Socialized Language Model Smoothing via Bi-directional Influence Propagation on Social Networks

In recent years, online social networks are among the most popular websites with high PV (Page View) all over the world, as they have renewed the way for information discovery and distribution. Millions of users have registered on these websites and hence generate formidable amount of user-generated contents every day. The social networks become "giants", likely eligible to carry on any research tasks. However, we have pointed out that these giants still suffer from their "Achilles Heel", i.e., extreme sparsity. Compared with the extremely large data over the whole collection, individual posting documents such as microblogs seem to be too sparse to make a difference under various research scenarios, while actually these postings are different. In this paper we propose to tackle the Achilles Heel of social networks by smoothing the language model via influence propagation. To further our previously proposed work to tackle the sparsity issue, we extend the socialized language model smoothing with bi-directional influence learned from propagation. Intuitively, it is insufficient not to distinguish the influence propagated between information source and target without directions. Hence, we formulate a bi-directional socialized factor graph model, which utilizes both the textual correlations between document pairs and the socialized augmentation networks behind the documents, such as user relationships and social interactions. These factors are modeled as attributes and dependencies among documents and their corresponding users, and then are distinguished on the direction level. We propose an effective learning algorithm to learn the proposed factor graph model with directions. Finally we propagate term counts to smooth documents based on the estimated influence. We run experiments on two instinctive datasets of Twitter and Weibo. The results validate the effectiveness of the proposed model. By incorporating direction information into the socialized language model smoothing, our approach obtains improvement over several alternative methods on both intrinsic and extrinsic evaluations measured in terms of perplexity, nDCG and MAP measurements.
Analysis and Implementation of Improved Performance of Triplen Harmonic Injection for Vienna Rectifier

This article is a study on the analysis of harmonics reductions and load voltage control for Vienna Rectifier (VR) with help of the Triplen Harmonic Injection (THJ) and the proportional integral controller (PIC). The sinusoidal PWM is the easiest modulation technique for AC-DC rectifiers to comprehend; however, it is not capable of entirely using the accessible DC bus source voltage. In order to enhance the load voltage regulation and harmonics reductions of the VR, PIC and THJ PWM methods are developed. The performances of the designed PWM methods as well as the PIC are validated at different operating conditions by developing models using MATLAB/Simulink as well as real experimental models. Simulation and experimental results are presented to show the effectiveness of the designed control methods. Keywords, Vienna Rectifier, Triplen Harmonic Injection, Proportional Integral Controller
Masking in Social Network Sites — Translating a Real-World Social Practice to the Online Domain

Abstract Research shows that most social network sites contain serious privacy risks for users. Many of these risks revolve around users´ inability to know exactly who the “audience” is that witnesses their online behaviours. In this article we argue that in the offline world individuals regularly use the strategy of “masking” to hide their visibility when the composition of their audience is unknown. We claim that “masking” should also be facilitated in social network sites to enhance users´ privacy-protection. However, SNSs´ platform design, focused on self-presentation, makes its implementation difficult. Zusammenfassung Die meisten sozialen Netze stellen bedeutende Datenschutzrisiken für die Benutzer dar. Viele dieser Risiken hängen damit zusammen, dass Benutzer nicht genau den “Zuschauerkreis” kennen, welcher ihr Online-Verhalten beobachten kann. In der realen Welt verwenden Menschen die Strategie der “Maskierung” um ihre Anwesenheit zu verstecken, falls der Zuschauerkreis unbekannt ist. Wir behaupten, dass die “Maskierung” auch in sozialen Netzen als Datenschutztechnik dem Benutzer zur Verfügung stehen sollte. Dies ist jedoch schwierig, da Soziale Netze auf Selbstdarstellung ausgerichtet sind.
A PERSONALIZED COURSE GENERATION SYSTEM BASED ON TASK-CENTERED INSTRUCTION STRATEGY

The Course Generation System (CGS) is a system that generates a course accommodate to the teaching material, student status and learning goal. In this paper we present a framework for authoring/course generation system using ontology and an HTN planning technique called PANDA.TUTOR. This system allows the author to prepare the course structure and content, enriched with classification information without need to define the adaptation rules or specify configurations for each student, aiming to keep all the authoring process low in terms of time and effort. The course generation system, which is basically an HTN planning system, introduces a personality based planning approach, in which the course structure and the course content are generated and adapted according to students’ personality and state. The system enriches with different learning scenarios, teaching strategies and learning styles. The student’s personality type taken as a guide to select an appropriate scenario, teaching strategy, and learning style in order to regulate the current emotional and motivational state of student.

