Improved miniature wavelength meter based on polarisation state measurements (2007)

We propose an alternative design to the wavemeters based on scanning Michelson interferometers. Using realistic experimental parameters, we show that a relative accuracy of one part in 6x10<sup>-8</sup> can be reached with a displacement of the target mirror of only 360 &mgr;m. This improvment becomes possible thanks to the significant advances in polarimetry that permit measurement of the ellipsometric parameters &psgr; and &Dgr; with an accuracy of 0.07° with readily-available commercial equipment. This leads to an interpolation rate of &lgr;/10000. The proposed method has been setup and the chief parameters limiting its accuracy are determined.
CORROSION OF 0.2% CARBON STEEL AND ALUMINIZED 0.2% CARBON STEEL BENEATH KCl DEPOSIT (2005)

The corrosion behaviors of 0.2% carbon steel and aluminized 0.2% carbon steel were examined beneath KCl salt deposit in air at 750℃ and 800℃. The results showed that accelerated corrosion took place in 0.2% carbon steel and its corrosion products were rather thick, porous and poor adherent to the matrix. But the corrosion mass gain of aluminized 0.2% carbon steel was small. Although outer compact Al_2O_3 scale on the surface of specimens protected matrix and decreased corrosion rate, severe inner corrosion regions were formed between outer Al_2O_3 scale and matrix. The corrosion mechanism was discussed with respect to the thermodynamic aspects.
Anticlastogenic effects of <i>Hibiscus sabdariffa</i> fruits against sodium arsenite‐induced micronuclei formation in erythrocytes in mouse bone marrow (2004)

An in vivo micronucleus assay using albino mice was used to examine the anticlastogenic effects of a crude aqueous extract of Hibiscus sabdariffa fruits in bone marrow cells of mice. Various doses of freshly prepared crude extract of Hibiscus sabdariffa (50, 100 and 150 mg/kg b.w.) were given by gavaging to male laboratory bred Swiss albino mice for 7 days as a dietary supplement followed by a single dose of sodium arsenite (2.5 mg/kg b.w.) After 24 h, the animals were killed and bone marrow smears were prepared and stained in Giemsa. The results show that sodium arsenite effectively induced micronuclei in polychromatic erythrocytes (PCEs). Administration of a crude extract of Hibiscus sabdariffa led to a significant reduction of micronuclei in PCEs. The results also show that a combination of Hibiscus sabdariffa and sodium arsenite reduced significantly the frequencies of micronucleated PCEs induced by sodium arsenite.
Tn <i>125</i> -Related Acquisition of <i>bla</i> <sub>NDM</sub> -Like Genes in Acinetobacter baumannii (2011)

A multidrug-resistant Acinetobacter baumannii isolate recovered from a patient hospitalized in Switzerland after a transfer from Serbia produced the NDM-1 carbapenemase. The bla(NDM-1) gene was part of a chromosomally located Tn125 composite transposon bracketed by two copies of the same insertion sequence, ISAba125. This transposon was also associated with the acquisition and expression of the bla(NDM-2) gene in an A. baumannii isolate in Germany. Tn125 appears to be the main vehicle for dissemination of bla(NDM) genes in that species.
Effet des pratiques agroécologiques sur l'évolution des communautés d'arthropodes en vergers de manguiers à La Réunion (2015)

Les pratiques agroécologiques mises en place dans les vergers de manguiers du réseau Biophyto ont pour objectif d'augmenter la biodiversité fonctionnelle. Afin de vérifier cette influence, nous avons effectué un échantillonnage des arthropodes en période de floraison des manguiers (2012 et 2013). L'échantillonnage et la détermination de ces arthropodes présents dans chaque parcelle, nous ont permis d'estimer la richesse spécifique et l'abondance de deux niveaux trophiques : i) les herbivores et détritivores, ii) les prédateurs et parasitoïdes. En 2012, les différences entre les deux types de parcelles sont faibles, l'ensemble des pratiques agroécologiques ayant été mises en place ultérieurement. En 2013, La gestion d'un enherbement abondant et diversifie, conjointement à l'arrêt des traitements insecticides favorisent donc l'existence de communautés d'arthropodes abondantes et diversifiées pour les deux niveaux trophiques.
Effects of GnRH administration in the prepubertal heifer and post-partum cow (1987)

