Aspect Category Detection in Product Reviews using Contextual Representation

Aspect category detection (ACD) is one of the challenging sub-tasks in aspect-based sentiment analysis. The goal of this task is to detect implicit or explicit aspect categories from the sentences of user-generated reviews. Since annotation over the aspects is time-consuming, the amount of labeled data is limited for supervised learning. In this paper, we study contextual representations of text segments in the reviews using the BERT model to better extract useful features from them, and train a supervised classifier with a small amount of labeled data for the ACD task. Experimental results obtained on Amazon reviews of six product domains show that our method is effective in some domains.
ARCam: an FPGA-based Augmented Reality Framework

Several solutions for Augmented Reality that use general purpose devices, like computers and handhelds, have recently been developed. In such devices, the processing is done by software, making it difficult to obtain the real time results without compromising resolution and frame rate, the use of high clock frequencies, and consequently leading to higher costs and power consumption. This paper describes the ARCam framework, which implements a platform based on Field Programmable Gate Array technology for Augmented Reality applications in the form of a dedicated hardware system. The ARCam solution is formed entirely by hardware components, including the one responsible for graphics rendering called Hardwire. In order to demonstrate the framework utilization and evaluate its feasibility, a number of image processing algorithms have been implemented and some Augmented Reality applications have been created using ARCam.
ANT COLONY ALGORITHM FOR NEAR-OPTIMAL ARRANGEMENT OF LINEAR MACHINE LAYOUT

Ant Colony System (ACS) is a meta-heuristic methodology, inspired by the behaviour of natural ants, which has already been applied to a numerous combinatorial problems. Flexible Manufacturing Systems cope with multi-product, usually small sized production. In this research work we investigate and apply an Ant Colony Optimization algorithm, which arranges the machines of a production line so that to minimize the total amount of backward flows. The experimental results show that a near optimal solution can be found exploiting only a small portion of the feasible solution space. Thus, the proposed algorithm indicates that it is a promising method, which can be applied to complex shop floor configuration for a generalised layout. Copyright © 2006 IFAC
Internal egg temperature in response to preincubation warming in broiler breeder and Turkey eggs

SUMMARY Variousmethods ofpreincubation warminghave beenused incommercial hatcheriesto increase hatchability, decrease incubation time, and increase embryonic blastoderm development. A study was conducted to determine the effect of preincubation warming and egg size on the warming rate of eggs. Three egg groupings were evaluated: small broiler breeder eggs (52 to 57 g), large broiler breeder eggs (64 to 69 g), and turkey eggs (74 to 107 g). The eggs were subjected to 2 temperature treatments. The conventionally incubated eggs were moved directly from storage (17.5°C) to the incubator (adjusted to 37.5°C). The preincubation warmed eggs were moved from the storage room to the preincubation room (28°C) for 12 h and then to the incubator. Internal egg temperature was measured once per minute to calculate the rate of warming. The warming rate potential (k value) differed for egg type and temperature treatment. The values for small and large broiler breeder eggs and turkey eggs were 0.0506, 0.0488, and 0.0471 kJ/min per kJ of energy in the egg, respectively. This study characterizes the maximum rate of temperature change that occurs when eggs are transferred from a storage or preincubation area to the incubator, creating baseline values for future work with the modification of hatchery management protocols. These data can contribute to more informed decisions regarding hatchery temperature profile strategies and their effect on the developing embryo.
Cytogenetic studies of Hynobiidae (Urodela). X Morphological variation of chromosome 10 in ten pond‐type Hynobius from Korea and Japan, with comments on phylogenetic relationships

