A LArge Reservoir Simulator (LARS) was equipped with an electrical resistivity tomography (ERT) array to monitor hydrate formation and dissociation experiments. During two hydrate formation experiments reaching 90 per cent bulk hydrate saturation, frequent measurements of the electrical properties within the sediment sample were performed. Subsequently, several common mixing rules, including t…

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…

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. …

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…

This study includes a detailed experimental investigation of the spatial and temporal spectroscopic emission of an argon plasma jet discharge. The study is carried out in ambient air and quenching by inflowing air species is considered. The optical emission spectroscopy of neutral atomic spectral lines and molecular bands, over a range of plasma process parameters, is investigated. Wavelength-…

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…

We propose natural inflation from the heterotic string theory on the “Swiss-Cheese” Calabi– Yau manifold with multiple U(1) magnetic fluxes. Such multiple U(1) magnetic fluxes stabilize the same number of the linear combination of the universal axion and Kähler axions, and one of the Kähler axions is identified as the inflaton. This axion decay constant can be determined by the size of…

We investigate the effects of triple-α and 12C(α, γ )16O reaction rates on the production of supernova yields for a massive star of 25 M. We combine the reaction rates to examine the rate dependence, where the rates are considered to cover the possible variation of the rates based on experiments on the earth and on theory. We adopt four combinations of the reaction rates from tw…
