Local Filters Limit Species Diversity, But Species Pools Determine Composition, Tara K. Rajaniemi, Deborah E. Goldberg, Roy Turkington, Andrew R. Dyer

Faculty Publications

In a series of three experiments, we tested for effects of species pools, resource stress, and species interactions on four aspects of community structure: species richness, evenness, species composition, and functional group composition. We also examined whether the impacts of species interactions on the community varied with resource availability or species pool. Communities of sand dune annuals grew from seed bank samples collected from two sites in three different years, so that the species pool differed at two levels: the source site and the year of seed bank collection. Communities experienced one of three irrigation treatments and a range of …

High Performance Low Temperature Solid Oxide Fuel Cells With Novel Electrode Architecture, Yu Chen, Qian Liu, Zhibin Yang, Fanglin Chen, Minfang Han

Faculty Publications

In this study, we have fabricated high performance low temperature solid oxide fuel cells (LT-SOFCs) with both acicular anodes and cathodes with thin Gd-doped ceria (GDC) electrolyte film. The acicular Ni-Gd_0.1Ce_0.9O_2−δ (Ni-GDC) anode was prepared using freeze drying tape casting, while the hierarchically porous cathode with nano-size Sm_0.5Sr_0.5CoO₃ (SSC) particles covering an acicular GDC skeleton was prepared by a combination of freeze drying tape casting and self-rising approaches. The acicular electrodes with 5–200 μm pores/channels enhance mass transport, while SSC particles of about 50 nm in the cathode promote …

Dissolved Organic Matter Composition And Bioavailability Reflect Ecosystem Productivity In The Western Arctic Ocean, Yuan Shen, Cedric Fichot, Ronald Benner

Faculty Publications

Dissolved organic carbon (DOC) and total dissolved amino acids (TDAA) were measured in high (Chukchi Sea) and low (Beaufort Sea) productivity regions of the western Arctic Ocean to investigate the composition and bioavailability of dissolved organic matter (DOM). Concentrations and DOC-normalized yields of TDAA in Chukchi surface waters were relatively high, indicating an accumulation of bioavailable DOM. High concentrations and yields of TDAA were also observed in the upper halocline of slope and basin waters, indicating off-shelf transport of bioavailable DOM from the Chukchi Sea. In contrast, concentrations and yields of TDAA in Beaufort surface waters were relatively low, indicting …

Prevalence And Predictors Of Giving Birth In Health Facilities In Bugesera District, Rwanda, Shahrzad Joharifard, Stephen Rulisa, Francine Niyonkuru, Andrew Weinhold, Felix Sayinzoga, Jeffrey Wilkinson, Jan Ostermann, Nathan M. Thielman

Faculty Publications

Background The proportion of births attended by skilled health personnel is one of two indicators used to measure progress towards Millennium Development Goal 5, which aims for a 75% reduction in global maternal mortality ratios by 2015. Rwanda has one of the highest maternal mortality ratios in the world, estimated between 249–584 maternal deaths per 100,000 live births. The objectives of this study were to quantify secular trends in health facility delivery and to identify factors that affect the uptake of intrapartum healthcare services among women living in rural villages in Bugesera District, Eastern Province, Rwanda.

Civil Rights, Charter Schools, And Lessons To Be Learned, Derek W. Black

Faculty Publications

Two major structural shifts have occurred in education reform in the past two decades: the decline of civil rights reforms and the rise of charter schools. Courts and policy makers have relegated traditional civil rights reforms that address segregation, poverty, disability, and language barriers to near irrelevance, while charter schools and policies supporting their creation and expansion have rapidly increased and now dominate federal policy. Advocates of traditional civil rights reforms interpret the success of charter schools as a threat to their cause, and, consequently, have fought the expansion of charter schools. This Article argues that the civil rights community …

Coupling Right- And Left-Handed Photons Differently To Charged Matter, Brett David Altschul

Faculty Publications

We consider a modification of electrodynamics in which right- and left-circularly polarized photons are coupled to charged sources differently. Even though photon helicity is a Lorentz invariant quantity, such a modification breaks Lorentz symmetry, as well as locality. The modified theory includes novel magnetic forces between perpendicular currents. Existing data can be used to constrain the modification at approximately a 2 x 10^(-3) level.

