Alterpieces: Artworks as Shifting Speech Acts

description: Art viewers and critics talk as if visual artworks say things, express messages, or have meanings. For instance, Picasso’s 'Guernica' has been described as a “generic plea against the barbarity and terror of war”, forming a “powerful anti-war statement”. One way of understanding meaning in art is to draw analogies with language. My thesis explores how the notion of a speech act – an utterance with a performative aspect – can illuminate art’s power to ‘speak’. In recent years, philosophers of art have explored speech act theory in relation to literary art, though barely at all in relation to visual art. Given the way we talk about painting, sculpture, installation, film, and photography, and given that artists have investigated performativity through their art, this neglect is surprising. My thesis develops two main arguments. First, artwork meaning is active. I argue that visual artworks, under certain conditions, are speech acts. They have propositional content, and they have a certain force: they can do things such as assert, protest, and criticise – things we would normally do with words. I defend these contested claims against several dissenters, and explore some consequences: in particular, I explore how art can lie, a hitherto neglected question. Second, artwork meaning is flexible. I argue that what an artwork says and does is affected by the context in which it’s displayed, and in particular, by its curation. As a result, an artwork’s content and force can vary from context to context. This goes against a dominant view in the philosophy of art – what I call ‘Originalism’ – that the meaning of an artwork is fixed by factors which held at the time of the work’s creation, and so cannot change across time. I argue that this is mistaken: artworks can change in meaning. Curatorial factors can affect an artwork’s content and force, and consequently its social effects. It is known that our verbal speech has the power to oppress and liberate people in a society. My thesis aims to show that art also has this power to shape society; through what it says, and through what it does.

description: The current Universe is composed by a mixture of relativistic species, baryonic matter, dark matter and dark energy which evolve in a non-trivial way at perturbative level. An advanced description of the cosmological dynamics should include non-standard features beyond the simplistic approach idealized by the standard cosmology in which cosmic components do not interact, are adiabatic and dissipationless. We promote a full perturbative analysis of linear scalar perturbations of a non-interacting cosmological model containing baryons, dark matter (both pressureless) and a scalar field allowing for the presence of relative entropic perturbations between the three fluids. Assuming an effective scalar-field sound speed equal to one and neglecting anisotropic stresses we establish a new set of equations for the scalar cosmological perturbations. As a consequence of this new approach, we show that tiny departures from a constant scalar field equation of state $w_S=-1$ damage structure formation in a non-acceptable manner. Hence, by strongly constraining $w_S$ our results provide compelling evidence in favor of the standard cosmological model and rule out a large class of dynamical dark energy models

The Origins of the Vietnam War from the East- and West German Perspective, 1960-1965

description: This dissertation is the first analytical account of both the East- and West German perspective of the Vietnam War during the spring of 1960 and military escalation in the summer of 1965. By examining the GDR’s and FRG’s opinions and appraisals in these pivotal years, it challenges the prevalent scholarly argument that the roots of the conflicts origins were located in the Cold War struggle between Capitalism and Marxism-Leninism. The study, instead, illustrates how structural changes in the Eastern- and Western Bloc shaped the way in which Bonn and East Berlin reacted to the crisis. It argues that the causes of the Vietnam War cannot be explained without chronicling the breakup of the post-war international order and the subsequent shift from bipolarism to polycentrism. Not only does this thesis enhance our understanding of East- and West German decision-making, but also provides a new contribution to the historiography of the Vietnam War. Above all, it delineates events on either side of the 17th Parallel to ascertain how and why the struggle evolved the way it did.
A Model for Abundances in Metal-Poor Stars

The H events are of high frequency and produce dominantly heavy (A>130) r-elements but no Fe (presumably leaving behind black holes). The L events are of low frequency and produce Fe and dominantly light (A<130) r-elements (essentially none above Ba). By using the observed abundances in two ultra-metal-poor stars and the solar r-abundances, the initial or prompt inventory of elements produced by the first generations of very massive stars and the yields of H and L events can be determined. The abundances of a large number of elements in a star can then be calculated from the model by using only the observed Eu and Fe abundances. To match the model results and the observational data for stars with -3

