A non-linear high order explicit differential transform based method for solving initial value problems

In this paper, a reliable non-linear high order explicit differential transform based method for solving initial value problems of ODEs is presented. The method is based on deriving a general nonlinear relation between the dependent variable and its derivatives from the well known differential transform method. The method results in rational explicit one step integration schemes with arbitrary-order accuracy. The error and stability analysis of the method is presented. Some stiff and nonstiff initial value problems are solved to illustrate the performance and accuracy of the method. 1112 E. R. El-Zahar et al. Mathematics Subject Classification: 65L05, 65L20
Effect of creatine addition in feeds containing animal meals on the performance and carcass yield of broilers

The objective of this study was to evaluate the performance and carcass characteristics of broilers fed exclusively vegetable diets and diets containing animal meal with the addition of creatine or not after day 8. In the experiment, 1080 one-day-old male chicks were distributed according to a completely randomized experimental design into six treatments with six replicates each. A control diet based on corn and soybean meal was formulated, to which animal meals and creatine were included or not. Diets were formulated to contain equal mineral (calcium, phosphorus and sodium) and amino acid (available methionine + cystine, lysine and threonine) levels. The following treatments were applied: A. control (diet based on corn and soybean meal); B. control + creatine (600g/ton); C. inclusion of 5% meat and bone meal (MBM), D. inclusion of 5% MBM + creatine (600g/ton), E. inclusion of 5% blood meal (BM), F. inclusion 5% BM + creatine (600g/ton). Weight gain, feed intake, feed conversion, carcass yield and viability were evaluated. At 42 days of age, BM dietary inclusion impaired weight gain and feed conversion ratio. The inclusion of MBM affected only feed conversion ratio. The addition of creatine ito the diet with BM improved weight gain when compared with the BM diet with no creatine. The addition of creatine to the diet containing 5% BM improved weight gain when compared with the same diet without the use of the additive.
New Service Development Process in Intermodal Transport: The Case of Turkey*

Increasing interest on intermodal transport both by the shippers and carriers has led logistics service providers and transport operators to develop new intermodal transport services. When the service literature is analyzed, it is found that there are a few studies on the New Service Development (NSD) of specific service industries. However, it is observed that there is a gap in new intermodal service development. That’s why this study aims to explore the stages and determine the common stages in NSD process of intermodal transport. In order to reach this aim, intermodal transport operators and service providers offering intermodal transport services in Turkey are investigated by case study method. This study is the preliminary step for NSD processes in intermodal transport for the current literature. According to the findings, the issues of the human resources have not been paid enough attention during the NSD process. It is concluded that intermodal transport requires more detailed and industry-specific NSD models compared with the other service industries.
An H I absorbing circumnuclear disk in Cygnus A

We present Very Long Baseline Array (VLBA) HI absorption observations of the core region of the powerful radio galaxy Cygnus A. These data show both broad (FWHM = 231 +/- 21 km s(-1)) and narrow (FWHM 10(4) cm(-3) and total column density in the range 10(23)-10(24) cm(-2). Models in which the Hi absorption is primarily from an atomic or a molecular gas phase can both fit our data. Modelling taking into account the effective beam shows that the broad Hi absorbing gas component does not cover the radio core in Cygnus A and therefore does not contribute to the gas column that blocks our view of the hidden quasar nucleus. If however Cygnus A were observed from a different direction, disk gas on similar to 100 pc radius scales would contribute significantly to the nuclear column density, implying that in some radio galaxies gas on these scales may contribute to the obscuration of the central engine. We argue that the circumnuclear torus in Cygnus A contains too little mass to power the AGN over > 10(7) yr but that material in the outer Hi absorbing gas disk can provide a reservoir to fuel the AGN and replenish torus clouds. The second narrow Hi absorption component is significantly redshifted (by 186 km s(-1))with respect to the systemic velocity and probably traces infalling gas which will ultimately fuel the source. This component could arise either within a tidal tail structure associated with a recent (minor) merger or be associated with an observed infalling giant molecular cloud.
What do You Expect? A Reconfiguration of the Audit Expectations Gap

