description: This paper introduces and studies the notion of output-input stability, which represents a variant of the minimum-phase property for general smooth nonlinear control systems. The definition of output-input stability does not rely on a particular choice of coordinates in which the system takes a normal form or on the computation of zero dynamics. In the spirit of the ``input-to-state stability'' philosophy, it requires the state and the input of the system to be bounded by a suitable function of the output and derivatives of the output, modulo a decaying term depending on initial conditions. The class of output-input stable systems thus defined includes all affine systems in global normal form whose internal dynamics are input-to-state stable and also all left-invertible linear systems whose transmission zeros have negative real parts. As an application, we explain how the new concept enables one to develop a natural extension to nonlinear systems of a basic result from linear adaptive control.

description: This dissertation explores the historical representation of the Italian nation in regard to the narration of the Libyan War and its causes and implications in the consolidation of both state and society. The texts I examine were all published in contemporary newspapers and magazines, which span from 1910 to 1912, as they refer to events throughout the war. The facts involved in and that led to the war created the first important organic affiliation between politics, finance, mass-society and mass media. I will argue that through the literary narration of this war, Italians came to terms with problematic and unresolved issues of national identity while concurrently confirming the embodied gender configurations along with the relation of the state's power over citizens to their claims of national participation. Chapter I frames the Libyan war from a political, social and economic point of view. It investigates how war was used to stimulate the Italian new capitalistic economy while balancing the new industrial concentration of power and the mass demand of welfare and participation. Chapter II elucidates the moralistic and epistemological dimensions of the rhetoric of violence, which leads to an understanding of how the war was used to regulate and produce a collective national organism. Chapter III provides the foundation for a reflection on how men and masculinity were 'constructed' authorities and guarantor within the traditional patriarchal society and the new capitalistic system. The final chapter, then, focuses on how women reshaped their role (the crocerossina's explicit sexuality subverted a superimposed homosocial order) while still placing themselves under the hegemonic control of men. My analysis traces the figure of the mother as the driving force in the creation of this new nation. Italy's attempt to cultivate a strong nation-state instead catalyzed the formation of the fascist regime.

description: We consider a nearly-AdS$_2$ gravity theory on the two-sided wormhole geometry. We construct three gauge-invariant operators in NAdS which move bulk matter relative to the dynamical boundaries. In a two-sided system, these operators satisfy an SL(2) algebra (up to non-perturbative corrections). In a semiclassical limit, these generators act like SL(2) transformations of the boundary time, or conformal symmetries of the two sided boundary theory. These can be used to define an operator-state mapping. A particular large N and low temperature limit of the SYK model has precisely the same structure, and this construction of the exact generators also applies. We also discuss approximate, but simpler, constructions of the generators in the SYK model. These are closely related to the "size" operator and are connected to the maximal chaos behavior captured by out of time order correlators.

Illuminating Art: A Philosophical Perspective on Students’ and Teachers’ Work in Art Education
Creators: Marini, Guillermo Jorge
Publisher: name: Columbia University
Year: 2012
Subjects: Education--Philosophy
Art--Study and teaching

description: This dissertation inquires about the situation of the arts in education by suggesting an alternative perspective on the way we see art. It does so through the illumination of three distinct yet complementary ways. First, this study explores what a primordial sense of art would look like. I argue that we can understand art as a knowing-making disposition where wondering with the artwork and relating with its inherent elements becomes one and the same activity. Second, this investigation proposes the notion of respiration as a lens that allows seeing art as a fact that assumes and surpasses similar and contrary interpretations of the artwork' meanings. Finally, this research proposes the notion of exercise in possibility as a way to further expand what art can look like in education. I claim that by developing resemblances of human life, art can operate as a standard of possibility. After characterizing each of these notions, I move on to refine their practical implications for students' and teachers' tasks.
Field theoretic renormalization group for a nonlinear diffusion equation

Year: 2002
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: The paper is an attempt to relate two vast areas of the applicability of the renormalization group (RG): field theoretic models and partial differential equations. It is shown that the Green function of a nonlinear diffusion equation can be viewed as a correlation function in a field-theoretic model with an ultralocal term, concentrated at a spacetime point. This field theory is shown to be multiplicatively renormalizable, so that the RG equations can be derived in a standard fashion, and the RG functions (the $β$ function and anomalous dimensions) can be calculated within a controlled approximation. A direct calculation carried out in the two-loop approximation for the nonlinearity of the form $ϕ^α$, where $α>1$ is not necessarily integer, confirms the validity and self-consistency of the approach. The explicit self-similar solution is obtained for the infrared asymptotic region, with exactly known exponents; its range of validity and relationship to previous treatments are briefly discussed.

