description: Consider the nonlinear and completely continuous scattering map \[ \mathcal{S}\big((Ω; λ, μ, V), \mathbf{u}^i\big)=\mathbf{u}_t^\infty(\hat{\mathbf{x}}), \quad \hat{\mathbf{x}}\in\mathbb{S}^{n-1}, \] which sends an inhomogeneous elastic scatterer $(Ω; λ, μ, V)$ to its far-field pattern $\mathbf{u}_t^\infty$ due to an incident wave field $\mathbf{u}^i$ via the Lamé system. Here, $(λ, μ, V)$ signifies the medium configuration of an elastic scatterer that is compactly supported in $Ω$. In this paper, we are concerned with the intrinsic geometric structure of the kernel space of $\mathcal{S}$, which is of fundamental importance to the theory of inverse scattering and invisibility cloaking for elastic waves and has received considerable attention recently. It turns out that the study is contained in analysing the geometric properties of a certain non-selfadjoint and non-elliptic transmission eigenvalue problem. We propose a generalized elastic transmission eigenvalue problem and prove that the transmission eigenfunctions vanish locally around a corner of $\partialΩ$ under generic regularity criteria. The regularity criteria are characerized by the Hölder continuity or a certain Fourier extension property of the transmission eigenfunctions. As an interesting and significant application, we apply the local geometric property to derive several novel unique identifiability results for a longstanding inverse elastic problem by a single far-field measurement.

description: Title: Understanding bereavement support for staff in an Irish Higher Education Institute. How are staff members supported when they experience bereavement?Background: While employers in Ireland typically grant some time off after the death of a loved one, there is no statutory entitlement to do so. As a result workplace policies may vary with limited discretionary leave available. Returning to work after bereavement may also be interpreted as a resumption of normal service where life and work goes on despite recent events.Problem Description: There is a lack of understanding about how staff are supported after a bereavement. The lived experiences of bereaved staff has not been scrutinised and there is no current standalone bereavement policy either nationally or institutionally.Methods and Process Methods: as described here include the planned framework and the shift in methodological emphasis brought about by covid-19 restrictions. Action Research was used to explore the issue of bereavement at work and to engage with stakeholders within the institution. Bereaved staff, managers and senior policy makers were identified as key cohorts in the project. Data collection using qualitative semi structured face-to-face interviews and focus groups were planned. Research ethics approval to conduct the study was obtained. Results: Informal discussions were held and successful engagement with project stakeholders was established.Conclusions: Action Research focuses on real world problems and takes place in real time. Recent global events have affected this project and the overall plan has changed. However, the project is sufficiently well developed so that it can be recommenced when appropriate.

description: Kinetically constrained models (KCM) are systems with trivial thermodynamics but often complex dynamical behavior due to constraints on the accessible paths followed by the system. Exploring these properties, the Kob-Andersen (KA) model was introduced to study the slow dynamics of glass forming liquids and later extended to granular materials. In this last context, we present new results on the heterogeneous character of both in and out of equilibrium dynamics, further stretching the granular-glass analogy.

description: Gravitational wave observations of binary neutron star mergers provide valuable information about neutron star structure and the equation of state of dense nuclear matter. Numerous methods have been proposed to analyze the population of observed neutron stars and previous work has demonstrated the necessity of jointly fitting the astrophysical distribution and the equation of state in order to accurately constrain the equation of state. In this work, we introduce a new framework to simultaneously infer the distribution of binary neutron star masses and the nuclear equation of state using Gaussian mixture model density estimates which mitigates some of the limitations previously-used methods suffer from. Using our method, we reproduce previous projections for the expected precision of our joint mass distribution and equation of state inference with tens of observations. We also show that mismodeling the equation of state can bias our inference of the neutron star mass distribution. While we focus on neutron star masses and matter effects, our method is widely applicable to population inference problems.

