Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

Biological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Joint optimization of beamforming and power allocation for DAJ‐based untrusted relay networks

ETRI Journal, 2018
Destination‐assisted jamming (DAJ) is usually used to protect confidential information against untrusted relays and eavesdroppers in wireless networks. In this paper, a DAJ‐based untrusted relay network with multiple antennas installed is presented.

Enhancing Resilience Against Jamming Attacks: A Cooperative Anti-Jamming Method Using Direction Estimation

IEEE Transactions on Communications
The inherent vulnerability of wireless communication necessitates strategies to enhance its security, particularly in the face of jamming attacks. This paper uses the collaborations of multiple sensing nodes (SNs) in the wireless network to present a cooperative anti-jamming approach (CAJ) designed to neutralize the impact of jamming attacks.

Can Hybrid Organisations Solve the Paradox of the Triple Bottom Line, and Does It Need Solving?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how B Corp certification enables hybrid organisations to integrate competing institutional logics of market and social purpose. Through a two‐stage qualitative design combining cross‐sector interviews with B Corps and an in‐depth case study, with a total of 30 participants, we analyse how certification supports hybrid ...

Eco‐Innovation: Drivers and Obstacles for Agriculture Firms in a Developing Country

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainable agriculture is becoming increasingly vital for food security and economic growth, particularly as the agricultural sector grapples with challenges posed by climate change. This study, grounded in the environmental innovation theory, resource‐based view, and dynamic capabilities approach, uses logistic and multinomial logistic ...

Rising Strong: Cultivating Resilience in Edible City Entrepreneurship. Insights Into the Landscape of Urban Food Initiatives

Business Strategy and the Environment, EarlyView.
ABSTRACT In response to growing global challenges, this study explores how social entrepreneurship within the Edible City movement contributes to building resilient, sustainable, and equitable urban food systems. Drawing on semistructured interviews with over 70 stakeholders across five cities—Berlin, Andernach, Oslo, Rotterdam, and Havana—we ...

Legitimate Monitoring via Cooperative Relay and Proactive Jamming

IEEE Access, 2019
With the development of communication technologies, many suspicious communication technologies have also been greatly improved. Therefore, one single monitor may not be able to afford in a monitoring process. In this paper, we propose a wireless communication system using two legitimate monitors for cooperative monitoring program, in which the signals ...

Mitochondria and the Actin Cytoskeleton in Neurodegeneration

Cytoskeleton, EarlyView.
ABSTRACT Mitochondrial dysfunction and cytoskeletal disorganization are widely recognized hallmarks of neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS).

Research on adaptive scheduling strategy of cooperative jamming resources for the anti-netted radar system

AIP Advances
Jamming resource allocation is an important step in implementing cooperative jamming. Traditional jamming resource allocation considers only the reduction of enemy radar detection performance but ignores the problem of mutual interference in the ...
