3dcon: tomogram denoising by deconvolution

open access: yesActa Crystallographica Section D, Volume 82, Issue 11, Page 1240-1250, November 2026.
An open‐source entropy‐regularized deconvolution workflow is presented for denoising tomographic reconstructions from cryo‐electron microscopy.Cryo‐electron tomography is an expanding technology for the study of macromolecules, viruses and cells.

Potentiation effects of the positive allosteric modulator PTC‐174 on NMDA receptors in neonatal male rat substantia nigra dopaminergic neurons

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 21, Page 6481-6500, November 2026.
Abstract Background and Purpose Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC‐174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits.

Selector form of Weaver's conjecture and frame sparsification

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 5, November 2026.
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

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
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

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
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

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 37, October 5, 2026.
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 ...
