Correlation networks derived from multivariate data appear in many applications across the sciences. These are usually dense and require sparsification to detect meaningful structure. However, current methods for sparsifying correlation struggle with balancing overfitting underfitting. We propose a module-based cross-validation procedure threshold these networks, making modular structure an int...
In medicinal chemistry, the link between structure and activity is essential. We are seeking to relate chemical reactivity properties, which has gained popularity recently. this study, scaffolds from three antioxidants were changed new derivatives show that their biological effects as would change. also reviewed anticancer of these medications (based on SRB test) find other may be related struc...
ZnO and Cu doped[1] (CZO) thin films were prepared by radio frequency sputtering. The structural and optical properties of thin films were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), optical spectrophotometer, and photoluminescence (PL) techniques. ZnO thin films showed crystalline and micro-stress defects in the crystal lattice. Annealing of CZO thin films increa...
it is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. quantitative structure – activity relationship (qsar) studies and quantitative structure –property relationship (qspr) studies are active areas of chemical research that focus on the nature ofthis dependency. topological indices are the numerical value associated with chemical constitution...
Introduction: Studies have shown that bank clerks experience high levels of stress. Stress is known as the main cause of reduction of job satisfaction and staff commitment and overall organization performance. This study aimed to investigate the association between psychosocial stressors, organizational structure, and job satisfaction. Methods and Materials: This cross-sectional study was...
