Small‐angle scattering studies on diverse peptide‐based nanotube and helical ribbon structures reveal distinct form and structure factors

open access: yesJournal of Applied Crystallography, EarlyView.
Peptide nanotubes have diverse structures, which can be elucidated by small‐angle scattering. Here, we discuss in detail appropriate models for form‐ and structure‐factor effects exemplified by analysis of data for several classes of peptide nanotubes.Peptide‐based nanotubes are bio‐based self‐assembled nanostructures with intriguing structural and ...

Rare dysfunctional SCN2A variants are associated with malformation of cortical development

open access: yesEpilepsia, Volume 66, Issue 3, Page 914-928, March 2025.
Abstract Objective SCN2A encodes the voltage‐gated sodium (Na+) channel α subunit NaV1.2, which is important for the generation and forward and back propagation of action potentials in neurons. Genetic variants in SCN2A are associated with a spectrum of neurodevelopmental disorders.

Properties, mechanisms, and perspectives of ultrafast laser modifications in silicate glass volume

open access: yesInternational Journal of Applied Glass Science, EarlyView.
Abstract Ultrafast laser irradiation of glass enables highly localized structural transformations within the material's bulk, unlocking diverse applications in photonics, data storage, and microfabrication. Here, we provide a concise yet comprehensive overview of the main types of femtosecond laser‐induced modifications in silica‐based glasses (Types I,

Poisson count time series

open access: yesJournal of Time Series Analysis, EarlyView.
This article reviews and compares popular methods, some old and some recent, that produce time series having Poisson marginal distributions. The article begins by narrating ways where time series with Poisson marginal distributions can be produced.

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.
