Dominance-solvable lattice games

This paper derives sufficient and necessary conditions for dominance-solvability of so-called lattice games whose strategy sets have a lattice structure while they simultaneously belong to some metric space. The argument combines and extends Moulin's (1984) approach for nice games and Milgrom and Roberts' (1990) approach for supermodular games. The analysis covers - but is not restricted to - the case of actions being strategic complements as well as the case of actions being strategic substitutes. Applications are given for n-firm Cournot oligopolies, auctions with bidders who are optimistic - respectively pessimistic - with respect to an imperfectly known allocation rule, and Two-player Bayesian models of bank runs.
Parallel Molecular Dynamics : Communication Requirements forMassively Parallel

Molecular mechanics and dynamics are becoming widely used to perform simulations of molecular systems , from large-scale computations of materials to the design and modeling of drug compounds. In this paper we address two major issues: a good decomposition method that can take advantage of future massively parallel processing systems for modest-sized problems in the range of 50,000 atoms and the communication requirements needed to achieve 30 to 40% eeciency on MPPs. We analyzed a scalable benchmark molecular dynamics program executing on the Intel Touch-stone Delta parallelized with an interaction decomposition method. Using a validated analytical performance model of the code, we determined that for an MPP with a four-dimensional mesh topology and 400 MHz processors the communication startup time must be at most 30 clock cycles and the network bandwidth must be at least 2.3 GB/s. This connguration results in 30 to 40% eeciency of the MPP for a problem with 50,000 atoms executing on 50,000 processors.
Evaluation Method of Node Centrality in Complex Directed Network

According to the research on node centrality of complex network, the existing methods although take the global and local importance of node into account, but don't consider the importance of adjacent edges and the direction of interaction. For this, provides a new method for measuring the node centrality of complex directed network, considers the node's role in network efficiency and degree distribution and the importance of adjacent edges to make the evaluation of node centrality more precisely. An illustrative example proves that the method is reasonable and valid.
Performance of IEEE 802.16e OFDMA in Tight Reuse Scenarios

Mobile networks based on the IEEE 802.16e standard are promising candidates for providing broadband wireless access to mobile users. Due to the flexibility of the physical layer definition based on Orthogonal Frequency Division Multiple Access (OFDMA), it is possible to adjust the networks according to IEEE 802.16e to meet different requirements, e.g., system bandwidth. However, these networks cannot guarantee a reliable transmission in scenarios with frequency reuse of 1 to users at the cell border which achieve only poor Signal to Interference plus Noise Ratio (SINR) conditions due to the high amount of interference from neighbouring cells. Link level simulations provided in this paper show that transmission with a sufficiently low block error probability is achieved for SINR conditions above 4 dB. To improve the SINR conditions at the cell border, a system design is proposed that coordinates the resource allocation among the cells. The available subcarriers shall not be used in an omnidirectional way within the cell, but instead shared among the sectors of a cell that neighbouring sectors do not utilise the same subcarriers and interference can be reduced. System level simulations show that the sector and user throughput can be double with the proposed system design compared to an omnidirectional transmission, although the average amount of allocated radio resource units to each user is equal in both scenarios.
Query-Focused Multi-Document Summarization Using Co-Training Based Semi-Supervised Learning

This paper presents a novel approach to query-focused multi-document summarization. As a good biased summary is expected to keep a balance among query relevance, content salience and information diversity, the approach first makes use of both the content feature and the relationship feature to select a number of sentences via the co- training based semi-supervised learning, which can identify the query relevant sentences beyond a single point of view. Then the ranking algorithm based on Markov chain random walks is employed on the relevant sentences by encouraging content salience and information diversity in a unified framework. The final summary focusing on the integration of relevance, salience and diversity is created after several sentences with the highest overall ranking scores are extracted. We performed experiments on DUC2007 dataset and the evaluation results show that the proposed approach can achieve significant improvement over standard baseline approaches and gain comparable performance to the state-of-the-art systems.
USP51 deubiquitylates H2AK13,15ub and regulates DNA damage response

Wang et al. show that USP51, a previously uncharacterized DUB, deubiquitylates H2AK13,15ub and regulates DNA damage response. In cells, USP51 is recruited to chromatin after DNA damage and regulates the dynamic assembly/disassembly of 53BP1 and BRCA1 foci.
Minor HIV-1 Variants with the K103N Resistance Mutation during Intermittent Efavirenz-Containing Antiretroviral Therapy and Virological Failure

