Carbonate Orientational Order And Superlattice Structure In Vaterite, Jianwei Wang, Fuxiang Zhang, Jiaming Zhang, Rodney C. Ewing, Udo Becker, Zhonghou Cai
Faculty Publications
© 2014 Elsevier B.V. All rights reserved. Vaterite is considered to play an important role as a precursor phase in the formation of calcium carbonate phases, including those related to biomineralization. An accurate description of vaterite's structure associated with the order of carbonate groups is essential to understanding the formation, stabilization, and functionality of vaterite in organisms. Molecular dynamics simulations, synchrotron X-ray diffraction, and transmission electron microscopy have been combined in order to investigate the structure of vaterite. The electrostatic interactions between Ca and neighboring CO3 groups promote local and long-range ordering of CO3 groups, which may result in a …

Combined analyses of deep tow magnetic anomalies and International Ocean Discovery Program Expedition 349 cores show that initial seafloor spreading started around 33 Ma in the northeastern South China Sea (SCS), but varied slightly by 1-2 Myr along the northern continent-ocean boundary (COB). A southward ridge jump of ∼20 km occurred around 23.6 Ma in the East Subbasin; this timing also slightly varied along the ridge and was coeval to the onset of seafloor spreading in the Southwest Subbasin, which propagated for about 400 km southwestward from ∼23.6 to ∼21.5 Ma.

Review Of Methods To Assign The Nuclear Magnetic Resonance Peaks Of Reductively Methylated Proteins, Kevin J. Roberson, Megan A. Macnaughtan
Review Of Methods To Assign The Nuclear Magnetic Resonance Peaks Of Reductively Methylated Proteins, Kevin J. Roberson, Megan A. Macnaughtan
Faculty Publications
© 2014 Elsevier Inc. Reductive methylation of lysyl side-chain amines has been a successful tool in the advancement of high-resolution structural biology. The utility of this method has continuously gained ground as a protein chemical modification, first as a tool to aid protein crystallization and later as a probe in protein nuclear magnetic resonance (NMR) spectroscopy. As an isotope-labeling strategy for NMR studies, reductive methylation has contributed to the study of protein-protein interactions and global conformational changes. Although more detailed structural studies using this labeling strategy are possible, the hurdle of assigning the NMR peaks to the corresponding reductively methylated …

Message from President: Christmas, as it was called before it became a generic all-purpose “holiday,” is, at least in the propaganda of western cultures, all about universality: about the day when, so it seemed, the whole world lay at rest, when benefactions went out, if not to all mankind, at least to those on Santa’s good-person list. Christmas, indeed most any winter holiday, depends on the mass distribution of information: on everyone learning (a) that this is the day to keep calm and (b) what it is—what is the cultural and philosophical context—for at least a temporary peace. Everybody’s favorite …

The Roles Of The Shikimate Pathway Genes, Aroa And Arob, In Virulence, Growth And Uv Tolerance Of Burkholderia Glumae Strain 411gr-6, Hari Sharan Karki, Jong Hyun Ham
Faculty Publications
Burkholderia glumae is the major causal agent of bacterial panicle blight of rice, which is a growing disease problem for rice growers worldwide. In our previous study, some B.glumae strains showed pigmentation phenotypes producing at least two (yellow-green and purple) pigment compounds in casein-peptone-glucose agar medium. The B.glumae strains LSUPB114 and LSUPB116 are pigment-deficient mutant derivatives of the virulent and pigment-proficient strain 411gr-6, having mini-Tn5gus insertions in aroA encoding 3-phosphoshikimate 1-carboxyvinyltransferase and aroB encoding 3-dehydroquinate synthase, respectively. Both enzymes are known to be involved in the shikimate pathway, which leads to the synthesis of aromatic amino acids. Here, we demonstrate …

© 2014 by the authors; licensee MDPI, Basel, Switzerland. To fulfill the national bioenergy goals of the United States, conversion of marginal lands to intensive biomass crop production and/or application of greater amounts of nutrients to existing cropland could be expected. Such change in agricultural practices could produce unintended environmental consequences such as water quality degradation. Select Best Management Practices (BMPs) are evaluated for water quality mitigation effectiveness as well as for their relative cost-effectiveness, issues that are often ignored in evaluation of biofuels as a sustainable solution for energy demand. The water quality impacts of converting pastureland to intensive …

