An environment for building, exploring and querying academic social networks

Social network analysis aims at uncovering and understanding the structures and patterns resulting from social interactions among individuals and organizations engaged in a common activity. Since the early days of the field, networks are modeled as graphs modeling social actors and the relations between them. The field has become very active with the maturity of computational machinery to handle large-scale graphs, and, more recently, the automated gathering of social data. We introduce ReaSoN: a comprehensive set of tools for visualizing and exploring social networks resulting from academic research. In doing so, ReaSoN contributes to the understanding as well as fostering of the social networks underlying academic research. We describe the infrastructure, visualizations and analysis provided in our system, as well as the process of extracting the social networks which are latent in bibliographic and citation databases.
A system for locating users of WLAN using statistical mapping in indoor and outdoor environment-LOIDS

Recent developments in wireless Local Area Networks made usage of wireless technology efficiently. The availability of portable, light weight, hand held computing devices and high speed wireless local area network enabled users to remain connected while moving in indoor or outdoor environment. Wireless local area network has a wide range of utilization while moving from one location to another location. When a user is moving from one location to another, how the other user knows about the required station inside the WLAN. For that we designed and implemented a system to locate a mobile user inside the wireless local area network with the help of RSSI. We designed four different architectures and used statistical mapping. These architectures are based on statistical or we can say manual configuration of radio maps of indoor and outdoor location with the help of available Sniffer based and cluster based techniques. We were also found a better location of a mobile user in WLAN with the help of Pamvotis WLAN simulator. We tested this work in indoor and outdoor environment with different locations.
The Genome and Methylome of a Subsocial Small Carpenter Bee, Ceratina calcarata

Understanding the evolution of animal societies, considered to be a major transition in evolution, is a key topic in evolutionary biology. Recently, new gateways for understanding social evolution have opened up due to advances in genomics, allowing for unprecedented opportunities in studying social behavior on a molecular level. In particular, highly eusocial insect species (caste-containing societies with nonreproductives that care for siblings) have taken center stage in studies of the molecular evolution of sociality. Despite advances in genomic studies of both solitary and eusocial insects, we still lack genomic resources for early insect societies. To study the genetic basis of social traits requires comparison of genomes from a diversity of organisms ranging from solitary to complex social forms. Here we present the genome of a subsocial bee, Ceratina calcarata. This study begins to address the types of genomic changes associated with the earliest origins of simple sociality using the small carpenter bee. Genes associated with lipid transport and DNA recombination have undergone positive selection in C. calcarata relative to other bee lineages. Furthermore, we provide the first methylome of a noneusocial bee. Ceratina calcarata contains the complete enzymatic toolkit for DNA methylation. As in the honey bee and many other holometabolous insects, DNA methylation is targeted to exons. The addition of this genome allows for new lines of research into the genetic and epigenetic precursors to complex social behaviors.
The luminosity--bias relation from filaments in the Sloan Digital Sky Survey Data Release Four

We compare quantitative estimates of the filamentarity of the galaxy distribution in seven nearly two-dimensional sections from the survey against the predictions ofcold dark matter (�CDM) N-body simulations. The filamentarity of the actual galaxy distribution is known to be luminosity-dependent. It is also known that the filamentarity of the simulated galaxy distribution is highly sensitive to the bias, and the simulations are consistent with the data for only a narrow range of bias. We apply this feature to several volume-limited subsamples with different luminosities to determine a luminosity-bias relation. The relative bias b/b ∗ as a function of the luminosity ratio L/L ∗ is found to be well described by a straight line b/b ∗ = A + B (L/L ∗ ) with A = 0.833 ± 0.009 and B = 0.171 ± 0.009. Comparing with the earlier works, all of which use ratios of the two-point statistics, we find that our results are consistent with Norberg et al. and Tegmark et al., while a steeper luminosity dependence found by Benoist et al. is inconsistent.
Analysis of Multipath Effects on Accuracy of Range Estimation Using Received Signal Strength Indicator

Received signal strength indicator(RSSI) is considered as a good estimator of link quality and is also used to estimate the range between nodes in WSN. This paper analyzed the multipath effects on accuracy of range estimation using RSSI. Experiments are carried on in different environments. Through the analysis of experiments results, we can draw the conclusion that the estimation accuracy is getting worse with longer distance. And the multipath effects of enclosure environment also introduce estimation error when using RSSI.
Electromagnetic and Thermal Design of a Linear Actuator Using Output Polynomial Mapping

