The Role of Dendritic Spines in Water Exchange Measurements With Diffusion MRI: Time‐Dependent Single Diffusion Encoding MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Geometric exchange between dendritic spines and shafts is often neglected, yet it exhibits the same signature as permeative exchange, biasing NEXI/SMEX measurements. We propose two models: an extended three‐compartment Kärger model that resolves spine–shaft exchange explicitly, and a coarse‐grained Kärger model that absorbs spines into an effective ...

Probing the Structure and Thermoresponsive Behavior of Multicompartment Micelles by Combined Solution‐ and Solid‐State NMR Spectroscopy

open access: yesAnalysis &Sensing, Volume 6, Issue 5, September 2026.
Combined solution‐ and solid‐state NMR spectroscopy is used to probe chain rearrangements in thermoresponsive PNIPAM‐based micelles. We show how core composition affects micellar dynamics and chain mobility across the LCST transition of PNIPAM.

Protein‐Stabilized Copper Nanoclusters for Microbial Inhibition‐Enabled Fresh Produce Preservation and Pesticide Removal

open access: yescMat, Volume 3, Issue 3, September 2026.
Biocompatible bovine serum albumin‐stabilized copper nanoclusters (Cu@BSA NCs) were engineered to integrate potent antimicrobial activity with efficient pesticide adsorption. The dual mechanism, involving Cu species/ROS‐mediated microbial inactivation and BSA‐facilitated pesticide capture, enables simultaneous extension of fresh produce shelf‐life by ≥

Scalable and Controlled Production of Microalgae‐derived Extracellular Vesicles Using a Differential Tangential Flow Filtration Protocol

open access: yesJournal of Extracellular Biology, Volume 5, Issue 9, September 2026.
This work presents a robust project design for the scalable production of extracellular vesicles, focusing on nanoalgosomes derived from microalgae. Careful parameter optimization within a filtration‐based process ensures consistent isolation while preserving the structural and functional integrity of the vesicles.

Spectrum Sensing Based on Higher Order Cumulants and Kurtosis Statistics Tests in Cognitive Radio [PDF]

open access: yesRadioengineering, 2019
In this paper, new algorithms for spectrum sensing in cognitive radio based on higher order cumulants and kurtosis are proposed. The cumulants represent statistical signal processing based on pattern recognition for signals of different structure, and ...

Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 9, Page 1603-1616, September 2026.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Buffer and salt dependent reassembly pathways of Myxococcus xanthus encapsulin

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Protein cages that adopt multiple assembly states provide tractable systems for probing the mechanisms that govern icosahedral shell formation. The Myxococcus xanthus encapsulin shell protein assembles into either a T = 1 shell (60 subunits) or a T = 3 shell (180 subunits), making it an ideal model to investigate how solution conditions bias ...

Easy all-order cumulants

open access: yes, 2016
12 pagesWe present a systematic procedure for analyzing cumulants to arbitrary order in the context of heavy-ion collisions. It generalizes and improves existing procedures in many respects.

On learning higher-order cumulants in diffusion models

open access: yesMachine Learning: Science and Technology
To analyse how diffusion models learn correlations beyond Gaussian ones, we study the behaviour of higher-order cumulants, or connected n -point functions, under both the forward and backward process.
