Atomic‐Level Dual‐Cation Engineering Enables High‐Performance Na4VMn(PO4)3 Cathodes for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐cation site engineering unlocks stable and fast sodium storage in Na4VMn(PO4)3 cathodes. Li+ at Na2 suppresses Jahn‐Teller distortion, while K+ at Na1 expands ion channels, enabling synchronized V/Mn redox and quasi‐single‐phase kinetics. This atomic‐level strategy achieves ultralong cycling stability, high‐rate capability, and full cell viability

Recomposable Layered Metasurfaces for Wavelength‐Multiplexed Optical Encryption via Modular Diffractive Deep Neural Networks

open access: yesAdvanced Functional Materials, EarlyView.
Modular diffractive deep neural network metasurfaces encode and reconstruct holograms across layer combinations and wavelengths, enabling secure, multifunctional operation. Each layer acts independently yet composes jointly, yielding up to m(2N −1) channels for m wavelengths and N layers.

Cooperative Behaviour

2021
This chapter tackles the cooperative behavior of animals. Cooperation occurs when an individual's behavior benefits the fitness of another individual and evolves in part because of the benefit. Many cooperative behaviors reduce the fitness of the individual performing the behavior.

Attraction and cooperative behavior [PDF]

open access: possible, 2012
Being good-looking seems to generate substantial benefits in many social interactions, making the "beauty premium" a not to be underrated economic factor. This paper investigates how physical attractiveness enables people to generate these benefits in the case of cooperation, using field data from a modified one-shot prisoner's dilemma played in a high-

Cooperative Behavior in Dyads

Journal of Conflict Resolution, 1974
It was hypothesized that cooperative behavior would decrease over time in an interaction between cooperatively oriented and competitively oriented persons. Pairs of male undergraduates, in which one S was induced to assume a competitive orientation and the other a cooperative one, played thirty trials of a Prisoner's Dilemma game.

Systemic behavior of cooperative search algorithms

Parallel Computing, 2004
Abstract Distributed computer systems may be used in various ways to find good solutions to difficult combinatorial optimization problems. An interesting approach consists in executing concurrently different search methods that exchange information gathered in previously explored regions of the solution space.

Cooperative Firm Behavior

2015
The innovation process of a firm gets fuelled by internal and external sources. First, scientists and engineers of a firm explore new combinations and exploit new knowledge for the development of new products and processes. This is linked to RD Chesbrough, 2003). Second, knowledge and new ideas can be accessed externally through links to other actors.

Cooperation-Based Behavior Design

2002
Robot soccer explores such a research topic that multiple agents work together in a Real-time, Cooperative and Adversarial (RCA) environment to achieve specific objectives. It requires that each agent can not only deal with situations individually, but also present cooperation with its teammates.