Postpartum cows received 1, 2.5 or 5 µg GnRH intravenously every 2 h for 48 h, as pulsed injections or continuous infusion. Of 6 cows, 4 ovulated after pulsed GnRH infusion; 0, 5 and 3 of 5 cows ovulated after continuous infusion of 1.0, 2.5 and 5.0 µg GnRH resp. Preovulatory LH surges occurred in 17 of 33 cows, and 20 cows showed luteal activity. These cows had higher oestradiol-17? and lower FSH concentrations during the pretreatment period than cows not showing a preovulatory LH surge. 23 four-month old beef heifers received 0.25, 0.5 or 2.5 µg GnRH per h for up to 120 h by continuous intravenous infusion. A further 12 received 5.0 µg GnRH per h for 120 h by subcutaneous infusion with or without progesterone pretreatment. Only 9 of 35 heifers showed luteal function, and the pituitary response was related to oestradiol concentration. A pulsatile pattern of LH release continued during and after constant GnRH infusion. It is concluded that the pituitary/ovarian response to GnRH treatment is governed by follicular state before treatment.
Application of feed-forward and feedback control to a photolithography sequence (2003)

Describe the implementation of supervisory control of three photolithography machines: a spincoat and bake track, a stepper and a developer. The objective of the experiment was to improve the reproducibility of critical dimensions of photoresist patterns. The results showed that the supervisory controller is capable of bringing the lithography process back to its previous specifications, even after all three machines have been taken down for maintenance and repairs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characteristics of Discharge Coefficient in a Rotating Disk System (1999)

The discharge coefficient of a long orifice in a rotating system is measured to examine the rotational effect on discharge behavior. The rotating system is comprised of a rotating disk and two stators on both sides of the rotating disk. Test rig is constructed to simulate the real turbine operating conditions. Pressure ratios between upstream and downstream cavities of the orifice range from 1.05 to 1.8, and rotational speed of the rotor disk is varied up to 10,000 rpm. The orifice hole bored through the rotor disk has length-to-diameter ratio of 10. For a better interpretation of discharge behavior, three-dimensional velocity field in the downstream and upstream cavities of the rotor is measured using a Laser Doppler Velocimetry. A new definition of the rotational discharge coefficient is introduced to consider the momentum transfer from the rotor to the orifice flow. Additional loss in the discharge coefficient due to pressure loss in the orifice hole at the inlet and exit regions is quantitatively presented in terms of the Rotation number and the compressibility factor. The effect of corner radiusing at the orifice inlet is also investigated at various rotational conditions.
Modified predictor–corrector numerical scheme for real‐time pseudo dynamic tests using state‐space formulation (2004)

Abstract This paper deals with an explicit numerical integration method for real‐time pseudo dynamic tests. The proposed method, termed the MPC‐SSP method, is suited to use in real‐time pseudo dynamic tests as no iteration steps are involved in each step of computation. A procedure for implementing the proposed method in real‐time pseudo dynamic tests is described in the paper. A state‐space approach is employed in this study to formulate the equations of motion of the system, which is advantageous in real‐time pseudo dynamic testing of structures with active control devices since most structural control problems are formulated in state space. A stability and accuracy analysis of the proposed method was performed based on linear elastic systems. Owing to an extrapolation scheme employed to predict the system's future response, the MPC‐SSP method is conditionally stable. To demonstrate the effectiveness of the MPC‐SSP method, a series of numerical simulations were performed and the performance of the MPC‐SSP method was compared with other pseudo dynamic testing methods including Explicit Newmark, Central Difference, Operator Splitting, and OS‐SSP methods based on both linear and non‐linear single‐degree‐of‐freedom systems.

