0191 The Currency of Gottfried Lindauer’s Māori Portraits
Creators: name: Turner, Stephen
Publisher: name: RIHA Journal
Year: 2018

description: This article addresses the relations between painting, photography and settler colonialism in the nineteenth century through the Māori portraits of Gottfried Lindauer. Lindauer paintings are partly notable for the role that photography, via the projective device of the episcope, played in their production. In the context of the European exoticising of non-western others, and a rapidly expanding market for their images, this intermedial device manifests a gap between painter and sitter, pre-modern and modern, the existing older county of Māori and the new county of New Zealand. The photographic operation of the exotic further includes national and international exhibitions in which Lindauer’s portraits were shown, and the collectors, curators and commissioners of Lindauer’s work, who I conceive as parasitical intermediaries or, in Kwame Anthony Appiah’s phrase, culture brokers. Such figures situate Lindauer’s paintings within a metropolitan regime of evaluation which is underpinned by distance and debt. However, the portraits are also vehicles for currency of another kind, which is the mana motuhake (independent authority) of Māori. Understood within Te Ao Māori (the Māori world) the portraits bridge the perceptual gap of the exotic, and make present, or felt, the historically continuous self-sovereignty of their subjects.

description: Brain is one of the most energy demanding organs in mammals, and its total metabolic rate scales with brain volume raised to a power of around 5/6. This value is significantly higher than the more common exponent 3/4 relating whole body resting metabolism with body mass and several other physiological variables in animals and plants. This article investigates the reasons for brain allometric distinction on a level of its microvessels. Based on collected empirical data it is found that regional cerebral blood flow CBF across gray matter scales with cortical volume $V$ as $CBF \sim V^{-1/6}$, brain capillary diameter increases as $V^{1/12}$, and density of capillary length decreases as $V^{-1/6}$. It is predicted that velocity of capillary blood is almost invariant ($\sim V^ε$), capillary transit time scales as $V^{1/6}$, capillary length increases as $V^{1/6+ε}$, and capillary number as $V^{2/3-ε}$, where $ε$ is typically a small correction for medium and large brains, due to blood viscosity dependence on capillary radius. It is shown that the amount of capillary length and blood flow per cortical neuron are essentially conserved across mammals. These results indicate that geometry and dynamics of global neuro-vascular coupling have a proportionate character. Moreover, cerebral metabolic, hemodynamic, and microvascular variables scale with allometric exponents that are simple multiples of 1/6, rather than 1/4, which suggests that brain metabolism is more similar to the metabolism of aerobic than resting body. Relation of these findings to brain functional imaging studies involving the link between cerebral metabolism and blood flow is also discussed.

description: We report the first two-dimensional mapping of the stellar population and non-stellar continua within the inner 180 pc (radius) of NGC 1068 at a spatial resolution of 8 pc, using integral field spectroscopy in the near-infrared. We have applied the technique of spectral synthesis to data obtained with the instrument NIFS and the adaptive optics module ALTAIR at the Gemini North Telescope. Two episodes of recent star formation are found to dominate the stellar population contribution: the first occurred 300 Myr ago, extending over most of the nuclear region; the second occurred just 30 Myr ago, in a ring-like structure at ~100 pc from the nucleus, where it is coincident with an expanding ring of H2 emission. Inside the ring, where a decrease in the stellar velocity dispersion is observed, the stellar population is dominated by the 300 Myr age component. In the inner 35 pc, the oldest age component (age > 2Gyr) dominates the mass, while the flux is dominated by black-body components with temperatures in the range 700 < T < 800 K which we attribute to the dusty torus. We also find some contribution from black-body and power-law components beyond the nucleus which we attribute to dust emission and scattered light.