This paper undertakes a conceptual enquiry into the idea of the expectations gap. This method of enquiry is explained as a philosophical investigation into the concepts used in the literature relating to the expectations gap. A descriptive conceptual enquiry is undertaken into the current use of the expression ‘expectations gap’ and the related terms ‘expectation’ and ‘expects’. It is argued that vagueness and misunderstandings of the uses of these expressions undermines a grasp of the issues involved and of how they are to be resolved. The paper looks at the various explanations of these expressions in the literature and suggests that more clarity in discussions of the issues would be achieved by characterizing expectations as beliefs about what auditors do or desires for them to perform certain procedures with certain qualities in audits. The grounds for the beliefs are considered. The belief that the auditor will do something because of a belief that it is a duty is examined. The way in which the auditor's beliefs that something is a duty determines what they do is explained through the idea of practical reasoning. The paper goes on to explore the suggestion that an expectation might also be some kind of desire that auditors perform certain actions in the context of an audit. These desires are related to a consideration of the objectives of auditing. The idea of the reasonableness of these desires is examined. The reasons for wanting auditors to undertake particular procedures can also underlie the acceptance of particular meanings of ‘audit’ and ‘auditing’. The audit expectations gap is reconfigured in terms of the beliefs and desires identified in the paper.
Decentralized Control Strategy for Optimal Energy Management in Grid-Connected and Islanded DC Microgrids

This paper proposes a decentralized control technique to minimize the total operation cost of a DC microgrid in both grid-connected and islanded modes. In this study, a cost-based droop control scheme based on the hourly bids of all participant distributed generators (DGs) and the hourly energy price of the utility is presented. An economic power sharing technique among various types of DG units is adopted to appropriately minimize the daily total operation cost of DC microgrid without a microgrid central controller. The DC microgrid may include non-dispatchable DG units (such as photovoltaic systems) and dispatchable generation units. Unlike other energy management techniques, the proposed method suffers neither from forecasting errors for both load demand and renewable energy power prediction modules, nor from complicated optimization techniques. In the proposed method, all DGs and the utility are classified in a sorting rule based on their hourly bids and open market price, and then the droop parameters are determined. The simulation results are presented to verify the effectiveness of the proposed method using MATLAB/SIMULINK software. The results show that the proposed strategy is able to be implemented in various operation conditions of DC microgrid with resistance to uncertainties.
Effect of Visual Biofeedback Training in Real Time on Buttock Pressure and Pelvic Tilting Angles of Hemiplegic Patients During Sitting

1) Background: After a stroke, the control of the trunk muscle may be severely impaired. Due to the importance of trunk control in complex daily postures, the ability to adopt a correct sitting posture is considered a determinant of the recovery of independent function after a stroke. Objects: The purposes of this study were to compare differences in buttock pressure between the left and right sides of hemiplegic patients and differences in their pelvic tilting angles (sagittal and coronal planes) after sitting training with visual biofeedback (VBF) in real time. Methods: Twenty-two individuals with unilateral strokes (11 left-side and 11 right-side hemiplegic stroke patients) participated in this study. Buttock pressure was measured using a pressure mat, and pelvic angles were measured using a palpation meter. Results: The asymmetry of pressure between the right and left (first and third chamber) sides was significantly decreased after the VBF training. The measurements obtained using the palpation meter revealed a significant decrease in the pelvic angles preversus post-intervention. Conclusion: VBF training may be distribute a patient’s buttock pressure equally while in a sitting posture and increase the length of time a stroke patient can maintain a symmetrical sitting posture. It can also improve pelvic control while sitting in a neutral position.
Terahertz Signal Generation in 1-D Photonic Crystals

En este trabajo presentamos resultados teoricos y numericos que aseguran poder obtener una fuente de radiacion coherente, sintonizable y de banda angosta en la region terahertz del espectro electromagnetico. Nuestra propuesta se basa en e1 efecto de conversion parametrica no lineal y en el mecanismo de amplificacion del campo. Estos efectos se obtienen simultaneamente al sintonizar dos fuentes laser en la orilla de la banda prohibida o en el modo de un defecto localizado del cristal fotonico. La frecuencia de la senal obtenida puede ser sintonizada al mezclar las dos fuentes laser con diferente angulo de incidencia. Las polarizaciones son degeneradas a un angulo de incidencia normal y la conversion parametrica genera senales sub-terahertz. Para una muestra especifica, mostramos que cambiando el angulo de incidencia de un laser sincronizable a 30 grados, la frecuencia de la senal obtenida en el cristal es de 11.5 THz para la polarizacion p y de 3.5 THz para la polarizacion s. Esto es debido a que el espectro de transmision es dependiente del angulo y por lo tanto, existen diferencias para la polarizacion p y para la s. La eficiencia de conversion pico para ambas polarizaciones es amplificada por mas de dos ordenes de magnitud. Finalmente, tambien se muestran algunos resultados experimentales preliminares que concuerdan con los resultados numericos que presentamos en este articulo.
Toward the excited meson spectrum of dynamical QCD

