Cholesterol loss enhances TrkB signaling in hippocampal neurons aging in vitro [PDF]

open access: yes, 2008
Binding of the neurotrophin brain-derived neurotrophic factor (BDNF) to the TrkB receptor is a major survival mechanism during embryonic development. In the aged brain, however, BDNF levels are low, suggesting that if TrkB is to play a role in survival ...

Vulnerable but not equal: Mountain lakes exhibit heterogeneous patterns of phytoplankton responses to climate change

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 5, Page 712-723, September 2025.
Abstract While climate change affects the phytoplankton biodiversity at both local and global scales, predicting phytoplankton community responses to warming is impaired by their polyphyletic complexity. High mountain lakes are highly vulnerable systems, partly due to their limited biodiversity, and forecasting their ecological trajectories is a key ...

Recent Advances in Tracer‐Aided Mixing Modeling of Water in the Critical Zone

open access: yesReviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract Safeguarding water resources for society and ecosystems requires a comprehensive understanding of hydrological fluxes within the Critical Zone, Earth's living skin where the atmosphere, hydrosphere, biosphere, and lithosphere meet. For decades, tracer‐aided mixing models have been used to track water flow paths through the Critical Zone ...

On New Sorting-Based Lossless Motion Estimation Algorithms

open access: yes, 2004
Block motion estimation represents a cpu-intensive task in video encoding and many fast algorithms have been developed to improve the searching and matching phases. A milestone within the lossless approach is partial distortion elimination (PDE/SpiralPDE)
