description: This thesis explores the lives of indigenous women in a Bukidnon community in Negros, the Visayas, Central Philippines. It examines the political and social processes unfolding in the town of Don Salvador Benedicto and discusses how different community sectors deploy the identity politics that gives rise to conflicts between "traditional" and "modern" indigenous identities. I examine power relations and actors' subjectivity in these conflicts and use Ortner's "serious games" perspective through which "social life is seen as something that is actively played, oriented toward culturally constituted goals and projects and involving both routine practices and intentionalized action" (Ortner, 2006:129). I situate men's and women's narratives against their aspirations of uswag [progress], involving land rights and migration. The thesis discusses the unintended consequences of women's migration, including a loosening of tradition's grip on women; a breakdown of dichotomies and expansion of indigeneity; a disruption of the category of Indigenous Peoples; an increase in women's bargaining power; and changes in labour arrangements and other aspects of social relations. Migration fuelled desire for further migration especially among neighbours and other community members as well as migrants themselves, some of whom dreamt of going further away, even abroad. The thesis shows the 'dialogues' between State-imposed indigeneity and individual agency. Subjects either appropriate or reject State-imposed indigeneity by using pagbuot, roughly translated as both will and volition. Pagbuot illustrates indigeneity is a process as opposed to a fixed state of being. In the conclusion, I argue that women resort to migration to improve their lives. Migration alters their subjectivities (how subjects feel, respond, experience), and affects the dynamics of gender and indigeneity.

description: Transport phenomena are ubiquitous in nature and known to be important for various scientific domains. Examples can be found in physics, electrochemistry, heterogeneous catalysis, physiology, etc. To obtain new information about diffusive or Laplacian transport towards a semi-permeable or resistive interface, one can study the random trajectories of diffusing particles modeled, in a first approximation, by the partially reflected Brownian motion. This stochastic process turns out to be a convenient mathematical foundation for discrete, semi-continuous and continuous theoretical descriptions of diffusive transport. This paper presents an overview of these topics with a special emphasis on the close relation between stochastic processes with partial reflections and Laplacian transport phenomena. We give selected examples of these phenomena followed by a brief introduction to the partially reflected Brownian motion and related probabilistic topics (e.g., local time process and spread harmonic measure). A particular attention is paid to the use of the Dirichlet-to-Neumann operator. Some practical consequences and further perspectives are discussed.

Dreams of woken souls: the relationship between culture and curriculum
Creators: name: Caddick, Airini Rosalind Milnes
Publisher: name: University of British Columbia
Year: 2009

description: This text is a venture in honoring principles manifest within conversations for being related. It focuses upon the relationship between culture and curriculum, combining academic discourse relating to the construction of identity, policy and curriculum with conversations undertaken with 42 members of a school community in Aotearoa New Zealand; the intention being to inform the project of teaching culture. This study contributes to curriculum theory by describing a 'language' for the processes and purposes of culture in education, and by modeling the principles of that 'language.' The 'language' describes the tone for conversations for being related, the assumption being that the speakers will contribute their own vocabulary. Principles of the suggested language include the following 'tonal' qualities: • adopting a global perspective of culture that honors particularities of the local context; • incorporating many ways of knowing culture and expressing that knowing; • developing non-oppositional interpretations of cultural difference; • perceiving the teaching of culture as a collaborative, long-term, holistic project; • affirming the coexistence of change and constancy in understandings of culture; • making explicit the teacher's curricular contribution to understandings of culture; • respecting the voices of community, voices that may amend and stand alongside the academic canon. In conclusion, this study suggests that while an initial premise of fluidity and complexity in understandings of culture is present in academic and community sources, so too are principles of constancy which emphasize relatedness. In order that these principles may inform understandings of culture in the teaching of culture, a revisionary perspective is needed towards the canon (particularly the sources of knowledge to be regarded as authoritative), and towards the research, interpretation and representation of understandings of culture. The development of a 'language for being related' is suggested as one way in which teacher and researcher understandings of culture might embrace diversity and equity issues in curriculum. This project contributes to the much needed discussion on ways in which 'culture' might work to promote a philosophy of education that combines many ways of knowing in conversations for being related.

