Coronal Mass Ejection Research Group

We determine the three-dimensional geometry and deprojected mass of 29 well-observed coronal mass ejections (CMEs) and their interplanetary counterparts (ICMEs) using combined Solar Terrestrial Relations Observatory - Solar and Heliospheric Observatory white-light data. From the geometry parameters, we calculate the volume of the CME for the magnetic ejecta (flux-rope type geometry) and sheath structure (shell-like geometry resembling the (I)CME frontal rim). Working under the assumption that the CME mass is roughly equally distributed within a specific volume, we expand the CME self-similarly and calculate the CME density for distances close to the Sun (15–30 Rs) and at 1 AU. Specific …

Lizard And Frog Removal Increases Spider Abundance But Does Not Cascade To Increase Herbivory, Karen H. Beard, Susan L. Durham, Michael R. Willig, Jess K. Zimmerman Dec 2020

Lizard And Frog Removal Increases Spider Abundance But Does Not Cascade To Increase Herbivory, Karen H. Beard, Susan L. Durham, Michael R. Willig, Jess K. Zimmerman

Wildland Resources Faculty Publications

Insectivorous vertebrates, especially on islands, can exert top-down control on herbivorous prey, which can transfer through a food chain to reduce herbivory. However, in many systems insectivorous vertebrates feed on more than one trophic level, especially consuming arthropod predators, and this intraguild predation can diminish trophic cascades. Our goal was to determine, using an exclosure experiment, the relative importance of anole lizards and coqui frogs in controlling spider and arthropod abundances as well as herbivory rates in the understory of the Luquillo Experimental Forest, Puerto Rico. We found that exclosures removing both anoles and coquis doubled spider abundance compared to …

Virtual Trials: Necessity, Invention, And The Evolution Of The Courtroom, Susan A. Bandes, Neal Feigenson Dec 2020

Virtual Trials: Necessity, Invention, And The Evolution Of The Courtroom, Susan A. Bandes, Neal Feigenson

Buffalo Law Review

Faith in the legitimating power of the live hearing or trial performed at the place of justice is at least as old as the Iliad. In public courtrooms, litigants appear together, evidence is presented, and decisions are openly and formally pronounced. The bedrock belief in the importance of the courtroom is rooted in common law, constitutional guarantees, and venerated tradition, as well as in folk knowledge. Courtrooms are widely believed to imbue adjudication with “a mystique of authenticity and legitimacy.” The COVID-19 pandemic, however, by compelling legal systems throughout the world to turn from physical courtrooms to virtual ones, disrupts …

Local Injections Of Β-Ngf Accelerates Endochondral Fracture Repair By Promoting Cartilage To Bone Conversion., Kevin O. Rivera, Fabrizio Russo, Ryan M. Boileau, Ryan E. Tomlinson, Theodore Miclau, Ralph S. Marcucio, Tejal A. Desai, Chelsea S. Bahney

Department of Orthopaedic Surgery Faculty Papers

There are currently no pharmacological approaches in fracture healing designed to therapeutically stimulate endochondral ossification. In this study, we test nerve growth factor (NGF) as an understudied therapeutic for fracture repair. We first characterized endogenous expression of Ngf and its receptor tropomyosin receptor kinase A (TrkA) during tibial fracture repair, finding that they peak during the cartilaginous phase. We then tested two injection regimens and found that local β-NGF injections during the endochondral/cartilaginous phase promoted osteogenic marker expression. Gene expression data from β-NGF stimulated cartilage callus explants show a promotion in markers associated with endochondral ossification such as Ihh, Alpl, …

Native And Non-Native Sources Of Carbohydrate Correlate With Abundance Of An Invasive Ant, Lori Lach, Benjamin Hoffmann, Melinda L. Moir Dec 2020

Native And Non-Native Sources Of Carbohydrate Correlate With Abundance Of An Invasive Ant, Lori Lach, Benjamin Hoffmann, Melinda L. Moir

Biosecurity Research Articles

Invasive species threaten many ecological communities and predicting which communities and sites are invasible remains a key goal of invasion ecology. Although invasive ants often reach high abundances in association with plant-based carbohydrate resources, the source and provenance of these resources are rarely investigated. We characterized carbohydrate resources across ten sites with a range of yellow crazy ant abundance in Arnhem Land, Australia and New Caledonia to determine whether yellow crazy ant (Anoplolepis gracilipes) abundance and trophic position correlate with carbohydrate availability, as well as the relative importance of native and non-native sources of carbohydrates to ant diet. …

