Microscopic simulation of superconductor/topological insulator proximity structures

Proximity effect in graphene-topological-insulator heterostructures.

We formulate a continuum model to study the low-energy electronic structure of heterostructures formed by graphene on a strong three-dimensional topological insulator (TI) for the cases of both commensurate and incommensurate stacking. The incommensurability can be due to a twist angle between graphene and the TI surface or a lattice mismatch between the two systems. We find that the proximity ...

Microscopic Structures Analysis and Experimental Research of Beak

To reveal the mechanism of the easy discretization and low damage in kernel dispersal, this paper analyzes the microscopic analysis of beak structures and finds that maxillary outside cells of the beak are dense and hard. Besides, the cuticle wrapping on maxilla of chicken's beak can reduce corn kernels damage in the discrete process of ear. From force test of corn ear, we find that value of x ...

Simulation of Pedestrian Dynamics with Macroscopic and Microscopic Mathematical Models

Here, we collect two parts of a research project on the pedestrian flow modeling. Rapid growth in the volume of public transport and the need for its reasonable, efficient planning have made the description and modeling of transport and pedestrian behaviors as important research topics in the past twenty years. First, we present a macroscopic model for the pedestrian flow based on continuum mec...

Proximity of Vital Structures to the Clavicle: Comparison of Fractured and Non-fractured Side

  Background: Previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. We were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles.   Methods: We retrospectively identified all patients with a clavicle fracture between July 2001 and Octobe...
