Power Factor Improvement of a Linear Vernier Permanent-Magnet Machine Using Auxiliary DC Field Excitation

Vernier permanent-magnet (VPM) machines attract more and more attention recently because of the high-torque density and low-speed operation features. Due to the vernier structure for field modulation, its power factor (PF) usually is lower than that of the conventional PM machines. In this paper, a new linear VPM machine for improving the PF is proposed. By using an auxiliary dc field winding to provide an additional excitation, the air-gap flux excited by PMs is compensated. The proposed machine has a similar structure to the split-pole VPM machines with surface-mounted PMs. For implementing the auxiliary dc field winding, a parallel-hybrid excitation topology and consequent-pole PM machine structure are adopted. The machine topology, modeling, and operating principle are discussed. Both simulation and experimentation show that the PF of the machine can be improved by the auxiliary dc field excitation.
High-resolution CT findings of diffuse bronchioloalveolar carcinoma in 38 patients.

OBJECTIVE The purpose of this study was to analyze the high-resolution CT features of diffuse bronchioloalveolar carcinoma and determine the useful findings in differential diagnosis. MATERIALS AND METHODS High-resolution CT scans of 38 patients with pathologically proven diffuse bronchioloalveolar carcinoma were reviewed. Sequential CT scans were obtained in 15 patients. The high-resolution CT findings were compared with those of eosinophilic pneumonia (n = 22), multiple pulmonary metastases (n = 12), and tuberculosis (bronchogenic: n = 22; miliary: n = 12). RESULTS High-resolution CT findings of diffuse bronchioloalveolar carcinoma included ground-glass opacity (n = 29), consolidation (n = 29), nodules (n = 28), centrilobular nodules (n = 26), peripheral distribution (n = 19), and air bronchogram (n = 18). According to the major features, high-resolution CT findings of diffuse bronchioloalveolar carcinoma could be classified into three patterns: predominantly ground-glass (n = 4), consolidative (n = 22), and multinodular (n = 12). Most patients with diffuse bronchioloalveolar carcinoma had a mixture of these findings. The frequency of findings of diffuse bronchioloalveolar carcinoma on high-resolution CT was not different from that of tuberculosis, but the predominant distribution of the nodules and areas of ground-glass attenuation differed between the two. Difference in distribution between bronchioloalveolar carcinoma and bronchogenic tuberculosis included ground-glass opacity remote from the consolidation and a lower lung predominance. CONCLUSION Although these high-resolution CT findings are not specific, the combination of consolidation and nodules and the coexistence of centrilobular nodules and remote areas of ground-glass attenuation are characteristic of diffuse bronchioloalveolar carcinoma.
ARE THERE GENETIC DETERMINANTS FOR THE GLUCOSE INTOLERANCE OF ACROMEGALY?

A genetic marker identifying the two parental insulin genes has been studied in 51 Caucasian acromegalics by Southern blot hybridization techniques using a cloned insulin gene probe. Two main DNA insertion classes were detected corresponding to the class 1 and class 3 alleles and thus the following genotypes were found: 1/1, 1/3 and 3/3. The acromegalics were subdivided depending on whether they had a normal (n= 30) or abnormal (n= 21) response to a 50 gm oral glucose tolerance test before treatment. The phenotype frequencies in the former group were 1/1, 43%; 1/3, 53%; and 3/3, 4%; and in the latter group the corresponding figures were 76%, 24% and 0%. The relative incidence of concordance of the phenotype 1/1 with abnormal glucose tolerance in acromegaly was 4.2. This phenotype is also associated with insulin dependent (Type 1) diabetes mellitus.
Partial reset methodologies for improving random-pattern testability and BIST of sequential circuits

The use of partial reset has been shown to have significant impact on test generation in a stored-pattern test application environment for sequential circuits. In this paper, we explore the use of partial reset in fault-independent testing and its application to built-in self-test of nonscan sequential circuits. Switching activities of circuit nodes coupled with the node interconnection structure is used to select a subset of the circuit flip-flops to be reset to logic 0 or logic 1 during test application. An average improvement of 15% in fault-coverage is obtained for circuits resistant to random pattern testing over existing full reset methods. We also present a technique to insert observable test points based on activity propagation analysis. With the combined partial reset and observable test point insertion methodologies, high fault coverages were obtained for most of our benchmark circuits.
Behavioral Counseling After Screening for Alcohol Misuse in Primary Care: A Systematic Review and Meta-analysis for the U.S. Preventive Services Task Force

