Meltwater Sources And Sinks For Multiyear Arctic Sea Ice In Summer, Don Perovich, Madison Smith, Bonnie Light, Melinda Webster

Dartmouth Scholarship

On Arctic sea ice, the melt of snow and sea ice generate a summertime flux of fresh water to the upper ocean. The partitioning of this meltwater to storage in melt ponds and deposition in the ocean has consequences for the surface heat budget, the sea ice mass balance, and primary productivity. Synthesizing results from the 1997-1998 SHEBA field experiment, we calculate the sources and sinks of meltwater produced on a multiyear floe during summer melt. The total meltwater input to the system from snowmelt, ice melt, and precipitation from 1 June to 9 August was equivalent to a layer …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Structure-functional studies have recently revealed a spectrum of diverse high-affinity nanobodies with efficient neutralizing capacity against SARS-CoV-2 virus and resilience against mutational escape. In this study, we combine atomistic simulations with the ensemble-based mutational profiling of binding for the SARS-CoV-2 S-RBD complexes with a wide range of nanobodies to identify dynamic and binding affinity fingerprints and characterize the energetic determinants of nanobody-escaping mutations. Using an in silico mutational profiling approach for probing the protein stability and binding, we examine dynamics and energetics of the SARS-CoV-2 complexes with single nanobodies Nb6 and Nb20, VHH E, a pair combination VHH E + …

(Linked) Data Quality Assessment: An Ontological Approach, Aparna Nayak, Bojan Bozic, Luca Longo

Conference papers

The effective functioning of data-intensive applications usually requires that the dataset should be of high quality. The quality depends on the task they will be used for. However, it is possible to identify task-independent data quality dimensions which are solely related to data themselves and can be extracted with the help of rule mining/pattern mining. In order to assess and improve data quality, we propose an ontological approach to report data quality violated triples. Our goal is to provide data stakeholders with a set of methods and techniques to guide them in assessing and improving data quality

Trace Element (Fe, Co, Ni And Cu) Dynamics Across The Salinity Gradient In Arctic And Antarctic Glacier Fjords, Jana Krause, Mark J. Hopwood, Juan Höfer, Stephan Krisch, Eric P. Achterberg, Emilio Alarcón, Dustin Carroll, Humberto E. González, Thomas Juul-Pedersen, Te Liu, Pablo Lodeiro, Lorenz Meire, Minik T. Rosing

Faculty Research, Scholarly, and Creative Activity

Around the Greenlandic and Antarctic coastlines, sediment plumes associated with glaciers are significant sources of lithogenic material to the ocean. These plumes contain elevated concentrations of a range of trace metals, especially in particle bound phases, but it is not clear how these particles affect dissolved (<0.2 µm) metal distributions in the ocean. Here we show, using transects in 8 glacier fjords, trends in the distribution of dissolved iron, cobalt, nickel and copper (dFe, dCo, dNi, dCu). Following rapid dFe loss close to glacier outflows, dFe concentrations in particular showed strong similarities between different fjords. Similar dFe concentrations were also observed between seasons/years when Nuup Kangerlua (SW Greenland) was revisited in spring, mid- and late-summer. Dissolved Cu, dCo and dNi concentrations were more variable and showed different gradients with salinity depending on the fjord, season and year. The lack of consistent trends for dCu and dNi largely reflects less pronounced differences contrasting the concentration of inflowing shelf waters with fresher glacially-modified waters. Particles also made only small contributions to total dissolvable Cu (dCu constituted 83 ± 28% of total dissolvable Cu) and Ni (dNi constituted 86 ± 28% of total dissolvable Ni) within glacier plumes. For comparison, dFe was a lower fraction of total dissolvable Fe; 3.5 ± 4.8%. High concentrations of total dissolvable Fe in some inner-fjord environments, up to 77 µM in Ameralik (SW Greenland), may drive enhanced removal of scavenged type elements, such as Co. Further variability may have been driven by local bedrock mineralogy, which could explain high concentrations of dNi (25–29 nM) and dCo (6–7 nM) in one coastal region of west Greenland (Kangaatsiaq). Our results suggest that dissolved trace element distributions in glacier fjords are influenced by a range of factors including: freshwater concentrations, local geology, drawdown by scavenging and primary production, saline inflow, and sediment dynamics. Considering the lack of apparent seasonality in dFe concentrations, we suggest that fluxes of some trace elements may scale proportionately to fjord overturning rather than directly to freshwater discharge flux.

