La politica del corpo maledetto: per una ricostruzione del significato civico della sepoltura tragica
Creators: name: Boschi, Alessandro

description: One of the most enlightening situations to recognize the link between the theatre and the πόλις is when the latter decides to accept or expel the remains of a tragic hero who lived his last days as a cursed or persecuted man. For instance, the Theban law which provides the burial of Eteocles’ body, but not of Polinices’ one, derives from the necessity to show that the city treats its friends and enemies differently. Similarly, in the Athenian historical reality of the months following the fall of the Four Hundred, a decree provided that the dead Phrynichus should be tried for treason, and that his bones should be dug up and removed from Attica. However, the tragic Athens appears to be hospitable to contaminated and dangerous beings, even admitting their burial within its own borders. This is the case of the Sophoclean Oedipus, who gives his body to Athens as a gift that brings strength and protection. The miserable body of a cityless man like Oedipus becomes the sacred bulwark of Athens, precisely when Theseus makes his guest a dweller in the city. In the same way, at the end of the Children of Heracles by Euripides, after having been an enemy, Eurystheus has become a saving metic, informing that, if his body is buried at Athena’s shrine, it will be a guarantee of protection of the πόλις. Bearing in mind the textual and contextual peculiarities of the various passages which will be analysed, the purpose of my contribution is to throw more light upon the political and civic significance of the tragic burial. Alessandro Boschi received a doctoral degree in Greek philology at the University of Pisa. His thesis, entitled Crizia tragico: testo critico, traduzione e commento delle testimonianze e dei frammenti, is a critical edition with a philological commentary of the testimonies and dramatic fragments attributed to Critias. During his doctorate, Alessandro Boschi conducted a six-month research visit at Bordeaux Montaigne University and the Ausonius Institute in Bordeaux. He has also participated in conferences in Pisa, Siena, Roma, Calgary, Warwick, Paris and Lyon. Alessandro Boschi is currently a postdoctoral researcher at the University of Pisa, where his research deals with the myth of the Atreidae in the fragments of Attic tragedy.

description: We analyze dynamics of the FRW models with global rotation in terms of dynamical system methods. We reduce dynamics of these models to the FRW models with some fictitious fluid which scales like radiation matter. This fluid mimics dynamically effects of global rotation. The significance of the global rotation of the Universe for the resolution of the acceleration and horizon problems in cosmology is investigated. It is found that dynamics of the Universe can be reduced to the two-dimensional Hamiltonian dynamical system. Then the construction of the Hamiltonian allows for full classification of evolution paths. On the phase portraits we find the domains of cosmic acceleration for the globally rotating universe as well as the trajectories for which the horizon problem is solved. We show that the FRW models with global rotation are structurally stable. This proves that the universe acceleration is due to the global rotation. It is also shown how global rotation gives a natural explanation of the empirical relation between angular momentum for clusters and superclusters of galaxies. The relation $J \sim M^2$ is obtained as a consequence of self similarity invariance of the dynamics of the FRW model with global rotation. In derivation of this relation we use the Lie group of symmetry analysis of differential equation.

KiDS+VIKING-450: Improved cosmological parameter constraints from redshift calibration with self-organising maps

description: We present updated cosmological constraints for the KiDS+VIKING-450 cosmic shear data set (KV450), estimated using redshift distributions and photometric samples defined using self-organising maps (SOMs). Our fiducial analysis finds marginal posterior constraints of $S_8\equivσ_8\sqrt{Ω_{\rm m}/0.3}=0.716^{+0.043}_{-0.038}$; smaller than, but otherwise consistent with, previous work using this data set ($|ΔS_8| = 0.023$). We analyse additional samples and redshift distributions constructed in three ways: excluding certain spectroscopic surveys during redshift calibration, excluding lower-confidence spectroscopic redshifts in redshift calibration, and considering only photometric sources which are jointly calibrated by at least three spectroscopic surveys. In all cases, the method utilised here proves robust: we find a maximal deviation from our fiducial analysis of $|ΔS_8| \leq 0.011$ for all samples defined and analysed using our SOM. To demonstrate the reduction in systematic biases found within our analysis, we highlight our results when performing redshift calibration without the DEEP2 spectroscopic data set. In this case we find marginal posterior constraints of $S_8=0.707_{-0.042}^{+0.046}$; a difference with respect to the fiducial that is both significantly smaller than, and in the opposite direction to, the equivalent shift from previous work. These results suggest that our improved cosmological parameter estimates are insensitive to pathological misrepresentation of photometric sources by the spectroscopy used for direct redshift calibration, and therefore that this systematic effect cannot be responsible for the observed difference between $S_8$ estimates made with KV450 and Planck CMB probes.

