Serving Exoticism: The Black Female in French Exotic Imagery, 1733-1885
Creators: name: Childs, Adrienne L.
Publisher: name: Digital Repository at the University of Maryland
Year: 1999

description: The black female played an important part in the construction of
exotic female sexuality in French painting for nearly two hundred
years, yet her symbolic complexity has not been fully explored. This
thesis is a contextual analysis of the image of the black female in
French painting from the early part of the eighteenth through the
nineteenth century.
Representations of black females in this era are part of the
larger development of turquerie in the eighteenth century and
Orientalism in the nineteenth century. Centered around European
fantasies of Near Eastern and North African harem culture, turquerie
and Orientalism provided an exotic framework in which issues of
female sexuality and its relationship to race was explored. The objects
discussed in this thesis, primarily well known works by academic
painters, are examples of images in which the black female plays a
significant stylistic and ideological role.
The works are examined in relation to literary and scientific
discourses in which ideas about black women were negotiated during
the period. Slavery, imperialism, as well as colonial expansion
contextualize the imagery, and offer tools with which to uncover
encoded meanings inscribed in the exoticized black female.
This analysis provides an expanded definition of the nature of
the black female as a symbol, and outlines a complex, multidimensional
framework in which black female figures operate as a
sexual signifier.

description: Recenti test sul potenziale socio-cognitivo e il valore edonico di testi letterari che utilizzano elementi magici rivelano come la controfattualità costituisca una ‘palestra mentale’ per i lettori: essi apprendono a elaborare spiegazioni causali complesse e incrementano i fattori coinvolti nel costituirsi della coesione sociale, sia nel caso di lettori young adult sia nel caso di lettori adulti. Lo psicologo Eugene Subbotsky ha dimostrato che la magia ci rende più sensibili alle operazioni di Teoria della Mente e socialmente empatici, mentre un gruppo di narratologi ha di recente misurato i tempi di riassorbimento della dissonanza cognitiva prodotta dall'elemento magico: ciò riesce fra l'altro a spiegare il grande successo di Harry Potter e della saga di Twilight.

Recent tests on the social and cognitive potential and the hedonistic value of literary texts that use magic elements show how counterfactuality is a kind of ‘mental training’ for readers: they learn to formulate complex causal explanations and involve more factors in the constitution of social cohesion, both in the case of young adults and adult readers. The psychologist Eugene Subbotsky showed that magic makes us more sensitive to Theory of Mind acts and more socially empathic, and a group of narratologists recently measured the resolution time of cognitive dissonance induced by magical elements: this also explain the great success of the Harry Potter and Twilight sagas.

description: The transport and thermodynamic properties of $β$-ReO$_{2}$ crystallizing in a nonsymmorphic structure were studied using high-quality single crystals. An extremely large magnetoresistance (XMR) reaching 22,000 $\%$ in a transverse magnetic field of 10 T at 2 K was observed. However, distinguished from other topological semimetals with low carrier densities that show XMR, $β$-ReO$_{2}$ has a high electron carrier density of 1 $\times$ $10^{22}$ cm$^{-3}$ as determined by Hall measurements and large Fermi surfaces in the electronic structure. In addition, a small Fermi surface with a small effective mass was evidenced by de Haas-van Alphen oscillation measurements. The previous band structure calculations [S. S. Wang, et al., Nat. Commun. 8, 1844 (2017)] showed that two kinds of loops made of Dirac points of hourglass-shaped dispersions exist and are connected to each other by a point to form a string of alternating loops, called the Dirac loop chain (DLC), which are protected by the multiple glide symmetries. Our first-principles calculations revealed the complex Fermi surfaces with the smallest one corresponding to the observed small Fermi surface, which is just located near the DLC. The XMR of $β$-ReO$_{2}$ is attributed to the small Fermi surface and thus is likely caused by the DLC.

description: We give an infinite dimensional generalized Weierstrass representation for spacelike constant mean curvature (CMC) surfaces in Minkowski 3-space $\real^{2,1}$. The formulation is analogous to that given by Dorfmeister, Pedit and Wu for CMC surfaces in Euclidean space, replacing the group $SU_2$ with $SU_{1,1}$. The non-compactness of the latter group, however, means that the Iwasawa decomposition of the loop group, used to construct the surfaces, is not global. We prove that it is defined on an open dense subset, after doubling the size of the real form $SU_{1,1}$, and prove several results concerning the behavior of the surface as the boundary of this open set is encountered. We then use the generalized Weierstrass representation to create and classify new examples of spacelike CMC surfaces in $\real^{2,1}$. In particular, we classify surfaces of revolution and surfaces with screw motion symmetry, as well as studying another class of surfaces for which the metric is rotationally invariant.

