Automatic Modeling Of Knee-Joint Motion For The Virtual Reality Dynamic Anatomy (Vrda) Tool, Yohan Baillot, Jannick P. Rolland, Kuo-Chi Lin, Donna L. Wright

Faculty Bibliography 2000s

This paper presents a method and algorithms for automatic modeling of anatomical joint motion. The method relies on collision detection to achieve stable positions and orientations of the knee joint by evaluating the relative motion of the tibia with respect to the femur (for example, flexion-extension). The stable positions then become the basis for a look-up table employed in the animation of the joint. The strength of this method lies in its robustness to animate any normal anatomical joint. It is also expandable to other anatomical joints given a set of kinematic constraints for the joint type as well as …

Association Of Beta 1 Integrin With Focal Adhesion Kinase And Paxillin In Differentiating Schwann Cells, Li-Mei Chen, Debora Bailey, Cristina Fernandez-Valle

Faculty Bibliography 2000s

Schwann cells (SCs) differentiate into a myelinating cell when simultaneously adhering to an axon destined for myelination and basal lamina. We are interested in defining the signaling pathway activated by basal lamina. Using SC/sensory neuron (N) cocultures, we identified beta 1 integrin and F-actin as components of a pathway leading to myelin gene expression and myelination (Fernandez-Valle et al., 1994, 1997). Here, we show that focal adhesion kinase (FAK) and paxillin are constitutively expressed by SCs contacting axons in the absence of basal lamina. Tyrosine phosphorylation of FAK and paxillin increases as SCs form basal lamina and differentiate. FAK and …

Electron Beam And Optical Depth Profiling Of Quasibulk Gan, L. Chernyak, A. Osinsky, G. Nootz, A. Schulte, J. Jasinski, M. Benamara, Z. Lilental-Weber, D. C. Look, R. J. Molnar

Faculty Bibliography 2000s

Electron beam and optical depth profiling of thick (5.5-64 mu m) quasibulk n-type GaN samples, grown by hydride vapor-phase epitaxy, were carried out using electron beam induced current (EBIC), microphotoluminescence (PL), and transmission electron microscopy (TEM). The minority carrier diffusion length, L, was found to increase linearly from 0.25 mu m, at a distance of about 5 mu m from the GaN/sapphire interface, to 0.63 mu m at the GaN surface, for a 36-mu m-thick sample. The increase in L was accompanied by a corresponding increase in PL band-to-band radiative transition intensity as a function of distance from the GaN/sapphire …

Feasibility Tests Of Transmission X-Ray Photoelectron Emission Microscopy Of Wet Samples, Gelsomina De Stasio, B. Gilbert, T. Nelson, R. Hansen, J. Wallace, D. Mercanti, M. Capozi, P. A. Baudat, P. Perfetti, G. Margaritondo, B. P. Tonner

Faculty Bibliography 2000s

We performed feasibility tests of photoelectron emission spectromicroscopy of wet samples in the water window (285-532 eV) soft x-ray spectral region. Water was successfully confined in an ultrahigh vacuum compatible compartment with x-ray transparent sides. This water cell was placed in the MEPHISTO spectromicroscope in a transmission geometry, and complete x-ray absorption spectra of the water window region were acquired. We also show micrographs of test samples, mounted outside of the compartment, and imaged through the water. This technique can be used to study liquid chemistry and, at least to the micron level, the microstructure of wet samples. Possibilities include …

Activation Of A Plasmodium Falciparum Cdc2-Related Kinase By Heterologous P25 And Cyclin H - Functional Characterization Of A P. Falciparum Cyclin Homologue, Karien Le Roch, Claude Sestier, Dominique Dorin, Norman Waters, Barbara Kappes, Debopan Chakrabarti, Laurent Meijer, Christina Doerig

