[The epidemiological characteristics of group C rotavirus in Lulong area and the analysis of diversity of VP6 gene]. (2013)

The infection rate of GCRV was high from 2007 to 2008 in Lulong. Homology and phylogenetic analysis showed that VP6 gene diversity was widespread. The experimental data provided basis for molecular characteristics of porcine GCRVs.
An abrupt spin transition based on short S⋯S contacts in a novel Fe(ii) complex whose ligand contains a 1,3-dithiole ring (2003)

The first preparation of an Fe(II) spin-crossover complex including a 1,3-dithiole ligand is reported. Crystal analyses of both the low- and the high-temperature phases reveal that short S...S contacts play a key role in an abrupt spin transition.
La Syllabe comme unité de traitement en production verbale orale et écrite (2007)

Le present travail a pour objectif principal l'etude du role fonctionnel de la syllabe en production verbale orale et ecrite de mots isoles. Suite a une tentative de definition de « ce qu'est exactement une syllabe » dans une Introduction, nous avons rapporte des arguments en faveur d'un role fonctionnel de cette unite en perception visuelle et auditive. Le Chapitre I presente une revue de la litterature portant sur la production verbale orale et ecrite conceptuellement dirigee (Caramazza & Miceli, 1990 ; Dell, 1986 ; Levelt, Roelofs, & Meyer, 1999). Les differents niveaux de traitement (conceptuel, syntaxique, lexical et moteur) et les propositions concernant les mecanismes de traitement impliques a chacune de ces etapes sont presentes. Une attention particuliere a ete portee aux propositions des principaux modeles concernant le role de la syllabe dans les processus d'acces lexical et de planification motrice. Le Chapitre II est consacre a un effet qui est a l'origine d'un vif debat : l'effet d'amorcage syllabique. Ferrand, Segui et Grainger (1996) ont montre que la presentation d'un groupe de segments correspondant a la premiere syllabe d'un mot (e.g., ba-baleine ; balbalcon) facilite plus la denomination qu'un groupe de segments plus court (e.g., ba-balcon) ou plus long (bal-baleine). Nous avons essaye de repliquer ce resultat en denomination orale d'images (Experiences 2a, 2b et 3). Nous avons rapporte des donnees en faveur de l'hypothese du recouvrement segmental (Sciller, 1998, 1999, 2000). Nous avons ensuite teste si le temps de presentation de l'amorce (Experience 4) et le moment de presentation du groupe de segments (Experience 5) pouvaient expliquer l'absence d'effet d'amorcage syllabique. La encore, les donnees sont en accord avec l'hypothese du recouvrement segmental (Schiller, 1998, 1999, 2000). Nous avons aussi explore la possibilite d'obtenir cet effet en production verbale ecrite (Experiences 1a et 1b). Dans le Chapitre III, nous avons teste l'hypothese selon laquelle les latences d'initialisation de mots monosyllabiques devraient etre plus courts que celles de mots bisyllabiques, si la syllabe joue un role fonctionnel en production verbale orale et ecrite. Des etudes pour les deux modalites ont repondu par la negative (Bachoud-Levi et al., 1998 ; Lambert, 1999 ; Lambert et al., sous presse ; Roelofs, 2002b). Toutefois, Meyer, Roelofs et Levelt, (2003) ont propose qu'un critere temporel de reponse (Lupker et al., 1997) influence l'instant d'initialisation de la reponse. En consequence, un effet du nombre de syllabes peut apparaitre. Nous avons essaye de repliquer ce resultat en production verbale orale (Experience 6) et de l'etendre a la production verbale ecrite (Experience 7). Toutefois, nous n'avons pas rapporte de donnees en faveur de l'hypothese de Meyer et collaborateurs (2003) pour les deux modalites. Le Chapitre IV a pour objectif de faire une synthese des resultats que nous avons obtenus et de proposer des perspectives de recherches.

