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.

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.

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 ...

Driven Intrinsic Localized Modes in a Coupled Pendulum Array

open access: yes, 2007
Intrinsic localized modes (ILMs), also called discrete breathers, are directly generated via modulational instability in an array of coupled pendulums. These ILMs can be stabilized over a range of driver frequencies and amplitudes. They are characterized

Diffusion-induced vortex filament instability in 3-dimensional excitable media

open access: yes, 1999
We studied the stability of linear vortex filaments in 3-dimensional (3D) excitable media, using both analytical and numerical methods. We found an intrinsic 3D instability of vortex filaments that is diffusion-induced, and is due to the slower diffusion

In vitro effect of canine hyperimmune sera on TNFa activity [PDF]

open access: yes, 2006
[Introduction]: Septic shock in dogs is caused by cardiovascular and vasomotor failure associated with an uncontrolled intrinsic release of inflammatory mediators [1–5].

Competition between intrinsic and extrinsic effects in the quenching of the superconducting state in FeSeTe thin films

open access: yes, 2016
We report the first experimental observation of the quenching of the superconducting state in current-voltage characteristics of an iron-based superconductor, namely, in FeSeTe thin films.
