QCD Laplace sum-rules are an important tool to extract information about bound states of quarks from perturbative QCD with non-perturbative effects of QCD condensates. Applying the QCD Laplace sum-rules to strange and non-strange heavy-light diquarks, I compare their masses. Diquark correlation functions are renormalized using the diagrammatic renormalization method. It is found that the...

344. Theory for electron-phonon systems at high levels of Joule heating: Spontaneous symmetry breaking with possible applications to chemical systems.

Recent work on dissipative electron-phonon type systems will be reviewed. A Boltzmann transport equation was formulated which accounts for second order collisions with an electron-phonon vertex and a three-phonon vertex. This approach reveals the existence of two forces perpendicular to the primary direction of electrical current, equally and oppositely acting on electrons and phonons. ...

Despite the development in Engineering, the structure such as bridge continue to collapse due to fluid loads effects. Their combination on a bridge pier can also induced catastrophic damages. Less attention in literature has been given to bridge pier dynamics under transversal flow. This work describes the dynamic vibration, including theoretical non-linear dynamics analysis, of a bridge pier...
