ReDAL: An Efficient and Practical Request Distribution Technique for Application Server Clusters

Modern Web-based application infrastructures are based on clustered multitiered architectures, where request distribution occurs in two sequential stages: over a cluster of Web servers and over a cluster of application servers. Much work has focused on strategies for distributing requests across a Web server cluster in order to improve the overall throughput across the cluster. The strategies applied at the application layer are the same as those at the Web server layer because it is assumed that they transfer directly. In this paper, we argue that the problem of distributing requests across an application server cluster is fundamentally different from the Web server request distribution problem due to core differences in request processing in Web and application servers. We devise an approach for distributing requests across a cluster of application servers such that the overall system throughput is enhanced, and load across the application servers is balanced.
Decreased Polyunsaturated Fatty Acid Content Contributes to Increased Survival in Human Colon Cancer

Among diet components, some fatty acids are known to affect several stages of colon carcinogenesis, whereas others are probably helpful in preventing tumors. In light of this, our aim was to determine the composition of fatty acids and the possible correlation with apoptosis in human colon carcinoma specimens at different Duke's stages and to evaluate the effect of enriching human colon cancer cell line with the possible reduced fatty acid(s). Specimens of carcinoma were compared with the corresponding non-neoplastic mucosa: a significant decrease of arachidonic acid, PPARα, Bad, and Bax and a significant increase of COX-2, Bcl-2, and pBad were found. The importance of arachidonic acid in apoptosis was demonstrated by enriching a Caco-2 cell line with this fatty acid. It induced apoptosis in a dose- and time-dependent manner via induction of PPARα that, in turn, decreased COX-2. In conclusion, the reduced content of arachidonic acid is likely related to carcinogenic process decreasing the susceptibility of cancer cells to apoptosis.
Cosy Cognitive Systems for Cognitive Assistants Learning and Recognition of Complex Human Actions

Executive Summary This deliverable concerns the third objective of WP5, which is to develop a learning and recognition algorithm for complex actions. We have extended the factored-HMM representation of manipulation actions developed in Year 2 by another layer of dynamic models of goals, in which details of manipulation movements are abstracted away. The focus of work in Year 3 is to model the dynamics of human intention that results in the observed human complex behaviour. This report is a revised and extended version of the report submitted in Year 2, and contains new analysis results. • Two key capabilities: We identify two key capabilities for a system to understand a complex human behaviour. The first capability is to learn normal behaviour that allows induction of the agent's goals from partial or noisy observation. The second is to be able to attribute any deviations from normal behaviour to the background knowledge (hidden) or other differentiating scene features (observable). Achieving these capabilities requires a representation that not only encodes the dynamics of the scene, but also allows information about other agents' beliefs, plans and intentions to be integrated. Human complex behaviour is represented by a hierarchical, factorized hidden Markov models (factored-HMMs) as shown in Figure 1. It consists of two levels of HMMs. The nodes of HMM at the lower level are factorized into manipulation types (h) and object states (o) which produces observable visual features f h and f o , respectively. The links between nodes represent the dependencies in human decision process. At time t, hand movement h t depends on o t−1 and g t , which models the goal of the acting agent. Complex manipulation is considered to be caused by the agent's evolving manipulation goals, which are modeled by another layer of HMMs. To understand complex behaviour, the observer needs to represent the agents' prior knowledge about goals and how they may evolve. • Modeling evolving goals: We suggest two candidate models based on goal switching and goal composition. " Goal switching " is a process whereby one manipulation action is switched into another manipulation action, and can be used to account for sequences of actions. " Complex goal composition " is a process whereby a goal is augmented by sub-goals to account for deviations from normal behaviour. Factored-HMMs have been extended to take into account evolving goal models, and used to segment input video streams into …
A new quality of service metric for hard/soft real-time applications

Real-time applications often have mixed hard and soft deadlines, can be preempted subject to the cost of context switching or the restart of computation, and have various data dependency. The simple but widely used task completion ratio, as the quality of service (QoS) metric, does not capture these characteristics and can not reflect user perceived QoS well. In this paper, we propose a new quantitative QoS metric, which is based on task completion ratio but differentiates hard and soft deadlines and models data dependency as well. Basically, it assigns different weights to hard and soft deadline tasks, penalizes late soft task completion, and measures the tasks affected by any dropped tasks. We apply popular online schedulers such as EDF (earliest deadline first), FCFS (first come first serve), and LETF (least execution time first), on a set of simulated MPEG movies at the-frame level and for each application compare the new QoS measurement, traditional completion ratio with the "real" completion ratio which considers the number of correctly decoded frames and has been mapped to the user perceived QoS well. Experimental results show that our proposed QoS metric can reflect real life QoS much better than the traditional one.
Teaching “Quanti” – Lessons from French Experiences in Sociology and History

