High-Quality Draft Genome Sequence of Burkholderia contaminans CH-1, a Gram-Negative Bacterium That Metabolizes 2-Azahypoxanthine, a Plant Growth-Regulating Compound

ABSTRACT Burkholderia contaminans strain CH-1 converts 2-azahypoxnathine to 2-aza-8-oxohypoxanthine, plant growth-regulating compounds, by oxidation. We report here the high-quality draft genome sequence of B. contaminans CH-1. The genome contains 8,065 protein-coding sequences, including several genes possibly involved in metabolizing 2-azahypoxanthine.
Impaired Recency Judgments and Intact Novelty Judgments after Fornix Transection in Monkeys

Over four experiments based on the delayed matching-to-sample task, fornix-transected and normal control monkeys were presented with a sequence of five sample stimuli and then received intermixed within-session recency (WSR) and between-session recency (BSR) tests in experiment 1, only BSR tests in experiment 2, only absolute novelty (AN) tests in experiment 3, or only WSR tests in experiment 4. In WSR tests, monkeys chose which of two samples had occurred more recently in the immediately preceding sequence. In BSR and AN tests, monkeys were required to choose one sample from the immediately preceding sequence in preference to a foil unseen in the present session (BSR) or an AN foil that had never been presented before. When tests of WSR and BSR were intermixed (experiment 1), fornix monkeys performed below the level of the control monkeys in both types of test, although this difference was not statistically significant. In experiment 2, fornix monkeys were significantly impaired on tests of BSR alone, in which memory for a stimulus presented in an immediately preceding sequence could compete with memory for a foil presented in an earlier training session. In tests of AN (experiment 3), fornix monkeys performed at the same level as control animals in distinguishing a previously experienced stimulus from a previously unseen foil. In experiment 4, fornix transection significantly impaired tests of WSR alone. Taken together, these results suggest that one specialized role of the fornix is to process temporal information.
Towards development of link-based robotic dolphin: Experiences and lessons

This paper focuses on technical endeavors to develop bio-inspired dolphin-like robots, involving dynamic modeling, mechanical design, as well as motion control. The inspiration and motivation comes from the remarkable swimming abilities of dolphins together with some promising applications in aquatic environments. The thrust in dolphin-like movements in a robotics context can be generated by the up-down-motioned fluke, while the turning is achieved by left-right-sided deflections. Based upon three generations of link-based robotic prototypes, experiences and lessons accumulated in the course of producing these accomplishments are summarized, which provide insight into unraveling the efficient and agile propulsive mechanisms associated with Gray's paradox. Comparative results are finally offered to demonstrate significant differences between biological dolphin and actual robots.
REEF: Retainable Evaluator Execution Framework

Resource Managers like Apache YARN have emerged as a critical layer in the cloud computing system stack, but the developer abstractions for leasing cluster resources and instantiating application logic are very low-level. This flexibility comes at a high cost in terms of developer effort, as each application must repeatedly tackle the same challenges (e.g., fault-tolerance, task scheduling and coordination) and re-implement common mechanisms (e.g., caching, bulk-data transfers). This paper presents REEF, a development framework that provides a control-plane for scheduling and coordinating task-level (data-plane) work on cluster resources obtained from a Resource Manager. REEF provides mechanisms that facilitate resource re-use for data caching, and state management abstractions that greatly ease the development of elastic data processing work-flows on cloud platforms that support a Resource Manager service. REEF is being used to develop several commercial offerings such as the Azure Stream Analytics service. Furthermore, we demonstrate REEF development of a distributed shell application, a machine learning algorithm, and a port of the CORFU [4] system. REEF is also currently an Apache Incubator project that has attracted contributors from several instititutions.1 http://reef.incubator. apache.org
Attachment and Borderline Personality Disorder

The author outlines his concept of reflective function or mentalization, which is defined as the capacity to think about mental states in oneself and in others. He presents evidence to suggest that the capacity for reflective awareness in a child's caregiver increases the likelihood of the child's secure attachment, which in turn facilitates the development of mentalization in the child. He proposes that a secure attachment relationship offers the child a chance to explore the mind of the caregiver, and in this way to learn about minds; he formulates this model of the birth of the psychological self as a variation on the Cartesian cogito: `My caregiver thinks of me as thinking and therefore I exist as a thinker. ` This model is then applied to provide insight into some personality-disordered individuals who were victims of childhood abuse. The author proposes (1) that individuals who experience early trauma may defensively inhibit their capacity to mentalize to avoid having to think about their caregiver's wish to harm them; and (2) that some characteristics of severe borderline personality disorder may be rooted in developmental pathology associated with this inhibition. He offers evidence for and some qualifications of this model, and argues that the therapeutic effect of psychoanalysis depends on its capacity to activate patients' ability to evolve an awareness of mental states and thus find meaning in their own and other people's behavior.
Five-Phase Interior Permanent-Magnet Motors With Low Torque Pulsation

