Hillslope evolution in response to lateral base level migration
… is consistent with what I expect based on my preferential sampling of slow-moving gently-sloped heads. Several explanations are given to explain why the expected relationship with drainage area is not observed, and suggestions for future work based on these findings is offered.

Experimental Evaluation of Three Backward Transit Time Distributions (bTTD) for Solute Storage and Release During Hyporheic Exchange
… storage are sampled for outflow: (1) uniform sampling (exponential bTTD), plug-flow sampling (Dirac delta bTTD), and preferential sampling of either young or old water (Gamma bTTD). Using the Method of Moments, these three bTTDs were tested against data from 47 previously published hyporheic …

Archaeomagnetic Directional Studies Of Large Fired Structures In Britain
… Scottish sites has been undertaken by extensive sampling of large, physically stable vitrified exposures. Isothermal remanences and the demagnetisation patterns isolated using alternating magnetic fields and thermal methods, show that vitrification occurred under limited oxidation at temperatures …

Geostatistical design and analysis for estimating local variations in malaria disease burden
… papers, we address the problem of geostatistical sampling design. In the first paper, we consider the problem of sampling design for efficient spatial prediction taking account of uncertain covariance structure, in the context of nonadaptive designs. We propose two classes of designs, namely: …

Fitting Stochastic Epidemic Models to Multiple Data Types
… we consider the dependency of genetic sequence sampling times on the latent prevalence of the infectious disease and propose a preferential sampling phylodynamics model that improves performance of phylodynamic inference. In a series of simulation studies, we show that all our proposed …

Exceptional Preservation and Bias in the Fossil Record
… how a newly proposed potential mechanism, the preferential sampling of larger specimens during fossil sampling due to the greater likelihood of larger specimens being intersected by a fracture surface, contributes to the lithification bias. Chapters two and three focus on the exceptionally …

Improved integration of information to reduce subsurface model bias
… with data-related issues like cognitive and sampling biases, and model-related challenges including statistical assumptions, misspecification, and algorithmic biases. These challenges introduce four critical implications during subsurface modeling. Firstly, subsurface sampling is subject to …

A Simulation Approach to Thermodynamics in Interfacial Phenomena
… systems are performed by coupling preferential sampling techniques with connectivity-altering Monte Carlo algorithms to address the challenges in modeling polymer melts in proximity to a solid. The results reveal that polymer architecture holds a prominent role in systems with …
