autoimmune myasthenia gravis (mg) is a unique disease among all autoimmune disorders in two ways. first, there are a wide range of sub-specialties involved in the diagnosis and management of mg; secondly mg is an autoimmune disorder whose autoimmunity is well established. in this paper i will cover these topics: history and epidemiology of mg followed by a brief overview on physiology of neurom...

In this paper we derive a lower bound, independent from the number of atoms N , for the minimal interatomic distances between atoms in a cluster whose total energy is modelled by means of the so called Morse potential. A similar result was previously proven for Lennard-Jones clusters but the proof can not be extended to Morse clusters. Besides the theoretical interest, the derivation of this lo...

Effective interatomic potentials are frequently utilized for large-scale simulations of materials. In this work, we generate an effective interatomic potential, with Niobium as an example, using the force-matching method derived from a material database which is created by the first-principle molecular dynamics. It is found that the potentials constructed in the present work are more transferab...

We explore the possibility of obtaining de Sitter vacua in strongly coupled heterotic models by adding various corrections to the supergravity potential energy. We show that, in a generic compactification scenario, Fayet-Illiopulos terms can generate a de Sitter vacuum. The cosmological constant in this vacuum can be fine tuned to be consistent with observation. We also study moduli potentials ...

A state-of-the-art three-dimensional Langevin approach is used to explore the influence of the potential-energy surface on the dynamical evolution of a system along its path to fission. Two macroscopic models have been used to parametrize the energy landscape: the Finite Range Liquid Drop Model (FRLDM) [1] and the Lublin-Strasbourg Drop (LSD) model [2]. The former is commonly used for the descr...
