Microfabricated electromagnetic actuators for confocal measurements and imaging
Creators: name: Mansoor, Hadi
Publisher: name: University of British Columbia
Year: 2013

description: Various optical microscopy techniques have been developed for micrometer level imaging of biological tissue samples. Among those techniques, confocal imaging provides superior image contrast and high resolution with a modest system cost. Confocal microscopy allows vertical optical sectioning (imaging a section perpendicular to the surface of tissue) or horizontal optical sectioning (imaging a section parallel to the surface of tissue) and provides high-resolution tissue morphology that is analogous to conventional histopathology images. This has brought up a tremendous potential for guiding surgical biopsies and in vivo non-invasive diagnosis of diseases such as cancer. The challenge in moving microscopic imaging modalities into clinical applications is miniaturization into a form of hand-held devices or catheters for endoscopic applications. In this thesis, micro-fabrication techniques such as Microelectromechanical Systems (MEMS) fabrication process and laser micromachining have been employed to develop magnetic actuators. The actuators are then used to move lenses and optical fibers in order to scan a laser beam across a sample. Lens and fiber actuators are integrated in catheter and hand-held devices for confocal thickness measurement and optical sectioning imaging of biological samples. Thickness measurement is performed by scanning the focal point of a microlens across the thickness of thin films or layered biological tissues and collecting the intensity signal of the single scattering light reflected back from the samples as a function of lens position. A catheter was developed and thickness measurements of polymer layers and biological tissues were demonstrated. The device has optical resolution of 32 µm with expanded uncertainty of measurement of 11.86 µm. Lens and fiber optic actuators have been coupled to form two-dimensional imaging devices. Direct and real-time vertical and horizontal cross-sectional imaging of biological samples has been demonstrated. Vertical imaging is performed by transverse (X-axis) and axial (Z-axis) scanning of a focused laser beam using an optical fiber and a microlens actuator respectively. Horizontal imaging is done by a 2-axis fiber optic scanner. All the developed actuators are driven by electromagnetic forces and require low driving voltages. Confocal imaging of biological samples, with lateral resolution of 1.55 µm, has been demonstrated.

description: Dynamical spin structure factors of quantum spin nematic states are calculated in a spin-1/2 square-lattice J1-J2 model with ferromagnetic J1 and competing antiferromagnetic J2 interactions. To this end, we use a fermion representation, generalizing it to N flavors. We begin with a spin-triplet pairing state of fermion fields, called Z2 planar state, which is a stable saddle-point solution in the large-N limit in a finite parameter range where the couplings J1 and J2 compete strongly [R. Shindou and T. Momoi, Phys. Rev. B 80, 064410 (2009)]. Using a large-N expansion, we take into account fluctuations around this saddle point up to corrections of order 1/N. The dynamical spin structure factors thus obtained signify the existence of gapless q-linear director-wave (spin-wave) modes at q=(0,0) and gapped `gauge-field' like collective modes at q=(pi,pi), whose spectral weight vanishes as a linear and quadratic function of the momentum respectively. The low-energy collective modes contain fluctuations of nematic-director, spin, and gauge degrees of freedom. Associated with the gapless q-linear modes, we evaluate the temperature dependence of the nuclear spin relaxation rate 1/T1 in the low-temperature regime as 1/T1 \propto T^{2d-1}, where d is the effective spatial dimension.

Embedding laws in diffusions by functions of time

Subjects: subject: Probability (math.PR)

description: We present a constructive probabilistic proof of the fact that if $B=(B_t)_{t\ge0}$ is standard Brownian motion started at $0$, and $μ$ is a given probability measure on $\mathbb{R}$ such that $μ(\{0\})=0$, then there exists a unique left-continuous increasing function $b:(0,\infty)\rightarrow\mathbb{R}\cup\{+\infty\}$ and a unique left-continuous decreasing function $c:(0,\infty)\rightarrow\mathbb{R}\cup\{-\infty\}$ such that $B$ stopped at $τ_{b,c}=\inf\{t>0\vert B_t\ge b(t)$ or $B_t\le c(t)\}$ has the law $μ$. The method of proof relies upon weak convergence arguments arising from Helly's selection theorem and makes use of the Lévy metric which appears to be novel in the context of embedding theorems. We show that $τ_{b,c}$ is minimal in the sense of Monroe so that the stopped process $B^{τ_{b,c}}=(B_{t\wedgeτ_{b,c}})_{t\ge0}$ satisfies natural uniform integrability conditions expressed in terms of $μ$. We also show that $τ_{b,c}$ has the smallest truncated expectation among all stopping times that embed $μ$ into $B$. The main results extend from standard Brownian motion to all recurrent diffusion processes on the real line.

