Realization of an Expandable Search Function for an E-Learning Web Portal

When providing a huge amount of content to users, the search engine is an important part of the platform. On most web sites it is the most important entry point to the data archive. That is why it is an interesting research topic. In this paper we present a solution how it is possible to make the search function expendable by using plug-ins. We show, why this is required in our web application, which is constantly growing through the creation of more searchable meta data. Therefore we show, how our requirements can be fulfilled and discuss the accompanying advantages and disadvantages.
Cell cycle commitment of rat muscle satellite cells

Satellite cells of adult muscle are quiescent myogenic stem cells that can be induced to enter the cell cycle by an extract of crushed muscle (Bischoff, R. 1986. Dev. Biol. 115:140-147). Here, evidence is presented that the extract acts transiently to commit cells to enter the cell cycle. Satellite cells associated with both live and killed rat myofibers in culture were briefly exposed to muscle extract and the increase in cell number was determined at 48 h in vitro, before the onset of fusion. An 8-12-h exposure to extract with killed, but not live, myofibers was sufficient to produce maximum proliferation of satellite cells. Continuous exposure for over 40 h was needed to sustain proliferation of satellite cells on live myofibers. The role of serum factors was also studied. Neither serum nor muscle extract alone was able to induce proliferation of satellite cells. In the presence of muscle extract, however, satellite cell proliferation was directly proportional to the concentration of serum in the medium. These results suggest that mitogens released from crushed muscle produce long-lasting effects that commit quiescent satellite cells to divide, whereas serum factors are needed to maintain progression through the cell cycle. Contact with a viable myofiber modulates the response of satellite cells to growth factors.
Development of the Risk Management Mechanism of an Enterprise Resource Planning System based on Work System Method

This study collects 24 risk-management-relevant research papers published between 2000 and 2010 to elicit significant risk factors and thus develop the risk management mechanism of an enterprise resource planning (ERP) system. The study adopts the grounded theory and conducts an expert questionnaire in order to report its findings on 49 risk factors. Based on the work system method, the identified factors are classified into nine categories and a risk management mechanism is developed thereafter. Finally, to examine the feasibility of the mechanism, two case studies are further investigated. The developed mechanism is found to be a convenient, quick, and proper ERP system risk management tool that can assist enterprises in identifying, analyzing, assessing, and responding to potential risks.
Cumulative Effects of Concussion in High School Athletes

OBJECTIVE A common assumption in sports medicine is that a history of concussion is predictive of a lower threshold for, as well as a worse outcome after, subsequent concussive injury. The current study was conducted to investigate the relationship between concussion history in high school athletes and the on-field presentation of symptoms after subsequent concussion. METHODS One hundred seventy-three athletes who experienced sports-related concussion composed the initial study group. Binary groups were subsequently created on the basis of concussion history. Sixty athletes with no concussion history were compared with 28 athletes with a history of three or more concussions. The groups were compared in terms of the on-field presentation of symptoms after an in-study concussion. Dependent variables included the postinjury presence of loss of consciousness, anterograde amnesia, retrograde amnesia, and confusion. RESULTS Athletes with three or more prior concussions were more likely to experience on-field positive loss of consciousness (&khgr;2 = 8.0, P = 0.005), anterograde amnesia (&khgr;2 = 5.5, P = 0.019), and confusion (&khgr;2 = 5.1, P = 0.024) after a subsequent cerebral concussion. An odds ratio revealed that athletes with a history of three concussions were 9.3 times more likely than athletes with no history of concussion to demonstrate three to four abnormal on-field markers of concussion severity. CONCLUSION This study is the first to suggest a cumulative effect of concussion in high school athletes. A more severe on-field presentation of concussion markers is evidenced in high school athletes with a pronounced history of concussion. This study’s findings highlight the need for more long-term outcome studies in high school athletes who sustain sports-related concussions.
The Role of Antimicrobial Peptides in Preventing Multidrug-Resistant Bacterial Infections and Biofilm Formation

