4 Wu, Yong-ShiGround-state degeneracy in the Levin-Wen model for topological phasesWe study the properties of topological phases by calculating the ground-state degeneracy (GSD) of the two-dimensional Levin-Wen (LW) model. Here it is explicitly shown that the GSD depends only on the spatial topology of the system. Then we show that the ground state on a sphere is always nondegener...2012-01-01

7 Sekercioglu, CaganMeasuring the meltdown: drivers of global amphibian extinction and declineHabitat loss, climate change, over-exploitation, disease and other factors have been hypothesised in the global decline of amphibian biodiversity. However, the relative importance of and synergies among different drivers are still poorly understood. We present the largest global analysis of roughly ...2008-01-01
8 Lupton, John MarkMechanisms of spin-dependent dark conductivity in films of a soluble fullerene derivative under bipolar injectionWe report room-temperature pulsed electrically detected magnetic resonance measurements of the dark conductivity of films of the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) under bipolar (electron-hole) and unipolar (electron-rich) injection conditions. Directly after mate...2014-01-01
9 Vardeny, Zeev ValentineMechanically stretchable and reversibly deformable liquid metal-based plasmonicsWe demonstrate that liquid metals are attractive materials for active plasmonic devices at terahertz frequencies. Using a liquid metal injected into an elastomeric mold, we measure the static and stretched transmission properties of aperture arrays.2012-01-01
10 Mishchenko, EugeneEquilibrium currents in chiral systems with nonzero Chern numberWe describe a simple quantum-mechanical approach to calculating equilibrium particle current along the edge of a system with nontrivial band spectrum topology. The approach does not require any a priori knowledge of the band topology and, as a matter of fact, treats topological and nontopological co...2014-01-01
11 Sekercioglu, CaganHabitat use and movements of native forest birds in southern Costa Rican agricultural countrysideWe used radio telemetry to study the habitat use, activity budgets, and movements of three bird species that are found in native forest and coffee plantations of southern Costa Rica. We obtained 7522 locations from Turdus assimilis (n=27), Tangara icterocephala (n=53), and Catharus aurantiirostris (...2003-01-01
12 Sekercioglu, CaganImportance of Ethiopian shade coffee farms for forest bird conservationCoffee is the most important tropical commodity and is grown in high-priority areas for biological conservation. There is abundant literature on the conservation value of coffee farms internationally, but there has been little research on this topic in Africa. Ethiopia is a diverse and little-studie...2014-01-01
13 Gerton, JordanImproved localization accuracy in stochastic super-resolution fluorescence microscopy by K-factor image deshadowingLocalization of a single fluorescent particle with sub-diffraction-limit accuracy is a key merit in localization microscopy. Existing methods such as photoactivated localization microscopy (PALM) and stochastic optical reconstruction microscopy (STORM) achieve localization accuracies of single emitt...2014-01-01
14 Jorgensen, ErikImproved Mos1-mediated transgenesis in C. elegansThe ability to add or delete genes to the genome of genetic model organisms is essential. Previously, we developed methods based on the Mos1 transposon1 to make targeted transgene insertions (Mos1-mediated Single Copy transgene Insertions, MosSCI2) and targeted deletions (Mos1-mediated deletions, Mo...2012-01-01
15 Minteer, Shelley D.Improved performance of a thylakoid bio-solar cell by incorporation of carbon quantum dotsCarbon quantum dots (CQDs) were incorporated into thylakoid bioanodes capable of direct photobioelectrocatalysis in order to increase the photocurrent generation. More thylakoids are in contact with the increased surface area which allows for greater direct electron transfer (DET). Additionally, the...2014-01-01
16 Adler, Frederick R.Long-term models of oxidative stress and mitochondrial damage in insulin resistance progressionInsulin resistance, characterized by a reduced cellular response to insulin, is a major factor in type 2 diabetes pathogenesis, with a complex etiology consisting of a combination of environmental and genetic factors. Oxidative stress, which develops through an accumulation of toxic reactive oxygen ...2014-01-01
17 Beckerle, Mary C.LIM proteins in actin cytoskeleton mechanoresponseThe actin cytoskeleton assembles into branched networks or bundles to generate mechanical force for critical cellular processes such as establishment of polarity, adhesion, and migration.

18 Gondolo, PaoloLight dark matter in leptophobic Z' modelsRecent experimental results in direct dark matter detection may be interpreted in terms of a dark matter particle of mass around 10 GeV=c2. We show that the required scenario can be realized with a new dark matter particle charged under an extra Abelian gauge boson Z0 that couples to quarks but not ...2012-01-01
19 Sekercioglu, CaganThe effects of climate change on tropical birdsBirds are among the most widely studied organisms on earth and represent an important indicator group for learning about the effects of climate change - particularly in regard to the effects of climate change on tropical ecosystems.

20 Adler, Frederick R.Mathematical modeling the age dependence of Epstein-Barr virus associated infectious mononucleosisMost people get Epstein-Barr virus (EBV) infection at young age and are asymptomatic. Pri-mary EBV infection in adolescents and young adults however, often leads to infectious mononucleosis (IM) with symptoms including fever, fatigue, and sore throat that can persist for months. Expansion in the num...2012
21 Potts, Wayne K.MHC signaling during social communicationThe major histocompatibility complex (MHC) has been known to play a critical role in immune recognition since the 1950s. It was a surprise, then, in the 1970s when the first report appeared indicating MHC might also function in social signaling. Since this seminal discovery, MHC signaling has been f...2012-01-01