description: The stifling Argentinean dictatorship has elicited a series of reflections on Argentineans's cultural roots and, at the same time, it has called into question the notion of Argentinean exceptionalism. All this has brought to re-think and to re-evaluate the migratory past of Argentina, especially in light of the economic policy of the country that lead to the 2001 default. The political and economic events have had their reflections on the literary production, in particular on memoirs and pseudo-memoirs. The object of my essay is the work of AntonioDal Masetto, mostly known for his novels about migration. In particular, I will focus on his most recent writing in which the condition of the migrant is no longer a personal and familial concern but it becomes a contemporary and universal paradigm. For the purpose of my essay, I will use the by-now classic theories of Edouard Glissant, Jacques Derrida and Loretta Baldassar about migration.

Advances in the evaluation of informal settlement upgrading in Brazil
Creators: name: White, Tamara
Publisher: name: University of British Columbia
Year: 2013

description: This thesis focuses on the practice of evaluation of informal settlement upgrading projects in Brazil. The country experienced a wave of rapid urbanization over the last sixty years, with eighty-four percent of the population now living in cities. As cities lacked affordable housing options commensurate with their burgeoning populations, informal settlements proliferated. Over several decades, policy responses have evolved to promoting the upgrading of these settlements. A wide variety of strategies has been employed to address the material, social, and legal issues associated with informal settlements. The actors have been equally diverse, including federal and municipal government, NGOs, international agencies, and community-based organizations. After more than a generation of concerted trial and error in designing and implementing upgrading programs, how have monitoring and evaluation practices been put to use? Grounded in an understanding of global urbanization trends and current debates around the practice of monitoring and evaluation, this study aims to: 1. Establish the importance of monitoring and evaluation as a critical element in improving the outcomes of upgrading and building an international body of knowl¬edge around effective upgrading programs; 2. Assess the current practice of monitoring and evaluation of upgrading programs in Brazil; 3. Identify the challenges and barriers that currently impede the broad usage of such evaluation systems, and; 4. Identify the national trends that point to increased use of monitoring and evaluation in the future. This research finds that systematic monitoring and evaluation of the development outcomes of upgrading programs rarely occurs. Academics and researchers conduct a wide range of evaluative studies, though these tend to be isolated and non-continuous. International donor agencies, and more recently the federal government, require project evaluations be conducted on particular projects, though these tend to remain at the level of project outputs. Many trends, however, indicate that the nascent practice of monitoring and evaluation is attracting increased interest from policy-makers, practitioners, scholars and stakeholders. It is concluded that M&E practice will continue to be refined and experience broader application in the coming years.

description: DNA origami nanostructures allow for the arrangement of different functionalities such as proteins, specific DNA structures, nanoparticles, and various chemical modifications with unprecedented precision. The arranged functional entities can be visualized by atomic force microscopy (AFM) which enables the study of molecular processes at a single-molecular level. Examples comprise the investigation of chemical reactions, electron-induced bond breaking, enzymatic binding and cleavage events, and conformational transitions in DNA. In this paper, we provide an overview of the advances achieved in the field of single-molecule investigations by applying atomic force microscopy to functionalized DNA origami substrates.

description: Elastic wave propagation is studied in a heterogeneous 2-D medium consisting of an elastic matrix containing randomly distributed circular elastic inclusions. The aim of this study is to determine the effective wavenumbers when the incident wavelength is similar to the radius of the inclusions. A purely numerical methodology is presented, with which the limitations usually associated with low scatterer concentrations can be avoided. The elastodynamic equations are integrated by a fourth-order time-domain numerical scheme. An immersed interface method is used to accurately discretize the interfaces on a Cartesian grid. The effective field is extracted from the simulated data, and signal-processing tools are used to obtain the complex effective wavenumbers. The numerical reference solution thus-obtained can be used to check the validity of multiple scattering analytical models. The method is applied to the case of concrete. A parametric study is performed on longitudinal and transverse incident plane waves at various scatterers concentrations. The phase velocities and attenuations determined numerically are compared with predictions obtained with multiple scattering models, such as the Independent Scattering Approximation model, the Waterman-Truell model, and the more recent Conoir-Norris model.

