Tuning Interface Electronic Properties via Chiral Two‐Dimensional Metal‐Organic Frameworks

Small Structures, Volume 6, Issue 12, December 2025.
Structural symmetries are crucial for dictating the electronic properties of materials. Numerical methods with low‐temperature scanning probe microscopy techniques are combined to quantitatively address how different chiral phases of a two‐dimensional (2D) metal‐organic framework uniquely scatter a 2D electron gas and alter its band structure.

Approximation of Daily AMS‐02 Spectra With Machine Learning Methods

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

High‐caloric intake rescues early symptomatic AD‐induced hippocampal neurovascular coupling deficits

Alzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION Alzheimer's disease (AD) involves progressive hippocampal dysfunction and atrophy. Obesity, common in AD patients, is a known dementia risk factor. Studying their interaction is difficult in humans due to AD's slow progression. Experimental AD models comorbid with obesity are needed for translational insights.

The role of the Weibel instability at the reconnection jet front in relativistic pair plasma reconnection

, 2008
The role of the Weibel instability is investigated for the first time in the context of the large-scale magnetic reconnection problem. A late-time evolution of magnetic reconnection in relativistic pair plasmas is demonstrated by particle-in-cell (PIC ...

Integration of the atmospheric fluctuations in a dual-field optical interferometer: the short exposure regime

, 2003
Spatial phase-referencing in dual-field optical interferometry is reconsidered. Our analysis is based on the 2-sample variance of the differential phase between target and reference star.

Multi-set space-time shift-keying with reduced detection complexity

, 2016
In this treatise, we propose a novel Multi-Set Space-Time Shift Keying (MS-STSK) technique, where the source bits are conveyed over two components, namely by activating one out of MQ dispersion matrices of Space-Time Shift Keying (STSK) and M Antenna ...