Laplace transformations of hydrodynamic type systems in Riemann invariants: periodic sequences
Creators: name: Ferapontov, E. V.
Publisher: name: arXiv
Year: 1997
Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: The conserved densities of hydrodynamic type system in Riemann invariants satisfy a system of linear second order partial differential equations. For linear systems of this type Darboux introduced Laplace transformations, generalising the classical transformations in the scalar case. It is demonstrated that Laplace transformations can be pulled back to the transformations of the corresponding hydrodynamic type systems. We discuss periodic Laplace sequences of with the emphasize on the simplest nontrivial case of period 2. For 3-component systems in Riemann invariants a complete discription of closed quadruples is proposed. They turn to be related to a special quadratic reduction of the (2+1)-dimensional 3-wave system which can be reduced to a triple of pairwize commuting Monge-Ampere equations. In terms of the Lame and rotation coefficients Laplace transformations have a natural interpretation as the symmetries of the Dirac operator, associated with the (2+1)-dimensional n-wave system. The 2-component Laplace transformations can be interpreted also as the symmetries of the (2+1)-dimensional integrable equations of Davey-Stewartson type. Laplace transformations of hydrodynamic type systems originate from a canonical geometric correspondence between systems of conservation laws and line congruences in projective space.

description: All technology instruments use electrical and electronic systems that, before their production, need to be verified via simulation software. A new simulation software called DSPICE (Designing Circuits and Simulation by SPICE) has been programmed. As presented in this paper, the main objective of this software is to simplify the modeling of analog elements and circuits to describe design schematics involving libraries, packages, and symbols. DSPICE would be a free software (GNU license). The circuit simulation in DSPICE allows a detailed frequency-domain analysis, DC analysis, and time-domain analysis. The output signals are acquired in different operating points and they are displayed by means of a dedicated waveform editor. The behavioral modeling of analog elements and the simulations results of different test circuits are reported in the text

description: We investigate the phenomenon of the decay of a supercurrent due to the zero-temperature quantum tunneling of vortices from the edge in a thin superconducting film in the absence of an external magnetic field. An explicit formula is derived for the tunneling rate of vortices, which are subject to the Magnus force induced by the supercurrent, through the Coulomb-like potential barrier binding them to the film's edge. Our approach ensues from the non-relativistic version of a Schwinger-type calculation for the decay of the 2D vacuum previously employed for describing vortex-antivortex pair-nucleation in the bulk of the sample. In the dissipation-dominated limit, our explicit edge-tunneling formula yields numerical estimates which are compared with those obtained for bulk-nucleation to show that both mechanisms are possible for the decay of a supercurrent.

description: Frustrated magnets can host numerous exotic many-body quantum and topological phenomena. GeNi$_2$O$_4$ is a three dimensional $S=1$ frustrated magnet with an unusual two-stage transition to the two-dimensional antiferromagnetic ground state, while GeCu$_2$O$_4$ is a high-pressure phase with a strongly tetragonally elongated spinel structure and magnetic lattice formed by $S=1/2$ CuO$_2$ linear chains with frustrated exchange interactions and exotic magnetic behavior. Here we report on the first thin-film epitaxial stabilization of these two compounds. Developed growth mode, surface morphology, crystal structure and copper valence state were characterized by in-situ reflection high-energy electron diffraction, atomic force microscopy, X-ray reflectivity, X-ray diffraction, X-ray photoelectron spectroscopy and resonant X-ray absorption spectroscopy. Our results pave an alternative route to the comprehensive investigation of the puzzling magnetic properties of these compounds and exploration of novel emergent features driven by strain.