description: Using scanning tunneling spectroscopy we have measured the response of Dirac electrons in a magnetic field to the presence of a well-defined smoothly varying 1D periodic potential. We find that the lower index Landau level energies reliably trace the potential variations, while the higher index levels appear surprisingly homogeneous. Modeling the effects of the periodic potential on the Landau level spectra, we show that the Landau level behavior encodes information on the spatial extent of the wavefunctions. The lower index maps reveal Landau level stripes, which would act as traps for chiral one-dimensional modes. Our findings have important implications for transport and magneto-resistance measurements in Dirac materials with engineered potential landscapes.

In particular, K-theory spaces admit canonical (connective) deloopings, and the K-theory functor enjoys a universal property. Using this, we give new, higher categorical proofs of both the additivity and fibration theorems of Waldhausen. As applications of this technology, we study the algebraic K-theory of associative ring spectra and spectral Deligne-Mumford stacks.

description: Pressure plays an essential role in the induction1 and control2,3 of superconductivity in iron-based superconductors. Substitution of a smaller rare-earth ion for the bigger one to simulate the pressure effects has surprisingly raised the superconducting transition temperature Tc to the record high 55 K in these materials4,5. However, Tc always goes down after passing through a maximum at some pressure and the superconductivity eventually tends to disappear at sufficiently high pressures1-3. Here we show that the superconductivity can reemerge with a much higher Tc after its destruction upon compression from the ambient-condition value of around 31 K in newly discovered iron chalcogenide superconductors. We find that in the second superconducting phase the maximum Tc is as high as 48.7 K for K0.8Fe1.70Se2 and 48 K for (Tl0.6Rb0.4)Fe1.67Se2, setting the new Tc record in chalcogenide superconductors. The presence of the second superconducting phase is proposed to be related to pressure-induced quantum criticality. Our findings point to the potential route to the further achievement of high-Tc superconductivity in iron-based and other superconductors.

description: Parity violation found in the Cosmic Microwave Background (CMB) radiation is a crucial clue for the non-standard cosmological model or the possible contamination of various foreground residuals and/or calibration of the CMB data sets. In this paper, we study the directional properties of the CMB parity asymmetry by excluding the $m=0$ modes in the definition of parity parameters. We find that the preferred directions of the parity parameters coincide with the CMB kinematic dipole, which implies that the CMB parity asymmetry may be connected with the possible contamination of the residual dipole component. We also find that such tendency is not only localized at $l=2,3$, but in the extended multipole ranges up to $l\sim 22$.

Issue indivisibility as an explanatory model for the Arab Spring
Creators: name: Halderman, Frank Douglas
Publisher: name: University of British Columbia
Year: 2013

description: This thesis examines the Arab Awakening in four countries—Tunisia, Egypt, Libya and Syria—and argues that Ron Hassner’s model of issue indivisibility (2009) rather than James Fearon’s model of the commitment problem (2004) provides the best explanation for these uprisings. In each case, the presidency and control of the nation is best described as a super-valuable good, which was considered to be essentially indivisible by state and non-state actors. The presidential incumbents rejected the public’s demands for their resignation and democratic transition and sanctioned military violence to maintain the status quo. The public, maintaining their resolve to oust their president from office, rejected power sharing, fearing the deposed leaders would renege on any negotiated agreement in the future (Fearon, 2004). The second contribution of this thesis, albeit not a new discovery, is that the survival of these dictators was critically dependent on military support. In Tunisia and Egypt, the military’s shift of support to the protestors resulted in the sudden fall of Ben Ali and Mubarak from power. In Libya, sanctioned intervention by a UN military coalition resulted in Gaddafi’s elimination, whereas the Syrian military’s support of the regime ensures the continuation of Assad’s presidency. The third contribution of this thesis is that the Assad regime’s use of recombinant authoritarianism—the adaption of its policies following events in its neighbouring Arab countries—has strengthened its prospects for survival.

