Cubature belief propagation for self-localization of wireless networks

Self-localization capability is a key enabler for a diverse set of important wireless applications. This paper presents a low-complexity belief propagation (BP) algorithm, named cubature belief propagation (CBP), for self-localization of wireless networks. The core of the proposed CBP algorithm is a third-degree spherical-radical cubature rule, which makes it possible to numerically compute the nonlinear multivariate moment integrals encountered in BP algorithm. CBP is fully distributed over an unstructured networks and does not require a fusion center, thus suits for an-hoc deployment. Moreover, since the adoption of conventional message passing mechanism, CBP can estimate node locations and represent location uncertainties simultaneously, and thus can be robust to outlier measurement errors. Simulation results show that, for a decentralized, cooperative, dynamic self-localization problem in wireless networks, CBP can outperform nonparametric/particle-based BP in lowing computation and communication overloads.
Changes in Soil Biochemical Properties in a Cedar Plantation Invaded by Moso Bamboo

Moso bamboo (Phyllostachys edulis) is one of the widely growing bamboo species in Asia. Because of its fast growth and aggressive rhizomes, it is reported to invade other forests and reduce the biodiversity of forest ecosystems. To determine the changes in soil nutrient conditions due to moso bamboo invasion, this research measured the difference in soil labile carbon (C) and nitrogen (N) contents in a Japanese cedar (Cryptomeria japonica) forest invaded by moso bamboo in central Taiwan. The content of soluble organic C (SbOC), measured by both KCl and hot-water extraction methods, was lower in bamboo than cedar soils. This observation agreed with the finding that the more easily decomposed SbOC could be lost with bamboo invasion. In addition, both SbOCKCl and SbOCHW contents were positively correlated with microbial biomass C content, so the decreased labile organic C content in bamboo soils may reduce microbial biomass production. Principal component analysis revealed soil organic C content (total organic C, SbOC and acid-hydrolysable C) as the most important soil parameter affected by the bamboo invasion, followed by microbial biomass N and NO3− contents in soils. The soil quality index model also agreed with the degraded soil quality with bamboo invasion. In conclusion, the invasion of moso bamboo reduced the C and N pools in bamboo soil and degraded the overall soil quality.
A Multi-criteria Decision Making ApproachIn Feature Selection For EnhancingText Categorization

This paper considers the problem of feature selection in text categorization. Previous works in feature selection often used a filter model in which features, after ranked by a measure, are selected based on a given threshold. In this paper, we present a novel approach to feature selection based on multi-criteria decision making of each feature. Instead of only one criterion, multi-criteria of a feature are used; and a procedure based on each threshold of the criterion is proposed. This framework seems to be suitable for text data and can be applied to feature selection in text categorization. Experimental results on Reuters-21578 benchmark data show that our approach has a promising scheme and enhances the performance of a text categorization system.
Modified matched signal transform for parameter estimation of spread spectrum stretch signal

The spread spectrum stretch (S-cubed) is a kind of hybrid signal which has the advantages of the expansion and wide instantaneous bandwidth, proved to be the potential option for low probability of intercept (LPI) radar and stealth communications. In this paper, the S-cubed model that superimposes a short, cyclically repeated, discrete phase code on linear frequency modulation (LFM) is presented. In order to extract the signal features, we formulate modified matched signal transform (MMST) and then propose a novel approach to estimate the parameters of S-cubed in MMST domain. Furthermore, the numerical simulation and parameter estimation robustness are also studied. The simulation results show that when signal to noise ratio (SNR) is 7dB, the probability of correct decision (PCD) of the chirp rate has reached 90%. Key-Words: spread spectrum stretch (S-cubed); modified matched signal transform (MMST); parameter estimation.
A survey on energy efficient intrusion detection in wireless sensor networks

Wireless sensor networks (WSNs) have emerged as an important research paradigm since the last decade, thereby motivating researches to take up new theoretical and practical challenges. WSNs need to be provided with efficient security features generally due to their deployment in inaccessible terrain and also communication being in the wireless domain. Therefore the question of providing security to such networks arises but the major constraints are the limited resources present in the sensor nodes. Prior importance is given to the energy parameter as it is the most vital component of the sensor nodes. So the objective of any intrusion detection framework would be to design robust mechanisms capable of handling attacks in energy efficient manner. Intrusion detection is used in WSNs because of their ability to detect unknown attacks and finding means to thwart them for preserving energy. Therefore energy efficient intrusion detection has become a significant research area for researchers. Keeping this in mind, we survey the major topics of energy efficient intrusion detection in WSNs. The survey work presents topics such as the fundamentals of intrusion detection techniques, as well as the various energy saving mechanisms used in different architectural models. The earlier achievements in energy efficient intrusion detection in WSNs are also summarized and existing problems are discussed. We also give an insight into the possible directions for future work in intrusion detection by highlighting open research areas.
The Effect of Working Capital Management on Share Returns of Companies Listed in the Nairobi Securities Exchange

