Differential Progression of Neuroinflammation in Patients with Isolated Rapid‐Eye‐Movement Sleep Behavior Disorder

Movement Disorders, EarlyView.
Abstract Background Neuroinflammation, measured using [11C](R)‐PK11195 positron emission tomography (PET), has been reported in isolated rapid‐eye‐movement sleep behavior disorder (iRBD), but its temporal progression is unknown. Objective The aim was to assess longitudinal progression of neuroinflammation in iRBD patients and its relationship with ...

Efficient analysis and representation of geophysical processes using localized spherical basis functions

, 2009
While many geological and geophysical processes such as the melting of icecaps, the magnetic expression of bodies emplaced in the Earth's crust, or the surface displacement remaining after large earthquakes are spatially localized, many of these ...

A Geometric Interpretation for the Algebraic Properties of Second‐Order Ordinary Differential Equations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6912-6917, April 2025.
ABSTRACT Nowadays, a substantial portion of investigations concerning the symmetry analysis of differential equations predominantly adhere to a framework comprising the following key procedures: (i) the derivation of symmetries, (ii) the determination of an optimal system, (iii) the utilization of these symmetries to construct invariants or ...

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Optimized J2 Recovery for Multi‐Decadal Geophysical Studies

Geophysical Research Letters
The time history of the Earth's dynamic oblateness, or J2, is a unique climate data record, with its estimation from satellite laser ranging (SLR) tracking data beginning in 1976.

Moisture inversions in the central Arctic: Product assessment and long‐wave radiative effect

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the integrated water vapour and the vertical distribution of water vapour of state‐of‐the‐art reanalyses, weather forecast models, and ground‐ and space‐based remote‐sensing products in the central Arctic. A particular focus lies on the representation of humidity inversions and the quantification of the long‐wave radiative effect ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

On the compatibility of single‐scan terrestrial LiDAR with digital photogrammetry and field inventory metrics of vegetation structure in forest and agroforestry landscapes

Remote Sensing in Ecology and Conservation, EarlyView.
The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.

Climate Crisis, Human Mobility and Security Challenges in the MENA Region: Implications for Sustainable Development and Regional Stability

Sustainable Development, EarlyView.
ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...
