In this work we compute the Chen–Ruan cohomology of M1,n and M1,n, and its algebraic counterpart: the stringy Chow ring. We suggest a definition for a Chen–Ruan tautological ring in genus 1, which is both a subring of the Chen–Ruan cohomology and of the stringy Chow ring.

Background: Nanoparticles (NPs) are colloidal systems with particles ranging from 10 to 100 nm in diameter. Because of their large surface-volume ratio, NPs are biologically active materials that could interact with biomolecules and microorganisms, enter into the cells, and affect the metabolic functions. The study aimed to biosynthesize silver nanoparticles (Ag-NPs) from Capparis spinosa fruit...

in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...

In this manuscript, a new class of extended (m1,m2)-convex and concave functions is introduced. After some properties of (m1,m2)-convex functions have been given, the inequalities obtained with Hölder and Hölder-İşcan and power-mean and improwed power-mean integral inequalities have been compared and it has been shown that the inequality with Hölder-İşcan inequality gives a better approach than...

Palladium doped silica membranes were synthesized by the sol-gel method using two different procedures. The first palladium-doped silica membrane (M1) was synthesized with a coating of four layers of silica-palladium sol. The second membrane (M2) was synthesized with a coating of two silica layers followed by a coating of two silica-palladium layers. Scanning electron microscopy (SEM) proved th...

Background: Macrophage polarization plays a critical role in determining the inflammatory states. Hepcidin is a key negative regulator of iron homeostasis and functions. Although hepcidin has been shown to affect ferroportin expression in macrophages, whether it affects macrophage polarization is still largely unknown. Objective: To address whether hepcidin ind...

Merkel cell polyomavirus (MCPyV) is considered the etiological agent of Merkel cell carcinoma and persists asymptomatically in the majority of its healthy hosts. Largely due to the lack of appropriate model systems, the mechanisms of viral replication and MCPyV persistence remain poorly understood. Using a semi-permissive replication system, we here report a comprehensive analysis of the role o...

Let $R$ be a commutative ring and $mathbb{A}(R)$ be the set of all ideals with non-zero annihilators. Assume that $mathbb{A}^*(R)=mathbb{A}(R)diagdown {0}$ and $mathbb{F}(R)$ denote the set of all finitely generated ideals of $R$. In this paper, we introduce and investigate the {it finitely generated subgraph} of the annihilating-ideal graph of $R$, denoted by $mathbb{AG}_F(R)$. It is the (undi...
