Survey on device-to-device communications: Challenges and design issues

Device-to-Device (D2D) communications has been proposed to cellular networks in order to optimize spectrum efficiency and resources utilization. In D2D-assisted networks, the traditional cellular communication techniques are not applicable but rather need to be redesigned to fulfill new requirements. Therefore, new communication techniques are proposed to take the advantages of the D2D connectivity in the network. In this paper, we describe the concept of D2D communications. Then, we review the main challenges and design issues of D2D-assisted networks. This survey focuses on cooperative communications in D2D-assisted networks and addresses challenges which limit the performance of the cooperative D2D-assisted networks such as relay selection, power consumption and multi-casting. Moreover, design issues and approaches to overcome these limitations are explained.
Testing for the Equality of Integration Orders of Multiple Series

Testing for the equality of integration orders is an important topic in time series analysis because it constitutes an essential step in testing for (fractional) cointegration in the bivariate case. For the multivariate case, there are several versions of cointegration, and the version given in Robinson and Yajima (2002) has received much attention. In this definition, a time series vector is partitioned into several sub-vectors, and the elements in each sub-vector have the same integration order. Furthermore, this time series vector is said to be cointegrated if there exists a cointegration in any of the sub-vectors. Under such a circumstance, testing for the equality of integration orders constitutes an important problem. However, for multivariate fractionally integrated series, most tests focus on stationary and invertible series and become invalid under the presence of cointegration. Hualde (2013) overcomes these difficulties with a residual-based test for a bivariate time series. For the multivariate case, one possible extension of this test involves testing for an array of bivariate series, which becomes computationally challenging as the dimension of the time series increases. In this paper, a one-step residual-based test is proposed to deal with the multivariate case that overcomes the computational issue. Under certain regularity conditions, the test statistic has an asymptotic standard normal distribution under the null hypothesis of equal integration orders and diverges to infinity under the alternative. As reported in a Monte Carlo experiment, the proposed test possesses satisfactory sizes and powers.
BLAC: Revoking Repeatedly Misbehaving Anonymous Users without Relying on TTPs

Several credential systems have been proposed in which users can authenticate to service providers anonymously. Since anonymity can give users the license to misbehave, some variants allow the selective deanonymization (or linking) of misbehaving users upon a complaint to a Trusted Third Party (TTP). The ability of the TTP to revoke a user’s privacy at any time, however, is too strong a punishment for misbehavior. To limit the scope of deanonymization, some systems have been proposed in which users can be deanonymized only if they authenticate “too many times,” such as “double spending” with electronic cash. While useful in some applications, such techniques cannot be generalized to more subjective definitions of misbehavior, for example, using such schemes it is not possible to block anonymous users who “deface too many Web pages” on a Web site. We present BLAC, the first anonymous credential system in which service providers can revoke the credentials of misbehaving users without relying on a TTP . Since revoked users remain anonymous, misbehaviors can be judged subjectively without users fearing arbitrary deanonymization by a TTP . Additionally, our construction supports a d-strikes-out revocation policy, whereby users who have been subjectively judged to have repeatedly misbehaved at least d times are revoked from the system. Thus, for the first time, it is indeed possible to block anonymous users who have “defaced too many Web pages” using our scheme.
Slicing floorplans with boundary constraints

In floorplanning of very large scale integration design, it is useful if users are allowed to specify some placement constraints in the packing. One particular kind of placement constraints is to pack some modules on one of the four sides: on the left, on the right, at the bottom, or at the top of the final floorplan. These are called boundary constraints. In this paper, we enhanced a well-known slicing floorplan algorithm to handle these boundary constraints. Our main contribution is a necessary and sufficient characterization of the Polish expression, a representation of the intermediate solutions in the simulated annealing process, so that we can check these constraints efficiently and can fix the expression in case the constraints are violated. We tested our algorithm on some benchmark data and the performance is good.
An Integrated Spiritual Practice Framework for Use Within Social Work

Social work continues to move towards the incorporation of spirituality within social work theory and practice, yet gaps remain at many levels. The current dearth of theorization of spirituality in social work has created a situation where individual social workers wishing to include spirituality in their practice are forced to rely on their own initiative and inventiveness, with no clear theoretical, practical, or ethical guidelines. This article presents the beginnings of an integrated spiritual practice framework which may help to address some of these concerns. This research scrutinized the proposed Integrated Spiritual Practice Framework (ISPF) through literature survey of three spiritual ideologies (Hinduism, Islam, and Buddhism) using the process of metatriangulation. The study found that each ideological perspective provided evidence and support for the structures and concepts of the ISPF. Through the analysis and theory building process, each ideology contributed greater understanding of components of the ISPF, resulting in a more sophisticated and developed framework for integrating spirituality within social work.
Locally Repairable RapidRAID Systematic Codes — One simple convoluted way to get it all