Active galactic nuclei in four metal-poor dwarf emission-line galaxies

description: We present 3.5m Apache Point Observatory second-epoch spectra of four low-metallicity emission-line dwarf galaxies discovered serendipitously in the Data Release 5 of the Sloan Digital Sky Survey (SDSS) to have extraordinary large broad Halpha luminosities, ranging from 3x10^41 to 2x10^42 erg/s. The oxygen abundance in these galaxies is very low, varying in the range 12+logO/H = 7.36- 7.99. Such extraordinarily high broad Halpha luminosities cannot be accounted for by massive stars at different stages of their evolution. By comparing with the first-epoch SDSS spectra, we find that the broad Halpha luminosities have remained constant over a period of 3-7 years, which probably excludes type IIn supernovae as a possible mechanism of broad emission. The emission most likely comes from accretion disks around intermediate-mass black holes with lower mass limits in the range ~5x10^5 Msun-3x10^6 Msun. If so, these four objects form a new class of very low-metallicity AGN that have been elusive until now. The absence of the strong high-ionization lines [NeV] 3426 and He II 4686 can be understood if the nonthermal radiation contributes less than ~10% of the total ionizing radiation.

Japan's government and steel industry policies towards coking coal procurement : the implications of industrial restructuring for the northeast coal project
Creators: name: Catliff, Christopher Edward
Publisher: name: University of British Columbia
Year: 2010

description: Japan's recent economic success or what has often been termed "the Japanese Miracle" has been a result of perceptive industrial policies and import and export strategies pursued by both government and industry together. Bilateral trade surpluses have brought about allegations from trading partners that Japan's trading practices are "unfair". While this study does not explicitly examine such a broad and subjective accusation, it does analyse distinct Japanese policies in the context of the steel industry and its overseas procurement of coking coal for steel production. The case of Japan's last major overseas coal venture, the Northeast Coal Project, is presented to provide answers to four questions which form the basic themes of the paper. How do the Japanese seek secure supplies of coking coal? Do the Japanese seek lower prices by encouraging excess supply? What conditions affecting coal demand have changed since January 1981 when the coal contracts were signed? Finally, will the Japanese abide by the terms of these contracts they signed in 1981? Through a focus on the process and substance of Japanese coal procurement policy, its application in the case of northeast coal, and its response to unexpectedly adverse market conditions, five propositions are developed. First, Japan persuades foreigners to commit themselves to the development and export of resources through quasi-integration. Second, the government and firms within the steel sector coordinate all procurement of coking coal. Third, Japan will pay a premium to ensure security of its coal supply. Fourth, structural shifts within the Japanese economy and changing world market conditions will cause a lower demand for coking coal than forecast; and finally, the Japanese will not break existing contracts if they perceive that that will undermine their access to resources and export markets.
Continuum and all-atom description of the energetics of graphene nanocones

Year: 2007
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Energies of graphene nanocones with 1 to 5 pentagonal disclinations are studied on an atomically detailed level. The numerical results are interpreted in terms of three different contributions to the cone energy: the core disclination energy, the bending energy of the cone surface, and the ''line tension'' energy of the cone edge that is related to different coordination of carbon atoms situated at the edge. This continuum description allows for a construction of analytic expressions for the cone energetics and indicates different regimes of cone sizes in which cones with a particular number of disclinations are preferred energywise. An important result of the study is that the energetics of various types of cones profoundly depends upon whether the dangling carbon bonds at the cone basis are saturated by hydrogen atoms or not. This may be of use for explaining the differences in the yields of various cone types in different production processes.

description: Cells within living soft biological tissues seem to promote the maintenance of a mechanical state within a defined range near a so-called set-point. This mechanobiological process is often referred to as mechanical homeostasis. During this process, cells intimately interact with the fibers of the surrounding extracellular matrix (ECM). It remains poorly understood, however, what individual cells actually regulate during these interactions, and how these micromechanical regulations are translated to tissue level to lead to what we macroscopically call mechanical homeostasis. Herein, we examine this question by a combination of experiments, theoretical analysis and computational modeling. We demonstrate that on short time scales (hours) - during which deposition and degradation of ECM fibers can largely be neglected - cells appear to regulate neither the stress / strain in the ECM nor their own shape, but rather only the contractile forces that they exert on the surrounding ECM.