This study investigated the relationship between working capital management and share returns of the 64 companies listed on the Nairobi stock exchange for the period 2010 to 2014. A census methodology was used to select the companies for study. Secondary data was collected for share prices from the NSE handbook while working capital data was obtained from the audited financial statements of the listed companies and data was analyzed using SPSS. The study found a negative but insignificant relationship between average collection period and share returns while there was a positive but insignificant relationship between average payment period and share returns, and cash conversion cycle and share returns. The study recommends that even though there was no significant relationship between working capital and share returns, managers should pay attention to working capital performance as deterioration of performance on working capital could result in significant effect on share returns

Mixing time of the card-cyclic-to-random shuffle

The Card-Cyclic-to-Random shuffle on n cards is defined as follows: at time t remove the card with label t mod n and randomly reinsert it back into the deck. Pinsky [9] introduced this shuffle and asked how many steps are needed to mix the deck. He showed n steps do not suffice. Here we show that the mixing time is on the order of Θ(n log n).
Occupational Licensing and Accountant Quality: Evidence from the 150-Hour Rule

I use the staggered state-level adoption of the 150-hour Rule (the Rule) as a natural experiment along with the career histories of professional accountants’ from LinkedIn to examine the effects of mandatory occupational licensure on the individual quality of Certified Public Accountants (CPAs). Using a difference-in-difference and synthetic control research design, I document that the Rule marginally increases CPA exam pass rates and reduced the candidate supply, leading to an overall decline in the number of successful candidates. My analysis of LinkedIn data shows that individuals subject to the Rule are more likely to be employed at a Big 4 public accounting firm and specialize in taxation. However, Rule individuals have the same likelihood of promotion, the same duration until promotion, and exit public accounting at faster rates than their non-Rule counterparts. These findings suggest that restrictive licensing laws reduced the supply of new CPAs while failing to effectively increase the quality of CPAs as measured by their labor market outcomes.
Differentiation-Induced Radioresistance in Muscle Cells

ABSTRACT DNA damage induces cell cycle arrest and DNA repair or apoptosis in proliferating cells. Terminally differentiated cells are permanently withdrawn from the cell cycle and partly resistant to apoptosis. To investigate the effects of genotoxic agents in postmitotic cells, we compared DNA damage-activated responses in mouse and human proliferating myoblasts and their differentiated counterparts, the myotubes. DNA double-strand breaks caused by ionizing radiation (IR) induced rapid activating autophosphorylation of ataxia-teleangiectasia-mutated (ATM), phosphorylation of histone H2AX, recruitment of repair-associated proteins MRE11 and Nbs1, and activation of Chk2 in both myoblasts and myotubes. However, IR-activated, ATM-mediated phosphorylation of p53 at serine 15 (human) or 18 (mouse) [Ser15(h)/18(m)], and apoptosis occurred in myoblasts but was impaired in myotubes. This phosphorylation could be enforced in myotubes by the anthracycline derivative doxorubicin, leading to selective activation of proapoptotic genes. Unexpectedly, the abundance of autophosphorylated ATM was indistinguishable after exposure of myotubes to IR (10 Gy) or doxorubicin (1 μM/24 h) despite efficient phosphorylation of p53 Ser15(h)/18(m), and apoptosis occurred only in response to doxorubicin. These results suggest that radioresistance in myotubes might reflect a differentiation-associated, pathway-selective blockade of DNA damage signaling downstream of ATM. This mechanism appears to preserve IR-induced activation of the ATM-H2AX-MRE11/Rad50/Nbs1 lesion processing and repair pathway yet restrain ATM-p53-mediated apoptosis, thereby contributing to life-long maintenance of differentiated muscle tissues.
Perceptual differences of enterprise resource planning systems between management and operational end-users

