More pumas (Puma concolor) does not change perceptions: The mismatched response of ranchers to the presence of a top carnivore

People and Nature, EarlyView.
Abstract Human‐wildlife conflicts (HWCs) are one of the most critical conservation challenges worldwide. Large carnivores are frequently at the centre of these conflicts because of the perceived and real threats they pose to livestock and human safety.

Deep learning‐based H&E‐derived risk scores in colorectal cancer: associations with tumour morphology, biology, and predicted drug response

The Journal of Pathology, EarlyView.
Abstract Over recent years, several deep learning (DL) models have been presented to predict colorectal cancer (CRC) patient survival directly from haematoxylin and eosin (H&E)‐stained routine whole‐slide images (WSIs). Unlike traditional studies that rely on manually defined histopathological features, weakly supervised DL allows training directly on ...

A data-driven droop control strategy for reactive power sharing and stability enhancement in islanded AC microgrids

International Journal of Electrical Power & Energy Systems
In islanded microgrids, distributed generation (DG) units employing conventional droop control often exhibit significant mismatches in reactive power sharing. This issue primarily arises from the mismatches in line impedances. These inaccuracies not only

Multi-segment droop control and optimal parameter setting strategy of wind turbine for frequency regulation

International Journal of Electrical Power & Energy Systems
Traditionally, virtual inertia is used as the control strategy for wind turbines when participating in frequency regulation. However, it has inherent defects in measurement error amplification due to the frequency differential.

Data informed performance assessment and structural health monitoring for existing and historical concrete structures

Structural Concrete, EarlyView.
Abstract Our generation inherits this cultural heritage of historic material and historic reinforced concrete structures and thus bears a certain responsibility to preserve these historic buildings with the help of the new technologies of lifetime management, conservation concepts and the new digitalization as well as the emerging safety concepts of ...

Punching shear in flat slab systems – Experimental quantification of unconsidered system influences

Structural Concrete, EarlyView.
Abstract Due to the demand for slender and functional buildings, flat slabs are a frequently used load‐bearing element in buildings. However, the concentrated load introduction at the slab‐column connection is often the governing detail in design due to punching shear failure.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...