description: We analyze the high-resolution X-ray spectrum of the Seyfert 1 galaxy NGC 5548, for the full 0.1-10 keV band, using improved calibration results of the Chandra-LETGS instrument. The warm absorber consists of at least three ionization components, namely one with a low, medium and high ionization parameter. The X-ray absorbing material, from an outflowing wind, covers the full range of velocity components found from UV absorption lines. The presence of redshifted emission components for the strongest blue-shifted resonance absorption lines indicate that the absorber is located at a distance larger than the edge of the accretion disk. We derive an upper limit to the edge of the accretion disk of 1 light year. Absorption lines from ions of at least ten chemical elements have been detected, and in general for these elements there are no strong deviations from solar abundances. The narrow emission lines from the O VII and Ne IX forbidden and intercombination lines probably originate from much larger distances to the black hole. We find evidence for weak relativistically broadened oxygen and nitrogen emission lines from the inner parts of the accretion disk, but at a much smaller flux level than those observed in some other active galactic nuclei. In addition, there is a broad, non-relativistic C VI Ly alpha emission line that is consistent with emission lines from the inner part of the optical/UV broad line region.

description: Variational quantum algorithms are promising applications of noisy intermediate-scale quantum (NISQ) computers. These algorithms consist of a number of separate prepare-and-measure experiments that estimate terms in a Hamiltonian. The number of terms can become overwhelmingly large for problems at the scale of NISQ hardware that may soon be available. We approach this problem from the perspective of contextuality, and use unitary partitioning (developed independently by Izmaylov et al. [J. Chem. Theory Comput. 16, 190 (2020)]) to define variational quantum eigensolver procedures in which additional unitary operations are appended to the ansatz preparation to reduce the number of terms. This approach may be scaled to use all coherent resources available after ansatz preparation. We also study the use of asymmetric qubitization to implement the additional coherent operations with lower circuit depth. We investigate this technique for lattice Hamiltonians, random Pauli Hamiltonians, and electronic structure Hamiltonians. Using this technique, we find a constant factor speedup for lattice and random Pauli Hamiltonians. For electronic structure Hamiltonians, we prove that linear term reduction with respect to the number of orbitals, which has been previously observed in numerical studies, is always achievable. For systems represented on 10--30 qubits, we find that there is a reduction in the number of terms by approximately an order of magnitude. Applied to the plane-wave dual basis representation of fermionic Hamiltonians, however, unitary partitioning offers only a constant factor reduction. Finally, we show that noncontextual Hamiltonians may be reduced to effective commuting Hamiltonians using unitary partitioning.

description: Mycobacterium abscessus is an emerging pathogen with infections increasing worldwide, especially among Cystic Fibrosis (CF) patients. During my PhD, I studied key aspects of the biology of M. abscessus spp.; particularly, I studied host-pathogen interactions, antimicrobial resistance mechanisms, and genetic determinants of virulence. First, I performed phenotypic characterization of M. abscessus spp. clinical isolates obtained from CF patients classified according to subspecies and clustering. I found clustered isolates, representing probable transmission events, were phenotypically distinct from sporadic isolates and showed adaptation phenotypes associated with chronic lung infection, such as enhanced intracellular survival, increased antibiotic resistance, and metabolic adaptations to the host environment. Second, I assessed the role of an inserted element containing an active methyltransferase in M. a. massiliense. Infection experiments with an isolate containing the inserted element (BIR1049wt) and a knockout strain (BIR1049Δ1809078_1815649) showed decreased survival of BIR1049Δ1809078_1815649 within macrophages. RNAseq analysis showed a distinct gene expression pattern between both isolates, with a number of mycobacterial virulence factors upregulated in BIR1049wt. Third, I studied heritable non-mutational antibiotic resistance mechanisms in M. abscessus to linezolid and clofazimine. For both antibiotics, I found clonal isolates of M. abscessus spp. with varying susceptibilities and different gene expression patterns, suggesting transcriptional regulation of antibiotic resistance. Mutation- mediated resistance to clofazimine was also found due to mutations in two transcriptional regulators predicted to regulate efflux pumps. Last, I evaluated the potential of repurposing a kinase inhibitor (compound H) in clinical trials for the treatment of cancer and CF, to treat M. abscessus infection. I found compound H enhanced killing of intracellular M. abscessus in macrophages through stimulation of autophagy and lysosomal function. I further studied over 60 chemical analogues of compound H in order to find a more active and specific compound for M. abscessus infection.

