Linear rr-Matrix Algebra for Systems Separable\\ in Parabolic Coordinates

We consider a hierarchy of many particle systems on the line with polynomial potentials separable in parabolic coordinates. Using the Lax representation, written in terms of $2\times 2$ matrices for the whole hierarchy, we construct the associated linear $r$-matrix algebra with the $r$-matrix dependent on the dynamical variables. A dynamical Yang-Baxter equation is discussed.Comment: 10 pages, LaTeX. Submitted to Phys.Lett.

Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.The first search at the LHC for the extinction of QCD jet production is presented, using data collected with the CMS detector corresponding to an integrated luminosity of 10.7  fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale

Searches for electroweak neutralino and chargino production in channels with Higgs, Z, and W bosons in pp collisions at 8 TeV

Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, and W bosons and undetected lightest SUSY particles (LSPs). The data sample corresponds to an integrated luminosity of about 19.5 fb(-1) of proton-proton collisions at a center-of-mass energy of 8 TeV collected in 2012 with the CMS detector at the LHC. The main emphasis is neutralino pair production in which each neutralino decays either to a Higgs boson (h) and an LSP or to a Z boson and an LSP, leading to hh, hZ, and ZZ states with missing transverse energy (E-T(miss)). A second aspect is chargino-neutralino pair production, leading to hW states with E-T(miss). The decays of a Higgs boson to a bottom-quark pair, to a photon pair, and to final states with leptons are considered in conjunction with hadronic and leptonic decay modes of the Z and W bosons. No evidence is found for supersymmetric particles, and 95% confidence level upper limits are evaluated for the respective pair production cross sections and for neutralino and chargino mass values

The Russian aviation in the first world war: The features of artillery fire correction

The article discusses the regulations and combat use of the Russian aviation during the First World War. The attention is paid to the implementation of the exploration and correction of artillery fire from the airplane. The authors have selected as sources the documents of the Central state historical archive of Georgia, in which there are reflected the materials governing the use of airplanes on the fronts of the First World War. The authors used the general scientific methods (analysis, synthesis, concretization, generalization), as well as the traditional methods of historical analysis. The authors used the historical-situational method, which involves the study of historical facts in the context of the studied era in conjunction with the "neighboring" events and facts. At the conclusion of the study, it should be noted that the use of aircraft has passed a long way of development during the First World War. There were expanded the spectra of the use of aircraft in war, from intelligence and reconnaissance and adjustment to using the airplanes as fighters and bombers. The change of the functional responsibilities required the establishment of clear and implemented quickly regulations in a combat situation, and such instructions governing the actions of the crew were created during the war

The personnel of the Russian army in the caucasus in 1830-1840-ies

The article presents the personnel structure of the Russian army in the Caucasus in the period of 1830-1840-ies. The attention is paid to the problems of recruitment, and the study of everyday service of soldiers and officers. There are used the materials of the regional and local archives, namely the State archive of the Krasnodar Krai and the Archival department of administration of Sochi city (Russian Federation), as well as sources of a personal origin (memoirs). The work is widely used the pre-revolutionary, Soviet and modern russian literature. The study methods are the principles of objectivity, historicism, systematic, integrated consideration of socio-subjective in the subject of study. In conclusion, the authors note that despite of the difficulties of manning the army units in the Caucasus (the flight of the soldiers, crimes, etc.) the military situation and competent management of units, and equally significant terms of service allowed to melt antisocial composition of the number of recruits into combat-ready joint. Russian officers played a significant role in the training and re-recruiting of the masses. © 2016 by Sochi State University