description: One of the key predictions of modeling from the IR excess of Herbig Ae stars is that for protoplanetary disks, where significant grain growth and settling has occurred, the dust disk has flattened to the point that it can be partially or largely shadowed by the innermost material at or near the dust sublimation radius. When the self-shadowing has already started, the outer disk is expected to be detected in scattered light only in the exceptional cases that the scale height of the dust disk at the sublimation radius is smaller than usual. High-contrast imaging combined with the IR spectral energy distribution allow us to measure the degree of flattening of the disk, as well as to determine the properties of the outer disk. We present polarimetric differential imaging in $H$ band obtained with Subaru/HiCIAO of one such system, MWC 480. The HiCIAO data were obtained at a historic minimum of the NIR excess. The disk is detected in scattered light from 0\farcs2-1\farcs0 (27.4-137AU). Together with the marginal detection of the disk from 1998 February 24 by HST/NICMOS, our data constrain the opening half angle for the disk to lie between 1.3$\leqθ\leq 2.2^\circ$. When compared with similar measures in CO for the gas disk from the literature, the dust disk subtends only $\sim$30% of the gas disk scale height (H/R$\sim$0.03). Such a dust disk is a factor of 5-7 flatter than transitional disks, which have structural signatures that giant planets have formed.

0195 Theorising Lindauer's Māori Portraits: Rethinking Images of Māori in Museums, Exhibitions, Ethnography and Art
Creators: name: McCarthy, Conal
Publisher: name: RIHA Journal
Year: 2018

description: This paper surveys ‘representations’ of Māori in connection with museums and international exhibitions from 1873-1925, in particular through works of art by painters such as Lindauer and taonga (treasures) made by Māori people themselves. It questions the postmodern analysis of objects and public display in terms of representation, along with the politics of identity that go with it, arguing instead that using a framework of visual culture, actor-network theory and indigenous agency illuminates these objects in a different, and altogether more complex way. In particular it draws on historical Māori accounts of their critical but enthusiastic engagement with western cultures of collection and display, and explores how this evidence might underpin new methods of analysis both in the study of colonial art and its histories and contemporary museum practice.

Publisher: name: RIHA Journal
Year: 2019

description: This article examines the stylistic development of church architecture in the town of Nakhichevan-on-Don, founded in 1779 by Armenians resettled from the Crimea by Catherine II. The study uncovers three main trends in the work of the Armenian church architects: At first, they operated within the context of late eighteenth-/ early nineteenth-century Russian Neoclassicism (Classicism in the terminology of Russian historiography). Then there was a period of conservatism in Armenian architecture in the heyday of Historicism in Russia in the third quarter of the nineteenth century. Thereafter, we witness attempts to revive the national style with methods borrowed from late nineteenth-century Russian architecture. The survey demonstrates how monumental architecture was related to state policy and the poly-ethnic context of the early modern empire. Thus it contributes to a better understanding of the cultural development of national communities in Russia.

description: We discuss the equilibrium properties of dilute Bose gases using a non-perturbative formalism based on auxiliary fields related to the normal and anomalous densities. We show analytically that for a dilute Bose gas of weakly-interacting particles at zero temperature, the leading-order auxiliary field (LOAF) approximation leads to well-known analytical results. Close to the critical point the LOAF predictions are the same as those obtained using an effective field theory in the large-N approximation. We also report analytical approximations for the LOAF results in the unitarity limit, which compare favorably with our numerical results. LOAF predicts that the equation of state for the Bose gas in the unitarity limit is E / (p V) = 1, unlike the case of the Fermi gas when E / (p V) = 3/2.

Study Of The Interaction Between The Solar Wind And The Earth Magnetosphere: Theoretical Model And Application On Data Analysis Of The Halloween Event Of October 2003

Publisher: name: Zenodo

Subjects: Solar Wind, Magnetosphere, Simulation, PIC codes

description: A new approach, using a 3D electromagnetic particle-in-cell (PIC) code, is presented

to study the sensitivity of the Earths magnetosphere to the variability of the solar

wind bulk velocity. Starting with a solar wind impinging upon a magnetized Earth,

time was let to the system so a steady state structure of the magnetosphere was

attained. Then an impulsive disturbance was applied to the system by changing the

bulk velocity of the solar wind to simulate a depression in the solar wind dynamic

pressure, for zero, southward and northward interplanetary magnetic eld (IMF). As

a result of the applied disturbance, an air pocket eect that could be described as a 15