Inhibition of the baroreceptor reflex on stimulation in the brain stem defence centre

1. In anaesthetized cats, the pattern of cardiovascular response characteristic of the defence reaction has been elicited by localized electrical stimulation within the appropriate region of the hypothalamus. The baroreceptor reflex response has been elicited by raising the pressure in a blind sac preparation of the carotid sinus or by electrical stimulation of the sinus nerve.

We apply the methodology by modelling in ProMeLa and using SPIN for simulation and verification. We illustrate how the method is applied and some of the insights the developing team gained in its application.
Attention and Executive Function Deficits in Adolescent Sex Offenders

Thirty male adolescent sex offenders and 20 age-matched male adolescents completed an extensive battery of attention and executive function tests. Controls were obtained from adolescents from a socially and economically deprived background, typical of the offending group. The attention battery was based on Mirksy, Anthony, Duncan, Ahearn, and Kellam (1991) and the executive function battery on Kelly (2000a). Successful matching for IQ was not achieved and therefore ANCOVA comparisons were made between the groups, with IQ as the covariate. In attention a highly significant difference was found on the focus-execute factor and a significant difference on the shift factor. In executive function there was a highly significant difference only on the response speed factor. In all cases better abilities were demonstrated by the control group. The importance of thorough neuropsychological investigation in the clinical assessment of this forensic group is supported. The clinical implications of neuropsychological deficits in terms of risk assessment and clinical management are discussed.
Emergence of G9 P[6] Human Rotaviruses in Argentina: Phylogenetic Relationships among G9 Strains

ABSTRACT Because rotavirus diarrhea can be reduced through vaccination and because current vaccine candidates provide protection against only the most common G antigenic types (G1 to G4), detection of uncommon G types is one of the main goals of rotavirus surveillance. After a 2-year nationwide rotavirus surveillance study in Argentina concluded, surveillance was continued and an increase of G9 prevalence in several Argentine cities was detected. During this period G9 strains predominated in the south, and a gradient of decreasing G9 prevalence was observed from south to north (41 to 0%). Sequence analysis of gene 9, encoding the G antigen, showed that Argentine strains cluster with most G9 isolates from other countries, showing less than 2% nucleotide divergence among them, but are distinctive from them in that they present some unique amino acid changes. Our results agree with reports of increased G9 prevalence in other parts of the world, suggesting the need to incorporate G9 into candidate rotavirus vaccines.
GreenMACC: An architecture to green metascheduling with quality of service in private clouds

This paper aims to propose the GreenMACC, an extension of MACC architecture (Metascheduling Architecture To provide QoS in Cloud Computing) aimed at providing QoS in a structure green computing services in a private cloud. To test the new proposed architecture, this paper presents a performance evaluation of policies of the four stages of scheduling with a focus on energy consumption and the average response time. The GreenMACC architecture was consistent in its operation allowing multiple users to run various services on a large scale private cloud and being able to control the energy consumption and quality of services.
Implementation Strategy for a Public Service Based on Cloud Computing at the Government

The present study analyzes policies on cloud computing (CC) in five countries (USA, UK, Japan, Australia, and Singapore) and deduces their implications. It also suggests and analyzes a list of 15 guidelines, 20 check lists, and a service analysis model to implement a public service based on cloud computing (PSBCC). The outline of the necessary procedure for the implementation of a PSBCC is proposed. The analysis model of the service to be implemented is proposed to select the PSBCC that is to be implement according to the promoted policies. The checklist to determine the PSBCC implementation is proposed, which can also be used as data to examine the validity of the implementation. These suggestions provide a systematic method to establish high-quality PSBCC, and the established PSBCC is expected to reduce Information Communication Technology (ICT) operation costs and promote service innovation from the business perspective.
Assessment of endothelial function and blood metabolite status following acute ingestion of a fructose‐containing beverage

Aim: Fructose intake has increased concurrent with sugar intake and this increase has been implicated in contributing to the development of metabolic syndrome risk factors. Recent evidence suggests a role for uric acid (UA) as a potential mediator via suppression of nitric oxide (NO) bioavailability. The aim of this study was to explore this hypothesis by measuring changes in UA concentration and systemic NO bioavailability as well as endothelial function in response to acute ingestion of a glucose‐fructose beverage.
PSD Map Construction Scheme Based on Compressive Sensing in Cognitive Radio Networks