BACKGROUND Alcohol misuse, which includes the full spectrum from risky drinking to alcohol dependence, is a leading cause of preventable death in the United States. PURPOSE To evaluate the benefits and harms of behavioral counseling interventions for adolescents and adults who misuse alcohol. DATA SOURCES MEDLINE, EMBASE, the Cochrane Library, CINAHL, PsycINFO, International Pharmaceutical Abstracts, and reference lists of published literature (January 1985 through January 2012, limited to English-language articles). STUDY SELECTION Controlled trials at least 6 months' duration that enrolled persons with alcohol misuse identified by screening in primary care settings and evaluated behavioral counseling interventions. DATA EXTRACTION One reviewer extracted data and a second checked accuracy. Two independent reviewers assigned quality ratings and graded the strength of the evidence. DATA SYNTHESIS The 23 included trials generally excluded persons with alcohol dependence. The best evidence was for brief (10- to 15-minute) multicontact interventions. Among adults receiving behavioral interventions, consumption decreased by 3.6 drinks per week from baseline (weighted mean difference, 3.6 drinks/wk [95% CI, 2.4 to 4.8 drinks/wk]; 10 trials; 4332 participants), 12% fewer adults reported heavy drinking episodes (risk difference, 0.12 [CI, 0.07 to 0.16]; 7 trials; 2737 participants), and 11% more adults reported drinking less than the recommended limits (risk difference, 0.11 [CI, 0.08 to 0.13]; 9 trials; 5973 participants) over 12 months compared with control participants (moderate strength of evidence). Evidence was insufficient to draw conclusions about accidents, injuries, or alcohol-related liver problems. Trials enrolling young adults or college students showed reduced consumption and fewer heavy drinking episodes (moderate strength of evidence). Little or no evidence of harms was found. LIMITATIONS Results may be biased to the null because the behavior of control participants could have been affected by alcohol misuse assessments. In addition, evidence is probably inapplicable to persons with alcohol dependence and selective reporting may have occurred. CONCLUSION Behavioral counseling interventions improve behavioral outcomes for adults with risky drinking. PRIMARY FUNDING SOURCE Agency for Healthcare Research and Quality.
Identification and characterization of enteric adenoviruses in infants and children hospitalized for acute gastroenteritis

Enteric adenoviruses are important etiological agents associated with sporadic infections and outbreaks of acute gastroenteritis in infants and children. Fecal samples were collected from 439 hospitalized patients in the years 2005–2007 from Pune, Aurangabad, and Nagpur cities of western India to identify the most prevalent strains of enteric adenoviruses. The viruses were detected by PCR and characterized by sequencing and phylogenetic analysis. The prevalence of enteric adenoviruses in patients from Pune, Aurangabad and Nagpur was found to be 9% (10/111), 7% (7/100), and 7.5% (17/228), respectively. Sequence based analysis of the partial hexon and/or fiber genes showed the presence of adenovirus serotypes 40, 41, and 31 and variations at the subgenus and strain level. Phylogenetic analysis of the adenovirus strains indicated 98–100% homology with adenovirus 40 of the UK, 96–99% with adenovirus 41 of the USA and 94–100% with adenovirus 31 of Austria. The study indicates circulation of enteric adenovirus serotypes 40 and 41 with an unreported serotype 31 in sporadic cases of gastroenteritis. This is the first report from India on the association of enteric adenoviruses with acute gastroenteritis. J. Med. Virol. 81:60–64, 2009. © 2008 Wiley‐Liss, Inc.
Habitat Quality in Association with Herd Health in Two Bighorn Sheep (Ovis canadensis canadensis) Populations