RE wide gap is formed for all cases of IMF condition. As soon as the gap hit the initial

bow shock of the steady magnetosphere, a reconnection between the Earths magnetic

eld and the southward IMF was noticed at the dayside magnetopause (MP). During

the expansion phase of the system, the outer boundary of the dayside magnetopause

broke up in the absence of the IMF, yet it sustained its bullet shape when a southward

and a northern IMF were included. The time relaxation of the MP for the three IMF

cases was studied. The code is then applied to study the Halloween event of October

xvii

2003. Our simulation produced a new kind of air pocket, a rareed space that was

generated following a strong gradient in the impinging IMF. Such a feature is quite

similar to observed hot

ow anomalies and may have the same origin.

A crucial characteristic of these setups is that the excitations generated by the initial perturbation presents non-trivial quantum correlations. As a consequence, for any ti

description: We address electroweak baryogenesis in the context of composite Higgs models, pointing out that modifications to the Higgs and top quark sectors can play an important role in generating the baryon asymmetry. Our main observation is that composite Higgs models that include a light, gauge singlet scalar in the spectrum [as in the model based on the symmetry breaking pattern SO(6)/SO(5)], provide all necessary ingredients for viable baryogenesis. In particular, the singlet leads to a strongly first-order electroweak phase transition and introduces new sources of CP violation in dimension-five operators involving the top quark. We discuss the amount of baryon asymmetry produced and the experimental constraints on the model.

description: We extend the construction of field operators in AdS as smeared single trace operators in the boundary CFT to gauge fields and gravity. Bulk field operators in a fixed gauge can be thought of as non-local gauge invariant observables. Non-local commutators result from the Gauss law constraint, which for gravity implies a perturbative notion of holography. We work out these commutators in a generalized Coulomb gauge and obtain leading order smearing functions in radial gauge.
Ginzburg-Landau Like Theory for High Temperature Superconductivity in the Cuprates: Emergent d-wave Order

description: High temperature superconductivity in the cuprates remains one of the most widely investigated, constantly surprising, and poorly understood phenomena in physics. Here, we describe briefly a new phenomenological theory inspired by the celebrated description of superconductivity due to Ginzburg and Landau and believed to describe its essence. This posits a free energy functional for the superconductor in terms of a complex order parameter characterizing it. We propose, for superconducting cuprates, a similar functional of the complex, in plane, nearest neighbor spin singlet bond (or Cooper) pair amplitude psi_ij. A crucial part of it is a (short range) positive interaction between nearest neighbor bond pairs, of strength J'. Such an interaction leads to nonzero long wavelength phase stiffness or superconductive long range order, with the observed d-wave symmetry, below a temperature T_c\simzJ' where z is the number of nearest neighbours; it is thus an emergent, collective consequence. Using the functional, we calculate a large range of properties, e.g. the pseudogap transition temperature T* as a function of hole doping x, the transition curve T_c(x), the superfluid stiffness rho_s(x,T), the specific heat (without and with a magnetic field) due to the fluctuating pair degrees of freedom, and the zero temperature vortex structure. We find remarkable agreement with experiment. We also calculate the self energy of electrons hopping on the square cuprate lattice and coupled to electrons of nearly opposite momenta via inevitable long wavelength Cooper pair fluctuations formed of these electrons. The ensuing results for electron spectral density are successfully compared with recent ARPES experiments, and comprehensively explain strange features such as temperature dependent Fermi arcs above T_c and the 'bending' of the superconducting gap below T_c .