We present a detailed description of the extraction of the highly excited isovector meson spectrum on dynamical anisotropic lattices using a new quark-field construction algorithm and a large variational basis of operators. With careful operator construction, the combination of these techniques is used to identify the continuum spin of extracted states reliably, overcoming the reduced rotational symmetry of the cubic lattice. Excited states, states with exotic quantum numbers (0+-, 1-+ and 2+-) and states of high spin are resolved, including, for the first time in a lattice QCD calculation, spin-four states. The determinations of the spectrum of isovector mesons and kaons are performed on dynamical lattices with two volumes and with pion masses down to ~ 400 MeV, with statistical precision typically at or below 1% even for highly excited states.
Corporate liquidity and profitability of listed food and beverages firms in Nigeria

The management of corporate liquidity plays a pivotal role in maintaining the financial health of the company during the normal course of business. The objective of this study is to examine the effect of corporate liquidity and profitability of listed Food and Beverages Firms in Nigeria. The study covers the period of six years 2009 to 2014. Data for the study were extracted from the firms’ annual reports and accounts. After running the OLS regression, a robustness test was conducted for validity of statistical inferences, the data was empirically tested between the dependent and the independent variables. A multiple regression was employed to test the model of the study using Robust OLS. The results from the analysis revealed a strong positive relationship between quick ratio, accounts payable, IFRS, firm size and ROA of Listed Food and Beverages Firms in Nigeria, while accounts receivable was found to be inversely significantly related to ROA of Listed Food and Beverages Firms in Nigeria. Cash conversion cycle was inversely but statistically not significantly related to ROA. In line with the above findings, the study recommended that the management of listed Food and Beverages Firms in Nigeria should maintain a higher quick ratio as it will have a positive impact on their profitability and that it has empirically proved that higher quick ratio signifies more profitability, they should also try to reduce their collection period because shorter collection period increases their profitability. Finally, the management should also delay their short term obligations as it was found that more profitable firms do wait a little longer to pay their bills. Keyword: Quick ratio, accounts receivable, accounts payable, cash conversion cycle, IFRS, firm size, return
Framing Politics at the Launch of the Euro: A Cross-National Comparative Study of Frames in the News

This study of the main evening television news programs in four European countries focuses on the framing of news surrounding a major European event, the January 1, 1999, introduction of the common European currency, the euro. We investigated the visibility of political and economic news in general and of the launch of the euro in particular. We found variations across countries in the emphasis on political and economic news, with the proportion of the newscast normally devoted to these subjects ranging from 45% to 60%. Journalists in all countries were more likely to emphasize conflict (rather than economic consequences) in framing general political and economic news. In the coverage of the launch of the euro, there was a greater emphasis on framing the news in terms of economic consequences. The findings are discussed in terms of influences on framing practices internal and external to journalism and the value of the cross-national comparative approach.
Road Traffic Congestion Management Based on a Search-Allocation Approach

Abstract This paper introduces a new scheme for road traffic management in smart cities, aimed at reducing road traffic congestion. The scheme is based on a combination of searching, updating, and allocation techniques (SUA). An SUA approach is proposed to reduce the processing time for forecasting the conditions of all road sections in real-time, which is typically considerable and complex. It searches for the shortest route based on historical observations, then computes travel time forecasts based on vehicular location in real-time. Using updated information, which includes travel time forecasts and accident forecasts, the vehicle is allocated the appropriate section. The novelty of the SUA scheme lies in its updating of vehicles in every time to reduce traffic congestion. Furthermore, the SUA approach supports autonomy and management by self-regulation, which recommends its use in smart cities that support internet of things (IoT) technologies.
Promoting HIV Testing Through Non-Governmental Organizations in China: Complementary to the Government Programs

Human immunodeficiency virus (HIV) voluntary counseling and test (VCT) is an intervention that includes both voluntary preand post-test counseling and HIV testing. Its essence is that people, of their own free will, opt for VCT, and it provides them with an opportunity to confidentially explore and understand their HIV risks as well as to learn their HIV status. The purpose of VCT is to improve access to prevention, care and treatment services through early detection of HIV [1]. Early detection, timely linkage to care, and prompt initiation of antiretroviral therapy (ART) also have additional benefits in reducing HIV transmission as well as morbidity and mortality [2,3]. VCT in many countries is provided by non-governmental organizations (NGOs).
Instantaneous power variance and radio frequency to dc conversion efficiency of wireless power transfer systems