of late, many researchers have been interested in sparse representation of signals and its applications such as Compressive Sensing in Cognitive Radio (CR) networks as a way of overcoming the issue of limited bandwidth. Compressive sensing based wideband spectrum sensing is a novel approach in cognitive radio systems. Also in these systems, using spatial-frequency opportunistic reuse is emerged interestingly by constructing and deploying spatial-frequency Power Spectral Density (PSD) maps. Since the CR sensors are distributed in the region of support, the sensed PSD by each sensor should be transmitted to a master node (base-station) in order to construct the PSD maps in space and frequency domains. When the number of sensors is large, this data transmission which is required for construction of PSD map can be challenging. In this paper, in order to transmit the CR sensors' data to the master node, the compressive sensing based scheme is used. Therefore, the measurements are sampled in a lower sampling rate than of the Nyquist rate. By using the proposed method, an acceptable PSD map for cognitive radio purposes can be achieved by only 30% of full data transmission. Also, simulation results show the robustness of the proposed method against the channel variations in comparison with classical methods. Different solution schemes such as Basis Pursuit, Lasso, Lars and Orthogonal Matching Pursuit are used and the quality performance of them is evaluated by several simulation results over a Rician channel with respect to several different compression and Signal to Noise Ratios. It is also illustrated that the performance of Basis Pursuit and Lasso methods outperform the other compression methods particularly in higher compression rates.
INTERACTIVE CUTTING OF THE SKULL FOR CRANIOFACIAL SURGICAL PLANNING

We present a prototype surgical planning system that simulates cutting and positioning operations on rigid objects such as the human skull, with realistic haptic and visual feedback. Our positioning interface allows users to grab and manipulate objects while sensing the interaction forces between the object being manipulated and other objects in the environment. The cutting interfaces support planar and contour cuts. We present two algorithms that create both types of cuts through rigid objects that are represented by closed triangular meshes. Both algorithms create cuts with predictable accuracies independent of the meshes they operate on, and avoid the introduction of degenerate mesh elements. For contour cuts, the cut region may be closed or open, and whenever possible it is separated from the original object. To deal with discontinuities in the surface meshes of solid objects introduced by such operations, we have implemented an appropriate surface-reconstruction algorithm.
STUDIES ON THE NUTRITION AND PHYSIOLOGY OF PASTEURELLA PESTIS I. A

The chemically defined culture media for Pasteurella pestis which were formulated by Rao (1939, 1940a, b), Berkman (1942), Doudoroff (1943), and Herbert (1949) did not support the growth of any of the 27 strains available in this laboratory. This report describes the.development of a chemically defined medium which was evaluated in terms of the following criteria: yields of viable cells, minimum size of inoculum, suitability for maintamin g virulence on repeated subculture, and as a solid medium.
Ionic accumulation and membrane properties of enriched preparation of neurons and glia from mammalian cerebral cortex

RECENTLY a density gradient method was described for large-scale preparation from mammalian brain of fractions enriched in neurons and glial cells (ROSE, 1967). These fractions displayed glycolytic activity and absorbed oxygen in the presence of glucose at rates approaching those of cortex slices under the same conditions, whilst cells ruptured in a tissue homogenizer absorbed oxygen at only one-third of this rate. The capacity of the enriched fractions to accumulate K+ and histidine, generate resting membrane potentials, and show a respiratory response to 20-fold increases in external K+ concentration have now been examined.
Neonatal alcohol exposure permanently disrupts the circadian properties and photic entrainment of the activity rhythm in adult rats.

BACKGROUND Alcohol exposure during the period of rapid brain development produces structural damage in different brain regions, including the suprachiasmatic nucleus (SCN), that may have permanent neurobehavioral consequences. Thus, this study examined the long-term effects of neonatal alcohol exposure on circadian behavioral activity in adult rats. METHODS Artificially reared Sprague-Dawley rat pups were exposed to alcohol (EtOH; 4.5 g/kg/day) or isocaloric milk formula (gastrostomy control; GC) on postnatal days 4-9. At 2 months of age, rats from the EtOH, GC, and suckle control (SC) groups were housed individually, and properties of the circadian rhythm in wheel-running behavior were continuously analyzed during exposure to a 12-hr light:12-hr dark photoperiod (LD 12:12) or constant darkness (DD). RESULTS Neonatal alcohol exposure had distinctive effects on the rhythmic properties and quantitative parameters of adult wheel-running behavior. EtOH-treated animals were distinguished by unstable and altered entrainment to LD 12:12 such that their daily onsets of activity were highly variable and occurred at earlier times relative to control animals. In DD, circadian regulation of wheel-running behavior was altered by neonatal alcohol exposure such that the free-running period of the activity rhythm was shorter in EtOH-exposed rats than in control animals. Total amount of daily wheel-running activity in EtOH-treated rats was greater than that observed in the SC group. In addition, the circadian activity patterns of EtOH-exposed rats were fragmented such that the duration of the active phase and the number of activity bouts per day were increased. CONCLUSIONS These data indicate that neonatal alcohol exposure produces permanent changes in the circadian regulation of the rat activity rhythm and its entrainment to LD cycles. These long-term alterations in circadian behavior, along with the developmental alcohol-induced changes in SCN endogenous rhythmicity, may have important implications in clinical sleep-wake disturbances observed in neonates, children, and adults exposed to alcohol in utero.
A new intracoronary measurement catheter, MetriCath, compared to intravascular ultrasound and quantitative coronary angiography in a stented porcine coronary model

