title: Louise Labé : sodalité expansive et individualité singulière, la formation d’une autorité poétique (féminine)
Creators: name: Snelling, Rosemary
Publisher: name: Savoirs en prisme
Year: 2020

description: L’article présent traite le processus textuel de la constitution d’autorité poétique dans l’œuvre de Louise Labé, la plus fameuse représentante du pétrarquisme féminin en France. S’insérant dans la pratique poétique de la première modernité, elle fait recours à des traditions littéraires, telles le pétrarquisme italien féminin et l’élégie antique, afin de se procurer de la gloire en surpassant ses prédécesseurs. La gloire, éperon plus fort des auteurs à cette époque-là, est étroitement liée à une mise-en-scène décisive de l’auteur dans le propre œuvre, soulignant aussi bien l’excellence singulière de l’auteur que l’inscription dans une communauté sociale et culturelle. En exploitant ces deux dispositifs fonctionnels, la soi-dite « singularisation » et le complément de la « sodalisation », l’article cherche à élucider soit le self-fashioning de Louise Labé comme grande amante, singulièrement accablée par un amour passionné, que son objectif de s’installer comme autorité acclamée non seulement parmi les femmes, mais aussi parmi les gens savants et les nobles en général. En fin de compte, l’emphase du for intérieur de cette auteure surpasse les limites des traditions littéraires et aboutit à une forme d’individualité psychique quasi-moderne, ce qui sera fondamental pour le succès et la gloire de Louise Labé au travers des siècles.

Halo properties and secular evolution in barred galaxies
Creators: name: Athanassoula, E.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The halo plays a crucial role in the evolution of barred galaxies. Its near-resonant material absorbs angular momentum emitted from some of the disc particles and helps the bar become stronger. As a result, a bar (oval) forms in the inner parts of the halo of strongly barred disc galaxies. It is thinner in the inner parts (but still considerably fatter than the disc bar) and tends to spherical at larger radii. Its length increases with time, while always staying shorter than the disc bar. It is roughly aligned with the disc bar, which it trails only slightly, and it turns with roughly the same pattern speed. The bi-symmetric component of the halo density continues well outside the halo bar, where it clearly trails behind the disc bar. The length and strength of the disc and halo bars correlate; the former being always much stronger than the latter. If the halo is composed of weakly interacting massive particles, then the formation of the halo bar, by redistributing the matter in the halo and changing its shape, could influence the expected annihilation signal. This is indeed found to be the case if the halo has a core, but not if it has a steep cusp. The formation and evolution of the bar strongly affect the halo orbits. A fraction of them becomes near-resonant, similar to the disc near-resonant orbits at the same resonance, while another fraction becomes chaotic. Finally, a massive and responsive halo makes it harder for a central mass concentration to destroy the disc bar.

description: We consider entanglement distillation with noisy operations in which quantum measurements that constitute a general quantum operation are particularly noisy. We present a protocol for purifying noisy measurements and show that imperfect local operations can distill entanglement. The protocol works for arbitrary noisy measurements in general and is cost-effective and resource-efficient with single additional qubit per party to resolve the distillation of entanglement. The purification protocol is feasible with currently available quantum technologies and readily applied to entanglement applications.

description: A survey on food consumption patterns was conducted in an urban black community and a rural black community. Urban consumers tend to consume more bread, and less maize meal than rural consumers. Urban consumers consume more meat than poverty-stricken rural dwellers. The same is true with respect to fruit and ready-made foods. Both quality and price are important considerations for consumers' food purchases, particularly rural consumers. Price appears to be less important to the higher income (> R2000 per month) consumers in purchases of bread and meat, but rather important in vegetable purchases. Almost 60 per cent never consume food at away from home food establishments.

description: We present a method relying on shortcuts to adiabaticity to achieve quantum detection of high frequency signals at the nanoscale in a robust manner. More specifically, our protocol delivers tailored amplitudes and frequencies for control fields that, firstly, enable the coupling of the sensor with high-frequency signals and, secondly, minimise errors that would otherwise spoil the detection process. To exemplify the method, we particularise to detection of signals emitted by fast-rotating nuclear spins with nitrogen vacancy center quantum sensors. However, our protocol is straightforwardly applicable to other quantum devices such as silicon vacancy centers, germanium vacancy centers, or divacancies in silicon carbide.