description: Dendrimers represent a class of polymers characterized by a highly branched architecture, precise composition, and a multitude of functional groups, garnering significant interest in biomedical applications. These are three-dimensional nanostructures characterized by a high degree of molecular homogeneity, adjustable size, multivalence, significant surface functionality, and high aqueous solubility. Dendrimers, owing to their significant properties, are currently utilized for drug delivery and are under investigation as potential carriers for nucleic acid-based vaccines. Nucleic acid, as a therapeutic molecule, offers several advantages, including safety, efficacy, and cost-effectiveness. These delivery systems may exhibit accelerated development timelines, reduced production costs, and enhanced storage and transportation efficiency. An essential aspect of DNA or RNA delivery technology is the selection of an efficient method of delivery. This review summarizes the classification, preparation, and formulation strategies for dendrimer delivery. Furthermore, the delivery of RNA via dendrimers for a range of disease conditions, including cancer, autoimmune disorders, infectious diseases, neurological disorders, and metabolic disorders, has been investigated and summarized.
Rates of sulfide oxidation in submerged environments : implications for subaqueous disposal
Creators: name: Morin, Kevin A. (Kevin Andrew), 1955-
Publisher: name: The University of British Columbia
Year: 2009

description: The placement of sulfide-bearing tailings and rock in submerged environments has long been recognized as a primary technique for control of acid drainage, and recent field investigations provide further evidence of its success. However, subaqueous disposal does not automatically ensure that acid generation is completely halted. In fact, there are reasons why acid generation might not cease in a submerged environment. Recent experimental data from a generic experiment and from the proposed Cinola Gold Project are reviewed to (1) obtain rates of pyrite oxidation under submerged conditions and (2) show that ferric iron apparently does not oxidize pyrite in the absence of dissolved oxygen. The rates are then used to estimate consumption of dissolved oxygen along groundwater flowpaths and to determine a first-order-rate relationship between reaction rate and dissolved oxygen for calculations of dissolved-oxygen diffusion. Three relatively simple examples show how to apply the concepts and equations. One example for oxygen diffusion shows that, for constant values of porosity and pyrite content, tailings will generate more acidity than coarse rock because of the steeper oxygen gradients within the tailings. The major conclusions drawn from this work are that site-specific conditions dominate in determining the eventual water chemistry and that environmental (hydrogeological) conditions of the disposal site should be well defined. In this way, the site-specific rates and concentrations can be determined and, if necessary, details of the subaqueous disposal can be refined for optimum performance.

description: The field theoretic renormalization group is applied to the stochastic Navier--Stokes equation that describes fully developed fluid turbulence. The complete two-loop calculation of the renormalization constant, the $β$ function, the fixed point and the ultraviolet correction exponent is performed. The Kolmogorov constant and the inertial-range skewness factor, derived to second order of the $\eps$ expansion, are in a good agreement with the experiment. The possibility of the extrapolation of the $\eps$ expansion beyond the threshold where the sweeping effects become important is demonstrated on the example of a Galilean-invariant quantity, the equal-time pair correlation function of the velocity field. The extension to the $d$-dimensional case is briefly discussed.

description: Questo contributo descrive la correlazione tra didattica dell’italiano e politica linguistica nella comunità italiana stanziata in Canada a partire da due casi di studio, il Centro Scuola italiano, finanziato dal Ministero per gli Affari Esteri e la Cooperazione Internazionale (MAECI), e l’Istituto Italiano di Cultura. I dati sono stati raccolti tramite interviste a testimoni esperti e tramite questionari per gli apprendenti tra il 2016 e il 2018. I risultati dello studio evidenziano profonde differenze tra i due contesti indagati, differenze che riguardano il tipo di platea di apprendenti, la competenza dell’italiano, le modalità di erogazione dei corsi. In tale prospettiva, emerge la necessità di una politica linguistica che sappia rivolgersi alle tante platee di apprendenti che si avvicinano, per motivazioni diverse, allo studio dell’italiano.

description: A bottleneck can largely deteriorate the flow, such as a traffic light or an on-ramp at a road. To alleviate bottleneck situations, one of the important strategies is to control the input rate to suit the state of the road. In this study, we propose an effective velocity control of traveling particles, in which the particle velocity depends on the state of a bottleneck. To analyze our method, we modify the totally asymmetric simple exclusion process (TASEP) and introduce a slow-to-start rule, which we refer to as controlled TASEP in the present paper. Flow improvement is verified in numerical simulations and theoretical analyses by using controlled TASEP.

