Management Technique for Protection of Sensitive Data at Proxy Level for SQL based Databases using NIST Recommended SP 800-132

Protecting confidentiality of organizational sensitive data in outsourced databases is continuously raising security concerns. The activities of malicious administrator and malicious software attacks on database server while data in use are alarming security concerns in the outsourced database servers. Therefore data needs to be protected in its complete life cycle (at rest, in transition and while in use) to realize better confidentiality for the outsourced databases. Data must be in encrypted form in the premises of database service providers even at the time of computations on data i.e. all the possible computation performed on encrypted data without decrypting in the premises of service providers. CryptDB is a practical and provable solution from MIT towards providing the confidentiality for relational databases by supporting the computations on encrypted data at database server side. For shared data, among different users, CryptDB use application’s access control policy at the level of SQL queries in the proxy and each principal encryption key is encrypted with his password and for shared sensitive data owner’s key is encrypted separately with all authorized users key and stored in the proxy and principal key is accessed with password key chaining technique. In this paper, we are proposing a stateless Key management technique in contrast to state full key management of CryptDB at the proxy level to protect sensitive data of users along with shared data for out sourced SQL databases using NIST recommended SP800-132.This approach eliminates the storing of user assigned encryption keys and also speak for relation keys in the proxy.
Introduction to coherent spaces Arnold Neumaier

The notion of a coherent space is a nonlinear version of the notion of a complex Euclidean space: The vector space axioms are dropped while the notion of inner product is kept. Coherent spaces provide a setting for the study of geometry in a different direction than traditional metric, topological, and differential geometry. Just as it pays to study the properties of manifolds independently of their embedding into a Euclidean space, so it appears fruitful to study the properties of coherent spaces independent of their embedding into a Hilbert space. Coherent spaces have close relations to reproducing kernel Hilbert spaces, Fock spaces, and unitary group representations, and to many other fields of mathematics, statistics, and physics. This paper is the first of a series of papers and defines concepts and basic theorems about coherent spaces, associated vector spaces, and their topology. Later papers in the series discuss symmetries of coherent spaces, relations to homogeneous spaces, the theory of group representations, C-algebras, hypergroups, finite geometry, and applications to quantum physics. While the applications to quantum physics were the main motiviation for developing the theory, many more applications exist in complex analysis, group theory, probability theory, statistics, physics, and engineering.

Morphological and molecular evidence for two new species of Padina (Dictyotales, Phaeophyceae), P. sulcata and P. calcarea, from the central Indo-Pacific region

NI-NI-WIN, Hanyuda T. , Draisma S.G. A. , Verheij E. , Prud'homme van Reine W.F. , Lim P.-E. , Phang S. -M. , and Kawai H. 2012. Morphological and molecular evidence for two new species of Padina (Dictyotales, Phaeophyceae), P. sulcata and P. calcarea, from the central Indo-Pacific. Phycologia 51: 576–585. DOI: 10.2216/11-94.1 Two new species of Padina – 1. Padina sulcata sp. nov. and 2. P. calcarea sp. nov. – from Malaysia, Indonesia and Palau were described based on morphological and molecular phylogenetic observations. Padina sulcata was a three-layered species characterised by a covering of thick fibrous hairs from the base to the middle of the inferior surface (away from the in-rolled margin) of the thallus; conspicuous equally spaced hairlines that alternated between both frond surfaces; and broad, indusiate oogonial and tetrasporangial sori that occupied nearly the entire fertile zones, and the fertile zones were separated by sterile zones of equal width. Padina calcarea was a two-layered species characterised by a bright yellow inferior surface and a thick calcification on the superior surface (facing to the in-rolled margin), which imparted a strikingly whitish color; inconspicuous hairlines were confined to the inferior surface; and indusiate tetrasporangial sori were just above the hairlines and were found only on the inferior surface. Molecular phylogenetic analyses used chloroplast rbcL and mitochondrial cox3 gene sequences and revealed that the two new species each form strongly supported clades that were genetically distant. Padina calcarea formed an isolated clade that made an early divergence; whereas, P. sulcata showed a sister relationship to P. ryukyuana, indicating a more recent divergence. Padina calcarea was very similar to the Hawaiian P. melemele in gross appearance, particularly in the bright orange to yellow color of the inferior thallus surface and the heavy calcification on the superior surface. However, they were distinguished mainly by the position and arrangement of reproductive sori that were found on the inferior surface and located just above the hairlines in P. calcarea but that were found on the superior surface between the hairlines of the opposite surface in P. melemele. Molecular phylogenetic analyses did not reflect the morphological similarity of the two species because they occupied two distantly related clades.
BIOMEDICAL IMAGE ANALYSIS USING SELF-ORGANIZING MAPS