description: Nature doesn’t seem reducible to rigid systems and classifications. Although resorting to metaphors may give rise to contradictions, it allows the elaboration of explanatory models which help us to organize thought and to find orientation in the natural world. Giving form through metaphors stands for seeking the way by which mankind looks for both solutions and new configurations to face nature’s enigmas. The creation of morphological and/or evolutionary metaphors framed in a schematic way what Hugo called “man’s groping in the universe of nature”. Circles, arrows, spirals, scales, etc. stood for research directions: for example, scale became metaphor of an “animal universe” that – as it was thought to be in the Eighteenth Century – organized itself in a bottom-up scale. The circle referred to “metamorphosis” (Alle Glieder bilden sich aus nach ew'gen Gesetzen, /Und die seltenste Form bewahrt im Geheimen das Urbild), which reminds us of Goethe’s thinking. Metaphors are never an aim in themselves: they always determine a way of thinking as well as choices and research directions. Such a use of the linguistic image deeply influences the very notion of metaphor as figures of speech. If, on the one hand, metaphor shows unknown structures of nature, on the other it rediscovers its own ‘naturalness’. Starting from the deep interconnection between functional and formal tasks in morphological discussion, metaphor turned from “figure” to “figuration”, Gestaltung, and in doing so it revealed a dynamic structure able to make us understand new links and directions in the sense of a metamorphic nature. Far from limiting itself to a historical retrospection, the methodological significance of having recourse to metaphor profoundly informs the most recent questions in the scientific field and notably in life sciences, in the very moment in which it leads and encourages a renewed dialogue between sciences and philosophy.

Effect of cooling rate on solidification characteristics of aluminum alloys A356 and AA5182
Creators: name: Thompson, Stephanie
Publisher: name: University of British Columbia
Year: 2009

description: Microstructural reactions during solidification of aluminum alloys A356 (unmodified and strontium modified) and AA5182 were analyzed using cooling curve analysis to determine the evolution in fraction solid. The experiments involved recording the temperature/time data under different cooling rates so that the various phase changes associated with solidification could be identified. Once collected, the cooling curve data was processed to calculate the first derivative together with a baseline cooling curve (cooling curve in the absence of any transformations). Comparison of the baseline cooling curve to the first derivative data allowed accurate identification of start temperatures of the various liquid to solid transformations and characterization of fraction solid formed during the cooling process. In A356, strontium modification altered the morphology, decreased the solidification start temperature of new phases (2°C to 11°C) and increased solid fraction of the beginning of eutectic solidification and Mg2Si precipitation (0.01 to 0.05). For the conditions studied, cooling rate appeared to show no effect on fraction solid evolution but an increase in cooling rate reduced solidus temperature (48°C to 75°C), resulting in a larger freezing range. In AA5182 the main eutectic reaction and subsequent reactions, including Mg2Si formation, occurred at much lower temperatures and higher fraction solids than previously published. The primary eutectic was found to begin solidifying between 575- 588°C, which corresponds to a solid fraction between 0.87-0.91 and Mg2Si was found to precipitate between 551-560°C, which corresponds to a fraction solid between 0.96-0.97. Increasing cooling rate from 0.5°C/s to 2°C/s was observed to result in a slight increase in fraction solid for primary eutectic transformation from 0.87-0.88 at the low cooling rate to 0.89-0.91 at the intermediate cooling rate and 0.91 at the highest cooling rate. The highest cooling rate also resulted in a drop in solidus temperature to 461°C from 500- 510°C at the low and intermediate cooling rates. This led to an increase in the solidification interval from 123°C to 151°C.

