CD antigens. Immune response -- Regulation. Hemoglobin.
CD163 is a monocyte- and macrophage-specific surface glycoprotein proposed to function in the maintenance of homeostasis and the resolution of inflammation. CD163 binds hemoglobin-haptoglobin complexes implicating this receptor as a hemoglobin...
We examine variations of cops and robbers games on graphs. Our goals are to introduce some randomness into their study, and to estimate (expected) capture time. We show that a cop chasing a random walker can capture him in expected time n + o(n)....
Angiogenesis is part of the natural defense mechanism in brain against hypoxia and ischemia. Animal models and methods for the non-invasive investigation of cerebral angiogenesis are needed. This thesis addresses the hypothesis that steady state,...

A polynomial is a product of distinct cyclotomic polynomials if and only if it is a divisor over [Special characters omitted.] [x ] of xn - 1 for some positive integer n. In this thesis, we will examine two natural questions concerning the divisors...
Eddy currents (Electric) -- Mathematical models. Electric generators -- Windings. Finite element method.
Magnetic components, such as transformers and inductors, are essential parts of most power electronics circuits. They usually are the largest components in the circuit, and also account for a large portion of the power loss. Reducing the volume of...
The study of twin primes gives rise to several famously difficult problems in number theory--in fact, we still cannot definitively say whether there are infinitely many twin primes. In this work, we consider a related problem, namely: What is the...

The Î²-hemoglobinopathies sickle cell disease and Î²-thalassemia represent some of the most common inherited diseases. It is recognized that increased fetal hemoglobin (HbF) ameliorates symptoms, mortality and morbidity in Î²-hemoglobinopathy...
Naturally occurring macrocyclic tetrapyrroles of the chlorin and bacteriochlorin classes play important roles in essential biological processes, including photosynthesis and nitrogen cycling. The chromophores also show promise in various...
In this thesis, the dynamics of long-lived, time-dependent, coherent field configurations, known as oscillons, are investigated in the presence of an expanding background. In a (1+1)-dimensional expanding spacetime, scalar-field oscillon lifetimes...
This thesis contains material relating to two separate subjects. The first section determines when the C*-algebra affiliated to a directed graph has continuous trace. We use groupoid methods and the focus is on producing conditions on a graph that...
Fluorine forms the strongest single bond to carbon, however, it is well established that transition metals can lengthen and weaken C-F bonds in fluorinated ligands. Described here are studies on the activation of C-F bonds in iridium compounds...
We present a number of findings concerning groupoid dynamical systems and groupoid crossed products. The primary result is an identification of the spectrum of the groupoid crossed product when the groupoid has continuously varying abelian...

One of the principle aims of ecology is to understand variations in organism abundance over time. Some species and species assemblages exhibit exceptionally dynamic changes in abundance or biomass, while other species and species assemblages are...
Renewable energy sources are becoming increasingly important as sustainable alternatives to fossil fuels. One of these renewable sources, cellulosic biomass, is a relatively inexpensive and abundant resource that can be converted into liquid fuels...
The focus of this thesis is the study of nuclearity and exactness for groupoid crossed product C*-algebras. In particular, we present generalizations of two well-known facts from group dynamical systems and crossed products to the groupoid setting....
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...
Increased fetal hemoglobin (HbF) expression is beneficial for [beta]-hemoglobinopathy patients; however, most inducing agents do not possess the ideal combination of efficacy, safety and availability. Better understanding the mechanisms involved in...
Microwave imaging (MI) is based on recovering dielectric properties (permittivity and conductivity) of materials. Over the last two decades, MI has attracted increasing interests in biomedical applications, in particular, for breast cancer...
Epilepsy is the most common neurological disorder in children, with an incidence of 100 per 100,000 children per year. Recurrent seizures during this period in life are often distressing to the individual and the family, but arguably the most...
Earlier in our laboratory, a facile synthesis of the 2- and 3-nitroindoles was realized. These compounds showed promise as powerful intermediates in the synthesis of novel structures and natural products. The reactivity of 2- and 3-nitroindoles...
Ionospheric radio wave propagation -- Observations. Hiss (Radio meteorology). Auroras -- Antarctica -- Observations.
A VersatIle Electromagnetic Waveform (VIEW) receiver was deployed at South Pole station in December 2002 in order to measure the fine structure of auroral radio emissions with high resolution and an unprecedented 500-1000 kHz bandwidth. Using this...
Zinc -- Physiological transport. Arabidopsis thaliana -- Physiology. Homeostasis. Trace elements in plant nutrition.
Zinc deficiency is a widespread and common problem in many organisms. In plants, zinc deficiency causes growth inhibition, resulting in reduced final yields. Although zinc is an essential element in plants, zinc uptake, translocation and...
Diagnostic imaging -- Mathematics. Expectation-maximization algorithms. Imaging systems in medicine -- Mathematics.
We have developed a general-purpose registration algorithm for medical images and volumes. The transformation between images is modeled as locally affine but globally smooth, and explicitly accounts for local and global variations in image...
