Collaborative Control of UAV Swarms for Target Capture Based on Intelligent Control Theory

open access: yesMathematics
Real-time dynamic capture of a single moving target is one of the most crucial and representative tasks in UAV capture problems. This paper proposes a multi-UAV real-time dynamic capture strategy based on a differential game model to address this ...

Multicentric tracking of multiple agents by anterior cingulate cortex during pursuit and evasion

open access: yesNature Communications, 2021
Pursuit or evasion requires world-centric and agent-centric representation to coordinate navigation and motor control. The dorsal anterior cingulate cortex, which communicates bi-directionally with both the hippocampal complex and premotor areas serve a ...

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

open access: yes, 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

NKCC1: A key regulator of glioblastoma progression

open access: yesMolecular Oncology, EarlyView.
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Interception Domain Approach to Orbital Multi-Player “Encirclement-Capture” Games: Theoretical Foundations and Solutions

open access: yesAerospace
In recent years, with the development of micro-satellite clusters and large-scale satellite constellations, the likelihood of multiple spacecraft engaging in orbital pursuit–evasion games has increased.

Optimal feedback strategies for pursuit-evasion and interception in a plane [PDF]

open access: yes
Variable-speed pursuit-evasion and interception for two aircraft moving in a horizontal plane are analyzed in terms of a coordinate frame fixed in the plane at termination. Each participant's optimal motion can be represented by extremal trajectory maps.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Evasion Differential Games in the Space of Square Summable Sequences

open access: yesGames
In this article, we consider simple-motion pursuit–evasion differential games in the Hilbert space of square summable sequences. We show that when the players have the same dynamic capabilities, evasion is possible under some assumptions about the ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Orbital Pursuit–Evasion–Defense Linear-Quadratic Differential Game

open access: yesAerospace
To find superior guidance strategies for preventing possible interception threats from space debris, out-of-control satellites, etc., this paper investigates an orbital pursuit–evasion–defense game problem with three players called the pursuer, the ...
