Fault Tolerance Based Load Balancing Approach for Web Resources in Cloud Environment
Authors: Shukla Anju , Kumar Shishir , Singh Harikesh
Published: February 2020

Cloud computing consists group of heterogeneous resources scattered around the world connected through the network. Since high performance computing is strongly interlinked with geographically distributed service to interact with each other in wide area network, Cloud computing makes the architecture consistent, low-cost, and well-suited with concurrent services. This paper presents a fault tolerance load balancing technique based on resource load and fault index value. The proposed technique works in two phases: resource selection and task execution. The resource selection phase selects the suitable resource for task execution. A resource with least resource load and fault index value is selected for task execution. Further task execution phase sets checkpoints at various intervals for saving the task state periodically. The checkpoints are set at various intervals based on resource fault index. When a task is executed on a resource, fault index value of selected resource is updated accordingly. This reduces the checkpoint overhead by avoiding unnecessary placements of checkpoints. The proposed model is validated on CloudSim and provides improved performance in terms of response time, makespan, throughput and checkpoint overhead in comparison to other state-of-the-art methods.

Authors: Deng Lei , Gao Yong
Published: February 2020

In this paper, authors propose an auditory feature extraction algorithm in order to improve the performance of the speaker recognition system in noisy environments. In this auditory feature extraction algorithm, the Gammachirp filter bank is adapted to simulate the auditory model of human cochlea. In addition, the following three techniques are applied: cube-root compression method, Relative Spectral Filtering Technique (RASTA), and Cepstral Mean and Variance Normalization algorithm (CMVN).Subsequently, based on the theory of Gaussian Mixes Model-Universal Background Model (GMM-UBM), the simulated experiment was conducted. The experimental results implied that speaker recognition systems with the new auditory feature has better robustness and recognition performance compared to Mel-Frequency Cepstral Coefficients(MFCC), Relative Spectral-Perceptual Linear Predictive (RASTA-PLP),Cochlear Filter Cepstral Coefficients (CFCC) and gammatone Frequency Cepstral Coefficeints (GFCC)

No Kin: Between the Reproductive Paradigm and Ideals of Community
Authors: Edenheim Sara
Published: February 2020

This article positions the sinthomosexual in relation to kinship, climate crisis, and vulnerability. By placing Lee Edelman’s version of queer in the modern family, the sinthomosexual – here presented in the form of the childfree woman – is positioned not only as against reproduction, but also against certain versions of community and kinship. The article investigate what this position is dependent on and gets subjected to in the wake of the dismantling of the welfare state and the privatisation of economies, communities and identities. This is done by a close reading of the so-called anti-social turn in relation to different feminist versions of kinship and community – from radical lesbian feminism to posthumanism. The article also gives a historical and cultural background to the position of the childfree woman.
Can Behavioral Research Improve Transplant Decision-Making? A Mock Offer Study on the Role of Kidney Procurement Biopsies
Authors: Stewart Darren , Shepard Brian , Rosendale John , McGehee Harrison , Hall Isaac , Gupta Gaurav , Reddy Kunam , Kasiske Bertram , Andreoni Kenneth , Klassen David
Published: February 2020

Background

The use of procurement biopsies for assessing kidney quality has been implicated as a driver of the nearly 20% kidney discard rate in the United States. Yet in some contexts, biopsies may boost clinical confidence, enabling acceptance of kidneys that would otherwise be discarded. We leveraged a novel organ offer simulation platform to conduct a controlled experiment isolating biopsy effects on offer acceptance decisions.

Methods

Between November 26 and December 14, 2018, 41 kidney transplant surgeons and 27 transplant nephrologists each received the same 20 hypothetical kidney offers using a crossover design with weekend “washout” periods. Mini-study 1 included four, low serum creatinine (<1.5 mg/dl) donor offers with arguably “poor” biopsy findings that were based on real offers that were accepted with successful 3-year recipient outcome. For each of the four offers, two experimental variants—no biopsy and “good” biopsy—were also sent. Mini-study 2 included four AKI offers with no biopsy, each having an offer variant with “good” biopsy findings.

Results

Among low serum creatinine donor offers, we found approximately threefold higher odds of acceptance when arguably poor biopsy findings were hidden or replaced with good biopsy findings. Among AKI donor offers, we found nearly fourfold higher odds of acceptance with good biopsy findings compared with no biopsy. Biopsy information had profound but variable effects on decision making: more participants appeared to have been influenced by biopsies to rule out, versus rule in, transplantable kidneys.

