Investigation of tearing mechanisms of woven textile
Authors: Triki Ennouri , Nguyen‐Tri Phuong , Boukehili Hychem , Vu‐Khanh Toan 
Published: August 2012

AbstractTearing resistance is an important parameter for evaluating the reliability of textile structures, especially in the case of protective materials. In order to better understand the individual contribution of the different mechanisms involved in the tearing process, a study of the relation between the fabric and yarn properties characterizing these mechanisms and the tearing energy has been carried out. For that purpose, polyester fabrics with two types of weave patterns and various values of filling yarn density and linear density were characterized in terms of tongue tear energy, yarn and fabric modulus, breaking force and elongation at break, yarn slippage, and yarn jamming. Data for all tested fabrics relied on a unique master curve when the tearing energy was expressed as a function of the transverse yarn slippage force. This demonstrates the strong contribution of transverse yarn slippage to the tearing process, a mechanism which has generally been overlooked in previous works on tearing. Relationships between the tearing energy and the other properties characteristics of the mechanisms involved in tearing of woven textiles were also observed. These results build the path toward the development of models for the tearing energy of textile structures. POLYM. COMPOS., 2012. © 2012 Society of Plastics Engineers
Empathy, emotional contagion, and rapid facial reactions to angry and happy facial expressions
Authors: Dimberg Ulf , Thunberg Monika 
Published: August 2012

AbstractThe aim was to explore whether emotional empathy is related to the capacity to react with rapid facial reactions to facial expressions of emotion, and if emotional empathy is related to the ability to experience a similar emotion as expressed by another person. People high or low in emotional empathy were exposed to pictures of happy and angry faces while their facial electromyography from the zygomaticus major and corrugator supercilii muscle regions was detected. High empathy participants rapidly reacted with larger zygomatic muscle activity to happy as compared with angry faces as early as after 500 ms after stimulus onset, and with larger corrugator muscle activity to angry than to happy faces after 500 ms. Accordingly, this group also reacted with a corresponding experience of emotion. The low empathy participants, in contrast, did not differentiate between the happy and angry stimuli with either facial muscles or in their self experience of emotion. The findings are related to the facial feedback hypothesis and the results are interpreted as support for the hypothesis that rapid and automatically evoked facial mimicry may be one important mechanism for emotional and empathic contagion to occur.

Published: August 2012

AbstractAccumulating evidence suggests that stress‐dose corticosteroids impair fear memory in animals and humans. Corticosteroid treatment after critical illness is seen as a potential psychotropic medication by which to prevent posttraumatic stress disorder. However, individual difference in the responsiveness to stress (i.e., stress reactivity) is a factor that modulates the efficacy of corticosteroids. To understand the contribution of fear reactivity to the effect of post‐stress corticosterone, male Sprague‐Dawley rats were subjected to classical tone‐cued fear conditioning and separated into high and low reactivity (HR and LR, respectively) responder groups based on their levels of freezing during conditioning. The HR rats showed significantly higher fear responses than the LR rats during conditioning as assessed by freezing behavior. At two intervals, 30 min and 48 hr later, the HR rats still displayed more pronounced conditioned responses to cued stimuli compared with the LR rats. Moreover, in contrast to the LR rats, the enhanced fear response in the HR rats was difficult to attenuate by post‐training high‐dose corticosterone. These results suggest that fear reactivity results in stronger fear memory, and that it is difficult to disrupt this strong fear memory in the HR phenotype using monotherapy. However, the strong fear memory in the HR rats was impaired by concurrent intramedial prefrontal cortex infusion of a high dose of the dopamine D1 receptor antagonist SCH 23390 and systemic administration of corticosterone. SCH 23390 and corticosterone alone did not decrease freezing levels in the HR rats. The fear impairment induced by SCH 23390 combined with corticosterone was not attributable to the effect of these drugs on locomotor activity. This effect was not found with administration of the D2 antagonist eticlopride combined with corticosterone. Our findings demonstrate that the conditioned fear memory in individuals with high stress reactivity is difficult to disrupt using monotherapy, but that combined pharmacotherapy may be useful for treating intervention‐resistant fear.

