Multi-stakeholders' Policy Enforcement for Android

Over the past few decades, the technological advancements in cell phones have brought a dramatic variation in life. Innovative applications and enchanting services provided by smartphones makes it the most ubiquitous consumer electronic device. Therefore smartphone has become paramount source for accessing, storing and sharing of business, personal, social, entertainment and official data. The complexities in handling the data and resource access brings new challenges in preserving user's privacy and access to sensitive resources. Though a lot of work has been done to provide secure access control for desktop and web based collaboration systems, a robust and sophisticated system for mobile device is today's demand. In this work, a security and privacy enhanced mobile framework for a multi-stakeholder environment is proposed. In doing so, the access and usage control requirements from multiple stakeholders have been taken in account. The developed framework is a light weight implementation of access control and privacy protection using secure policy enforcement.
Event-based coding of still images using a bio-inspired frame

The growing interest of event-based systems has influenced image processing field and is expected to be a groundbreaking architecture for image and video compression. The human visual system is an efficient event-based biological system which is a source of inspiration to design an event-based codec. This paper introduces a bio-inspired encoding architecture for still images. A bio-inspired filter is first applied to the input image and then the retinal-filtered image is fed to an Integrate And Fire (IAF) sampler. The spike train produced by the IAF sampler is decoded in order to reconstruct the still image at the receiver. We prove that the retinal filter has a frame structure, so the reconstruction is almost perfect provided that the IAF sampling is sufficiently fine.
Control interference of electrical machines with double-star winding systems driven by independent current controllers

This paper focuses on conditions leading to instability of digitally controlled double three-phase permanent magnet synchronous motors with standard PI controller based voltage source inverters. A first simplified motor model is derived to apprehend the problem. The model is then detailed further to get accurate stability limits. A validation of the analysis is done experimentally on a double star winding permanent magnet synchronous motor. To achieve stability and to fasten the system's dynamic, a new control scheme is proposed, using classical PI controllers with two interconnected inverters.
Simulation of the impact of retroviruses on genome organization of an artificial organism

Retroviruses are RNA viruses whose RNA can be transformed into DNA and inserted in the genome of a host cell. This study prototypes a simulation environment in which a simple artificial organism with a variable-size genome evolves with and without retroviruses. The simulated organisms are called grid walkers. They are evolved to efficiently occupy space on a two-dimensional grid. Grid walkers develop a self-organized genome structure with analogs to biological introns and exons. The introduction of retroviruses is found to cause several significant changes: the rate of genome growth is increased, the number of exons is increased, mean exon size is decreased, and fitness is retarded. The grid walkers are found to evolve heritable fitness in preference to high fitness (“survival of the flattest”), a process that is enhanced when retroviruses are present.
RNA-based mechanisms underlying axon guidance

Axon guidance plays a key role in establishing neuronal circuitry. The motile tips of growing axons, the growth cones, navigate by responding directionally to guidance cues that pattern the embryonic neural pathways via receptor-mediated signaling. Evidence in vitro in the last decade supports the notion that RNA-based mechanisms contribute to cue-directed steering during axon guidance. Different cues trigger translation of distinct subsets of mRNAs and localized translation provides precise spatiotemporal control over the growth cone proteome in response to localized receptor activation. Recent evidence has now demonstrated a role for localized translational control in axon guidance decisions in vivo.
Child Maltreatment and Women’s Adult Sexual Risk Behavior: Childhood Sexual Abuse as a Unique Risk Factor

This study investigated (a) whether childhood sexual abuse (CSA) was uniquely associated with adult sexual risk behavior, after controlling for other types of childhood maltreatment and (b) whether there were additive or interactive effects of different types of maltreatment on adult sexual risk behavior. Participants were 414 women (M age = 28 years) attending a publicly funded STD clinic. All women completed a computerized survey assessing childhood maltreatment (sexual, physical, psychological abuse, and neglect) and sexual risk behavior. Analyses showed that sexual abuse, physical abuse, psychological abuse, and neglect were associated with adult sexual risk behavior. Multivariate analyses that controlled for all other forms of child maltreatment showed that only CSA was uniquely associated with adult sexual risk behavior (i.e., percentage of episodes of unprotected sex in the past 3 months and number of lifetime partners). The authors found little support for an additive or an interactive model of the effects of different types of childhood maltreatment on adult sexual risk behavior; CSA alone was the best predictor of adult sexual risk behavior. Sexual risk reduction interventions are needed for women who were sexually abused as children. Continued research on the effects of multitype maltreatment on adult sexual risk behavior is needed.
STEAM WORKS: Student coders experiment more and experimenters gain higher grades