Over the last decade, decreasing effectiveness of conventional antimicrobial-drugs has caused serious problems due to the rapid emergence of multidrug-resistant pathogens. Furthermore, biofilms, which are microbial communities that cause serious chronic infections and dental plaque, form environments that enhance antimicrobial resistance. As a result, there is a continuous search to overcome or control such problems, which has resulted in antimicrobial peptides being considered as an alternative to conventional drugs. Antimicrobial peptides are ancient host defense effector molecules in living organisms. These peptides have been identified in diverse organisms and synthetically developed by using peptidomimic techniques. This review was conducted to demonstrate the mode of action by which antimicrobial peptides combat multidrug-resistant bacteria and prevent biofilm formation and to introduce clinical uses of these compounds for chronic disease, medical devices, and oral health. In addition, combinations of antimicrobial peptides and conventional drugs were considered due to their synergetic effects and low cost for therapeutic treatment.
Vitamin C Protected Human Retinal Pigmented Epithelium from Oxidant Injury Depending on Regulating SIRT1

The purpose was to investigate the protective effects of Vitamin C (Vit C) and the regulatory mechanism between Vit C and sirtuin 1 (SIRT1) in PREs during oxidative stress as Vit C and SIRT1 exerted famous effects as antioxidants. We found that moderate Vit C (100 µM) prevented ARPE-19 cells from damages induced by H2O2, including increasing viability, reducing apoptosis, and attenuating intracellular ROS levels. But lower and higher concentration of Vit C had no effects. Further results indicated that Vit C caused the dysregulation of some stress responses factors (SIRT1, p53 and FOXO3) in ARPE-19 cells response to H2O2. Moreover we found that SIRT1 activator resveratrol (SRV) stimulated significantly the protective effects of moderate Vit C, provided the property of antioxidative stress for the lower and higher concentration of Vit C in ARPE-19 cells as well. Consistently, nicotinamide (NA) relieved the protective functions of moderate Vit C. Interestingly, data also revealed the dysregulation of p53 and FOXO3 was dependent on the regulation of SIRT1 rather than Vit C. Summarily, the protective effect of Vit C against oxidative stress was involved in regulation of SIRT1. It suggested that combined application of Vit C and RSV might be a promising therapeutic method for AMD.
Enhancing application servers with semantics

We report on using semantic technology to enhance application servers. In particular, the conclusion of our analysis is that OWL-S, an emerging effort for semantic webservice descriptions, is a good starting point for supporting many frequent tasks within a concrete application server which facilitates reusing and combining SemanticWeb software modules (e.g. ontology stores, reasoners, etc.). The focus of this paper is on detailing the design of the supporting ontology: (1) identifying the aspects of application servers that benefit from semantic technology and (2) analyzing and extending OWL-S for this purpose.We also report on the integration of this ontology within the server.
The Arabidopsis Epithiospecifier Protein Promotes the Hydrolysis of Glucosinolates to Nitriles and Influences Trichoplusia ni Herbivory Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.010261.

Glucosinolates are anionic thioglucosides that have become one of the most frequently studied groups of defensive metabolites in plants. When tissue damage occurs, the thioglucoside linkage is hydrolyzed by enzymes known as myrosinases, resulting in the formation of a variety of products that are active against herbivores and pathogens. In an effort to learn more about the molecular genetic and biochemical regulation of glucosinolate hydrolysis product formation, we analyzed leaf samples of 122 Arabidopsis ecotypes. A distinct polymorphism was observed with all ecotypes producing primarily isothiocyanates or primarily nitriles. The ecotypes Columbia (Col) and Landsberg erecta (Ler) differed in their hydrolysis products; therefore, the Col × Ler recombinant inbred lines were used for mapping the genes controlling this polymorphism. The major quantitative trait locus (QTL) affecting nitrile versus isothiocyanate formation was found very close to a gene encoding a homolog of a Brassica napus epithiospecifier protein (ESP), which causes the formation of epithionitriles instead of isothiocyanates during glucosinolate hydrolysis in the seeds of certain Brassicaceae. The heterologously expressed Arabidopsis ESP was able to convert glucosinolates both to epithionitriles and to simple nitriles in the presence of myrosinase, and thus it was more versatile than previously described ESPs. The role of ESP in plant defense is uncertain, because the generalist herbivore Trichoplusia ni (the cabbage looper) was found to feed more readily on nitrile-producing than on isothiocyanate-producing Arabidopsis. However, isothiocyanates are frequently used as recognition cues by specialist herbivores, and so the formation of nitriles instead of isothiocyanates may allow Arabidopsis to be less apparent to specialists.