The paper’s main objective is to reflect, from both a sociological and a historiographical perspective, on how to use and how to teach quantitative methods in the social sciences. French and American social scientists, whether apprentices or confirmed, often encounter during their work a crucial need to use quantitative methods. But which methods do each favor? And how to teach these methods? In strongly varying national and disciplinary contexts, what are the directions taken by the revival of interest for quantitative methods? Comparing current pedagogical practices may be a heuristic way to raise crucial questions about historiographical uses of quantitative methods, and give way to a cautious advocacy of reflective uses of quantitative methods in the social sciences.
Nuclear activity in nearby galaxies - Mid-infrared imaging with the VLT

Aims. Dust enshrouded activity can be studied ideally by mid-infrared (MIR) observations. To explore the active galactic nuclei (AGN) versus star forming origin of the nuclear MIR emission of galaxies, observations of high spatial resolution are required. We report on 11.3 μm observations with VISIR at the VLT, which reach 0.35 �� spatial resolution (FWHM). Methods. During the scientific verification of VISIR, we observed a sample of 36 nearby galaxies with a range of optically classified nuclear activity: 17 black hole driven AGN, 10 starbursts (SB), and 9 quiescent spirals. Results. 16 objects out of 17 AGN are detected and unresolved, 5 out of 10 SB are detected and resolved with structured emission up to a few arcsec, while for 5 targets out of 10 SB and all 9 quiet nuclei low upper limits are provided. The morphology of the resolved SB nuclei is similar to that observed at radio frequencies. The compactness of AGN and the extent of SB nuclei is consistent with the predictions of radiative transfer models and Spitzer spectra observed at much lower spatial resolution than with VISIR. We introduce the nuclear MIR surface brightness, S , as a quantitative measurement for AGN and SB activity. Although one is unable to distinguish between AGN and SB activity using the nuclear MIR surface brightness derived from 4 m class telescopes, our data indicate that, out to a distance of 100 Mpc, the MIR surface brightness acquired by 8 m class telescopes can differentiate AGN from SB behavior.
Empirical Analysis of Android Apps Permissions

Android applications or apps are taking the smart phones industry to a new level. Smart phone users can do most of their everyday tasks using the various types of applications offered in the Android Play Store. Generally, prior to installation of the apps, users need to agree on the permissions requested by the apps, they are not given any other option. Essentially, users may not aware on some security issues that may arise from the permissions. Some apps request the right to manipulate sensitive data, such as GPS location, photos, calendar, contact, email and files. In this paper, we explain the sources of sensitive data, what the malicious apps can do to the data, and apply the empirical software engineering analysis to find the factors that could potentially influence the permissions in Android apps. In addition, we also highlight top ten most implemented permissions in Android apps.
Doing away with the Viterbi approximation

In this paper, we investigate the use of the total likelihood (the weighted sum of the likelihoods of all possible state sequences) instead of the approximation with the Viterbi likelihood (the like-lihood of the best state sequence) normally used in speech recognition. Next to its use in a recognizer, the use of total likelihoods in the context of an automatic word aligrunent task is also addressed shortly. We describe how the search algorithm must be modified and how word lattices based on total likelihoods can be constructed. The total likelihood framework also requires us to make a distinction between upgrading the language model scores or downgrading the acoustic model scores in the recognizer. To help in deciding between these two alternatives, some theoretical foundation is given to the practice of making a weighted combination of language and acoustic scores. Finally, the total likelihood and the Viterbi framework are compared in terms of accuracy and computational effort on the Wall Street Journal recognition task, while the accuracy of word alignments is evaluated on a large Dutch corpus.
Woolcano: An Architecture And Tool Flow For Dynamic Instruction Set Extension On Xilinx Virtex-4 FX

