Wind-shearing in gaseous protoplanetary disks

open access: yes, 2010
One of the first stages of planet formation is the growth of small planetesimals and their accumulation into large planetesimals and planetary embryos. This early stage occurs much before the dispersal of most of the gas from the protoplanetary disk. Due

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

On calculation of the stability radius for a minimum spanning tree

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2017
We consider a minimum spanning tree problem in the situation where weights of edges are exposed to independent perturbations. We study a quantitative characteristic of stability for a given optimal solutions of the problem.

Les relations sociales, frein ou moteur de la durabilité

open access: yesDéveloppement Durable et Territoires, 2013
Development paths may include contradictions between the different dimensions of sustainability. This article shows the usefulness of the notion of radius of trust in order to evaluate the contribution of social relationships to sustainability.

Efficient Method for Computing Lower Bounds on the $p$-radius of Switched Linear Systems

open access: yes, 2016
This paper proposes lower bounds on a quantity called $L^p$-norm joint spectral radius, or in short, $p$-radius, of a finite set of matrices. Despite its wide range of applications to, for example, stability analysis of switched linear systems and the ...

An adaptive, fully implicit multigrid phase-field model for the quantitative simulation of non-isothermal binary alloy solidification [PDF]

open access: yes, 2008
Using state-of-the-art numerical techniques, such as mesh adaptivity, implicit time-stepping and a non-linear multi-grid solver, the phase-field equations for the non-isothermal solidification of a dilute binary alloy have been solved.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

On the stability of convex symmetric polytopes of matrices

open access: yesElectronic Journal of Differential Equations, 2000
In this warticle we investigate the stability properties of a convex symmetric time-varying second-order matrix's polytope depending on a real positive parameter $r$.

A new mechanism for radius stabilization in warped supersymmetry [PDF]

open access: yesPhysics Letters B, 2005
A new mechanism for the radius stabilization is proposed in a 5D super-Yang-Mills model in the warped background of ${AdS}_5$. Dominant 1-loop contribution to the supersymmetric 4D effective potential is estimated to depend on the radion. The minimization of the effective potential incorporating the tree potential and a Fayet-Iliopoulos $D$-term for ...
