Part I:  Development of New Methods for Application in Multicatalytic Reactions Part II:  Investigation of Stable Carbenium Catalysts as Hydride Transfer Agents
Creators: Ambrosini Vadola, Lisa M.
Publisher: name: Columbia University
Year: 2011
Subjects: Chemistry

description: Part I of this thesis focuses on the development of novel synthetic methods and investigations into their incorporation into multicatalytic reactions. The first chapter describes the development of a bismuth(III)triflate catalyzed hydrocarboxylation reaction of unactivated alkenes to synthesize lactones. Efforts toward applying this new methodology in multicatalytic sequences are described. In the second chapter, the development of palladium(II) mediated oxidative formylation and ketonylation methods to construct complex aldehydes and ketones is presented. Investigations into the oxidative formylation mechanism revealed the formation of a stable acylpalladium hydride intermediate that could be manipulated in situ allowing for the formation of other functionality. These methods were shown to be compatible in multi-transformation processes leading to the synthesis of complex heterocyclic products in a single reaction vessel. The third chapter describes the total synthesis of members of the Tylophora alkaloid family of  molecules using a key oxidative carbonylation step. Application of a tandem palladium(II) catalyzed aminochlorocarbonylation /  indium(III) catalyzed Friedel-Crafts acylation led to the rapid construction of the key intermediate in these syntheses in a one-pot reaction. The concise syntheses of both 13a,alpha-secoantofine and antofine using this multicatalytic strategy are presented. The second part of this thesis describes the study of stable carbocations as catalysts for hydride transfer reactions. Both cyclopropenium and trityl catalysts are investigated in a reductive etherification method. A study of trityl catalyst structure and initial investigations into the development of chiral trityl catalysts are presented.
Search for a low-mass $τ^-τ^+$ resonance in association with a bottom quark in proton-proton collisions at $\sqrt{s} =$ 13 TeV

description: A general search is presented for a low-mass $τ^-τ^+$ resonance produced in association with a bottom quark. The search is based on proton-proton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The data are consistent with the standard model expectation. Upper limits at 95% confidence level on the cross section times branching fraction are determined for two signal models: a light pseudoscalar Higgs boson decaying to a pair of $τ$ leptons produced in association with bottom quarks, and a low-mass boson X decaying to a $τ$-lepton pair that is produced in the decay of a bottom-like quark B such that B $\to$ bX. Masses between 25 and 70 GeV are probed for the light pseudoscalar boson with upper limits ranging from 250 to 44 pb. Upper limits from 20 to 0.3 pb are set on B masses between 170 and 450 GeV for X boson masses between 20 and 70 GeV.

description: We study the time evolution of a single spin coupled inhomogeneously to a spin environment. Such a system is realized by a single electron spin bound in a semiconductor nanostructure and interacting with surrounding nuclear spins. We find striking dependencies on the type of the initial state of the nuclear spin system. Simple product states show a profoundly different behavior than randomly correlated states whose time evolution provides an illustrative example of quantum parallelism and entanglement in a decoherence phenomenon.

description: This paper proposes a method of auto-generation of a centerline graph from a geometrically complex roadmap of real-world traffic systems by using a hierarchical quadtree for cellular automata simulations. Our method is summarized as follows. First, we store the binary values of the monochrome image of target roadmap (one and zero represent the road and the other areas, respectively) in the two-dimensional square map. Second, we recursively divide the square map into sub-leafs by a quadtree until the summed-up value of pixels included inside the leaf becomes equal to or less than one. Third, we gradually remove the distal leaves that are adjacent to the leaves whose depths are shallower than the distal leaf. After that, we trace the remaining distal leaves of the tree using Morton's space-filling curve, while selecting the leaves that keep a certain distance among the previously selected leaves as the nodes of the graph. Finally, each selected node searches the neighboring nodes and stores them as the edges of the graph. We demonstrate our method by generating a centerline graph from a complex roadmap of a real-world airport and by carrying out a typical network analysis using Dijkstra's method.

