A novel miniaturized waveguide bandpass filter using meta-material

In this paper, we proposed a novel miniaturized waveguide bandpass filter, which filled with anisotropic uniaxial meta-material with transversal negative effective permeability. The theoretical analysis is presented. A sample using the W-band standard waveguide to operate at Ka-band is simulated. From the simulation, it can be concluded that the filter has large band rejection and high selectivity. The 3-dB relative bandwidth is 3.8% at the center frequency of 34.83 GHz.

CD40L Expression Allows CD8+ T Cells to Promote Their Own Expansion and Differentiation through Dendritic Cells

CD8+ T cells play an important role in providing protective immunity against a wide range of pathogens, and a number of different factors control their activation. Although CD40L-mediated CD40 licensing of dendritic cells (DCs) by CD4+ T cells is known to be necessary for the generation of a robust CD8+ T cell response, the contribution of CD8+ T cell-expressed CD40L on DC licensing is less clear. We have previously shown that CD8+ T cells are able to induce the production of IL-12 p70 by DCs in a CD40L-dependent manner, providing some evidence that CD8+ T cell-mediated activation of DCs is possible. To better understand the role of CD40L on CD8+ T cell responses, we generated and characterized CD40L-expressing CD8+ T cells both in vitro and in vivo. We found that CD40L was expressed on 30–50% of effector CD8+ T cells when stimulated and that this expression was transient. The expression of CD40L on CD8+ T cells promoted the proliferation and differentiation of both the CD40L-expressing CD8+ T cells and the bystander effector CD8+ T cells. This process occurred via a cell-extrinsic manner and was mediated by DCs. These data demonstrate the existence of a mechanism where CD8+ T cells and DCs cooperate to maximize CD8+ T cell responses.
The Impact of Knowledge from Learning-About Electronic Health Records on IT Innovation Adoption: The Moderating Role of Absorptive Capacity

Learning-by-doing is a crucial process to successful IT adoption. Yet, this type of organizational learning process is necessary but not sufficient to the adoption success. Learning-about, the pre-adoption learning activity, plays an equally important role in an organization’s IT adoption. In healthcare industry, hospitals are not always able to utilize healthcare information technologies (HITs), such as electronic healthcare records (EHRs), to generate high quality information for decision making. Having pre-adoption knowledge and the capacity to absorb the knowledge is likely to better the adoption results. This research proposes a conceptual model to explain the importance of the knowledge from learning-about EHR technology and explore the role absorptive capacity plays in EHR pre-adoption. This study contributes to the existing EHR literature by (1) adding pre-adoption knowledge into the ingredients of successful adoption, and (2) discussing the moderating effect of absorptive capacity to the relationship between pre-adoption knowledge and outcomes of adoption.
Mutational and genotype–phenotype correlation analyses in 28 Polish patients with Cornelia de Lange syndrome

Cornelia de Lange syndrome (CdLS) is a multisystem congenital anomaly disorder characterized by prenatal and postnatal growth retardation, developmental delay, distinctive facial dysmorphism, limb malformations, and multiple organ defects. Mutations in the NIPBL gene have been discovered recently as a major etiology for this syndrome, and were detected in 27–56% of patients. Two groups have found significant differences in the severity or penetrance of some phenotypes between mutation positive and mutation negative patients. Different clinical features have also been described among patients with missense versus truncating mutations. In this study, we identified 13 NIPBL mutations in 28 unrelated Polish CdLS patients (46.4%), 11 were novel. Mutation positive patients were more severely affected in comparison to mutation negative individuals with respect to weight, height, and mean head circumference at birth, facial dysmorphism and speech impairment. Analyses of combined data from this and the two previous studies revealed that the degree of growth, developmental delay and limb defects showed significant differences between patients with and without mutations and between patients with missense and truncating mutations, whereas only a portion of these features differed significantly in any individual study. Furthermore, bioinformatic analyses of the NIPBL protein revealed several novel domains, which may give further clues about potential functions of this protein. © 2006 Wiley‐Liss, Inc.
Robustness of MIMO-OFDM schemes for future digital TV to carrier frequency offset