The impact of minor drug-resistant variants of the type 1 immunodeficiency virus (HIV-1) on the failure of antiretroviral therapy remains unclear. We have evaluated the importance of detecting minor populations of viruses resistant to non-nucleoside reverse-transcriptase inhibitors (NNRTI) during intermittent antiretroviral therapy, a high-risk context for the emergence of drug-resistant HIV-1. We carried out a longitudinal study on plasma samples taken from 21 patients given efavirenz and enrolled in the intermittent arm of the ANRS 106 trial. Allele-specific real-time PCR was used to detect and quantify minor K103N mutants during off-therapy periods. The concordance with ultra-deep pyrosequencing was assessed for 11 patients. The pharmacokinetics of efavirenz was assayed to determine whether its variability could influence the emergence of K103N mutants. Allele-specific real-time PCR detected K103N mutants in 15 of the 19 analyzable patients at the end of an off-therapy period while direct sequencing detected mutants in only 6 patients. The frequency of K103N mutants was <0.1% in 7 patients by allele-specific real-time PCR without further selection, and >0.1% in 8. It was 0.1%–10% in 6 of these 8 patients. The mutated virus populations of 4 of these 6 patients underwent further selection and treatment failed for 2 of them. The K103N mutant frequency was >10% in the remaining 2, treatment failed for one. The copy numbers of K103N variants quantified by allele-specific real-time PCR and ultra-deep pyrosequencing agreed closely (ρ = 0.89 P<0.0001). The half-life of efavirenz was higher (50.5 hours) in the 8 patients in whom K103N emerged (>0.1%) than in the 11 patients in whom it did not (32 hours) (P = 0.04). Thus ultrasensitive methods could prove more useful than direct sequencing for predicting treatment failure in some patients. However the presence of minor NNRTI-resistant viruses need not always result in virological escape. Trial registration ClinicalTrials.gov NCT00122551
Trellis-Based Baud-rate Timing Recovery Loop for Magnetic Recording Channels

Timing recovery is crucial for magnetic recording systems. A conventional timing recovery loop (also known as the phase-locked loop) consists of a timing error detector (TED), a loop filter, and a voltage controlled oscillator (VCO), all of which process the samples in a sequential manner. This sequence of operations in the timing recovery loop performs well if the timing error is a small fraction of the bit interval. However, in the cycle-slip regions, the timing error is comparable to the bit interval, and the loop fails. In this paper, we represent the timing error in magnetic recording systems using a discrete Markov model that does not confine the timing error to only small fractions of the bit interval. By utilizing such a model, we derive an optimal baud-rate processing unit that does not perform tasks in sequence, but jointly. The derived unit has a similar structure as the classical first-order phase-locked loop (PLL). Simulation results show that the new detector outperforms the standard Mueller and Muller phase-locked loop. This performance gain is substantial if the timing error process is extremely noisy or if there is residual frequency-offset. For moderately low-noise timing errors without residual frequency-offset, the improvement over the Mueller and Müller phase-locked loop is just marginal.
A Bayesian Method for Learning POMDP Observation Parameters for Robot Interaction Management Systems

Technology has allowed robots to enter more personal settings in our society, appearing in environments alongside humans. These new situations provide a new set of problems, including the interaction and control of the robot by untrai ned humans, as well as adapting to an unconstrained world designed for humans. In this paper, we address the issue of robot learning in these environments while taking advantage of a user working alongside the robot. We present a framework for gradually learning a model of the user through a parametric observation function. This type of framework allows us to begin with a rough model of the world and adjust it from experience. By relying on an oracle providing optimal policy information, we are able to learn the observation model and adjust the robot’s behavior to match that of the oracle. We address the problems of learning and modifications necessary to handle the observation function and learning for rare events. We demonstrate the feasibilty of the algorithm on a robot-interaction domain and compare against a model-free method for action-selection.
Developing a Gendered Participatory Prevention Counselling Approach for Gender Based Violence among Soldiers Families in Eastern, Zambia

Much has been documented worldwide, on Gender Based Violence due to its existence and this has been alluded due to lack of a proper defined counseling strategies especially among Sub-Saharan African Countries. This has led to fatal injuries and emotional stress which many times has resulted into deaths for both men and women in various communities that also includes military communities WHO (2008). This is a source of concern as Zambia‟s Geo-Position is within the same area. While the majority of the victims are females it must be noted that the males are also not excluded.
Decision-making about the resolution of social dilemmas : outcome heterogeneity , individual differences in social values and the exercise of power

This paper summarizes some social psychological research into the conditions under which solutions to social dilemmas are voluntarily introduced (instrumental cooperation). Consistent with the research of authors such as Knight (1992) and Keohane & Ostrom, (1995), it is assumed that a wide range of inequalities can influence preference for change and that ‘power’ may be exercised over this decision-making process. Several studies have now been conducted and are outlined in this paper. Some directions for future research are suggested and the importance of interdisciplinary work is emphasized.
PUPPIES: Transformation-Supported Personalized Privacy Preserving Partial Image Sharing

