Dynamic resource allocation for elastic systems based on scalability modeling

Cloud computing is a new paradigm in which virtual resources are leased in the short-term. Cloud providers publish an API through which users can request, use, and release those resources. Thus, a properly architected system can be quickly deployed and their infrastructure can be quickly updated to better accommodate workload uctuations and limit expenses. Many services running in clouds comprise an automated resource management unit, which is in charge of requesting and releasing resources without human intervention, as demand changes. The rule based approach, commonlly applied to automate the resource management, is especially problematic in cases of load surge. When of a quick and drastic increase of the workload, the system may take many cycles of infrastructural redimensioning until achieve an adequate state. In this case, the system remains overloaded during all those cycles, a ecting user experience. In this research, we investigate how we can properly understand what are the e ects, in system capacity, incurred by variations in resource availability, and how this knowledge can be applied to improve elasticity. We propose a strategy that comprises performing scalability tests to model scalability and apply the model to estimate resource need, according to the arriving workload. We introduce a framework for automated scalability evaluation of distributed systems and experimentally evaluate the proposed strategy. We compare the allocation and performance obtained using our strategy with a rule based strategy in a trace-driven simulation and with synthetic workloads. We also evaluate six variations of the model-based approach. Generally, our approach can deliver better performance, while increasing resource allocation and, consequently, cost. The extent of the performance improvement is larger than the cost increment, though.
The Rat Uterus after U-74389G Process

Aim: This study co-evaluated the 4 quoted histologic variables after the lazaroid U-74389G (L) drug administration. The calculation was based on the results of 2 preliminary studies, each one evaluating two respective histologic variables of Endometrial Edema (EE) and Uterus Inflammation (UI) or Endometrial Karyorrhexis (EK) and Uterus Congestion (UC); in an induced ischemia reperfusion animal experiment. Materials and methods: The 2 main experimental endpoints at which the EE, UI and EK, UC scores were evaluated was the 60th reperfusion min (for the groups A and C) and the 120th reperfusion min (for the groups B and D). Specially, the groups A and B were processed without drugs, whereas the groups C and D after L administration. Results: The first preliminary study showed that L has a non-significant recessing potency for EE and UI histologic parameters at the “without lesions” grade 0.2636364±0.14594051 (p-values=0.0698). The second preliminary study showed that L has a non-significant recessing potency for EK and UC histologic parameters at the “without lesions” grade 0.1253529 ± 0.08529668 (p-values=0.1373) since they were co-evaluated together. These 2 studies were co-evaluated since they came from the same experimental setting. This study co-evaluated the combined diagnostic values of the four variables together. Conclusion: L administration and reperfusion time together non-significantly accentuated the 4 histologic variables within the “without lesions alterations” score 0.0758471 [-0.1464624 - +0.2981566] (p-value=0.4940).
Ergot toxicosis causing death in weaned beef calves

Eight bull beef calves weighing approximately 500 lb (227 kg) died following consumption of toxic levels of ergot alkaloids during the summer of 2012. Survivors demonstrated chronic effects of ergot alkaloid toxicosis, including poor growth and hyperthermia. All 60 calves on the farm had been weaned for 3 weeks at the time of the incident, and were consuming a free-choice pelleted creep feed which was identified as the source of the toxin. Two common sources of ergot alkaloid in livestock in the United States are tall fescue grass infected by the fungal endophyte Neotyphodium coenophialum, and Claviceps purpurea-associated sclerotia on seed heads of grasses or cereal grains. Toxic levels of ergot alkaloids in commercial feed as found in this case is not common.
EFFECT OF AGING ON THE SUSTAINABLE PHOTOCATALYTIC ACTIVITY OF ANATSE/RUTILE N-DOPED TIO2

