The ellipsoid method redux

, 2023
We reconsider the ellipsoid method for linear inequalities. Using the ellipsoid representation of Burrell and Todd, we show the method can be viewed as coordinate descent on the volume of an enclosing ellipsoid, or on a potential function, or on both.

Assessment of Globularity of Protein Structures via Minimum Volume Ellipsoids and Voxel-Based Atom Representation

Crystals, 2021
A computer algorithm for assessment of globularity of protein structures is presented. By enclosing the input protein in a minimum volume ellipsoid (MVEE) and calculating a profile measuring how voxelized space within this shape (cubes on a uniform grid)

Three Ellipsoids for External Approximation of the Half-Ball

Кібернетика та комп'ютерні технології
Introduction. Ellipsoids that approximate the half-ball in Rn (n≥2) and their volume is smaller than the volume of the ball can be used to construct algorithms for solving the problem of minimization of a convex (smooth or non-smooth) function, the ...

Topological monodromy as an obstruction to Hamiltonization of nonholonomic systems: pro or contra? [PDF]

, 2014
The phenomenon of a topological monodromy in integrable Hamiltonian and nonholonomic systems is discussed. An efficient method for computing and visualizing the monodromy is developed.

A systematic numerical study of the tidal instability in a rotating triaxial ellipsoid [PDF]

, 2010
The full non-linear evolution of the tidal instability is studied numerically in an ellipsoidal fluid domain relevant for planetary cores applications.

Polynomial-time Computation of Exact Correlated Equilibrium in Compact Games [PDF]

, 2010
In a landmark paper, Papadimitriou and Roughgarden described a polynomial-time algorithm ("Ellipsoid Against Hope") for computing sample correlated equilibria of concisely-represented games.

Affinely Invariant Matching Methods with Ellipsoidal Distributions

The Annals of Statistics, 1992
Consider the treated and control populations of size \(N_ t\) and \(N_ c\) respectively and \(X\) a set of matched variables recorded on all \(N_ t+N_ c\) units. Due to cost considerations, outcomes and additional covariates are recorded for matched subsamples of sizes \(n_ t\leq N_ t\) and \(n_ c\leq N_ c\) chosen such that the distributions of \(X ...

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Improved Assessment of Globularity of Protein Structures and the Ellipsoid Profile of the Biological Assemblies from the PDB

Biomolecules, 2023
In this paper, we present an update to the ellipsoid profile algorithm (EP), a simple technique for the measurement of the globularity of protein structures without the calculation of molecular surfaces.
