We have used atomistic simulations to study the role of electrostatic screening and charge correlation effects in self-assembly processes of ionic surfactants into micelles. Specifically, we employed grand canonical Monte Carlo simulations to investigate the critical micelle concentration (cmc), aggregation number, and micellar shape in the presence of explicit sodium chloride (NaCl). The two s...

We investigate phenomenologically viable fourand five-stack MSSM D-brane quivers which exhibit realistic fermion mass hierarchies. In our analysis, the mass hierarchies arise either from higher order terms containing the VEV’s of SM singlets or from D-instanton effects, where the latter utilizes either family splitting or a factorizable Yukawa matrix. Extending the systematic bottom-up analysis...

We study the effects of SO(10) D-terms on the allowed parameter space ( APS ) in models with t− b− τ and b− τ Yukawa unifiction. The former is allowed only for moderate values of the D-term, if very precise ( ≤ 5% ) unification is required. Next we constrain the parameter space by looking for different dangerous directions where the scalar potential may be unbounded from below ( UFB1 and UFB3 )...

We compute the full set of weak-scale gauge and Yukawa threshold corrections in the minimal supersymmetric standard model, and use them to study the effects of the supersymmetric particle spectrum on gauge and Yukawa coupling unification.

We demonstrate the stability under subsequent-to-leading logarithm corrections of the quartic scalar-field coupling constant λ and the running Higgs boson mass obtained from the (initially massless) effective potential for radiatively broken electroweak symmetry in the single-Higgs-Doublet Standard Model. Such subsequent-toleading logarithm contributions are systematically extracted from the re...

The S-wave time-independent Schrödinger equation with an isotropic velocity-dependent potential is considered .We have used perturbation theory to calculate the scattering phase shifts when the energy is changed by a small amount ∆E from an arbitrary unperturbed value E0. The validity of our results were tested by comparing the perturbed phase shifts to those obtained exactly by solving Schrödi...

BACKGROUND Evolocumab, a fully human monoclonal antibody against PCSK9, significantly reduced low-density lipoprotein-cholesterol (LDL-C) levels in Japanese patients by up to 76% when administered with a statin. We evaluated the efficacy and safety of 1 year of evolocumab in a pooled analysis of patients from the 12-week YUKAWA studies who continued into the open-label extension (OLE) OSLER stu...

We compute the Yukawa couplings among chiral fields in toroidal Type II compactifications with wrapping D6-branes intersecting at angles. Those models can yield realistic standard model spectrum living at the intersections. The Yukawa couplings depend both on the Kähler and open string moduli but not on the complex structure. They arise from worldsheet instanton corrections and are found to be ...

We describe the potential produced by a point electric charge placed into a constant magnetic field, so strong that the electron Larmour length is much shorter than its Compton length. The standard Coulomb law is modified due to the vacuum polarization by the external magnetic field. Only mode-2 photons mediate the static interaction. The corresponding vacuum polarization component, taken in th...
