Scalable and Flexible Access Control with Secure Data Auditing in Cloud

Cloud computing, which enables on demand network access to shared pool of resources is the latest trend in today’s IT industry. Among different services provided by cloud, cloud storage service allows the data owners to store and share their data through cloud and thus become free from the burden of storage management. But, since the owners lose physical control over their outsourced data, it arises many privacy and security concerns. A number of attribute based encryption schemes are proposed for providing confidentiality and access control to cloud data storage where the standard encryption schemes face difficulties. Among them, Hierarchical Attribute Set Based Encryption (HASBE) provides scalable, flexible and fine grained access control as well as easy user revocation. It is an extended form of Attribute Set Based Encryption (ASBE) with a hierarchical structure of users. But from the view of integrity and availability, HASBE is not sufficient to provide the data owner with the ability to perform checking against missing or corruption of their outsourced data. So, this paper extends HASBE with privacy preserving public auditing concept which additionally allows owners to securely ensure the integrity of their data in the cloud. We are using homomorphic linear authenticator with random masking technique for this purpose. In this paper, the system under consideration applies to Personal Health Record domain. Keywords—Cloud Computing, Access control, Personal Health Record, Homomorphic Linear Authenticator, Random Masking.
Anti-infliximab and anti-adalimumab antibodies in relation to response to adalimumab in infliximab switchers and anti-tumour necrosis factor naive patients: a cohort study

Objective To investigate how antibodies against anti-tumour necrosis factor (anti-TNF) agents influence response after switching from infliximab to adalimumab in rheumatoid arthritis (RA). Methods This cohort study consisted of 235 patients with RA, all treated with adalimumab. At baseline 52 patients (22%) had been previously treated with infliximab (‘switchers’), and 183 (78%) were anti-TNF naive. Disease activity (using the 28-joint count Disease Activity Score (DAS28)) and presence of antibodies against infliximab and adalimumab were assessed. Clinical response to adalimumab was compared between switchers and anti-TNF naive patients and their anti-infliximab and anti-adalimumab antibody status. Results After 28 weeks of adalimumab treatment the decrease in DAS28 (ΔDAS28) for the 235 patients was 1.6±1.5 (mean±SD). Anti-adalimumab antibodies were detected in 46 patients (20%). ΔDAS28 was 1.8±1.4 in patients without anti-adalimumab and 0.6±1.3 in patients with anti-adalimumab (p<0.0001). Thirty-three of the 52 switchers (63%) had anti-infliximab antibodies. Patients with anti-infliximab more often developed anti-adalimumab than anti-TNF naive patients (11 (33%) vs 32 (18%); p=0.039). ΔDAS28 was greater for anti-TNF naive patients (1.7±1.5) than for switchers without anti-infliximab antibodies (ΔDAS28=0.9±1.4) (p=0.009). ΔDAS28 for switchers with anti-infliximab was 1.2±1.3 and did not differ significantly from anti-TNF naive patients (p=0.262). Conclusion Switchers with anti-infliximab antibodies more often develop antibodies against adalimumab than anti-TNF naive patients. Response to adalimumab was limited in switchers without anti-infliximab antibodies, which raises the question whether a second anti-TNF treatment should be offered to patients with RA for whom an initial treatment with an anti-TNF blocker fails, in the absence of anti-biological antibodies.
Tracking performance of adaptively biased adaptive filters

Adaptive filters can improve their performance by exploiting the well-known tradeoff between bias and variance of the estimated solution. In a previous work, a scheme for adaptively biasing the filter weights was introduced, multiplying the output of a filter of any kind by a shrinking factor α ∈ [0, 1]. With an appropriate value α, such a scheme can reduce the steady-state error, especially for low signal-to-noise ratio (SNR). Here, we extend such analysis for a tracking scenario in which the optimal solution follows a random walk-model. We briefly review a realizable scheme for learning a, based on recently proposed algorithms for adaptive filter combination. Our experiments validate the accurateness of the analysis, and illustrate the performance gains that can be expected from these biased configurations in stationary and tracking scenarios.
Noise impact factor in the performance of interference-limited diversity combining antenna arrays

