Game Tree Search-based Impulsive Orbital Pursuit–Evasion Game with Limited Actions

Space: Science & Technology
This paper focuses on the impulsive orbital pursuit–evasion game (OPEG) with limited action sets for the pursuer and evader. Initially, a mathematical model is developed by combining game theory and orbital dynamics, forming a finite-round impulsive OPEG

Pursuer’s Control Strategy for Orbital Pursuit-Evasion-Defense Game with Continuous Low Thrust Propulsion

Applied Sciences, 2019
This paper studies the orbital pursuit-evasion-defense problem with the continuous low thrust propulsion. A control strategy for the pursuer is proposed based on the fuzzy comprehensive evaluation and the differential game. First, the system is described

Active Target Defense Differential Game with a Fast Defender

, 2015
This paper addresses the active target defense differential game where an Attacker missile pursues a Target aircraft. A Defender missile is fired by the Target's wingman in order to intercept the Attacker before it reaches the aircraft.

CDK4/6 Inhibition Induces CD8+ T Cell Antitumor Immunity via MIF‐Induced Functional Orchestration of Tumor‐Associated Macrophages

Advanced Science, EarlyView.
CDK4/6 inhibition promotes CD8+ T cell expansion through tumor‐macrophage crosstalk by activating HIF‐1α and enhancing MIF‐CD44/CD74 signaling. This reprograms TAMs to boost MHC‐I antigen presentation, and CDK4/6 inhibitor‐trained M1 TAM supernatant therapy synergizes with low‐dose PD‐1 blockade to restore antitumor immunity.

An improved lion strategy for the lion and man problem

, 2017
In this paper, a novel lion strategy for David Gale's lion and man problem is proposed. The devised approach enhances a popular strategy proposed by Sgall, which relies on the computation of a suitable "center".

DMAP1 Deficiency Suppresses Lung Cancer Progression by Destabilizing Replication Fork and Activating IFN Signaling‐Mediated Anti‐tumor Immunity

Advanced Science, EarlyView.
Lung cancer remains the leading cause of cancer‐related death. We investigated the role of the epigenetic regulator DMAP1 in NSCLC and found that its loss induces replication stress and DNA damage. This in turn activates type I IFN signaling via the cGAS–STING pathway and transcriptional ISG de‐repression, enhancing anti‐tumor immune responses ...

Cooperative Pursuit-Evasion Games With a Flat Sphere Condition

IEEE Open Journal of Control Systems
In planar pursuit-evasion differential games considering a faster pursuer and a slower evader, the interception points resulting from equilibrium strategies lie on the Apollonius circle.

Cooperative Hunting Strategy with a Superior Evader Based on Differential Game

Complexity, 2022
This paper considers a pursuit-evasion game with multiple pursuers and a superior evader. A novel cooperative pursuit strategy is proposed to capture a faster evader while maintaining a formation. First, the initial states including position distribution

Pursuit Evasion: The Herding Noncooperative Dynamic Game-The Stochastic Model

, 2001
This article proposes a solution to the herding problem, a class of pursuit evasion problem in a stochastic framework. The problem involves a pursuer agent trying to herd a stochastically moving evader agent into a pen. The problem is stated in terms