description: This dissertation is comprised of a paper on Tristan Murail’s Mémoire/Érosion (1976) and a pair of my compositions—R[o/u]LE(s) for string quartet with percussion instruments (2016) and Projectile Motion (2018) for string quartet. The paper endeavors to draw attention to the rich, individualized voices within the French spectralist movement during its emerging phase, exemplifying various paths of en/decoding spectral thinking with Murail’s Mémoire/Érosion. In view of the interdisciplinary essence of spectralism, my analytical approach extensively adapts theories, research findings, and a posteriori knowledge from fields such as psychology, computer technology, and marketing so as to diversely reason how spectral thinking may be en/decoded by maneuvering information harnessed from the (pseudo-)spectral sources while interpreting the resultant perceptions. In comparison to the theme of the paper, which is heavily centered on pitch manipulation, the two compositions downplay such a musical dimension in varying degrees for different purposes. First, passive in nature and magnified by the incorporations of the percussion as well as the strings’ scratch tones, the reduced presence of pitch in R[o/u]LE(s) signals an attempt to navigate and investigate the topic of (Taiwanese) identity. Second, actively suppressed, pitch in Projectile Motion virtually becomes residual traces left by the heightened impulses of gesture, which, apart from being where the music largely gains its momentum, can be viewed as an expression of reflecting on issues of intimacy, accessibility, and cultural implications that contemporary music elicits in relation to a valued sector of my personal sphere.

description: Constraints on selected mediator-based dark matter models and a scalar dark energy model using up to $37~\mathrm{fb}^{-1}$ $\sqrt s = 13$ TeV $pp$ collision data collected by the ATLAS detector at the LHC during 2015-2016 are summarised in this paper. The results of experimental searches in a variety of final states are interpreted in terms of a set of spin-1 and spin-0 single-mediator dark matter simplified models and a second set of models involving an extended Higgs sector plus an additional vector or pseudo-scalar mediator. The searches considered in this paper constrain spin-1 leptophobic and leptophilic mediators, spin-0 colour-neutral and colour-charged mediators and vector or pseudo-scalar mediators embedded in extended Higgs sector models. In this case, also $\sqrt s = 8$ TeV $pp$ collision data are used for the interpretation of the results. The results are also interpreted for the first time in terms of light scalar particles that could contribute to the accelerating expansion of the universe (dark energy).

Part I: Development of Aromatic Ions as Organocatalysts Part II: Development of Organocatalytic Carbonyl Olefin Metathesis
Creators: Vanos, Christine Marie
Publisher: name: Columbia University
Year: 2012
Subjects: Chemistry

description: This thesis describes the development of novel organocatalysts within two areas of focus; aromatic ions and carbonyl olefin metathesis. The first chapter describes the extension of aromatic ion activation of alcohols to oximes for the Beckmann rearrangement. The enhanced reactivity of this reagent is discussed. The mechanism using this protocol, as well as established methods, is also considered, especially as it relates to catalysis versus initiation.
The second chapter describes the development of the first cyclopropenone-catalyzed process; chlorodehydration of alcohols. This process, which proceeds via an SN2 mechanism, is shown for a number of benzylic, allylic, propargylic, and aliphatic alcohols, resulting in high yields and complete inversion of stereochemistry, which is an improvement over traditional methods. The catalytic mechanism is also discussed.
The third chapter describes the development of a new carbonyl olefin metathesis paradigm. In contrast with traditional double bond metathesis methods, which rely on a reversible [2+2] cycloaddition, this newly developed method proceeds through a reversible [3+2] cycloaddition. Proceeding via a 1,3-dipolar cycloaddition, this novel reaction is a hydrazine-catalyzed aldehyde-olefin metathesis. The reaction design and optimization is detailed, and the current scope discussed. Control experiments and preliminary mechanism investigation have been completed and are presented.
Self-dual forms: Action, Hamiltonian and Compactification

description: It has been shown that, by adding an extra free field that decouples from the dynamics, one can construct actions for interacting 2n-form fields with self-dual field strengths in 4n+2 dimensions. In this paper we analyze canonical formulation of these theories, and show that the resulting Hamiltonian reduces to the sum of two Hamiltonians with independent degrees of freedom. One of them is free and has no physical consequence, while the other contains the physical degrees of freedom with the desired interactions. For the special cases of chiral scalars in two dimensions and chiral two form fields in six dimensions, we discuss compactification of these theories respectively on a circle and a two dimensional torus, and show that we recover the expected properties of these systems, including S-duality invariance in four dimensions.

