The High Time Resolution Universe survey - XI. Discovery of five recycled pulsars and the optical detectability of survey white dwarf companions

We present the discovery of a further ve recycled pulsar systems in the midGalactic latitude portion of the High Time Resolution Universe (HTRU) Survey. The pulsars have rotational periods ranging from 2 ms to 66 ms, and four are in binary systems with orbital periods between 10.8 hours and 9.0 days. Three of these binary systems are particularly interesting; PSR J1227 6208 has a pulse period of 34.5 ms and the highest mass function of all pulsars with near-circular orbits. The circular orbit suggests that the companion is not another neutron star, so future timing experiments may reveal one of the heaviest white dwarfs ever found (> 1.3 M ). Timing observations of PSR J1431 4715 indicate that it is eclipsed by its companion which has a mass indicating it belongs to the redback class of eclipsing millisecond pulsars. PSR J1653 2054 has a companion with a minimum mass of only 0:08 M , placing it among the class of pulsars with low-mass companions. Unlike the majority of such systems, however, no evidence of eclipses is seen at 1.4 GHz.
Understanding The Implications Of A Trending Popular Culture: The Online Food Review

Online food reviews as a part of popular culture instigated by the propagation of the Internet are increasingly used by food industries to help consumers in creating decision making: “to buy or not to buy”. Some food industries are moving out from classical ways of word-of-mouth and printed or digital advertisements into online food reviews similar to content reviews of restaurants, hotels, films, music, and also Applications. The study uses qualitative exploratory methods and Focus Group Discussion to examine consumers’ behaviors in making a decision before eating what and where. The findings suggest that consumers are also influenced by the quality of information, ratings, and services. Findings indicate that consumer involvement in online food reviews provide challenges that able small and big food industries overcome the barrier arising from the lack of doing business in popular culture. Keywords: online food review, restaurant industry, popular culture, decision making, consumer
High Resolution Stream Network in Haji Dam Watershed

The main objective of this research is to find landscape structure of watershed by using the method of hydrological simulations. A watershed is a basic physical entity of the landscape and most processes related to the movement and/or quality of the water occur in the catchment or sub-catchment areas of the watershed. The basic tool used to analyze the landscape of a watershed is Digital Elevation Model (DEM) in order to obtain the Drainage Direction Matrix (DDM) by which is possible to obtain stream network structure. One of the relevant applications of the DDM is to identify possible sources of water pollution by isolating and tracking back the pollutants inside a river network. The main contribution of this study is to present a high resolution stream network in Haji Dam watershed using 10m DEM. By calculating Horton ratios (Rb = 4.45, Rl = 1.93) and fractal dimensional parameters (d = 1, D = 1.97) it is been demonstrated the importance of a high resolution DDM for the precise comprehension of the watershed system and the correct interpretation of it relief, topography and complexity.
Control of Redundantly Actuated PKMs for Closed-Shape Trajectories Tracking with Real-Time Experiments

: This paper deals with closed-shape geometric reference trajectories generation and dynamic control of redundantly actuated parallel kinematic manipulators. Geometric trajectories if generated by means of trigonometric functions may show inherent discontinuities regarding velocities and/or accelerations which may cause problems for the drives. In order to overcome this issue and to generate C 2 continuous refernce trajectories, we propose a novel technique consisting of modifying the motion proﬁlewhilepreservingtheoverallgeometricshapeofthetrajectoryintheoperational space. Regarding the control strategy and to deal with the actuation redundancy, an extended version of the PD controller with computed feedforward is proposed. The computed control inputs, before being applied to the actuators, are ﬁrst projected using a regularization matrix based on the manipulator’s kinematics in order to remove the antagonistic internal forces. The overall proposed strategy including the trajectory generator as well as the controller are experimentally validated on the Dual-V robot, a three-degree-of-freedom redundantly actuated parallel kinematic manipulator developed in our laboratory.
Psychology of development of moral reasoning: Problem-oriented overview of the field

First and foremost, this paper provides a short historical reminder of the emergence of the field of psychology of development of moral reasoning. In the second part of the paper, the author offers a problem-oriented overview of the field, that is, one possible classification of particular groups of problems for empirical research. This overview does not only point out to the problems that were more and that were less studied (e.g. evaluative moral judgment and reasoning, distinguishing between moral and extra-moral rules and norms) and to those that were relatively neglected (i.e. understanding moral situations), but also to the problems that psychologists did not even recognize as research problems. Such are the problems of development of moral concepts, meaning of moral words etc. Finally, the author also points out to the fact that this classification could be taken as one way to define the field, that is, the way to determine the boundaries of its subject of studying.
Unifier register to protect an efficient modular exponentiation algorithm

