Non-inertial Undulatory Locomotion Across Scales
Locomotion is crucial to behaviors such as predator avoidance, foraging, and mating. In particular, undulatory locomotion is one of the most common forms of locomotion. From microscopic flagellates to swimming fish and slithering snakes, this form of locomotion is a remarkably robust …

Population processes and patterns across scales
… by a multitude of processes operating at various scales. Two approaches are especially powerful at linking these processes to patterns: mathematical modeling and using a citizen science dataset. This dissertation uses these two approaches to detect unobservable biological processes from observable …

Time Scales, Coherency, and Weak Coupling
In this thesis we study a relation between time scales and structural properties of a class of systems represented by power systems. First, the time scale decomposition of linear time invariant systems is studied. The properties of the time scale decomposition are shown to be defined by properties …

Modeling cross scales in polymer upcycling
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-03-01 without embargo terms

Robust structured multigrid at extreme scales
The solution of elliptic partial differential equations is a common performance bottleneck in scientific simulations. By exploiting structure in a problem, robust structured multigrid methods gain important performance benefits because they preserve structure throughout the multigrid hierarchy. In …

Modeling cellular metabolism in multiple scales
… within relevant biological time and length scales. Despite recent advances QM calculations, the computational cost of studying nanosecond-long dynamics of entire systems relying solely on QM methodologies is prohibitive. To circumvent this cost barrier, it is possible to confine the QM …

Learning to Model Atoms Across Scales
… enough, limiting the applicable domains and scales. Furthermore, discovering new materials and drugs requires novel candidate atomistic structures, which are conventionally based on heuristic or exhaustive search methods. This thesis presents machine learning methods for modeling atoms for …

Coupled length scales in eroding landscapes
… drainage basins, characteristic coupling length scales are found which indicate an important breaking of scale invariance. We also show that these length scales are related to the average sizes of the individual drainage basins. Our study demonstrates one way in which landscape patterns of …

Exploring QCD Factorization at Moderate Energy Scales
… processes are sensitive to a wide range of scales. Thus, it is necessary in QCD calculations to utilize a factorization scheme to separate a process into perturbative and non-perturbative factors. This separation relies on an assumption that one energy scale is infinitely larger than the …

Biomass burning emissions on regional-global scales
Biomass burning (BB) is the second largest source of trace gases and the largest source of primary fine carbonaceous particles in the global troposphere. Many recent BB studies have provided new emission factor (EF) measurements for non-methane organic compounds (NMOC), which are highly reactive …

CP-Violation and Baryogenesis on Electroweak Scales
… different aspects of CP-violation on electroweak scales and in this context quantum transport in electroweak baryogenesis. First we focus on CP-violation of CKM type as it is present in the Standard Model. We explain basic concepts and the reason for the smallness of CP-violation in direct …

Coral adaptations across ecological and evolutionary scales
… gradients) and small (e.g., different depths) scales. Populations that exist across these environments might be adapted to local conditions and exhibit genetic divergence between habitats, sometimes to the point of becoming different species or lineages within a species complex. Corals are …