Faculty Bibliography 2000s

Several Plasmodium falciparum genes encoding cdc2-related protein kinases have been identified, but the modalities of their regulation remains largely unexplored. Zn the present study, we investigated the regulation in vitro of PfPK5, a putative homologue of Cdk1 (cdc2) in P. falciparum. We show that (i) PfPK5 is efficiently activated by heterologous (human) cyclin H and p25, a cyclin-like molecule that specifically activates human Cdk5; (ii) the activated enzyme can be inhibited by chemical Cdk inhibitors; (iii) Pfmrk, a putative P. falciparum homologue of the Cdk-activating kinase, does neither activate nor phosphorylate PfPK5; and (iv) PfPK5 is able to autophosphorylate in …

Single Axial-Mode Selection In A Far-Infrared P-Ge Laser, A. V. Muravjov, S. H. Withers, H. Weidner, R. C. Strijbos, S. G. Pavlov, V. N. Shastin, R. E. Peale

Faculty Bibliography 2000s

Single axial-mode operation of the pulsed far-infrared p-Ge laser with an intracavity Fabry-Perot type frequency selector has been observed by means of Fourier-transform spectroscopy. A spectral resolution better than 1 GHz has been achieved on an ordinary continuous-scan spectrometer using the event-locked technique for pulsed emission sources. A laser active-cavity finesse of at least unity has been directly confirmed from the measured emission spectral width. Analysis of the envelope of the corresponding interferogram suggests that the finesse exceeds 10.

Wide-Angle, Off-Axis, See-Through Head-Mounted Display, Jannick P. Rolland

Faculty Bibliography 2000s

A 60-deg-field-of-view optical see-through head-mounted display (HMD) using off-axis optics has been designed for 3-D medical imaging visualization. Two basic on-axis optical design concepts for see-though HMDs are reviewed first, to motivate the design of an off-axis optical form. An off-axis design is then presented. Because HMDs are typically designed from the pupil of the eye to the miniature display, it is common to assess final performance according to the display characteristics. Such analysis, however, does not provide information that is easily translated into task-based performance metric. Therefore, we present an analysis of the performance of the design from a …

Optical Versus Video See-Through Mead-Mounted Displays In Medical Visualization, Jannick P. Rolland, Henry Fuchs

Faculty Bibliography 2000s

We compare two technological approaches to augmented reality for 3-D medical visualization: optical and video see-through devices. We provide a context to discuss the technology by reviewing several medical applications of augmented-reality research efforts driven by real needs in the medical field, both in the United States and in Europe. We then discuss the issues for each approach, optical versus video, from both a technology and human-factor point of view. Finally, we point to potentially promising future developments of such devices including eye tracking and multifocus planes capabilities, as well as hybrid optical/video technology.

Systems Engineering Analysis Of Aplanatic Wolter Type I X-Ray Telescopes, Patrick L. Thompson, James E. Harvey

Faculty Bibliography 2000s

It is well known that normal-incidence aplanatic telescope designs perform better at small field angles than ones corrected only for spherical aberration. This is why most large astronomical telescopes fabricated in the past fifty years have been of the Ritchey-Chretien (aplanatic) design rather than of the classical Cassegrain design. For the relatively new field of x-ray astronomy, the Welter type I grazing incidence design has been extensively utilized. It consists of a paraboloidal primary mirror coaxial with a confocal hyperboloidal secondary mirror. Aplanatic versions of the Welter type I grazing incidence x-ray telescope have been discussed in detail in the …

Clutter Modeling In Infrared Images Using Genetic Programming, Liviu I. Voicu, Mosleh Uddin, Harley R. Myler, Anthony Gallagher, Julien Schuler

Faculty Bibliography 2000s

Background clutter characterization in infrared imagery has become an actively researched field, and several clutter models have been reported. These models attempt to evaluate the target detection and recognition probabilities that are characteristic of a certain scene when specific target and human visual perception features are known. The prior knowledge assumed and required by these models is a severe limitation. Furthermore, the attempt to model subjective and intricate mechanisms such as human perception with general mathematical formulas is controversial, in this paper, we introduce the idea of adaptive models that are dynamically derived from a set of examples by a …

Modeling The Friction Effects Of Eelgrass On The Tidal Flow In Great Bay, New Hampshire, Safak Nur Erturk

