Subjects: 3-D films--Experimental--Film--Video Art--Installations--Stereoscope

description: This paper represents an historical and cultural context for the research and studio work achieved during the 2 year MAA in Media Arts at ECUAD. The studio component is an exploratory engagement within emerging processes of digital stereoscopic production and alternative uses of new and available tools. The ultimate goal of the research is focused on a process discovering how to work within the stereo space, developing tools for cinematic applications and collecting this knowledge into an arsenal of stereo communication techniques outside of the methods dictated by a dominantly orthostereoscopic understanding of 3D imagery. In order to position the tools, possibilities and subsequent impact of stereoscopic media within current Western culture, the paper reflects upon Jonathan Crary’s concept of the observer and Giorgio Agamben’s apparatus. The apparatus and the observer are concepts that aid in understanding stereo media’s place in history and its re-emergence in the digital present. The studio research project manifests in a stereo film/installation hybrid, which exemplifies the ideas and links between the apparatus and observer. Included in the thesis are descriptions of key influential artists and filmmakers, such as Phillippe Baylaucq, Michael Snow, Wim Wenders, Janet Cardiff and James Turrell. These descriptions are paired with insight into the production and aesthetic qualities of the thesis project to help the reader better understand the scope of applied knowledge gained through the research project, as well as the creative impetus behind it. Alongside the contemporary examples and influences is an historical account of the Spottiswoode Brothers and the pivotal Telecinema festival. The historical account demonstrates how this thesis project and current stereo practitioners are still working to create a stereo language for dimensional films.
Whiteness Is As Whiteness Does: An Examination Of Ideological Whiteness In Art

description: This paper considers how the ideology of Whiteness is reflected in visual art. I examine how my visual practice flows out from my grappling with the contentious ideology of Whiteness. By considering how I may navigate such a discussion, I take two approaches. It is necessary to step back, as much as is possible, to provide critical distance. At the same time I consider my own subjectivity and lived experience as a source of knowledge. These two approaches reinforce the ideas I have chosen to highlight in this paper: interpellation, and embodiment. Additionally, both a clinical approach and lived experience are reflective of two streams of work I have produced throughout the MAA research period. I discuss four projects: dollhouse, The Cleaning Girl and the Boarder, Scope, and Skin Tags. I ground the discussion of these projects with an examination of the ideas of interpellation as discussed by philosophers Louis Althusser and Slavoj Žižek. To support an embodied position I explore the arguments of cultural theorist Sara Ahmed, as well as historians Lorraine Daston and Peter Galison. To provide context for these theories and my work, I also discuss, among others, selected projects by artists William Pope.L, Jenny Saville, Wangechi Mutu, and Izhar Patkin, as well as a collaborative project by Mike Kelley and Paul McCarthy. Several complications are also considered and in particular how the idea of normalcy is connected to the way Whiteness is constructed. These approaches on the ideas of subjectivity, embodied orientation, interpellation, and normalcy frame the discourse on the ideology of Whiteness in this paper.

Efficient and asymptotically optimal kinodynamic motion planning
Creators: name: Littlefield, Zakary
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation explores properties of motion planners that build tree data structures in a robot’s state space. Sampling-based tree planners are especially useful for planning for systems with significant dynamics, due to the inherent forward search that is per- formed. This is in contrast to roadmap planners that require a steering local planner in order to make a graph containing multiple possible paths. This dissertation explores a family of motion planners for systems with significant dynamics, where a steering local planner may be computationally expensive or may not exist. These planners focus on providing practical path quality guarantees without prohibitive computational costs. These planners can be considered successors of each other, in that each sub- sequent algorithm addresses some drawback of its predecessor. The first algorithm, Sparse-RRT, addresses a drawback of the RRT method by considering path quality during the tree construction process. Sparse-RRT is proven to be probabilistically complete under mild conditions for the first time here, albeit with a poor convergence rate. The second algorithm presented, SST, provides probabilistic completeness and asymptotic near-optimality properties that are provable, but at the cost of additional algorithmic overhead. SST is shown to improve the convergence rate compared to Sparse-RRT. The third algorithm, DIRT, incorporates learned lessons from these two algorithms and their shortcomings, incorporates task space heuristics to further improve runtime performance, and simplifies the parameters to more user-friendly ones. DIRT is also shown to be probabilistically complete and asymptotically near-optimal. Application areas explored using this family of algorithms include evaluation of distance functions for planning in belief space, manipulation in cluttered environments, and locomotion planning for an icosahedral tensegrity-based rover prototype that requires a physics engine to simulate its motions.
O(a^2) corrections to the one-loop propagator and bilinears of clover fermions with Symanzik improved gluons

