Emotional dysfunctions in neurodegenerative diseases
Authors: Löffler Leonie A.K. , Radke Sina , Morawetz Carmen , Derntl Birgit 
Published: May 2015

ABSTRACTNeurodegenerative diseases are characterized primarily by motor signs but are also accompanied by emotional disturbances. Because of the limited knowledge about these dysfunctions, this Review provides an overview of emotional competencies in Huntington's disease (HD), Parkinson's disease (PD), and multiple sclerosis (MS), with a focus on emotion recognition, emotion regulation, and depression. Most studies indicate facial emotion recognition deficits in HD and PD, whereas data for MS are inconsistent. On a neural level, dysfunctions of amygdala and striatum, among others, have been linked to these impairments. These dysfunctions also tap brain regions that are part of the emotion regulation network, suggesting problems in this competency, too. Research points to dysfunctional emotion regulation in MS, whereas findings for PD and HD are missing. The high prevalence of depression in all three disorders emphasizes the need for effective therapies. Research on emotional disturbances might improve treatment, thereby increasing patients' and caregivers' well‐being. J. Comp. Neurol. 524:1727–1743, 2016. © 2015 Wiley Periodicals, Inc.
A universally composable secure grouping‐proof protocol for RFID tags
Authors: Yuan Bianqing , Liu Jiqiang 
Published: May 2015

SummaryA grouping‐proof protocol is to generate a proof that a group of tags have been scanned simultaneously in the range of a reader. Security and efficiency become the core issues when designing a grouping‐proof protocol. In this paper, we first describe the deployment model, adversary model, and security requirements of a grouping‐proof protocol. Then, we propose an offline reading order‐independent grouping‐proof protocol. To demonstrate security of our scheme, we present an ideal grouping‐proof functionality in the universally composable framework. Subsequently, we prove that the proposed protocol realizes the defined ideal functionality. Compared with the existing grouping‐proof protocols, our scheme satisfies the privacy and security requirements of a grouping‐proof protocol including tag/reader anonymity, tag/reader location privacy, mutual authorized access, anti‐active attack, anti‐replay attack, concurrent security, and so on. Meanwhile, our scheme has desirable performance. It conforms to the computational constraints of low‐cost passive radio frequency identification tags, which makes it suitable for large‐scale application. Copyright © 2015 John Wiley & Sons, Ltd.
Probabilistic response‐time analysis for real‐time systems in body area sensor networks
Authors: Ren Jiankang , Wu Guowei , Li Xinjiao , Pirozmand Poria , Obaidat Mohammad S. 
Published: May 2015

SummaryAdvances in real‐time system and wireless communication have led to the deployment of body area sensor networks (BASNs) for effective real‐time healthcare applications. Real‐time systems in BASNs tend increasingly to be probabilistic and mixed critical to meet stringent requirements on space, weight, and power consumption. Response‐time analysis is an important and challenging task for BASNs to provide some critical services. In this paper, we propose a request‐based compositional probabilistic response‐time analysis framework for probabilistic real‐time task models with fixed‐priority preemptive scheduling in BASNs. In this method, each probabilistic real‐time task is abstracted as a probabilistic request function. Rough response‐time distribution is computed first based on the cumulative request distribution and then exact response‐time distribution is obtained by refinement based on the request increase distribution. Our strategy can effectively improve performance by reducing repetitive computational overhead for the probabilistic response‐time analysis of all tasks in the system. Our evaluation demonstrates that our proposed method significantly outperforms the existing probabilistic response‐time analysis algorithm in terms of analysis duration.

Partitioned scheduling for sphere decoding with runtime constraints for practical MIMO communication systems
Authors: Kim T. H. , Kim J. W. 
Published: May 2015

SummaryThis paper presents an effective scheduling scheme for sphere decoding (SD) with runtime constraints, targeting the practical multiple‐input multiple‐output (MIMO) communication systems where neither the interleaving scheme nor its block size cannot be designed freely. The proposed scheme imposes runtime constraints on SD to distribute the errors due to the early termination of SD. Because the distributed errors may be corrected effectively by forward error correction, the error‐rate performance can be improved; experimental results show that the performance improvement is approximately 2dB in terms of the signal‐to‐noise ratio to achieve a bit‐error rate of 10−4 in 4 × 4 16‐QAM MIMO systems.

Biocuration at the Saccharomyces genome database
Authors: Skrzypek Marek S. , Nash Robert S. 
Published: May 2015

SummarySaccharomyces Genome Database is an online resource dedicated to managing information about the biology and genetics of the model organism, yeast (Saccharomyces cerevisiae). This information is derived primarily from scientific publications through a process of human curation that involves manual extraction of data and their organization into a comprehensive system of knowledge. This system provides a foundation for further analysis of experimental data coming from research on yeast as well as other organisms. In this review we will demonstrate how biocuration and biocurators add a key component, the biological context, to our understanding of how genes, proteins, genomes and cells function and interact. We will explain the role biocurators play in sifting through the wealth of biological data to incorporate and connect key information. We will also discuss the many ways we assist researchers with their various research needs. We hope to convince the reader that manual curation is vital in converting the flood of data into organized and interconnected knowledge, and that biocurators play an essential role in the integration of scientific information into a coherent model of the cell. genesis 53:450–457, 2015. © 2015 Wiley Periodicals, Inc.
Weight suppression predicts total weight gain and rate of weight gain in outpatients with anorexia nervosa
Authors: Carter Frances A. , Boden Joseph M. , Jordan Jennifer , McIntosh Virginia V.W. , Bulik Cynthia M. , Joyce Peter R. 
Published: May 2015