A shift-register-based QCA memory architecture (2007)

A quantum-dot cellular automata (QCA) design of an nxm-bit, serial-access, shift-register based memory architecture is presented. The shift-register-based QCA memory architecture maintains data at a stable conformation, which is contrary to traditional data in-motion concept for QCA architectures. The memory architecture is based on an existing dual-phase-synchronized, line-based, one-bit QCA memory cell building block that provides size, density and latency improvements over other known one-bit memory cells through its novel clocking scheme. Read/write latencies up to 2X lower than the existing tile-based architecture with three-phase, line-based memory cells are obtained. Simulations with QCADesigner and HDLQ are performed on a sample 4times8 bit memory architecture implementation to verify functionality.
[Characterization of staphylococci in microtiter-plates (author's transl)]. (1977)

The conventional methods for the demonstration of coagulase, clumping-factor, fermentation of mannitol, protein A, alpha-, beta-, and delta-hemolysins and acid phosphatase were adapted to a microtitersystem (MTS). This led to a considerable saving in working-time and reagents. The biochemical reactions could be distinctly evaluated in the MTS (fig. 1). In all qualitative determinations there was complete agreement between the results obtained by MTS and the conventional procedures. In the quantitative endpoints there were only minor deviations (fig. 2,3,4). Thus, the MTS appeared to be a suitable procedure for the characterization of pathogenic staphylococci at a large scale.

Heap Charge Pump Optimisation by a Tapered Architecture (2005)

The heap charge pump represents an attractive voltage multiplier scheme in integrated circuits where only low-voltage devices are available. The paper presents a performance optimisation of the heap charge pump achieved by using a tapered architecture. The proposed optimisation allows improvements on the order of 30% in terms of maximum output voltage as compared to the conventional heap charge pump. A mathematical description of both the conventional and the proposed structure was developed. MATLAB/sup /spl reg//-based simulation results demonstrate the effectiveness of the proposed scheme.
Primary Peripheral Blood Eosinophils Rapidly Degrade Transfected Granulocyte-Macrophage Colony-Stimulating Factor mRNA (1999)

Despite increasing interest, very little information exists regarding gene regulatory mechanisms employed by eosinophils. This largely stems from the difficulty in transfecting these primary cells. In this study, we demonstrate that peripheral blood eosinophils (PBEos) can be successfully transfected with both GM-CSF cDNA and mRNA and reporter constructs by particle-mediated gene transfer. The transfection efficiency was 1.2% based on green fluorescent protein-positive cells. Promoter studies revealed CMV-driven expression vectors were initially active but rapidly quenched, while viral long terminal repeats had greater activity, indicating that certain viral constructs may be relatively poor to direct the production of transgenic proteins in PBEos. Exogenous GM-CSF mRNA was readily delivered and detected by Northern blot, permitting determination of its t1/2 in the absence of transcriptional poisons. These data show PBEos rapidly degraded GM-CSF mRNA with a t1/2 of 8 min. Mutant GM-CSF mRNAs, lacking the AUUUA motifs, were more stable, but were still rapidly degraded, suggesting the existence of accessory, destabilizing elements. We were able to measure minute amounts of intracellular GM-CSF after the transfection of mutant GM-CSF mRNA, but extracellular cytokine was below the sensitivity of our ELISA. However, the presence of secreted GM-CSF was established by in vitro, survival bioassay. In conclusion, the existence of this new technology should allow detailed studies of eosinophil-specific transcriptional and posttranscriptional regulation.