This paper investigates the impact of carrier frequency offset (CFO) on the performance of different MIMO-OFDM schemes with high spectral efficiency for next generation of terrestrial digital TV. We show that all studied MIMO-OFDM schemes are sensitive to CFO when it is greater than 1% of inter- carrier spacing. We show also that the Alamouti scheme is the most sensitive MIMO scheme to CFO.
Trading Probability and Turnover as Measures of Liquidity Risk: Evidence from the U.K. Stock Market

This paper utilises monthly data from the U.K. stock market to examine possible regularities in variables (trading probability and fractional turnover) which may be (or may be hypothesised to be) associated with liquidity risk. Modelling is based upon extensions to the CAPM involving variables closely similar to those employed in the Fama-French three factor model (albeit using Dividend Yield in place of the Book to Market ratio). Our findings suggest that the measure of trading probability used here is a close substitute for the market capitalisation measure associated with the 'Size' effect; and that the fractional turnover variable makes a significant contribution as an addendum to a three factor model.
Catheter-Related Bloodstream Infection Caused by Mycobacterium brumae

ABSTRACT Mycobacterium brumae is a rapidly growing environmental mycobacterial species identified in 1993; so far, no infections by this organism have been reported. Here we present a catheter-related M. brumae bloodstream infection in a 54-year-old woman with breast cancer. The patient presented with high fever (39.7°C), and >1,000 colonies of M. brumae grew from a quantitative culture of blood drawn through the catheter. A paired peripheral blood culture was negative, however, suggesting circulational control of the infection. The patient was treated empirically with meropenem and vancomycin, and the fever resolved within 24 h. The catheter was removed a week later, and from the tip M. brumae was isolated a second time, suggesting catheter colonization. The organism was identified by colonial morphology, sequence analysis of the 16S rRNA gene, and biochemical tests.
Expressed Sequence Tag Analysis of the Bradyzoite Stage of Toxoplasma gondii: Identification of Developmentally Regulated Genes

ABSTRACT Toxoplasma gondii is a protozoan parasite responsible for widespread infections in humans and animals. Two major asexual forms are produced during the life cycle of this parasite: the rapidly dividing tachyzoite and the more slowly dividing, encysted bradyzoite. To further study the differentiation between these two forms, we have generated a large number of expressed sequence tags (ESTs) from both asexual stages. Previously, we obtained data on ∼7,400 ESTs from tachyzoites (J. Ajioka et al., Genome Res. 8:18–28, 1998). Here, we report the results from analysis of ∼2,500 ESTs from bradyzoites purified from the cysts of infected mice. We also report the results from analysis of 760 ESTs from parasites induced to differentiate from tachyzoites to bradyzoites in vitro. Comparison of the data sets from bradyzoites and tachyzoites reveals many previously uncharacterized sequence clusters which are largely or completely specific to one or other developmental stage. This class includes a bradyzoite-specific form of enolase. Combined with the previously identified bradyzoite-specific form of lactate dehydrogenase, this finding suggests significant differences in flux through the lower end of the glycolytic pathway in this stage. Thus, the generation of this data set provides valuable insights into the metabolism and growth of the parasite in the encysted form and represents a substantial body of information for further study of development in Toxoplasma.
The determinants of the profitability of Malaysian public listed companies

This study explores the determinants of public listed companies’ profitability in Malaysia during the financial crisis period in 2008. Return on assets (ROA) is used as a measurement for company profitability while for independent variables, the company specifics determinants (internal factor) and macroeconomic determinant (external factor) are used to determine the company profitability. The company specific determinants are size, liquidity, leverage, and sales growth while for macroeconomic determinant, gross domestic product (GDP) is used. This study utilizes a sample of 161 companies listed in Bursa Malaysia for over the period 2001-2012. All sectors are included in this sample except financial sector because their nature of reporting business is different from the ordinary sectors. The data are analyzed using Ordinary Least Squares (OLS) and fixed effects estimation. The findings show that leverage has a negative and significant relationship with the ROA, implying that companies that have low debt ratio will have higher profit. On the other hand, size, liquidity, and sales growth have a positive and significant relationship with the ROA, indicating that, bigger size companies, highly liquid companies, and companies that able to generate higher sales will have more profits. As for macroeconomic determinant GDP and 2008 dummy are not significant, indicating that the profitability of Malaysian public listed companies is not affected by the economic condition and 2008 global financial crisis.
The relationship between strategic orientation and firm performance : evidence from small and medium enterprises in Malaysia