ABSTRACTObjectiveThe present study sought to replicate the finding of Wildes and Marcus, Behav Res Ther, 50, 266–274, 2012 that higher levels of weight suppression at pretreatment predict greater total weight gain, faster rate of weight gain, and bulimic symptoms amongst patients admitted with anorexia nervosa.MethodParticipants were 56 women with anorexia nervosa diagnosed by using strict or lenient weight criteria, who were participating in a randomized controlled psychotherapy trial (McIntosh et al., Am J Psychiatry, 162, 741–747, 2005). Thirty‐five women completed outpatient treatment and post‐treatment assessment. Weight suppression was the discrepancy between highest lifetime weight at adult height and weight at pretreatment assessment. Outcome variables were total weight gain, rate of weight gain, and bulimic symptoms in the month prior to post‐treatment assessment [assessed using the Eating Disorders Examination (Fairburn et al., Binge‐Eating: Nature, Assessment and Treatment. New York: Guilford, 1993)].ResultsWeight suppression was positively associated with total weight gain and rate of weight gain over treatment. Regression models showed that this association could not be explained by covariates (age at onset of anorexia nervosa and treatment modality). Weight suppression was not significantly associated with bulimic symptoms in the month prior to post‐treatment assessment, regardless of whether bulimic symptoms were examined as continuous or dichotomous variables.DiscussionThe present study reinforces the previous finding that weight suppression predicts total weight gain and rate of weight gain amongst patients being treated for anorexia nervosa. Methodological issues may explain the failure of the present study to find that weight suppression predicts bulimic symptoms. Weight suppression at pretreatment for anorexia nervosa should be assessed routinely and may inform treatment planning. © 2015 Wiley Periodicals, Inc. (Int J Eat Disord 2015; 48:912–918).
Naturally occurring protein–polysaccharide complexes from linseed (Linum usitatissimum) as bioemulsifiers

Published: May 2015

The use of proteins, polysaccharides, and their mixtures as bioemulsifiers is becoming increasingly important due to their high versatility and environmental acceptability. In this study, three different fractions mainly composed of protein and polysaccharides, extracted from linseed were evaluated as bioemulsifiers. The three fractions showed the same functional groups, and the amino acid profile revealed the presence of apolar amino acids which are important for forming emulsions. All negatively charged fractions were affected at pH values below 6 and above 100 mM NaCl, confirming their ionic character. Fraction 3 formed oil‐in‐water emulsion (O/W) and its estimated hydrophilic–lipophilic balance (HLB) value was 10–13. A phase diagram was used to produce a long‐term stable O/W emulsion using Fraction 3 as a bioemulsifier. The emulsion containing linseed oil Fraction 3 and water of 5:5:90% w/w exhibited 100% stability under a wide pH range (5–11), ionic strengths (0–500 mM NaCl), and temperatures (4–70°C). Based on these results, Fraction 3, composed of 47.20% w/w protein and 37.88% w/w polysaccharide from linseed, can be considered a potential natural emulsifier for improving stability of O/W emulsions in the face of environmental stresses.Practical applications: The increasing customer demand for natural over synthetic ingredients and the rapid growth of functional foods requiring “green” additives represents an opportunity for bioemulsifiers extracted from natural resources. Linseed and the by‐products after oil extraction have great potential as a source of ingredients and bioactive molecules for food applications. In this work, the capability of protein/polysaccharide fractions from linseed as bioemulsifiers to form highly stable O/W emulsions containing omega‐3 rich oil was demonstrated. The designed emulsion proved to be stable at acidic pH and salt concentrations found in many food products. Moreover, thermal stability exhibited by this emulsion could also be an important characteristic for its use in food products.Phase diagram illustrating the emulsion area with linseed oil‐Fraction 3‐water and a microscopic image in the zone of 100% emulsion (black shaded area).

Published: May 2015

The degradation occurring in soybean oil, camellia oil, and binary blends at five ratios during deep frying of french fries at 180°C for five consecutive days was monitored. The decrease in polyunsaturated and increase in saturated fatty acids during the frying operation was more prominent in soybean oil as compared to the camellia oil and blended oils. Among the frying periods, camellia oil, blend (60:40) and blend (50:50) after frying did not change significantly in the overall fatty acid composition. In addition, results of physicochemical properties of the frying media, namely the free fatty acid, peroxide value, p‐anisidine value, total polar components, and color, indicate that camellia oil has the least degradation, while soybean oil has the highest. What is more, these results reveal that increase in oxidative stability is correlated with the increase in camellia oil levels, due to the high content of phenolic compounds and monounsaturated fatty acid. Therefore, the present study clearly indicated that partial replacement of soybean oil with camellia oil can significantly improve frying stability for deep frying of french fries.Practical applications: The results are useful for home cooking, restaurants, or fast foods sellers providing them with newly developed frying stability oils, camellia oil, and camellia/soybean blended oils for deep frying of french fries. Furthermore, discarding time was provided for soybean oil, camellia oil, and their blends when used as media for french fries frying, this suggestion allows preparing safe fried foods for consumers.Total polar compounds of oils during 5 days of usage for deep frying of french fries.