description: Synchronization of stochastic phase-coupled oscillators is known to occur but difficult to characterize because sufficiently complete analytic work is not yet within our reach, and thorough numerical description usually defies all resources. We present a discrete model that is sufficiently simple to be characterized in meaningful detail. In the mean field limit, the model exhibits a supercritical Hopf bifurcation and global oscillatory behavior as coupling crosses a critical value. When coupling between units is strictly local, the model undergoes a continuous phase transition which we characterize numerically using finite-size scaling analysis. In particular, we explicitly rule out multistability and show that that the onset of global synchrony is marked by signatures of the XY universality class. Our numerical results cover dimensions d=2, 3, 4, and 5 and lead to the appropriate XY classical exponents βand ν, a lower critical dimension d_{lc} = 2, and an upper critical dimension d_{uc}=4.
A rapid transition of $G_{\rm eff}$ at $z_t \simeq 0.01$ as a solution of the Hubble and growth tensions

description: The mismatch in the value of the Hubble constant from low- and high-redshift observations may be recast as a discrepancy between the low- and high-redshift determinations of the luminosity of Type Ia supernovae, the latter featuring an absolute magnitude which is $\approx 0.2$~mag lower. Here, we propose that a rapid transition in the value of the relative effective gravitational constant $μ_G\equiv\frac{G_{\rm eff}}{G_N}$ at $z_t\simeq 0.01$ could explain the lower luminosity (higher magnitude) of local supernovae, thus solving the $H_0$ crisis. A model that features $μ_G = 1$ for $z \lesssim 0.01$ but $μ_G \simeq 0.9$ for $z \gtrsim 0.01$ is trivially consistent with local gravitational constraints but would raise the Chandrasekhar mass and so decrease the absolute magnitude of Type Ia supernovae at $z \gtrsim 0.01$ by the required value of $\approx 0.2$~mag. Such a rapid transition of the effective gravitational constant would not only resolve the Hubble tension but it would also help resolve the growth tension as it would reduce the growth of density perturbations without affecting the Planck/$Λ$CDM background expansion.

description: The long-standing problem of dramatic structure change near N=40 in Ge isotopes is investigated by means of large-scale shell model calculation. The analysis of simulated calculations suggests a possible understanding of the problem in terms of rapid increase in the $g_{9/2}$ proton and neutron occupation. The observed variation in excitation of the second $0^+$ state in $^{70,72,74}$Ge appears to correlate closely with the $g_{9/2}$ occupations induced by strong proton-neutron interactions. The enhancement of the $g_{9/2}$ occupancies is probably due to correlations in the $1g2d3s$ shell.

description: Chronic lymphocytic leukaemia is a B- cell malignancy that has been the subject of a great deal of progress both in understanding disease pathophysiology and in the development of new therapies. The recognition of a subgroup of patients that responds poorly to standard therapy has inspired a plethora of research into improving treatment outcomes. Retinoids have well-reported effects as anti-proliferation agents and have an established role in promoting cell differentiation. These properties have led them to be extensively studied in cancers in the contexts of prophylaxis and treatment.In this study we explore the effects of the retinoid derivative acitretin on CLL cell viability, migration and CD38 expression in vitro. In our clinical practice, a patient with stage A CLL as well as a diagnosis of squamouscell carcinoma of the skin was started on acitretin for the purpose of controlling his skin cancer. During follow-up it was noted that his lymphocyte count normalised within a month of starting acitretin. This observation led to preliminary in vitro studies investigating acitretin on primary patient cells.Acitretin significantly increased CD38 expression in MEC-1 cells as well as in CLL cells from CD38-positive patient samples but did so to a far lesser degree on samples from CD38-negative patients. We also show that acitretin reduced the migration of CLL cells toward CXCL12 in the majority of samples tested. Acitretin however had a very modest effect on CLL viability and apoptosis.Our results provide evidence that retinoids may have a role to play as an adjunct to drug treatment in CLL. We suggest that they should be considered for further studies in vivo and in perhaps in clinical trials, and that particular consideration should be given to studying them in combination with anti-CD38 monoclonal antibody drugs.

