Proposing a hybrid tag-camera-based identification and navigation aid for the visually impaired

In this paper a barcode-based system to help the visually impaired identity objects in the environment and navigate through unknown territories is introduced. The system is based on the idea of tagging the different objects with 2D barcodes. With the aid of a portable camera and a computing device, the system can recognize and relay the barcode content to the user. We present the advantages of the proposed system compared to those of existing technologies. The different steps for recognizing and extracting the barcodes are described and applied to a sample image.
The Entamoeba histolytica, Arp2/3 Complex Is Recruited to Phagocytic Cups through an Atypical Kinase EhAK1

The parasite Entamoeba histolytica is the etiological agent of amoebiasis and phagocytosis plays a key role in virulence of this organism. Signaling pathways involved in activation of cytoskeletal dynamics required for phagocytosis remain to be elucidated. Phagocytosis is initiated with sequential recruitment of EhC2PK, EhCaBP1, EhCaBP3 and an atypical kinase EhAK1 after particle attachment. Here we show that EhARPC1, an essential subunit of the actin branching complex Arp 2/3 is recruited to the phagocytic initiation sites by EhAK1. Imaging, expression knockdown of different molecules and pull down experiments suggest that EhARPC1 interacts with EhAK1 and that it is required during initiation of phagocytosis and phagosome formation. Moreover, recruitment of EhARPC2 at the phagocytosis initiation by EhAK1 is also observed, indicating that the Arp 2/3 complex is recruited. In conclusion, these results suggests a novel mechanism of recruitment of Arp 2/3 complex during phagocytosis in E. histolytica.
Dealing with temporality when inducing association rules from a retail database

One of the main motivations for employing database mining relates to the decision support problems faced by many retail organizations, particularly when the temporal aspect of the data should be taken into account to support management decisions. The focus of this work was the proposal and development of a computational system able to identify patterns in a database containing sale records from a retail organization and, based on them, infer association rules that also deal with the temporal aspect of the data. Experiments with the system on real data from a retail company, after a two-step pre-processing of the raw data, are presented. The obtained results are analysed and a few conclusions are drawn.
Video Transmission over Mobile Ad-Hoc Network Using WEAC Protocol with VBS Algorithm

Mobile ad hoc networks (MANETs) symbolize difficult distributed systems that contains wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, "ad-hoc" network topologies, allowing people and devices to flawlessly internetwork in areas with no pre-existing communication infrastructure. Video transmission in this area is became popular and useful technique. Basically Routing protocols groups under two categories like Proactive and Reactive. In Proactive or Table-Driven Routing Protocols, each node continuously maintains up-to-date routes to every other node in the network. Routing information is periodically transmitted throughout the network in order to maintain Routing Table consistency. In Reactive Protocols, a node initiates a route discovery throughout the network, only when it wants to send packets to its destination. This paper introduces WEAC-VBS-O Protocol which belongs to Reactive protocol category. In this work WEAC Protocol with VBS Selection algorithm is discussed. It provides better result for video transmission.
REPORTING BIAS AND INFORMATIVENESS IN CAPITAL MARKETS WITH NOISE TRADERS

I discuss a disclosure model in which a manager can bias earnings reports. Informed traders acquire knowledge about the uncertain objectives of the manager and trade based on their superior information with noise traders. In the unique linear equilibrium, the market price corrects the report only for an expected bias. The price efficiency is influenced by the cost of biasing, the number of informed traders and the prior precision of the report. I calculate the liquidity of the market and the utilities of the market participants and I show that the noise traders benefit from more and better informed traders.
Brain Injury in Very Preterm Children and Neurosensory and Cognitive Disabilities during Childhood: The EPIPAGE Cohort Study