We have studied karyotypes of ten pond‐type Hynobius collected from 51 localities: H. leechii from Korea, and H. tsuensis, H. dunni, H. nebulosus, H. abei, H. tokyoensis, H. takedai, H. lichenatus, H. nigrescens and H. retardatus from Japan. C‐banding analyses have been performed on the specimens from 38 out of the 51 localities. Among the karyological variations observed, chromosome 10 showed intra‐ and interspecific variations in many species, which we considered suitable for phylogenetic analysis. Our phylogenetic inferences concerning the morphological variation of chromosome 10 in ten pond‐type Hynobius are summarized as follows: 1) similarity in the morphology and the amount of heterochromatin of chromosome 10 in species found in close geographic proximity to each other indicates a close phylogenetic relationship; 2) species distributed in widely separated geographic areas and yet with similar amounts of heterochromatin on chromosome 10 have conserved this chromosomal pattern from a common ancestor; 3) the main evolutionary changes of chromosome 10 are decreases in the C‐positive region and transformation of the biarmed type of this chromosome to the uniarmed type by a pericentric inversion involving the C‐positive region.
IT/P2-10 Design and Analysis of the ECH Upper Port Plug Structure at ITER

The ECH Upper Port Plug at ITER is designed for controlling plasma instabilities, with a major emphasis on the stabilisation of neoclassical tearing modes, based on the injection a total of 20 MW mm-wave power at 170 GHz into the plasma. The required targeting of flux surfaces in the range of 0.65 to 0.93 (given in terms of the normalised poloidal flux surface coordinate) will be achieved by angular steering in the poloidal direction. The paper describes the integration of the mm-wave system into the upper port plug structure with a special focus given to the current front steering reference design. The launcher structure consists of the blanket shield module closing the gap in the blanket at the port; the port plug frame which houses the internal shield; the closure plate forming primary vacuum boundary; and the launcher back-end following the closure plate up to the final flange for the door placed for transfer to the hot cells. The shielding structure is essentially formed by the blanket shield module and the internal shield. For these subsystems, the conceptual design is presented which includes a specially adapted first wall panel welded to a double-walled housing, dedicated shield blocks formed in encased and/or solid configurations according to space requirements, and the internal shield integrated to the port plug frame. The nuclear shielding performance was analysed on the basis of 3D Monte Carlo calculations with the MCNP code for the radiation transport simulation and activation calculations with the FISPACT inventory code. It was shown for a fusion power of 500 MW and an operation over 0.5 full power years that all sufficiency criteria were fulfilled. Thermo-mechanical stresses in the first wall panel and the housing of the blanket shield module were analysed by FEM (“ANSYS”) calculations with transient loads for a typical plasma burn of 400 s using a simplified slice structure. 1. Overview of the structural components of the upper port plug For control of plasma instabilities, especially the stabilisation of neoclassical tearing modes, it is foreseen to inject a total of 20 MW mm-wave power at 170 GHz into the ITER plasma. The required targeting of the q=3/2 and q=2/1 flux surfaces will be achieved by angular steering in the poloidal direction. The mm-wave components are integrated into the upper port plug structure which consists of two separate units, namely the blanket shield module (BSM) forming the plasma-facing component and the launcher main structure, which includes the internal shield (cf. Fig. 1). BSM Flange connection

Anthropometric Variables as Predictors of Speed in Amateur Football Players

Speed is one of the important technical skills in football. Speed define as the ability of an athlete to move their self from one place to another with maximum velocity. The purpose of this study is to determine the correlation between selected anthropometric variables (body weight, height, BMI, body fat percentage, waist circumference, hip circumference, calf circumference, thigh circumference, ankle circumference, leg length, foot length and fat free mass) with speed ability. The other purpose is to establish a regression equation for predicting speed ability based on anthropometric variables. 15 participants from UiTM Perlis FC, aged 20.87 ± 1.19 years were recruited for this study. The selected anthropometric variables measured by different tests and instruments. The 20 m dash test used to measure speed ability. The results showed a significant relationship was found between speed ability and body weight (r = 0.62), height (r = 0.71), waist circumference (r = 0.51), leg length (r = 0.52), foot length (r = 0.73), and fat free mass (r = 0.67) p ≤ 0.05. The Regression equation Speed Ability = -7.330 + 0.010 (Body Weight) + 0.058 (Height) + 0.028 (Waist Circumference) – 0.017 (Leg Length) + 0.095 (Foot Length) – 0.056 (Fat Free Mass). It was concluded that the formula suggested in this study, can be used to determine the speed ability of amateur football players. Coaches and players should focus on the development of anthropometric variables associated with the speed to improve the speed ability.
Identification, inheritance and gene mapping of resistance to a virulent Soybean mosaic virus strain SC15 in soybean

