An Ack Based Visible-Light Data Transmission Protocol

We describe a communication protocol that uses visible-light to provide reliable and in order transfer of data between a pair of machines. Visible-light is a wireless transmission medium that also provides natural protection against eavesdropping since visible light rapidly attenuates with distance and angular variations. We experimentally verify these properties. We also design a flow control algorithm, similar to TCP, for dealing with dynamic ambient brightness, which has a strong impact on the performance of the system.
Multi-user detection based on quantum signal processing

Covariance shaping least squares estimator is a new kind of linear estimator based on covariance shaping in quantum signal processing (QSP) framework. In this paper, the covariance shaping least squares (CSLS) estimator is applied to multi-user detection that leads to a new detection algorithm, covariance shaping multi-user detection algorithm. The numerical simulations in synchronous DS-CDMA communications system are performed and compared with other linear detection algorithms under the same condition. The results show that the performance of covariance shaping multi-user detection is better than that of traditional MF and decorrelation detection, and is an approach to the MMSE detection method. Moreover, covariance shaping multi-user detection method depends only on the userspsila signatures and do not require knowledge of the channel parameters.
Microwave communication links for brain interface applications

Recent experiments have demonstrated the ability of neuroscientists to gain direct access to neural signals in real time, and decode the resulting information to control various prosthetic devices. This - along with deep brain stimulation for Parkinson's disease and a variety of other conditions - extrapolates to a premise that widespread "brain interface" medical device technologies are a real (if long term) possibility. This paper will summarize the various approaches that have been introduced specifically to wirelessly communicate with the brain, including microelectronics technology constraints, power limits, data compression and rate issues.
Face recognition using PCA based algorithm and neural network

In this paper we develop a computational model to identify the unknown person's face by comparing characteristics of face to those of known individuals. Principal Component Analysis, based on information theory concepts, seek a computational model that best describe a face. Eigenface approach is the principal component analysis method, in which small set of characteristic pictures are used to describe the variation between face images. Goal is to find out the eigenvectors (eigenfaces) of the covariance matrix of the distribution, spanned by a training set of face images. Later, every face image is represented by a linear combination of these eigenvectors. The eigenface algorithm has been applied to extract the basic face of the human face images stored in database of faces (e.g. ORL face database). Recognition is performed by projecting a new image into the subspace spanned by the eigenfaces and then classifying the face by comparing its position in face space with the positions of known individuals. In this approach we treat the face recognition problem as an intrinsically two-dimensional (2-D) recognition problem rather than requiring recovery of three dimensional geometry, taking advantage of the fact that faces are normally upright and thus may be described by 2-D characteristic views.
The State of LGBQ Affirmative Therapy Clinical Research: A Mixed-Methods Systematic Synthesis

In the 4 decades since the American Psychiatric Association removed homosexuality from the list of mental disorders, there has been a gradual shift from antigay sentiment among the majority of mental health clinicians to a more tolerant and then affirming approach to treatment with lesbian, gay, bisexual, and queer (LGBQ) individuals (Johnson, 2012; O’Shaughnessy & Spokane, 2013). Alongside this evolution in treatment perspective, there has been a growing emphasis on the importance of utilizing evidence-based practices in clinical work (APA Presidential Task Force on Evidence-Based Practice, 2006). Despite these shifts, there is still limited literature regarding what constitutes effective psychotherapy with LGBQ clients. This article presents the results of a mixed-methods systematic synthesis of 49 empirical studies published between 2000 and 2015 on effective therapeutic interventions with LGBQ clients. We synthesize this growing literature base to provide insight into the status of the field and guidance for clinical application and future research directions.
Effect of the exposure to workplace bullying on turnover intention and the mediating role of job satisfaction, work engagement, and burnout

Planteamiento del problema: Uno de los grandes retos para las organizaciones hoy en dia es la retencion de recursos humanos valiosos porque de ello depende que las mismas se mantengan competitivas globalmente y uno de los factores que puede exacerbar la intencion a renunciar es la exposicion al acoso psicologico. Proposito: El proposito de la presente investigacion fue examinar el efecto de la exposicion al acoso psicologico en la intencion a renunciar al empleo y como la satisfaccion laboral, el engagement con el trabajo y el burnout median la relacion entre el acoso psicologico y la intencion a renunciar. Metodo: Se utilizo un diseno transversal-correlacional y se encuesto un total de 1,046 empleados/as. Se utilizo el modelo de ecuaciones estructurales basado en residuales (PLS-SEM) para examinar las hipotesis del estudio. Resultados: Los resultados sugieren que la exposicion al acoso psicologico tiene un efecto directo en la intencion a renunciar. Ademas, se encontro que la satisfaccion laboral, el engagement con el trabajo y el burnout mediaron parcialmente la relacion entre la exposicion al acoso psicologico y la intencion a renunciar al empleo. Discusion: La exposicion al acoso psicologico puede hacer que las victimas consideren renunciar a sus empleos como una forma de afrontamiento. Las renuncias al empleo por parte de los empleados tienen un costo organizacional sumamente alto en cuanto al reclutamiento y adiestramiento del nuevo personal.
A generic semantic-based framework for cross-domain recommendation

