Thermodynamics, and the classic balance between entropy and enthalpy, provides a proverbial zoo of exotic phase behaviour that chemists can harness to create new materials out of simple liquids and polymers. The diversity of self-assembling...
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...
Understanding trace element homeostasis in plants has a direct impact on global health. Much of the developing world suffers from nutrient deficiencies, and subsists on a plant based diet often lacking bioavailable nutrients like iron and zinc. At...
Large scale systems -- Mathematical models. Digital computer simulation. Parallel processing (Electronic computers). Computer algorithms.
Modeling real-world large-scale systems is inherently challenging due to their size and complexity. Detailed simulation of large-scale models requires tremendous amounts of computing power and memory space. Parallel discrete-event simulation...
Despite great progress in object recognition techniques, there is a mismatch between traditional approaches and the characteristics of real world vision tasks. We highlight in particular, three closely related areas of mismatch: i) recognition...
In this thesis, we characterize and enumerate the permutations which are realized by the orbits of signed shifts, a family of discrete dynamical systems on words. The permutations, which are called patterns of the signed shifts, are given by the...
How is concrete conceptual information represented in the brain? Little is known about the neural organization for details of concrete objects when presented as words. The goal of the first two studies was to investigate this. In the third study,...
Bradyrhizobium japonicum forms a nitrogen-fixing symbiosis with soybean. Signaling events, such as production of flavonoids and Nod factor, initiate the interaction, leading to formation of specialized root organs called nodules. A B. japonicum...
Polynomials. Finite fields (Algebra). Algebraic functions. Number theory.
The ring of univariate polynomials over a finite field shares many foundational arithmetic properties with the ring of rational integers. This similarity makes it possible for many problems in elementary number theory to be translated 'through the...
In this thesis we look at several problems that lie in the intersection between combinatorial and multiplicative number theory. A common theme of many of these problems are estimates for and properties of the smooth numbers, those integers not...
Genetic and immunological tools have been used to study two protozoan parasites, Plasmodium falciparum and Toxoplasma gondii. Toxoplasma gondii provides an excellent model for the study of protozoan parasite biology. Plasmodium falciparum causes...
Electric fields in the high-latitude regions of Earth's ionosphere are an important component of the coupled magnetosphere-ionosphere-thermosphere system. Characterizing the average behavior of these fields (or the corresponding drifts) is useful...
Endothelial cell migration is an important element of a number of biological processes, including angiogenesis. The fibroblast growth factors (FGFs) are a family of angiogenic heparan-binding proteins that potently induce endothelial migration....
Traditionally, mast cells have been studied for their role as proinflammatory effector cells in allergic disorders. Recent findings however have opened up the discussion in the community of immunologists regarding MCs should be considered as...

A pre-requisite for proper health of the cell and the organism is accurate chromosome segregation during cell division. Defects in chromosome segregation lead to aneuploidy, a hallmark of an unstable genome and a frequent attribute of cancer and...
Staphylococcus aureus contains 4 native, membrane-bound penicillin-binding proteins (PBP1-4) which are responsible for critical peptidoglycan transglycosylation and transpeptidation reactions in the cell wall. Additionally, PBP2 and PBP4 also...
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...
As the visual effect and movie industries are striving for realism and high fidelity images, physically based lighting, global illumination, realistic materials, and highly tessellated geometry are gradually accepted and used in movie and game...
Accurate chromosome segregation in human oocytes requires that meiotic sister chromatid cohesion remain intact for decades and work in model organisms indicates that deterioration of meiotic cohesion over time may be a major determinant of...
During our fieldwork with real-world organizations---including those in Public Key Infrastructure (PKI), network configuration management, and the electrical power grid---we repeatedly noticed that security policies and related security artifacts...
A new type of analytic expansion for use in stability calculations is presented and applied to the question of the stability of laminar solutions of the Navier-Stokes equation. This leads in a natural way to a model of the transition from laminar...