description: We calculate corrections to the fermion propagator and to the Green's functions of all fermion bilinear operators of the form $\barΨΓΨ$, to one-loop in perturbation theory. We employ the Wilson/clover action for fermions and a family of Symanzik improved actions for gluons. The novel aspect of our calculations is that they are carried out to second order in the lattice spacing, $O(a^2)$. Consequently, they have addressed a number of new issues, most notably the appearance of loop integrands with strong IR divergences (convergent only beyond 6 dimensions). Such integrands are not present in $O(a^1)$ improvement calculations; there, IR divergent terms are seen to have the same structure as in the $O(a^0)$ case, by virtue of parity under integration, and they can thus be handled by well-known techniques. We explain how to correctly extract the full $O(a^2)$ dependence; in fact, our method is generalizable to any order in $a$. The $O(a^2)$ corrections to the quark propagator and Green's functions computed in this paper are useful to improve the nonperturbative RI-MOM determination of renormalization constants for quark bilinear operators. Our results depend on a large number of parameters: coupling constant, number of colors, lattice spacing, external momentum, clover parameter, Symanzik coefficients, gauge parameter. To make these results most easily accessible to the reader, we have included them in the distribution package of this paper, as an ASCII file named: Oa2results.m ; the file is best perused as Mathematica input.

A systematic stability analysis of the renormalisation group flow for the normal-superconductor-normal junction of Luttinger liquid wires

description: We study the renormalization group flows of the two terminal conductance of a superconducting junction of two Luttinger liquid wires. We compute the power laws associated with the renormalization group flow around the various fixed points of this system using the generators of the SU(4) group to generate the appropriate parameterization of a S-matrix representing small deviations from a given fixed point S-matrix (obtained earlier in Phys. Rev. B 77, 155418 (2008)), and we then perform a comprehensive stability analysis. In particular, for the non-trivial fixed point which has intermediate values of transmission, reflection, Andreev reflection and crossed Andreev reflection, we show that there are eleven independent directions in which the system can be perturbed, which are relevant or irrelevant, and five directions which are marginal. We obtain power laws associated with these relevant and irrelevant perturbations. Unlike the case of the two-wire charge-conserving junction, here we show that there are power laws which are non-linear functions of V(0) and V(2k_{F}) (where V(k) represents the Fourier transform of the inter-electron interaction potential at momentum k). We also obtain the power law dependence of linear response conductance on voltage bias or temperature around this fixed point.

description: Scalable quantum computation in realistic devices requires that precise control can be implemented efficiently in the presence of decoherence and operational errors. We propose a general constructive procedure for designing robust unitary gates on an open quantum system without encoding or measurement overhead. Our results allow for a low-level error correction strategy solely based on Hamiltonian engineering using realistic bounded-strength controls and may substantially reduce implementation requirements for fault-tolerant quantum computing architectures.

Indeterminacy in Language and Art

Subjects: Indeterminacy (Linguistics)--Language Philosophy--Translating and interpreting--Art -- Philosophy

description: Indeterminacy, triangulation, and translation are often contributing factors to the experience and understanding of a work of art in which meaning can be multi-layered, shifting or malleable. In this thesis, I explore these concepts, both in relation to my art practice and within a historical and cultural context. In essence, these theoretical discussions describe the instantiation of a philosophical idea in a visual art practice. In this way, the thesis can be generally understood as an exploration in the area of the philosophy of language, looking to its application as an impetus for creating visual art, and as an explanatory device for visual art. There are three key philosophers whose ideas are instantiated in my art practice – W.V.O. Quine, Ludwig Wittgenstein, and Donald Davidson. Quine offers the theory of radical translation, which is the translation from an unknown language to a known language, without aid or precedent. Wittgenstein offers the concept of indeterminacy of language, which asserts that multiple meanings for a singular item may be correct. Davidson offers the theory of triangulation, in which a combination of the beliefs and intentions of the artist and of the viewer, each triangulate with the work of art, to make meaning. I discuss three artists whose work has been an inspiration – Joseph Kosuth, Sarah Lucas, and Ann Hamilton. The way these artists use language, humour, and code relates to indeterminacy, reception, and obfuscation. The goal of this essay is to explore the relations between art and philosophy, as a means to develop critical reflection on the methodologies underpinning my own art practice.

