Segmentation of Mobile User Groups Based on Traffic Usage and Mobility Patterns

For the purpose of precision marketing, this paper aims to identify 2G user groups that are most likely to immigrate to 3G/4G mobile communication networks. Two dimensions of user behaviors are considered important for our purpose: traffic usage and mobility. User-labeled raw data is first extracted from the Gn interface. Such raw data is further processed to map each user into a probabilistic vector space, which characterizes the time-varying traffic usage and mobility patterns of the user. A K-Means clustering algorithm with Canopy approach is subsequently applied to the normalized vector space data for user group segmentation. The results indicate that the proposed method can be helpful for mobile operators to target valuable potential user groups in business promotion.
Nanomachine placement strategies for detecting Brownian molecules in nanonetworks

In this paper, we consider a nano-biosensor network composed of nano-to-micro scale biological machines distributed over a two-dimensional bounded area. The goal of the nano-biosensor network is to detect a target signal that propagates via Brownian motion in the monitoring area. Three simple nanomachine placement strategies are investigated: random, proportional, and regular placement. In the random placement, nanomachines are distributed randomly over the area. In the proportional placement, more nanomachines are placed where signals appear more frequently. In the regular placement, nanomachines are distributed to maintain a specific distance from adjacent nanomachines. Three placement strategies are evaluated through simulation based on the mean residence time which is defined as the average amount of time that a target signal stays in the monitoring area. Our simulation results show that the regular placement performs best when signal arrival locations follow normal distribution. Simulation results are also provided to show the impact of nanomachine failure on the mean residence time.
Auditory perceptual learning via decoded EEG neurofeedback: A novel paradigm

The present study used electrophysiological and behavioral measures to investigate the perception of an English stop consonant contrast by native English listeners and by native Dutch listeners who were highly proficient in English. A /ba/-/pa/ continuum was created from a naturally-produced /pa/ token by removing successive periods of aspiration, thus reducing the voice onset time (VOT). Whereas aspiration is a relevant cue for distinguishing voiced and unvoiced labial stop consonants (/b/ and /p/) in English, prevoicing is the primary cue used to distinguish between these categories in Dutch. In the electrophysiological experiment, participants listened to oddball sequences containing the standard /pa/ stimulus and one of three deviant stimuli, while the mismatch negativity (MMN) response was measured. Participants then completed an identification task on the same stimuli. Results revealed that native English participants were more sensitive to reductions in aspiration than native Dutch participants, as indicated by shifts in the category boundary and by differing within-group patterns of MMN responses and larger mean evoked potential amplitudes in the native English group for two of the three deviant stimuli. This between-group difference in the sensorineural processing of aspiration cues indicates that native language experience alters the way in which acoustic features of speech are processed in the auditory brain, even following extensive second-language training.

LiveBT: Providing Video-on-Demand Streaming Service over BitTorrent Systems

BitTorrent (BT) is one of the most popular Peer-to- Peer (P2P) protocols for delivering media files in the Internet today. Although BT is quite efficient for sharing and downloading files by using P2P swarming technique, the users have to download almost the whole media file before playing it. This is determined by the Rarest-Block-Download-First strategy of standard BT implementations, which is designed for fast delivery of files in the systems but not for streaming application. In this paper, we present LiveBT, a new protocol which supports video-on- demand streaming service and is totally compatible to the current BitTorrent protocol. LiveBT enables users to play hot movies shared in the BT systems smoothly just after 2-3 minutes of buffering time. We also develop the prototype of LiveBT and test the performance through the real BT download tasks of media files. By comparing our prototype with some popular BT clients claiming to support view-as- download service such as Bitcomet, we find that LiveBT spends a much shorter buffering time to play and achieves quite smooth playback performance.
Effect of Sorbed Water on Disintegrant Performance of Four Brands of Polacrilin Potassium NF

Polacrilin Potassium NF is a commonly used weak cation exchange resin disintegrant in pharmaceutical tablets. The objective of this research was to evaluate the effects of sorbed moisture on physical characteristics and disintegrant performance of four brands of Polacrilin Potassium NF. The disintegrants were stored in five different relative humidity chambers and their dynamic vapor adsorption–desorption analysis, effect of moisture on their compressibility, compactability, particle size, morphology, water uptake rate, and disintegration ability were studied. Moisture seemed to plasticize the disintegrants, reducing their yield pressures. However, certain optimum amount of moisture was found to be useful in increasing the compactablity of the tablets containing disintegrants. The tablets, however, lost their tensile strengths beyond this optimum moisture content. Moisture caused two brands of the disintegrants to swell; however, two other brands aggregated upon exposure to moisture. Swelling without aggregation increased the water uptake, and in turn the disintegrant performance. However, aggregation probably reduced the porosities of the disintegrants, reducing their water uptake rate and disintegrant performance. Different brands of Polacrilin Potassium NF differed in the abilities to withstand the effects of moisture on their functionality. Effect of moisture on disintegrant performance of Polacrilin Potassium NF needs to be considered before its use in tablets made by wet granulation.
Trading Privacy for Trust in Online Interactions

