Evolution of local computing time in parallel modeling of mobile networks

Introduction: The study concerns the properties of a parallel discrete-event simulation (PDES) model, namely a simple mobile network model known as a personal communication service (PCS) model. In this type of parallel computing, each process has its own computation time, known as local virtual time. The local virtual times change during the simulation process, forming a complex profile similar to the surface growth profile in physics.Methods: We apply the scaling theory of statistical physics to study the properties of the PCS model. We construct a simple local virtual time evolution algorithm for the PCS model and compare this theoretical time evolution model to a standard parallel mobile network implementation in Rensselaer’s Optimistic Simulation System (ROSS).Results: We show that the value of the critical exponent for the mobile network system is close to the value in the theoretical local virtual time profile model. A roughening transition is found in the LVT–PCS model, which belongs to the universality class of directed percolation in dimension 2 + 1.Discussion: We believe that the analogies we found can be useful for preliminary analyses of scalability, process desynchronization, and possible deadlocks in a wide class of parallel discrete-event simulation models

Development Of Recipes And Estimation Of Raw Material For Production Of Wheat Bread

The study of technological parameters of Midas wheat flour and possibility to use little-spread plants at wheat bread manufacturing was realized. Parameters and regimes for keeping and baking bread of new recipes were elaborated and selected. The elaborated method of bread manufacturing by new recipes relates to the field of agriculture and food industry and may be used at a laboratory baking of bread.There was experimentally grounded and introduced the change of a part of recipe quantity of wheat flour for dried and comminuted plants of Népeta mussinii L., Polymnia osotolysta L., Amaranthus tricolor L., Cosmos sulphureus L., Tanacetum parthenium L., Cyperus esculentus L., Physalis tomentous L. at baking bread. According to determined physical-chemical, organoleptic parameters of bread, a possibility of baking bread using plants was proved. The expedience of introducing vegetable additives of Népeta mussinii L., Polymnia osotolysta L., Amaranthus tricolor L., Tanacetum parthenium into wheat dough in the dose no more than 5 % to the flour mass; up to 10 % – Cosmos sulphureus L and up to 15 % – Cyperus esculentus L., Physalis tomentous L was proved. At these very dosages bread had an evenly colored crust, without breaks and cracks, elastic crumb, thin-walled porosity, expressed bread taste and pleasant smell of additives as opposite to other experimental samples

Рівень протеїну S100b у сироватці крові хворих з ко-інфекцією ВІЛ /туберкульоз як нейроспецифічний біомаркер ятрогенної нейротоксичності

There was studied the influence of antiretroviral and antimycobacterial chemotherapy on releasing from the gliacell marker lesions – S100b protein in the context of possible iatrogenic. It was established that a slight increase inthe concentration of S100b protein in blood serum of patients with co-infection of HIV /TB after starting HAART wasnot associated with the occurrence of symptoms of the central nervous system.Было изучено влияние препаратов антиретровирусной и антимикобактериальной химиотерапии навысвобождение из клеток нейроглии маркера поражения протеина S100b, в разрезе возможной ятрогении.Установлено, что незначительное повышение концентрации белка S100b в сыворотке крови больныхc ко-инфекцией ВИЧ/туберкулез после начала высокоактивной антиретровирусной терапии не былосвязано с возникновением симптомов со стороны центральной нервной системы.Вивчено вплив препаратів антиретровірусної та антимікобактеріальної хіміотерапії на вивільненняз клітин нейроглії маркера ураження протеїну S100b з огляду на можливу ятрогенію. Встановлено, щонезначне підвищення концентрації білка S100b у сироватці крові хворих з ко-інфекцією ВІЛ/туберкульозпісля початку високоактивної антиретровірусної терапії не було пов’язане з виникненням симптомів збоку центральної нервової системи

A Tri-National program for estimating the link between snow resources and hydrological droughts

To evaluate how summer low flows and droughts are affected by the winter snowpack, a Tri-National effort will analyse data from three catchments: Alpbach (Prealps, central Switzerland), Gudjaretis-Tskali (Little Caucasus, central Georgia), and Kamenice (Jizera Mountains, northern Czech Republic). Two GIS-based rainfall-runoff models will simulate over 10 years of runoff in streams based on rain and snowfall measurements, and further meteorological variables. The models use information on the geographical settings of the catchments together with knowledge of the hydrological processes of runoff generation from rainfall, looking particularly at the relationship between spring snowmelt and summer droughts. These processes include snow accumulation and melt, evapotranspiration, groundwater recharge in spring that contributes to (the) summer runoff, and will be studied by means of the environmental isotopes 18O and 2H. Knowledge about the isotopic composition of the different water sources will allow to identify the flow paths and estimate the residence time of snow meltwater in the subsurface and its contribution to the stream. The application of the models in different nested or neighbouring catchments will explore their potential for further development and allow a better early prediction of low-flow periods in various mountainous zones across Europe. The paper presents the planned activities including a first analysis of already available dataset of environmental isotopes, discharge, snow water equivalent and modelling experiments of the (already) available datasets

CLINICAL AND IMMUNOLOGICAL EFFECTIVENESS OF TREATMENT OF RAGWEED POLLINOSIS IN THE SAMARA REGION

Allergic rhinitis and bronchial asthma are widespread respiratory allergic diseases. In some territories of the Russian Federation, the dominant cause of pollinosis is ragweed. The aim of the study was to evaluate the clinical and immunological efficacy of ASIT with the allergen Ambrosia artemisiifolia in patients sensitized to Ambrosia trifida in the Samara region. Patients with proven sensitization to Ambrosia trifida was held immunotherapy with Ambrosia artemisiifolia allergoid preseason. After treatment, patients had a decrease in the severity of symptoms of allergic rhinitis according to VAS (p = 0.00001), a decrease in the need for medications (p = 0.0003), as well as the need for corticosteroids against the background of therapy from 34.6% to 0% (p = 0.00001). In 8% of cases, the result of treatment was good, in 69% satisfactory, in 23% unsatisfactory. In the control group, there were no changes in the severity of symptoms (p = 0.858). Also, in the control group, the need for medications remained unchanged and 14.3% of patients continued to use corticosteroids.After ASIT, there was a decrease in the level of IL-4 (p = 0.002), and a decrease in the ratio of IL-4/ IL-10 (p = 0.0063); at the same time, changes in the level of other cytokines (IL-10; IFNγ) were statistically insignificant (p > 0.05). Before treatment, the levels of IL-4/ IL-10 in both groups were comparable, and after treatment, the differences became statistically significant (p = 0.031). We did not get a statistically significant change in the level of IgG4 Amb a 1 or IgG4 Amb trifida. There was no correlation between the level of individual cytokines and the results of treatment. As a result of the conducted ASIT, positive clinical and immunological results were obtained. In most patients, the disease has acquired a controlled course. At the same time, the lack of excellent and low number of good results of ASIT is probably due to the intraspecific allergenic properties of ragweed
