Exploiting Heterogeneity for Tail Latency and Energy Efficiency

Interactive service providers have strict requirements on high-percentile (tail) latency to meet user expectations. If providers meet tail latency targets with less energy, they increase profits, because energy is a significant operating expense. Unfortunately, optimizing tail latency and energy are typically conflicting goals. Our work resolves this conflict by exploiting servers with per-core Dynamic Voltage and Frequency Scaling (DVFS) and Asymmetric Multicore Processors (AMPs). We introduce the Adaptive Slow-to- Fast scheduling framework, which matches the heterogeneity of the workload–a mix of short and long requests–to the heterogeneity of the hardware– cores running at different speeds. The scheduler prioritizes long requests to faster cores by exploiting the insight that long requests reveal themselves. We use control theory to design threshold-based scheduling policies that use individual request progress, load, competition, and latency targets to optimize performance and energy. We configure our framework to optimize Energy Efficiency for a given Tail Latency (EETL) for both DVFS and AMP. In this framework, each request self-schedules, starting on a slow core and then migrating itself to faster cores. At high load, when a desired AMP core speed s is not available for a request but a faster core is, the longest request on an s core type migrates early to make room for the other request. Compared to per-core DVFS systems, EETL for AMPs delivers the same tail latency, reduces energy by 18% to 50%, and improves capacity (throughput) by 32% to 82%. We demonstrate that our framework effectively exploits dynamic DVFS and static AMP heterogeneity to reduce provisioing and operational costs for interactive services.

Advertising and media literacy : young people and their understanding ofthe world of advertising in Australia and Thailand

This thesis demonstrates that Thai, Thai-Australian, and Asian international participants have a stronger knowledge of advertising industry operation compared with Australian participants. Thai and Thai-Australian participants were more sceptical of the rhetorical claims of advertising and aware of global branding techniques. Differences are also apparent in readings of gender and sexuality in advertising. Australian participants focused more on questions of gender inequality, while Thai participants moralised more about sexuality. Thai participants were also more concerned with the ethics of over-consumption. Australian participants exhibited characteristics of low-context cultures and often used a direct style to demonstrate their knowledge of the media. Thai participants used characteristically elaborate and indirect styles, typical of high-context readings of the media.

Detecting potentially compromised credentials in a large-scale production single-signon system

Abstract : We posit that potentially compromised credentials are detectable by analyzing the system artifacts of a large-scale production, single-signon system. With permission from the Defense Manpower Data Center, we analyze a year s worth of system artifacts produced by the Department of Defense Self-Service Logon system. Using industry standard tools and descriptive statistics we develop a repeatable process that identifies potentially compromised credentials. We look for characteristics that coincide with compromised credentials and evaluate our approach by obtaining the ground truth on several of the credentials we identify.
III.—On a New Plesiosaur from the Oxford Clay

This Plesiosaur was collected from the Oxford Clay at Peterborough by A. N. Leeds, Esq. , F.G. S. , and was acquired for the Hunterian Museum, Glasgow University, by Professor J. W. Gregory. The specimen has many striking resemblances to Cryptocleidus oxoniensis, but detailed examination showed that it could not belong to that species, and the differences existing in the paddle, shoulder-girdle, number of vertebræ, and conditions of ossification are such that it cannot be retained in that genus as now defined. The paddle closely resembles that of Tricleidus, but the shoulder-girdle alone is sufficient to prevent the inclusion of the specimen in that genus. It seems advisable to create a new genus, and as it may be some time beforea full description can be published a preliminary account is here given.
Na secretion rate increases proportionally more than the Na reabsorption rate with increases in sweat rate

