EFFECTIVE INTERACTIONS ARE EFFECTIVE INTERACTIONS [PDF]
The subject of effective interactions is introduced and applications in both quantum mechanics and quantum field theory are presented. In particular the use of chiral perturbation theory as an effective low energy description of QCD is developed and it is argued that such methods rally are effective in both the meson and baryonic sectors.

Triparental plants provide direct evidence for polyspermy induced polyploidy
The fertilization of an egg by more than one sperm is typically lethal. Here, via a novel reporter assay, Nakel et al. report the generation of triparental triploid Arabidopsis plants, implying that polyspermy is a plausible route toward polyploidy ...

Interaction Grammar (IG) is a grammatical formalism based on the notion of polarity. Polarities express the resource sensitivity of natural languages by modelling the distinction between saturated and unsaturated syntactic structures. Syntactic composition is represented as a chemical reaction guided by the saturation of polarities.

The Machinery of Interaction [PDF]
This paper revisits the Interaction Abstract Machine (IAM), a machine based on Girard’s Geometry of Interaction, introduced by Mackie and Danos & Regnier. It is an unusual machine, not relying on environments, presented on linear logic proof nets, and whose soundness proof is convoluted and passes through various other formalisms. Here we provide a new

The pectin methylesterase action is usually studied in a homogeneous aqueous medium in the presence of a large excess of soluble substrate and water. However in the cell wall, the water content is much lower, the substrate is cross-linked with itself or ...

Neutrinos and their interactions [PDF]
We present a short overview of the importance of the study of "Neutrino Interactions in the Intermediate and High Energy Region", with an introduction to the neutrinos and a very brief description about the collection of invited articles.

Multiple Interactions in Herwig++ [PDF]
In this contribution we describe a new model of multiple partonic interactions that has been implemented in Herwig++. Tuning its two free parameters we find a good description of CDF underlying event data.

Rapid evolution of bacterial mutualism in the plant rhizosphere
Beneficial plant-microbe interactions are common in nature, but direct evidence for the evolution of mutualism is scarce. Here, Li et al. experimentally evolve a rhizospheric bacterium and find that it can evolve into a mutualist on a relatively short ...