description: In recent years, our understanding of solar-like oscillations from main sequence to red giant stars has improved dramatically thanks to pristine data collected from space telescopes. One of the remaining open questions focuses around the observational identification of solar-like oscillations in pre-main sequence stars. We aim to develop an improved method to search for solar-like oscillations in pre-main sequence stars and apply it to data collected by the Kepler K2 mission. Our software APOLLO includes a novel way to detect low signal-to-noise ratio solar like oscillations in the presence of a high background level. By calibrating our method using known solar-like oscillators from the main Kepler mission, we apply it to T Tauri stars observed by Kepler K2 and identify several candidate pre-main sequence solar-like oscillators. We find that our method is robust even when applied to time-series of observational lengths as short as those obtained with the TESS satellite in one sector. We identify EPIC 205375290 as a possible candidate for solar-like oscillations in a pre-main sequence star with $ν_\mathrm{max} \simeq 242\,μ$Hz. We also derive EPIC 205375290's fundamental parameters to be $T_\mathrm{eff}$ = 3670$\pm$180 K, log $g$ = 3.85$\pm$0.3, $v$sin$i$ = 8 $\pm$ 1 km s$^{-1}$, and about solar metallicity from a high-resolution spectrum obtained from the Keck archive.

description: A new method for automated coronal loop tracking, in both spatial and temporal domains, is presented. Applying this technique to TRACE data, obtained using the 171 Angstrom filter on 1998 July 14, we detect a coronal loop undergoing a 270s kink-mode oscillation, as previously found by Aschwanden et al. (1999). However, we also detect flare-induced, and previously unnoticed, spatial periodicities on a scale of 3500km, which occur along the coronal-loop edge. Furthermore, we establish a reduction in oscillatory power for these spatial periodicities of 45% over a 222s interval. We relate the reduction in detected oscillatory power to the physical damping of these loop-top oscillations.

description: M dwarf stars are excellent candidates around which to search for exoplanets, including temperate, Earth-sized planets. To evaluate the photochemistry of the planetary atmosphere, it is essential to characterize the UV spectral energy distribution of the planet's host star. This wavelength regime is important because molecules in the planetary atmosphere such as oxygen and ozone have highly wavelength dependent absorption cross sections that peak in the UV (900-3200 $Å$). We seek to provide a broadly applicable method of estimating the UV emission of an M dwarf, without direct UV data, by identifying a relationship between non-contemporaneous optical and UV observations. Our work uses the largest sample of M dwarf star far- and near-UV observations yet assembled. We evaluate three commonly-observed optical chromospheric activity indices -- H$α$ equivalent widths and log$_{10}$ L$_{Hα}$/L$_{bol}$, and the Mount Wilson Ca II H&K S and R$'_{HK}$ indices -- using optical spectra from the HARPS, UVES, and HIRES archives and new HIRES spectra. Archival and new Hubble Space Telescope COS and STIS spectra are used to measure line fluxes for the brightest chromospheric and transition region emission lines between 1200-2800 $Å$. Our results show a correlation between UV emission line luminosity normalized to the stellar bolometric luminosity and Ca II R$'_{HK}$ with standard deviations of 0.31-0.61 dex (factors of $\sim$2-4) about the best-fit lines. We also find correlations between normalized UV line luminosity and H$α$ log$_{10}$ L$_{Hα}$/L$_{bol}$ and the S index. These relationships allow one to estimate the average UV emission from M0 to M9 dwarfs when UV data are not available.