High torque pulsation is a major disadvantage of most interior permanent-magnet (IPM) motor configurations. Choosing the proper number of stator slots and winding distribution as well as increasing number of phases are among the possible solutions for reducing torque pulsation. In this paper, five-phase IPM motor with fractional-slot stator is studied. It is shown that despite other IPM motors, the new five-phase IPM motor with fractional slot has a very low torque pulsation. For comparison purposes, a five-phase IPM motor with common configuration is also considered. It is shown that the torque pulsation of the proposed fractional-slot five-phase IPM motor is much lower than the conventional five-phase IPM motor. Nonlinear finite-element method is used to analyze different machine configurations. A prototype four-pole five-phase IPM motor with 15 stator slots has been built and is used for experimental verification
Holarchic Analysis of Livestock Farming Systems in the US Midwest

The idea of agroecosystem analysis has at least some roots in the frustration of researchers who saw their technological innovations too often ignored by farmers (Conway 1985;1986;1987). This led to a “systems” approach manifested in a variety of ways, but generally with a strong measure of farmer participation. The “Conway school” and most other systematic approaches to analyzing agroecosystems ultimately seek normative assessments, for comparisons among extant systems and with imaginable alternatives. However, such normative assessments quickly come into conflict with the morass of judgments that challenge the broader task of defining sustainability, i.e., “for whom, for how long, and at what cost? ” (Allen, et al. 2003). Clashes of values and temporal horizons arise in the full range of agricultural situations, from the towns of Wisconsin, U.S.A. to the highlands of Vietnam.
Efficient estimation of density and probability of large deviations of sum of IID random variables

We consider the problem of efficient simulation estimation of the density function at the tails, and the probability of large deviations for an average of independent, identically distributed light-tailed random variables. The latter problem has been extensively studied in literature where state independent exponential twisting based importance sampling has been shown to be asymptotically efficient and a more nuanced state dependent exponential twisting has been shown to have a stronger bounded relative error property. We exploit the saddle-point based representations that exist for these rare quantities, which rely on inverting the characteristic functions of the underlying random variables. We note that these representations reduce the rare event estimation problem to evaluating certain integrals, which may via importance sampling be represented as expectations. Further, it is easy to identify and approximate the zero-variance importance sampling distribution to estimate these integrals. We identify such approximating importance sampling measures and argue that they possess the asymptotically vanishing relative error property.
Design optimization for cogging torque minimization and efficiency maximization of a high-speed PM motor

This paper presents a 3-phase, 400 W, 14000 rpm, 2-pole/3-slot non-overlapping windings PM motor. In the design of the motor, Taguchi parameter method coupled with the finite element method (FEM) analysis is employed to minimize the level of cogging torque and maximize the efficiency of the motor. A mechanical analysis is carried out to investigate the mechanical feasibility of the rotor due to high-speed rotation, and a thermal analysis is conducted to obtain the temperature distributions within the motor. Test results from a prototype motor demonstrate that the motor is favorable regarding cogging torque minimization and efficiency maximization.
Mupirocin for preventing exit-site infection and peritonitis in patients undergoing peritoneal dialysis.

OBJECTIVES Recently, there have been increasing concerns about the emergence of mupirocin resistance and increased infections due to lowered inhibition of Staphylococcus aureus. We conducted this systemic analysis to find out whether the application of mupirocin was effective for the prevention of exit-site infection (ESI) and peritonitis in patients undergoing peritoneal dialysis (PD). METHODS Recruited studies met the following criteria: they were randomized controlled trials or historical cohort studies; subjects consisted of adults (age, >or= 18 years) undergoing PD; mupirocin treatment was administered to the therapy group and placebo or no treatment was administered to the control group. The primary extracted data were the difference in the episodes of ESI and peritonitis S. aureus or other organisms among treatment and control groups. Results. Fourteen studies described in 13 articles and a total of 1,233 patients versus 1,217 controls were included in the analysis. Of the 13 articles, 6 were newly published articles that had not been analysed previously and 3 were randomized controlled trials. The application of mupirocin decreased the risk by 72% [95% confidence interval (CI): 0.60-0.81] in ESI and by 70% (95% CI 0.52-0.81) in peritonitis due to S. aureus among all patients undergoing PD. Treatment of mupirocin reduced the risks of ESI and peritonitis due to all organisms by 57% (95% CI: 0.46-0.66) and 41% (95% CI: 0.24-0.54), respectively. Based on the six newly published articles, the reduced risk rate for mupirocin therapy was found to be 80% (95% CI: 0.39-0.93, P = 0.004) in ESI and 91% (95% CI: 0.72-0.97, P < 0.0001) in peritonitis due to S. aureus; 70% (95% CI: 0.47-0.82, P < 0.0001) in ESI and 42% (95% CI: 0.25-0.55, P < 0.0001) in peritonitis due to all organisms among mupirocin-treated and -untreated subjects. Based on the three randomized controlled trials, ESI and peritonitis due to S. aureus were found to be reduced by 73% (95% CI: 0.63-0.80, P < 0.0001) and 40% (95% CI: 0.17-0.56, P = 0.002), respectively. Interestingly, although mupirocin treatment can reduce the risk rate of ESI by 46% (95% CI: 0.35-0.55, P < 0.00001), it cannot decrease the risk rate of peritonitis due to all organisms (P = 0.56). CONCLUSIONS Mupirocin prophylaxis was effective on preventing ESI and peritonitis due to S. aureus and other organisms in PD patients.
Applicability of identity-based cryptography for disruption-tolerant networking

