Graph based Remote Radio Unit selection in coordinated multipoint systems

In this paper, a Remote Radio Unit (RRU) selection scheme is proposed in coordinated multipoint transmission (CoMP) systems to improve the system throughput, especially for cell-edge performance. An assist graph is constructed according to the channel condition between the RRU and User equipment. Based on the assist graph, a heuristic algorithm is proposed to optimize the system performance with fairness constraints. The simulation results show that the proposed scheme can improve the performance of system throughput.
A LPV EMS regulator for the parallel HEV with battery life prolongation

This paper is concerned with the design of a discrete-time linear parameter varying (LPV) regulator for a parallel hybrid electric vehicle (PHEV) based on an already exist optimal energy management strategy (EMS). The aim is to determine the regulating quantity of battery current and the power split ratio between engine and battery with respect to the achieved optimal ones by the exist optimal EMS, according to the driving cycle variation and battery capacity degradation. The system is modelled under linear fractional transformation (LFT) form with varying velocity and battery capacity represented as an uncertainty blocks. The discrete-time linear parameter varying (LPV) regulator which is scheduled by the varying parameters is synthesized using the approach proposed in [1]. The battery state of charge (SOC) estimation method based on the Kalman Filter and the battery capacity estimation method based on the Least Mean Square (LMS) are also given.
A New Multi-objective Differential Evolution Algorithm

A new multi-objective differential evolution algorithm is proposed. A dual elitist selection strategy based on Individual Pareto Rank and Individual Density is employed in the proposed new algorithm. It also remains the characteristic of keeping elitists. The corresponding effects comparisons of new algorithm with other classic multi-objective evolutionary algorithms show that new algorithm require initial population small in size, fewer iterations, and output more optimal solutions. It can improve the diversity metric significantly while ensuring satisfactory convergence metric.
Concealment of Sexual Minority Identities in Interviewer-Administered Government Surveys and Its Impact on Estimates of Suicide Ideation Among Bisexual and Gay Men

ABSTRACT Bisexual and gay men are at increased risk of suicide ideation. Characterizing this risk requires self-disclosure of sexual identities; however, many will conceal their identity when interviewed. The authors investigated the impact of the resulting information bias within the Canadian Community Health Survey (CCHS). Expected probabilities of disclosure were derived from a community-based survey of bisexual and gay men, stratified by sexual identity and other social characteristics. Forty percent of bisexual men and 86% of gay men were willing to disclose to CCHS interviewers. The odds of suicide ideation were higher for bisexual (odds ratio [OR] = 4.91) and gay (OR = 3.63) men compared to heterosexual men. After bias analysis these disparities remained significant but were attenuated, with greater attenuation for bisexual (adjusted OR = 3.53) than for gay (adjusted OR = 3.52) men. The authors recommend that researchers continue exploring bias in estimated sexual minority health disparities, and that population surveys be more inclusive of bisexual-identified individuals.
Special Issue on Networked Control Systems

M OTIVATED by the accelerating technological convergence of communications, control, and computing, researchers from a variety of disciplines have become interested in the exciting potential and technological challenges of networked control systems (NCSs). In the broadest terms, these systems are comprised of actuators, sensors, and controllers whose operation is coordinated through some form of communication network. The system elements are typically spatially isolated from one another, operating in an asynchronous manner and communicating over a wide area via both wired and wireless links. While work to build the foundations of networked control systems technology has accelerated in both industrial and university research centers, many fundamental questions regarding stable operation of interconnected hard real-time systems, signal coding and control information flow, peer-to-peer networking, effects of the network on the performance of control systems, etc. remain to be answered. Nevertheless, there has been a proliferation of industrial control system networking technologies, with names like Profibus, Interbus, ControlNet, and SERCOS (to name only a few). With the caveat that these technologies are evolving extremely rapidly, the reader is referred to [1] for a recent description of industrial control networks. Industrial control is only one application domain where net-worked real-time systems are becoming increasingly important. Sensor webs, ad hoc networks of autonomous mobile agents (such as UAVs), and arrays of micro-devices (such as micro-valve arrays, optical switches, RF switches, MEMS-based spatial light modulators, etc.) all present challenges in coordinating communication and control, and it is our hope that the research described in this Special Issue will help readers to see that there is an emerging theoretical foundation for treating a variety of applied problems. One common problem to be addressed when considering net-worked control systems is whether there is sufficient communication bandwidth to feed back information to the controller and then send the control commands to the actuators and the plant. In traditional models of control systems, information from the sensors is assumed to be instantaneously available, as in the case of continuous-time systems, and at the sampling time, in the case of discrete-time systems. There may also be delays in transferring this information to the controller and transmitted signals may be corrupted by noise, but when the information arrives it is assumed to be essentially complete (although possibly corrupted by noise). This is in contrast to the NCSs, where limited channel capacity may severely constrain the bit rate in the feedback signal so …
Phases and the syntax of applicatives

