Specific heat and magnetocaloric effect in Pr1-xAgxMnO3 manganites

The magnetocaloric effect in alternating magnetic fields has been investigated in Pr1-xAgxMnO3 manganites with x=0.05-0.25. The stepwise reversal of the sign of the magnetocaloric effect has been revealed in a weakly doped sample (x=0.05) at low temperatures (~80 K). This reversal is attributed to the coexistence of the ferromagnetic and canted antiferromagnetic phases with different critical temperatures.Comment: 4 pages, 4 figure

Identity and integration of Russian speakers in the Baltic states: a framework for analysis

Following a review of current scholarship on identity and integration patterns of Russian speakers in the Baltic states, this article proposes an analytical framework to help understand current trends. Rogers Brubaker's widely employed triadic nexus is expanded to demonstrate why a form of Russian-speaking identity has been emerging, but has failed to become fully consolidated, and why significant integration has occurred structurally but not identificationally. By enumerating the subfields of political, economic, and cultural ‘stances’ and ‘representations’ the model helps to understand the complicated integration processes of minority groups that possess complex relationships with ‘external homelands’, ‘nationalizing states’ and ‘international organizations’. Ultimately, it is argued that socio-economic factors largely reduce the capacity for a consolidated identity; political factors have a moderate tendency to reduce this capacity, whereas cultural factors generally increase the potential for a consolidated group identity

Capacity of second spillway of Boguchanskaya HPP

The main problem in designing the discharge of water flow from the upstream to the downstream is to ensure the capacity of spillway structures. This article discusses the design options for the design top of the spillway: with water diversion through a short nozzle in the pressure mode and energy dissipation in stilling basin, with the pressure-free and pressure-free passage of water through spillway No. 2 and damping of the flow energy by jet discharge into the lower stream by the inclined face of the threshold in the stilling basin; with no pressure passage and pressure passage of water through spillway No 2 and energy dissipation of the flow by throwing the flow discharge into the downstream by the inclined face of the threshold of a stilling basin; with the passage of building expenses through the sill in no pressure and pressure-type short-nozzle modes, with the spillway No. 2’s horizontal water outlet at the level of 139.5 m, with a jet discharge by a toe-springboard at an angle of 35°, and with the outlet rib's mark of 143.8 m. This article aims to obtain the flow characteristics of the considered spillway option for the period of temporary operation of the hydrotechnical complex

Поведенческая идентификация программ

The algorithm of pattern mining from sequences of system calls is described. Patterns are used for process identification or establishing the fact that some sequence of system calls was produced by the process which was used in pattern extraction. Existing algorithms are computationaly more complex or reveals high false positive runs in experiments in comparision with an automaton building algorithm. Our algorithm is less complex and more precise in comparision with the classical N-gram algorithm. Performance tests reveal that our kernel monitor does not significatly slow down the processing of the operating system. After 20 minutes of learning the algorithm is able to identify any thread of any process with 85% precision. Program identification based on behavior is used for anomaly detection of malicious activities in system.В работе описан алгоритм выделения шаблонов переменной длины из последовательностей системных вызовов. Эти шаблоны используются для идентификации процессов – установления того, что некоторая последовательность вызовов была сгенерирована тем же самым процессом, из которого были выделены шаблоны. Существующие алгоритмы либо вычислительно сложны, либо имеют высокий уровень ложных срабатываний по сравнению со сложным и ненадежным автоматным подходом. Предложенный в работе алгоритм имеет низкую вычислительную сложность и большую точность, чем классический N-граммный алгоритм. Тесты производительности показали, что реализованный монитор системных вызовов несущественно замедляет работу операционной системы. Предложенный алгоритм после двадцатиминутного обучения способен идентифицировать за одну минуту потоки процессов с точностью 85%. Поведенческая идентификация потоков программ используется для аномального обнаружения вредоносных воздействий на систему

BARIATRIC SURGERIES AND CORRECTION OF METABOLIC DISORDERS IN PATIENTS WITH MORBID OBESITY

The article presents the results of bariatric surgeries carried out in the clinic in patients with morbid obesity. We traced both the nearest and remote results after treatment, the loss of body weight in dynamics, relief of the manifestations of "metabolic syndrome" as well as we estimated the quality of life of patients in pre-and postoperative period

Measurement of Semileptonic Branching Fractions of B Mesons to Narrow D** States

Using the data accumulated in 2002-2004 with the DO detector in proton-antiproton collisions at the Fermilab Tevatron collider with centre-of-mass energy 1.96 TeV, the branching fractions of the decays B -> \bar{D}_1^0(2420) \mu^+ \nu_\mu X and B -> \bar{D}_2^{*0}(2460) \mu^+ \nu_\mu X and their ratio have been measured: BR(\bar{b}->B) \cdot BR(B-> \bar{D}_1^0 \mu^+ \nu_\mu X) \cdot BR(\bar{D}_1^0 -> D*- pi+) = (0.087+-0.007(stat)+-0.014(syst))%; BR(\bar{b}->B)\cdot BR(B->D_2^{*0} \mu^+ \nu_\mu X) \cdot BR(\bar{D}_2^{*0} -> D*- \pi^+) = (0.035+-0.007(stat)+-0.008(syst))%; and (BR(B -> \bar{D}_2^{*0} \mu^+ \nu_\mu X)BR(D2*0->D*- pi+)) / (BR(B -> \bar{D}_1^{0} \mu^+ \nu_\mu X)\cdot BR(\bar{D}_1^{0}->D*- \pi^+)) = 0.39+-0.09(stat)+-0.12(syst), where the charge conjugated states are always implied.Comment: submitted to Phys.
