Foundations of Ghost Stability

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

Exploring Cordycepin as a Neuroprotective Agent in Huntington's Disease: In Vitro and In Vivo Insights

Pharmacology Research &Perspectives, Volume 13, Issue 2, April 2025.
Cordycepin from Cordyceps sinensis has shown certain neuroprotective effects and alleviated the formation of mHTT aggregates in different HD cell and transgenic mouse models. ABSTRACT Huntington's disease (HD) is a challenging neurodegenerative disorder linked to Huntingtin (HTT) gene mutation, lacking an effective cure despite numerous therapeutic ...

Fire, Fuel, and Climate Interactions in Temperate Climates

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract Temperate regions around the world are experiencing longer fire weather seasons, yet trends in burned area have been inconsistent between regions. Reasons for differences in fire patterns can be difficult to determine due to variable vegetation types, land use patterns, fuel conditions, and human influences on fire ignition and suppression ...

Quantifying Fire‐Driven Dust Emissions Using a Global Aerosol Model

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.
Abstract Vegetation fires have become increasingly recognized as a potential entrainment mechanism for mineral dust. However, the global importance of this emission pathway remains largely unknown. Based on previous LES investigations, we developed a parameterization that relates the dust emission potential of wildfires to observational data of the ...

The Role of Lithology on Concentration‐Discharge Relationships and Carbon Export in Two Adjacent Headwater Catchments

Water Resources Research, Volume 61, Issue 4, April 2025.
Abstract Headwater catchments have strong impacts on downstream waterways, near‐shore ecosystems, and the quality of water available for growing human populations. Thus, understanding how water and solutes are exported through these upland landscapes is critically important. A growing body of literature highlights the interaction of topography, climate,

InstaMap: instant‐NGP for cryo‐EM density maps

Acta Crystallographica Section D, Volume 81, Issue 4, Page 147-169, April 2025.
Cryo‐EM density‐map inference, with fixed pose and contrast transfer function, using a multi‐resolution hash‐encoding framework called instant‐NGP, is described, together with its extension to heterogeneity inference by bending space with a per‐image vector field.Despite the parallels between problems in computer vision and cryo‐electron microscopy ...

Actin Binding to the BAR Domain and Arf GAP Activity of ASAP1 Coordinately Control Actin Stress Fibers and Focal Adhesions

Biology of the Cell, Volume 117, Issue 4, April 2025.
Dynamic assembly of higher order actin cytoskeletal structures is fundamental to metazoan biology. While the regulation of actin filaments and the constituents of higher order actin structures have been described, the mechanism underlying the regulated assembly of the higher order actin structures, such as actin stress fibers, is still being discovered.