description: This paper examines bodily presence and absence, points of connectivity, and negotiates the terrain of the body through two distinct projects. Engaging in a drawing-centered practice I consider embodiment through two projects (Under the Skin and Beyond the Skin), forming a dyad through which to negotiate and illuminate various bodily expressions and representations. Throughout a lived existence, the body undergoes various transformations and adaptations; its ongoing mutation requires a continuous realignment and re-examination. A phenomenological approach acknowledges that an embodied experience is one which is physically aware and shapes our understanding of the world. Trauma, in varying degrees, forces the body to transform and adapt, potentially resulting in a different embodied perspective. Under the Skin takes up a study of embodiment through trauma and the body in pain. Beyond the Skin engages the prosthesis from an artistic perspective, exploring the capacity for altering the figuration of the body, which in turn informs my artistic praxis. Engaging works by artists Rebecca Horn and Matthew Barney, my intention is to develop a context for my own practice and an expansive understanding of prosthetic terminology and the presence of a prosthetic metaphor in artistic practices. As a creative endeavour the refiguration of prosthetic terminology has the potential to enhance the cultural experience of loss, trauma and adversity, allowing an exploration of the body as adaptable and expandable.

description: Superconducting FeSe has been investigated by measurements of the magnetic susceptibility versus temperature and Moessbauer spectroscopy at various temperatures including strong external magnetic fields applied to the absorber. It was found that isomer shift exhibits sharply defined increase at about 105 K leading to the lowering of the electron density on iron nucleus by 0.02 electron/a.u.^3. Above jump in the electron density is correlated with the transition from the P4/nmm to the Cmma structure, while decreasing temperature. Moessbauer measurements in the external magnetic field and for temperatures below transition to the superconducting state revealed null magnetic moment on iron atoms. Hence, the compound exhibits either Pauli paramagnetism or diamagnetic behavior. The principal component of the electric field gradient on the iron nucleus was found as negative on the iron site.

Looking at Word Finding, a Practice-Based Research Project About Participatory and Dialogical Art Processes

Subjects: Artists and community--Communication in art--Interactive art--Video Art

description: The art-based thesis project, Word Finding, is currently being produced through dialogue and conversation. Beginning with a community process and finally being realized in an art context, Word Finding asks larger questions about authorship and public discourse. This work and others described here challenge the reliance on fixed authorship in the way Foucault imagined a future marked by distributed authorship. In Word Finding authorship is continually distributed amongst the work’s participants and audience. This project builds on my earlier art practice where I investigated the way words spoken within a social context produced instability of meaning –how they were interpreted, retold and translated between people. To contextualize this project and my practice in general, I present case studies that provide a variety of models for dialogical art strategies. Linda Duvall and Kutluğ Ataman have produced artworks in which the respatialization of unscripted talking in aesthetic contexts enables a level of audience engagement. Methodologies surrounding dialogical and participatory art forms are discussed here with respect to key texts by Mikhail Bakhtin, Grant Kester, Claire Bishop and others. As an art project, Word Finding investigates the integration of communitybased dialogue and aesthetic use of dialogue within art contexts.

description: This thesis investigates issues of representation from multiple perspectives, but particularly those of the self and other as occurring in the West and in Saudi cultures. It also critically reflects on the methodology, conceptual thinking and artistic process of working on the thesis project Let’s Walk To Saudi. Popular cultural media and the role it plays in creating and perpetuating stereotypes was the initial motivation behind the thesis and was central to the media-based project. Artists and practitioners have begun to investigate similar issues within the context of art production using social media as a form of participatory art practice. An analysis of comparative art projects are included in the examples that contextualize Let’s Walk To Saudi. Let’s Walk To Saudi is a project that established an online community platform on Facebook enabling Saudi students around the world—there are more than 80,000 internationally—to share unedited stories about their experiences abroad, and receive feedback from others in the form of writings, photos, audio, and video clips. The project began by inviting Saudi students studying abroad to represent themselves, challenge themselves to face their fears, rethink cultural boundaries, and question their own preconceptions towards others, while also considering the others’ (Westerners’) preconceptions about Arabs and Muslims. The thesis explores cultural, political and social forms of representation and self-representation between home and abroad. By using social media, the project explores and encourages better communication, increases awareness about individuals from other cultures, and ultimately sets out to challenge stereotypes.

