Methods for Accurately Modeling Complex Materials
… model nanomagnetic systems, and novel empirical potentials that reproduce ab-initio data at a fraction of the computational cost. We also present a new global optimization procedure that we have implemented for computationally demanding classical potential fits.

Global Existence of solutions to Reaction-Diffusion Systems with Mass Transport type Boundary Conditions
… then there exists solution for all time, t>0. Classical potential theory and estimates for linear initial boundary value problems are used to prove local well-posedness and global existence. This type of system arises in mathematical models for cell processes.

The gravity of modern amplitudes: using on-shell scattering amplitudes to probe gravity
… Relativity. The second is the ability to derive classical results from the amplitudes. In this section we use on-shell scattering amplitudes to derive the perturbative metric of a rotating black hole in a generic form of Einstein gravity that has additional terms cubic in the Riemann tensor. We …

Brownian motion and multidimensional decision making
… body, references and page numbering. Part I, "Potential theory, path integrals and the Laplacian of the indicator", finds the transition density of absorbed or reflected Brownian motion in a d-dimensional domain as a Feynman-Kac functional involving the Laplacian of the indicator, thereby …

Machine learning approaches to challenging problems : interpretable imbalanced classification, interpretable density estimation, and causal inference
… estimate personalized treatment effects in the classical potential outcomes framework with binary outcomes. Strictly, both treatment and control outcomes must be measured for each unit in order to perform supervised learning. However, in practice, only one outcome can be observed per unit. To …

Exciton behaviour at organic solar cell interfaces
… materials. In particular, we use mixed quantum/classical dynamical simulations and electronic structure calculations to investigate several oligomer-fullerene systems. In order to study the potential energy surfaces guiding the dynamics of electron transfer, the nuclear and electron dynamics of …

A combined experimental and theoretical approach towards the understanding of transport in one-dimensional molecular nanostructures
… temperatures is observed. Within the semi-classical potential adopted, the critical strain values of structure rupture lie in the same range of their pristine SWCNT counterparts. This is directly verified by the first observations of these ring-like structures in a transmission electron …

Topics in conditional causal inference
… five chapters. In Chapter 1, we first review the classical potential outcomes framework and some basic causal inference methods relevant to this thesis, then provide a summary of the problems and methods studied in the following chapters. In Chapter 2, we consider testing causal effects in complex …
