Numerical Studies on Propagation Mechanisms of Gaseous Detonations in the Inhomogeneous Medium

open access: yesApplied Sciences, 2020
Numerical simulation of propagation mechanisms of gaseous detonations in the inhomogeneous medium is studied by using the reactive Euler equations coupled with a two-step chemical reaction model.

Capillary instability in nanowire geometries [PDF]

open access: yes, 2014
The vapor-liquid-solid (VLS) mechanism has been applied extensively as a framework for growing single-crystal semiconductor nanowires for applications spanning optoelectronic, sensor and energy-related technologies.

Intrinsic instability of premixed flames in cryogenic environment (Effects of unburned-gas temperature and heat loss)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
The effects of unburned-gas temperature and radiative heat loss on the intrinsic instability of premixed flames in cryogenic environment were studied.

Machine-learning predicts genomic determinants of meiosis-driven structural variation in a eukaryotic pathogen

open access: yesNature Communications, 2021
Structural variation in genomes of the same species is frequent but what drives the rearrangements remains unclear. Machine-learning of rearrangement patterns among telomere-to-telomere assemblies can accurately identify regions of intrinsic DNA ...

Instability of lean H2-O2-CO2 premixed flames on a flat burner

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Global warming and air pollution mainly caused by emissions of CO2 and NOx are serious problems. We focus on a lean H2-O2 premixed flame because H2-O2 premixed flame emits no CO2 and NOx.

Stable oscillating nonlinear beams in square-wave-biased-photorefractives [PDF]

open access: yes, 2000
We demonstrate experimentally that in a centrosymmetric paraelectric non-stationary boundary conditions can dynamically halt the intrinsic instability of quasi-steady-state photorefractive self-trapping, driving beam evolution into a stable oscillating ...

The Yih Instability in Layered Lava Flow May Initiate the Pāhoehoe to ‘a‘ā Lava Transition

open access: yesGeophysical Research Letters, 2023
Most basaltic lavas begin flowing as pāhoehoe but sometimes transition into ‘a‘ā. Field observations and previous models have demonstrated that the rheology of smooth, liquid‐like pāhoehoe is distinct from rough, pasty ‘a‘ā, but the cause of this ...

Helicoidal instability of a scroll vortex in three-dimensional reaction-diffusion systems

open access: yes, 1998
We study the dynamics of scroll vortices in excitable reaction-diffusion systems analytically and numerically. We demonstrate that intrinsic three-dimensional instability of a straight scroll leads to the formation of helicoidal structures. This behavior

Intrinsic instabilities in Fermi glasses

open access: yesPhysical Review B
We study in this paper the effect of weak, short-ranged interaction on disordered metals. Through analysing the interaction matrix elements between different eigenstates of the non-interacting and corresponding Hartree-Fock single-particle Hamiltonian, we argue that as a result of localized single-particle eigenstates around the Fermi surface, the ...
