description: We consider quasi-stationary (travelling wave type) solutions to a general nonlinear reaction-convection-diffusion equation with arbitrary, autonomous coefficients. The second order nonlinear equation describing one dimensional travelling waves can be reduced to a first kind first order Abel type differential equation By using two integrability conditions for the Abel equation (the Chiellini lemma and the Lemke transformation), several classes of exact travelling wave solutions of the general reaction--convection-diffusion equation are obtained, corresponding to different functional relations imposed between the diffusion, convection and reaction functions. In particular, we obtain travelling wave solutions for two non-linear second order partial differential equations, representing generalizations of the standard diffusion equation and of the classical Fisher--Kolmogorov equation, to which they reduce for some limiting values of the model parameters. The models correspond to some specific, power law type choices of the reaction and convection functions, respectively. The travelling wave solutions of these two classes of differential equations are investigated in detail by using both numerical and semi-analytical methods.

description: This thesis addresses the impact that technology has on lawyers’ ethics. It first establishes a case for place, drawing on the works of Martin Heidegger and his disciples. By analysing legal theory, ethical theory, continental philosophy and technology theory, three key elements of place emerge – location, community and history. This Heideggerian framework underpins the thesis and addresses the issues lawyers face with increased technology use. Lawyers are currently confronted by technology that has evolved as a result of globalisation. Their ethical obligations in relation to communication, confidentiality, conflicts of interest and litigation are challenged. Place affects lawyers’ ethics to a significant extent. A place based ethical perspective fills the gap within community theories of lawyers’ ethics and bridges the gap between ethical theories and technology philosophy. By recognising and preserving place, lawyers will maintain a stronger connection with their professional duties.

description: Sr2IrO4 was predicted to be a high temperature superconductor upon electron doping since it highly resembles the cuprates in crystal structure, electronic structure and magnetic coupling constants. Here we report a scanning tunneling microscopy/spectroscopy (STM/STS) study of Sr2IrO4 with surface electron doping by depositing potassium (K) atoms. At the 0.5-0.7 monolayer (ML) K coverage, we observed a sharp, V-shaped gap with about 95% loss of density of state (DOS) at EFand visible coherence peaks. The gap magnitude is 25-30 meV for 0.5-0.6 ML K coverage and it closes around 50 K. These behaviors exhibit clear signature of superconductivity. Furthermore, we found that with increased electron doping, the system gradually evolves from an insulating state to a normal metallic state, via a pseudogap-like state and possible superconducting state. Our data suggest possible high temperature superconductivity in electron doped Sr2IrO4, and its remarkable analogy to the cuprates.

description: Intrinsic localized modes or discrete breathers are investigated by molecular dynamics simulations in free-standing graphene. Discrete breathers are generated either through thermal quenching of the graphene lattice or by proper initialization, with frequencies and lifetimes sensitively depending on the interatomic potential describing the carbon-carbon interaction. In the most realistic scenario, for which temperature-dependent molecular dynamics simulations in three dimension using a graphene-specific interatomic potential are performed, the breather lifetimes increase to hundreds of picoseconds even at relatively high temperatures. These lifetimes are much higher than those anticipated from earlier calculations, and may enable direct breather observation in Raman spectroscopy experiments.
Spirits And The Ethic of Zhen: Analysis of Spirits in The Story of Purple Hairpin and The Story of Handan
Creators: name: Sheng, Yihui
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This project focuses on the two plays The Story of Purple Hairpin (Zichai Ji,
hence Purple Hairpin) and The Story of Handan (Handan Ji, hence Handan) written by
the Ming playwright Tang Xianzu (1550-1616 CE). For each play, the project takes
respectively a Confucian and a Daoist perspective to investigate how jiu, the Chinese term for
alcoholic beverages translated as spirits, manifests the ethic of zhen [sincerity, authenticity,
truth, and reality], which is the core ethic in the School of Mind (“Xinxue”) and sometimes
also demonstrated as zhenqing [sincere passion, authentic emotion, and true love]. In
Purple Hairpin, the scenes of spirits illustrate how the ethic of zhenqing overcomes Confucian
moral corruption and generates social harmony. In Handan, the scenes of spirits highlight the
ethic of zhen as the key inspiration for a commoner to realize the illusion of human world and
become a Daoist deity. The project concludes that from the ethic of zhenqing in Purple Hairpin
to the ethic of zhen in Handan, Tang suggests a process of eliminating sexual implications in
zhenqing and purifying zhen as the most cherished human ethic. In short, in both plays Tang
highlights zhen as the key solution for the moral corruption in a Confucian society and in the
entire human world.
Isotropy and control of dissipative quantum dynamics

