Efficient transmission of periodic data that follows a consistent daily pattern: experimental study of transmitting performance data in a wireless network

Performance management is an essential part of network management. Part of the performance management application is the task of monitoring network resources and periodically transmitting the performance statistics from all the managed nodes in the network to the Operation and Management Centre (OMC). In this paper, we will show that most of the daily performance data of a node within a wireless network follows a consistent pattern with minor changes from one day to the next. Using this behaviour, we introduce an algorithm that would reduce the amount of data transmitted daily by 52% with no loss of information and by 58% with a 10% threshold on information loss. Furthermore, we introduce an extension to the algorithm where both the transmitter and the receiver make a distinction between the behaviour of weekdays and weekends. Our work has been applied to a commercially deployed wireless network.
Dynamic Social Network Modeling and Analysis: Workshop Summary and Papers

In the summer of 2002, the Office of Naval Research asked the Committee on Human Factors to hold a workshop on dynamic social network and analysis. The primary purpose of the workshop was to bring together scientists who represent a diversity of views and approaches to share their insights, commentary, and critiques on the developing body of social network analysis research and application. The secondary purpose was to provide sound models and applications for current problems of national importance, with a particular focus on national security. This workshop is one of several activities undertaken by the National Research Council that bears on the contributions of various scientific disciplines to understanding and defending against terrorism. The presentations were grouped in four sessions a " Social Network Theory Perspectives, Dynamic Social Networks, Metrics and Models, and Networked Worlds a " each of which concluded with a discussant-led roundtable discussion among the presenters and workshop attendees on the themes and issues raised in the session.

Based on the dynamic model, airship response modes are analyzed and control challenges are pointed out. The present work provides a starting point for robotics and control researchers interested in utilizing airships as robotic aerial vehicles.
Personal Fabrication

While fabrication technologies have been in use in industry for several decades, expiring patents have recently allowed the technology to spill over to technology-enthusiastic “makers”. The big question now is whether the technology will further progress towards consumers, which would allow the technology to scale from hundreds of thousands of users to hundreds of millions of users. Such a transition would enable consumers to use computing not just to process data, but for physical matter. This holds the promise of democratizing a whole range of fields preoccupied with physical objects, from product design to interior design, to carpentry, and to some areas of mechanical and structural engineering. It would bring massive, disruptive change to these industries and their users. We analyze similar trends in the history of computing that made the transition from industry to consumers, such as desktop publishing and home video editing, and come to the conclusion that such a transition is likely. Our analysis, however, also reveals that any transition to consumers first requires a hardware + software system that embodies the skills and expert knowledge that consumers lack: (1) hardware and materials that allow fabricating the intended objects, (2) software that embodies domain knowledge, (3) software that embodies the know-how required to operate the machinery, and (4) software that provides immediate feedback and supports interactive exploration. At the same time, sustained success will only be possible if we also consider future implications, in particular (5) sustainability and (6) intellectual property. We argue that researchers in HCI and computer graphics are well equipped for tackling these six challenges. We survey the already existing work and derive an actionable research agenda. P.

Deep Domain Adaptation Hashing with Adversarial Learning

The recent advances in deep neural networks have demonstrated high capability in a wide variety of scenarios. Nevertheless, fine-tuning deep models in a new domain still requires a significant amount of labeled data despite expensive labeling efforts. A valid question is how to leverage the source knowledge plus unlabeled or only sparsely labeled target data for learning a new model in target domain. The core problem is to bring the source and target distributions closer in the feature space. In the paper, we facilitate this issue in an adversarial learning framework, in which a domain discriminator is devised to handle domain shift. Particularly, we explore the learning in the context of hashing problem, which has been studied extensively due to its great efficiency in gigantic data. Specifically, a novel Deep Domain Adaptation Hashing with Adversarial learning (DeDAHA) architecture is presented, which mainly consists of three components: a deep convolutional neural networks (CNN) for learning basic image/frame representation followed by an adversary stream on one hand to optimize the domain discriminator, and on the other, to interact with each domain-specific hashing stream for encoding image representation to hash codes. The whole architecture is trained end-to-end by jointly optimizing two types of losses, i.e., triplet ranking loss to preserve the relative similarity ordering in the input triplets and adversarial loss to maximally fool the domain discriminator with the learnt source and target feature distributions. Extensive experiments are conducted on three domain transfer tasks, including cross-domain digits retrieval, image to image and image to video transfers, on several benchmarks. Our DeDAHA framework achieves superior results when compared to the state-of-the-art techniques.
The Use of Social Media for Academic Purposes in Student’ Learning Process

