Background: This study investigated many cancer medicines using a wide range of degree sum-based topological indices and entropy. These numerical numbers, commonly referred to as topological indices or molecular descriptors, depict a substance's molecular structure. They have been successfully used to properly reflect different physicochemical properties in a number of Quantitative Structure-Property Relationship (QSPR) and Quanti-tative Structure-Activity Relationship (QSAR) research studies.
Objective: The purpose of the study was to investigate the relationships between topological neighborhood indices and physicochemical properties using the QSPR model and linear re-gression methodology.
Methods: We employed linear regression methodology within the QSPR model to examine the connections between physicochemical characteristics and topological neighborhood in-dices.
Results: The results revealed a significant correlation between the neighborhood indices un-der scrutiny and the physicochemical features of the potential drugs under investigation.
Conclusion: As a result, both neighborhood topological indices and entropy demonstrate potential as valuable tools for future QSPR investigations when evaluating anticancer medi-cations.

The bioactive organosulfur compound diallyl sulfide (DAS), found in garlic and onions, was analyzed using density functional theory (DFT). DAS exhibits antimicrobial and anticancer properties, making it a potential candidate for drug discovery. Geometry optimization revealed bond lengths and angles consistent with electron delocalization.

In whitlockite-type compounds, the Eu ion can emit in a wide region from blue to yellow, but its luminescent mechanism remains unclear. Here, we performed a topological crystallography analysis of the whitlockite structure and first clarified the origin of the blue narrow emission band. Specifically, close-packing theory was used to reveal the topological character of β-Ca(PO) and describe its evolution from (PO) ( = Ba, Sr).

Narrow-linewidth lasers are essential for coherent optical applications, including communications, metrology, and sensing. Although compact semiconductor lasers with narrow linewidths have been demonstrated, achieving high spectral purity generally necessitates passive external cavities based on photonic integrated circuits. This study presents a theoretical and experimental demonstration of a monolithic optical injection locking topological interface state extended (MOIL-TISE) laser.

Obstructive sleep apnea (OSA), one of the most common sleep disorders globally, is closely linked to brain function. Resting-state electroencephalography (EEG), due to its convenience, cost-effectiveness, and high temporal resolution, serves as a valuable tool for exploring the human brain function. This study utilized a large cohort with 968 participants who joined in 15-minute daytime resting-state EEG acquisition and overnight polysomnography (PSG) monitoring.

Poly(3-hexylthiophene) (P3HT)-based complex topological copolymers have attracted a great deal of attention for their unique electrical and optical properties. In this contribution, the P3HT-based Janus fibers with controlled lengths were innovatively prepared by sequential crystallization-driven self-assembly (CDSA) of poly(--butylstyrene)--polyisoprene--poly(3-hexylthiophene) (PBS--PI--P3HT) triblock copolymer, cross-linking of the interlayer PI region, and dissociation of fibers in good solvent. The comprehensive characterizations showed that the PBS/P3HT Janus fibers have nearly half the width of PBS--PI--P3HT fibers and fiber lengths close to or slightly shorter than those of PBS--PI--P3HT fibers, indicating that the Janus fibers with adjustable lengths could be prepared in a large window range.