description: A novel approach for automated high throughput NMR spectroscopy with improved mass-sensitivity is accomplished by integrating microfluidic technologies and micro-NMR resonators. A flow system is utilized to transport a sample of interest from outside the NMR magnet through the NMR detector, circumventing the relatively vast dead volume in the supplying tube by loading a series of individual sample plugs separated by an immiscible fluid. This dual-phase flow demands a real-time robust sensing system to track the sample position and velocities and synchronize the NMR acquisition. In this contribution, we describe an NMR probe head that possesses a microfluidic system featuring: i) a micro saddle coil for NMR spectroscopy and ii) a pair of interdigitated capacitive sensors flanking the NMR detector for continuous position and velocity monitoring of the plugs with respect to the NMR detector. The system was successfully tested for automating flow-based measurement in a 500 MHz NMR system, enabling high resolution spectroscopy and NMR sensitivity of 2.18 $nmol \ s^{1/2}$ with the flow sensors in operation. The flow sensors featured sensitivity to an absolute difference of 0.2 in relative permittivity, enabling distinction between most common solvents. It was demonstrated that a fully automated NMR measurement of nine individual 120 $μ$L samples could be done within 3.6 min or effectively 15.3 s per sample.

description: The high-frequency-peaked BL Lacertae object Markarian~180 (Mrk~180) was observed to have an optical outburst in 2006 March, triggering a Target of Opportunity observation with the MAGIC telescope. The source was observed for 12.4 hr and very high energy $γ$-ray emission was detected with a significance of 5.5 $σ$. An integral flux above 200 GeV of $(2.3\pm0.7)\times10^{-11} {cm}^{-2} {s}^{-1}$ was measured, corresponding to 11% of the Crab Nebula flux. A rather soft spectrum with a photon index of $-3.3\pm0.7$ has been determined. No significant flux variation was found.

Euphysilla

description: Euphysilla Kramp, 1955
Diagnosis: Hydroids like in Sphaerocoryne.
Medusa umbrella ovoid, with apical chamber; manubrium with quadratic base; mouth circular; no gastric peduncle; mature gonads surrounding the whole manubrium; four equally developed tentacles with adaxial or abaxial nematocyst clasps and a terminal cluster; ocelli absent or underdeveloped and very inconspicuous. Medusa buds on manubrium usually present.
Genetic diagnosis: 20 molecular diagnostic characters differentiate Euphysilla from other genera in the family, specifically 5 in the 16S, 9 in the COX1, 4 in the COX3, and 2 in the 18S (table 2).

Remarks: Euphysilla is very similar to Sphaerocoryne, differing only in the medusa stage by the absence or reduction of the ocelli and the frequent presence of medusa buds. Although ocelli have not been reported in Euphysilla, we noted in some of the specimens of E. pyramidata faint orange-yellow spots on the abaxial side of the tentacle bulbs, just at the position where normally ocelli would occur (fig. 4M). The spots are very inconspicuous and easily overlooked as they have the same colour as the other pigmented tissues of the medusa. It is unclear if these spots are functional ocelli. These spots were apparently overlooked by Schuchert & Collins (2021). The genus comprises currently the following species: Euphysilla peterseni Allwein, 1967, E. pyramidata Kramp, 1955, and Euphysilla tubularia Huang, Xu & Lin, 2015. The latter species appears indistinguishable from E. pyramidata (Schuchert & Collins, 2021).

description: Quantum spin liquid (QSL) represents a new class of condensed matter states characterized by the long-range many-body entanglement of topological orders. The most prominent feature of the elusive QSL state is the existence of fractionalized spin excitations. Subject to the strong quantum fluctuations, the spin-1/2 antiferromagnetic system on a kagome lattice is the promising candidate for hosting a QSL ground state, but the structurally ideal realization is rare. Here, we report Raman scattering on the single crystalline Cu$_3$Zn(OH)$_6$FBr, and confirm that the ideal kagome structure remains down to low temperatures without any lattice distortion by the angle-resolved polarized Raman responses and second-harmonic-generation measurements. Furthermore, at low temperatures the Raman scattering reveals a continuum of the spin excitations in Cu$_3$Zn(OH)$_6$FBr, in contrast to the sharp magnon peak in the ordered kagome antiferromagnet EuCu$_3$(OH)$_6$Cl$_3$. Such magnetic Raman continuum, in particular, the substantial low-energy one-pair spinon excitation serves as strong evidence for fractionalized spin excitations in Cu$_3$Zn(OH)$_6$FBr.