description: We introduce and solve the one-dimensional quantum non-linear Schrodinger (NLS) equation for an N-component field defined on the real line with a defect sitting at the origin. The quantum solution is constructed using the quantum inverse scattering method based on the concept of Reflection-Transmission (RT) algebras recently introduced. The symmetry of the model is generated by the reflection and transmission defect generators defining a defect subalgebra. We classify all the corresponding reflection and transmission matrices. This provides the possible boundary conditions obeyed by the canonical field and we compute these boundary conditions explicitly. Finally, we exhibit a phenomenon of spontaneous symmetry breaking induced by the defect and identify the unbroken generators as well as the exact remaining symmetry.

description: We study the impact of mandatory calorie posting on consumers’ purchase decisions, using detailed data from Starbucks. We find that average calories per transaction falls by 6%. The effect is almost entirely related to changes in consumers’ food choices—there is almost no change in purchases of beverage calories. There is no impact on Starbucks profit on average, and for the subset of stores located close to their competitor Dunkin Donuts, the effect of calorie posting is actually to increase Starbucks revenue. Survey evidence and analysis of commuters suggest the mechanism for the effect is a combination of learning and salience.

description: Computing has become ubiquitous and organic. The “new” human ecosystem is increasingly composed of "intelligent" objects. Since the Nineties there has been a constant application of the practice of disappearance of everyday objects. The daily experience changes, since the objects we use, in their disappearance and imperceptibility, do not divide us from the Life-World. At the same time, the designer is called to rewrite and amplify human experience, and design reflects a different conception of the aesthetic, which must be intended not only as a theory of the artistic and/or cosmetic beauty, but mainly as a science of the experience as such. The designer is no longer limited to designing objects, but he can also design human beings.

description: This paper presents low-complexity block-based encoding and decoding algorithms for short block length channels. In terms of the precise use-case, we are primarily concerned with the baseline 3GPP Short block transmissions in which payloads are encoded by Reed-Muller codes and paired with orthogonal DMRS. In contemporary communication systems, the short block decoding often employs the utilization of DMRS-based least squares channel estimation, followed by maximum likelihood decoding. However, this methodology can incur substantial computational complexity when processing long bit length codes. We propose an innovative approach to tackle this challenge by introducing the principle of block/segment encoding using First-Order RM Codes which is amenable to low-cost decoding through block-based fast Hadamard transforms. The Block-based FHT has demonstrated to be cost-efficient with regards to decoding time, as it evolves from quadric to quasi-linear complexity with a manageable decline in performance. Additionally, by incorporating an adaptive DMRS/data power adjustment technique, we can bridge/reduce the performance gap and attain high sensitivity, leading to a good trade-off between performance and complexity to efficiently handle small payloads.

Thermodynamically consistent equation of state for an accreted neutron star crust

description: We study equation of state (EOS) of an accreting neutron star crust. Usually, such EOS is obtained assuming (implicitly) that the free (unbound) neutrons and nuclei in the inner crust move together. We argue, that this assumption violates the condition $μ_n^\infty={\rm const}$, required for hydrostatic (and diffusion) equilibrium of unbound neutrons ($μ^\infty_n$ is the redshifted neutron chemical potential). We construct a new EOS respecting this condition, working in the compressible liquid-drop approximation. We demonstrate that it is close to the catalyzed EOS in most part of the inner crust, being very different from EOSs of accreted crust discussed in the literature. In particular, the pressure at the outer-inner crust interface does not coincide with the neutron drip pressure, usually calculated in the literature, and is determined by hydrostatic (and diffusion) equilibrium conditions within the star. We also find an instability at the bottom of fully accreted crust that transforms nuclei into homogeneous nuclear matter. It guarantees that the structure of fully accreted crust remains self-similar during accretion.

description: Detector control systems (DCS) include the read out, control and supervision of hardware devices as well as the monitoring of external systems like cooling system and the processing of control data. The implementation of such a system in the final experiment has also to provide the communication with the trigger and data acquisition system (TDAQ). In addition, conditions data which describe the status of the pixel detector modules and their environment must be logged and stored in a common LHC wide database system. At the combined test beam all ATLAS subdetectors were operated together for the first time over a longer period. To ensure the functionality of the pixel detector a control system was set up. We describe the architecture chosen for the pixel detector control system, the interfaces to hardware devices, the interfaces to the users and the performance of our system. The embedding of the DCS in the common infrastructure of the combined test beam and also its communication with surrounding systems will be discussed in some detail.