The need to store humongous volumes of data has regurgitated the study of erasure codes, so that reliable fault-tolerant distributed (for scaling out) data stores can be built while keeping the overheads low. In the context of storage codes, one of the most vigorously researched aspect in the last half a decade or so is their repairability - which looks into mechanisms to rebuild the data at a new storage node, to substitute the loss of information when an existing node fails. Desirable (sometimes mutually conflicting or reinforcing) repairability properties include reduction in the volume of I/O operations, minimize bandwidth usage, fast repairs, reduction in the number of live nodes to be contacted to carry out a repair (repair locality), repairing multiple failures simultaneously, etc.
Gender Classification of Mobile Application Reviews

Demographic information plays an important role in personalized mobile applications. Important attributes of the user such as age and gender that are directly useful for providing personalized services are not typically directly available. The advertising industry in particular requires new and better ways to target specific users with certain attributes. This project is exploring the possibility of predicting the gender of mobile application review authors from their text alone.
Evaluating the social capital accrued in large research networks: The case of the Sustainable Forest Management Network (1995-2009)

This paper examines the social capital that evolved in the Sustainable Forest Management Network (SFMN), one of the Canadian Networks of Centres of Excellence. Our longitudinal study shows a sevenfold increase in the total number of researchers and a high density of relationships among (researchers from) provinces across the country. The results of a social network analysis revealed that 52.6 percent of the network researchers maintained the same number of collaborators while 46.7 percent increased their number of collaborators enormously: the maximum increase in number of collaborators being 6900 percent and the minimum 6 percent. A bibliometric analysis suggested that the number of publications was strongly correlated to measures of social capital. From a science and innovation policy perspective, the finding that more than half of the researchers in the SFMN did not increase their personal networks of collaborators raises important questions. A theoretical model is proposed to examine whether funding agencies should focus on fostering various network structures and evolutions or rely on competition in the distribution of research funds through networks. The proposed model is designed to measure the impact of various network structures on the development of social capital and research output.
Genome-Wide Association Study of Maternal and Inherited Loci for Conotruncal Heart Defects

Conotruncal and related heart defects (CTDs) are a group of serious and relatively common birth defects. Although both maternal and inherited genotypes are thought to play a role in the etiology of CTDs, few specific genetic risk factors have been identified. To determine whether common variants acting through the genotype of the mother (e.g. via an in utero effect) or the case are associated with CTDs, we conducted a genome-wide association study of 750 CTD case-parent triads, with follow-up analyses in 358 independent triads. Log-linear analyses were used to assess the association of CTDs with the genotypes of both the mother and case. No association achieved genomewide significance in either the discovery or combined (discovery+follow-up) samples. However, three loci with p-values suggestive of association (p<10−5) in the discovery sample had p-values <0.05 in the follow-up sample and p-values in the combined data that were lower than in the discovery sample. These included suggestive association with an inherited intergenic variant at 20p12.3 (rs6140038, combined p = 1.0×10−5) and an inherited intronic variant in KCNJ4 at 22q13.1 (rs2267386, combined p = 9.8×10−6), as well as with a maternal variant in SLC22A24 at 11q12.3 (rs11231379, combined p = 4.2×10−6). These observations suggest novel candidate loci for CTDs, including loci that appear to be associated with the risk of CTDs via the maternal genotype, but further studies are needed to confirm these associations.
Impactful Research on Transformational Information Technology: An Opportunity to Inform New Audiences

Information technology has arguably been one of the most important drivers of economic and social value in the last 50 years, enabling transformational change in virtually every aspect of society. Although the Information Systems community is engaged in significant research on IT, the reach of our findings may be limited. In this commentary, our objective is to focus the IS community's attention on the striking transformations in economic and social systems spawned by IT and to encourage more research that offers useful implications for policy. We present examples of transformations occurring in four distinct sectors of the economy and propose policy-relevant questions that need to be addressed. We urge researchers to write papers based on their findings that inform policy makers, managers, and decision makers about the issues that transformational technologies raise. Finally, we suggest a new outlet to publish these essays on the implications of transformational informational technology.
Spiritual Awareness, Personal Perspective on Death, and Psychosocial Distress Among Cancer Patients

