Electro-thermal characterization of GaN HEMT on Si through selfconsistent energy balance-cellular Monte Carlo device simulations

In order to assess the mechanisms of self-heating observed in GaN HEMTs on Si substrates, we have performed the electro-thermal characterization of an experimental device in terms of the simulation of its DC characteristics through an expanded full band Monte Carlo particle-based simulator self-consistently coupled to an energy balance heat equation for phonons. The accurate temperature profiles obtained for the acoustic and optical phonon modes, showed that the location of the hot spot in the channel is not at the peak of the electric field, but it is shifted towards the drain up to 34nm. Also, the modeled IdVdsVgs space is improved as a result of including the self-heating effects, which modify the charge transport in the active layer of the device through the temperature dependence of the scattering mechanisms considered in the simulations.
Reexamination of Mood-Mediation Hypothesis of Background-Music-Dependent Effects in Free Recall

The present study reexamined the mood-mediation hypothesis for explaining background-music-dependent effects in free recall. Experiments 1 and 2 respectively examined tempo- and tonality-dependent effects in free recall, which had been used as evidence for the mood-mediation hypothesis. In Experiments 1 and 2, undergraduates (n = 75 per experiment) incidentally learned a list of 20 unrelated words presented one by one at a rate of 5 s per word and then received a 30-s delayed oral free-recall test. Throughout the study and test sessions, a piece of music was played. At the time of test, one third of the participants received the same piece of music with the same tempo or tonality as at study, one third heard a different piece with the same tempo or tonality, and one third heard a different piece with a different tempo or tonality. Note that the condition of the same piece with a different tempo or tonality was excluded. Furthermore, the number of sampled pieces of background music was increased compared with previous studies. The results showed neither tempo- nor tonality-dependent effects, but only a background-music-dependent effect. Experiment 3 (n = 40) compared the effects of background music with a verbal association task and focal music (only listening to musical selections) on the participants’ moods. The results showed that both the music tempo and tonality influenced the corresponding mood dimensions (arousal and pleasantness). These results are taken as evidence against the mood-mediation hypothesis. Theoretical implications are discussed.

Bill Share - Capacity Planning and Management

Management of the information technology of today’s enterprise must address the twofold challenge of meeting customer expectations on one hand while staying competitive by controlling IT costs on the other hand. Round-the-clock performance, availability and security are the crucial indicators of quality of service for mission critical web applications. Tradeoffs are necessary to accommodate hardware limitations, quality issues and budget concerns. Capacity planning techniques are essential for ensuring the quality of web services within budget. In particular, with multi-tier architectures becoming industry standards, it is important to design effective and accurate performance prediction models under an enterprise production environment with a real workload mix. The primary objective of the research described in this thesis is to understand the techniques for capacity planning within an enterprise organization when a significant new service is integrated. We first propose a new online service component named Bill Share and then describe how this service integrates with other existing web services of the enterprise. To provide a new service that results in an increase in sales resulting in further profits. We then perform capacity modeling with different hardware models and evaluate the performance metrics against a similar bill tracking web application. We then build an application prototype to validate response times, availability and server utilization’s predicted by our model.
SEC’s 2010 Release on Climate Change: Shifting from Voluntary to Mandatory Climate Change Disclosure

ABSTRACT Although the United States Congress has not federally mandated climate change policies, the Securities and Exchange Commission (SEC) has instituted climate change disclosure policies. As part of this policy it requires that firms making certain voluntary climate change disclosures also provide them in their mandatory annual filings with the SEC. Using a sample of companies that participate in Regional Greenhouse Gas Initiative and are therefore major generators of carbon emissions we found that for these firms a small portion of them still provide voluntary climate change disclosures that are not included in their mandatory SEC annual filings. These disclosures are mainly concerned with their environmental reputation or with capital expenditures for climate change. Furthermore, we find that voluntary climate change disclosures after the February 2010 SEC release date significantly decreased whereas mandatory disclosure significantly increased, suggesting that the SEC release had a dampening effect on voluntary disclosures.
Interdependencies across Sovereign Bond Credit Default Swap Markets

