Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Don't You Know That You're Toxic? How Influencer‐Driven Misinformation Fuels Online Toxicity

Psychology &Marketing, EarlyView.
ABSTRACT Research on misinformation has focused on message content and cognitive bias, overlooking how source type shapes toxic engagement. This study addresses that gap by showing that influencer‐driven misinformation does not merely increase toxicity: it reconfigures its nature and persistence through relational and social influence mechanisms ...

Advances and Current Progress of Dopant Engineering on All‐Inorganic Halide Perovskites Toward High‐Performance Scintillating Materials

MetalMat, EarlyView.
This review provides the latest advancement on lead‐free all‐inorganic perovskites, covering fundamental aspects, emerging synthetic routes, and scintillation properties. We highlight the dopant engineering strategy to favor the formation and efficient radiative recombination of self‐trapped excitons and the future development direction for the next ...

New Opportunities For the Integration of Artificial Intelligence With Materials Science: From Large Language Models to Embodied Large Models

Materials Genome Engineering Advances, EarlyView.
This review first introduces the diversified applications of large language models in materials discovery. Subsequently, the evolution of autonomous experimentation platforms empowered by large language models is analyzed. Finally, four key future research interests are proposed to develop embodied large models for driving autonomous experimentation ...

Solute Segregation in Polycrystalline Aluminum From Hybrid Monte Carlo and Molecular Dynamics Simulations With a Unified Neuroevolution Potential

Materials Genome Engineering Advances, EarlyView.
We develop an efficient GPU implementation of the hybrid Monte Carlo and molecular dynamics method in the GPUMD package and use it, in combination with the neuroevolution potential, to simulate the segregation of 15 solutes in polycrystalline Al, revealing distinct segregation patterns and the mechanisms of solute strengthening and embrittlement ...

Adversarial Contention Resolution Games

Proceedings of the Thirty-Second International Joint Conference on Artificial Intelligence, 2023
We study contention resolution (CR) on a shared channel modelled as a game with selfish players. There are n agents and the adversary chooses some k smaller than n of them as players. Each participating player in a CR game has a packet to transmit. A transmission is successful if it is performed as the only one at a round.

Contention resolution with message deadlines

Distributed Computing, 2020
In the contention-resolution problem, multiple players contend for access to a shared resource. Contention resolution is used in wireless networks, where messages must be transmitted on a shared communication channel. When two or more messages are transmitted at the same time, a collision occurs, and none of the transmissions succeed.

Stochastic Contention Resolution With Short Delays

SIAM Journal on Computing, 1995
Summary: We study contention resolution protocols under a stochastic model of continuous request generation from a set of contenders. The performance of such a protocol is characterized by two parameters: the maximum arrival rate for which the protocol is stable and the expected delay of a request from arrival to service.

CORD: contention resolution by delay lines

IEEE Journal on Selected Areas in Communications, 1996
The implementation of optical packet-switched networks requires that the problems of resource contention, signalling and local and global synchronization be resolved. A possible optical solution to resource contention is based on the use of switching matrices suitably connected with optical delay lines.
