• #### Genomic Differentiation during Speciation-with-Gene-Flow: Comparing Geographic and Host-Related Variation in Divergent Life History Adaptation in Rhagoletis pomonella ﻿

(2018)
A major goal of evolutionary biology is to understand how variation within populations gets partitioned into differences between reproductively isolated species. Here, we examine the degree to which diapause life history ...
• #### Genomics-aided structure prediction ﻿

(2012)
We introduce a theoretical framework that exploits the everincreasing genomic sequence information for protein structure prediction. Structure-based models are modified to incorporate constraints by a large number of ...

(2012)
• #### Geographic and population variation in pollinating seed-consuming interactions between senita cacti (Lophocereus schottii) and senita moths (Upiga virescens) ﻿

(1999)
Interspecific interactions can vary within and among populations and geographic locations. This variation can subsequently influence the evolution and coevolution of species interactions. We investigated population and ...
• #### Geometric representation of spin correlations and applications to ultracold systems ﻿

(2018)
We provide a one-to-one map between the spin correlations and certain three-dimensional shapes, analogous to the map between single spins and Bloch vectors, and demonstrate its utility. Much as one can reason geometrically ...
• #### Geometrical confinement of Gd(DOTA) molecules within mesoporous silicon nanoconstructs for MR imaging of cancer ﻿

(2014)
Porous silicon has been used for the delivery of therapeutic and imaging agents in several biomedical applications. Here, mesoporous silicon nanoconstructs (SiMPs) with a discoidal shape and a sub-micrometer size (1,000 × ...
• #### Geometrical Frustration in Interleukin-33 Decouples the Dynamics of the Functional Element from the Folding Transition State Ensemble ﻿

(2015)
Interleukin-33 (IL-33) is currently the focus of multiple investigations into targeting pernicious inflammatory disorders. This mediator of inflammation plays a prevalent role in chronic disorders such as asthma, rheumatoid ...
• #### Germanium/silicon of the Ediacaran-Cambrian Laobao cherts: Implications for the bedded chert formation and paleoenvironment interpretations ﻿

(2015)
Sedimentary strata of the terminal Ediacaran (635–542 Ma) to early Cambrian (542–488 Ma) Laobao-Liuchapo bedded cherts in the South China Block include the Ediacaran Oxidation Event and the Cambrian explosion. Understanding ...
• #### Ghosts of Habitats Past: Environmental Carry-Over Effects Drive Population Dynamics in Novel Habitat ﻿

(2013-05)
The phenotype of adults can be strongly influenced by the environmental conditions experienced during development. Consequently, variation in habitat quality across space and through time also leads to differences in the ...
• #### Giant Terahertz-Wave Absorption by Monolayer Graphene in a Total Internal Reflection Geometry ﻿

(2017)
We experimentally demonstrated significant enhancement of terahertz-wave absorption in monolayer graphene by simply sandwiching monolayer graphene between two dielectric media in a total internal reflection geometry. In ...
• #### Giant tunable Faraday effect in a semiconductor magneto-plasma for broadband terahertz polarization optics ﻿

(2012)
We report on a giant Faraday effect in an electron plasma in n- InSb probed via polarization-resolved terahertz (THz) time-domain spectroscopy. Polarization rotation angles and ellipticities reach as large as π/2 and 1, ...
• #### Glacially generated overpressure on the New England continental shelf: Integration of full-waveform inversion and overpressure modeling ﻿

(2014)
Localized zones of high-amplitude, discontinuous seismic reflections 100 km off the coast of Massachusetts, USA, have P wave velocities up to 190 m/s lower than those of adjacent sediments of equal depth (250m below the ...
• #### Glide reflection symmetry, Brillouin zone folding, and superconducting pairing for the P4/nmm space group ﻿

(2015)
Motivated by the studies of the superconducting pairing states in the iron-based superconductors, we analyze the effects of Brillouin zone folding procedure from a space-group symmetry perspective for a general class of ...

(2010)
• #### Global MHD modeling of resonant ULF waves: Simulations with and without a plasmasphere ﻿

(2016)
We investigate the plasmaspheric influence on the resonant mode coupling of magnetospheric ultralow frequency (ULF) waves using the Lyon-Fedder-Mobarry (LFM) global magnetohydrodynamic (MHD) model. We present results from ...
• #### Global polarization of $\mathrm{\ensuremath{\Lambda}}$ hyperons in Au + Au collisions at $\sqrt{{s}_{NN}}=200$ GeV ﻿

(2018)
Global polarization of Λ hyperons has been measured to be of the order of a few tenths of a percentage in Au+Au collisions at √sNN = 200 GeV, with no significant difference between Λ and ¯¯¯Λ. These new results reveal the ...
• #### Gold coated iron phosphide core–shell structures ﻿

(2017)
Core–shell particles Fe2P@Au have been prepared beginning with Fe2P nanorods, nanocrosses and nanobundles prepared from the solvothermal decomposition of H2Fe3(CO)9(μ3-PtBu). Iron phosphide structures can be produced from ...
• #### Gold nanoparticles and radiofrequency in experimental models for hepatocellular carcinoma ﻿

(2014)
Hepatocellular carcinoma (HCC) is one of the most lethal and chemo-refractory cancers, clearly, alternative treatment strategies are needed. We utilized 10 nm gold nanoparticles as a scaffold to synthesize nanoconjugates ...
