Geometric and algebraic properties of polyomino tilings
… In particular, we focus on two main themes: local connectivity and tile invariants. Given a set of tiles T and a finite set L of local replacement moves, we say that a region [Delta] has local connectivity with respect to T and L if it is possible to convert any tiling of [Delta] into any …

Models and algorithms of brain connectivity, spatial sparsity, and temporal dynamics for the MEG/EEG inverse problem
… means to study fast neural dynamics in humans. Localizing the sources of brain activity from MEG/EEG is an ill-posed inverse problem, with no unique solution in the absence of additional information. In this dissertation I analyze how solutions to the MEG/EEG inverse problem can be improved by …

Towards a Modular Superconducting Quantum Processor using Chiral Waveguide Quantum Electrodynamics
… and computational schemes that exploit non-local connectivity to enhance processing capabilities. This work proposes non-local entanglement generation methods based on the theory of chiral quantum waveguide dynamics, which is the quantum-optical framework that describes systems of atoms …

Temporal information partitioning networks to infer ecohydrologic behaviors
… behavior of individual components and the connectivity between them determines the dynamics. This connectivity between components can act to constrain, accentuate, or otherwise modify the variability of individuals. In an ecohydrologic system, connectivity exists in the form of many time …

Toroidal Matrix Links: Local Matrix Homotopies and Soft Tori
In this document we solve some local connectivity problems in matrix representations of the form C(T^N) -> M_n and C(T^N) -> M_n <- C([-1, 1]^N) using the so called toroidal matrix links, which can be interpreted as normal contractive matrix analogies of free homotopies in algebraic topology. In …

The structure of 4-separations in 4-connected matroids
… called a k-flower, with no assumptions on the connectivity of M. We completely classify k-flowers in terms of the local connectivity between pairs of petals. Specializing to the case of 4-connected matroids, we give a new notion of equivalence of 4-separations that we show will be needed to …

Bridging adaptive estimation and control with modern machine learning : a quorum sensing inspired algorithm for dynamic clustering
… their functional behaviors based only on local decision and cell-medium interaction. This thesis draws inspiration from quorum sensing to study the data clustering problem, in both the time-invariant and the time-varying cases. Borrowing ideas from both adaptive estimation and control, and …

Influence of the structure of the orientation preference map on the responses of V1 neurons
… visual cortex (V1) neurons arise from the dense local projections of neighboring neurons. Although several proposals have been made, it is not known what role these connections play in shaping the response properties of V1 neurons. It was reasoned that the influence of local inputs on orientation …

Tidally Induced Transport Dynamics in a Wadden Sea Tidal Basin and Its Changes Under Future Sea Level Rise Scenarios
… create spatial structures of hydrodynamic connectivity that govern transport processes, ecological functioning, and the interpretation of long-term observations. However, the persistence of these structures under future sea level rise and changing wind conditions remains uncertain. This …

On Hardware Implementation of Discrete-Time Cellular Neural Networks
… Simplicity of operation together with the local connectivity gives CNNs first-hand advantages for tiled VLSI implementations with very high speed and complexity. The first VLSI implementation has been based on analogue technology but was small and suffered from parasitic capacitances and …

Interference channels with coordinated multi-point transmission
… > 1 for any message assignment that satisfies a local cooperation constraint. On the other hand, when the assumption of full connectivity is relaxed to local connectivity, and each transmitter is connected only to its own receiver as well as L neighboring receivers, it is shown that local …

Passive biomimetic actuators : the role of material architecture
… material expands is variable and depends on the local cell’s connectivity. This has repercussions both at the macroscopic (lattice level) and microscopic (cells level) scales. At the macroscopic scale, these non-convex lattices can experience large anisotropic (similarly to the diamond shaped …
