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.

Efficient parametric amplification in high and very high frequency piezoelectric nanoelectromechanical systems [PDF]

open access: yes, 2010
Parametric amplification in nanomechanical structures is demonstrated by modulating a purely intrinsic mechanical parameter of the system—the stress—via piezoelectric electromechanical coupling.

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