Objective To investigate the association of motor and cognitive/learning deficiencies and overall disabilities in very preterm (VPT) children and their relations to gestational age (GA) and brain lesions. Design, Setting, and Participants EPIPAGE is a longitudinal population-based cohort study of children born before 33 weeks’ gestation (WG) in 9 French regions in 1997–1998. Cumulating data from all follow up stages, neurodevelopmental outcomes were available for 90% of the 2480 VPT survivors at 8 years. Main outcomes were association of motor and cognitive deficiencies and existence of at least one deficiency (motor, cognitive, behavioral/psychiatric, epileptic, visual, and/or hearing deficiencies) in three GA groups (24–26, 27–28, and 29–32WG) and four groups of brain lesions (none, minor, moderate, or severe). Results VPT had high rates of motor (14%) and cognitive (31%) deficiencies. Only 6% had an isolated motor deficiency, 23% an isolated cognitive one and 8% both types. This rate reached 20% among extremely preterm. Psychiatric disorders and epilepsy were observed in 6% and 2% of children, respectively. The risks of at least one severe or moderate deficiency were 11 and 29%. These risks increased as GA decreased; only 36% of children born extremely preterm had no reported deficiency. Among children with major white matter injury (WMI), deficiency rates reached 71% at 24–26WG, 88% at 27–28WG, and 80% at 29–32WG; more than 40% had associated motor and cognitive deficiencies. By contrast, isolated cognitive deficiency was the most frequent problem among children without major lesions. Conclusions In VPT, the lower the GA, the higher the neurodisability rate. Cerebral palsy is common. Impaired cognitive development is more frequent. Its occurrence in case without WMI or early motor disorders makes long-term follow up necessary. The strong association between motor impairments, when they exist, and later cognitive dysfunction supports the hypothesis of a common origin of these difficulties.
Numerical study of black-hole formation in Painlevé-Gullstrand coordinates

We study numerically black-hole formation from a collapsing massless scalar field. The use of Painleve-Gullstrand coordinates allows the evolution to proceed until singularity formation. We generate spacetime maps of the collapse, illustrating the evolution of apparent horizons for various initial data. A study of the Choptuik scaling reveals the expected universal values for the critical exponent and echoing period. The periodic oscillations in the supercritical horizon scaling relation, while universal with respect to initial Painleve-Gullstrand data, show unexpected structure with large amplitude cusps.
Low-complexity constrained affine-projection algorithms

This paper proposes low-complexity constrained affine-projection (CAP) algorithms. The algorithms are suitable for linearly constrained filtering problems often encountered in communications systems. The CAP algorithms derived in this paper trade convergence speed and computational complexity in the same way as the conventional affine-projection (AP) algorithm. In addition, data-selective versions of the CAP algorithm are derived based on the concept of set-membership filtering. The set-membership constrained affine-projection (SM-CAP) algorithms include several constraint sets in order to construct a space of feasible solutions for the coefficient updates. The SM-CAP algorithms include a data-dependent step size that provides fast convergence and low mean-squared error. The paper also discusses important aspects of convergence and stability of constrained normalized adaptation algorithms and shows that normalization may introduce bias in the final solution.
Clinicopathological Characteristics of Patients with Gastric Cancer according to the Expression of LIN28A

Background/Aims Although LIN28A is known to potentially play a role in the oncogenesis of various cancers, whether LIN28A expression is a predictor of poor prognosis in patients with gastric cancer has not been fully explored. We sought to evaluate clinicopathological characteristics according to the expression of LIN28A in numerous gastric cancer tissue samples. Methods LIN28A expression was evaluated by immunohistochemical (IHC) analysis of a tissue microarray comprising 288 gastric cancer tissues and 288 adjacent normal tissues. Clinicopathological characteristics, including overall survival, were compared according to LIN28A expression. Results The IHC staining score was lower for the cancer tissues than the normal tissues (p<0.001). However, no significant differences were observed in the clinicopathological characteristics between the low and high LIN28A expression groups. In addition, the 5-year overall survival rate did not differ between the two groups: 75.3% (95% confidence interval [CI], 69.3% to 81.7%) versus 71.6% (95% CI, 63.3% to 80.9%) for low versus high expression, respectively. Conclusions The expression of LIN28A did not appear to play a distinct role in predicting the clinicopathological characteristics of patients with gastric cancer. In addition, LIN28A expression was not an independently associated factor for overall survival in patients with gastric cancer.
A DIGITAL CONTENT MEDIATOR ( DCM ) APPROACH TO IMPLEMENTING LEGITIMATE AND SECURE P 2 P ONLINE TRANSACTIONS

