We apply the Jeffrey-Kirwan method to compute the multiple integrals for the BCD-type Nekrasov partition functions of four-dimensional N = 2 supersymmetric gauge theories. We construct a graphical distinction rule to determine which poles are surrounded by their integration cycles. We compute the instanton correction of the “Sp(0)” pure super-Yang–Mills theory and find that Z Sp(0) k= (&#…

We propose a CP-safe minimal supersymmetric (SUSY) standard model in gravity mediation, where the phases of the Higgs B parameter, scalar trilinear couplings, and gaugino mass parameters are all aligned. Since all dangerous CP-violating phases are suppressed, we are now safe to consider low-energy SUSY scenarios under the assumption that the SUSY flavorchanging neutral current problem is solved…

A method is presented to simulate the propagation of elastic waves in a 2-D piecewise homogeneous domain composed of several regions of arbitrary shapes. The regions can be isolated within an elastic background or also embedded among themselves. The method is based on the indirect boundary element method (IBEM) in which the diffracted field is obtained as the contributions of distributed source…

Crowding conditions of larvae may have a significant impact on commercial production efficiency of some insects, such as Tenebrio molitor L. (Coleoptera: Tenebrionidae). Although larval densities are known to affect developmental time and growth in T. molitor, no reports were found on the effects of crowding on food utilization. The effect of larval density on food utilization efficiency of T. …

We investigate the interaction between  baryons in the 1S0 channel from 2+1-flavor lattice quantum chromodynamics (QCD) simulations. On the basis of the HAL QCD method, the  potential is extracted from the Nambu–Bethe–Salpeter wave function calculated on the lattice by using the PACS-CS gauge configurations with a lattice spacing of a  0.09 fm, a lattice volume of L  2.9 fm, and quark…

The Borborema province in NE Brazil is characterized by seismic sequences with small earthquakes that can last 10 yr or more. The seismicity in this region is concentrated in three main seismic zones. In thiswork,we investigate the stress field in one of these zones, the Acara´u Seismic Zone, which is located in the NW part of the Borborema province. This seismic zone exhibits earthquake seque…

The Lower Danube Basin is one of the most important loess regions from Europe, which have provided excellent archives for long-term high-resolution palaeoclimate studies. The aim of this paper is to derive new information on the Middle–Late Pleistocene palaeoenvironment from a high resolution multiproxy assessment of the iron mineralogical composition at the Costines¸ti loess-palaeosol sequ…

Motivated by the need to derive and characterize increasingly sophisticated seismic data analysis and inversion methods incorporating wave dissipation, we consider the problem of scattering of homogeneous and inhomogeneous waves from perturbations in five viscoelastic parameters (density, P- and S-wave velocities, and P- and S-wave quality factors), as formulated in the context of the Born appr…

We describe a novel multi-GeV photon detector which operates under an intense flux of neutrons. It is composed of lead–aerogel sandwich counter modules. Its salient features are high photon detection efficiency and blindness to neutrons. Monte Carlo (MC) simulations show that the efficiency for photons with energy larger than 1GeV is expected to be higher than 99.5% and that for 2 GeV/c neutr…

The field limit of a superconducting radio-frequency cavity made of a type II superconductor with a large Ginzburg–Landau parameter is studied, taking the effects of nano-scale surface topography into account. If the surface is ideally flat, the field limit is imposed by the superheating field. On the surface of cavity, however, nano-defects almost continuously distribute and suppress the sup…
