“Dulling the Edges”

The Maximum Number of Edges in a Strongly Multiplicative Graph

The Extrema Edges

We present a new approach to model edges in monochrome images. The method is divided in two parts: the localization of possible edge points and their valuation. The first part is based on the theory of minimal paths, where the selection of an energy and a set of sources determines a partition of the domain. Then, the valuation is obtained by the creation of a contrast driven hierarchy of partit...

A new role for microbiota? Dulling the thrust of serotonin and 5-HT3 signaling cascade.

THE IMPORTANCE OF SEROTONIN in gastrointestinal biology is often overlooked given the intense interest of investigators focused on neurotransmitter (mal)functions of the central nervous system. Regardless, the gastrointestinal tract is the major site of serotonin (5-hydroxytryptamine, 5-HT) production (95%) and its crucial role as a paracrine mediator and neurotransmitter in regulating gastroin...

The EDGES of the Mantle

The core-mantle boundary region is often considered to be the source of narrow upwellings which drive or influence plate motions and continental breakup, fuel large igneous provinces and generate volcanic chains. The plume hypothesis has influenced most fields of geochemistry, petrology, geodynamics and mantle evolution. The key axioms underlying the plume paradigm are identified: Axioms are se...

The edges of home ownership

This bulletin is based on research by Professor Gavin Wood and Dr Melek Cigdem at the AHURI Research Centre—RMIT University, Associate Professor Rachel Ong at the AHURI Research Centre—Curtin University and Professor Susan J. Smith at Cambridge University. The research sought to understand the pattern and circumstances in which households in mainstream home ownership churn in and out of home ow...