description: Intense short-wavelength pulses from free-electron lasers and high-harmonic-generation sources enable diffractive imaging of individual nano-sized objects with a single x-ray laser shot. The enormous data sets with up to several million diffraction patterns represent a severe problem for data analysis, due to the high dimensionality of imaging data. Feature recognition and selection is a crucial step to reduce the dimensionality. Usually, custom-made algorithms are developed at a considerable effort to approximate the particular features connected to an individual specimen, but facing different experimental conditions, these approaches do not generalize well. On the other hand, deep neural networks are the principal instrument for today's revolution in automated image recognition, a development that has not been adapted to its full potential for data analysis in science. We recently published in Langbehn et al. (Phys. Rev. Lett. 121, 255301 (2018)) the first application of a deep neural network as a feature extractor for wide-angle diffraction images of helium nanodroplets. Here we present the setup, our modifications and the training process of the deep neural network for diffraction image classification and its systematic benchmarking. We find that deep neural networks significantly outperform previous attempts for sorting and classifying complex diffraction patterns and are a significant improvement for the much-needed assistance during post-processing of large amounts of experimental coherent diffraction imaging data.

Part I: Development of New Methods for Multicatalysis: Bismuth(III) Triflate-Catalyzed Hydrofunctionalizations . . .
Creators: Kelly, Brendan Douglas
Publisher: name: Columbia University
Year: 2011
Subjects: Chemistry

description: This thesis describes the development of novel synthetic methods in two areas of chemical research: Multicatalysis and the aromatic activation of alcohols. The first chapter, encompassing multicatalysis, reveals the design and realization of an innovative hydro-functionalization method. This method is examined in the context of designing multicatalytic processes to access privileged chemical architectures, which unite a nucleophilic addition event with the hydrofunctionalization reaction. The resulting multicatalytic methods capably effect the formation of complex heterocyclic compounds. The second chapter discloses an innovative paradigm for nucleophilic substitution involving aromatic cation activation of alcohols. The development of efficient chlorination and bromination methods promoted by cyclopropenium cations are discussed. The substrate scope and mechanism of the reaction are also examined. The successful demonstration of these methods established proof of concept and initiated further investigations of the aromatic cation activation strategy. The final chapter extends the concept of aromatic cation activation of alcohols to additional reaction manifolds. A dehydrative cyclization of diols employing aromatic cations is explored. The efficacy of alternative cyclopropenyl leaving groups is examined and the scope of viable nucleophiles for the aromatic activation strategy is extended. Along with Chapter 2, these seminal investigations have laid the foundation for future advances towards the realization of a general aromatic cation activation strategy.

An exploration of Muslims' perceptions and experiences of mental health, illness and treatment services
Creators: name: Verwey, Lucy
Publisher: name: Australian Catholic University
Year: 2018

description: This research involves an exploration of Muslims’ attitudes, perceptions and experiences of mental health and accessing professional treatment services. It utilised a mixed-methods design consisting of in-depth interviews and a survey. The face-to-face interviews were conducted with practising Muslims in Australia (n = 20), Indonesia (n = 8) and Jordan (n= 6). The online survey was based on the main themes which emerged from the interviews and was completed by Australian Muslim participants (N = 200). Grounded theory was employed as the underlying approach for the qualitative data collection and analysis. The results revealed three main findings. First, that Islam was central to the participants’ lives functioning as a sacred lens and sacred compass. The lens and compass provided a way for them to connect with Islamic beliefs, values and perspectives each day. This was relevant to their mental health, approaches to coping, and perspectives of effective treatment. Second, that the participants adopted distinct help seeking pathways which involved a range of religious and cultural influences. Third, the participants highlighted a need for religiously and culturally appropriate treatment for Muslim clients. In view of providing religiously and culturally appropriate treatment, key areas were identified in order to engage Muslim clients. This consisted of an underpinning knowledge of basic beliefs and practices, understanding relevant religious coping responses, and understanding the role of culture, community and family. The findings highlighted the importance of practitioners building a therapeutic relationship through trust and respect with their Muslim clients. Overall, the findings draw attention to the need for theorists, researchers and clinicians to incorporate religious perspectives of mental health and its treatment, particularly when working with Muslim clients.
Collapse and Revival of the Matter Wave Field of a Bose-Einstein Condensate

description: At the heart of a Bose-Einstein condensate lies its description as a single giant matter wave. Such a Bose-Einstein condensate represents the most "classical" form of a matter wave, just as an optical laser emits the most classical form of an electromagnetic wave. Beneath this giant matter wave, however, the discrete atoms represent a crucial granularity, i.e. a quantization of this matter wave field. Here we show experimentally that this quantization together with the cold collisions between atoms lead to a series of collapses and revivals of the coherent matter wave field of a Bose-Einstein condensate. We observe such collapses and revivals directly in the dynamical evolution of a multiple matter wave interference pattern, and thereby demonstrate a striking new behaviour of macroscopic quantum matter.