Traditional approaches for communication security do not work well in disruption- and delay-tolerant networks (DTNs). Recently, the use of identity-based cryptography (IBC) has been proposed as one way to help solve some of the DTN security issues. We analyze the applicability of IBC in this context and conclude that for authentication and integrity, IBC has no significant advantage over traditional cryptography, but it can indeed enable better ways of providing confidentiality. Additionally, we show a way of bootstrapping the needed security associations for IBC use from an existing authentication infrastructure.
Spreadsheet as a relational database engine

Spreadsheets are among the most commonly used applications for data management and analysis. Perhaps they are even among the most widely used computer applications of all kinds. However, the spreadsheet paradigm of computation still lacks sufficient analysis. In this paper we demonstrate that a spreadsheet can play the role of a relational database engine, without any use of macros or built-in programming languages, merely by utilizing spreadsheet formulas. We achieve that by implementing all operators of relational algebra by means of spreadsheet functions. Given a definition of a database in SQL, it is therefore possible to construct a spreadsheet workbook with empty worksheets for data tables and worksheets filled with formulas for queries. From then on, when the user enters, alters or deletes data in the data worksheets, the formulas in query worksheets automatically compute the actual results of the queries. Thus, the spreadsheet serves as data storage and executes SQL queries, and therefore acts as a relational database engine. The paper is based on Microsoft Excel (TM), but our constructions work in other spreadsheet systems, too. We present a number of performance tests conducted in the beta version of Excel 2010. Their conclusion is that the performance is sufficient for a desktop database with a couple thousand rows.

The research paper briefs about the implementation of screen readers for Marathi in Windows and Linux platform using unrestricted domain Marathi Text To Speech with Indian English support. The application is an integration of MTTS with open source Screen readers NVDA and ORCA. MTTS is a syllable based unit selection concatenative system, built around open source festival engine. IE support is provided for the smooth navigation and handling the English words occurring while accessing internet and other applications. The TTS is a concatenative based system in which syllable is the highest unit for concatenation. The TTS output resembles natural human voice since it uses the original speech segments for concatenation. Testing has been done with normal and differently abled users. Tuning of the system for improving the user friendliness has been done based on the feedback from the DA The system gets a Mean Opinion Score of 86.4% when evaluated by a group of DA.
Measuring inter-hemispheric integration in bipolar affective disorder using brain network analyses and HARDI

Bipolar disorder is characterized by extreme mood swings, including both manic and depressive episodes commonly accompanied by psychosis. Many imaging studies have investigated white matter changes in bipolar illness, and the results have suggested abnormal intra- and inter-hemispheric white matter structures, particularly in the fronto-limbic and callosal systems. However, some inconsistency remains in the literature, and no study to-date has utilized brain network analysis using graph theory. Here, we acquired 64-direction diffusion weighted imaging (DWI) on 25 euthymic bipolar I subjects and 25 gender/age matched healthy subjects. White matter integrity measures were computed and compared in 50 white matter ROIs. The results indicated impaired integrity in the corpus callosum. Guided by this, we constructed whole brain structural connectivity networks using graph theory. We devised brain network metrics (inter-hemispheric path length and efficiency) to further probe inter-hemispheric integration, and demonstrated relatively preserved intra-hemispheric but significantly impaired inter-hemispheric integration in our bipolar subjects.
Simulation Run Length Planning

To design a stochastic simulation experiment, it is helpful to have an estimate of the simulation run lengths required to achieve desired statistical precision. Preliminary estimates of required run lengths can be obtained by approximating the stochastic model of interest by a more elementary Markov model that can be analyzed analytically. When steady-state quantities are to be estimated by sample means, we often can estimate required run lengths by calculating the asymptotic variance and the asymptotic bias of the sample mean in the Markov model.
Efficacy and safety of topical ciprofloxacin/dexamethasone versus neomycin/polymyxin B/ hydrocortisone for otitis externa

