High bandwidth measurement of partial discharge current pulses based on the optimized needle-plate electrode system

In order to obtain the nanosecond partial discharge pulse current signal of needle-plate electrode, a new measurement method of wideband PD pulse current is proposed in this paper. By the numerical calculation of current parameters, the optimized needle-plate electrode structure and the accurate finite element simulation, the experimental platform of the fast PD pulse current detection is set up and its bandwidth is up to 1.81GHz. The testing results indicate that, the established detection system has the some advantages, i.e., high sensitivity, good frequency response characteristics, strong anti-disturbance capability and virtually no waveform distortion, which lays the foundation for further researching the relation between the macroscopic PD pulse current waveform and the microcosmic discharge process.
COMPARISON OF RELATION BETWEEN BODY IMAGE AND SPIRITUAL INTELLIGENCE AMONG MALE AND FEMALE STUDENTS

The purpose of this research is to analyze the relation between body image and spiritual intelligence in Iranian male and female students. The sample includes 376 students at Islamic Azad University, Islamshahr branch which were selected in the stratified and randomly sampling from colleges. The tools include Fisher's body image test and spiritual intelligent SSI-29 questionnaire. The data were analyzed by t test, Pearson correlation and Fisher’s Z test. The relation between spiritual intelligence and Reliance on Internal Core with body image is significant in both genders (p≤0.05). the results show that Understanding and Communication with the Source of Existence in women is higher than men. However, the relation between Understanding and Communication with the Source of Existence with body image in male is significant (p≤0.05) while it is not significant in female students. There are no significant difference between females’ and males’ scores in body image and spiritual intelligence. According to the result, with increasing spiritual intelligence can induce high level of self- awareness and deeper relation with source of existence. As a result, body image can be improved as the important components of mental health.
Determinants of Consumers' E-Loyalty: A Cross-Channel Perspective

Websites are acknowledged as essential to the marketing of brick-and-mortar companies in the maturing e-commerce marketplace. Knowledge of how to position these companies' Websites effectively is thus regarded as essential by scholars and practitioners. By investigating consumer cross-channel behavior, the current study was designed to reveal determinants of consumers' e-loyalty. Two hundred and eighty randomly selected consumers from a top international brick-and-mortar company's customer database participated in an online survey, findings from which indicated that a high level of consumers' brand loyalty in the retail channel not only directly enhances consumers' trust of the same brand's Website, but also directly increases consumers' online brand familiarity and perceived brand reputation, which reinforce consumers' trust in the same brand's Website. Consequently, consumers' e-loyalty toward the same brand's Website is also enhanced. The implications should enable managers to develop Website positioning strategies that leverage their existing brand power in the retail channel.
Design Optimization of Quasi-Active Gate Control for Series-Connected Power Devices

This paper presents a new gate drive circuit for driving a series string of insulated-gate bipolar transistors (IGBTs). The proposed quasi-active gate control (QAGC) circuit is simple to implement as it consists of only a few passive components in addition to a standard gate driver. No separate isolation power supply is required for the upper devices in the stack. The proposed QAGC circuit provides an effective way to drive the power devices and control static and dynamic voltage sharing to the devices at the same time. The theoretical switching operation and the oscillation stability analysis allow criteria for component selection to be established. Limitations of the QAGC circuit are also identified. The modification of the circuit to support more power devices in the series stack is discussed with the aid of the simulation results. The switching operation of the circuit is validated from the experimental results using two IGBTs connected in series. The circuit shows an excellent switching operation with well-controlled dynamic and static voltage sharing and comparable gate voltage between the coupled devices.
Characteristics of an Early Hominid Scavenging Niche [and Comments and Reply]

The characteristics of scavenging opportunities in the Serengeti National Park and Ngorongoro Crater are here documented and applied to the Plio/Pleistocene East Turkana and Olduvai lake basins. The earliest stone-tool-using, meat-eating hominids are argued to have most regularly encountered abandoned felid kills of medium-sized adult herbivores in riparian woodlands during the dry season, kills from which little flesh but all marrow and head contents could have been obtained. Additionally, it is suggested that they may have encountered large quantities of scavengeable flesh if sabertooth predation was concentrated on large herbivores. Such reconstruction of a possible hominid scavenging niche is considered a prerequisite to the development of criteria for the archaeological recognition of scavenging.
Chicken welfare as indicated by lesions on carcases in supermarkets

