DeyPoS-homomorphism authenticated tree (HAT) for multi-user locality in cloud storage

The technology PoS (Dynamic Proof of storage) is a cryptographic primordial allows a abuser to test the reliability of subcontracted documents and effectively replace documents in the cloud storage system. Despite the fact that investigators have projected several dynamic proofs of storage designs in distinct client settings, hassle in the multi-client settings have now not been examined adequately. In sensible multi-client cloud server storage space wishes a cozy client part cross client system of deduplication, it permits client toward bypass importing manner as well as gain instantly the rights of the files, while different vendors of the same files hold uploaded to the cloud system server. In the direction of familiarity not a bit of prevailing dynamic Proof of Storages can guide this system. This research article we are bring the model of dynamic proof of storage in deduplicatable system and endorse a green creation known as Dedupicatable Dynamic Proof of Storage (DeyPoS), on the way to attain DeyPoS and comfy reduplication concurrently in cross client. Taking into account confront of formation assortment and personal blot creation make use of a new tool called HAT (Homomorphic Authenticated Tree). Also verify precautions of creation and the hypothetical, investigational outcomes shows that the creation is green in use.
Numerical investigation of different cavitation regimes with the use of Large Eddy Simulations

In this paper we present a numerical framework in the Large Eddy Simulation context for modelling cavitation dynamics at various back pressures. The focus is on cavitation present in micro-orifices such as modern fuel injectors. The numerical simulation of the two-phase flow is performed following the so called "one-fluid approach". Two different models for the estimation of the volume of fluid function α are assessed. The main difference between the two models tested, is that Model 1 relies on the solution of an additional equation for tracking α with source terms to account for phase change while Model 2 is based on local phase and thermodynamic equilibrium assumptions that allow the formation of a parameter free equilibrium model. Results in terms of void fraction and pressure will be compared with the experimental data from [7]. Moreover, since cavitation is a phenomenon affected considerably by eddies that occur on similar time and length scales as the bubble dynamics, the sensitivity of the predictions to the turbulence models used is assessed.
Autonomous Logistic Processes of Bike Courier Services using Multiagent-Based Simulation

We present an agent-based approach for solving pickup and delivery problems (PDP) in dynamic environments and show its application by bike couriers in urban districts. To avoid social conflicts, the focus is on the computation of fair allocations of orders to bike couriers who are paid by commission fees. We realize autonomous logistic processes and present a mulitagent system with specially adapted negotiation mechanisms. In addition, we apply the mulitagent-based simulation platform PlaSMA for modeling, simulating, and evaluating different transport scenarios within the transport infrastructure of the city of Bremen, Germany. The customer orders are based on real data provided by a German bike courier company. The results show that the approach indeed improves the fairness of distributions significantly. Finally, we present a new business model for a commercial online dispatching platform enabled by our approach.
Evapotranspiration from Douglas fir stands exposed to soil water deficits

The rate of evapotranspiration from thinned and unthinned stands of Douglas fir was measured using energy and water balance methods. At high values of soil water storage in the root zone the evapotranspiration rate was approximately 80% of the equilibrium evaporation rate. Below a critical value of soil water storage the ratio of the evapotranspiration rate to the equilibrium evaporation rate (E/Eeq) tended to decrease linearly with decreasing soil water storage. The critical values of soil water storage in the root zone were 11.8 and 8.3 cm for the thinned and unthinned stand, respectively. Below these critical storage values, there was approximately 3.5 cm of water remaining in both root zones that was extractable by the trees. The relationship between E/Eeq and the fraction of extractable water in the root zone for both stands was very similar for sunny days. In this relationship, E/Eeq began to decrease when there was approximately 40% of the extractable water remaining in the root zones of both stands.
Spatial distribution of four spruce bark beetles in north-western Slovakia