Advancing photoactive metaloxides is an active area of research for enviromental application. In this study, with the special focus on the efect of aging time on physico-chemical properties, visible light active nitrogen doped titanium dioxide (N-TiO2) nano-photocatalysts were successfully synthesized by hydrolysis of titanium tetraisopropoxide in the presence of guanidium chloride via a simple solgel method. The resulting materials were subjected to different characteration techniques; Xray diffraction, ultraviolet–visible diffuse reflection spectroscopy, photo-luminescence, scanning electron microscopy, energy dispersive X-ray spectroscopy, and BET surface areas. Moreover, their photo-catalytic perfomation was evaluated against MB dye with the help of sunlight. The results revealed that the number of aging days dectates the crystal structure, morphology, light absorbation capacity, photogenerated charge carrier fate and photoactivities of the as-synthesized photocatalysts. Notably, N-TiO2 exhibited a red-shift light absorption edge to visible region and enhanced photocatalytic activity for the degradation of MB. More importantly a mon the as-prepared saomples, the mosted aged, for 9 days, N-TiO2 demostrated the best 95% MB degradation on two hours sunligh exposure. This activity mainly attributed to the higher crystal structure, anatase/rutile mixed phase, stronger light absorption sunlight, large surface and pore size, and lower photogenerated charge carrier recombination.
Effect of roflumilast on exacerbations in patients with severe COPD and a prior history of hospitalization taking combination therapy

Introduction: Roflumilast (ROF) reduces moderate and severe exacerbations in severe COPD patients at risk of exacerbation, despite ICS/LABA +/- LAMA therapy. Its effects on severe exacerbations in these patients with a history of hospitalization for COPD exacerbation have not been described. Methods: The REACT study included patients with severe COPD, chronic bronchitis, and at least two exacerbations in the previous year. ROF 500µg once daily or placebo (PBO) was added to ICS/LABA +/- LAMA for 52 weeks. In this post-hoc analysis, we used negative binomial regression to estimate severe exacerbation rates (i.e. those leading to hospitalization and/or death) in patients with or without a history of hospitalization for COPD exacerbation. Results: In the overall population (n=1935), 641 patients had a history of hospitalization for COPD exacerbation (ROF: n=322; PBO: n=319); 647 patients in each arm had no history of hospitalization. Patients with a history of hospitalization had a higher proportion of current smokers than patients with no prior hospitalization; other features were similar between groups. In patients with a history of hospitalization, ROF reduced the rate of severe exacerbations by 34.9% (ROF 0.39 vs PBO 0.60; rate ratio 0.65; 95% CI 0.48–0.89; p Conclusions: ROF reduces the rate of exacerbations leading to re-hospitalization and/or death in patients inadequately controlled with ICS/LABA +/- LAMA with a history of hospitalization for exacerbation. The reduction was higher than in patients with no prior hospitalization.
Study on the Role of Pet Animals for Helicobacter pylori Transmission

Helicobacter pylori infection is one of the most common bacterial infections in humans. Although H. pylori may be detected in the stomach of approximately half of the world's population, the mechanisms of transmission of the microorganism from person to person are not yet clear. Transmission of H. pylori could occur through, fecal-oral, and oral-oral routes, and through food and water. Helicobacter colonizes the stomachs and intestines of humans and several animal species, such as cats, dogs. Prevalence in healthy a symptomatic persons and in apparently healthy dogs and cats. H. pylori might have jumped quite recently from animal hosts to people. Because it has been possible to transfer from humans to animals it's reasonable to suppose that animals might have been the original source of the bacterium. The aim of this work is to investigate the role of pet animals in Helicobacter pylori transmission and, to study the antibiotic susceptibility of H. pylori isolate. Recent reports suggest that the overall prevalence of H. pylori in stool, saliva and, stomach juice samples of examined dogs are 41.4 %, 42.9%, and 50%, respectively. Although the incidence of H. pylori in stool, saliva, and stomach juice samples of examined cats are 30 %, 42.9% and 20 %, respectively. Moreover, we discussed the incidence of H. Pylori in stool and saliva samples of healthy persons related to dogs ware 23.9% and 8.7%, respectively, but in diseased persons ware 64.3 %and 42.9 %, respectively. Also, the incidence of H. Pylori in gastric juice samples of diseased men and women’s related to dogs with an incidence were 60 % and 66.7 %, respectively. Whole, the incidence of H. pylori in stool and saliva samples of healthy persons related to cats were 40.9 % and 45.5 %, respectively, however diseased persons were 75 % and 62.5 %, respectively. The prevalence of H. pylori in gastric juice samples of diseased men and women’s related to cats were 66.7 % and 80 %, respectively. H. pylori isolates sensitive to cefotaxime sodium, ceftazidime, ceftraxone, cefuroxime sodium, ciprofloxacin, levofloxacin, meropenem, nitrofurantion and ofloxacin. Thus,H. pylori can be isolated from feces, saliva and stomach juice of dogs, cats and human by microbiological methods without need of Endoscopy. Pet animals may be a good reservoirs for the transmission of H. pylori between domestic pets and their owners. [Mohamed Abdel-Raouf, Yousef Abdel-Gleel, Ayman Enab.

