Enhanced Data Security Using Neural Network in Cloud Environment

Cloud is an on-demand computing service which provides a dynamic environment for end users to assure Quality of Service (QoS) on data for its confidentiality in cloud data centers. A set of information from a cloud database with a high security level accessing data is said to be Confidentiality. The proposed research work is a new cloud data security model, A Neural Data Security Model (NDSM) to ensure the high confidentiality and security in cloud data storage environment. This cloud Data Security Model is implemented using Dynamic Hashing Fragmented Component. The dynamic hashing concept is implemented for storing the fragmented sensitive data. The neural cryptographic algorithm is used in the data security model to deal with data encryption for sensitive data to enhance the confidentiality level. This work couples of cloud database that achieves high confidentiality on data security.
Spontaneous Activity as a Determinant of Axonal Connections

To investigate the role of spontaneous retinal activity in map refinement, we studied goldfish kept in darkness during regeneration of a cut optic nerve. In one experiment, such fish (with lenses ablated to blur vision) were maintained for 70 days in stroboscopic light, diurnal light, or total darkness interrupted daily by 15 minutes of stroboscopic light. The retinotectal projection was then assessed for retinotopy by standard methods, using retrograde transport of wheat germ agglutinin—horseradish peroxidase. As in previous work, significantly more refinement was found in diurnal than in stroboscopic light. In darkness, refinement was as complete as in diurnal light. In a second experiment, similar fish were kept in stroboscopic light for 63 days. Some were then assessed to confirm that refinement had been delayed, while others were transferred to darkness or diurnal light for assessment later. After 7 days in either environment, no further refinement was seen; but after 21 days, substantial and significant refinement has occurred in both. Thus the effects of darkness and diurnal light were indistinguishable, and very different from those of stroboscopic light and (in previous studies) tetrodotoxin. Map refinement is evidently activity‐dependent but not experience‐dependent, and can effectively use the correlated spontaneous firing of neighbouring ganglion cells as its basis. Locally correlated spontaneous activity, which appears also to drive eye‐ and class‐specific axon segregation in mammals, occurs widely in the nervous system. It could potentially generate systematic interconnection patterns even between neuronal populations without an overtly topographic organization.
Shrouds: Optimal Separating Surfaces for Enumerated Volumes

We describe new techniques for computing a smooth triangular mesh surface that surrounds an enumerated volume consisting of a collection of points from a 3D rectilinear grid. The surface has the topology of an isosurface computed by a marching cubes method applied to a field function that has the value one at the points in the volume and zero for points not in the volume. The vertices are confined to the edges of the grid that penetrate this separating surface and the precise positions are computed so as to optimize a certain energy functional applied to the surface. We use efficient iterative methods to compute the optimal separating surfaces. We lift the concept of energy functionals for planar curves to isosurfaces by means of the 4*-network which is a unique collection of orthogonal planar polygons lying on the isosurface. The general strategy that we describe here leads to methods that are simple, efficient, and effective.
Plant Responses to Climate Change: The Case Study of Betulaceae and Poaceae Pollen Seasons (Northern Italy, Vignola, Emilia-Romagna)

Aerobiological data have especially demonstrated that there is correlation between climate warming and the pollination season of plants. This paper focuses on airborne pollen monitoring of Betulaceae and Poaceae, two of the main plant groups with anemophilous pollen and allergenic proprieties in Northern Italy. The aim is to investigate plant responses to temperature variations by considering long-term pollen series. The 15-year aerobiological analysis is reported from the monitoring station of Vignola (located near Modena, in the Emilia-Romagna region) that had operated in the years 1990–2004 with a Hirst spore trap. The Yearly Pollen Index calculated for these two botanical families has shown contrasting trends in pollen production and release. These trends were well identifiable but fairly variable, depending on both meteorological variables and anthropogenic causes. Based on recent reference literature, we considered that some oscillations in pollen concentration could have been a main effect of temperature variability reflecting global warming. The duration of pollen seasons of Betulaceae and Poaceae, depending on the different species included in each family, has not unequivocally been determined. Phenological responses were particularly evident in Alnus and especially in Corylus as a general moving up of the end of pollination. The study shows that these trees can be affected by global warming more than other, more tolerant, plants. The research can be a contribution to the understanding of phenological plant responses to climate change and suggests that alder and hazelnut trees have to be taken into high consideration as sensible markers of plant responses to climate change.
Phylogenetic analyses provide the first insights into the evolution of OVATE family proteins in land plants.