In this paper we extend the Digital Content Mediator (DCM) approach [18], a legitimate online service that uses financial incentives as an effective weapon to fight against online piracy. We provide needed network security support for the DCM service. The DCM mediator is a trusted notary to ensure fair and legitimate deals between digital content selling peers and buying peers. (1) In our design, the mediator sees no raw bits of digital contents. This saves storage and communication resource for the central mediator. (2) For the seller and buyer in a DCMlegitimized transaction, one wants payment and the other wants the content. The DCM protocol ensures that neither of them can stop the protocol in the middle to steal its service without serving the other party. (3) A digital content may have many legitimate copies from large amount of sellers. In a large-scale random network like the Internet, transaction fairness is defined as the condition that a buyer wants to buy the copy from the seller with shortest downloading delay (i.e., largest seller-to-buyer pairwise bandwidth) given the same amount of financial charge. DCM employs flow network security countermeasures to ensure that a seller keeps its bandwidth promises. Our experiments on the Internet confirm the effectiveness of our design.
Recognizing Implicit Discourse Relations through Abductive Reasoning with Large-scale Lexical Knowledge

Discourse relation recognition is the task of identifying the semantic relationships between textual units. Conventional approaches to discourse relation recognition exploit surface information and syntactic information as machine learning features. However, the performance of these models is severely limited for implicit discourse relation recognition. In this paper, we propose an abductive theorem proving (ATP) approach for implicit discourse relation recognition. The contribution of this paper is that we give a detailed discussion of an ATP-based discourse relation recognition model with open-domain web texts.
Bisimilarity Control under Partial Observation of Deterministic Discrete Event Systems

The complexity of the general bisimilarity control problem under partial observation is doubly exponential in the product of the plant and the specification sizes [7]. In order to identify a special case where the complexity may be more manageable, we restrict attention to the class of deterministic plants. In this case, the complexity of verifying existence of a controller turns out to be polynomial, whereas that of performing its synthesis is singly exponential. We establish state-controllability (SC) together with state-recognizability (SR) as a necessary and sufficient condition for the existence of a control. The notion of SC was introduced in [8] as an existence condition for the same problem under the restriction of complete observability of events; and it generalizes the notion of language-controllability (LC) from the setting of language-control to bisimilarity-control. In the presence of partial observation, a supervisor is required to be observation-compatible (also called M-compatible), and the additional condition of SR is needed for the existence of such a supervisor. The property of SR is same as bisimilarity with such a system that can be transformed by state-mergers to a M-compatible system, without altering the bisimilarity of the control it exercises. SR generalizes the notion of language-recognizability [1] in a similar manner as SC generalizes LC. We show that SR is polynomially verifiable, and also present an exponential complexity algorithm for synthesizing of a bisimilarity enforcing Supervisor.
Comparative Estimation of Coverage between National Immunization Program Vaccines and Non-NIP Vaccines in Korea

