A Novel Preserving Client Privacy and Designate Verifier Auditing Scheme for Cloud Storage
Jiang Xu,Wenliang Chen,Sai Ji,Yongjun Ren,Jin Wang 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.1
Cloud storage is now an important development trend in information technology. To ensure the integrity of data storage in cloud storing, researchers have present some proof of storage schemes. In some cases, the ability to check data possession is delegated by data owners. Hence, the delegable provable data possession and proxy provable data possession are proposed. However the schemes are not secure since the proxy or designated verifier stores some delegation information in cloud storage servers. In this paper, we propose PC-DV POS scheme, which can preserve clients’ privacy and designate a verifier by the client signed the data blocks. In particular, we utilize group signatures and key exchange to construct homomorphic authenticators, so that only the designated verifier is able to check the integrity of shared data for users without retrieving the entire data, and cannot reveal the identities of signers on all blocks in shared data.

<P><B>Abstract</B></P> <P>Pathogenesis of Parkinson’s disease (PD) is undoubtedly a multifactorial phenomenon, with diverse etiological agents. Pro-inflammatory mediators act as a skew that directs disease progression during neurodegenerative diseases. Understanding the dynamics of inflammation and inflammatory mediators in preventing or reducing disease progression has recently gained much attention. Inflammatory neuro-degeneration is regulated via cytokines, chemokines, lipid mediators and immune cell subsets; however, individual cellular phenotypes in the Central Nervous System (CNS) acts in diverse ways whose persistent activation leads to unresolving inflammation often causing unfavorable outcomes in neurodegenerative disease like PD. Specifically, activation of cellular phenotypes like astrocytes, microglia, activation of peripheral immune cells requires different activation signals and agents like (cytokines, misfolded protein aggregates, infectious agents, pesticides like organophosphates, etc.,). However, what is unknown is how the different cellular phenotypes respond uniquely and the role of the factors they secrete alters the signal cascades in the complex neuron-microglial connections in the CNS. Hence, understanding the role of cellular phenotypes and the inflammatory mediators, the cross talk among the signals and their receptors can help us to identify the potential therapeutic target using natural products. In this review we have tried to put together the role of cellular phenotypes as a skew that favors PD progression and we have also discussed how the lack of experimental approaches and challenges that affects understanding the cellular targets that can be used against natural derivatives in alleviating PD pathophysiology. Together, this review will provide the better insights into the role of cellular phenotypes of neuroinflammation, inflammatory mediators and the orchestrating factors of inflammation and how they can be targeted in a more specific way that can be used in the clinical management of PD.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Distinct cellular Phenotypes acts uniquely in the pathogenesis of PD. </LI> <LI> Inflammation can be cause and consequence of PD pathogenesis. </LI> <LI> Flavonoids regulate multiple modulators of inflammation in mitigating PD pathology. </LI> <LI> Diverse intrinsic/extrinsic mediators converge together in glial activation in exacerbating PD pathology. </LI> </UL> </P>

Orthotropic steel decks(OSD’s) are prone to fatigue cracking under cyclic loads, especially for rib-to-deck welded connection and rib-to-crossbeam welded connection. To reveal fracturing behaviors of these fatigue-prone sites, a multi-scale model of OSD’s specimen is established, including segmental shell-element part and local solid-element configuration. Based on the extended finite element method(XFEM), propagation analysis was carried out in this research. The analysis of stress intensity factor (SIF) shows that the crack at the weld root or weld toe of the rib-to-deck welded connection is a mixed-crack with modes I, II and III, where mode I plays a leading role. Besides, the maximum SIF KI of the crack at the weld toe is slightly larger than that at the weld root. For rib-to-crossbeam welded connection, the maximum SIF KI at the weld toe of the U-rib is greater than that at the weld toe of the crossbeam. The analysis of crack propagation shows that the crack growth rate at the weld toe is faster than that at the weld root with the same initial crack size and loading conditions. Similarly, for rib-to-crossbeam welded connection, the crack propagation at the weld toe of U-rib performs faster than that at the weld toe of crossbeam.

Objective: Connections between chronic inflammation and tumor development and progression are now generally accepted. Recent evidence indicates that hepatitis B is associated with several types of cancer, but whether endometrial carcinoma (EC) is included has not been reported. Methods: We analyzed HBV serum marker status in 398 patients with endometrial cancer, comparing them to 788 control women undergoing health examination. Results: The total prevalence of HBsAg tested positive in cancer group was significantly higher than the control group (12.8% vs 6.0%, P=0.001), while positive HBsAb was significantly lower (41.2% vs 68.5%, P=0.001). Hepatitis B carriers in endometrial cancer group were also more frequent than in the control group (9.3% vs 5.5%, P=0.013). Interestingly, in the endometrial cancer group, 147 cases were HBV serum marker negative, which was also higher than in the control group (36.9% vs 15.6%, P=0.001). Conclusion: There may be a correlation between HBV infection and endometrial carcinoma.

<P>The concession period is one of the most important issues in the contractual arrangement of build-operate-transfer (BOT) projects. When planning a BOT project, the government should aim for a trade-off between the concerned government's satisfaction and the private concessionaire's profit. The objective of this paper is to present a discrete stochastic process model to obtain an optimal concession period considering the trade-off. The process model is developed for a highway project by analyzing the actual traffic data. The net present value (NPV) is calculated for use as a constraint condition that indicates the boundary of risk preference in a utility function. Using a utility function, this paper estimates the duration of concession periods at which the government can both attract investments from private concessionaires and satisfy public opinion. A numerical simulation is applied to demonstrate the applicability of the methodology presented. The result of the simulation shows that the discrete stochastic process model contributes to a better understanding of trade-offs in determining the optimal concession period.</P>

In a honey bee colony, worker bees rear a newqueen by providing herwith a larger cell inwhich to develop and alarge amount of richer food (royal jelly). Royal jelly and worker jelly (fed to developing worker larvae) differ interms of sugar, vitamin, protein and nucleotide composition. Here we examined whether workers attendingqueen andworker larvae are separate specialized sub-castes of the nurse bees.We collected nurse bees attendingqueen larvae (AQL) and worker larvae (AWL) and compared gene expression profiles of hypopharyngeal glandtissues, using Solexa/Illumina digital gene expression tag profiling (DGE). Significant differences in gene expressionwere found that included a disproportionate number of genes involved in glandular secretion and royal jellysynthesis. However behavioral observations showed that thesewere not two entirely distinct populations. Nurseworkers were observed attending both worker larvae and queen larvae, and there was no evidence of a specializedgroup of workers that preferentially or exclusively attended developing queens. Nevertheless, AQL attendedlarvaemore frequently compared toAWL, suggesting that nurses sampled attending queen larvaemay have beenthe most active nurses. This study serves as another example of the relationship between differences in gene expressionand behavioral specialisation in honey bees.
