A Set of Space-Time Block Codes for the High-Rate Transmission Scheme with One Information Bit

In [1], the authors have proposed one high rate transmission scheme for Space-Time Block Codes (STBC) without additional system source such as power, bandwidth and time slot. To maintain the full rank property of the coding gain matrix, we propose a set of STBCs for 4 transmit antennas transmission to transmit one additional information bit achieving rate-9/8. Another orthogonal STBC code with rate-1 is proposed in this paper within the set. It shows by computer simulation results that by employing the set of STBCs, it achieves better bit error rate (BER) performance and throughput than that of [1] with a valid BER improvement at the high SNR region above 20dB.
cROVER: Context-augmented Speech Recognizer based on Multi-Decoders' Output

Most researchers agree that one of the most promising approaches for the problem of reducing the Word Error Rate (WER) in large vocabulary speech transcription, is to combine two or more speech recognizers and then generate a new output, in the expectation that it provides a lower error rate. The research work proposed here aims at enhancing and boosting even further the performance of the wellknown Recognizer Output Voting Error Reduction (ROVER) combination technique. This is done through its integration with an error filtering approach. The proposed system is referred to as cROVER, for context-augmented ROVER. The error detection technique consists of spotting semantic outliers in a given decoder‘s transcription output. Due to the fact that most error detection techniques suffer from a high false positive rate, we propose to combine the error filtering techniques to compensate for the poor performance of each of the individual error classifiers.
A circumscribed refractory access disorder: A verbal semantic impairment sparing visual semantics

Abstract We report the case of a patient (AZ) with a semantic refractory access dysphasia. On matching-to-sample tests assessing comprehension of the spoken word, AZ shows all the hallmarks of a refractory access disorder, namely inconsistent performance on repeated testing and sensitivity to both presentation rate and the semantic similarity between competing responses. However, on tasks examining her visual knowledge, such as matching two structurally different exemplars of the same item, AZ's performance is quantitatively and qualitatively different. In a series of experiments testing her knowledge of animate and inanimate items, AZ demonstrated significantly worse performance with verbal-visual matching than with visual-visual matching. Furthermore, response accuracy was observed to decrease with successive probing of an item in the verbal conditions but not the visual conditions. We also demonstrate that this discrepancy cannot be explained on the basis of either task difficulty or presentation rate. We attribute our results to a build-up of refractoriness in the systems mediating verbal comprehension whilst those underlying visual comprehension remain unaffected. We argue that our data speak against a unitary amodal semantic system and in favour of at least partially separate verbal and visual semantic processing.
Belief in a just world , justice judgments , and their functions for prisoners

This study focuses on the relationship between the experience of justice, belief in a just world (BJW), and the feelings of adult male prisoners, taking into account aspects of their personal background and criminal career. Our sample comprised 100 male prisoners from a German detention center. Regression analysis provided evidence for the assimilation function of the BJW. Specifically, high believers interpreted events in their life as being more just; e.g., they evaluated the legal proceedings leading to their conviction, their interpersonal treatment by their prison guards, and decisions on prison affairs as more just. Moreover, high believers reported better well-being and were less likely to express anger in the form of outburst behavior. Finally, a sense of being treated justly by prison guards was particularly important in explaining well-being. This pattern of results persisted when controlling for social desirability and for criminal and personal background. We discuss the role of BJW and especially interpersonal justice as a resource for adaptive social behavior and subjective wellbeing.
A new magnetic field measurement based on Polarization Dependent Loss of reflection light in triangular grating

A new magnetic field measurement with fiber grating based on the polarized effect was proposed. The linear relationship between the Polarization Dependent Loss of transmission light and magnetic field in circular birefringent grating is proved. We can get the magnetic field from measuring the peak value of PDL. But the measurement performance of triangular grating is better than the uniform grating, the reflection spectrum is usually deeper than the transmission spectrum. To improve the sensitivity of magnetic field measurement, we proposed a new measurement for magnetic field based on Polarization Dependent Loss of reflection light on triangular grating and analysed the influencing factors on measurement performance.
Activity Study Antioxidant Extracts Of Flowers and Grains of Chamaerops Humilis L . Western Morocco

This study aims to evaluate the phytochemical content and antioxidant activity of the extracts of flowers and grains, with two solvents hexane and ethanol, harvested in the region of Chaouia-Ouardigha west of Morocco. However, total phenols are measured by the spectrophotometric method and the antioxidant activity was assessed using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH •) as a free radical scavenger, taking as witness antioxidant ascorbic acid. The results revealed a wealth of total phenols ethanol extracts of EEG grains and ethanol extracts of flowers by EEF content respectively 533,14 mg /g and 524,06 mg /g compared to other hexane extracts of EHG grains and flowers EHF . While the extracted EEG reveals a percentage of inhibition of approximately 84.05% to the effective concentration IC50 2,38μg / ml with a reaction time in TEC50 balance of 25 min and a percentage of the antiradical activity of 25%, which shows lower than that of vitamin C (68%). The antioxidant activity of the other three extracts remains significantly lower than that of the EEG extract.
Remote control of the artificial arm model using 3D hand tracking

Modern sensing technologies create new possibilities to control mobile robots without any dedicated manipulators. In this article authors present a novel method that enables driving of the Mindstorms NXT artificial arm with Microsoft Kinect, using gesture recognition. To imitate movement of an artificial robotic arm, an algorithm of the human-computer interaction is employed using skeleton tracking and gesture control in 3D space.

