How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Analysis and design of a capsule landing system and surface vehicle control system for Mars exploration [PDF]

open access: yes
A number of problems related to unmanned exploration of planets or other extraterrestrial bodies with Mars as a case in point were investigated. The design and evaluation of a prototype rover concept with emphasis on mobility, maneuverability, stability,

Leading the Loop: Anchor‐Led Orchestration in Nascent Circular Ecosystems—A Qualitative Case Study

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The transition towards a circular economy necessitates coordinated, systemic change across value chains. Yet the role of anchor firms in initiating and orchestrating nascent circular ecosystems remains underexplored. Using an inductive, qualitative single‐case design, we analyse a German mid‐sized entrepreneurial firm, drawing on 21 interviews

The Tree of Life Synagogue Attack: A Terrorist Radicalization Assessment Protocol‐18 Examination of Pre‐Attack Warnings and Post‐Attack Contagion and Copycat Effects

open access: yesBehavioral Sciences &the Law, EarlyView.
ABSTRACT This is a retrospective case study of an antisemitic lone actor terrorist who completed the deadliest attack against the Jewish community in American history. The analysis through the lens of the Terrorist Radicalization Assessment Protocol (TRAP‐18) finds that 72% of the warning indicators were present, including four proximal warning ...

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

open access: yesChemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

The Future of Foundation Machine Learning Potentials and DFT in Homogeneous Catalysis: Competition or Synergy?

open access: yesChemistry – A European Journal, EarlyView.
Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

Simplified Strategy for Trajectory Tracking Application of a Passive Suspension Rover-Type Mobile Robot

open access: yesMachines
In the present work, based on an approximate modelling of a rover-type robot and a proportional control law, a simplified trajectory tracking strategy for a passive suspension rover-type mobile robot was developed.

Tokenism or Catalytic? Exploring Board Gender Diversity Through the Lens of SDG 9 Outcomes in the EU Context

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores the relationship between Executive gender diversity (EGD) and the achievement of Sustainable Development Goal 9 (SDG 9—Industry, Innovation, and Infrastructure) in the European Union. It investigates whether female representation in corporate governance contributes to innovation‐driven sustainability.