Published: August 2012

AbstractBackgroundFor many patients with lung cancer, disease progression occurs without notice or with vague symptoms, and unfortunately, most treatments are not curative. Given this unpredictability, we hypothesized the following: (1) poorer psychological adjustment (specifically, more depressive symptoms, higher perceptions of stress, and poorer emotional well‐being) would be associated with higher intolerance for uncertainty, higher perceived illness‐related ambiguity, and their interaction; and (2) greater avoidance would mediate associations between higher intolerance of uncertainty and poorer psychological adjustment.MethodsParticipants (N = 49) diagnosed with lung cancer at least 6 months prior to enrollment completed the Center for Epidemiologic Studies – Depression Scale, the Functional Assessment of Cancer Therapy – Lung Emotional Well‐being subscale, the Perceived Stress scale, the Intolerance of Uncertainty scale, the Mishel Uncertainty in Illness Scale Ambiguity subscale, the Impact of Event – Revised Avoidance subscale, and the Short‐scale Eysenck Personality Questionnaire – Revised Neuroticism subscale. Mean age was 64.2 years (standard deviation [SD] = 11.0), mean years of education was 15.6 (SD = 3.1), and 71.4% were female. Hypotheses were tested with regression analyses, adjusted for neuroticism.ResultsHigher perceptions of stress and poorer emotional well‐being were associated with higher levels of intolerance of uncertainty and higher perceived illness‐related ambiguity. Non‐somatic depressive symptoms were associated with higher levels of intolerance of uncertainty. Avoidance was found to mediate relations of intolerance of uncertainty with non‐somatic depressive symptoms and emotional well‐being only.ConclusionsFindings suggest that interventions to address avoidance and intolerance of uncertainty in individuals with lung cancer may help improve psychological adjustment.

Authors: Robbins Megan L. , Mehl Matthias R. , Smith Hillary L. , Weihs Karen L. 
Published: August 2012

AbstractBackgroundThis study examined how language reflective of emotional and social processes during a cancer‐related discussion relates to patient, couple, and family adjustment after breast cancer. It investigated whether emotional expression or relational focus, manifested in language use, indicates healthy family coping following breast cancer.MethodsFamily members each completed measures of adjustment (Family Environment Scale, Dyadic Adjustment Scale, and patient Profile of Mood States) and engaged in a 15‐min family discussion about how they have coped with breast cancer. Transcripts from the discussion were submitted to a text‐analysis software program to obtain frequency of positive and negative emotion words, and personal pronouns spoken by each family member. The relationship between self‐reports of adjustment and frequency of language use during the family discussion was analyzed with regression models.ResultsPartners' positive emotion words were indicative of better family adjustment, patients' negative emotion words indicated greater family conflict, and sons' and daughters' anger words indicated poorer adjustment, whereas their anxiety words indicated better family adjustment. Partner we‐talk was related to better dyadic adjustment, and couples' ‘you’ was somewhat related to worse adjustment at all levels.ConclusionsImportant information about how a family copes with breast cancer can be obtained by attending to families' emotional and relational language. This study suggests that clinicians and members of families' support networks can gauge how well a family has adapted after the breast cancer experience by attending to the type of words that each family member uses to describe how they coped with breast cancer.

Published: August 2012

AbstractVacancy‐interstitial‐oxygen‐carbon (VIOC) complexes induced by electron irradiation in ultra‐low and low carbon content (well below and around 1015/cm3) CZ silicon crystals were examined by highly sensitive infrared (IR) absorption spectroscopy at RT. Absorption lines of peak absorbance down to 5x10‐6 were successfully delineated. Dose dependence and annealing temperature dependence were systematically investigated. Both major and minor groups were detected. Increase, saturation and decrease for the dose increase is mainly due to the chain reaction. Order estimate of complex concentration was performed. In addition to the established advantage of IR such as wide applicability to all complexes, reliable assignment and insensitivity to coexisting defects, high sensitivity down to 5x1012/cm3 was established. The problem of measuring carbon substitutional (Cs) concentration was discussed and reduction of [Cs] in the reference material by irradiation is demonstrated. These techniques will provide reliable measurement of oxygen, and nitrogen also and tool for analysis of the infrared defect dynamics in growing silicon crystals. (© 2012 WILEY‐VCH Verlag GmbH & Co.

A re‐examination of the interstitial Ti levels in Si
Authors: Kolkovsky Vladimir , Scheffler Leopold , Weber Joerg 
Published: August 2012

AbstractUsing high‐resolution Laplace DLTS studies we demonstrate that three Ti‐related levels (E40, E150 and H180) previously assigned to the different charge states of the interstitial Ti belong to different Ti defects. The enhancement of the emission rates of E40 and H180 as a function of the electric field (Poole‐Frenkel effect) shows that these defects are charged before they capture a majority carrier in n‐ and p‐type Si, respectively. In contrast to the previous studies we did not observe the Poole‐Frenkel effect for E150. The inconsistence is correlated with the presence of H‐related defects close to E150, which cannot be distinguished by using the conventional DLTS technique. The absence of the Poole‐Frenkel effect for E150 indicates that the defect is an acceptor in n‐type Si. The origin of the defects will be discussed. (© 2012 WILEY‐VCH Verlag GmbH & Co.