description: We consider an interferometer based on artificially induced topological superconductivity and chiral 1D Majorana fermions. The (non-topological) superconducting island inducing the superconducting correlations in the topological substrate is assumed to be floating. This allows probing the physics of interfering Majorana modes via microwave response, i.e., the frequency dependent impedance between the island and the earth. Namely, charging and discharging of the island is controlled by the time-delayed interference of chiral Majorana excitations in both normal and Andreev channels. We argue that microwave measurements provide a direct way to observe the physics of 1D chiral Majorana modes.

Subjects: Bandello; novella del Cinquecento; novella in the 16th century; Machiavelli; Froissart; Cornazzano

description: La nota dichiarazione di Bandello che le sue novelle non sono «fabule, ma vere istorie» ha una varia e articolata declinazione nell’ambito finzionale del Novelliere, nel quale non di rado emergono, con un ruolo tutt’altro che privo di significato, racconti che per ambiti, fatti e personaggi hanno una riconoscibile o pretesa corrispondenza a materia e fonti di matrice storiografica. È questo il caso delle due novelle prescelte come oggetto di analisi, per sondare modalità di scrittura e riscrittura messe in atto in tale prospettiva dall’autore: la novella incipitaria dell’intera opera I, 1, di cui sono fonte le Istorie machiavelliane, e la II, 37, di particolare interesse per la complessa e peculiare struttura, in cui sono tra loro contaminate vicende appartenenti a tempi storici differenti. The development and meaning of Bandello’s famous assertion – that his short stories are not fiction but true history – are varied and rich. In the literary and fictional world that he depicts with the colours of an illusory realism, it is not rare to find meaningful tales in which frame, events and characters are clearly or claimed congruent and consonant with historical subjects and sources. This is the case of the two tales analyzed here to investigate Bandello’s writing and his reworking sources: the first one of the whole work (I, 1), the source of which is Machiavelli, and the much wider II, 37, particularly interesting for its complex structure that makes up events from different historical times together.

description: (Context) When a galaxy acquires material from the outside, it is likely that the resulting angular momentum of the accreted material is decoupled from that of the pre-existing galaxy. The presence of stars counter-rotating with respect to other stars and/or gas represents an extreme case of decoupling. (Aims) NGC5719, an almost edge-on Sab galaxy with a prominent skewed dust lane, shows a spectacular on-going interaction with its face-on Sbc companion NGC5713. Observations of such interacting systems provide insight into the processes at work in assembling and reshaping galaxies. (Methods) Studies were made of the distribution and kinematics of neutral hydrogen in the NGC5719/13 galaxy pair and the ionised gas and stellar kinematics along the major axis of NGC5719. (Results) Two HI tidal bridges that loop around NGC5719 and connect to NGC5713, and two HI tidal tails departing westward from NGC5713 were detected. There is a correspondence between the HI condensations and the location of clumps of young stars within and outside the disc of NGC5719. The low-mass satellite PGC135857 at the tip of the northern tail was detected in HI, and is likely a by-product of the interaction. The neutral and ionised hydrogen in the disc of NGC5719 are counter-rotating with respect to the main stellar disc. The counter-rotating stellar disc contains about 20% of the stars in the system, and has the same radial extension as the main stellar disc. This is the first interacting system in which a counter-rotating stellar disc has been detected. (Conclusions) The data support a scenario where HI from the large reservoir available in the galaxy's surroundings was accreted by NGC5719 onto a retrograde orbit and subsequently fuelled the in-situ formation of the counter-rotating stellar disc.

