Warped product pointwise bi-slant submanifolds of locally product Riemannian manifolds [PDF]
arXiv, 2023 In this paper we introduce the concept of pointwise bi-slant submanifolds of locally product Riemannian manifolds and studied warped product pointwise bi-slant submanifolds of locally product Riemannian manifolds. We obtain some characterization results for warped products pointwise bi-slant submanifolds.

Techniques for extraction and isolation of natural products: a comprehensive review
Chinese Medicine, 2018 Natural medicines were the only option for the prevention and treatment of human diseases for thousands of years. Natural products are important sources for drug development.

, 2006 We introduce and study the toric fiber product of two ideals in polynomial rings that are homogeneous with respect to the same multigrading. Under the assumption that the set of degrees of the variables form a linearly independent set, we can explicitly ...

Finite products of regularized products [PDF]
Mathematical Research Letters, 2008 The product $\big(\p a_m\big)\cdot\big(\p b_m\big)$ of two regularized products is not in general equal to the regularized product $\p (a_m\cdot b_m)$. We consider the discrepancy $F$, defined by $$ \exp(F ):=\frac{\p (a_m\cdot b_m)}{\big(\p a_m\big)\cdot\big(\p b_m\big)}. $$ When the terms $a_m$ and $b_m$ depend on parameters, we show in certain cases

Affine connections on singular multiply warped products and singular twisted products [PDF]
arXiv, 2022 In this paper, we generalize the results in [Y. Wang: Affine connections on singular warped products. Int. J. Geom. Methods Mod. Phys. 18(5), 2150076, (2021).] to singular multiply warped products and singular twisted products. We study singular multiply warped products and singular twisted products and their curvature with the semi-symmetric metric ...

Natural products as sources of new drugs over the last 25 years.
Journal of Natural Products, 2007 This review is an updated and expanded version of two prior reviews that were published in this journal in 1997 and 2003. In the case of all approved agents the time frame has been extended to include the 251/2 years from 01/1981 to 06/2006 for all ...

Skew-products of higher-rank graphs and crossed products by semigroups [PDF]
, 2013 We consider a free action of an Ore semigroup on a higher-rank graph, and the induced action by endomorphisms of the $C^*$-algebra of the graph. We show that the crossed product by this action is stably isomorphic to the $C^*$-algebra of a quotient graph.

A Study of Product Production in Software Product lines [PDF]
, 2004 A software product line organization exists to produce products. Much of the research on creating products via product lines has focused on developing core assets such as requirements, architectures, and components. This technical note presents the results of a study that focused on how product line organizations create products (e.g., their production
