Hybrid security protocol for wireless body area networks

Wireless body area networks (WBANs) are receiving a significant interest as an emerging technology in next generation wireless networks. Security challenges as well as this interest are also beginning to rise to the surface. We derived specific security requirements from WBANs, and proposed a new hybrid security protocol for WBANs which satisfies these requirements. This proposed protocol dealt with the overall security including up to the in- on-, and out-body, and utilized two heterogeneous cryptosystems (the symmetric and asymmetric) for diverse environments of WBANs. Our protocol shows that it satisfies more security requirements than existing security protocols including the overall coverage of WBANs. Copyright © 2010 John Wiley & Sons, Ltd.

A study of methylated polyadenylic acid.

Copolymers with different contents of adenine and N1-methyl adenine residues have been studied, polyadenylic acid being methylated by dimethylsulfate. Thermal stability, circular dichroism and light scattering measurements are in favor of a two-strand structure at neutral pH. Thermal stability of these products is much less sensitive to ionic strength than that of most polynucleotides, and in some cases independent of ionic strength. These copolymers interact or not with poly(U), depending on the percentage of N1-methyl adenine residues. Copolymers with high contents of methyladenine interact with poly(A) at neutral pH. These copolymers do not bind DNA-dependent RNA polymerase. Some results at acid pH are also reported.
Notice of RetractionResearch on structural design of vehicle engine mount

In order to research engine mount design method, this paper took a engine mount design project as example, and designed vehicle engine mount model by CATIA combined with objective working conditions of engine, using MATLAB to made mode decoupling and stiffness calculation based on engine working characteristics. Engine dynamics simulation was conducted by ADAMS, and obtained stress state of mount, calculated mount structure strength utilizing FEM. The calculation results indicate that the deformation displacements of all the mounts are in the scope limited by the allowed safe distance, the Von Mises Stress of mounts are all less than the material yield stress, so mount design meets the requirement, design methods is applicable. Therefore, this paper provide a mount design flow for vehicle engineering.
Developmental changes in the embodied self of spatial perspective taking.

Spatial perspective taking consists of mental self-rotation and other cognitive information processing. Mental self-rotation is a process of rotating an embodied representational self through mental simulation of the sensorimotor mechanisms underlying actual self-movement. It was predicted that physical development would affect the operation of the representational self. One hundred and twenty-five individuals aged 5-80 years (57 children, 35 students, and 33 elderly people) executed a video game task of spatial perspective taking in three conditions of sensorimotor activation: A restrained, stable, and unstable condition. In the linear function formulas considering the degree of rotation and response times, the gradient represented the theoretical speed of mental self-rotation and the intercept represented other cognitive processing. A significant interaction was found between age group and condition on the gradients, indicating that the response times in the unstable condition were faster than in the other conditions for the children, the restrained condition was slower than the other conditions for the students, while no difference was found for the elderly adults. The results suggest that the influence of sensorimotor activation on the embodied representational self depends on developmental changes in physical control.
Influence of Cultural Conditions on the Use of ICT for Learning: Differences among Erasmus and National Students at Spanish University

The use of technology is widespread in all areas of life, particularly among young people and particularly in learning environments. In this sense, college students have incorporated these technologies in different media and used them for many years. The use of ICT among students taking the same subjects is very different because of the sociological diversity thereof and, in particular, their different cultures and countries. This is the case of Erasmus students, who must take the same subjects and with the same instruments than the national ones. Although both groups must show the same academic performance, their conditions are very diverse, including difficulties related to language. This article analyzes the relationship between learning styles active, reflexive, theoretical and pragmatic and the use of ICT in training university students, comparing between Erasmus and domestic ones. The REATIC survey was conducted among 37 third-year students from the Faculty of Economics and Business of the University of A Coruna Spain, distinguished four different modules: knowledge of ICT, use of ICT, assessment of ICT and ICT as learning style. Results showed differences in all modules and especially in the last module that analyzes the use of ICT for learning.
Feedback networks between microRNAs and epigenetic modifications in urological tumors

Epigenetic modifications and microRNAs are known to play key roles in human cancer. For urological tumors, changes in epigenetic modifications and aberrant microRNA profiles have been reported. However, the mechanisms of epigenetic and microRNA regulation are not entirely separable. Increasingly, recent research in these fields overlaps. There seems to be a complicated feedback interrelationship between epigenetic and microRNA regulation that must be highly controlled. Disruptions of this feedback network can have serious consequences for various biological processes and can result in cellular transformation. Investigation of the network between microRNAs and epigenetics could lead to a better understanding of the processes involved in development and progression of urological tumors. This understanding could provide new approaches for the development of novel individualized therapies, which are adjusted to the molecular pattern of a tumor. In this review, we present an overview of microRNA-epigenetic circuits acting in urological tumors.
Permittivity enhancement and dielectric relaxation of doped hafnium and zirconium oxide