A Method for Assigning Weights to Variable Matching in Record

Introduction The Medical Expenditure Panel Survey (MEPS) is a unique, nationally representative source of micro data on health care use and expenditures for all payers. Household respondents report drugs and the number of times each drug was obtained, while a follow-back survey of pharmacies is the primary source of price and expenditure data. High quality data are critical because the MEPS is widely used for national estimates, behavioral modeling, and policy simulations, including many analyses of prescription drug markets. Ongoing efforts to ensure data quality seek to maintain the currency of the data in rapidly changing pharmaceutical markets (Hill et al. 2011). This project investigates potential improvements in the methods used to match or impute pharmacy data to the drugs reported by households, specifically for household-reported drugs for persons lacking pharmacy data. In particular, we examine a range of regression-based methods of deriving matching weights for imputing pharmacy data. Using a validation sample, we compare predictive accuracy for current and alternative matching weights.
Geometrically nonlinear flexural vibrations of plates: In-plane boundary conditions and some symmetry properties

This study is devoted to the derivation of some properties of the von Kármán equations for geometrically nonlinear models of plates, with a boundary of arbitrary shape, for applications to nonlinear vibration and buckling. An intrinsic formulation of the local partial differential equations in terms of the transverse displacement and an Airy stress function as unknowns is provided. Classical homogeneous boundary conditions—with vanishing prescribed forces and displacements—are derived in terms of the Airy stress function in the case of a boundary of arbitrary geometry. A special property of this operator, crucial for some energy-conserving numerical schemes and called ‘‘triple self-adjointness’’, is derived in the case of an edge of arbitrary shape. It is shown that this property takes a simple form for some classical boundary conditions, so that the calculations in some practical cases are also simplified. The applications of this work are either semianalytical methods of solution, using an expansion of the solution onto an eigenmode basis of the associated linear problem, or special energy-conserving numerical methods. r 2008 Published by Elsevier Ltd.
Application of EM Algorithm to Mixture Cure Model for Grouped Relative Survival Data

The interest in estimating the probability of cure has been increasing in cancer survival analysis as the cure of some cancer sites is becoming a reality. Mixture cure models have been used to model the failure time data with the existence of long-term survivors. The mixture cure model assumes that a fraction of the survivors are cured from the disease of interest. The failure time distribution for the uncured individuals (latency) can be modeled by either parametric models or a semi-parametric proportional hazards model. In the model, the probability of cure and the latency distribution are both related to the prognostic factors and patients’ characteristics. The maximum likelihood estimates (MLEs) of these parameters can be obtained using the Newton-Raphson algorithm. The EM algorithm has been proposed as a simple alternative by Larson and Dinse (1985) and Taylor (1995). in various setting for the cause-specific survival analysis. This approach is extended here to the grouped relative survival data. The methods are applied to analyze the colorectal cancer relative survival data from the Surveillance, Epidemiology, and End Results (SEER) program.
Natural Language Compression using Byte Codes

