| 6 | Sulfidation and selenidation of nickel nanoparticles显示文摘NPs using elemental sulfur,1-hexadecanthiol,thiourea,trioctylphosphine sulfide,elemental selenium,and selenourea.While maintaining mole ratios of 2 mmol sulfur/selenium precursor:mmol Ni,products with phases of Ni_(3)S_(2),Ni_(9)S_(8),NiS,NiSO_(4)·6H_(2)O,Ni_(3)S_(4),Ni_(3)Se_(2),and NiSe have been obtained.The products have voids that form through the Kirkendall effect during interdiffusion.Trends relating the chemical properties of the precursors to the phases of the products have been identified.While some precursors contained phosphorus,there was no significant incorporation of phosphorus in any of the products.An increase of the NP size during sulfidation and selenidation is consistent with ripening.The application of Ni sulfide and selenide NPs as electrocatalysts for the hydrogen evolution reaction is also demonstrated. | Brian B.Lynch Andrew P.Kelliher Bryan D.Anderson Alexander Japit Michael A.Spencer Mehedi H.Rizvi Mehmet F.Sarac Veronica Augustyn Joseph B.Tracy | 2021 | Carbon Energy2021,3,4: | 1 |

| 11 | Sequencing and comparative analyses of Aegilops tauschii chromosome arm 3DS reveal rapid evolution of Triticeae genomes显示文摘Bread wheat(Triticum aestivum,AABBDD) is an allohexaploid species derived from two rounds of interspecific hybridizations.A high-quality genome sequence assembly of diploid Aegilops tauschii,the donor of the wheat D genome,will provide a useful platform to study polyploid wheat evolution.A combined approach of BAC pooling and next-generation sequencing technology was employed to sequence the minimum tiling path(MTP) of 3176 BAC clones from the short arm of Ae.tauschii chromosome 3(At3DS).The final assembly of 135 super-scaffolds with an N50 of 4.2 Mb was used to build a247-Mb pseudomolecule with a total of 2222 predicted protein-coding genes.Compared with the orthologous regions of rice,Brachypodium,and sorghum,At3 DS contains 38.67%more genes.In comparison to At3 DS,the short arm sequence of wheat chromosome 3B(Ta3BS) is 95-Mb large in size,which is primarily due to the expansion of the non-centromeric region,suggesting that transposable element(TE) bursts in Ta3 B likely occurred there.Also,the size increase is accompanied by a proportional increase in gene number in Ta3 BS.We found that in the sequence of short arm of wheat chromosome 3D(Ta3DS),there was only less than 0.27%gene loss compared to At3 DS.Our study reveals divergent evolution of grass genomes and provides new insights into sequence changes in the polyploid wheat genome. | Jingzhong Xie Naxin Huo Shenghui Zhou Yi Wang Guanghao Guo Karin R.Deal Shuhong Ouyang Yong Liang Zhenzhong Wang Lichan Xiao Tingting Zhu Tiezhu Hu Vijay Tiwari Jianwei Zhang Hongxia Li Zhongfu Ni Yingyin Yao Huiru Peng Shengli Zhang Olin D.Anderson Patrick E.McGuire Jan Dvorak Ming-Cheng Luo Zhiyong Liu Yong Q.Gu Qixin Sun | 2017 | Journal of Genetics and Genomics2017,44,1: | 1 |
| 12 | Saturn's gravitational field induced by its equatorially antisymmetric zonal winds显示文摘The cloud-level zonal winds of Saturn are marked by a substantial equatorially antisymmetric component with a speed of about 50 m s-1 which, if they are sufficiently deep, can produce measurable odd zonal gravitational coefficients ?J2 k+1, k = 1, 2, 3, 4. This study, based on solutions of the thermal-gravitational wind equation, provides a theoretical basis for interpreting the odd gravitational coefficients of Saturn in terms of its equatorially antisymmetric zonal flow. We adopt a Saturnian model comprising an ice-rock core, a metallic dynamo region and an outer molecular envelope. We use an equatorially antisymmetric zonal flow that is parameterized, confined in the molecular envelope and satisfies the solvability condition required for the thermal-gravitational wind equation. The structure and amplitude of the zonal flow at the cloud level are chosen to be consistent with observations of Saturn.We calculate the odd zonal gravitational coefficients ?J_(2k+1), k = 1, 2, 3, 4 by regarding the depth of the equatorially antisymmetric winds as a parameter. It is found that ?J_3 is-4.197 × 10^(-8) if the zonal winds extend about 13 000 km downward from the cloud tops while it is-0.765 × 10^(-8) if the depth is about 4000 km. The depth/profile of the equatorially antisymmetric zonal winds can eventually be estimated when the high-precision measurements of the Cassini Grand Finale become available. | Dali Kong Keke Zhang Gerald Schubert John D.Anderson | 2018 | Research in Astronomy and Astrophysics2018,18,5: | 0 |
