Abstract

We consider a class of branching processes with countably many types which we refer to as Lower Hessenberg branching processes. These are multitype Galton-Watson processes with typeset X = {0, 1, 2,...}, in which individuals of type i may give birth to offspring of type j

Childbirth

Childbirth, also known as labour, parturition and delivery, is the completion of pregnancy where one or more babies exits the internal environment of the mother via vaginal delivery or caesarean section. In 2019, there were about 140.11 million human births globally. In the developed countries, most deliveries occur in hospitals, while in the developing countries most are home births. The most common childbirth method worldwide is vaginal delivery.

Water birth

Water birth is labor and sometimes delivery that occurs in water, usually a birthing pool. The American College of Obstetricians and Gynecologists does not recommend birthing in water as the safety has not been determined. Proponents believe childbirth in water results in a more relaxed, less painful experience that promotes a midwife-led model of care. Critics argue that the safety of waterbirth has not been scientifically proven and that a wide range of adverse neonatal outcomes have been documented, including increased mother or child infections and the possibility of infant drowning.

Birth

Birth is the act or process of bearing or bringing forth offspring, also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a developmental stage when it is ready to feed and breathe. In some species the offspring is precocial and can move around almost immediately after birth but in others it is altricial and completely dependent on parenting.
