Optimism and Robustness: Learning From Structured and Semi-Random Inputs
… to contamination in average-case inputs (semi-random inputs). In the context of low-rank matrix recovery problems, this means a monotone adversary can add arbitrary data from the distribution to break the necessary regularity conditions satisfied by fully random inputs. In Chapter 4, we …

January: Search Based On Social Insect Behavior
… (NOW). The agent's search pattern is a semi-random walk based on the behavior of the grey field slug (Agriolimax reticulatus), the house fly (Musca domestica), and the black ant (Lassius niger). The agents communicate to lessen the amount of duplicate work being done. Every algorithm has …

Lithium pellet injection into high pressure magnetically confined plasmas
… the filaments in L-mode plasmas appeared to be semi-random, with the direction changing randomly from shot to shot, but with a distinct preferred direction during each shot. The susceptibility of the filament's motion to variations in the background plasma conditions indicate that the drift is a …

Detection power, temporal response, and spatial resolution of IRON fMRI in awake, behaving monkeys at 3 Tesla
… BOLD and IRON contrasts could be optimized using random or semi-random distributions for interstimulus intervals. Small increases in predictability could be traded for large gains in efficiency, particularly for the IRON method. A general linear model was successfully employed to describe IRON and …

In Vitro Evolution of Antibody Affinity using Libraries with Insertions and Deletions
… aim of this thesis was to study the impact of random and high diversity indels on antibody affinity by in vitro evolution. New approaches for construction of libraries with in-frame amino acid indels were applied to enable sampling of indels of different lengths across the entire antibody …

Insights into the clonal inventory of gene corrected human SCID-XI hematopoiesis
The semi-random nature of retroviral integration introduces a stable molecular marker into the cellular genome in the form of a genomic-proviral fusion sequence which can be passed on unmodified to all the progenies of a transduced cell. Retroviral integration site analysis provides a powerful …

Lead and Copper Contamination in Potable Water: Impacts of Redox Gradients, Water Age, Water Main Pipe Materials and Temperature
… in lead and copper during sampling due to semi-random detachment of lead particles to water, which can pose an acute health concern. Well-controlled test rigs were used to characterize the variability in lead and copper release and compared to consumer sampling during the LCR. The …

Modeling Arsenic, Antimony, And Selenium Partitioning During Coal Combustion
… selenium-are of particular interest due to their semi-volatile nature.</p> <p>Modeling the partitioning of semi-volatile elements-arsenic, antimony, and selenium-is the focus of this undertaking. Programming was done in C++ with particle-time-temperature inputs from computational fluid dynamics …

Making a digital working class : Uber drivers in Boston, 2016-2017
… provides a typology of Uber drivers based on semi-random sampling through ride-alongs. The second chapter describes collective action that was undertaken by Uber drivers at Boston's Logan Airport in the form of a strike against the algorithm, which was an effort to induce the software to …

Stability and Control in Complex Networks of Dynamical Systems
… networks are often modeled to have a completely random (Erdös-Rényi) or semi-random (Small-World) topologies. The former model is often used due to mathematical tractability while the latter has been shown to be a better model for most real life networks. The recent emergence of cyber physical …

Engineering of transcription activator-like effector nucleases (TALENs) for targeted genome editing
… developed to for efficient gene insertion, the random or semi-random integration can disrupt certain endogenous genes and cause unpredictable phenotypes. In contrast, targeted genome editing enables researchers to tailor genomic loci in a specific manner. Applications include studying gene …

Dictionary learning for scalable sparse image representation
… HVS properties is carried out by introducing a semi-random Morphological Component Analysis (MCA) based initialisation of the scalable dictionary and the regularisation of its atom's update mechanism. Subsequently, this enables scalable sparse image reconstruction. In general, dictionary …

Lead (Pb) Contamination of Potable Water: Public Health Impacts, Galvanic Corrosion and Quantification Considerations
… (1 inch wide) that constituted a reservoir for semi-random particulate lead detachment into the water. The work on simulated partial pipe replacements revealed that under worst-case scenarios of highly contaminated water samples, most of the lead was not quantified if water samples were not …