Sequential hydrogen dissociation from a charged Pt13H24 cluster modeled by ab initio molecular dynamics
Authors: Meng Qingguo , May P. Stanley , Berry Mary T. , Kilin Dmitri 
Published: August 2012

AbstractPlatinum is one of the most valuable catalysts that have been used in the catalytic fields of hydrogenation, fuel‐cell technologies, and photocatalytic water splitting. In this work, the dissociative chemisorption of hydrogen in a molecular form on a Pt13H24 cluster with cuboctahedral symmetry (Oh), which has one center Pt atom and side 12 Pt atoms (each bonded by two hydrogen), is investigated by using first‐principles density functional theory calculation. After computing geometry optimization on the Pt13H24 cluster, the equilibrium distances of PtPt and PtH are inspected. Two nonequilibrium modifications, for example, addition of electrons and heat treatment were applied on the cluster, with the aim to simulate the experimental reaction of hydrogen on the Pt13 H24 cluster. An ab initio molecular dynamics (MD) is simulated after the cluster is charged and heat treated at high temperature to compute the trajectory for the positions of all the atoms. The computation results reveal that H2 desorption is observed during the MD simulation, and higher temperature is beneficial to the H2 desorption. An elementary hydrogen evolution mechanism on the charged Pt cluster can be established as 2Hads+ + 2e− + Ptads→ [PtadsHadsHads] → H2↑ + Pt. A rate (fs−1) of hydrogen desorption from different cluster models is determined, together with the hydrogen dissociative activation energy as a function of total charge. © 2012 Wiley Periodicals, Inc.
Analysis and control of switched linear systems via modified Lyapunov–Metzler inequalities
Authors: Duan Chang , Wu Fen 
Published: August 2012

SUMMARYThis paper addresses analysis and switching control problems of continuous/discrete‐time switched linear systems. A particular class of matrix inequalities, the so‐called Lyapunov–Metzler inequalities, will be modified to provide conditions for stability analysis and output feedback control synthesis under a relaxed min‐switching logic. The switching rule combined with switching output feedback controllers will be designed to stabilize the switched system and satisfy a prespecified gain performance. The proposed analysis and switching control approach could refrain frequent switches commonly observed in min‐switching based designs. The effectiveness of the proposed approach will be illustrated through numerical examples. Copyright © 2012 John Wiley & Sons, Ltd.
Self‐tuning minimum variance control of linear systems followed by saturation nonlinearities in a noisy frame
Authors: Pupeikis Rimantas 
Published: August 2012

SUMMARYThe aim of the present paper was to increase the efficiency of self‐tuning minimum variance (MV) control of linear systems followed by the so‐called hard nonlinearities. To this end, an approach based on reordering of observations to be processed for the reconstruction of an unmeasurable internal intermediate signal, which acts between a linear dynamic time‐invariant (LTI) system and a static nonlinear block of the closed loop Wiener system with a saturation nonlinearity in an output, has been developed. The technique based on the ordinary least squares and on data partition is used for the internal signal extraction. The results of numerical simulation, identification, and self‐tuning MV control as well as generalized MV control of the second‐order discrete‐time closed loop LTI system with the saturation nonlinearity are given by the computer.

FTDA: outlier detection‐based fault‐tolerant data aggregation for wireless sensor networks
Authors: Ozdemir Suat , Xiao Yang 
Published: August 2012

ABSTRACTData aggregation protocols are essential for wireless sensor networks to prolong network lifetime by reducing energy consumption of sensor nodes. For mission‐critical wireless sensor networks, however, not only the energy consumption of sensor nodes but also the correctness of the data aggregation results is critical. As wireless sensor networks are usually deployed in harsh and hostile environments, malfunctioning and/or compromised sensor nodes negatively affect the correctness of the data aggregation results. This paper presents a fault‐tolerant data aggregation scheme that eliminates the false data sent by malfunctioning and/or compromised sensor nodes. To conserve energy while eliminating false data, an in‐network outlier detection technique that is based on locality sensitive hashing scheme is used. The simulation results show that the proposed scheme is able to reduce the number of false data transmissions, thereby increasing the data aggregation accuracy. Moreover, it is also observed that the proposed scheme reduces the overall data transmission in the network. Copyright © 2012 John Wiley & Sons, Ltd.
Using particle swarm optimization in fuzzy association rules‐based feature selection and fuzzy ARTMAP‐based attack recognition
Authors: Sheikhan Mansour , Sharifi Rad Maryam 
Published: August 2012

ABSTRACTFeature selection is a classic research topic in data mining, and it has attracted much interest in many fields such as network security. In addition, data mining approaches such as fuzzy association rule mining (FARM) can improve the performance of intrusion detection systems. In this study, a FARM‐based feature selector is proposed in order to reduce the dimension of input features to the misuse detector. Furthermore, a fuzzy ARTMAP neural network is used as the classifier. The accuracy of the proposed approach depends strongly on the precision of the parameters of FARM‐based feature selector module and fuzzy ARTMAP neural classifier. Particle swarm optimization (PSO) algorithm is incorporated into the proposed method to determine optimum values of parameters. In this way, the performance of PSO algorithm is compared with genetic algorithm (GA), as well. Experimental results indicate that PSO outperforms GA both in population size and number of evolutions and can converge faster. This is very important for enhancing the mining performance in large datasets such as intrusion detection datasets. When compared with some other machine learning methods, the proposed system indicates better performance in terms of detection rate, false alarm rate, and cost per example.