In this paper, we present an ongoing research work on the design and development of a generic knowledge-based description framework built upon semantic networks. It aims at integrating and exploiting knowledge on several domains to provide cross-domain item recommendations. More specifically, we propose an approach that automatically extracts information about two different domains, such as architecture and music, which are available in Linked Data repositories. This enables to link concepts in the two domains by means of a weighted directed acyclic graph, and to perform weight spreading on such graph to identify items in the target domain (music artists) that are related to items of the source domain (places of interest).
A VECTOR SPACE MODEL FOR INFORMATION RETRIEVAL: A MATLAB APPROACH

By and large, three classic framework models have been used in the process of retrieving information: Boolean, Vector Space and Probabilistic. Boolean model is a light weight model which matches the query with precise semantics. Because of its boolean nature, results may be tides, missing partial matching, while on the contrary, vector space model, considering term-frequency, inverse document frequency measures, achieves utmost relevancy in retrieving documents in information retrieval. This paper implements and discusses the issues of information retrieval system with vector space model using MATLAB on Cranfield data collection of aerodynamics domain.
On the Euler numbers of certain moduli spaces of curves and points

We determine the topological Euler number of certain moduli space of 1-dimensional closed subschemes in a smooth projective variety which admits a Zariski-locally trivial fibration with 1-dimensional fibers. The main approach is to use virtual Hodge polynomials and torus actions. The results might shed some light on the corresponding Donaldson-Thomas invariants.
A comparative analysis of the binding affinity of HIV-1 reverse transcriptase to DNA vs. RNA substrates

Title of Document: A COMPARATIVE ANALYSIS OF THE BINDING AFFINITY OF HIV-1 REVERSE TRANSCRIPTASE TO DNA vs. RNA SUBSTRATES Jeffrey T. Olimpo, Jr., Master of Science, 2010 Directed By: Dr. Jeffrey J. DeStefano Professor Department of Cell Biology & Molecular Genetics Human immunodeficiency virus reverse transcriptase (HIV-RT) binds more stably in binary complexes with RNA–DNA versus DNA–DNA. Current results indicate that only the -2 and -4 RNA nucleotides (-1 hybridized to the 3 recessed DNA base) are required for stable binding to RNA–DNA, and even a single RNA nucleotide conferred significantly greater stability than DNA–DNA. Replacing 2 hydroxyls on pivotal RNA bases with 2 -O-methyls did not affect stability, indicating that interactions between hydroxyls and RT amino acids do not stabilize binding. Avian myeloblastosis and Moloney murine leukemia virus RTs also bound more stably to RNA–DNA, but the difference was less pronounced than with HIV-RT. We propose that the Hversus B-form structures of RNA–DNA and DNA–DNA, respectively, allow the former to conform more easily to HIV-RT’s binding cleft, leading to more stable binding. Biologically, this may aid in degradation of RNA fragments that remain after DNA synthesis.
Proliferation is a prerequisite for bacterial superantigen-induced T cell apoptosis in vivo

Staphylococcal enterotoxin B (SEB) is a bacterial superantigen that binds to major histocompatibility complex class II molecules and selectively interacts with T cells that bear certain T cell receptor (TCR) V beta domains. Administration of SEB in adult mice results in initial proliferation of V beta 8+ T cells followed by a state of unresponsiveness resulting from a combination of clonal deletion and clonal anergy in the SEB-reactive population. At this time, it is unclear what relationship exists between the T cells that have proliferated and those that have been deleted or have become anergic. Here we show that only a fraction of the potentially reactive V beta 8+ T cells proliferate in response to SEB in vivo, and that all the cells that have proliferated eventually undergo apoptosis. Virtually no apoptosis can be detected in the nonproliferating V beta 8+ T cells. These data demonstrate a causal relationship between proliferation and apoptosis in response to SEB in vivo, and they further indicate that T cells bearing the same TCR V beta segment can respond differently to the same superantigen. The implications of this differential responsiveness in terms of activation and tolerance are discussed.
Structure of Cardiac Muscle Troponin C Unexpectedly Reveals a Closed Regulatory Domain*