Effects Of Fiber Clustering On Fatigue Behavior Of Steel Fiber Reinforced Concrete Beams, Danying Gao, Zhiqiang Gu, Congjie Wei, Chenglin Wu, Yuyang Pang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This paper investigated the effects of fiber clustering on fatigue behavior of steel-fiber-reinforced concrete (SFRC) beams with reinforcements by experimental and numerical analysis. The steel fiber volume fractions of beams were 0 vol%, 0.5 vol%, 1.0 vol%, and 1.5 vol%. One beam was tested under static loading, and eight beams under fatigue loading with different stress levels. Moreover, the fiber distribution in the cross section of concrete was experimentally characterized to understand the underlying mechanism. The results indicated that the fatigue life of beam increased with increasing fiber volume fraction from 0 to 1.0 vol% and decreased from 1.0 vol% …

Improved Predictive Modeling Techniques For Non-Linear Solder Material Behavior, Arman Millian Ahari

Dissertations and Theses

Accurate prediction of fatigue life of solder joints in electronic packaging applications becomes of critical importance as semiconductor device technology and manufacturing constraints grow in complexity. To gain visibility on IC device performance and reliability, thermo-mechanical simulation is performed based on a unified, viscoplastic material model, which is dependent on nine parameters.

In this study, an improved method of Anand parameter extraction, which involves curve-fitting non-linear experimental stress data, is proposed to improve the accuracy of numerical predictions for solder reliability. Theoretical equations for uni-axial stress-strain response and creep response are derived, then details on their relevance to experimental and …

Trump's Legacy In The Middle East: Strategic Shift And The Geopolitics Of American Foreign Policy In The Region, Bilel Kriaa

Dissertations and Theses

The last six months of the Trump administration witnessed interesting developments regarding its legacy in the Middle East. The normalization of ties between four Arab states and Israel constituted major breakthroughs not only in the regional inter-state relations but also for the American foreign policy in the region.

In this context, this thesis offers insights into how to understand and evaluate the administration's approach towards these developments. Based on systematic and empirical research, I analyze a corpus comprised of Trump-era foreign policy documents regarding the Iranian and Israeli-Palestinian questions. I find, firstly, that the Trump administration pursued a strategic shift …

On The Scale Dependence Of Foraging In Terrestrial Herbivores, John M. Fryxell, C. B. D. Fortin, J. Wilmshurst

IGC Proceedings (1977-2023)

Meaningful modeling of the spatial and trophic dynamics of terrestrial herbivores demands understanding of the constraints and fitness objectives that presumably underlie behavior. This is complex in terrestrial herbivores, because of scale-dependent constraints on nutrient or energy gain. Mechanistic processes of forage cropping, forage mastication, movements between feeding stations, and forage digestion each have unique constraints that apply on different time, size, and spatial scales. Moreover, competing activities are rarely taken into account. Experimental testing of foraging objectives is therefore clouded by uncertainty regarding which time scale is most relevant from the animal’s perspective, leading to confusion and misrepresentation in …

Understanding sustainable livestock production requires consideration of both qualitative and quantitative factors in a temporal and/or spatial frame. This study adapted Qualitative Comparative Analysis (QCA) to relate conditions of social, economic, and governance factors to changes in livestock inventory across several counties and over time. This paper presents an approach that (1) identified factors with the potential to relate to a change in livestock inventory and (2) analyzed commonalities within these factors related to changes spatially and temporally. This paper illustrates the approach and results when applied to five counties in eastern South Dakota. The specific response variables were periods …

Development Of A New Electro-Osmotic Consolidation Apparatus, Yenni Mariana Ramírez-Mazo, Juan Pablo Osorio, Sergio Agudelo