Social media has a great impact on student’s lives. They spend a considerable part of their time on these pages. Social media includes social networking sites (SNSs), virtual gaming sites, video sites, projects sites and blogs. Millions of students are using these Web 2.0 tools worldwide, there hasn’t been much research regarding the educational use of social networking. The purpose of this study is to investigate attitudes toward the use of social media in learning process. The findings suggest that social media and social network sites in particular can be very useful as an educational tool. Students using SNSs as a supplement to their curriculum showed that they loved spending time on SNSs, and exercises, videos and other sharing in group are useful for their academic purposes. The paper concludes with suggestions for improving academic purpose and it highlights the fact that every educator must regard how their current teaching standard can be improved or how they could perhaps be replaced because of a prevalent web.

Created Value as a Sustainability KPI for Integrated Reporting

Integrated reporting shows a panoramic view of the firm’s status. IIRC’s framework is principles-based, it does not provide specific key performance indicators (KPIs) for integrated thinking and reporting. Through empirical analyses of all listed firms in 34 countries, our study provides the first evidence that value added information is actually useful for evaluating the firm’s financial stability and sustainability. We focus on firms that have survived for more than 100 years and that have already achieve sustainability. We find two distinguishing facts; the value added distributed to stakeholders other than shareholders is significantly larger and the stability of profitability is significantly higher in sustainable firms. These two KPIs are equivalent to the two interrelated aspects of value under the IIRC framework. We therefore propose the value added distribution and the stability of profitability as a sustainability KPIs for integrated reporting. Keyword Created Value, Integrated Reporting, Sustainability

Promoting Resistance of Snap Bean against Damping-off Disease Caused by Rhizoctonia solani Using the Integration between Some Antioxidants and Bioagents

In both greenhouse and field experiments, the effect of three antioxidants, i.e., ascorbic acid, oxalic acid and salicylic acid (at 5.0 mM) as a seed soaking, followed by the bioagents, i.e., Bacillus megaterium, B. subtilis, Serratia marcesens, Trichoderma harzianum, T. lignorum and T. viride as a seed coating were appliedagainst damping-off disease of bean plants, in addition to study the biochemical response of treated plants. Results revealed that all tested treatments significantly reduced preand post-emergence damping-off in addition to inducing an increase in survived plants under both conditions. Complete protection of damping-off incidence was obtained in the case of using salicylic acid as a seed soaking and Serratia marcesens as a seed coating compared to other treatments and control. All tested treatments significantly increased either fresh or dry weight of shoots and roots per plant. Moreover, under field conditions, the best integration treatments were ascorbic acid, oxalic acid and salicylic acid as a seed soaking and with S. marcesens as a seed coating where the lowest pre and post emergence damping-off % ranged between (3.88 and 7.4%); in addition to increasing the survival plants more than (88.5%), but other treatments showed moderate effect. As for, biochemical response of snap bean plants under greenhouse condition results indicated that all tested treatments increased the flavonoids content and affected positively the activities peroxidase, polyphenoloxidase and phenylalanine ammonia lyase, chitinase and β-1,3-glucanase enzymes of the plants. As for chitinase activity, the most effective treatment (with efficacy being 315.21%) was ascorbic acid with S. Marcescens. On the other hand, the highest increase of β-1,3-glucanase activity was recorded with the integration of oxalic acid and each of S. marcescens and B. megateriu (382.50 and 316.88%), respectively were recorded.
Proteomic identi fi cation of germline proteins in Caenorhabditis elegans B