This paper investigates the dependence structures between sovereign credit default swap (CDS) spreads of fifteen countries for the period of January 2005-July 2015. We employ copula approach to conduct this analysis as it enables us to analyze dependence structure separately from univariate characteristics of the series and to model a richer dependence structure by utilizing a broad range of distribution functions. Our results demonstrate that dependence structures are similar among majority of the pairs and in most of the countries lower and upper tail dependencies show similar behavior. This result contradicts with the findings that asset prices tend to move together more during times of negative shocks. The second finding of the paper is that sovereign CDS spreads, adjusted for global risk aversion, show positive dependence for all country pairs yet with varying degrees. There are country groups showing high average and tail dependence. Dependence between most of the emerging markets is found to be high on average yet it is low between emerging market and advance economies. We argue that similarities in credit quality gauged by credit ratings and carry trade returns of international investors may lead to the observed interdependence structures of CDS spreads.
Energy and performance trade-off in nanophotonic interconnects using coding techniques

Nanophotonic is an emerging technology considered as one of the key solutions for future generation on-chip interconnects. Indeed, this technology provides high bandwidth for data transfers and can be a very interesting alternative to bypass the bottleneck induced by classical NoC. However, their implementation in fully integrated 3D circuits remains uncertain due to the high power consumption of on-chip lasers. However, if a specific bit error rate is targeted, digital processing can be added in the electrical domain to reduce the laser power and keep the same communication reliability. This paper addresses this problem and proposes to transmit encoded data on the optical interconnect, which allows for a reduction of the laser power consumption, thus increasing nanophotonics interconnects energy efficiency. The results presented in this paper show that using simple Hamming coder and decoder permits to reduce the laser power by nearly 50% without loss in communication data rate and with a negligible hardware overhead.
From qMade in Chinaq to qCopy from Chinaq: Can Chinese Bicycle-sharing Lead the World Trend?

The development of “Internet plus” economy has given rise to a new era of “Chinese style sharing and all-win”, and people all the world think it’s breathtaking. Especially bicycle-sharing enlarges sharply in China and sweeps the world rapidly. Based on the research of predecessors, this paper analyzed the business model of bicycle-sharing in China and current development abroad. By this study, we can analyze the experience and deficiencies in the international development of shared bicycles and explore whether Chinese bicycle-sharing can lead the world trend. And this paper makes three suggestions for the Chinese bicycle-sharing to get out of the country and two more for the bicycle enterprises abroad to develop rapidly. In addition, it can provide a reference for the future development of the sharing economy. Keywords—Chinese bicycle-sharing; Sharing economy; Business model; Created in China; Copy from China
Psychological Problems of Patients with Cleft Lip and Palate: Discussion Paper

Psychology has been described as common sense dressed up in statistics. It is a definition that I am not entirely happy with, because I am wary of invoking common sense. Common sense, after all, tells us that the world is flat, it's very obvious that the world is flat: you only have to look at it and the idea that it could be anything but flat is nonsensical. Common sense tells us that anyone with a severe facial deformity, or indeed a mild facial deformity, should have some kind of psychological hang-up and if to that is added a speech defect, then they are well on the way towards emotional disturbance from birth. The facts are different. There is a contradiction within the literature on facial deformity. On the one hand, one can read what seems quite compelling evidence to suggest that any kind of facial disfigurement or deformity, plus a speech defect, is likely to be psychologically damaging. On the other hand, there is a body of experimental evidence which contradicts that. In this paper I look at both sides of the argument and then come to some resolution of the two positions. To start with the arguments supporting the notion that a facial deformity must produce emotional disturbance.
Application of conditional value at risk for credit risk optimization

The article is dedicated to theÂ optimization of credit risk through the application of Conditional Value at Risk (CVaR). CVaR is a risk measure, the expected loss exceeding Value-at-Risk and is also known as Mean Excess, Mean Shortfall, or Tail VaR. The link between credit risk and the current financial crisis accentuates the importance of measuring and predicting extreme credit risk. Conditional Value at Risk has become an increasingly popular method for measurement and optimization of extreme market risk. The use of model can regulate all positions in a portfolio of financial instruments in order to minimize CVaR subject to trading and return constraints at the same time. The credit risk distribution is created by Monte Carlo simulations and the optimization problem is solved effectively by linear programming. We apply these CVaR techniques to the optimization of credit risk on portfolio of selected bonds.