Remote ischemic preconditioning does not prevent acute mountain sickness after rapid ascent to 3,450 m.

Remote ischemic preconditioning (RIPC) has been shown to protect remote organs, such as the brain and the lung, from damage induced by subsequent hypoxia or ischemia. Acute mountain sickness (AMS) is a syndrome of nonspecific neurologic symptoms and in high-altitude pulmonary edema excessive hypoxic pulmonary vasoconstriction (HPV) plays a pivotal role. We hypothesized that RIPC protects the brain from AMS and attenuates the magnitude of HPV after rapid ascent to 3,450 m. Forty nonacclimatized volunteers were randomized into two groups. At low altitude (750 m) the RIPC group (n = 20) underwent 4 × 5 min of lower-limb ischemia (induced by inflation of bilateral thigh cuffs to 200 mmHg) followed by 5 min of reperfusion. The control group (n = 20) underwent a sham protocol (4 × 5 min of bilateral thigh cuff inflation to 20 mmHg). Thereafter, participants ascended to 3,450 m by train over 2 h and stayed there for 48 h. AMS was evaluated by the Lake Louise score (LLS) and the AMS-C score. Systolic pulmonary artery pressure (SPAP) was assessed by transthoracic Doppler echocardiography. RIPC had no effect on the overall incidence (RIPC: 35%, control: 35%, P = 1.0) and severity (RIPC vs. CONTROL P = 0.496 for LLS; P = 0.320 for AMS-C score) of AMS. RIPC also had no significant effect on SPAP [maximum after 10 h at high altitude; RIPC: 33 (SD 8) mmHg; controls: 37 (SD 7) mmHg; P = 0.19]. This study indicates that RIPC, performed immediately before passive ascent to 3,450 m, does not attenuate AMS and the magnitude of high-altitude pulmonary hypertension.NEW & NOTEWORTHY Remote ischemic preconditioning (RIPC) has been reported to improve neurologic and pulmonary outcome following an acute ischemic or hypoxic insult, yet the effect of RIPC for protecting from high-altitude diseases remains to be determined. The present study shows that RIPC, performed immediately before passive ascent to 3,450 m, does not attenuate acute mountain sickness and the degree of high-altitude pulmonary hypertension. Therefore, RIPC cannot be recommended for prevention of high-altitude diseases.

The objective of this paper is to understand the influence of talent management practices on employee engagement in GLCs. The respondents for the study are drawn from GLCs employees in Malaysia. The study uses statistical analysis to generate result. The results allow researchers to present the data acquired in a structured and accurate manner.
Functional studies on the role of reactive oxygen intermediates in the resistance of barley against powdery mildew

The role of reactive oxygen intermediate (ROI) accumulation in resistance and susceptibility of plants to parasitic fungi is still little understood. We examined the spatial and temporal occurrence of different ROIs in barley after inoculation with the biotrophic fungus Blumeria graminis f.sp. hordei (Bgh, barley powdery mildew fungus). Using histochemical analyses, we collected correlative data indicating that H2O2 and O2 •– play different roles in background penetration resistance to Bgh. To study the role of O2 •– in detail, we isolated barley cDNAs encoding a NADPH oxidase GP91PHOX homologue and a RACB homologue, which may be involved in NADPH oxidase activation. Interestingly, transient silencing of RACB or GP91PHOX via sequence-specific RNA interference enhanced penetration resistance of barley to Bgh. Together, data reveal rather a negative than a positive role of superoxide generation in background resistance of barley to Bgh.
Mining of Social Networks from Classic Books and Visualization 1

While modern online social networks offer unprecedented amount of data and opportunities for mining, we acknowledge that other forms of social networks have been around throughout human history. In particular, we recognize the classic books as valuable sources for the analysis of interpersonal interactions as they have had positive influence on human mind and continue to enlighten the human race. In this paper, we propose a formal framework for the mining of interpersonal interactions from classic books. Our approach employs a heuristic over a traditional named-entity recognition for extracting people names. We demonstrate the effectiveness of our approach by presenting the encouraging result from a network analysis conducted over the persons appearing in the book of Genesis. The result aids the understanding of the persons featured in the book and their interactions. We also present the merits and challenges of visualization techniques pertaining to our work.