Sexual reproduction involves fusion of 2 haploid gametes to form diploid offspring with genetic contributions from both parents. Gamete formation represents a unique developmental program involving the action of numerous germline-specific proteins. In an attempt to identify novel proteins involved in reproduction and embryonic development, we have carried out a proteomic characterization of the process in Caenorhabditis elegans. To identify candidate proteins, we used 2D gel electrophoresis (2DGE) to compare protein abundance in nucleus-enriched extracts from wild-type C. elegans, and in extracts from mutant worms with greatly reduced gonads (glp-4(bn2) worms reared at 25! C); 84 proteins whose abundance correlated with germline presence were identified. To validate candidates, we used feeding RNAi to deplete candidate proteins, and looked for reduction in fertility and/or germline cytological defects. Of 20 candidates so screened for involvement in fertility, depletion of 13 (65%) caused a significant reduction in fertility, and 6 (30%) resulted in sterility (<5 % of wild-type fertility). Five of the 13 proteins with demonstrated roles in fertility have not previously been implicated in germline function. The high frequency of defects observed after RNAi depletion of candidate proteins suggests that this approach is effective at identifying germline proteins, thus contributing to our understanding of this complex organ.
MiR-182 regulates proliferation and apoptosis by targeting FBW 7 in glioma cells

Background: Glioblastoma (GBM) is the most malignant brain tumor and exhibits aggressive phenotype. Studies have shown that microRNA (miR) acts as regulator in GBM, while the effect of miR-182 on GBM is still unclear. The aim of this study was to explore the role of miR-182 in GBM. Methods: miR-182-KO cells were generated using Crispr-cas 9 system. MTS and clonogenic assays were used to determine cell proliferation. Flow cytometry was performed for cell cycle and apoptosis analysis. Western blot and qRT-PCR assays were used to assess the alterations of signaling pathway. Nude mouse xenograft model was used to evaluate the role of miR-182 in vivo. Results: We found that CRISPR-mediated miR-182 knockout enhanced cell cycle arrest and inhibited proliferation. We further identified the F-box and WD repeat domain containing 7 (FBW7) as a target gene of miR-182 in GBM. Furthermore, inhibition of miR-182 induced VEGF-A downregulation. Inhibition of miR-182 promotes apoptosis via FBW-7-mediated Mcl-1 degradation in GBM. In addition, deficiency of miR-182 reduced tumor growth. Finally, our data showed that miR-182 level was inversely correlated with FBW7 in GBM patients. Conclusions: In conclusion, our study suggests that miR-182 is a potential therapeutic target for GBM treatment.
Biophysical modelling to assess population connectivity and interannual variability in the recruitment patterns of jack mackerel in the southeastern Pacific

The jack mackerel (Trachurus murphyi) population has historically supported one of the most important fisheries in the southeastern Pacific Ocean, however, catches, biomass and recruitment levels have decreased steadily over the last decade to a minimum in 2008. In this context, there is increasing interest in studying jack mackerel recruitment dynamics and population structure under a scenario of small population size. At present, numerous transport simulation studies have demonstrated the importance of hydrodynamics for advection, transport and finally the recruitment of early stages of marine pelagic species. Furthermore, the dispersion of early stages is one of the key factors for population connectivity, which is especially important for species with broad geographic distribution. In order to study the patterns of connectivity between different areas of spawning and the nursery ground and its effect on the recruitment dynamics, an individual-based model (IBM) was coupled to a validated hydrodynamic model to simulate annual patterns in the early life history of jack mackerel for the period 1994-2013. The IBM configuration included realistic initial conditions related to the location and synchrony of spawning in three spawning grounds: coastal area off Peru, coastal area off northern Chile and oceanic area off central Chile. Moreover, the transport process included a scheme for eggs buoyancy and vertical migration for larvae. Results showed that: i) as product of oceanographic dynamics off the coast of Peru, the dispersion is highly dependent on the location of spawning area: if the jack mackerel spawning area is located off northern Peru, then predominates high advection towards offshore; on the other hand if the spawning area is located in the south-central area of Peru, there exist a greater retention, dispersion towards the south and connectivity to the nursery ground situated in the coastal area off northern Chile and southern Peru; ii) the spawning area located in northern Chile shows high levels of retention (>80%) and low interannual variability; iii) the surface circulation pattern associated with the subtropical gyre supports connectivity between the main spawning area located in the oceanic area off south-central Chile and the nursery ground. Furthermore, we propose that our simulations are coherent with the existing recruitment estimation and therefore open new possibilities for fisheries management. Finally, the proposed modelling scheme reasonably simulates the early life history of jack mackerel and can also be considered to understanding relative stock structure hypotheses. The high dispersion range and spatial overlap of modelled recruitments support the hypothesis of a single population, which is consistent with the genetic evidence of jack mackerel in the southeastern Pacific.
The determinants of idiosyncratic volatility