Until recently, cross-linguistic differences in the syntax of applicative constructions have been attributed to arbitrary variation (e.g. Baker 1988, Bresnan & Moshi 1990, Marantz 1993, Ura 1996). For example, it has been argued (McGinnis 1998a, 1998b) that Amovement, like A-bar movement, respects relativized minimality, and that crosslinguistic variations in the formation of the double-object construction arise from the presence or absence of an “escape hatch,” which allows the lower object to leapfrog over the higher one to the subject position. Like other accounts that assume arbitrary variation, this account raises a serious learnability question: how could a child learn whether such an escape hatch is available? The present paper offers the beginnings of an answer to this question. The central proposal is that a substantial amount of the cross-linguistic variation in properties of “applicative” constructions (such as the double-object construction) is reducible to a lexical parameter. The lexicon contains one or more applicative (Appl) heads, which may denote a relation between an event and an individual, or a relation between two individuals (Pylkkänen 2000). (1a) shows the first type, and (1b) shows the second.

Do Auction Bids Betray Expectations-Based Reference Dependent Preferences? A Test, Experimental Evidence, And Estimates Of Loss Aversion

In this paper, we provide a novel experimental auction design that exploits an exogenous variation in the probability of winning to test for the presence of expectations-based reference dependent preferences. We prove that (i) in this design, (which is a one parameter modification of a Becker-de Groote-Marschak (BDM) auction), a lower probability of winning will cause a loss averse agent to bid lower, for a large range of intrinsic values for the object. Data from an experiment demonstrate the existence of this effect. The effect would be absent if preferences were 'standard', or if the status quo was the reference point. Thus we contribute to the nascent literature that empirically documents the importance of expectations as a source of reference points. (ii) We further prove that the experimental design enables unique identification of participants' value distribution and loss averse than men. Finally, as a contribution to experimental methodology, we prove that the BDM mechanism will underestimate loss averse participants' values, we quantify the underestimation, and we suggest methods to bound this bias.
An Automatic Compilation Framework for Configurable Architectures

In this paper we present a framework to implement compilation flows targeting architectures with an heterogeneous structure. We will show techniques for analyzing and transforming the code of the input source program with the aim to identify critical computational kernels. In particular we will describe an high level compilation layer designed to build analytical information completely derived by static analysis and its back-end towards architecture specific layers. Finally we will show a compilation flow targeting an hybrid architecture consisting of a VLIW coupled with a reconfigurable core which exploits the capabilities of our framework.
The Threshold Hypothesis Applied to Three Languages in Contact at School

This study was designed to investigate whether the threshold level hypothesis (Cummins, 1976, 1979) could be applied to a three-language-in-contact school situation. The learning of three languages at school is becoming more and more commonplace throughout the world, some cases in Europe being reviewed. One of these three-language-in-contactschoolsituations is that of the Basque Country, a bilingual Community wherein both Basque and Spanish are official languages, and therefore taught at school. English is taught as a foreign language. The sample was made up of 252 students; 126 of them enrolled in Grade 5 (10-11-year-olds) and who were in their second year of learning English at school, and 126 enrolled in Grade 8 (13-14-year-olds) and who were in their third year of learning English at school. The participants completed Basque, English, and Spanish tests, as well as a background questionnaire and Raven's Progressive Matrices Test. The dependant variable was measured via a test of metalinguistic abilitie.
A New Bumpless Rotor-Flux Position Estimation Scheme for Vector-Controlled Washing Machine

For a washing machine, permanent-magnet (PM) motors are commonly used due to their superior efficiency, high torque-to-volume ratio, and so on. PM motor driving system with vector control scheme requires rotor-flux position information. Hall-effect position sensors are often used for that purpose because their volume is small and is cost effective compared with other types of position sensor such as an encoder, even though they have low resolution of position information. Generally, two low-resolution hall-effect sensors are employed to provide rotor flux position for cost reduction purpose and it means four resolutions per one electrical 360° rotation. The detected rotor-flux position by hall sensor signals is manipulated to change linearly by interpolation method. However, because of electrical and mechanical nonuniformity associated with hall sensors, the calculated or estimated position is not linearly changed. In other words, there exist bumps at the point where hall signal occurs even at the constant speed operation and it degrades control performance. To solve this problem, this paper proposes a novel scheme for bumpless position estimation. In addition, the proposed reduced-order observer does not use mechanical parameters such as inertia. The validity and effectiveness of the proposed algorithm are verified by experiments on a top-load washing machine vector-controlled with two Hall-effect sensors.
Muscleblind-Like 1 Knockout Mice Reveal Novel Splicing Defects in the Myotonic Dystrophy Brain

