Investigating potential planetary nebula/cluster pairs

Pairs of Bubbles in Planetary Nebulae and Clusters of Galaxies

I point to an interesting similarity in the morphology and some nondimensional quantities between pairs of X-ray-deficient bubbles in clusters of galaxies and pairs of optical-deficient bubbles in planetary nebulae (PNs). This similarity leads me to postulate a similar formation mechanism. This postulate is used to strengthen models for PN shaping by jets (or collimated fast winds: CFW). The pr...

An Epigenetic Pilot Study Investigating Biomarkers in Maternal-Infant Pairs

Axisymmetric and triaxial MOND density-potential pairs

We present a simple method, based on the deformation of spherically symmetric potentials, to construct explicit axisymmetric and triaxial MOND densitypotential pairs. General guidelines to the choice of suitable deformations, so that the resulting density distribution is nowhere negative, are presented. This flexible method offers for the first time the possibility to study the MOND gravitation...

Investigating the Aesthetic Potential of Computational Composites

A computational composite is a material in which computations contribute to the properties of the material through their capability to control transitions between states in the other components of the composite. By letting the computer out of the box and into composite materials, we gain a new class of design materials, which hold aesthetic expressions we have not yet encountered. But, this cla...

Investigating Potential Mechanisms of Obesity by Metabolomics

Obesity is a serious health problem with an increased risk of several common diseases including diabetes, cardiovascular disease, and cancer. Metabolomics is an emerging analytical technique for systemic determination of metabolite profiles, which is useful for understanding the biochemical changes in obesity or related diseases both in individual organs and at the organism level. Increasingly,...