There is an abundant literature on the fully-analytical performance assessment of diversity combining arrays in the presence of interference, where the combining method is anything from scanning and selection diversity through optimum (MMSE) combining. However, in most of the literature and for the sake of analytic tractability, the noise is often assumed to be zero (high SNR assumption) in some portion of the derivation. The practical justification is that if the SNR is high enough and the system is interference-limited, then the impact of noise is negligible. This paper considers the case of a diversity combiner applying the zero-forcing criterion and operating under overloaded conditions, i.e. there are more impinging signals (desired plus interferers) than antenna elements. In this context, it is shown analytically that the output SINR can be factored into two components, namely the ideal SINR (whose distribution is already known) and the noise impact factor, whose distribution is derived herein. Furthermore, it is shown that the impact of the noise can be surprisingly significant in terms of BER in such scenarios.
Model Formulation: HL7 Clinical Document Architecture, Release 2

Clinical Document Architecture, Release One (CDA R1), became an American National Standards Institute (ANSI)-approved HL7 Standard in November 2000, representing the first specification derived from the Health Level 7 (HL7) Reference Information Model (RIM). CDA, Release Two (CDA R2), became an ANSI-approved HL7 Standard in May 2005 and is the subject of this article, where the focus is primarily on how the standard has evolved since CDA R1, particularly in the area of semantic representation of clinical events. CDA is a document markup standard that specifies the structure and semantics of a clinical document (such as a discharge summary or progress note) for the purpose of exchange. A CDA document is a defined and complete information object that can include text, images, sounds, and other multimedia content. It can be transferred within a message and can exist independently, outside the transferring message. CDA documents are encoded in Extensible Markup Language (XML), and they derive their machine processable meaning from the RIM, coupled with terminology. The CDA R2 model is richly expressive, enabling the formal representation of clinical statements (such as observations, medication administrations, and adverse events) such that they can be interpreted and acted upon by a computer. On the other hand, CDA R2 offers a low bar for adoption, providing a mechanism for simply wrapping a non-XML document with the CDA header or for creating a document with a structured header and sections containing only narrative content. The intent is to facilitate widespread adoption, while providing a mechanism for incremental semantic interoperability.
Large-vessel correlates of cerebral small-vessel disease

Objective: Our aim was to investigate the relationship of carotid structure and function with MRI markers of cerebral ischemic small-vessel disease. Methods: The study comprised 1,800 participants (aged 72.5 ± 4.1 years, 59.4% women) from the 3C-Dijon Study, a population-based, prospective cohort study, who had undergone quantitative brain MRI and carotid ultrasound. We used multivariable logistic and linear regression adjusted for age, sex, and vascular risk factors. Results: Presence of carotid plaque and increasing carotid lumen diameter (but not common carotid artery intima-media thickness) were associated with higher prevalence of lacunar infarcts: odds ratio (OR) = 1.60 (95% confidence interval [CI]: 1.09–2.35), p = 0.02 and OR = 1.24 (95% CI: 1.02–1.50), p = 0.03 (by SD increase). Carotid plaque was also associated with large white matter hyperintensity volume (WMHV) (age-specific top quartile of WMHV distribution): OR = 1.32 (95% CI: 1.04–1.67), p = 0.02, independently of vascular risk factors. Increasing Young elastic modulus and higher circumferential wall stress, reflecting augmented carotid stiffness, were associated with increasing WMHV (effect estimate [β] ± standard error: 0.0003 ± 0.0001, p = 0.024; β ± standard error: 0.005 ± 0.002, p = 0.008). Large WMHV was also associated with increasing Young elastic modulus (OR = 1.22 [95% CI: 1.04–1.42], p = 0.01) and with decreasing distensibility coefficient (OR = 0.83 [95% CI: 0.69–0.99], p = 0.04), independently of vascular risk factors. Associations of carotid lumen diameter with lacunar infarcts and of carotid stiffness markers with WMHV were independent of carotid plaque. Conclusions: In addition to and independently of carotid plaque, increasing carotid lumen diameter and markers of carotid stiffness were associated with increasing prevalence of lacunar infarcts and increasing WMHV, respectively.
Randomised controlled trial on whether advance knowledge of prostate-specific antigen testing improves participant reporting of unprotected sex