This study examined the relationship between transpersonal development and psychosocial distress of cancer patients. The study was based on a theoretical model of transpersonal development conceptualized as a relationship between one's personal perspective on death and one's level of spiritual awareness. A cross-sectional survey design was used to collect data during a single interview. A random sample of 116 men and women with cancer who were being seen in the oncology outpatient department of a regional cancer center participated in the study. Data was collected with the following: a brief questionnaire concerning demographic and oncologic information, the Transpersonal Development Inventory (developed by the first author), and the Death Attitude Profile and the Brief Symptom Inventory, which have established validity and reliability. A significant negative correlation between level of transpersonal development and level of psychosocial distress supported the major hypothesis. Twenty-four percent of the.
Regulation of scavenger receptor CD163 expression in human monocytes and macrophages by pro‐ and antiinflammatory stimuli

CD163, also referred to as M130, a member of the scavenger receptor cysteine‐rich family (SRCR) is exclusively expressed on cells of the monocyte lineage. In freshly isolated monocytes the CD14bight CD16+ monocyte subset revealed the highest expression of CD163 among all monocyte subsets. CD163 mRNA and protein expression is up‐regulated during macrophage colony‐stimulating factor (M‐CSF)‐dependent phagocytic differentiation of human blood monocytes. In contrast, monocytic cells treated with GM‐CSF and interleukin‐4 (IL‐4) for dendritic differentiation down‐regulate this antigen. CD163 expression is also suppressed by proinflammatory mediators like lipopolysaccharide (LPS), interferon‐γ (IFN‐γ), and tumor necrosis factor α, whereas IL‐6 and the antiinflammatory cytokine interleukin‐10 (IL‐10) strongly up‐regulate CD163 mRNA in monocytes and macrophages. The effects of the immunosuppressants dexamethasone, cyclosporin A (CA), and cortisol differ in their capacity to influence CD163 mRNA levels. Our results demonstrate that CD163 expression in monocytes/macrophages is regulated by proinflammatory and antiinflammatory mediators. This expression pattern implies a functional role of CD163 in the antiinflammatory response of monocytes. J. Leukoc. Biol. 67: 97–103; 2000.
The formation of ordered nanoclusters controls cadherin anchoring to actin and cell–cell contact fluidity

Oligomerization of cadherins could provide the stability to ensure tissue cohesion. Cadherins mediate cell–cell adhesion by forming trans-interactions. They form cis-interactions whose role could be essential to stabilize intercellular junctions by shifting cadherin clusters from a fluid to an ordered phase. However, no evidence has been provided so far for cadherin oligomerization in cellulo and for its impact on cell–cell contact stability. Visualizing single cadherins within cell membrane at a nanometric resolution, we show that E-cadherins arrange in ordered clusters, providing the first demonstration of the existence of oligomeric cadherins at cell–cell contacts. Studying the consequences of the disruption of the cis-interface, we show that it is not essential for adherens junction formation. Its disruption, however, increased the mobility of junctional E-cadherin. This destabilization strongly affected E-cadherin anchoring to actin and cell–cell rearrangement during collective cell migration, indicating that the formation of oligomeric clusters controls the anchoring of cadherin to actin and cell–cell contact fluidity.
Language and compiler support for mixin programming

The need to reduce the cost of software development and maintenance has been a constant and overriding concern since the advent of electronic computing. The difficulty, and therefore the expense, in programming large software applications is due to the complex interactions and interdependencies in application code. These interdependencies increase costs by making code hard to understand, hard to change, and hard to reuse. For over a half century, the need to reduce code complexity has been the driving force behind the trend to program at higher levels of abstraction with increased code modularity. This dissertation takes a step towards increasing code modularity by showing that mixin generic types can be used effectively to build applications from reusable software components. First, we address issues of language definition and integration. We show how mixins can be integrated into a modern programming language to support a methodology of incremental software construction. We identify novel language and compiler features that make programming with mixins convenient and efficient. Second, we address issues of implementation and evaluation. We implement a critical subset of mixin language support in a compiler. We then use our compiler to show that mixins increase code reuse compared to current technologies; to show that application development and maintenance can be simplified using mixins; and to show that our novel language features simplify mixin programming. In addition, we discuss language implementation issues and define a new design pattern useful in mixin programming.
Microorganism Response to Stressed Terrestrial Environments: A Raman Spectroscopic Perspective of Extremophilic Life Strategies

Raman spectroscopy is a valuable analytical technique for the identification of biomolecules and minerals in natural samples, which involves little or minimal sample manipulation. In this paper, we evaluate the advantages and disadvantages of this technique applied to the study of extremophiles. Furthermore, we provide a review of the results published, up to the present point in time, of the bio- and geo-strategies adopted by different types of extremophile colonies of microorganisms. We also show the characteristic Raman signatures for the identification of pigments and minerals, which appear in those complex samples.
Frequent p53 mutation in brain (fetal)-type glycogen phosphorylase positive foci adjacent to human ‘de novo’olorectal carcinomas

