PHENOLOGICAL RELATIONSHIPS OF MODEL AND MIMIC SALAMANDERS [PDF]

open access: yesEvolution, 1981
Models and mimics may be temporally isolated as long as both model and mimic are contacted by a single predator that learns to avoid the model and subsequently contacts and avoids the mimic. Bobisud (1978) developed a mathematical model to explain the advantage to the mimic in delaying its activity, and Huheey (1980) extended the same idea to explain ...

A Bilateral Comparison of Fruit and Vegetable Consumption: United States and Canada

open access: yesJournal of Agricultural and Resource Economics, 2005
Many public programs promote diets rich in fruits and vegetables based on evidence of the derived health benefits. Still, produce consumption in the United States lags behind other nations, even its most culturally similar neighbor--Canada.

A Four-Dimensional Organoid System to Visualize Cancer Cell Vascular Invasion

open access: yesBiology, 2020
Vascular invasion of cancer is a critical step in cancer progression, but no drug has been developed to inhibit vascular invasion. To achieve the eradication of cancer metastasis, elucidation of the mechanism for vascular invasion and the development of ...

Models and tissue mimics for brain shift simulations [PDF]

open access: yesBiomechanics and Modeling in Mechanobiology, 2017
Capturing the deformation of human brain during neurosurgical operations is an extremely important task to improve the accuracy or surgical procedure and minimize permanent damage in patients. This study focuses on the development of an accurate numerical model for the prediction of brain shift during surgical procedures and employs a tissue mimic ...

MIMIC modelling with instrumental variables: A 2SLS-MIMIC approach

open access: yes, 2020
Multiple Indicators Multiple Causes (MIMIC) models are type of structural equation models, a theory-based approach to confirm the influence of a set of exogenous causal variables on the latent variable, and also the effect of the latent variable on observed indicator variables.

Animal Model That Mimics Atherosclerotic Plaque Rupture [PDF]

open access: yesCirculation Research, 1998
Abstract —Atherosclerotic plaque rupture is the main cause of coronary thrombosis and myocardial infarcts. Currently, there is no animal model of plaque disruption. We have developed a rabbit model in which an atherosclerotic plaque can be ruptured at will after an inflatable balloon becomes embedded into the plaque ...

Model aversiveness and the evolution of imperfect Batesian mimics

open access: yesBehavioral Ecology, 2023
AbstractThere are numerous examples of Batesian mimics that only imperfectly resemble their models. Given that inaccurate mimics are known to be predated more frequently than accurate ones, imperfect mimicry therefore poses something of a conundrum. One putative explanation, the relaxed selection hypothesis, predicts that when the cost of attacking a ...
