Modeling of Magnetized Graphene From Microwave to THz Range by DGTD With a Scalar RBC and an ADE

This paper presents a discontinuous Galerkin time-domain (DGTD) method for the transient analysis of magnetized graphene from the microwave to terahertz (THz) frequencies. By considering the atom thick graphene layer as an infinitely thin conductive sheet with finite surface conductivity, a frequency-dependent anisotropic resistive boundary condition (RBC) is obtained. Based on this RBC, the direct volumetric discretization of graphene layer is avoided. Instead of directly deriving the numerical flux for DGTD considering the presence of this anisotropic and dispersive RBC, an auxiliary surface polarization current governed by a first-order time-dependent partial differential equation (PDE) is introduced over the graphene with the purpose to obtain an isotropic and simultaneously nondispersive RBC. In this way, the new formulated numerical flux expression derived from the Rankine-Hugoniot jump relations is isotropic, and no time-domain convolution is involved in the finalized matrix equations. To verify the applicability and accuracy of the proposed algorithm, the Faraday rotation and the surface plasmon resonance of a plane wave through magnetically biased graphene are investigated. For open-region scattering problems, a hybrid DGTD and time-domain boundary integral (TDBI) method is applied to rigorously truncate the computational domain.
Social and Physical Aspects of the Service Encounter: Effects on Trust and Customer Loyalty to the Service Provider

The purpose of this research is to evaluate the influence of two strategic service encounter dimensions on consumer beliefs and service loyalty. A conceptual model was generated with the aim of seeking to reveal the contribution of the physical environment and social interactions with front line employees on customer's evaluation of the service provider and loyalty. An empirical study is conducted based on a sample of 400 customers of fitness centers. Collected data was analyzed using a structural modeling that highlight the contribution of each predictors. The results revealed that physical and social cues differently influence customer trust and loyalty to the service provider. It seems that social interactions are more effective in building customer trust. Overall, the joint effect of servicescape and social relationships positively influence customer trust and lead to service loyalty. This paper provides empirical evidence on the contribution of two service encounter cues: servicescape and social interaction on customer trust and service loyalty. The research offers a conceptual framework that can be tested in a variety of services. Managerial recommendations focus on improving relational aptitudes of frontline employees, mainly in personal services such as fitness centers.
Une approche générique pour l'adaptation dynamique des IHM au contexte

The contexts of use vary a lot. It becomes fundamental to adapt user interfaces (UI) to the context. In this article, we choose an approach based on models for UI adaptation. Our approach facilitates the adaptation through a generic and flexible specification of the task tree model. This specification takes into account both similarities and existent variations between different users contexts of the same application. Such models are afterwards adjusted by model transformation such as the Model Driven Engineering (MDE [6]), according to the user situation.
The Effect of National Culture on

Studies on the adoption of innovations by companies generally include micro-level and meso-level variables. This study adds to the literature by investigating the role of national culture (i.e. a macro-level variable) to explain differences in adoption rates across countries. In particular, we investigate the effects of the five Hofstede culture dimensions and the culture dimensions proposed by Hall on country adoption rates. Hypothesized effects were tested using a large-scale empirical study concerning the adoption of Enterprise Resource Planning (ERP) software by mid-size companies covering ten European countries. Results indicate that variables describing national culture have a significant influence on the country adoption rates.
Alternative methods for assessing bronchodilator reversibility in chronic obstructive pulmonary disease

