Local Compactness in Fuzzy Convergence Spaces

Journal of Mathematical Analysis and Applications, 2002
AbstractTwo notions of local precompactness in the realm of fuzzy convergence spaces are investigated. It is shown that the property of local precompactness possesses a “good extension.” Moreover, for each given fuzzy convergence space, there exists a coarsest locally precompact space which is finer than the original space.

Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

On the Fuzzy Number Space with the Level Convergence Topology

Journal of Function Spaces and Applications, 2012
We characterize compact sets of 𝔼1 endowed with the level convergence topology τℓ. We also describe the completion (𝔼1̂,𝒰̂) of 𝔼1 with respect to its natural uniformity, that is, the pointwise uniformity 𝒰, and show other topological properties of 𝔼1 ...

Compact sheaves on a locally compact space

Proceedings of the American Mathematical Society
Let X X be a hypercomplete locally compact Hausdorff space and let C \mathcal C be a compactly generated stable ∞ \infty -category. We describe the compact objects in the ∞ \infty -category of C \mathcal C -valued sheaves S

On the Regularity of Measures on Locally Compact Spaces [PDF]

Proceedings of the American Mathematical Society, 1972
The purpose of this paper is to present the two following theorems: (1) Every Baire measure on the a-algebra Xa generated by the compact Tj subsets of a paracompact, locally compact space is outer regular; (2) in a paracompact, locally compact space, any Baire measure on -L can be extended to an outer regular Borel measure on the a-algebra generated by

3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

Localic completion of uniform spaces [PDF]

Logical Methods in Computer Science, 2017
We extend the notion of localic completion of generalised metric spaces by Steven Vickers to the setting of generalised uniform spaces. A generalised uniform space (gus) is a set X equipped with a family of generalised metrics on X, where a generalised ...

Gaussian‐Sigmoid Reinforcement Transistors: Resolving Exploration‐Exploitation Trade‐Off Through Gate Voltage‐Controlled Activation Functions

Advanced Functional Materials, EarlyView.
The characteristics of a vertical n–p–i–p heterostructure transistor device, which exhibits a voltage‐tunable transition between Gaussian and sigmoid functions, are investigated. The mixed state of the transfer curve enables the utilization of both exploitation and exploration, improving computational performance in reinforcement learning tasks ...

On the Chabauty space of locally compact abelian groups

, 2010
This paper contains several results about the Chabauty space of a general locally compact abelian group. Notably, we determine its topological dimension, we characterize when it is totally disconnected or connected; we characterize isolated points ...

Diffusion on locally compact ultrametric spaces

Expositiones Mathematicae, 2004
AbstractWe consider an ultrametric space with sufficiently many isometries and we construct a class of diffusion processes on the space as appropriate limits of discrete processes on the (open and closed) balls of the space. We show, using a version of the Lévy Khintchine formula adapted to this general context, that our construction includes all ...