Conclusions

The current use of biopsies in the United States appears skewed toward inducing kidney discard. Several areas for improvement, including reducing variation in offer acceptance decisions and more accurate interpretation of findings, have the potential to make better use of scarce, donated organs. Offer simulation studies are a viable research tool for understanding decision making and identifying ways to improve the transplant system.
Potassium Homeostasis, Chronic Kidney Disease, and the Plant-Enriched Diets
Authors: Palmer Biff F. , Colbert Gates , Clegg Deborah J.
Published: February 2020

There are data demonstrating that ingestion of potassium-rich foods reduces the incidence of stroke, hypertension, nephrolithiasis, and osteoporosis. Dietary-consumption data indicate Westernized diets are high in processed foods, high in sodium content, and low in potassium. In fact, there are data suggesting individuals are not consuming enough potassium in their diet. Although consumption of diets high in plant proteins, fruits, and vegetables—which are excellent sources of potassium—is recognized as healthy and beneficial, individuals with decrements in their kidney function have been advised to avoid these foods. In reviewing the literature that provides the rationale for potassium restriction in patients with reductions in kidney function, it appears there is little direct evidence to support the levels of restriction which are now prescribed. Additionally, there are two new potassium-binding agents which are well tolerated and have been documented to be effective in controlling serum potassium. Therefore, with the new binding agents and the lack of empirical evidence supporting the stringent dietary potassium restrictions, the authors conclude by indicating the pressing need for further research focusing on dietary liberalization of potassium in patients with reductions in kidney function to enhance overall health and well being, to provide them cardiovascular benefits, and to reduce overall risk of mortality through the incorporation of potassium-enriched foods.

Authors:   Gazayev K.-M.M., Agoyeva E.A., Ittiev A.B.
Published: February 2020

Urgency of the issues concerning studying water quality in mountain-glacial high-mountain regions of the Caucasus where the rivers feeding the Kabardino-Balkar Republic lowland parts originate has been highlighted. The Bezengiysky Canyon river waters have been investigated for Mn, Zn, Cu, Pb, Ag, Ni, Cr, and Cd content. The high-mountain glacial/mountain fed Cherek Bezengiysky River microelements’ concentration values have been compared from the source to the mouth both during winter low-water and glacial flood periods. It has been stated that river water microelements contamination in the high-mountain region is caused by natural geochemical and geo/morphological background and is connected with the microelements washing out mountain rocks. Earlier investigations have shown that the microelements concentration significantly drops in comparison with the upper reach when the river enters the lowlands. It was found that the Cherek Bezengiysky River waters under study in terms of Mn, Pb, Cr, Cd, Ni, Cu, and Ag content could be classified as clean water excluding Zn which made the water very polluted. Minimal, maximal and average values of the main ion and nitrogen-containing substances concentrations during winter low-water and glacial flood periods have been presented. The value of the conducted investigation is determined by the fact that the Cherek Bezengiysky River inflows to the Terek River and forms the Caspian Sea river basin.

Issues concerning the correctness of the currently used system of admissible discharge norms development, as well as the practice of initial hydrological and hydro/chemical information input have been considered. Required and sufficient conditions of V.A. Frolov – I.D. Rodziller and A.V. Karaushev methods application have been substantiated. The necessity of transfer to the use of combined schemes including one-dimensional, two-dimensional and threedimensional models in calculation of the admissible discharge norms has been demonstrated. The above models enable to calculate the watercourse hydrodynamic parameters in accordance with the normal water consumption morphometry provided the hydrodynamic blocks availability. Within-year and inter-year non-stationarity of the hydrological and hydro/chemical characteristics’ rows used in development of the admissible discharge norms development has been discussed, the necessity of the minimal water consumption correction in these calculations due to climate change has been proved. Assessment of correctness of the currently adopted in the admissible discharge method heterogeneity threshold for background concentrations values both by analytic methods and by the direct statistical methods (Monte-Carlo method) has been carried out. It was proved that application of non-parametric criteria in input of hydro/chemical initial information was effective. Comparative assessment of the median and average arithmetic values use in the hydro/chemical information analyzing was conducted.

Published: February 2020

A method of short-term forecast of water inflow to Bureya reservoir on the basis of a hydrological model and meteorological forecasts has been developed in order to improve the short-term planning effectiveness. A spatial-distribute physical/mathematical model of the runoff formation was used as a hydrological model. It was calibrated and validated by data of the retrospective hydro/meteorological observations in the Bureya River basin. Statistical criteria have shown good quality of modeling and high diagnostic potential of the model. Forecast calculations on the hydrological model with the seven days advance time can be done according the forecast meteorological data received on the basis of two atmosphere circulation models. A procedure of the forecast calculations’ correction with taking into account newly received hydrological information on water inflow to the reservoir has been applied to raise the hydrological forecasts reliability. Results of our operative test of the developed method of the water inflow to Bureya reservoir short-term forecast in 2016 are given.
Biological Productivity of the Great Lakes of Russia: Comparison of Simulating Results and Field Observations
Authors:   Bulyon V.V.
Published: February 2020