Adolescent Well-being Outcomes of Parental Perceptions of Work: Effects of Family Processes

Dual-earner families are an increasing demographic in our society (U.S. Bureau of Labor Statistics, 2006a, 2006b). Employers, policymakers, and academics have focused their attention on how to best alleviate the negative consequences of work on families, and enhance the benefits that work and family can bring to one another. One aspect of the connection between work and family is the relationship between parental employment and adolescent well-being. This dissertation seeks to identify the relationships between parental perceptions of their job family-friendliness, satisfaction, stress and burnout, and spillover, and adolescent perceptions of parental mood after work, parental acceptance, and adolescent well-being. The current study uses data from a sample of 150 working families with adolescents from the Nurturing Families Study. This investigation examined parents’ perceptions of their jobs and their middle school-aged children’s assessments of parents’ work and family processes as potential mediators or moderators. The relationships were analyzed using regression modeling techniques. Findings determine the extent to which parental employment experiences explain variance in adolescents’ well-being. The most compelling findings from this dissertation suggest that parental assessments of their jobs and adolescent well-being are connected, though not directly. Connections between parent’s jobs and adolescent well-being were seen only in relation to adolescent perceptions of mother’s work and family contexts. Results indicate that adolescent perceptions of their mothers’ level of acceptance moderated the relationship between mothers’ reports of their job family-friendliness and their adolescents’ reports of well-being. For mothers with low job family-friendliness, mother acceptance diminishes the negative association of this workplace characteristic on adolescent well-being. Additionally, when a mother’s job satisfaction is low, adolescent perceptions of her mood after work diminishes the negative association of this workplace characteristic on their well-being more so than when job satisfaction is high. Family practitioners and clinical social workers will be able to use the findings to enhance their clinical work with families with adolescents. The results of the study are also relevant to employers and social workers within organizations. Finally, macro social workers interested in enhancing the well-being of working families and adolescents will be informed by the results of this study.
Emotional tagging of videos by exploring multiple emotions' coexistence

Videos may induce users' mixture emotions. Most present emotional tagging research ignore the phenomena of multiple emotions' coexistence and mutual exclusion. In this paper, we propose a novel emotional tagging approach by exploring multiple emotion's relations. First, several visual and audio features are extracted from videos. Second, support vector machines are used as the classifiers to get the measurements of emotional tags. Then, a Bayesian network is adopted to learn the relationships among emotional tags. After that, the Bayesian network is used to infer the video tags combining the measurements obtained by support vector machines. Experiments on a dataset of 72 affective videos demonstrate the effectiveness of our approach.
Video communication system based on hybrid packetization scheme

For society's rising demand of video communication and monitoring, we propose a design and implementation plan of embedded video communication system based on hybrid packetization scheme. The system can run in the embedded Linux system based on a hybrid packetization scheme suitable for poor network conditions and high-resolution video communication. The system uses H.264 for encoding and decoding, in addition, it communicates by RTP protocol and SIP protocol. The system is designed and implemented combining the plans above. The result of the communication proves that the system performs well and meets the requirements of real-time and good communication quality.
Editing dynamic human motions via momentum and force

We present an integrated framework for interactive editing of the momentum and external forces in a motion capture sequence. Allowing user control of the momentum and forces provides a powerful and intuitive editing tool for dynamic motions. To make a higher jump, for example, the user simply increases the linear momentum in the vertical direction, while our system automatically calculates a motion that maintains both the same landing position and physical plausibility. Our key insight is using trajectory optimization based on normalized dynamics to simultaneously propagate momentum and force space changes. We demonstrate our approach with edits of long sequences of dynamic actions, including kicks, jumps, and spins.
In their own voices: Development of English as a gender-neutral language

This study explores how learning English among one subset of English learners, Asian female international students at US colleges, contributes to the larger project of advancing gender equality. Using their narratives, we ask why Asian female international students invest so much of their identities and effort into learning English. We discuss the ways in which their endeavours may even silently promote the development of English as a gender-neutral language. The population of Asian students offers a compelling case of how the English language is potentially transformed via its spread to this English learner population and how it presents new avenues for identity formation for the growing number of female English users worldwide (cf. Brutt-Griffler, 2010: 232).
Plant Nucleotide Binding Site–Leucine-Rich Repeat (NBS-LRR) Genes: Active Guardians in Host Defense Responses