description: We investigate the problem of what evolutions an open quantum system described by a time-local Master equation can undergo with universal coherent controls. A series of conditions are given which exclude channels from being reachable by any unitary controls, assuming that the coupling to the environment is not being modified. These conditions primarily arise by defining decay rates for the generator of the dynamics of the open system, and then showing that controlling the system can only make these rates more isotropic. This forms a series of constraints on the shape and non-unitality of allowed evolutions, as well as an expression for the time required to reach a given goal. We give numerical examples of the usefulness of these criteria, and explore some similarities they have with quantum thermodynamics.

description: This dissertation reports research on the adaptation mechanisms of the Bacterial Blight (BB) pathogen Xanthomonas oryzae pv. oryzae (Xoo) in response to its growth in rice, as well as developing a tool for monitoring this pathogen intended to facilitate the specific deployment of resistance genes for breeding. BB is one of the major diseases of rice. The negative impact of virulent forms of this pathogen on rice production has been widely reported. It has a range of adaptations which contribute to its virulence. One of the less studied aspects of the rice-Xoo interaction is the biofilm forming capability of the pathogen in the rice xylem. In this research, the genetic diversity of biofilm-related proteins in Xoo was investigated. The results show both conservation of majority of the genes, but variability in a smaller subset. This variation could be part of the adaption of the pathogen to new rice varieties or geographic locations. To determine the incremental steps in Xoo adaptation to rice, a serial passage experiment was conducted using the Philippine Xoo strain PXO61, and subsequent experiments were performed comparing the wild-type strain (designated in this study as PXO61-0) and its derivative, PXO61-4. Characterization of both PXO61-0 and PXO61-4 revealed that PXO61-4 exhibited an increase in fitness during in vitro and in planta growth. A SNP was detected by genomic comparison of both variants, which was confirmed in RNA-sequencing reads. Finally, a prototype of a single nucleotide polymorphism (SNP)-based monitoring system was developed and tested on simulated populations of Xoo. The detection pipeline successfully detected target populations in samples prepared or collected from artificial and field conditions.

description: We present a new version of the GALFORM semi-analytical model of galaxy formation. This brings together several previous developments of GALFORM into a single unified model, including a different initial mass function (IMF) in quiescent star formation and in starbursts, feedback from active galactic nuclei supressing gas cooling in massive halos, and a new empirical star formation law in galaxy disks based on their molecular gas content. In addition, we have updated the cosmology, introduced a more accurate treatment of dynamical friction acting on satellite galaxies, and updated the stellar population model. The new model is able to simultaneously explain both the observed evolution of the K-band luminosity function and stellar mass function, and the number counts and redshift distribution of sub-mm galaxies selected at 850 mu. This was not previously achieved by a single physical model within the LambdaCDM framework, but requires having an IMF in starbursts that is somewhat top-heavy. The new model is tested against a wide variety of observational data covering wavelengths from the far-UV to sub-mm, and redshifts from z=0 to z=6, and is found to be generally successful. These observations include the optical and near-IR luminosity functions, HI mass function, fraction of early type galaxies, Tully-Fisher, metallicity-luminosity and size-luminosity relations at z=0, as well as far-IR number counts, and far-UV luminosity functions at z ~ 3-6.