1. The extent of visible lesions in British broiler carcases was investigated in order to discover the extent of any poor welfare. It is well established that hock burn and some other injuries can occur during housing of broiler chickens, whilst other injuries can occur during handling. 2. Three hundred and eighty-four whole conventionally reared British Farm Standard Grade A chickens were scrutinised in supermarkets to assess the frequency of 15 kinds of lesions. Six lesions were analysed histopathologically and this showed that hock burn would have occurred several days pre-mortem, red alular and wrist bruise were very likely to have occurred pre-mortem, whilst red parson's nose and scratches were likely to have occurred pre-mortem. 3. Many broiler carcases in the supermarkets had dermal lesions: 0·82 had hock burns, 0·45 a red parson's nose, 0·32 a red alular, 0·21 wrist bruises and 0·21 had at least one scratch on a leg. The frequency of the larger hock burns increased with body weight. ‘Organic’ chickens had half as many hock burns as conventionally reared broilers, perhaps because of differences in litter quality or leg strength. 4. The sample studied indicates that painful lesions which would result in poor welfare are frequent in broilers slaughtered in the UK. The Grade A chickens observed exclude birds with obvious visible defects because these birds would have had the blemishes removed and the carcase would have been portioned. Hence the frequencies of lesions in farmed birds would be higher than those reported here.
Statistics at the University of Padua: An Emblematic Journey from the Restoration to the Republican Age

The paper reconstructs the teaching and research activities of scholars in statistics and related subjects at the University of Padua from the Restoration to the Second World War. The history of statistics in Padua is an interesting case study, as it sheds light on the evolution of the discipline at the national level as well as on its relationships with the international development of statistical methods. Some fascinating antecedents go back to the 16th century, with contributions by Gerolamo Cardano and Galileo Galilei. The 150 years from the Restoration to the 1960s are marked by a sequence of phases of renewal and conservatism. At the beginning, the old Statistik took the place of political arithmetic. Statistics experienced telling improvements only with Angelo Messedaglia, who drew from Quetelet and outlined a new political role for the discipline. This led his pupils to view statistics as a social science supporting State intervention, without any methodological peculiarity. A new phase of dramatic innovation was led by Corrado Gini from 1913 to 1925. Again, his pupils and successors exacerbated the neo-descriptive approach of the «Italian school of Statistics», the confrontation with modern statistical inference, and the support to the corporatist programme of the Fascism. This stand largely motivated the post-War decline of the discipline. A new revival had to await the mid-1950s, when Albino Ugge and then Bernardo Colombo started assembling a group of young scholars and planned the establishment of a Faculty of Statistics, achieved in 1968.
On-Chip Multi 4-Port Optical Circulators Volume 6 , Number 1 , February 2014

We present a new geometry for on-chip optical circulators based on waveguide arrays. The optical array is engineered to mimic the Fock space representation of a noninteracting two-site Bose–Hubbard Hamiltonian. By introducing a carefully tailored magnetooptic nonreciprocity to these structures, the array operates in the perfect transfer and surface Bloch oscillation modes in the forward and backward propagation directions, respectively. We show that an array made of ð2N þ 1Þ waveguide channels can function as N 4-port optical circulators with very large isolation ratios and low forward losses. Numerical analysis using beam propagation method indicates a large bandwidth of operation.
Structural and symptomatic change in psychoanalysis and psychodynamic psychotherapy: a quantitative study of process, outcome, and attachment.