description: This thesis details the development and exploration of a catalytic carbonyl-olefin metathesis reaction. A catalytic transformation of this type has not been accomplished previously and stoichiometric processes were neither general nor desirable. A simple hydrazine catalyst was found to effect this reaction with the use of strained olefins. The development and optimization of this reaction, including the hydrazine catalyst, conditions and substrates, is discussed. Computational studies of the reaction mechanism are included. A stepwise process in which less strained olefins can undergo the reaction is also explored. Lastly, some initial explorations of transition metal complexes as catalysts for a carbonyl-olefin metathesis reaction are discussed, as well.
      	In the second portion of this thesis, the use of cyclopropenimines as achiral organic superbases will be detailed. Previously, the Lambert group has developed this class of compounds as viable catalysts for asymmetric Michael and Mannich reactions. Cyclopropenimines are more basic than other commonly used organic bases, and therefore, can activate less acidic substrates. A simple, achiral cyclopropenimine was developed for use in base catalyzed or mediated processes. Several reactions have been explored as a comparison of cyclopropenimines to other commonly used bases.

description: The scattering problems of a scalar point particle from a finite assembly of n>1 non-overlapping and disconnected hard disks, fixed in the two-dimensional plane, belong to the simplest realizations of classically hyperbolic scattering systems. Here, we investigate the connection between the spectral properties of the quantum-mechanical scattering matrix and its semiclassical equivalent based on the semiclassical zeta-function of Gutzwiller and Voros. Our quantum-mechanical calculation is well-defined at every step, as the on-shell T-matrix and the multiscattering kernel M-1 are shown to be trace-class. The multiscattering determinant can be organized in terms of the cumulant expansion which is the defining prescription for the determinant over an infinite, but trace-class matrix. The quantum cumulants are then expanded by traces which, in turn, split into quantum itineraries or cycles. These can be organized by a simple symbolic dynamics. The semiclassical reduction of the coherent multiscattering part takes place on the level of the quantum cycles. We show that the semiclassical analog of the m-th quantum cumulant is the m-th curvature term of the semiclassical zeta function. In this way quantum mechanics naturally imposes the curvature regularization structured by the topological (not the geometrical) length of the pertinent periodic orbits onto the semiclassical zeta function. However, since the cumulant limit m->infinity and the semiclassical limit hbar->0 do not commute in general, the semiclassical analog of the quantum multiscattering determinant is a curvature expanded, truncated semiclassical zeta function. We relate the order of this truncation to the topological entropy of the corresponding classical system.

description: Graphene superlattices have recently been attracting growing interest as an emergent class of quantum metamaterials. In this paper, we report the observation of nonlocal transport in bilayer graphene (BLG) superlattices encapsulated between two hexagonal boron nitride (hBN) layers, which formed hBN/BLG/hBN moiré superlattices. We then employed these superlattices to detect a long-range charge-neutral valley current using an all-electrical method. The moiré superlattice with broken inversion symmetry leads to a hot spot with Berry curvature accumulating at the charge neutral point (CNP), and it harbors satellites of the CNP. We observed nonlocal resistance on the order of 1 $\text{k}Ω$, which obeys a scaling relation. This nonlocal resistance evolves from the quantum Hall effect but without magnetic field/time-reversal symmetry breaking, which is associated with a hot-spot-induced topological valley current. This study should pave the way to developing a Berry-phase-sensitive probe to detect hot spots in gapped Dirac materials with inversion-symmetry breaking.

The benefits of biotics in erosion control materials for critical sites : better business, improved soil and stronger vegetation

description: Whether it’s the closure of a landfill cell, the remediation of strip mine slopes, or the beneficial conversion of a former industrial zone, erosion control is necessary. It is essential to establishing sustainable vegetation, which in turn protects the entire site in the long term. Increasing regulatory attention and fines have also heightened the economic pressure on agencies, site owners, contractors and other stakeholders in land development and reclamation. Biotics in erosion control products, such as the incorporation of hydraulic growth mediums (HGMs) and beneficial growth stimulants, provide organic additives that are generally missing in the soils overlying critical sites. These growth mediums provide numerous benefits to stimulate natural microbial activity, soil aggregate formation and other natural top soil forming processes and thus ensure the long-term viability and benefits of healthy vegetation. This paper describes how the introduction of specific amounts of various organic materials into HGMs has improved poor and non-native soils (such as clean fill that is transported to a site) that need an organic additive and for slope erosion prevention. With two case studies, it will show how vegetation is established quickly and sustainably for long-term, effective protection; and for the improvement of the businesses utilizing these erosion control solutions.