Doctoral Dissertations

In this study the frictional effects of eelgrass (Zostera marina L.) on the tidal flow in Great Bay, NH is modeled using a bottom friction coefficient adjustment approach. A two-dimensional, non-linear, time stepping, finite element model, ADAM is used. ADAM model incorporates two-dimensional wave physics, with a porous medium beneath the sediment surface to simulate wetting and drying process on the tidal flats. The effectiveness of ADAM model in simulating the tidal flow in Great Bay with wetting and drying on the tidal flats is verified. The model is calibrated by adjusting the bottom friction coefficient for the M2, M2S2 …

A Comparison Of Direct Methods For Valuing Environmental Amenities: A Case Study Of The White Mountain National Forest, Wendy Harper

Doctoral Dissertations

New Hampshire's White Mountain National Forest is well known for its mountain scenery as well as its many recreational opportunities. Upcoming changes in the electric utility industry may work to change the average level of visibility in the White Mountain National Forest. While the contingent valuation method has been extensively used to value public goods (in instances such as the case above), some view the procedure with skepticism. As a result, alternative methods such as conjoint analysis have been receiving more attention. This dissertation presents the results of a face-to-face survey that attempted to directly compare conjoint analysis and contingent …

The Moses Illusion In Reading Comprehension, Anne E. Cook

Doctoral Dissertations

The Moses Illusion refers to participants' failure to detect distortions in questions such as, "How many animals of each kind did Moses take on the Ark?" although it was actually Noah's Ark. The Illusion is thought to depend on the semantic relation between the distorted term (e.g., Moses) and the correct term (e.g., Noah). The Illusion literature has been limited mostly to investigations of semantic memory and to a single-question format. The experiments reported in this dissertation examined whether the Illusion extends to longer passages of text and whether it is influenced by the presence of the correct term in …

Landscape-Scale Prediction Of Forest Productivity By Hyperspectral Remote Sensing Of Canopy Nitrogen, Marie-Louise Smith

Doctoral Dissertations

Foliar nitrogen concentration represents a direct and primary link between carbon and nitrogen cycling in terrestrial ecosystems. Although foliar N is used by many ecosystem models to predict leaf-level photosynthetic rates, it has rarely been examined as a direct scalar to stand-level carbon gain. Significant improvements in remote sensing detector technology in the list decade now allow for improved landscape-level estimation of the biochemical attributes of forest ecosystems.

In this study, relationships among forest growth (aboveground net primary productivity (ANPP) and aboveground woody biomass production (AWBP)), canopy chemistry and structure, and high resolution imaging spectrometry were examined for 88 long-term …

Modeling Plant-Soil-Atmosphere Carbon Dioxide Exchange Using Optimality Principles, Kevin Patrick Tu

Doctoral Dissertations

The exchange of carbon dioxide (CO2) between terrestrial ecosystems and the atmosphere plays a central role in the ecology of the biosphere and the climate system. Towards quantification of ecosystem-atmosphere CO 2 exchange, a generalized model of plant-soil-atmosphere CO2 exchange (OPTICAL) was described and evaluated using eddy covariance measurements of net ecosystem exchange of CO2 (NEE) in arctic, boreal, temperate, and tropical landscapes. The model requires no calibration and is based on theories of plant resource optimization and plant-soil nutrient feedbacks. The model predicts canopy photosynthetic capacity (Pcmax), canopy photosynthesis (P c), plant respiration (Rp), and soil heterotrophic respiration (RH). …

Lifers: A Study Of At -Risk Adolescent Readers, Pamela Nottage Mueller

Doctoral Dissertations

In this study I put a face and voice to the at-risk adolescent reader. No strangers to failure, these are students who by and large have struggled with reading their entire educational lives but who for whatever reason have been unable to escape the cycle of frustration in which they find themselves caught. These are students who have a great deal to say but who until now have had no forum in which to say it. These are students who deserve to be heard.

