A SnOx thin film with a thickness of 400 ± 20 nm was deposited on a glass substrate and thermally oxidized at temperatures ranging from 573 K to 673 K. The structural surface morphology of SnOx thin films is checked. X-ray diffraction analysis indicated that films oxidized at 573K and 623K contain SnO, Sn3O4, and SnO2, as well as residual metallic tin. When the oxidation temperature was increased to 673K, the SnO₂ peaks became more prominent while the metallic Sn peak weakened. AFM studies indicated that the roughness of the films changed with different oxidation temperatures, which means that the oxidation temperature has a direct effect on the surface nature of the SnOx films. On the other hand, films oxidized at 673K (SnO2) are use

In this paper, we study and introduce two new concepts in module theory: semi-coessential submodules and semi-coclosed submodules. These notions are generalizations of the classical concepts of coessential and coclosed submodules and aim to provide a broader framework for analyzing module structures. We investigate the main properties of these submodules and examine their relationships with coessential and coclosed submodules. Several characteristics associated with these ideas are explored, including conditions under which a submodule can be considered semi-coessential or semi-coclosed. The definitions are formulated in terms of factor modules and the semi-small condition, allowing a sy

Classical numerical integration methods, such as Simpson’s rule and Gaussian quadrature, perform well for smooth functions but lose accuracy near discontinuities. This paper introduces a Selective Error-Correcting Adaptive Quadrature algorithm (SECAQ), a method designed to address this issue. SECAQ identifies intervals with large local error or sharp changes, estimates jump sizes using one-sided evaluations, and applies compact correction terms activated only near the discontinuity. These localized corrections restore smoothness within each subinterval and can enable the base quadrature rule to achieve its full theoretical accuracy. Numerical tests involving jumps, cusps, and oscillatory functions demonstrate that SECAQ restores fourth
