Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Attitude and orbit coupling of planar helio-stable solar sails

open access: yes, 2019
The coupled attitude and orbit dynamics of solar sails is studied. The shape of the sail is a simplified quasi-rhombic-pyramid that provides the structure helio-stablility properties.

ORBITS IN A NON-KERR DYNAMICAL SYSTEM [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2011
We study the orbits in a Manko–Novikov type metric (MN) which is a perturbed Kerr metric. There are periodic, quasi-periodic, and chaotic orbits, which are found in configuration space and on a surface of section for various values of the energy E and the z-component of the angular momentum Lz. For relatively large Lz there are two permissible regions

Coupled orbit-attitude dynamics of high area-to-mass ratio (HAMR) objects: influence of solar radiation pressure, Earth’s shadow and the visibility in light curves [PDF]

open access: yes, 2013
The orbital and attitude dynamics of uncontrolled Earth orbiting objects are perturbed by a variety of sources. In research, emphasis has been put on operational space vehicles. Operational satellites typically have a relatively compact shape, and hence,

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Spin torque on the surface of graphene in the presence of spin orbit splitting

open access: yesAIP Advances, 2013
We study theoretically the spin transfer torque of a ferromagnetic layer coupled to (deposited onto) a graphene surface in the presence of the Rashba spin orbit coupling (RSOC). We show that the RSOC induces an effective magnetic field, which will result

Determination of Initial Conditions for Satellite Formation Flying in Elliptical Orbits [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2005
The initial conditions that generate bounded motion in eccentric reference orbit are determined for satellite formation flying. Because Hill's equations cannot describe the relative motion between two satellites in eccentric orbit, a new relative ...

An improved effective-one-body Hamiltonian for spinning black-hole binaries

open access: yes, 2010
Building on a recent paper in which we computed the canonical Hamiltonian of a spinning test particle in curved spacetime, at linear order in the particle's spin, we work out an improved effective-one-body (EOB) Hamiltonian for spinning black-hole ...
