Order picking systems -- Automation -- Computer simulation.
This research ventures into areas beyond traditional control frameworks in its focus. It integrates holonic concepts into a hierarchical control framework of a complex automated order fulfillment technology. Simulation of an actual full-scale order...
Recombinant protein production has traditionally relied on organisms with well developed molecular biological tools, such as E. coli. However, E. coli is not suited for large industrial scale production due to its propensity to produce organic...
Oligomers -- Structure -- Mathematical models. Nuclear magnetic resonance spectroscopy.
Medical Term: Nuclear Magnetic Resonance, Biomolecular.
Protein complexes play vital roles in the fundamental processes of life. In particular, homo-oligomers are involved in cell signaling, regulation, and transport. To make detailed studies of these symmetric proteins, they need to be discovered, and...
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,...

Estrogen -- Receptors -- Regulation. Selective estrogen receptor modulators. Receptor-ligand complexes. Breast -- Cancer -- Chemoprevention. Colon (Anatomy) -- Cancer -- Chemoprevention.
We have previously shown that the selective estrogen receptor modulator, Arzoxifene (Arz), and the rexinoid, LG100268 (268) synergistically prevent breast cancer in an ER+ breast cancer model. This study was designed to determine the mechanism of...
Constructibility (Set theory). Trees (Graph theory).
This thesis investigates possible initial segments of the degrees of constructibility. Specifically, we completely characterize the structure of degrees in generic extensions of the constructible universe L via forcing with Souslin trees. Then we...
Casimir effect. Zero-point field. Electric conductivity. Quantum electrodynamics.
The Casimir force arises from an alteration of boundary condition in vacuum and is often regarded as a manifestation of quantum zero point energy. Considerable progress has been made in the last decade with an impressive achievement of experimental...
This thesis presents two-fluid simulations of forced magnetic reconnection with finite electron inertia in two and three dimensional periodic systems. Reconnection in the system is driven by a spatially localized forcing function, added to the ion...
The Euler '-function and Carmichael -function are extremely important in modern number theory, and much work has been devoted to studying the distribution and arithmetic properties of the values of each function. One interesting unresolved question...
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...
The great strength of the C-F bond has enabled fluorocarbons to find many industrial and domestic applications, and makes C-F activation a chemical and technical challenge akin to that of C-H bond activation in hydrocarbons. In our mission to...
Mutualisms may facilitate coupled population expansion or decline if changes in either partner species lead to similar changes in the other species. However, few studies have measured how both species in a mutualism respond to changes in each...
Immune response -- Regulation. Tretinoin. T cells. B cells. Plasma cells. Immunity.
Adaptive immunity licenses higher organisms to generate potent immune responses against foreign antigens. Two hallmarks of adaptive immunity are A) the ability of T and B cells to distinguish self from non-self and B) the ability to mount a...
Corpus callosum -- Physiology. Cerebral hemispheres. Laterality. Sensorimotor integration. Brain -- Localization of functions.
The overarching goal of the dissertation was to further understanding of the relationship between callosal organization, functional lateralization, and interhemispheric communication in the healthy, young adult brain. Three converging methodologies...
Arabidopsis thaliana -- Physiology. Zinc -- Physiological transport. Iron -- Physiological transport. Homeostasis. Trace elements in plant nutrition.
Iron and zinc are essential metal micronutrients that most humans acquire from plant-based diets. Unfortunately, plants are not a good source of these micronutrients, so billions of people worldwide suffer from deficiencies of these two elements....
Oral infection with Toxoplasma gondii in susceptible C57BL/6 mice results in the morphologic, histologic and immunologic changes in the small intestine consistent with the human Inflammatory Bowel Disease (IBD) of unknown etiology, Crohn's disease....
Free electron lasers -- Experiments. Wave guides -- Design and construction. Diffraction gratings -- Experiments. Electron beams. Infrared sources.
The far infrared region of the electromagnetic spectrum, 15-3000 Å’Âºm in wavelength, has a paucity of narrow band laser sources. To address the issue of whether a grating based free electron laser could operate well as such a source, a grating...
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...
For a local field K, we study the affine buildings Îž n and Î” n naturally associated to SL n ( K ) and Sp n ( K ), respectively. Since Sp n ( K ) is a subgroup of SL 2 n ( K ), we investigate properties of a natural embedding of Î” n in Îž 2 n ....
Prior to biological conversion of lignocellulosic biomass, natural barriers to efficient enzymatic hydrolysis must be overcome, and a few pretreatment technologies effectively accomplish this job with chemicals. Although several factors are...
Despite years of study, the mechanisms by which cells protrude their leading edge during cell motility are still highly controversial. Two candidates for mediating this actin-based process are the Arp2/3 complex and formin family proteins. In order...
Prostacyclin (PGI2) is a major product of COX-2 derived arachidonic acid metabolism in the endothelium and uterine myometrium. Evidence indicates that PGI 2 protects against development and progression of vascular disease. While it has been known...
Evolutionary Computation (EC) is one of the most advanced computational techniques. It has been frequently and successfully used to find good solutions to many complicated optimization problems with limited computational resources. EC is the...
Riemannian manifolds. Singularities (Mathematics). Laplacian operator. Spectral theory (Mathematics). Riemann surfaces. Curves on surfaces. Geometry
Historically, inverse spectral theory has been concerned with the relationship between the geometry and the spectrum of compact Riemannian manifolds, where spectrum means the eigenvalue spectrum of the Laplace operator as it acts on smooth...
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...
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...
This thesis contains some results concerning groupoid dynamical systems and crossed products. We introduce the notion of a proper groupoid dynamical system and of its generalized fixed point algebra. We show that our notion of proper groupoid...
Forest ecology -- New Hampshire -- Hubbard Brook Experimental Forest. Lepidoptera -- New Hampshire -- Hubbard Brook Experimental Forest. Forest insects -- New Hampshire -- Hubbard Brook Experimental Forest. Insect populations -- New Hampshire --...
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...