This paper investigates the time-series and cross-sectional determinants of idiosyncratic volatility. In the time-series, we find that firm-level volatility is positively related to increased institutional ownership, increased firm focus, and leverage. Furthermore, the explanatory power of market-model regressions has decreased over our sample period, and is negatively related to institutional ownership, increased firm focus, and leverage. In the cross-section, changes in idiosyncratic volatility are positively related to changes in institutional ownership. In addition, we find evidence of a positive relation between changes in ownership of equities by mutual funds and changes in idiosyncratic volatility after controlling for changes in institutional ownership. Last, when we condition on return, we find that there is a decrease in idiosyncratic volatility following both positive and negative returns. This finding is inconsistent with the leverage hypothesis. The decrease in idiosyncratic volatility is consistent, however, with a reduction in asymmetric information following the release of firm specific news.
Redispatch in Zonal Pricing Electricity Markets

Zonal pricing electricity markets operate sequentially. First, the suppliers compete in a spot market. Second, to alleviate the congestion in the transmission line, in a redispatch market, the suppliers in the importing node are called into operation to increase their production, and the suppliers in the exporting node are compensated to reduce their production. I characterize the equilibrium in a zonal market when the competition is imperfect and the spot and redispatch markets operate sequentially. I also work out the equilibrium when the transmission line is taken into account in the spot market, i.e., it is not necessary to introduce a redispatch market to alleviate the congestion in the transmission line. I find that the consumers' welfare and suppliers' profits depend crucially on the type of redispatch design implemented by the auctioneer, and that could introduce long term investment distortions.

Occupational Health Risks Among Cosmetologist : A Case Of Kinondoni Municiparity Dar Es Salaam , Tanzania

Cosmetologists and consumers often assume hairdressing, nail salons and the products used are safe. Unfortunately, they are subjected to various occupational health risks such as some of chemicals ingredients used in nail and hair products have been tied to cancer, miscarriages and lung diseases. Other problems are due to prolonged standing, poor ventilation, poor lighting and unhygienic practice. This study assesses occupational health hazards and illnesses awareness among hairdresser and nail salon workers. By using questionnaire and interview a total of 264 workers participated in the study results shows that majority 88.64% (n=234) are affected with musculoskeletal disorders, 82.58 (n=218) physical injuries, dermatitis 73.86 (n=195), fungal infection 61.36% (n=162), respiratory problems 54.17% (n=143) and infectious diseases 37.88% (100). Other occupational health illness reported by some of respondent includes, nail infection 25.76% (n=68), tuberculosis 21.21% (n=56), Ulcers 9.85% (n=26), cancer 6.44% (n=17), and reproductive or birth disorder 5.30% (n=14). Safety advocates are encouraged by the increased awareness but want better safeguards for salon workers. Although people thought consumers are more vulnerable, but workers in both nail and hair salons can be exposed to hazardous chemicals. Clearly, action is needed to improve conditions for salon workers and to help create and ensure healthier workplaces in the future. Recommendations for salon workers, salon owners, salon product manufacturers, and researchers, as well as long-term policy solutions must be designed so as to improve the health and safety of salon workers.
