We show that the Hamiltonian of a multiband spin-orbit coupled semiconductor nanowire with Zeeman splitting and s-wave superconductivity is approximately chiral symmetric. The chiral symmetry becomes exact when only one pair of confinement bands is occupied and the Zeeman splitting is parallel to the nanowire. In this idealized case the Hamiltonian is in the BDI symmetry class of the topological classification of band Hamiltonians, allowing an arbitrary integer number of zero-energy Majorana fermion modes at each end. In the realistic case of multiband wires (Zeeman splitting still parallel to the length) the chiral symmetry is approximate and results in multiple near-zero-energy end states with increasing Zeeman splitting. The existence of such low energy end states implies the vanishing of the minigap with increased Zeeman splitting which can only be restored by breaking the approximate chiral symmetry by a second Zeeman field. © 2012 American Physical Society.

Gene flow estimation is essential for characterizing local adaptation, speciation potential and connectivity among threatened populations. New model-based population genetic methods can resolve complex demographic histories, but many studies in fields such as landscape genetics continue to rely on simple rules of thumb focused on gene flow to explain patterns of spatial differentiation. Here, we show how methods that use gene genealogies can reveal cryptic demographic histories and provide better estimates of gene flow with other parameters that contribute to genetic variation across landscapes and seascapes. We advocate for the expanded use and development of methods that consider spatial differentiation as the product of multiple forces interacting over time, and caution against a routine reliance on post-hoc gene flow interpretations. © 2011 Elsevier Ltd.

The unique and striking material properties of chalcogenide glasses have been studied for decades, providing applications in the electronics industry, imaging and more recently in photonics. This Review summarizes progress in photonic devices that exploit the unique optical properties of chalcogenide glasses for a range of important applications, focusing on recent examples in mid-infrared sensing, integrated optics and ultrahigh-bandwidth signal processing. © 2011 Macmillan Publishers Limited.

Endonuclease V (endo V) was first discovered as the fifth endonuclease in Escherichia coli in 1977 and later rediscovered as a deoxyinosine 3′ endonuclease. Decades of biochemical and genetic investigations have accumulated rich information on its role as a DNA repair enzyme for the removal of deaminated bases. Structural and biochemical analyses have offered invaluable insights on its recognition capacity, catalytic mechanism, and multitude of enzymatic activities. The roles of endo V in genome maintenance have been validated in both prokaryotic and eukaryotic organisms. The ubiquitous nature of endo V in the three domains of life: Bacteria, Archaea, and Eukaryotes, indicates its existence in the early evolutionary stage of cellular life. The application of endo V in mutation detection and DNA manipulation underscores its value beyond cellular DNA repair. This review is intended to provide a comprehensive account of the historic aspects, biochemical, structural biological, genetic and biotechnological studies of this unusual DNA repair enzyme. © 2012 Springer Basel.

Annual Review of Materials Research | Year: 2011

Over the past 1015 years, there have been significant advances in the scientific understanding as well as in the performance of thermoelectric (TE) materials. TE materials can be incorporated into power generation devices that are designed to convert waste heat into useful electrical energy. These TE materials can also be used in solid-state refrigeration devices for cooling applications. The conversion of waste heat into electrical energy will certainly play a role in our current challenge for alternative energy technologies to reduce our dependence on fossil fuels and to reduce greenhouse gas emissions. This article provides an overview of the various TE phenomena and discusses some of the primary TE materials that are currently being investigated. Several of the key parameters and terminology are defined and discussed along with an overview of some of the current and emerging technologies. The phonon glasselectron crystal approach to new TE materials for developing new materials is presented along with the role of solid-state crystal chemistry and the criteria for higher-performance TE materials. This article discusses TE phenomena, the selection criteria for higher-performance materials, and a few key materials. © 2011 by Annual Reviews. All rights reserved.