Recent research in business and marketing has highlighted the importance of the concept of strategic orientation or ‘strategic directions implemented by a firm to create proper behaviours for the continuous superior performance of a business (Gatingnon and Xuereb 1997, p.78). This study seeks to determine if strategic orientation can help improve firm performance of Malaysian SMEs. Although, many types of strategic orientations have been discussed in the literature, this study chose three most comprehensive constructs that encompass significant actions targeting main areas in the operation of any business. These include; entrepreneurial orientation relating to the proactive leadership skills of the entrepreneur, market orientation directed to winning over and retaining customers with best marketing practices and interaction orientation focussed on customer relationship and management. This study applied quantitative method and used Structural Equation Modelling (SEM). As there has been some criticism that direct correlation of one particular strategic orientation to firm performance is prone to simplification, this study adopts a combination of these strategic orientations to present a holistic picture of the effect of strategic orientation on firm performance. This study also employs innovation success as mediating variable of the strategic orientation/ firm performance to present a more nuanced picture of this relationship by arguing that strategic orientation is able to deliver superior firm performance directly or indirectly by affecting innovation success. In addition, market turbulence (instability of customer preference) and competitive intensity (presence of aggressive competitors) are employed as antecedent variables on strategic orientation to reflect factors of external environment that can intervene in the actions of a firm.
Transmission of Schmallenberg virus in a housed dairy herd in the UK

Peste des petits ruminants (PPR), caused by the PPR virus (PPRV), a Morbillivirus from the family Paramyxoviridae , is a well-recognised disease of small ruminants (Gibbs and others 1979) of exceptional importance in affected countries (OIE 2012). It also affects many species of wild small ruminants (Gur and Albayrak 2010), and was found to cause significant losses in captive wild hoofstock throughout the United Arab Emirates (UAE) in 2005/2006 and 2008/2009 (Kinne and others 2010). Such outbreaks might represent a significant extinction threat to valuable populations in the area. Because culling is not desirable, prophylactic approaches to disease protection, such as effective vaccination programmes are to be favoured. Although a live attenuated vaccine has been shown to be protective in domestic small ruminants, (Diallo and others 1989), there are no documented reports of PPRV vaccine trials in exotic hoofstock. The purpose of this study was to investigate and document seroconversion in one species of wild ungulate, the Arabian oryx ( Oryx ­leucoryx ) in response to inoculation with a commercially available PPRV vaccine. Fifteen healthy (based on physical exam and haematology) Arabian oryx from a private wildlife collection in Dubai, UAE (8 males; 7 females; 11–32 months old), were used in this study. For sampling, animals were restrained using a runway-drop chute system (Tamer; Fauna Research, USA) as described by O'Donovan and Bailey …
Investor Behavior and Volatility Asymmetry

The paper analyses the tendency of investors to realize gains too early and the reluctance to liquidate losing positions. Analysis is based on the complete transaction data of the Estonian stock market. The Cox proportional hazard model along with ratio analysis is used to measure the disposition effect. I find presence of the disposition effect on the market but contrary to other investor groups, foreign investors seem to exhibit a "reverse disposition effect" that can be caused by different behavioral characteristics compared to local investors, especially risk aversion. Foreign investors are more driven by momentum strategies whereas local investors pursue the contrarian approach. Experience and investor sophistication seem to decrease the disposition effect.