Relativistic models and the jet velocity field in the radio galaxy 3C 31

description: We show that the principal differences in appearance of the main and counter-jets within 30 arcsec of the nucleus of the low-luminosity radio galaxy 3C 31 can result entirely from the effects of relativistic aberration in two symmetrical, antiparallel, axisymmetric, time-stationary relativistic flows. We develop empirical parameterized models of the jet geometry and the three-dimensional distributions of the velocity, emissivity and magnetic-field structure and optimize their parameters by fitting the predicted synchrotron intensity and polarization to deep 8.4-GHz VLA observations. We conclude that the jets are at roughly 52 degrees to the line of sight, that they decelerate and that they have transverse velocity gradients. They have three regions with distinct kinematics: a narrow inner region; a flaring region of rapid expansion followed by recollimation and a conical outer region. There is a discontinuity in the flow between inner and flaring regions. The on-axis velocity is close to 0.8c until the end of the flaring region, where it drops abruptly to 0.55c, thereafter falling more slowly to 0.25c at the end of the modelled region. Throughout the flaring and outer regions, the velocity at the edge of the jet is 0.7 of its on-axis value. The magnetic field has primarily toroidal and longitudinal components except in the flaring region, where there is a significant radial component at the jet edge. Simple adiabatic models fail in the inner and flaring regions. The inferred transverse velocity profiles and field structure in the flaring region support the idea that the jets decelerate by entraining the external medium. We demonstrate the appearance of our model at other angles to the line of sight and argue that other low-luminosity radio galaxies resemble 3C 31 seen at different orientations. [Abridged]

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: Lead halide perovskites have shown remarkable device performance in both solar cells and LEDs. Whilst the research efforts so far have been mainly focussed on device optimisation, little is known about the photophysical properties. For example, the nature of the bandgap is still debated and an indirect bandgap due to a Rashba splitting has been suggested. In this thesis, we study the early-time carrier relaxation and its impact on photoluminescence emission. We first study ultrafast carrier thermalization processes using 2D electronic spectroscopy and extract characteristic carrier thermalization times from below 10 fs to 85 fs. We then investigate the early-time photoluminescence emission during carrier cooling. We observe that the luminescence signal shows a rise over 2 picoseconds in CH3NH3PbI3 while carriers cool to the band edge. This shows that luminescence of hot carriers is slower than that of cold carriers, as is found in direct gap semiconductors. We conclude that electrons and holes show strong overlap in momentum space, despite the potential presence of a small band offset arising from a Rashba effect. Recombination and device performance of perovskites are thus better described within a direct bandgap model. We finally study carrier recombination in perovskites and the impact of photon recycling. We show that, for an internal photoluminescence quantum yield of 70%, we measure external yields as low as 15% in planar films, where light out-coupling is inefficient, but observe values as high as 57% in films on textured substrates that enhance out-coupling. We study the photo-excited carrier dynamics and use a rate equation to relate radiative and non-radiative recombination events to measured photoluminescence efficiencies. We conclude that the use of textured active layers has the ability to improve power conversion efficiencies for both LEDs and solar cells.

description: Consider a matrix $M$ chosen uniformly at random from a class of $m \times n$ matrices of zeros and ones with prescribed row and column sums. A partially filled matrix $D$ is a $\mathit{defining}$ $\mathit{set}$ for $M$ if $M$ is the unique member of its class that contains the entries in $D$. The $\mathit{size}$ of a defining set is the number of filled entries. A $\mathit{critical}$ $\mathit{set}$ is a defining set for which the removal of any entry stops it being a defining set. For some small fixed $ε>0$, we assume that $n\le m=o(n^{1+ε})$, and that $λ\le1/2$, where $λ$ is the proportion of entries of $M$ that equal $1$. We also assume that the row sums of $M$ do not vary by more than $\mathcal{O}(n^{1/2+ε})$, and that the column sums do not vary by more than $\mathcal{O}(m^{1/2+ε})$. Under these assumptions we show that $M$ almost surely has no defining set of size less than $λmn-\mathcal{O}(m^{7/4+ε})$. It follows that $M$ almost surely has no critical set of size more than $(1-λ)mn+\mathcal{O}(m^{7/4+ε})$. Our results generalise a theorem of Cavenagh and Ramadurai, who examined the case when $λ=1/2$ and $n=m=2^k$ for an integer $k$.

description: We predict and study the quantum-electrodynamical effect of parametric self-induced excitation of a molecule moving above the dielectric or conducting medium with periodic grating. In this case the radiation reaction force modulates the molecular transition frequency which results in a parametric instability of dipole oscillations even from the level of quantum or thermal fluctuations. The present mechanism of instability of electrically neutral molecules is different from that of the well-known Smith-Purcell and transition radiation in which a moving charge and its oscillating image create an oscillating dipole. We show that parametrically excited molecular bunches can produce an easily detectable coherent radiation flux of up to a microwatt.