Conference papers

Electro-osmotic consolidation is a ground improvement technique in which a DC voltage is applied to the soil via electrodes, in order to drain the water contained in the pores increasing the effective stress, and thus improving the geotechnical properties of the soil. The technique increases the shear strength, reduces the compressibility, and changes the chemical composition of the saturated soft clayey and silty soils to which it can be applied. Electro-osmotic consolidation has been successfully applied in different projects worldwide. This paper presents the development of a new electro-osmotic consolidation apparatus built at Universidad de Antioquia. Tests were carried on …

Racial Triangulation, Interest-Convergence, And The Double-Consciousness Of Asian Americans, Vinay Harpalani

Georgia State University Law Review

This Essay integrates Professor Claire Jean Kim’s racial triangulation framework, Professor Derrick Bell’s interest-convergence theory, and W.E.B. Du Bois’s notion of double-consciousness, all to examine the racial positioning of Asian Americans and the dilemmas we face as a result. To do so, this Essay considers the history of Asian immigration to the United States, the model minority and perpetual foreigner stereotypes, Asian Americans’ positioning in the affirmative action debate, COVID-19-related hate and bias incidents, and Andrew Yang’s 2020 Democratic presidential candidacy. The Essay examines how racial stereotypes of Asian Americans have emerged through historical cycles of valorization and ostracism, as …

The Last Call For Civil Rights: Toward Economic Equality, Steve Lee

Georgia State University Law Review

Over six decades have passed since the civil rights movement began in the mid-1950s, but American society has not yet fully realized the promise of the civil rights movement, which at its core embodies the protection and promotion of equity and dignity of all people. Despite the historic improvements that accord the legal protection of equal rights among different races, genders, and ethnic groups, significant economic disparity among racial and regional lines persists. The Reverend Martin Luther King, Jr. declared, “Now our struggle is for genuine equality, which means economic equality.” However, the pursuit of economic equality has not been …

Assessment Of Precise Point Positioning Of Different Global Navigation Satellite Systems., Islam Ashour, Mohamed El-Tokhey, Yasser Mogahed, Ahmed Ragheb

Mansoura Engineering Journal

With the accelerated development of multi constellation Global Navigation Satellite Systems (GNSS), the field of satellite navigation is going through profound changes. Depending on a single constellation may not be sufficient to guarantee a successful positioning accuracy at any time. Consequently, having several constellations that can be used for positioning offers the opportunity to maintain continuous positioning. This became possible with the global coverage of other constellations such as (BeiDou, GLONASS, Galileo, and GPS). For engineering and scientific applications, this will present both opportunities and obstacles. This paper develops a 4-system positioning model for all the available observations from other …

Current Evidence On Potential Of Adipose Derived Stem Cells To Enhance Bone Regeneration And Future Projection, Quang Le, Vedavathi Madhu, Joseph M Hart, Charles R Farber, Eli R Zunder, Abhijit S Dighe, Quanjun Cui

Department of Orthopaedic Surgery Faculty Papers

Injuries to the postnatal skeleton are naturally repaired through successive steps involving specific cell types in a process collectively termed “bone regeneration”. Although complex, bone regeneration occurs through a series of well-orchestrated stages wherein endogenous bone stem cells play a central role. In most situations, bone regeneration is successful; however, there are instances when it fails and creates non-healing injuries or fracture nonunion requiring surgical or therapeutic interventions. Transplantation of adult or mesenchymal stem cells (MSCs) defined by the International Society for Cell and Gene Therapy (ISCT) as CD105+-CD90+CD73+CD45-CD34-CD14orCD11b-CD79αorCD19-HLA-DR-is being investigated as an attractive therapy for bone regeneration throughout the …

Geological Origin As An Input Variable In Reliability-Based Designs: For An Accurate Exploration In Geotechnical Engineering, Juan Camilo Viviescas, Juan Pablo Osorio

Conference papers

Soil is one of the most difficult materials to characterize realistically, which partly explains the uncertainty between the designs and the geostructures real behavior. Different recommendations have arisen with respect to carrying out field investigations in order to reduce the uncertainties inherent to the soil. However, the field exploration and the implementation of sophisticated geotechnical models have proven to be insufficient to mitigate the geotechnical uncertainty. Therefore, Reliability-Based Designs (RBD) emerge as a decision-making tool through the definition of the probability of failure in conjunction with the typical Factors of Safety. RBD requires a previous understanding of the most appropriate …
