Q-Learning Based Physical-Layer Secure Game Against Multiagent Attacks

open access: yesIEEE Access, 2019
In this paper, we consider a Q-learning-based power allocation strategy for a secure physical-layer system under dynamic radio environments. In such a system, the transmitter sends the information to the receiver threatened by M(M ≥ 2) intelligent

Exact Algorithms for Solving Stochastic Games [PDF]

open access: yes, 2012
Shapley's discounted stochastic games, Everett's recursive games and Gillette's undiscounted stochastic games are classical models of game theory describing two-player zero-sum games of potentially infinite duration.

Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

open access: yesAdvanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Antagonistic One-To-N Stochastic Duel Game

open access: yesMathematics, 2020
This paper is dealing with a multiple person game model under the antagonistic duel type setup. The unique multiple person duel game with the one-shooting-to-kill-all condition is analytically solved and the explicit formulas are obtained to determine ...

Existence of Nash Equilibrium Points for Markovian Nonzero-sum Stochastic Differential Games with Unbounded Coefficients

open access: yes, 2014
This paper is related to nonzero-sum stochastic differential games in the Markovian framework. We show existence of a Nash equilibrium point for the game when the drift is no longer bounded and only satisfies a linear growth condition.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

A Cross-Layer Routing Protocol Based on Quasi-Cooperative Multi-Agent Learning for Multi-Hop Cognitive Radio Networks

open access: yesSensors, 2019
Transmission latency minimization and energy efficiency improvement are two main challenges in multi-hop Cognitive Radio Networks (CRN), where the knowledge of topology and spectrum statistics are hard to obtain.

A maximum principle for fully coupled controlled forward–backward stochastic difference systems of mean-field type

open access: yesAdvances in Difference Equations, 2020
In this paper, we consider the optimal control problem for fully coupled forward–backward stochastic difference equations of mean-field type under weak convexity assumption.

Reactive Strategies: An Inch of Memory, a Mile of Equilibria

open access: yesGames, 2021
We explore how an incremental change in complexity of strategies (“an inch of memory”) in repeated interactions influences the sets of Nash equilibrium (NE) strategy and payoff profiles. For this, we introduce the two most basic setups of repeated games,