For the last decade, there has been growing interest in the STEAM approach (essentially combining methods and practices in arts, humanities and social sciences into STEM teaching and research) to develop better research and education, and enable us to produce students who can work most effectively in the current and developing market-place. However, despite this interest, there seems to be little quantitative evidence of the true power of STEAM learning, especially describing how it compares and performs with respect to more established approaches. To address this, we present a comparative, quantitative study of two distinct approaches to teaching programming, one based on STEAM (with an open-ended inquiry-based approach), the other based on a more traditional, non-STEAM approach (where constrained problems are set and solved). Our key results evidence how students exhibit different styles of programming in different types of lessons and, crucially, that students who tend to exhibit more of the style of programming observed in our STEAM lessons also tend to achieve higher grades. We present our claims through a range of visualisations and statistical validations which clearly show the significance of the results, despite the small scale of the study. We believe that this work provides clear evidence for the advantages of STEAM over non-STEAM, and provides a strong theoretical and technological framework for future, larger studies.
The Subprocess Spectrum

Using hierarchical structurings in process design is a frequent process modeling technique. Subprocesses are a common way to enable hierarchical structuring. Current approaches have a tight view on the syntactical restrictions of subprocesses and do not investigate different autonomy properties in detail. This paper fills this gap and broadens the current subprocess definition to a spectrum of possibilities of subprocess notations. Thereby, three classifications are introduced: subprocess autonomy, interaction between parent process and subprocess, and execution of subprocesses.
An effective 3-bit Flash Analog to Digital Converter using 45-nm Technology

In analog and digital converters are tragedies dynamic parts during creation of voltaic structures. This paper, a 0.7-V, 3-bit CMOS flash analog to digital converter is presented at 45-nm technology. The major constituents of ADC are comparators and thermometric code to binary code (TC to BC) encoder. Comparator is the key mechanism mainly used in analog to digital converters (ADCs). For the improved transmission of signals, necessities of best analog to digital converters are requisite. Flash ADCs are valuable module in signal processing and communication system. In digital domain low power and low voltage become a extensive component in that are difficult for designing high speed devices and converters. As require for mixed integrated circuits increase, the design of analog circuits such as operational amplifiers in CMOS technology become more important. The power dissipation for flash ADC is 218.9-μW. This established in the recommended method be able to reduce power consumption equated with the predictable single. In this paper, power consumption of the comparators has reduced, in the mainly vital structure of such ADCs. The power consumption of comparator is 26.72-μW.
Impaired formation of the inner retina in an AChE knockout mouse results in degeneration of all photoreceptors

Blinding diseases can be assigned predominantly to genetic defects of the photoreceptor/pigmented epithelium complex. As an alternative, we show here for an acetylcholinesterase (AChE) knockout mouse that photoreceptor degeneration follows an impaired development of the inner retina. During the first 15 postnatal days of the AChE–/– retina, three major calretinin sublaminae of the inner plexiform layer (IPL) are disturbed. Thereby, processes of amacrine and ganglion cells diffusely criss‐cross throughout the IPL. In contrast, parvalbumin cells present a nonlaminar IPL pattern in the wild‐type, but in the AChE–/– mouse their processes become structured within two ‘novel’ sublaminae. During this early period, photoreceptors become arranged regularly and at a normal rate in the AChE–/– retina. However, during the following 75 days, first their outer segments, and then the entire photoreceptor layer completely degenerate by apoptosis. Eventually, cells of the inner retina also undergo apoptosis. As butyrylcholinesterase (BChE) is present at a normal level in the AChE–/– mouse, the observed effects must be solely due to the missing AChE. These are the first in vivo findings to show a decisive role for AChE in the formation of the inner retinal network, which, when absent, ultimately results in photoreceptor degeneration.
Does Innovation Stimulate Employment? A Firm-Level Analysis Using Comparable Micro-Data from Four European Countries

This paper studies the impact of process and product innovations introduced by firms on employment growth in these firms. A simple model that relates employment growth to process innovations and to the growth of sales separately due to innovative and unchanged products is developed and estimated using comparable firm-level data from France, Germany, Spain and the UK. Results show that displacement effects induced by productivity growth in the production of old products are large, while those associated with process innovations, which are likely to be compensated by price decreases, appear to be small. The effects related to product innovations are, however, strong enough to overcompensate these displacement effects.

