Performance analysis of optical burst switched node with deflection routing

As the optical network evolves from static long haul connection provider to an adaptive and "smart" backbone solution, optical burst switching (OBS) becomes an attractive scheme for its flexibility and efficiency. However, how to reduce data loss is a crucial issue in such an asynchronous and one-way reservation system. In this paper, we study one contention resolution strategy in OBS networks: deflection routing. We extend an existing work to provide approximate and accurate models for the data loss analysis of single OBS node with and without wavelength conversion capability. The accuracy of our models is evaluated by simulation results.
Double-focusing mixing jet for XFEL study of chemical kinetics

A novel method for time-resolved study of chemical kinetics using a windowless mixing jet at an X-ray free-electron laser (XFEL) is described and demonstrated. The short mixing time gives a time resolution of about 250 µs; the design introduces controllable delays after the initiation of a chemical reaction, allowing the possibility for detection of transient structures by an XFEL beam pulse. Applications may include time-resolved enzyme–substrate imaging or protein folding.
Delivering of Proteins to the Plant Vacuole—An Update

Trafficking of soluble cargo to the vacuole is far from being a closed issue as it can occur by different routes and involve different intermediates. The textbook view of proteins being sorted at the post-Golgi level to the lytic vacuole via the pre-vacuole or to the protein storage vacuole mediated by dense vesicles is now challenged as novel routes are being disclosed and vacuoles with intermediate characteristics described. The identification of Vacuolar Sorting Determinants is a key signature to understand protein trafficking to the vacuole. Despite the long established vacuolar signals, some others have been described in the last few years, with different properties that can be specific for some cells or some types of vacuoles. There are also reports of proteins having two different vacuolar signals and their significance is questionable: a way to increase the efficiency of the sorting or different sorting depending on the protein roles in a specific context? Along came the idea of differential vacuolar sorting, suggesting a possible specialization of the trafficking pathways according to the type of cell and specific needs. In this review, we show the recent advances in the field and focus on different aspects of protein trafficking to the vacuoles.
Two-Dimensionalism and Natural Kind Terms

Kripke and Putnam have convinced most philosophers that we cannot do metaphysics of nature by analysing the senses of natural kind terms – simply because natural kind terms do not have senses. Neo-descriptivists, especially Frank Jackson and David Chalmers, believe that this view is mistaken. Merging classical descriptivism with a Kaplan-style two-dimensional framework, neo-descriptivists devise a semantics for natural kind terms that assigns natural kind terms socalled ‘primary intensions’. Since primary intensions are senses by other names, Jackson and Chalmers conclude that we can and should do metaphysics of nature by analysing the natural kind concepts competent speakers possess. I argue that neo-descriptivism does not provide a suitable basis for doing this kind of metaphysics. I first of all give a detailed account of the neodescriptivist semantics and deflate the intuitive support neo-descriptivists try to draw from their case of the XYZ-world. I then present three arguments – the Argument from Ignorance, the Argument from Conceptual Analysis, and the Argument from Occasion Terms. Taken together, these arguments undermine the neo-descriptivist analysis of natural kind terms. I conclude that natural kind terms do not have senses, that we cannot do metaphysics of nature by analysing the senses of our kind terms, and that the Kripke-Putnam account still provides the best semantics for natural kind terms we have.
Influence of heme oxygenase-1 expression on immune liver fibrosis induced by cobalt protoporphyrin in rats.

AIM To investigate the effect of heme oxygenase-1 (HO-1) expression on immune liver fibrosis induced by cobalt protoporphyrin (CoPP) in rats. METHODS An immune liver fibrosis model of rat was established by administering human serum albumin (HSA). The rats were divided into CoPP, liver fibrosis and normal control groups. Rats in the CoPP group received intraperitoneal CoPP concurrently with HSA. Expression of HO-1 protein was observed by Western blotting and immunohistochemistry. Hematoxylin and eosin (HE) staining was performed to assess fibrosis proliferation and distribution, proliferation extent of fibroblasts, and alterations in hepatocytes and inflammatory cells. Type I and III collagens were detected with Van Gieson's (VG) staining and Foot's reticular fiber staining, respectively. In addition, spindle-shaped cells existing at perisinusoidal locations beyond portal and septa areas were investigated with HE staining. RESULTS Western blotting and immunohistochemistry showed that the expression of HO-1 protein was higher in the CoPP group than in the liver fibrosis group (P < 0.05). Compared with the liver fibrosis group, the serological index of hepatic fibrosis in the CoPP group decreased significantly (P < 0.05). HE, VG and Foot's staining revealed that administration of CoPP reduced the extent of hepatic fibrosis. The levels of serological indicators and the number of spindle-shaped cells at perisinuous locations beyond the portal and septa areas were reduced in the CoPP group. Only a few inflammatory cells were seen around the portal areas and central veins in the CoPP group. CONCLUSION Increased endogenous HO-1 may suppress liver fibrosis by protecting liver cells, inhibiting inflammatory cell infiltration and hepatic stellate cell transformation.
Red Fluorescent Protein Responsible for Pigmentation in Trematode-Infected Porites compressa Tissues

