Spatially structured genetic variation in a broadcast spawning bivalve: quantitative vs. molecular traits [PDF]

, 2003
Understanding the origin, maintenance and significance of phenotypic variation is one of the central issues in evolutionary biology. An ongoing discussion focuses on the relative roles of isolation and selection as being at the heart of genetically based

Socioeconomic status and health behavior in children and adolescents: a systematic literature review

Frontiers in Public Health, 2023
Socioeconomic status affects individuals’ health behaviors and contributes to a complex relationship between health and development. Due to this complexity, the relationship between SES and health behaviors is not yet fully understood.

Prenatal developmental origins of behavior and mental health: The influence of maternal stress in pregnancy.

Neuroscience and Biobehavioral Reviews, 2017
Accumulating research shows that prenatal exposure to maternal stress increases the risk for behavioral and mental health problems later in life. This review systematically analyzes the available human studies to identify harmful stressors, vulnerable ...

Estimating $$\chi _\mathrm {top}$$ χtop lattice artifacts from flowed SU(2) calorons

European Physical Journal C: Particles and Fields, 2019
Lattice computations of the high-temperature topological susceptibility of QCD receive lattice-spacing corrections and suffer from systematics arising from the type and depth of gradient flow.

Structural Characteristics of Reaction Tissue in Plants

Plants, 2023
To maintain or adjust posture under the challenges of gravity and increased self-weight, or the effects of light, snow, and slope, plants have the ability to develop a special type of tissue called reaction tissue.

Systematic behavior of electro-optic chromophore photostability [PDF]

Optics Letters, 2000
The wavelength dependence of the one-photon absorption-induced photodegradation rate has been measured from the visible to the near IR for a variety of electro-optic chromophore-doped polymers. Systematic behavior is identified. The lifetime of the electro-optic activity is found to increase exponentially over 4-6 orders of magnitude for wavelengths ...