description: In the external field slightly inclined to the $x$- or y-axis of the frustrated tetragonal atiferromagnet Pr2CuO4, a transition is discovered from the phase with orthogonal antiferromagnetic spin subsystems along [1,0,0] and [0,1,0] to the phase with the collinear spins. This phase is shown to be due to the pseudodipolar interaction, and transforms into the spin-flop phase S perp H asymptotically at very high field. The discovered phase transition holds at T=0 and is a quantum one, with the transition field being the critical point and the angle between two subsystems being the order parameter.

description: We consider a realistic model for calculating the cross-spectral density of partially coherent beams from an x-ray undulator in a modern storage ring. This two-point coherence function is seen to have a speckled structure associated with the presence of x-ray coherence vortices and domain walls. Such cross-spectral density speckle is associated with a network of spatial pairs of points for which there is zero correlation. X-ray coherence vortices and domain walls are seen to emerge naturally as the number of coherent modes required increases. An understanding of the existence and nature of such correlation singularities enhances our ability to exploit partially coherent x-ray radiation from new or upgraded synchrotron sources, for both imaging and diffraction applications.

description: منظور از «مدیریت فرآیندهای کسب‌وکار» یا BPM، طراحی، اجرا و بهبود فعالیت‌های بین وظیفه‌ای است که اشخاص، سامانه‌های اطلاعاتی و ذی‌نفعان را به هم پیوند می‌دهد. با استفاده از ابزارهای فن‌آوری اطلاعات علاوه بر امکان مدل‌سازی، امکان شبیه‌سازی فرآیندهای مدل شده نیز وجود دارد و این امکان به‌راحتی می‌تواند گلوگاه‌های موجود در سازمان‌های مرتبط با بحث خدمت عمومی را نمایان سازد. مهندسی سازمان با توجه به پیچیدگی‌های فرآیندهای موجود در سازمان و ارتباط آن‌ها با یکدیگر تقریباً بدون استفاده از ابزارهای مدل‌سازی و شبیه‌سازی امکان‌پذیر نخواهد بود و هر چه زمان را پشت سر می‌گذاریم پیچیدگی‌های فرآیندهای سربازی بیشتر خواهد شد. سامانه‌های مدیریت فرآیندهای کسب‌وکار (BPMS - Business Process Management System) سامانه‌هایی هستند که با تلفیقی از رویکرد مدیریتی، فنّاوری و توسعه سامانه‌های کاربردی به‌عنوان یک الگوی یکپارچه‌سازی و یک پلتفرم فنی جهت مدل‌سازی و اجرای فرآیندهای کاری، مدیریت تغییرات قواعد کاری و همچنین تحلیل و ارزیابی فرآیندها و یکپارچه‌سازی با سامانه‌ها، پایگاه‌های داده‌ای و منابع اطلاعاتی موجود سازمان‌های نظامی را در بحث ارتقا بهره‌وری در بحث مدیریت نیروی سرباز می‌توانند یاری نمایند. در حال حاضر به دلیل عدم توسعه فرآیندی و عدم استقرار سامانه‌های مدیریت فرآیند در سازمان‌های نظامی و غیرنظامی دخیل در حوزه سربازی، متأسفانه شاهد میلیاردها تومان خسارات ریالی و همچنین اتلاف وقت و نیروی انسانی گران‌بهای کشور هستیم.

description: For piecewise expanding one-dimensional maps without periodic turning points we prove that isolated eigenvalues of small (random) perturbations of these maps are close to isolated eigenvalues of the unperturbed system. (Here ``eigenvalue'' means eigenvalue of the corresponding Perron-Frobenius operator acting on the space of functions of bounded variation.) This result applies e.g. to the approximation of the system by a finite state Markov chain and generalizes Ulam's conjecture about the approximation of the SBR invariant measure of such a map. We provide several simple examples showing that for maps with periodic turning points and for general multidimensional smooth hyperbolic maps isolated eigenvalues are typically unstable under random perturbations. Our main tool in the 1D case is a special technique for ``interchanging'' the map and the perturbation, developed in our previous paper, combined with a compactness argument.

