Generic Elasticity of Thermal, Underconstrained Systems.

Athermal (i.e., zero-temperature) underconstrained systems are typically floppy, but they can be rigidified by the application of external strain, which is theoretically well understood.

Spectroscopic signatures and origin of hidden order in BaMgReO.

Clarifying the underlying mechanisms that govern ordering transitions in condensed matter systems is crucial for comprehending emergent properties and phenomena. While transitions are often classified as electronically driven or lattice-driven, we present a departure from this conventional picture in the case of the double perovskite BaMgReO. Leveraging resonant and non-resonant elastic x-ray scattering techniques, we unveil the simultaneous ordering of structural distortions and charge quadrupoles at a critical temperature of T ~ 33 K.

Source apportionment of ultrafine particles in urban Europe.

There is a body of evidence that ultrafine particles (UFP, those with diameters ≤ 100 nm) might have significant impacts on health. Accordingly, identifying sources of UFP is essential to develop abatement policies. This study focuses on urban Europe, and aims at identifying sources and quantifying their contributions to particle number size distribution (PNSD) using receptor modelling (Positive Matrix Factorization, PMF), and evaluating long-term trends of these source contributions using the non-parametric Theil-Sen's method.

The journey to diagnosis of wild-type transthyretin-mediated (ATTRwt) amyloidosis: a path with multisystem involvement.

Background: Wild-type and hereditary transthyretin-mediated amyloidosis (ATTRwt and ATTRv amyloidosis, respectively) are progressive, fatal diseases with a broad range of clinical presentations and multisystem effects. Despite having a higher prevalence, ATTRwt amyloidosis is less well characterized due to its non-hereditary nature, and its relatively poorer disease awareness delays diagnosis. Understanding of its natural history has evolved in recent years, but this is largely based on physician-collected data rather than patients' reports of their own experiences.
