A rigorous evaluation of crossover and mutation in genetic programming [PDF]

, 2009
The role of crossover and mutation in Genetic Programming (GP) has been the subject of much debate since the emergence of the field. In this paper, we contribute new empirical evidence to this argument using a rigorous and principled experimental method ...

Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

Advanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

A case-crossover study of air pollution exposure during pregnancy and the risk of stillbirth in Tehran, Iran

Scientific Reports
The growing fetus is very sensitive to environmental conditions. There is limited and conflicting evidence about the short-term effects of exposure to air pollutants on the pregnancy outcome.

A case of crossover mixed analyses in mathematics education research

Methods in Psychology
Crossover mixed analysis, which integrates qualitative and quantitative traditions, is fruitful for advancing mixed methods research. Employing a pragmatic theoretical perspective, we report a case study investigating the use of crossover mixed analyses ...

Introduction to case-crossover study design for drug-drug interaction. [PDF]

Ann Clin Epidemiol
This article introduces the basic concept of a novel 6-parameter model case-crossover study with active comparator design. While case-crossover study design eliminates time-invariant confounding, the 6-parameter model as a modified version also allows studying the effect of drug initiation patterns between two interacting drugs.

Antipsychotic medications and stroke in schizophrenia: A case-crossover study

PLOS ONE, 2017
The association between antipsychotic use and the risk of stroke in schizophrenic patients is controversial. We sought to study the association in a nationwide cohort with schizophrenia.Using a retrospective cohort of patients with schizophrenia (N = 31,976) derived from the Taiwan National Health Insurance Research Database, 802 new-onset cases of ...

A case-crossover study of laceration injuries in pork processing

Occupational and Environmental Medicine, 2012
The authors estimated the associations between transient risk factors and laceration injuries in workers at two meatpacking plants in the Midwest.The case-crossover design was used to collect within-subject transient work task and personal-level exposure information.

Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5

Advanced Functional Materials, EarlyView.
We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...

Guanosine‐Quadruplex Hydrogels as Dynamic, Mechanically Tunable and Ion Conductive 3D Scaffolds for Cell Culture Applications

Advanced Functional Materials, EarlyView.
Versatile guanosine‐quadruplex (GQ) hydrogels are developed as dynamic biomatrices for cell culture. These scaffolds are fabricated under mild aqueous conditions, present improved stability, tunable mechanical properties within physiological ranges; fibrillar, porous microstructure, ion conductivity, and cytocompatibility.