description: Conservation agriculture is promoted as a green technology that enhances the productivity and food security of farmers. However, there is limited evidence from practising farmers regarding these expected outcomes. This study evaluates the impact of conservation agriculture on the productivity of maize and food security outcomes among smallholder farmers in Zimbabwe. The propensity score-matching approach was used to estimate the impact. The data is based on a 2013 survey of 488 households. Conservation agriculture, largely defined by the use of planting basins, had a positive and significant (p < 0.05) impact on maize grain yield (ATT = 473 kgha-1), with the magnitude more pronounced among female-headed households (ATT = 515.53 kgha-1). The increased grain production extended the households’ grain self-provision period by 1.14 months for the pooled sample, and by a slightly longer period of 2.89 months for the female-headed sample. The study concludes that conservation agriculture increases maize productivity and grain supply to households, particularly for female-headed households.

description: In the study of degenerate plasmas contained within compact astrophysical objects, both special relativity and general relativity play important roles. After reviewing the existing treatment in the literature, here we employ the methods of relativistic thermal quantum field theory to compute the equation of states of degenerate matter for compact astrophysical objects such as the white dwarfs and the neutron stars. In particular, we compute the equation of states that include leading order corrections due to the finite temperature, the fine-structure constant as well as the effect of gravitational time dilation. We show that the fine-structure constant correction remains well-defined even in the non-relativistic regime in contrast to the existing treatment in the literature.

description: Optical coherence tomography (OCT) has been emerging as a promising imaging technique, with a strong capability of non-invasive, in vivo, high resolution, depth-resolved imaging. There is a great potential to use OCT to guide the treatment of arrhythmias, to prevent preterm birth, and to detect breast cancer. To facilitate the clinical applications, this thesis presents three image analytic tools to characterize biological tissue: 1) automated fiber direction analysis; 2) automated volumetric stitching; 3) automated tissue classification. The fiber direction analysis consists of a particle-filter-based 3D tractography scheme and a pixel-wise fiber analysis scheme. The stitching algorithm enlarges the field of view of current OCT system from millimeter to centimeter level by volumetric stitching using scale-invariant feature transform. Based on relevance vector machine, a region-based classification scheme and a grid-based classification scheme are developed to automatically identify tissue composition in human cardiac tissue and human breast tissue. These tools are collaboratively used to study OCT images from cardiac, cervical, and breast tissue.
      In cardiac tissue, we apply the fiber orientation analysis to reconstruct 3D cardiac myofibers tractography and perform pixel-wise fiber analysis on the collagen region within human heart. In addition, we apply the region-based algorithm to segment and classify tissue compositions, such as collagen, adipose tissue, fibrotic myocardium, and normal myocardium, over a single or a stitched OCT volume. Using our algorithm, we observe fiber directionality change over depths and find that the fiber orientation changes more dramatically in atria than in ventricle. We also observe different dispersion patterns within collagen layer.
      In cervical tissue, our stitching algorithm enables a paramount 3D view of entire axial slices. Together with pixel-wise fiber orientation scheme, we analyze the difference of dispersion property within inner/outer regions of four quadrants. We observe two dispersion patterns in pregnant and non-pregnant cervical tissue at the location close to upper cervix. In addition, we discover that an increasing trend of dispersion and an increasing trend of penetration depth from internal orifice (os) to external os.
      In breast tissue, we visualize various features in both benign and malignant tissues such as invasive ductal carcinoma (IDC), ductal carcinoma in situ, cyst, and terminal duct lobule unit in stitched OCT images. Focusing on the automated detection of IDC, we propose a hierarchy framework of classification model and apply our classifier in two OCT systems and achieve both reasonable sensitivity and specificity in identifying cancerous region.