description: L’obiettivo di questo articolo è illustrare alcuni elementi emersi durante la stesura dell’edizione critica della Paternostre di Silvestre, autore attivo alla corte di Ida di Boulogne nell’ultimo quarto del secolo XII. Il testo, un lungo sermon in couplets d’octosyllabes à rimes plates, si inserisce nel panorama delle parafrasi e dei commenti al Pater noster. L’analisi testuale dell’opera ha consentito di rilevare, nelle attestazioni seriori, la presenza di “aggiornamenti” in chiave francescana e borghese, testimoni del successo che la Paternostre sembra aver avuto anche al di fuori dell’ambiente benedettino per la quale era stata concepita. The article aims to present some elements revealed during the study of the Paternostre, a sermon written by Silvestre, a writer who lived in the court of Ide de Boulogne in the last quarter of the XII century. The text is written in couplets d’octosyllabes à rimes plates and it fits into the panorama of Pater noster paraphrases and comments. In the latest manuscripts Franciscan and bourgeois revision witness the success that Paternostre might have had even outside the Benedectine environment for which it was conceived.

description: We demonstrate a layer- and time-resolved measurement of ferromagnetic resonance (FMR) in a Ni81Fe19 / Cu / Co93Zr7 trilayer structure. Time-resolved x-ray magnetic circular dichroism has been developed in transmission, with resonant field excitation at a FMR frequency of 2.3 GHz. Small-angle (to 0.2 degree), time-domain magnetization precession could be observed directly, and resolved to individual layers through elemental contrast at Ni, Fe, and Co edges. The phase sensitivity allowed direct measurement of relative phase lags in the precession oscillations of individual elements and layers. A weak ferromagnetic coupling, difficult to ascertain in conventional FMR measurements, is revealed in the phase and amplitude response of individual layers across resonance.

Uniform Elgot Iteration in Foundations

description: Category theory is famous for its innovative way of thinking of concepts by their descriptions, in particular by establishing universal properties. Concepts that can be characterized in a universal way receive a certain quality seal, which makes them easily transferable across application domains. The notion of partiality is however notoriously difficult to characterize in this way, although the importance of it is certain, especially for computer science where entire research areas, such as synthetic and axiomatic domain theory revolve around notions of partiality. More recently, this issue resurfaced in the context of (constructive) intensional type theory. Here, we provide a generic categorical iteration-based notion of partiality, which is arguably the most basic one. We show that the emerging free structures, which we dub uniform-iteration algebras enjoy various desirable properties, in particular, yield an equational lifting monad. We then study the impact of classicality assumptions and choice principles on this monad, in particular, we establish a suitable categorial formulation of the axiom of countable choice entailing that the monad is an Elgot monad.

description: A rich of 3,4-seco-lupane triterpenoids (3,4-SLT), including chiisanoside (CSS), divaroside (DVS), sessiloside-A1 (SSA), chiisanogenin (CSG), sessiligenin (SSG), were isolated from the ethanol extract of the leaves of Eleutherococcus sessiliflorus (LES). The present study was performed to explore the cytotoxic and anti-tumor effects of the isolated five ones, as well as potential molecular mechanisms. The results of a CCK-8 assay demonstrated that these 3,4-SLT can inhibit the growth of HepG2 cells, and SSG showed the most significant cytotoxicity. Hoechst 33258 fluorescence staining and Annexin V-FITC/PI staining indicated that 3,4-SLT in LES can induce HepG2 cell apoptosis effectively. The AutoDock Vina program was used to simulate molecular docking of drugs and targets to discuss possible pharmacological mechanisms. Besides, western blot and qRT-PCR results indicated that SSG can inhibit PI3K/AKT signaling pathway through controlling multi-targets. This study suggested that 3,4-SLT might become a new research hotspot for antineoplastic drugs.

