Advanced modularity-specialized label propagation algorithm for detecting communities in networks

A modularity-specialized label propagation algorithm (LPAm) for detecting network communities was recently proposed. This promising algorithm offers some desirable qualities. However, LPAm favors community divisions where all communities are similar in total degree and thus it is prone to get stuck in poor local maxima in the modularity space. To escape local maxima, we employ a multistep greedy agglomerative algorithm (MSG) that can merge multiple pairs of communities at a time. Combining LPAm and MSG, we propose an advanced modularity-specialized label propagation algorithm (LPAm+). Experiments show that LPAm+ successfully detects communities with higher modularity values than ever reported in two commonly used real-world networks. Moreover, LPAm+ offers a fair compromise between accuracy and speed.
Modeling with a UML Profile

DEFINITION A Spatial Database Management System (SDBMS) provides storage structures and basic operations for spatial data manipulation, whereas a Geographic Information System (GIS) provides the mechanisms for analysis and visualization of geographic data [16]. Geographic datum is a spatial datum whose basic reference is the earth's surface. Geographic phenomenon applies to any element of the real world having geospatial characteristics. Therefore, a geographic datum describes the spatial characteristic of a geographic phenomenon, in the same way that a descriptive datum describes its qualitative and quantitative characteristics. In this way, Geographic Databases (GeoDB) are collections of geo-referenced spatial data, stored by SDBMS and manipulated by GIS.
A prospective clinical study on titanium implants in the zygomatic arch for prosthetic rehabilitation of the atrophic edentulous maxilla with a follow-up of 6 months to 5 years.

BACKGROUND
Prosthetic rehabilitation with implant-supported prostheses in the atrophic edentulous maxilla often requires a bone augmentation procedure to enable implant placement and integration. However, a rigid anchorage can also be achieved by using so-called zygomatic implants placed in the zygomatic arch in combination with regular implants placed in residual bone.


PURPOSE
The aim of the present study was to report on the clinical outcome of using zygomatic and regular implants for prosthetic rehabilitation of the severely atrophic edentulous maxilla.


MATERIALS AND METHODS
Sixty-nine consecutive patients with severe maxillary atrophy were, during a 5-year period, treated with a total of 69 fixed full-arch prostheses anchored on 435 implants. Of these, 131 were zygomatic implants and 304 were regular implants. Fifty-seven bridges were screw-retained and 12 were cemented. The screw-retained bridges were removed at the examination appointments and each implant was tested for mobility. In addition, the zygomatic implants were subjected to Periotest (Siemens AG, Bensheim, Germany) measurements. The patients had at the time of this report been followed for at least 6 months up to 5 years in loading.


RESULTS
Two regular implants failed during the study period giving a cumulative survival rate of 99.0%. None of the zygomatic implants was removed. All patients received and maintained a fixed full-arch bridge during the study. Periotest measurements of zygomatic implants showed a decreased Periotest values value with time, indicating an increased stability. Three patients presented with sinusitis 14-27 months postoperatively, which could be resolved with antibiotics. Loosening of the zygomatic implant gold screws was recorded in nine patients. Fracture of one gold screw as well as the prosthesis occurred twice in one patient. Fracture of anterior prosthetic teeth was experienced in four patients.


CONCLUSIONS
The results from the present study show that the use of zygomatic and regular implants represents a predictable alternative to bone grafting in the rehabilitation of the atrophic edentulous maxilla.
Evidenced-Based Time-Limited Treatment of Co-occurring Substance-Use Disorders and Civilian-Related Posttraumatic Stress Disorder

Substance use disorders (SUDs) and posttraumatic stress disorder (PTSD) frequently co-occur, and this comorbidity results in a more severe clinical presentation and treatment outcome. Consensus is lacking regarding best practices; however, a number of integrated psychosocial treatments (e.g., Seeking Safety, Substance-Dependence PTSD Therapy, Concurrent Treatment of PTSD and Cocaine Dependence) have shown empirically supported promise in reducing symptoms of both disorders. Very little research has been conducted to date on pharmacological treatments for this dual diagnosis or on assessments. This article reviews the developing literature in this area and discusses future directions for research. [Brief Treatment and Crisis Intervention 6:283–294 (2006)]
A review of hedgehog signaling in cranial bone development