The frequency dispersion of La doped zirconia and cerium doped hafnia films is considered. Doping at concentration of approximately 10% stabilizes crystalline phases with higher-k values. The dielectric relaxation of La doped zirconia films is more severe than the cerium doped hafnia.
Polyploidy in Archaea and Bacteria: About Desiccation Resistance, Giant Cell Size, Long-Term Survival, Enforcement by a Eukaryotic Host and Additional Aspects

During recent years, it has become clear that many species of archaea and bacteria are polyploid and contain more than 10 copies of their chromosome. In this contribution, eight examples are discussed to highlight different aspects of polyploidy in prokaryotes. The species discussed are the bacteria Azotobacter vinelandii, Deinococcus radiodurans, Sinorhizobium meliloti, and Epulopiscium as well as the archaea Methanocaldococcus jannaschii, Methanococcus maripaludis, Haloferax volcanii, and haloarchaeal isolates from salt deposits. The topics include possible laboratory artifacts, resistance against double-strand breaks, long-term survival, relaxation of DNA segregation and septum formation, enforced polyploidy by a eukaryotic host, genome equalization by gene conversion, and the nongenetic usage of genomic DNA as a phosphate storage polymer. Together, the selected topics give an overview of the biodiversity of polyploidy in archaea and bacteria.
MIKC* MADS Domain Heterodimers Are Required for Pollen Maturation and Tube Growth in Arabidopsis1[W][OA]

MADS box genes encode transcription factors that play important regulatory roles at various stages in plant development. Transcripts encoding the MIKC*-type (for MADS DNA-binding domain, Intervening domain, Keratin-like domain, and C-terminal domain) factors, a divergent clade, are enriched in mature pollen. Previous studies have shown that these proteins bind DNA as heterodimers, which form between S- and P-class MIKC* proteins. In this study, Arabidopsis (Arabidopsis thaliana) pollen with little or no MIKC* activity was produced by combining strong loss-of-function alleles of the S-class proteins AGAMOUS-LIKE66 (AGL66) and AGL104. Double mutant plants produce pollen but have severely reduced fertility due to reduced pollen viability, delayed germination, and aberrant pollen tube growth. Microarray analysis of the mutant pollen revealed that the loss of MIKC* regulation has a major impact on pollen gene expression. Pollen competition assays involving various combinations of AGL65, AGL66, AGL104, and AGL94 mutant alleles provided genetic evidence that at least three heterodimers (AGL30-AGL104, AGL65-AGL104, and AGL30-AGL66) form and function in at least a partially redundant fashion in pollen. Analyses of transcript abundance in wild-type and mutant pollen indicated that AGL65-containing complexes are likely to be more abundant than the others and that accumulation of AGL30 and AGL94 transcripts increases in response to reductions in MIKC* activity. These results were combined to create a model to describe MIKC* heterodimer contributions in pollen.
The reflection and transmission of Lamb waves across a rectangular crack as a function of the crack geometry

This paper is to derive the reflection and transmission coefficients of Lamb waves incident on a rectangular crack in an elastic plate by means of small local matrices. The repeated and sequential scattering phenomenon at the crack is analyzed by introducing three independent processes according to the boundary shape of the crack and the direction of the wave propagation. Several local wave form matrices are composed to represent the scattering characteristics of each process, and the reflection and transmission coefficients of a multimode Lamb wave are calculated across the crack per each scattering cycle. By the superposition rule, the transmitted and reflected waves from all the cycles are summed to determine the overall steady state responses at the crack boundary. Efficacy of the method is illustrated by determining the transmission and reflection coefficients of S0 and A0 mode waves incident on a crack in an aluminum plate as functions of crack dimensions.

Characterization of the Xp21-23 region in the wood lemming, a region involved in XY sex reversal.

The wood lemming (Myopus schisticolor) harbors two types of X chromosome, a normal X and a variant X, designated X*. The X* chromosome contains a mutation that causes XY sex reversal. We have previously demonstrated that the Xp21-23 region is deleted from X* and is associated with XY sex reversal. To further analyze the deleted region, we have constructed and characterized seven X chromosome- and region-specific recombinant DNA libraries. Further, we have screened mouse fetal gonad cDNA libraries with the microdissected Xp21-23 DNA as a probe in an attempt to identify homologous and expressed sequences from the deletion. Fourteen positive clones were isolated, and sequence analyses showed that ten of these contained identical sequences homologous to mouse gamma-satellite sequences. One of the remaining four was perfectly homologous to the mouse gene Ccth (chaperonin containing t-complex polypeptide 1, eta subunit). Southern blot indicated that the Ccth cDNA was located on the X chromosome, not deleted from the X* but closely linked to the deletion region. Although the role of the Ccth containing region in sex determination of the wood lemming requires additional studies, the isolation of the mouse Ccth gene by the deletion Xp21-23 probe could be important since this gene is mainly expressed in testis.
Biochemistry, genetics, and applications of exopolysaccharide production in Streptococcus thermophilus: a review.

