Twisted MoS2 Bilayers as Functional Elements in Memtransistors: Hysteresis, Optical Signatures, and Photocurrent Kinetics

open access: yesAdvanced Electronic Materials, Volume 12, Issue 17, 7 September 2026.
ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...

Subdifferentials of sublinear operators and selectors

open access: yes, 1992
Sublinear operators and selectors of multivalued mappings have been considered in the paper. As a result the subdifferentiability of arbitrary compact sublinear operators has been proved as well as the subdifferentiability of continuous sublinear ...

Real‐Time Biomass Estimation in High‐Density Yeast Fermentations Using Soft Sensor Modeling

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 9, Page 2389-2405, September 2026.
Accurate biomass measurements, both offline and online, are essential to improve prediction and control in yeast fermentation. This study develops regression‐based predictive models to correlate offline measurements (Dry Cell Weight and OD600 from a spectrophotometer) with online OD860 probe signals to provide accurate real‐time biomass estimations and

Parvalbumin interneurons in Alzheimer's disease: Physiological insights and pathophysiological mechanisms

open access: yesJournal of Cell Communication and Signaling, Volume 20, Issue 3, September 2026.
Physiological and Pathological Alterations in PV+ Neurons: Under physiological conditions, PV+ interneurons exhibit fast‐spiking properties and generate gamma oscillations at the cost of high energy consumption. In AD, PV+ neurons display abnormalities in ion channels, dendrites, neurotransmission, energy metabolism, and neural oscillations, ultimately

Slope Aspect Modulates Alpine Meadow Spatial Homogeneity Through Niche Differences, Not Fitness Differences

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study examines the role of slope aspect in mediating the spatial homogeneity of alpine meadow communities on the Qinghai‐Tibetan Plateau through the lens of modern coexistence theory. We found that slope aspect strongly mediated community homogeneity by altering niche differences, but not fitness differences, with this effect being significant ...

Fractional List Packing for Layered Graphs

open access: yesJournal of Graph Theory, Volume 113, Issue 1, Page 19-37, September 2026.
ABSTRACT The fractional list packing number χ ℓ • ( G ) of a graph G is a graph invariant that has recently arisen from the study of disjoint list‐colourings. It measures how large the lists of a list‐assignment L : V ( G ) → 2 N need to be to ensure the existence of a “perfectly balanced” probability distribution on proper L‐colourings, that is, such ...

Existence and multiplicity of positive solutions to systems of nonlinear Hammerstein integral equations

open access: yesElectronic Journal of Differential Equations, 2019
This article studies the existence and multiplicity of component-wise positive solutions for systems of nonlinear Hammerstein integral equations. In this system one nonlinear term is uniformly superlinear or uniformly sublinear, and the other is ...

An Introduction to Stochastic Deep Learning

open access: yesWIREs Computational Statistics, Volume 18, Issue 3, September 2026.
The stochastic neural network, formulated as a composition of linear, logistic, and nonlinear regression modules, serves both as a deep learning model and as an analytical device for studying the properties of deep learning. It broadens deep learning beyond prediction‐oriented function approximation into a richer framework for statistical inference ...