The regulation of cardiac muscle contraction must differ from that of skeletal muscles to effect different physiological and contractile properties. Cardiac troponin C (TnC), the key regulator of cardiac muscle contraction, possesses different functional and Ca2+-binding properties compared with skeletal TnC and features a Ca2+-binding site I, which is naturally inactive. The structure of cardiac TnC in the Ca2+-saturated state has been determined by nuclear magnetic resonance spectroscopy. The regulatory domain exists in a “closed” conformation even in the Ca2+-bound (the “on”) state, in contrast to all predicted models and differing significantly from the calcium-induced structure observed in skeletal TnC. This structure in the Ca2+-bound state, and its subsequent interaction with troponin I (TnI), are crucial in determining the specific regulatory mechanism for cardiac muscle contraction. Further, it will allow for an understanding of the action of calcium-sensitizing drugs, which bind to cardiac TnC and are known to enhance the ability of cardiac TnC to activate cardiac muscle contraction.
Statistical analysis of four write stability metrics in fully depleted silicon-on-thin-BOX (SOTB) and bulk SRAM cells at low supply voltage

Statistical distributions of four write stability metrics at low supply voltage (VDD) were measured in 1k fully depleted (FD) silicon-on-thin-BOX (SOTB) and bulk SRAM cells. It is found that butterfly curve shows abnormal “two-mode” distributions, while bit-line and word-line margins maintain good normality even at low VDD, which demonstrates bit-line and word-line margins as preferred write stability metrics.

Reform or reversal: the impact of REDD+ readiness on forest governance in Indonesia

Indonesia has turned its alleged role as global leader of land-based carbon emissions into a role as a global trailblazer exploring modalities for Reducing Emissions from Deforestation and Forest Degradation (REDD+). REDD+ readiness is largely about improving forest governance, but this itself is a multilayered concept. This article analyses how the processes and practices of REDD+ readiness are leading to various forest governance reforms in Indonesia. We analysed six dimensions of REDD+ readiness progress over the past six years and the way these interact with land tenure reform and land-use planning. We found evidence that (1) tenure issues are taken more seriously, as evidenced by the development of social safeguard mechanisms and efforts to accelerate the gazettement of forest boundaries, although a constitutional court recognition in 2013 for customary forest management is, however, yet to be operationalized; (2) spatial planning relates forests more clearly to other parts of the landscape in terms of compliance with Nationally Appropriate Mitigation Actions (NAMAs) commitments; and (3) the forest and peatland conversion moratorium initiative led to a revamping of forest management. Despite progress, there are still major obstacles to full REDD+ implementation in Indonesia. The discussion focuses on the weaker part of readiness and possible ways forward.
Clustering sequential data with OPTICS

The Web has enormous, various and knowledgeable data for data mining research. The web is a biggest knowledgeable database with various types of data to mine. One of interesting type of data is user behaviour that mine from server log files. Many algorithms are for clustering and then discover the knowledge from database. In this paper we use OPTICS ("Ordering Points To Identify the Clustering Structure") algorithm to find density based clusters on a social music website data (Last.fm website is a free social platform that share listed music with so different music genres). After pre-processing on music dataset and removing unprofitable data from the dataset was ready to clustering. The clusters are generated by OPTICS algorithm and the average of inter cluster and intra cluster are calculated. Then results are visualized and Euclidean distance measure is used to compare results of intra cluster and inter cluster analyses. Finally showed behavior of clusters that made by OPTICS algorithm on a sequential data.
Substance Use in Adolescents Presenting to the Emergency Department

Adolescent substance use is a dynamic public health problem. Adolescence is a unique developmental period involving overlapping biological, psychological, and social factors which increase the rates of initiation of substance use. The developing adolescent brain is particularly susceptible to the effects of substances and most adults with substance use disorders began to have symptoms and problems in their adolescent years. Yet, for various reasons, most adolescents who use, misuse, abuse, or are addicted to substances do not perceive the need for treatment. Drug and alcohol use among adolescents is a common presentation in hospital Emergency Departments (EDs) and presents in different forms including in association with intoxication, withdrawal states, or trauma associated with drug-related events. For many adolescents with substance use, the Emergency Department (ED) is the first point of contact with medical personnel and thus also serves as a potential entry point into treatment. This article reviews the common ways drug and alcohol problems present in the ED, clinical assessment of the patient and family, screening, laboratory testing, brief interventions in the ED, and referral to treatment beyond the ED. Guidelines on how to manage the shifting terrain of adolescent substance use presenting in EDs across the nation continue to evolve. We highlight that considerable further research is needed to inform effective ED protocols to address this important individual and public health safety concern. Systems of care models which include collaborative teams of diverse stake holders are needed to effectively manage adolescents with substance use disorders.
Conjunctival Transcriptome in Scarring Trachoma

