Thermal noise lowers the accuracy of rotationally invariant harmonics of diffusion MRI data and their robustness to experimental variations

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 204-219, January 2026.
Abstract Purpose Rotational invariants (RIs) are at the root of many dMRI applications. Among others, they are presented as a sensible way of reducing the dimensionality of biophysical models. While thermal noise impact on diffusion metrics has been well studied, little is known on its effect on spherical harmonics‐based RI (RISH) features and derived ...

Electron Channeling Contrast Imaging for the Characterization of Dislocations in III−V Thin Films on Silicon (001)

physica status solidi (a), Volume 223, Issue 2, January 2026.
Defect characterization plays a crucial role in semiconductor research, yet the development of fast, cheap, and nondestructive tools remains challenging. This work applies electron channeling contrast imaging (ECCI) to III–V thin films on silicon, examining beam parameters and diffraction conditions.

A GIS‐Based Framework for Modeling Hospital Accessibility in Spain Using Open and Collaborative Data

Geographical Analysis, Volume 58, Issue 1, January 2026.
ABSTRACT This study analyzes hospital accessibility in Spain at the census section level from 2010 to 2024. Using open data and open‐source tools, a replicable geospatial method was developed to estimate travel times and distances to the nearest hospital by car and on foot. Over 500,000 origin–destination pairs were analyzed, combining census centroids,

Public perception of Ghana's Free Senior High School policy: A north–south comparative analysis

Review of Policy Research, Volume 43, Issue 1, January 2026.
Abstract Ghana's Free Senior High School (SHS) policy, implemented in 2017, aims to increase access to secondary education, promote equity, enhance educational outcomes, and foster human capital development. This study examines public perception of the Free SHS policy, focusing on the variations between the northern and southern regions of Ghana and ...

A Coarse‐to‐Fine 3D LiDAR Localization With Deep Local Features for Long‐Term Robot Navigation in Large Environments

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
The location of a robot is a key aspect in the field of mobile robotics. This problem is particularly complex when the initial pose of the robot is unknown. In order to find a solution, it is necessary to perform a global localization. In this paper, we propose a method that addresses this problem using a coarse‐to‐fine solution.

Unveiling the Direct Air Capture and Transformation to Formate Under Mild Conditions

ChemSusChem, Volume 18, Issue 21, Novemebr 4, 2025.
Aiming to decrease CO2 emissions and proposing new green and sustainable strategies and technologies, in this research we have conducted direct air capture and transformation into formate using a sequential process. In the first step, we absorbed CO2 into an ionic liquid and then transformed into formate by using mild conditions.

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1394-1403, November 2025.
Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration
