What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Simulation-based multiobjective optimization of tail beam control strategy for top-coal caving

Advances in Mechanical Engineering
In longwall top-coal caving, the motion control strategy of the hydraulic support tail beam directly affects the caving performance. To reduce gangue admixture and improve the efficiency of top-coal discharge, this study proposes an offline parameter ...

Do High Temperatures Affect Firm Demography? Evidence From Italy

Business Strategy and the Environment, EarlyView.
ABSTRACT This study analyses the impact of high temperatures and heat stress on Italian firm demography during 2009–2022. Combining provincial‐firm‐level data with a high‐resolution multidecadal meteorological dataset, we investigate whether high temperatures—absolute and anomalous—affect firm entry and exit rates.

Investigating mechanical and geometrical effects of joints on minimum caving span in mass caving method

International Journal of Mining and Geo-Engineering, 2023
This paper investigates the effect of jointed rock mass properties on the Minimum Required Caving Span (MRCS) in the block caving method using numeric and heuristic approaches. To do so, the effects of five parameters of jointed rock mass, namely joint set number, joint spacing, joint inclination angle, joint surface friction angle, and undercut depth ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.
