Fractional weighted spherical mean and maximal inequality for the weighted spherical mean and its application to singular PDE

In this paper we establish a mean value property for the functions which is satisfied to Laplace-Bessel equation. Our results involve the generalized divergence theorem and the second Green’s identities relating the bulk with the boundary of a region on which differential Bessel operators ac

Establishment and Marketing of New Oil Benchmarks in the Structure of Global Oil and Oil Products Mercantile Trade: the Russian Case

The organization of oil and oil products stock trading that requires for independent national price indicators establishment, will promote the formation of a fair prices for energy commodities, the extension of influence of the national currency on the global market and the decrease of impact of external fluctuations of global economy. In this article, the authors review the possibility of inclusion of new oil benchmarks in the structure of the global oil and oil products mercantile trade. In particular, the Russian case is the major research subject, and the assessment is made for the purpose of strengthening the country's leverage over free market prices and in the interests of the state budget and national companies. Special attention is also given to the analysis of the contemporary contract structure of the global oil market and imposed risks. The authors develop the methodological framework for oil and oil products price indicators calculation and the suggestions about the promotion and marketing of Russian oil benchmark on the international level.

The Time Structure of Hadronic Showers in highly granular Calorimeters with Tungsten and Steel Absorbers

The intrinsic time structure of hadronic showers influences the timing capability and the required integration time of hadronic calorimeters in particle physics experiments, and depends on the active medium and on the absorber of the calorimeter. With the CALICE T3B experiment, a setup of 15 small plastic scintillator tiles read out with Silicon Photomultipliers, the time structure of showers is measured on a statistical basis with high spatial and temporal resolution in sampling calorimeters with tungsten and steel absorbers. The results are compared to GEANT4 (version 9.4 patch 03) simulations with different hadronic physics models. These comparisons demonstrate the importance of using high precision treatment of low-energy neutrons for tungsten absorbers, while an overall good agreement between data and simulations for all considered models is observed for steel.Comment: 24 pages including author list, 9 figures, published in JINS

Performance of the first prototype of the CALICE scintillator strip electromagnetic calorimeter

A first prototype of a scintillator strip-based electromagnetic calorimeter was built, consisting of 26 layers of tungsten absorber plates interleaved with planes of 45x10x3 mm3 plastic scintillator strips. Data were collected using a positron test beam at DESY with momenta between 1 and 6 GeV/c. The prototype's performance is presented in terms of the linearity and resolution of the energy measurement. These results represent an important milestone in the development of highly granular calorimeters using scintillator strip technology. This technology is being developed for a future linear collider experiment, aiming at the precise measurement of jet energies using particle flow techniques

Дилатация легочного аутографта и ее факторы риска после классической процедуры Росса: ретроспективное одноцентровое исследование

   Introduction. Aortic valve replacement with pulmonary autograft (Ross procedure) demonstrated excellent immediate and long-term results. Dilation of the pulmonary autograft in the long-term period is the main reason for repeated surgery. Aim: to study the prevalence of pulmonary autograft dilatation and its risk factors.   Materials and methods. From April 2009 to December 2022, 158 patients underwent classical Ross surgery. Inclusion criteria: patients aged 18 and older, patients who underwent classical surgery. Exclusion criteria: patients under 18, modifi ed methods of Ross procedure. Follow-up period: 104 (49–124) months.   Results and discussion. The median age of patients was 33 (25–43) years. Hospital mortality accounted for 0.6 %. Perioperative myocardial injury was 3.8 %, conduction disorder requiring permanent pacemaker implantation accounted for 1.9 %, the incidence of strokes and acute kidney injury requiring hemodialysis was 0.6 %. Ten-year freedom from autograft reoperation was 88.4. Ten-year freedom from reoperation for aortic aneurysm accounted for 92 %. Predictors of autograft dilatation in the long-term period were: age (OR: 0.942; 95% CI: 0.901–0.984, p = 0.008) and the initial size of sinuses of Valsalva (OR: 1.18; 95% CI: 1.027–1.215, p = 0.01).   Conclusion. Ten-year freedom from autograft reoperation due to aortic dilatation and freedom from aortic dilatation ≥ 45 mm was 92 % and 37.2 %, respectively. The main predictors of autograft dilatation in the postoperative period are the age and the initial diameter of the sinuses of Valsalva.   Введение. Протезирование аортального клапана (АК) легочным аутографтом (операция Росса) продемонстрировала отличные непосредственные и отдаленные результаты. Дилатация легочного аутографта в отдаленном периоде является основной причиной повторной операции.   Цель: изучить распространенность дилатации легочного аутографта и изучить факторы ее риска.   Материалы и методы. В период с апреля 2009 по декабрь 2022 гг. 158 больным выполнена операция Росса классическим способом. Критерии включения в исследования: возраст больных 18 лет и старше; больные, кому была выполнена операция классическим способом. Критерии исключения: пациенты моложе 18 лет, модифицированные методики операции Росса. Период наблюдения 104 (49–124) месяца.   Результаты и обсуждение. Медиана возраста больных составила 33 (25–43) года. Госпитальная летальность — 0,6 %. Периоперационное повреждение миокарда — 3,8 %. Нарушение проводимости, потребовавшее имплантации постоянного ЭКС, — 1,9 %, частота инсультов и острого почечного повреждения, потребовавшего гемодиализа, — 0,6 %. Десятилетняя свобода от реоперации на аутографте — 88,4. Десятилетняя свобода от реоперации по поводу аневризмы аорты — 92 %. Предикторами развития дилатации аутографта в отдаленном периоде стали: возраст (ОШ 0,942; 95 % ДИ 0,901–0,984, р = 0,008) и изначальный размер синусов Вальсальвы (ОШ 1,18; 95 % ДИ 1,027–1,215, р = 0,01).   Заключение. Десятилетняя свобода от реоперации на аутографте в связи с дилатацией аорты и свобода от дилатации аорты ≥ 45 мм составили 92 и 37,2 % соответственно. Главными предикторами развития дилатации аутографта в послеоперационном периоде являются изначальный диаметр синусов Вальсальвы и возраст

DEAP-3600 Dark Matter Search

The DEAP-3600 experiment is located 2 km underground at SNOLAB, in Sudbury, Ontario. It is a single-phase detector that searches for dark matter particle interactions within a 1000-kg fiducial mass target of liquid argon. A first generation prototype detector (DEAP-1) with a 7-kg liquid argon target mass demonstrated a high level of pulse-shape discrimination (PSD) for reducing $\beta$/$\gamma$ backgrounds and helped to develop low radioactivity techniques to mitigate surface-related $\alpha$ backgrounds. Construction of the DEAP-3600 detector is nearly complete and commissioning is starting in 2014. The target sensitivity to spin-independent scattering of Weakly Interacting Massive Particles (WIMPs) on nucleons of 10$^{-46}$ cm$^2$ will allow one order of magnitude improvement in sensitivity over current searches at 100 GeV WIMP mass. This paper presents an overview and status of the DEAP-3600 project and discusses plans for a future multi-tonne experiment, DEAP-50T.Comment: International Conference on High Energy Physics (ICHEP 2014), Valencia, 201