In this paper, we introduce the Woolcano reconfigurable processor architecture. The architecture is based on the Xilinx Virtex-4 FX FPGA and leverages the Auxiliary Processing Unit (APU) as well as the partial reconfiguration capabilities to provide dynamically reconfigurable custom instructions. We also present a hardware tool flow that automatically translates software functions into custom instructions and a software tool flow that creates binaries using these instructions. While previous research on processors with reconfigurable functional units has been performed predominantly with simulation, the Woolcano architecture allows for exploring dynamic instruction set extension with commercially available hardware. Finally, we present a case study demonstrating a custom floating-point instruction generated with our approach, which achieves a 40x speedup over software-emulated floating-point operations and a 21% speedup over the Xilinx hardware floating-point unit.
Elephant: Sequence Labeling for Word and Sentence Segmentation

Tokenization is widely regarded as a solved problem due to the high accuracy that rulebased tokenizers achieve. But rule-based tokenizers are hard to maintain and their rules language specific. We show that highaccuracy word and sentence segmentation can be achieved by using supervised sequence labeling on the character level combined with unsupervised feature learning. We evaluated our method on three languages and obtained error rates of 0.27 ‰ (English), 0.35 ‰ (Dutch) and 0.76 ‰ (Italian) for our best models.
Hand-Eye Calibration Using Dual Quaternions

To relate measurements made by a sensor mounted on a mechanical link to the robot’s coordinate frame, we must first estimate the transformation between these two frames. Many algorithms have been proposed for this so-called hand-eye calibration, but they do not treat the relative position and orientation in a unified way. In this paper, we introduce the use of dual quaternions, which are the algebraic counterpart of screws. Then we show how a line transformation can be written with the dual-quaternion product. We algebraically prove that if we consider the camera and motor transformations as screws, then only the line coefficients of the screw axes are relevant regarding the hand-eye calibration. The dual-quaternion parameterization facilitates a new simultaneous solution for the hand-eye rotation and translation using the singular value decomposition. Real-world performance is assessed directly in the application of hand-eye information for stereo reconstruction, as well as in the positioning of cameras. Both real and synthetic experiments show the superiority of the approach over two other proposed methods.
Statistical modeling of landslide hazard using GIS

A model for spatial prediction of landslide hazard was applied to a watershed affected by landslide events that occurred during the winter of 1995-96, following heavy rains, and snowmelt. Digital elevation data with 22.86 m x 22.86 m resolution was used for deriving topographic attributes used for modeling. The model is based on the combination of logistic regression and principal component analysis (PCA) of road related landslides and assumes that the meteorologic factors which caused failures in the past will cause failures in the future. This model was intended to provide forest land managers with additional information on landslide hazards associated with roads. The advantage of the model is that it allows rapid assessment of spatial correlation of the topographic attributes on large areas. A Geographic Information Systems derived map using the principal component analysis model delineates areas with relatively high probabilities of failure in the basin.
Providing Multi Source Tag Recommendations in a Social Resource Sharing Platform

In today's information environments, tagging is widely used to provide in- formation about arbitrary types of digital resources. This information is usually created by end users with different motivations and for different kinds of purposes. When aim- ing to support users in the tagging process, these differences play an important role. In this paper several approaches to generate tag recommendations are discussed, and a prototypical recommender system for the social resource sharing platform ALOE is presented. This interactive system allows users to control the generation of the recom- mendations by selecting the sources to be used as well as their impact. The component was introduced at DFKI, and a first evaluation showed that the recommender compo- nent was considered as helpful by a majority of users.
Psychometric properties of the Adolescent Sleep Hygiene Scale

This study evaluated the psychometric properties of the Adolescent Sleep Hygiene Scale (ASHS), a self‐report measure assessing sleep practices theoretically important for optimal sleep. Data were collected on a community sample of 514 adolescents (16–19; 17.7 ± 0.4 years; 50% female) participating in the late adolescent examination of a longitudinal study on sleep and health. Sleep hygiene and daytime sleepiness were obtained from adolescent reports, behavior from caretaker reports, and sleep‐wake estimation on weekdays from wrist actigraphy. Confirmatory factor analysis indicated the empirical and conceptually based factor structure were similar for six of the eight proposed sleep hygiene domains. Internal consistency of the revised scale (ASHSr) was α = 0.84; subscale alphas were: physiological: α = 0.60; behavioural arousal: α = 0.62; cognitive/emotional: α = 0.81; sleep environment: α = 0.61; sleep stability: α = 0.68; daytime sleep: α = 0.78. Sleep hygiene scores were associated positively with sleep duration (r = 0.16) and sleep efficiency (r = 0.12) and negatively with daytime sleepiness (r = −0.26). Results of extreme‐groups analyses comparing ASHSr scores in the lowest and highest quintile provided further evidence for concurrent validity. Correlations between sleep hygiene scores and caretaker reports of school competence, internalizing and externalizing behaviours provided support for convergent validity. These findings indicate that the ASHSr has satisfactory psychometric properties for a research instrument and is a useful research tool for assessing sleep hygiene in adolescents.
The Icosian Code and the $E_8$  Lattice: A New  $4\,\times\,4$ Space–Time Code With Nonvanishing Determinant