Sharing photos through Online Social Networks is an increasingly popular fashion. However, it poses a seriousthreat to end users as private information in the photos maybe inappropriately shared with others without their consent. This paper proposes a design and implementation of a system using a dynamic privacy preserving partial image sharing technique (namely PUPPIES), which allows data owners to stipulate specific private regions (e.g., face, SSN number) in an image and correspondingly set different privacy policies for each user. As a generic technique and system, PUPPIES targets at threats about over-privileged and unauthorized sharing of photos at photo service provider (e.g., Flicker, Facebook, etc) side. To this end, PUPPIES leverages the image perturbation technique to "encrypt" the sensitive areas in the original images, and therefore it can naturally support popular image transformations (such as cropping, rotation) and is well compatible with most image processing libraries. The extensive experiments on 19,000 images demonstrate that PUPPIES is very effective for privacy protection and incurs only a small computational overhead. In addition, PUPPIES offers high flexibility for different privacy settings, and is very robust to different types of privacy attacks.
Development of an Experimental Model of BACnet-based Lighting Control System

Lighting control system provides various benefits in building management such as operational convenience, energy saving and peak demand control. BACnet(building automation and control networks) is an international standard communication protocol for building automation and control networks. In this study, we developed an experimental model of BACnet-based daylighting and fluorescent lighting dimming control system. The experimental model consists of lighting control system and a mockup of indoor fluorescent lighting facility, which are interconnected using BACnet protocol. Using the experimental model, we evaluated the performance of BACnet-based lighting control system. Results from the experimental model show that the energy consumption for lighting can be reduced up to 40%.
The Generation Gap: Relative Earnings of Young and Old Workers in Italy

We describe the evolution of the relative earnings of young male workers and the evolution of the age-earnings profiles across cohorts in the last three decades. We draw on administrative records to document a significant deterioration of entry wages over the 1990s in the presence of basically stable experience profiles. We supplement the analysis with the Bank of Italy's Survey on Household Income and Wealth and show that the wage gap between younger and older workers widened in the 90s for all levels of educational attainment. These developments are not accounted for by changes in relative skill-age labor supplies or in other potential socio-demographic determinants of wages. We argue that they were probably the result of partial labor market reforms that generated a dual labor market along the age dimension, opening a gap between the earnings of old incumbent workers and those of new labor market entrants.
Recognition of randomly presented one-, two-, and three-pair dichotic digits by children and young adults.

PURPOSE To establish normative data for children and to characterize developmental differences in performance with the free recall version of the Randomized Dichotic Digits Test. RESEARCH DESIGN Group comparison of behavioral data derived from administration of the Randomized Dichotic Digits Test. STUDY SAMPLE Children from 10 to 18 years of age (167) and young adults from 19 to 28 years of age (50). RESULTS Performance improved with age across all types of digit pairs, especially in the left ear, leading to smaller interaural asymmetries among older participants. A left-ear advantage was produced by 39 subjects (18%), only two of whom were left-handed. Normative data are reported for right and left ear scores and for interaural asymmetry (percent correct difference between the two ears) under one-, two-, and three-pair conditions of the test and for interaural asymmetry across the entire test. A unilateral deficit was identified in children (15.5%) and young adults (12%) for the left ear and in children (11.3%) and young adults (6%) for the right ear. A bilateral deficit was also identified in children (6.5%) and young adults (6%). CONCLUSIONS This test may be useful as part of the clinical battery for identifying binaural integration weaknesses and referring individuals for auditory rehabilitation for interaural asymmetry (ARIA).
Coordinate Transcriptional Control in the Hyperthermophilic Archaeon Sulfolobus solfataricus

ABSTRACT The existence of a global gene regulatory system in the hyperthermophilic archaeon Sulfolobus solfataricus is described. The system is responsive to carbon source quality and acts at the level of transcription to coordinate synthesis of three physically unlinked glycosyl hydrolases implicated in carbohydrate utilization. The specific activities of three enzymes, an α-glucosidase (malA), a β-glycosidase (lacS), and an α-amylase, were reduced 4-, 20-, and 10-fold, respectively, in response to the addition of supplementary carbon sources to a minimal sucrose medium. Western blot analysis using anti-α-glucosidase and anti-β-glycosidase antibodies indicated that reduced enzyme activities resulted exclusively from decreased enzyme levels. Northern blot analysis of malA and lacSmRNAs revealed that changes in enzyme abundance arose primarily from reductions in transcript concentrations. Culture conditions precipitating rapid changes in lacS gene expression were established to determine the response time of the regulatory system in vivo. Full induction occurred within a single generation whereas full repression occurred more slowly, requiring nearly 38 generations. SincelacS mRNA abundance changed much more rapidly in response to a nutrient down shift than to a nutrient up shift, transcript synthesis rather than degradation likely plays a role in the regulatory response.
Detecting morphed face images