During craniofacial development, the Hedgehog (HH) signaling pathway is essential for mesodermal tissue patterning and differentiation. The HH family consists of three protein ligands: Sonic Hedgehog (SHH), Indian Hedgehog (IHH), and Desert Hedgehog (DHH), of which two are expressed in the craniofacial complex (IHH and SHH). Dysregulations in HH signaling are well documented to result in a wide range of craniofacial abnormalities, including holoprosencephaly (HPE), hypotelorism, and cleft lip/palate. Furthermore, mutations in HH effectors, co-receptors, and ciliary proteins result in skeletal and craniofacial deformities. Cranial suture morphogenesis is a delicate developmental process that requires control of cell commitment, proliferation and differentiation. This review focuses on both what is known and what remains unknown regarding HH signaling in cranial suture morphogenesis and intramembranous ossification. As demonstrated from murine studies, expression of both SHH and IHH is critical to the formation and fusion of the cranial sutures and calvarial ossification. SHH expression has been observed in the cranial suture mesenchyme and its precise function is not fully defined, although some postulate SHH to delay cranial suture fusion. IHH expression is mainly found on the osteogenic fronts of the calvarial bones, and functions to induce cell proliferation and differentiation. Unfortunately, neonatal lethality of IHH deficient mice precludes a detailed examination of their postnatal calvarial phenotype. In summary, a number of basic questions are yet to be answered regarding domains of expression, developmental role, and functional overlap of HH morphogens in the calvaria. Nevertheless, SHH and IHH ligands are integral to cranial suture development and regulation of calvarial ossification. When HH signaling goes awry, the resultant suite of morphologic abnormalities highlights the important roles of HH signaling in cranial development.
Identification of Lps2 as a key transducer of MyD88-independent TIR signalling

In humans, ten Toll-like receptor (TLR) paralogues sense molecular components of microbes, initiating the production of cytokine mediators that create the inflammatory response. Using N-ethyl-N-nitrosourea, we induced a germline mutation called Lps2, which abolishes cytokine responses to double-stranded RNA and severely impairs responses to the endotoxin lipopolysaccharide (LPS), indicating that TLR3 and TLR4 might share a specific, proximal transducer. Here we identify the Lps2 mutation: a distal frameshift error in a Toll/interleukin-1 receptor/resistance (TIR) adaptor protein known as Trif or Ticam-1. TrifLps2 homozygotes are markedly resistant to the toxic effects of LPS, and are hypersusceptible to mouse cytomegalovirus, failing to produce type I interferons when infected. Compound homozygosity for mutations at Trif and MyD88 (a cytoplasmic TIR-domain-containing adaptor protein) loci ablates all responses to LPS, indicating that only two signalling pathways emanate from the LPS receptor. However, a Trif-independent cell population is detectable when TrifLps2 mutant macrophages are stimulated with LPS. This reveals that an alternative MyD88-dependent ‘adaptor X’ pathway is present in some, but not all, macrophages, and implies afferent immune specialization.
Polling systems and multitype branching processes

The joint queue length process in polling systems with and without switchover times is studied. If the service discipline in each queue satisfies a certain property it is shown that the joint queue length process at polling instants of a fixed queue is a multitype branching process (MTBP) with immigration. In the case of polling models with switchover times, it turns out that we are dealing with an MTBP with immigration in each state, whereas in the case of polling models without switchover times we are dealing with an MTBP with immigration in state zero. The theory of MTBPs leads to expressions for the generating function of the joint queue length process at polling instants. Sufficient conditions for ergodicity and moment calculations are also given.
Personality, attitudes, and intentions: Predicting initial adoption of information security behavior

Investigations of computer user behavior become especially important when behaviors like security software adoption affect organizational information resource security, but adoption antecedents remain elusive. Technology adoption studies typically predict behavioral outcomes by investigating the relationship between attitudes and intentions, though intention may not be the best predictor of actual behavior. Personality constructs have recently been found to explain evenmore variance in behavior, thus providing insights into user behavior. This research incorporates conscientiousness and agreeableness into a conceptual model of security software use. Attitudinal constructs perceived ease of use and perceived usefulness were linked with behavioral intent, while the relationship between intent and actual use was found to be moderated by conscientiousness and agreeableness. The results that the moderating effect of personality greatly increases the amount of variance explained in actual use. © 2015 Elsevier Ltd. All rights reserved.
Towards scalable streaming to SAGE2 video walls

Video walls are useful to display large visualizations. The SAGE2 web-based system allows easy programming of scalable visualization applications. However, it is not easy to stream high resolution video to SAGE2 powered video walls. We proposed several methods of high resolution video streaming to LCD walls, evaluated their performance and discuss their scalability and properties.
Accurate mobile robot localization in indoor environments using bluetooth

In this paper, we describe an accurate method for localization of a mobile robot using bluetooth. We introduce novel approaches for obtaining distance estimates and trilateration that overcome the hitherto known limitations of using bluetooth for localization. Our approach is reliable and has the potential of being scaled to multi-agent scenarios. The proposed approach was tested on a mobile robot, and we present the experimental results. The error obtained was 0.427 ± 0.229 m, which proves the accuracy of our method.
Cell phone banking: predictors of adoption in South Africa - an exploratory study

Cell phone usage has grown phenomenally in Africa, and particularly in South Africa where initial growth forecasts have been greatly exceeded. This technology therefore provides opportunities for services such as banking to reach critical mass. All major retail banks in South Africa provide cell phone banking, but very few customers actually use it. This study examines the factors that influence the adoption of cell phone banking in South Africa, as a means of understanding how to possibly increase the rate of adoption. A framework developed in Singapore identifying factors influencing the adoption of Internet banking was used as a basis, and amended to assess cell phone banking. Factors identified as influences included relative advantage, trialability, and consumer banking needs, with perceived risk having a major negative influence. r 2003 Elsevier Ltd.