The need for privacy is broadly recognized by individuals, businesses, the government, the computer industry, and academic researchers. Examples are shown in Figure 1. The growing recognition of the importance of privacy is motivated not only by users’ sensitivity about their personal data. Other factors include business losses due to privacy violations, and enactments of federal and state privacy laws.
Minimum Number of Antennas Required to Satisfy Outage Probability in Massive MIMO Systems

In practical massive multiple-input multiple-output (MIMO) systems, determining the number of antennas to satisfy different service demands is an important issue. In this letter, in contrast to the traditional method using the Gaussian approximation, we present a novel approach to determine the number of antennas required to at least satisfy pre-specified outage probability requirements. By exploiting the statistical bounds on instantaneous MIMO capacity, we derive the equivalent problem of determining the number of antennas needed to satisfy outage probability constraints. Through solving the equivalent problem, we obtain the minimum number of antennas required under pre-specified outage probability requirements. Analysis and simulation results demonstrate that, in massive MIMO systems, the required minimum number of antennas obtained by the proposed method is more accurate than that obtained by the traditional method.
The Correlation of Achilles Tendinopathy and Body Mass Index

With this study we intend to determine if there is a correlation between body mass index (BMI) and Achilles tendon pathology. A retrospective chart review of 197 patients was performed with CPT codes of Achilles tendinosis/tendonitis. These 197 patients were then compared with 100 random new patient encounters excluding Achilles pathology, plantar fasciitis, and surgical consults. Statistical analysis was then performed to identify correlation of BMI to incidence of Achilles tendinosis compared with patients without Achilles pathology. A total of 197 Achilles tendon pathology patients (113 male, 84 female) were analyzed and had a mean age of 52.77 ± 11.8 years (21-82) with a BMI of 34.69 ± 7.54 (17.9-75.9). The control group had a mean age of 42.74 ± 12.1 years (21-78) and mean BMI of 30.56 ± 7.55 (19.7-61.5). A significant difference was found in mean BMI between the Achilles tendinopathy group versus the control group (P < .001). There was a very significant difference in age noted between the 2 cohorts (52.77 years vs 42.74 years, P < .001), perhaps reenforcing the involvement of age-related degenerative changes. In this study, patients with Achilles pathology exhibited a significantly higher BMI than non-Achilles patients (P < .001) even after accounting for age. Levels of Evidence: Prognostic Level II
Clingo = ASP + Control: Preliminary Report

We present the new ASP system clingo 4. Unlike its predecessors, being mere monolithic combinations of the grounder gringo with the solver clasp, the new clingo 4 series offers high-level constructs for realizing complex reasoning processes. Among others, such processes feature advanced forms of search, as in optimization or theory solving, or even interact with an environment, as in robotics or query-answering. Common to them is that the problem specification evolves during the reasoning process, either because data or constraints are added, deleted, or replaced. In fact, clingo 4 carries out such complex reasoning within a single integrated ASP grounding and solving process. This avoids redundancies in relaunching grounder and solver programs and benefits from the solver's learning capacities. clingo 4 accomplishes this by complementing ASP's declarative input language by control capacities expressed via the embedded scripting languages lua and python. On the declarative side, clingo 4 offers a new directive that allows for structuring logic programs into named and parameterizable subprograms. The grounding and integration of these subprograms into the solving process is completely modular and fully controllable from the procedural side, viz. the scripting languages. By strictly separating logic and control programs, clingo 4 also abolishes the need for dedicated systems for incremental and reactive reasoning, like iclingo and oclingo, respectively, and its flexibility goes well beyond the advanced yet still rigid solving processes of the latter.
Fiber in the Treatment and Maintenance of Inflammatory Bowel Disease: A Systematic Review of Randomized Controlled Trials

Background:Dietary fiber may favorably influence fermentation, gastrointestinal inflammation, and disease progression in Crohn's disease, ulcerative colitis (UC), and pouchitis and offer an attractive therapeutic addition to pharmacological treatment. This systematic review appraised data from randomized controlled trials of fiber in the management of inflammatory bowel disease. Methods:The review followed Cochrane and PRISMA recommendations. Seven electronic databases were searched along with hand searching and contacting experts. Inclusion criteria were randomized controlled trials of the effects of fiber on clinical endpoints (primarily disease activity for treatment or maintenance) or physiological outcomes in patients with inflammatory bowel disease. Results:In total, 23 randomized controlled trials fulfilled the inclusion criteria (UC, 10; Crohn's disease, 12; and pouchitis, 1) recruiting 1296 patients. In UC, 3/10 studies reported fiber supplementation to benefit disease outcomes. In Crohn's disease, 0/12 studies and in pouchitis 1/1 study reported a benefit on disease activity. Despite this, a number of studies reported favorable intragroup effects on physiological outcomes including fecal butyrate, fecal calprotectin, inflammatory cytokines, microbiota, and gastrointestinal symptom indices. Meta-analysis was not possible. Conclusions:There is limited weak evidence for the efficacy of fiber in improving disease outcomes in UC and pouchitis. The potential antiinflammatory role of fiber is intriguing and merits further investigation in adequately powered clinical trials. Excluding overt gastrointestinal obstruction, there was no evidence that fiber intake should be restricted in patients with inflammatory bowel disease.
Economic Performance and Political Trust: The impact of the financial crisis on European citizens

