Hopf Algebra Equivariant Cyclic Homology and Cyclic Homology of Crossed Product Algebras

We introduce the cylindrical module $A \natural \mathcal{H}$, where $\mathcal{H}$ is a Hopf algebra and $A$ is a Hopf module algebra over $\mathcal{H}$. We show that there exists an isomorphism between $\mathsf{C}_{\bullet}(A^{op} \rtimes \mathcal{H}^{cop})$ the cyclic module of the crossed product algebra $A^{op} \rtimes \mathcal{H}^{cop} $, and $\Delta(A \natural \mathcal{H}) $, the cyclic module related to the diagonal of $A \natural \mathcal{H}$. If $S$, the antipode of $\mathcal{H}$, is invertible it follows that $\mathsf{C}_{\bullet}(A \rtimes \mathcal{H}) \simeq \Delta(A^{op} \natural \mathcal{H}^{cop})$. When $S$ is invertible, we approximate $HC_{\bullet}(A \rtimes \mathcal{H})$ by a spectral sequence and give an interpretation of $ \mathsf{E}^0, \mathsf{E}^1$ and $\mathsf{E}^2 $ terms of this spectral sequence.
Long-Term Career Impact and Professional Applicability of the Study Abroad Experience.

I n t r o d u c t i o n Research shows that study abroad experience affects professional qualifications. It is evident that employers value the skills and knowledge potentially gained from study abroad and that these competencies are transferable on the job. Johnson and Kaufman note that specific focus is given to intercultural competencies gained from an international experience and that this could be essential to career success in the global marketplace ( Johnson and Kaufman 2005). Others point to various marketable and real world skills that are carried by study abroad college graduates (Asia Society and The Goldman Sachs Foundation 2005). In a RAND Corporation study, employers for globalized jobs cite cross-cultural competencies and interpersonal skills used in problem-solving as prime criteria used when evaluating job candidates (Matherly and Nolting 2007). In another study, CEO perspectives were obtained to help develop and define an employee profile for high potential in the workplace. Findings indicate that “studying abroad and internationally oriented studies are mentioned as essential and basic requirements for enhancing talent” and that there is a need for “people who can work from a variety of perspectives” (Hermans 2007, 513–514). Results from another employers survey found that European mobile (study abroad) alumni have stronger professionally relevant competences then non-mobile students (Teichler and Janson 2007, 486–495). Study abroad outcomes assessments are routinely conducted immediately following a participant’s return from abroad, or shortly after graduation. The majority of research focuses on the impact of study abroad in the areas of language acquisition, knowledge gained, and changes in personal values, attitudes, and interests. The Georgetown Consortium Project is a comprehensive example of such. The central question that drove the research was, “What is it that our students are learning while abroad? ” With a wide-ranging scope of focus, student learning was evaluated in three areas: gains in second-language oral proficiency, gains in intercultural sensitivity, and learning within a disciplinary context (Balkcum, Scheid, Vande Berg, and Whalen 2004). Further studies exploring the immediate impact of study abroad and provide evidence of study abroad out-
Efficient super-elasticity handling in mass-spring systems

This paper describes a technique for constraining models based on mass-spring systems to avoid the "super-elasticity" phenomenon. It employs a velocity directional modification approach and pays special attention to the order of adjustment of the individual springs in the model. An algorithm for obtaining that order is outlined. Images, showing the results of applying this approach in two different scenarios are given at the end of the paper.
PENERAPAN ART THERAPY UNTUK MENINGKATKAN SELF-ESTEEM REMAJA PEREMPUAN DI LEMBAGA BIMBINGAN BELAJAR X

Pada masa remaja seseorang rentan mengalami penurunan self-esteem. Remaja yang lebih rentan mengalami penurunan self-esteem adalah remaja perempuan, hal ini disebabkan remaja perempuan cenderung kurang puas dengan body imagenya. Self-esteem yang kurang baik berkaitan dengan tingkat depresi yang tinggi. Oleh karena itu, art therapy diterapkan untuk meningkatkan self-esteem dari 5 remaja perempuan di lembaga bimbingan belajar X. Beberapa penelitian sebelumnya menunjukkan bahwa art therapy efektif untuk meningkatkan self-esteem, karena art therapy dapat membantu seseorang untuk mengeksplorasi perasaan, sehingga dapat membantu mereka mengungkapan perasaan dan emosi yang tidak dapat diungkapkan dengan kata-kata. Penelitian ini menggunakan mixed method one group pre-test post-test design dengan menggunakan alat ukur State Self-Esteem Scale, wawancara semi terstruktur, dan draw a person test yang dianalisa untuk mengetahui perbandingan hasil sebelum dan sesudah pemberian intervensi. Berdasarkan hasil observasi dan draw a person test menunjukkan adanya peningkatan selfesteem dari kelima partisipan, namun berdasarkan alat ukur State Self-Esteem Scale hanya empat partisipan yang menunjukkan peningkatan skor total. Berdasarkan hasil tersebut dapat disimpulkan bahwa art therapy cukup efektif untuk meningkatkan self-esteem dari lima remaja perempuan di lembaga bimbingan belajar X.
Isoprene oxidation products are a significant atmospheric aerosol component

