Noncommutative Gauge Theory on Fuzzy Four-Sphere and Matrix Model
, 2002 We study a noncommutative gauge theory on a fuzzy four-sphere. The idea is to use a matrix model with a fifth-rank Chern-Simons term and to expand matrices around the fuzzy four-sphere which corresponds to a classical solution of this model.

Finite sphere packing and sphere covering [PDF]
Discrete & Computational Geometry, 1989 A basic problem of finite packing and covering is to determine, for a given number ofk unit balls in Euclideand-spaceEd, (1) the minimal volume of all convex bodies into which thek balls can be packed and (2) the maximal volume of all convex bodies which can be covered by thek balls. In the sausage conjectures by L. Fejes Toth and J. M.

The power of microRNA regulation—insights into immunity and metabolism
FEBS Letters, EarlyView.MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

Identification of novel small molecule inhibitors of ETS transcription factors
FEBS Letters, EarlyView.ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six

Diffeomorphisms of a product of spheres and embedded spheres
Topology and its Applications, 2002 AbstractLet M be the product of n copies of the p-dimensional sphere Sp with p⩾1 and n⩾2. In this paper we completely determine those automorphisms of Hp(M;Z)≅Zn which can be realized by a diffeomorphism of M. As an application, we completely classify smoothly embedded p-dimensional spheres in M up to diffeomorphisms of M.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Casimir interaction between a sphere and a grating
, 2015 We derive the explicit expression for the Casimir energy between a sphere and a 1D grating, in terms of the sphere and grating reflection matrices, and valid for arbitrary materials, sphere radius, and grating geometric parameters.

Public Sphere as Democratic Sphere
Issues in Social Science, 2018 Political public space is more conflicted and stressed. Process of black-balling other actors is dominant here. Other civilian public spaces mean mutual learning and opinion improvement. These two spaces try to affect each other. Civilian public spaces try to affect political public space with political discourses.