title: #defiltered: Examining Instapoetry through the lens of literary naturalism
Creators: name: Knox, JuEunhae Ruth
Publisher: name: University of Glasgow
Year: 2021

description: Currently 279,489,441 posts strong, the hashtag #nofilter belies Instagram’s infamy for filtered teenage selfies and embodies users’ increasing consciousness of their inauthenticity, especially among post-millennials daily exhibiting digitally manipulated identities. The extremely visual short-form genre of Instapoetry, boasting 14.7 million posts to #poetsofinstagram alone, represents this acute form of consumer unease, yet this so-called “fidget-spinner” literature has received little academic attention. While some magazines have featured the well-known Rupi Kaur, no academic work to date has extensively analysed the aesthetics and poetics of Instapoetry, nor the cultural antecedents that have contributed to its development. This thesis therefore aims to examine a new oeuvre of digital literature by analysing its inheritance of rationalisation, which especially grew in the industrialisation of image and text during the early 20th century. In particular, I will juxtapose popular Instapoetry trends with longstanding motivations and practices of literary naturalists. While writers such as Jack London, Edith Wharton, Theodore Dreiser, and others are certainly separated from contemporary Instapoets by several decades, the naturalists similarly emerged during an increased shift toward a highly visual consumer culture. Their simultaneous participation in and resistance to the market forces that threatened their authorial autonomy, in the midst of public demand for rapidly manufactured, sensational texts, provides a helpful lens for examining contemporary Instapoetry practices. Paralleling the two genres’ similarities and distinctions in seeking monetary success and literary relevance, while manoeuvring within the creative economy, allows us to then grasp the potential for heteronomy or amelioration, effected by this most recent form of “authentic” and “accessible” digital self-expression.

description: We study the tunneling magneto-transport properties of the Ferromagnetic Insulator-Normal Insulator-Ferromagnetic Insulator(F$\mid$N$\mid$F) and Ferromagnetic Insulator-Barrier Insulator-Ferromagnetic Insulator (F$\mid$B$\mid$F) junctions on the surface of topological insulator in which in-plane magnetization directions of both ferromagnetic sides can be parallel and antiparallel. We derive analytical expressions for electronic conductances of the two mentioned junctions with both parallel and antiparallel directions of magnetization and using them calculate magnetoresistance of the two junctions. We use thin barrier approximation for investigating the F$\mid$B$\mid$F junction. We find that although magnetoresistance of the F$\mid$N$\mid$F and F$\mid$B$\mid$F junctions are tunable by changing the strength of magnetization texture, they show different behaviors with variation of magnetization. In contrast to the magnetoresistance of F$\mid$N$\mid$F, magnetoresistance of F$\mid$B$\mid$F junctions shows very smooth enhance by increasing the strength of magnetization. We suggest an experimental set up to detect our predicted effects.

title: Mathematical Modelling of Cross-protection Between Respiratory Viruses.
Creators: name: Waterlow, NR
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2022

description: Respiratory viruses cause substantial health and economic burdens. These viruses circulate concurrently, and changes in host susceptibility brought about by infection by one virus has the potential to change the transmission dynamics of another. Understanding the effects of such cross-protection between viruses at a population level can inform public health policies. Current evidence for cross-protection between these viruses mainly comes from population level shifts in dynamics, which cannot assess causation, and from small-scale biological experiments. I use mathematical modelling to research cross-protection between respiratory viruses, as these methods allow for testing of the mechanism. Initially, I develop a two-pathogen interaction model parameterised to simulate influenza and RSV epidemiology in the UK. Using a surveillance-like stochastic observation process I generate a range of possible trajectories, and then back-infer the parameters using Markov Chain Monte Carlo. I found that the strength and duration of influenza and RSV interaction could be estimated well; however, the robustness of inference does decline towards the extremes of the plausible parameter ranges, with misleading results. Next, I use parallel tempering to fit an adapted two-pathogen model to a unique dataset from Vietnam. I show that the population level-dynamics of influenza and RSV circulation support either moderate or no cross-protection. However, I add evidence that co-infection increases the rate of reporting. The benefits of limiting severe co-infection by vaccination in this setting may therefore outweigh the increased transmission that occurs due to cross-protection between the viruses. Finally, I use coronavirus surveillance data from England and Wales to estimate key seasonal coronavirus (HCoV) parameters, and I use these estimates to investigate age-specific susceptibility to SARS-CoV-2, varying the interaction assumption. I show that while cross-protection between HCoV and SARS-CoV-2 may contribute to the age distribution, it is insufficient to explain the observed reduced susceptibility of children. Collectively, the research in this thesis demonstrates that surveillance data and mathematical models can be used to study respiratory viral interactions. It implies that while models can be used to study this phenomenon, stochasticity can obscure results. The research also alleviates concerns that vaccination against influenza or RSV may have a detrimental impact on the other virus, due to interaction, although this must be investigated further to understand the generalisability of the results to other settings. Finally, the research implies that other factors must influence susceptibility to coronaviruses, and the observed shifting of epidemic peaks that has been hypothesised to be a result of respiratory viral interaction.