SUMMARY Objectives: To compare the efficacy and safety of ciprofloxacin 0.3%/dexamethasone 0.1% (CIP/DEX) otic suspension with that of neomycin 0.35%/polymyxin B 10 000 IU/mL/hydrocortisone 1.0% (N/P/H) otic suspension in patients with acute otitis externa (AOE). Study Design: Randomized, observer-masked, parallel-group, multicenter study. Patients were randomized to 7 days treatment with either CIP/DEX 3–4 drops twice daily or N/P/H 3–4 drops three times daily. Population: Patients of either sex and older than 1 year, with a clinical diagnosis of mild, moderate, or severe AOE and intact tympanic membranes were recruited to participate. Outcomes Measured: Signs and symptoms of AOE, including ear inflammation, tenderness, edema and discharge (assessed on Days 3, 8 [End-of-Therapy] and 18 [Test-of-Cure]); microbiologic eradication (presumed or documented); and frequency of adverse events. Results: Patients enrolled numbered 468. In culture-positive patients who met the inclusion criteria (N = 396), clinical cure rates at Day 18 were significantly higher with CIP/DEX than with N/P/H (90.9% vs. 83.9%; p = 0.0375), as were microbiologic eradication rates (94.7% vs. 86.0%; p = 0.0057). In addition, the clinical response was significantly better with CIP/DEX than with N/P/H at Days 3 and 18 (p = 0. 0279 and p = 0. 0321, respectively), as was the reduction in ear inflammation at Day 18 (p = 0.0268). Both preparations were well tolerated in pediatric and adult patients. Conclusions: 7 days treatment with CIP/DEX otic suspension administered twice daily is clinically and microbiologically superior to N/P/H otic suspension administered 3 times daily in the treatment of mild to severe AOE, and is equally well tolerated.
Transplantation of Clonal Neural Precursor Cells Derived from Adult Human Brain Establishes Functional Peripheral Myelin in the Rat Spinal Cord

We examined the myelin repair potential of transplanted neural precursor cells derived from the adult human brain from tissue removed during surgery. Sections of removed brain indicated that nestin-positive cells were found predominantly in the subventricular zone around the anterior horns of the lateral ventricle and in the dentate nucleus. Neurospheres were established and the nestin-positive cells were clonally expanded in EGF and bFGF. Upon mitogen withdrawal in vitro, the cells differentiated into neuron- and glia-like cells as distinguished by antigenic profiles; the majority of cells in culture showed neuronal and astrocytic properties with a small number of cells showing properties of oligodendrocytes and Schwann cells. When transplanted into the demyelinated adult rat spinal cord immediately upon mitogen withdrawal, the cells elicited extensive remyelination with a peripheral myelin pattern similar to Schwann cell myelination characterized by large cytoplasmic and nuclear regions, a basement membrane, and P0 immunoreactivity. The remyelinated axons conducted impulses at near normal conduction velocities. This suggests that a common neural progenitor cell for CNS and PNS previously described for embryonic neuroepithelial cells may be present in the adult human brain and that transplantation of these cells into the demyelinated spinal cord results in functional remyelination.
Analysis of Low Complexity Max Log MAP Detector and MMSE Detector for Interference Suppression in Correlated Fading

Performance of future wireless communication systems being interference limited, researchers are focusing on interference alignment, interference mitigation and interference suppression to diminish, manage or exploit these interferers. In this paper, we carry out the performance analysis of the recently proposed low complexity max log MAP detector and linear MMSE detector for interference suppression under the realistic conditions of correlated fading in cellular environment. We assume only receive correlation as base stations (BSs) due to their extended separation are likely to be uncorrelated. However the intricacy of realizing requisite antenna spacing in the mobile station (MS) combined with the lack of scattering would instigate the individual antennas at MS to be correlated. Employing moment generating function (MGF)-based approach, we derive upper bounds of coded pairwise error probability (PEP) and study the degrading effect of correlation on both the detectors.
Experimental study on the impact of vehicular obstructions in VANETs

Channel models for vehicular networks typically disregard the effect of vehicles as physical obstructions for the wireless signal. We aim to clarify the validity of this simplification by quantifying the impact of obstructions through a series of wireless experiments. Using two cars equipped with Dedicated Short Range Communications (DSRC) hardware designed for vehicular use, we perform experimental measurements in order to collect received signal power and packet delivery ratio information in a multitude of relevant scenarios: parking lot, highway, suburban and urban canyon. Upon separating the data into line of sight (LOS) and non-line of sight (NLOS) categories, our results show that obstructing vehicles cause significant impact on the channel quality. A single obstacle can cause a drop of over 20 dB in received signal strength when two cars communicate at a distance of 10 m. At longer distances, NLOS conditions affect the usable communication range, effectively halving the distance at which communication can be achieved with 90% chance of success. The presented results motivate the inclusion of vehicles in the radio propagation models used for VANET simulation in order to increase the level of realism.
