Today''s fastest microprocessors, logic chips, and even memory chips employ dynamic logic as the key part to achieving advanced performance. Dynamic logic only retains the correct data state briefly and is far less robust than previous technologies...
Forest ecology -- Northeastern States. ; Forest canopy ecology -- Northeastern States. ; Forest dynamics -- Northeastern States.
In closed-canopy forests, changes in the relative abundance of tree species due to major disturbance or to its absence are thought to be governed principally by differences among component species in the performance of juveniles. However, few...
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...
Prostacyclin (PGI 2 ) is a major product of COX-2 catalyzed metabolism of arachidonic acid in the endothelium and has been shown to be atheroprotective. PGI 2 signals though its G-coupled protein receptor (GPCR) the human Prostacyclin receptor...
Spatial localization of sound depends on interaural time delay (ITD), level difference, and on the interaction of the source with the head, torso, and pinna. Head-related transfer functions (HRTFs) model the dynamics that are used by listeners to...
Metabolic engineering of the catabolic end-product metabolism of Thermoanaerobacterium saccharolyticum was initiated. T. saccharolyticum is an anaerobic, thermophilic bacterium that utilizes xylans and xylose, the second most prominent sugar after...
Clinical medicine -- Decision making -- Mathematical models. ; Diagnosis Laboratory. ; Medical screening -- Mathematical models. ; Osteoporosis -- Diagnosis. ; Mycobacterial diseases -- Diagnosis.
This dissertation focuses on the use of decision analysis to study the optimal use of medical tests. The classic threshold model of clinical decision making provides methodological background and motivation for the dissertation. In this model,...
Three-dimensional imaging in medicine -- Mathematical models. Diagnostic imaging -- Digital techniques. Brain -- Magnetic resonance imaging. Inverse problems (Differential equations).
An accurate registration between the preoperative images and the current surgical scene is critical to image-guided neurosurgery. However, during a neuro-surgical intervention, brain tissues shift and degrade the accuracy of the registration....
Social perception -- Physiological aspects. ; Prefrontal cortex -- Physiology.
From the most minimal of person information, such as a photograph or a sentence, people are able to rapidly infer a multitude of complex personality traits. These social inferences are thought to rely upon cognitive representations of person...
We expect wireless body-area networks of pervasive wearable devices will enable in situ health monitoring, personal assistance, entertainment personalization, and home automation. As these devices become ubiquitous, we also expect them to...
Protein phosphorylation is an important regulatory mechanism for the control of countless processes in living systems. The delicate management of phosphate attachment to, and removal from, serine, threonine and tyrosine residues in proteins...
Temperature has powerful effects on all scales of biological organization from biochemical reactions to ecosystem processes. Despite the well-appreciated influence and thorough understanding of the physiological and population consequences of...
Optical spectroscopy. Magnetic resonance imaging. Breast -- Cancer -- Imaging.
Magnetic Resonance (MR)-guided Diffuse Optical Imaging is an emerging technique to improve breast cancer imaging. This modality combines the high sensitivity of breast MR with images of tissue physiology, including blood content, oxygen saturation,...
The furanosteroid class of compounds issues a siren call to both chemists and biologists alike -- the intriguing pentacyclic skeleton, densely packed and highly functionalized, continues to entice synthetic minds to develop new and elegant methods...

The Mixed Lineage Leukemia (MLL1) gene was first cloned as a hot spot of chromosomal translocations in acute leukemia. More than 70 fusion proteins of MLL1 have been described in both lymphoid and myeloid leukemia and many are highly associated...
Limbic system -- Psychophysiology. ; Neuropsychology. ; Cell interaction.
Previous research has identified neurons in a variety of limbic structures which discharge in relation to the animals ongoing head direction (HD) (Ranck 1984; Taube et al. 1990a) or location (O''Keefe & Dostrovsky 1971). Because these signals...
The irreversible destruction of the tissues that comprise synovial joints is the hallmark of both rheumatoid arthritis and osteoarthritis. In both diseases, inflammatory cytokines, such as interleukin-1β, stimulate the production of matrix...
