Imaging and Genetic Biomarkers Predicting Transition to Psychosis

2018
The search for diagnostic and prognostic biomarkers in schizophrenia care and treatment is the focus of many within the research community. Longitudinal cohorts of patients presenting at elevated genetic and clinical risk have provided a wealth of data that has informed our understanding of the development of schizophrenia and related psychotic ...

Phase Transitions in Genetic Programming Search

2007
Phase transitions occur in computational, as well as thermodynamic systems. Of particular interest is the possibility that phase transitions occur as a consequence of GP search. If this were so, it would allow for a statistical mechanics approach and quantitative comparisons of GP with a broad variety of rigorously described systems.

Evolutionary transition on Virus-Evolutionary Genetic Algorithm

Proceedings of 1997 IEEE International Conference on Evolutionary Computation (ICEC '97), 2002
The paper deals with a genetic algorithm (GA) based on the virus theory of evolution (VEGA) and evolutionary transition of a population. VEGA can self adaptively change the searching ratio between local search and global search according to the current state of population of candidate solutions.

“Biomarking” the transition from genetic risk to kidney disease

Kidney International, 2018
Only some individuals carrying the high-risk APOL1 genotype go on to develop kidney disease phenotypes. In this issue of Kidney International, Nadkarni and colleagues report the associations of several biomarkers with renal outcomes in individuals with high-risk APOL1 genotypes.

Genetic and Environmental Influences on Transitions in Drug Use

Behavior Genetics, 1999
Genetic and environmental factors influence drug abuse, but abuse represents the culmination of a sequence of events. Different levels of use may have different determinants and these determinants may differ across drug types. Approximately 3200 male-male twin pairs from the Vietnam Era Twin Registry were interviewed by telephone.

Speciation: The Genetic Transition

2000
Abstract The genetic changes leading to the formation of new species are poorly under stood and are the subject of considerable debate. Some evolutionists propose that major gene changes may propel populations into different reproductive or ecological realms and thereby promote speciation (Gottlieb, 1984).

Healthcare Coordination and Transition for Individuals with Genetic Conditions

Maternal and Child Health Journal, 2015
This study aimed to examine insurance coverage, use of the healthcare system, satisfaction with care, transition from pediatric to adult healthcare services, and social and emotional support for individuals with genetic conditions. In June 2013, the National Genetics Education and Consumer Network surveyed US individuals with genetic conditions about ...

Adjusting Real-Time Mode Transitions via Genetic Algorithms

2017 16th IEEE International Conference on Machine Learning and Applications (ICMLA), 2017
The problem of mode transition schedulability of real-time systems is examined using a genetic algorithm. Due to the mode transition, there can be an overuse of the resource, i.e. the processor(s). A mode transition deadline is a time period in which the outgoing mode(s) have to finish, and then after the mode transition the resource can be completely ...

Transit network design by genetic algorithm with elitism

Transportation Research Part C: Emerging Technologies, 2014
Abstract The transit network design problem is concerned with the finding of a set of routes with corresponding schedules for a public transport system. This problem belongs to the class of NP-Hard problem because of the vast search space and multiple constraints whose optimal solution is really difficult to find out.