Pinging Fish in a Barrel: Developing a General Target Strength-Size Model for Reef Fish

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Scientific echo sounders have been in use for more than 50 years in fisheries science and management, but have a much shorter history in coral reef habitats. The great diversity of reef fish has resulted in limited understanding of the relationship between fish size and acoustic target strength in reef systems. We obtained acoustic target strengths and fish lengths for 10 different reef fish species over a range of sizes in a large aquarium to establish a general relationship between reef fish size and acoustic target strength. Two underwater digital video cameras with laser calipers were synchronized with a Simrad EK60 120 kHz split-beam echo sounder to simultaneously record the fish species, size, and target strength for a total of 400 acoustic returns. This study effectively doubles the number of fish species and increased the size range of species used to develop a target strength-length model. The improved model will enhance our interpretation of fish biomass estimates and habitat use from in situ acoustic surveys of reef ecosystems.

description: We compute the hydrodynamic torque on a dumbbell (two spheres linked by a massless rigid rod) settling in a quiescent fluid at small but finite Reynolds number. The spheres have the same mass densities but different sizes. When the sizes are quite different the dumbbell settles vertically, aligned with the direction of gravity, the largest sphere first. But when the size difference is sufficiently small then its steady-state angle is determined by a competition between the size difference and the Reynolds number. When the sizes of the spheres are exactly equal then fluid inertia causes the dumbbell to settle in a horizontal orientation.

description: Low-temperature specific heat (SH) is measured on the postannealed Ba(Fe_{1-x}Ni_x)_2As_2 single crystal with x = 0.058 under different magnetic fields. The sample locates on the overdoped sides and the critical transition temperature is determined to be 14.8 K by both the magnetization and SH measurements. A simple and reliable analysis shows that, besides the phonon and normal electronic contributions, a clear T2 termemerges in the low temperature SH data.Our observation is similar to that observed in the Co-doped system in our previous work and is consistent with the theoretical prediction for a superconductor with line nodes in the energy gap.

Nerve growth factor and chemokine receptors regulate macrophage phenotype via activation of transient receptor potential and inositol triphosphate receptor channels
Creators: name: Zhuravleva, Viktoriya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Human Immunodeficiency Virus (HIV) activates macrophages and microglia cells in the central nervous system (CNS) and triggers the secretion of neurotoxins, causing neuronal damage. Therapeutic approaches to restore cognitive function by suppressing macrophage and microglial activation have not been successful, partially due to limited knowledge of cellular mechanisms that control toxin secretion. In this investigation, we study the pathway to HIV-induced neurotoxin release, focusing on how calcium influx and phosphorylation of the HIV co-receptor CXCR4 lead to macrophage activation, including alteration of the actin cytoskeleton resulting in the formation of ruffles and podosomes. We found that Nerve Growth Factor (NGF) increases CXCR4 phosphorylation, increases calcium signaling, and reverses the HIV-induced increase in podosome formation. To further elucidate the pathway that mediates this effect, we challenged macrophages with specific inhibitors for CXCR4 and CCR5 receptors, as well as for PI3K and Pyk2. To investigate the source of calcium leading to macrophage activation, we inhibited the P2X7 receptor, CRAC channels, TrpC channels, and IP3 receptor channels. Our data indicated that calcium entry through the P2X7 receptor contributed to podosome formation while the IP3 receptor channel favored expression of the less toxic ruffled phenotype, Pyk2 signaling and calcium entry through the TrpC channel were necessary for both ruffling and podosomes. Because podosome expression is correlated with toxin secretion from macrophages, determining the pathway to morphological modifications enables a better overall understanding of macrophage activation. This knowledge can lead to better regulation of macrophages and control of inflammation in the CNS.

description: We investigate gauge invariant scalar fluctuations of the metric during inflation in a non-perturbative formalism in the framework of a recently introduced scalar-tensor theory of gravity formulated on a Weyl-Integrable geometry. We found that the Weyl scalar field can play the role of the inflaton field in this theory. As an application we study the case of a power law inflation. In this case the quasi-scale invariance of the spectrum for scalar fluctuations of the metric is achieved for determined values of the $ω$ parameter of the scalar-tensor theory. In our formalism the physical inflaton field has a geometrical origin.

