A Knowledge-Base Oriented Approach for Automatic Keyword Extraction

Automatic keyword extraction is an important subfield of information extraction process. It is a difficult task, where numerous different techniques and resources have been proposed. In this paper, we propose a generic approach to extract keyword from documents using encyclopedic knowledge. Our two-step approach first relies on a classification step for identifying candidate keywords followed by a learning-to-rank method depending on a user-defined keyword profile to order the candidates. The novelty of our approach relies on i) the usage of the keyword profile ii) generic features derived from Wikipedia categories and not necessarily related to the document content. We evaluate our system on keyword datasets and corpora from standard evaluation campaign and show that our system improves the global process of keyword extraction.
Continuous monitoring of the ground surface change in Sakurajima volcano using RADARSAT-2 data

We applied C-band SAR data acquired by RADARSAT-2 to examine ground surface changes in the active volcanic field. In the active volcano area, the observation of secondary disaster with rainfall is also important as well as direct influence by the volcanic eruption. By continuous monitoring, we generated a change detection image from the Spotlight mode data (1m resolution). By using the change detection images and also by field survey, sand movements with debris flow and ground surface change by eruption were extracted. We concluded that continuous monitoring using the SAR is effective for preventing volcanic disaster.
A critical appraisal of the maternal and child health scenario in a metropolitan city in India with reference to achievements of millennium development goals

Background: Post 2015, the Millennium Development Goals (MDGs) will undergo a transition to Sustainable Development Goals (SDGs). Therefore, it becomes necessary to assess the determinants influencing the present status of MDGs. This study was conducted to assess the progress, short comings related to the transition from MDGs to SDGs in a metropolitan city. It provides practical insights for extrapolating need based strategies related to the SDGs. Methods: Study was conducted in a metropolitan city, Mumbai. Situational analysis of the city was done using monthly and annual performance reports and key informant's interviews at city level. Qualitative analysis was done using thematic analysis. Results: The current infant mortality rate of Mumbai is 26.72 and under-five mortality rate is 38.7/1000 live births. The current MMR of mumbai is 88. The responses from the key informants’ spanned three major themes: Concerns and challenges; Good practices and schemes in pipeline; and Opportunities envisioned. Eight major challenging areas were identified. Opportunities are sustainable models of public-private partnership; Involvement of NGOs and AYUSH practitioners; and IT sector involvement, HMIS, e- governance, and Corporate Social Responsibility (CSR). Conclusions: Significant progress has been made in the field of maternal and child health (MCH), and sustained efforts are required. Maternal mortality figures may be illusive because of the effect of migration and referral cases. Socio-demographic issues of development need to be addressed through governance. Mechanism for intersectoral coordination, IT support, surveillance, and tracking of pregnant mothers needs to be developed. The linkage of MCH services with developmental programs needed.
Incoherent-coherent crossover and the pseudogap in Te-annealed superconducting 
Fe1+yTe1−xSex
 revealed by magnetotransport measurements

In this paper, we conducted various magnetotransport measurements on ${\mathrm{Fe}}_{1+y}{\mathrm{Te}}_{1\ensuremath{-}x}{\mathrm{Se}}_{x}$ single crystals from which excess iron was sufficiently removed. Our results revealed that crossover from the incoherent to the coherent electronic state and the opening of the pseudogap occur at high temperatures ($\ensuremath{\approx}150\phantom{\rule{0.28em}{0ex}}\mathrm{K}$ for $x=0.2$). This is accompanied by a more substantial pseudogap and the emergence of a phase with a multiband nature at lower temperatures (below $\ensuremath{\approx}50\phantom{\rule{0.28em}{0ex}}\mathrm{K}$ for $x=0.2$) before superconductivity sets in. A comparison of these results with those of the as-grown (nonsuperconducting) samples implies that the coherent state accompanied by the pseudogap is needed for the occurrence of superconductivity in this system.
Monolithic SiGe HBT variable gain amplifiers with a feedforward configuration for 5-GHz applications

