Global Diversification Rates of Ferns Across Spatial and Climatic Gradients

open access: yesAdvanced Science, EarlyView.
Diversification rates of fern genera across the phylogeny. Abstract Geographic patterns of diversity in any group of plants are the result of the interplay of environmental conditions and the evolutionary dynamics of the respective plant group. Here, the geographic distribution of current mean diversification rates (MDR) is explored at the genus level ...

Unification modulo presburger arithmetic and other decidable theories

open access: yesRevista Colombiana de Computación, 2001
We present a general uni cation algorithm modulo Presburger Arithmetic for a re- stricted class of modularly speci ed theories where function symbols of the target theory have non arithmetic codomain sorts.

Degradable and Recyclable 3D‐Printed Pheromones Delivery System Reinforced by Metal Coordination Cross‐Linking for Efficient Pest Trapping

open access: yesAdvanced Science, EarlyView.
This study presents a 3D‐printed carrier for the slow release of insect pheromones. Reinforced by lignosulfonate and Fe³⁺ coordination in a cellulose acetate matrix, it enables sustained release for up to six weeks with remarkable trapping efficacy. Featuring soil degradability and recyclable re‐printing capability, this carrier provides a sustainable ...

Recruitment of the premotor cortex during arithmetic operations by the monkey

open access: yesScientific Reports
Arithmetic operations are complex mental processes rooted in the abstract concept of numerosity. Despite the significance, the neural architecture responsible for these operations has remained largely uncharted. In this study, we explored the presence of

TRIM56 Aggravates Cerebral Ischemia‐Reperfusion Injury via Inhibiting KLF4‐Activated Ferroptosis Signaling

open access: yesAdvanced Science, EarlyView.
This study reveals that the E3 ubiquitin ligase TRIM56 exacerbates neuronal ferroptosis and brain damage by mediating K48‐linked ubiquitination and degradation of KLF4, leading to suppression of the xCT/GSH/GPX4 axis. Targeting TRIM56 alleviates cerebral ischemia‐reperfusion injury in vivo and in vitro, highlighting its therapeutic potential.

A Dynamic DNA Nano‐Antioxidant Targeting Galectin‐3 Attenuates Liver Fibrosis via Reducing Macrophage Oxidative Stress

open access: yesAdvanced Science, EarlyView.
This study developed a dynamic DNA nano‐antioxidant (DDN) for Galectin‐3 siRNA delivery, specifically targeting hepatic macrophages to suppress ROS‐driven fibrosis. DDN enhanced hepatic accumulation, restored NRF2 signaling, and attenuated oxidative stress, collagen deposition, and fibrotic progression in a CCl4‐induced cirrhosis model, demonstrating ...