description: We study the spectroscopic properties of a sample of 10^3 void galaxies from the Sloan Digital Sky Survey (SDSS) and compare these with the properties of galaxies in higher density regions (wall galaxies). This sample of void galaxies covers the range of absolute magnitude from M_r=-13.5 to M_r=-22.5 in regions with density contrast delta < -0.6. In this paper we compare the equivalent widths of Halpha, [OII], [NII], Hbeta, and [OIII] of void and wall galaxies of similar luminosities and find that void galaxies have larger values, indicating that they are still forming stars at a high rate. A comparison of the Balmer break, as measured by the parameter Dn(4000), reveals that void galaxies have younger stellar populations than wall galaxies. Using standard techniques, we estimate Halpha and [OII] star formation rates of the void and wall galaxies and along with estimates of the stellar masses, we compute specific star formation rates. In most cases, we find that void galaxies have similar SFRs to wall galaxies but they are fainter and smaller mass. This means that, consistent with the EWs, void galaxies have higher specific star formation rates than wall galaxies.

title: Online citizen science projects: an exploration of motivation, contribution and participation
Creators: name: Curtis, Vickie
Publisher: name: The Open University
Year: 2015

description: The number of online citizen science projects has increased significantly over the past decade, yet some aspects of participation are poorly understood as is the motivation behind the involvement of the scientists who set up these projects, and the citizen scientists who take part. This thesis explores three different online citizen science projects (Foldit, Folding@home and Planet Hunters) using a case study approach and data collected through online surveys, interviews and participant observation. It explores the motivations that initiate and sustain participation, and it examines the various ways individuals can contribute to these projects. It also investigates how participants (both professional scientists and citizen scientists) interact online. A number of theoretical models of motivation and participation are considered. While many individuals register to take part in these projects, only a small proportion become active participants. These active citizen scientist volunteers are motivated to participate because they want to make a contribution to science or have a background interest in science. Scientists set up these projects in order to get help analysing large volumes of data, particularly those that require human pattern recognition or problem-solving skills. The complexity of the project task and the presence of certain technological features can affect how participants interact with each other, and how they contribute. Tasks that are complex are more likely to present opportunities for cooperation and collaboration, and may foster the development of online communities of practice. The findings of this research suggest that online citizen science projects have been important in making scientific research more open for a number of distributed volunteers. These individuals have responded to the challenges presented by these projects, increasing their scientific and technical understanding, and self-organising into various roles and teams in order to produce new knowledge.
Una vicenda tracia: Tereo fra tragedia e politica
Creators: name: Mancuso, Sabrina
Publisher: name: Frammenti sulla Scena (online)
Year: 2021

description: My paper focuses on the Thracian setting of Sophocles’ Tereus, which I regard as an innovation carried out by Sophocles himself. The originality of this choice can be demonstrated through an analysis of Thucydides’ (3, 29, 3) and Pausanias’ (10, 4, 8) witnesses, which attest a Daulian setting for the same story. It is therefore possible to demonstrate that the myth’s displacement resulting from its setting in Thrace can be read as a criticism of Thrace itself, with which Athens had difficult relations at the time. This argumentation is corroborated by an analysis of some aspects of Tereus: the differentiation between “foreigners” and “barbarians” presented in fragment 583 Radt2; the glossectomy which Tereus inflicted on Philomela (referring to the hostility of the barbarians toward ἰσηγορία); the prejudice about the greed of the barbarians (Fr. 587 Radt2); the possible Dionysian background (Frr, 591, 595a Radt2). In this respect, the witness of Thucydides (2, 29, 3), who defends the Thracian king Teres from the accusation of being related to Tereus, seems to be crucial, since in his opinion Tereus was a Thracian from Daulis. Thucydides’ polemical target could be Sophocles, who through his Tereus aimed to take position within the debate between philo-Thracian and anti-Thracian trends, particularly urgent in Athens during Teres’ and Sitalces’ hegemony over Thrace. Sabrina Mancuso is currently a Lecturer in Greek Grammar and Translation of Greek Texts at Eberhard-Karls-Universität Tübingen. After graduating in Pisa, she completed her Ph.D. jointly supervised in Tübingen and in Pisa in July 2020 with a dissertation focused on the mythical paradigm of Procne in Attic tragedy. Her main research interests are Attic tragedy (especially Sophocles), ancient epics, mythical examples, rhetoric, fragmentary poetry and digital critical editions.