Some Practical Experiences in Data Governance

If managed correctly, data can become an organization's most valuable asset, helping it to remain competitive and agile, to proactively meet customer needs, and to keep costs in check. Companies and government organizations of all sizes are striving to manage data as an enterprise asset, to be shared and reused across multiple software applications and systems, business processes, and users throughout the organization. They're finding that they need to establish standards, policies, and processes for the usage, development, and management of data. They recognize that creating the right organizational structure and developing the technology infrastructure to support the governance of their data is also critical.
Efficiency of direct driven hydraulic drive for non-road mobile working machines

As answer for tendencies for compact and powerful solution for electro-hydraulic systems, this paper investigates directly driven hydraulic setup for non-road mobile machinery (NRMM) application. The control of the system is implemented directly with a servo motor drive without conventional hydraulic control valves, which allows accurate control and regeneration. Speed of the double-acting cylinder is determined by in-coming oil flow from the pump, out-coming flow to the hydraulic motor and angular speed of the electric motor. The paper provides a detailed analysis of the system and an evaluation of setup usage for NRMM application. Finally, possible improvements of the suggested system are discussed.
Energy consumption optimization of parallel applications with Iterations using CPU frequency scaling. (Optimisation de la consommation énergétique des applications parallèles avec des itérations en utilisant réduisant la fréquence des processeurs)

In recent years, green computing has become an important topic in the supercomputing research domain. However, the computing platforms are still consuming more and more energy due to the increase in the number of nodes composing them. To minimize the operating costs of these platforms many techniques have been used. Dynamic voltage and frequency scaling (DVFS) is one of them. It can be used to reduce the power consumption of the CPU while computing, by lowering its frequency. However, lowering the frequency of a CPU may increase the execution time of the application running on that processor. Therefore, the frequency that gives the best trade-off between the energy consumption and the performance of an application must be selected.This thesis, presents the algorithms developed to optimize the energy consumption and theperformance of synchronous and asynchronous message passing applications with iterations runningover clusters or grids. The energy consumption and performance models for each type of parallelapplication predicts its execution time and energy consumption for any selected frequency accordingto the characteristics of both the application and the architecture executing this application.The contribution of this thesis can be divided into three parts: Firstly, optimizing the trade-offbetween the energy consumption and the performance of the message passing applications withsynchronous iterations running over homogeneous clusters. Secondly, adapting the energy andperformance models to heterogeneous platforms where each node can have different specificationssuch as computing power, energy consumption, available frequency gears or network’s latency andbandwidth. The frequency scaling algorithm was also modified to suit the heterogeneity of theplatform. Thirdly, the models and the frequency scaling algorithm were completely rethought to takeinto considerations the asynchronism in the communication and computation. All these models andalgorithms were applied to message passing applications with iterations and evaluated over eitherSimGrid simulator or Grid’5000 platform. The experiments showed that the proposed algorithms areefficient and outperform existing methods such as the energy and delay product. They also introducea small runtime overhead and work online without any training or profiling.
Effects of Occupational Safety and Health Hazards’ Exposure on Work Environment in the Water Service Industry within Kisumu County - Kenya

The study sought to determine effects of exposure to occupational safety and health hazards on work environment in the Kenyan Kisumu County Water Service industry. The study utilized a descriptive research design. The target population consisted of employees of Kisumu Water and Sewerage Company (KIWASCO) and Lake Victoria South Water Service Board (LVSWSB) working in water treatment works, waste water treatment plants and construction sites. Questionnaires were used to obtain primary data; that were analyzed using quantitative techniques. Standard deviation was adapted to measure disparity for the likert-scale questionnaires. The entire hypothesis was tested at 95% confidence level. Risk Severity rating was then done for Biological, Chemical, Ergonomics, Physical, Psychological and Safety risks. Results reveal that employees working in the water service industry in Kisumu County are exposed to hazards and risks. Both Biological and Chemical risks are high or major among staff in the water sector. While Ergonomics, Physical and Psychological risks are minor, they are likely to happen in the sector. We recommend that the management of water service industry immediately institute measures to avoid the Biological and Chemical risks, while adequate preparedness should be put in place against other risks.
Design and Pricing of Chinese Contingent Convertible Bonds