Abstract. Glycolaldehyde, hydroxyacetone, and methylglyoxal, which are known isoprene oxidation products, were collected during two field experiments using an annular denuder sampling system and compared to a model calculation. The compounds in gas and aerosol phases were determined during both experiments. Global variation and distribution of the aerosol mass contribution of the compounds were predicted using the measurements, the box model results, and gas-phase concentrations and humidity simulated by a global 3-D model. Here we report the estimates of a global annual contribution of 35 (10–120) Tg of aerosol organic matter from isoprene.
Locate, Cluster and Conquer: A Scalable Topology-aware Overlay Multicast

Recent proposals in multicast overlay networks have demonstrated the importance of exploiting underlying network topology data to construct efficient overlays. While they avoid virtual coordinates embedding and fixed landmarks measurements, these topology-aware proposals often rely on incremental and periodic refinements to improve each node's position in the delivery tree. However, these approaches are neither scalable, as they induce high communication cost due to refinement overhead, nor efficient because long convergence time is necessary to obtain a stabilized structure. In this paper, we propose a novel highly scalable locating algorithm to initially direct newcomers to the closest set of existing nodes. Each newcomer sends request to a few nodes to build its neighborhood information. On the basis of the locating process, we build a two-level topology-aware scheme, namely LCC. We evaluated the LCC scheme using real WAN deployment and by extensive simulation. WAN experimentation was carried over the PlanetLab wide area testbed using more than 200 machines, and simulations were performed using the BRITE topology generator with over 10000 nodes. We compare the scalability and efficiency of LCC with that of initially-randomly connected overlays. Results demonstrate promising performance of LCC, and show that locating-based overlays achieve 70\% less link adjustments than initially randomly-connected structures, with three times faster convergence. Moreover, while being accurate, the locating process entails modest resources and incurs low overhead during new nodes arrivals.
Studies on terrestrial herbaceous plants tolerance to excess heavy metals: methodological approach.

Plant tolerance to heavy metals is а scientific issue attracting significant attention due to the possible use of tolerant plants for phytoremediation purposes as well as due to the fact that the molecular mechanisms of this phenomenon are not clear enough. Despite of the increasing volume of research on the problem, the available information in many cases is incomplete and/or difficult to compare with other studies because of the significant differences in the experimental designs, range of used metal concentrations, exposure time, etc. In this review-paper both the advantages and limitations of the used experimental designs as well as the methods for evaluation of heavy metal tolerance are briefly discussed.

The Performance of Applications and Operating Systems on Simple IRAM Architectures

Computer memory systems are increasingly a bottleneck limiting the performance of applications and operating systems. IRAM architectures, which integrate a CPU with DRAM main memory on a single chip, have the potential to liberate systems from this bottleneck. In order to better understand the performance trade-offs of a variety of simple IRAM architectures we used the SimOS simulation environment to evaluate seven possible IRAM configurations and one conventional machine configuration. For each configuration, we analyzed the behavior of several standard integer and floating-point benchmark applications as well as memory and operating system microbenchmarks. Our simulation results for these benchmarks indicate that simple IRAM systems of 1998 ought to be as much as 40% faster for memory-intensive applications and nearly twice as fast for memory-intensive operating system services compared to a hypothetical conventional machine of 1998.
Towards Controllability of Wireless Network Quality using Mobile Robotic Routers

We consider a problem of robotic router placement and mobility control with the objective of formation and maintenance of an optimal communication network between a set of transmitter-receiver pairs. In this scenario, the communication path between any transmitter-receiver pair contains a predetermined set of mobile robotic routers nodes. The goal of this work is to design an algorithm to optimize the positions of the robotic nodes to improve the overall performance of the network. We define the optimization metric to be the minimum of the Signal to Interference plus Noise Ratios (SINR) over all the links. In this manuscript, we propose two optimization algorithms to solve this problem in a centralized and a decentralized manner, respectively.We also demonstrate the performances of both algorithms based on a set of simulation experiments.
Self-Exfiltration : The Dangers of Browser-Enforced Information Flow Control