This thesis describes a quasi-experimental study exploring psychotherapeutic process and outcome in 25 young adults sequentially assigned to psychoanalysis (n=14) or psychodynamic psychotherapy (n=11) at the Anna Freud Centre in London, England. Analysts reported process using a novel 899-item questionnaire, the Young Adult Weekly Rating Scale (YAWRS). Patients were assessed by an independent psychiatrist at intake, termination, and at 18 month intervals after intake and termination with Main and Goldwyn's Adult Attachment Interview (AAI) and on a host of symptomatic and diagnostic measures. The patients suffered from depression, anxiety, and personality disorders. Over the course of treatment (6 months to 8 years long), 12 of 19 patients (with adequate data) improved symptomatically on an aggregate measure. Ten of 12 improvers were in the psychoanalysis group, suggesting that it is a more effective treatment in this population. Data from 1,314 YAWRS questionnaires were factor analysed and used to test hypotheses from the psychotherapy process literature. In the first year of psychoanalysis (as compared with psychodynamic psychotherapy), higher scores on therapist dynamic technique, patient dynamic material, and negative patient transference were found. In the combined sample, higher scores in the first year on therapist dynamic technique, patient dynamic material, and discussion of contract were predictive of positive outcome. The AAI classifies patients according to security of "state of mind with respect to attachment" from narratives about early life relationship experiences. Our results show a high proportion of secure classifications at initial assessment and, in successful treatments, a movement towards a preoccupied-entangled attachment pattern which began to resolve by termination. We propose that the AAI be used to measure both structural health and regression/transference neurosis, which must occur and then resolve for treatment to succeed. Further research using the YAWRS and AAI is proposed.
Biochemical Characterization of Ribosome Assembly GTPase RbgA in Bacillus subtilis*

Background: RbgA is a GTPase involved in a late assembly step of the 50 S subunit. Results: RbgA is maximally stimulated by 50 S subunits and associates with the ribosome in a nucleotide-dependent manner. Conclusion: Biochemical characterization of RbgA supports that GTPase activity promotes a late step in ribosome assembly and RbgA dissociation. Significance: Learning how RbgA promotes ribosome assembly is critical for understanding how GTPases regulate ribosome biogenesis. The ribosome biogenesis GTPase A protein RbgA is involved in the assembly of the large ribosomal subunit in Bacillus subtilis, and homologs of RbgA are implicated in the biogenesis of mitochondrial, chloroplast, and cytoplasmic ribosomes in archaea and eukaryotes. The precise function of how RbgA contributes to ribosome assembly is not understood. Defects in RbgA give rise to a large ribosomal subunit that is immature and migrates at 45 S in sucrose density gradients. Here, we report a detailed biochemical analysis of RbgA and its interaction with the ribosome. We found that RbgA, like most other GTPases, exhibits a very slow kcat (14 h−1) and has a high Km (90 μm). Homology modeling of the RbgA switch I region using the K-loop GTPase MnmE as a template suggested that RbgA requires K+ ions for GTPase activity, which was confirmed experimentally. Interaction with 50 S subunits, but not 45 S intermediates, increased GTPase activity by ∼55-fold. Stable association with 50 S subunits and 45 S intermediates was nucleotide-dependent, and GDP did not support strong interaction with either of the subunits. GTP and guanosine 5′-(β,γ-imido)triphosphate (GMPPNP) were sufficient to promote association with the 45 S intermediate, whereas only GMPPNP was able to support binding to the 50 S subunit, presumably due to the stimulation of GTP hydrolysis. These results support a model in which RbgA promotes a late step in ribosome biogenesis and that one role of GTP hydrolysis is to stimulate dissociation of RbgA from the ribosome.
The Transformational Leaders' Dimensions and Newcomers' Organizational Socialization Process

Newcomers’ organization assimilation or socialization is a transition process whereby an outsider becomes an insider of an organization. This process involves a lot of change. Four dimensions of transformational leader were suggested to facilitate this change process. The Big Five Model of personality provides insights of the differences on the newcomer’s part. The relationship between the four dimensions of transformational leaders and five newcomers’ personality traits were delineated. Examination of previous literature revealed that transformational leaders gain trust and respect via the first two dimensions, namely charisma and inspiration. Individualized attention should be given high priority for those with neuroticism and extraversion traits. Intellectual stimulation should be given high priority for those with openness to new experience, agreeableness, and conscientiousness traits.
Radiological Assessment of Post Surfactant Changes in Respiratory Distress Syndrome