description: The elimination of the quota program in 2002 reduced the barrier to entry into the peanut shelling industry. Peanut producers have expressed interest in integrating up to peanut shelling and marketing their own peanuts to peanut manufacturers. The peanut shelling and manufacturing sectors are concentrated, with little information available related to shelling costs and manufacturer purchasing characteristics for peanuts. A peanut buyer survey was conducted to gauge the willingness of buyers to purchase peanuts from a new player in the market and to identify what characteristics are important to buyers. The results indicate buyers are satisfied with current suppliers. However, buyers use more than one supplier and are open to new suppliers in the market.

description: The evolution of Interaction Design could be read as a radicalization of the dogma of modern functionalism, Less is More, and a "rediscovery" of certain theories of Minimal Art. This radicalization is reflected in the same evolution that has taken place since the early Nineties within the Human-Computer Interaction, with the gradual replacement of User Experience as a major category of interaction design. Designing the interactive experience (emotional and aesthetic) becomes more important than Usability. But if the experience becomes the specific object of design, the materiality of the object, its shell, loses its importance. The evolution of design, through the spread of computing, leads to a pervasive dematerialization of everyday objects.

An Adaptive Regularized Proximal Newton-Type Methods for Composite Optimization over the Stiefel Manifold

Year: 2024
Subjects: subject: Optimization and Control (math.OC)

description: Recently, the proximal Newton-type method and its variants have been generalized to solve composite optimization problems over the Stiefel manifold whose objective function is the summation of a smooth function and a nonsmooth function. In this paper, we propose an adaptive quadratically regularized proximal quasi-Newton method, named ARPQN, to solve this class of problems. Under some mild assumptions, the global convergence, the local linear convergence rate and the iteration complexity of ARPQN are established. Numerical experiments and comparisons with other state-of-the-art methods indicate that ARPQN is very promising. We also propose an adaptive quadratically regularized proximal Newton method, named ARPN. It is shown the ARPN method has a local superlinear convergence rate under certain reasonable assumptions, which demonstrates attractive convergence properties of regularized proximal Newton methods.

description: We explore the properties of supernova (SN) "Refsdal" - the first discovered gravitationally lensed SN with multiple images. A large magnification provided by the galactic-scale lens, augmented by the cluster lens, gave us a unique opportunity to perform a detailed modelling of a distant SN at z=1.5. We present results of radiation hydrodynamics modelling of SN Refsdal. According to our calculations, the SN Refsdal progenitor is likely to be a more massive and energetic version of SN 1987A, i.e. a blue supergiant star with the following parameters: the progenitor radius $R_0 = (50 \pm 1) R_{\odot}$, the total mass $M_{tot}= (25\pm 2) M_{\odot}$, the radioactive $^{56}$Ni mass $M_{^{56}\mathrm{Ni}} = (0.26 \pm 0.05) \,M_{\odot}$, and the total energy release $E_{burst}=(4.7 \pm 0.8)\times10^{51}$ erg. Reconstruction of SN light curves allowed us to obtain time delays and magnifications for the images S2-S4 relative to S1 with higher accuracy than previous template-based estimates of Rodney \& et al. (2016). The measured time delays are $Δt_{S2-S1} = 9.5^{+2.6}_{-2.7} $ days, $Δt_{S3-S1} = 4.2^{+2.3}_{-2.3} $ days, and $Δt_{S4-S1} = 30^{+7.8}_{-8.2} $ days. The obtained magnification ratios are $μ_{S2/S1}= 1.14 \pm 0.02$, $μ_{S3/S1} = 1.01 \pm 0.02 $, and $μ_{S4/S1} = 0.35\pm 0.02$. We estimate the Hubble constant $H_0 = 68.6^{+13.6}_{-9.7}$ km s$^{-1}$ Mpc$^{-1}$ via re-scaling the time delays predicted by different lens models to match the values obtained in this work. With more photometric data on the fifth image SX, we will be able to further refine the time delay and magnification estimates for SX and obtain competitive constraints on $H_0$.