description: New quantum modes of the free scalar field are derived in a special time-evolution picture that may be introduced in moving charts of de Sitter backgrounds. The wave functions of these new modes are solutions of the Klein-Gordon equation and energy eigenfunctions, defining the energy basis. This completes the scalar quantum mechanics where the momentum basis is well-known from long time. In this enlarged framework the quantization of the scalar field can be done in canonical way obtaining the principal conserved one-particle operators and the Green functions.

description: N-body simulations provide most of our insight into the structure and evolution of galaxies, but our analyses of these are often heuristic and from simple statistics. We propose a method that discovers the dynamics in space and time together by finding the most correlated temporal signals in multiple time series of basis function expansion coefficients and any other data fields of interest. The method extracts the dominant trends in the spatial variation of the gravitational field along with any additional data fields through time. The mathematics of this method is known as multichannel singular spectrum analysis (M-SSA). In essence, M-SSA is a principal component analysis of the covariance of time series replicates, each lagged successively by some interval. The dominant principal component represents the trend that contains the largest fraction of the correlated signal. The next principal component is orthogonal to the first and contains the next largest fraction, and so on. Using a suite of previously analysed simulations, we find that M-SSA describes bar formation and evolution, including mode coupling and pattern-speed decay. We also analyse a new simulation tailored to study vertical oscillations of the bar using kinematic data. Additionally, and to our surprise, M-SSA uncovered some new dynamics in previously analysed simulations, underscoring the power of this new approach.

Determination of the single scattering labedo and direct radiative forcing of  biomass burning aerosol with data from the MODIS (Moderate Resolution Imaging Spectroradiometer) satellite instrument

description: Biomass burning aerosols absorb and scatter solar radiation and therefore affect the energy balance of the Earth-atmosphere system. The single scattering albedo (SSA), the ratio of the scattering coefficient to the extinction coefficient, is an important parameter to describe the optical properties of aerosols and to determine the effect of aerosols on the energy balance of the planet and climate. Aerosol effects on radiation also depend strongly on surface albedo. Large uncertainties remain in current estimates of radiative impacts of biomass burning aerosols, due largely to the lack of reliable measurements of aerosol and surface properties. In this work we investigate how satellite measurements can be used to estimate the direct radiative forcing of biomass burning aerosols. We developed a method using the critical reflectance technique to retrieve SSA from the Moderate Resolution Imaging Spectroradiometer (MODIS) observed reflectance at the top of the atmosphere (TOA). We evaluated MODIS retrieved SSAs with AErosol RObotic NETwork (AERONET) retrievals and found good agreements within the published uncertainty of the AERONET retrievals. We then developed an algorithm, the MODIS Enhanced Vegetation Albedo (MEVA), to improve the representations of spectral variations of vegetation surface albedo based on MODIS observations at the discrete 0.67, 0.86, 0.47, 0.55, 1.24, 1.64, and 2.12 ?m channels. This algorithm is validated using laboratory measurements of the different vegetation types from the Amazon region, data from the Johns Hopkins University (JHU) spectral library, and data from the U.S. Geological Survey (USGS) digital spectral library. We show that the MEVA method can improve the accuracy of flux and aerosol forcing calculations at the TOA compared to more traditional interpolated approaches. Lastly, we combine the MODIS retrieved biomass burning aerosol SSA and the surface albedo spectrum determined from the MEVA technique to calculate TOA flux and aerosol direct radiative forcing over the Amazon region and compare it with Clouds and the Earth's Radiant Energy System (CERES) satellite results. The results show that MODIS based forcing calculations present similar averaged results compared to CERES, but MODIS shows greater spatial variation of aerosol forcing than CERES. Possible reasons for these differences are explored and discussed in this work. Potential future research based on these results is discussed as well.
Someone hear my voice : one teacher’s experience integrating a child with autism into the regular classroom
Creators: name: Chalmers, Karen Louise
Publisher: name: University of British Columbia
Year: 2009

description: Many teachers are integrating children with autism into the regular classroom. Most feel unqualified and are frustrated by the lack of support. To date, there is little classroom based research that provides practical suggestions or effective practices. The purpose of this study is to explore how I, as a Family Grouping teacher sought to create an inclusive environment for one particular child with autism. I share my frustrations with all the well intentioned advice from the literature on autism and the collaborative team experts that accompanied the child to my room. But the reality was my classroom and my Family Grouping program and the children. With the use of narrative writing I attempt to capture the process of inclusion as lived by all of us. The data for the study consisted of videos, interviews, and journals collected over eighteen months and these provided a basis for the creation of the text. The study contributes to the layers of "voices" of teacher research in the area of inclusion of children with autism into the regular classroom.