Inside Voices: Protecting The Student-Critic In Public Schools, Josie F. Brown

Faculty Publications

First Amendment doctrine acknowledges the constructive potential of citizens’ criticism of public officials and governmental policies by offering such speech vigilant protection. However, when students speak out about perceived injustice or dysfunction in their public schools, teachers and administrators too often react by squelching and even punishing student-critics. To counteract school officials’ reflexively repressive responses to student protest and petition activities, this Article explains why the faithful performance of public schools’ responsibility to prepare students for constitutional citizenship demands the adoption of a more receptive and respectful attitude toward student dissent. After documenting how both educators and courts have mistakenly …

The Archeology Of Civil War Naval Operations At Charleston Harbor, South Carolina, 1861-1865, James D. Spirek

Mechanically Robust Si Nanorod Arrays On Cu/Ti Bilayer Film Coated Si Substrate For High Performance Lithium-Ion Battery Anodes, Yingchao Yang

Faculty Publications

The deformation behavior and mechanical properties of a tilted Si nanorod array structure on Cu/Ti bilayer film coated Si substrate were studied for the first time by coupled atomic force microscopy and nanoindentation techniques. The individual Si nanorods fabricated by an oblique angle deposition technique are composed of many fine Si nanofibers with the diameter ranging from 10 to 50 nm. They are not brittle, but ductile. The ductile metallic Cu/Ti bilayer film roots contribute remarkably to the mechanical robustness of the Si nanorods. The toughening mechanism of such Si-based nanoanodes has been elucidated by experimental mechanics studies.

Complex Of Myoglobin With Phenol Bound In A Proximal Cavity, Xiao Huang, Chunxue Wang, Lesa R. Celeste, Leslie L. Lovelace, Shengfang Sun, John H. Dawson, Lukasz Lebioda

Faculty Publications

Sperm whale myoglobin (Mb) has weak dehaloperoxidase activity and catalyzes the peroxidative dehalogenation of 2,4,6-trichlorophenol (TCP) to 2,6-dichloroquinone. Crystals of Mb and of its more active G65T variant were used to study the binding of TCP, 4-iodophenol (4-IP) and phenol. The structures of crystals soaked overnight in a 10 mM solution of phenol revealed that a phenol molecule binds in the proximal cavity, forming a hydrogen bond to the hydroxyl of Tyr146 and hydrophobic contacts which include interactions with C and C of the proximal histidine His93. The phenol position corresponds to the strongest xenon binding site, Xe1. It …

Maternal Pre‐Pregnancy Body Mass Index Is Not Associated With Infant And Young Child Feeding In Low‐Income Mexican Children 1–24 Months Old, Eva C. Monterrosa, Edward A. Frongillo Jr., Lynnette M. Neufeld, Kelsey A. Egan, Usha Ramakrishnan, Kathleen M. Rasmussen

Faculty Publications

Pre-pregnancy overweight and obesity is associated with shorter breastfeeding (BF) duration. Whether pre-pregnancy overweight and obesity is associated with other aspects of infant and young child feeding (IYCF) hasnot been investigated. We used data from 370 children born January 1999–September 2001 in a semi-urbancommunity in Morelos, Mexico, where information on how they were fed was available at 1, 3, 6, 9, 12, 18 and 24months of age. We modified the World Health Organization’s dietary diversity indicator to assess the quality ofthe complementary foods. An index that included BF, quality of complementary foods and other behaviours wasconstructed to measure IYCF. We …

Quantum Effects Of A Spacetime Varying Alpha On The Propagation Of Electrically Charged Fermions, Alejandro Ferrero, Brett David Altschul

Faculty Publications

A spacetime-varying fine structure constant α(x ^µ) could generate quantum corrections in some of the coefficients of the Lorentz-violating standard model extension (SME) associated with electrically charged fermions. The quantum corrections depend on ∂µα, the spacetime gradient of the fine structure constant. Lorentz-violating operators involving fermions arise from the one-loop corrections to the quantum electrodynamics (QED) vertex function and fermion self-energy. Both g λµν and c µν terms are generated, at O(∂_µα) and O[(∂_{µα) ² ], respectively. The g λµν terms so generated are different in the vertex and self-energy, which represents a radiatively induced violation …}

Atomistic Investigation Of Scratching-Induced Deformation Twinning In Nanocrystalline Cu, Junjie Zhang, Tao Sun, Yoganda Yan, Dong Shen, Xiaodong Li

Faculty Publications

Deformation twinning is an important deformation mode of nanocrystalline metals. In current study, we investigate the scratching-induced deformation twinning in nanocrystallineCu by means of molecular dynamics simulations. The tribological behavior, the deformation mechanisms, the formation mechanism of deformation twins, and the grain size dependence of the propensity of deformation twinning are elucidated. Simulation results demonstrate that deformation twinning plays an important role in the plastic deformation of nanocrystallineCu under nanoscratching, in addition to dislocation activity and grain boundary-associated mechanism. The nucleation of initial twinning partial dislocations originates from the dissociation of lattice partial dislocations that emit from grain boundary triple …
