Subtalar instability

Journal 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 intrinsic ligaments and its extrinsic ligaments.

Chromosomal instability drives metastasis through a cytosolic DNA response

Nature, 2017
Chromosomal instability is a hallmark of cancer that results from ongoing errors in chromosome segregation during mitosis. Although chromosomal instability is a major driver of tumour evolution, its role in metastasis has not been established.

ATR is required to complete meiotic recombination in mice

Nature Communications, 2018
ATR kinase is required for meiosis in non-mammalian model organisms. Here the authors demonstrate, using a hypomorphic Atr mutation and chemical inhibition, that ATR is also essential for male meiosis in mouse, regulating meiotic recombination and ...

Dispersion Instability in Strongly Interacting Electron Liquids [PDF]

, 2005
We show that the low-density strongly interacting electron liquid, interacting via the long-range Coulomb interaction, could develop a dispersion instability at a critical density associated with the approximate flattening of the quasiparticle energy ...

Physical models of streaming instabilities in protoplanetary discs [PDF]

, 2020
We develop simple, physically motivated models for drag-induced dust–gas streaming instabilities, which are thought to be crucial for clumping grains to form planetesimals in protoplanetary discs.

The subcritical baroclinic instability in local accretion disc models

, 2010
(abridged) Aims: We present new results exhibiting a subcritical baroclinic instability (SBI) in local shearing box models. We describe the 2D and 3D behaviour of this instability using numerical simulations and we present a simple analytical model ...

Research on the Impact of Geopolitical Instability on Russian Trade

International Journal of Innovative Science and Research Technology
This study examines how global and country- specific geopolitical instability affects Russian trade using data from 1996 to 2021. A panel regression model analyzes trade between Russia and its 15 top trading partners, exploring both direct and indirect ...

Tangling clustering instability for small particles in temperature stratified turbulence

, 2013
We study particle clustering in a temperature stratified turbulence with small finite correlation time. It is shown that the temperature stratified turbulence strongly increases the degree of compressibility of particle velocity field.

Energy dynamics in a simulation of LAPD turbulence [PDF]

, 2012
Energy dynamics calculations in a 3D fluid simulation of drift wave turbulence in the linear Large Plasma Device (LAPD) [W. Gekelman et al., Rev. Sci. Inst. 62, 2875 (1991)] illuminate processes that drive and dissipate the turbulence. These calculations