For my primary source of data, I utilized Seidman's phenomenological approach to interviewing, conducting a series …

X- And Gamma -Ray Observations Of The 15 November 1991 Solar Flare, Martina Belz Arndt

Doctoral Dissertations

This dissertation expands the current understanding of the 15 November 1991 X1.5 solar flare. This flare was a well observed event in radio to gamma-ray energies and is the first gamma-ray flare to be extensively studied with the benefit of detailed soft and hard X-ray images. In this work, we add data from all four instruments on the Compton Gamma Ray Observatory (CGRO), spanning 20 keV--300 MeV. From these data we determined that the accelerated electron spectrum above 170 keV is best fit with a power law with a spectral index gamma ≈ -4.6. We determined that the accelerated proton …

An Image Of Enduring Plurality In Economic Theory: The Root -Metaphor Theory Of Stephen C Pepper, Michael C. Daley

Doctoral Dissertations

This dissertation establishes an image of enduring plurality in economic theory based on four stable and adequate world hypotheses identified by philosopher of science Stephen C. Pepper. According to Pepper's metaphilosophy---a theory of philosophy---a world hypothesis is a conceptual system founded on a root metaphor. A root metaphor serves as a cognitive focal point or image that guides in the transformation of uncriticized, commonsense, evidence into criticized evidence and thought. A description of a world hypothesis is developed using the root-metaphor method, which derives a unique set of structural categories identified with each root metaphor. In Pepper's system, four sets …

Reading For *Class: Virginia Woolf, Rebecca West, And Sylvia Townsend Warner, Laurie Ann Quinn

Doctoral Dissertations

Reading for Class is a feminist materialist study of three twentieth-century British writers: Virginia Woolf (1882--1941), Rebecca West (1892--1983), and Sylvia Townsend Warner (1893--1978). In triangulation, Woolf, West, and Warner provide the specific grounding for the project's more general exploration of the intersections between class issues and literature. The Introduction forges the eclectic critical method defined as reading for class, and articulates the historical-political purposes of the method and of the study itself. In Chapter One, analyses of two of Woolf's lesser-known texts, the "Introductory Letter" to the collection Life as We Have Known It (1931) and Nurse Lugton's Golden …

Finite Element Modeling Of Tidal Flow And Bed -Load Transport In The Great Bay Estuarine System, New Hampshire, Ata Bilgili

Doctoral Dissertations

Current, sea level and bed-load transport are investigated in the Great Bay Estuary, New Hampshire---a shallow, well-mixed system with low freshwater input. Main channel tidal currents are over 2 m/sec, and its dynamic balance is dominated by the pressure gradient and bottom friction. Current and sea level forced by the M2, M4, M6 tides at the estuary mouth are simulated by two numerical models---a three-dimensional, harmonic model that solves the linearized shallow water equations (FUNDY5); and a vertically averaged, time stepping, non-linear model (ADAM). ADAM makes use of a kinematic assumption (that is, the local and advective accelerations are neglected) …

Carbon And Nitrogen Dynamics Of Northeastern United States Forests In Response To Environmental Stress: Measurements And Models At Local To Regional Scales, Scott V. Ollinger

Doctoral Dissertations

This thesis stems from several ongoing efforts to characterize patterns of productivity and nitrogen cycling in northeastern US forests and to address the effects of nitrogen deposition, tropospheric ozone and rising atmospheric CO2. The work reported on involves two related projects; (1) an ecosystem model analysis that integrates physiological and biogeochemical processes with important environmental variables across the northeast region and (2) a field and remote sensing analysis that examines landscape-level patterns of forest biogeochemistry in the White Mountains of New Hampshire.

Chapter 1 presents a regional analysis of forest productivity using the PnET forest ecosystem model and discusses the …

Improvements Of X-Band And Q-Band Epr /Endor Spectrometers Studies Of Ferritin Iron Nitrosyl And Copper Cis, Cis-1,3,5-Triaminocyclohexane Chloride Complexes, And The Application Of Q -Band Epr To The Dating Of Fossil Teeth, Junlong Shao

Doctoral Dissertations

Several modifications were made on a Varian Q-band EPR/ENDOR spectrometer, including the installation of a microwave amplifier in the E110 bridge, design and assembly of a new cavity coupler, addition of frequency counting capability, as well as other useful minor changes. The performance of the spectrometer was improved in signal-to-noise ratio, convenience of tuning and operation and accuracy of g-value and hyperfine coupling measurements. The signal-to-noise ratio was increased by a factor of six.