The thesis studies the properties of what has become known as Byte Codes. This is a basic problem of Coding Theory which is an important part of the larger field of Data Compression.In order to achieve some compression gain, the easy to handle fixed length codes have long ago been replaced by variable length codes, which are more difficult to handle and thus imply a processing slowdown. The Byte codes are a compromise: the codewords are still of variable length, but the lengths are restricted to multiples of byes, so the handling is faster. The thesis reviews existing By'te codes and then goes on to suggest new variants. All these codes are compared according to various criteria, showing that the new suggested ones are competitive
THE NEUROPHYSIOLOGY OF WELL-BEING. MINDFULNESS – AN UNTAPPED, INNATE WAY TO DECREASE THE EPIDEMIC OF UNWELCOME EATING BEHAVIORS NEUROFIZJOLOGIA DOBREGO SAMOPOCZUCIA. UWAŻNOŚĆ – NIEWYKORZYSTANY, WRODZONY SPOSÓB NA OGRANICZENIE EPIDEMII NIEPOŻĄDANYCH ZACHOWAŃ ŻYWIENIOWYCH

Introduction The state of stress/anxiety or of wellbeing are physiologically determined by the interaction between the two parts of autonomic nervous system: the sympathetic (SNS) and parasympathetic (PNS) nervous system. It is increasingly understood that certain somatic disorders (binge eating, obesity, cardiovascular and autoimmune diseases, fibromyalgia etc.) have a psychological exacerbating component, closely linked to SNS overstimulation. Psychological distress promotes deposition of fat, mainly in abdominal area and is associated with weight gain. It also promotes the consumption of ‘comfort foods’ which are mostly high in fat and sugar, causing further weight gain. Aim The aim of the work is to present Mindfulness as a method of coping with stress and to highlight data encouraging its use, particularly in abnormal/excess eating behaviors. Methods Mindfulness is a kind of mental discipline that may help in restoring of disrupted SNS-PNS balance. It is originating from the 2.500-year-old Buddhist contemplative practices and adapted to suit non-religious contexts, including corporations, hospitals, schools, sports teams or armies. Research into the effect of mindfulness has shown that it may mitigate stress related damage by decreasing cortisol levels, lower blood pressure, increase immune functioning and increase telomerase activity. Results and conclusions Coping methods for stress are largely neglected in most treatment regimens. There are also no medical standards in this area. Disseminating the techniques of restoring sympathetic – parasympathetic balance, like mindfulness, may contribute to decreasing of prevalence of the diseases associated with SNS overstimulation, among them the epidemic of unwelcome eating behaviour. Evidently, more longitudinal studies that examine the mindfulness efficacy for the treatment of chronic illnesses would be of great benefit. Author responsible for correspondence: Assoc.

Magnetic properties of bilayered Fe67Co18Si1B14/Co66Fe4Ni1Si15B14 amorphous alloy core

In this paper, we present the investigation of magnetic characteristics of bilayered Fe-Co amorphous alloy ring-shaped core. They were measured on the specially designed measurement stand, called the hysteresisgraph. Highly nonlinear behavior, such as double hysteresis, was observed. The obtained B(H) and μ(H) characteristics are distinctly different from the typical, single-phase ferromagnetic materials.
Problem Deficit Theory of Mind in Geriatric Patients

The analysis of foreign and own studies Theory of Mind the ability to understand the mental states of themselves and other people in elderly people. It is shown that the mental model (theory of mind) is a new paradigm of cognitive psychology, effective for the analysis of late ontogeny. This paradigm has its own specificities and differs from the paradigm of social cognition. It argued the hypothesis that the Theory of Mind is the mental mechanism of social cognition, differentiated features of these paradigms. Generalization of researches cognitive and affective components, Theory of Mind in elderly and senile age have shown that this ability did not change totally. There is heterogeneity of mental ability to understand the psychological world with a greater degree of safety emotional component. The factors that affect the efficiency of Theory of mind were extracted in elderly persons (methodological, neuroanatomical, cognitive, psychosocial). We described the development strategies Theory of mind in aging.
Detection of Yersinia enterocolitica in the Shami goat’s milk in the North Sinai Governorate