This article seeks to explore the perceptions of two different user groups – management and operational end-users – on enterprise resource planning (ERP) system product performance and post-implementation impact of usage on them. One hundred and sixty-seven management and operational end-users from 15 manufacturing firms operating in Sri Lanka responded. Over 88% of the respondents came from firms that employed more than 500 employees; 68% responded that more than 200 employees are using ERP in their firms; and 70% responded that ERP is in use for more than 3 years in their firms. Significant differences have not been found between the two groups in their perceptions towards ERP system product performance. However, problem-solving support, authority and decision rights and overall performance improvement have been identified as important post-implementation outcomes of ERP usage that discriminate between management and operational end-users.
SPACE-TIME ANALYSIS OF CRIME PATTERNS IN CENTRAL LONDON

Crime continues to cast a shadow over citizen well-being in big cities today, while also imposing huge economic and social costs. Timely understanding of how criminality emerges and how crime patterns evolve is crucial to anticipating crime, dealing with it when it occurs and developing public confidence in the police service. Every day, about 10,000 crime incidents are reported by citizens, recorded and geo-referenced in the London Metropolitan Police Service Computer Aided Dispatch (CAD) database. The unique nature of this dataset allows the patterns to be explored at particularly fine temporal granularity and at multiple spatial resolutions. This study provides a framework for the exploratory spatio-temporal analysis of crime patterns that combines visual inquiry tools (interactive animations, space-time cubes and map matrices) with cluster analysis (spatial-temporal scan statistics and the self-organizing map). This framework is tested on the CAD dataset for the London Borough of Camden in March 2010. Patterns of crime through space and time are discovered and the clustering methods were evaluated on their ability to facilitate the discovery and interpretation of these patterns.
Trends in research in two general psychiatric journals in 1969-1990: research on research.

OBJECTIVE The authors describe the characteristics of psychiatric research over the past two decades as captured in the articles published by two general psychiatric journals. METHOD A total of 1,236 articles were drawn from The American Journal of Psychiatry and Archives of General Psychiatry for October through September 1969-1970, 1979-1980, and 1989-1990. Articles were assigned to one of five categories. Research articles were then further categorized as to methodological approach and field of research as well as specific topic areas. Funding sources listed for each research article were also indexed. RESULTS Over time and in both journals, the percentage and number of research articles have risen, with a concomitant reduction in case reports, opinion papers, and "other" articles. Categories of research design were fairly consistent across time and in both journals. Percentages of articles on specific fields and topics indicated an increasing emphasis on biological studies, especially those in clinical psychobiology, as well as a sharp move away from general categories to a more disorder-specific orientation. Reporting of funding sources has substantially increased. CONCLUSIONS The large proportion of research articles published in these two important general psychiatric journals reflects editorial policies, changing audience expectations, and the availability of new research tools. Systematic analysis of trends in psychiatric research and other forms of research on research can be useful approaches to assessing the growth and utilization of knowledge in the field, to planning how to most effectively use limited research resources, and to increasing public support for research.
Self-Recognition of Vehicle Position Using UHF Passive RFID Tags

This paper proposes a method that enables self-recognition of a mobile vehicle's current position by utilizing ultrahigh frequency (UHF) passive radio-frequency identification (RFID) tags. The proposed method can be used in real industry environments such as complex storage warehouses where many different goods are dispersed throughout a wide area. In particular, the proposed method makes use of two UHF RFID readers with identical emission configuration attached to a vehicle to identify a reference RFID tag. By utilizing the received signal strength indicator obtained by the readers from the reference RFID tag, the precise position of the moving vehicle can be obtained. The experiments prove the effectiveness of the proposed method in accurately estimating the vehicle position.
International Journal of Advanced Research in Computer Science and Software Engineering Cloud Data Protection for Secure and Dependable Storage Services

: Cloud Computing has become a scalable services consumption and delivery platform in the field of Services Computing. The technical foundations of Cloud Computing include Service-Oriented Architecture (SOA) and Virtualizations of hardware and software. The goal of Cloud Computing is to share resources among the cloud service consumers, cloud partners, and cloud vendors in the cloud value chain. The resource sharing at various levels results in various cloud offerings such as infrastructure cloud (e.g., hardware, IT infrastructure management), software cloud (e.g. SaaS focusing on middleware as a service, or traditional CRM as a service), application cloud (e.g., Application as a Service, UML modeling tools as a service, social network as a service), and business cloud (e.g., business process as a service).
Isolation and characterization of 15 polymorphic microsatellites in the Plethodontid salamander Ensatina eschscholtzii