A secure IPv6 address configuration scheme for a MANET
Authors: Wang Xiaonan , Mu Yi 
Published: August 2012

ABSTRACTWe propose a secure Internet Protocol version 6 (IPv6) address configuration scheme for a Mobile Ad Hoc Network. The scheme presents the architecture for a Mobile Ad Hoc Network and the hierarchical IPv6 address structure. In the architecture, a new node can acquire a unique IPv6 address from a proxy node within one‐hop scope without performing a duplicate address detection process, and the IP addresses occupied by failed nodes can be recovered automatically for reuse. On the basis of the hierarchical IPv6 address structure, each proxy node can acquire a unique address scope for assignment and assign a unique IP address for new nodes, so the address configuration task is distributed around proxy nodes. In addition, the transmission scope of the control packets for address configuration is controlled within one‐hop scope, so the address configuration cost is reduced, and the delay is shortened. The security of the proposed address configuration scheme is achieved through authentication. The paper analyzes the performance parameters of the proposed scheme and the existing schemes, and the analytical results show that the address configuration cost of the proposed scheme is lower and the delay is shorter.

Children's Acceptance of Others with Disability: The Influence of a Disability‐Simulation Program
Authors: Hurst Christina , Corning Ken , Ferrante Richard 
Published: August 2012

AbstractElementary school is a transitional and impressionable period for any child. In inclusive classroom settings, children with disabilities may experience the challenges of acceptance and integration into peer relationships. The experience of children with disabilities in such classrooms can be positive if their classmates are accepting and open. One way to encourage these attitudes is by increasing awareness through disability‐simulation. This study evaluates an existing school program, whose goal is to increase acceptance of others with disability. We surveyed students to assess the influence of the program. An adapted acceptance scale was distributed to students before and after participation in the program. Our hypothesis was that student acceptance would increase after participating in the program. Additionally, we hypothesized that physical, visual, and auditory disabilities would be easier for students to understand, making acceptance scores for these disabilities higher than those for a learning disability. We report changes in acceptance using group means. Our results reveal that post‐survey responses showed higher acceptance than pre‐survey responses, especially for auditory disabilities. Other significant findings include differences in attitudes between the two schools and differences based on prior experience with someone with a disability. By evaluating the effectiveness of this type of program (whose efficacy has been controversial in the literature), this study can provide teachers, administrators, genetic counselors, and parents with a better idea of how to address children's attitudes towards peers. In our study, the effectiveness of promoting understanding through disability‐simulation has proven its worth to improve children's acceptance.
Phytoplankton species abundance in Lake Kasumigaura (Japan) monitored monthly or biweekly since 1978
Authors: Takamura Noriko , Nakagawa Megumi 
Published: August 2012

AbstractThis data paper reports the abundance of phytoplankton species in monthly or biweekly samples collected from May 1978 through March 2010 at two stations on Lake Kasumigaura, a shallow lake that is the second‐largest lake in Japan. The data set of quantitatively over several decades is unique among the available published data papers concerning lakes or plankton and continues to be freely available. The monitoring has been performed as a component of the Lake Kasumigaura Long‐term Environmental Monitoring program, conducted by the National Institute for Environmental Studies since 1977. The data set details 173 phytoplankton species (or taxa), which can be identified by using an optical microscope and records their abundance. The abundance of each species is expressed in units of volume (μm3) per milliliter of lake water. This approach allows quantitative comparisons among taxa because the cell size of phytoplankton varies by several orders of magnitude among taxa. The phytoplankton data include 39 species (taxa) of Cyanophyta, 67 Chlorophyceae (Chlorophyta), 3 Prasinophyceae (Chlorophyta), 1 Raphidophyceae (Heterokontophyta), 6 Euglenophyceae (Euglenozoa), 4 Dinophyceae (Dinophyta), 38 Bacillariophyceae (Heterokontophyta), 6 Chrysophyceae (Heterokontophyta), 7 Xanthophyceae (Heterokontophyta), 1 Cryptophyceae (Cryptophyta) and 1 Prymnesiophyceae (Haptophyta). The data have been used for ecological and environmental studies and for studies on lake management.