Energy cost of ingesting and excreting indigestible material in growing pigs is minimal

The nutritive value of pig feed ingredients is generally derived from the digestible nu- trient supply, while little consideration is given to the impact of indigestible material on nutrient utilization. An experiment was conducted to determine heat production (HP) associated with inges- tion and excretion of indigestible material in growing pigs. Five pairs of littermate barrows were assigned to a basal diet (Basal) or to a basal diet mixed with wheat straw in a 4:1 ratio (Straw). The pigs were housed individually in metabolism crates and adjusted to feeding regimes for at least 10 d prior to measuring components of HP using indirect calorimetry. The dynamics of HP was recorded for 5 d during the fed state and during a subsequent 24 h fast. Feeding behavior, physical activity of the animals and N-balance were monitored to associate HP with feeding (HPfeed), activity and energy retention. Mean body weight (BW) of the pigs was similar (62.1 kg) for both diets. Dry matter intake (1783 vs. 2207 g·d −1 , SE 9) and fecal DM excretion (200 vs. 588 g·d −1 , SE 12) were higher (P 0.10) between treatments: total HP (1374 vs. 1355; SE 14), fasting HP (762 vs. 747; SE 6), activity HP (150 vs. 164; SE 15), HPfeed (452 vs. 444; SE 7), and energy retention (961 vs. 983, SE 10). The overall energy cost of ingesting and excreting indigestible material in growing pigs appears minimal and could not be identified in this experiment.
UDK 619:636.5.084.524 EGG YOLK LIPID MODIFICATIONS BY FAT SUPPLEMENTED DIETS OF LAYING HENS

The aim of this study was to investigate the possibility to modificate the total lipid and cholesterol level, as well as fatty acid composition of egg yolks, by supplementing diets of laying hens with different fats. The trial was conducted in two six week experiments. Experiment I was conducted on 180 Isa Brown hens assigned to two age categories: 36 months old (O), and 27 weeks of age young (Y) hens. Both age categories were divided into three groups: control groups fed a diet I with no supplemented fat (OC and YC); experimental groups fed a diet II supplemented with 3.2% of palm oil (OP and YP) and experimental groups fed a diet III supplemented with 2.5% of lard (OL and YL). In Experiment II 45 Lohman Brown hens of 56 weeks of age were randomly assigned into three groups of 15 birds each and were fed with three experimental diets supplemented with either 3% fish oil (group FO), 3% palm olein (group PO) or with 3% lard (group L). The results of our trial support the thesis of constant cholesterol content in egg yolk, that was accepted by the majority of researchers, although it was possible to affect the levels only in some conditions, as for example by the age of hens in Experiment I, or by feeding Lohman Brown hens with 3% of supplemented lard in Experiment II. However, the experiment proved the possibility of altering egg yolk fatty acid composition, this being a trend in actual investigations of egg yolk cholesterogenic modification.
Culture and the Assessment of Creativitymore

Laboratory studies of culture and creativity typically rely upon measures of divergent thinking while studies of creativity in organizational settings explicitly define creativity and use subject matter experts as assessors to account for the influence of culture on the assessment of creativity. Yet, little is known about what specific characteristics of a creative idea are considered when creativity is assessed by communities of experts (the field) in different spheres of creative activities (domain). In this article, we review, conceptually analyse, and illustrate using original interview data the influence of culture on the assessment of two commonly examined dimensions of overall creativity, novelty, and usefulness. Using the context of expatriates, we propose a framework, along with propositions, that integrates cultural experience, creativity criteria, and assessor perspectives on creativity assessment. Finally, we discuss ways in which a focus upon the processes underlying creativity assessments could help advance research on culture and creativity.
A Parametric Approach To Simulating Use-Patterns in Buildings - The Case Of Movement

We describe one of the three core use-pattern building blocks of a parametric approach to simulating use-patterns in buildings. Use-patterns are modeled as events which use specified descriptions of spaces, actors and activities which constitute them. The simulation system relies on three fundamental patterns of use move, meet and do. The move pattern is considered in detail in this paper with specific reference to what we term the partial knowledge issue. Modeling decision making about how to move through the space (what path to take) depends on modeling the actor's partial access to knowledge. Visibility is used as an example of partial knowledge. The parametric approach described in the paper enables the clear separation of syntactical and semantic conditions which inform decisions and the coordination of decisions made by agents in a simulation of use-patterns. This approach contributes to extending the analytical capability of Building Information Models from the point of view of evaluating how a proposed building design may be used, given complex, interrelated patterns of use.
FORM FINDING FOR 3 D PRINTED PEDESTRIAN BRIDGES

