Study of Free‐Space Optical Quantum Network: Review and Prospectives

open access: yesAdvanced Science, EarlyView.
Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.

A Triple‐Nanoparticle System for Controlled Graphene Nanosheet Stacking: Enabling K/Na‐Ion Battery Anodes with Ultra‐Fast Charging Exceeding Petroleum Vehicle Refueling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Large‐ion (K, Na) battery systems mitigate uneven global lithium distribution, while their ability to attain recharge time shorter than refueling would remove the final barrier for secondary batteries to replace petroleum vehicles. However, their large‐ion chemistry makes ultra‐fast charging an even significant challenge.

A groupoid approach to the study of fuzzy topological spaces

open access: yesApplied General Topology
The definition of the complement of a fuzzy subset is algebraic in nature and when it is used in the context of fuzzy topological spaces it does not share any similarity with the usual property of topological spaces that the complement of an open subset ...

On some paracompactness-type properties of fuzzy topological spaces

open access: yes, 2019
The aim of this paper is to study some paracompactness-type properties for fuzzy topological spaces. We prove that these properties are good extensions of others defined by A.V. Arkhangel’skii (and studied by S.A.

An Overview on intuitionistic fuzzy topological spaces [PDF]

open access: yes, 2021
We present a brief overview some fundamental results on the intuitionistic fuzzy topological spaces, and give some introductory results about fuzzy open set, fuzzy closed set, fuzzy neighborhood, fuzzy interior set, fuzzy continuity, fuzzy compactness ...

Triple‐Mode Ferroelectric Thin‐Film Transistor for Hybrid Electrical–Optical Reservoir Computing

open access: yesAdvanced Science, EarlyView.
A triple‐mode ferroelectric thin‐film transistor is developed by integrating Si3N4/HZO/IGZO layers to realize three independent memory modes: electric long‐term, electric short‐term, and optical short‐term. This single‐device architecture functions as both a reservoir and readout layer, achieving 92.43% MNIST accuracy. It offers a fully hardware‐based,

Wθg-Closed and Wδg-Closed in [0,1]-Topological Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
We investigate various classes of generalized closed fuzzy sets in [0,1]-topological spaces, namely, Wθg-closed fuzzy sets and Wδg-closed fuzzy sets.

On Set-Texture Spaces and Degree-Texture Spaces

open access: yesWasit Journal for Pure Sciences, 2022
A general theory of fuzzy sets was described employing texture spaces. This work aimed to introduce two concepts in texture theory, namely set-texture and degree-texture spaces using topological spaces and new properties.

Decoding Spatial Heterogeneity and Multi‐Omics Regulation with Hierarchical Graph Learning

open access: yesAdvanced Science, EarlyView.
ABSTRACT Recent advances in spatial multi‐omics technologies have enabled the simultaneous profiling of multiple molecular layers within the same tissue slice, providing unprecedented opportunities to investigate tissue spatial organization. However, most existing computational methods identify spatial domains in a purely data‐driven manner, rarely ...
