Minimal Models and Riemannian Foliations
In this work, we consider minimal models of Riemannian foliations on connected, simply-connected manifolds following Lehmann. We show that if the minimal model has an underlying rational form of finite type, then it can be realized in rational homotopy by a fibration of finite CW complexes. As a …

Physical minimal models of amoeboid cell motility
… collective behavior. In this thesis, we utilize minimal modeling to investigate single and collective cell motility in three different settings. The key question we strive to answer is whether cell locomotion is a physical process that can function without the biochemistry that controls it. …

Redesigning specificity in miniproteins
… miniprotein interactions using computational models and then testing these designs with experiments. Miniproteins are small, autonomously-folding proteins that are excellent for testing protein designs because they can be chemically synthesized and computationally modeled. Despite their …

Gröbner bases in rational homotopy theory
… avoid the use of differential graded algebra and minimal models, and instead approach simple but open problems in rational homotopy theory using a simplicial perspective and the combinatorial properties of Gröbner-Shirshov bases.

Homotopy theory of moduli spaces
… application constructs certain moduli spaces as models for unbased disconnected rational topological spaces. The second application constructs certain moduli spaces as those governing formal algebraic deformation problems over, not necessarily local, commutative differential graded algebras. The …

Entanglement entropy in integrable quantum systems
… using integrable tools in continuum and discrete models. In particular, in the first article we generalise the method described in the seventh article in order to take into account non unitary conformal systems. In the second article we use a form factor expansion to probe a non unitary system …

Measuring and Modeling The Response Characteristics Of The Environmental Phosphate Transducer In Escherichia Coli
… part of this study, we investigate a series of minimal models, simple extensions of the birth-death process, that have response characteristics in common with the measured transducer response. We find that using the Hill equation as the functional form of the birth rate in an autoregulating …

The design and structural characterization of oligomeric beta beta alpha mini-proteins
… with protein-like features, constitute valuable minimal models for the study of oligomeric proteins. Oligomerization is a common feature of cellular proteins that may confer structural and functional advantages. Oligomerization is proposed to have arisen by several evolutionary pathways. The …

An Algebraic Approach to Reverse Engineering with an Application to Biochemical Networks
… perturbations. The construction of mathematical models based on observation of these responses, referred to as reverse engineering, is an important step in elucidating the structure and dynamics of such networks. Continuous models, described by systems of differential equations, have been used to …

Minimalist Models and Methods for Visibility-Based Tasks
This dissertation proposes minimal models for solving visibility-based robotic tasks. It introduces strategies that handle sensing and actuation uncertainty while avoiding precise state estimations. This is done by analyzing the space of sensing and actuation histories, the history information …

Chromatin-based memory of prolonged cold exposure in Arabidopsis thaliana
… in the chromatin of the FLC gene. Mathematical models developed in this work focus on understanding how chromatin states are maintained and also re-established after DNA replication. Minimal models are used to investigate if a particular set of interactions between chromatin and …

Complex Fluid Dynamics: From Laminar to Geophysical Flows
… environments. We also present highly successful minimal models which explain the formation of depositional facies and large scale travertine motifs, including the characteristic terrace architecture found at carbonate hot springs. Our numerical model predicts dynamical phenomena which are seen at …

Phase transitions in fluids and biological systems
… states. I consider generic and statistical models for transitions between these global states, and I relate the model results with experimental data. A theme of this thesis is that these rather simple, minimal models are able to capture a lot of functional detail about complex dynamical …

Conformal Boundaries, SPTs, and the Monopole-Fermion Problem
… the recently-introduced family of fermionic minimal models, which are derived by fermionising the more familiar bosonic minimal models. We construct the boundary states for these models, and explain how our results and their interpretation in terms of 2d SPTs carry over from the Dirac fermion …

Uncovering Biophysical Determinants Of Oxidoreductase Function Through De Novo Protein Design

QUANTUM SIMULATION OF BOSONIC SYSTEM AND APPLICATION OF MACHINE LEARNING
… (CFTs). We first use the energy spectra of these minimal models to train a supervised learning algorithm. In contrast to conventional methods that are typically qualitative and involve system size scaling, our method quantifies the similarity of the spectrum of a system at a fixed size to …
