Linear response at criticality

Description: In this article, the authors study a set of cooperatively interacting units at criticality, and prove with analytical and numerical arguments that they generate the same renewal non-Poisson intermittency as that produced by blinking quantum dots.

Loitering at the hilltop on exterior domains

Description: In this article, the author proves the existence of an infinite number of radial solutions of Δu+f(u)=0 on the exterior of the ball of radius R>0 centered at the origin and f is odd with f<0 on (0,ÎČ), f>0 on (ÎČ,ÎŽ), and f≡0 for u>ÎŽ. The primitive F(u)=∫u0f(t)dt has a "hilltop" at u=ÎŽ which allows one to use the shooting method and ODE techniques to prove the existence of solutions.

Long-distance communication and signal amplication in systemic acquired resistance

Description: This review article summarizes the involvement and interaction between long-distance systemic acquired resistance (SAR) signals and details the recently discovered role of lysine catabolite pipecolic acid (Pip) in defense amplification and priming that allows plants to acquire immunity at the systemic level.

Lophozonia tree cavities used for nesting by Slender-billed Parakeets (Enicognathus leptorhynchus) in the central valley of southern Chile: a potentially vanishing keystone resource

Description: This article describes and quantifies characteristics of southern beech (Lophoonia obliqua) trees and their associated cavities used for nesting by Slender-billed Parakeets in the central valley of southern Chile.

Loss of function of folylpolyglutamate synthetase 1 reduces lignin content and improves cell wall digestibility in Arabidopsis

Description: This article observes genetic and biochemical support for the importance of folylpolyglutamates in the lignocellulosic pathway and reinforces previous observations that targeting a single FPGS isoform for down-regulation leads to reduced lignin in plants.

Magnetobound positronium and protonium

Description: This article investigates the formation of magnetobound positronium and protonium via classical trajectory simulations of binary point charge interactions in an external magnetic field. The results of computer simulations of the fully three-dimensional trajectories of classical and non-relativistic point charges with the same mass, equal charge magnitude, and opposite sign are reported. The simulations show the formation of magnetobound positronium and protonium. The results yield formation cro