description: We detect Lyman $α$ absorption from the escaping atmosphere of HD 63433c, a $R=2.67 R_\oplus$, $P=20.5$ d mini Neptune orbiting a young (440 Myr) solar analogue in the Ursa Major Moving Group. Using HST/STIS, we measure a transit depth of $11.1 \pm 1.5$% in the blue wing and $8 \pm 3$% in the red. This signal is unlikely to be due to stellar variability, but should be confirmed by an upcoming second visit with HST. We do not detect Lyman $α$ absorption from the inner planet, a smaller $R=2.15 R_\oplus$ mini Neptune on a 7.1 d orbit. We use Keck/NIRSPEC to place an upper limit of 0.5% on helium absorption for both planets. We measure the host star's X-ray spectrum and FUV flux with XMM-Newton, and model the outflow from both planets using a 3D hydrodynamic code. This model provides a reasonable match to the light curve in the blue wing of the Lyman $α$ line and the helium non-detection for planet c, although it does not explain the tentative red wing absorption or reproduce the excess absorption spectrum in detail. Its predictions of strong Lyman $α$ and helium absorption from b are ruled out by the observations. This model predicts a much shorter mass loss timescale for planet b, suggesting that b and c are fundamentally different: while the latter still retains its hydrogen/helium envelope, the former has likely lost its primordial atmosphere.

description: Scott Edward Anderson is an emerging voice in Portuguese American literature, specifically belonging to “a very special group of writers from the Azorean diaspora.” (Anderson 6) He was born in Providence, Rhode Island, though he has Azorean ancestry. His latest work, Azorean Suite: A Poem of the Moment, was published in 2020 with Letras Lavadas publishing house, being a long bilingual poem in which the author attempts to retrieve his Azorean roots. This study will propose an analysis of Anderson’s poem, namely focusing on his relationship with his mixed heritage and on the way he embraces his Azorean identity which, for many years, was hidden from and within him. Furthermore, Azorean Suite has been recently published, thus this study aims to shed a light on a new poetry book hopefully opening paths for further research, namely in the field of Portuguese American literature.

description: We propose a novel cost aggregation network, called Cost Aggregation Transformers (CATs), to find dense correspondences between semantically similar images with additional challenges posed by large intra-class appearance and geometric variations. Cost aggregation is a highly important process in matching tasks, which the matching accuracy depends on the quality of its output. Compared to hand-crafted or CNN-based methods addressing the cost aggregation, in that either lacks robustness to severe deformations or inherit the limitation of CNNs that fail to discriminate incorrect matches due to limited receptive fields, CATs explore global consensus among initial correlation map with the help of some architectural designs that allow us to fully leverage self-attention mechanism. Specifically, we include appearance affinity modeling to aid the cost aggregation process in order to disambiguate the noisy initial correlation maps and propose multi-level aggregation to efficiently capture different semantics from hierarchical feature representations. We then combine with swapping self-attention technique and residual connections not only to enforce consistent matching but also to ease the learning process, which we find that these result in an apparent performance boost. We conduct experiments to demonstrate the effectiveness of the proposed model over the latest methods and provide extensive ablation studies.

description: The mean square atomic displacement in hcp-phase solid He-4 has been measured in crystals with a molar volume of 21.3 cm^3. It is temperature independent from 1 K to 140 mK, with no evidence for an anomaly in the vicinity of the proposed supersolid transition. The mean square displacement is different for in-plane motions (0.122 +/- 0.001 A^(2)) and out-of-plane motions (0.150 +/- 0.001 A ^(2)).

description: A new technique is presented for modifying the Einstein evolution equations off the constraint hypersurface. With this approach the evolution equations for the constraints can be specified freely. The equations of motion for the gravitational field variables are modified by the addition of terms that are linear and nonlocal in the constraints. These terms are obtained from solutions of the linearized Einstein constraints.

description: The theoretical interpretation of measurements of "wavefunctions" and spectra in electromagnetic cavities excited by antennas is considered. Assuming that the characteristic wavelength of the field inside the cavity is much larger than the radius of the antenna, we describe antennas as "point-like perturbations". This approach strongly simplifies the problem reducing the whole information on the antenna to four effective constants. In the framework of this approach we overcame the divergency of series of the phenomenological scattering theory and justify assumptions lying at the heart of "wavefunction measurements". This selfconsistent approach allowed us to go beyond the one-pole approximation, in particular, to treat the experiments with degenerated states. The central idea of the approach is to introduce ``renormalized'' Green function, which contains the information on boundary reflections and has no singularity inside the cavity.