Design and engineering of the Alcator C-Mod lower hybrid current drive system (2003)

The PSFC group of MIT and PPPL are jointly developing a Lower Hybrid Current Drive (LHCD) system for installation on the Alcator C-Mod tokamak, with the primary goal of driving plasma current. Twelve Klystrons will feed a coupler with an input power of 3 MW at 4.6 GHz and a pulse length of 5 seconds. The coupler is composed of 4 arrays, each with 24 wave-guides (96 total) which are stacked poloidally and are symmetric about both the vertical and horizontal planes. The four-stacked arrays are installed through a single equatorial port and can be axially adjusted to provide optimum plasma coupling. Material selections and spatial limitations required innovative design solutions that will be described.
Thermochemical Processing of Animal Fat and Meat and Bone Meal to Hydrocarbon Based Fuels (2015)

The results of the study at hand may have implications for treatment of grease, lipid fractions, free fatty acids (FFA) and salts of FFA extracted from wastes of food industry, bio-refineries or sewage sludge as well as contaminated lipid containing forage. The goal of the study is, to prevent such contaminated wastes from entering the food chain. The following ways of treatment are proposed. Thermal conversion of waste fats from rendering plants or lipids in the presence of aluminosilicates of the zeolite family produce hydrocarbons with net calorific values in the range of 40–42 MJ/kg. NMR studies show aliphatic hydrocarbons as main product at T = 400°C. The spectrum of products is shifted to alkyl benzenes at T = 550°C. In case of sodium carbonate conversion is achieved in the presence of 5% water at T = 430 ± 20°C yielding mainly a liquid bio-crude with a low acid index, a mixture of non-condensable gases and minor amounts of coke. Rectification of bio-crude from animal fat produces 65.8% of hydrocarbon based bio-diesel and 13.3% of gasoline type hydrocarbons. Distillation curve for bio-diesel is in accordance with DIN EN 490. However, the gasoline fraction lacks low boiling hydrocarbons indicating the necessity for technical improvements of condensers. Sodium carbonate is found to be effective as well as being relatively inexpensive compared to zeolite catalysts. Finally, successful conversion of meat and bone meal to biochar is proved by solid-state 13C-NMR.
THE OPTIMAL BUDGET (1979)

This paper investigates the mix of public expenditures that maximizes the benefits derived from a given total budget. Using a model which permits the measuring of benefits from referendum-voting behavior, optimal budgets are found for different levels of individual income and education in Switzerland, and their changing composition is traced. The paper also derives the optimal budget for the jurisdiction as a whole, and compares the results with the actually existing budget. The findings show that about one half of the budget is optimally allocated, while the other one half appears to represent a social compromise rather than the imposition of the preferences of a particular income group.
Postnatal epigenetic regulation of intestinal stem cells requires DNA methylation and is guided by the microbiome (2015)

Our results demonstrate that the suckling period is critical for epigenetic development of intestinal stem cells, with potential important implications for lifelong gut health, and that the gut microbiome guides and/or facilitates these postnatal epigenetic processes.
Non-invasive versus ex vivo measurement of mitochondrial function in an endotoxemia model in rat: Toward monitoring of mitochondrial therapy (2019)

Mitochondrial function has been predominantly measured ex vivo. Due to isolation and preservation procedures ex vivo measurements might misrepresent in vivo mitochondrial conditions. Direct measurement of in vivo mitochondrial oxygen tension (mitoPO<sub>2</sub>) and oxygen disappearance rate (ODR) with the protoporphyrin IX-triplet state lifetime technique (PpIX-TSLT) might increase our understanding of mitochondrial dysfunction in the pathophysiology of acute disease. LPS administration decreased mitochondrial respiration (ODR) in vivo but did not alter mitochondrial function as assessed with ex vivo techniques (high resolution respirometry and specific complex determinations). PpIX-TSLT measures in vivo mitoPO<sub>2</sub> and ODR and can be applied non-invasively at the skin.
Fluoro-pegylated (FPEG) Imaging Agents Targeting Aβ Aggregates (2006)