description: Two distinct types of magnetoresistance oscillations are observed in two electronic Fabry-Perot interferometers of different sizes in the integer quantum Hall regime. Measuring these oscillations as a function of magnetic field and gate voltages, we observe three signatures that distinguish the two types. The oscillations observed in a 2.0 square micron device are understood to arise from the Coulomb blockade mechanism, and those observed in an 18 square micron device from the Aharonov-Bohm mechanism. This work clarifies, provides ways to distinguish, and demonstrates control over, these distinct physical origins of resistance oscillations seen in electronic Fabry-Perot interferometers.

description: Digital media technologies are shaping the experience of public space. This is even more true as systems evolve that can sense and react to what is happening around them. With this informational reshaping of our urban environment, designers are called on to critically engage and create legible moments in the multiple fluid realities of our cities. This thesis project explores the role that design interventions might have in revealing the plasticity of the built environment and public space. The messages that are projected in public space are made up of content that is shaped by its surroundings, that is to say the reception of a given message is dependent not only on the media or story for its legibility, but also on the constantly changing physical context of the space and its characteristics. This thesis project attempts to discover a methodology for evaluating the delivery of content in relation to the changing physical context of its transmission within space.

Unlike the HTS cuprates and 1111-phase oxypnictides, Ba(Fe1-xCox)2As2 showed practically no broadening of the resistive transitions under magnetic fields up to 45 T. The mass anisotropy gamma = Hc2ab/Hc2c deduced from the slopes of the upper critical field dHc2ab/dT = 4.9T/K and dHc2c/dT = 2.5T/K decreases from ~2 near Tc, to ~1.5 at lower temperatures. We observed the irreversibility field close to Hc2, and a rather unusual symmetric volume pinning force curve Fp(H) suggestive of strong pinning nano-structure.

description: This research project explores family history, craft materials, and how Aboriginal women create meaning in the making of complex and beautiful functional objects such as Pow-wow regalia and quilts. I reference the history and evolution of regalia, beadwork and Aboriginal quilts as a means of examining hybridity as it relates to material and cultural forms. As part of my methodology, hybridity and authenticity will be discussed in relation to Homi Bhaba, James Clifford and Robert Young. Brian Jungen's use of mass-produced commodities in his work and Faith Ringgold's “story quilts” are examined in the context of my material practice. I examine Lori Blondeau and Sherman Alexie's critical use of humour and pop culture to explore Aboriginal self-identity. Feminist examinations of textile practices are related to quiltmaking and handicrafts. My own experience of motherhood and its impact on my art practice is detailed. Drawing from archival research and oral histories my own family history is threaded throughout the thesis as I recover lost histories and knowledge.