O NOVO CONSTITUCIONALISMO LATINO AMERICANO E CARL SCHMITT: Um "Diálogo" Entre o Constitucionalismo Nacional e o Constitucionalismo Plurinacional na América Latina para a Construção da ideia de Unidade do Povo
Creators: name: Florindo da Silva, Heleno
Publisher: name: Zenodo
Year: 2023

description: O presente trabalho apontará quais são as principais características do novo constitucionalismo latino americano, bem como exemplos de Estados que passam a adotá-lo e, também, como se deu seu processo de formação, contrapondo a essa nova construção, a ideia clássica de Estado Nacional e, consequentemente, às diretrizes do constitucionalismo clássico, remodelado pelo movimento neoconstitucionalista. Para tanto, utilizaremos as noções de Carl Schmitt acerca da noção de unidade do povo, para analisar como essa unidade deve ser entendida no novo contexto constitucional latino americano. Desse modo, a priori, analisaremos o novo constitucionalismo latino americano, em seguida passaremos para análise das discussões travadas por Carl Schmitt acerca da formação de um sentimento de unidade no povo alemão em sua obra "O Guardião da Constituição", para depois analisarmos, a partir de um diálogo múltiplo dialético, a possibilidade de modificação do paradigma do Estado Nacional para o Plurinacional conformando, assim, a ideia de Estado em nossos dias, ao reconhecimento da diversidade cultural entre os vários povos de uma mesma nação.

Is it possible to formulate least action principle for dissipative systems?

description: A longstanding open question in classical mechanics is to formulate the least action principle for dissipative systems. In this work, we give a general formulation of this principle by considering a whole conservative system including the damped moving body and its environment receiving the dissipated energy. This composite system has the conservative Hamiltonian $H=K_1+V_1+H_2$ where $K_1$ is the kinetic energy of the moving body, $V_1$ its potential energy and $H_2$ the energy of the environment. The Lagrangian can be derived by using the usual Legendre transformation $L=2K_1+2K_2-H$ where $K_2$ is the total kinetic energy of the environment. An equivalent expression of this Lagrangian is $L=K_1-V_1-E_d$ where $E_d$ is the energy dissipated by the friction from the moving body into the environment from the beginning of the motion. The usual variation calculus of least action leads to the correct equation of the damped motion. We also show that this general formulation is a natural consequence of the virtual work principle.

Design and scheduling of agricultural biomass supply chain for a cellulosic ethanol plant
Creators: name: Ebadian, Mahmood
Publisher: name: University of British Columbia
Year: 2013

description: The overall objective of this dissertation is to design and schedule a highly constrained agricultural biomass supply chain to meet the daily biomass demand of a commercial-sized cellulosic ethanol plant at the minimum delivery cost possible. To this end, an integrated simulation/optimization model is developed. The developed simulation model plans and schedules a flow of multi-biomass in the supply chain to meet the daily demand subject to the dynamics and stochasticity of the supply chain. The developed optimization model is used to meet the annual demand at the minimum delivery cost by prescribing the design of the supply chain. The design includes the selection of farms, the location of storage sites, and the assignment of the farms to the storage sites. It also determines the flow of biomass between farms, storage sites and the plant. The integration of the models is made via an iterative procedure. In this procedure, the design is used in the simulation model to manage the flow of biomass in the supply chain. On the other hand, the outputs of the simulation model are used as the inputs of the optimization model to adjust the design. The iterative procedure continues until no improvement can be made in the design. The integrated model is applied to a proposed ethanol plant in Prince Albert, Saskatchewan. The numbers of selected farms and the established storage sites in the integrated model are reduced by 6% and 10%, respectively, compared to the optimization model. Compared to the simulation model, the integrated model leads to the reduction in number of farms (15%), number of storage sites (57%), amount of purchased biomass from farmers (7%), harvested area (13%), supply radius (13%), number of maximum trucks (2 trucks), supply costs (6-12%), energy input (19%), and emitted CO₂ (12%). The results of the sensitivity analysis reveal that the most influential parameter on the design is biomass yield. In addition, bale bulk density and in-field and road transportation operations have the highest impacts on the total supply cost compared to other input parameters.
Costruzione della teologia e unità della ragione in Tommaso d’Aquino.
Una possibile interpretazione del Super Boetium De Trinitate
Creators: name: Bottarini, Giuseppe
Publisher: name: Università degli Studi di Milano
Year: 2008

description: La teologia, come scienza e sapienza, non  asseconda o compie l’ideale di una ragione “forte”, che faccia tutt’uno con la conoscenza speculativa: per una simile ragione – e per la teologia che ne consegue – il significato della realtà, sebbene rivelato, non smette di essere un dato indifferente alla libertà della creatura.