Objectives: To determine whether the process of informing research participants that they would be tested for the presence of a biological marker of semen exposure would reduce bias in their reports of unprotected sex. Methods: A randomised trial of 210 female sex workers from Mombasa, Kenya, was conducted, where half the group had advance knowledge (via the request for informed consent) that they would be tested for prostate-specific antigen (PSA) in their vaginal fluid before they reported on sex and condom use for the past 48 h. The other half were invited to participate (via additional informed consent) in the test for PSA after they had already consented to be questioned and reported on these sexual behaviours. A trained nurse instructed participants to self-swab to collect vaginal fluid specimens, which were tested for PSA using ELISA. Results: Reporting of unprotected sex did not differ between those with advance knowledge of the test for PSA and those without this knowledge (14.3% v 11.4%, respectively; p = 0.27). Surprisingly, more women with advance knowledge (15.8%) had discrepant self reports and PSA results than women without advance knowledge (9.1%); however, the difference was not statistically significant (OR 1.9; 95% CI 0.8 to 4.5). Conclusions: Knowing that one’s answers to a questionnaire could be verified with a biological marker of semen exposure did not make respondents more likely to report unprotected sex.
Expression and purification of RHC–EGFP fusion protein and its application in hyaluronic acid assay

ABSTRACT Hyaluronan is a widely distributed glycosaminoglycan which has multiple functions. Hyaluronic acid (HA) accumulation has been reported in many human diseases. Understanding the role of hyaluronan and its binding proteins in the pathobiology of disease will facilitate the development of novel therapeutics for many critical diseases. Current techniques described for the analysis of HA are mainly for HA quantification in solutions, not for the direct detection of HA in tissues or on cell surfaces. In our study, a fusion protein, named C-terminal domain of RHAMM–enhanced green fluorescence protein (RHC–EGFP), combined the HA-binding domain, C-terminal of receptor for hyaluronan-mediated motility, with EGFP, a widely used enhanced green fluorescence protein, was expressed and purified from Escherichia coli with high purity. Based on the sensitivity and convenience of fluorescence detection, methods for direct assay of HA in solutions, on cell surface or in tissues were established using RHC–EGFP. The binding specificity was also confirmed by competitive binding experiment and hyaluronidase degradation experiment. Our results provide an alternative choice for the specific and convenient assay of HA in various samples, and maybe helpful for further understanding of the fundamental and comprehensive functions of HA.
Predictors of adherence to a skill-building intervention in dementia caregivers.

BACKGROUND Treatment adherence is a widely recognized problem in health services but understudied in caregiver intervention research. This study examines caregiver sociodemographic and psychological characteristics, patient illness severity, and treatment implementation factors as predictors of caregiver adherence to a skills training intervention to help families manage dementia care problems at home. METHODS The sample consisted of 105 caregivers randomized to the Home Environmental Skill-Building Program at the Philadelphia site of the National Institutes of Health (NIH) Resources for Enhancing Alzheimer's Caregiver Health (REACH I). The intervention, implemented by occupational therapists, consisted of education, problem solving, communication, environmental and task simplification techniques, and home modifications. Adherence was measured by a proportion score representing the percentage of strategies used by participants compared to the total number of strategies prescribed during intervention (Strategy Use). RESULTS Regression analysis with intraclass correlation adjustment for interventionist effects revealed that caregivers with better physical health (p <.001), greater treatment exposure (p <.001), more problem areas addressed (p =.012), and for whom more active therapeutic techniques (role play) were used (p =.004) demonstrated greater adherence. Other caregiver characteristics, patient cognitive impairment, and troublesome behaviors were not significantly related to caregiver adherence. CONCLUSIONS Modifiable caregiver and treatment implementation factors, including active engagement of caregivers, were associated with adherence, whereas patient characteristics were not. Caregivers with poor health may be at risk for not benefiting from intervention, suggesting that efforts, including instruction in preventive care and allocating time to attend to their own health care needs, be directed towards improving their health.
Screening length in plasma winds