description: This paper examines determinants of the adoption of rainwater-harvesting technologies in a rain shadow area of southern Malawi. The most common ex situ technologies in the area were dams, and the widely used in situ technologies were box ridges, contour markers and swales. Adopters treated, on average, 80% of their farms with the rainwater-harvesting technologies, a move that significantly increased their food security status and incomes. The key finding of the study is that the choice of technologies was influenced by land slope and quality, farm size, soil texture, security of land tenure, education level of household head and extension support. The results therefore underscore the potential gains from rainwater-harvesting technologies in improving farmer income and food security, and the need to promote the technologies as a package, because a household may implement different technologies on the same field depending on diverse social, economic, institutional and environmental factors.

description: Microscopic lasers are an emerging platform for biophotonic applications. These lasers are free-standing particles with diameters of hundreds of nanometres to a few micrometres. They generate coherent emission characterised by bright and narrow lasing peaks at unique spectral positions. Particularly in the field of cell biology, such microlasers are an attractive tool for a range of applications, owing to their straightforward integration into living cells. Intracellular microlasers are optically excited and their distinct lasing spectra are recorded using custom spectral imaging systems. These spectra can serve as barcodes for tracking applications, and they can be used as intracellular sensors due to the dependence of the lasing spectra on the optical properties of their immediate environment. Here, a custom imaging system for high-throughput microlaser readout was developed to allow capitalising on the great potential of microlasers for high-throughput measurements with single-cell specificity. This hyperspectral confocal microscope allows automated highspeed 3D-scanning of large volumes, recording a high-resolution spectrum at each voxel. The setup is predominantly used to record spectra from polystyrene microbead lasers and semiconductor nanodisk lasers. The semiconductor materials forming the nanodisk lasers were also improved for integration with the high-throughput microscope and for deep-tissue applications. Following these advances, applications of bio-integrated microlasers were extended to larger and more complex systems, including 3D cell culture models and small animals. Due to the high-speed and high-resolution readout, this has allowed dynamic sensing with multiple microlasers in parallel, which was used for contractility sensing in a cardiac cell culture model. The spectral shifts of the measured lasing peaks were used for quantitative measurements of the local refractive index by developing and employing appropriate mathematical models. Further, the tracking capabilities were demonstrated in a 3D epidermis model, where the cellular migration was followed, and in small marine animals.

description: The spontaneously generated magnetic flux observed by Mannhart et. al. (1996) in 45 degree grain boundaries in YBCO was explained by them in terms of a d-wave superconducting order parameter and grain boundary faceting. This article argues that twin boundaries which contact the grain boundary also play an important role.

description: A colouring of a graph is "nonrepetitive" if for every path of even order, the sequence of colours on the first half of the path is different from the sequence of colours on the second half. We show that planar graphs have nonrepetitive colourings with a bounded number of colours, thus proving a conjecture of Alon, Grytczuk, Haluszczak and Riordan (2002). We also generalise this result for graphs of bounded Euler genus, graphs excluding a fixed minor, and graphs excluding a fixed topological minor.

description: Introduction au numéro 37 de la revue ethnographiques.org L’acte du « retour » au cours d’un voyage implique la recherche d’un lien distendu, parfois rompu, avec une terre et des personnes perçues comme constitutives d’une histoire personnelle ou familiale. Ce dossier met l’accent sur l’expérience même du « voyage retour » et examine la manière dont celui-ci est sous-tendu par une démarche de recherche. Les pratiques de quête constituent un leitmotiv des retrouvailles avec un endroit considéré comme celui des « origines », au cours de déplacements qui sont également qualifiés de « recherches des racines » par les voyageurs. La centralité de la quête, raison d’être de ces voyages, tient à trois éléments qui constituent les axes de réflexion qu’adoptent les articles ici réunis : premièrement, intrinsèque au projet de « retour », la quête est mise en récit et les narrations du voyage sont des narrations de soi ; deuxièmement, elle est ce qui leur donne forme, ce qui modèle le déroulement du voyage, ses séquences temporelles et son déploiement dans l’espace ; et enfin, troisièmement, elle est une mise à l’épreuve de l’appartenance, où se joue une tension entre familiarité et étrangeté.
description: Introduction "Returning” invokes the search for a distended – sometimes broken – connection to places and people that are seen as a constitutive part of personal or family histories. This journal issue focuses on the experience of “return” voyages and examines how they are informed by the idea of the quest. The quest is a central motif framing encounters happening during trips to places imagined as “origins” ; travellers often refer to them as “searching for their roots”. The centrality of the quest resides in three practices that constitute the main topics of the papers in this issue : First, intrinsic to voyages of returning is the practice of narrative, whereby stories of the journey become narratives of the self. Second, the quest shapes the itinerary/rhythm of the trip – its sequences and how it unfolds in time and space. Third, return travel works as a test (épreuve) of belonging ; there is a tension at play between familiarity and estrangement.
Imaging the World: the Literature and Aesthetics of Mori Ogai, the Shirakaba School, and Akutagawa Ryunosuke