This paper describes the optimization methodology used in the design of a tubular slotted PM actuator for industrial applications. A time effective optimization procedure is obtained by considering simple analytical design equations in coherence with 2D finite element analysis as means to establish the various design variables. The original optimization problem is replaced by a surrogate, which is updated/improved iteratively by means of a space mapping based technique. Its application for solving coupled magnetic-thermal design problems for electric machines is a rather unexplored topic. The optimization is performed in a multi-physics environment, since both electromagnetic and thermal models are created and used in the optimization routine
Radiology workflow-based monitoring dashboard in a heterogeneous environment

Radiology departments could benefit from the digital dashboards which integrate and visualize information reflecting workflow state. However, the heterogeneous environment in radiology prevents an integrated overall view of the process. The objective of this study is to design and develop a workflow-based dashboard in a heterogeneous environment to help the radiology administrators and managers monitor the state of the work flow in real time. Firstly, we propose to use workflow management method to implement the system integration. Then a real-time monitoring dashboard which analyzed data from workflow management system integrated with information in other radiology systems is designed and developed. A use case implementation is carried out in Huzhou Central hospital of China. The dashboard is well accepted by the radiology administrators and managers in the hospital who lack real-time workflow monitoring tools in a heterogeneous environment. This work presents a new perspective on radiology department management, and can be viewed as an initial endeavor for introducing workflow management technology in healthcare.
Virtual Simulator for Design of Mobile Robot Control and Navigation Systems

The development of control systems for independent mobile robots has appear as a great challenge for the researchers until the current days. Different platform for the project of control system for independent mobile robots come being used in diverse research areas. Per many years the researchers have constructed control systems that present an intelligent behavior in controlled environments, with ideal situations, but that normally does not keep the same performance in the real world. Innumerable systems of control exist to be used in the real world, but generally these systems are limited and they do not present an independent or intelligent behavior. Diverse possible applications for the mobile robots already exist. In the transport, monitoring, inspection, cleanness of houses, space exploration, aid the physical deficient, among others. However, the independent mobile robots had not yet caused much impact in domestic or industrial applications, mainly had the lack of a system with robust, trustworthy and flexible control that it would allow these robots operated in dynamic environments, less structuralized, and inhabited by human beings. The development of a mobile robotic model system with open architecture and flexible control, with robust control system, that incorporates what exists of modern in terms of embedded hardware technology and that makes possible the operation of a mobile robotic systems in a real world environment is one of the motivations of this work. The locomotion planning, under some types of restrictions, is a very vast field of research in the area of the mobile robotics (Graf, 2001). The basic planning of trajectory for the mobile robots imply the determination of a way in the space-C (configuration space) between an initial configuration of the robot and a final configuration, in such a way that the robot does not collide with no obstacle in the environment, and that the planned movement is consistent with the kinematic restrictions of the vehicle. In this context, one of the boarded points in this work was development of a trajectory calculator for mobile robots. One of the main motivations of this work is to propitiate a virtual environment that facilitates the development of archetypes of embedded systems, emphasizing the implementation 26
Testing web database applications

Commercial, scientific, and social activities are increasingly becoming dependent on Web database applications. New testing techniques that handle the unique features of these systems are needed. To that end, we have extended AGENDA, a tool set for testing relational database applications, to test web database applications. Application source code is analyzed to extract relevant information about the URLs and their parameters. This information is used to construct and simplify a graph in which nodes represent URLs and edges represent links between URLs. A set of paths through the graph is selected and test cases are generated for each path. The extracted information about the parameters to each URL (e.g., values that an application user would enter into a form), is used to guide AGENDA to generate inputs for the URLs. The URLs on a path and their inputs are stored in an XML file, which is then automatically executed. The current implementation is targeted toward web applications written as Java Servlets and uses an algorithm based on cyclomatic complexity to generate paths. Preliminary empirically evaluation based on the TPC-W benchmark is presented.
Approaches to Model Query Interactions

A typical database workload consists of several query instances of different query types running concurrently. The execution of each query may interact with the execution of the other queries. It is well known that such interactions can have a significant impact on database system performance. In this article we propose three new approaches to model and measure query instance and query type interactions. Our approaches require no prior assumptions about the internal aspects of the database system, making it non intrusive, namely, portable across systems. Furthermore, to demonstrate the profit of exploiting query interactions, we have developed a novel interaction-aware query scheduler for online workloads, called Intelligent Scheduler for Multiple-query Execution Ordering (ISO, for short). In order to verify the efficiency of the proposed approaches for measuring query interaction and of IOS, an experimental evaluation using TPC-H workloads running on PostgreSQL has been done. The results show that the proposed approach has potential to improve the efficiency of database tuning tools.
Text mining approach for WSI in QA systems through relation construction