Daily distributions of eclosion and mating activities of Pseudopidorus fasciata Walker (Lepidoptera: Zygaenidae) were recorded under natural and various laboratory conditions. Eclosion of this insect exhibited circadian gating in constant darkness (DD) but not in constant light (LL) at 28°C. Under natural conditions, the majority of adults emerged in midmorning with an eclosion peak around 1000 hours. The eclosion distribution was significantly affected by ambient temperature but not by photoperiod under laboratory conditions. Eclosion was more spread out at 22°C than at higher temperatures, and peak eclosion times were advanced at higher temperatures up to 30°C. Under natural and laboratory …

Influence Of Rice Seeding Rate On Efficacies Of Neonicotinoid And Anthranilic Diamide Seed Treatments Against Rice Water Weevil, Jason Hamm, Srinivas Lanka, Michael Stout
Influence Of Rice Seeding Rate On Efficacies Of Neonicotinoid And Anthranilic Diamide Seed Treatments Against Rice Water Weevil, Jason Hamm, Srinivas Lanka, Michael Stout
Faculty Publications
© 2014 by the authors; licensee MDPI, Basel, Switzerland. Rice in the U.S. is frequently seeded at low rates and treated before sowing with neonicotinoid or anthranilic diamide insecticides to target the rice water weevil. A previous study of the influence of seeding rate on rice water weevil densities showed an inverse relationship between seeding rates and immature weevil densities. This study investigated interactive effects of seeding rate and seed treatment on weevil densities and rice yields; in particular, experiments were designed to determine whether seed treatments were less effective at low seeding rates. Four experiments were conducted over three …

© 2014. American Geophysical Union. All Rights Reserved. The evidence for sulfate-bearing strata, across Late-Noachian to Amazonian eons, suggests a central role for sulfates in acidity and salinity of Martian paleofluids and the planet's habitability. However, details remain unclear owing to shallow sampling and the limited ability of visible/near-infrared spectroscopy to distinguish among some sulfates. Using chemical data from the Mars Odyssey gamma ray spectrometer, including the sulfur map of Mars, we confirm the possibility of hydrous sulfates acting as key hydrates throughout the southern midlatitudinal soil at decimeter depths. An H2O:S molar ratio between 2.4 and 4.0 for 80% …

Photoheterotrophic Growth Of Physcomitrella Patens, Terry M. Bricker, Adam J. Bell, Lan Tran, Laurie K. Frankel, Steven M. Theg
Faculty Publications
© Springer-Verlag Berlin Heidelberg 2013. Physcomitrella patens is a model bryophyte representing an early land plant in the green plant lineage. This organism possesses many advantages as a model organism. Its genome has been sequenced, its predominant life cycle stage is the haploid gametophyte, it is readily transformable and it can integrate transformed DNA into its genome by homologous recombination. One limitation for the use of P. patens in photosynthesis research is its reported inability to grow photoheterotrophically, in the presence of sucrose and the Photosystem II inhibitor 3-(3,4-dichlorophenyl)-1,1-dimethylurea, which prevents linear photosynthetic electron transport. In this communication we describe …

We report the nonequilibrium behavior of disordered superconducting Al films in high Zeeman fields. We have measured the tunneling density of states of the films through the first-order Zeeman critical field transition. We find that films with sheet resistances of a few hundred ohms exhibit large avalanchelike collapses of the condensate on the superheating branch of the critical field hysteresis loop. In contrast, the transition back into the superconducting phase (i.e., along the supercooling branch) is always continuous. The fact that the condensate follows an unstable trajectory to the normal state suggests that the order parameter in the hysteretic regime …
Resonant Faraday And Kerr Effects Due To In-Gap States On The Surface Of A Topological Insulator, Justin H. Wilson, Dmitry K. Efimkin, Victor M. Galitski
Resonant Faraday And Kerr Effects Due To In-Gap States On The Surface Of A Topological Insulator, Justin H. Wilson, Dmitry K. Efimkin, Victor M. Galitski
Faculty Publications
When Dirac electrons on the surface of a topological insulator are gapped, the resulting quantum anomalous Hall effect leads to universal magneto-optical Faraday and Kerr effects in the low-frequency limit. However, at higher frequencies different excitations can leave their own fingerprints on the magneto-optics and can therefore be probed. In particular, we investigate the role of localized in-gap states - which inevitably appear in the presence of charged impurities - on these higher-frequency magneto-optical effects. We have shown that these states resonantly contribute to the Hall conductivity and are magneto-optically active. These in-gap states lead to peculiar resonant signatures in …

