Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

A Biomimetic Nanoparticle System Intercepts and Degrades Thrombospondin‐1 to Restore Vascular Homeostasis After Ischemic Injury

Advanced Science, EarlyView.
TAX2‐NPs capture extracellular TSP‐1 in the injured liver and promote its macrophage‐mediated autophagic degradation. This process blocks TSP‐1/CD47 signaling, restores VEGFR2‐AKT activity, preserves endothelial function, and mitigates hepatic ischemia‐reperfusion injury.

Mean field games with congestion [PDF]

Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2018
We consider a class of systems of time dependent partial differential equations which arise in mean field type models with congestion. The systems couple a backward viscous Hamilton–Jacobi equation and a forward Kolmogorov equation both posed in (0,T) \times (\mathbb{R}^{N}/ \mathbb{Z}^{N})

When the River Runs Low: Heterogeneous Impacts of Transportation Disruptions on Local Grain Basis

Agribusiness, EarlyView.
ABSTRACT A substantial share of U.S. soybean and corn exports from the Midwest moves by barge along the Mississippi River system to export terminals in the Louisiana Gulf. Transportation costs between Midwestern grain elevators and export terminals create a wedge between prices at these locations, and shocks to these costs are partially passed on to ...

Coordination mechanisms for congestion games [PDF]

ACM SIGACT News, 2004
Recently there has been a lot of interest in problems at the intersection of Game Theory, Economics, and Computer Science. For example, there are interesting developments concerning algorithms for equilibria and cost sharing, algorithmic mechanism design, and the efficiency of systems with selfish users [25]. In this note, I will focus on the last area

Enhancing the Efficiency of Altruism and Taxes in Affine Congestion Games through Signalling

AAAI Conference on Artificial Intelligence
We address the problem of improving the worst-case efficiency of pure Nash equilibria (aka, the price of anarchy) in affine congestion games, through a novel use of signalling.

Prescribing competence: The pros and cons of different methods for assessment

British Journal of Clinical Pharmacology, EarlyView.
Evaluating a medical graduate’s competence in rational prescribing is challenging. With the aim to guide and inspire teachers, this narrative review explores different methods that can be used to assess prescribing competence. Each method has its own advantages and disadvantages, and thus a mix of different assessment methods is needed throughout the ...