Improvements were also achieved with our X-band EPR/ENDOR spectrometer by design and assembly of a new printed ENDOR coil for use in a TE104 rectangular cavity. …

The Perceived Effects Of State -Mandated Testing In New Hampshire, Stephen A. Kossakoski

Doctoral Dissertations

The purposes of this study were: (1) to examine the perceptions of third grade teachers in the state of New Hampshire concerning the state's mandated testing program, and (2) to determine if there was a relationship between teachers' perceptions and their schools' socioeconomic status. The survey instrument designed for this study contained 61 closed response Likert scale items that measured teachers' perceptions regarding changes in curriculum and instruction, sources of pressure to improve test scores, and attitude toward the third grade test. A stratified random sample of 310 third grade teachers was selected to participate in this study. The percentage …

Shelley And The Nature Of Nonviolence, William James Stroup

Doctoral Dissertations

This is a study of the English Romantic poet and essayist Percy Bysshe Shelley's conception of the role and function of humans in the natural world, and of his influence on later reformers. Shelley's long poems Queen Mab, Laon and Cythna, and Prometheus Unbound are discussed as a trilogy where his themes of political nonviolence and protoecological awareness became integrated; also discussed at length are Mont Blanc, The Mask of Anarchy, and The Triumph of Life. The legacy of Shelley's poetry and ideas is discussed through two key figures who met in the 1880s: the now obscure Shelleyan and animal …

Rational Design And Syntheses Of 4-Phosphino-Catechol Hybrid Ligands For Mixed -Metal Clusters, Xiankai Sun

Doctoral Dissertations

Based on the concepts of Incommensurate Symmetry-Driven Cluster Formation, an approach to mixed-metal cluster formation has been proposed and realized by using the incommensurate symmetry requirements at two different metal centers bridged by a hybrid ligand. Critical to this strategy is the proper design and synthesis of hybrid ligands with coordination sites selective towards each metal. 4-Phosphino-Catechol hybrid ligands with both hard catecholate and soft phosphine donor sites have been shown to serve such a role. Three new ligands; 4-PPh2-Catechol (H2L), 4-PH2-Catechol (H2 2) and 4-P(CH2OH)2-Catechol (H23) as well as their precursors 4-PPh2-Veratrole and 4-PH2-Veratrole have been synthesized and characterized. …

Multipoint Measurements Of Large Electric Fields And Shears In The Auroral Zone, David Pietrowski

Doctoral Dissertations

This work presents results from the Auroral Turbulence II (AT II) sounding rocket launched from the Poker Flat Research Range, near Fairbanks, Alaska, on February 11, 1997. The rocket consisted of three identically instrumented payloads that reached an apogee of 550 km and flew through several arc structures in a pre-midnight auroral breakup. Three payload measurements were desired to separate the temporal from spatial aspects of auroral forms, and to investigate three dimensional flows and fields that cannot be resolved using traditional single point measurements. The focus of this study has been in the structure and changes in the dc …

Transition Metal Complexes Of Novel Ligands Derived From The Cis,Cis-1,3,5-Triaminocyclohexane (Tach) Framework: Structural And Biological Studies, Gyungse Park

Doctoral Dissertations

Transition and Group IIB metal complexes of novel ligands derived from cis,cis-1,3,5-triaminocyclohexane (tach) were prepared for structural and biological activity study. Copper(II) complexes of N,N ',N″-trialkylated derivatives of tach [Cu(tach-R3)Cl2] (R = Me, Et, Pr, furanyl, and thiophenyl) were prepared from CuCl2 in MeOH or MeOH/Et2O solvent. The structures of [Cu(tach-R3)Cl2] in the solid and solution (aqueous and methanolic) states were extensively studied by UV-vis and EPR spectroscopies and were consistent to X-ray structure of [Cu(tach-Et 3)Br0.8Cl1.2] which reveals a slightly distorted square-based pyramidal geometry. Displacement of halide ions with water molecules in aqueous media was observed by the band …
