Guideline for standardized approach in the treatment of the Mal de Debarquement syndrome

open access: yesFrontiers in Neurology
IntroductionMal de Debarquement Syndrome (MdDS) is a debilitating neuro-otological disorder. Patients experience almost continuously a perception of self-motion.

The density profile of equilibrium and non-equilibrium dark matter halos [PDF]

open access: yes, 1999
We study the diversity of the density profiles of dark matter halos based on a large set of high-resolution cosmological simulations of 256^3 particles.

Wearable, stable, highly sensitive hydrogel–graphene strain sensors

open access: yesBeilstein Journal of Nanotechnology, 2019
A stable and highly sensitive graphene/hydrogel strain sensor is designed by introducing glycerol as a co-solvent in the formation of a hydrogel substrate and then casting a graphene solution onto the hydrogel in a simple, two-step method.

Multi-photon resonances in Josephson junction-cavity circuits

open access: yesNew Journal of Physics, 2021
We explore the dissipative dynamics of nonlinearly driven oscillator systems tuned to resonances where multiple excitations are generated. Such systems are readily realised in circuit QED systems combining Josephson junctions with a microwave cavity and ...

Non-Poisson processes: regression to equilibrium versus equilibrium correlation functions

open access: yes, 2004
We study the response to perturbation of non-Poisson dichotomous fluctuations that generate super-diffusion. We adopt the Liouville perspective and with it a quantum-like approach based on splitting the density distribution into a symmetric and an anti ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Effectively Incorporating Small Reserves into National Systems of Protected and Conserved Areas

open access: yesDiversity
Received wisdom has argued that large protected areas are superior to small reserves, based on island biogeography theory, economies of scale, and the need to sustain viable populations of top predators and other large ranging or dispersive species.

Prolonged microgravity induces reversible and persistent changes on human cerebral connectivity

open access: yesCommunications Biology, 2023
rs-fMRI is used to investigate human brain connectivity changes induced by prolonged microgravity in cosmonauts before and after spaceflight, with both persistent and reversible location specific changes in connectivity being observed.

Equilibrium Chemical Engines

open access: yes, 1997
An equilibrium reversible cycle with a certain engine to transduce the energy of any chemical reaction into mechanical energy is proposed. The efficiency for chemical energy transduction is also defined so as to be compared with Carnot efficiency ...

Equilibrium and non-equilibrium Ising models by means of PCA [PDF]

open access: yes, 2013
We propose a unified approach to reversible and irreversible PCA dynamics, and we show that in the case of 1D and 2D nearest neighbour Ising systems with periodic boundary conditions we are able to compute the stationary measure of the dynamics also when