© 2014 Macmillan Publishers Limited. All rights reserved. Since the recognition that allopatric speciation can be induced by large-scale reconfigurations of the landscape that isolate formerly continuous populations, such as the separation of continents by plate tectonics, the uplift of mountains or the formation of large rivers, landscape change has been viewed as a primary driver of biological diversification. This process is referred to in biogeography as vicariance. In the most species-rich region of the world, the Neotropics, the sundering of populations associated with the Andean uplift is ascribed this principal role in speciation. An alternative model posits that rather …

Mechanical Expansion Of Steel Tubing As A Solution To Leaky Wellbores, Mileva Radonjic, Darko Kupresan
Faculty Publications
Wellbore cement, a procedural component of wellbore completion operations, primarily provides zonal isolation and mechanical support of the metal pipe (casing), and protects metal components from corrosive fluids. These are essential for uncompromised wellbore integrity. Cements can undergo multiple forms of failure, such as debonding at the cement/rock and cement/metal interfaces, fracturing, and defects within the cement matrix. Failures and defects within the cement will ultimately lead to fluid migration, resulting in inter-zonal fluid migration and premature well abandonment. Currently, there are over 1.8 million operating wells worldwide and over one third of these wells have leak related problems defined …

To counter the threat of insect resistance, Bacillus thuringiensis (Bt) maize growers in the U.S. are required to plant structured non-Bt maize refuges. Concerns with refuge compliance led to the introduction of seed mixtures, also called RIB (refuge-inthe-bag), as an alternative approach for implementing refuge for Bt maize products in the U.S. Maize Belt. A major concern in RIB is cross-pollination of maize hybrids that can cause Bt proteins to be present in refuge maize kernels and negatively affect refuge insects. Here we show that a mixed planting of 5% nonBt and 95% Bt maize containing the SmartStax traits expressing …

© 2014 Biophysical Society. Long-term storage of desiccated nucleated mammalian cells at ambient temperature may be accomplished in a stable glassy state, which can be achieved by removal of water from the biological sample in the presence of glass-forming agents including trehalose. The stability of the glass may be compromised due to a nonuniform distribution of residual water and trehalose within and around the desiccated cells. Thus, quantification of water and trehalose contents at the single-cell level is critical for predicting the glass formation and stability for dry storage. Using Raman microspectroscopy, we estimated the trehalose and residual water contents …

We report the results of a multimessenger search for coincident signals from the LIGO and Virgo gravitational-wave observatories and the partially completed IceCube high-energy neutrino detector, including periods of joint operation between 2007-2010. These include parts of the 2005-2007 run and the 2009-2010 run for LIGO-Virgo, and IceCube's observation periods with 22, 59 and 79 strings. We find no significant coincident events, and use the search results to derive upper limits on the rate of joint sources for a range of source emission parameters. For the optimistic assumption of gravitational-wave emission energy of 10-2M c2 at ∼150Hz with ∼60ms duration, …

Evolution of insect resistance to transgenic crops containing Bacillus thuringiensis (Bt) genes is a serious threat to the sustainability of this technology. However, field resistance related to the reduced efficacy of Bt maize has not been documented in any lepidopteran pest in the mainland U.S. after 18 years of intensive Bt maize planting. Here we report compelling evidence of field resistance in the fall armyworm, Spodoptera frugiperda (J.E. Smith), to Cry1F maize (TC 3507) in the southeastern region of the U.S. An F2 screen showed a surprisingly high (0.293) Cry1F resistance allele frequency in a population collected in 2011 from …

Lipoxygenases (LOX) play critical roles in mammalian biology in the generation of potent lipid mediators of the inflammatory response; consequently, they are targets for the development of isoform-specific inhibitors. The regio- and stereo-specificity of the oxygenation of polyunsaturated fatty acids by the enzymes is understood in terms of the chemistry, but structural observation of the enzyme-substrate interactions is lacking. Although several LOX crystal structures are available, heretofore the rapid oxygenation of bound substrate has precluded capture of the enzyme-substrate complex, leaving a gap between chemical and structural insights. In this report, we describe the 2.0 Å resolution structure of 8R-LOX …

A classical nova occurs when material accreting onto the surface of a white dwarf in a close binary system ignites in a thermonuclear runaway. Complex structures observed in the ejecta at late stages could result from interactions with the companion during the common-envelope phase. Alternatively, the explosion could be intrinsically bipolar, resulting from a localized ignition on the surface of the white dwarf or as a consequence of rotational distortion. Studying the structure of novae during the earliest phases is challenging because of the high spatial resolution needed to measure their small sizes. Here we report near-infrared interferometric measurements of …