BACKGROUND AND AIMS The OVATE gene encodes a nuclear-localized regulatory protein belonging to a distinct family of plant-specific proteins known as the OVATE family proteins (OFPs). OVATE was first identified as a key regulator of fruit shape in tomato, with nonsense mutants displaying pear-shaped fruits. However, the role of OFPs in plant development has been poorly characterized. METHODS Public databases were searched and a total of 265 putative OVATE protein sequences were identified from 13 sequenced plant genomes that represent the major evolutionary lineages of land plants. A phylogenetic analysis was conducted based on the alignment of the conserved OVATE domain from these 13 selected plant genomes. The expression patterns of tomato SlOFP genes were analysed via quantitative real-time PCR. The pattern of OVATE gene duplication resulting in the expansion of the gene family was determined in arabidopsis, rice and tomato. KEY RESULTS Genes for OFPs were found to be present in all the sampled land plant genomes, including the early-diverged lineages, mosses and lycophytes. Phylogenetic analysis based on the amino acid sequences of the conserved OVATE domain defined 11 sub-groups of OFPs in angiosperms. Different evolutionary mechanisms are proposed for OVATE family evolution, namely conserved evolution and divergent expansion. Characterization of the AtOFP family in arabidopsis, the OsOFP family in rice and the SlOFP family in tomato provided further details regarding the evolutionary framework and revealed a major contribution of tandem and segmental duplications towards expansion of the OVATE gene family. CONCLUSIONS This first genome-wide survey on OFPs provides new insights into the evolution of the OVATE protein family and establishes a solid base for future functional genomics studies on this important but poorly characterized regulatory protein family in plants.
On the Concept of Optimality Interval

The approximants to regular continued fractions constitute `best approximations' to the numbers they converge to in two ways known as of the first and the second kind. This property of continued fractions provides a solution to Gosper's problem of the batting average: if the batting average of a baseball player is 0.334, what is the minimum number of times he has been at bat? In this paper, we tackle somehow the inverse question: given a rational number P/Q, what is the set of all numbers for which P/Q is a `best approximation' of one or the other kind? We prove that in both cases these `Optimality Sets' are intervals and we give a precise description of their endpoints.
Peirce and Piaget: A Commentary on Signs of a Common Ground

The scholarly works of Charles S. Peirce and Jean Piaget are now more than ever before beginning to have a significant effect on attempts to derive adequate theories pertaining to the nature of a general sign system and the acquisition of a lexicon (linguisticallybased sign system), respectively. In line with the overall purpose of this brief study, it will be proposed below that the likelihood of obtaining success in the derivation of such theories in part will correspond to the degrees of interrelatedness granted these two phenomena. To those philosophers, developmental psychologists, and psycholinguists who are interested in the pursuit of such theories and who are at the same time familiar with the contributions of Peirce and Piaget, the question of interrelatedness should pose few, if any, serious problems. Presently, however, what appears to be a potentially insurmountable problem does exist. Namely, there are few researchers who are sufficiently familiar with the Peircean and Piagetian literature to the point where an integrated approach can be taken in efforts to characterize what might be common to the function and development of sign and lexical systems. A review of the literature concerning lexical acquisition, for instance, will quickly reveal a lack of Peircean influence in contrast to an obvious Piagetian influence. As will be discussed later, the exclusion of Peirce, although not too surprising given the separation of disciplines, is particularly unfortunate when contemplating the breadth of Peirce's theory of signs along with the plausible assumption that if a theory of lexical acquisition is to be reasonably adequate it must be embedded in a unified theory of signs.
High-Risk Driving Behaviors among Adolescent Binge Drinkers

