Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

open access: yesEcography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs

open access: yesEcography, EarlyView.
Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.

Real‐world characteristics and treatment of cardiac transthyretin amyloidosis: A multicentre, observational study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1203-1216, April 2025.
The 366 patients diagnosed with transthyretin amyloidosis cardiomyopathy (ATTR‐CM) were analyzed regarding their clinical characteristics in the first year after approval of tafamidis 61 mg for ATTR‐CM in Germany. Nearly two‐thirds of the patients were in an advanced disease stage and 64% met the key criteria of the “Transthyretin Amyloidosis ...

Masked Silylenes: Controlled Generation and Reactivity Under Thermal and Equilibrium Conditions

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
This Review provides an overview of masked silylenes as bench‐stable precursors that release silylenes (R2Si:) under thermal activation or reversible equilibria. Precursor preparation, generation pathways, and characteristic reactivity are summarized, including trapping chemistry, reversible interconversions, insertion‐type processes, and small ...

Abnormal functional connectivity patterns in temporal lobe epilepsy—An international ENIGMA‐epilepsy study

open access: yesEpilepsia Open, EarlyView.
Abstract Objectives Temporal lobe epilepsy (TLE) impacts multiple brain networks. Aberrant functional connectivity has been demonstrated in resting‐state networks (RSNs) that mediate higher brain functions in TLE. This study aimed to identify the reproducible patterns of altered functional connectivity in TLE in a large, international cohort through ...

General Framework for Multi‐Degree‐of‐Freedom Stiffness Matrix Updating for Iterative Solution Algorithms in Hybrid Simulation

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Iterative solvers are advantageous for handling nonlinear structural analysis problems. The iterative solvers often require updating the stiffness matrix, which limits their application in static and pseudo‐dynamic hybrid simulations because: (1) updating the stiffness matrix of a system involving a physical specimen is challenging; (2 ...

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

open access: yesFire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.