description: The beam energy measurement system is of great importance and profit for both BEPC-II accelerator and BES-III detector. The system is based on measuring the energies of Compton back-scattered photons. Many advanced techniques and precise instruments are employed to realize the highly accurate measurement of positron/electron beam energy. During five year's running period, in order to meet the requirement of data taking and improve the capacity of measurement itself, the upgradation of system is continued, which involve the component reformation of laser and optics subsystem, replacement of view-port of the laser to vacuum insertion subsystem, the purchase of electric cooling system for high purity germanium detector, and the improvement of data acquisition and processing subsystem. The upgrading of system guarantees the smooth and efficient measuring of beam energy at BEPC-II and accommodates the accurate offline energy values for further physics analysis at BES-III.

Clean hands, clean stethoscope: Increasing stethoscope hygiene among nursing students through training
Creators: name: Detert, Nickolai C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Background: Hospital-acquired infections are a source of mortality and financial drain on healthcare systems and families, and all potential vectors of pathogen transmission must be identified. The stethoscope is an often overlooked piece of equipment common in healthcare that can transmit disease. After handwashing was found to dramatically reduce infection, rigorous handwashing training became common and culture shifted. This project introduced training new nursing students in stethoscope hygiene procedures to determine if their awareness and practices would change to include cleaning their stethoscopes compared to students who did not receive the intervention.
Method: New nursing students were given pre- post-intervention surveys to compare baseline knowledge before and after stethoscope hygiene was introduced into their curriculum as an evaluated skill. Students were observed in skills labs to evaluate skill transfer. As a comparison group, senior nursing students not given the training were given a single survey to determine baseline knowledge. They were observed in clinical rotations for evidence of the application of stethoscope hygiene.
Results: Students given the training showed significant increase in awareness of stethoscope hygiene post-intervention and a significant number applied the skill in encounters with simulated patients. Students not given the training showed lower levels of both awareness and utilization of the skill.
Conclusions: Stethoscope hygiene training does lead to increased awareness and use of the skill, and should be instituted in healthcare training to potentially increase compliance in the healthcare environment.

description: We report both zinc-blende (ZB) and wurtzite (WZ) crystal phase self-assembled GaAs quantum dots (QDs) embedding in a single GaAs/AlGaAs core-shell nanowires (NWs). Optical transitions and single-photon characteristics of both kinds of QDs have been investigated by measuring photoluminescence (PL) and time-resolved PL spectra upon application of hydrostatic pressure. We find that the ZB QDs are of direct band gap transition with short recombination lifetime (~1 ns) and higher pressure coefficient (75-100 meV/GPa). On the contrary, the WZ QDs undergo a direct-to-pseudodirect bandgap transition as a result of quantum confinement effect, with remarkably longer exciton lifetime (4.5-74.5 ns) and smaller pressure coefficient (28-53 meV/GPa). These fundamentally physical properties are further examined by performing state-of-the-art atomistic pseudopotential calculations.

From Fringe to Mainstream: Understanding the Cultural and Political Identities of Contemporary German Nationalism
Creators: name: Jackson-Irwin, Jasmine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Although far-right politics remains a fringe movement in contemporary Germany,
one can observe its continuing presence in society given the rise of the National Democratic
Party (NPD) in the early 2000s, and the violent attacks led by the National Socialist
Underground (NSU) from 2000-2006. A divided opinion amongst Germans arises regarding
how best to address nationalism: should the state mandate an outright ban on all nationalist
groups, or foster a system that allows for close observation and monitoring of said groups?
Nonetheless, the nuanced elements of the far-right movement make it increasingly difficult to
achieve a definitive solution. While encompassing less than 1% of the population, supporters
of the far-right often possess distinctly cultural or political identities that compromise the
overall efficacy and legitimacy of the movement.
Given ambiguous rates of support due to these conflicting identities, as well as the
isolation of right-wing groups and individuals in specific regions, how has the contemporary
right-wing achieved such widespread publicity? More importantly, to what degree does this
movement pose a threat to German democracy? In this thesis, I provide an interdisciplinary
review of film (Dennis Gansel’s Die Welle), literature (Andres Veiel’s Der Kick and Timur
Vermes’ Er ist wieder da), journalism, and government publications to identify the societal
implications of the contemporary far-right in Germany. Specifically, I seek to address how,
if at all, these cultural representations of far-right ideology mirror the actual movement, and
to what extent this movement may subvert established German democracy.