Since the early days of Netscape, browser vendors and web security researchers have restricted out-going data based on its destination. The security argument accompanying these mechanisms is that they prevent sensitive user data from being sent to the attacker’s domain. However, in this paper, we show that regulating web information flow based on its destination server is an inherently flawed security practice. It is vulnerable to self-exfiltration attacks, where an adversary stashes stolen information in the database of a whitelisted site, then later independently connects to the whitelisted site to retrieve the information. We describe eight existing browser security mechanisms that are vulnerable to these “self-exfiltration” attacks. Furthermore, we discovered at least one exfiltration channel for each of the Alexa top 100 websites. None of the existing information flow control mechanisms we surveyed are sufficient to protect data from being leaked to the attacker. Our goal is to prevent browser vendors and researchers from falling into this trap by designing more systems that are vulnerable to self-exfiltration.
The UDP-glucose:p-Hydroxymandelonitrile-O-Glucosyltransferase That Catalyzes the Last Step in Synthesis of the Cyanogenic Glucoside Dhurrin in Sorghum bicolor

The final step in the biosynthesis of the cyanogenic glucoside dhurrin in Sorghum bicolor is the transformation of the labile cyanohydrin into a stable storage form byO-glucosylation of (S)-p-hydroxymandelonitrile at the cyanohydrin function. The UDP-glucose:p-hydroxymandelonitrile-O-glucosyltransferase was isolated from etiolated seedlings of S. bicoloremploying Reactive Yellow 3 chromatography with UDP-glucose elution as the critical step. Amino acid sequencing allowed the cloning of a full-length cDNA encoding the glucosyltransferase. Among the few characterized glucosyltransferases, the deduced translation product showed highest overall identity to Zea maysflavonoid-glucosyltransferase (Bz-Mc-2 allele). The substrate specificity of the enzyme was established using isolated recombinant protein. Compared with endogenousp-hydroxymandelonitrile, mandelonitrile, benzyl alcohol, and benzoic acid were utilized at maximum rates of 78, 13, and 4%, respectively. Surprisingly, the monoterpenoid geraniol was glucosylated at a maximum rate of 11% compared withp-hydroxymandelonitrile. The picture that is emerging regarding plant glucosyltransferase substrate specificity is one of limited but extended plasticity toward metabolites of related structure. This in turn ensures that a relatively high, but finite, number of glucosyltransferases can give rise to the large number of glucosides found in plants.
Effects of Word Assignment in LDA for News Topic Discovery

In traditional LDA, latent variables are inferred from the "bag-of-words" assumption, in which word order is ignored. This bag-of-words assumption has gained recognition in terms of computational efficiency, whereas it is regarded impractical in many language model applications where word order is essential. In this study, we proposed word concatenation based on morphological rules as compounds and built the connection between compounds and topics. We used three categories including politics, economics, and life of Yahoo! Taiwan news from May/23/2013 to June/20/2013 and also extracted 1/3 of the news pool at random from each category as the mixed dataset. We compared unigrams and compounds in terms of topic coherence and performance, the result shows that the proposed model has a higher value of perplexity, while it illustrates more accurate meaning and computational efficiency than traditional LDA.
An Augmented ADMM Algorithm With Application to the Generalized Lasso Problem

ABSTRACT In this article, we present a fast and stable algorithm for solving a class of optimization problems that arise in many statistical estimation procedures, such as sparse fused lasso over a graph, convex clustering, and trend filtering, among others. We propose a so-called augmented alternating direction methods of multipliers (ADMM) algorithm to solve this class of problems. Compared to a standard ADMM algorithm, our proposal significantly reduces the computational cost at each iteration while maintaining roughly the same overall convergence speed. We also consider a new varying penalty scheme for the ADMM algorithm, which could further accelerate the convergence, especially when solving a sequence of problems with tuning parameters of different scales. Extensive numerical experiments on the sparse fused lasso problem show that the proposed algorithm is more efficient than the standard ADMM and two other existing state-of-the-art specialized algorithms. Finally, we discuss a possible extension and some interesting connections to two well-known algorithms. Supplementary materials for the article are available online.
What Goes Up Must Come Down? Explaining Recent Changes in Public Assistance Caseloads

Over the past decade, public assistance caseloads have increased rapidly to an historical high point and then decreased with even greater speed to their lowest level in decades. Several recent papers have focused on the rise in Aid to Families with Dependent Children (AFDC) caseloads in the early 1990s and the turn-around in the mid-1990s. This research indicates that both macroeconomic factors and program factors appear to be important for these changes. A key question is whether these recent declines are permanent, and how much they might turn around in a more sluggish economy. This paper focuses on the relationship between recent caseload changes and the overall economy, comparing estimates from a wide variety of models using both annual and monthly data. By using monthly data, which is available through late 1998, this paper also presents several rough estimates of the impact of welfare reform post-1996. The Food Stamp program has also experienced major program changes, although it has remained relatively unchanged for single mothers and their children who once participated in AFDC. This paper also provides a detailed comparative analysis of AFDC/TANF caseload changes with Food Stamp caseload changes.
‘Be good, know the rules’: Children’s perspectives on starting school and self-regulation