Abstract. Reports of coral disease have increased dramatically over the last decade; however, the biological mechanisms that corals utilize to limit infection and resist disease remain poorly understood. Compromised coral tissues often display non-normal pigmentation that potentially represents an inflammation-like response, although these pigments remain uncharacterized. Using spectral emission analysis and cryo-histological and electrophoretic techniques, we investigated the pink pigmentation associated with trematodiasis, infection with Podocotyloides stenometre larval trematode, in Porites compressa. Spectral emission analysis reveals that macroscopic areas of pink pigmentation fluoresce under blue light excitation (450 nm) and produce a broad emission peak at 590 nm (±6) with a 60-nm full width at half maximum. Electrophoretic protein separation of pigmented tissue extract confirms the red fluorescence to be a protein rather than a low-molecular-weight compound. Histological sections demonstrate green fluorescence in healthy coral tissue and red fluorescence in the trematodiasis-compromised tissue. The red fluorescent protein (FP) is limited to the epidermis, is not associated with cells or granules, and appears unstructured. These data collectively suggest that the red FP is produced and localized in tissue infected by larval trematodes and plays a role in the immune response in corals.
Culture As a Successor of Quality Initiatives: A Review

Quality management has been extensively used for few decades now. Organisations worldwide have leveraged the concept of quality to achieve their goals and survive the tides of competition. Organisational culture represents a collective belief and values of the organisation's members. Literatures relating to quality initiatives and organisational culture have repeatedly described that organisational culture study is imperative to implementation of quality initiatives. Now, with an aim to digress the focus from culture as a predecessor to quality initiatives, attempt has been made to find out the scope of research of impact of various quality initiatives on organisational culture as the organisation evolves. It would be of much interest to the young managers to understand the implications of process improvements on the organisational culture. Changes in processes may bring changes in the values, beliefs, attitudes of the individuals engaged in process improvements. The culture, thus created will instil a confidence to take up any change activity for organisational development and facilitate in surviving the stress and strains of any unpredictable environment.
Lexical and Syntactic cues to identify Reference Scope of Citance

In this paper, we present our system addressing Task 1 of CL-SciSumm Shared Task at BIRNDL 2016. Our system makes use of lexical and syntactic dependency cues, and applies rule-based approach to extract text spans in the Reference Paper that accurately reflect the citances. Further, we make use of lexical cues to identify discourse facets of the paper to which cited text belongs. The lexical and syntactic cues are obtained on pre-processed text of the ci-tances, and the reference paper. We report our results obtained for development set using our system for identifying reference scope of citances in this paper.
De la Homofilia a la cohesión social y viceversa

This article has four articulated objectives. First, presenting the contents with which, in the ad hoc literature, Social Cohesion and Homofily are indentified and analysed. Both concepts steam from different traditions which have originated dissimilar definitions. Second, to find an anchorage among both conceptions that permits a conjugation in their identification and processing: it is a matter of the relations-interactions among individuals or other agents. Third, developing an open conception of both contents, Social Cohesion and Homofily, as a social process of mutual feedback. At last, in fourth place, the article presents a possibility of convergence as a process of method and calculation to study the conjugation between Social Cohesion and Homofily inside a more extensive process of feedback among both.
A Semantic Theory for Global Computing Systems

We introduce cKlaim, a process calculus that can be thought of as a variant of the π-calculus with process distribution, process mobility and asynchronous communication through distributed repositories. Upon it, we develop a semantic theory to reason about programs. More precisely, we introduce a natural contextually defined behavioural semantics, give a coinductive characterization in terms of a labelled bisimulation and illustrate some significant laws. Then, we smoothly tune the theory to model two more concrete settings obtained by explicitly considering failures and node connections, two low-level features that in real life can affect the underlying network infrastructure and, hence, the ability of processes to perform remote operations.