Monolithic SiGe HBT variable gain amplifiers with a feedforward configuration have been newly developed for 5-GHz applications. For bias-current control, two types of the VGA have been made: one using a coupled-emitter resistor and the other using HBT-based current source. At 5.2 GHz, both of the VGAs achieve a dynamic gain-control range of 23 dB with the control-voltage range from 0.4 to 2.6 V. The gain-tuning sensitivity is 90 mV/dB. The VGAs with an emitter resistor and a current source produce a maximum gain of 8.8 dB and 8.2 dB, respectively. At V CTRL=2.4 V, an 1-dB compression output power P1-dB and dc bias current are 0 dBm and 59 mA in the VGA with an emitter resistor and -1.8 dBm and 71mA in that with a constant current source, respectively
ENGINEERING ORIENTED HEME PROTEIN MAQUETTE MONOLAYERS THROUGH SURFACE RESIDUE CHARGE DISTRIBUTION PATTERNS

We have designed and synthesized four-α-helix-bundle proteins that accommodate heme groups to act as molecular “maquettes” of more complex natural electron-transfer proteins. These bundles can be oriented at an air−water interface and transferred onto solid surfaces to facilitate the exploration of the factors that govern biological electron transfer. We find that the orientation of these maquettes on an air−water interface can be controlled by choosing the distribution of charged amino acids along the sides of the helices exposed to water. The four α-helices were assembled either as two subunits, where each subunit consists of two α-helices linked by a terminal cysteine disulfide bond, or as a single, four-helix covalent unit consisting of two helix−loop−helix molecules linked by a terminal cysteine. In either case, when each α-helix contains both positively charged lysines and negatively charged glutamates, addition of the heme binding bundles to an air−water interface causes them to open up and lie on .
Temporal Integration in Visual Memory

Iconic memory has often been likened to a sensory store whose contents drain away rapidly as soon as the inducing stimulus is turned off. Instances of short-lived visible persistence have been explained in terms of the decaying contents of iconic store. A fundamental requirement of this storage model is that strength of persistence should be a decreasing function of time elapsed since the cessation—not since the onset—of the inducing stimulation. That is, strength of visible persistence may be directly related—but not inversely related—to the duration of the inducing stimulus. Two complementary paradigms were utilized in the present studies. In the first paradigm performance was facilitated by visible persistence in that the task required the bridging of a temporal gap between two successive displays. In the second paradigm (forward visual masking by pattern), performance was impaired by lingering visible persistence of the temporally leading mask. Both paradigms yielded evidence of an inverse relationship between duration of inducing stimulus and duration of visible persistence. More specifically, in a task requiring temporal integration of a pattern displayed briefly in two successive portions, performance was severely impaired if the duration of the leading part exceeded about 100 msec. This suggests an inverse relationship between duration of inducing stimulus and duration of sensory persistence and allows the inference that visual persistence may be identified more fittingly with ongoing neural processes than with the decaying contents of an iconic store. In keeping with this suggestion, two experiments disconfirmed the conjecture that lack of temporal integration following long inducing stimuli could be ascribed to emergence of unitary form separately in the two portions of the display or to the triggering of some sort of discontinuity detection mechanism within the visual system. In added support of a "processing" model, two further studies showed that the severity of forward masking by pattern declines sharply as the duration of the leading mask is increased. This pattern of results is equally unsupportive of a storage theory of iconic persistence as of perceptual moment theory in any of its versions. This is so because both theories regard interstimulus interval rather than stimulus-onset asynchrony as the crucial factor in temporal integration. Neither can the results be explained in terms of receptor adaptation or of metacontrast suppression. The theory of inhibitory channel interactions can encompass the more prominent aspects of the results but fails to account for foveal suppression and for some crucial temporal effects.
Antibodies that protect humans against Plasmodium falciparum blood stages do not on their own inhibit parasite growth and invasion in vitro, but act in cooperation with monocytes