HANDSET ANTENNA DESIGN: PRACTICE AND THEORY

Abstract—In this paper, an attempt is made to present a theory for the design of handset antennas, which results from the long experience that the authors have in the field of handset antenna design. The proposed theory is based on the well-known skin effect and constructs the antenna using a thin wire model that represent the backbone of the final antenna. The analytical solution for the thin wire model is first obtained, and the main properties (such as the return loss and the radiation properties) of the antenna can then be studied using this analytical solution. Once the antenna backbone is constructed, other elements, such as stubs, patches, etc., can be added to optimize the match at the desired frequency bands. A number of numerical and analytical examples are provided throughout the paper to validate the theory. Different antenna types, such as wire antennas and planar antennas, are tested and designed using the thin wire model. The correspondence between the analytical results and those from the numerical simulations using full-wave solvers agree very well in all examples. The authors also present in this paper a novel design of three small antennas for handset applications, which are based on the simple wire monopole, but in a three-dimensional form. The proposed three-dimensional monopole antennas have multi-band and broadband properties that cover most frequency bands being used for the handset device. The antennas feature remarkable properties while occupying a significantly small space, which makes them strong candidates for handset applications and for the future multi-antenna applications too.

New measurement scales for evaluating perceptions of the technology-mediated customer service experience

Service organizations are increasingly utilizing advanced information and communication technologies, such as the Internet, in hopes of improving the efficiency, cost-effectiveness, and/or quality of their customer-facing operations. More of the contact a customer has with the firm is likely to be with the back-office and, therefore, mediated by technology. While previous operations management research has been important for its contributions to our understanding of customer contact in face-to-facesettings, considerably less work has been done to improve our understanding of customer contact in what we refer to as technology-mediated settings (e.g., via telephone, instant messaging (IM), or email). This paper builds upon the service operations management (SOM) literature on customer contact by theoretically defining and empirically developing new multi-item measurement scales specifically designed for assessing tech ology-mediated customer contact. Seminal works on customer contact theory and its empirical measurement are employed to provide a foundation for extending these concepts to technology-mediated contexts. We also draw upon other important frameworks, including the Service Profit Chain, the Theory of Planned Behavior, and the concept of media/information richness, in order to identify and define our constructs. We follow a rigorous empirical scale development process to create parsimonious sets of survey items that exhibit satisfactory levels of reliability and validity to be useful in advancing SOM empirical research in the emerging Internet-enabled back-office. © 2004 Elsevier B.V.

A preliminary study of emotional intelligence , empathy and exam performance in first year medical students I

A group of 156 first year medical students completed measures of emotional intelligence (EI) and physician empathy, and a scale assessing their feelings about a communications skills course component. Females scored significantly higher than males on EI. Exam performance in the autumn term on a course component (Health and Society) covering general issues in medicine was positively and significantly related to EI score but there was no association between EI and exam performance later in the year. High EI students reported more positive feelings about the communication skills exercise. Females scored higher than males on the Health and Society component in autumn, spring and summer exams. Structural equation modelling showed direct effects of gender and EI on autumn term exam performance, but no direct effects other than previous exam performance on spring and summer term performance. EI also partially mediated the effect of gender on autumn term exam performance. These findings provide limited evidence for a link between EI and academic performance for this student group. More extensive work on associations between EI, academic success and adjustment throughout medical training would clearly be of interest. 2005 Elsevier Ltd.