Widespread deployment of Automatic Border Control (ABC) along with the electronic Machine Readable Travel Documents (eMRTD) for person verification has enabled a prominent use case of face biometrics in border control applications. Many countries issue eMRTD passports on the basis of a printed biometric face photo submitted by the applicant. Some countries offer web-portals for passport renewal, where citizens can upload their face photo. These applications allow the possibility of the photo being altered to beautify the appearance of the data subject or being morphed to conceal the applicant identity. Specifically, if an eMRTD passport is issued with a morphed facial image, two or more data subjects, likely the known applicant and one or more unknown companion(s), can use such passport to pass a border control. In this work we propose a novel scheme to detect morphed face images based on facial micro-textures extracted using statistically independent filters that are trained on natural images. Given a face image, the proposed method will obtain a micro-texture variation using Binarized Statistical Image Features (BSIF), and the decision is made using a linear Support Vector Machine (SVM). This is first work carried out towards detecting the morphed face images. Extensive experiments are carried out on a large-scale database of 450 morphed face images created using 110 unique subjects with different ethnicity, age, and gender that indicates the superior performance.
Using the Observer-Based Psychophysical Procedure to Assess Localization Acuity in Toddlers Who Use Bilateral Cochlear Implants

Hypothesis: Localization acuity will emerge in deaf children who receive bilateral cochlear implants (BI-CIs) before the age of 3 years but not in age-matched children who use a single device. Background: There is a growing clinical trend in which infants with severe-to-profound sensorineural hearing loss are receiving BI-CIs by 3 years. Although there is general agreement that better communicative and educational outcomes are achieved when the first implant is provided at a young age, there are few behavioral data showing the functional benefits of providing infants with BI-CIs. One potential benefit of BI-CIs is improved localization acuity, which develops within the first few years of life. Methods: Two groups of children with chronological ages ranging from 26 to 36 months participated: 1) children with normal hearing (n = 8) and 2) children with severe-to-profound sensorineural hearing loss (n = 18). Of the children who are deaf, 10 used BI-CIs, and 8 used unilateral cochlear implants. Localization acuity was measured with a single interval 2-alternative-forced choice right/left discrimination task, and minimum audible angles were computed at a performance level of 80% correct. Behavioral data were collected using the observer-based psychophysical procedure. Results: Preliminary results show that the observer-based psychophysical procedure is a feasible method to measure localization acuity in children with normal hearing and in deaf children with cochlear implants and that localization acuity is emerging in toddlers with BI-CIs but not yet in toddlers with unilateral cochlear implants. Conclusion: These data are among the first to show localization acuity in young children who use BI-CIs.
DACE: Differential Allelic Co-Expression test for estimating regulatory associations of SNP and biological pathway

To identify genomic regions associated with individual gene's expressions, genetical genomic approaches have been developed. The approach treats each gene expression value as a trait to determine the genetic factor that explains the variance of the mRNA expression. However, genes often demonstrate coordinated activities and the patterns and levels of coordination are also regulated. In this research, we present a method, the Differential Allelic Co-Expression (DACE) test that identifies the regulatory association derived by alteration of co-expression patterns within a molecular pathway according to allelic difference of a certain SNP.
Anatomical characterization of Cre driver mice for neural circuit mapping and manipulation

Significant advances in circuit-level analyses of the brain require tools that allow for labeling, modulation of gene expression, and monitoring and manipulation of cellular activity in specific cell types and/or anatomical regions. Large-scale projects and individual laboratories have produced hundreds of gene-specific promoter-driven Cre mouse lines invaluable for enabling genetic access to subpopulations of cells in the brain. However, the potential utility of each line may not be fully realized without systematic whole brain characterization of transgene expression patterns. We established a high-throughput in situ hybridization (ISH), imaging and data processing pipeline to describe whole brain gene expression patterns in Cre driver mice. Currently, anatomical data from over 100 Cre driver lines are publicly available via the Allen Institute's Transgenic Characterization database, which can be used to assist researchers in choosing the appropriate Cre drivers for functional, molecular, or connectional studies of different regions and/or cell types in the brain.
Small Discoveries can have Great Consequences in Love Affairs: the Case of Beauty and the Beast

A mathematical model is proposed for interpreting the love story portrayed by Walt Disney in the film "Beauty and The Beast". The analysis shows that the story is characterized by a sudden explosion of sentimental involvements, revealed by the existence of a saddle-node bifurcation in the model. The paper is interesting not only because it deals for the first time with catastrophic bifurcations in specific romantic relationships, but also because it enriches the list of examples in which love stories are satisfactorily described through Ordinary Differential Equations.