A novel approach of producing positron emission tomography (PET) imaging agents through the formation of bioconjugates based on a pegylation-fluorination strategy resulting in fluoro-pegylated (FPEG) molecules is reported. This approach offers a simple and easy method by which to incorporate 18F in the target molecule without an appreciable increase in the lipophilicity. After 18F labeling, this convenient approach leads to PET imaging probes binding to Abeta aggregates in the brain (an important factor associated with Alzheimer's disease) using the known core structures, such as [2-(4-dimethylaminophenyl)-vinyl]-benzoxazol (3') or 2-phenylbenzothiazole (4). This approach appears to be effective in some core structures, but it cannot be uniformly applied to all structures.

A Programmable Debugging Aid For (1986)

The authors consider the problem of providing hardware support for the development of real-time software in the context of a specific computer architecture, the Selenia MARA family of multi-microprocessor systems, under the constraint that no modifications to existing MARA hardware be involved. The specification of a programmable debugging aid (PDA), that can support program performance evaluation as well as program debugging and testing is described. The PDA hardware has been fully designed, and is being implemented as a research prototype.
A 90-nm Wideband Merged CMOS LNA and Mixer Exploiting Noise Cancellation (2007)

This paper describes the design and implementation of a wideband merged LNA and mixer chip covering the frequency range from 0.1 to 3.85 GHz using 90-nm CMOS technology. Its high level of integration as well as its low power consumption makes it suitable for the rapidly growing software defined radio RF receivers. The chip performance achieves S11 below -10 dB along the entire band and a minimum single side band noise figure of 8.4 dB at IF frequency of 70 MHz. Power conversion gain is measured to be 12.1 dB while the input referred 1 dB compression point is measured to be -12.8 dBm. The chip core consumes only 9.8 mW from a 1.2 V supply with a die area, including the pads, of 0.88 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>
Raman-assisted parametric generation of non phase-matched waves in normally dispersive optical ﬁbers (1999)

An ordinary three-wave mixing (TWM) process in standard or birefringent single-mode fibers commonly refers to the interaction of a central-frequency wave at frequency ω0 with a pair of upshifted (anti-Stokes) and downshifted (Stokes) sidebands at frequencies ω2 = ω0+Ω and ω1=ω0−Ω, respectively [1, 2].
Genetic Variations of Complete Coding Sequence of Bovine Growth Hormone Gene (2009)

Typical bovine species or subspecies of Bos taurus,Bos indicus,Bos grunniens,Bos frontalis,Bubalus bubalis(Swamp buffalo)and Bubalus bubalis(River buffalo)were used as experimental populations to detect genetic variations of complete coding sequence of bGH gene.The results showed that the GH gene was 654 bp in length of all 6 populations and 16 SNP sites were determined from coding region.There was no variation site in the 1 th exon and 3,5,1 and 7 variation sites in the 2 th exon,3 th exon,4 th exon and 5 th exon,respectively.It was indicated that the 5 th exon was the very high mutation in encoding region.Great difference of the distribution of SNP sites arised between different bovine species or subspecies.Of the total 16 substitutions,13 sites were synonymous and only 3 sites were nonsynonymous.Three nonsynonymous sites were located in the 2 th exon,4 th exon and 5 th exon,and caused relevant amino acid revised.

Atomic layer deposited α -Ga 2 O 3 solar-blind photodetectors (2019)

Abstract Low temperature atomic layer deposition was used to deposit α -Ga 2 O 3 films, which were subsequently annealed at various temperatures and atmospheres. The α -Ga 2 O 3 phase is stable up to 400 °C, which is also the temperature that yields the most intense and sharpest reflection by x-ray diffraction. Upon annealing at 450 °C and above, the material gradually turns into the more thermodynamically stable ε or β phase. The suitability of the materials for solar-blind photodetector applications has been demonstrated with the best responsivity achieved being 1.2 A W −1 under 240 nm illumination and 10 V bias, for the sample annealed at 400 °C in argon. It is worth noting however that the device performance strongly depends on the annealing conditions, with the device annealed in forming gas behaving poorly. Given that the tested devices have similar microstructure, the discrepancies in device performance are attributed to hydrogen impurities.
TH‐C‐L100E‐01: PET CT Workshop — Accreditation and Quality Assurance (2007)

