Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Evolution Characteristics of Overlying Strata Caving and Failure Under Sublevel Caving Mining: A Field Monitoring Study

GeoHazards
Dynamically grasping the scope of the caving zone and fractured zone in overlying strata is crucial for ground pressure control in sublevel caving mining.

Numerical Analysis for the Caving Characteristics of Rock Mass with Inclined Joints in Caving Mining

, 2021
In caving mining, the successful initiation and propagation of caving require one low-dip joint set. However, not every mine has a low-dip joint set. The Hemushan Iron Mine in China was taken as the engineering background, and the caving characteristics ...

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.

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 ...

Voices From the Coast: Stakeholder Participation and Perception on Creating a Marine Protected Area

Business Strategy and the Environment, EarlyView.
ABSTRACT This study explores participatory processes in the context of marine conservation, with a specific focus on recent initiatives undertaken by the Apulia region in Italy to establish a new Marine Protected Area (MPA). Employing a qualitative cross‐sectional methodology, the study investigates how local communities perceive and engage with the ...

Theoretical Investigation of the Sliding Instability and Caving Depth of Coal Wall Workface Based on the Bishop Strip Method

Advances in Civil Engineering, 2019
As mining height increases, the influence of coal wall caving on safety production becomes stronger. There is no systematic and effective method to analyse the risk of coal wall caving and its slip caving 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.
