New Concepts in Carpal Instability

, 2021
Our understanding of carpal stability and kinematics continues to evolve through research and clinical experience. Conventional thinking relies on the belief that the interosseous ligaments of the proximal carpal row maintain stability primarily whilst ...

Dynamic behavior and flame acceleration of outwardly expanding flame in hydrogen-air mixture

Nihon Kikai Gakkai ronbunshu, 2016
From the perspective of safety, it is necessary to assess the risk of hydrogen-air deflagration accurately. Especially, flame propagation velocity is one of the most important factors.

A matrix stability analysis of the carbuncle phenomenon [PDF]

, 2004
The carbuncle phenomenon is a shock instability mechanism which ruins all efforts to compute grid-aligned shock waves using low-dissipative upwind schemes.

Numerical Study on the Intrinsic Instability of High-Temperature Premixed Flames under the Conditions of Constant Density and Constant Pressure in the Unburned Gas

Journal of Fluid Science and Technology, 2013
We studied numerically the intrinsic instability of high-temperature premixed flames, where the burned-gas temperature was constant, under the conditions of constant density and constant pressure in the unburned gas.

Heat-loss effects on the chaotic behavior of cellular premixed flames generated by intrinsic instability

Journal of Thermal Science and Technology, 2007
Heat-loss effects on the chaotic behavior of cellular premixed flames generated by intrinsic instability were studied by two-dimensional unsteady calculations of reactive flows based on the compressible Navier-Stokes equation.

Role of the intrinsic subtalar ligaments in subtalar instability and consequences for clinical practice

Frontiers in Bioengineering and Biotechnology, 2023
Subtalar instability (STI) is a disabling complication after an acute lateral ankle sprain and remains a challenging problem. The pathophysiology is difficult to understand.

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

Applied 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.

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

Nature 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

Nihon 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.