Many strains of Streptococcus thermophilus synthesize extracellular polysaccharides. These molecules may be produced as capsules that are tightly associated with the cell, or they may be liberated into the medium as a loose slime (i.e., "ropy" polysaccharide). Although the presence of exopolysaccharide does not confer any obvious advantage to growth or survival of S. thermophilus in milk, in situ production by this species or other dairy lactic acid bacteria typically imparts a desirable "ropy" or viscous texture to fermented milk products. Recent work has also shown that exopolysaccharide-producing S. thermophilus can enhance the functional properties of Mozzarella cheese, but they are not phage-proof. As our understanding of the genetics, physiology, and functionality of bacterial exopolysaccharides continues to improve, novel applications for polysaccharides and polysaccharide-producing cultures are likely to emerge inside and outside the dairy industry. This article provides an overview of biochemistry, genetics, and applications of exopolysaccharide production in S. thermophilus.
Immediate Effects of Reiki on Heart Rate Variability, Cortisol Levels, and Body Temperature in Health Care Professionals With Burnout

Burnout is a work-related mental health impairment comprising three dimensions: emotional exhaustion, depersonalization, and reduced personal accomplishment. Reiki aims to help replenish and rebalance the body’s energetic system, thus stimulating the healing process. The objective of this placebo-controlled, repeated measures, crossover, single-blind, randomized trial was to analyze the immediate effects of Reiki on heart rate variability (HRV), body temperature, and salivary flow rate and cortisol level in health care professionals with burnout syndrome (BS). Participants included 21 health care professionals with BS, who were asked to complete two visits to the laboratory with a 1-week interval between sessions. They were randomly assigned the order in which they would receive a Reiki session applied by an experienced therapist and a placebo treatment applied by a therapist with no knowledge of Reiki, who mimicked the Reiki treatment. Temperature, Holter ECG recordings (standard deviation of the normal-to-normal interval [SDNN], square root of mean squared differences of successive NN intervals [RMSSD], HRV index, low frequency component [LF], and high frequency component [HF]), salivary flow rate and cortisol levels were measured at baseline and postintervention by an assessor blinded to allocation group. SDNN and body temperature were significantly higher after the Reiki treatment than after the placebo. LF was significantly lower after the Reiki treatment. The decrease in the LF domain was associated with the increase in body temperature. These results suggest that Reiki has an effect on the parasympathetic nervous system when applied to health care professionals with BS.
Estimation of lipid peroxidation and lipid profile levels in Type II Diabetes Mellitus patients of Kashmir valley

processes are involved in the development of diabetes. Abstract The lipid profile levels were found to be elevated in T2DM diabetic patients. The study was designed to find out the correlation between lipid peroxidation, lipid profile and T2DM. Degree of lipid peroxidation was measured in terms of malondialdehyde (MDA) along with lipid profile and blood glucose in diabetes mellitus. Totally 50 known diabetic patients and 50 non-diabetic controls were studied. Significant increase in Malondialdehyde (MDA) and lipid profile, except HDL cholesterol, which is decreased, has been found in Type 2 diabetes mellitus (T2DM) cases as compared to controls. It has also been observed that the level of lipid peroxide increased as per the increase in concentration of blood glucose. The increase in lipid peroxidation in the hyperglycemic condition may be explained, as the superoxide dismutase enzyme an antioxidant becomes inactive due the formation of superoxide radical within the cell. The lipid peroxidation leads to the damage of the tissues and organs which results in complications in diabetic patients. So in chronic diabetic cases, secondary complications are well marked. High levels of total cholesterol, TGs and LDL may appear may be due to increased cholesterol synthesis. It may be concluded that good metabolic control of hyperglycemia will prevent in the peroxidation and the lipid metabolism, which may help in good prognosis and preventing the manifestation of vascular and secondary complications in diabetes mellitus.
Recast density and acquisition of novel irregular past tense verbs.