This study aimed to describe the differences in vaccination coverage between National Immunization Program (NIP) vaccines and non-NIP vaccines in Korea and to identify factors affecting the difference. Nationwide face-to-face interview-based questionnaire survey among randomly selected 4,374 participants aged 7-83 months was conducted. Vaccination coverage analyzed according to the birth cohorts, geographic areas, and socio-demographic characteristics. We found that NIP vaccines recorded higher primary vaccination coverage compared to non-NIP vaccines (95.9%-100% vs 30.7%-85.4%). The highest rate was Haemophilus influenzae type b (Hib) vaccine (85.4%), which was introduced in 1996, and the lowest rate was rotavirus vaccine (30.7%), which was introduced recently. On multivariate analysis, having a sibling were significantly associated with lower uptake of Hib vaccine, pneumococcal conjugate vaccine (PCV), and rotavirus vaccine; while, older mother's age and attendance to daycare center were significantly associated with lower uptake of PCV and rotavirus vaccine (P < 0.001). We found differences in the vaccine coverage rate between NIP vaccines and non-NIP vaccines; and the data suggests potential disparity in accessing non-NIP vaccines in Korea. Expansion of NIP to include non-NIP vaccines can provide better protection against the diseases through increased coverage.
A cutaneous feeling display using suction pressure

In this paper, we propose a novel tactile display by controlling suction pressure. The method is based on our discovery of an illusion that pulling a skin through a hole creates a sensation as if a stick is pushing the skin. Based on this property of perception and multi-primitive stimulation method, we confirmed that we could produce tactile sensation from concentrated pressure to smooth surface by a sparse array of suction holes. We show the principle of the tactile display and experimental results that support the principle.
A Model-Based Design Process for the SegBus Distributed Architecture

We discuss a design process for a custom distributed platform, namely the SegBus segmented bus architecture. The main emphasis of this work is on how different steps of the process are interconnected and how they are supported by the associated tool chain. We place the SegBus design process in the context of the model-driven architecture (MDA) paradigm, in order to provide graphical editors that allow the editing of the specification at different abstraction levels and automated transformations that refine the specification towards implementation. We customize the Unified Modeling Language (UML) to graphically specify different artifacts produced in the process and we employ UML-based tools to implement transformations between these artifacts. In addition, we adopt as application model the packet SDF (PSDF), an extension of the synchronous data flow (SDF) diagrams. By modeling the operational semantics for the SegBus architecture, the PSDF facilitates the mapping of the application on the architecture. From the mapping process we obtain the requirements for the structural VHDL code of the application-platform instance realization and the control code for the arbiters of the architecture.
Risk Management Under a Two-Factor Model of the Term Structure of Interest Rates

This paper presents several applications to interest rate risk management based on a two-factor continuous-time model of the term structure of interest rates previously presented in Moreno (1996). This model assumes that default free discount bond prices are determined by the time to maturity and two factors, the long-term interest rate and the spread (difference between the long-term rate and the short-term (instantaneous) riskless rate). Several new measures of ``generalized duration" are presented and applied in different situations in order to manage market risk and yield curve risk. By means of these measures, we are able to compute the hedging ratios that allows us to immunize a bond portfolio by means of options on bonds. Focusing on the hedging problem, it is shown that these new measures allow us to immunize a bond portfolio against changes (parallel and/or in the slope) in the yield curve. Finally, a proposal of solution of the limitations of conventional duration by means of these new measures is presented and illustrated numerically.
The Institute for Systems Research Study of Olsr for Real-time Media Streaming over 802.11 Wireless Network in Software Emulation Environment Study of Olsr for Real-time Media Streaming over 802.11 Wireless Network in Software Emulation Environment

Isr develops, applies and teaches advanced methodologies of design and analysis to solve complex, hierarchical, heterogeneous and dynamic problems of engineering technology and systems for industry and government. Isr is a permanent institute of the university of maryland, within the a. James clark school of engineering. It is a graduated national science foundation engineering research center. Abstract—In this paper we present a setup to study the real-time traffic carrying performance of Optimized Link State Routing (OLSR) protocol using software emulation. We emulate the IEEE 802.11 MAC/PHY using the EMANE software emu-lator, on a cluster of machines, for different multi-hop wireless scenarios. As an instance of real-world usage scenario, we study the performance of real-time streaming media over a mesh network supported by OLSR. In particular, we study the effect of mobility and background traffic on carried load and jitter. We propose to extend this emulation setup to test the real-time performance of prototype routing protocols such as Stable Path Topology Control (SPTC) and other real-time applications.
Orphans and other vulnerable children: what role for social protection ?

