Molecular Dynamics Simulations of Bauschinger Effects on a Defect- Free Single Crystal Nickel

In this study, the Bauschinger effect on a defectfree single crystal of Nickel is modeled implementing molecular dynamics simulations in nanoscale. The inter-atomic interactions are represented by employing embedded-atom potential. First, the stress-strain curves of tension and compression loading are simulated. The generated results show that the yield stress in compression is lower than the tensile yield stress. At the second stage, the tension-followed-bycompression process at a known strain rate is applied to the specimen. It is observed that the obtained yield stress in the reloading or reversed loading is substantially less than the compressive yield stress in the original direction which is known as Bauschinger effect. The reversed loading process is performed at different strain levels after tensile yield stress and the influence of strain levels on Bauschinger effect is studied. In this state the Bauschinger stress parameter (BP) is introduced to quantify the Bauschinger effects on Ni crystal.
ZnCl2 and vitamin C, known as antioxidants, differently potentiate the cytotoxicity of H2O2 in rat thymocytes : Cytometric analysis using forward and side scatters

The ‘antioxidant hypothesis’ proposes that antioxidant nutrients afford protection against chronic diseases by decreasing oxidative damages. The ability of zinc to retard oxidative processes has been recognized for many years. However, the application of ZnCl2 potentiates the cytotoxicity of H2O2. Thus, some antioxidants may be cytotoxic under certain oxidative conditions. Therefore, in this study, the effect of vitamin C, one of antioxidant nutrients, on the cells treated with H2O2 has been examined to see if vitamin C potentiates the cytotoxicity of H2O2. Experiments were carried out with flow cytometer and rat thymocytes. Vitamin C also potentiated the cytotoxicity of H2O2. The increase in cell lethality induced by the combination of H2O2 and ZnCl2 was associated with the increase in population of shrunken cells with increased intensity of side scatter. However, it was not the case for the combination of H2O2 and vitamin C. The profile of cytotoxicity induced by H2O2 and vitamin C was different from that by H2O2 and ZnCl2. It may be suggested that the effects of zinc and vitamin C varies from cytoprotective to cytotoxic, being dependent on the type of oxidative stress.

PHYSICAL NATURE OF TECHNICAL SYSTEMS

The article presents a systematic approach to synthesis of a conceptual technical system (TS). The starting point for creating the structure of conceptual TS are physical laws, which are required to fulfil the desired function. In order to enable connections between individual physical laws and TS structure, basic schemata (BS) are introduced. Basic schemata consist of geometrical elements and physical quantities. They represent the necessary structure for realization of the complementary physical laws. BS are applied for embodiment of the parts and they enable their assembly into complex TS. Connections between BS reveal physical nature of TS.
Seismic stratigraphy of the central South China Sea basin and implications for neotectonics

Coring/logging data and physical property measurements from International Ocean Discovery Program Expedition 349 are integrated with, and correlated to, reflection seismic data to map seismic sequence boundaries and facies of the central basin and neighboring regions of the South China Sea. First‐order sequence boundaries are interpreted, which are Oligocene/Miocene, middle Miocene/late Miocene, Miocene/Pliocene, and Pliocene/Pleistocene boundaries. A characteristic early Pleistocene strong reflector is also identified, which marks the top of extensive carbonate‐rich deposition in the southern East and Southwest Subbasins. The fossil spreading ridge and the boundary between the East and Southwest Subbasins acted as major sedimentary barriers, across which seismic facies changes sharply and cannot be easily correlated. The sharp seismic facies change along the Miocene‐Pliocene boundary indicates that a dramatic regional tectonostratigraphic event occurred at about 5 Ma, coeval with the onsets of uplift of Taiwan and accelerated subsidence and transgression in the northern margin. The depocenter or the area of the highest sedimentation rate switched from the northern East Subbasin during the Miocene to the Southwest Subbasin and the area close to the fossil ridge in the southern East Subbasin in the Pleistocene. The most active faulting and vertical uplifting now occur in the southern East Subbasin, caused most likely by the active and fastest subduction/obduction in the southern segment of the Manila Trench and the collision between the northeast Palawan and the Luzon arc. Timing of magmatic intrusions and seamounts constrained by seismic stratigraphy in the central basin varies and does not show temporal pulsing in their activities.
Multi-band speech recognition using band-dependent confidence measures of blind source separation