 ‘fitting’ method in Release 21 of AnalysisBase. It was found that the Z 0
 decay processes have a large discrepancy in the percentage of
 misidentified Hard Scatter vertices between Monte Carlo simulation and
 data unlike in the tt¯ channel where

 Monte Carlo and data agreed. The percentage of misidentified Hard Scatter
 vertices was also found to be far greater in Z 0 decays than tt¯. The
 fitting method was then developed for Release 22, and found that the HS
 efficiency was much better than Release 21, with the HS efficiency for Z 0
 → ℓℓ events comparable to the efficiency of tt¯ events in Release 21. The
 second part is the main physics analysis, aiming to test a fundamental
 axiom of the Standard

 Model, Lepton Flavour Universality, the hypothesis that the couplings of
 each lepton flavour to the electroweak gauge bosons are the same
 regardless of flavour. The aim of the analysis presented is to test lepton
 flavour universality through the measurement of the of the rate of decay
 of W bosons to τ-leptons and electrons, R(τ/e) = B(W → τντ )/B(W → eνe).
 Di-leptonic tt¯ events are based on 139 f b−1 of data recorded with the
 ATLAS detector in proton–proton collisions at √s = 13TeV. The analysis
 follows a ‘tag and probe’ method; one lepton is the tag to select events,
 the other a probe to determine if the lepton comes from a ‘prompt’ decay,
 W → eνe, or an intermediate τ lepton, W → τντ → eνeντντ . The result of
 the analysis is still blinded as it is still in the approval

 process by the ATLAS collaboration. The expected precision of the
 measurement of R(τ/e) is 0.0234.
Solar Neutrino Limits on Decoherence

description: The solar neutrino flux arrives at Earth as an incoherent admixture of mass eigenstates, and then solar neutrino detection constitute a blind probe to the oscillation pattern of the neutrino flavour conversion. Consequently, it is also impossible to probe, in a model independent approach, any new physics that leads to an enhancement of decoherence during the neutrino evolution, an effect that is present for instance in Open Quantum System formalism. However, such mechanism can also induce changes between mass eigenstates if an energy interchange between the neutrino subsystem and the reservoir is not explicitly forbidden. In this work the conversion probabilities between mass eigenstates in an Open Quantum System are calculated, and limits are stablished for these kind of transitions. We present our results in a pedagogical way, pointing out how far the analysis can go without any assumption on the neutrino conversion physics inside the Sun, before performing the full calculations. We obtain as limits for the decoherence parameters the values of $ Γ_3< 6.5\times 10^{-19}$ eV and $Γ_8< 7.1\times 10^{-19}$ eV at 3$σ$.

Matrix controlled channel diffusion of sodium in amorphous silica

description: To find the origin of the diffusion channels observed in sodium-silicate glasses, we have performed classical molecular dynamics simulations of Na$_2$O--4SiO$_2$ during which the mass of the Si and O atoms has been multiplied by a tuning coefficient. We observe that the channels disappear and that the diffusive motion of the sodium atoms vanishes if this coefficient is larger than a threshold value. Above this threshold the vibrational states of the matrix are not compatible with those of the sodium ions. We interpret hence the decrease of the diffusion by the absence of resonance conditions.

Volumetric Imaging Across Spatiotemporal Scales in Biology with Fluorescence Microscopy

description: Quantitative three dimensional maps of cellular structure, activity and function provide the key to answering many prevalent questions in modern biological research. Fluorescence microscopy has emerged as an indispensable tool in generating such maps, but common techniques are limited by fundamental physical constraints which render them incapable of simultaneously achieving high spatial and temporal resolution. This thesis will describe the development of novel microscopy techniques and complementary computational tools capable of addressing some of the aforementioned limitations of fluorescence microscopy and further outline their application in providing novel biological insights. The first section details the design of a light sheet microscope capable of high-throughput imaging of cleared, macroscopic samples with cellular resolution. In light sheet microscopy, the combination of spatially confined illumination with widefield detection enables multi-megapixel acquisition in a single camera exposure. The corresponding increase in acquisition speed enables systems level biological studies to be performed. The ability of this microscope to perform rapid, high-resolution imaging of intact samples is demonstrated by its application in a project which established a niche and hierarchy for stem cells in the adult nervous system. Light sheet microscopy achieves fast volumetric imaging rates, but the two dimensional nature of each measurement results in an inevitable lag between acquisition of the initial and final planes. The second section of this thesis describes the development and optimization of a light field microscope which captures volumetric information in a snapshot. Light field microscopy is a computational technique and images are reconstructed from raw data. Both the fidelity of computed volumes and the efficiency of the algorithms are strongly dependent on the quality of the rectification. A highly accurate, automated procedure is presented in this section. Light field reconstruction techniques are investigated and compared and the results are used to inform the re-design of the microscope. The new optical configuration is demonstrated to minimize the long-object problem. In the final section of the thesis, the spatial resolution limits of light field microscopy are explored using a combination of simulations and experiments. It is shown that light field microscopy is capable of localizing point sources over a large depth of field with high axial and lateral precision. Notably, this work paves the way towards frame rate limited super resolution localization microscopy with a depth of field larger than the thickness of a typical mammalian cell.