description: Recent Spitzer observations have revealed a substantial population of z~2 ULIRGs with deep silicate absorption (τ_{9.7}>1). This paper reports a 20cm radio study of such a sample to elucidate their physical nature. We discover that a substantial fraction (40%) of deep silicate absorption ULIRGs at z~2 are moderately radio-loud with L_{1.4GHz}=10^{25}--10^{26}WHz^{-1}. This is in strong contrast with z<1 radio galaxies and radio-loud quasars where none of the sources with available IRS spectra have τ_{9.7}>1. In addition, we observe radio jets in two of our sources where one has a double lobe structure ~200kpc in extent, and another shows a one-sided jet extending ~90kpc from the nucleus. The likely high inclination of the latter, coupled with its deep silicate absorption, implies the mid-IR obscuration does not share an axis with the radio jets. These sources are highly obscured quasars, observed in the transition stage after the birth of the radio source, but before feedback effects dispel the ISM and halt the black hole accretion and starburst activity.

description: A shift-invariant space is a space of functions that is invariant under integer translations. Such spaces are often used as models for spaces of signals and images in mathematical and engineering applications. This paper characterizes those shift-invariant subspaces S that are also invariant under additional (non-integer) translations. For the case of finitely generated spaces, these spaces are characterized in terms of the generators of the space. As a consequence, it is shown that principal shift-invariant spaces with a compactly supported generator cannot be invariant under any non-integer translations.

description: The Modboat is an autonomous surface robot that turns the oscillation of a single motor into a controlled paddling motion through passive flippers. Inertial control methods developed in prior work can successfully drive the Modboat along trajectories and enable docking to neighboring modules, but have a non-constant cycle time and cannot react to dynamic environments. In this work we present a thrust direction control method for the Modboat that significantly improves the time-response of the system and increases the accuracy with which it can be controlled. We experimentally demonstrate that this method can be used to perform more compact maneuvers than prior methods or comparable robots can. We also present an extension to the controller that solves the reaction wheel problem of unbounded actuator velocity, and show that it further improves performance.

description: A near-infrared (NIR) enhanced silicon single-photon avalanche diode (SPAD) fabricated in a customized 0.13 $μ$m CMOS technology is presented. The SPAD has a depleted absorption volume of approximately 15 $μ$m x 15 $μ$m x 18 $μ$m. Electrons generated in the absorption region are efficiently transported by drift to a central active avalanche region with a diameter of 2 $μ$m. At the operating voltage, the active region contains a spherically uniform field peak, enabling the multiplication of electrons originating from all corners of the device. The advantages of the SPAD architecture include high NIR photon detection efficiency (PDE), drift-based transport, low afterpulsing, and compatibility with an integrated CMOS readout. A front-side illuminated device is fabricated and characterized. The SPAD has a PDE of 13% at wavelength 905 nm, an afterpulsing probability < 0.1% for a dead time of 13 ns, and a median dark count rate (DCR) of 840 Hz at room temperature. The device shows promising performance for time-of-flight applications that benefit from uniform NIR-sensitive SPAD arrays.

Testing the AGB Scenario as the Origin of the Extreme-Helium Population in omega Centauri

Publisher: name: arXiv
Year: 2008

description: The most massive Galactic globular cluster, Omega centauri, appears to have multiple populations. Its bluest main sequence and extended horizontal branch stars are suggested to have the common origin, that is, an extremely high helium abundance of Y ~ 0.4. The high helium abundance is most often attributed to asymptotic giant branch (AGB) stars. In this study we test the AGB hypothesis. We simulate the maximum-AGB models where the impact of AGB stars is maximised by assuming that supernova explosions do not affect the chemical evolution of the proto cloud. We compare the enrichment history of helium, metals, carbon and nitrogen to the observed values. Even under the most generous condition, the maximum-AGB models fail to reproduce the large values of helium Y ~ 0.4 and helium enrichment parameter Delta Y / Delta Z ~ 70 which were deduced from the colour-magnitude diagram fits. They also fail to reproduce the C and N contents of the blue population spectroscopically determined. We conclude that the AGB scenario with the canonical stellar evolution theory cannot explain the observational constraints and that the self chemical enrichment does not provide a viable solution. Alternative processes are desperately called for.