Despite the importance of self-regulation for school readiness and success across the lifespan, little is known about children’s conceptions of this important ability. Using mixed-method interviews, this research examined kindergarten children’s (n = 57) perspectives on self-regulation in a disadvantaged area in Dublin, Ireland. Children depicted school as requiring regulation of their emotional, cognitive and behavioural responses. They characterised school as a dynamic setting, placing emphasis on the regulatory challenges of the outdoor environment. Children also described difficulties associated with navigating complex social interactions, often without assistance from external supports. The results inform strategies to support children’s emerging self-regulation abilities.
A Dynamic Power-Aware Scheduling of Mixed-Criticality Real-Time Systems

Recent safety-critical real-time embedded systems have enabled multiple real-time applications with different criticalities to run in a single system. Thus, many studies have been done not only on providing timing guarantee for tasks having different criticality levels, but also on other required functional properties such as energy reduction. Since many processors are equipped with dynamic voltage and frequency scaling (DVFS) capacity, energy can be saved by reducing the processor frequency. In this paper, we provide a new dynamic power-aware mixed-criticality real-time scheduling. The proposed scheme can reduce energy more by using slack time for reserved time for high-criticality tasks. Throughout simulation results, we show that the proposed scheme reduces more energy and that the optimal frequency levels in the static scheme are not optimal in the dynamic scheme.
The Thought Disorder Index : A Reliability Study

This article reports interrater reliability among 4 teams of raters who independently evaluated thought disorder in 20 Rorschach protocols using the Thought Disorder Index (TDI). Intraclass correlation coefficients were calculated to assess the degree of association among the 4 teams for total thought disorder scores, severity levels, and qualitative thought disorder factors. Highly acceptable agreement was obtained. Spearman rank order correlation coefficients for these same variables were significant for all possible pairings of teams. A repeated-measures analysis of variance indicated that the absolute amount of thought disorder tagged by each team differed even though the teams' relative rankings of thought disorder among subjects was very similar. Such scoring differences reflect individual differences in threshold for detecting deviant thinking.
Sticky worms: adhesion complexes in C. elegans

Caenorhabditis elegans is a powerful model system for investigating the establishment, regulation and function of adhesive structures in vivo. C. elegans has several adhesion complexes related to those in vertebrates. These include: (1) epithelial apical junctions, which have features of both adherens and tight junctions; (2) dense bodies, which are muscle-attachment structures similar to focal adhesions; (3) fibrous organelles, which resemble hemidesmosomes and mediate mechanical coupling between tissues; and (4) a putative dystrophin-glycoprotein complex that has potential roles in muscle function and embryogenesis. Recent work has increased our understanding of these structures and has given new insights into the functions of their vertebrate counterparts.
Insomnia With Objective Short Sleep Duration Is Associated With Type 2 Diabetes

OBJECTIVE We examined the joint effects of insomnia and objective short sleep duration, the combination of which is associated with higher morbidity, on diabetes risk. RESEARCH DESIGN AND METHODS A total of 1,741 men and women randomly selected from Central Pennsylvania were studied in the sleep laboratory. Insomnia was defined by a complaint of insomnia with duration of ≥1 year, whereas poor sleep was defined as a complaint of difficulty falling asleep, staying asleep, or early final awakening. Polysomnographic sleep duration was classified into three categories: ≥6 h of sleep (top 50% of the sample); 5–6 h (approximately third quartile of the sample); and ≤5 h (approximately the bottom quartile of the sample). Diabetes was defined either based on a fasting blood glucose >126 mg/dl or use of medication. In the logistic regression model, we simultaneously adjusted for age, race, sex, BMI, smoking, alcohol use, depression, sleep-disordered breathing, and periodic limb movement. RESULTS Chronic insomnia but not poor sleep was associated with a higher risk for diabetes. Compared with the normal sleeping and ≥6 h sleep duration group, the highest risk of diabetes was in individuals with insomnia and ≤5 h sleep duration group (odds ratio [95% CI] 2.95 [1.2–7.0]) and in insomniacs who slept 5–6 h (2.07 [0.68–6.4]). CONCLUSIONS Insomnia with short sleep duration is associated with increased odds of diabetes. Objective sleep duration may predict cardiometabolic morbidity of chronic insomnia, the medical impact of which has been underestimated.
