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.

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

CARBON IN SOILS IN FOREST REGIONS OF EUROPEAN-URAL PART OF RUSSIA
Вопросы лесной науки, 2021 The carbon pool of the soil block of the European-Ural part of Russia was estimated on the basis of land categories adopted in the State Forest Register (21 biotopes in total). Published data of 675 soil sections using the coordinates and descriptions of

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 ...

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

Aggregate Productivity and the Productivity of Aggregates [PDF]
International Finance Discussion Papers, 1995 Explanations of procyclical productivity play a key role in a variety of business-cycle models. Most of these models, however, explain this procyclicaIity within a representative-firm paradigm. This procedure is misleading. We decompose aggregate productivity changes into several terms, each of which has an economic interpretation.

Alkane biosynthesis gene expression and its increased production in recombinant cyanobacteria
FEBS Open Bio, EarlyView.The transcription and mRNA structures of the alkane biosynthesis genes ado/aar were analysed in the representative cyanobacteria PCC 6803 and SK1‐2‐1, which produce C17H36 and C15H32, respectively. PCC 6803 transconjugants carrying these genes showed a 1.8‐ to 2.3‐fold increase in C17H36 production.
