The plasma-wall dynamic: Well-posedness

Badsi, Mehdi · Grosse, Bastien

We prove existence and uniqueness in BV for a Vlasov-Poisson boundary value problem which takes into account a nonlinear boundary condition at the boundary on the electric potential. It models the dynamical interaction between a plasma and an electrically isolated metallic wall. The nonlinear boundary condition is the...

Unveiling Organic Molecule Incorporation in Ice: Implications for Fundamental Processes to Origin of Life

Iryna POLISHCHUK · Hadar SHAKED · Johanna SKLAR · Boaz POKROY · y 1 más

Ice in glaciers, sea ice, and permafrost plays a crucial role in climate, sea-level, and scientific research. Recent discoveries have revealed the potential for various organic molecules to become trapped in ice, leading to unique chemical reactions and environmental processes. This study leverages our expertise in inc...

Bone marrow remodeling and brain–bone marrow crosstalk in Alzheimer’s disease-like neurodegeneration

Konstantin, Yenkoyan · Tigran, Davtyan · Hamlet, Torosyan · Sona, Galstian · y 1 más

Alzheimer's disease (AD) is increasingly recognized as a systemic disorder involving not only central neurodegeneration but also alterations in peripheral immune regulation and systemic homeostasis. Among these, the bone marrow represents a critical yet underexplored interface between the brain and systemic homeostasis...

Following the dealloying of HEAs

Jacob KIRKENSGAARD · Nicolas SCHLEGEL · Rebecca Katharina PITTKOWSKI · Jens EDELVANG-PEJRUP · y 3 más

High Entropy Alloys are a promising new class of materials. Specifically, PtPdFeCoNi showed promising activites for ORR, making it a possible candidate for as a next-generation catalyst for PEMFCs. However, there is little known about the degradation of alloys, especially this HEA. Anomalous SAXS at the Pt K-edge and t...

The Berger-Wang formula for order-preserving homogeneous maps on cones

Brian Lins · Aljoša Peperko

We prove that the joint spectral radius and generalized spectral radius are equal for any bounded, equicontinuous family of order-preserving, homogeneous maps on a polyhedral cone. We also consider conditions which guarantee that the semigroup generated by a family of order-preserving, homogeneous maps is bounded when...

Cryo-electron microscopy EPN BAG

Catarina SILVA · Lindsay MCGREGOR · Romain LINARES · Guy SCHOEHN

At the EPN campus level structural biology work is carried out in all the 4 institutes (IBS, ESRF, ILL and EMBL). Today all structural biology groups are turning to cryo-EM. The EM demand is therefore extremely high and present in the 4 Institutes. In a nutshell, there are more than 45 PIs that could benefit from Krios...

Determination of O and Si exsolution during the crystallization of iron at planetary cores conditions determined using X-ray Absorption Spec

Angelika ROSA · Daniele ANTONANGELI · Lola PERRUCHON-MONGE · Serena DOMINIJANNI · y 2 más

Planetary cores are constituted of iron alloyed with lighter elements (S, C, O, Si or H). Understanding the phase diagrams as well as the physical properties of these alloys under extreme conditions is crucial to model the thermal evolution and the dynamics of core crystallization, at the origin of the magnetic field....

The Structure of Lewy Bodies by Scanning X-ray Diffraction and Infrared Spectromicroscopy

Tim SALDITT · Titus CZAJKA · Markus OSTERHOFF (ORCID: 0000-0002-7865-515X) · Hendrik BRUNS · y 2 más

A crucial step in the etiopathology of Parkinson’s disease (PD) is the development of protein aggregates in the brain, which are known as Lewy Bodies (LB) and contain the protein α-synuclein as a major component. We have recently shown that LBs can form in a minimal system, based on cell culture. The current proposal n...

Temporal variability of tryptophan-like fluorescence as a surrogate for microbial contamination and its association with flow components of karst spring discharge

Niladri, Chowdhury · Ruhhee, Tabbussum · Patrick, Morrissey · David, O'Connell · y 1 más

This study investigated the relationship between temporal variability of microbial contamination at a karst spring and the different flow components of a karst groundwater system in western Ireland. A high frequency tryptophan like fluorescence (TLF) concentration time series was collected over 12 months as a surrogate...

Understanding the interplay between structural chirality and molecular magnetism

Lapo QUERCI · Daniele SARTINI · Niccolò GIACONI · Fabrice WILHELM · y 1 más

A novel family of chiral SMM molecules will be investigated here at the level of a monolayer deposit assembled on Au (111) via thermal sublimation in order to evaluate if, in agreement with the reports on bulk, the magnetization dynamics is strongly influenced by the specific arrangement of the molecules in the lattice...