description: To clarify the order parameter symmetry of cuprates, the magnetic penetration depth $λ$ was measured along the crystallographic directions $a$, $b$, and $c$ in single crystals of YBa$_2$Cu$_4$O$_8$ via muon spin rotation. This method is direct, bulk sensitive, and unambiguous. The temperature dependences of $λ_a^{-2}$ and $λ_b^{-2}$ exhibit an inflection point at low temperatures as is typical for two-gap superconductivity (TGS) with $s+d-$wave character in the planes. Perpendicular to the planes a pure s-wave gap is observed thereby highlighting the important role of c-axis effects. We conclude that these are generic and universal features in the bulk of cuprates.

description: There is no unique way to quantify the degree of delocalization of quantum states in unbounded continuous spaces. In this work, we explore a recently introduced localization measure that quantifies the portion of the classical phase space occupied by a quantum state. The measure is based on the $α$-moments of the Husimi function and is known as the Rényi occupation of order $α$. With this quantity and random pure states, we find a general expression to identify states that are maximally delocalized in phase space. Using this expression and the Dicke model, which is an interacting spin-boson model with an unbounded four-dimensional phase space, we show that the Rényi occupations with $α>1$ are highly effective at revealing quantum scars. Furthermore, by analyzing the high moments ($α>1$) of the Husimi function, we are able to identify qualitatively and quantitatively the unstable periodic orbits that scar some of the eigenstates of the model.

Expressive photography : on the need for a cross-disciplinary approach to the study of photographics
Creators: name: Emme, Michael John
Publisher: name: University of British Columbia
Year: 2010

description: The thesis is proposed that an orderly understanding of the expressive capacities of Photography can be drawn from a survey of the disciplines of art history, art criticism, psychology, sociology, and anthropology as well as the field of photo-technology. Photography is defined as including five elements: the camera, the photographer, the subject, the image and the viewer. Topics considered are: the camera's mechanical limitations and qualities; the various behaviours and attitudes involved in picture-taking; the considerations involved in subject choice; the limitations and qualities of expression of the photographic print; and role of the viewer. It is posited that the disciplines and fields listed above have a valuable addition to make toward our understanding of expressive photography. It is proposed that future courses in photography, whether they be intended for elementary school, high school, art school, or teacher training, include a cross-disciplinary approach. Such an approach can be incorporated into the curriculum through the use of the behavioural-attitudinal model introduced in Chapter III. Whether a course is weighted toward studio experience, history and criticism, or cultural education, using a cross-disciplinary approach will enrich the learning experience.

description: We study the spin-valley Kondo effect of a silicon quantum dot occupied by $% \mathcal{N}$ electrons, with $\mathcal{N}$ up to four. We show that the Kondo resonance appears in the $\mathcal{N}=1,2,3$ Coulomb blockade regimes, but not in the $\mathcal{N}=4$ one, in contrast to the spin-1/2 Kondo effect, which only occurs at $\mathcal{N}=$ odd. Assuming large orbital level spacings, the energy states of the dot can be simply characterized by fourfold spin-valley degrees of freedom. The density of states (DOS) is obtained as a function of temperature and applied magnetic field using a finite-U equation-of-motion approach. The structure in the DOS can be detected in transport experiments. The Kondo resonance is split by the Zeeman splitting and valley splitting for double- and triple-electron Si dots, in a similar fashion to single-electron ones. The peak structure and splitting patterns are much richer for the spin-valley Kondo effect than for the pure spin Kondo effect.

description: In this work we investigate knowledge acquisition as performed by multiple agents interacting as they infer, under the presence of observation errors, respective models of a complex system. We focus the specific case in which, at each time step, each agent takes into account its current observation as well as the average of the models of its neighbors. The agents are connected by a network of interaction of Erdős-Renyi or Barabasi-Albert type. First we investigate situations in which one of the agents has a different probability of observation error (higher or lower). It is shown that the influence of this special agent over the quality of the models inferred by the rest of the network can be substantial, varying linearly with the respective degree of the agent with different estimation error. In case the degree of this agent is taken as a respective fitness parameter, the effect of the different estimation error is even more pronounced, becoming superlinear. To complement our analysis, we provide the analytical solution of the overall behavior of the system. We also investigate the knowledge acquisition dynamic when the agents are grouped into communities. We verify that the inclusion of edges between agents (within a community) having higher probability of observation error promotes the loss of quality in the estimation of the agents in the other communities.