Considerable difficulties are associated with the isolation of Yersinia enterocolitica from food particularly milk and milk products. Most methods are time consuming require enrichment steps and are unable to differentiate pathogenic isolates from non pathogenic ones. The purpose of this study was to evaluate the detection of Yersinia enterocolitica in milk by both polymerase chain reaction (PCR) and conventional culturing methods. Fifty milk samples were collected from Shami goats in North Sinai governorate. Two primers (DG26 and DG63) were used in PCR and the size of the PCR-product was 440bp. The results obtained by PCR technique were in good agreement with that obtained by conventional culturing method. Five samples (10%) were positive by PCR while 4 samples were positive by conventional culturing method. Interestingly, PCR results are obtained within few hours. Moreover, it solved the problem of interpretation of classical biochemical and serological typing in one step without necessity of using additional examinations. This makes diagnosis in food control laboratories much faster and more efficient.
Evaluation of Best Management Practices in Nitrogen Management – A Study in Groundwater Nitrate Contaminated Area of Cuddalore District, Tamilnadu

In many parts of the country there is growing concern about the degradation of water quality that draws the attention of professionals involved in this field. Groundwater contamination has many sources and evidences suggest that agriculture’s relative contribution may be significant. The deleterious effects of groundwater contamination by agrochemicals particularly nitrogenous fertilizers pose serious socio economic and environment threat to many rural communities who subsist on this resource. The best way of managing the nitrate pollution is the promulgation and adoption of Best Management Practices (BMP) and this paper attempts to validate the BMP practices that will contain nitrate pollution. In the present study an attempt was made to construct BMP Index for calibrating the efficient nitrogen use. To assess the influence of the important factors that determine the adoption of Nitrogen Best Management Practices an empirical linear model was specified. The BMP attributes comparison of crops in affected block showed that among the crops, the actually applied nitrogen over the recommended dose was the highest in paddy crop, the scale on fertilizer application techniques was the lowest in sugarcane crop and the overall NBMP index was the lowest in paddy crop. In unaffected block among the crops the nitrogen application over the recommended dose, the scale on fertilizer application technique and the overall BMP index were all in unfavourable condition towards tapioca. The comparison of the two blocks reveals that among all the attributes that builds up the BMP index, the scale on fertilizer application techniques favourably contributed in the case of unaffected block. The source of technical guidance was found to be an important variable, which influenced the BMP index of both the affected and unaffected blocks to a considerable extent. Hence it was recommended to strengthen the awareness on groundwater nitrate contamination and impart technical knowledge on BMP through efficient institutional arrangements and the role of economic instruments for voluntary adoption of BMP is also suggested.
Light and electron microscopy of Paranella diplodae N. SP. (Polyopisthocotylea;Microcotylidae; Monogenea ) from some Red Sea Teleost fishes in Egypt

The present study deals with a monogenean parasite infecting, some marine fish through light and scan electron microscopy. It revealed that the percentage of infection was 48% (14 out of 50 fish), 28% (14 out of 50 fish), 22% (11 out of 50 fish) and 16% (8 out of 50 fish) in Diplodus noct, Gerres oyena, Lethrinus elongates and Siganus revulatus, respectively. The present work recorded Paranaella diplodae (Polyopisthocotylea; Microcotylidae; Monogenea) as a new species collected from the investigated fish gills. They are lanculate flukes, the haptor is not distinguished from the body proper approximately 1/3 of the whole body length. The surface topography of the parasite bears small pits and conspicuous transverse folds and richly supplied with papillae-like unicellate sensory ending. The opisthohaptor is typical of Microcotylidae. The clamp structure and the haptoral tegument are similar to the rest of the body.