Partons and jets in a strongly-coupled plasma from AdS/CFT

We give a pedagogical review of recent progress towards understanding the response of a strongly coupled plasma at finite temperature to a hard probe. The plasma is that of the N=4 supersymmetric Yang-Mills theory and the hard probe is a virtual photon, or, more precisely, an R-current. Via the gauge/gravity duality, the problem of the current interacting with the plasma is mapped onto the gravitational interaction between a Maxwell field and a black hole embedded in the AdS_5 x S^5 geometry. The physical interpretation of the AdS/CFT results can be then reconstructed with the help of the ultraviolet/infrared correspondence. We thus deduce that, for sufficiently high energy, the photon (or any other hard probe: a quark, a gluon, or a meson) disappears into the plasma via a universal mechanism, which is quasi-democratic parton branching: the current develops a parton cascade such that, at any step in the branching process, the energy is almost equally divided among the daughter partons. The branching rate is controlled by the plasma which acts on the colored partons with a constant force ~ T^2. When reinterpreted in the plasma infinite momentum frame, the same AdS/CFT results suggest a parton picture for the plasma structure functions, in which all the partons have fallen at very small values of Bjorken's x. For a time-like current in the vacuum, quasi-democratic branching implies that there should be no jets in electron-positron annihilation at strong coupling, but only a spatially isotropic distribution of hadronic matter.
Rat testin is a newly identified component of the junctional complexes in various tissues whose mRNA is predominantly expressed in the testis and ovary.

Testin I and testin II are the two molecular variants of testin that are synthesized and secreted by Sertoli cells in vitro. N-Terminal and partial internal amino acid sequence analysis of testin I and testin II reveals that these molecules are identical with the exception that testin II has three extra N-terminal amino acids of TAP compared to testin I. Studies using immunohistochemistry suggested that testin is a component of the specialized junctional complexes in the seminiferous epithelium and other tissues. Immunoreactive testin is localized not only at Sertoli-Sertoli and Sertoli-germ cell junctions, but also at sites of similar junctions in the liver, epididymis, kidney, and intestine. Other physiological studies have shown that the secretion of testin is tightly coupled to the presence of germ cells. In view of its possible role in germ cell development and its unique localization in the cell junction, the purpose of the present study was to determine the structure of testin by sequencing its full-length cDNA. Two synthetic degenerate oligonucleotides based on the N-terminal and an internal amino acid sequence were used for polymerase chain reaction (PCR) to obtain a 289-bp cDNA fragment. This PCR product was subsequently used to isolate a 1371-bp cDNA from a cDNA expression library constructed from Sertoli cell poly(A) RNA. This cDNA coded for a 333 amino acid peptide that starts with an ATG initiation codon from the 5' end and ends with a TGA termination codon located 245 nucleotides before the polyadenylation site. The deduced amino acid sequence indicates that testin contains a 16 amino acid signal peptide with two possible cleavage sites that yield 314 and 317 amino acids for testin I and testin II with calculated molecular weights of 36,029 and 36,299, respectively. Comparison of the entire coding region of testin with existing sequences at Genbank, EMBL, and Protein Identification Resource indicates that testin shares 58%, 57.4%, and 61% identity with rat, mouse, and human cathepsin L at the amino acid level, respectively. The positions of all of the 7 Cys residues and 8 of the 10 Trp residues in testin are conserved with respect to those present in cathepsin L. It is noted that Cys-122 in the predicted active site of cathepsin L was replaced with Ser-122 in testin. In view of the striking primary sequence homology between testin and cathepsin L, we assayed the proteolytic activity of testin using conditions known to activate cathepsin L.

A robust and real-time road line extraction algorithm using hough transform in intelligent transportation system application

Since lane information is needed for road security improvement in driver assistance system (DAS), first basic step for this system is extraction of road marking. This paper presents a method to detect and extract of road lines to use in intelligent transportation system (ITS). This method is based on Hough transform concluding of three main phase: preprocessing, segmentation, post processing. The advantage of this method is overcome of existence problems such as noise, clear of road marking. This algorithm is implemented on real road scenes in video sequences taken by stationary traffic cameras. Experimental results demonstrate high accuracy of proposed algorithm as compared with classic method.
A Comparative Study of Issues in Big DataClustering Algorithm with Constraint BasedGenetic Algorithm for Associative Clustering

Clustering can be defined as the process of partitioning a set of patterns into disjoint and homogeneous meaningful groups, called clusters. The growing need for distributed clustering algorithms is attributed to the huge size of databases that is common nowadays. The task of extracting knowledge from large databases, in the form of clustering rules, has attracted considerable attention. Distributed clustering algorithms embrace this trend of merging computations with communication and explore all the facets of the distributed computing environments. Ensemble learning is the process by which multiple models, such as classifiers or experts, are strategically generated and combined to solve a particular computational intelligence problem. An important feature of the proposed technique is that it is able to automatically find the optimal number of clusters (i.e., the number of clusters does not have to be known in advance) even for very high dimensional data sets, where tracking of the number of clusters may be highly impossible. The proposed Optimal Associative Clustering algorithm using genetic algorithm and bayes factor for precision is able to outperform two other state-of-the-art clustering algorithms in a statistically meaningful way over a majority of the benchmark data sets. The result of the proposed optimal associative clustering algorithm is compared with one existing algorithm on two multi dimensional datasets. Experimental result demonstrates that the proposed method is able to achieve a better clustering solution when compared with existing algorithms.
A Flip-Flop Matching Engine to Verify Sequential Optimizations