Infestation density of four the most common spruce bark beetle species was estimated on 15 study sites (10 trees per site) in the Kysuce model region in 2006. Five half-metre long sections of the stem were selected and dissected at the base of the stem; midway between the base of the stem and the base of the crown; just below the base of the crown; in the middle of the crown; and in the upper part of the crown. The infestation density of bark beetles, expressed as the number of mating chambers per dm 2 , was determined. Ordinary kriging was then used to produce smooth maps and visualize spatial distribution of study species. Maps with isolines indicating high infestation were produced for study species ( I. typographus over 0.38; I. amitinus over 0.15; I. duplicatus over 0.11; and P. chalcographus over 0.415 nuptial chambers per dm 2 ). Ips typographus L. remained dominant species on majority of sites having high intensity of infestation. Lower altitudes in the south-eastern part of the region were often infested by I. duplicatus Sahlberg and also by I. typographus and Pityogenes chalcographus L. Higher elevations in the north-eastern part of territory in the vicinity of border with Poland were heavily infested by I. amitinus Eichhoff (often with I. typographus). P. chalcographus was abundant on majority of territory - mainly in southern half of area. However locally, it was found in extremely high abundance. The results suggest the need for control measures set up jointly against the most abundant bark beetle species in study region.
On a unified fatigue modelling for structural analysis based on the shakedown concept

One of the main goals in structural design is to avoid rupture due to fatigue. During a long period, and still now, engineers used simple stress approaches. Uniaxial criteria like S-n curves, goodmann-Haigh diagrams, KtKf concept are sufficient when the stresses are derived by using analytical elastic approaches like beam theory. The generalization of FEM calculations make possible to characterise with more accuracy the stress and strain state near the hot spots of mechanical structures. They are most of the time complex: numerous mechanical components experience in service multiaxial repeated varying stresses where two or more principal stresses fluctuate with time (i.e. they vary with time but they may also rotate like in the rolling contact fatigue). Multiaxial fatigue criteria are then needed in order to make fatigue calculations. Early multiaxial fatigue criteria are derived by using equivalent stress or strain based on static yield theories obtained by replacing the static von Mises or Tresca stress by an “amplitude” of von Mises or Tresca stress. These approaches often qualified as empirical may be non conservative for out of phase loading paths.
Embutido Multiprocessador DRM Analysis Using a Simulator of a Multiprocessor Embedded System

Multiprocessor systems are an emerging technology. The Hijdra project being developed at NXP semiconductors Research is a multiprocessor system running with both hard and soft real time streaming media jobs. These jobs consist of multiple tasks running on embedded multiprocessors. Finding good solutions for job mapping is the main problem of these systems. One application which has being studied for Hijdra is the “Car Radio”. This thesis concerns the study of a digital radio receptor application (DRM) in Hijdra architecture. In this context, a data flow model of analysis was extracted from the application, the latency introduced by the addition of a new tile (Viterbi accelerator) and eventual speed gains were studied and the possibility of mapping the different tasks of the application in different processors was foreseen. Many strategies were yet to be defined in order to optimize the application performance so it can work more effectively in the multiprocessor system.
COMPARISON OF GILA TOPMINNOW AND WESTERN MOSQUITOFISH AS BIOLOGICAL CONTROL AGENTS OF MOSQUITOES

