Steric‐Setup Effects on US East Coast Sea‐Level Change

Abstract The extent to which coastal sea levels co‐vary with open‐ocean variability is explored through evaluation of a balanced dynamics framework relating sea level with pressure, density, and velocity along the continental shelf and slope seafloor. Using high‐resolution region...

NKCC1 coordinates SPAK-PP1 signalling to regulate KCC2 membrane stability and seizure susceptibility.

Chloride homeostasis, and thereby the efficacy of chloride-permeable GABAA receptor signaling, depends on the dynamic balance between NKCC1 (Na+-K+-2Cl- cotransporter 1) and KCC2 (K+-Cl- cotransporter 2), which respectively mediate chloride influx and extrusion to tightly control...

Targeting the Complement C1 Proteases Using Camelid-Derived Single Domain Antibodies: Production, Characterization and Possible Application for Tissue/Fluid Analysis

Background. The complement C1r and C1s proteases initiate the classical complement pathway within the C1 complex, but emerging evidence points to additional roles in tissues, including cell-intrinsic functions linked to cancer and connective tissue disorders. Few tools are availa...

Dynamics of charge fluctuations in nanocapacitors: Effects of salt concentration and electrode metallicity from Brownian dynamics

Electric double-layer capacitors (EDLCs) rely on the dynamical response of confined electrolytes to store and release charge, yet the interplay between ion transport, electrostatic interactions, and electrode metallicity remains poorly understood at the nanoscale. In this work, w...

Decline of chaperone-mediated autophagy in aging impairs macrophage clearance of senescent cells

Autophagy dysfunction and senescence are established drivers of aging, but their potential interaction remains poorly understood. Here we show that age-related decline of chaperone-mediated autophagy (CMA), a pathway for selective lysosomal protein degradation, changes senescent...

Mass-lumped mixed finite elements methods and the abstract gradient scheme framework for elliptic problems

We provide a general framework for second-order elliptic problems, which includes a variety of boundary conditions. We show how one can apply mass-lumped mixed finite element to this problem, and we provide sufficient conditions for the convergence of such a method. In particular...

Ultrafast Micrometric Laser Structuring of Polymer Surfaces for Highly Organized Skeletal Muscle Tissue Modeling

ABSTRACT Engineered surface topographies have proven to be an efficient method to replicate in vitro the architecture of highly organized tissues by controlling the spatial arrangement of cells. In this work, we studied the ability to guide muscle cell development using femtoseco...

Wild-type and mutated ß-catenin differently repress RND3/RHOE expression in hepatocellular carcinoma

Tumor development and progression are mainly driven by oncogenic mutations but are also regulated by physical factors. Through its structural and transcriptional functions, ß-catenin is a key factor that acts on both aspects to promote liver tumorigenesis, leading to hepatocellul...

Universal random matrix behavior of a Fermionic quantum gas

Since its initial use by Wigner in describing heavy atom spectra, random matrix theory (RMT) has found applications and revealed universal laws in diverse physical contexts, from quantum field theory to disordered systems and wireless communications. A particularly compelling app...

Relapsed/refractory WAldenström macroglobulinemia patients treated by VEnetoclax with or without anti-CD20 antibody: WAVE a retrospective study of the French CLL/WM group (FILO)

Abstract Recently venetoclax (Ven) monotherapy showed promising efficacy for relapsed/refractory (R/R) Waldenström macroglobulinemia (WM), a population with significant medical unmet need. We report the efficacy and safety of Ven associated or not with anti-CD20 therapy, in a rea...

International Modified Delphi Consensus on Assessment and Management of Covert Brain Infarction

BackgroundCovert brain infarction (CBI) is a frequent incidental neuroradiological finding increasingly recognized as clinically relevant due to its association with stroke, cognitive decline, and other adverse outcomes. However, substantial uncertainty remains regarding its opti...

Design, Synthesis and Biophysical Characterisation of CPP‐PNA Conjugates for Targeting Oncogenic microRNA‐221

Peptide nucleic acids (PNAs) are a promising platform targeting disease-associated microRNAs due to their high binding affinity, excellent sequence specificity and resistance to enzymatic degradation. However, their therapeutic application is often limited by inefficient cellular...

Quantum propagation for Berezin–Toeplitz operators

We describe the asymptotic behaviour of the quantum propagator generated by a Berezin–Toeplitz operator with real-valued principal symbol. We also give precise asymptotics for smoothed spectral projectors associated with the operator in the autonomous case; this leads us to intro...

The DESI Y1 RR Lyrae Catalog. II. The Metallicity Dependency of Pulsational Properties, the Shape of the RR Lyrae Instability Strip, and Metal Rich RR Lyrae

Abstract RR Lyrae stars (RRLs) are valuable probes of both Milky Way assembly and stellar-evolution physics. Using a sample 6240 RRLs obtained in the first year of the Dark Energy Spectroscopic Instrument (DESI) survey, we investigate the metallicity of RRLs and its correlation w...

A Decomposition Approach for Large Virtual Network Embedding

ABSTRACT Virtual Network Embedding (VNE) is the core combinatorial problem of Network Slicing, a 5G technology which enables telecommunication operators to propose diverse service‐dedicated virtual networks, embedded onto a common substrate network. VNE asks for a minimum‐cost ma...

A new input convex neural network with application to options pricing

We introduce a new class of neural networks designed to be convex functions of their inputs, leveraging the principle that any convex function can be represented as the supremum of the affine functions it dominates. These neural networks, inherently convex with respect to their i...

The DESI Y1 RR Lyrae Catalog. I. Empirical Modeling of the Cyclic Variation of Spectroscopic Properties and a Chemodynamical Analysis of the Outer Halo

Abstract We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6240 RRLs out to ∼120 kpc from the Galactic center and over 12,000 individual epochs with homogeneous...

Largest eigenvalue statistics of wavefront shaping in complex scattering media

Abstract In wavefront shaping, light, sound, and other waves are focused through complex scattering media onto one or more target positions, and the resulting intensity enhancement is quantified by the enhancement factor. While reproducible enhancement is crucial in experiments,...

Medication use during pregnancy in Europe and North America: a systematic review

To describe the mean number of medications used as well as the prevalence of medication use throughout pregnancy in Europe and North America, with a focus on use by trimester, type of medication, and use of harmful medications. A systematic review was performed searching MEDLINE,...

Supramolecular Janus Nanocylinders: Solvent-Induced Hydrogen-Bond Modulation Yields Structures under Thermodynamic Equilibrium

Abstract Janus nanocylinders (JNCs) are anisotropic, non-centrosymmetric colloids composed of two different faces, making them attractive for advanced functional materials. However, their nanometric dimensions and pronounced anisotropy complexify their preparation. Recently, a ve...