Simple power analysis (SPA) attacks are widely used against several cryptosystems, principally against those based on modular exponentiation. Many types of SPA have been reported in the literature in the recent years. There is a real necessity to eliminate the vulnerabilities of cryptosystems, such as CRT-RSA or the Elliptic Curve Cryptosystem, that make them susceptible to these attacks. There are many modular exponentiation algorithms that try to reinforce the security of these systems, of which one was proposed by Da-Zhi et al.Da-zhi’s algorithm was presented as a secure and efficient countermeasure against side channel attacks; however, recently it was shown that its security can be defeated. In this paper, a means of protecting the algorithm is presented. The proposed technique can be applied in any algorithm that computes dummy operations through its execution.
A Comprehensive Empirical Correlation for prediction of Supersolubility and Width of the Metastable Zone in Crystallization

Prediction of supersolubility and the width of the metastable zone has been a major concern among the workers in the field of industrial crystallization. Operation of crystallizers under the optimum supersaturation low enough to attain the desired product quality (Median Particle Size, Crystal Size Distribution (CSD), Shape, Purity) being one motif. The inherent relationship between the subject and the most fundamental concepts of crystallization being the other. Studying the conditions of primary homogenous nucleation and the crystal growth kinetics has been conducted for a wide range of inorganic materials. A simple probabilistic term called chance of having the desirable species congregation, has been introduced to account for the effect of solution composition. A semi-empirical model has been developed for occasions where primary homogenous nucleation occurs at a specified undercooling rate (0.2 o C/hr). The model has been found to satisfy the experimental results obtained for 28 inorganic systems under various conditions. Theconcept may be equally applicable in nucleation of organic materials and for cases where liquid nuclei (such as rain droplets) are formed.
MedMentions: A Large Biomedical Corpus Annotated with UMLS Concepts

This paper presents the formal release of {\em MedMentions}, a new manually annotated resource for the recognition of biomedical concepts. What distinguishes MedMentions from other annotated biomedical corpora is its size (over 4,000 abstracts and over 350,000 linked mentions), as well as the size of the concept ontology (over 3 million concepts from UMLS 2017) and its broad coverage of biomedical disciplines. In addition to the full corpus, a sub-corpus of MedMentions is also presented, comprising annotations for a subset of UMLS 2017 targeted towards document retrieval. To encourage research in Biomedical Named Entity Recognition and Linking, data splits for training and testing are included in the release, and a baseline model and its metrics for entity linking are also described.
Implications of food aid and remittances for West African food import demand

The influence of food aid and remittances on West African food import demand is evaluated using a Central Bureau of Statistics (CBS) model. Our results show that imports of oilseeds and the rest of the agricultural products category are highly price elastic, and that fruit and vegetables and dairy products are least responsive to price changes. Food aid did not influence West African food imports, but remittances were found to be statistically significant in determining food imports. The influence of remittances was particularly prominent in oilseed import demand.
Mesozoic and Cenozoic tectonic history of the central Chinese Tian Shan: Reactivated tectonic structures and active deformation

The present‐day topography of the Tian Shan range is considered to result from crustal shortening related to the ongoing India‐Asia collision that started in the early Tertiary. In this study we report evidence for several episodes of localized tectonic activity which occurred prior to that major orogenic event. Apatite fission track analysis and (U‐Th)/He dating on apatite and zircon indicate that inherited Paleozoic structures were reactivated in the late Paleozoic‐early Mesozoic during a Cimmerian orogenic episode and also in the Late Cretaceous‐Paleogene (around 65–60 Ma). These reactivations could have resulted from the accretion of the Kohistan‐Dras arc or lithospheric extension in the Siberia‐Mongolia zone. Activity resumed in the late Mesozoic prior to the major Tertiary orogenic phase. Finally, the ongoing deformation, which again reactivates inherited tectonic structures, tends to propagate inside the endoreic basins that were preserved in the range, leading to their progressive closure. This study demonstrates the importance of inherited structures in localizing the first increments of the deformation before it propagates into yet undeformed areas.
Evaluation of follicular lymphoid depletion in the Bursa of Fabricius: an alternative methodology using digital image analysis and artificial neural networks

Fifty Bursa of Fabricius (BF) were examined by conventional optical microscopy and digital images were acquired and processed using Matlab® 6.5 software. The Artificial Neuronal Network (ANN) was generated using Neuroshell® Classifier software and the optical and digital data were compared. The ANN was able to make a comparable classification of digital and optical scores. The use of ANN was able to classify correctly the majority of the follicles, reaching sensibility and specificity of 89% and 96%, respectively. When the follicles were scored and grouped in a binary fashion the sensibility increased to 90% and obtained the maximum value for the specificity of 92%. These results demonstrate that the use of digital image analysis and ANN is a useful tool for the pathological classification of the BF lymphoid depletion. In addition it provides objective results that allow measuring the dimension of the error in the diagnosis and classification therefore making comparison between databases feasible.
Analysing Seq-to-seq Models in Goal-oriented Dialogue : Generalising to Disfluencies