description: We present electron temperature ($T_e$) maps for the edge-on system Mrk 1486, affording "direct-method" gas-phase metallicity measurements across $5.\!\!^{\prime\prime}8$ (4.1 kpc) along the minor axis and $9.\!\!^{\prime\prime}9$ (6.9 kpc) along the major axis. These maps, enabled by strong detections of the [OIII]$λ$4363 auroral emission line across a large spatial extent of Mrk 1486, reveal a clear negative minor axis $T_e$ gradient in which temperature decreases with increasing distance from the disk plane. We find that the lowest metallicity spaxels lie near the extremes of the major axis, while the highest metallicity spaxels lie at large spatial offsets along the minor axis. This is consistent with a picture in which low metallicity inflows dilute the metallicity at the edges of the major axis of the disk, while star formation drives metal-enriched outflows along the minor axis. We find that the outflow metallicity in Mrk 1486 is 0.20 dex (1.6 times) higher than the average ISM metallicity, and more than 0.80 dex (6.3 times) higher than metal-poor inflowing gas, which we observe to be below 5 % $Z_\odot$. This is the first example of metallicity measurements made simultaneously for inflowing, outflowing, and inner disk ISM gas using consistent $T_e$-based methodology. These measurements provide unique insight into how baryon cycle processes contribute to the assembly of a galaxy like Mrk 1486.

description: Surface treatments are designed to promote modified implant surfaces with positive interactions with the surrounding living tissues. However, the inadvertent early contact of these surfaces with oral fluids during surgery may lead to undesired conditions affecting osseointegration. This study aimed to investigate the possible alterations in the physico-chemical properties of modified-surfaces caused by early saliva exposure. Titanium (Ti) surfaces were exposed to three different samples of human saliva and later analyzed for protein adhesion, physico-chemical surface alterations, and osteogenic cell-viability. The results indicated that surface roughness was the most significant factor influencing saliva protein adsorption; moreover, hydrophilic surfaces had critically lost their characteristics after contact with saliva. Decreased cell viability was observed in cultures after contact with saliva. Early contact with saliva might negatively influence modified surface properties and local cell viability. Careful surgical insertion of implants with hydrophilic surfaces is recommended, particularly in sites where saliva interaction is prone to occur.

description: The Braess paradox is a counter-intuitive phenomenon whereby adding roads to a network results in higher travel time at equilibrium. In this paper we present an algorithm to detect the occurrence of this paradox in real-world networks with the help of an improved graph representation accounting for queues. The addition of queues to the network representation enables a closer match with real data. Moreover, we search for routes causing this phenomenon ("Braess routes") rather than links, and advocate removing such routes virtually from navigation systems so that the associated links can continue to serve other routes. Our algorithm relies on a convex optimization problem utilizing Beckmann potentials for road links as well as queues, and results in a route reconfiguration with reduced delay. We assume the availability of historical data to build the optimization model. We also assume the existence of a centralized navigation system to manage the routing options and remove the Braess routes. The theoretical solution demonstrates up to 12% delay reduction in a network from Montgomery County, Maryland. We validate the improvement with simulations.

description: Emerging analog resistive random access memory (RRAM) based on HfOx is an attractive device for non-von Neumann neuromorphic computing systems. The differences in temperature dependent conductance drift among cells hamper computing accuracy, characterized by the statistical distribution of temperature coefficient(Tα). A compact model was presented in order to investigate the statistical distribution of Tα under different resistance states. Based on this model, the physical mechanism of thermal instability of cells with a positive Tα was elucidated. Furthermore, this model can also effectively evaluate the impact of conductance distribution of different levels under various temperatures in artificial neural networks (ANN). An approach incorporating the optimized conductance range selection and the current compensation scheme was proposed to reduce the impacts of the distribution of Tα. The simulation results showed that recognition accuracy was improved from 79.8% to 89.6% for the application of MNIST handwriting digits classification with a two-layer perceptron at 400K after adopting the proposed optimization method.