Low complexity, high-speed vlsi architectures for error correction decoders (2003)

This thesis is devoted to the low complexity, high speed VLSI architectures for various error correction decoders. 
To reduce the complexity of space-time block turbo coded system, a computationally efficient approach is proposed for the soft decoding of space-time block code, which can reduce the computation by up to 70 percent without any performance degradation. Additionally, for the considered outer code block turbo code, through reduction of test patterns scanned in the Chase algorithm and alternative extrinsic information computation, extra 0.3dB to 0.4dB coding gain is obtained with negligible hardware overhead. The overall complexity is approximately ten times less than that of the near-optimum decoder with coding gain loss of 0.5dB at the BER of 10−5 over AWGN channel. 
Based on the proposed interleaved single parity check turbo product codes, a parallel decoding structure is developed to increase the throughput. A new interleaver is constructed to further improve the coding gain. The extremely simple sign-min decoding is derived with only two additions needed to compute each bit's extrinsic information. Important implementation issues such as the finite precision analysis, sorting circuit design and interleaver memory are also presented. 
A systematic approach is proposed to develop high throughput decoder for quasi-cyclic low density parity check (LDPC) codes. Based on its properties, the two stages of belief propagation algorithm could be overlapped. To avoid the memory access conflict, the maximum concurrency of the two stages is explored by a novel scheduling algorithm. Consequently, the decoding throughput could be increased by about two times assuming dual-port memory is available. Furthermore, a load balanced approach is presented to reduce the area of logic core. A FPGA/ASIC implementation of irregular LDPC decoder is also presented. 
Long BCH codes achieve additional coding gain of 0.6dB compared to Reed-Solomon codes used for long-haul optical communication systems. A novel group matching scheme is proposed to further reduce the overall hardware complexity by 46% for BCH(2047, 1926, 23) code. The proposed scheme exploits the substructure sharing within a finite field multiplier (FFM) and among groups of FFMs.
Choline: Needed for Normal Development of Memory (2000)

Choline is a dietary component essential for normal function of all cells. It, or its metabolites, assures the structural integrity and signaling functions of cell membranes; it is the major source of methyl-groups in the diet (one of choline's metabolites, betaine, participates in the methylation of homocysteine to form methionine); and it directly affects nerve signaling, cell signaling and lipid transport/metabolism. In 1998, the National Academy of Sciences, USA, issued a report identifying choline as a required nutrient for humans and recommended daily intake amounts. Eggs are an excellent dietary source of choline. Pregnancy and lactation are periods when maternal reserves of choline are depleted. At the same time, the availability of choline for normal development of the brain is critical. When rat pups received choline supplements (in utero or during the second week of life), their brain function changed, resulting in the lifelong memory enhancement. This change in memory function appears to be due to changes in the development of the memory center (hippocampus) in the brain. The mother's dietary choline during a critical period in brain development of her infant influences the rate of birth and death of nerve cells in this center. These changes are so important that we can pick out the groups of animals whose mothers had extra choline even when these animals are elderly. Thus, memory function in the aged rat is, in part, determined by what the mother ate. This is not the first example of a critical nutrient that must be present at a specific time in brain development. If folate isn't available in the first few weeks of pregnancy, the brain does not form normally. Thus, we suggest that pregnancy is a period when special attention has to be paid to dietary intake.
Interactions between Psychological Stress and Drinking Status in Relation to Diet among Middle-Aged Men and Women: A Large-Scale Cross-Sectional Study in Japan (2015)