description: The symmetric and gauge-invariant energy-momentum tensors for source-free Maxwell and Yang-Mills theories are obtained by means of translations in spacetime via a systematic implementation of Noether's theorem. For the source-free neutral Proca field, the same procedure yields also the symmetric energy-momentum tensor. In all cases, the key point to get the right expressions for the energy-momentum tensors is the appropriate handling of their equations of motion and the Bianchi identities. It must be stressed that these results are obtained without using Belinfante's symmetrization techniques which are usually employed to this end.

description: It has been persuasively argued that the number of the effective degrees of freedom of a macroscopic system is proportional to its area rather than to its volume. This entails interesting consequences for cosmology. Here we present a model based on this "holographic principle" that accounts for the present stage of accelerated expansion of the Universe and significantly alleviates the coincidence problem also for non-spatially flat cosmologies. Likewise, we comment on a recently proposed late transition to a fresh decelerated phase.

In this method, we consider a two-body Fermi/Bose polaron collision experiment in which impurities and atoms interact only weakly. Numerical simulations of the quantum dynamics reveal the possibility to obtain information regarding the non-local induced interaction between two polarons from a measured profile of the polaron wave packet at several snapshots. This is because the potential of the induced interaction is well balanced by the quantum potential whenever the WKB approximation for the relevant Schrödinger equation is applicable.

description: The role of the glyoxalase system in the detoxification of a - ketoaldehydes has made it an  interesting system for the development of chemotherapeutic agents. It has been shown  that inhibitors of glyoxalase I, the first enzyme in the pathway, have the ability to inhibit  murine tumor cell growth in vivo. Tumor toxicity is attributed to an increase in  intracellular concentrations of methylglyoxal, which has the ability to form DNA adducts  and prevent DNA synthesis. A new class of compound is presented here, which has the  ability to covalently modify the active site of human glyoxalase I ( hGlxI). These  compounds were predicted to be complete irreversible inhibitors of hGlxI, but the current  studies show that irreversible inhibition is limited and the enzyme is able to maintain a  fraction of its original catalytic activity. The data presented suggest that it is possible that  these compounds covalently modify only one active site of hGlxI and that the other active  site maintains a fraction of its catalytic activity. Mass spectrometry experiments show  that Cys60 is the site of covalent modification. These compounds are the first reported to  have the ability to covalently modify a residue in the active site of hGlxI. Although these  molecules are not complete irreversible inhibitors of hGlxI, they could possibly serve as  templates for the development of new compounds that may have improved potency.

description: Starting from the Kubo formula for conductance, we calculate the frequency-dependent response of a single-electron transistor (SET) driven by an ac signal. Treating tunneling processes within the lowest order approximation, valid for a wide range of parameters, we discover a finite reactive part even under Coulomb blockade due to virtual processes. At low frequencies this can be described by an effective capacitance. This effect can be probed with microwave reflection measurements in radio-frequency (rf) SET provided that the capacitance of the surroundings does not completely mask that of the SET.
description: 4 pages, 5 figures In the past few days we have noticed a serious sign error in the theory presented in this preprint, which essentially changes the sign of the capacitance correction. That is, otherwise the physics is as described, but the sign is incorrect. The new version reflects these changes

description: This note studies the behavior of Euler characteristics and of intersection homology Euler characterstics under proper morphisms of algebraic (or analytic) varieties. The methods also yield, for algebraic (or analytic) varieties, formulae comparing these two kinds of Euler characteristics. The main results are direct consequences of the calculus of constructible functions and Grothendieck groups of constructible sheaves. Similar formulae for Hodge theoretic invariants of algebraic varieties under morphisms were announced by the first and third authors in \cite{CS1, S}.