description: The elementary processes taking place in the formation of charged particles and their flow in parallel-plane, cylindrical and spherical ionization chambers are considered. On the basis of particles and charges balance a differential equation describing the distribution of current densities in the ionization chamber volume is obtained. As a result of the differential equation solution an analytical form of the current-voltage characteristic of an ionization chamber with homogeneous ionization is obtained. For the parallel-plane case the comparison with experimental data is performed.

description: In this contribution, we predict the wellhead protection area (WHPA, target), the shape and extent of which is influenced by the distribution of hydraulic conductivity (K), from a small number of tracing experiments (predictor). Our first objective is to make stochastic predictions of the WHPA within the Bayesian Evidential Learning (BEL) framework, which aims to find a direct relationship between predictor and target using machine learning. This relationship is learned from a small set of training models (400) sampled from the prior distribution of K. The associated 400 pairs of simulated predictors and targets are obtained through forward modelling. Newly collected field data can then be directly used to predict the approximate posterior distribution of the corresponding WHPA. The uncertainty range of the posterior WHPA distribution is affected by the number and position of data sources (injection wells). Our second objective is to extend BEL to identify the optimal design of data source locations that minimizes the posterior uncertainty of the WHPA. This can be done explicitly, without averaging or approximating because once trained, the BEL model allows the computation of the posterior uncertainty corresponding to any new input data. We use the Modified Hausdorff Distance and the Structural Similarity index metrics to estimate the posterior uncertainty range of the WHPA. Increasing the number of injection wells effectively reduces the derived posterior WHPA uncertainty. Our approach can also estimate which injection wells are more informative than others, as validated through a k-fold cross-validation procedure. Overall, the application of BEL to experimental design makes it possible to identify the data sources maximizing the information content of any measurement data.

description: The global rise in antimicrobial resistance and lack of discovery of new antimicrobials have created serious concerns. Targeting quorum sensing (QS) and biofilms of pathogenic bacteria is considered a promising approach in antimicrobial drug discovery. This study explored the inhibitory effect of plumbagin against biofilms and QS of Chromobacterium violaceum, Serratia marcescens and Pseudomonas aeruginosa. Violacein production in C. violaceum 12472 was reduced by >80%. The virulent traits of P. aeruginosa PAO1 such as pyocyanin, rhamnolipid and proteases were also inhibited at sub-minimum inhibitory concentrations. Moreover, the biofilms of the test bacteria were reduced by 56–70%. Plumbagin reduced the bacterial adherence and colonization on solid surface. Computational studies gave closer insights regarding the possible modes of action. Molecular dynamics simulations revealed that the protein complexes were quite stable under physiological conditions. This study provides both experimental and computational evidence regarding the efficacy of plumbagin against biofilms and the QS-controlled virulence factors of Gram-negative bacteria.
Quantum state preparation protocol for encoding classical data into the amplitudes of a quantum information processing register's wave function
Creators: name: Ashhab, Sahel

Subjects: subject: Quantum Physics (quant-ph)

description: We present a protocol for encoding $N$ real numbers stored in $N$ memory registers into the amplitudes of the quantum superposition that describes the state of $\log_2N$ qubits. This task is one of the main steps in quantum machine learning algorithms applied to classical data. The protocol combines partial CNOT gate rotations with probabilistic projection onto the desired state. The number of additional ancilla qubits used during the implementation of the protocol, as well as the number of quantum gates, scale linearly with the number of qubits in the processing register and hence logarithmically with $N$. The average time needed to successfully perform the encoding scales logarithmically with the number of qubits, in addition to being inversely proportional to the acceptable error in the encoded amplitudes. It also depends on the structure of the data set in such a way that the protocol is most efficient for non-sparse data.

description: Quantum extremal surfaces are central to the connection between quantum information theory and quantum gravity and they have played a prominent role in the recent progress on the information paradox. We initiate a program to systematically link these surfaces to the microscopic data of the dual conformal field theory, namely the scaling dimensions of local operators and their OPE coefficients. We consider CFT states obtained by acting on the vacuum with single-trace operators, which are dual to one-particle states of the bulk theory. Focusing on AdS$_3$/CFT$_2$, we compute the CFT entanglement entropy to second order in the large $c$ expansion where quantum extremality becomes important and match it to the expectation value of the bulk area operator. We show that to this order, the Virasoro identity block contributes solely to the area operator.