Partial differential equations and variational approaches to constant scalar curvature metrics in Kähler geometry

Publisher: name: Columbia University
Year: 2015
Subjects: subject: Mathematics
subject: FOS: Mathematics

description: In this thesis we investigate two approaches to the problem of existence of metrics of constant scalar curvature in a fixed Kähler class. In the first part, we
      examine the equation for constant scalar curvature under the assumption of toric symmetry, thus reducing the problem to a fourth order nonlinear degenerate elliptic equation for a convex function defined in a polytope in ℝ^n. We obtain partial results on this equation using an associated Monge-Ampère equation to determine the boundary behavior of the solution. In the second part, we consider the asymptotics of certain energy functionals and their relation to stability and the existence of minimizers. We derive explicit formulas for their asymptotic slopes, which allows one to determine whether or not (X,L) is stable, and in some cases rule out the existence of a canonical metric.

description: Using a new approximate strong-randomness renormalization group (RG), we study the many-body localized (MBL) phase and phase transition in one-dimensional quantum systems with short-range interactions and quenched disorder. Our RG is built on those of Zhang $\textit{et al.}$ [1] and Goremykina $\textit{et al.}$ [2], which are based on thermal and insulating blocks. Our main addition is to characterize each insulating block with two lengths: a physical length, and an internal decay length $ζ$ for its effective interactions. In this approach, the MBL phase is governed by a RG fixed line that is parametrized by a global decay length $\tildeζ$, and the rare large thermal inclusions within the MBL phase have a fractal geometry. As the phase transition is approached from within the MBL phase, $\tildeζ$ approaches the finite critical value corresponding to the avalanche instability, and the fractal dimension of large thermal inclusions approaches zero. Our analysis is consistent with a Kosterlitz-Thouless-like RG flow, with no intermediate critical MBL phase.

Charge scaling and universality in critical collapse

description: Consider any 1-parameter family of initial data such that data with parameter value p > p* form black holes, and data with p < p* do not. As p -> p* from above ("critical collapse"), the black hole mass scales as M ~ (p-p*)^gamma, where the critical exponent gamma is the same for all such families of initial data. So far critical collapse has been investigated only for initial data with zero charge and zero angular momentum. Here we allow for U(1) charge. In scalar electrodynamics coupled to gravity, with action R + |(d + iqA) phi|^2 + F^2, we consider initial data with spherical symmetry and nonvanishing charge. From dimensional analysis and a previous calculation of Lyapunov exponents, we predict that in critical collapse the black hole mass scales as M ~ (p-p*)^gamma, and the black hole charge as Q ~ (p-p*)^delta, with gamma = 0.374 +- 0.001 (as for the real scalar field), and delta = 0.883 +- 0.007. We conjecture that, where there is no mass gap, this behavior generalizes to other charged matter models, with delta \ge 2 gamma. We suggest the existence of universality classes with respect to parameters such as q.

Participatory Action Research with Chinese Co-Researchers Who Have Serious Mental Illness Diagnoses

description: Engaging with marginalized communities to address issues of importance to their emotional well-being is central to counseling psychology’s core missions in social justice advocacy. Among those who have been historically viewed as deficient and marginalized are people who have been diagnosed with a serious mental illness (Schneider, 2012). Community-based psychosocial interventions have been identified as an effective form of treatment, particularly when they emphasize collaboration with community members, the empowerment of people with serious mental illnesses, the ability of such individuals to take action on behalf of themselves and others, and ownership of findings and knowledge by all partners (Corrigan & Garman, 1997; Davidson et al., 1999; Salzer, 2002). This dissertation study represents an attempt to position participatory action research (PAR) as such an intervention in the context of two marginalized identities—ethnic Chinese minority identity and the bearing of a serious mental illness diagnosis. The launching, design, and analysis of the PAR process with this population was tracked to examine the potential strengths and challenges of its utility in relation to Chinese survivors of serious mental illness. Through collaboration and dialogue, the project identified and addressed topics that the PAR co-researchers (the Chinese community members diagnosed with a serious mental illness) experienced as significant problems in their specific settings and took actions that resolved those problems, thus bridging theory and discussion topics with real-world situations, issues, and experiences, and leaving the community co-researchers and their respective agency better prepared to create such action in the future.

description: During defect-antidefect scattering, bound modes frequently disappear into the continuous spectrum before the defects themselves collide. This leads to a structural, nonperturbative change in the spectrum of small excitations. Sometimes the effect can be seen as a hard wall from which the defect can bounce off. We show the existence of these spectral walls and study their properties in the $ϕ^4$ model with BPS preserving impurity, where the spectral wall phenomenon can be isolated because the static force between the antikink and the impurity vanishes. We conclude that such spectral walls should surround all solitons possessing internal modes.