The paper attempts to identify the exact sense of the word through a process of establishing relations between similar words in the sample ontology. The philosophy relates to analysing the variance in sense among similar words with the help of a data mining tool to arrive at the exact sense of the target word as part of a question answering system. The focus spreads to derive new information from data and create patterns across datasets. The semantic relation among the words is calculated by assigning weights to investigate the variance and land at the exact sense. The distribution factor accrued from the manipulation of assigned weights reveals the significance of training to arrive at a better grading. The performance evaluated in terms of precision and accuracy exhibits the suitability of the proposed approach for use in the real world applications.
Wh-fronting (in Hungarian) Is Not Focus-fronting Wh-fronting in Language X Is Actually Just Focus-fronting

1. Introduction Across many languages, wh-questions bear extensive structural similarities to (what could be pre-theoretically dubbed) 'focus-constructions'. For this reason, linguists have often sought to identify some shared semantic or pragmatic property of these constructions, which might ultimately explain their structural affinities. 2 A common claim in this literature is that the parallels between wh-questions and focus-constructions are due to the fact that, in some languages, wh-questions obligatorily contain focus-constructions, a requirement that is, in turn, due to wh-operators being universally 'focused' (in some sense). The widespread acceptance of this claim has even lead some linguists to propose that obligatory wh-fronting in some languages is – contrary to first appearances – not due to a rule of 'wh-movement' as found in English, but simply reflects an independent requirement that 'focused' phrases be fronted (cf. Although this idea has by now been absorbed into the field's collective wisdom, it is actually rather difficult to state precisely what semantic/pragmatic properties wh-questions and focus-structures share, a fact that explicitly surfaces in early discussions of the proposal (Horvath 1986). To illustrate the point, let us consider those accounts which claim that obligatory wh-fronting in some languages is merely a species of a more general 'focus-fronting' rule. Typically, the logic of such an account runs as follows. (a) Language X requires that (non-wh) phrases bearing 'focus' (in some sense) must be fronted to position Y. (b) Wh-operators in the wh-questions of language X must be fronted to position Y. (c) Wh-operators in wh-questions universally bear 'focus' (in some sense). (d) Therefore, given (1a) above, the obligatory 'focus' of the wh-operators (1c) is sufficient to explain their obligatory fronting in wh-questions (1b). Given the schematization in (1), it is apparent that accounts of this form can only succeed if the term 'focus' in (1c) is used with the same sense as it is in (1a). That is, accounts of this type 1 I wish to thank Anikó Lipták and Marta Abrusan, both for their Hungarian judgments and for their discussion of the issues this paper concerns. Any errors are, of course, entirely my own. It should also be acknowledged here that many of the key empirical observations in this paper were already noted in a different context by Kiss (1998) and Horvath (2000, 2005). However, neither author discusses the consequences that these facts hold for the general theory of wh-fronting. 2 The following is a limited …
Tailoring Claims Analysis to the design and deployment of digital libraries : a case study

In a sophisticated system such as a digital library, design decisions made early in the design process, or at different levels – from software architecture to information content – have consequences for the design of the user interface. There is a need for tools that help developers evaluate the usability of digital library interfaces as early as possible in the design process. The work reported here has aimed to achieve two main objectives: to develop an evaluation techniques that gives useful leverage on deep design issues for digital libraries, and to overcome the gulf between usability researchers and library practitioners, such that the technique developed is usable by practitioners. Claims analysis was identified as a suitable starting point for the work. This is a usability evaluation method that specifically examines the effect of the design on the user of the interface. Four linked case studies, each further developing the approach, have been conducted. These have involved developers of two large digital library projects. The resulting technique gives support to the activity of generating scenarios which describe the context of use and encapsulate models of human computer interaction and the information seeking process. The analysis of the design rationale makes use of these scenarios to walkthrough the user activity, to consider the effect on the users’ goals and understanding.
Ca2+-Independent Protein Kinase C Apl II Mediates the Serotonin-Induced Facilitation at Depressed AplysiaSensorimotor Synapses