Background: Binge drinking is common among adolescents. Alcohol use, particularly binge drinking, has been associated with neurocognitive deficits and increased risk-taking behaviors, which may contribute to negative driving outcomes among adolescents even while sober. Objectives: To examine potential differences in self-reported risky driving behaviors between adolescent binge drinkers and a matched sample of controls on measures of (1) compliance with graduated licensing laws, (2) high-risk driving behaviors, and (3) driving outcomes (i.e., crashes, traffic tickets). Methods: This study examined driving behaviors and outcomes in adolescent recent binge drinkers (n = 21) and demographically and driving history matched controls (n = 17) between the ages of 16–18 years. Results: Binge drinkers more frequently violated graduated licensing laws (e.g., driving late at night) and engaged in more “high-risk” driving behaviors, such as speeding and using a cell phone while driving. Binge drinkers had more traffic tickets, crashes, and “near crashes” than the control group. Speeding was the behavior most associated with crashes within the binge drinkers. Conclusion: In this study, binge-drinking teens consistently engage in more dangerous driving behaviors and experience more frequent crashes and traffic tickets. They are also less compliant with preventative restrictions placed on youth while they are learning critical safe driving skills. Scientific Significance: These findings highlight a need to examine the contribution of underlying traits (such as sensation seeking) and binge-related cognitive changes to these high-risk driving behaviors, which may assist researchers in establishing alternative prevention and policy efforts targeting this population.
Steganalysis of LSB encoding in color images

Analyzes the security of least significant bit (LSB) embedding for hiding messages in high-color-depth digital images. We introduce a powerful steganalytic technique that enables us to reliably detect the presence of a pseudorandom binary message randomly spread in a color image. We estimate the probability of both false detections and missing a secret message. The method is based on statistical analysis of the image colors in the RGB cube. It is shown that, even for secret message capacities of 0.1-0.3 bits per pixel, it is possible to achieve a high degree of detection reliability.
Associative image retrieval using knowledge in encyclopedia text

Applying existing keyword retrieval to image retrieval causes some problems. Among them, database developers must describe photograph contents in detail and adequate retrieval is difficult. These problems have been resolved by developing an associative retrieval technology using not keyword's but semantic vectors as a retrieval method with an associative function such as a human being possesses. A semantic vector dictionary of more than 100,000 words was made from encyclopedia text. This paper explains the experimental image retrieval system for 36,000 photographs with the semantic vector dictionary made from the encyclopedia text. This system associates the words input by a user with the knowledge in the encyclopedia text and outputs ranked retrieval results. The effectiveness of this associative retrieval method is confirmed by evaluating content retrieval of images by a small benchmark and making an adaptive learning function of semantic vectors in the case in which a retrieval result is not the same as a user's subjective perspective would impose.
Follow-Up Data of a Prospective Study Obesity and Binge Eating Disorder : Short-and Long-Term A Cognitive-Behavioral Therapeutic Program for Patients With

The goal of this study is to investigate the efficacy of a manualized cognitivebehavioral therapeutic (CBT) approach for patients with obesity and binge eating disorder (BED) on the short and longer term. A prospective study without a control group consisting of three measurements (a baseline measurement and two follow-up assessments up to 5 years after the start of the CBT treatment) was used. A total of 56 patients with obesity and BED (age = 39.7 ± 10-9 years; body mass index [BMI] = 38.5 ± 8.3 kg/m) participated in the study. BMI, number of binges per week, general psychological well-being, mood, attitude toward one’s body, and loss of control over the eating behavior were evaluated by means of mixed models. Results indicate that a CBT approach offered 1 day a week during an average 7 months at OCCIDENTAL COLLEGE LIBRARY on October 28, 2012 bmo.sagepub. com Downloaded from Vanderlinden et al. 671 produces benefits on eating behaviors, weight, and psychological parameters that are durable up to 3.5 years post treatment.
Study on the Promotional Factors of Extended Producer Responsibility