Subjects: China--Folklore--Ethnology--History--Myth

description: This thesis project, Chinarians, proposes that our understanding and perceptions of the past are more influential than any actual “historical” events. For this studio thesis project, I am studying a mythical ancient culture: the Chinarians. The Chinarian culture was loosely influenced by the Huns, a tribe of nomads that emerged from ancient China and whose descendents are said to be Hungarians and Turks. Chinarians is visually manifested through the construction of relics, replicas, and reenactments. The project is an investigation into issues of hybridity, and explores the intricacies of cultural representation in the solidification of knowledge types such as historical documentation and ethnography. In this paper, I examine the key methodologies that Chinarians draws from: history, myth, ethnography and reenactment, all of which intersect in my work. These methodologies will include the exploration of both material artifacts, in the form of relics, replicas, and reconstructions, and mythopoeia. In each section, I will elucidate the methodologies by providing an artist or writer as an example.
Extremely energetic Fermi Gamma-Ray Bursts obey spectral energy correlations

description: The extremely energetic Fermi GRBs 080916C, with its Eiso of ~ 10^{55} erg in 1 keV - 10 GeV and intense GeV emission, and 090323 give us a unique opportunity to test the reliability and extension of spectral energy correlations. Based on Konus/WIND and Fermi spectral measurements, we find that both events are fully consistent with the updated (95 events as of April 2009) Ep,i - Eiso correlation, thus further confirming and extending it and pointing against a possible flattening or increased dispersion at very high energies. This also suggests that the physics behind the emission of peculiarly bright and hard GRBs is the same as for softer and weaker ones. In addition, we find that the normalization of the correlation obtained by considering these two GRBs and the other long ones for which Ep,i was measured with high accuracy by the Fermi/GBM are fully consistent with those obtained by other instruments (e.g., BeppoSAX, Swift, Konus-WIND), thus indicating that the correlation is not affected significantly by detectors limited thresholds and energy bands. Prompted by the extension of the spectrum of GRB 080916C up to several GeVs without any excess or cut-off, we also investigated if the evaluation of Eiso in the commonly adopted 1 keV - 10 MeV energy band may bias the Ep,i - Eiso correlation contributing to its scatter. By computing Eiso from 1 keV to 10 GeV, the slope of the correlation becomes slightly flatter, while its dispersion does not change significantly. Finally, we find that GRB 080916C is also consistent with most of the other spectral energy correlations derived from it, with the possible exception of the Ep,i - Eiso - tb correlation.

description: In this study, I investigate the application of active learning approaches, with the help of call and mall frameworks. These interactive learning solutions emphasize learner-created content, with the goal of improving the vocabulary development of grade 7 students. It is assumed that the use of computer and mobile technologies can increase the capacity for learning vocabulary. With a concept prototype, that demonstrates the translation of a textually based Language Arts lesson plan into a visual paradigm for active learning, I create a more porous and malleable language learning model for the Google Generation. My hypothesis is that this prototype will benefit the learning of Language Arts for 7th grade students. Such an instrument could ultimately provide students with the opportunity to engage in knowledge creation and sharing across formal and informal learning environments. The methodology used for this thesis essay begins with defining a problem by utilising both academic and qualitative studies. This is followed by the collecting of evidence from alternative learning approaches, which are defined by their various strengths and deficiencies through product analysis, case studies and theoretical grounds. The essay concludes with a proposed design and concept prototype testing, which I have called The Language Learning Activity Paradigm (llap).

Computer games

description: This thesis details a design process that generates a synthesis between active-driven game-play and dialogue within a computer role playing game (RPG). I intend to generate a process where the player co-evolves with the narrative aspect of an RPG to increase his opportunity to engage and effect the narrative of the game experience. By introducing design methodologies into a game development context, I created adaptive tools through participatory design methods in order to better understand and alleviate points of negative friction during game-play in an RPG. My goal is to facilitate a smoother and more immersive game experience by combining game-play and dialogue together, with both spaces governed by the same cause-and-effect mechanism.

Speaking Spaces: Phenomenology, Meditation and Pleinairism

Subjects: Phenomenology and art--Meditation--Outdoor painting--Plein air painting

description: This paper is about the practice of painting outdoors in the manner of pleinairism. This activity began for me as an effort to overcome a sense of personal alienation by engaging in an applied empathy with space. In turn, the thesis also touches on the general social condition of Postmodern alienation as a context for plein air painting. And it briefly outlines the history of pleinairism, as a methodology that aspired to render the world as it appeared to the contemporaneous eye. My current approach to plein air painting is described as an embodied conversation with space through the index of paint and suggests that in the state of attention, the space and the painter become intertwined in a reciprocal exchange, or a Chiasm as described by Maurice Merleau-Ponty. By painting this way, it is suggested that space and the painter express one another and in so doing, produce an animate document of a painted conversation. This material practice is inspired by phenomenology, meditation and the sensorial experience of working outdoors. This paper seeks to redefine plein air landscape painting for the 21st century as a model for awareness of ourselves and our relationship to space. It describes a methodology of applied empathy, and forgetting the self and predetermined ideas, in order to become receptive to the agency of space.

description: We demonstrate the power of a recently-proposed approximation scheme for the non-perturbative renormalization group that gives access to correlation functions over their full momentum range. We solve numerically the leading-order flow equations obtained within this scheme, and compute the two-point functions of the O(N) theories at criticality, in two and three dimensions. Excellent results are obtained for both universal and non-universal quantities at modest numerical cost.

