For a local field K, we study the affine buildings Ξ n and Δ 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 Δ n in Ξ 2 n ....
The lateral hypothalamus is a brain region involved in the regulation of feeding, glucose homeostasis, sleep/wake cycle, and autonomic nervous system (ANS). Melanin concentrating hormone (MCH) containing neurons, located in the lateral...
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 ∈ X if there is a point y ≠ x such that all null-geodesics through y pass...
We present new forensic tools that are capable of detecting traces of tampering in digital images without the use of watermarks or specialized hardware. These tools operate under the assumption that images contain natural properties from a variety...
Molecular optical imaging in vivo has potential for functional assessment of tumor tissue at the cellular and subcellular level. Advances in biological understanding of genomics and proteomics have increased the knowledge of possible cellular...
Air -- Pollution. ; Indoor air pollution. ; Air -- Pollution -- Measurement.
The polycyclic aromatic hydrocarbon (PAH) content of ambient air at several locations is described. The indoor sites examined included those having woodstoves, fireplaces, and kerosene heaters as supplements to oil heat, as well as one test home...

We provide a theoretical model for a design involving a dc voltage biased Josephson junction (JJ) that strongly drives a high quality factor microwave cavity via the ac Josephson effect. We explore the rich classical dynamics of the resultant...
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...
In this thesis we develop a theory of Fourier analysis and fast Fourier transforms (FFTs) for finite inverse semigroups. Our results generalize results in the theory of Fourier analysis for finite groups. There is a general method for generating...
Chromatin -- Structure. DNA -- Methylation. Globin genes -- Expression. Adenosine triphosphatase. Proteins -- Chemical modification.
Epigenetic regulation of gene expression is a developing field of study with many potential therapeutic applications. Chromatin remodeling is necessary for proper mammalian development, and misregulation of this process is associated with many...
Magnetic susceptibility imaging of magnetic nanoparticles (mNPs) has many potential applications in biomedicine such as contrast enhanced imaging and image guidance for magnetic hyperthermia therapy. This thesis describes three imaging methods...
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...
Drosophila melanogaster is a model organism often used when studying the complex processes of neuronal signaling and neurodegeneration. The short life cycle, malleable genetics, amenability to in vivo electrophysiological assays and sensitivity to...
Herpes simplex virus-1 (HSV-1) establishes lifelong latent infections in the sensory neurons of the trigeminal ganglia (TG) wherein it retains the capacity to reactivate. The interferon (IFN)-driven antiviral response is critical for the control of...
Information resources management -- Mathematical models. ; Database management -- Methodology. ; Change. ; World Wide Web.
Many modern information management tasks consist of an observer that must maintain current knowledge of a collection of changing information. The goal of this observer is to maintain acceptably accurate state estimates given limited observation...
Friction severely limits performance in precise positioning systems. This thesis investigates one possible approach to counter friction related performance losses, friction cancellation. In this method a friction observer is used to estimate...
Photodynamic therapy (PDT) is used to cause specific tissue destruction, using photochemical reactions that result from light excitation of photosensitizer, which has localized in the target tissue. The process of photosensitizer photobleaching was...
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...
Continual improvements to clinical breast imaging technologies have led to ever earlier detections and increasingly accurate localizations of female breast cancers. While these advancements have certainly improved the prognoses of many patients,...
Brain tissue mechanics are an important biomarker for neurological disorders, yet methods to obtain tissue information yield inconsistent conclusions. These techniques can be invasive or require excised tissue, where tissue function is altered from...
Access control is a core component of any information-security strategy. Researchers have spent tremendous energy over the past forty years defining abstract access-control models and proving various properties about them. However, surprisingly...
Liver disease of different etiologies confers significant morbidity and mortality and hence it constitutes a major health concern worldwide. Stemming from a range of causes, such as viral, drug-induced, alcoholic, or autoimmune, the rate of...
The BCL2 family of proteins control intrinsic apoptosis at the mitochondria through a delicate balance of pro and anti-apoptotic proteins. Anti-apoptotic proteins are frequently relied upon by cancer cells, making them ideal targets for...
The eukaryotic flagellum is a complex organelle that uses the force generated by dynein motors to cause beating motion of the flagellum. The central apparatus of eukaryotic flagella has been implicated in the regulation of dynein-driven motility....
We prove the existence of nontrivial multiparameter isospectral deformations of metrics on the classical compact simple Lie groups SO (n) (n = 9, n ≥11), Spin(n) (n = 9, n ≥11), SU (n) (n ≥7), and Sp (n) (n ≥5). The proof breaks into three...
Magnetic nanoparticles are promising candidates for use in biomedical applications as remote sensors of biophysical properties, thermal therapy agents, and detectors of specific biomolecules. Many approaches have been used to model magnetic...
Many kinds of cancer, and almost universally metastatic cancer, are refractory to treatment by conventional methods: surgery, radiation, and non-specific cytotoxic chemotherapy. The dawn of the age of personalized medicine presaged 15 years ago...