One of the main applications of Blind Source Separation (BSS) is to improve performance of Automatic Speech Recognition (ASR) systems. However, conventional BSS algorithm has been applied only to speech signals as a pre-processing approach. In this paper, a closely coupled framework between FDICA-based BSS algorithm and speech recognition system is proposed. In the source separation step, a confidence score of the separation accuracy for each frequency bin is first estimated. Subsequently, by employing multi-band speech recognition system, acoustic likelihood is calculated from the estimated BSS confidence scores and Mel-scale filter bank energy. Therefore, our proposed method can reduce ASR errors which caused by separation errors in BSS and permutation errors in ICA, as in the conventional approach. Experimental results showed that our proposed method improved word accuracy of ASR by approximately 10%.
The Relationship between Human Resource Information System (HRIS) Functions and Human Resource Management (HRM) Functionalities

The purpose of this paper is to discuss the relationship between Human Resource Information System (HRIS) functions and Human Resource Management (HRM) functionalities. The theoretical framework of this paper is based on previous HRM and HRIS research where the contributing role of HRIS is measured by the compliance and application level of HRIS functions to HR functionalities. A survey questionnaire was sent to five different banks and a response rate of 61.5% was received. The target groups of the questionnaire were HR departments that include HR managers and professionals in the Jordanian banking sector. In this study, human resource information system functions were found to have a relationship with HRM functionalities. More specifically, it was found that strategic integration, forecasting and planning, human resources analysis, and communication and integration have no relationship with human resource functionalities. Whereas, it was found that performance development, knowledge management, and records and compliance as dimensions of human resources information systems have a relationship with human resources functionalities. Keywords Human Resource Management, HRM functionalities, Human Resource Information System.
Power and Likelihood of Financial Statement Fraud: Evidence from Indonesia

The present study investigates whether the distribution of power between two major internal corporate governance mechanisms: Chief Executive Officer (CEO) and Board of Directors (BOD) is associated with the likelihood of financial statement fraud in Indonesian Public Listed Companies (PLCs). We employ principal component analysis on number of characteristic of power related to CEO and BOD to acquire each of three factors that characterize types of power between these key corporate governance actors. Furthermore, we extend the study by analyzing the dyadic pairing of low and high CEO and BOD power relationships and how they influence the likelihood of financial statement fraud in an emerging market country setting. The overall findings suggest when the BOD expert power increases (and to some extent when the BOD ownership power decreases), the likelihood of financial statement fraud decreases through a consistent monitoring and supervising mechanism. The findings of this study underline the need of the proactive/participatory boards in a company setting to mitigate the likelihood of financial statement fraud. This study supports the calls for maximizing the role of BOD in Indonesian companies comprehensively. 
Dynamics of a quantum spin liquid beyond integrability: The Kitaev-Heisenberg-Γ model in an augmented parton mean-field theory

We present an augmented parton mean-field theory which (i) reproduces the $exact$ ground state, spectrum, and dynamics of the quantum spin liquid phase of Kitaev's honeycomb model; and (ii) is amenable to the inclusion of integrability breaking terms, allowing a perturbation theory from a controlled starting point. Thus, we exemplarily study dynamical spin correlations of the honeycomb Kitaev quantum spin liquid within the $K-J-\Gamma$ model which includes Heisenberg and symmetric-anisotropic (pseudo-dipolar) interactions. This allows us to trace changes of the correlations in the regime of slowly moving fluxes, where the theory captures the dominant deviations when integrability is lost. These include an asymmetric shift together with a broadening of the dominant peak in the response as a function of frequency; the generation of further-neighbour correlations and their structure in real- and spin-space; and a resulting loss of an approximate rotational symmetry of the structure factor in reciprocal space. We discuss the limitations of this approach, and also view the neutron scattering experiments on the putative proximate quantum spin liquid material, $\alpha$-RuCl$_3$, in the light of the results from this extended parton theory.
Dirichlet Compound Multinomials Statistical Models

This contribution deals with a generative approach for the analysis of textual data. Instead of creating heuristic rules forthe representation of documents and word counts, we employ a distribution able to model words along texts considering different topics. In this regard, following Minka proposal (2003), we implement a Dirichlet Compound Multinomial (DCM) distribution, then we propose an extension called sbDCM that takes explicitly into account the different latent topics that compound the document. We follow two alternative approaches: on one hand the topics can be unknown, thus to be estimated on the basis of the data, on the other hand topics are determined in advance on the basis of a predefined ontological schema. The two possible approaches are assessed on the basis of real data.
Inverse modeling of GOSAT-retrieved ratios of total column CH4 and CO2 for 2009 and 2010