Abstract I compared acute tolerance of Gila topminnow, Poeciliopsis occidentalis, and western mosquitofish, Gambusia affinis, to ammonia and high water temperature and also compared diet, food selectivity, and impact on invertebrate populations to evaluate the potential for each species to effectively control mosquitoes (Culicidae) in wetland habitats. Critical thermal maxima differed among species, sexes, and lifestages, but these differences were likely not biologically significant due to their small magnitude and the ability of wild populations of both species to adapt to high temperatures. In 24-hour tests, G. affinis displayed about twice the ammonia tolerance as did P. occidentalis. However, long-term survival in habitats with high ammonia concentrations is questionable, thus reducing the perceived benefit of using G. affinis for mosquito abatement in these habitats. Diet overlap was significant between sexes within species but was not significant between species. However, both species exhibited significant dietary selection for mosquito larvae and pupae under experimental conditions. Shared dietary preference for mosquito larvae and pupae, in addition to similarity in temperature tolerance between species, suggests that P. occidentalis, a native and historically widespread species, can be used in place of nonnative G. affinis for mosquito control. There is no evidence to suggest that nonnative G. affinis is better suited for mosquito abatement, and since G. affinis is replacing P. occidentalis throughout the native species' former range, it should no longer be introduced into the Gila River basin for mosquito control. However, managers who would use P. occidentalis for mosquito abatement must take care not to interfere with conservation efforts by disrupting the genetic structure of natural populations of P. occidentalis.
Effect of Serial Passaging on the Morphology and Biological Characteristics of Human Adipose Tissue-derived Stem Cells

Somatic stem cells posses an exclusive property of self regeneration and plasticity which makes them promising candidates for use in tissue engineering and regenerative medicine. In the case of stem cell therapy it is crucial to obtain them in sufficient amount. That's why they have to be cultured under in vitro conditions. Long term culture provides adequate number of cells, but on the other hand it is associated with increased risk of spontaneous cell transformation. In this study we analyzed the effect of serial passaging (up to 10th passage) on the morphological and selected biological characteristics of human stem cells isolated from adipose tissue in respect to potential malignant transformation. Obtained results showed that human adipose tissue-derived stem cells maintained their morphological and biological properties during 10 passages and after performing further tests mainly addressed the cytogenetic stability and expression of regulators of cell cycle, senescence and apoptosis, they should be safely used in clinical practice.
IMPACT OF VOLTAGE PHASE ANGLE CHANGES ON LOW-VOLTAGE RIDE-THROUGH PERFORMANCE OF SMALL SCALE HYDRO DG UNITS

Computer simulations of a simplified radial 132, 66 and 22 kV system including a 5 MVA hydro power unit, has been performed in order to assess the hydro unit's fault-ridethrough (FRT) capability, with special emphasis on the Critical Clearing Time (CCT) of the unit. The results show that there is a significant difference in CCT when the disturbance reflects a realistic fault in the system, i.e. a fault that reflects changes in both voltage magnitude and phase angle, compared with a disturbance for which only the change in voltage magnitude is taken into account. Since requirements regarding fault-ride-through (FRT) capability found in most of today's national grid codes are defined via a specified transient voltage vs. time disturbance profile, the paper therefore suggests that these requirements should be extended to include also corresponding phase angle vs. time disturbance profiles.

Modal decomposition of meta-atom dynamics

The modes of meta-atoms are a natural basis for describing their excitation and interaction, however many structures of practical interest are too complex to find their modes analytically. It is shown here how they can be found by solving for the singularities of an integral equation operator. These modes are used to construct simple yet highly accurate models, which are applied here to scattering problems. The proposed technique is implemented in a freely available open source code.
Bayesian Estimation and Model Selection in the Generalized Stochastic Unit Root Model

We develop Bayesian techniques for estimation and model comparison in a novel Generalized Stochastic Unit Root (GSTUR) model. This allows us to investigate the presence of a deterministic time trend in economic series, while allowing the degree of persistence to change over time. In particular the model allows for shifts from stationarity I(0) to nonstationarity I(1) or vice versa. The empirical analysis demonstrates that the GSTUR model provides new insights on the properties of some macroeconomic time series such as stock market indices, inflation and exchange rates.
Morpho-Lexical Impact on Resyllabification and Stress Assignment in Suburbanite Jordanian Arabic