The purpose of this study was to compare measurements by MetriCath to intravascular ultrasound (IVUS) and quantitative coronary angiography (QCA). The MetriCath system consists of a low‐pressure (200 mm Hg) balloon catheter connected to a pressure transducer and infusion pump linked to a computer that records pressure‐volume curves. Cross‐sectional area of blood vessels is obtained directly from the unrestrained and in‐stent pressure‐volume measurements. We compared stent cross‐sectional area measurements by MetriCath, IVUS, and QCA in a porcine stented coronary artery model. Comparison of area measurements in 14 stents showed no significant differences between the three methods (P = 0.66). On average, values differed 0.37 ± 0.60 mm2 between MetriCath and QCA, 0.13 ± 0.55 mm2 between MetriCath and IVUS, and 0.22 ± 0.80 mm2 between IVUS and QCA. This corresponds to 6.2% ± 10%, 3.0% ± 9.0%, and 3.1% ± 12.9% relative difference from the average of two corresponding measurements. Linear regression analysis showed excellent correlation between measurements (r = 0.99 for all comparisons). The differences in in‐stent area measurements between MetriCath and both QCA and IVUS were small. Considering the ease and rapidity of obtaining MetriCath results, this technique may form an alternative to the others in evaluating stent expansion. Based on these findings, clinical evaluation seems warranted. Cathet Cardiovasc Intervent 2002;57:2–9. © 2002 Wiley‐Liss, Inc.
Intellectual Capital Disclosure in the Annual Report: content Analysis Approach of “Teck” Companies in Bangladesh

This study has opted for an in-depth inquiry into the voluntary intellectual capital (IC) disclosure practices in Bangladesh. Content analysis of the annual reports of 20 listed technology, entertainment, communication and other knowledge (TecK) companies is carried out on the basis of an applicable list of IC-related terms. Extent of voluntary IC disclosures is found almost negligible. Technology based companies (IT and Telecommunication) have a very poor disclosure. However, disclosure of other knowledge based firms is significantly better than other firms in the study. This study also explains how traditional culture and values of a developing country are in conflict with the rational ideas of transparency and adequate disclosure. It suggests the policy makers to make some statutory provisions for IC disclosure in the interest of the stakeholders as well as take initiatives to increase incentive for changing poor traditional disclosure culture.
Exophytic renal masses: angular interface with renal parenchyma for distinguishing benign from malignant lesions at MR imaging.

PURPOSE To retrospectively determine whether benign exophytic renal masses can be distinguished from renal cell carcinoma (RCC) on the basis of angular interface at single-shot fast spin-echo (SE) T2-weighted magnetic resonance (MR) imaging. MATERIALS AND METHODS This retrospective study was compliant with HIPAA and was approved by the institutional review board. Patient informed consent was waived. A total of 162 exophytic (2 cm or greater) renal masses in 152 patients (103 men, 49 women; mean age, 58 years; age range, 23-85 years) were included. Two radiologists independently recorded the mass size and angular interface on single-shot fast SE T2-weighted MR images. Surgical pathologic report and MR follow-up were used as reference standards. Logistic regression analysis was used to examine the usefulness of these variables for differentiating benign masses from RCCs. Diagnostic performance was analyzed by comparing values for area under receiver operating characteristic curve (A(z)). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of angular interface for diagnosing benign masses were calculated. Reader agreement was assessed with kappa-weighted statistics and intraclass correlation coefficients (ICCs). RESULTS Of 162 masses, 65 were benign, and 97 were RCCs. The sensitivity, specificity, PPV, NPV, and A(z) of angular interface for diagnosing benign masses were 78%, 100%, 100%, 87%, and 0.813, respectively. Angular interface (P < .001) was a significant predictor of benign renal mass but mass size (P = .66) was not. There was almost perfect interobserver agreement for mass size (ICC = 0.96) and angular interface (kappa = 0.91). CONCLUSION The presence of an angular interface with the renal parenchyma at single-shot fast SE T2-weighted MR imaging is a strong predictor of benignity in an exophytic renal mass 2 cm or greater in diameter with high specificity and diagnostic accuracy.