ABSTRACT Trachoma is a poorly understood immunofibrogenic disease process, initiated by Chlamydia trachomatis. Differences in conjunctival gene expression profiles between Ethiopians with trachomatous trichiasis (with [TTI] or without [TT] inflammation) and controls (C) were investigated to identify relevant host responses. Tarsal conjunctival swab samples were collected for RNA isolation and C. trachomatis PCR. Transcriptome-wide microarray experiments were conducted on 42 samples (TTI, n = 13; TT, n = 15; C, n =14). Specific results were confirmed by using multiplex quantitative reverse transcription-PCR for 16 mRNA targets in an independent collection of case-control samples: 386 case-control pairs (TTI, n = 244; TT, n = 142; C, n = 386). The gene expression profiles of cases were consistent with squamous metaplasia (keratins, SPRR), proinflammatory cytokine production (IL1β, CXCL5, and S100A7), and tissue remodeling (MMP7, MMP9, MMP12, and HAS3). There was no difference in the level of IFNγ between cases and controls. However, cases had increased INDO, NOS2A, and IL13RA2 and reduced IL13. C. trachomatis was detected in 1/772. Cases show evidence of ongoing inflammation and tissue remodeling, which were more marked where clinical inflammation was also present. Significantly, these processes appear to be active in the absence of current C. trachomatis infection. There was limited evidence of a TH1 response (INDO and NOS2A) and no association between a TH2 response and cases. The epithelium appears to be actively involved in late cicatricial stages of trachoma through the production of proinflammatory factors (IL1β, CXCL5, and S100A7). Longitudinal studies are needed to investigate which etiological factors and pathways are associated with progressive scarring and whether simply controlling chlamydial infection will halt progression in people with established cicatricial disease.
Dispersion of Carbon Nanotubes: Mixing, Sonication, Stabilization, and Composite Properties

Advances in functionality and reliability of carbon nanotube (CNT) composite materials require careful formulation of processing methods to ultimately realize the desired properties. To date, controlled dispersion of CNTs in a solution or a composite matrix remains a challenge, due to the strong van der Waals binding energies associated with the CNT aggregates. There is also insufficiently defined correlation between the microstructure and the physical properties of the composite. Here, we offer a review of the dispersion processes of pristine (non-covalently functionalized) CNTs in a solvent or a polymer solution. We summarize and adapt relevant theoretical analysis to guide the dispersion design and selection, from the processes of mixing/sonication, to the application of surfactants for stabilization, to the final testing of composite properties. The same approaches are expected to be also applicable to the fabrication of other composite materials involving homogeneously dispersed nanoparticles.

Pitch accents, boundary tones and turn-taking in dutch map task dialogues

The present paper reports on an investigation of Dutch Map Task dialogues, looking for specific melodic turn-keeping cues. The materials were divided into so-called Inter Pausal Units (cf. [1]), and all IPU boundaries were labeled as instances of either turn-keeping or turn-changing. The pitch accents and boundary tones preceding the IPU boundaries were labeled in the ToDI system [2]. Results indicate one particular melodic configuration that seems typically associated with turn-keeping: an accent-lending rise followed by level high pitch (H* %). But also the level boundary tone (%) in itself and – to a lesser extent – the rising pitch accent (H*) seem to function as melodic turn-keeping cues.
Collective migration of an epithelial monolayer in response to a model wound

Using an original microfabrication-based technique, we experimentally study situations in which a virgin surface is presented to a confluent epithelium with no damage made to the cells. Although inspired by wound-healing experiments, the situation is markedly different from classical scratch wounding because it focuses on the influence of the free surface and uncouples it from the other possible contributions such as cell damage and/or permeabilization. Dealing with Madin–Darby canine kidney cells on various surfaces, we found that a sudden release of the available surface is sufficient to trigger collective motility. This migration is independent of the proliferation of the cells that mainly takes place on the fraction of the surface initially covered. We find that this motility is characterized by a duality between collective and individual behaviors. On the one hand, the velocity fields within the monolayer are very long range and involve many cells in a coordinated way. On the other hand, we have identified very active “leader cells” that precede a small cohort and destabilize the border by a fingering instability. The sides of the fingers reveal a pluricellular actin “belt” that may be at the origin of a mechanical signaling between the leader and the followers. Experiments performed with autocrine cells constitutively expressing hepatocyte growth factor (HGF) or in the presence of exogenous HGF show a higher average velocity of the border and no leader.