The implementation of self organizing map (SOM) and its application to the analysis of biomedical images are presented. The SOM algorithm was implemented in MATLAB program suite with various optional parameters enabling the adjustment of the model according to the user’s requirements. For easier application of SOM the graphical user interface has been developed. The segmentation and edge detection procedures are critical steps in the analysis of biomedical images, enabling for instance the detection of the abnormal structure or the recognition of different types of tissue. The self-organizing map provides a quick and easy approach for these tasks with satisfying quality of outputs, which has been verified using the high-resolution CT images capturing the expressions of the Granulomatosis with polyangiitis (GPA) disease.
A neural parser as a direct classifier for head-final languages

This paper demonstrates a neural parser implementation suitable for consistently head-final languages such as Japanese. Unlike the transition- and graph-based algorithms in most state-of-the-art parsers, our parser directly selects the head word of a dependent from a limited number of candidates. This method drastically simplifies the model so that we can easily interpret the output of the neural model. Moreover, by exploiting grammatical knowledge to restrict possible modification types, we can control the output of the parser to reduce specific errors without adding annotated corpora. The neural parser performed well both on conventional Japanese corpora and the Japanese version of Universal Dependency corpus, and the advantages of distributed representations were observed in the comparison with the non-neural conventional model.

Interannual variation of soil respiration in two New England forests

Soil respiration is an important component of the annual carbon balance of forests, but few studies have addressed interannual variation in soil respiration. The objectives of this study were to investigate the seasonal and interannual variation in soil respiration, temperature, precipitation, and soil water content in two New England forest soils and to develop and evaluate empirical models for predicting variations in soil respiration using temperature and soil moisture content. We have been measuring soil respiration, using dynamic chambers in well‐drained upland sites and poorly drained wetland sites since 1995 at the Harvard Forest, Massachusetts, and since 1996 at the Howland Forest, Maine. The upland sites had consistently greater rates of respiration than wetlands. Prolonged drought periods in 1995, 1998, and 1999 at the Harvard Forest resulted in decreased soil respiration rates in the uplands, particularly once soil moisture contents decreased below about −150 kPa. In contrast, wetland respiration increased upon drying. The interannual variation in soil respiration at the Harvard Forest, 0.23 kg C m−2 yr−1, exceeds the interannual variation in net ecosystem exchange (NEE), 0.14 kg C m−2 yr−1 previously measured for this forest, indicating that interannual variation in soil respiration can have an important influence on NEE. Interannual variation was lower at the Howland Forest, and the effects of low soil moisture content on respiration rates were more subtle. The onset of spring was variable among years at both forests, owing to variation in both temperature and precipitation, and contributed to 33–59% of the annual variability in total carbon release. At the upland sites, parameterization of empirical regression models for respiration as a function of soil temperature was inconsistent among years, indicating an important effect of interannual variation in soil water content. The negative residuals of the Harvard Forest temperature regression model were best explained by drought conditions (soil matric potentials ≤−150 kPa). This function was only applicable during severe drought and did not account for less severe dry periods that also reduced soil moisture and soil respiration. An empirical regression model for the wetlands as a function of temperature was significantly improved with the addition of a soil moisture function, which increased respiration rates under dry conditions and decreased it under wet conditions. Climatic changes resulting in drier conditions will likely decrease soil respiration rates in uplands and increase soil respiration in wetlands.
Graphene/Li-ion battery

Density function theory calculations were carried out to clarify storage states of Lithium (Li) ions in graphene clusters. The adsorption energy, spin polarization, charge distribution, electronic gap, surface curvature, and dipole momentum were calculated for each cluster. Li-ion adsorbed graphene,doped by one Li atom is spin polarized, so there would be different gaps for different spin polarization in electrons. Calculation results demonstrated that a smaller cluster between each two larger clusters is preferable, because it could improve grapheneLi-ion batteries; consequently, the most proper graphene anode structure has been proposed.
Molecular phylogeny of the brown algal genera Akkesiphycus and Halosiphon (Laminariales), resulting in the circumscription of the new families Akkesiphycaceae and Halosiphonaceae