Results of analysis of the mass-balance model simulating biotic energy flows in the great lakes of Russia –Ladoga, Onego and Baikal- ecosystems have been presented. Season-average biomass and annual production of prime producers, reducers and consumers including fish have been forecasted. Permissible fish catch has been assessed. The model data were compared with the field observations results. Importance of the great lakes of Russia researches with the use of the mass-balance model is stipulated by their size and value as the biggest and Europe, besides, Lake Baikal is the greatest water body of the world in terms of the fresh water stock. Determination of these lakes’ trophic status is of primary importance for water quality assessment and for prediction their total biological productivity, fish productivity and permissible fish catch. This is possible only provided application of the balance-energy approach based on the knowledge of regularities of the organic matter and energy transfer through the ecosystem trophic units. A forecast of the lakes biological productivity was composed on the basis of quantitative links between key biotic and abiotic components of an aquatic ecosystem summed up in the form of the massbalance model. Results of the model test by the empiric data have shown that it possesses sufficient prediction reliability and is applicable for development of the lacustrine ecosystems’ biotic balances. The model can serve as a good tool for reconstruction of the lacking data and expert assessment of the ecosystems’ trophic status provided the specific local conditions are taken into account. Moreover, it can be used for cross-checking of empiric and the model predicted data reliability.

Published: February 2020

The Lake Baikal history and the main problems of its regulation have been discussed. Analysis of the lake level alterations over the whole period of instrumental observations (1900–2016) has been carried out. A protracted low-water period was observed in the Baikal basin fromthe middle 90s of XX century. It was the longest for the whole period of instrumental observations. The extreme low-water situation in the lake basin in 2014–2015 has been studied. A statistically significant trend of the temperature increase and precipitations decrease has been stated. Atmospheric precipitations affect the river runoff many-year fluctuations more than other water balance elements. It was stated that the Lake Baikal level directly depends on the Selenga River water content. Minimal runoff during the low-water periods demonstrates a tendency to decrease, just like the annual runoff. It was a perpetual series of the reduced runoff that caused the minimal runoff negative trend, as a result of which the water resources inflow to the Lake Baikal was recordbreaking minimal over the previous years. The Selenga River basin runoff parameters spatial-temporal reconstruction was performed according the hydrometric posts and dendro/climatic stations data. The water runoff reconstruction statistic models show a good agreement between the Archangel fir ring amount of growth and annual water flow. The historic chronicles and moisture regimes have been chronologically compared on the basis of the obtained water regime reconstructions. The historic chronicles analysis is an indirect verification of the obtained time series related to the water flows in the Selenga River basin.
Methods of the Real-time Runoff Account under the Conditions of the Bed Silting (the Matyra River in the village of Krutoye range as a study case)
Authors:   Sharina Y. V.
Published: February 2020

This paper presents the updated method of the real-time runoff calculation in conditions of river channel silting based on the method of optimal extrapolation. The Matyra river used as the example. The results of the analysis of the data obtained by observations of the Matyra River water regime during the period from 1994 to 2013 have been presented. We have analyzed all specific features of the hydrologic regime characteristics alterations under the influence of meteorological factors over the periods of the bed silting. The proposed decisions for real-time runoff account employ basic many-year dependence of the water discharge rates on water levels that have been exactly defined by the latest measurements of the water discharge rate through introduction of corrections that characterize changing of the bed passage ability of the year under consideration. These changes are calculated by the method of optimal extrapolation of the series of relative deviations from many-year water discharge curve calculated over the year under consideration. Assessment of the statistic characteristics of the relative deviation series such as auto-correlation function, dispersion and expectation value has been done to calculate weight coefficients in the optimal extrapolation formulas. Assessment of the proposals effectiveness has been carried out on the basis of the data of realtime and regime runoff accounting over the 2008-2013 period. Root mean square deviations from the regime accounting data were 5–10 %. The obtained results enable to make a conclusion on adequate reliability of the real-time runoff accounting data obtained with the use of the developed methods and to recommend it for real-time accounting of the small and medium-sized considerably silted rivers runoff.