Abstract. This study investigates the constraint provided by greenhouse gas measurements from space on surface fluxes. Imperfect knowledge of the light path through the atmosphere, arising from scattering by clouds and aerosols, can create biases in column measurements retrieved from space. To minimize the impact of such biases, ratios of total column retrieved CH4 and CO2 (Xratio) have been used. We apply the ratio inversion method described in Pandey et al. (2015) to retrievals from the Greenhouse Gases Observing SATellite (GOSAT). The ratio inversion method uses the measured Xratio as a weak constraint on CO2 fluxes. In contrast, the more common approach of inverting proxy CH4 retrievals (Frankenberg et al., 2005) prescribes atmospheric CO2 fields and optimizes only CH4 fluxes. The TM5–4DVAR (Tracer Transport Model version 5–variational data assimilation system) inverse modeling system is used to simultaneously optimize the fluxes of CH4 and CO2 for 2009 and 2010. The results are compared to proxy inversions using model-derived CO2 mixing ratios (XCO2model) from CarbonTracker and the Monitoring Atmospheric Composition and Climate (MACC) Reanalysis CO2 product. The performance of the inverse models is evaluated using measurements from three aircraft measurement projects. Xratio and XCO2model are compared with TCCON retrievals to quantify the relative importance of errors in these components of the proxy XCH4 retrieval (XCH4proxy). We find that the retrieval errors in Xratio (mean = 0.61 %) are generally larger than the errors in XCO2model (mean = 0.24 and 0.01 % for CarbonTracker and MACC, respectively). On the annual timescale, the CH4 fluxes from the different satellite inversions are generally in agreement with each other, suggesting that errors in XCO2model do not limit the overall accuracy of the CH4 flux estimates. On the seasonal timescale, however, larger differences are found due to uncertainties in XCO2model, particularly over Australia and in the tropics. The ratio method stays closer to the a priori CH4 flux in these regions, because it is capable of simultaneously adjusting the CO2 fluxes. Over tropical South America, comparison to independent measurements shows that CO2 fields derived from the ratio method are less realistic than those used in the proxy method. However, the CH4 fluxes are more realistic, because the impact of unaccounted systematic uncertainties is more evenly distributed between CO2 and CH4. The ratio inversion estimates an enhanced CO2 release from tropical South America during the dry season of 2010, which is in accordance with the findings of Gatti et al. (2014) and Van der Laan et al. (2015). The performance of the ratio method is encouraging, because despite the added nonlinearity due to the assimilation of Xratio and the significant increase in the degree of freedom by optimizing CO2 fluxes, still consistent results are obtained with respect to other CH4 inversions.

Long‐Term Stability Studies of Anode‐Supported Microtubular Solid Oxide Fuel Cells

A long‐term stability study of an anode‐supported NiO/YSZ‐YSZ‐LSM/YSZ microtubular cell was performed, under low fuel utilization conditions, using pure humidified hydrogen as fuel at the anode side and air at the cathode side. A first galvanometric test was performed at 766 °C and 200 mA cm–2, measuring a power output at 0.5 V of ∼250 mW cm–2. During the test, some electrical contact breakdowns at the anode current collector caused sudden current shutdowns and start‐up events. In spite of this, the cell performance remains unchanged. After a period of 325 h, the cell temperature and the current density was raised to 873°C and 500 mA cm–2, and the cell power output at 0.5 V was ∼600 mW cm–2. Several partial reoxidation events due to disturbance in fuel supply occurred, but no apparent degradation was observed. On the contrary, a small increase in the cell output power of about 4%/1,000 h after 654 h under current load was obtained. The excellent cell aging behavior is discussed in connection to cell configuration. Finally, the experiment concluded when the cell suffered irreversible damage due to an accidental interruption of fuel supply, causing a full reoxidation of the anode support and cracking of the thin YSZ electrolyte.
Chemical Production Fault Detection Technology Based on Computer Process Control Software

