Open AccessSecond harmonic Hall responses of insulators as a probe of Berry curvature dipole
Diverse nonlinear optical responses of metallic band states have been characterized in terms of the Berry curvature dipole (BCD) or other multipole structures of Berry curvature. Here, we find that the second ...

Open AccessThe impact of fine particulate matter (PM) on various beneficial functions of human endometrial stem cells through its key regulator SERPINB2
Fine particulate matter (PM) has a small diameter but a large surface area; thus, it may have broad toxic effects that subsequently damage many tissues of the human body. Interestingly, many studies have sugge...

Open AccessNoncanonical functions of glucocorticoids: A novel role for glucocorticoids in performing multiple beneficial functions in endometrial stem cells
Chronic stress has a negative impact on many fertility-related functions; thus, the recent decline in female fertility seems to be at least partially associated with increased stress. The secretion of glucocor...

Rare Benign Inflammatory Tumor of Esophagus Masquerading as Malignancy
Inflammatory myofibroblastic tumors are mesenchymal neoplasms with intermediate biological potential. They tend to affect the lungs and abdominopelvic area but rarely occur in the esophagus. Only a few cases o...

Derivation of equations of motion of an unwinding cable considering transient-state tensile force in time-varying unwinding velocity
Unwinding dynamics refers to the study of nonlinear behaviour, tension profile, entangling, and fracturing in the process of unwinding a fibre from a package through the guide eyelet at a specific unwinding sp...

Open AccessOptical spin-orbit torque in heavy metal-ferromagnet heterostructures
Spin current generation through the spin-orbit interaction in non-magnetic materials lies at the heart of spintronics. When the generated spin current is injected to a ferromagnet, it produces spin-orbit torqu...

Outcomes of Curative-Intent Surgery and Adjuvant Treatment for Pulmonary Large Cell Neuroendocrine Carcinoma
Pulmonary large cell neuroendocrine carcinoma (LCNEC) is pathologically classified as non-small-cell lung cancer (NSCLC), but its clinical behavior is more aggressive than other types of NSCLC. Accordingly, th...

Open AccessQuantum Phase Transition and Entanglement in Topological Quantum Wires
We investigate the quantum phase transition of the Su-Schrieffer-Heeger (SSH) model by inspecting the two-site entanglements in the ground state. It is shown that the topological phase transition of the SSH mo...
