High‐Resolution Satellite Imagery Reveals Landscape‐Scale Benthic Habitat Changes in a Turbid Coral Reef

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
High‐resolution satellite imagery and landscape metrics revealed a 77% decline in coral‐dominated habitats at Abrolhos Bank between 2010 and 2024, accompanied by macroalgal and zoanthid expansion. Spatial reorganisation indicates increasing fragmentation, homogenisation and loss of reef structural complexity.

Ionic Liquids at the Interface With the Transition Metal Dichalcogenide MoS2: Effect of the Chemical Structure on Induced Charge Carrier Density

open access: yesSmall, EarlyView.
Ionic liquid gating of MoS2 channels using [EMIM][TFSI] or [EMIM][BF4] can lead to different carrier densities. [TFSI]‐based systems exhibit steeper voltage decay (compared to [BF4]‐based systems) meaning the potential drops more rapidly across the electric double layer, indicating stronger local electric fields and more efficient charge accumulation ...

Maturation of seeds of Caesalpinia echinata Lam. (Brazilwood), an endangered leguminous tree from the Brazilian Atlantic Forest

open access: yesBrazilian Archives of Biology and Technology, 2005
The present work describes changes during the maturation process of seeds of Caesalpinia echinata Lam. Individual flowers were tagged in the day of their anthesis and the pods were collected directly from the branches from 32 to 65 days after flowering ...

Low‐Voltage Pulsed GMA‐AM Application for Controlling Heat Input and Improving Deposition Quality of 309LSi Multilayered Structures

open access: yessteel research international, EarlyView.
This manuscript presents a study on the effects of parameter control of low‐voltage pulsed‐GMA‐AM application for producing 309LSi multilayered build‐ups, which can simultaneously lead to reduced heat input up to 32.1%, enable pulsed‐spray transfer, provide stable depositing conditions and preserve dimensional consistency, favoring fabrication of a 114‐

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...