Published: February 2020

O presente trabalho apresenta análises acerca das políticas públicas de incentivo ao surfe no município de Salinópolis/PA, apresentando o espaço da cidade como local propício para o desenvolvimento deste esporte. A metodologia consistiu em consulta bibliográfica, pesquisa de campo realizada através de observação e perguntas semi estruturadas que destacaram as falas de nove colaboradores, sendo sete atletas presentes no ranking estadual (2017), e dois gestores de ações de incentivo ao surfe no município. Foi utilizada uma abordagem fenomenológica, de enfoque qualitativo, e o método da análise de conteúdo (BARDIN, 2011). Para compreender os aspectos desta pesquisa foram utilizados Mascarenhas, (2007); Bahia e Nascimento, (2014) no âmbito do lazer e políticas públicas, Ribeiro (2003), Knijinck e Cruz (2010) e Dias (2008) para a trajetória histórica do surfe; Santos (1996; 2015) e Brunhs (1997) para a apropriação espacial. Os resultados apontam que, apesar da visibilidade e do reconhecimento dos atletas salinopolitanos, não ocorre investimento do poder público para o surfe em Salinópolis/PA, sendo que o desenvolvimento e apoio à modalidade depende da mobilização de associações. Conclui-se que, por não haver investimento do poder público voltado para o surfe em Salinópolis/PA, mesmo o meio ambiente sendo favorável à prática desse esporte, vê-se como relevante a criação de projetos voltados ao surfe que envolvam o ambiente natural da cidade em programas de lazer e preservação ambiental.

O objetivo deste trabalho foi analisar o programa “mexa-se”, sob a perspectiva dos profissionais de educação física atuantes nos núcleos do programa, no âmbito da política pública de saúde e de lazer e suas potencialidades. O “mexa-se” é um programa criado pela Prefeitura Municipal de Sete Lagoas/MG que, por meio da prática de atividade física, objetiva promover e estimular hábitos de vida saudável ao cidadão de Sete Lagoas. Os dados foram coletados por meio de entrevista semiestruturada. A amostra foi constituída por quatro profissionais de educação física atuantes no programa. Nota-se que os profissionais entrevistados conseguem identificar o programa como sendo uma prática voltada para a saúde. No que tange ao conceito de Lazer e Política Pública de Lazer foi observado que nem todos os profissionais de educação física têm um conhecimento claro deste conceito. Não é possível avaliar o programa como sendo uma política pública de lazer, uma vez que não é a intenção da prefeitura, neste momento, fazer com que o “mexa-se” seja uma política pública de lazer, mas de saúde. No entanto, observa-se no programa um potencial para se tornar uma política de lazer.

Integrated Kerr microcombs
are emerging as a powerful tool as sources of multiple wavelength channels for
photonic RF and microwave signal processing mainly in the context of
transversal filters. They offer a compact device footprint, very high
versatility, large numbers of wavelengths, and wide Nyquist bands. Here, we
review recent progress on Kerr microcomb-based photonic RF and microwave reconfigurable
filters, based both on transversal filter methods and on RF to optical
bandwidth scaling. We compare and contrast results achieved with wide comb
spacing combs (200GHz) with more finely spaced (49GHz) microcombs. The
strong potential of optical micro-combs for RF photonics applications in terms
of functions and integrability is also discussed.

Authors: Korostylev A. A. , Logvinenko L. A.
Published: February 2020

Some morphological features and quality of Erva woolly seeds were revealed. The sizes of the seeds of the NBG’s reproduction in 2018 varied within 0.6-0.8 mm, with a mass of 1000 seeds being 0.083-0.086 g. Seeds obtained under the conditions of the Southern Coast of the Crimea are characterized by a long germination period of 22-29 days. Laboratory germination at variable temperatures amounted to 64.3%, field under the condition of surface seeding with rolling 46.7%. Seeds are half-burned according to the I.V. Borisova classification of types of seed germination belong to the second type, a subtype with slow germination and a maximum of germinated seeds in the middle of the germination period. It was established that for the germination of Erva woolly seeds, an air temperature above 20°C is necessary. The lowest seed germination rate was obtained when they were germinated at a constant temperature of 20°C. Dry heating of seeds during the day before sowing had no effect. Seeding of seeds cleared of pericarp to a depth of not more than 1.0 cm results in sparse seedlings in comparison with surface sowing. Sowing seeds with pericarp can provide optimal plant density, both in the conditions of surface sowing and with the incorporation of seeds into the soil.

A finales de los años 70 en Chile, el Colectivo Acciones de Arte[CADA] realiza una serie de acciones públicas con una estructuración estratégica del concepto, del espacio y del proceso, sumamente interesante, en un contexto de represión abierta por parte del régimen militar chileno. En este ensayo se realiza una breve revisión sobre el trabajo del colectivo, su conformación interdisciplinar y el efecto de su trabajo en el presente; para discutir y posiblemente diferenciar las nociones activismo, militancia y acción cuando son llevadas a la práctica por artistas y productores culturales. A través de dicha diferenciación se busca subrayar la relevancia del diseño interdisciplinar de la acción en un contexto específico. Frente a la potencia de la postura activista que sitúa el foco en la pronunciación del sujeto que aparece en la escena pública, la acción directa sitúa la potencia en los efectos de una acción cuyo centro o foco está en las profundidades de la imagen y la palabra.
