Modeling Investigation Of Atmospheric Moisture Transport Over The North Pacific Ocean: Role Of Pacific Decadal Oscillation, Cecilia Borries, Xiangdong Zhang

Research Posters

Atmospheric moisture content over the North Pacific Ocean can fluctuate under the influence of the Pacific Decadal Oscillation (PDO). For a better understanding of the role which the PDO plays in the North Pacific water budgets and pathways, we conducted sensitivity experiments to examine how atmospheric moisture transport responds to sea surface temperature (SST) anomalies associated with the PDO phases transitions. This study has important implications for improving understanding of precipitation events in areas surrounding the North Pacific.

Modeling The Thermal Balance Between Groundwater Springs And River Ice, Chas Jones, Knut Kielland, Larry Hinzman

Research Posters

We modeled the thermal balance between groundwater discharge and ice-free areas in the Tanana River near Fairbanks, Alaska, a region that is characterized by discontinuous permafrost. Under degrading permafrost conditions, these areas have been hypothesized to have increased winter discharge due to increasing contributions from groundwater flow. In the winter, interior Alaskan rivers are fed almost entirely by groundwater, which also serves as an external source of heat energy to the system. Several reaches of the river fed by groundwater springs remain ice-free or have dangerously thin ice throughout the winter despite air temperatures that dip below -40° C. These …

Dynamic Interactions Of Snow And Plants In The Boreal Forest, Winter 2011-2012 Revealed By Time-Lapse Photography And Lidar, Simon Filhol, Matthew Sturm

Research Posters

As winter progresses, snow accumulates on the ground and plants of the boreal forest. On their passage to the ground, the falling snowflakes encounter physical obstacles like the complex structure of tree branches and shrubs. These cause the fall trajectories to deviate, and in some cases even stop, before a snowflake reaches the forest floor. After deposition, wind and gravitational settlement further affect the snow distribution. Because of these snow-vegetation interactions, snow gets distributed in the forest along vertical and the horizontal directions in a complex way. To better understand these interactions between snow and plants, we designed an experiment, …

Improve Ocean Mixing Caused By Subgrid-Scale Brine Rejection Using Multi-Column Ocean Grid In A Climate Model, Meibing Jin, Jennifer Hutchings, Yusuke Kawaguchi, Takashi Kikuchi

Research Posters

Heterogeneous ice pack with sporadic narrow but long leads in the polar oceans was unresolved in typical climate model grid. Although multi-category sea ice thickness distribution was used in one sea ice model grid to calculate separate heat, salt and tracer fluxes through each category, the ocean models use only single-column grid to communicate with the averaged fluxes from all categories. When the lead is resolved by the grid, the added salt at the sea surface will sink to the base of the mixed layer and then spread horizontally. When averaged at a climate-model grid size, this vertical distribution of …

Uncertainties In Arctic Precipitation, Ipshita Majhi, Vladimir Alexeev, Jessica Cherry, Pavel Groisman, Judah Cohen

Research Posters

It is crucial to measure precipitation accurately to predict future water budget with confidence. In our study, we aim to understand and compare precipitation datasets and discrepancies associated with them. We divide our datasets into three classes-raw data (data that have only been preprocessed to minimum quality control);corrected products (data that have been adjusted by their respective authors); finally, a reanalysis dataset (a combination of observed data and model output).

Propagation Of Tsunami-Induced Acoustic-Gravity Waves In The Atmosphere, Vladimir A. Alexeev, Dmitry J. Nicolsky

Research Posters

A dynamical core of an atmospheric GCM is utilized for assessing the qualitative picture of propagation of atmospheric acoustic-gravity waves in response to perturbations generated by tsunami waves at the surface. Both resting isothermal atmosphere and model- generated atmosphere with realistic stratification and circulation features were considered. Shallow water tsunami model was run in two different configurations: ocean of equal depth of 4 km and ocean with realistic continents and bottom topography. Amplitude and timing of atmospheric response is analyzed as a function of vertical stratification and configuration of atmospheric jets. This approach has a potential for early tsunami detection …

Evaluation Of Prey Composition And Nutritional Value Of Diets Of Free-Ranging Harbor Seals (Phoca Vitulina) From Tugidak Island, Gretchen L. Geiger

Marine Biology

Changes in climate can cause shifts in ecosystem structure that can affect quantity or quality of prey available to predator populations. Due to sex or age-specific behaviors of predators, certain classes within a population may be more severely impacted by changes in their diet. This study evaluated prey composition and nutritional value of summer diets of harbor seals (Phoca vitulina richardii) from Tugidak Island, Alaska from 2001-2009. The MIXIT-WIN program was used to estimate the nutritional value of average harbor seal diets. Changes in relative abundance of certain prey species were correlated to sea surface temperature anomalies. Despite changes in …

Kelp Forests And Barren Grounds: Phlorotannin Production And Holdfast Community Structure In The Aleutian Dragon Kelp, Eualaria Fistulosa, Martin D. Schuster