description: The Jiangmen Underground Neutrino Observatory (JUNO) is an experiment designed to study neutrino oscillations. Determination of neutrino mass ordering and precise measurement of neutrino oscillation parameters $\sin^2 2θ_{12}$, $Δm^2_{21}$ and $Δm^2_{32}$ are the main goals of the experiment. A rich physical program beyond the oscillation analysis is also foreseen. The ability to accurately reconstruct particle interaction events in JUNO is of great importance for the success of the experiment. In this work we present a few machine learning approaches applied to the vertex and the energy reconstruction. Multiple models and architectures were compared and studied, including Boosted Decision Trees (BDT), Deep Neural Networks (DNN), a few kinds of Convolution Neural Networks (CNN), based on ResNet and VGG, and a Graph Neural Network based on DeepSphere. Based on a study, carried out using the dataset, generated by the official JUNO software, we demonstrate that machine learning approaches achieve the necessary level of accuracy for reaching the physical goals of JUNO: $σ_E=3\%$ at $E_\text{vis}=1~\text{MeV}$ for the energy and $σ_{x,y,z}=10~\text{cm}$ at $E_\text{vis}=1~\text{MeV}$ for the position.

description: Cognitive dysfunction in schizophrenia is the most frequent and most stable symptom/sign over time and the degree of this dysfunction is the best predictor of long-term functional outcome. Despite impairing socio-occupational aspects of the individual and generating a burden for family and society in general, there is no effective pharmacological treatment for this cognitive dysfunction.  Advances in the field of neuroimaging have increased our understanding about cognitive processes to the extent that functional magnetic resonance imaging (MRI) has been instrumental in identifying working memory as an important factor in the cognitive dysfunction in schizophrenia. Despite the improved understanding of brain mechanisms underlying aberrant cognitive processes in schizophrenia and the numerous neurochemicals involved in its pathophysiology, there is little information as to how to link the functional neuroimaging results of working memory (WM) impairment, and the known pathophysiology in schizophrenia. An important  obstacle to understand this link is the different behaviors of the signal in the prefrontal cortex when comparing healthy and schizophrenia groups in neuroimaging studies of WM. Can different prefrontal signal behaviors(hypofrontality, hyperfrontality, both, or none) be explained by the differential WM interference caused by the interaction of the different Gamma-Aminobutryic Acid (GABA) pathology with different inter-stimulus interval (ISI) timings?  This Ph.D. work successfully answered this research question  by combining experimental functional MRI  and theoretical computational approaches. Comparing  healthy and schizophrenia groups in a functional MRI  study using a parametric manipulation of phonological and orthographic interference during a one-back task at two different ISI (1000 and 1600 milliseconds), I provided evidence that interaction of group x interference x ISI generates different prefrontal outcomes. Simulating parametric perturbations to different prefrontal GABA interneurons in a working memory model  at different ISI, I generated different outcomes of the modeled neuroimaging signal in the prefrontal cortex model. By generating different prefrontal cortex activity outcomes when comparing healthy versus schizophrenia in both approaches (experimental and theoretical), I was able to suggest a link between functional neuroimaging results and underlying pathophysiology in schizophrenia.