The present study targets interdisciplinary linguistic effects of morpho-lexical dynamic impacts on phonological processes. Therefore, it succinctly investigates some specific aspects pertaining to two Arabic dialects, namely, Modern Standard Arabic and Suburbanite Northern Jordanian Arabic. The narrow scope of this paper is deliberately confined to fathoming the role of the nominative morpheme marker in the syllable interaction at the word boundary when such a morpheme is in effect. Because both of these dialects abide by the universal ONS-constraint, the deformity of onsetless syllables are sought to be systematically repaired with the least serious constraint violation. On the one hand, the vowel in the syncopated nominative morpheme intervenes in the former, so no epenthesis occurs; on the other hand, the latter employs epenthesis to fix such a problem. This may give deeper insight into answering the question behind MacCarthy’s (2007) assumption of the hidden generalizations that rationalize optimal variations in spoken varieties in the Levant. In addition, the researcher believes that the data and the analyses presented in this paper can catalyze curiosity of some researchers to conduct many other relevant works in more depth not only to better explore such a rich interface but also to steer such an analysis towards neurological approaches that advocate parallel distributed processing in an attempt to further attest language acquisition premises in this regard.
Poverty and Ethnicity in Asian Countries

We compare the extent and the nature of the higher prevalence of poverty among disadvantaged ethnic groups in six Asian countries using demographic surveys. We first estimate a composite wealth index as a proxy for economic status, and analyze the magnitude of the ethnic gap in absolute and relative poverty levels across six countries and different ethnicities in those countries. Then, we use regression-based counterfactual analysis for explaining these ethnic differentials in poverty. We compare the actual differential in poverty with the gap that remains after disadvantaged ethnic groups are given the distribution of characteristics of the advantaged ones (by reweighting their densities using propensity scores). Our results show that there is a substantial cross-country variability in the extension, evolution, and nature of the ethnic poverty gap, which is as high as 50 percentage points or more in some specific cases in Nepal, Pakistan, or India. The gap in the latter country increased over the analyzed period, while it was reduced in the Philippines. Our analyses indicate that factors that contribute to ethnic disadvantaged groups being poorer are the strongly persistent high inequalities in education (e.g., India, Nepal, and Pakistan), in regional development (e.g., the Philippines) and the large urban-rural gap (e.g., Pakistan).
Efficient Hybrid IP Trace Back Techniques to Mobile Distributed Denial of Service Attacks

Abstract:Today's life has been revolutionized by Internet. Future of Internet is even more promising because of emerging technologies like ubiquitous computing, context sensitive, adaptive and reconfigurable applications. Security is the most important issue concerned with Internet. Internet is exposed to threats like system diffusion, monetary fraud, theft of proprietary information, Denial of Service (DoS)/Distributed Denial of Service (DDoS) Attacks etc. The proposed system improved hybrid trace back approaches is to identify the sources of attacking traffic and path reconstruction algorithms actually reveal the identity of first router on the path. This is better approach would be to find an algorithm that reveals the identity of first router without requiring the participation of all the routers on the path. In this proposed system, we have used the real time attack and legitimate traces in order to perform the simulation of DDoS attacks. We have simulated the network topology and attach the real time traces with the topology. The impact of attack is measured in terms of metrics such as throughput and Time.
Food Industry Mergers and Acquisitions Lead to Higher Labor Productivity

Processing plants in eight major food industries were highly productive before being acquired and they significantly improved their labor productivity afterward, Economic Research Service and U.S. Census Bureau researchers found in their analysis of Census data. The plant-level data on production inputs and costs provided a detailed picture of food-production facilities involved in mergers and acquisitions. The industries are meatpacking, meat processing, poultry slaughtering and processing, cheese making, fluid milk processing, flour milling, feed processing, and oilseed crushing. The analysis suggests that mergers and acquisitions contributed to the general improvement in labor productivity, echoing an earlier ERS study. Labor productivity is defined as output per worker.
Trade liberalisation, adoption costs, and import margins in CEEC and OECD trade

