Periventricular leukomalacia (PVL) is a form of white-matter brain injury, characterized by the necrosis (more often coagulation) of white matter near the lateral ventricles. [ 1 ] [ 2 ] It can affect newborns and (less commonly) fetuses; premature infants are at the greatest risk of neonatal encephalopathy which may lead to this condition.
In statistics, especially in Bayesian statistics, the kernel of a probability density function (pdf) or probability mass function (pmf) is the form of the pdf or pmf in which any factors that are not functions of any of the variables in the domain are omitted. [1] Note that such factors may well be functions of the parameters of the
1871 and 1872 also saw the emergence of a new approach in textology, namely, publishing the PVL as a separate text rather than as part of another chronicle. [9] Those years, lithographic versions of the Hypatian and Laurentian texts of the PVL were published, although both titles claimed to represent "the" Povest' vremennykh let. [9]
Panton–Valentine leukocidin (PVL) is a cytotoxin—one of the β-pore-forming toxins. The presence of PVL is associated with increased virulence of certain strains (isolates) of Staphylococcus aureus .
The Pacific View League (PVL) was a high school athletic conference in California affiliated with the CIF Southern Section. The league was formed in 1998, [ 1 ] [ 2 ] pulling Camarillo and Channel Islands high schools from the Marmonte League to join Hueneme , Oxnard , and Rio Mesa highs from the Channel League .
Conversely, given i.i.d. normal variables with known mean 1 and unknown variance σ 2, the sample mean ¯ is not an ancillary statistic of the variance, as the sampling distribution of the sample mean is N(1, σ 2 /n), which does depend on σ 2 – this measure of location (specifically, its standard error) depends on dispersion.

The 2024 PVL season was supposed to have two All-Filipino Conferences, the same as the 2023 PVL season, [1] but this plan was later scrapped. [2] This conference was supposed to begin on February 17, 2024, but was later moved to February 20, 2024. [1]