Marine Biology

The canopy forming kelp Eualaria fistulosa inhabits two organizational states throughout the Aleutian archipelago, kelp forests and barren grounds. Urchin abundance and behavior determines which state dominates in any given area. Sporophyll phlorotannin content and holdfast epibiont fauna were investigated at multiple islands along the Aleutian archipelago to determine how the organizational state affects the production of secondary metabolites and the taxon richness, abundance and biomass of holdfast communities. Barren ground sporophylls had higher phlorotannin content than kelp forest sporophylls, although grazing rates on sporophylls from each state did not differ during in situ grazing experiments. The taxon richness, abundance …

Multiple Regulatory Mechanisms Control B-1 B Cell Activation, Vishal Sindhava, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

B-1 cells constitute a unique subset of B cells identified in several species including mice and humans. B-1 cells are further subdivided into B-1a and B-1b subsets as the former but not the later express CD5.The B-1a subset contributes to innate type of immune responses while the B-1b B cell subset contributes to adaptive responses. B-1 cell responses to B cell receptor (BCR) as well as Toll-like receptor (TLR) ligation are tightly regulated due to the cross-reactivity of antigen specific receptors on B-1 cells to self-antigens. B-1 cells are elevated in several autoimmune diseases. CD5 plays a major role in …

Bereavement In Emerging Adulthood: The Influence Of Religion And Type Of Loss, Elizabeth Collison

Theses and Dissertations

Bereavement is an important area of research as it may result in grief reactions that lead to serious psychological and health consequences (Stroebe, Schut, & Stroebe, 2007). Positive outcomes, such as personal growth or spiritual well-being, may also transpire post-loss (Hogan & Schmidt, 2002; Paloutzian & Ellison, 1982). Though research on bereavement has grown, few studies have focused on the at-risk group of emerging adults (Hardison, Neimeyer, & Lichstein, 2005; Arnett, 2000). The current study aims to add to the bereavement in emerging adulthood literature through analyzing descriptive data and assessing the impact of type of loss (i.e., nonviolent vs. …

Meg Coherence Imaging In Dyslexia: Activation Of Working Memory Pathways, Alfred Mansour

Master's Theses and Doctoral Dissertations

The aims of this dissertation are to 1) review the genetic, neurodevelopmental, structural, and functional brain imaging studies that are the foundations of our understanding of dyslexia and 2) investigate the pattern of activation and functional connectivity of neuronal networks critical in working memory in dyslexics by means of magnetoenchephalographic (MEG) coherence imaging. Dyslexics showed an early onset of activation in the precentral gyrus and the superior frontal gyrus, which differed from controls where activation was initiated in posterior cortical regions (supramarginal gyrus and superior temporal gyrus). Further, dyslexics showed lower normalized amplitudes of activation in the right superior temporal …

Gene, Pathway And Network Frameworks To Identify Epistatic Interactions Of Single Nucleotide Polymorphisms Derived From Gwas Data, Yu Liu, Sean Maxwell, Tao Feng, Xiaofeng Zhu, Robert C. Elston, Mehmet Koyutürk, Mark R. Chance

Faculty Scholarship

Background: Interactions among genomic loci (also known as epistasis) have been suggested as one of the potential sources of missing heritability in single locus analysis of genome-wide association studies (GWAS). The computational burden of searching for interactions is compounded by the extremely low threshold for identifying significant p-values due to multiple hypothesis testing corrections. Utilizing prior biological knowledge to restrict the set of candidate SNP pairs to be tested can alleviate this problem, but systematic studies that investigate the relative merits of integrating different biological frameworks and GWAS data have not been conducted.Results: We developed four biologically based frameworks to …

Closing The Church University In 1894: Embracing Or Accommodating Secularized Education, Brian William Ricks

Theses and Dissertations

The late 1800s have been noted as a major transitional period for the Church of Jesus Christ of Latter-day Saints. When the beleaguered pioneers first arrived in Utah they were isolated from the influence and expectations of the United States. During that time, leaders of the Church became influential in every aspect of life in Utah. By the end of the nineteenth century, however, the period of isolation had come to an end. Nationally, the social norms had changed and religion was expected to stay in the churches and out of politics. Church leaders were faced with serious questions regarding …

Vegf And Angiopoietin-1 Exert Opposing Effects On Cell Junctions By Regulating The Rho Gef Syx, Siu P. Ngok, Rory Geyer, Miaoliang Liu, Antonis Kourtidis, Sudesh Agrawal, Chuanshen Wu, Himabindu Reddy Seerapu, Laura J. Lewis-Tuffin, Karen L. Moodie, Deborah Huveldt, Ruth Marx, Jay M. Baraban, Peter Storz, Arie Horowitz, Panos Z. Anastasiadis

Dartmouth Scholarship

Vascular endothelial growth factor (VEGF) and Ang1 (Angiopoietin-1) have opposing effects on vascular permeability, but the molecular basis of these effects is not fully known. We report in this paper that VEGF and Ang1 regulate endothelial cell (EC) junctions by determining the localization of the RhoA-specific guanine nucleotide exchange factor Syx. Syx was recruited to junctions by members of the Crumbs polarity complex and promoted junction integrity by activating Diaphanous. VEGF caused translocation of Syx from cell junctions, promoting junction disassembly, whereas Ang1 maintained Syx at the junctions, inducing junction stabilization. The VEGF-induced translocation of Syx from EC junctions was …
