DOI: 10.1007/jhep07(2025)124
Abstract: It is notoriously difficult to construct a stable non-singular bouncing cosmology that avoids all possible instabilities throughout the entire evolution of the universe. In this work, we explore whether a non-singular bounce driven by a… read more here.

DOI: 10.1016/j.prro.2016.06.010
Abstract: PURPOSE We hypothesized that high-dose stereotactic body radiation therapy (SBRT) would lead to faster time to nadir and lower nadir values compared with conventional radiation therapy experiences. We now report prostate-specific antigen (PSA) kinetics following… read more here.

DOI: 10.1021/acs.est.4c04312
Abstract: Viscosity, or the “thickness,” of aerosols plays a key role in atmospheric processes like ice formation, water absorption, and heterogeneous kinetics. However, the viscosity of sea spray aerosols (SSA) has not been widely studied. This… read more here.
