Homogenization of Variational Inequalities for the p-Laplace Operator in Perforated Media Along Manifolds

We address homogenization problems of variational inequalities for the p-Laplace operator in a domain of Rn (n ? 3, p ? [2, n)) periodically perforated by balls of radius O(??) where ? > 1 and ? is the size of the period. The perforations are distributed along a (n ? 1)-dimensional manifold ? , and we impose constraints for solutions and their fluxes (associated with the p-Laplacian) on the boundary of the perforations. These constraints imply that the solution is positive and that the flux is bounded from above by a negative, nonlinear monotonic function of the solution multiplied by a parameter ? ?? , ? ? R and ? is a small parameter that we shall make to go to zero. We analyze different relations between the parameters p, n, ?, ? and ?, and obtain homogenized problems which are completely new in the literature even for the case p = 2.This work has been partially supported by the Spanish grant MINECO:MTM2013-44883-P

The LBNO long-baseline oscillation sensitivities with two conventional neutrino beams at different baselines

The proposed Long Baseline Neutrino Observatory (LBNO) initially consists of $\sim 20$ kton liquid double phase TPC complemented by a magnetised iron calorimeter, to be installed at the Pyh\"asalmi mine, at a distance of 2300 km from CERN. The conventional neutrino beam is produced by 400 GeV protons accelerated at the SPS accelerator delivering 700 kW of power. The long baseline provides a unique opportunity to study neutrino flavour oscillations over their 1st and 2nd oscillation maxima exploring the $L/E$ behaviour, and distinguishing effects arising from $\delta_{CP}$ and matter. In this paper we show how this comprehensive physics case can be further enhanced and complemented if a neutrino beam produced at the Protvino IHEP accelerator complex, at a distance of 1160 km, and with modest power of 450 kW is aimed towards the same far detectors. We show that the coupling of two independent sub-MW conventional neutrino and antineutrino beams at different baselines from CERN and Protvino will allow to measure CP violation in the leptonic sector at a confidence level of at least $3\sigma$ for 50\% of the true values of $\delta_{CP}$ with a 20 kton detector. With a far detector of 70 kton, the combination allows a $3\sigma$ sensitivity for 75\% of the true values of $\delta_{CP}$ after 10 years of running. Running two independent neutrino beams, each at a power below 1 MW, is more within today's state of the art than the long-term operation of a new single high-energy multi-MW facility, which has several technical challenges and will likely require a learning curve.Comment: 21 pages, 12 figure

Analysis of Crimean Hemorrhagic Fever Morbidity Rates in the Russian Federation in 2017 and Prognosis for 2018

This paper presents the analysis of Crimean hemorrhagic fever (CHF) morbidity rates in Russia in 2017; summarized are the results of epidemiological survey of the territory of the natural CHF focus in the south of the European part of Russia, discussed are the results of genetic typing of CCHF virus isolates. In 2017, the Russian Federation reported 78 cases of CHF. Decrease in the incidence of CHF occurred in the Volgograd Region, Stavropol Territory, Astrakhan Region, Republic of Kalmykia, and Rostov Region. For the first time since 1967, CHF case has been identified in Crimea Republic. It is expected that the level of epizootic activity of CHF natural focus in Russia in 2018 will be at least equal to 2017. In case of favorable for Ixodidae ticks weather and climate conditions of the winter 2017–2018, as well as untimely acaricidal treatments, the number of Ixodidae ticks may increase, which along with the high scale of CCHF virus infection in ticks, will contribute to the increase in CHF incidence

First Beam Commissioning of the 400 MHz LHC RF System

Hardware commissioning of the LHC RF system was successfully completed in time for first beams in LHC in September 2008. All cavities ware conditioned to nominal field, power systems tested and all Low level synchronization systems, cavity controllers and beam control electronics were tested and calibrated. Beam was successfully captured in ring 2, cavities phased, and a number of initial measurements made. These results are presented and tests and preparation for colliding beams in 2009 are outlined

Analysis of Epidemiological Situation on Crimean Hemorrhagic Fever in the Russian Federation in 2013 and Prognosis for 2014

Crimean hemorrhagic fever remains one of the priority infections in the South of Russia. Within the past five years morbidity rates are retained consistently high in a number of regions; mortality rates are on average 4.4 %. In 2013 registered were 79 cases of CHF in the Southern and North-Caucasian Federal Districts. Therewith performed has been analysis of epidemiological situation on CHF in the Russian Federation for 2013, summarized have been the results of epizootiological surveillance of the natural CHF focus area in the South of European Russia, discussed are the results of genetic CCHF virus typing, identified in 2011-2013 in the South of Russia. Based on epizootiological surveillance data made has been the forecast of epidemiological situation development as regards CHF for 2014

Crimean-Congo Hemorrhagic Fever: Epidemiological and Epizootiological Situation in the Russian Federation in 2022, Incidence Forecast for 2023

The review presents an analysis of the epidemiological and epizootiological situation on Crimean-Congo hemorrhagic fever (CCHF) in the Russian Federation in 2022. The incidence rate of CCHF registered in 2022 (59 cases) was 1.2 times higher as compared to 2021, however, below the long-term average annual values. The mortality rate was 10.2 %, which exceeds the indicators of long-term observations (in 2012–2021 – 3.2 %). Following epizootiological survey of stationary observation points, it was found that the number of Hyalomma marginatum imago in 2022, in general, corresponded to the average long-term indicators. CCHF virus isolates circulating in Russia in 2017–2022 belonged to the genetic lines “Europe-1” (V), “Europe-2” (VI), and “Europe-3” (VII). The ratio of CCHF virus genovariants in the population on the territory of the Russian Federation in 2017–2022 didn’t change. Based on the analysis of naturalclimatic factors, the forecast for the incidence of CCHF in the Russian Federation for 2023 has been made

Epidemiological Situation on Crimean-Congo Hemorrhagic Fever in the Russian Federation in 2019 and Forecast for 2020

The review presents an analysis of epidemic and epizootic situation of Crimean-Congo hemorrhagic fever in the Russian Federation in 2010–2019, summarizes the results of epizootiological monitoring of the CCHF natural focus territory in the south of European part of Russia. An unfavorable epidemiological situation regarding CCHF is maintained in the Russian Federation. In 2010–2019, 999 CCHF cases were registered in nine regions of Southern and North-Caucasian Federal Districts. In 2019, an increase in the CCHF incidence level in the entities of the SFD and NCFD was observed as compared to 2017–2018. The expansion of the territory with registered epidemic manifestations of CCHF continues. In 2010–2019, the number of imago and pre-imaginal phases of Hyalomma marginatum – the main vector of the CCHF virus in Russia, remained consistently high. High numbers of H. marginatum ticks and their CCHFV infection rates can contribute to the development of an unfavorable epidemiological situation in the south of the Russian Federation with a possible increase in the CCHF incidence in 2020
