public CmapServers have resulted in a large collection of knowledge models publicly available, constructed by users of all ages in a variety of domains of knowledge and from a large number of countries. 1
Additional support for an association between <i>OLR1</i> and milk fat traits in cattle (2007)

The bovine oxidized LDL receptor 1 (OLR1) was chosen as a candidate gene for association tests with milk composition traits. Genotyping of 773 Italian Brown Swiss for a SNP at position 8232 in OLR1 (NW_215807:g.8232C>A) revealed a frequency of 0.95 for the g.8232C allele. The University of Wisconsin Holstein resource population was genotyped for the OLR1 NW_215807:g.[7160C>T; 7161A>G; 8232C>A] SNPs, and four haplotypes were inferred based on the genotypes of sires and their daughters. Oxidized LDL receptor 1 haplotypes were significantly associated with fat percentage (P = 0.0015). Haplotype [C; A; C] was associated with a significant increase in fat percentage when compared with the other haplotypes.
Automatic Color Recognition System for Stockigt Sizing Test (II) - Application of the automatic recognition principle of red coloration for developing the novel automatic system - (2005)

Stockigt sizing test, which is readily affected by individual tester's bias as well as testing conditions in recognizing red coloration, had to be modified to improve its reliability and reproducibility. The novel testing system with the automatic recognizing program of red coloration was developed with the auxiliary equipments including an automatic liquid dispenser and a specimen shifter. The analysis program used a hue value of a droplet image in recognizing a point of time on red coloration instead of RGB values that are not similar to human perception of color. Hue was more sensitive in recognizing the red coloration of a droplet than the other two factors, Saturation and Value. During the test, the program records the time consumed up to a specific hue value of a droplet on a specimen. Differently from the conventional test, the automatic test could obtain a reliable and reproducible sizing degree with a minor error. Furthermore, the Stockigt sizing degree measured by the automatic system showed great correlations with contact angle and Hercules sizing degree. It means that such great correlations will contribute to the development of an integrated measuring system capable of predicting contact angle, surface tension, surface energy and Hercules sizing degree of paper and paperboards through the Stbckigt sizing test. It was meaningful to note that the automatic system for Stbckigt sizing test might be able to used to predict contact angle, Hercules and Cobb sizing degree, based upon the high correlation coefficients.
Transmission-line directional couplers for very broad-band operation (1965)

The development of coupled-transmission-line theory and applications has extended the bandwidth of certain microwave components to one decade or more. A review of the theory is presented in the most simple general form, which enables the effects of tolerances and perturbations to be calculated. A survey of available coupled-line configurations is presented, including a new printed re-entrant type, with, in some instances, more accurate formulas than those available in the literature. The theoretical aspects of this work are substantially complete, but there are practical difficulties associated with obtaining good directivity and higher-frequency devices.
Efficient and Non-genotoxic RNA-Based Engineering of Human T Cells Using Tumor-Specific T Cell Receptors With Minimal TCR Mispairing (2018)

Genetic engineering of T cells with tumor specific T-cell receptors (TCR) is a promising strategy to redirect their specificity against cancer cells in adoptive T cell therapy protocols. Most studies are exploiting integrating retro- or lentiviral vectors to permanently introduce the therapeutic TCR, which can pose serious safety issues when treatment-related toxicities would occur. Therefore, we developed a versatile, non-genotoxic transfection method for human unstimulated CD8<sup>+</sup> T cells. We describe an optimized double sequential electroporation platform whereby Dicer-substrate small interfering RNAs (DsiRNA) are first introduced to suppress endogenous TCR α and β expression, followed by electroporation with DsiRNA-resistant tumor-specific <i>TCR</i> mRNA. We demonstrate that double sequential electroporation of human primary unstimulated T cells with DsiRNA and <i>TCR</i> mRNA leads to unprecedented levels of transgene TCR expression due to a strongly reduced degree of TCR mispairing. Importantly, superior transgenic TCR expression boosts epitope-specific CD8<sup>+</sup> T cell activation and killing activity. Altogether, DsiRNA and <i>TCR</i> mRNA double sequential electroporation is a rapid, non-integrating and highly efficient approach with an enhanced biosafety profile to engineer T cells with antigen-specific TCRs for use in early phase clinical trials.