Data-driven dialogue systems are still far from understanding natural dialogue. Several aspects of natural language make it hard to capture in a system, such as unpredictability, mistakes and the width of the domain. In this thesis we take a step towards more natural data by examining disfluencies (i.e. mistakes). We test sequence to sequence models with attention on goal-oriented dialogue. Sequence to sequence models were chosen to overcome the unknown aspect of the mistakes, since they are known for their ability to generalise to unseen examples. The models are tested on disfluent dialogue data, the bAbI+ task, in addition to normal goal-oriented dialogue data, the bAbI task. In contrast to previous findings with memory networks, we find that the sequence to sequence model performs both the bAbI tasks as the bAbI+ task well achieving near perfect scores on both tasks. A slight decrease in performance is noticed when introducing disfluencies only to test data, only 80% accuracy is measured in this condition. This is surprising because memory networks are very similar to sequence to sequence models with attention. The results of the main experiment suggest that sequence to sequence models learn to parse disfluencies. Attention visualisation results suggest that the bAbI+ model does indeed learn to pay attention to disfluencies in a meaningful way. Even though attention shows that the model is aware of disfluencies, further analyses using diagnostic classifiers and diverse inputs suggest that the encoder is not learning to parse disfluencies, as we expected, but functions more as a memory. The decoder in turn appears to access the encoder as this memory using the attention mechanism, which proved crucial to learning the bAbI tasks.
Intelligent Transformer: Possibilities and Challenges

Intelligent Transformer: Possibilities and Challenges This paper covers the concept of an intelligent transformer that is a good candidate to replace a conventional low frequency transformer in the microgrids. As the power production and consumption can vary in a wide range, the new substations have to meet many requirements to guarantee reliable energy management in the autonomous networks. Different topologies of intelligent transformers can be used to meet these requirements. Therefore the advantages and disadvantages of the existing topologies were analyzed. The future trends and challenges are also discussed.
Influence of weight grade on shell characteristics of marketed hen eggs.

In egg marketing, shell breaking during both packaging and delivery is the main cause of losses. As a part of a wider study devoted to the description of commercial eggs quality, eggshell characteristics were evaluated as a function of the weight grades established by the European regulation. To this end, 27 samples of commercial grade A eggs, belonging to S, M, L, and XL weight grades, laid by cage hens and purchased in different retail shops in Northern Italy, were analysed. Each sample included at least 36 eggs from the same lot. The following parameters were determined: cracks percentage; egg weight, surface area, equator diameter, height and shape index; percentage of eggshell; eggshell index and thickness. Breaking strength of eggshell was evaluated using an Instron dynamometer equipped with a plate and a probe (8 mm diameter) as compression/penetration elements. Differences among weight grades were significant (p≤0.001) for egg weight, surface area, height and equator diameter. Instead, shape index values of different weight grade eggs partially overlapped. A significant (p≤0.001) decrease of eggshell percentage was observed as egg weight increased, along with a reduction of eggshell thickness in XL eggs compared with M and L eggs. Eggshell thickness was lower at the broad pole than at the narrow pole and the equator. Penetration breaking strength was significantly higher in grade S eggs (43.4 N), while XL eggs leaned to the lowest average value (35.5 N). Furthermore, XL eggs showed the highest average percentage of cracked eggs. The use of different penetration/compression elements highlighted several significant correlations between breaking strength and various egg geometrical and structural parameters.
The Effect of Initial Endowments in Experimental Auctions

We report the results of an experiment designed to test whether initial endowments affect value estimates elicited from experimental auctions. Comparing bids for one unit of a good, two units of a good, and a second unit of a good when endowed with the first unit, we find that willingness to pay for the second unit of a good is, on average, as much as 75% higher when endowed with the first unit. We go on to advance two theories that could potentially reconcile our results with neoclassical consumer theory.
CIRP Conference on Modelling of Machining Operations Prediction of the 3 D Surface Topography after Ball End Milling and its Influence on Aerodynamics

The surface topography of milled workpieces often defines their performance. One example is blades in turbine engines, where the topography defines the flow losses. This type of complex goods is often machined by ball end mills, either for manufacture or repair. The literature offers various model types to predict the surface topography in order to design a machining process without prior experiment. The most accurate models use the real kinematics of the process and blend the tool with the workpiece. But this type of surface prediction ignores the differences between the reality and the simulation due to vibrations, tool chipping etc. This paper presents a combined approach using the kinematic topography from the machining simulation and adds a stochastic topography based on empirical data. It could be shown, that the usage of the stochastic topography greatly affects the flow losses and thus cannot be ignored. © 2015 The Authors. Published by Elsevier B.V.