This study compares the maximum rectifier radio frequency (RF)–dc conversion efficiency for various input signals with random modulation. The instantaneous power variance (IPV) is proposed as an easy to compute parameter to classify the effect of modulation on the obtained rectifier efficiency. A prototype ultra high frequency (UHF) rectifier is used to simulate as well as measure the performance of randomly modulated signals with binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), 8 phase-shift keying (PSK) and 64 quadrature amplitude modulation (QAM) modulations. In addition to considering different modulation formats, the roll-off factor of the baseband filter is also varied due to the fact that it has a strong impact on the time-varying nature of the signal envelope. For the given rectifier, it is shown that the peak RF–dc conversion efficiency versus the output load is shifted to larger load values for signals with higher IPV. Furthermore, by comparing signals with different time-varying envelope characteristics, it is shown that IPV represents a more accurate signal characteristic than peak-to-average power ratio in terms of properly characterising the effect of modulation on the rectifier efficiency.
Organotropic Kinetics in Acute Sublethal Transient Cytomegalovirus Infection in Mice

We determined the primary level of dissemination of the cytomegalovirus into the mouse organs and its significance. This was completed before we engaged in a wider project on the immune and molecular aspects of the pathogenesis of MCMV infection in the Balb/c mice. By this venture, we may have opened opportunities to develop one or more vaccines against the virus. Mice were inoculated intraperitoneally with the virus. At day 1, 3, 7, 14 and 28 after infection, the murine organs including the spleen, salivary glands, inguinal lymph nodes, liver, bone marrow, and lungs, were collected. The organs were assessed for the expression of MCMV-DNA, for the infectious viral titer and part of the tissues was formalin-fixed and paraffin-embedded for morphological evaluation. Each organ was found to present a different configuration of the three components reflecting the viral spread. Thus, the lungs and the bone marrow showed high levels of DNA and low titers of infectious virus, taken to mean evidence of latency. The salivary glands revealed evidence of a persistent infection, as expressed by high levels of MCMV-DNA and constant titers of infective virus that lasted beyond day 28. However, the most remarkable finding was that the latency probably discerned in the spleen was localized in the stromal cells, but not in the lymphocytic component. To this extent, we may have determined the MCMV journey in the mouse.
Kaspar Hauser - Perceiving the unfamiliar human

In the history of curative education, the figure of Kaspar Hauser is given much prominence in both philosophical anthropology and psychology. The observations made about him offered plentiful food for thought as to the conditions of language acquisition as well as the social and cognitive development of the child. From his first arrival in Nuremberg on Whitsunday of 1828, Kaspar Hauser’s enigmatic fate famously attracted an unusual degree of public attention, and still does to this day. Many artists made him their subject matter, both in fact and in fiction, through poetry, novel, drama and film. He is portrayed as the epitome of man, or rather of a particular human condition: In many ways, he is the abandoned stranger with no knowledge of his past or control of his own destiny. For Karl König, curative pedagogue and founder of the Camphill movement, Kaspar Hauser, Victor von Aveyron and others stood at the very beginning of curative education, representing the fate of children who are, for a multitude of reasons, prevented from developing their individuality and participating in social life.1
The evolution of the scalar curvature of a surface to a prescribed function

We investigate the gradient flow associated to the prescribed scalar curvature problem on compact Riemannian surfaces. We prove the global existence and the convergence at infinity of this flow under sufficient conditions on the prescribed function, which we suppose just continuous. In particular, this gives a uniform approach to solve the prescribed scalar curvature problem for general compact surfaces.
Investigation of intrinsic dynamics of enzymes involved in metabolic pathways using coarse-grained normal mode analysis

Abstract Intrinsic dynamics of proteins are known to play important roles in their function. In particular, collective dynamics of a protein, which are defined by the protein’s overall architecture, are important in promoting the active site conformation that favors substrate binding and effective catalysis. The primary sequence of a protein, which determines its three-dimensional structure, encodes unique dynamics. The intrinsic dynamics of a protein actually link protein structure to its function. In the present study, coarse-grained normal mode analysis was performed to examine the intrinsic dynamic patterns of 24 different enzymes involved in primary metabolic pathways. We observed that each metabolic enzyme exhibits unique patterns of motions, which are conserved across multiple species and functionally relevant. Dynamic cross-correlation matrices (DCCMs) are visibly identical for a given enzyme family but significantly different from DCCMs of other protein families, reinforcing that proteins with similar function exhibit a similar pattern of motions. The present work also reasserted that correct identification of unknown proteins is possible based on their intrinsic mobility patterns.