With 1 figure and 3 tables Abstract Soybean mosaic virus (SMV) is one of the major pathogens for soybeans worldwide. Among the 21 strains identified under uniform identification system in China, SC15 can infect all 10 of the differentials, is the most virulent strain and has been prevalent especially in Southern China. In this study, 10 elite accessions resistant to SC15 were identified from 205 soybean lines. P1, P2, F1, F2 and 200 recombinant inbred lines (RIL) of the cross ‘RN-9’ (resistant, R) ×‘7605’ (susceptible, S) were used to study inheritance of resistance to SC15. F1 was identical to ‘RN-9’, F2 segregated in a 3R : 1S phenotypic ratio, whereas RILs segregated in a 1R : 1S genotypic ratio. This indicated that a single dominant gene, designated as RSC15, conferred the resistance. A genetic linkage map of a segment of C2 linkage group was constructed using SSR markers identified by bulked segregant analysis of RIL population, where RSC15 was mapped between Sat_213 and Sat_286 with distances of 8.0 and 6.6 cM to the respective flanking markers.
NET WORK: A PRACTICAL GUIDE TO CREATING AND SUSTAINING NETWORKS AT WORK AND IN THE WORLD

BY WEAVING TOGETHER various concepts, including social networks, social capital, complexity theory, and knowledge management, Patti Anklam aims to introduce another integrative concept termed net work, which by her definition refers to individuals’ endeavor to understand, sustain, and work effectively in networks. In short, Anklam is keen to promote the idea that normal individuals and leaders alike should learn how to employ the network lens to make sense of the networks they are engaged in. Specifically, Anklam posits that social networks, as a form of organization, embody a complex system consisting of interconnected individual members, who self-organize and work together to create value-producing capabilities of the network. The outcomes derived from this investment in, as well as understanding of, networks bring benefits to individuals and organizations, namely, social capital. Undoubtedly, communication plays a crucial role in these self-organizing and value-producing processes.
Simultaneous Gate and Subthreshold Leakage Reduction Techniques

In this paper we will discuss the effects of gate and subthreshold leakage reduction techniques on arbitrary circuits. According to the present scaling trends, power will become a limiting factor in future VLSI technologies. With the scaling down of transistors leakage power becomes a significant portion (more than 40%) of the total power consumed in modern chips. Many leakage reduction techniques ignore gate leakage although it makes up a large portion of the total leakage. In order to optimize the leakage power simultaneous gate and subthreshold leakage reductions are needed. In our analysis we used both input vector control and MTCMOS to observe the effects on leakage reduction. Using our heuristic for finding the optimal input vector of any arbitrary circuit we saw up to 28% reductions in total leakage current. We then used MTCMOS to find an optimal V T for a given process size which maximized the current-delay product. Finally we combined the input vector control and the MTCMOS for further leakage reductions seeing up to 45% reduction in gate current.
Comparison of Structural Colors Achieved by Laser-Induced Periodic Surface Structures and Direct Laser Interference Patterning