In essa Tommaso esprime   piuttosto la consapevolezza dello scacco cui la ragione va incontro se considera assoluto il criterio soltanto teoretico della verità, dimenticando che il senso dell’essere è piuttosto l’esito possibile di un processo vitale libero, offerto alla  creatura restituita alla propria integrità relazionale. In questa prospettiva, e nel contesto delle discussioni intorno alla scientificità della teologia e all’unità della ragione che si svolgono a Parigi nel corso del XIII secolo, la peculiare costruzione della teologia in Tommaso risulta proposta di un modello relazionale di ragione e di conoscenza, attento alle opportunità ma anche ai rischi propri di un quadro filosofico caratterizzato dall’influenza di Aristotele.

Uno sguardo alla teoria medievale delle obbligazioni
Creators: name: Strobino, Riccardo
Publisher: name: Università degli Studi di Milano
Year: 2008

description: La teoria delle obbligazioni rappresenta un significativo esempio di come un insieme di tecniche logiche possa essere applicato, in maniera feconda, a contesti disputazionali in cui la dimensione dialogica e l’interazione tra soggetti coinvolti in un confronto dialettico hanno un ruolo di primo piano.
  L’attenzione che numerosi studiosi hanno manifestato nei confronti di questa parte della logica modernorum negli ultimi quarat’anni testimonia la profondità e la difficoltà dei problemi teorici che stanno alla base della teoria.
  Molte interpretazioni sono state avanzate circa le motivazioni che spingono i logici medievali a scrivere trattati in cui il portato delle loro dottrine logiche – come, ad esempio, la teoria delle consequentiae - viene declinato ed elaboratamente applicato al gioco dialettico tra due disputanti. La gamma di tali letture comprende differenti ipotesi: la teoria delle obbligazioni potrebbe fornire un nucleo di regole per l’impostazione di un metodo assiomatico rudimentale così come rappresentare un tentativo di elaborare esercizi volti a valutare le capacità logiche degli studenti o, ancora, un gioco teorico, svincolato dall’effettiva applicazione a contesti concreti, la cui finalità sarebbe il mantenimento della coerenza logica.
  E’ stata sostenuta da più interpreti la funzione pedagogica svolta dalla teoria, al di là del fatto che si tratti o meno di un metodo per la conduzione effettiva di dispute reali. Un’altra linea interpretativa collega la teoria delle obbligazioni al contesto della letteratura dei sophismata e degli insolubilia, dal cui repertorio, in effetti, sono spesso tratti molti degli esempi che si incontrano nella lettura dei trattati de obligationibus. In questo senso, la teoria offrirebbe regole e schemi di risposta che un interlocutore deve utilizzare per risolvere o rispondere a enunciati problematici o paradossali. Non si può escludere, inoltre, che nella teoria si realizzi un intreccio delle differenti motivazioni sopra esposte: potrebbe trattarsi di uno strumento che viene sviluppato tanto per la risoluzione di sophismata e insolubilia quanto per indagare il rapporto tra linguaggio e metalinguaggio o altre questioni teoriche. Altri studiosi hanno infine sostenuto  che lo scopo della teoria delle obbligazioni consisterebbe nell’elaborazione di un metodo adatto alla costruzione e alla discussione di esperimenti mentali e che questo costituirebbe una sorta di metametodologia della scienza medievale sulla linea del ragionamento secundum imaginationem.

description: The behaviour of a d-dimensional vectorial N=3 model at a m-axial Lifshitz critical point is investigated by means of a nonperturbative renormalization group approach that is free of the huge technical difficulties that plague the perturbative approaches and limit their computations to the lowest orders. In particular being systematically improvable, our approach allows us to control the convergence of successive approximations and thus to get reliable physical quantities in d=3.