Dilemmas of Equity Cost Calculation in Polish Mining Enterprises

The purpose of the paper is to present the methods of equity capital cost calculation and the attempt is made to implement them in the conditions of unstable environment of the Polish mining enterprises’ performance. In the theory of finance, there are many methods of equity cost calculation functioning, however, there are also many controversies and difficulties attached. The author conducts the analysis of possibility to use the following methods in estimating the cost of capital: CAPM (Capital Asset Pricing Model), APM (Arbitrage Pricing Model), DGM (Dividend Growth Model), DCF (Discounted Cash Flow), three-factor pricing model (Fama-French Model), BPM (Butler-Pinkerton Model), and Build-up Approach. The implementation of the common concepts of equity cost calculation in specificity of mining enterprises is a new approach in finance management of mining enterprises. The research results shall find their use in the effectiveness account and value pricing of mining enterprises, planning capital structure and other circumstances of mining activity. Introducing some known methods of equity cost calculations is not always possible on the grounds of mining enterprises. The research results constitute an extension in finance theory of mining enterprises regarding problems of adjusting equity cost calculation methods to the specific conditions in which mining enterprises perform.
Round-the-Clock Trading: Evidence from U.K. Cross-Listed Securities

This paper uses transactions data from the London Stock Exchange to characterize the intraday pattern of security prices and trading volume for securities trading on SEAQ. It focuses in more detail on a sample of U.K. firms that are cross-listed on the NYSE. Using additional data from the NYSE-AMEX (I5SM), we compare volatility, volume, and quotes as trading starts in London and then continues in New York. These firms have substantially longer trading hours than most singly-listed stocks, and are also traded in two markets with very different institutional setups. This is shown to have several important implications for theories on intraday behavior of prices, the organization of exchanges, and the general consequences of round-the-clock trading.
Protein subunit interfaces: heterodimers versus homodimers

Protein dimers are either homodimers (complexation of identical monomers) or heterodimers (complexation of non-identical monomers). These dimers are common in catalysis and regulation. However, the molecular principles of protein dimer interactions are difficult to understand mainly due to the geometrical and chemical characteristics of proteins. Nonetheless, the principles of protein dimer interactions are often studied using a dataset of 3D structural complexes determined by X-ray crystallography. A number of physical and chemical properties govern protein dimer interactions. Yet, a handful of such properties are known to dominate protein dimer interfaces. Here, we discuss the differences between homodimer and heterodimer interfaces using a selected set of interface properties.
ITERATIVE LEARNING CONTROL FOR NON-UNIFORM TRAJECTORY TRACKING PROBLEMS

Abstract In this work Iterative Learning Control is extended to non-uniform trajectory tracking problems for certain classes of nonlinear uncertain systems. The proposed ILC scheme can learn from different motion patterns and guarantee the asymptotic convergence even if the target trajectory varies at every iteration. The concept of Composite Energy Function (CEF) is adopted to facilitate the convergence property analysis, which shows that the uniform convergence of the tracking error is achieved.

Nutritional requirements of fish

The impetus for accurate information on the nutrient requirements of fish derives very largely from the development, in many parts of the world, of an aquaculture industry that is dependent on artificial feeds. At the same time such information can provide the basis for comparative nutrition, whereby features of the nutrition of cold-blooded, water-breathing and mainly, carnivorous vertebrates which differ from the pattern largely common to omnivorous mammals are identified. Since this topic was last addressed (Cowey, 1988) the aquaculture industry has continued to grow, fuelled both by the continuing overexploitation of the marine environment, resulting in declining yields, and by the high quality of aquaculture products. The first serious studies on nutritional requirements of fish were made in the 1950s. Since then much has been learned concerning fish husbandry, water quality, pellet quality (water stability) of fish diets and so on. Consequently, general methodological standards in nutritional experiments have improved greatly and some of the early values for nutrient requirements need to be revised, usually downward.
A nonlinear attitude control law for a satellite with flexible appendages

The paper deals with the wide angle attitude control problem for a satellite with flexible appendages. On the basis of the model specified by the kinematic equations, in the unitary quaternions parametrization, and by the dynamical equations, which result from the hybrid coordinates approach, it is proposed a static state feedback control law for the problem under study. The similations implemented are characterized by the effort of overcoming some obvious problems which arise in the practical implementation of the proposed control law.