description: Irrigation vegetable farmers in Seymour District, Eastern Cape, have had problems concerning market access. Initial action by the researcher showed that problems can be solved. A survey showed younger farmers to be better educated, more businesslike and more eager to solve problems than older farmers. The unavailability of transport, poor infrastructure, lack of market information and to a lesser extent, dishonesty of some traders are major problems for these farmers. The community involved should be regarded as progressive, and can be expected to prosper once their problems have been solved.

description: Since the late Eighties, technological change and transition from analog to digital, led to a challenging of the classical categories of modernist design. With the development of Human Computer Interaction and its impact on theories of Functionalist Design, it has begun a process of interrogation – initially in a cognitive sense and then in the more properly aesthetic sense – which, through theories and practices increasingly dependent on computerization (Ubiquitous Computing), brings modernist theories about functionality to shift their interest on Usability and, then, from Usability to User Experience.

description: A reflection on the aesthetic status of some typical objects of everyday life, and the relationship we have with them, may originate from the development of “aesthetic experience” by John Dewey and Neopragmatism. The continuity between the common practices and aesthetic ones determines the significance of ordinary objects if they are linked to a project of enrichment and fulfillment of experience. A case that thematizes the richness of these practices in the contemporary world, and also the related theoretical and critical problems, is the production of skateboards. An established artist like Damien Hirst collaborates with the NYC-based streetwear brand Supreme; a new London-based brand, Palace Skateboards, and Tate realize together a few skateboard and a video.

description: This work presents a unified dissipaton-equation-of-motion (DEOM) theory and its evaluations on the Helmholtz free energy change due to the isotherm mixing of two isolated subsystems. One is a local impurity and another is a nonlocal Gaussian bath. DEOM constitutes a fundamental theory for such open quantum mixtures. To complete the theory, we construct also the imaginary-time DEOM formalism via an analytical continuation of dissipaton algebra, which would be limited to equilibrium thermodynamics. On the other hand, the real-time DEOM deals with both equilibrium structural and nonequilibrium dynamic properties. Its combination with the thermodynamic integral formalism would be a viable and accurate means to both equilibrium and transient thermodynamics. As illustrations, we report the numerical results on a spin--boson system, with elaborations on the underlying anharmonic features, the thermodynamic entropy versus the von Neumann entropy, and an indication of "solvent-cage" formation. Beside the required asymptotic equilibrium properties, the proposed transient thermodynamics also supports the basic spontaneity criterion.

description: In this article, we apply the Finsler spacetime to develop the Einstein field equations in the extension of modified geometry. Following Finsler geometry, which is focused on the tangent bundle with a scalar function, a scalar equation should be the field equation that defines this structure. This spacetime maintains the required causality properties on the generalized Lorentzian metric manifold. The matter field is coupled with the Finsler geometry to produce the complete action. In this work, we use modified gravity to develop the Einstein field equations from the variational principle. Developed Einstein field equations are employed on the strange stellar system to improve the study. The interior of the system is made of a strange quark, maintained by the MIT Bag equation of state. In addition, the modified Tolman-Oppenheimer-Volkov (TOV) equation is formulated. In particular, the anisotropic stress attains the maximum at the surface. The mass-central density variation justifies the stability of the system.

Biooxidation of a zinc sulphide ore

description: An experimental program was conducted on a zinc-sulphide ore containing 15% zinc in support of the development of the Teck Cominco HydroZinc™ process. The two primary types of experiments that were conducted were bacterially assisted short column experiments, and controlled potential, isothermal, chemical leaching experiments. This program was carried out in order to determine the kinetics of heap biooxidation of this zinc ore at controlled temperatures, and to determine the rates of heat generation under those conditions. In addition, the ores' topology, activation energy, and dependence on ferric and ferrous ions were determined. Once the primary objective of generating consistent, meaningful data was achieved, a concerted effort was made to fit the results with an existing mathematical model. This exercise was met with mixed results and it was concluded that the mathematical model, in its current stage of development, is insufficient to accurately describe the leaching of this ore. It was concluded from both the experimental data and the mathematical fits that the rate of bacterial leaching of this zinc ore is limited by transport of oxygen into solution. Results of the potentiostatic experiments indicate that the ore follows a variable order model, has an activation energy of 58.23 kJ mol ⁻¹, a reaction order of 2.30, and a dependency on ferric ions of O.342.