BACKGROUND Bronchodilator reversibility testing is recommended in all patients with chronic obstructive pulmonary disease (COPD) but does not predict improvements in breathlessness or exercise performance. Two alternative ways of assessing lung mechanics—measurement of end expiratory lung volume (EELV) using the inspiratory capacity manoeuvre and application of negative expiratory pressure (NEP) during tidal breathing to detect tidal airflow limitation—do relate to the degree of breathlessness in COPD. Their usefulness as end points in bronchodilator reversibility testing has not been examined. METHODS We studied 20 patients with clinically stable COPD (mean age 69.9 (1.5) years, 15 men, forced expiratory volume in one second (FEV1) 29.5 (1.6)% predicted) with tidal flow limitation as assessed by their maximum flow-volume loop. Spirometric parameters, slow vital capacity (SVC), inspiratory capacity (IC), and NEP were measured seated, before and after nebulised saline, and at intervals after 5 mg nebulised salbutamol and 500 μg nebulised ipratropium bromide. The patients attended twice and the treatment order was randomised. RESULTS Mean FEV1, FVC, SVC, and IC were unchanged after saline but the degree of tidal flow limitation varied. FEV1 improved significantly after salbutamol and ipratropium (0.11 (0.02) l and 0.09 (0.02) l, respectively) as did the other lung volumes with further significant increases after the combination. Tidal volume and mean expiratory flow increased significantly after all bronchodilators but breathlessness fell significantly only after the combination treatment. The initial NEP score was unrelated to subsequent changes in lung volume. CONCLUSIONS NEP is not an appropriate measurement of acute bronchodilator responsiveness. Changes in IC were significantly larger than those in FEV1and may be more easily detected. However, our data showed no evidence for separation of “reversible” and “irreversible” groups whatever outcome measure was adopted.
HOW CAN A LEADER GUIDE OUR SEARCH FOR THE HOLY GRAIL? THE LONGITUDINAL RELATIONSHIP BETWEEN SATISFACTION AND PERFORMANCE AND THE IMPACT OF LEADER BEHAVIORS

Coined the ‘Holy Grail’ of organizational behavior (Landy, 1989), researchers and laypeople alike have been fascinated with the link between employee satisfaction and performance. While meta-analyses have in fact demonstrated a link between the two (e.g. Judge et al., 2001), the directionality of this relationship and the contextual factors that influence the relationship are still in question. Therefore, the current paper revisits and extends this question by (1) investigating the causal direction between satisfaction and performance at the store level of analysis across multiple stores of a single organization, (2) looking at two specific performance measures that are practically important (store profitability and customer-related performance), and (3) examining the contextual factor of leadership to understand its impact on the satisfaction-performance relationship. Data was collected from 328 stores within a large retail organization over the course of two years (2003 and 2004). Results suggested a significant causal relationship between stores’ employee satisfaction at time 1 and stores’ customer-related performance dimensions at time 2. However, no significant relationships were found between stores’ financial performance at time 1 and stores’ employee satisfaction at time 2. Further, leader behaviors did not moderate these relationships. Interestingly, however, leader behaviors positively impacted stores’ employee satisfaction, which caused an increase in customer-related performance measures, which positively related to stores’ financial performance. Implications of these causal findings are discussed.
The application of observability analysis in stationary base

The Kalman filter bases on stochastic conformance controllability and observability, and has been widely used in fine alignment of SINS stationary base. The observability analysis could guide the design of Kalman filter to improve the precision of the fine alignment. According to the state equation of the fine alignment stationary and the studies of predecessors, a specific engineering solution is proposed to study the observability of fine alignment in SINS stationary base.
Bcl-2 Controls Caspase Activation Following a p53-dependent Cyclin D1-induced Death Signal*

MCF-7 and ZR-75 breast cancer cells infected with an adenovirus constitutively expressing high levels of cyclin D1 demonstrated widespread mitochondrial translocation of Bax and cytochrome c release that was approximately doubled after the addition of all-trans retinoic acid (RA) or Bcl-2 antisense oligonucleotide. By comparison, the percentage of cells in Lac Z virus-infected cultures containing translocated Bax and cytoplasmic cytochrome c was markedly less even after RA treatment. Despite this, RA-treated Lac Z and untreated cyclin D1 virus-infected cultures contained similarly low proportions of cells with active caspase or cells that were permeable to propidium iodide. Bax activation was p53-dependent and accompanied by arrest in G2 phase. Although constitutive Bcl-2 expression prevented Bax activation, it did not alter cyclin D1-induced cell cycle arrest, illustrating the independence of these events. Both RA and antisense Bcl-2 oligonucleotide decreased Bcl-2 protein levels and markedly increased caspase activity and apoptosis in cyclin D1-infected cells. Thus amplified cyclin D1 expression initiates an apoptotic signal inhibited by different levels of cellular Bcl-2 at two points. Whereas high cellular levels of Bcl-2 prevent mitochondrial Bax translocation, lower levels can prevent apoptosis by inhibition of caspase activation.
Reservoir characterization and inversion uncertainty via a family of particle swarm optimizers

