Since all particles in PSO are kept as members of the population throughout the course of the searching process, PSO is the only evolutionary algorithm that does not implement survival of the fittest.
In high income countries where ventilation technology and the use of surfactant have been implemented, the survival of premature babies has improved [ 30].
We implemented a survival advantage to the tumor-propagating cells from clonally related transient cells (Supplementary Methods), although with equal success, we could have implemented the fitness benefit through a reproductive advantage.
The majority of studies implemented different survival analysis techniques, such as log-rank tests or multivariate Cox regression models for the assessment of the PD behaviour of different biomarkers, with the overall survival or progression-free survival being used as end points (Hahn et al, 2008; Kudo et al, 2011).
Survival analysis was implemented using the "survival" R package (Supplementary File 1).
In the first step of 2STEP, data were analysed using survival analysis as implemented in the survival kit V5 [ 30], to produce pseudo-records as defined below.
Updated at 11.25am BST 11.14am BST MacLean: Any layoffs will be limited The next step is for all sides to work together to implement the survival plan for Grangemouth, Calum MacLean says.
"Our focus here today is on trying to implement a survival plan that brings a future for Grangemouth".
Although various radiotherapy techniques and altered fractionation schedules [ 1- 6], as well as different chemotherapeutic regimens [ 7, 8] have been implemented, the overall survival of glioblastoma patients remains rather poor, with a median survival of 12-18 months. 12-18 months
