Boundary states, matrix factorisations and correlation functions for the E-models
The open string spectra of the B-type D-branes of the N=2 E-models are
calculated. Using these results we match the boundary states to the matrix
factorisations of the corresponding Landau-Ginzburg models. The identification
allows us to calculate specific terms in the effective brane superpotential of
E_6 using conformal field theory methods, thereby enabling us to test results
recently obtained in this context.Comment: 20 pages, no figure
Patient-specific computational modeling of subendothelial LDL accumulation in a stenosed right coronary artery: effect of hemodynamic and biological factors
Patient-specific computational modeling of subendothelial LDL accumulation in a stenosed right coronary artery: effect of hemodynamic and biological factors. Am J Physiol Heart Circ Physiol 304: H1455-H1470, 2013. First published March 15, 2013; doi:10.1152/ajpheart.00539.2012.-Atherosclerosis is a systemic disease with local manifestations. Low-density lipoprotein (LDL) accumulation in the subendothelial layer is one of the hallmarks of atherosclerosis onset and ignites plaque development and progression. Blood flow-induced endothelial shear stress (ESS) is causally related to the heterogenic distribution of atherosclerotic lesions and critically affects LDL deposition in the vessel wall. In this work we modeled blood flow and LDL transport in the coronary arterial wall and investigated the influence of several hemodynamic and biological factors that may regulate LDL accumulation. We used a three-dimensional model of a stenosed right coronary artery reconstructed from angiographic and intravascular ultrasound patient data. We also reconstructed a second model after restoring the patency of the stenosed lumen to its nondiseased state to assess the effect of the stenosis on LDL accumulation
Collective Charge Excitation in a Dimer Mott Insulating System
Charge dynamics in a dimer Mott insulating system, where a non-polar
dimer-Mott (DM) phase and a polar charge-ordered (CO) phase compete with each
other, are studied. In particular, collective charge excitations are analyzed
in the three different models where the internal-degree of freedom in a dimer
is taken into account. Collective charge excitation exists both in the
non-polar DM phase and the polar CO phase, and softens in the phase boundary.
This mode is observable by the optical conductivity spectra where the light
polarization is parallel to the electric polarization in the polar CO phase.
Connections between the present theory and the recent experimental results in
kappa-(BEDT-TTF)2Cu2(CN)3 are discussed.Comment: 5 pages, 4 figure
Um sistema Web para a gerência dos dados da produção integrada de frutas.
Qual a intensidade de infestação da Ceratitis Capitata no noroeste EspĂrito-Santense? E da Stenodiplosis sp (larva-do-broto-terminal) em cajueiros do norte cearense? Ou, ainda, da Grapholita moesta no nordeste rio-grandense? Para responder estas e outras perguntas semelhantes a Embrapa Informática Agropecuária desenvolveu o MIPWeb, um sistema informatizado desenvolvido com tecnologia Web, para auxiliar na gestĂŁo dos dados gerados pelo Manejo Integrado de Pragas (MIP), dentro do programa nacional da Produção Integrada de Frutas (PIF). Ele foi projetado para auxiliar os tĂ©cnicos do MinistĂ©rio da Agricultura, Pecuária e Abastecimento (MAPA) no acompanhamento da PIF concernente aos procedimentos de monitoramento e de controle do MIP e do nĂvel de infestação de moscas-das-frutas em todas as propriedades que participam da PIF
Weak itinerant ferromagnetism in Heusler type Fe2VAl0.95
We report measurements of the magnetic, transport and thermal properties of
the Heusler type compound Fe2VAl0.95. We show that while stoichiometric Fe2VAl
is a non-magnetic semi-metal a 5% substitution on the Al-site with the 3d
elements Fe and V atoms leads to a ferromagnetic ground state with a Curie
temperature TC = 33+-3 K and a small ordered moment ms = 0.12 mB/Fe in
Fe2VAl0.95. The reduced value of the ratio ms/mp = 0.08, where mp = 1.4 mB/Fe
is the effective Curie-Weiss moment, together with the analysis of the
magnetization data M(H,T), show magnetism is of itinerant nature. The specific
heat shows an unusual temperature variation at low temperatures with an
enhanced Sommerfeld coefficient, g = 12 mJK-2mol-1. The resistivity, r(T), is
metallic and follows a power law behavior r(T) = r0+AT^n with n = 1.5 below TC.
With applying pressure, TC decreases with the rate of (1/TC)(dTC /dP) = -0.061
GPa-1. We conclude substitution on the Al-site with Fe and V atoms results in
itinerant ferromagnetism with a low carrier density.Comment: 27 pages, 9 figure
Roundtable “Unification Church in Japan as a Sociocultural and Political Phenomenon”
In the second half of 2022, the Japanese political world was shaken by a major scandal: in July 2022, former Prime Minister and a prominent member of the ruling Liberal Democratic Party Abe Shinzō was killed at an election rally. The assassin, caught at the crime scene, declared that the murder was a revenge for the victim’s connection with the Unification Church, which, according to the perpetrator’s words, had led his family to financial ruin. Initially, this explanation seemed fantastical, but the investigation that followed revealed that both Abe Shinzō himself and many other Japanese politicians had been maintaining connections with the Unification Church for many years. This caused an uproar in Japanese society, especially given the rather controversial reputation of the Unification Church. On January 26, 2023, the Association of Japanologists and the research laboratory “Center for Japanese, Korean, and Mongolian Studies” of the Moscow State Institute of International Relations (MGIMO University) held a roundtable “Unification Church in Japan as a Sociocultural and Political Phenomenon”. The participants of the roundtable analyzed the situation around the Unification Church and its role in Japanese politics in detail, studied the specific features of the “new religions” in Japanese society, and considered the factors determining their influence on the political world of Japan