Engraving surfaces with holographic features is not only used for decorative applications, but also for protecting products from counterfeit and piracy. This structural coloration can be produced on large areas at high-throughput using laser-based methods such as Direct Laser Interference Patterning and Laser-Induced Periodic Surface Structuring (LIPSS). In this contribution, both technologies were used to generate diffraction gratings on stainless steel with different processing parameters. Then, the resulting spectral reflectances were quantitatively compared and correlated to topographical characteristics determined by scanning electron microscopy and atomic force microscopy. Overall, the DLIP treated samples showed up to 42% higher diffuse reflectivity than the LIPSS samples when illuminated with a green laser diode. However, the LIPSS textures were less spectral dependent, probably due to their broader distribution of spatial periods and structure heights. These findings could also be appreciated with the naked eye as the samples patterned with LIPSS have a matte aspect with a homogeneous coloration, whereas the DLIP samples had a glossy appearance with brighter colors.
AN EMPIRICAL EXAMINATION OF THE EVALUATIVE UTILITY OF DESIGN AURALIZATION

This paper explores the degree to which subjective assessments of the acoustical properties of a real space can be reproduced by assessments that are based on computational auralization. Toward this end, three spaces with different functional and acoustical characteristics were selected. These spaces were evaluated by a group of test participants. A second group of test participants evaluated high-quality auralizations of the spaces. The results of the two groups were compared to empirically determine if auralizations can reliably represent real spaces for acoustical quality evaluation purposes.
An N-Linked Glycoprotein with α(2,3)-Linked Sialic Acid Is a Receptor for BK Virus

ABSTRACT BK virus (BKV) is a common human polyomavirus infecting >80% of the population worldwide. Infection with BKV is asymptomatic, but reactivation in renal transplant recipients can lead to polyomavirus-associated nephropathy. In this report, we show that enzymatic removal of α(2,3)-linked sialic acid from cells inhibited BKV infection. Reconstitution of asialo cells with α(2,3)-specific sialyltransferase restored susceptibility to infection. Inhibition of N-linked glycosylation with tunicamycin reduced infection, but inhibition of O-linked glycosylation did not. An O-linked-specific α(2,3)-sialyltransferase was unable to restore infection in asialo cells. Taken together, these data indicate that an N-linked glycoprotein containing α(2,3)-linked sialic acid is a critical component of the cellular receptor for BKV.
The reporting of Adjusted EBITDA and stock Markets: The Case of Canada and France

In this paper, we investigate whether adjusted EBITDA, a non-GAAP metric, provides market participants with relevant information as measured by a reduction in information asymmetry between managers and investors (share price volatility) and by its value relevance beyond the release of GAAP earnings. Toward that end, we compare firms from two countries with contrasting institutional regimes, Canada and France. Our analyses take into account the fact that firms self-select into disclosing non-GAAP information. Our results show that Adjusted EBITDA reduces volatility both in Canada and in France, but in a similar fashion than components of GAAP earnings. We observe also that Adjusted EBITDA exhibits the same value relevance in Canada and France, but its impact seems greater than components of GAAP earnings. Canadian firms are much more likely to provide Adjusted EBITDA disclosure than French firms. In addition, CEO power as well as analysts and institutional investors’ monitoring reduce the likelihood of providing non-GAAP disclosure while free float and firm size affect it positively.
Zebra Finch Glucokinase Containing Two Homologous Halves Is an In Silico Chimera

Chimerical nature of the gene annotated as Zebra finch (Taeniopygia guttata) glucokinase (hexokinase IV) has been proved in this study. N-half of the protein encoded by that gene shows similarity with glucokinase from other vertebrates, while its C-half shows similarity with C-halves of hexokinases II. We mapped 7 new exons coding for N-half of hexokinase II and 4 new exons coding for glucokinase of Zebra finch. Finally, we reconstructed normal genes coding for Zebra finch glucokinase and hexokinase II which are situated in “head-to-tail” orientation on the chromosome 22. Because of the error in gene annotation, exons encoding N-half of normal glucokinase have been fused with exons encoding C-half of normal hexokinase II, even though they are separated from each other by the sequence 98066 nucleotides in length.
Biomass yield and chemical composition of Macroptillium autro purpureum and Stylosanthes hamata