‘de novo’ carcinogenesis has been advocated besides ‘adenoma carcinoma sequence’ as another dominant pathway leading to colorectal carcinoma. Our recent study has demonstrated that the distribution of brain (fetal)-type glycogen phosphorylase (BGP) positive foci (BGP foci) has a close relationship with the location of ‘de novo’ carcinoma. The aims of the present study are to investigate genetic alteration in the BGP foci and to characterize them in the ‘de novo’ carcinogenesis. 17 colorectal carcinomas without any adenoma component expressing both immunoreactive p53 and BGP protein were selected from 96 resected specimens from our previous study. Further investigations to examine the proliferating cell nuclear antigen (PCNA)-labelling index, and the p53 and the codon 12 of K-ras mutation using the polymerase chain reaction-single strand conformation polymorphism were performed in the BGP foci, BGP negative mucosa and carcinoma. The BGP foci were observed sporadically in the transitional mucosa adjacent to the carcinoma in all cases. The PCNA labelling index in the BGP foci was significantly higher than that in the BGP negative mucosa (P< 0.001). p53 mutations were observed in 8 carcinomas, but no K-ras mutation was detected. Interestingly, although none of the overexpressions of p53 protein was detected immunohistochemically in the BGP positive foci, the p53 gene frequently (41.2% of the BGP foci tested) mutated in spite of no K-ras mutation. The present study demonstrates potentially premalignant foci in the colorectal transitional mucosa with frequent p53 gene mutation. It is suggested that BGP foci are promising candidates for the further investigation of ‘de novo’ colorectal carcinogenesis. © 2001 Cancer Research Campaign http://www.bjcancer. com
El discurso de la RSC en los medios de comunicación social

Corporate social responsibility is gradually taking part of the media due to its practice in companies and institutions. What began twenty years ago, nowadays has become part of the business culture and corporative philosophy in many organizations. This social trend is collected by the media with scepticism, interpreted in some occasions as a technique of image and reputation improvement and not as social commitment. Social communication is responsible for gathering these practices and educating society in this business practice tendency.
Functional roles of social support within the stress and coping process: A theoretical and empirical overview

This article reports four longitudinal field studies and one experimental study designed to shed light on the functional roles of social support within the stress and coping context. First, the enabling hypothesis is examined that assumes a facilitating effect of support on self‐efficacy, which, in turn, promotes coping with the aftermath of cardiac surgery. Second, we discuss the support cultivation hypothesis that regards support as a mediator between self‐efficacy and various outcomes, such as depressive mood, as illustrated by a finding on the experience of macrosocial stress during the East German transition. Third, support is highlighted as a coping resource by specifying provided partner support as a predictor of patients' coping with cancer. It was found that the direct effect of provided support on coping needs to be mediated by received support in order to become effective. Fourth, coping efforts of a target person are found to be predictive of support intentions of a potential provider. The bet.
Context-aware modelling of continuous location-dependent queries in indoor environments

Emerging and continuing advances in ambient systems and localization techniques have brought novel opportunities to develop context-aware navigation services in indoor environments. Diverse kinds of services delivered to the users can be provided by enabling real-time integration of contextual dimensions. In particular, continuous location-dependent queries can be considered as key elements for the development of different categories of context-aware services. However, most work on location-dependent query processing has been mainly oriented towards outdoor environments. This paper introduces a generic architecture for continuous location-dependent and navigation-related queries in indoor environments. A multi-level model of space is designed by taking into account contextual information and the hierarchical layout of an indoor environment. The semantics of a query language for continuous location-dependent queries are introduced, along with some motivating sample queries.
Standards for Augmented Reality: a User Experience perspective

An important aspect of designing and implementing Augmented Reality (AR) applications and services, often disregarded for the sake of simplicity and speed, is the evaluation of such systems, particularly from non-expert users, in real operating conditions. We are strong advocates of the fact that in order to develop successful and highly immersive AR systems, that can be adopted in day-today scenarios, user assessment and feedback is of paramount importance. Consequently, we also feel that an important fragment of future AR Standardisation should focus on User eXperience (UX) aspects, such as the sense of presence, ergonomics, health and safety, overall usability and product identification. Our paper attempts an examination of these aspects and proposes an adaptive theoretical evaluation framework than can be standardised across the span of AR applications.