With the enforcement of "Circular Economy Promotion Law", extended producer responsibility has become the important institution of China's circular economy. However, incentives for the majority of producers are lacking. This paper starts with EPR's theoretical base, clarifying its environmental goals and responsibility modes. Five promotional factors are deduced, which are improvement potential of product's environmental performance, feedback to product redesign, closed-loop recyclability, cost-benefit certainty and service substitutability. The promotional strategy of China's EPR is then discussed.
Development of a clinical examination in non-specific low back pain: a Delphi technique.

OBJECTIVE To establish the discriminatory items of the clinical examination of non-specific low back pain, important to physiotherapists. DESIGN A focus group and Delphi technique with UK physiotherapists. SUBJECTS A purposive sample of 30 physiotherapists attended a focus group and completed 3 rounds of Delphi questionnaires. METHODS Data were analysed using mixed qualitative and quantitative approaches. A frequency content analysis identified commonly identified tests and questions, whilst the Delphi consensus technique assumed consensus had been reached with greater than 80% agreement on item inclusion or exclusion. RESULTS The focus group established the structure of the clinical examination with 15 domains of questioning or physical testing. Three rounds of Delphi questionnaires established the important items of the clinical examination. The list of tests and questions included items evaluating both the psychosocial and biomedical status of the patient as well as questions screening for red flags. CONCLUSION This is the first work to establish discriminatory tests in the clinical examination of non-specific low back pain, important to physiotherapists. The clinical examination will subsequently be evaluated for item validity and data will undergo cluster analysis. The items of this clinical examination may provide evidence for the existence of homogenous sub-groups within the heterogeneous non-specific low back pain diagnosis.
Uma abordagem cognitiva para auto-configuração de protocolos de comunicação

A medida que novas tecnologias de rede sao desenvolvidas, torna-se mais complexa a tarefa de gerenciar os servicos e protocolos de comunicacao. Diante de tal complexidade, a gerencia das redes de comunicacao atuais representa um grande desafio. As solucoes de gerencia tradicionais, com uma arquitetura centralizada, nao apresentam um alto grau de escalabilidade e nao sao capazes de prover reconfiguracao dinâmica dos protocolos de comunicacao em reposta as constantes mudancas nas condicoes da rede. Neste trabalho, apresenta-se uma solucao factivel e eficaz para auto-configuracao de protocolos de comunicacao. Propoe-se uma abordagem cognitiva para a reconfiguracao dinâmica de parâmetros de protocolos a fim de evitar a degradacao de desempenho resultante de eventuais alteracoes nas condicoes da rede. O arcabouco proposto, denominado CogProt, prove, atraves de mecanismos de aprendizagem e decisao, o ajuste de parâmetros dos protocolos durante a operacao da rede. Parâmetros de interesse sao periodicamente reconfigurados de acordo com informacoes de monitoramento a fim de aumentar o desempenho medio do sistema como um todo. A abordagem proposta e descentralizada e pode ser aplicada no ajuste dinâmico de uma ampla variedade de protocolos em diferentes camadas da arquitetura da rede. Apresenta-se uma serie de estudos de caso para ilustrar a aplicacao da abordagem proposta. Estudos baseados em simulacao e um experimento em um ambiente de rede real foram realizados para avaliar o desempenho do arcabouco CogProt. Os resultados demonstram a eficacia da abordagem proposta em reagir prontamente as mudancas no estado da rede e melhorar o desempenho medio dos protocolos. Abstract
Quasielastic and inelastic neutron scattering investigation of fragile-to-strong crossover in deeply supercooled water confined in nanoporous silica matrices

