The effects of unburned-gas temperature on intrinsic instability of premixed flames at high Lewis numbers under the adiabatic and non-adiabatic conditions

open access: yesMechanical Engineering Journal, 2017
We treated numerically premixed flames at high Lewis numbers under the adiabatic and non-adiabatic conditions to elucidate the effects of unburned-gas temperature on intrinsic instability.

Origin of the quasi-quantized Hall effect in ZrTe5

open access: yesNature Communications, 2021
A 3D quantum Hall effect has been reported in Dirac semimetal ZrTe5 due to a magnetic-field-driven Fermi surface instability. Here, the authors show evidence of quasi-quantized Hall response without Fermi surface instability, but they argue that it is ...

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

open access: yesNihon 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.

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

open access: yesJournal 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.

Intrinsic Instability of Perovskite Solar Cells: The Role of a Hole-Blocking Layer

open access: yesCrystals, 2023
Among the emerging photovoltaic technologies, perovskite solar cells (PSCs) are the most promising ones with efficiencies close to crystalline silicon. However, stability and reliability issues are still a limit for future applications of this technology.

Subtalar instability

open access: yesJournal of Orthopaedic Surgery, 2023
Subtalar instability is a confusing yet important condition in patients with lateral ankle instability. The author will explore subtalar kinematics, and how they are closely related to the joint stability of the subtalar joint, both with respect to its ...

Paradoxes and wonders of intrinsic disorder: Stability of instability [PDF]

open access: yesIntrinsically Disordered Proteins, 2017
This article continues a series of short comments on the paradoxes and wonders of the protein intrinsic disorder phenomenon by introducing the "stability of instability" paradox. Intrinsically disordered proteins (IDPs) are characterized by the lack of stable 3D-structure, and, as a result, have an exceptional ability to sustain exposure to extremely ...

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

open access: yesJournal 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.

Joint Effect of Heterogeneous Intrinsic Noise Sources on Instability of MEMS Resonators [PDF]

open access: yesElectronics, 2015
This article's focus is on the numerical estimation of the overall instability of microelectromechanical-system-based (MEMS) resonators, caused by intrinsic noise mechanisms that are different in nature (electrical, mechanical or chemical). Heterogeneous

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

open access: yesFrontiers 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.