description: The present research focuses on the vibrational simulation of the biological systems, including the harmonic-level normal modes analysis and the anharmonic-level vibrational self-consistent field (VSCF) calculation. Normal modes analysis was performed on a large biomolecule--ricin-A-chain (RTA)--in both apo- (no substrate) and holo- (adenosine monophosphate (AMP)-bound) state. It revealed that the shearing motion was shared by both apo- and holo-RTAs, whereas the breathing motion, as well as the upward hinge and the ?-G bending characteristic motions, was dampened by substrate binding. We hypothesize that the breathing, ?-G bending and upward hinging motions play an important role in substrate binding as these motions facilitate the entry of the substrate and provide space for the substrate realignment that is necessary for the depurination. The VSCF calculations, which were typically restricted to small systems, were performed in the present research on a moderate biomolecule--the VA-class dipeptide nanotubes; to the best of our knowledge, this is the first time condensed-phase VSCF calculation of biomolecules that has been preformed. By comparing the calculated Terahertz (THz) spectra against the experimental spectra, we found that in general the VSCF level calculations deomonstrated significant improvement over the harmonic calculations, which was mostly reflected in the overall blueshifts of the VSCF frequencies from the harmonic values. These blueshifts were accounted for the coupling between two similar sidechain-squeezing modes and the subsequent stiffening of the effective potential. Finally, we developed a stochastic-VSCF methodology to enable the anharmonic and coupling-incorporated vibrational simulation for large biomolecules. This method evaluates the inter-mode couplings and performs the vibrational calculations in a stochastic fashion. During this stochastic process, the insignificantly mode pairs are rapidly found and removed from the system without exhaustively exploring the entire PES, and therefore the computational expense is remarkably saved. A validation test was performed for the stochastic-VSCF method on the VA-class dipeptide nanotubes. It was fond that this method remarkably saved the computational expense while yielding the THz spectra very close to the exhaustive VSCF calculations. The stochastic-VSCF calculation was finally performed on a large biomolecule--bacteriorhodopsin.

description: The accumulation of residual stress during welding and additive manufacturing is an important effect that can significantly anticipate the workpiece failure. In this work we exploit the physical and analytical transparency of a 1.5D model to show that the deposition of thermally expanded material onto an elastic substrate leads to the accumulation of strain incompatibility. This field, which is the source of residual stress in the system, introduces memory of the construction history even in the absence of plastic deformations. The model is then applied to describe the onset and the progression of residual stresses during deposition, their evolution upon cooling, and the fundamental role played by the velocity of the moving heat source.

description: Morphine is an extremely efficient analgesic drug however when used repetitively can have two major detrimental side effects:  tolerance and addiction.  Understanding the molecular mechanisms that lead to these side effects may ultimately help develop improved therapeutics without tolerance and addiction liability.  The goal of this dissertation was to discover candidate genes involved in morphine tolerance and addiction.  To accomplish this goal a specific behavior genetics approach in conjunction with microarray analysis was used to identify high-value candidate genes.  The genes were further investigated by bioinformatics analysis, rtPCR, and in vivo shRNA knockdown. To identify genes associated with tolerance two inbred genotypes which differ in morphine-related behaviors (C57BL/6J (B6), DBA2/J (D2)) and two reciprocal congenic genotypes (B6D2, D2B6) in which the proximal region of CH10 was introgressed into opposing backgrounds were used.  The proximal region of CH10 has been implicated in morphine related behaviors.  Tolerance following therapeutically-relevant doses of morphine developed most rapidly in the B6s followed by the B6D2s and did not develop in the D2s and only slightly in the D2B6s thus indicating a strong influence of the proximal region of CH10 in the development of tolerance.  Gene expression profiling identified 81, 96, 106, and 82 genes involved in the development of tolerance in the periaquaductal gray (PAG), prefrontal cortex (PFC), temporal lobe (TL) and ventral striatum (VS) respectively.  Bionformatics analysis highlighted genes associated with microRNA (miRNA) mechanisms in response to chronic administration. In vivo knockdown of Dicer1, the miRNA processing gene, in the PFC of the B6 genotype verified Dicer1's role in the development of tolerance.  Gene expression profiling identified 33 miRNAs involved in the development of tolerance. B6 and D2 genotypes were also used to identify candidate genes in morphine addiction.  Gene expression profiling identified total of 271 and 178 candidate genes in animals actively self-administering morphine, in the VS and ventral midbrain (VMB), respectively.  Bionformatics analysis highlighted genes associated with miRNA mechanisms and synaptic plasticity. These results indicate a significant role of miRNAs and neuroadaptation genes in tolerance and addiction. Ultimately, the candidate genes could be pharmacological targets to counteract tolerance and decrease addiction liability.
