Prevalence and Impact of Treatment Crossover in Cardiac Surgery Randomized Trials: A Meta‐Epidemiologic Study

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Crossover dilutes treatment effect and reduces statistical power of intention‐to‐treat analysis. We examined incidence and impact on cardiac surgery randomized controlled trial (RCT) outcomes of crossover from experimental to control ...

TERMA Framework for Biomedical Signal Analysis: An Economic-Inspired Approach

open access: yesBiosensors, 2016
Biomedical signals contain features that represent physiological events, and each of these events has peaks. The analysis of biomedical signals for monitoring or diagnosing diseases requires the detection of these peaks, making event detection a crucial ...

Les dynamiques raciales de la production de Michael Jackson (1979-2001) : aspects commerciaux, musicaux et visuels

open access: yesTransatlantica, 2021
Our article analyses Michael Jackson’s artistic production, through marketing, stylistic and visual aspects, targeting racial dynamics and tensions which invigorate its narrative layers. The first part is about the colorist charts, the ubiquitous posture

Correcting Instruction Expression Logic Errors with GenExp: A Genetic Programming Solution [PDF]

open access: yesComputer Science Journal of Moldova, 2023
Correcting logical errors in a program is not simple even with the availability of an error locating tool. In this article, we introduce GenExp, a genetic programming approach to automate the task of repairing instruction expressions from logical errors.

FPGA Implementation of Crossover Module of Genetic Algorithm

open access: yesInformation, 2019
This paper proposes a hardware realization of the crossover module in the genetic algorithm for the travelling salesman problem (TSP). In order to enhance performance, we employ a combination of pipelining and parallelization with a genetic algorithm (GA)

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

Phase Transitions and Symmetry Breaking in Genetic Algorithms with Crossover [PDF]

open access: yes, 2006
In this paper, we consider the role of the crossover operator in genetic algorithms. Specifically, we study optimisation problems that exhibit many local optima and consider how crossover affects the rate at which the population breaks the symmetry of ...

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.
