Resonant X‐Ray Diffraction of Conjugated Polymers at the Selenium K‐Edge

Macromolecular Rapid Communications, Volume 47, Issue 9, 5 May 2026.
Analogous to isomorphous replacement used in X‐ray crystallography studies of proteins, substituting sulfur for selenium in conjugated polymers enables resonant diffraction studies of molecular packing down to the length scale of π‐‐π stacking. Two selenium‐containing polymers are studied with a comparison made between sulfur K‐edge and selenium K‐edge

When Proximity Falls Short: Inequalities in Commuting and Accessibility by Public Transport in Santiago, Chile

Geographical Analysis, Volume 58, Issue 2, April 2026.
ABSTRACT Traditional measures of urban accessibility often rely on static models or survey data. However, location information from mobile networks enables large‐scale, dynamic analyses of how people navigate cities. In this study, we employ eXtended Detail Records (XDRs) from mobile phone activity to analyze commuting patterns and accessibility ...

Financial Time Series Uncertainty: A Review of Probabilistic AI Applications

Journal of Economic Surveys, Volume 40, Issue 2, Page 915-953, April 2026.
ABSTRACT Probabilistic machine learning models offer a distinct advantage over traditional deterministic approaches by quantifying both epistemic uncertainty (stemming from limited data or model knowledge) and aleatoric uncertainty (due to inherent randomness in the data), along with full distributional forecasts.

S3RL: Enhancing Spatial Single‐Cell Transcriptomics With Separable Representation Learning

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Separable Spatial Representation Learning (S3RL) is introduced to enhance the reconstruction of spatial transcriptomic landscapes by disentangling spatial structure and gene expression semantics. By integrating multimodal inputs with graph‐based representation learning and hyperspherical prototype modeling, S3RL enables high‐fidelity spatial domain ...

Synaptic Behavior in SnSe2 Field‐Effect Transistors Induced by Surface Oxide and Trap Dynamics

Advanced Electronic Materials, Volume 12, Issue 5, 9 March 2026.
Multilayer SnSe2 field‐effect transistors display gate‐tunable optoelectronic plasticity driven by interfacial trap states. Persistent photocurrent is reversibly tuned between short‐ and long‐term memory through gate bias and pulsed control. The devices emulate synaptic functions such as potentiation, modulation, and cumulative learning, establishing ...

Muscle MRI and Muscle Ultrasound Applications in MND/ALS: Academic Insights and Clinical Opportunities

European Journal of Neurology, Volume 33, Issue 3, March 2026.
ABSTRACT Background There is an unmet need for the clinically relevant ALS biomarkers to facilitate an accurate diagnosis in suspected cases, monitor disease progression and evaluate response to therapy in clinical trials. While the MND/ALS literature is dominated by innovative brain studies, motor disability in ALS is primarily driven by neurogenic ...

Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Recently, Stephens et al. (2023), https://doi.org/10.1029/2022ja031066 utilized a data mining (DM) algorithm, applied to 26 years of magnetospheric magnetometer observations coupled with a flexible formulation of the magnetospheric magnetic field, to reconstruct the global configuration of the magnetotail when the Magnetospheric MultiScale ...

Comprehensive analysis of structure–property–shielding relationships in Pr2O3-modified tellurite glass systems

Scientific Reports
This work investigated the structural, thermal, mechanical, and shielding characteristics of a tellurite-based glass series with the composition 60TeO2–12.5Nb2O5–12.5ZnO–(15–x)LiF–xPr2O3, where x ranged from 0.5 to 5.0 mol%. The novelty of this study lay