The objectives of this workshop are to provide an overview of the different commercially available PET/CT scanners and to gain the necessary knowledge of PET/CT QC/QA procedures as well as the criteria needed for PET scanner accreditation and acceptance testing. The first objective will be met during the first day whereby three presentations will be provided covering the PET/CT scanner offerings from GE Health Care, Siemens Medical Solutions, and Philips Medical Systems respectively. The presentations will focus on PET scanner design, performance, and capabilities and will be given by respective users of the equipment rather than representatives of the manufacturers. The second objective will be met during the second day of the workshop, whereby four speakers will discuss topics on PET/CT QC/QA procedures, PET NEMA acceptance testing, PET ACR accreditation, and PET site shielding calculations and requirements.
The π-rotation low-density parity check codes (2002)

We introduce an ensemble of quasi-regular low-density parity check error control codes we call /spl pi/-rotation LDPC codes. These codes are completely defined by a single permutation vector of length n/8 where n is the length of the code. We present an efficient encoding scheme and circuit design based on the single permutation. Simulation results indicate that these codes perform as well as regular low density parity check codes based on completely random matrix constructions. These features make the /spl pi/-rotation code valuable for practical communication system implementation.
Channel Allocation in 802.11-Based Mesh Networks (2006)

Abstract — IEEE 802.11 (WiFi) has been used beyond its original intended purpose of a tether-free LAN. In this paper, we are interested in the use of 802.11 in mesh networks. Specifically, we consider those which involve directional antennas and longdistance point-to-point links. In recent work, the 2P MAC protocol has been designed to suit such a network architecture. In this paper, we assume the use of the 2P MAC protocol in the links of the network, and consider the problem of link channel allocation. We first formulate the problem of minimizing the mismatch between link capacities desired by the network operator and that achieved under a channel allocation. We show that this problem is NP-hard. We then explore several heuristics for channel allocation and find a set of heuristics that achieve the optimal allocation in most scenarios. I.
Characteristics of Tungsten Carbide Films Prepared by Plasma-Assisted ALD Using Bis(tert-butylimido)bis(dimethylamido)tungsten (2003)

Tungsten carbide thin films were prepared by plasma-assisted atomic layer deposition (ALD) using bis(tert-butylimido)bis(dimethylamido)tungsten at 250°C. The effects of plasma pulse time, radio frequency power, and the ratio on the film properties, such as resistivity, surface roughness, step coverage, and stability in air, were examined. The film growth rate (thickness/cycle) was in the range 0.04-0.07 nm/cycle and the resistivity of the films varied from 295 to 22,000 μΩ cm, depending on the plasma conditions. The films were smooth and the conformality of the films deposited in 0.15 μm holes with an aspect ratio of 15:1 was 100%. © 2003 The Electrochemical Society. All rights reserved.
A process and device model for GaAs MESFET technology: GATES (1989)

A combined process and device modeling program for GaAs MESFET digital and microwave integrated-circuit technology is described. GATES (for GaAs transistor engineering models) is designed to meet the needs of process, test, and manufacturing engineers who require answers to questions about how process parameters and tolerances affect device performance and uniformity, but who have limited access to large-computer modeling tools. The program makes extensive use of analytical models. The physical models used for ion implantation, dopant diffusion and other process factors and the methods used to calculate carrier profiles, threshold voltages, layer resistivities. MESFET parasitic resistances, and I-V characteristics are discussed. The I-V curves can be fitted to expressions suitable for use in circuit optimization codes such as SPICE. It is shown how to calibrate some of the physical quantities.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Intracellular Ca 2+ signaling and store-operated Ca 2+ entry are required in Drosophila neurons for flight (2009)

