Abstract Stem cell therapies have emerged as potential therapeutics of interest for many central nervous system diseases, including stroke, epilepsy, neurodegenerative diseases, and traumatic brain injury. Preclinical models are required to evaluate the migration of transplanted stem cells to various areas of the brain, monitor graft survival to ...

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Estimation of Equilibrium Scour Depth Around Abutments by Artificial Intelligence
The estimation of clear water scour depth around bridge piers directly affects the stability and safety of bridge structures. An accurate estimation of equilibrium scour depth (Dse) around bridge abutments is crucial for ensuring structural stability.

We used a calibrated individual‐based model to explore the reintroduction of pine martens to Britain and whether woodland creation can be targeted to improve pine marten dispersal. We find that the reintroduction programme is successful into the near future, even if it does not appear to form a single unified population.

High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...

Numerical Investigation of Local Scour Around Bridge Pile-Group Foundations Under Steady Flows
Local scour around pile-group foundations is a predominant cause of hydraulic instability in bridge engineering. This study employs a fully coupled three-dimensional computational fluid dynamics model to investigate local scour around a 2 × 2 inline pile

Using 16 flume experiments and 2D modeling, we show that large‐wood flow resistance is not a fixed property of wood porosity but varies systematically with flow condition, blockage and most strongly sediment‐shaped bed topography. The drag coefficient and Manning's n are interchangeable, but calibration is essential where scour occurs.

Modelling Flood‐Induced Riparian Vegetation Disturbance and Hydro‐Morphodynamic Feedbacks
A process‐based framework links flood‐induced vegetation disturbance to hydro‐morphodynamic feedback by separating mechanical failure from postfailure outcomes, explaining spatial distribution patterns of washout, burial and localized embankment erosion during the 2019 Chikuma River flood.