Buono MJ, Claros R, DeBoer T, Wong J. Na secretion rate increases proportionally more than the Na reabsorption rate with increases in sweat rate. J Appl Physiol 105: 1044–1048, 2008. First published July 24, 2008; doi:10.1152/japplphysiol.90503. 2008. —The purpose of this study was to measure the in vivo Na secretion and Na reabsorption rates of the human eccrine sweat gland with increases in sweat rate. Such data should help to elucidate the physiological mechanism responsible for the previously reported linear relationship between increases in sweat rate and Na concentration in sweat. On 5 days, each subject (n 10) completed a 30-min exercise bout in an environmental chamber set at 35°C and 40% relative humidity. The intensity for the five exercise bouts in the heat was set to approximate 50, 60, 70, 80, and 90% of age-predicted maximum heart rate. Forearm sweat samples and capillary blood samples were collected during each of the five 30-min exercise bouts. The sweat and blood samples were analyzed for Na concentration in sweat and serum, which were used to calculate the rate of Na secretion and Na reabsorption. The mean correlation between sweat rate and Na concentration in sweat was found to be r 0.73. Within the sweat rate range of the present study, both Na secretion rate and Na reabsorption rate increased linearly; however, the Na secretion rate increased almost twice as fast (slope 141 vs. 80). Thus the rate at which Na escaped reabsorption increased with increases in sweat rate and was significantly (P 0.05) correlated to the Na concentration in sweat (mean r 0.90). Such results strongly suggest that the physiological mechanism responsible for the previously reported linear increase in Na concentration in sweat seen with increases in sweat rate is that the Na secretion rate increases proportionally more than the Na reabsorption rate.
Netrin-4 Promotes Glioblastoma Cell Proliferation through Integrin Β 4 Signaling 1,2

Netrin-4 is a laminin-related secreted molecule originally found to have roles in neuronal axon migration. Recent studies have indicated that netrin-4 also participates in the development of nonneural tissues and modulates tumor cell proliferation and tumor metastasis. Here we have explored the functions and molecular mechanisms of netrin-4 in glioblastoma multiforme. The suppression of netrin-4 expression in glioblastoma cell lines significantly reduced cell proliferation and motility and increased serum deprivation–induced apoptosis. Using tandem affinity purification combined with protein identification by mass spectrometry, we found that integrin β 4 interacts with netrin-4 and that it mediates mitogenic effects as well as AKT and mammalian target of rapamycin phosphorylation induced by netrin-4. Interestingly, netrin-4 acted as an inhibitor of cell proliferation in integrin β 4 –silenced glioblastoma cells, and high concentrations of netrin-4 reduced cell proliferation. The negative effects of netrin-4 on proliferation were mediated by UNC5B. Analysis of more than 400 primary tumors from The Cancer Genome Atlas repository revealed that the expression of netrin-4 is significantly downregulated in glioblastoma and that the reduced expression is linked to poor patient survival time. The expression of integrin β 4 is increased in glioblastoma, and it predicts poor patient survival time. Current results illustrate a novel mechanism for glioma progression, where glioma cells reduce netrin-4 expression to decrease its inhibitory effects. In parallel, the expression of integrin β 4 is upregulated to sensitize the cells to low concentrations of netrin-4 for maintaining cell proliferation. Introduction Netrins (NTNs) are laminin-related secreted molecules with roles in em-bryogenesis and tumor development. So far, five mammalian members have been identified in this family: netrin-1,-3,-4,-G1, and-G2 [1]. Netrin-1 (NTN1) has been defined as a neuronal guidance cue displaying both attractive and repulsive roles for neuronal cells and axons. Both netrin receptor deleted in colorectal cancer (DCC) and netrin receptor uncoordinated 5 (UNC5s) are major receptors mediating the attractive and repulsive effects of NTN1 [1,2]. Similar to the dual role in axon guidance, the biphasic function of NTN1 appears in the development of the vasculature, reflected by contrasting results in various studies [3–6]. NTN1 can also modulate the development of many other tissues such as the mammary gland, the pancreas, and the lung [7–9]. During tumor progression, NTN1 acts as a survival factor for numerous types of tumor cells during tumor progression through a " dependence-receptor " mechanism [10]. Another member of the NTN family, netrin-4 (NTN4), is expressed …
Evaluation of autoconversion schemes in a single model framework with satellite observations