We study the screening length Ls of a heavy quark-antiquark pair in strongly coupled gauge theory plasmas flowing at velocity v. Using the AdS/CFT correspondence we investigate, analytically, the screening length in the ultra-relativistic limit. We develop a procedure that allows us to find the scaling exponent for a large class of backgrounds. We find that for conformal theories the screening length is (boosted energy density)−1/d. As examples of conformal backgrounds we study R-charged black holes and Schwarzschild-anti-deSitter black holes in (d+1)-dimensions. For non-conformal theories, we find that the exponent deviates from −1/d. As examples we study the non-extremal Klebanov-Tseytlin and Dp-brane geometries. We find an interesting relation between the deviation of the scaling exponent from the conformal value and the speed of sound.
Population Structure, Admixture, and Migration Patterns of Japanese Sika Deer (Cervus nippon) Inhabiting Toyama Prefecture in Japan

Rapid expansion of sika deer, in both number and distribution, in the Japanese Archipelago has resulted in serious ecological disturbance. In the present study, the population structure and migration patterns of sika deer (Cervus nippon) among Toyama and adjacent Prefectures were investigated using 11 polymorphic microsatellite loci. Deviation from Hardy–Weinberg equilibrium was detected in both total and individual regional sika deer samples from Toyama Prefecture. Results of pairwise FST results, factorial correspondence analysis, and STRUCTURE analysis indicated that sika deer in Toyama are not genetically distinct from those in adjacent Prefectures. Bayesian STRUCTURE results suggested the existence of two distinct clusters. However, multiple lines of genetic structure and high admixture were detected across the populations located in the central region of Toyama Prefecture. Both contemporary and historical migration analyses showed that dispersal into Toyama Prefecture from neighboring prefectures was high, especially migration from the prefecture on the east into Toyama Prefecture, and bidirectional dispersion between Toyama Prefecture and the prefecture to the south. Knowledge of such genetic structures and population dynamics is required for appropriate management and conservation of sika deer populations in the Japanese Archipelago.
Traditional Risk Factors in Patients With Severe , Mild to Moderate , and No Angiographic Coronary Stenosis

Background. To determine whether or not a moderate genetic defect of homocysteine metabolism is associated with the development of coronary artery disease, we studied the prevalence of thermolabile methylenetetrahydrofolate reductase, which is probably the most common genetic defect of homocysteine metabolism. Methods and Results. Three hundred thirty-nine subjects who underwent coronary angiography were classified into three groups: (1) patients with severe coronary artery stenosis (.701% occlusion in one or more coronary arteries or .50%o occlusion in the left main coronary artery), (2) patients with mild to moderate coronary artery stenosis (<70%o occlusion in one or more coronary arteries or <50%o occlusion in the left main coronary artery), and (3) patients with non-coronary heart disease or noncardiac chest pain (nonstenotic coronary arteries). The thermolability of methylenetetrahydrofolate reductase was prospectively determined in all subjects. Plasma homocyst(e)ine levels were then measured in those with thermolabile methylenetetrahydrofolate reductase. The traditional risk factors for coronary artery disease were thereafter ascertained by chart review of all subjects. The prevalence of thermolabile methylenetetrahydrofolate reductase was 18.1% in group 1, 13.4% in group 2, and 7.9%o in group 3. There was a significant difference between the prevalence of thermolabile methylenetetrahydrofolate reductase in groups 1 and 3 (P<.04). All individuals with thermolabile methylenetetrahydrofolate reductase irrespective of their clinical grouping had higher plasma homocyst(e)ine levels than normal (group 1, 14.86±5.85; group 2, 15.36±5.70; group 3, 13.39±3.80; normal, 8.50±2.8 nmol/mL). Nonetheless, there was no statistically significant difference in the plasma homocyst(e)ine concentrations of these patients with or without coronary artery stenosis. Using discriminant function analysis, thermolabile methylenetetrahydrofolate reductase was predictive of angiographically proven coronary artery stenosis. The traditional risk factorsage, sex, diabetes, smoking, hypercholesterolemia, and hypertension-were not significantly associated with the presence of thermolabile methylenetetrahydrofolate reductase. Conclsions. Thermolabile methylenetetrahydrofolate reductase is a risk factor for coronary artery disease and is unrelated to other risk factors. (Circulation. 1993;88[part 1]:1463-1469.)