Year: 2019

description: This thesis examines the effects of exile on the life and music of Sergei Rachmaninoff and how those effects might inform the way Rachmaninoff and composers like him are incorporated into the historical narrative of twentieth-century music. The first chapter concerns Rachmaninoff's life, particularly his experience in exile, but also his musical influences and experiences in pre-Revolutionary Russia. The second chapter is a case study of Rachmaninoff's final work, the Symphonic Dances, Opus 45, a detailed analysis of which aims to show how the composer's musical style synthesized his pre-exile musical influences and his contemporary musical context.

description: We study an extension of the Standard Model featuring a hidden sector that consists of a new scalar charged under a new SU$(N)_D$ gauge group, singlet under all Standard Model gauge interactions, and coupled with the Standard Model only via a Higgs portal. We assume that the theory is classically conformal, with electroweak symmetry breaking dynamically induced via the Coleman-Weinberg mechanism operating in the hidden sector. Due to the symmetry breaking pattern, the SU$(N)_D$ gauge group is completely Higgsed and the resulting massive vectors of the hidden sector constitute a stable dark matter candidate. We perform a thorough scan over the parameter space of the model at different values of $N=2$, $3$, and $4$, and investigate the phenomenological constraints. We find that $N=2,3$ provide the most appealing model setting in light of present data from colliders and dark matter direct search experiments. We expect a heavy Higgs to be discovered at LHC by the end of Run II or the $N=3$ model to be ruled out.

description: Carbon nanotubes have been observed to emit ultraviolet, visible and infrared radiation when exposed to microwaves. We have performed experiments in which both short (0.5 microns to 2 microns) and long (5 microns to 30 microns) single and double walled carbon nanotubes were exposed to 2.46 GHz microwaves at a pressure of 10^-6 Torr. Structural modifications of the-carbon nanotubes due to microwave absorption have been studied using the Raman spectroscopy G-band and D-band intensities, which suggest that microwave irradiation at relatively low pressure results in an increase in nanotube defects, especially in the case of the long nanotubes. Furthermore, a comparison of the spectra of the radiation emitted from the nanotubes suggests that the longer nanotubes emitted radiation of much greater intensity than the shorter nanotubes. Based on the results of the experiments and results described in previous reports, the ultraviolet, visible and infrared radiation emitted as the result of microwave absorption by carbon nanotubes seems to be primarily blackbody radiation emitted due to Joule heating. However, the presence of several broad photopeaks in the spectra of the emitted radiation (which do not seem to be related to gases absorbed by the nanotubes or the presence of catalyst particles) suggest that emissions are not the result of Joule heating alone.

description: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy with a
consistently poor prognosis (<7% five-year survival rate). Oncogenic KRAS is the primary
driver of PDAC, present in ~95% of cases, and has been previously shown to upregulate GMCSF,
a cytokine contributing to a pro-tumorigenic, immunosuppressive microenvironment in the
pancreas via MDSCs (myeloid-derived suppressor cells). Additionally, Rab27a mediated
exosome secretion can also initiate a pre-metastatic niche in the liver, priming them for tumor
infiltration through macrophage recruitment. In this project, stable knockdowns were generated
for Rab27a in pancreatic ductal epithelial cells from KPC mice (KPC PDECs) and injected back
into the pancreata of mice to determine metastatic potential. After harvesting and analyzing the
livers by flow cytometry and histology, initial data shows a reduction of MDSCs but not in
macrophages, suggesting a way by which Rab27a can mediate formation of a pre-metastatic
niche. Stable knockdowns for GM-CSF are in the process of being generated for similar analysis.