Myotonic dystrophy type 1 (DM1) is a multi-systemic disorder caused by a CTG trinucleotide repeat expansion (CTGexp) in the DMPK gene. In skeletal muscle, nuclear sequestration of the alternative splicing factor muscleblind-like 1 (MBNL1) explains the majority of the alternative splicing defects observed in the HSA LR transgenic mouse model which expresses a pathogenic range CTGexp. In the present study, we addressed the possibility that MBNL1 sequestration by CUGexp RNA also contributes to splicing defects in the mammalian brain. We examined RNA from the brains of homozygous Mbnl1 ΔE3/ΔE3 knockout mice using splicing-sensitive microarrays. We used RT-PCR to validate a subset of alternative cassette exons identified by microarray analysis with brain tissues from Mbnl1 ΔE3/ΔE3 knockout mice and post-mortem DM1 patients. Surprisingly, splicing-sensitive microarray analysis of Mbnl1 ΔE3/ΔE3 brains yielded only 14 candidates for mis-spliced exons. While we confirmed that several of these splicing events are perturbed in both Mbnl1 knockout and DM1 brains, the extent of splicing mis-regulation in the mouse model was significantly less than observed in DM1. Additionally, several alternative exons, including Grin1 exon 4, App exon 7 and Mapt exons 3 and 9, which have previously been reported to be aberrantly spliced in human DM1 brain, were spliced normally in the Mbnl1 knockout brain. The sequestration of MBNL1 by CUGexp RNA results in some of the aberrant splicing events in the DM1 brain. However, we conclude that other factors, possibly other MBNL proteins, likely contribute to splicing mis-regulation in the DM1 brain.
A multi-objective genetic algorithm approach to the design of cellular manufacturing systems

In this paper, a multi-objective integer programming model is constructed for the design of cellular manufacturing systems with independent cells. A genetic algorithm with multiple fitness functions is proposed to solve the formulated problem. The proposed algorithm finds multiple solutions along the Pareto optimal frontier. There are some features that make the proposed algorithm different from other algorithms used in the design of cellular manufacturing systems. These include: (1) a systematic uniform design-based technique, used to determine the search directions, and (2) searching the solution space in multiple directions instead of single direction. Four problems are selected from the literature to evaluate the performance of the proposed approach. The results validate the effectiveness of the proposed method in designing the manufacturing cells.
Detection of satellite remnants in the Galactic Halo with Gaia — I. The effect of the Galactic background, observational errors and sampling

We address the problem of identifying remnants of satellite galaxies in the halo of our galaxy with Gaia data. The Gaia astrometric mission offers a unique opportunity to search for and study these remnants using full phase-space information for the halo of our Galaxy. However, the remnants have to be extracted from a very large data set (of the order of 109 stars) in the presence of observational errors and against a background population of Galactic stars. We address this issue through numerical simulations with a view towards timely preparations for the scientific exploitation of the Gaia data. We present a Monte Carlo simulation of the Gaia catalogue with a realistic number of entries. We use a model of the galaxy that includes separate light distributions and kinematics for the bulge, disc and stellar halo components. For practical reasons we exclude the region within Galactic coordinates: −90°≤l≤ 90° and −5°≤b≤ 5°, close to the Galactic plane and centre. Nevertheless, our catalogue contains 3.5 × 108 stars. No interstellar absorption has been modelled, as we limit our study to high Galactic latitudes. We perform tree code 106–body simulations of satellite dwarf galaxies in orbit around a rigid mass model of the Galaxy. We follow the simulations for 1010 yr. The resulting shrinking satellite cores and tidal tails are then added to the Monte Carlo simulation of the Gaia catalogue. To assign photometric properties to the particles we use a Hess diagram for the Solar neighbourhood for Galactic particles, while for the dwarf galaxy particles we use isochrones from the Padova group. When combining the Milky Way and dwarf galaxy models we include the complication that the luminosity function of the satellite is probed at various depths as a function of position along the tidal tails. The combined Galaxy and satellites model is converted to a synthetic Gaia catalogue using a detailed model for the expected astrometric and radial velocity errors, depending on magnitude, colour and sky position of the stars. We explore the feasibility of detecting tidal streams in the halo using the energy versus angular momentum plane. We find that a straightforward search in this plane will be very challenging. The combination of the background population and the observational errors will make it difficult to detect tidal streams as discrete structures in the E–Lz plane. In addition the propagation of observational errors leads to apparent caustic structures in the integrals of motion space that may be mistaken for physical entities. Any practical search strategy will have to use a combination of pre-selection of high-quality data and complementary searches using the photometric data that will be provided by Gaia.
Genistein Modulation of Immune-Associated Genes in LNCaP Prostate Cancer Cell Line