Multi-band MIMO antenna for wireless devices

A compact printed triple band multiple-input-multiple-output (MIMO)/diversity antenna is proposed. The antenna consists of two elements with a size of 39×40 mm2 operating at 1.9 GHz, 2.4 GHz, and 5-6 GHz. The proposed antenna is suitable for IEEE801.11n and PCS applications. The characteristics of the proposed antenna such as reflection coefficient, gain, and mutual coupling between the elements have been investigated to verify the functionality of the antenna system.
Combined Spinal-Epidural Anesthesia for Cesarean Delivery: Dose-Dependent Effects of Hyperbaric Bupivacaine on Maternal Hemodynamics

Hypotension remains an important side effect of spinal anesthesia for cesarean delivery. There is limited evidence that reducing the spinal dose has a favorable effect on maternal hemodynamic stability. We designed the present randomized trial to test the hypothesis that reducing the spinal dose of local anesthetics results in equally effective anesthesia and less maternal hypotension. Fifty term pregnant patients were randomly assigned to two study groups. In the HIGH-group combined spinal-epidural anesthesia was performed using 9.5 mg hyperbaric bupivacaine combined with 2.5 &mgr;g sufentanil. In the LOW-group combined spinal-epidural anesthesia was performed using 6.5 mg hyperbaric bupivacaine combined with 2.5 &mgr;g sufentanil. Demographic data, obstetrical data, visual analog scale score for pain, number of medical interventions for pain, maternal hemodynamics, and neonatal outcome were recorded. Patients in the HIGH-group experienced more pronounced and longer hypotensive periods as compared with the LOW-group. The mean lowest recorded systolic blood pressure was higher in the LOW-group (102 ± 16 versus 88 ± 16 in the HIGH-group; P < 0.05). More patients in the HIGH-group experienced hypotension compared with the LOW-group (68% versus 16%; P < 0.05). In the HIGH-group 15 patients required pharmacological treatment for hypotension compared with 5 in the LOW-group. Duration of effective anesthesia (block to cold sensation above or at T3) was longer in the HIGH-group as compared with the LOW-group (95 ± 25 versus 68 ± 18 min, respectively, P < 0.05). We conclude that small-dose spinal anesthesia (6.5 mg hyperbaric bupivacaine combined with sufentanil) better preserves maternal hemodynamic stability with equally effective anesthesia that is of shorter duration.
P2P Video-on-Demand: Steady State and Scalability

The fundamental P2P principle that downloading peers help other peers can be applied in the context of video-on-demand. This represents a demanding application combining aspects of other well-known P2P applications, i.e., live streaming and traditional file sharing. We seek to provide insight on fundamental questions about the performance and scalability of the system. A deterministic fluid model is derived that explicitly takes into account the video transfer and playback phases. The analytical results are complemented with extensive simulations from the corresponding stochastic model, as well as traces from a more realistic BitTorrent simulator.
Performance of Series Active Filter in low voltage distribution system with non linear loads

Investigation on the performance of Series Active Filter (SAF) in a low voltage distribution system with non linear loads is presented in this paper. Two control schemes like PI controller based Sinusoidal Pulse Width Modulation (SPWM) switching and hysteresis voltage controller based switching have been employed in this investigation. The percentage total harmonic distortion of the compensated load voltage has been considered as a measure for comparison. It has been observed from the simulation results under various loading conditions that the performance of SAF with hysteresis voltage controller is appreciable.

User behavior driven ranking without editorial judgments

We explore the potential of using users click-through logs where no editorial judgment is available to improve the ranking function of a vertical search engine. We base our analysis on the Cumulate Relevance Model, a user behavior model recently proposed as a way to extract relevance signal from click-through logs. We propose a novel way of directly learning the ranking function, effectively by-passing the need to have explicit editorial relevance label for each query-document pair. This approach potentially adjusts more closely the ranking function to a variety of user behaviors both at the individual and at the aggregate levels. We investigate two ways of using behavioral model; First, we consider the parametric approach where we learn the estimates of document relevance and use them as targets for the machine learned ranking schemes. In the second, functional approach, we learn a function that maximizes the behavioral model likelihood, effectively by-passing the need to estimate a substitute for document labels. Experiments using user session data collected from a commercial vertical search engine demonstrate the potential of our approach. While in terms of DCG, the editorial model out-perform the behavioral one, online experiments show that the behavioral model is on par --if not superior-- to the editorial model. To our knowledge, this is the first report in the Literature of a competitive behavioral model in a commercial setting
World Views - A Digital Archive Infrastructure for the Georg Eckert Institute for International Textbook Research

