Recommender systems are chiefly renowned for their applicability in e-commerce sites and social media. For system optimization, this work introduces a method of behaviour pattern mining to analyze the person's mental stability. With the utilization of the sequential pattern mining algorithm, efficient extraction of frequent patterns from the database is achieved.

Methods: This prospective observational study was conducted in the department of Obstetrics and Gynecology, Midnapore Medical College, West Bengal, India.
Topological insulators (TIs) are bulk insulators with metallic surface states that can be described by a single Dirac cone. However, low-dimensional solids such as nanowires (NWs) are a challenge, due to the difficulty of separating surface contributions from bulk carriers. Fabrication of NWs with high surface-to-volume ratio can be realized by different methods such as chemical vapor transport, molecular beam epitaxy, and electrodeposition.

The reaction pathway is governed by the nature of reaction partner. Several dihydrofurocoumarin, furopyranocoumarin, dihydrofuran, dihydrobenzopyran, and dihydrobenzofuran derivatives were obtained as single diastereomers from cyclic or acyclic enol ethers and styrenes.
