DOI: 10.1002/hbm.24888
Abstract: Dispositional optimism reflects one's generalized positive expectancies for future outcomes and plays a crucial role in personal developmental outcomes and health (e.g., counteracting related mental disorders such as depression and anxiety). Increasing evidence has suggested… read more here.

DOI: 10.1088/1475-7516/2025/08/089
Abstract: We investigate linear matter density perturbations in the ΛsCDM scenario, in which the Λ is replaced by one that undergoes a late-time (z ∼ 2) mirror AdS-dS transition, resulting in distinct growth dynamics that shape… read more here.

DOI: 10.1142/s0219887825400067
Abstract: By employing summary statistics obtained from Persistent Homology (PH), we investigate the influence of Redshift Space Distortions (RSD) on the topology of excursion sets formed through the super-level filtration method applied to three-dimensional matter density… read more here.

DOI: 10.3390/brainsci11091158
Abstract: Visceral adipose tissue accumulation is an important determinant of metabolic risk and can be estimated by the visceral adiposity index (VAI). Visceral adiposity may impact brain regions involved in eating behavior. We aimed to examine… read more here.
