Stiffness‐Activated Stellate Cells Drive Pancreatic Cancer Liver Colonization via GMFG‐TNS4 Signaling

open access: yesAdvanced Science, EarlyView.
Fibrotic liver stiffness activates hepatic stellate cells through Piezo1‐dependent calcium influx and ER stress, promoting EV‐associated GMFG release. Delivered GMFG engages TNS4 in pancreatic cancer cells, triggering FAK/AKT signaling, adhesion, and fatty acid synthesis.

Experience‐Dependent Reorganization of Hippocampal CA3 Neuronal Ensembles Associates With Memory Generalization

open access: yesAdvanced Science, EarlyView.
Mice can transfer the learned rule of spatial working memory to guide similar but novel tasks. Hippocampal CA3 populational activity dynamically reorganize during memory generalization, shifting from task‐specific to generalized coding over testing days. Sparse yet redundant neural representations of CA3 enable rule transfer and cognitive map formation,

Molecular Dynamics‐Guided Sterol Engineering of mRNA‐Lipid Nanoparticles Reprograms Biodistribution and Enhances Spleen‐Selective Immunity

open access: yesAdvanced Science, EarlyView.
Sterol engineering enables precise control of mRNA lipid nanoparticles by tuning membrane organization. Replacing cholesterol with bile acid‐derived sterols redirects protein expression from the liver to the spleen. Notably, CA‐20 LNP enhances antigen‐specific immune responses while exhibiting a favorable safety profile, highlighting sterols as a ...

Mallard Use of Hen HousesTM in Eastern Ontario

open access: yesAvian Conservation and Ecology, 2006
Nesting structures for ground-nesting waterfowl may be an effective technique for increasing nesting success in regions in which nest success is below the 15% threshold needed to maintain a stable population.

Maternal health status correlates with nest success of leatherback sea turtles (Dermochelys coriacea) from Florida. [PDF]

open access: yesPLoS ONE, 2012
Of the seven sea turtle species, the critically endangered leatherback sea turtle (Dermochelys coriacea) exhibits the lowest and most variable nest success (i.e., hatching success and emergence success) for reasons that remain largely unknown.

Patterns of nesting and nest success in an evergreen forest in Southeast Asia

open access: yesEmu - Austral Ornithology, 2019
Southeast Asian forest birds are threatened by the highest rate of tropical deforestation globally, but conservation efforts regionally have very limited information from which to make policy and management plans. To provide baseline data on nesting and nest success for forest birds from an intact forest, we monitored 1506 nests of 54 species during ...

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

TURKEY NESTING SUCCESS OM A FLORIDA STUDY AREA

open access: yesWildlife Society Bulletin, 1980
Nesting success of wild turkeys (Meleagris gallopavo) was measured for 108 nests of radio‐tracked hens on a Florida study area during an 8‐year period.

Olive ridley sea turtle hatching success as a function of the microbial abundance in nest sand at Ostional, Costa Rica.

open access: yesPLoS ONE, 2015
Several studies have suggested that significant embryo mortality is caused by microbes, while high microbial loads are generated by the decomposition of eggs broken by later nesting turtles.