This paper introduces a new rate-2, full-diversity space-time code for four transmit antennas and one receive antenna. The 4times4 codeword matrix consists of four 2times2 Alamouti blocks with entries from Q(i,radic5) , and these blocks can be viewed as quaternions which in turn represent rotations in R 3 . The Alamouti blocks that appear in a codeword are drawn from the icosian ring consisting of all linear combinations of 120 basic rotations corresponding to symmetries of the icosahedron. This algebraic structure is different from the Golden code, but the complex entries are taken from a common underlying field. The minimum determinant is bounded below by a constant that is independent of the signal constellation, and the new code admits a simple decoding scheme that makes use of a geometric correspondence between the icosian ring and the E 8 lattice.
Exploring the transcriptome space of a recombinant BHK cell line through next generation sequencing

Baby Hamster Kidney (BHK) cell lines are used in the production of veterinary vaccines and recombinant proteins. To facilitate transcriptome analysis of BHK cell lines, we embarked on an effort to sequence, assemble, and annotate transcript sequences from a recombinant BHK cell line and Syrian hamster liver and brain. RNA‐seq data were supplemented with 6,170 Sanger ESTs from parental and recombinant BHK lines to generate 221,583 contigs. Annotation by homology to other species, primarily mouse, yielded more than 15,000 unique Ensembl mouse gene IDs with high coverage of KEGG canonical pathways. High coverage of enzymes and isoforms was seen for cell metabolism and N‐glycosylation pathways, areas of highest interest for biopharmaceutical production. With the high sequencing depth in RNA‐seq data, we set out to identify single‐nucleotide variants in the transcripts. A majority of the high‐confidence variants detected in both hamster tissue libraries occurred at a frequency of 50%, indicating their origin as heterozygous germline variants. In contrast, the cell line libraries' variants showed a wide range of occurrence frequency, indicating the presence of a heterogeneous population in cultured cells. The extremely high coverage of transcripts of highly abundant genes in RNA‐seq enabled us to identify low‐frequency variants. Experimental verification through Sanger sequencing confirmed the presence of two variants in the cDNA of a highly expressed gene in the BHK cell line. Furthermore, we detected seven potential missense mutations in the genes of the growth signaling pathways that may have arisen during the cell line derivation process. The development and characterization of a BHK reference transcriptome will facilitate future efforts to understand, monitor, and manipulate BHK cells. Our study on sequencing variants is crucial for improved understanding of the errors inherent in high‐throughput sequencing and to increase the accuracy of variant calling in BHK or other systems.

rat head holder for simultaneous scanning of two rats in small animal PET canners : Design , construction , feasibility testing and kinetic validation

To reduce imaging costs, we designed a head holder for scanning two rats simultaneously in small animal PET scanners. Our goals were (i) to maintain high sensitivity and (ii) to minimize repositioning error between scans. Methods: A semi-stereotaxic dual rat head holder was designed and constructed for dual rat scanning in our IndyPET-II scanner and the commercial microPET P4. It was also used for single rat scanning in a small-bore, high-resolution animal scanner (“ISAP”). Positional repeatability was validated via multiple [11C]Raclopride scans of a single rat on different days. Accuracy of repositioning was determined by visual comparison of images, and by metrics derived through image alignment. Kinetic validation was assessed via analysis of [18F]Fluorodeoxyglucose ([18F]FDG) dynamic PET studies of six rats. Each rat was scanned twice: once individually, with brain positioned at the center of field of view (CFOV), and once with a partner, with brain away from CFOV. Both rats were injected with FDG during C T catter correction each dual rat session. Patlak uptake constants (Ki) were calculated from whole brain images. Effects of attenuation and scatter correction on single versus dual scan images were explored. Results: Image comparison and alignment metrics indicated excellent repositioning of rats. Scaled timeactivity-curves from single and dual rat scans were indistinguishable. Average single and dual scan Ki values differed by only 6.3 ± 7.5%. ing in mise E Conclusion: Dual rat scann ning and does not compro