| 13 | Identification of habitat controls on northern red-legged frog populations: implications for habitat conservation on an urbanizing landscape in the Pacific Northwest显示文摘Introduction: In the Pacific Northwest of North America, research addressing lentic-breeding amphibian populationvulnerability has emphasized aquatic habitats, frequently neglecting terrestrial habitats. Consequently, wetlandprotection and restoration often fails to preserve or restore adjacent uplands required by lentic-breeding amphibians.Inattention to the juxtaposition and connectivity of uplands to wetlands could locally extirpate lentic-breedingamphibians. The objective of this research is to identify the relative importance of juxtaposed terrestrial and aquatichabitats in a lentic-breeding amphibian, the northern red-legged frog (Rana aurora), by evaluating the relationshipbetween its occurrence and abundance with its aquatic and terrestrial habitats. To accomplish this, egg mass countswere used to quantify R. aurora populations in 30 stillwater habitats across an urbanization gradient. Using aGeographic Information System, seven descriptors of aquatic and surrounding terrestrial habitats were measured toevaluate their relationships to R. aurora occurrence and abundance.Results: Rana aurora occurrence and breeding abundance both reflect the forested area around wetland breedingsites and forest connectivity to those sites. Rana aurora breeding abundance also strongly reflects the percent offorested perimeter around wetland breeding sites. The forest habitat most important for R. aurora breeding abundanceseems to be > 200 m from the breeding wetlands. The American bullfrog presence and the two aquatic parametersmeasured, wetland area and vegetated area, were unrelated to R. aurora occurrence and breeding abundance.Conclusions: Area and connectivity of juxtaposed forested terrestrial habitat may represent a basic control on R. aurorapresence and population size. Urban development policies should consider preservation and restoration of uplandforest habitats beyond current fixed-width buffers and wetland habitat area at landscape scales. | Lauren A.Grand Marc P.Hayes Kristiina A.Vogt Daniel J.Vogt Paul R.Yarnold Klaus O.Richter Christopher D.Anderson Elissa C.Ostergaard Jo O.Wilhelm | 2017 | Ecological Processes2017,6,1: | 0 |

| 15 | Trends of seasonal forage yield changes of triticale in the southern Great Plains of the United States显示文摘Background:The focus of triticale breeding in the southern Great Plains of the United States has been to increase forage yield for autumn-winter seasons when most other forage species are dormant.This study aims to estimate the trends of seasonal yield changes over time.Methods:Yield trials had been conducted in a randomized complete block design for up to two decades.Seasonal yield changes over time were estimated using linear regression analysis.Results:The analysis revealed a significant positive relation between autumn forage yield(relative to common checks)and calendar years when the trials were conducted.The estimated improvement of autumn forage yield was about 1.9%per year on medium and heavy soil at Ardmore,Oklahoma,and about 5.4%per year on light soil at Burneyville,Oklahoma.However,winter forage yield change was minimal and the spring forage yield increase was negative,although this decline was not significant.Total forage yield improvements were about 0.6%and 0.7%per year at Ardmore and Burneyville,respectively.Similar results were also observed when years of cultivars'introduction were used instead.Conclusions:The results indicate a significant gain in autumn forage yield,but a minor gain in the total forage yield due to the yield tradeoff between the autumn and spring seasons. | Tadele T.Kumssa Joshua D.Anderson James P.Johnson Shawn Norton Malay C.Saha Michael A.Trammell James K.Rogers Twain J.Butler Xue-Feng Ma | 2022 | Grassland Research2022,1,3: | 0 |
