Quasi-Compactness of Operators for General Markov Chains and Finitely Additive Measures

open access: yesMathematics
We study Markov operators T, A, and T* of general Markov chains on an arbitrary measurable space. The operator, T, is defined on the Banach space of all bounded measurable functions.

Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

open access: yesAdvanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

A new two-level implicit scheme of order two in time and four in space based on half-step spline in compression approximations for unsteady 1D quasi-linear biharmonic equations

open access: yesAdvances in Difference Equations, 2018
In this article, we discuss a new two-level implicit scheme of order of accuracy two in time and four in space based on the spline in compression approximations for the numerical solution of 1D unsteady quasi-linear biharmonic equations.

Weakly Cauchy filters and quasi-uniform completeness [PDF]

open access: yes, 1999
[EN] It is well-known that the notion of a Smyth complete quasi-uniform space provides an appropriate notion of completeness to study many interesting quasi-metric spaces which appear in theoretical computer science.

Bandgap‐Engineered AlGaAs/GaAs Heterostructures for Wavelength‐Selective Dual‐Polarity Photoelectrochemistry

open access: yesAdvanced Functional Materials, EarlyView.
Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Some results over thin--thick sets in cone locally convex spaces

open access: yesFixed Point Theory and Applications, 2011
In this article, it is investigated some concepts of normed space like norming, thin-thick sets in cone locally convex spaces. It is also worked some impacts of thick sets over the uniform quasi-boundedness principles in cone locally convex spaces such ...

Mining spatial co-location patterns via γ-quasi-clique detection

open access: yesEPJ Data Science
Spatial co-location patterns (SCPs) are sets of spatial features with instances frequently co-occurring proximally in geographical space. Extracting SCPs is crucial for understanding urban space structure and function.

Multi-Criteria Calibration of a Thermo-Mechanical Model of Steel Plate Welding in Vacuum

open access: yesJournal of Manufacturing and Materials Processing
This paper proposes a procedurefor multi-criteria calibration of a thermo-mechanical model for numerical simulation of welding in the space vacuum. A finite-element model of a steel plate is created. Experimental and computational data are obtained.

Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective

open access: yesAdvanced Functional Materials, EarlyView.
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in