PURPOSE Children with specific language impairment (SLI) lag behind children with typical language (TL) in their grammatical development, despite equivalent early exposure to recasts in conversation (M. E. Fey, T. E. Krulik, D. F. Loeb, & K. Proctor-Williams, 1999) and the ability to learn from recasts in intervention as quickly as do children with TL (K. E. Nelson, S. Camarata, J. Welsh, L. Butovsky, & M. Camarata, 1996). This experiment tested whether this apparent paradox could be attributed to variations in the density of recasts in conversation versus intervention. METHOD Thirteen children (7-8 years of age) with SLI and 13 language-similar children (5-6 years of age) with TL were exposed to 3 recast densities of novel irregular past tense verbs (none, conversation-like, intervention-like) over 5 sessions. Outcomes were based on spontaneous conversational productions and a post-test probe. RESULTS As predicted, at conversation-like densities, children with TL more accurately produced the target verbs they heard in recasts than in nonrecast models (d = 0.58), children with SLI showed no differences, and children with TL produced the verbs more accurately than did children with SLI (d = 0.54). Contrary to expectations, at higher intervention-like recast densities, the SLI group did not improve their accuracy, and the TL group performances were significantly poorer (d = 0.47). CONCLUSION At conversational levels, recasts facilitated greater verb learning than models alone but only in the TL group. Increasing recast density to the modest levels in this brief intervention experiment did not benefit children with SLI and led to poorer learning for children with TL. To optimize learning, efficiency of recast distribution as well as rate must be considered.
Evaluation of the Intel Sandy Bridge-EP server processor

In this paper we report on a set of benchmark results recently obtained by CERN openlab when comparing an 8-core “Sandy Bridge-EP” processor with Intel’s previous microarchitecture, the “Westmere-EP”. The Intel marketing names for these processors are “Xeon E5-2600 processor series” and “Xeon 5600 processor series”, respectively. Both processors are produced in a 32nm process, and both platforms are dual-socket servers. Multiple benchmarks were used to get a good understanding of the performance of the new processor. We used both industry-standard benchmarks, such as SPEC2006, and specific High Energy Physics benchmarks, representing both simulation of physics detectors and data analysis of physics events.
Polysemy, syntax, and variation: a usage-based method for cognitive semantics

The study of polysemy has a venerable tradition in Cognitive Linguistics. Since the pioneering of work of Dirven ( 98 ), Radden ( 98 ), Brugman ( 983), Lindner ( 983), and Vandeloise ( 984), the Lexical Network approach to spatial prepositions has proved to be one of the most important contributions of the cognitive paradigm. However, at both a theoretical and methodological level, this network approach to sense variation has recently come under fire. This study examines a methodological proposal that answers some of the criticisms that a cognitive approach to polysemy faces. The basic premise is to conserve the network model, but to complement this with another method: a corpus-driven quantified and multifactorial method. Such an approach employs a kind of componentional analysis that identifies clusters of features across large numbers of speech events. In other words, rather than analyse the possible meanings of a lexeme, a polysemic network should “fall out” from an analysis that identifies clusters of the cognitive-functional features of a lexeme’s usage. These features do not in any way resemble those of the Structuralist componentional analyses, since they are not based on a hypothetical semantic system, but describe instances of real language usage and are based upon encyclopaedic semantics of that language use in context. This usage-based approach is gaining wide currency in Cognitive Linguistics, attested by the wide range of edited volumes dedicated to the subject (Gries and Stefanowitsch 006; Stefanowitsch and Gries 006; Zeschel 008; Glynn and Fischer in press; Newman and Rice in press; Glynn and Robinson forthcoming). We will refer to this approach as the Quantitative Multifactorial method. The discussion begins by briefly covering the current state of the art of polysemy study in cognitive linguistics, where we underline the need for the implementation of this method and how it may cooperate with existing analytical models. In Section , the discussion moves to the description of the Quantitative Multifactorial method, and finally the third section examines a case study of the English lexeme hassle.
Glial fibrillary acidic protein is necessary for mature astrocytes to react to beta-amyloid.

Upregulation of the glial fibrillary acidic protein (GFAP) in astrocytes is a hallmark of the phenomenon known as reactive gliosis and, yet, the function of GFAP in this process is largely unknown. Our previous studies have shown that mature astrocytes react vigorously to substrate bound beta-amyloid protein (BAP) in a variety of ways (i.e., increased GFAP, enhanced motility, unusual aggregation patterns, inhibitory ECM production). In order to uncover which, if any, of these phenomena are causally related to the function of GFAP, primary cortical astrocytes from transgenic mice lacking GFAP were cultured on BAP substrates at low or high density and at various lengths of time following in vitro maturation. Differences between mutant and control cells became progressively more obvious when cells were matured in vitro for two weeks or longer and especially in cultures that were at high density. Mature control astrocytes show a dramatic response to BAP by aggregating into a meshwork of rope-like structures that completely bridge over the peptide surface. In marked contrast, mature GFAP-null astrocytes initiate the response much more slowly and had a much reduced ability to aggregate tightly. Furthermore, we prepared hippocampal slice cultures from GFAP-/- and GFAP+/+ mice and compared their astrocytic responses to injected BAP. GFAP-/- astrocytes of hippocampal slice cultures failed to form a barrier-like structure around the edge of the BAP deposit as did GFAP+/+ astrocytes. Our data suggest that GFAP may be essential for mature astrocytes to constrain certain types of highly inflammatory lesions in the brain.