We investigated, using quasi-elastic and inelastic neutron scattering, the slow single-particle dynamics of water confined in laboratory synthesized nanoporous silica matrices, MCM-41-S, with pore diameters ranging from 10 to 18 Å. Inside the pores of these matrices, the freezing process of water is strongly inhibited down to 160 K. We analysed the quasi-elastic part of the neutron scattering spectra with a relaxing-cage model and determined the temperature and pressure dependence of the Q-dependent translational relaxation time and its stretch exponent β for the time dependence of the self-intermediate scattering function. The calculated Q-independent average translational relaxation time shows a fragile-to-strong (FS) dynamic crossover for pressures lower than 1600 bar. Above this pressure, it is no longer possible to discern the characteristic feature of the FS crossover. Identification of this end point with the predicted second low-temperature critical point of water is discussed. A subsequent inelastic neutron scattering investigation of the librational band of water indicates that this FS dynamic crossover is associated with a structural change of the hydrogen-bond cage surrounding a typical water molecule from a denser liquid-like configuration to a less-dense ice-like open structure.
Quantum electrodynamics in superconducting artificial atoms

Cette these porte sur deux problemes theoriques d'electrodynamique quantique en circuits supraconducteurs. Nous avons d'abord etudie les conditions d'obtention du couplage fort entre un resonateur et une distribution continue d'emetteurs elargie de facon inhomogene. Le developpement de ce formalisme est fortement motive par les recentes propositions d'utiliser des ensembles de degres de liberte microscopiques pour realiser des memoires quantiques. En effet, ces systemes beneficient du couplage collectif au resonateur, tout en conservant les proprietes de relaxation d'un seul emetteur. Nous discutons l'influence de l'elargissement inhomogene sur l'existence et les proprietes de coherence des pics polaritoniques obtenus dans le regime de couplage fort. Nous constatons que leur coherence depend de facon critique de la forme de la distribution et pas uniquement de sa largeur. En tenant compte de l'elargissement inhomogene, nous avons pu simuler avec une grande precision de nombreux resultats experimentaux pionniers sur un ensemble de centres NV. La modelisation s'est revelee un outil puissant pour obtenir les proprietes des ensembles de spins couples a un resonateur. Nous proposons egalement une methode originale de mesure de l'etat de qubits Josephson fondee sur un SQUID DC avec une inductance de boucle elevee. Ce systeme est decrit par un atome artificiel avec des niveaux d'energie en forme de diamant ou nous definissons les qubits logique et ancilla couples entre eux par un terme Kerr croise. En fonction de l'etat du qubit logique, l'ancilla est couplee de maniere resonante ou dispersive au resonateur, ce qui provoque un contraste important dans l'amplitude du signal micro-onde transmis par le resonateur. Les simulations montrent que cette methode originale peut etre plus rapide et peut aussi avoir une plus grande fidelite que les methodes actuellement utilisees dans la communaute des circuits supraconducteurs.
The ESS in an asymmetric generalized war of attrition with mistakes in role perception.

We derive the ESS for the generalized asymmetric war of attrition, where payoffs to contestants may vary in time and may depend on some characteristic, called the "role" of an individual. We use the same approach as Hammerstein & Parker (1982), who examined an asymmetric war of attrition. We consider two roles, A and B. Role A is assumed to be favoured with respect to payoffs. It is assumed that there is always a true asymmetry, so in each contest one individual has role A and the other has role B. It is assumed that roles are assigned to contestants at random and that they can make mistakes in role perception. It is shown that, under certain assumptions about shapes of payoff functions and probabilities of making mistakes, there is an ESS which can be characterized by two probability distributions with non-overlapping support. Individuals who perceive their role as A should choose larger persistence times. This ESS structure is similar to that in the asymmetric war of attrition. In that model, the resource values and the cost rates are constant. We consider situations where all these values may change in time and where rewards and costs may be equal after some finite time. Such shapes of payoff functions arise naturally in competitive patch depletion (Sjerps & Haccou, 1994a,b). As a result, the probability density functions that specify the conditional strategies are no longer necessarily negative exponentials (as in the war of attrition), but may have very different shapes. Furthermore, under some conditions there is a maximum persistence time, at which there can be an atom of probability. We give explicit expressions as well as numerical approximations for the ESS.