description: While archaeological research in the Sudan has continued from the beginning of this century until the present, it has generally been of an unbalanced nature in terms of geographical cover age. Al though the UNESCO Campaign resulted in a strong emphasis on the study of the cultural history of medieval Nubia, it was restricted largely to the extreme north of the Sudan, Lower Nubia. As a result, the kingdom of Alwa in Southern Nubia remains largely a neglected chapter in medieval Nubian studies. In fact, the Kingdom has been described by some authorities as politically and culturally inferior to its counterpart in the north, the kingdom of Dongola. This study represents an introductory chapter on the history and culture of the medieval kingdom of Alwa. Fundamental to the analysis presented in this thesis is the notion of the interrelationship of the cultural past with the present in the Sudan. In fact, I propose that some definitional aspects of the kingdom of Alwa were formative in respect of subsequent periods in the history of the area. The strategic location and long existence of this kingdom suggest that Alwa played a role of yet unrecognized significance in the history of medieval Nubia, and, later, the Sudan. The analysis which follows is not meant to be a definitive statement of Alwan cultural history, but rather a presentation which may stimilate an exchange of ideas and help to clarify issues. It is also hoped that this exploratory work will serve as an introduction to the history of Alwa and its people, to stimilate interest and to orient the uninitiated to this field of study.

This results in a new, unitarily equivalent formulation of the theory on a generalized Bargmann space. Since integrals over the group are exchanged for straightforward integrals over the complex plane we expect this formalism to be useful to efficiently organize practical calculations.

description: We have observed the blazar Markarian 421 with the TACTIC $γ$-ray telescope at Mt. Abu, India, from 22 November 2009 to 16 May 2010 for 265 hours. Detailed analysis of the data so recorded revealed presence of a TeV $γ$-ray signal with a statistical significance of 12.12$σ$ at $E_γ\geq$ 1 TeV. We have estimated the time averaged differential energy spectrum of the source in the energy range 1.0 - 16.44 TeV. The spectrum fits well with the power law function of the form ($dF/dE=f_0 E^{-Γ}$) with $f_0=(1.39\pm0.239)\times 10^{-11}cm^{-2}s^{-1}TeV^{-1}$ and $Γ=2.31\pm0.14$.

description: Lyman-alpha emitting galaxies can be used to study cosmological reionization, because a neutral intergalactic medium scatters Lyman-alpha photons into diffuse halos whose surface brightness falls below typical survey detection limits. Here we present the Lyman-alpha emitting galaxy LAE J095950.99+021219.1, identified at redshift z=6.944 in the COSMOS field using narrowband imaging and followup spectroscopy with the IMACS instrument on the Magellan I Baade telescope. With a single object spectroscopically confirmed so far, our survey remains consistent with a wide range of IGM neutral fraction at redshift seven, but further observations are planned and will help clarify the situation. Meantime, the object we present here is only the third Lyman-alpha selected galaxy to be spectroscopically confirmed at redshift seven, and is 2--3 times fainter than the previously confirmed redshift seven Lyman alpha galaxies.

description: Two sharp existence and uniqueness theorems are presented for solutions of multiple vortices arising in a six-dimensional brane-world supersymmetric gauge field theory under the general gauge symmetry group $G=U(1)\times SU(N)$ and with $N$ Higgs scalar fields in the fundamental representation of $G$. Specifically, when the space of extra dimension is compact so that vortices are hosted in a 2-torus of volume $|\Om|$, the existence of a unique multiple vortex solution representing $n_1,...,n_N$ respectively prescribed vortices arising in the $N$ species of the Higgs fields is established under the explicitly stated necessary and sufficient condition \[ n_i

description: We investigate the quantum dynamics of particles on graphs ("quantum random walks"), with the aim of developing quantum algorithms for determining if two graphs are isomorphic (related to each other by a relabeling of vertices). We focus on quantum random walks of multiple non-interacting particles on strongly regular graphs (SRGs), a class of graphs with high symmetry that is known to have pairs of graphs that are hard to distinguish. Previous work has already demonstrated analytically that two-particle non-interacting quantum walks cannot distinguish non-isomorphic SRGs of the same family. Here, we demonstrate numerically that three-particle non-interacting quantum walks have significant, but not universal, distinguishing power for pairs of SRGs, proving a fundamental difference between the distinguishing power of two-particle and three-particle non-interacting walks. We analytically show why this distinguishing power is possible, whereas it is forbidden for two-particle non-interacting walks. Based on sampling of SRGs with up to 64 vertices, we find no difference in the distinguishing power of bosonic and fermionic walks. In addition, we find that the four-fermion non-interacting walk has greater distinguishing power than the three-particle walks on SRGs, showing that increasing particle number increases distinguishing power. However, we also analytically show that no non-interacting walk with a fixed number of particles can distinguish all SRGs, thus demonstrating a potential fundamental difference between the distinguishing power of interacting and noninteracting walks.