Chemical production safety is the only way to ensure the economic benefits and development and the life safety of employees in a company. For any company, the safety production is a subject which cannot be ignored. To get early warning of the potential risks, the troubleshooting technology in the process of chemical production is no doubt vital to the modern business. For this purpose, this paper, by ways of literature investigation, comparative analysis and case analysis, and on account of chemical fault detection mechanism model, proposes a chemical production fault detection model with process simulation based on computer process control software. In the other way, the availability and the feasibility of the model also have a sound verification with simulation case analysis.
Barriers to Cross-border eCommerce in the EU Digital Single Market

This report presents empirical evidence about the internationalisation of European online firms. After describing some characteristics that define the internationalisation of firms engaged in online activities, it mainly focuses on the obstacles that these firms face when trying to sell their products and/or services to other EU Member States. It relies on data from a firm survey carried out in January-February 2015 in four different sectors (manufacturing, wholesale and retail, accommodation and food and information and communication) and is complemented with additional sources of information. We find that a limited number of barriers really matter for online trade. These include settling the costs of cross-border disputes, suppliers’ restrictions to selling cross-border, delivery costs, taxation rules, and knowledge of the rules abroad. In line with the offline trade literature, the data confirm that they matter mostly for small firms, which find it harder to overcome the fixed trade costs associated with these barriers.
Administrative Reform in International Organizations: The Case of the Joint United Nations Programme on HIV/AIDS

Cet article etudie les sources, la mise en oeuvre et les effets inattendus des reformes administratives engagees au sein du systeme des Nations Unies dans le domaine de la lutt e contre le VIH/sida. Il s’appuie sur une enquete menee au sein d’ONUSIDA, programme multi lateral reunissant dix agences onusiennes et un secretariat permanent engages dans la lutt e contre l’epidemie. Dans un premier temps, l’arti cle souligne les raisons pour lesquelles les agences multi laterales n’ont guere ete portees a impulser elles-memes des reformes, alors qu’elles etaient enjointes par le programme a mieux coordonner et harmoniser leurs reponses strategiques au sida. Ensuite, l’arti cle identi fi e trois facteurs externes ayant joue un role cle dans le lancement de la reforme des procedures et des mecanismes de gouvernance du programme ONUSIDA. Puis il explore les conditions de leur mise en oeuvre depuis 2005, en insistant tout particulierement sur le role d’« entrepreneur de reforme » joue par le secretariat d’ONUSIDA. Enfin, l’article etudie les effets induits des reformes administratives : l’importance des jeux de concurrence entre agences, le renforcement de la complexite organisati onnelle et la tendance a la bureaucratisation du systeme ONUSIDA. La conclusion defend l’idee que l’analyse de la reforme des organisations internationales implique d’etudier de facon croisee les pressions emanant de leur environnement d’une part, et les activites des entrepreneurs de reforme d’autre part.This paper focuses on the causal factors, implementation, and side effects of administrative reforms launched within the United Nations system, in the field of HIV and AIDS. It is based on an empirical analysis of the UNAIDS Programme, an interorganizational system bringing together ten UN agencies to combat the worldwide epidemic, with the support of a Secretariat. Firstly, the paper argues that the administrative reform of UNAIDS was unlikely to have come from the UN organizations themselves, although the Programme was expected to lead these organizations to better coordinate and harmonize their AIDS strategies. Secondly, it identifies three external factors that have led UN organizations to reform their governance mechanisms and procedures. Thirdly, it explores the conditions under which the reform of UNAIDS has been implemented since 2005, with particular attention to the Secretariat that has become involved as an active “reform entrepreneur. ” Finally, it identifies some of the unexpected effects of the reform, with a particular emphasis on competition between UN agencies, organizational complexity, and bureaucratization. The concluding remarks argue that when analyzing administrative reforms within international organizations, one should investigate the interrelations between the external pressures that drive reforms and the activity of reform entrepreneurs.
Impact of Enterprise Resource Planning Implementation on Supply Chain Efficiencies: A Case of Telecom Sector

Enterprise resource planning implementation (ERP) is becoming foundation to be the spine of the organization in competitive environment. The wide usage of ERP in organizations covers many aspects which include decision making, the reduction of operational cost and enhancement of the management control by automating and improving the corporate basic functions such as production, human resource, and finance and supply chain management system. This study aims to investigate the impact of ERP on the supply chain management in the context of semi government organization, where the ERP is practically implemented.