Gene expression of a putative glutathione S-transferase is responsive to abiotic stress in embryogenic cell cultures of Cyclamen persicum

Background: Cyclamen persicum is an economically important ornamental crop that is propagated exclusively through seeds as vegetative propagation using cuttings is not possible. Therefore a micropropagation method through somatic embryogenesis is of high interest; however the method suffers from low reliability concerning quality and quantity of the produced plantlets. A crucial step of the protocol is the removal of plant growth regulators (PGRs) that triggers embryo development. In order to get a better insight in this crucial step of the propagation process, a gene expression analysis has been set up using five different genes of glutathione S-transferases (GST) as these are known to be auxin responsive as well as stress reactive. Results: One out of the five genes of glutathione S-transferases (CpGST1) displayed a clear down-regulation 72 hrs after removal of PGRs compared to 4 hrs after, implying auxin responsiveness. However, a more detailed analysis including the time points 0, 4 and 72 hrs revealed an initial strong up-regulation after 4 hrs before it was down-regulated after 72 hrs. In comparison fold-changes of the additional four GST-genes were marginal. Comparing cultures on semisolid medium to that in suspension, transcript abundances of CpGST1 were clearly decreased in suspension culture. Conclusions: Against the initial hypothesis CpGST was not auxin responsive but stress reactive, probably especially indicating drought stress imposed on the cells upon transfer from submerged suspension culture to semisolid medium. Mechanical stress caused by shaking of suspensions cultures seemed to be less important.
Identifying Citation Contexts: a Review of Strategies and Goals

English. The Citation Contexts of a cited entity can be seen as little tesserae that, ﬁt together, can be exploited to follow the opinion of the scientiﬁc community towards that entity as well as to summa-rize its most important contents. This mo-saic is an excellent resource of information also for identifying topic speciﬁc syn-onyms, indexing terms and citers’ moti-vations, i.e. the reasons why authors cite other works. Is a paper cited for comparison, as a source of data or just for additional info? What is the polarity of a citation? Different reasons for citing reveal also different weights of the citations and different impacts of the cited authors that go beyond the mere citation count met-rics. Identifying the appropriate Citation Context is the ﬁrst step toward a multi-tude of possible analysis and researches. So far, Citation Context have been deﬁned in several ways in literature, related to different purposes, domains and applications. In this paper we present different dimensions of Citation Context investigated by researchers through the years in order to provide an introductory review of the topic to anyone approaching this subject.

On the search of efficient AQM for large delay networks

The main idea of all Active Queue Management algorithms, is to notify the TCP sender about incoming congestion by dropping packets, to prevent from the buffer overflow, and its negative consequences. However, most AQM algorithms proposed so far, neglect the impact of the high speed and long delay links. As a result, the algorithms’ efficiency, in terms of throughput and/or queue stability, is usually significantly decreased. The contribution of this paper is twofold. First of all, the performance of the well known AQM algorithms in high speed and long delay scenarios is evaluated and compared. Secondly, a new AQM algorithm is proposed, to improve the throughput in the large delay scenarios and to exclude the usage of random number generator.
None-platinum electrode catalysts and membranes for highly efficient and inexpensive H2 production in microbial electrolysis cells (MECs): A review

Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater. Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employing a low-cost, stable and high efficient cathode to replace platinum catalyzed cathode (Pt/C) is the greatest challenge for large-scale industrialization of MEC. Numerous studies have demonstrated that the performance of MEC directly depends on the kinetics of the anode and cathode reactions within the electrolysis cell, with the performance of the electrode catalyst highly affected by the materials they are made from. In a relatively short space of time, a wide range of electrode materials have been tested to amplify the performance of MECs, such as carbon-based electrode catalysts have emerged as promising electrode materials for both anode and cathode construction. Composite materials have also shown to have the potential to become materials of choice for electro-catalyst manufacture. More recently, various transition metal oxides and alloys have been extensively examined as alternatives to conventional expensive noble-metals like platinum for hydrogen evaluation reaction (HER) in MECs. Numerous studies have confirmed that stainless steel, Ni alloys, and Pd nanoparticle decorated cathode are worth mentioning and have very good efficiency. In the present article, we present a comprehensive review centered on the development of a low-cost and high efficient electrode materials and membrane to boost the performance of MECs, including anode, cathode, and membrane.