The aim of this study was to investigate the interaction between psychological stress (PS) and drinking status in relation to diet among middle-aged Japanese men and women in a large-scale cross-sectional study. The study population included 5,587 middle-aged Japanese men and 2,718 middle-aged Japanese women who underwent annual health checkups. The subjects were divided into 2 groups (non-drinkers and drinkers) and classified as having low, moderate, or high self-reported PS levels. Energy-adjusted food and nutrient consumption was assessed with a validated food frequency questionnaire. Using a general linear model, food and nutrient consumption was estimated for each self-reported PS level in the 2 groups (non-drinkers and drinkers) and the interactions between self-reported PS levels and drinking status were calculated. In men, pork and beef; squid, octopus, shrimp, and clams; eggs; mushrooms; Japanese-style sweets; ice cream; bread; Chinese noodles; coffee; and soda as foods and protein, animal protein, fat, animal fat, carbohydrate, monounsaturated fatty acid, polyunsaturated fatty acid (PUFA), n-3 PUFA, n-6 PUFA, cholesterol, vitamin D, vitamin B2, vitamin B6, vitamin B12, niacin, pantothenic acid, magnesium, phosphorus, and zinc as nutrients significantly interacted with self-reported PS levels and drinking status (p for interaction <0.05 for all). No specific interactions were found in women. These findings suggest interactions between PS levels and drinking status with consumption of some foods and nutrients, especially macronutrient intake, in men but not in women.
New anti‐GD2 monoclonal antibodies produced from gamma‐interferon‐treated neuroblastoma cells (1989)

Abstract Three monoclonal antibodies (IgG 2 ) have been produced from hybridomas obtained by fusion of murine myeloma cells and spleen cells of mice hyperimmunized with gamma‐interferon‐treated neuroblastoma cells. The 3 MAbs, 7A4, 2A6 and IG8, detected an antigen present on neuroblastoma tumors and cell lines, but also on some neuro‐ectoderm‐derived tissues and cells. All 3 clones were shown to react with an epitope of the di‐sialo‐ganglioside GD2 molecules highly expressed by some neuro‐ectoderm‐derived tumors, mainly neuroblastoma. Whereas MAb IG8 specificity was restricted to GD2 and its o‐acylated form, MAb 2A6 and 7A4 were also able to detect GD3 at high concentration of antibody as shown by TLC analysis and immunodetection. The 3 MAbs were able to lyse 100% neuroblastoma cells in the presence of rabbit or human complement. Direct binding assays with 125 ‐labelled MAbs showed that MAb 7A4 might be a good candidate for in vivo immunolocalization experiments. The high proportion of anti‐GD2 MAbs obtained by our fusion and the increased binding of anti‐GD2 MAbs on gamma‐IFN‐treated neuroblastoma cells suggests a modulation of the exposure and an increase in the immunogenicity of GD2 induced by gamma‐IFN.

Dynamic resonant frequency control of ultrasonic transducer for stabilizing resonant state in wide frequency band (2017)

Controlling the resonant frequency of ultrasonic transducers is important to achieve the excellent performance of ultrasonic devices. The resonant frequency can be shifted by a nonlinear effect or by increasing the temperature under high-power operation. We propose a resonant frequency control method during the transducer's operation that enables the dynamic compensation of resonant frequency shifts. To realize this, a transducer with passive piezoelectric parts was fabricated. By controlling the electric boundary condition of the passive piezoelectric parts between short and open by utilizing a metal–oxide–semiconductor field-effect transistor (MOSFET), the stiffness was changed, thus modifying the resonant frequency. In both simulation and experiment, the resonant frequency was modified successfully by controlling the switching duty ratio of the MOSFET. Additionally, a system for exciting a transducer at a resonant state with a wide frequency band was demonstrated.
STUDY OF MAXIMUM A POSTERIORI SPEAKER ADAPTATION FOR AUTOMATIC SPEECH RECOGNITION OF PATHOLOGICAL SPEECH (2006)

This paper shows the results achieved by the Maxi-mum A Posteriori (MAP) speaker adaptation method in a task of isolated word Automatic Speech Recognition (ASR) system for 6 young speakers with different types of speech pathologies. In this work, the influence of two im-portant variables in speech recognition and speaker adap-tation are studied. On one hand, the performance of the ASR system depending on the acustic unit used by the system (word level unit and context-dependent unit) is analized. On the other hand, how the size of the train-ing set influences the results when using MAP adaptation is studied. The results of this work with the first subset of the Alborada-GTC corpus show that context-dependent units are the most reliable acoustic unit to use, while the use of 2 utterances of the vocabulary recorded in the cor-pus is enough for getting the best results in speaker adap-tation. 1.