Studying Soft Matter with "Soft" Potentials: Fast Lattice Monte Carlo Simulations and Corresponding Lattice Self-Consistent Field Calculations

description: The basic idea of fast Monte Carlo (MC) simulations is to perform particle-based MC simulations with the excluded-volume interactions modeled by "soft" repulsive potentials that allow particle overlapping. This gives much faster system relaxation and better sampling of the configurational space than conventional molecular simulations with "hard" repulsions that prevent particle overlapping. Here we present fast lattice MC (FLMC) simulations for confined homopolymers, where multiple occupancy of lattice sites is allowed with a proper Boltzmann weight and thus the evaluation of nearest-neighbor interactions can also be avoided. When compared with the corresponding lattice field theories based on the \emph{same} Hamiltonian, FLMC simulations further provide a powerful means for unambiguously and quantitatively revealing the correlation/fluctuation effects.

description: We study concentrated binary colloidal suspensions, a model system which has a glass transition as the volume fraction $ϕ$ of particles is increased. We use confocal microscopy to directly observe particle motion within dense samples with $ϕ$ ranging from 0.4 to 0.7. Our binary mixtures have a particle diameter ratio $d_S/d_L=1/1.3$ and particle number ratio $N_S/N_L=1.56$, which are chosen to inhibit crystallization and enable long-time observations. Near the glass transition we find that particle dynamics are heterogeneous in both space and time. The most mobile particles occur in spatially localized groups. The length scales characterizing these mobile regions grow slightly as the glass transition is approached, with the largest length scales seen being $\sim 4$ small particle diameters. We also study temporal fluctuations using the dynamic susceptibility $χ_4$, and find that the fluctuations grow as the glass transition is approached. Analysis of both spatial and temporal dynamical heterogeneity show that the smaller species play an important role in facilitating particle rearrangements. The glass transition in our sample occurs at $ϕ_g \approx 0.58$, with characteristic signs of aging observed for all samples with $ϕ>ϕ_g$.

description: Relic abundance of dark matter is investigated in the framework of universal extra dimension (UED) models with right-handed neutrinos. These models are free from the KK graviton problem in the minimal UED model. The first KK particle of the right-handed neutrino is a dark matter candidate in this framework. When ordinary neutrino masses are large enough such as the degenerate mass spectrum case, the dark matter relic abundance can increase significantly. The scale of the extra dimension consistent with cosmological observations can be 500 GeV in the minimal setup of UED models with right-handed neutrinos.

Cosmic Shears Should Not Be Measured In Conventional Ways

description: A long standing problem in weak lensing is about how to construct cosmic shear estimators from galaxy images. Conventional methods average over a single quantity per galaxy to estimate each shear component. We show that any such shear estimators must reduce to a highly nonlinear form when the galaxy image is described by three parameters (pure ellipse), even in the absence of the point spread function (PSF). In the presence of the PSF, we argue that this class of shear estimators do not likely exist. Alternatively, we propose a new way of measuring the cosmic shear: instead of averaging over a single value from each galaxy, we average over two numbers, and then take the ratio to estimate the shear component. In particular, the two numbers correspond to the numerator and denominators which generate the quadrupole moments of the galaxy image in Fourier space, as proposed in Zhang (2008). This yields a statistically unbiased estimate of the shear component. Consequently, measurements of the n-point spatial correlations of the shear fields should also be modified: one needs to take the ratio of two correlation functions to get the desired, unbiased shear correlation.
description: 13 pages, MNRAS in press. The title has been changed from "Ideal Cosmic Shear Estimators Do Not Exist" to the current one. Instead of showing that conventional/ideal shear estimators do not exist in the presence of PSF, we show in the current version that conventional shear estimators do not exist in convenient forms
