On the stability of thin-shell wormholes [PDF]

, 2016
A thin-shell wormhole is theoretically constructible by surgically grafting together two Schwarzschild spacetimes using the so-called cut-and-paste technique.

Preparation and luminescent properties of CdS/ZnO core shell quantum dots

上海师范大学学报. 自然科学版, 2015
The ZnO,CdS,and CdS/ZnO quantum dots have been successfully prepared through a facial sol-gel method.After annealing treatment,the CdS/ZnO core-shell structure with a ZnO shell of 10 nm was acquired.The CdS/ZnO core-shell structure resulted in the ...

Improved Off-Shell Scattering Amplitudes in String Field Theory and New Computational Methods

, 2003
We report on new results in Witten's cubic string field theory for the off-shell factor in the 4-tachyon amplitude that was not fully obtained explicitly before.

Impact crater morphology and the structure of Europa's ice shell

, 2017
We performed numerical simulations of impact crater formation on Europa to infer the thickness and structure of its ice shell. The simulations were performed using iSALE to test both the conductive ice shell over ocean and the conductive lid over warm ...

Structural damping in sandwich shells

Engineering Transactions, 1976
The basic equations governing the motion of sandwich shells are derived through the use of a variational procedure. Structural damping is investigated in the case of a cylindrical sandwich shell with dissimilar facings, executing axially symmetric free vibrations.

Rough droplet model for spherical metal clusters

, 1998
We study the thermally activated oscillations, or capillary waves, of a neutral metal cluster within the liquid drop model. These deformations correspond to a surface roughness which we characterize by a single parameter $\Delta$.