description: Recent geospatial machine learning studies have shown that the results of model evaluation via cross-validation (CV) are strongly affected by the dissimilarity between the sample data and the prediction locations. In this paper, we propose a method to quantify such a dissimilarity in the interval 0 to 100% and from the perspective of the data feature space. The proposed method is based on adversarial validation, which is an approach that can check whether sample data and prediction locations can be separated with a binary classifier. The proposed method is called dissimilarity quantification by adversarial validation (DAV). To study the effectiveness and general?ity of DAV, we tested it on a series of experiments based on both synthetic and real datasets and with gradually increasing dissimilarities. Results show that DAV effectively quantified dissimilarity across the entire range of values. Next to this, we studied how dissimilarity affects CV methods' evaluations by comparing the results of random CV method (RDM-CV) and of two geospatial CV methods, namely, block and spatial+ CV (BLK-CV and SP-CV). Our results showed the evaluations follow similar patterns in all datasets and predictions: when dissimilarity is low (usually lower than 30%), RDM-CV provides the most accurate evaluation results. As dissimilarity increases, geospatial CV methods, especially SP-CV, become more and more accurate and even outperform RDM-CV. When dissimilarity is high (>=90%), no CV method provides accurate evaluations. These results show the importance of considering feature space dissimilarity when working with geospatial machine learning predictions and can help researchers and practitioners to select more suitable CV methods for evaluating their predictions.

description: Some comments are required to put in perspective the results obtained by Ngwenya, Battese and Fleming (1997). In particular, it is necessary to examine their main conclusion that in 1988/89 there was a significant inverse relationship between the technical inefficiency of wheat farmers in the Eastern Free State and farm size, because this is in direct contrast with the findings of Van Zyl, Binswanger and Thirtle (1995) who used the same dataset.

description: We propose a method for quantum information processing using molecules coupled to an external laser field. This utilizes molecular interactions, control of the external field and an effective energy shift of the doubly-excited state of two coupled molecules. Such a level shift has been seen in the two-photon resonance experiments recently reported in Ref. [1]. Here we show that this can be explained in terms of the QED Lamb shift. We quantify the performance of the proposed quantum logic gates in the presence of dissipative mechanisms. The unitary transformations required for performing one- and two-qubit operations can be implemented with present day technology.

description: According to Hegel and to the romantic theory, Aesthetics is a philosophy of art. However, nowadays we can experience the beauty not only with art, but also with every product (fashion, videogames, cars, technological products). So we can query if the realm of aesthetics should hold also everyday products and how this could transform the traditional aesthetic categories.This essay aim to answer these questions. It aim furthermore to sketch the product’s theoretical foundations referring to national and international debate which have dealt with everyday aesthetics according to different point of view.

description: This paper presents a theoretical approach that explains farm household diversification decisions by the relative attractiveness of both food production and family businesses. The empirical analysis of diversified activities of Swiss farm households shows that a low household income leads to diversification by off-farm activities, while a high income leads to diversification by on-farm activities. It is also shown that arable farms, mountain farms and farm households with a non-agricultural education are more likely to enter off-farm activities.

description: The high Brazilian external dependence turns the persecution for foreign reserves a permanent concern. This paper analyzes soybean competitiveness after 1990 as it led Brazilian agricultural exports and became its main exchange value source. By using several indicators it concludes for an increasing competitiveness of the grain and decreasing for cake of soybeans since 1997. During the ninety decade there were expressive increases of crop productivity, but after that the production was due to area increases; from 1991 to 2003 doubled the share of inputs (fertilizers, corrective and pesticides) in the production cost, the expense with those imported inputs was multiplied by ten, while soybean and its derived product export value was multiplied by four; the reached competitiveness is considered not maintainable since the export value concentration exposes the country to risks related to international conjuncture.