We examined the performance of autoconversion (mass transfer from cloud water to rainwater by the coalescence of cloud droplets) schemes in warm rain, which are commonly used in general circulation models. To exclude biases in the different treatment of the aerosol‐cloud‐precipitation‐radiation interaction other than that of the autoconversion process, sensitivity experiments were conducted within a single model framework using an aerosol‐climate model, MIROC‐SPRINTARS. The liquid water path (LWP) and cloud optical thickness have a particularly high sensitivity to the autoconversion schemes, and their sensitivity is of the same magnitude as model biases. In addition, the ratio of accretion to autoconversion (Acc/Aut ratio), a key parameter in the examination of the balance of microphysical conversion processes, also has a high sensitivity globally depending on the scheme used. Although the Acc/Aut ratio monotonically increases with increasing LWP, significantly lower ratio is observed in Kessler‐type schemes. Compared to satellite observations, a poor representation of cloud macrophysical structure and optically thicker low cloud are found in simulations with any autoconversion scheme. As a result of the cloud‐radiation interaction, the difference in the global mean net cloud radiative forcing (NetCRF) among the schemes reaches 10 Wm−2. The discrepancy between the observed and simulated NetCRF is especially large with a high LWP. The potential uncertainty in the parameterization of the autoconversion process is nonnegligible, and no formulation significantly improves the bias in the cloud radiative effect yet. This means that more fundamental errors are still left in other processes of the model.
ATOVis—a Visualization Tool for the Detection of Financial Fraud

Fraud detection is related to the suppression of possible financial losses for institutions and their clients. It is a task of high responsibility and, therefore, an important phase of the decision-making chain. Nowadays, experts in charge base their analysis on tabular data, usually presented in spreadsheets and seldom supplemented with simple visualizations. However, this type of inspection is laborious, time-consuming, and may be of little use for the analysis and overview of complex transactional data. To aid in the inspection of fraudulent activities, we develop ATOVis—a visualization tool that enables a fast analysis and detection of suspicious behaviours. We aim to ease and accelerate fraud detection by providing an overview of specific patterns within the data, and enabling details on demand. ATOVis focuses on applying visualization techniques to the Finance domain, specifically e-commerce, contributing to the state-of-the-art as the first visualization tool primarily specialised in Account Takeover (ATO) patterns. In particular, the present paper incorporates: a task abstraction for detecting of a specific financial fraud pattern—ATO; two models for the visualization of ATO; and a multiscale timeline to enable an overview of the data. We also validate our tool through user testing, with experts in fraud detection and experts from other fields of data science. Based on the feedback provided by the analysts, we could conclude that ATOVis is an efficient and effective tool in detecting specific patterns of fraud which can improve the analysts’ work.
Instantaneous real-time cycle-slip correction for quality control of GPS carrier-phase measurements

: This paper proposes a new cycle-slip correction method that enables instantaneous correction (i.e., using only the current epoch's GPS carrier-phase measurements) at the data quality control stage. The method was originally developed for real-time applications that require consistent high-precision positioning results with the carrier-phase measurements at a 10 Hz data rate. The approach includes (1) two parameters for generating and filtering cycle-slip candidates, and (2) a validation procedure that authenticates correct cycle-slip candidates. Compared with conventional approaches using carrier phases and pseudoranges, the approach does not require a smoothing or filtering process to reduce observation noise. Therefore, it is possible to implement the approach in real-time applications without undue complexity. Simulation tests were conducted to confirm the performance of the approach under worst-case scenarios. Test results for a variety of situations, including static and kinematic modes, short-baseline and long-baseline situations, and low and high data rates, are presented.

MHD natural convection in saturated porous media with heat generation/absorption and thermal radiation: closed-form solutions

The present work is devoted to the free convection flow occurring about a heated vertically stretching permeable surface placed in a porous medium under the influence of a temperature dependent internal heat generation or absorption. There are volume radiative heat sources in the fluid and the system is permeated by a uniform magnetic field. It is shown that the governing equations are reducible to a self-similar nonlinear ordinary differential equation of third order whose solutions are constructed analytically in the purely exponential series form. Under special circumstances, closed-form solutions are available which clearly indicate the existence of dual natural convection solutions. Otherwise, analytical solutions are still possible which are shown to be computed from an elegant algorithm without a need to invoke any numerical means. Exact solutions demonstrate, in physical insight that, in the presence of a heat sink absorbing the temperature from the porous medium increases the rate of heat transfer from the wall, whereas a heat source mechanism will surely overheat the system during the wall heating process, resulting in poor heat transfer rates. The presented exact solutions are beneficial for investigation of free convection phenomena in different geometries taking into account more complex physical features in higher dimensions.