Multiple factors have been identified as elements of the respiratory disease complex in Rocky Mountain bighorn sheep (Ovis canadensis canadensis). We hypothesized that differences in health factors and Pasteurellaceae in the upper respiratory tracts could exist between populations of bighorn sheep with and without histories of pneumonic epizootics. We evaluated bighorn sheep in the Big Creek area of Central Idaho which had a history of respiratory disease, and hunter-harvested bighorn sheep from the Montana Spanish Peaks Range which had no history of respiratory disease. Factors evaluated included Pasteurellaceae, indicators of exposure to respiratory viruses, lungworm (Protostongylus spp.) loads, nutritional status and forage nutrient availability. Pasteurellaceae were isolated from both populations; however, significant differences (P < 0.01) in β-hemolysis and cytotoxicity were detected between isolates from the two populations; 64% of isolates cultured from Idaho were β-hemolytic and 38% of those produced >50% cytotoxicity. In contrast, 19% of the isolates from Montana were βhemolytic and none of those produced cytotoxicity >50%. Low serum antibody titers against bovine viral diarrhea, and bovine respiratory syncytial virus were detected in Idaho bighorn sheep following a pneumonic epizootic and in both herds against parainfluenza-3 virus. Low lungworm loads were detected in both herds. Forage nutrient values were similar for the two populations; however, the selenium level present in the Montana forage was significantly higher (P = 0.06) than that detected in the Idaho forage. It is concluded that variances in Pasteurellaceae virulence factors and dietary selenium, important in immune function, may be critical factors to consider when identifying conditions favoring a pneumonic epizootic.
Novel Phosphatase Encoded by the cobC gene of Salmonella + + P P T 1 cob 0 cobC ORF ? I I I I 100 +

We report the identification of a new locus, designated cobC, involved in the assembly of the nucleotide loop of cobalamin in Salmonella typhimurium. The cobC gene has been mapped, cloned, and sequenced. DNA sequence analysis suggested that cobC is divergently transcribed from the adjacent cobD gene and suggests that the regulatory region of these genes overlap. The cobC gene codes for a predicted polypeptide of 26 kDa with striking homology to phosphoglycerate mutase, fructose-2,6-bisphosphatase, and acid phosphatase enzymes. In vitro experiments demonstrated that CobC dephosphorylated the cobalamin biosynthetic intermediate iV-(5-phospho-(~-~-ribosyl)-5,6-dimethylbenzimidazole to generate ~-a-~-ribosyl-5,6-dimethylbenzimidazole. In vivo data showed that the lack of cobC function blocks the synthesis of cobalamin from its precursors cobinamide and 5,6-dimethylbenzimidazole, i.e. it prevents the assembly of the nucleotide loop of cobalamin. Additionally, exogenous iV-(~-~-ribosyl-5,6-dimethylbenzimidazole rescues the defect of a cobC mutant. We propose that cobC codes for a novel phosphatase whose primary role is in cobalamin biosynthesis. A model for the sequence of biosynthetic steps that assemble the nucleotide loop of cobalamin in s. typhimurium is presented.
Human Immunodeficiency Virus Type 1 Vectors Efficiently Transduce Human Hematopoietic Stem Cells

ABSTRACT Lentiviruses are potentially advantageous compared to oncoretroviruses as gene transfer agents because they can infect nondividing cells. We demonstrate here that human immunodeficiency virus type 1 (HIV-1)-based vectors were highly efficient in transducing purified human hematopoietic stem cells. Transduction rates, measured by marker gene expression or by PCR of the integrated provirus, exceeded 50%, and transduction appeared to be independent of mitosis. Derivatives of HIV-1 were constructed to optimize the vector, and a deletion of most of Vif and Vpr was required to ensure the long-term persistence of transduced cells with relatively stable expression of the marker gene product. These results extend the utility of this lentivirus vector system.
Detecting time-specific differences between temporal nonlinear curves: Analyzing data from the visual world paradigm

In multiple fields of study, time series measured at high frequencies are used to estimate population curves that describe the temporal evolution of some characteristic of interest. These curves are typically nonlinear, and the deviations of each series from the corresponding curve are highly autocorrelated. In this scenario, we propose a procedure to compare the response curves for different groups at specific points in time. The method involves fitting the curves, performing potentially hundreds of serially correlated tests, and appropriately adjusting the overall alpha level of the tests. Our motivating application comes from psycholinguistics and the visual world paradigm. We describe how the proposed technique can be adapted to compare fixation curves within subjects as well as between groups. Our results lead to conclusions beyond the scope of previous analyses.
Feature Engineering for Credit Risk Evaluation in Online P2P Lending

