Claudine et l’amour : roman d’amour « moyen » et modernité à la Belle Époque

Claudine i l’amor: novel·la d’amor “de segona fila” i modernitat durant la Belle Époque Durant aquest període de modernització ultrarràpida que fou la Belle Époque, la ficció va adquirir la seva funció cartogràfica respecte a la societat contemporània, en particular pel que feia a un públic lector de classe popular i mitjana. De cara a les burgeses aquella funció la duia a terme la novel·la d’amor de segona fila o “middlebrow”, subcategoria de la novel·la de costums tan apreciada entre el públic de 1900. A través de l’anàlisi d’una novel·la de Daniel Lesueur i de dues de les Claudine de Colette, publicades entre 1901 y 1903, aquest capítol intenta demostrar que ambdues novel·listes (como tantes altres contemporànies) van saber fer ús del pitjor dels gèneres per tal d’explorar i afirmar la posició contradictòria per bé que real de les dones a la modernitat del nou segle. Allà on Lesueur realitza una modulació subtil del gènere, Colette el reconfigura amb humor i valentia, tot i que les dues confirmen el poder subversiu d’un gènere sovint menystingut i qualificat d’insípid alhora que conservador

Middlebrow Matters

Middlebrow is a derogatory word that connotes blandness, mediocrity and a failed aspiration to ‘high’ culture. However, when appropriated as a positive term to denote that wide swathe of literature between the challenging experimentalism of the high and the formulaic drive of the popular, it enables a rethinking of the literary canon from the point of view of what most readers actually read, a criterion curiously absent from dominant definitions of literary value. Since women have long formed a majority of the nation’s reading public, this perspective immediately feminises what has always been a very male canon. Opening with a theorisation of the concept of middlebrow that mounts a defence of some literary qualities disdained by modernism, the book then focuses on a series of case studies of periods (the Belle Époque, inter-war, early twenty-first century), authors (including Colette, Irène Nemirovsky, Françoise Sagan, Anna Gavalda) and the middlebrow nature of literary prizes

Magic-State Functional Units: Mapping and Scheduling Multi-Level Distillation Circuits for Fault-Tolerant Quantum Architectures

Quantum computers have recently made great strides and are on a long-term path towards useful fault-tolerant computation. A dominant overhead in fault-tolerant quantum computation is the production of high-fidelity encoded qubits, called magic states, which enable reliable error-corrected computation. We present the first detailed designs of hardware functional units that implement space-time optimized magic-state factories for surface code error-corrected machines. Interactions among distant qubits require surface code braids (physical pathways on chip) which must be routed. Magic-state factories are circuits comprised of a complex set of braids that is more difficult to route than quantum circuits considered in previous work [1]. This paper explores the impact of scheduling techniques, such as gate reordering and qubit renaming, and we propose two novel mapping techniques: braid repulsion and dipole moment braid rotation. We combine these techniques with graph partitioning and community detection algorithms, and further introduce a stitching algorithm for mapping subgraphs onto a physical machine. Our results show a factor of 5.64 reduction in space-time volume compared to the best-known previous designs for magic-state factories.Comment: 13 pages, 10 figure

Resource Optimized Quantum Architectures for Surface Code Implementations of Magic-State Distillation

Quantum computers capable of solving classically intractable problems are under construction, and intermediate-scale devices are approaching completion. Current efforts to design large-scale devices require allocating immense resources to error correction, with the majority dedicated to the production of high-fidelity ancillary states known as magic-states. Leading techniques focus on dedicating a large, contiguous region of the processor as a single "magic-state distillation factory" responsible for meeting the magic-state demands of applications. In this work we design and analyze a set of optimized factory architectural layouts that divide a single factory into spatially distributed factories located throughout the processor. We find that distributed factory architectures minimize the space-time volume overhead imposed by distillation. Additionally, we find that the number of distributed components in each optimal configuration is sensitive to application characteristics and underlying physical device error rates. More specifically, we find that the rate at which T-gates are demanded by an application has a significant impact on the optimal distillation architecture. We develop an optimization procedure that discovers the optimal number of factory distillation rounds and number of output magic states per factory, as well as an overall system architecture that interacts with the factories. This yields between a 10x and 20x resource reduction compared to commonly accepted single factory designs. Performance is analyzed across representative application classes such as quantum simulation and quantum chemistry.Comment: 16 pages, 14 figure

Optimized Surface Code Communication in Superconducting Quantum Computers

Quantum computing (QC) is at the cusp of a revolution. Machines with 100 quantum bits (qubits) are anticipated to be operational by 2020 [googlemachine,gambetta2015building], and several-hundred-qubit machines are around the corner. Machines of this scale have the capacity to demonstrate quantum supremacy, the tipping point where QC is faster than the fastest classical alternative for a particular problem. Because error correction techniques will be central to QC and will be the most expensive component of quantum computation, choosing the lowest-overhead error correction scheme is critical to overall QC success. This paper evaluates two established quantum error correction codes---planar and double-defect surface codes---using a set of compilation, scheduling and network simulation tools. In considering scalable methods for optimizing both codes, we do so in the context of a full microarchitectural and compiler analysis. Contrary to previous predictions, we find that the simpler planar codes are sometimes more favorable for implementation on superconducting quantum computers, especially under conditions of high communication congestion.Comment: 14 pages, 9 figures, The 50th Annual IEEE/ACM International Symposium on Microarchitectur

Does Body Mass Index Influence the Physiological and Perceptual Demands Associated with Defensive Tactics Training in State Patrol Officers?