At nondepressed Aplysia sensory to motor synapses, serotonin (5-HT) facilitates transmitter release primarily through a protein kinase A pathway. In contrast, at depressedAplysia sensory to motor synapses, 5-HT facilitates transmitter release primarily through a protein kinase C (PKC)-dependent pathway. It is known that only two phorbol ester-activated PKC isoforms, the Ca2+-dependent PKC Apl I and the Ca2+-independent PKC Apl II, exist in the Aplysia nervous system. For the first time, we have now been able to functionally determine which isoform of PKC is involved in a particular form of plasticity. We microinjected cultured sensorimotor pairs of neurons with various PKC constructs tagged with the enhanced green fluorescent protein as a reporter for successful plasmid expression. Our results demonstrate that short-term facilitation of depressed synapses is mediated by PKC Apl II. Dominant-negative PKC Apl II, but not dominant-negative PKC Apl I, disrupted the normal kinetics of 5-HT-induced facilitation by completely blocking its rapid onset. This effect was specific to depressed synapses, because dominant-negative PKC Apl II did not inhibit 5-HT-mediated facilitation of nondepressed synapses. Our results suggest that not only different signal transduction pathways but also different isoforms of a specific cascade may mediate physiological responses according to the state of a synapse.
Longitudinal Evaluation of Cognitive Functioning in Young Children with Type 1 Diabetes over 18 Months

Abstract Objectives: Decrements in cognitive function may already be evident in young children with type 1 diabetes (T1D). Here we report prospectively acquired cognitive results over 18 months in a large cohort of young children with and without T1D. Methods: A total of 144 children with T1D (mean HbA1c: 7.9%) and 70 age-matched healthy controls (mean age both groups 8.5 years; median diabetes duration 3.9 years; mean age of onset 4.1 years) underwent neuropsychological testing at baseline and after 18-months of follow-up. We hypothesized that group differences observed at baseline would be more pronounced after 18 months, particularly in those T1D patients with greatest exposure to glycemic extremes. Results: Cognitive domain scores did not differ between groups at the 18 month testing session and did not change differently between groups over the follow-up period. However, within the T1D group, a history of diabetic ketoacidosis (DKA) was correlated with lower Verbal IQ and greater hyperglycemia exposure (HbA1c area under the curve) was inversely correlated to executive functions test performance. In addition, those with a history of both types of exposure performed most poorly on measures of executive function. Conclusions: The subtle cognitive differences between T1D children and nondiabetic controls observed at baseline were not observed 18 months later. Within the T1D group, as at baseline, relationships between cognition (Verbal IQ and executive functions) and glycemic variables (chronic hyperglycemia and DKA history) were evident. Continued longitudinal study of this T1D cohort and their carefully matched healthy comparison group is planned. (JINS, 2016, 21, 293–302)
Auditory Motion Information Drives Visual Motion Perception

Background Vision provides the most salient information with regard to the stimulus motion. However, it has recently been demonstrated that static visual stimuli are perceived as moving laterally by alternating left-right sound sources. The underlying mechanism of this phenomenon remains unclear; it has not yet been determined whether auditory motion signals, rather than auditory positional signals, can directly contribute to visual motion perception. Methodology/Principal Findings Static visual flashes were presented at retinal locations outside the fovea together with a lateral auditory motion provided by a virtual stereo noise source smoothly shifting in the horizontal plane. The flash appeared to move by means of the auditory motion when the spatiotemporal position of the flashes was in the middle of the auditory motion trajectory. Furthermore, the lateral auditory motion altered visual motion perception in a global motion display where different localized motion signals of multiple visual stimuli were combined to produce a coherent visual motion perception. Conclusions/Significance These findings suggest there exist direct interactions between auditory and visual motion signals, and that there might be common neural substrates for auditory and visual motion processing.
Participatory budgeting, austerity and institutions of democracy

Participatory budgeting operates in approximately 1500 cities across the globe. Often these projects are used in attempts to make city government more democratic. The growing popularity of participatory budgeting also reflects scholarly concerns about elite interests dominating policy-making to the extent that democratic institutions principally serve legitimation purposes. This paper examines the implementation and evolution of participatory budgeting in the City of Vallejo, California, following its 2008 chapter 9 bankruptcy. The City of Vallejo introduced participatory budgeting as part of a broader collection of reforms implemented to restructure the city budget and re-legitimate Vallejo’s city government. Participatory budgeting introduced new decision-making processes to the city and directed expenditures into new programs. An evaluation of the reforms and outcomes of Vallejo’s participatory budgeting reveals a picture of mixed success. Although participatory budgeting opened an important part of the city’s budget to democratic deliberation, the process became aligned with entrenched institutional interests. In conclusion the paper reflects on how the institutional structures of urban politics might limit the democratic potential of participatory budgeting.
Coupled-oscillator arrays for millimeter-wave power-combining and mode-locking

A theory describing arrays of coupled millimeter-wave oscillators is presented, and two important applications of such arrays-CW power combining, and a novel mode-locking technique for pulse generation-are discussed. Conditions for establishing mutual synchronization and the correct phase relationships have been investigated with the theory and verified experimentally using several prototype X-band arrays. <<ETX>>
