OBJECTIVE: To investigate how the interval between membrane rupture and delivery affects the risk of neonatal sepsis and whether duration of labor influences the risk. METHODS: A registry study included 113,568 singleton infants born at term after a trial of labor (elective cesarean deliveries excluded). The incidence of a diagnosis of sepsis during the neonatal period was correlated to the interv
We establish the theory of normal families of meromorphic functions taking values in the extended complex plane, which can be regarded as a metric space equipped with the spherical metric. Using the notion of spherical derivatives, we state and prove Marty's theorem on normal families of meromorphic functions. As a result, we deduce the classical Montel's theorem on relatively compact fami
Evaluating the trade interdependence among countries is the key to understanding critical metal minerals security. By constructing a novel interdependence network, this paper reveals a more comprehensive world hierarchy and risk system of critical metals, and focuses on the interdependencies between China and the US-led MSP countries before and after the Sino-US trade disputes. The results indicat