description: We present a new radiative transfer method (SPH-M1RT) that is coupled dynamically with smoothed particle hydrodynamics (SPH). We implement it in the (task-based parallel) SWIFT galaxy simulation code but it can be straightforwardly implemented in other SPH codes. Our moment-based method simultaneously solves the radiation energy and flux equations in SPH, making it adaptive in space and time. We modify the M1 closure relation to stabilize radiation fronts in the optically thin limit. We also introduce anisotropic artificial viscosity and high-order artificial diffusion schemes, which allow the code to handle radiation transport accurately in both the optically thin and optically thick regimes. Non-equilibrium thermo-chemistry is solved using a semi-implicit sub-cycling technique. The computational cost of our method is independent of the number of sources and can be lowered further by using the reduced speed of light approximation. We demonstrate the robustness of our method by applying it to a set of standard tests from the cosmological radiative transfer comparison project of Iliev et al. The SPH-M1RT scheme is well-suited for modelling situations in which numerous sources emit ionising radiation, such as cosmological simulations of galaxy formation or simulations of the interstellar medium.

Deep Matching Prior: Test-Time Optimization for Dense Correspondence

description: Conventional techniques to establish dense correspondences across visually or semantically similar images focused on designing a task-specific matching prior, which is difficult to model. To overcome this, recent learning-based methods have attempted to learn a good matching prior within a model itself on large training data. The performance improvement was apparent, but the need for sufficient training data and intensive learning hinders their applicability. Moreover, using the fixed model at test time does not account for the fact that a pair of images may require their own prior, thus providing limited performance and poor generalization to unseen images. In this paper, we show that an image pair-specific prior can be captured by solely optimizing the untrained matching networks on an input pair of images. Tailored for such test-time optimization for dense correspondence, we present a residual matching network and a confidence-aware contrastive loss to guarantee a meaningful convergence. Experiments demonstrate that our framework, dubbed Deep Matching Prior (DMP), is competitive, or even outperforms, against the latest learning-based methods on several benchmarks for geometric matching and semantic matching, even though it requires neither large training data nor intensive learning. With the networks pre-trained, DMP attains state-of-the-art performance on all benchmarks.

description: L’esegesi dell’espressione «(giovani) di tromba marina» (Decameron IX 5.35), come riconosce Vittore Branca, «non è del tutto sicura». L’autore, dopo aver discusso le chiose correnti, riprende un’interpretazione minoritaria, quella di tromba marina come strumento musicale (Quarta Crusca e Grande Dizionario della Lingua Italiana), ma l’inquadra in una maniera del tutto nuova, mettendo a confronto, come il testo sembra richiedere, quello strumento con la ribeca di Calandrino. The exegesis of the expression «(giovani) di tromba marina», «(youth) of marine trumpet» (Decameron IX 5.35), as Vittore Branca acknowledged, «is not entirely sure». The author, after discussing the current glosses, takes up a minority interpretation, that of the «tromba marina» as a musical instrument (4th edition of the Crusca, Grande Dizionario della Lingua Italiana), but he frames the explanation in a quite new way, comparing, as the text seems to require, that instrument with Calandrino’s rebec.

description: This article aims to study the literary fortune of Virginia Woolf’s novel Orlando (1928) by analyzing two of its Portuguese translations. By that time the translator and poet Cecília Meireles published the first translation (1962), Portugal was living in the Estado Novo’s Regime, whose censorship power allowed editing or prohibiting literary publications in case these threatened the Dictatorship’s political, social or moral ideals. The second translation chosen as an object of study is Miguel Romeira’s translation of Orlando (2019), that offers the reader a visibly different approach from that of 1962 and which publication coincides with the national release of the film Vita Virginia (2019). The differentiating factor of these two translations lies on the choice of words used to address gender issues by both translators justifying the intentions behind each publication.