Seventy three preterm neonates with clinical and radiological evidence of typical RDS having median gestational age 30 weeks and median birth weight 1240 g were studied to evaluate the radiological changes after therapeutic use of surfactant and the value of ultrasound in its screening. The chest radiographs were taken before and 72 hours post surfactant treatment with surfactant application ranging from 1 h to 18 h after birth. 72% cases revealed uniform or asymmetrical extension of pulmonary aeration. Asymmetrical improvement (29%) was seen on the left side right side and usually disappeared within two to five days. 5 neonates (13.5%) showed no change, of which 2 succumbed to death.
Erroneous inflation of diabetes prevalence: Are there global implications?

Comparison of the prevalence of type 2 diabetes mellitus (T2DM) in adults aged 25-64 years in selected Pacific Island countries using whole blood and plasma glucose cut-off points. Unit records of STEPwise approach to Surveillance (STEPS) surveys obtained from Fiji, Samoa, and Tonga Ministries of Health; T2DM prevalence recalculated using whole blood and plasma cut-off points. Shaded bars indicate T2DM prevalence based on correct glucose cut-off points for the glucose meter used (fasting blood glucose [FBG] ≥6.1 mmol/L for early surveys1,3,5 ; fasting plasma glucose [FPG] ≥7.0 mmol/L for later surveys),2,4,6 whereas open bars show T2DM prevalence based on incorrect glucose cut-off points (FPG ≥6.1 mmol/L for later surveys). 2,4,6 Highlights Incorrect glucose cut-off points were applied to the Fiji 2011, Samoa 2013, and Tonga 2012 STEPS surveys. This doubled the actual T2DM prevalences compared to using the correct glucose cut-off points. The errors occurred due to modern glucose meters producing measurements in plasma-equivalent concentrations from whole blood samples. The incorrect whole blood glucose cut-off (≥6.1mmol/L) was applied instead of the correct plasma glucose cut-off (≥7.0mmol/L). This error likely affects other Pacific states, and may have global ramifications.
Selected additives did not improve flowability of DDGS in commercial systems

An experiment was conducted at a commercial, dry-grind ethanol plant to determine if selected additives would improve flowability of dried distillers grains with solubles (DDGS). Main treatment effects were moisture content of DDGS (9 vs. 12% w.b.) and anti-caking agent (ACA). The ACA treatments were: No additive (Control); a moisture migration control agent at 2.5 kg/metric ton (DMX-7); calcium carbonate at 2% w.b. (Calcium carbonate); or a clinoptilolite zeolite at 1.25% w.b. (Zeolite). The ACA were added at the desired level to about 2,275 kg of DDGS using a vertical-screw feed mixer. Batches of DDGS were weighed and loaded into one of eight compartments in an auger-equipped feed truck. After loading, the truck traveled 250 km, sat motionless for at least 60 h, and traveled 250 km back to the ethanol plant. Time required to unload each compartment was recorded. There were no significant interactions between moisture level and ACA for any response criteria. Mean moisture levels were 9% and 11.6% for low and high moisture treatments. Flow rate of DDGS at unloading was higher (P < 0.01) for the 9% compared with 12% moisture level (620 vs. 390 kg/min). Flow rates of DDGS at unloading were: 509 (Control), 441 (DMX-7), 512 (Calcium carbonate), and 558 (Zeolite) kg/min. None of the ACA created flow rates that differed significantly from Control. In conclusion, increasing moisture content from 9% to 11.6% clearly decreased flowability of DDGS. The ACA used in this experiment at the selected concentrations did not improve flowability of DDGS.
Persistent Neural States: Stationary Localized Activity Patterns in Nonlinear Continuous n-Population, q-Dimensional Neural Networks