Within a standard gravity framework I explore the impact of country size and trade liberalisation on extensive and intensive margins of imports across broad categories of goods. This allows testing hypotheses from two distinct strands of the trade literature, i.e., vertical integration versus trade in technology goods. First, there is evidence in favour of a unilateral complement to Yi’s (2003) claim that vertical integration magnifies the trade effect of multilateral trade liberalisation: I find a substantially stronger than average impact of unilateral trade liberalisation on imports of vertically integrated intermediate goods along both extensive and intensive margins. On the contrary, I find no evidence in favour of Romer’s (1994) hypothesis of fixed costs of technology adoption when the state of technology is operationalised as the variety of capital goods. Results are robust to the measurement of trade liberalisation, to extending the product space allowing for national product differentiation, to sample composition, and to varying the gravity framework according to Baldwin and Taglioni (2006).
Litter fauna communities and litter decomposition in a selectively logged and an unmanaged pine-oak forest in Mexico

Se analizo el efecto del manejo silvicola en la abundancia, riqueza y diversidad de la fauna de invertebrados, asi como en la tasa de descomposicion de la hojarasca en un bosque templado de pino (Pinus spp.) y encino (Quercus spp.) del centro de Mexico. Se comparo un bosque manejado (tala selectiva) y otro sin manejo, empleando un experimento de bolsas de malla plastica (litterbags). El bosque sin manejo tuvo mayor abundancia, riqueza y diversidad de morfoespecies de invertebrados que el bosque donde se aplico tala selectiva. Se encontraron diferencias significativas en la hojarasca remanente y en la tasa de descomposicion entre bosques: la hojarasca en el bosque sin manejo se descompuso mas rapidamente que en el que se aplica tala selectiva. La hojarasca remanente correlaciono de forma negativa con la riqueza de invertebrados en el bosque manejado y con la riqueza y diversidad en el bosque sin manejo. Estos resultados indican que a mayor diversidad de fauna, mas hojarasca puede descomponerse. El estudio muestra que las practicas silviculturales pueden afectar los patrones de diversidad de invertebrados del suelo y los procesos de descomposicion de los que forman parte. Se propone como medida de conservacion dejar fragmentos de bosque sin manejo en localidades donde se aplica tala selectiva para mantener la diversidad y los procesos ecosistemicos en estos bosques templados
Label-free DNA sequence detection using oligonucleotide functionalized optical fiber

The authors present a label-free method for direct detection of deoxyribonucleic acid (DNA) sequences. The capture DNA is immobilized onto the surface of a silica optical fiber tip by means of the layer-by-layer electrostatic self-assembly technique. Hybridization of target DNA with complementary capture DNA increases the optical thickness of the fiber tip. This phenomenon can be detected by demodulation of the spectrum of a Fabry-Perot cavity fabricated in the optical fiber. Experimental results demonstrate sequence specificity and sensitivity to nanogram quantities of target DNA sequences with short (∼5min) hybridization time.
Arbitrary accuracy iterative quantum phase estimation algorithm using a single ancillary qubit: A two-qubit benchmark

We discuss the implementation of an iterative quantum phase estimation algorithm with a single ancillary qubit. We suggest using this algorithm as a benchmark for multiqubit implementations. Furthermore, we describe in detail the smallest possible realization, using only two qubits, and exemplify with a superconducting circuit. We discuss the robustness of the algorithm in the presence of gate errors, and show that seven bits of precision is obtainable, even with very limited gate accuracies.
DNA markers in the authentication of Traditional Chinese Medicine

Traditional Chinese medicine (TCM), with its multi-target effects, is gaining more and more attention all over the world due to its specific theory and long historical clinical practice. But the absence of an objective and accurate inspection system is frequently cited as one of the major hurdles for its modernization and globalization. Benefiting from modern molecular biology and polymerase chain reaction (PCR) techniques, DNA markers have become one of the most reliable methods for identification and authentication of Chinese medicinal materials. This paper reviewed the recent progress of DNA markers, including PCR-based markers, hybridization-based markers, sequenced-based markers, and DNA microarray in the authentication of TCM. Key words: DNA marker, Traditional Chinese medicine (TCM), polymerase chain peaction (PCR).