Non-gaussianity in axion N-flation models: detailed predictions and mass spectra

description: We have recently shown that multi-field axion N-flation can lead to observable non-gaussianity in much of its parameter range, with the assisted inflation mechanism ensuring that the density perturbations are sufficiently close to scale invariance. In this paper we extend our analysis in several directions. In the case of equal-mass axions, we compute the probability distributions of observables and their correlations across the parameter space. We examine the case of unequal masses, and show that the mass spectrum must be very densely packed if the model is to remain in agreement with observations. The model makes specific testable predictions for all major perturbative observables, namely the spectral index, tensor-to-scalar ratio, bispectrum, and trispectrum.

description: In massive gravity the so-far-found black hole solutions on Minkowski space happen to convert horizons into a certain type of singularities. Here we explore whether these singularities can be avoided if space-time is not asymptotically Minkowskian. We find an exact analytic black hole (BH) solution which evades the above problem by a transition at large scales to self-induced de Sitter (dS) space-time, with the curvature scale set by the graviton mass. This solution is similar to the ones discovered by Koyama, Niz and Tasinato, and by Nieuwenhuizen, but differs in detail. The solution demonstrates that in massive GR, in the Schwarzschild coordinate system, a BH metric has to be accompanied by the Stückelberg fields with nontrivial backgrounds to prevent the horizons to convert into the singularities. We also find an analogous solution for a Reissner-Nordström BH on dS space. A limitation of our approach, is that we find the solutions only for specific values of the two free parameters of the theory, for which both the vector and scalar fluctuations loose their kinetic terms, however, we hope our solutions represent a broader class with better behaved perturbations.

description: The possibility of finding multistability in the density and current of an interacting nanoscale junction coupled to semi-infinite leads is studied at various levels of approximation. The system is driven out of equilibrium by an external bias and the non-equilibrium properties are determined by real-time propagation using both time-dependent density functional theory (TDDFT) and many-body perturbation theory (MBPT). In TDDFT the exchange-correlation effects are described within a recently proposed adiabatic local density approximation (ALDA). In MBPT the electron-electron interaction is incorporated in a many-body self-energy which is then approximated at the Hartree-Fock (HF), second-Born (2B) and GW level. Assuming the existence of a steady-state and solving directly the steady-state equations we find multiple solutions in the HF approximation and within the ALDA. In these cases we investigate if and how these solutions can be reached through time evolution and how to reversibly switch between them. We further show that for the same cases the inclusion of dynamical correlation effects suppresses bistability.

description: In this paper we compute the coefficients of the heat kernel asymptotic expansion for Laplace operators acting on scalar functions defined on the so called spherical suspension (or Riemann cap) subjected to Dirichlet boundary conditions. By utilizing a contour integral representation of the spectral zeta function for the Laplacian on the spherical suspension we find its analytic continuation in the complex plane and its associated meromorphic structure. Thanks to the well known relation between the zeta function and the heat kernel obtainable via Mellin transform we compute the coefficients of the asymptotic expansion in arbitrary dimensions. The particular case of a $d$-dimensional sphere as the base manifold is studied as well and the first few heat kernel coefficients are given explicitly.

description: This is the first article of a projected series of reports concerning the architecture and conservation of the Church of the Redeemer (Surb Prkich) in the medieval Armenian capital of Ani in the present-day Turkish province of Kars. Dated to 1035, this polyconch church stands as a beautiful example of the metropolitan school, which was especially dedicated to interpreting the architectural forms and principles of Classical antiquity. The church has survived both medieval reconstructions and a subsequent restoration in 1912, as well as remained extant within the ruins of Ani despite its western half preserved in poor condition. The authors, two Turkish architects and a Russian architectural historian have analyzed the historical data, historiography and architectural plan of Surb Prkich and present here the results of cleaning and archeological excavations at the site, as well as of the initiation of the monument’s stabilization and conservation program, begun in 2012.