Neuronal Ca(2+) signals can affect excitability and neural circuit formation. Ca(2+) signals are modified by Ca(2+) flux from intracellular stores as well as the extracellular milieu. However, the contribution of intracellular Ca(2+) stores and their release to neuronal processes is poorly understood. Here, we show by neuron-specific siRNA depletion that activity of the recently identified store-operated channel encoded by dOrai and the endoplasmic reticulum Ca(2+) store sensor encoded by dSTIM are necessary for normal flight and associated patterns of rhythmic firing of the flight motoneurons of Drosophila melanogaster. Also, dOrai overexpression in flightless mutants for the Drosophila inositol 1,4,5-trisphosphate receptor (InsP(3)R) can partially compensate for their loss of flight. Ca(2+) measurements show that Orai gain-of-function contributes to the quanta of Ca(2+)-release through mutant InsP(3)Rs and elevates store-operated Ca(2+) entry in Drosophila neurons. Our data show that replenishment of intracellular store Ca(2+) in neurons is required for Drosophila flight.
Approximate Moments for the Serial Correlation Coefficient (1957)

The first order Gaussian auto-regressive process $(x_t)$ may be defined by the stochastic difference equation \begin{equation*}\tag{1}x_t = \rho x_{t-1} + u_t,\end{equation*} where the $u$'s are NID(0, 1) and $\rho$ is an unknown parameter. The choice of a statistic as an estimator for $\rho$ depends on the initial conditions imposed on the difference equation (1). The so-called "circular" model is obtained by considering a sample of size $N$ and then assuming that $x_{N + 1} = x_1$. An appropriate estimator for $\rho$ in this case is the circular serial correlation coefficient \begin{equation*}\tag{2} r = \frac{\sum^N_{t = 1} x_tx_{t + 1}}{\sum^N_{t = 1} x^2_t}\quad (x_{N + 1} = x_1).\end{equation*} Leipnik [1] has derived an approximate density function \begin{equation*}\tag{3} f(t) = \frac{\Gamma\big(\frac{N + 2}{2}\big)}{\Gamma\big(\frac{N + 1}{2} \Gamma\big(\frac{1}{2}\big)} (1 - 2t\rho + \rho^2)^{-N/2}(1 - t^2)^{(N - 1)/2}\end{equation*} for the estimator $r$. Leipnik also evaluated the first two moments of this distribution. In this paper a formula is obtained which gives $E(r^k)$ as a polynomial of degree $k$ in $\rho$.
Cognitive Radio Networks With Probabilistic Relaying: Stable Throughput and Delay Tradeoffs (2015)

This paper studies fundamental throughput and delay tradeoffs in cognitive radio systems with cooperative secondary users. We focus on randomized cooperative policies, whereby the secondary user (SU) serves either its own queue or the primary users (PU) relayed packets queue with certain service probability. The proposed policy opens room for trading the PU delay for enhanced SU delay, and vice versa, depending on the application QoS requirements. Towards this objective, the system's stable throughput region is characterized. Furthermore, the moment generating function approach is employed and generalized for our system to derive closed-form expressions for the average packet delay for both users. The accuracy of these expressions is validated through simulations. Analytical and simulation results reveal that the service probability can steer the system into prioritizing PU's traffic at the expense of SU's QoS, or vice versa, independently from the admission probability. Alternatively, the ability of the admission probability to control the throughput and delay at the PU or the SU depends on the selected value for the service probability as well as the channel conditions. Finally, it is shown how the service and admission probabilities could be used to achieve the desired QoS level to both PU and SU.
A frequency scalable coding scheme employing pyramid and subband techniques (1994)

A flexible layered coding scheme using block-based DCT domain decimation has been simulated in software. A conditional replacement scheme which switches adaptively between the pyramid and subband approaches at the coefficient level was studied. Experimental results comparing the adaptive scheme against the pyramid approach show that this new approach increases the overall coding efficiency of the scalable coder by up to 1 dB.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