description: Magneto-transport properties in closed and open loop structures are carefully reviewed within a tight-binding formalism. A novel mesoscopic phenomenon where a non-vanishing current is observed in a conducting loop upon the application of an Aharonov-Bohm flux $ϕ$ and we explore its behavior in the aspects of quantum phase coherence, electron-electron correlation and disorder. The essential results are analyzed in three different parts. First, we examine the behavior of persistent current in different branches of a zigzag carbon nanotube within a Hartree-Fock mean field approach using the second quantized formulation. The phase reversal of persistent current in several branches as a function of Hubbard interaction is found to exhibit interesting patterns. Our numerical results suggest a filling-dependent metal-insulator transition in a zigzag carbon nanotube. Next, we address the behavior of persistent current in an ordered-disordered separated nanotube keeping in mind a possible experimental realization of shell-doped nanowire which can provide a strange electronic behavior rather than uniformly doped nanowires. Finally, we focus our attention on the behavior of persistent current in an open loop geometry where we clamp an ordered binary alloy ring between two ideal semi-infinite electrodes to make an electrode-ring-electrode bridge. From our investigation we propose that under suitable choices of the parameter values the system can act as a $p$-type or an $n$-type semiconductor.

description: Η παρούσα διπλωματική εργασία έχει ως στόχο την αναζωογόνηση της πολιτιστικής ζωής και τη βελτίωση της συνολικής βιωματικής εμπειρίας στον οικισμό της Άσσου, Κεφαλληνίας. Η επέμβαση γίνεται σε ένα κομβικό σημείο του χωριού, που σηματοδοτεί το τέλος του οικισμού και ταυτόχρονα αποτελεί κατώφλι για το ιστορικό ενετικό κάστρο της Άσσου. Στο σημείο αυτό, προτείνεται η μετατροπή του υφιστάμενου, άτυπου χώρου στάθμευσης σε δημόσια πλατεία, με σκοπό τη δημιουργία ενός ευέλικτου χώρου που θα λειτουργεί ως σημείο αναφοράς, αποτελώντας μια σημαντική στάση για τους κατοίκους και τους επισκέπτες, ενώ παράλληλα θα φιλοξενεί πολιτιστικά δρώμενα τοπικής και υπερτοπικής σημασίας. Ταυτόχρονα προτείνεται, εκεί, η δημιουργία ενός πολιτιστικού κέντρου, που θα αναγερθεί στα ίχνη ενός παλιού τουριστικού περιπτέρου για να στεγάσει εκθέσεις, εργαστήρια, παραστάσεις και άλλες πολιτιστικές εκδηλώσεις, ενώ παράλληλα θα αποτελεί και ενημερωτικό χώρο για την ιστορία του οικισμού και του κάστρου. Η τοποθέτηση του πολιτιστικού κέντρου στη συγκεκριμένη θέση θα λειτουργήσει συμβολικά στη μνήμη των κατοίκων, αντικαθιστώντας το ερειπωμένο κτίριο που υποβάθμιζε τον χώρο επί χρόνια, με μια ζωντανή δομή προσβάσιμη σε όλους.
description: This thesis aims to revitalize the cultural life and improve the entire experience in the village of Assos, Kefalonia. The intervention takes place at a key point of the village, which marks both the end of the residential area and the entrance to the historic Venetian castle of Assos. In this area, it is proposed the conversion of the existing, informal parking area into a public square, in order to create a flexible space that will function as a reference point, becoming an important attraction for residents and visitors, while hosting cultural events of local and inter-regional importance. At the same time, the creation of a cultural centre is proposed there, which will be raised on the traces of an old tourist pavilion to host exhibitions, workshops, performances and other cultural events, while at the same time it will be an informative space for the history of the village and the castle. The placement of the cultural centre in this location will act in a symbolic way on the residents' memory, replacing the desolate building that has been degrading the area for years with a vivid structure accessible to all.
Embedding a nondiffracting defect site in helical lattice wave-field by optical phase engineering

