Crossover Interference, Crossover Maturation, and Human Aneuploidy

open access: yesBioEssays, 2019
A striking feature of human female sexual reproduction is the high level of gametes that exhibit an aberrant number of chromosomes (aneuploidy). A high baseline observed in women of prime reproductive age is followed by a dramatic increase in older women.

The Effect of Distinct Geometric Semantic Crossover Operators in Regression Problems [PDF]

open access: yes, 2015
This paper investigates the impact of geometric semantic crossover operators in a wide range of symbolic regression problems. First, it analyses the impact of using Manhattan and Euclidean distance geometric semantic crossovers in the learning process ...

A simple two-module problem to exemplify building-block assembly under crossover

open access: yes, 2004
Theoretically and empirically it is clear that a genetic algorithm with crossover will outperform a genetic algorithm without crossover in some fitness landscapes, and vice versa in other landscapes.

Optimal and efficient crossover designs for comparing test treatments with a control treatment

open access: yes, 2005
This paper deals exclusively with crossover designs for the purpose of comparing t test treatments with a control treatment when the number of periods is no larger than t+1. Among other results it specifies sufficient conditions for a crossover design to

Nano-electromanipulation of Spin Crossover Nanorods: Towards Switchable Nanoelectronic Devices [PDF]

open access: yes, 2013
The nanoscale manipulation and charge transport properties of the [Fe(Htrz)2(trz)](BF4) spin-crossover compound is demonstrated. Such 1D spin-crossover nanostructures are attractive building blocks for nanoelectronic switching and memory ...

Crossover scaling in two dimensions

open access: yes, 1997
We determine the scaling functions describing the crossover from Ising-like critical behavior to classical critical behavior in two-dimensional systems with a variable interaction range.

Dimensional crossover in quantum critical metallic magnets

open access: yes, 2009
Nearly magnetic metals often have layered lattice structures, consisting of coupled planes. In such a situation, physical properties will display, upon decreasing temperature or energy, a dimensional crossover from two-dimensional (2d) to three ...

Adaptive Linkage Crossover

open access: yesEvolutionary Computation, 1998
Problem-specific knowledge is often implemented in search algorithms using heuristics to determine which search paths are to be explored at any given instant. As in other search methods, utilizing this knowledge will more quickly lead a genetic algorithm (GA) towards better results.

På vei mot barnelitteraturens grense? Erlend Loes Kurtby (2008)

open access: yesBarnboken: Tidskrift för Barnlitteraturforskning, 2012
Toward the limit of children’s literature? Erlend Loe’s Kurtby (2008). Fiction for all ages, books that are intended for children and adult readers alike, became an important subgenre in Norwegian literature for young readers during the 1990s. One of the