Abstract Phylogenetic relationships of Akkesiphycus lubricum with the Laminariales and related taxa were assessed by molecular phylogenetic analyses based on the Rubisco large subunit gene (rbcL), internal transcribed spacer regions (ITS1 and ITS2), and 18S ribosomal DNA (18s rDNA) sequence data. Among the three data sets, rbcL gene sequences gave the best resolution for indicating familial and ordinal relationships within the Laminariales and related taxa. Using rbcL data, Akkesiphycus showed the closest phylogenetic relationship to the Pseudochordaceae (Laminariales) and this was also supported by ITS and 18S rDNA data. The clade of Akkesiphycus and the Pseudochordaceae formed a sister group to the Alariaceae/Laminariaceae/Lessoniaceae group and the Chordaceae of the Laminariales in maximum parsimony and neighbour-joining analyses. Morphologically, Akkesiphycus differs significantly from other Laminariales in having gametophytes with anisogamous planogametes. However, considering that some laminarialean species have residual flagella in eggs and the close phylogenetic relationship with the Pseudochordaceae, as demonstrated in the present study, we propose to establish a new family, the Akkesiphycaceae Kawai & Sasaki fam. nov., to accommodate A. lubricum; we place it in the order Laminariales. The Akkesiphycaceae is distinct in having foliose sporophytes with multicellular paraphyses and monomorphic dioecious gametophytes that form anisogametes. As a result of inclusion of the Akkesiphycaceae, the ordinal definition of the Laminariales has to be emended to include anisogamy. On the other hand, the distant phylogenetic relationship between Halosiphon and Chordaceae, suggested previously by ITS and 18S rDNA data, was confirmed by rbcL data, and hence, a second new family, the Halosiphonaceae Kawai & Sasaki fam. nov. is described, although its ordinal assignment needs further discussion. The family Halosiphonaceae is characterized by having simple, cord-shaped sporophytes with multicellular assimilators and monoecious oogamous gametophytes.
A Provider-Friendly Serverless Framework for Latency-Critical Applications

Serverless is an important step in the evolution of cloud computing. First virtualisation enabled sharing a physical machine, then containers enabled sharing an operating system, now serverless targets sharing a runtime. Serverless platforms allow users to build distributed systems from individual functions, knowing little about the underlying infrastructure. They are free from concerns around configuration, maintenance and scalability. Meanwhile providers guarantee timely execution in a secure, isolated environment with pay-as-you-execute billing. Although many prominent serverless platforms exist there are still several significant open problems. The most notable is the highly variable performance seen by users, which goes hand-inhandwith unpredictable resource consumption seen by the provider. Another sticking point is the almost universal lack of statefulness, which precludes many applications. Containers are used extensively to provide an isolated environment for serverless functions, but introduce undesirable overheads and obstruct sharing resources. I plan to build a new multi-tenant serverelss language runtime focused on low overheads and resource reuse, using lightweight isolation built into the runtime itself. This has potential to greatly reduce variance in latency, improve resource efficiency and allow for smarter scheduling decisions. I will also investigate native support for stateful functions backed by distributed remote memory, hence opening the door to previously unfeasible data-intensive applications.
Establishing a Calculation Method for Estimating the Normal Circumference of the Proximal Interphalangeal Finger Joints

Objective: To estimate the normal circumference of the interphalangeal (IP) thumb joint and the proximal IP (PIP) joints from the index finger to the little finger using individual physical parameters such as body height and body weight. Methods: The maximum size on the ring gauge was recorded which caused resistance when the IP joint of the thumb or PIP joints of the index to small fingers were passed through the gauge. RG was defined as the ring gauge number with the same diameter as the circumference of the IP thumb joint and PIP finger joints from the index finger to the little finger. There were 300 healthy subjects and 600 hands. Univariate and multivariate analyses were used to analyze the relationships between RG and the parameters of age, sex, height, weight, and dominant hand, and regression equations were derived. Results: Age, sex and body weight were all statistically significant predictive factors of RG in all fingers. R2, the coefficient of determination in the regression equation, was almost 0.7 for all fingers, indicating that a moderate or strong correlation was observed between RG and the regression equation. Conclusions: The circumference of the IP thumb joint and PIP finger joints from the index finger to the little finger can be estimated in healthy individuals using a calculation formula that takes age, sex, body height and body weight into account.
Form-function relationships in a marine foundation species depend on scale : a shoot to global perspective from a distributed ecological experiment