IgG extracted from the sera of African adults immune to malaria were injected intravenously into eight Plasmodium falciparum-infected nonimmune Thai patients. Clinical and parasitological improvement was reproducibly obtained in each case. After the disappearance of the transferred Ig, recrudescent parasites were equally susceptible to the same Ig preparation. High levels of antibodies to most parasite proteins were detected by Western blots in the receivers' sera (taken before transfer) as in the donors' Ig, thus indicating that the difference was qualitative rather than quantitative between donors and receivers. In vitro, the clinically effective Ig had no detectable inhibitory effect on either penetration or intra-erythrocytic development of the parasite. On the contrary, they sometimes increased parasite growth. In contrast, these IgG, as the receivers' Ig collected 4 d after transfer, but not those collected before transfer, proved able to exert an antibody-dependent cellular inhibitory (ADCI) effect in cooperation with normal blood monocytes. Results were consistent among the seven isolates studied in vitro, as with the recrudescent parasites. Thus, the results obtained in the ADCI assay correlate closely with clinical and parasitological observations.
Short-Term Effects of Strength and Plyometric Training on Sprint and Jump Performance in Professional Soccer Players

The purpose of this study was to compare the effects of combined strength and plyometric training with strength training alone on power-related measurements in professional soccer players. Subjects in the intervention team were randomly divided into 2 groups. Group ST (n = 6) performed heavy strength training twice a week for 7 weeks in addition to 6 to 8 soccer sessions a week. Group ST+P (n = 8) performed a plyometric training program in addition to the same training as the ST group. The control group (n = 7) performed 6 to 8 soccer sessions a week. Pretests and posttests were 1 repetition maximum (1RM) half squat, countermovement jump (CMJ), squat jump (SJ), 4-bounce test (4BT), peak power in half squat with 20 kg, 35 kg, and 50 kg (PP20, PP35, and PP50, respectively), sprint acceleration, peak sprint velocity, and total time on 40-m sprint. There were no significant differences between the ST+P group and ST group. Thus, the groups were pooled into 1 intervention group. The intervention group significantly improved in all measurements except CMJ, while the control group showed significant improvements only in PP20. There was a significant difference in relative improvement between the intervention group and control group in 1RM half squat, 4BT, and SJ. However, a significant difference between groups was not observed in PP20, PP35, sprint acceleration, peak sprinting velocity, and total time on 40-m sprint. The results suggest that there are no significant performance-enhancing effects of combining strength and plyometric training in professional soccer players concurrently performing 6 to 8 soccer sessions a week compared to strength training alone. However, heavy strength training leads to significant gains in strength and power-related measurements in professional soccer players.
HDL Oxidation Compromises its Influence on Paraoxonase-1 Secretion and its Capacity to Modulate Enzyme Activity

Objective—The purpose of this study was to analyze the consequences of HDL oxidation for paraoxonase-1 metabolism and function. Methods and Results—HDL was oxidized with AAPH, copper ions, and hypochlorite. Secretion studies were performed using human paraoxonase-1–transfected cells lines and primary rat hepatocytes. Stability studies were performed with recombinant paraoxonase. Conditioned medium had significantly reduced paraoxonase-1 when Cu or AAPH-oxidized HDL was the acceptor complex (P<0.01); reduction was dose-dependent on the degree of oxidation. Oxidized HDL had a reduced capacity to stabilize/improve activity of secreted paraoxonase-1. Reduced secretion could not be attributed to enzyme inactivation by lipoperoxides, reduced binding affinity of HDL, or oxidation of the lipid component alone. Hypochlorite oxidation of HDL did not modify HDL-mediated paraoxonase-1 release, but activity of HDL-associated paraoxonase-1 was particularly sensitive to such treatment. Conclusions—AAPH and copper, but not hypochlorite, oxidation of HDL compromises its ability to promote release of paraoxonase-1 and stabilize enzyme activity. HDL-associated paraoxonase-1 is highly sensitive to hypochlorite. Reducing paraoxonase-1 renders HDL susceptible to oxidation, which may compromise HDL function. It provides a novel example at the HDL level of the detrimental effects of oxidative stress, and underlines the need for further evaluation of the consequences of HDL oxidation.
Racism and Oral Health Outcomes among Pregnant Canadian Aboriginal Women

