Extensions of best approximation and coincidence theorems
International Journal of Mathematics and Mathematical Sciences, 1997 Let X be a Hausdorff compact space, E a topological vector space on which E* separates points, F:X→2E an upper semicontinuous multifunction with compact acyclic values, and g:X→E a continuous function such that g(X) is convex and g−1(y) is acyclic for ...

Connection formulas between Coulomb wave functions
, 2018 The mathematical relations between the regular Coulomb function $F_{\eta\ell}(\rho)$ and the irregular Coulomb functions $H^\pm_{\eta\ell}(\rho)$ and $G_{\eta\ell}(\rho)$ are obtained in the complex plane of the variables $\eta$ and $\rho$ for integer or

Advanced Science, Volume 13, Issue 16, 18 March 2026.A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...

Existence theorems for differential inclusions with nonconvex right hand side
International Journal of Mathematics and Mathematical Sciences, 1986 In this paper we prove some new existence theorems for differential inclusions with a nonconvex right hand side, which is lower semicontinuous or continuous in the state variable, measurable in the time variable and takes values in a finite or infinite ...

Advanced Science, Volume 13, Issue 16, 18 March 2026.Mitochondria‐targeted silver single‐atom carbon dot (T‐AgSA‐CDs) nanozymes enable dual SOD/GPx‐like ROS scavenging, real‐time imaging, and therapeutic effects for acute kidney injury (AKI). Atomically dispersed Ag sites synergize with carbon dots to restore renal redox hemostasis, protect mitochondrial function, mitigate inflammation, facilitate post ...

Food and Energy Security, Volume 15, Issue 2, March/April 2026.ABSTRACT Accurately identifying regional agricultural advantageous industries and optimizing their spatial layout are critical for advancing sustainable peri‐urban land systems. However, existing studies often overlook public preferences and fail to integrate industrial development with agricultural multifunctionality. To address these gaps, this study

neutrosophic pre-continuous multifunctions and almost pre-continuous multifunctions
Neutrosophic Sets and Systems, 2019 In this paper, we introduce neutrosophic upper and neutrosophic lower almost pre-continuous-multifunctions as a generalization of neutrosophic multifunctions. Some characterizations and several properties concerning neutrosophic upper and neutrosophic lower almost pre-continuous- multifunctions are obtained.