ABSTRACT Trust links ordinary citizens to the institutions that are intended to represent them, and thereby enhances both the legitimacy and the effectiveness of democratic government. In this article we investigate whether economic performance affects political trust and if the 2007–2008 financial crisis has decreased confidence levels due to the severity of its consequences. We employ multilevel modeling to analyze data from 25 European countries taken from the European Social Survey, combined with economic indicators from the World Bank and the international Monetary Fund. Our results show that economic performance is an important decider of people's levels of trust. We are also able to conclude that the financial crisis has reduced citizen's trust in political institutions in those countries where the crisis has had a severe impact on the economy.
Handbook of Dialogical Self Theory: Positioning in the dialogical self: recent advances in theory construction

[Extract] The literature on the dialogical self has grown significantly over the past two decades. The two guiding metaphors of a dialogical approach, namely that the self takes the form of both a 'conversation' and a 'mini-society', have been inspirational for researchers working across many topics in social, cultural and clinical psychology, and in neighbouring social sciences (e.g. Barresi 2002; Bhatia and Ram 2001; Chandler 2004; Fogel et al 2002; Gieser 2006; Hermans 2001; Hermans and Dimaggio 2004; Hermans and Hermans-Konopka 2010; Hermans and Kempen 1 993; Hevern 2004; Josephs 2002; Lewis. 2002; Lysaker 2006; Raggatt 2000, 2006; Sampson 1993; Stiles 1999; Tappan 2005). Fundamental to dialogical self theory (DST) is the proposition that the self has extension in both space and time through processes of positioning. Inspired particularly by William James (1890), Mikhail Bakhtin (1981, 1984) and George Herbert Mead (1934), Hermans (2001) has conceptualized the dialogical self as an extended 'position repertoire'. The repertoire contains a variety of interacting 'internal positions' (e.g. I as adventurer, I as pessimist), 'external positions' (e.g. the imagined voice of my father), and 'outside' positions (e.g. interlocutors, significant others, groups). In this dynamic arrangement, positioning processes are at play on multiple levels: in our 'self-talk', in our relationships, in the social order we inhabit, and in our cultural activities. As the engine of DST, therefore, the concept of positioning has a broad range of convenience with applications at different levels of engagement. Because of this breadth, an integrated, nuanced and comprehensive theory of positioning is needed.
Myosin binding protein C is differentially phosphorylated upon myocardial stunning in canine and rat hearts — Evidence for novel phosphorylation sites

Myocardial stunning is the transient cardiac dysfunction that follows brief episodes of ischemia and reperfusion without associated myocardial necrosis. Currently, there is limited knowledge about its cellular and biochemical mechanisms. In order to better understand the underlying mechanisms of contractile dysfunction associated with the stunning, comprehensive proteomic studies using 2‐D DIGE were performed using a regional stunning model in canine heart. Cardiac myosin binding protein C (cMyBP‐C), a regulatory myofilament protein associated with the thick filament, and nebulette, a thin filament associated protein, were differentially expressed. Phosphoprotein specific staining indicated both protein changes were due to phosphorylation. Subsequent phosphorylation mapping of canine cMyBP‐C using IMAC and MS/MS identified five phosphorylation sites, including three novel sites. In order to further evaluate this finding in a different model, cMyBP‐C phosphorylation was examined in a rat model of global stunning. In the rat model, stunning was associated with increased phosphorylation of cMyBP‐C at a critical calcium/calmodulin‐dependent kinase II site, and the increased phosphorylation was largely inhibited when stunning was prevented by either ischemic preconditioning or reperfusion in the presence of low‐calcium buffer. These data indicate cMyBP‐C phosphorylation plays an important role in myocardial stunning.
PEAS: Private, Efficient and Accurate Web Search

