Cohomology Theories on Compact and Locally Compact Spaces

open access: yesRevista Matemática Iberoamericana, 1986
The aim of this paper is to give an expository account of the uniqueness theorem for cohomology theories on the category of locally compact Hausdorff spaces and proper continuous functions. The uniqueness theorem can be applied to give a proof of the known result that the Chern character induces an isomorphism K(X)\(\otimes {\mathbb{Q}}\cong \check H ...

Cohomology of Compact Locally Symmetric Spaces [PDF]

open access: yesCompositio Mathematica, 2001
We obtain a necessary condition for a cohomology class on a compact locally symmetric space S (Γ)=Γ\ X (a quotient of a symmetric space X of the non-compact type by a cocompact arithmetic subgroup Γ of isometries ...

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

The group of characters of a pseudocompact locally compact semitopological semigroup

open access: yesApplied General Topology
We prove that each semitopological semigroup has a reflection in the class of abelian cancellative semitopological semigroups. Then we use this reflection to prove that the group of characters of a locally compact pseudocompact topological semigroup with

On the Generalized Weighted Lebesgue Spaces of Locally Compact Groups

open access: yesAbstract and Applied Analysis, 2011
Let 𝐺 be a locally compact group with a fixed left Haar measure 𝜆 and Ω be a system of weights on 𝐺. In this paper, we deal with locally convex space 𝐿𝑝(𝐺,Ω) equipped with the locally convex topology generated by the family of norms (‖.‖𝑝,𝜔)𝜔∈Ω. We study

Space-Varying Coefficient Models for Brain Imaging [PDF]

open access: yes, 2005
The methodological development and the application in this paper originate from diffusion tensor imaging (DTI), a powerful nuclear magnetic resonance technique enabling diagnosis and monitoring of several diseases as well as reconstruction of neural ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

The relations between separately and jointly proprities of multi-valued mappings (in Ukrainian) [PDF]

open access: yesМатематичні Студії, 2011
We prove the following statement. Let $X$ be a topological space, $Y$ a topological $T_1$ first-countable space,$Z$ a metrizable locally compact $sigma$-compact space and $Fcolon Ximes Y o Z$ a close-valued separately continuous mapping.

Polymer Interface Enables Reversible Quasi‐Solid Sulfur Conversion in Sodium‐Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The polymer interface enables a stable quasi‐solid sulfur conversion pathway in room‐temperature Na─S batteries. The coating regulates Na+ transport, stabilizes the cathode–electrolyte interphase, and accommodates mechanical stress, suppressing electrolyte decomposition and sulfur migration, thereby improving reaction uniformity, reducing polarization,

On the Fuzzy Number Space with the Level Convergence Topology

open access: yesJournal 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 ...