The rise of online P2P lending, as a novel economic lending model, brings new opportunities and challenges for the research of credit risk evaluation. This paper aims to mine information from different data sources to improve the performance of credit risk evaluation models. Be-sides the personal financial and demographic data used in traditional models, the authors collect in-formation from 1 text description, 2 social network and 3 macro-economic data. They de-sign methods to extract features from unstructured data. To avoid the curse of dimensionality caused by too many features and identify the key factors in credit risk, the authors remove the irrelevant and redundant features by feature selection. Using the data provided by Prosper.com, one of the biggest P2P lending platforms in the world, they show that: 1 it can achieve better performance, measured by both AUC area under the receiver operating characteristic curve and classification accuracy, by fusion of information from different data sources; 2 it requires only ten features from different data sources to get better performance.
Bandstop waveguide filters with two or three rejection bands

This paper presents a novel design of bandstop waveguide filters with two or three rejection bands, using quarter-wave resonators. Bandstop waveguide filters are designed using printed-circuit inserts realized with single-mode and multi-mode resonators. The filter response is analyzed depending on the parameters of the resonators and their positions on the printed-circuit insert. Various models of dual-band and triple-band filters are developed by employing different combinations of the resonators, as examples of the proposed multi-band filter design.
Trajectory-Based Design of Robust Non-Fragile Controllers for Uncertain Linear Systems

This paper deals with a design problem of robust non-fragile controllers for uncertain linear systems. The proposed design method of robust non-fragile controllers is based on computation of the trajectory for the uncertain system and differs from the existing methods based on quadratic stabilization via Lyapunov criterion. In this paper, we show that sufficient conditions for asymptotical stability of the uncertain system and a LMI-based design algorithm of a robust non-fragile controller is given. Finally, the effectiveness of the proposed design scheme is shown through illustrative examples
Optimization of Sample Size and Number of Tasks per Respondent in Conjoint Studies Using Simulated Datasets

Because of the increase in computing speed and availability of easy-to-use commercial software for estimating hierarchical Bayesian (HB) models application of these methods became a standard in analyzing choice-based conjoint data. Today market researchers can estimate models of complexity that was not attainable or would require great amount of resources few decades ago. On the other hand it might make many practitioners forget that even the capabilities of HB models are not unlimited and that there are many factors that have a negative impact on the success of the study. This article emphasizes the need to carefully design the study with respect to the sample size and number of tasks shown to the respondents used and recommends checking sufficiency of the setup with use of simulated datasets. These should reflect possible scenarios and impact of various factors.
Building distributed computing abstractions in the presence of mobile byzantine failures. (Construction d'abstraction informatique distribuée en présence de fautes Bizantines mobiles)

In this thesis we consider a model where Byzantine failures are not fixed, we consider the so called Mobile Byzantine failures. So far, only Consensus problem has been solved in presence of Mobile Byzantine failures and interestingly different variations of this failure model have been proposed. For each of them have been proved lower bounds on the number of required processes and have been proposed tight solutions. Our first contribution concerns distributed Registers in such strong model. Distributed Registers are the basic abstraction for Distributed Storages. This advocates our second and main contribution, a general Mobile Byzantine Failure Model. Our main focus is about Distributed Registers, so our third contribution comes, we prove necessities and impossibilities in those models. In particular we prove that is it not possible to solve the weakest register specification in an asynchronous system. On the other side we prove lower bounds for the synchronous system, with respect to the proposed hierarchy models, and tight protocols to solve the Regular Register problem. To conclude, our last contribution is about the Approximate Agreement problem, a weaker form of Consensus. We solve such problem in the same round-based models as Consensus so far. The interesting result is the following, in presence of static Byzantine failures, lower bounds on the number of correct replicas does not change between consensus and approximate agreement. The same invariant still holds in presence of Mobile Byzantine failure. Moreover, along with lower bounds we propose a tight solution to solve approximate agreement.
PCR-based molecular markers linked to the leaf rust resistance gene Lr19 in different bread wheat cultivars