description: This dissertation examines the role of aesthetics in Japanese literary discourse, with attention to the emergence of new cross-cultural perspectives, from the late 1880s through the 1920s.  Modernity in Japan was marked by the rapid and often jarring juxtapositions of new techniques and ideas from Western sources against older Japanese traditions, and my project considers how literary authors envisioned and interpreted this cultural eclecticism.  In particular, I focus on their reactions to Western paintings and sculptures.  The visual arts seemed to offer viewers a direct access to `universal' aesthetic values though their non-linguistic nature, and thus appealed to those seeking to attain cosmopolitan perspectives.  Through analyzing Japanese writers' literary responses to foreign artworks, and their ideas on vision as an avenue of information, I investigate the changing nature of representation and signification in this new age, and the role of literary language within it.
      I take as the main subjects of my dissertation Mori Ogai (1862-1922), the members of the Shirakaba School such as Mushanokôji Saneatsu (1885-1976) and Shiga Naoya (1883-1971) during the period of their eponymous publication Shirakaba (1910-1923), and Akutagawa Ryûnosuke (1892-1927).  Each of these authors has been both praised and denigrated for the high-minded idealism and aestheticism of his works, in no small part because of a marked tendency to employ foreign literary and artistic references.  I argue that despite assessments that their works had been composed at an intellectual remove from the social and material contexts in which they lived, the ideal of aesthetics they had upheld as a fixed and transcendental principle that allowed for their appreciation of imported images and ideas of beauty, in fact catalyzed their critical assessments of their own discursive positions within Japanese society.  These writers explored the links and the disjunctions between their artistic ideals--which spanned across disparate cultural and national boundaries--and their more immediate awareness of themselves as citizens of modern Japan.  They discovered that for them, any attempt at cosmopolitanism had to take place within the contexts of their Japanese realities, and any thoughts about it had to be voiced through the medium of Japanese literary language.  Even visual images could not ultimately elide the viewer's conceptual frameworks, and were interpreted in light of them.  What resulted was thus a distinctly hybrid outlook in which their conceptions of Japan, the world, their individual identities, and their creative and critical productions, were indelibly linked with each other.

description: The formaldehyde $\rm H_2CO(1_{10} - 1_{11})$ absorption line and H$110α$ radio recombination line (RRL) have been observed toward the Aquila Molecular Cloud using the Nanshan 25 m telescope operated by the Xinjiang Astronomical Observatory CAS. These first observations of the $\rm H_2CO$ $(1_{10} - 1_{11})$ absorption line determine the extent of the molecular regions that are affected by the ongoing star formation in the Aquila molecular complex and show some of the dynamic properties. The distribution of the excitation temperature $T_{ex}$ for $\rm H_2CO$ identifies the two known star formation regions W40 and Serpens South as well as a smaller new region Serpens 3. The intensity and velocity distributions of $\rm H_2CO$ and $\rm ^{13}CO(1-0)$ do not agree well with each other, which confirms that the $\rm H_2CO$ absorption structure is mostly determined by the excitation of the molecules resulting from the star formation rather than by the availability of molecular material as represented by the distribution. Some velocity-coherent linear $\rm ^{13}CO(1-0)$ structures have been identified in velocity channel maps of $\rm H_2CO$ and it is found that the three star formation regions lie on the intersect points of filaments. The $\rm H110α$ emission is found only at the location of the W40 H II region and spectral profile indicates a redshifted spherical outflow structure in the outskirts of the H II region. Sensitive mapping of $\rm H_2CO$ absorption of the Aquila Complex has correctly identified the locations of star-formation activity in complex molecular clouds and the spectral profiles reveal the dominant velocity components and may identify the presence of outflows.
