The role of absorption in 3D electron diffraction dynamical structure refinement
This work establishes the role of absorption in 3D electron diffraction dynamical refinement, where its inclusion is shown to significantly affect refinement outcomes only in high‐Z materials at thicknesses approaching ξg.The role of absorption in 3D electron diffraction is established through analytical theory, simulation and dynamical refinement.

Selector form of Weaver's conjecture and frame sparsification
Abstract We show an extension of a probabilistic result of Marcus, Spielman, and Srivastava, which resolved the Kadison–Singer problem, to block diagonal positive semidefinite random matrices. We use this result to show several selector results, which generalize their partition counterparts.

First Observation of Four‐Band Ion Cyclotron Whistlers
Abstract Ion cyclotron whistlers are frequently observed in low Earth orbit, typically formed when right‐hand polarized lightning whistlers undergo polarization reversal at crossover frequencies. In this study, we for the first time report a four‐band ion cyclotron whistler event detected by Van Allen Probe A.

Dielectric Nanoparticle Dimers on a Mirror for Enhanced Photoluminescence of Quantum Dots
Hybrid metal–dielectric nanoantennas based on nanoparticle‐on‐mirror architectures are proposed to enhance quantum dot photoluminescence. Silicon nanocylinder dimers on aluminum substrates enable simultaneous excitation enhancement and directional emission through strong light–matter interactions.

Accelerating Sustainable Epoxy Resin Development Through Bayesian Optimization and Inverse Design
Development of a machine learning framework for the optimization of the Tg of partially bio‐based epoxy resin formulations in a 13‐component design space using Bayesian optimization, active learning, random design, and inverse design. The results show that the BO effectively navigates high‐dimensional formulation spaces, and the final ML model could ...

An integral containing a Bessel Function and a Modified Bessel Function of the First Kind
Here we discuss the calculation of an integral containing the Bessel function J0(r) and the modified Bessel function of the first kind I1(r). The calculus is based on a function of J0(r), I1(r) and of their derivatives, having a Wronskian form. The method here described could be useful for training the students in the manipulation of such integrals.