History matching provides to reservoir engineers an improved spatial distribution of physical properties to be used in forecasting the reservoir response for field management. The ill-posed character of the history-matching problem yields nonuniqueness and numerical instabilities that increase with the reservoir complexity. These features might cause local optimization methods to provide unpredictable results not being able to discriminate among the multiple models that fit the observed data (production history). Also, the high dimensionality of the inverse problem impedes estimation of uncertainties using classical Markov-chain Monte Carlo methods. We attenuated the ill-conditioned character of this history-matching inverse problem by reducing the model complexity using a spatial principal component basis and by combining as observables flow production measurements and time-lapse seismic crosswell tomographic images. Additionally the inverse problem was solved in a stochastic framework. For this purpose,.
Congestion effects on regional & system emission and consumers allocated cost

This paper considers the congestion effects on emission and consumers' allocated cost. In order to consider some environmental and operational effects of congestion, an environmental constrained active-reactive optimal power flow (AROPF) considering capability curve is presented. On outage conditions, the total cost of the system will increase. On the other hand in power systems, the operating cost and system emission have conflicted objectives, then it may be concluded that the outage in the system may lead to a total emission decrease. In this paper the famous Aumann-Shapley method is used as a pricing methodology. Two case studies such as 14-bus and 118-bus IEEE test systems are conducted. Results demonstrate that, although the line outage in power systems leads to increase the total cost, the amount of emission depending on the place where the outage occurs can be more than, less than or equal to the normal conditions' emission. Also results show that although from power sellers' standpoint the well-known Aumann-Shapley method is a precise pricing method to cover the incurred cost with an acceptable error that can show the real effect of congestion on consumers' cost, from consumers' standpoint it is not a good method for cost allocation, because some consumers will face with an increase in cost and the others will face with a decrease on their cost.
INVESTOR DEMAND, SIZE EFFECT AND THE IMMEDIATE POST-LISTING BEHAVIOR OF MALAYSIAN IPOs

This paper examines the issues of investor demand and size effect in trying to explain the underpricing phenomenon in IPOs in an emerging capital market, as well as and their effect on the immediate post-listing behavior of IPOs, using a sample of 277 Malaysian IPOs from January 2004 to December 2010. The result shows that the average initial return of IPOs listed on the ACE market of Bursa Malaysia is significantly higher than the average of those IPOs listed on the Main Market, an indication that size effect plays an important role in explaining the under-pricing phenomenon in Malaysian IPOs. The significantly positive correlation between the over-subscription ratio and the first day price spread suggests the existence of a demand effect, especially with the non-private placement IPOs. The finding also indicates that investor demand does have a direct relation with price spread during the immediate post-listing trading activity.

The RovA regulons of Yersinia enterocolitica and Yersinia pestis are distinct: evidence that many RovA‐regulated genes were acquired more recently than the core genome

RovA is a transcriptional activator of Yersinia invasin, an outer membrane protein involved in bacterial attachment and invasion across the intestinal epithelium. In Y. enterocolitica, a rovA mutant is attenuated for virulence compared with either wild‐type or inv mutant strains, indicating that RovA may regulate additional virulence factors. Here, we used microarray analysis to define the RovA regulon. Curiously, there was little overlap between the RovA regulons of Y. enterocolitica and Y. pestis despite the fact that RovA itself is highly conserved between the two species. Some of these differences are explained by the observation that a number of RovA‐regulated loci in Y. enterocolitica do not have orthologues in Y. pestis and vice versa, suggesting that RovA established regulatory control over genetic material acquired after the divergence of the species. Electromobility shift assays demonstrated that 15 of these RovA‐regulated loci directly interact with RovA, and 11 of these promoters had similar affinity as observed for the inv promoter. H‐NS and YmoA are believed to form a transcriptional repression complex on the inv promoter, and several studies indicate that RovA and H‐NS have overlapping DNA binding sites. H‐NS and YmoA regulated a subset of the RovA‐regulated loci. Furthermore, H‐NS directly bound to 14 of the 15 promoters bound by RovA. From these data, we hypothesize that RovA generally behaves as an anti‐H‐NS factor to alleviate transcriptional repression in Y. enterocolitica. A number of recent studies have presented data and a model suggesting that H‐NS functions as a transcriptional silencer of horizontally acquired genes. This repression can be selectively relieved by regulators such as RovA, and the observation that nearly all RovA‐activated genes are repressed by H‐NS is consistent with this model.
Performance Analysis of Carrier-Based Discontinuous PWM Method for Vienna Rectifiers With Neutral-Point Voltage Balance

