TL;DR: In this article, the authors consider off-diagonal contributions to double sums over periodic orbits that arise in semiclassical approximations for spectral statistics of classically chaotic quantum systems and identify pairs of periodic orbits whose actions are strongly correlated.

TL;DR: A summary of the current understanding of molecular electronics combined with selected state-of-the-art results at a level accessible to the advanced undergraduate or novice postgraduate can be found in this paper.

TL;DR: A review of the evolution of the understanding of correlated two-electron dynamics and its importance for doubly excited resonance states is presented in this article, with an emphasis on the concepts introduced.

TL;DR: Systematic analysis of protein interactions of 3-aa loop extension (TALE) homeodomain proteins, fundamental regulators of plant meristem function and leaf development, revealed a highly connected, complex network that includes nine members of Arabidopsis thaliana ovate family proteins (AtOFPs), a plant-specific protein family, indicating a close functional connection to TALE homeodome proteins.

TL;DR: It is found that nanoribbons with atomically straight, symmetric edges show zero spin conductance but nonzero spin Hall conductance, and only nanoriberbons with asymmetrically shaped edges give rise to a finite spin Conductance and can be used for spin injection into graphene.