LINEAR SPHERICITY TESTING OF 3-CONNECTED SINGLE SOURCE DIGRAPHS

It has been proved that sphericity testing for digraphs is an NP-complete problem. Here, we investigate sphericity of 3- connected single source digraphs. We provide a new combinatorial characterization of sphericity and give a linear time algorithm for sphericity testing. Our algorithm tests whether a 3-connected single source digraph with n vertices is spherical in O(n) time.
Clamping of switch peak voltage with diode and transformer at output of class E amplifier

In this paper, a voltage clamp circuit consists of diode and transformer, which reduces the transient peak switch voltage of the class E amplifier with single dc power supply, is proposed. This clamp circuit clamps the output voltage of the class E amplifier when the amplitude of output voltage goes over the maximum permissible value. Simulation results showed that the proposed diode clamp circuit successfully reduces the transient peak switch voltage.
An Approach to the Measurement, Analysis, and Prediction of Brand Equity and Its Sources

The authors propose a new approach for measuring, analyzing, and predicting a brand's equity in a product market. Brand equity is defined as the incremental contribution ($) per year obtained by the brand in comparison to the underlying product (or service) with no brand-building efforts. The incremental contribution is driven by the individual customer's incremental choice probability for the brand in comparison to his choice probability for the underlying product with no brand-building efforts. The approach takes into account three sources of brand equity-brand awareness, attribute perception biases, and nonattribute preference-and reveals how much each of the three sources contributes to brand equity. This is done by taking into account not only the direct effects of these three sources on choice probabilities, but also the indirect effects through enhancing the brand's availability. The method provides what-if analysis capabilities to predict the likely impacts of alternative strategies to enhance a brand's equity. The survey-based results from applying the method to the digital cellular phone market in Korea show that the proposed approach has good face validity and convergent validity, with brand awareness playing the largest role, followed by nonattribute preference.
Distributing cognitive resources in one-against-many strategy games

Many real-world situations require an agent with limited cognitive resources to be engaged in multiple games simultaneously. In these circumstances, the agent is unable to devote infinite cognitive resources to represent the optimal strategy that needs to be played against each opponent. We investigate this type of game, where a player, called the focal player, playing concurrently against multiple opponents independent 2-player games. Nevertheless, these games are coupled through the shared memory resource available to the agent. Each opponent has a fixed strategy. While the history length may vary from one opponent to another, the focal player doesn't know the opponents' strategies or which history length is used by which opponent. All the focal player can observe is the opponents' actions. We use evolutionary computation to decide on an appropriate allocation of memory to opponents. We show - given that opponents are using fixed strategies - that the memory distribution relies on the number of active bits (i.e., bits which generates a repeated pattern with a favorable payoff) that the focal player needs to exploit its opponents' strategies. We show how our current results relate to the minimum required number of bits for a player to face a set of opponents with fixed strategies, and how the number of active bits increases as the richness of the opponent strategy - measured using entropy - increases.
Blastocyst Axis Is Specified Independently of Early Cell Lineage But Aligns with the ZP Shape

The mechanisms controlling the establishment of the embryonic-abembryonic (E-Ab) axis of the mammalian blastocyst are controversial. We used in vitro time-lapse imaging and in vivo lineage labeling to provide evidence that the E-Ab axis of the mouse blastocyst is generated independently of early cell lineage. Rather, both the boundary between two-cell blastomeres and the E-Ab axis of the blastocyst align relative to the ellipsoidal shape of the zona pellucida (ZP), an extraembryonic structure. Lack of correlation between cell lineage and the E-Ab axis can be explained by the rotation of the embryo within the ZP.