Phase field modeling of heterogeneous microcrystalline ceramics

Abstract Diffuse interface models and simulations capture deformation and failure of polycrystalline ceramics with multiple phases. Two heterogeneous ceramic solids are investigated. The first consists of a boron carbide matrix phase embedded with titanium diboride grains. Boron carbide may undergo cleavage fracture, twinning, and amorphization under sufficient mechanical loading. Titanium diboride demonstrates cleavage fracture and limited plastic slip. The second ceramic composite consists of diamond crystals with a smaller fraction of silicon carbide grains, where the latter may encapsulate the former in a micro- or nano-crystalline matrix and/or may be interspersed as larger micro-crystals among the diamond grains. Diamond may undergo cleavage fracture while the cubic phase of silicon carbide may fracture and twin. A general constitutive framework suitable for representing behaviors of all phases of each material system is reported. This phase field framework is implemented in three-dimensional (3D) finite element (FE) simulations of polycrystalline aggregates under compressive loading. Numerical results demonstrate effects of grain and phase morphology and activation or suppression of slip or twinning mechanisms on the overall strength and ductility of each material system. Efforts to inhibit localization and cleavage in boron carbide crystals, including addition of titanium diboride, promote increases in strength of the first composite, though residual stresses may be necessary to realize toughness improvements observed experimentally. In the second composite, layers of softer silicon carbide nanocrystals along grain boundaries (GBs) improve overall strength and ductility relative to addition of larger bulk silicon carbide grains.
Sum-product networks: A new deep architecture

The key limiting factor in graphical model inference and learning is the complexity of the partition function. We thus ask the question: what are the most general conditions under which the partition function is tractable? The answer leads to a new kind of deep architecture, which we call sum-product networks (SPNs) and will present in this abstract.
The Impact of Language Anxiety and Language Proficiency on WTC in EFL Context

Spontaneous and sustained use of the L2 inside and outside the classroom varies according to a number of linguistic, communicative, social, and psychological factors. Authentic communication in L2 as a result of the complex interrelated system of variables occurs in terms of utilizing L2 for a variety of communicative acts, such as speaking up in class or reading a newspaper, and changes accordingly over time and across situations. By helping the students to decrease language anxiety and increase a willingness to use the L2 inside and outside the classroom, we direct the focus of language teaching away from merely linguistic and structural competence to authentic communication. Willingness to communicate (WTC) model integrates these variables to predict L2 communication, and a few number of studies have tested the model with EFL students. To this end, the current study is an attempt to shed light on the examination of Iranian EFL university students’ WTC and its interaction with their language anxiety and language proficiency. Forty nine university students participated in this study, took TOEFL first and then filled out two questionnaires of WTC, MacIntyre, Baker, Clement, and Conrod (2001) and language anxiety, Horwitz, Horwitz, and Cope (1986). For data analysis, Repeated Measures ANOVA and Spearman correlation were run and the results have revealed that Iranian university students’ WTC is directly related to their language proficiency but surprisingly higher proficient learners showed to be less communicative than lower proficient ones outside the classroom and this proves the state-like nature of WTC in the present sample. Moreover, the interaction between WTC and anxiety did not turn out to be significant. This shows that anxiety did not affect the learners’ participation in communication (WTC). Finally, anxiety and language proficiency are negatively correlated, so the association between language learning experience and L2 anxiety has been confirmed in the results of this study. Therefore, linguistic variables appear to be more predictive of WTC for Iranians, and language instructors should work on their students' English proficiency.
AFQ056 treatment of levodopa-induced dyskinesias: results of 2 randomized controlled trials.

Study objectives were to assess the efficacy, safety, and tolerability of AFQ056 in Parkinson's disease patients with levodopa-induced dyskinesia. Two randomized, double-blind, placebo-controlled, parallel-group, in-patient studies for Parkinson's disease patients with moderate to severe levodopa-induced dyskinesia (study 1) and severe levodopa-induced dyskinesia (study 2) on stable dopaminergic therapy were performed. Patients received 25-150 mg AFQ056 or placebo twice daily for 16 days (both studies). Study 2 included a 4-day down-titration. Primary outcomes were the Lang-Fahn Activities of Daily Living Dyskinesia Scale (study 1), the modified Abnormal Involuntary Movement Scale (study 2), and the Unified Parkinson's Disease Rating Scale-part III (both studies). Secondary outcomes included the Unified Parkinson's Disease Rating Scale-part IV items 32-33. The primary analysis was change from baseline to day 16 on all outcomes. Treatment differences were assessed. Fifteen patients were randomized to AFQ056 and 16 to placebo in study 1; 14 patients were randomized to each group in study 2. AFQ056-treated patients showed significant improvements in dyskinesias on day 16 versus placebo (eg, Lang-Fahn Activities of Daily Living Dyskinesia Scale, P = .021 [study 1]; modified Abnormal Involuntary Movement Scale, P = .032 [study 2]). No significant changes were seen from baseline on day 16 on the Unified Parkinson's Disease Rating Scale-part III in either study. Adverse events were reported in both studies, including dizziness. Serious adverse events (most commonly worsening of dyskinesias, apparently associated with stopping treatment) were reported by 4 AFQ056-treated patients in study 1, and 3 patients (2 AFQ056-treated patient and 1 in the placebo group) in study 2. AFQ056 showed a clinically relevant and significant antidyskinetic effect without changing the antiparkinsonian effects of dopaminergic therapy. © 2011 Movement Disorder Society.