description: This paper studies a tensor-structured linear regression model with a scalar response variable and tensor-structured predictors, such that the regression parameters form a tensor of order $d$ (i.e., a $d$-fold multiway array) in $\mathbb{R}^{n_1 \times n_2 \times \cdots \times n_d}$. It focuses on the task of estimating the regression tensor from $m$ realizations of the response variable and the predictors where $m\ll n = \prod \nolimits_{i} n_i$. Despite the seeming ill-posedness of this problem, it can still be solved if the parameter tensor belongs to the space of sparse, low Tucker-rank tensors. Accordingly, the estimation procedure is posed as a non-convex optimization program over the space of sparse, low Tucker-rank tensors, and a tensor variant of projected gradient descent is proposed to solve the resulting non-convex problem. In addition, mathematical guarantees are provided that establish the proposed method linearly converges to an appropriate solution under a certain set of conditions. Further, an upper bound on sample complexity of tensor parameter estimation for the model under consideration is characterized for the special case when the individual (scalar) predictors independently draw values from a sub-Gaussian distribution. The sample complexity bound is shown to have a polylogarithmic dependence on $\bar{n} = \max \big\{n_i: i\in \{1,2,\ldots,d \} \big\}$ and, orderwise, it matches the bound one can obtain from a heuristic parameter counting argument. Finally, numerical experiments demonstrate the efficacy of the proposed tensor model and estimation method on a synthetic dataset and a collection of neuroimaging datasets pertaining to attention deficit hyperactivity disorder. Specifically, the proposed method exhibits better sample complexities on both synthetic and real datasets, demonstrating the usefulness of the model and the method in settings where $n \gg m$.

description: In this note we announce some results extending our recent work with A. Toufik on the free-fermion point $q=i$ of the Haldane-Shastry chain to the case with an even number N of sites. The resulting long-range version of the Heisenberg XX chain may be viewed as a model of fermions with extended gl(1|1) symmetry. Unlike for odd N, the conserved charges are nilpotent and exhibit Jordan blocks.
Detecting Eccentric Globular Cluster Binaries with LISA

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: The energy carried in the gravitational wave signal from an eccentric binary is spread across several harmonics of the orbital frequency. The inclusion of the harmonics in the analysis of the gravitational wave signal increases the signal-to-noise ratio of the detected signal for binaries whose fundamental frequency is below the galactic confusion-limited noise cut-off. This can allow for an improved angular resolution for sources whose orbital period is greater than 2000 s. Globular cluster sources include possible binary black holes and neutron stars which may have high eccentricities. Cluster dynamics may also enhance the eccentricities of double white dwarf binaries and white dwarf-neutron star binaries over the galactic sources. Preliminary results of the expected signal-to-noise ratio for selected globular cluster binaries are presented.

description: We report precise Doppler measurements of the stars HD 216437, HD 196050 and HD 160691 obtained with the Anglo-Australian Telescope using the UCLES spectrometer together with an iodine cell as part of the Anglo-Australian Planet Search. Our measurements reveal periodic Keplerian velocity variations that we interpret as evidence for planets in orbit around these solar type stars. HD 216437 has a period of 1294$\pm$250 d, a semi-amplitude of 38$\pm$4 m s$^{-1}$ and of an eccentricity of 0.33$\pm$0.09. The minimum (M sin $i$) mass of the companion is 2.1$\pm$0.3 M$_{\rm JUP}$ and the semi-major axis is 2.4$\pm$0.5 au. HD 196050 has a period of 1288$\pm$230 d, a semi-amplitude of 54$\pm$8 m s$^{-1}$ and an eccentricity of 0.28$\pm$0.15. The minimum mass of the companion is 3.0$\pm$0.5 M$_{\rm JUP}$ and the semi-major axis is 2.3$\pm$0.5 au. We also report further observations of the metal rich planet bearing star HD 160691. Our new solution confirms the previously reported planet and shows a trend indicating a second, longer-period companion. These discoveries add to the growing numbers of midly-eccentric, long-period extra-solar planets around Sun-like stars. As seems to be typical of stars with planets, both stars are metal-rich.