The main aim of this research was to find out the biomass yield and chemical composition of two commonly used tree fodders i.e. Macroptilium atropurpureum and Stylosanthes hamata grown in veterinary college hebbal, Bengaluru, Karnataka. The tree fodders were grown and samples were collected and analyzed for DM (Dry Matter), CP (Crude Protein), Ash, EE (Ether extract), NDF (Neutral Detergent Fibre), ADF (Acid Detergent Fibre), ME (Metabolizable energy) and protein yield as well as biomass yield from these tree fodders over a period of one year. The study revealed that biomass yield of Macroptilium atropurpureum and Stylosanthes hamata were 78.37 and 76.34 t/ha/yr respectively. The Proximate composition which includes crude protein, ether extract showed 13.73% and 15.07%, 2.45% and 2.02% respectively. NDF value and Metabolizable energy of these both fodder is around 47.78 and 54.42, 9.58 and 8.41MJ/kg respectively. Protein yield Macroptilium atropurpureum showed lower of 2.24 t/ha/yr compared to 3.37 t/ha/yr by Stylosanthes hamata.
Movements of translocated captive-bred and released Critically Endangered kaki (black stilts) Himantopus novaezelandiae and the value of long-term post-release monitoring

Abstract Translocation outcomes for mobile species can be affected by post-release movement of individuals, yet few population reintroduction and supplementation projects consider propensity to move as a selection criterion when selecting individuals to release or sites for release. We investigate the influence of release age (juvenile or subadult), the size of the release group and the size of the wild population at the release site on movements of Critically Endangered kaki (black stilt) Himantopus novaezelandiae. Over 460 subadult and juvenile kaki have been released during 12 years at nine sites in the Waitaki Basin, New Zealand, with the aim of supplementing specific sub-populations. Among the survivors that reached breeding age, 32% of released kaki ended up away from their release sites, i.e. away from the subpopulations they were intended to augment and 15% of these birds were in unmanageable areas where monitoring cannot take place. Kaki released as juveniles (2–3 months) made more long moves and moved further from the release site during 2 months post-release. The presence of conspecifics affected behaviour after release: released birds were more likely to remain closer to the release site when the size of the wild population at the release site was large, and kaki released in larger groups were more likely to make more longer moves. Despite initial differences in mobility, long-term monitoring revealed equal proportions of 2-year old survivors that had been released as juveniles and subadults returning and being observed consistently at release sites, emphasizing the value of long-term monitoring in informing release strategies for population restorations.

Middle Managers (MM) are key figures for firm ability to gain and sustaining competitive advantage (CIT). Their training activity can be seen as an important tool for improving and upgrading managerial practices to sustain firm strategy that is strictly related with its competitive advantage. The present research aims at deepening the analysis undertaken within the literature branch concerned with the effects of training of middle managers on direct measures of firm performance as measured by profitability indices and productivity. In particular, the study focuses on middle management continuing vocational training in the Italian manufacturing sector in the time window 2006-2011. The study is based on a novel database containing balance sheet data together with exhaustive information about the training undertaken by managers working in the sample of companies available – provided by Fondirigenti. The study extends and deepens the existing literature based on two key aspects: (a) the possibility to disaggregate the training activity along two dimensions: the methodology used and the field in which the training is done; (b) the opportunity to use different more precise measures of training, namely the cost in euros and the time devoted to the activity. We empirically test, using regression models based on GMM estimation, a set of research hypotheses and we find support for the five following hypotheses: (H1) Middle management continuing vocational training has an effect on performance indicators namely ROI, ROE and TFP, Moreover the first two show a TMGT effect; MM training is more effective for: larger firms, older firms (H2 and H3); external resources are important in making MM training effective (H3); different methodologies of training have heterogeneous effects on performance: experiential methods are more effective than relational and front lesson methods (H5). We discuss the results and derive some policy conclusions.