We developed 15 new polymorphic microsatellites for the plethodontid salamander Ensatina eschscholtzii. Loci were isolated from a genomic library from Ensatina eschscholtzii xanthoptica enriched for (AAAG)n repetitive elements. The number of alleles per locus ranged from 4 to 20 (mean 9) in the sampled population. Observed heterozygosity ranged from 0.37 to 1. None of the loci deviated from Hardy–Weinberg equilibrium or showed significant linkage disequilibrium after a Bonferroni correction for multiple comparisons. All loci amplified in the six other subspecies of the Ensatina eschscholtzii complex. These new markers will prove useful in measuring gene flow and population structure as well as patterns of mating and sperm use in Ensatina.
A Staged Primal-Dual Algorithm for Perfect b-Matching with Edge Capacities

We describe an algorithm for finding a minimum cost perfect b-matching in a weighted undirected graph G=(V,E) , with arbitrary edge capacities. The algorithm is based on a staged approach that sequentially applies increasingly more expensive steps until a solution is found. The most significant step involves a primal-dual tree growth procedure that selectively activates and deactivates facet inducing blossom constraints. The algorithm progressively eliminates half-integral values from the primal solution without creating any new fractional values. We introduce the concept of frozen supervertices to address previously unknown complications that arise due to the presence of non-unit capacity edges. We discuss the relationship of the algorithm to previously published cutting plane methods. The algorithm is guaranteed to terminate in O(| V | 2 | E |) steps, although computational results suggest that much less effort is typically required. Computational results show the algorithm to be effective on problems derived from TSPLIB ranging in size from 532 to 3795 vertices for various b values.

Digital Identity in Mobile Products for Digital Innovation

Mobile computing growth has led to a world connecting people, devices, organisations and appliances. This world of ubiquitous computing is served through multiple digital products and services, which provide value to the user. The user is the central player in this digital landscape and the importance of identifying and understanding the user is significant to the creators of digital products and services, or digital innovation. The purpose of this paper is to explore the relationship between digital identity and digital innovation in the context of mobile computing. Exploring this relationship will help further the understanding of whether the presence of digital identity has a positive influence on digital innovation. The exploratory study was conducted using qualitative and quantitative strategies within an inductive approach in order to understand the concepts of digital identity and digital innovation. The Holmström-Nylen (2015) Framework was amended to measure the presence of digital innovation in the product or service and also to classify the relationship between digital identity and digital innovation. The results identified a series of themes and causalities between the implementation of digital identity and mobile computing for digital product or service. The results also suggested a possible relationship between digital innovation and digital identity, depending on the surrounding organisational factors, however there was not enough conclusive evidence of an enabling role between digital identity and digital product or service innovation.
Relationship between Entrepreneurial Orientation, Firm Resources, SME Branding and Firm's Performance: Is Innovation the Missing Link?

Innovation is regarded as an engine for driving economic growth. Innovation is considered equally important for the large enterprises as well as the Small and Medium Enterprises (SMEs). Role of innovation becomes of even greater importance in the context of the business environment of developing countries such as Pakistan, where most of the SMEs do not embrace rigorous innovation and at the same time there is lack of sufficient external support to encourage innovation. It has been discussed that despite of healthy economic contribution to Pakistan’s Economy, SMEs are facing a low growth trap. Innovation can come up as a potential solution specifically for Pakistani SMEs and generally for SMEs in developing countries in other parts of the world. This paper reviews the literature in a thorough manner in a bid to build a novel conceptual framework proposing that innovation has causal linkages with entrepreneurial orientation, firm resources, branding and firm performance. On the basis of literature review, four thoughtful research propositions have been presented in this paper. The proposed framework can lead to very useful insights as it proposes that branding may lead to innovation as opposed to generally believed concept of innovation leading to branding. This paper is built on the underpinning theories like Resource Based View, Dynamic Capabilities Perspective, and Theory of Economic Development. This paper also provides useful implications for the entrepreneurs as well as external institutions responsible for ensuring higher extent of innovation in SMEs in Pakistan.
Prospective study of early neonatal screening for phenylketonuria.

Identification of phenylketonuria (PKU) in the newborn by routine screening depends on the presence of an increased concentration of phenylalanine in the blood when the specimen is obtained. In infants with PKU, phenylalanine is not substantially increased at birth.1 It does, however, increase postnatally as a consequence of the infant's inability to metabolize the phenylalanine that is ingested or liberated from the breakdown of endogenous protein. In the United States, the initial blood specimen for PKU screening is obtained near the time of discharge from the nursery, which is usually on the third day of life. Because of the current .