Neural continuum networks are an important aspect of the modeling of macroscopic parts of the cortex. Two classes of such networks are considered: voltage and activity based. In both cases, our networks contain an arbitrary number, n, of interacting neuron populations. Spatial nonsymmetric connectivity functions represent cortico-cortical, local connections, and external inputs represent nonlocal connections. Sigmoidal nonlinearities model the relationship between (average) membrane potential and activity. Departing from most of the previous work in this area, we do not assume the nonlinearity to be singular, that is, represented by the discontinuous Heaviside function. Another important difference from previous work is that we relax the assumption that the domain of definition where we study these networks is infinite, that is, equal to or . We explicitly consider the biologically more relevant case of a bounded subset of , a better model of a piece of cortex. The time behavior of these networks is described by systems of integro-differential equations. Using methods of functional analysis, we study the existence and uniqueness of a stationary (i.e., time-independent) solution of these equations in the case of a stationary input. These solutions can be seen as persistent; they are also sometimes called bumps. We show that under very mild assumptions on the connectivity functions and because we do not use the Heaviside function for the nonlinearities, such solutions always exist. We also give sufficient conditions on the connectivity functions for the solution to be absolutely stable, that is, independent of the initial state of the network. We then study the sensitivity of the solutions to variations of such parameters as the connectivity functions, the sigmoids, the external inputs, and, last but not least, the shape of the domain of existence of the neural continuum networks. These theoretical results are illustrated and corroborated by a large number of numerical experiments in most of the cases 2 n 3, 2 q 3.
The baryonic branch of Klebanov-Strassler solution: a supersymmetric family of SU(3) structure backgrounds

We exhibit a one-parameter family of regular supersymmetric solutions of type IIB theory that describes the baryonic branch of the Klebanov-Strassler (KS) theory. The solution is obtained by applying the supersymmetry conditions for SU(3)-structure manifolds to an interpolating ansatz proposed by Papadopoulos and Tseytlin. Other than at the KS point, the family does not have a conformally-Ricci-flat metric, neither it has self-dual three-form flux. By varying also the string coupling, our solution smoothly interpolates between Klebanov-Strassler and Maldacena-Nu? ez (MN). The asymptotic IR and UV are that of KS throughout the interpolating flow, except for the extremal value of the parameter where the UV solution drastically changes to MN.
p53-dependent Caspase-2 Activation in Mitochondrial Release of Apoptosis-inducing Factor and Its Role in Renal Tubular Epithelial Cell Injury*

We demonstrate the role of p53-mediated caspase-2 activation in the mitochondrial release of apoptosis-inducing factor (AIF) in cisplatin-treated renal tubular epithelial cells. Gene silencing of AIF with its small interfering RNA (siRNA) suppressed cisplatin-induced AIF expression and provided a marked protection against cell death. Subcellular fractionation and immunofluorescence studies revealed cisplatin-induced translocation of AIF from the mitochondria to the nuclei. Pancaspase inhibitor benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone or p53 inhibitor pifithrin-α markedly prevented mitochondrial release of AIF, suggesting that caspases and p53 are involved in this release. Caspase-2 and -3 that were predominantly activated in response to cisplatin provided a unique model to study the role of these caspases in AIF release. Cisplatin-treated caspase-3 (+/+) and caspase-3 (-/-) cells exhibited similar AIF translocation to the nuclei, suggesting that caspase-3 does not affect AIF translocation, and thus, caspase-2 may be involved in the translocation. Caspase-2 inhibitor benzyloxycarbonyl-Val-Asp-Val-Ala-Asp-fluoromethylketone or down-regulation of caspase-2 by its siRNA significantly prevented translocation of AIF. Caspase-2 activation was a critical response from p53, which was markedly induced and phosphorylated in cisplatin-treated cells. Overexpression of p53 not only resulted in caspase-2 activation but also mitochondrial release of AIF. The p53 inhibitor pifithrin-α or p53 siRNA prevented both cisplatin-induced caspase-2 activation and mitochondrial release of AIF. Caspase-2 activation was dependent on the p53-responsive gene, PIDD, a death domain-containing protein that was induced by cisplatin in a p53-dependent manner. These results suggest that caspase-2 activation mediated by p53 is an important pathway involved in the mitochondrial release of AIF in response to cisplatin injury.
