WUXI, China, May 6, 2017 /PRNewswire/ -- The final round of the 2017 ASC Student Supercomputer Challenge (ASC17) ended in Wuxi. Tsinghua University stood out from 20 teams from around the world after a fierce one-week competition, becoming grand champion and winning the prize. As the world's largest supercomputing competition, ASC17 received applications from 230 universities around the world, 20 of which got through to the final round held this week at the National Supercomputing Center in Wuxi after the qualifying rounds. During the final round, the university student teams were required to independently design a supercomputing system under the precondition of a limited 3000W power consumption. They also had to operate and optimize standard international benchmark tests and a variety of cutting-edge scientific and engineering applications including AI-based transport prediction, genetic assembly, and material science. Moreover, they were required to complete high-resolution maritime simulation on the world's fastest supercomputer, "Sunway TaihuLight". The grand champion, team Tsinghua University, completed deep parallel optimization of the high-resolution maritime data simulation mode MASNUM on TaihuLight, expanding the original program up to 10,000 cores and speeding up the program by 392 times.

By using of a method of special series a class of solutions with a functional arbitrariness is constructed for equations of evolution type. The coefficients of the series are constructed in explicit form as a sequence of solutions of first order linear ordinary differential equations. Convergence of the constructed series is proved in a semi-infinite region, and the functional arbitrariness included in the constructed solution allows to use these series to prove solvability of initial-boundary value problems. © 2015 AIP Publishing LLC.

In the framework of the Wills-Harrison (WH) model the correction due to the non-diagonal coupling between d electrons in different atoms is suggested. Effect of this correction on the WH effective pair interaction is studied for liquid Fe, Co, and Ni. It is found that our approach gives a shift of the WH pair potential to the right-hand side for all metals under consideration (in most degree for Fe and in less degree for Ni). As a rule, such tendency leads to significant changes in calculating thermodynamic properties.

An unusual orbital state was recently proposed to explain the magnetic and transport properties of Ba3CoRu2O9. We show that this state contradicts the first Hund's rule and does not realize in the system under consideration because of a too small crystal-field splitting in the t2g shell. A strong suppression of the local magnetic moment in Ba3CoRu2O9 is attributed to a strong hybridization between the Ru 4d and O 2p states. © 2013 American Physical Society.

This paper deals with a theoretical study of the effect of chain-like heterogeneous structures on the type of deformation of ferrogel under an applied magnetic field. The analysis shows that depending on the energy of magnetic interaction between the particles, these chains can stimulate either elongation or contraction of the sample along the field. © The Royal Society of Chemistry 2013.

The paper deals with theoretical study of deformation of a ferrogel sample under the action of an applied magnetic field. The main goal of this work is to determine the type of deformation - either elongation or contraction in the field direction. To answer this question and to avoid artificial conclusions, we have estimated the free energy of the deformed sample by using standard methods of statistical physics. The analysis shows that the type of magnetically induced deformation significantly depends on initial shape of the sample, the applied magnetic field, as well as on the concentration and magnetic properties of the magnetic particles embedded in the gel. © 2012 The Royal Society of Chemistry.

A large body of experimental data points toward a charge-transfer (CT) instability of parent insulating cuprates to be their unique property. It is argued that the true CT gap in these compounds is as small as 0.4-0.5 eV rather than 1.5-2.0 eV as usually derived from the optical gap measurements. In fact we deal with a competition of the conventional (3d9) ground state and a CT state with the formation of electron-hole dimers which evolves under doping to an unconventional bosonic system. My conjecture does provide an unified standpoint on the main experimental findings for parent cuprates including linear and nonlinear optical, Raman, photoemission, photoabsorption, and transport properties related with the CT excitations. In addition I suggest a scenario for the evolution of the CuO2 planes in the CT unstable cuprates under nonisovalent doping. © 2011 American Physical Society.

Many accounts of mega-events emphasize their ability to facilitate the accumulation of capital and place them in the framework of urban entrepreneurialism. This paper examines the ways mega-events—with the help of capitalist boosterism rhetoric—become intertwined in regional and urban policies. Using the run-ups to the Shanghai Cooperation Organisation and the Brazil, Russia, India, China, and South Africa summits as case studies (Ekaterinburg in 2009 and Ufa in 2015), I investigate local citizens’ and stakeholders’ perceptions of federal and local governmental action surrounding mega-events in Russia. Drawing on the theoretical notion of clientelism, I argue that the hidden rationality in the preparation for mega-events consists of their use by local stakeholders (1) as a legitimizing tool for raising their political and economic capital and (2) as a convenient pretext to directly and indirectly elicit benefits and amplify existing practices of rent seeking. Planners evoke neoliberal rhetorics of growth and profit-oriented investments to justify the “conversations” that various ranks of elite have among themselves. The run-up to a summit is part of a strategy by regional and municipal leaders to win the President’s favour by engaging in prestigious international events. © The Author(s) 2013

The work deals with the theoretical study of ferrogel/ferroelastomer deformations under the action of a homogeneous magnetic field. The compositions with linearly magnetizable non-Brownian particles are considered. Under the field action the ferrogel/ferroelastomer samples can either elongate or contract in the field direction. The type of deformation is determined by the sample shape and microstructure of the particles' spatial disposition. Two kinds of systems are studied. The first one is the composition with the particles homogeneously distributed, like in an ideal gas, in the polymer matrix. The second kind is the system of linear chain-like aggregates of densely situated particles. The results show that the particles' spatial disposition in the matrix is crucially important for the type of macroscopical deformation of the magnetopolymer compositions. The systems with the gas-like distribution of particles, depending on the sample shape, can either elongate or contract, whereas the chains stimulate the sample elongation. © 2013 Elsevier B.V.