Form–function relationships in plants underlie their ecosystem roles in supporting higher trophic levels through primary production, detrital pathways, and habitat provision. For widespread, phenotypically‐variable plants, productivity may differ not only across abiotic conditions, but also from distinct morphological or demographic traits. A single foundation species, eelgrass Zostera marina , typically dominates north temperate seagrass meadows, which we studied across 14 sites spanning 32–61°N latitude and two ocean basins. Body size varied by nearly two orders of magnitude through this range, and was largest at mid‐latitudes and in the Pacific Ocean. At the global scale, neither latitude, site‐level environmental conditions, nor body size helped predict productivity (relative growth rate 1–2% day‐1 at most sites), suggesting a remarkable capacity of Z. marina to achieve similar productivity in summer. Furthermore, among a suite of stressors applied within sites, only ambient leaf damage reduced productivity; grazer reduction and nutrient addition had no effect on eelgrass size or growth. Scale‐dependence was evident in different allometric relationships within and across sites for productivity and for modules (leaf count) relative to size. Zostera marina provides a range of ecosystem functions related to both body size (habitat provision, water flow) and growth rates (food, carbon dynamics). Our observed decoupling of body size and maximum production suggests that geographic variation in these ecosystem functions may be independent, with a future need to resolve how local adaptation or plasticity of body size might actually enable more consistent peak productivity across disparate environmental conditions.
Size-dependent electric voltage controlled magnetic anisotropy in multiferroic heterostructures: Interface-charge and strain comediated magnetoelectric coupling

We present a phenomenological scheme to study the size-dependent electric voltage-controlled magnetic anisotropy in ferromagnetic (FM) and ferroelectric (FE) heterostructures. The FM layers are either metallic [Fe(001), Ni(001), Co(0001)] or half-metallic [(La, Sr)MnO${}_{3}$] films. Two magnetoelectric mechanisms, i.e., interface-charge and strain-mediated couplings, are considered. We show that the interface-charge-mediated coupling is the main mechanism for the magnetoelectic coupling when the FM film thickness is below a certain transition thickness ${d}_{\mathrm{tr}}$ while the strain-mediated coupling dominates above ${d}_{\mathrm{tr}}$.
Data-driven Recovery of Hand Depth using Conditional Regressive Random Forest on Stereo Images

Hand pose is emerging as an important interface for human-computer interaction. This paper presents a data-driven method to estimate a high-quality depth map of a hand from a stereoscopic camera input by introducing a novel superpixelbased regression framework that takes advantage of the smoothness of the depth surface of the hand. To this end, we introduce Conditional Regressive Random Forest (CRRF), a method that combines a Conditional Random Field (CRF) and a Regressive Random Forest (RRF) to model the mapping from a stereo RGB image pair to a depth image. The RRF provides a unary term that adaptively selects different stereo-matching measures as it implicitly determines matching pixels in a coarse-to-fine manner. While the RRF makes depth prediction for each super-pixel independently, the CRF unifies the prediction of depth by modeling pair-wise interactions between adjacent superpixels. Experimental results show that CRRF can generate a depth image more accurately than the leading contemporary techniques using an inexpensive stereo camera.
Exploring university students’ use of technologies beyond the formal learning context: A tale of two online platforms

Situated within an informal learning context, this study examines how a group of pre-service teachers in Hong Kong use Facebook and Google Sites on their own initiative to fulfil their academic and socio-emotional needs during their teaching practice. Also included in the study are the motivating and inhibiting factors that influence student online participation. Guided by an informal learning model and the literature relating to online participation and sense of community, this exploratory study generates its findings from questionnaires, individual interviews and online postings. The results show that the Google Sites created an avenue for the students to share a range of self-developed teaching resources and ideas. Facebook is a more interactive platform through which the participants seek peer support, exchange teaching ideas, and engage in discussions on a variety of topics. Structure and control provided by Google Sites and immediacy and interactivity afforded by Facebook become complementary to each other.
Apparent Survival of Adult Thayer's and Glaucous Gulls Nesting Sympatrically in the Canadian High Arctic

We estimated apparent survival of 33 adult Thayer's Gulls Larus thayeri and 21 adult Glaucous Gulls Larus hyperboreus nesting sympatrically at a small colony on St. Helena Island, Nunavut, in Canada's high Arctic, using five consecutive years (2003–2007) of capture-mark-resight data. Resighting probabilities were high in all years for both species (0.97). Mean survival for Thayer's (0.81 ± 0.05) was low, but for Glaucous Gulls (0.86 ± 0.05) was comparable to estimates of survival reported for large gulls elsewhere. Both species showed high annual variation in survival, with one year each of noticeably lower survival, suggesting that some factors acting on survival may have differed between species and could reflect different species' exposure to natural or anthropogenic stressors. Our findings contribute to the limited demographic information on these polar gulls, and provide a basis for future comparisons should they be affected by changes in their polar environments.
