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...

Atolls are faithful recorders helping us understand eustatic variations, the evolution of carbonate production through time, and changes in magmatic hotspots activity. Several early Cretaceous Mid-Pacific atolls were previously investigated ocean drilling, but due to low quality vintage seismic data available, few spatial constraints exist on their stratigraphic large-scale diagenesis. Here, we...

The Lansdowne Bank is a partly drowned, isolated carbonate platform of around 4000 km2 located 300 km west New Caledonia, in the SW Pacific Ocean, water depths 20 to 100 m. multibeam bathymetric data, high resolution seismic reflection profiles and sediment gravity cores have been acquired on bank top adjacent slopes. This dataset reveals an almost continuous 4 wide outer reef rim ca. 50 m dept...

With the Upper Cambrian Xixiangchi Formation in eastern Sichuan Basin as target, this study investigates various diagenetic events during different stages deep dolomite reservoirs, accompanied by evaluations of their effects on formation and evolution reservoir rock. A series experiments are implemented core outcrop samples, including petrologic analysis, fluid inclusion rare earth minor elemen...

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 ...