Personalized Medicine in the Era of Genomics

Personalized medicine is a model that aims at customizing healthcare and tailoring medicine according to an individual`s genetic makeup. It classifies individuals that differ in their susceptibility to a particular disease or response to a particular treatment into subpopulations based on individual’s unique genetic and clinical information along with environmental factors. The completion of Human Genome Project and the advent of high-throughput genome analysis tools has helped in building and strengthening this model. There lies a huge potential in the implementation of personalized medicine to significantly improve the clinical outcomes; however, its implementation into clinical practice remains slow and is a matter of concern. This chapter aims at acquainting readers with the underlying concepts and components of personalized medicine supplemented with some disease-based case studies, discussing challenges and recent advancements in the implementation of the model of personalized medicine.
Stock Price Reactions to the Information and Bias in Analyst-Expected Returns

This paper provides evidence that the market does not efficiently incorporate expected returns implied by analyst price targets into prices. I use a novel decomposition to extract information and bias components from these analyst-expected returns and develop an asset pricing framework that helps interpret price reactions to each component. A one-standard-deviation increase in the information (bias) component is associated with a five (one) percentage point increase in announcement-month returns. The positive reaction to bias implies the market does not fully debias analyst-expected returns before incorporating them into prices. Prices overreact to bias and reverse their initial reaction within three to six months. Prices underreact to information and returns drift an additional one percentage point beyond their initial reaction in the following 12 months. Announcement-window returns forecast future returns, which provides model-free evidence of underreaction, and that underreaction dominates overreaction. Trading against underreaction generates average monthly returns of 1.12% with a Sharpe ratio of 1.08, and the returns survive controlling for exposure to many standard factors.
Emerging business models and strategies for mobile middleware technology providers: A reference framework

As Mobile Network Operators are turning their attention to value added services, the need for innovative technology platforms designed for mobile digital contents management becomes evident. Such phenomenon is enhancing the strategic relevance of the “Mobile Middleware Technology Providers”(MMTPs) within the Mobile Content Value Network. The purpose of this paper is to explore which are the most critical choices to be made at a business model design level for a MMTP, to understand how these parameters are interrelated and can be combined to give rise to differential business models, and finally to delineate what are the most significant underlying “strategic patterns” driving the first steps of MMTPs activity within the Mobile Content competitive arena. The research relies on the adoption of a multiple case studies methodology: through 72 semi-structured interviews, 24 MMTPs were analyzed.The research findings show that some key business model parameters identified by the existing literature can be applied to MMTPs’ business model design process, while others were missing or not made explicit. Moreover, three noteworthy business models currently adopted by MMTPs – “Pure Play”, “Full Asset” and “Platform & Content Management” business models – were identified, associated respectively to three underlying strategic patterns – “stay on core”, “grow, wait and see” and “aggressive downstream”.
Stochastic tunneling in DBI inflation

We reconsider the dynamics of stochastic or thermal tunneling in theories with non-minimal kinetic terms such as DBI inflation. A local description of the tunneling process gives results consistent with the standard Hawking-Moss tunneling. This result is under perturbative control away from the regime of 'relativistic eternal inflation. ' A global description, using the stochastic inflation method, demonstrates that the tunneling process becomes strongly coupled whenever the sound speed of the tunneling trajectory departs sufficiently from unity. We argue that these two very different perspectives are nevertheless consistent, and may imply the existence of a simple resummation of the strongly coupled interactions of the field.
Study on Seedling Adaptability of Abies chensiensis

Through seeding test on field condition under different of altitude,lighting,seedbed type and soil thickness,as well as seed germination and seedling survival being compared among provenances,the adaptability of Abies chensiensis seed and seedling were studied in natural environment.The results showed that in natural environment the seed germination rate of A.chensiensis was only 17.7%,which was less than half of its germination rate(36%) in laboratory.Altitude,lighting,seedbed type,soil thickness and seed provenances all had various effects on seed germination,seedling survival and growth of A.chensiensis. In practice,the rejuvenation of A.chenesiensis should follow the principle of favored tree species for suitable sites and optimal provenances be used.
