Vine-Twining Inclusion Behavior of Amylose towards Hydrophobic Polyester, Poly(β-propiolactone), in Glucan Phosphorylase-Catalyzed Enzymatic Polymerization

Life, 2023
This study investigates inclusion behavior of amylose towards, poly(β-propiolactone) (PPL), that is a hydrophobic polyester, via the vine-twining process in glucan phosphorylase (GP, isolated from thermophilic bacteria, Aquifex aeolicus VF5)-catalyzed ...

On certain classes of almost product structures.

Michigan Mathematical Journal, 1983
The paper studies the geometrical meaning of certain conditions on plane fields that were imposed by the reviewer for obtaining different classes of almost-product manifolds [Rend. Mat. Appl., VII. Ser. 3, 577--592 (1983; Zbl 0538.53045) (see the following review)]. Three of the conditions are of transversal nature in the sense of Haefliger structures.

Four-Dimensional CR Submanifolds of the Homogeneous Nearly Kähler Product Manifold ${\mathbb{S}}^3\times {\mathbb{S}}^3$

Mathematics
This article presents results on four-dimensional CR submanifolds of the homogeneous nearly Kähler product manifold S3×S3. In the research of CR submanifolds of S3×S3, the most important role in the classification is played by the action of the almost ...

The de Rham Cohomology Classes of Hemi-Slant Submanifolds in Locally Product Riemannian Manifolds

Mathematics
This paper aims to discuss the de Rham cohomology of hemi-slant submanifolds in locally product Riemannian manifolds. The integrability and geodesical invariance conditions of the distributions derived from the definition of a hemi-slant submanifold are ...