Equivalence checking tools often use a flip-flop matching step to avoid the state space traversal. Due to sequential optimizations performed during syn- thesis (merge, replication, redundancy removal, . . . ) and don't care conditions, the matching step can be very complex as well as incomplete. If the matching is in- complete, even the use of a fast and efficient SAT solver during the combinational equivalence-checking step may not prevent the failure of this approach. In this pa- per, we present a flip-flop matching engine, which is able to verify optimized circuits and handle don't care conditions.
Full-Featured Pedometer Design Realized with 3-Axis Digital Accelerometer

This article, based on a study of the characteristics of each step a person takes, describes a reference design using the 3-axis ADXL345 accelerometer in a full-featured pedometer that can recognize and count steps, as well as measure distance, speed, and—to an extent—calories burned. The ADXL345’s proprietary (patent pending), on-chip, 32-level first-in, first-out (FIFO) buffer can store data and operate on it for pedometer applications to minimize host processor intervention, thus saving system power—a big concern for portable devices. Its 13-bit resolution (4 mg/LSB) allows pedometers to even measure low-speed walking (where each step represents about 55 mg of acceleration change) with reasonable accuracy. Understanding the Model From the characteristics that can be used to analyze running or walking, we choose acceleration as the relevant parameter. The three components of motion for an individual (and their related axes) are forward (roll), vertical ( yaw), and side (pitch), as shown in Figure 1. The ADXL345 senses acceleration along its three axes: x, y, and z. The pedometer will be in an unknown orientation,
Posttraumatische Belastungsstörung und Depression

Zusammenfassung Traumatische Ereignisse gehen mit einem erhöhten Risiko zur Entwicklung psychischer Erkrankungen einher. Posttraumatische Belastungsstörungen (PTBS) treten häufig mit komorbiden Diagnosen auf, insbesondere depressiven Erkrankungen. In dem Artikel werden die Komorbidität von PTBS und Depression, die Symptomüberlappung sowie therapeutische Möglichkeiten diskutiert. Patienten, die in Folge eines traumatischen Ereignisses eine Depression oder PTBS entwickeln, haben ein erhöhtes Risiko für die jeweils andere Erkrankung. Eine hohe Symptomüberlappung zwischen beiden Störungsbildern ist zu beachten. Verschiedene Faktoren beeinflussen die Effekte eines traumatischen Ereignisses, z. B. die Art der Traumatisierung, das Alter beim Ereignis, Vorerkrankungen oder psychosoziale Stressoren. Psychologische, neuroendokrine und genetische Faktoren werden als Prädiktoren für die Auswirkungen eines traumatischen Ereignisses diskutiert. Bei der psychotherapeutischen und pharmakologischen Behandlung sollte die Komorbidität berücksichtigt werden. Allerdings besteht weiterer Forschungsbedarf, um die therapeutischen Strategien für Patienten mit komorbiden Störungen zu optimieren.
Performance analysis of amplify-and-forward network coding for multicast relay systems

In identical Nakagami-m fading channels, the outage probability performance of network coding for multicast relay system is analyzed. The amplify-and-forward network coding (AFNC) transmission strategy is applied in the system. By using the outage event definition in multiuser communication system and the mutual information expressions of multiple access channels, the approximate expression of outage probability is derived at high SNR and the conclusion that the system diversity gain of AFNC is 2m is also obtained, which is verified by numerical simulations. Simulation results also show that, AFNC can outperform direct transmission without relay in the performances of system outage probability and symbol error ratio.
Managing collaborative expertise: issues and challenges

In this paper we examine the challenges of managing the work of a multi-disciplinary team of experts struggling to develop a computerised mammography system. We argue that work systems intended to develop such innovatory products represent a new form of working both in terms of complexity and in terms of the pace with which they are expected to work. Drawing on the insigts provided by an experienced project manager working with the team, we employ Activity Theory (AT) to identify some key issues – the link between motivation and object formation, supporting boundary crossing and working with contradictions – which seem crucial to fostering the development of such a collaborative work system. However, the necessary project management tools to support such processes are currently lacking.
Stability of Thermoelastic Contact for the Aldo Model

"fA perturbation method is used to investigate the stability of a simple one-dimensional rod model of thermoeiastic contact which exhibits multiple steady-state solutions. A thermal contact resistance is postulated which is a continuous function of the contact pressure or separation. It is found that solutions involving substantial separation and/or contact pressures are always stable, but these are separated by unstable "imperfect contact" solutions in which one of the rods is very lightly loaded or has a very small separation. The results can be expressed in terms of the minimization of a certain energy function. "]