This paper outlines the aims of the newly established project World Views. The paper mainly shows the work still to be done, as the project has only recently started and is still in initial consolidation phase. It presents an overview of the planned infrastructure which will work as a digital archive in the textbook research field. Therefore a data middleware is to be implemented to enable integration and standardization of the various GEI data existing in diverse forms as well embed it in a broader semantic context, thus enabling "World Views". 1 (GEI) is the central research institution in this field. This role results in various new research projects which aim at promoting and using the textbook as a medium for research in the historical sciences generating large amounts of data which are especially characterized by their heterogeneity and furthermore, are bound to specific infrastructures tailored towards the different kinds of data requirements. It has become apparent that data curation has not been thoroughly considered in the projects' workflows. Standardization and archiving strategies have mostly been neglected. Up to this day this has resulted in collections containing valuable and important data which, however, exist parallel in separate environments with mostly no interfaces or linking possibilities. This goes against the "Good Scientific Practice" (8) postulated by the German Research Society (DFG) as the projects were funded by public money and the projects' data and results constitute valuable scientific knowledge worth of long-term curation and preservation so as to allow sustainable usage. Often no knowledge exists of the existing data even within the GEI thus resulting in double work. Even if data has been "discovered" by other researchers its reuse is often difficult or even impossible because of legacy or out-of-date data formats. Additionally, this situation has a negative effect on information retrieval and reuse by external parties since the GEI data neither is interlinked nor is it enriched with information from external sources. Despite its rich diversity and variety in terms of the available research data the GEI infrastructure lacks semantic contextualization. The new project World Views nationally funded (BMBF) and started in February 2015, is an effort to engage with the aforementioned issues. The absence of joint data storage is considered the main cause for this situation, which led to the decision to focus on establishing a suitable infrastructure, where the data integration of each existing project is made possible and which additionally serves as a standardizing basis for future project environments, eventually also leading to the implementation of a long-term curation strategy. With one joint search index which will work on all project data simultaneously the improvement of information retrieval is intended. 1 http://www.gei. de/home.html
Control of variable speed wind energy conversion system using a wind speed sensorless optimum speed MPPT control method

This paper presents a wind speed sensorless maximum power point tracking (MPPT) controller for variable speed wind energy conversion systems (WECS). The proposed controller generates at its output the optimum speed (OS) command for the speed control loop of the vector controlled machine side converter control system without requiring the knowledge of wind speed. The MPPT control of the WECS is achieved using optimum speed-power curve of the WECS taking into account the variation of the system efficiency while operating at various operating points due to the change in wind speed. The method is based on the fact that the optimum output power of a WECS at a certain wind speed depends upon the total mechanical power developed by the turbine and efficiency of the WECS at the corresponding OS of rotation of the turbine. The controller algorithm implementation requires the knowledge of turbine parameters and output power and air density as its inputs. The proposed concept is analyzed in a variable speed direct drive permanent magnet synchronous generator (PMSG) WECS. Experimental results show good tracking capability of the proposed controller.
ERP Implementation: A Technological Diffusion and Knowledge Transfer Perspective

As a recent IT innovation, Enterprise Resource Planning (ERP) system has become strategically important to organizations. Yet ERP is difficult to implement, high failure rate has been reported. Researchers and practitioners have pointed out that ignorance of knowledge transfer from consultancy to client was the reason for poor ERP implementation experience considering ERP’s complexity and high knowledge barrier on adopters. Although IT implementation and Innovation diffusion research has identified and empirically investigated various implementation success factors, few studies have empirically examined influential factors from knowledge transfer perspective. In this study, a model of ERP success antecedents is developed from the knowledge transfer, IT implementation, and innovation diffusion literatures. The purpose of this study is to investigate how the knowledge transfer related factors, together with well-established influential factors in both IT implementation and innovation literature, predict and explain the success of ERP implementation, which is complex and impose high knowledge barrier. A cross-sectional survey is being conducted in China to empirically examine this model.
Architectural patterns for problem frames

Problem frames provide a characterisation and classification of software development problems. Fitting a problem to an appropriate problem frame should not only help to understand it, but also to solve the problem (the idea being that, once the adequate problem frame is identified, then the associated development method should be available). The authors propose software architectural patterns corresponding to the different problem frames that may serve as a starting point for the construction of the software solving the given problem. It is shown that these architectural patterns exactly reflect the properties of the problems fitting to a given frame, and that they can be combined in a modular way to solve multi-frame problems. Alternative architectures to cope with specific system characteristics (e.g. distribution) are also provided.