International Journal of Exercise Science 11(6): 319-330, 2018. The purpose of this investigation was to determine the physiological and perceptual demands associated with defensive tactics (DEFTAC) training among state patrol officers of different BMI (body mass index) categories. Twenty-four male state patrol officers (n = 24, age 36.00 + 7.86 yrs) voluntarily agreed to participate in data collection during a DEFTAC gauntlet. Anthropometric information (height (HT) 182.19 + 7.43 cm and weight (WT) 96.31 + 17.45 kg), body mass index (BMI), peak and average heart rates, duty weight, BLa, and RPE, were recorded. Officers were then divided into two-groups (Healthy BMI (BMI ≤ 25), n = 12, Overweight (BMI ≥ 25), n = 12). Analyses of covariance (ANCOVAs) were conducted to determine the effect of BMI on the outcome variables. Furthermore, a Pearson’s product-moment correlation coefficient was also conducted to determine if significant relationships between RPE, BLa, and HR existed between groups. Significant mean score differences between healthy and overweight officers were found in measures of age [t(22) 4.12, p\u3c 0.01, R2 = .44], and weight of duty gear [t(21) 3.96, p\u3c0.01, R2 = .33]. When used as a covariate, age also predicted average HR% [ F(1, 21) = 6.19, p \u3c .05, partial η2 = .24]. Significant relationships were found in the healthy group between RPE and DEFTAC time, DEFTAC time and score, as well as score and post BLa. Significant relationships for the overweight group between peak (HR) percentage and post BLa, peak (HR) percentage and RPE, DEFTAC time and duty weight, and between weight and DEFTAC time. The results of this study suggest that overweight officers may have lower DEFTAC scores when compared to their healthy counterparts. Based on the results, it seems reasonable to compare physiological variables from this population to those from combative sports as well as for officers to achieve and maintain a healthy BMI value in order to improve individual DEFTAC performance

Determinación del módulo de elasticidad para concretos estructurales utilizados en la ciudad de Santa Marta

Este proyecto pretende determinar el módulo de elasticidad para concretos estructurales utilizados en la ciudad de Santa Marta; este se desarrolla teniendo en cuenta los materiales con los que se están elaborando los concretos en la ciudad.El concreto, como muchos otros materiales estructurales, tiene algún grado de elasticidad. Como el concreto se utiliza principalmente en compresión su curva esfuerzo-deformación a compresión es de fundamental interés para la deducción de los valores o datos que se usan para calcular los elementos de concreto reforzado de una estructura. Esta curva se obtiene mediante mediciones adecuadas de las deformaciones en los ensayos depro betas cilíndricas, en los cuales durante el proceso de carga se van registrando las cargas y las deformaciones. De las cargas totales se obtienen los esfuerzos unitarios normales (carga/área) y puede así dibujarse la curva de los diferentes tipos de mezclas de las diversas concretéras que existen en Santa Marta. Esta investigación servirá para lograr en un futuro una unificación de criterios con respecto a este tema, para que las construcciones a realizaren la ciudad de Santa Marta posean un mismo índice del Módulo de Elasticidad de acuerdo al material (en este caso concreto) que se está utilizando, y así obtener cálculos más exactos y construcciones más seguras

SQUARE: Strategic Quantum Ancilla Reuse for Modular Quantum Programs via Cost-Effective Uncomputation

Compiling high-level quantum programs to machines that are size constrained (i.e. limited number of quantum bits) and time constrained (i.e. limited number of quantum operations) is challenging. In this paper, we present SQUARE (Strategic QUantum Ancilla REuse), a compilation infrastructure that tackles allocation and reclamation of scratch qubits (called ancilla) in modular quantum programs. At its core, SQUARE strategically performs uncomputation to create opportunities for qubit reuse. Current Noisy Intermediate-Scale Quantum (NISQ) computers and forward-looking Fault-Tolerant (FT) quantum computers have fundamentally different constraints such as data locality, instruction parallelism, and communication overhead. Our heuristic-based ancilla-reuse algorithm balances these considerations and fits computations into resource-constrained NISQ or FT quantum machines, throttling parallelism when necessary. To precisely capture the workload of a program, we propose an improved metric, the "active quantum volume," and use this metric to evaluate the effectiveness of our algorithm. Our results show that SQUARE improves the average success rate of NISQ applications by 1.47X. Surprisingly, the additional gates for uncomputation create ancilla with better locality, and result in substantially fewer swap gates and less gate noise overall. SQUARE also achieves an average reduction of 1.5X (and up to 9.6X) in active quantum volume for FT machines.Comment: 14 pages, 10 figure
