Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A Survey of Stability of Peaked Solitons II: Multicomponent Case
峰值孤子 稳定性 多组分案例
2023/4/27
Peaked soliton dynamics is one of the most intriguing features of the Camassa-Holm-type integrable equations. In this talk, I will give a review on the issue of the stability of peaked solitons, inclu...

support and John Besant-Jones for helpful comments. The findings and conclusions of this paper are...
MAINTAINING MOMENTUM IN TERRESTRIAL LASER SCANNING: A UK CASE STUDY
Archiving Cultural Heritage Management
2015/8/13
Terrestrial laser scanning has been rapidly adopted around the world as a tool for capturing three-dimensional survey data in
a variety of applications. This rapid take up continues, but clients, and...
THE CASE FOR UNLICENSED SPECTRUM
SPECTRUM v
2015/7/21
The introduction in the past few years of mobile devices such as the iPhone, iPad
and Android phones has led to vast increases in the use of wireless data communications,
and most forecasters anti...
Two Comparative Case Studies of b-quark and c-quark Physics: • Particle-antiparticle Mixing • Radiative Weak Decays
Dollar mixed weak radioactive decay D meson pseudo-scalar meson particle antiparticles
2014/12/23
We discuss prospects for detecting the two charm-related phenomena of $D^0$-${\bar D}^0$ mixing and weak radiative decays of $D$ mesons ({\it e.g.} $D\to K^* + \gamma$). A general update of particle-a...
On the unconstrained expansion of a spherical plasma cloud turning collisionless : case of a cloud generated by a nanometer dust grain impact on an uncharged target in space
spherical plasma collisionless nanometer dust grain impact space Plasma Physics
2012/5/29
Nano and micro meter sized dust particles travelling through the heliosphere at several hundreds of km/s have been repeatedly detected by interplanetary spacecraft. When such fast moving dust particle...
Opinion formation in time-varying social networks: The case of Naming Game
Opinion formation time-varying social networks The case of Naming Game Social and Information Networks
2012/4/19
We study the dynamics of the Naming Game as an opinion formation model on time-varying social networks. This agent-based model captures the essential features of the agreement dynamics by means of a m...
Surface states on a topologically non-trivial semimetal: The case of Sb(110)
Surface states topologically non-trivial semimetal Sb(110)
2012/2/27
The electronic structure of Sb(110) is studied by angle-resolved photoemission spectroscopy and first-principle calculations, revealing several electronic surface states in the projected bulk band gap...
Under so-called primitive ontology approaches, in fully describing the history of a quantum system, one thereby attributes interesting properties to regions of spacetime. Primitive ontology approaches...
Nearest Neighbor Distances on a Circle: Multidimensional Case
Multidimensional Case Mathematical Physics Dynamical Systems
2011/9/16
Abstract: We study the distances, called spacings, between pairs of neighboring energy levels for the quantum harmonic oscillator. Specifically, we consider all energy levels falling between E and E+1...
Quantum Monte Carlo facing the Hartree-Fock symmetry dilemma: The case of hydrogen rings
Quantum Monte Carlo Hartree-Fock hydrogen rings
2011/8/5
Abstract: When using Hartree-Fock (HF) trial wave functions in quantum Monte Carlo calculations, one faces, in case of HF instabilities, the HF symmetry dilemma in choosing between the symmetry-adapte...
Simulation of spin-polarized scanning tunneling microscopy on complex magnetic surfaces: The case of a Cr monolayer on Ag(111)
spin-polarized scanning tunneling complex magnetic surfaces Cr monolayer Ag
2011/8/17
Abstract: We propose an atom-superposition-based method for simulating spin-polarized scanning tunneling microscopy (SP-STM) from first principles. Our approach provides bias dependent STM images in h...