This study assessed links between racism and oral health outcomes among pregnant Canadian Aboriginal women. Baseline data were analyzed for 541 First Nations (94.6%) and Métis (5.4%) women in an early childhood caries preventive trial conducted in urban and on-reserve communities in Ontario and Manitoba. One-third of participants experienced racism in the past year determined by the Measure of Indigenous Racism Experience. In logistic regressions, outcomes significantly associated with incidents of racism included: wearing dentures, off-reserve dental care, asked to pay for dental services, perceived need for preventive care, flossing more than once daily, having fewer than 21 natural teeth, fear of going to dentist, never received orthodontic treatment and perceived impact of oral conditions on quality of life. In the context of dental care, racism experienced by Aboriginal women can be a barrier to accessing services. Programs and policies should address racism’s insidious effects on both mothers’ and children’s oral health outcomes.
Attitude synchronization of rigid bodies via distributed control

In this paper, we focus on one of the motion coordination problems called attitude synchronization. We propose a continuous-time protocol to align the states of a network of agents evolving in the space of rotations SO(3). Our work is related to the Riemannian consensus, which is a general extension of classical consensus algorithms to Riemannian manifolds. The existing algorithms have the problem of either lack of global convergence or slow convergence rate. We show how to modify them so that the states of the agents can be aligned from almost any initial condition and also in faster convergence speed.
Myosin Iβ Is Located at Tip Link Anchors in Vestibular Hair Bundles

Recent studies have suggested that myosin Iβ mediates the adaptation of mechanoelectrical transduction in vestibular hair cells. An important prediction of this hypothesis is that myosin Iβ should be found in the side insertional plaque, an osmiophilic hair bundle structure that anchors tip links and is thought to house the adaptation motor. To determine whether myosin Iβ was situated properly to perform adaptation, we used immunofluorescence and immunoelectron microscopy with the monoclonal antibody mT2 to examine the distribution of myosin Iβ in hair bundles of the bullfrog utricle. Although utricular hair cells differ in their rates and extent of adaptation [Baird RA (1994) Comparative transduction mechanisms of hair cells in the bullfrog utriculus. II. Sensitivity and response dynamics to hair bundle displacement. J Neurophysiol 71:685–705. ], myosin Iβ was present in all hair bundles, regardless of adaptation kinetics. Confirming that, nevertheless, it was positioned properly to mediate adaptation, myosin Iβ was found at significantly higher levels in the side insertional plaque. Myosin Iβ was also present at elevated levels at the second tip link anchor of a hair bundle, the tip insertional plaque, found at the tip of a stereocilium. These data support myosin Iβ as the adaptation motor and are consistent with the suggestion that the motor serves to restore tension applied to transduction channels to an optimal level, albeit with different kinetics in different cell types.
Enriching reverse engineering through visual exploration of Android binaries

The appearance of the Android platform and its popularity has resulted in a sharp rise in the number of reported vulnerabilities and consequently in the number of mobile threats. Leveraging openness of Android app markets and the lack of security testing, malware authors commonly employ a suite of widely available tools to facilitate the app development. Analysis of individual apps for malware detection often requires understanding of app functionality and complex, time-consuming analysis of its behavior. Since tools tend to leave traces in the program structure, we can potentially use visual exploration of these artifacts to enrich reverse engineering of malware analysis. In this paper, we focus on this approach and investigate internal structure of Android executable files and their characteristics under various tools and development conditions. We show that the majority of obfuscation and optimization tools leave distinct artifacts that can be leveraged in Android binary analysis to trace origin of a malware sample on hand.
Micro-drive Array for Chronic in vivo Recording: Drive Fabrication

Chronic recording of large populations of neurons is a valuable technique for studying the function of neuronal circuits in awake behaving rats. Lightweight recording devices carrying a high density array of tetrodes allow for the simultaneous monitoring of the activity of tens to hundreds of individual neurons. Here we describe a protocol for the fabrication of a micro-drive array with twenty one independently movable micro-drives. This device has been used successfully to record from hippocampal and cortical neurons in our lab. We show how to prepare a custom designed, 3-D printed plastic base that will hold the micro-drives. We demonstrate how to construct the individual micro-drives and how to assemble the complete micro-drive array. Further preparation of the drive array for surgical implantation, such as the fabrication of tetrodes, loading of tetrodes into the drive array and gold-plating, is covered in a subsequent video article.
Trauma, Treatment, and Religion

