Tidal signatures in gravitational waves and systematic biases due to waveform inaccuracies
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2026-12-01

Social information processing in aggressive and withdrawn preschool children
… in children. Within the framework of that model, systematic biases have been found in the manner in which aggressive children process social information. The present study sought to extend that literature by applying the model to younger children, by examining the processing of withdrawn, as well …

Building Inventory Simulations for High Velocity Garment Retail Stores
… were able to model store inventory with little systematic biases and store daily mean absolute inventory deviations within 2-4%. Meanwhile for the machine learning models, the project systematically examined the efficacy of linear regression, tree and fully connected neural network models at …

Enhancing the Reliability of Real-World Evidence and Clinical Decision-Making: Robust, Calibrated, and Uncertainty-Aware Methods for Observational Healthcare Research
… challenges, such as model misspecification, systematic biases, and uncertainties in predictions, potentially compromising the reliability and validity of generated evidence. Ensuring reliability is particularly vital for real-world decision-making, where trustworthy evidence must explicitly …

Causality and self-signaling in economic games
… games with no information flow and we show systematic biases in estimates of what one's partners have done versus the population. Both of these phenomena are consistent with a combination of self-signaling and a limit on the direction of inference in time.

Analysis and interpretation of high-throughput chemical-genetic interaction screens.
… interaction scores and provides tools to remove systematic biases and other unwanted signals from large-scale datasets. The latter provides for interpretation of chemical-genetic interaction profiles via a compendium of reference genetic interaction profiles, with a focus on controlling the false …

Does Temperament Differentially Influence Study Completion Rates for 18 and 24-Month-Olds Participating in a Remote Study?
… variability in participation. That is, are there systematic biases in final samples due to differences in participant characteristics, such as temperament? Particularly for remote work, the increased variability has created challenges for researchers to collect data but also exciting opportunities …

Marine snow tracking stereo imaging system
… complexity of this Pump, however, together with systematic biases in available measurement methodologies and vast spatial and temporal undersampling, makes this quantification difficult. In this thesis I set out to design and build a low-cost underwater stereo-imaging system to remotely measure …

A constraint optimization framework for discovery of cellular signaling and regulatory networks
… can be exposed in one experiment because of systematic biases in the assays. These unexpected and hidden components of the cellular response are often the most interesting, because they can provide new insights into biological processes and potentially reveal new therapeutic approaches. …

Stochastic Approaches to Coupled Cluster Theory
… local physical systems. The presence of various systematic biases resulting from wavefunction nonlinearity within these approaches is then investigated. All metrics introduced are found to be negligible compared to the accuracy required for chemical applications in an example system, and possible …

Language Comprehension, Production, and Reasoning in Humans and Neural Language Models
… Finally, Study 4 compares human and LM reasoning systematically—LMs achieve higher syllogistic reasoning accuracy than humans while still replicating several fine-grained human-like error patterns that are orthogonal to logical accuracy, including premise ordering effects. These converging …

GIS methods for screening potential environmental justice areas in New England
… amounts of hazardous pollution as a result of systematic biases in policy making and discriminatory market forces. Geographic Information Systems (GIS) is an important tool used to assist regulatory agencies in identifying these potentially vulnerable or "potential environmental justice" areas …

Constraining the Major Merging History of Massive Galaxies: A Comprehensive Analysis of Close Pairs and Tidal Features Using Empirical and Simulated Data
… of five owing to their unique but analogous systematic biases, especially during the key epoch of galaxy growth (7-11 Gyr ago), highlighting that the merger contribution to galaxy growth remains poorly constrained. As a step towards addressing key open questions pertaining to empirical merger …

Ensemble-characterisation of satellite rainfall uncertainty and its impacts on the hydrological modelling of a sparsely gauged basin in Western Africa
… variations in rainfall resulting in large systematic biases. These biases were observed propagating directly to the modelled hydrological ouput.

AN OBSERVATIONAL STUDY OF LOW-MASS STAR FORMATION IN NGC 2264
… 2264 stars in the H-R diagram are examined. No systematic biases in the derived bolometric luminosities and temperatures are found. The optical and infrared excesses of these stars are found to be uncorrelated, requiring separate mechanisms for their generation. A gaseous envelope is most likely …

The Influence of Physical Processes in Galaxy Clusters on Observable Cluster Scaling Relations
… (SZ) scaling relations. We also examine possible systematic biases in cluster cosmology, such as sample selection in cluster surveys, assumptions in self-calibration studies, and correlated errors in combining X-ray and SZ mass estimates. Correctly simulating cluster properties, especially inside …

Representation Learning for Patients in the Intensive Care Unit
… that they are periodic signals with particular systematic biases) to improve upon the state-of-the-art in length of stay prediction (with additional investigations into mortality prediction). In Chapter 4, I am again inspired by knowledge of the clinical decision making process to propose a …

Fundamental aerosol-cloud interactions and their influence on the aerosol indirect effect on climate
… single-mode aerosol populations, but show systematic biases in high-pollution, weak-updraft regimes. These are exacerbated when the aerosol in question is a complex mixture. We show that estimates of droplet nucleation are highly sensitive to changes in the accumulation mode size and number …

Exceptional Preservation and Bias in the Fossil Record
… fossil assemblages and the existence of systematic bias in the fossil record from a variety of sources represent opposing forces acting on the information quality of the fossil record. Exceptionally preserved assemblages capture features of anatomy and components of assemblages not …

Evaluations and Consequences of Tumour Evolution
… subclonal reconstruction algorithms and reveal systematic biases introduced by SNV and CNA detection tool choice. I also quantify the extent that single-region subclonal reconstruction underestimates intra-tumour heterogeneity as compared to multi-region reconstruction. Taken together, these …