Background: Prostate cancer is the most common form of non-dermatologic cancer and the second leading cause of cancer deaths in the United States. Survival rate for the advanced disease still remains low, so current research is aimed at alternative or adjuvant treatments that will target components of the signal pathways in the progression of carcinogenesis with little or no cytotoxicity. In this study we investigated the effect of genistein on expression levels of genes involved in the immune response pathways. The mechanism of genistein-induced cell death was also investigated. The chemosensitivity of the LNCaP prostate cancer cells to genistein was investigated using ATP and MTS assays, and a caspase binding assay was used to determine apoptosis induction. Several molecular targets/genes were determined using cDNA microarray and RT-PCR analysis. Results: The overall data revealed that genistein induces cell death in a time- and dose-dependent manner, and regulates expression levels of several genes involved in carcinogenesis and immunity including MHC genes that are involved in immune recognition of cells and the DefB1 and the HLA membrane receptor genes involved in immunogenicity. Conclusion: The results of the study indicate that genistein inhibits carcinogenesis of LNCaP prostate cancer growth via regulation of the identified specific targets/pathways in immunogenicity/immune response. The results thus provide significant insight into the roles that genistein could play in immune response to prostate cancer proliferation and potential role in immunotherapy and/or adjuvant therapeutic regimen.
Piggyback Cache Validation for Proxy Caches inthe World Wide

This paper attempts to tackle the cache coherency problem for documents without an expiration time. Rather than use a strictly weak or strong cache consistency approach, we piggyback cache state information onto HTTP requests to a server. In the simplest approach, whenever a proxy cache has a reason to communicate with a server it piggybacks on a list of cached documents for which the expiration time is unknown. This mechanism can reduce the number of requests and connections between a proxy cache and a server, while providing close to strongly consistent cache information. Alternatives that we are considering could also be used to provide a more cost eeective server invalidation mechanism.
Network performance under physical constraints

The performance of an interconnection network in a massively parallel architecture is subject to physical constraints whose impact needs to be re-evaluated from time to time. Fat-trees, and low dimensional cubes have raised a great interest in the scientific community in the last few years and are emerging standards in the design of interconnection networks for massively parallel computers. In this paper we compare the communication performance of these two classes of interconnection networks using a detailed simulation model. The comparison is made using a set of synthetic benchmarks, taking into account physical constraints, as pin and bandwidth limitations, and the router complexity. In our experiments we consider two networks with 256 nodes, a 16-ary 2-cube and 4-ary 4-tree.
Étude des mécanismes de localisation auditive et de leur plasticité dans le cortex auditif humain

Spatial hearing is an important but complex capacity of the auditory system. The human auditory system infers the location of a sound source from a variety of acoustic cues, known as auditory localization cues. Because these cues depend to some degree on morphological and environmental factors that cannot be predicted by the genetic makeup, their processing has to fine-tuned during development. Even in adulthood, some plasticity in the processing of localization cues remains. This plasticity has been studied behaviorally, but very little is known about its neural correlates and mechanisms. The present research aimed to investigate this plasticity, as well as the encoding mechanisms of the auditory localization cues, using both behavioral and neuroimaging techniques. In the first two studies, we shifted the perception of horizontal auditory space using digital earplugs. We showed that young adults rapidly adapt to a large perceived shift and that adaptation is accompanied by changes in hemispheric lateralization of auditory cortex activity, as observed with high-resolution functional MRI. We also confirmed the hypothesis of a hemifield code for horizontal sound source location representation in the human auditory cortex. In a third study, we modified the major cue for vertical space perception using silicone earmolds and showed that the adaptation to this modification was not followed by any aftereffect upon earmolds removal, even at the very first sound presentation. This result is consistent with the hypothesis of a “many-to-one mapping” mechanism in which several spectral profiles can become associated with a given spatial direction. In a fourth study, using functional MRI and taking advantage of the adaptation to silicone earmolds, we revealed the encoding of sound source elevation in the human auditory cortex.
