Banach–Mazur Distance Between Convex Quadrangles
It is proved that the Banach-Mazur distance between arbitrary two convex quadrangles is at most 2. The distance equals 2 if and only if the pair of these quadrangles is a parallelogram and a triangle.

Phase retrieval for characteristic functions of convex bodies and reconstruction from covariograms [PDF]
We propose strongly consistent algorithms for reconstructing the characteristic function 1_K of an unknown convex body K in R^n from possibly noisy measurements of the modulus of its Fourier transform \hat{1_K}.

A parallel ADMM-based convex clustering method
Convex clustering has received recently an increased interest as a valuable method for unsupervised learning. Unlike conventional clustering methods such as k-means, its formulation corresponds to solving a convex optimization problem and hence ...

Continuity of the maximum-entropy inference: Convex geometry and numerical ranges approach [PDF]
We study the continuity of an abstract generalization of the maximum-entropy inference - a maximizer. It is defined as a right-inverse of a linear map restricted to a convex body which uniquely maximizes on each fiber of the linear map a continuous ...

Caenorhinus lobanovi, a new species of the tribe Deporaini (Coleoptera: Rhynchitidae) from Laos [PDF]
A new species, Caenorhinus (Flavodeporaus) lobanovi sp. n. from Central Laos is described and illustrated. This new species differs from Caenorhinus (Flavodeporaus) guskovae Legalov, 2021 from Laos in the unicoloured body (in C.

Coloring translates and homothets of a convex body [PDF]
We obtain improved upper bounds and new lower bounds on the chromatic number as a linear function of the clique number, for the intersection graphs (and their complements) of finite families of translates and homothets of a convex body in $\RR^n$.Comment:

The Heat Transfer Problem in a Non-Convex Body—A New Procedure for Constructing Solutions
The subject of this work is the coupled steady-state conduction-radiation-convection heat transfer phenomenon in a non-convex blackbody, which is represented by a second-order partial differential equation (representing the heat conduction inside the ...