61 varieties of wheat collected in the gene fund of the Research Institute of Crop Husbandry were screened using SCAR-markers associated with the gene of resistance to brown leaf rust, Lr19. As a result of PCR analysis using SCS123 marker the 737 bp locus was detected in 48 genotypes. The expected fragment of the 688 bp was detected in 53 genotypes using the SCS253 marker. The results obtained using both markers indicate that the Lr19 gene is present on 7D chromosomes of 45 genotypes. The existence of the Lr19 gene has not been proven only for 5 from the 61 analyzed wheat genotypes.
Embryo and Developmental Toxicity of Cefazolin Sodium Impurities in Zebrafish

Cefazolin sodium is an essential drug that is widely used in clinical therapy for certain infective diseases caused by bacteria. As drug impurities are considered to be one of the most important causes of drug safety issues, we studied embryotoxicity, cardiotoxicity, and neurotoxicity of nine cefazolin sodium impurities in zebrafish embryo and larvae for the objective control of impurity profiling. LC-MS/MS was employed to analyze the compound absorbance in vivo, and the structure-toxicity relationship was approached. Our results suggested that the structure of MMTD (2-mercapto-5-methyl-1, 3, 4-thiadiazole) is the main toxic functional group for embryo deformities; the 7-ACA (7-aminocephalosporanic acid) structure mainly affects motor nerve function; and both the MMTD and 7-ACA structures are responsible for cardiac effects. Impurity G (7-ACA) presented with the strongest toxicity; impurity A was most extensively absorbed to embryo and larvae; and impurity F (MMTD) exhibited the strongest apparent toxic effect; Therefore, impurities F and G should be monitored from the cefazolin sodium preparations.
The Promise and Pitfalls of Integrated Strategy Instruction

I t is immeasurably easier to oppose and criticize proposals such as that offered by Ellis than it is to propose instructional models in the first instance. Presenting a positive thesis is always an arduous task. Bearing this in mind, I will attempt to offer criticism as well as some direction for ways in which the integrated strategy instruction (ISI) model might be improved. In this way, it is hoped that the criticisms discussed here will also offer an element of a positive thesis. Before detailing more critical remarks, it should be noted that there is much to praise in Ellis's ISI model. The ISI model holds considerable promise for transporting strategy instruction from the resource room to the content area classroom. This transfer, coupled with the general aim of integrating strategy instruction across various curricular areas, is much needed. Ellis has set important and ambitious goals for the ISI model. In a broad sense, it would be difficult to argue against their merit. Ellis carefully details the means of achieving the preceding goals. Here there is much to praise, as well. Ellis relies on current cognitive research on strategy instruction to describe appropriate instructional techniques. Furthermore, the cognitive strategies found in ISI are generally well supported by contemporary research. Thus, much of the following criticism applies to what is not addressed in the ISI model, rather than what Ellis proposes. There are few sins of commission in Ellis's discussion of ISI. There are, however, several important sins of ommission, and the discussion now turns to an examination of the less venial of these.
Model-Free Predictive Current Control for Interior Permanent-Magnet Synchronous Motor Drives Based on Current Difference Detection Technique

A model-free predictive current control (PCC) of interior permanent-magnet synchronous motor (IPMSM) drive systems based on a current difference detection technique is proposed. The model-based PCC (MBPCC) of IPMSM requires knowledge of parameters such as resistance, q-axis inductance, and extended back EMF. This paper develops a new model-free approach that alleviates the need for excessive prior knowledge about the system and only utilizes the stator currents as well as the current differences corresponding to different switching states of the inverter. Despite the salient difference of the proposed approach, it adopts a measure similar to that in the MBPCC approach to obtain the next switching state of the inverter by minimizing a cost function. It is noteworthy that the proposed method is easy to implement due to its simplicity and free of any multiplication operation. For comparison purposes, a digital signal processor, TMS320LF2407, is used to execute the two aforementioned current control techniques. Several experimental results show that the proposed method can significantly improve the current-tracking performance.