The nongenerative-boost type rectifier, which is called the Vienna rectifier, is advantageous in terms of efficiency and current total harmonic distortion. Therefore, the Vienna rectifier is used in grid-connected applications such as telecommunication systems and wind turbine systems. Owing to the structural characteristics of the Vienna rectifier, various switching methods exist. Among these methods, a carrier-based discontinuous pulse-width modulation (CB-DPWM) method guarantees high efficiency compared to continuous pulse-width modulation methods; moreover, it is simple compared to a DPWM method based on space vectors. In this paper, the performance of the CB-DPWM method, its applicable region depending on the power factor and modulation index (Ma), and its efficiency are analyzed in detail. Then, based on the analysis, a neutral-point voltage balancing method for the CB-DPWM method is proposed. The effectiveness and performance of the proposed neutral-point voltage balancing method are verified by simulation and experiment.
The grid protocol: a high performance scheme for maintaining replicated data

A protocol for maintaining replicated data that can provide both high data availability and low response time is presented. Existing protocols are designed primarily to achieve high availability by updating a large fraction of the copies, which provides some (although not significant) load sharing. In the new protocol, transaction processing is shared effectively among nodes storing copies of the data, and both the response time experienced by transactions and the system throughput are improved significantly. Also presented is an analysis of the availability of the new protocol and simulation is used to study the effect of load sharing on the response time of transactions. The new protocol is also compared with a voting-based scheme. <<ETX>>

Cruisers on the Danube - the impact of LMX theory on job satisfaction and employees’ commitment to organization

In the early 21 st century, tourist cruises along the Danube River (Corridor 7) experience significant expansion. The main task of cruise companies is the satisfaction of guests, which primarily depends on employee satisfaction affected by numerous organizational factors, including the relationship between the employee and the manager as one of the most important. The aim is to examine how the exchange between leaders and followers affects job satisfaction and employee commitment to the organization, is there a connection between these variables and whether there are differences in the perception by managers and crew members. The study included 41 managers and 25 crew members of the river cruisers. Statistical techniques used in the paper are the descriptive statistics, correlation analysis and MANOVA. The results have shown a positive correlation between the LMX theory (the leader–member exchange theory), job satisfaction and commitment to the organization. Also, the results of the research have shown that there is no statistically significant difference between the perception of LMX exchange in the aspects of leaders and associates, but there is a difference in the perception of job satisfaction and commitment to the organization.

Study of the intrahepatic surgical margin of hilar bile duct carcinoma.

BACKGROUND/AIMS The diagnosis and treatment for hilar bile duct carcinoma has greatly improved. Frozen section is one of the modalities used to determine the intrahepatic surgical margin and the surgical approach for tumor resection. But we are sometimes faced with the case where we are perplexed whether to carry out additional surgical resection or not according to the result of frozen section, due to its inaccuracy. We studied herein the relation between the prognosis and the intrahepatic surgical margin according to the result of frozen section. METHODOLOGY We reviewed 23 cases of hilar bile duct carcinoma whose intrahepatic surgical margin was determined by frozen section and studied the cause of death and surgical procedure. Results of the frozen sections were compared with the permanent paraffin sections. RESULTS The overall survival rates at 1, 3 and 5 years after operation were 68.1, 41.3, and 33.0%, respectively. The accuracy, sensitivity and specificity of frozen section was 56.5%, 75.0%, and 46.7%, respectively. CONCLUSIONS We concluded that by evaluating the diagnosis of frozen section during the surgery it was difficult to determine intrahepatic surgical margin. Aggressive hepatic resection sometimes causes a high risk of hepatic failure in which case the histological diagnosis of the frozen section throughout should not be carried out.
Fault diagnosis using recursive least square algorithm for permanent magnet synchronous motor drives

This paper proposes a novel diagnosis scheme using parameter estimation of stator resistance, especially, in subject to the open-phase faults of PMSM drives. The stator resistances of PMSM are estimated by recursive least square (RLS) algorithm in real time. The fault diagnosis is achieved by analyzing the estimated stator resistance of each phase according to fault condition. The proposed diagnosis scheme is implemented without any extra devices. Moreover, the estimated parameter information can be used in order to improve the control performance. The feasibility of the proposed fault diagnosis scheme is proved by simulation and experimental results.
