Bubble dynamics in DNA

open access: yes, 2003
The formation of local denaturation zones (bubbles) in double-stranded DNA is an important example for conformational changes of biological macromolecules. We study the dynamics of bubble formation in terms of a Fokker-Planck equation for the probability

Bubble Universe Dynamics After Free Passage [PDF]

open access: yes, 2014
We consider bubble collisions in single scalar field theories with multiple vacua. Recent work has argued that at sufficiently high impact velocities, collisions between such bubble vacua are governed by 'free passage' dynamics in which field ...

Mechanism study of bubble dynamics under the buoyancy effects

open access: yesNuclear Analysis, 2023
The motion of a single bubble in a 2-D vertical channel filled with stagnant or moving fluid is simulated for various sets of conditions using the computational fluid dynamics(CFD) method. The volume of fluid (VOF) model is applied to track the interface

Gravitational waves from bubble dynamics: Beyond the Envelope

open access: yes, 2019
We study gravitational-wave production from bubble dynamics (bubble collisions and sound waves) during a cosmic first-order phase transition with an analytic approach.

A Review of Bubble Dynamics in Liquid Metals

open access: yesMetals, 2021
Gas bubbles are of major importance in most metallurgical processes. They promote chemical reactions, homogenize the melt, or float inclusions. Thus, their dynamics are of crucial interest for the optimization of metallurgical processes.

On the dynamics of a shock–bubble interaction [PDF]

open access: yesJournal of Fluid Mechanics, 1996
We present a detailed numerical study of the interaction of a weak shock wave with an isolated cylindrical gas inhomogeneity. Such interactions have been studied experimentally in an attempt to elucidate the mechanisms whereby shock waves propagating through random media enhance mixing.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Numerical simulation data of an elongated cavitation bubble induced by long-pulsed laser

open access: yesData in Brief, 2023
The simulation data presented in this paper describes the formation and growth of an elongated bubble induced by a long-pulsed laser. The simulation is performed using the M2C solver, which is a recently developed three-dimensional finite volume Navier ...

Dynamics of moving bubbles in single and binary component systems [PDF]

open access: yes, 1968
Dynamics of a single bubble moving in a quiescent liquid is analyzed for single and binary component systems. The transport of energy and/or mass at thermodynamic-phase equilibrium governs the dynamics of the bubble at its ...

Numerical simulations of non-spherical bubble collapse [PDF]

open access: yes, 2009
A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...