The most represented group of resistance genes are those of the nucleotide binding site–leucine-rich repeat (NBS-LRR) class. These genes are very numerous in the plant genome, and they often occur in clusters at specific loci following gene duplication and amplification events. To date, hundreds of resistance genes and relatively few quantitative trait loci for plant resistance to pathogens have been mapped in different species, with some also cloned. When these NBS-LRR genes have been physically or genetically mapped, many cases have shown co-localization between resistance loci and NBS-LRR genes. This has allowed the identification of candidate genes for resistance, and the development of molecular markers linked to R genes. This review is focused on recent genomics studies that have described the abundance, distribution and evolution of NBS-LRR genes in plant genomes. Furthermore, in terms of their expression, NBS-LRR genes are under fine regulation by cis- and trans-acting elements. Recent findings have provided insights into the roles of alternative splicing, the ubiquitin/proteasome system, and miRNAs and secondary siRNAs in the regulation of NBS-LRR gene expression at the post-transcriptional, post-translational and epigenetic levels. The possibility to use this knowledge for genetic improvement of plant resistance to pathogens is discussed.
Power of the Few vs. Wisdom of the Crowd: Wikipedia and the Rise of the Bourgeoisie

Wikipedia has been a resounding success story as a collaborative system with a low cost of online participation. However, it is an open question whether the success of Wikipedia results from a “wisdom of crowds” type of effect in which a large number of people each make a small number of edits, or whether it is driven by a core group of “elite” users who do the lion’s share of the work. In this study we examined how the influence of “elite” vs. “common” users changed over time in Wikipedia. The results suggest that although Wikipedia was driven by the influence of “elite” users early on, more recently there has been a dramatic shift in workload to the “common” user. We also show the same shift in del.icio. us, a very different type of social collaborative knowledge system. We discuss how these results mirror the dynamics found in more traditional social collectives, and how they can influence the design of new collaborative knowledge systems.
A Deductive Approach to Program Synthesis

Program synthesis is the systematic derivation of a program from a given specification. A deductive approach to program synthesis is presented for the construction of recursive programs. This approach regards program synthesis as a theorem-proving task and relies on a theorem-proving method that combines the features of transformation rules, unification, and mathematical induction within a single framework.
Decentralized coordination of transactional processes in peer-to-peer environments

Business processes executing in peer-to-peer environments usually invoke Web services on different, independent peers. Although peer-to-peer environments inherently lack global control, some business processes nevertheless require global transactional guarantees, i.e., atomicity and isolation applied at the level of processes. This paper introduces a new decentralized serialization graph testing protocol to ensure concurrency control and recovery in peer-to-peer environments. The uniqueness of the proposed protocol is that it ensures global correctness without relying on a global serialization graph. Essentially, each transactional process is equipped with partial knowledge that allows the transactional processes to coordinate. Globally correct execution is achieved by communication among dependent transactional processes and the peers they have accessed. In case of failures, a combination of partial backward and forward recovery is applied. Experimental results exhibit a significant performance gain over traditional distributed locking-based protocols with respect to the execution of transactions encompassing Web service requests.
Activation of cardiac vagal afferents by oxygen-derived free radicals in rats.

Myocardial ischemia and reperfusion can evoke excitation of cardiac vagal afferent nerve endings and activation of a cardiogenic depressor reflex (Bezold-Jarisch effect). We postulate that oxygen-derived free radicals, which are well known to be produced during prolonged ischemia and reperfusion, contribute to this excitation. Hydroxyl radicals derived from hydrogen peroxide (H2O2) activate abdominal sympathetic afferents and produce reflex excitation of the cardiovascular system. However, it is not known whether inhibitory vagal cardiac afferents are activated by oxygen-derived free radicals. We recorded activity from 52 single vagal afferent fibers in 29 rats; the endings of these fibers were located in the walls of all four chambers of the heart. Thirty-three (63%) of these fibers were classified as chemosensitive C-fiber endings because of their irregular discharge under resting conditions, their activation in response to the topical application of capsaicin (1 to 10 micrograms) to the surface of the heart encompassing the receptive field, and their conduction velocities. Fourteen (27%) of the remaining fibers were found to be mechanoreceptors. Topical application of H2O2 to the heart activated 50% of the chemosensitive endings and did not directly affect cardiac mechanoreceptors. Activity increased by 498% at a dose of 3 mumol (P < .001). This effect was reproducible and dose dependent and was not due to [H+]. Topical application of xanthine/xanthine oxidase (20 mmol/0.03 mU) activated 8 of the 12 chemosensitive fibers tested and had no direct effect on mechanosensitive fibers. Activity increased by 287% (P < .001). (ABSTRACT TRUNCATED AT 250 WORDS)