Accounting for the large number of queries sent by users to search engines on a daily basis, the latter are likely to learn and possibly leak sensitive information about individual users. To deal with this issue, several solutions have been proposed to query search engines in a privacy preserving way. A first category of solutions aim to hide users' identities, thus enforcing unlinkability between a query and the identity of its originating user. A second category of approaches aims to obfuscate the content of users' queries, or at generating fake queries in order to blur user profiles, thus enforcing indistinguishability between them. In this paper we propose PEAS, a new protocol for private Web search. PEAS combines a new efficient unlinkability protocol with a new accurate indistinguishability protocol. Experiments conducted using a real dataset of search logs show that compared to state-of-the-art approaches, PEAS decreases by up to 81.9% the number of queries linked to their original requesters. Furthermore, PEAS is accurate as it allows users to retrieve up to 95.3% of the results they would obtain using search engines in an unprotected way.
On the efficiency of Bayesian bandit algorithms from a frequentist point of view

In this contribution, we argue that algorithms derived from the Bayesian modelling of the multiarmed bandit problem are also optimal when evaluated using the frequentist cumulated regret as a measure of performance. We first show that the classical Gittins argument can be applied to convert the finite-horizon Bayesian multiarmed bandit problem into an MDP planning task that is numerically solvable for moderate horizons. The corresponding strategy is shown in simulations to outperform its competitors, including approaches, such as the recently proposed KL-UCB algorithm, that are known to be asymptotically optimal in the sense of reaching the lower bound of Lai and Robbins for the regret. Motivated by this observation, we propose a crude approximation of the optimal Bayesian decision rule in the form of a simple index policy using, for each arm, a suitably chosen quantile of the posterior distribution of the mean. For Bernoulli rewards, this algorithm is shown to be asymptotically optimal and turns out to show interesting connections with several recently proposed refinements of the UCB algorithm. 1 Two points of view on the multiarmed bandit problem In the parametric stochastic multiarmed bandit model, an agent faces K independent arms which depend on unknown parameters θ1, . , θK . The draw of arm j results in a reward that is read from the i.i. d sequence (Yj,t)t∈N with mean μj . The agent sequentially draws the arms and his aim is to find a strategy It, where It is the arm chosen after t rounds, based on previous rewards (Xs = Ys,Is−1)s≤t, that maximizes the expected rewards until time n, Eθ [ ∑n t=1Xt], or equivalently minimizes the cumulated regret :
The role of semantic expectation versus written words stimuli involvement in N400 onset: A patented psychoverbal stimulation interface for EPs and reaction time recordings

The experiments used a patented psycho-verbal stimulation interface to study the origin of cognitive visual N400 evoked potential onset in reading process. The acquisition was performed in Oz, Pz, Cz, Fz leads, on a group of 50 normal persons, in two experiments. First experiment aims to probe the automatic origin of N400 by delivered each 500 words-lists at short asynchronic stimulation 200 ms and long asynchronic stimulation 1000 ms in a letter recognition task. Second experiment proposes to test the role of words expectancy in N400 onset by a letter recognition task at words semantic selected. Grand AVG function was used on each experiment for the average-group recordings at each task and statistic SPSS software based on ANOVA method was used to compare the differences in amplitude of N400. We observed overlapping traces for both acquisitions: at short asynchronic stimulation 200 ms and long asynchronic stimulation 1000 ms. Between the two tracks there is no difference amplitude and N400 wave is present. N400 elicited at unexpected words-list a prove to be a pronounced negativity between 350-450 ms and expected stimuli has produced no N400 effect, but a slight positivity between 350-500.
Advances in the Chromosome-Centric Human Proteome Project: looking to the future

ABSTRACT Introduction: The mission of the Chromosome-Centric Human Proteome Project (C-HPP), is to map and annotate the entire predicted human protein set (~20,000 proteins) encoded by each chromosome. The initial steps of the project are focused on ‘missing proteins (MPs)’, which lacked documented evidence for existence at protein level. In addition to remaining 2,579 MPs, we also target those annotated proteins having unknown functions, uPE1 proteins, alternative splice isoforms and post-translational modifications. We also consider how to investigate various protein functions involved in cis-regulatory phenomena, amplicons lncRNAs and smORFs. Areas covered: We will cover the scope, historic background, progress, challenges and future prospects of C-HPP. This review also addresses the question of how we can best improve the methodological approaches, select the optimal biological samples, and recommend stringent protocols for the identification and characterization of MPs. A new strategy for functional analysis of some of those annotated proteins having unknown function will also be discussed. Expert commentary: If the project moves well by reshaping the original goals, the current working modules and team work in the proposed extended planning period, it is anticipated that a progressively more detailed draft of an accurate chromosome-based proteome map will become available with functional information.
MAXIMUM FILTER VIBRATO SUPPRESSION FOR ONSET DETECTION

We present SuperFlux - a new onset detection algorithm with vi-brato suppression. It is an enhanced version of the universal spectral ﬂux onset detection algorithm, and reduces the number of false positive detections considerably by tracking spectral trajectories with a maximum ﬁlter. Especially for music with heavy use of vibrato (e