Recent estimates have provided unprecedented numbers of orphans, and vulnerable children, either brought about because of the HIV/AIDS epidemic, or carriers themselves of HIV infections, a relentless growth which has precipitated a multifaceted care burden, that will too, grow for the next twenty years. This report records the proceedings of the Conference"Orphans and Other Vulnerable Children", which sought to promote awareness of the extent of this crisis, and, to probe the role of social protection in implementing a balanced response. The social protection framework for working with orphans, and vulnerable children shaped the conference agenda. Provision of appropriate risk management instruments is crucial for lasting poverty reduction, while programs to reduce the vulnerability of orphans, and other children, should play an integral role in any national development strategy, in the context of the HIV/AIDS epidemic. Building community capacity will constitute the centerpiece of any feasible response. Within a realistic framework, programs must spread, and scale up, to address the vast, and growing need.
The European Bioinformatics Institute in 2016: Data growth and integration

New technologies are revolutionising biological research and its applications by making it easier and cheaper to generate ever-greater volumes and types of data. In response, the services and infrastructure of the European Bioinformatics Institute (EMBL-EBI, www.ebi.ac.uk) are continually expanding: total disk capacity increases significantly every year to keep pace with demand (75 petabytes as of December 2015), and interoperability between resources remains a strategic priority. Since 2014 we have launched two new resources: the European Variation Archive for genetic variation data and EMPIAR for two-dimensional electron microscopy data, as well as a Resource Description Framework platform. We also launched the Embassy Cloud service, which allows users to run large analyses in a virtual environment next to EMBL-EBI's vast public data resources.
Depth From Water Reflection

The scene in a water reflection image often exhibits bilateral symmetry. In this paper, we design a framework to reconstruct the depth from a single water reflection image. This problem can be regarded as a special case of two-view stereo vision. It is challenging to obtain correspondences from the real scene and the mirror scene due to their large appearance difference. We first propose an appearance adaptation method to transform the appearance of the mirror scene so that it is much closer to the real scene. We then present a stereo matching algorithm to obtain the disparity map of the real scene. Compared with other depth-from-symmetry work that deals with man-made objects, our algorithm can recover the depth maps of a variety of scenes, where both natural and man-made objects may exist.
Methamphetamine-Associated Psychosis and Treatment With Haloperidol and Risperidone: A Pilot Study

Background Different studies have suggested that antipsychotic medications of the first generation have better effectiveness for the treatment of psychotic symptoms compared with antipsychotic medications of the second generation. Objectives The current study was the first pilot study in Iran that compared Haloperidol with Risperidone in the treatment of positive symptoms of psychosis among a group of methamphetamine-dependent patients. Materials and Methods This randomized clinical trial was designed and conducted in 2012. Overall, 44 patients who met the diagnostic and statistical manual of mental disorders, fourth edition-text revised (DSM.IV-TR) criteria for methamphetamine-associated psychosis (MAP) and were hospitalized at Razi psychiatric hospital in Tehran were selected. Patients (1: 1) were randomly divided to two groups. Overall, 22 subjects received Haloperidol (5 - 20 mg) and 22 subjects received Risperidone (2 - 8 mg). All subjects were assessed at baseline, during three consecutive weeks of treatment and one week after treatment (i.e., follow-up). Scale of assessment of positive symptoms (SAPS) was completed for each subject. Results The study findings indicated that both Haloperidol (< 0.05) and Risperidone (< 0.05) were similarly applicable in the treatment of MAP but no differential effectiveness was found between the two medications. The treatment effects of both medications increased in the first two weeks of treatment and remained stable in the second two weeks. Conclusions Risperidone and Haloperidol are two effective antipsychotic medications for the treatment of positive symptoms of MAP but other aspects of these two neuroleptic medications such as the long-term treatment effects should be studied. Further studies with more samples and longer follow-ups are suggested.