Abstract When children and youth are traumatized, caretakers must attend to behavioral, cognitive, physiological, ecological and spiritual/existential aspects of their reactions. This article focuses on the latter facet of traumatization. The Hebrew Scriptures and the New Testament offer little about the traumatic symptoms of victims. Using many of the same sources, Fundamentalist Christians, Jews, mainline Christians and secularists may offer children different interpretations of the meaning of trauma events. Understanding these interpretations is crucial for children who develop symptoms which suggest a diagnosis of PTSD. Caretakers, other than mental health professionals, can understand and use various techniques explicated in the TREAT model for treatment of PTSD. Concepts discussed can be used, within a spiritual/existential framework, to support traumatized youngsters.
Towards capturing and preserving changes on the Web of Data

Existing Web archives aim to capture and preserve the changes of documents on the Web and provide data corpora of high value which are used in various areas (e.g. to optimise algorithms or to study the Zeitgeist of a generation). So far, the Web archives concentrate their efforts to capture the large Web of documents with periodic snapshot crawls. Little focus is drawn to preserve the continuously growing Web of Data and actually keeping track of the real frequency of changes. In this work we present our efforts to capture and archive the changes on the Web of Data. We describe our infrastructure and focus on evaluating strategies to accurately capture the changes of data and to also estimate the crawl time for a given set of URLs with the aim to optimally schedule the revising of URLs with limited resources.
Delineating the Tes Interaction Site in Zyxin and Studying Cellular Effects of Its Disruption

Focal adhesions are integrin-based structures that link the actin cytoskeleton and the extracellular matrix. They play an important role in various cellular functions such as cell signaling, cell motility and cell shape. To ensure and fine tune these different cellular functions, adhesions are regulated by a large number of proteins. The LIM domain protein zyxin localizes to focal adhesions where it participates in the regulation of the actin cytoskeleton. Because of its interactions with a variety of binding partners, zyxin has been proposed to act as a molecular scaffold. Here, we studied the interaction of zyxin with such a partner: Tes. Similar to zyxin, Tes harbors three highly conserved LIM domains of which the LIM1 domain directly interacts with zyxin. Using different zyxin variants in pull-down assays and ectopic recruitment experiments, we identified the Tes binding site in zyxin and showed that four highly conserved amino acids are crucial for its interaction with Tes. Based upon these findings, we used a zyxin mutant defective in Tes-binding to assess the functional consequences of abrogating the zyxin-Tes interaction in focal adhesions. Performing fluorescence recovery after photobleaching, we showed that zyxin recruits Tes to focal adhesions and modulates its turnover in these structures. However, we also provide evidence for zyxin-independent localization of Tes to focal adhesions. Zyxin increases focal adhesion numbers and reduces focal adhesion lifetimes, but does so independent of Tes. Quantitative analysis showed that the loss of interaction between zyxin and Tes affects the process of cell spreading. We conclude that zyxin influences focal adhesion dynamics, that it recruits Tes and that this interaction is functional in regulating cell spreading.
TripFromTV+: Exploiting social networks to arrange cut-price touristic packages

Tourists need advice about what to do in their trips. Bearing in mind the wide adoption and influence of social technologies from Web 2.0, we propose a tourism recommender system that offers tourist packages with two features: (i) they include the attractions and activities that best match the users' preferences, which are inferred from their profiles in social networks, and (ii) these packages have a reduced price if they are purchased by a number of users defined by the tourism providers registered in our system. To gather those many purchasers, we exploit the diffusion mechanisms of social networks, through which users make existing offers known to their contacts. Package providers benefit from novel profitable business options, while users enjoy personalized, permanently updated, reliable and on-move tourism offers, which can be accessed from fixed and handheld consumer devices.
