From torsion theories to closure operators and factorization systems [PDF]
Categories and General Algebraic Structures with Applications, 2020 Torsion theories are here extended to categories equipped with an ideal of 'null morphisms', or equivalently a full subcategory of 'null objects'. Instances of this extension include closure operators viewed as generalised torsion theories in a 'category

Isomorphism of Compactifications of Vector Bundles Moduli: Nonreduced Moduli
Моделирование и анализ информационных систем, 2015 We continue the study of the compactification of the moduli scheme for Gieseker-semistable vector bundles on a nonsingular irreducible projective algebraic surface S with polarization L, by locally free sheaves.

On an Isomorphism of Compactifications of Moduli Scheme of Vector Bundles
Моделирование и анализ информационных систем, 2015 A morphism of the reduced Gieseker - Maruyama moduli functor (of semistable coherent torsion-free sheaves) on the surface to the reduced moduli functor of admissible semistable pairs with the same Hilbert polynomial, is constructed. It is shown that main

Design and biomechanical study of slide-poking external fixator for hip fracture
Journal of International Medical Research, 2020 Background Femoral head collapse and coxa vara lead to internal fixator failure in elderly patients with hip fracture. External fixator application is an optimal choice; however, the existing methods have many disadvantages.