Casimir-Polder force density between an atom and a conducting wall

description: In this paper we calculate the Casimir-Polder force density (force per unit area acting on the elements of the surface) on a metallic plate placed in front of a neutral atom. To obtain the force density we use the quantum operator associated to the electromagnetic stress tensor. We explicitly show that the integral of this force density over the plate reproduces the total force acting on the plate. This result shows that, although the force is obtained as a sum of surface element-atom contributions, the stress-tensor method includes also nonadditive components of Casimir-Polder forces in the evaluation of the force acting on a macroscopic object.

Performance of the CMS muon trigger system in proton-proton collisions at $\sqrt{s} =$ 13 TeV

description: The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC achieved instantaneous luminosities as high as 2 $\times$ 10$^{34}$cm$^{-2}$s$^{-1}$ while delivering proton-proton collisions at $\sqrt{s} =$ 13 TeV. The challenge for the trigger system of the CMS experiment is to reduce the registered event rate from about 40 MHz to about 1 kHz. Significant improvements important for the success of the CMS physics program have been made to the muon trigger system via improved muon reconstruction and identification algorithms since the end of Run 1 and throughout the Run 2 data-taking period. The new algorithms maintain the acceptance of the muon triggers at the same or even lower rate throughout the data-taking period despite the increasing number of additional proton-proton interactions in each LHC bunch crossing. In this paper, the algorithms used in 2015 and 2016 and their improvements throughout 2017 and 2018 are described. Measurements of the CMS muon trigger performance for this data-taking period are presented, including efficiencies, transverse momentum resolution, trigger rates, and the purity of the selected muon sample. This paper focuses on the single- and double-muon triggers with the lowest sustainable transverse momentum thresholds used by CMS. The efficiency is measured in a transverse momentum range from 8 to several hundred GeV.

A Museum of Contemporary Architecture in new Yaletown, Vancouver

Publisher: name: University of British Columbia

description: This thesis project, a Museum of Contemporary Architecture in Vancouver, offers solu tions to architectural design problems resulting from the placement of an institutional use, the museum, within the social and physical framework of the city. The emphasis of this project is to integrate two polar opposites. On one hand resides the bureaucratic elite of a cultural institution: the curatorial machinery of contemporary architecture. On the other hand are the contradictory forces of the city: the wandering of the diverse population through the site, the intrusion of other uses within the body of the building, and the shifting of museum uses onto adjacent noninstitutional structures. The method of research has been through a three month iterative process of reading, draw ing and modelling, following consultation with the thesis committee. Represented here is the third version of the project, in it’s most resolved form. For a record of the thesis preparation, please see the design study, directed by Professor Sherry McKay, held in the Architecture Read ing Room. The conclusions of this thesis project resulted from aggressive reworkings. First, the uses of the building were interrogated and then condensed into their simplest form. This involved deleting most of the traditional museum functions. Libraries and bookstores, meeting rooms and cafes and staff offices were transplanted offsite or given away to other businesses. This allowed a new underground film room and night club to intrude in the basement, and an estranged office and residence to hover over the small exhibition spaces. Second, the massing of these uses needed separate identities. Finally, out of a desire for an open urban expression, the building mass was reduced further to introduce empty floors between uses, and a two meter setback between the building and the next structure on the block. Light and air, infiltrating these intersti tial spaces of the design, emanated towards the street. A concrete structure holds this composi tion together, with steel struts bracing against earthquake forces. A double row of street trees filter the resultant vision, layering the building in the urban context. The subject of this thesis was prompted by a comment by Thom Mayne’s during his visit to UBC in 1993. Mr. Mayne felt that the traditional scope of contemporary architecture could be improved, especially when contrasted to the breadth of issues in the fine arts. This project helped me to investigate the architectural possibilities of institutional expres sion in the urban core.