description: We present a technique to optically induce a defect site in helical lattice wave-field where the combined wave-field continues to maintain its nondiffracting (ND) nature. This is done by coherently superposing a helical lattice wave-field and a Bessel beam by method of phase engineering. The results are confirmed by numerical simulations and experimentally as well by generating the ND defect beam by displaying the numerically calculated phase pattern on a phase-only spatial light modulator. This technique is wavelength independent, completely scalable, and can easily be used to generate or transfer these structures in any photosensitive medium.

description: Typical sources of ultracold atoms operate with a considerable delay between the delivery of ensembles due to sequential trapping and cooling schemes. Therefore, alternative schemes for the continuous generation of ultracold atoms are highly desirable. Here, we demonstrate the continuous loading of a magnetic trap from a quasi-continuous atom beam. We achieve a steady state with $3.8 \times 10^7$ magnetically trapped atoms and a temperature of $102 μ$K. The ensemble is protected from laser light sources, a requirement for its application for metrological tasks or sympathetic cooling. The continuous scheme is robust and applicable to a wide range of particles and trapping potentials.

description: The Bayesian approach to Inverse Problems relies predominantly on Markov Chain Monte Carlo methods for posterior inference. The typical nonlinear concentration of posterior measure observed in many such Inverse Problems presents severe challenges to existing simulation based inference methods. Motivated by these challenges the exploitation of local geometric information in the form of covariant gradients, metric tensors, Levi-Civita connections, and local geodesic flows, have been introduced to more effectively locally explore the configuration space of the posterior measure. However, obtaining such geometric quantities usually requires extensive computational effort and despite their effectiveness affect the applicability of these geometrically-based Monte Carlo methods. In this paper we explore one way to address this issue by the construction of an emulator of the model from which all geometric objects can be obtained in a much more computationally feasible manner. The main concept is to approximate the geometric quantities using a Gaussian Process emulator which is conditioned on a carefully chosen design set of configuration points, which also determines the quality of the emulator. To this end we propose the use of statistical experiment design methods to refine a potentially arbitrarily initialized design online without destroying the convergence of the resulting Markov chain to the desired invariant measure. The practical examples considered in this paper provide a demonstration of the significant improvement possible in terms of computational loading suggesting this is a promising avenue of further development.

Social Problem Solving in Adolescents Engaging in Non-Suicidal Self-Injury Compared with Adolescent Suicide Attempters
Creators: name: Cheek, Shayna M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The aim of the present study was to examine social problem solving skills among adolescents engaging in various self-injurious behaviors. Previous research has supported the claim that deficits in social problem solving skills are associated with engagement in non-suicidal self-injury (NSSI) and suicide attempts, but no research has been done comparing the two self-injury groups together. Data was collected from 176 adolescent females with history of mental health problems measuring their self-injurious behaviors and social problems solving skills. After answering various questions regarding their social problem solving skills over four social scenarios, participants experienced a stressful task and were then given the remaining four social scenarios. This manipulation was intended to simulate a state of high arousal – more like their physical state would be in the event a social problem had just occurred. Results suggested that adolescents who had reported attempting suicide experienced greater increases in avoidant problem solving strategies after the stressful task than adolescents who had only engaged in NSSI or those who had never injured themselves for any purpose. Implications of these findings, limitations of the current study, and directions for future research are discussed.

description: Comparison of morphological modules using four methods. A) Principal component analysis (PCA) using scaled linear morphometrics (as shown in main text Fig. 3A); B) PCA using unscaled linear morphometrics; C) Principal coordinate analysis (PCoa) including pre-zygapophyseal angle (PZA) using scaled linear morphometrics; D) PCoa including PZA using unscaled linear morphometrics. Red text indicates species with differences in modularity between scaled and unscaled linear morphometrics. The third cervical vertebra was not included in the PCoa analyses because PZA at C3 could not be reliably measured in some taxa.
