Photonic density of states of two-dimensional quasicrystalline photonic structures
A large photonic band gap (PBG) is highly favorable for photonic crystal devices. One of the most important goals of PBG materials research is identifying structural design strategies for maximizing the gap size. We provide ...
Reversible Shape and Plasmon Tuning in Hollow AgAu Nanorods
The internal structure of hollow AgAu nanorods created by partial galvanic replacement was manipulated reversibly, and its effect on optical properties was mapped with nanometer resolution. Using the electron beam in a ...
Oral cancer point of care diagnostics
A point of care diagnostic test, device and disposables for determining a patient risk for oral cancer in the same visit that a sample is collected.
There Is Time for Calculation in Speed Chess, and Calculation Accuracy Increases With Expertise
The recognition–action theory of chess skill holds that expertise in chess is due primarily to the ability to recognize familiar patterns of pieces. despite its widespread acclaim, empirical evidence for this theory is ...
Emerging U.S. Policy Toward Russia
Russia’s invasion of Georgia in August 2008 brought the subject of U.S.-Russian relations to the forefront of political discourse, albeit for a short while. Since then, the United States’ main foreign policy concerns have ...
Exploring phylogenetic hypotheses via Gibbs sampling on evolutionary networks
Abstract Background Phylogenetic networks are leaf-labeled graphs used to model and display complex evolutionary relationships that do not fit a single tree. There are two ...
