AF4‐to‐SAXS: expanded characterization of nanoparticles and proteins at the P12 BioSAXS beamline

Journal of Synchrotron Radiation, EarlyView.
By coupling asymmetrical‐flow field‐flow fractionation to small‐angle X‐ray scattering (AF4–SAXS), we enable precise, size‐resolved analysis of polydisperse samples. Our automated AF4–SAXS system at the EMBL P12 beamline streamlines workflows, making advanced characterization accessible to both novice and experienced users, with principles adaptable to

Direct derivation of anisotropic atomic displacement parameters from molecular dynamics simulations in extended solids with substitutional disorder using a neural network potential

Acta Crystallographica Section A, EarlyView.
Direct derivation of anisotropic atomic displacement parameters is possible using molecular dynamics simulations of supercells at finite temperature.Atomic displacement parameters (ADPs) are crystallographic information describing the statistical distribution of atoms around an atom site.

Discounted Optimal Stopping for Maxima in Diffusion Models with Finite Horizon [PDF]

We present a solution to some discounted optimal stopping problem for the maximum of a geometric Brownian motion on a finite time interval. The method of proof is based on reducing the initial optimal stopping problem with the continuation region ...

Complete metamorphosis promotes morphological and functional diversity in Caudata

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Metamorphosis, a common and spectacular developmental process, involves major phenotypic changes often linked to environmental transitions. Understanding how these changes affect morphological evolution is crucial for examining metamorphosis's evolutionary impacts.