Sea Otter Diet Composition With Respect To Recolonization, Life History, And Season In Southern Southeast Alaska, Nicole Laroche Dec 2020

Sea Otter Diet Composition With Respect To Recolonization, Life History, And Season In Southern Southeast Alaska, Nicole Laroche

Fisheries

Until translocation efforts in the 1960s, sea otters (Enhydra lutris) were absent from Southeast Alaska due to extirpation by the fur trade in the 18th and 19th centuries. About 400 sea otters were reintroduced to six Southeast Alaska locations, including two sites near Prince of Wales Island in southern Southeast Alaska. The most recent US Fish and Wildlife Service population count, completed in 2012, estimated that about 25,000 sea otters inhabited Southeast Alaska. Sea otters will reduce invertebrate prey biomass when recolonizing an area. By quantifying sea otter diets and caloric intake according to recolonization patterns, we can better understand …

Genomic Signatures Of Optimal Growth Temperature In The Family Colwelliaceae, Anais Gentilhomme Dec 2020

Genomic Signatures Of Optimal Growth Temperature In The Family Colwelliaceae, Anais Gentilhomme

Oceanography

The temperature range supporting growth defines a complex physiological phenotype that depends on interactions between an organism's genome and its environment. Its implications are widespread since small changes in optimal growth temperature (OGT) can alter an organism's ability to inhabit an ecological niche. Thus, organisms with extreme thermal growth traits (e.g., psychrophilic, with OGT < 15℃, or thermophilic, with OGT 60 -80℃) may be useful for identifying promising targets when searching for life on other planets, as well as predicting population dynamics in a warming Arctic. We performed comparative genomic analyses of bacteria newly isolated from Arctic sea ice that were affiliated with Colwelliaceae, a family of Gammaproteobacteria that contains many psychrophilic strains, to identify genomic factors that might be used to predict OGT. A phylogenomic analysis of 67 public and 39 newly-sequenced strains, was used to construct an updated phylogenetic tree of Colwelliaceae, of which at least two genera were well represented. To augment the previously reported OGTs of 26 strains, we measured growth rates at −1, 4, 11, and 17 ℃ to determine the OGTs of these 39 new strains of Colwelliaceae. We found that growth rates among all isolates were comparable at −1℃, but varied widely above 10 ℃, indicating higher variability in the ability to tolerate warmer temperatures. To analyze the phenotypic differences on a genomic level, we examined indices of amino acid substitutions that have previously been linked with cold adaptation via an increase in protein flexibility. We found that these indices were significantly correlated with OGT at the whole genome level, although the sign of some correlations were opposite of the predicted positive correlation between temperature and the indices. Using these data, we fit a multiple linear regression model for OGT within the Colwelliaceae family that incorporates the three most informative amino acid indices: GRAVY, Aliphatic Index, and Acidic Residue Proportion. Additionally, a putative cold-adaptive gene cassette was identified that was likely introduced by horizontal gene transfer between two closely related clades with different OGTs. These contributions offer key insights into OGT variability and its underlying genomic foundation in the family Colwelliaceae.

Review And Case Study Of Electric Submersible Pump Performance With Dispersions, Dexter Bryant Ellexson Dec 2020

Review And Case Study Of Electric Submersible Pump Performance With Dispersions, Dexter Bryant Ellexson

Engineering

Centrifugal pump performance is very sensitive to fluid viscosity, gas fraction, and flow pattern in impeller channels. Viscous oil reduces the head and rate capacity of the pump. High gas fraction reduces the head capacity of the pump at high rates and leads to unstable surging at low rates. If the flow pattern in the impeller transitions to an elongated bubble the pump can gas-lock causing loss of production and excessive heat buildup. The complex geometry and 3-dimensional flow in a pump stage make the analysis of flow in a pump difficult without simplifying assumptions. Empirical and mechanistic models have …

Efficient Alternative Food Systems For Earth And Space, Kyle A. Alvarado

Engineering

Alternative foods are a source of human-edible calories derived from an unconventional source or process. This thesis includes two alternative foods: (i) crops grown under low-tech greenhouses in low sunlight environments and (ii) hydrogen-oxidizing bacteria (HOB) in space and Earth refuges, such as to repopulate the Earth. The purpose of alternative foods is to ensure food security for human survival. During a global catastrophic risk (GCR) scenario, such as nuclear winter or super volcanic eruption, the sun may be obscured, causing lack of crop production and therefore global food shortages. The purpose of this thesis was to improve the cost …