Abstract The financial crisis since 2007 has highlighted the fragility of the banking system. To address this deficiency, the Basel committee has agreed upon Basel III which consists of reinforcing banks’ capital through new regulatory requirements. Raising additional funds by issuing common equity would lead to a significant cost for banks. Facing the problem, regulators came up with the concept of contingent capital. Contingent convertible (Coco) bonds have been the topic as both a solution to the “too big to fail” problem and a measure by which financial institutions can save themselves. In this paper we first give the introduction of Coco bonds, then present the design of Chinese Coco bonds and pricing Coco bonds through an equity derivative approach as well as sensitivity analysis based on B-S-M hypothesis. Considering that the stock return follows fat-tail distribution, this paper uses Heston stochastic volatility model to price Coco bonds. Finally we give some proposals for developing Coco bonds market in China.
Wine Processing: A Critical Review of Physical, Chemical, and Sensory Implications of Innovative Vinification Procedures

Wine is one of the most popular alcoholic beverages in the world, although it is mainly consumed in European and South American countries. Several thousand years have passed since the product of grape fermentation was accidentally discovered. Over the last 100–150 years, winemaking has been completely revolutionized in terms of procedures and equipment. This work is aimed to give a comprehensive overview of the consolidated use of winemaking innovations that are still in the development stage or already applied to commercial products. Their effects on physical, chemical, and sensory characteristics of wines will also be discussed in comparison with the consolidated vinification procedures.
Mixer Cell formation during dorsal closure: A new developmental model of JNK-dependent natural cell reprogramming in Drosophila

What triggers a differentiated cell to naturally change its cell fate? Cell reprogramming is a rare and intriguing phenomenon, from a developmental point of view. It has been mostly involved in boundary sharpening during development, tissue regeneration and cancer. Developmental models of the understanding of pathology-related cell reprogramming are yet to be established. Here we comment on the recently discovered "Mixer Cells" undergoing highly stereotyped developmental reprogramming during Drosophila epidermal morphogenesis. The JNK signaling pathway, which is involved in regenerative cell reprogramming, is essential to Mixer Cell formation. Thus the Mixer Cell model may provide a link between developmental cell reprogramming and regeneration.
Resource‐based adaptive divergence in the freshwater fish Telmatherina from Lake Matano, Indonesia

Adaptive radiations are an important source of biodiversity, but resolving which ecological pressures seed these processes in natural systems remains difficult. Here the adaptive radiation among Telmatherina, a genus of freshwater fish endemic to an ancient lake in central Sulawesi, Indonesia, was examined to determine its causal root. We demonstrate that all Telmatherina in this lake can be categorized into three lineages each possessing specialized skull shapes and pharyngeal jaw bones allowing them to exploit different resources. These data demonstrate a natural example of how resource partitioning has likely initiated adaptive radiation in a resource limited environment.
Hypermethylation of ASC / TMS 1 Is a Sputum Marker for Late-Stage Lung Cancer

DNA hypermethylated gene promoter sequences are extremely promising cancer markers. Their use for risk assessment, early diagnosis, or prognosis depends on the timing of this gene change during tumor progression. We studied this for the proapoptotic gene ASC/TMS1 in lung cancer and used the findings to develop a sputum marker. ASC/TMS1 protein levels are reduced in all lung cancer types (30 of 40; 75%) but not in 10 preinvasive lesions. Hypermethylation of ASC/TMS1 is also associated with invasive cancers (41 of 152 or 27.0% of all lung cancer types) with variation in incidence between histopathologic types including 32.1% (26 of 81) of adenocarcinomas, 13.2% (7 of 53) of squamous cell carcinomas, 38.5% (5 of 13) of large-cell carcinomas, and 60% (3 of 5) of small-cell lung cancers. The hypermethylation is particularly correlated with late tumor stages being present in only 14% of stage I but 60% of later-stage tumors. The incidence of ASC/TMS1 hypermethylation in sputum DNA fully mimics the tissue findings being present in only 2% (2 of 85) of high-risk, cancerfree smokers, 15% (3 of 18) of patients with stage I non–smallcell lung cancer (NSCLC), but 41% of patients with stage III NSCLC (18 of 44), including 56% (10 of 18) of those with adenocarcinoma. Importantly, sputum is positive for this marker in 24% (10 of 42) of very high risk, clinically cancerfree individuals previously resected for stage I NSCLC. Thus, hypermethylation of ASC/TMS1 is a marker for late-stage lung cancer and, in sputum, could predict prognosis in patients resected for early-stage disease. (Cancer Res 2006; 66(12): 6210-8)
