Adiabatic non-equilibrium steady states in the partition free approach
Consider a small sample coupled to a finite number of leads, and assume that
the total (continuous) system is at thermal equilibrium in the remote past. We
construct a non-equilibrium steady state (NESS) by adiabatically turning on an
electrical bias between the leads. The main mathematical challenge is to show
that certain adiabatic wave operators exist, and to identify their strong limit
when the adiabatic parameter tends to zero. Our NESS is different from, though
closely related with the NESS provided by the Jak{\v s}i{\'c}-Pillet-Ruelle
approach. Thus we partly settle a question asked by Caroli {\it et al} in 1971
regarding the (non)equivalence between the partitioned and partition-free
approaches
TIA1 Mutations in Amyotrophic Lateral Sclerosis and Frontotemporal Dementia Promote Phase Separation and Alter Stress Granule Dynamics.
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are age-related neurodegenerative disorders with shared genetic etiologies and overlapping clinical and pathological features. Here we studied a novel ALS/FTD family and identified the P362L mutation in the low-complexity domain (LCD) of T cell-restricted intracellular antigen-1 (TIA1). Subsequent genetic association analyses showed an increased burden of TIA1 LCD mutations in ALS patients compared to controls (p = 8.7 × 1
Production and fragmentation of lysozyme films at 355 nm by pulsed laser deposition (PLD)
Ferroelectric (NaBi)TiO-BaTiO thin films obtained by pulsed laser deposition
The solid solution of the ferroelectric relaxor (NaBiTiO with BaTiO, (1-x) NBT-x BT (NBT-BT) shows a
morphotropic phase boundary with enhanced properties at x = 0.06-0.07. We
have prepared targets of (1-x) NBT-x BT with x = 0.06 by solid state
reaction and sintering at 1200 C, up to a final relative density of
97.8%. Films from these targets have been deposited on MgO substrates by
pulsed laser deposition, in different substrate temperature and heating rate
conditions. First results obtained from structural, AFM and electrical
characterization are reported. The obtained films are polycrystalline
perovskite with a slight (100) orientation. High relative dielectric
constant, of about 1300, have been obtained
