Magnetic resonance imaging. ; Nuclear magnetic resonance.
Diffusion-weighted magnetic resonance imaging (MRI) provides unique contrast reflecting the translational motion of water in its microscopic environment. This imaging modality has been shown to highlight infarcted regions within minutes after an...
An interval order is an ordered set whose elements are in correspondence with a collection of intervals in a linearly ordered set, with disjoint intervals ordered by their relative position. The order complex of an ordered set is the simplicial...
Î±-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) function as paracrine and autocrine receptors throughout the body. Most studies have focused on their role in fast excitatory neuronal signaling, and learning and memory. In...
Geology -- Guatemala -- Lake Atitlan area; Volcanism -- Guatemala -- Lake Atitlan area; Calderas -- Guatemala -- Lake Atitlan area.
Geological mapping, petrological and geophysical studies in the lake Atitlan area, Guatemala, have revealed four distinct periods of stratovolcano growth, each followed by major silicic eruptions and caldera collapse. The first period (12 - 11 my...
This thesis focuses on the emergence of universal dynamical scaling in quantum critical spin systems driven out of equilibrium, with emphasis on quench dynamics which involves isolated standard critical points, multi-critical points, and...
The first chapter of this thesis encompasses progress towards the X-ray structure determination and drug design for the dihydrofolate reductase-thymidylate synthase (DHFR-TS) enzyme from the protozoa Toxoplasma gondii, along with another mutant...
This thesis constitutes the first steps in the author's program to investigate the question of when a homotopy of 2-cocycles Ï‰ = {Ï‰[subscript t]}[subscript tâˆŠ[0,1]] on a locally compact Hausdorff groupoid Æ“ induces an isomorphism of the...
Si/SiGe quantum dots (QDs) are promising candidates for spin-based quantum bits (qubits) as a result of the reduced spin-orbit coupling as well as the Si isotopes with zero nuclear spin. Meanwhile qubit readout is a challenge related to...
In this thesis, we consider several problems relating to cyclic subgroups of the group [mathematical equation]. Each element of [mathematical equation] has a unique representative in one of the two intervals [mathematical equation] and...
Manifolds (Mathematics) Geodesics (Mathematics) Space and time.
We investigate weak and strong refocusing of light rays in a space-time and related concepts. A strongly causal space-time ( X^ n +1 , g ) is emphstrongly refocusing at x âˆˆ X if there is a point y â‰ x such that all null-geodesics through y pass...
Electric generators -- Windings. Electric inductors -- Design and construction -- Mathematical models. Electric current converters -- Design and construction -- Mathematical models. Energy dissipation -- Mathematical models.
Magnetic components for high-frequency power conversion applications can have significant losses that compromise the performance of the converter. In particular, winding losses can be large due to high-frequency effects that are difficult to model...
This thesis investigates the embedding theory of orders in central simple algebras, placing a particular emphasis on the role that the phenomenon known as selectivity plays in the theory. Although the notion of selectivity is completely algebraic,...
Acyl-CoA:Cholesterol Acyltransferases (ACATs) are key enzymes in cellular cholesterol metabolism. ACAT converts free cholesterol to cholesterol ester, which makes it more easily storable in lipid droplets. There are two ACAT genes encoding two...
Genome sequencing technology has enabled the identification of genetic variants that are linked with cancer phenotypes, whether these are somatically acquired mutations or common inherited single nucleotide polymorphisms (SNPs). Whereas coding...
Despite the array of targeted therapeutics that currently exist to combat breast cancer, disease progression leading to metastasis, and tumor recurrence still remains a significant clinical challenge. Efforts to identify novel pathways and...
