Kernel density estimation of 100 normally distributed random numbers using different smoothing bandwidths.. In statistics, kernel density estimation (KDE) is the application of kernel smoothing for probability density estimation, i.e., a non-parametric method to estimate the probability density function of a random variable based on kernels as weights.
Placental expulsion. Placental expulsion (also called afterbirth) occurs when the placenta comes out of the birth canal after childbirth. The period of time starting just after the baby is expelled until just after the placenta is expelled is called the third stage of labor. The third stage of labor can be managed actively with several standard ...
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. [ 7 ] In 2019, there were about 140.11 million human births globally. [ 9 ]
Fern test. The fern test is a medical laboratory test used in obstetrics and gynecology. The name refers to the detection of a characteristic " fern like" pattern of vaginal secretions when a specimen is allowed to dry on a glass slide and is viewed under a low-power microscope. The fern test is most commonly used to provide evidence of the ...
Montevideo units are a method of measuring uterine performance during labor. They were created in 1949 by two physicians, Roberto Caldeyro-Barcia and Hermogenes Alvarez, from Montevideo, Uruguay. They are exactly equal to 1 mmHg within 10 minutes. A standard adequate measurement is 200; this is generally equivalent to 27 kPa of combined ...
In embryology, Carnegie stages are a standardized system of 23 stages used to provide a unified developmental chronology of the vertebrate embryo. The stages are delineated through the development of structures, not by size or the number of days of development, and so the chronology can vary between species, and to a certain extent between ...
The myometrium is located between the endometrium (the inner layer of the uterine wall) and the serosa or perimetrium (the outer uterine layer).. The inner one-third of the myometrium (termed the junctional or sub-endometrial layer) appears to be derived from the Müllerian duct, while the outer, more predominant layer of the myometrium appears to originate from non-Müllerian tissue and is ...
[3] [4] The onset of lactation (OL), also referred to as stage II lactogenesis or secretory activation, [1] [4] is one of the three stages of the milk production process. [1] OL is the stage when plentiful production of milk is initiated following the delivery of a full-term infant.