| 16 | 卷帘式彩色LCoS显示器的对比度改善显示文摘卷帘式彩色LCoS(硅上液晶)显示必须展现其快速和高对比度两项特性。这些要求推动了成像核心的液晶和光学系统的设计选择。我们发现,输入方向必须沿着入射偏振方向,且须选择一种补偿性的45TN0效应。高对比度需要对界面反射提出严格的要求。线栅PBS能实现高的对比度且能简化系统结构。在关注上述问题的同时,我们曾报告过,在视屏上的时序对比度为8001。采用90TN0效应,其对比度可以更高,但会有一些光效损失。采用这种效应所测时序对比度为20001。 | J.A.Shimizu P.Janssen S.Yakovenko D.Anderson 柳玉华 徐康兴 | 2004 | 现代显示2004,,4: | 0 |
| 17 | A model of Saturn inferred from its measured gravitational field显示文摘We present an interior model of Saturn with an ice-rock core,a metallic region,an outer molecular envelope and a thin transition layer between the metallic and molecular regions.The shape of Saturn’s 1 bar surface is irregular and determined fully self-consistently by the required equilibrium condition.While the ice-rock core is assumed to have a uniform density,three different equations of state are adopted for the metallic,molecular and transition regions.The Saturnian model is constrained by its known mass,its known equatorial and polar radii,and its known zonal gravitational coefficients,J_(2n),n=1,2,3.The model produces an ice-rock core with equatorial radius 0.203 R_S,where R_S is the equatorial radius of Saturn at the 1-bar pressure surface;the core densityρ_c=10388.1 kgm^(3)corresponding to 13.06 Earth masses;and an analytical expression describing the Saturnian irregular shape of the 1-bar pressure level.The model also predicts the values of the higher-order gravitational coefficients,J_8,J_10 and J_12,for the hydrostatic Saturn and suggests that Saturn’s convective dynamo operates in the metallic region approximately defined by 0.2 R_S | Dali Kong Keke Zhang Gerald Schubert John D.Anderson | 2018 | Research in Astronomy and Astrophysics2018,18,4: | 0 |
| 18 | The effect of the equatorially symmetric zonal winds of Saturn on its gravitational field显示文摘The penetration depth of Saturn’s cloud-level winds into its interior is unknown.A possible way of estimating the depth is through measurement of the effect of the winds on the planet’s gravitational field.We use a self-consistent perturbation approach to study how the equatorially symmetric zonal winds of Saturn contribute to its gravitational field.An important advantage of this approach is that the variation of its gravitational field solely caused by the winds can be isolated and identified because the leading-order problem accounts exactly for rotational distortion,thereby determining the irregular shape and internal structure of the hydrostatic Saturn.We assume that(i)the zonal winds are maintained by thermal convection in the form of non-axisymmetric columnar rolls and(ii)the internal structure of the winds,because of the Taylor-Proundman theorem,can be uniquely determined by the observed cloud-level winds.We calculate both the variation △J_n,n=2,4,6...of the axisymmetric gravitational coefficients J_n caused by the zonal winds and the non-axisymmetric gravitational coefficients △J_(nm) produced by the columnar rolls,where m is the azimuthal wavenumber of the rolls.We consider three different cases characterized by the penetration depth 0.36 R_S,0.2 R_S and 0.1 R_S,where R_S is the equatorial radius of Saturn at the 1-bar pressure level.We find that the high-degree gravitational coefficient ( J_(12)+△J_(12)) is dominated,in all the three cases,by the effect of the zonal flow with |△J_(12)/J_(12)|>100%and that the size of the non-axisymmetric coefficientsdirectly reflects the depth and scale of the flow taking place in the Saturnian interior. | Dali Kong Keke Zhang Gerald Schubert John D.Anderson | 2018 | Research in Astronomy and Astrophysics2018,18,4: | 0 |
