Anisotropic compact star model: a brief study via embedding

European Physical Journal C: Particles and Fields, 2019
In present article a new model of compact star is obtained in the framework of general relativity which does not suffer from any kinds of singularity. We assume that the underlying fluid distribution is anisotropic in nature along with a new form for the

Remarks on Smooth Real-Compactness for Sikorski Spaces

Demonstratio Mathematica, 2014
It is known that every Sikorski space with the countably generated differential structure is smoothly real-compact. It means that every homomorphism from its differential structure, which forms a ring of smooth real-valued functions into the ring of real

Sobolev Spaces on Locally Compact Abelian Groups: Compact Embeddings and Local Spaces

Journal of Function Spaces, 2014
We continue our research on Sobolev spaces on locally compact abelian (LCA) groups motivated by our work on equations with infinitely many derivatives of interest for string theory and cosmology.

Synset2Node: A new synset embedding based upon graph embeddings

Intelligent Systems with Applications, 2023
Due to the advances made in recent years, embedding methods caused a significant increase in the accuracy of text or graph processing methods. Embedding methods exhibit a compact vector representation of the basic elements (words, synsets, nodes,..) of ...

Brézis-Wainger Inequality on Riemannian Manifolds

Journal of Inequalities and Applications, 2008
The Brézis-Wainger inequality on a compact Riemannian manifold without boundary is shown. For this purpose, the Moser-Trudinger inequality and the Sobolev embedding theorem are applied.

AUTOMORPHISM GROUPS OF MAPS, SURFACES AND SMARANDACHE GEOMETRIES [PDF]

, 2005
A combinatorial map is a connected topological graph cellularly embedded in a surface. As a linking of combinatorial configuration with the classical mathematics, it fascinates more and more mathematician’s interesting.

Embedding theorems for locally compact Markov shifts

, 2005
We characterize when a lower entropy locally compact subshift S embeds into a locally compact mixing Markov shift T. As in the compact case (when T is a shift of finite type) the existence of an embedding depends on S only through its periodic orbit ...

An embedding theorem for proper n-types [PDF]

, 1992
This paper is centred around an embedding theorem for the proper n-homotopy category at infinity of Σ-compact simplicial complexes into the n-homotopy category of prospaces. There is a corresponding global version.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.