Due to the highly interrelation between architecture and engineering involved in the early design stage of 3D printing, form-finding is the critical step in the large-scale 3D printing projects. This paper focused on the research of form-finding applied in large-scale 3D printed structures, specifically, in the design of two pedestrian bridges. A three-step form finding approach was introduced in this paper. Multiple numerical methods were involved in the approach to find an optimal solution for both aesthetics and structural design for two 3D printed pedestrian bridges. The application of the three steps of form-finding, which take consideration of material properties, site limitations, applied loads etc., to the design of the large-scale 3D printed bridges were discussed in details in this paper. The approach of form-finding in an early designing stage disused in this paper helps to understand the combination of architecture and structure engineering.
Identifying and Estimating Technical Debt for Service Composition in SaaS Cloud

A composite service in multi-tenant SaaS cloud would inevitably operate under dynamic changes on the workload from the tenants, and thus it is not uncommon for the composition to encounter under-utilization and over-utilization on the component services. However, both of those cases could be good or bad: the former implies that although there is under-utilization, the pay-off afterwards are more significant; the latter, in contrast, refers to the over-utilization that leads to trivial pay-off, or nothing at all. Such a notion perfectly matches with the Technical Debt (TD) metaphor in Software Engineering. As a result, it is necessary to identify the root causes of the debts and where the debt can be manifested in the service composition, which, in turn, would offer great helps on the decision making process of service composition. In this paper, we propose a novel approach for identifying the technical debt in service composition under SaaS cloud. The approach combines time series forecasting and a newly proposed technical debt model to estimate the future debt and utility in the service composition. Through a real world case study, we demonstrate that our approach can successfully identify both the good and bad debts, while producing satisfactory accuracy on estimating the technical debt in the service composition under SaaS cloud.
ow to improve pupils ’ literacy ? A cost-effectiveness analysis of a rench educational project

The Action Lecture program is an innovative teaching method run in some nursery and primary schools in Paris and designed to improve pupils’ literacy. We report the results of an evaluation of this program. We describe the experimental protocol that was built to estimate the program’s impact on several types of indicators. Data were processed following a Differences-in-Differences (DID) method. Then we use the estimation of the impact on academic achievement to conduct a cost-effectiveness analysis and take a reduction of the class size program as a benchmark. The results are positive for the Action Lecture program. 20
alladium nanogap-based H 2 sensors on a patterned elastomeric ubstrate using nanoimprint lithography

Here we report a new nanogap formation manner at edges of a palladium (Pd) thin film on highly patterned arrays of an elastomeric PDMS substrate fabricated nanoimprint lithography (NIL) by absorption/desorption cycles of H2 for use in the detection of hydrogen (H2) gas. A 10-nm-thick Pd layer was deposited on the patterned PDMS substrate using an ultra-high vacuum DC magnetron sputtering system. The Pd nanogaps (∼100 nm (W)) formed on the edges of the grating structure by expansion and
The use of sigmoid pH gradients in free‐flow isoelectric focusing of human endothelial cell proteins

Prefractionation of proteins enhances the resolution of proteome analysis of whole cells. Free‐flow electrophoresis (FFE) provides a useful step in various prefractionation protocols, since matrix‐free isoelectric focusing (FF‐IEF) performed in this machine enables the enrichment of large, easily absorbable, sensitive proteins. The impact of the FFE on the success of a proteome analysis depends on the quality of the FF‐IEF separation procedure. Therefore, attempts are continuously being made to improve FF‐IEF. Here, we applied sigmoid pH gradients to the prefractionation of endothelial cell proteins. Small steps of pH incline between neighboring FFE fractions were established in pH ranges, in which the proteins of interest have their pIs. With the help of this advanced technology, we separated vimentin and cytoplasmic actin as well as triosephosphate isomerase and glyceraldehyde phosphate dehydrogenase preparatively, and found a pI of 5.9 ± 0.2 for nonmuscle myosin.
Potential Applications of Nanofiltration Membranes in Copper – Cobalt Processing

Copper–cobalt extraction is a reagent-intensive process resulting in acid consumption greatly contributing towards production costs, which in the current market conditions curtail profitability. Nanofiltration (NF) membranes have become an attractive approach in the mining and minerals industry for product concentration and reagent recovery based on the ability of the membrane to separate monovalent ions from divalent ions. NF membranes can selectively separate acids from metals and salts allowing acid to be recycled as well as the concentration and purification of product streams. Membrane technology in the field of copper–cobalt processing focusses on the concentration of Cu2+ and Co2+ in the pregnant leach solution, recovery of acid from waste streams to neutralization, recovery of valuable metals from waste ponds and process water recovery. This paper aims to provide insight into the potential applications of NF membranes in copper–cobalt processing circuits as well as a brief overview of the effects of process conditions on membrane performance and process development.