description: The most salient feature of the spatial economy is the presence of a large variety of economic agglomerations. The purpose of this paper is to review some of the main explanations of this universal phenomenon, as they are proposed in urban economics and modern economic geography. Because of space constraints, we focus on the most recent contributions. Since models of comparative advantage have been extensively studied by international and urban economists, while models of spatial competition have attracted a lot of attention in industrial organization, we restrict ourselves to multiregional models of industrial agglomeration based on monopolistic competition. The paper is organized as follows. In the first part, we show why the competitive framework can hardly be the foundation for the economics of agglomeration. We then briefly review the alternative modeling strategies. In the hope to make our paper accessible to a broad audience, the second part presents in detail the two (specific) models that have been used so far to study the spatial distribution of economic activities. This leads us to put aside non-market institutions and mechanisms that stand at the source of various agglomeration externalities. Several extensions of these models are then discussed. This includes the comparison of market and optimum outcomes, the impact of forward-looking migrations and of urban costs, as well as the role of a heterogeneous labor force and of intermediate commodities. We conclude with some suggestions for further research together with some policy implications.

description: This contribution is an introduction to the main topics of spatial econometrics. We start analyzing the main problems raised by spatial data. The first one is heterogeneity : statisticians must take account of the fact that spatial units may not be directly comparable. They must correct for differences in size, form, structure and so on. The second one is interaction among units located in space, the intensity of which decreases with distance. These interactions lead to spatial autoregression and spatial autocorrelation. Then, the paper introduces to the main instruments used to represent and analyze spatial autocorrelation and autoregression : spatial graphs, weight matrices, contiguity matrices. It presents the main tests used to detect spatial autocorrelation, color tests on qualitative data, Moran and Geary tests for quantitative data. It shows how these tests can be interpreted. An illustrative example is also provided. Last, the paper shows how to deal with spatial autocorrelation and autoregression on the example of linear models. The main types of spatial linear models are presented : spatially autoregressive, spatially autocorrelated and their combination. Then, we explain why least squares methods are not well suited to estimate this type of models. Most often, econometric analysis will rest upon maximum likelihood methods. The paper shows how to use these methods in the specific context of spatial models, in order to find parameters estimates and to make tests on them.
Classical Goldstone modes in Long-Range Interacting Systems

description: For a classical system with long-range interactions, a soft mode exists whenever a stationary state spontaneously breaks a continuous symmetry of the Hamiltonian. Besides that, if the corresponding coordinate associated to the symmetry breaking is periodic, the same energy of the different stationary states and finite $N$ thermal fluctuations result in a superdiffusive motion of the center of mass for total zero momentum, that tends to a normal diffusion for very long-times. As examples of this, we provide a two-dimensional self-gravitating system, a free electron laser and the Hamiltonian Mean-Field (HMF) model. For the latter, a detailed theory for the motion of the center of mass is given. We also discuss how the coupling of the soft mode to the mean-field motion of individual particles may lead to strong chaotic behavior for a finite particle number, as illustrated by the HMF model.

The Ambiguities of Voluntary Self-Sacrifice: The Case of Macaria in Euripides’ 'Heracleidae'. A Dramaturgic Study
Creators: name: Bocholier, Julien
Publisher: name: Frammenti sulla Scena (online)
Year: 2021

description: Since the 1970s, the Euripidean motif of voluntary self-sacrifice is no longer envisaged as unambiguously eliciting the audience’s admiration, but as a potentially subversive force, which extols the bravery of one individual to expose the villainy of the community demanding bloodshed. This paper re-examines the validity and relevance of this ironic approach in the case of Euripides’ Heracleidae. First, it shows why the sudden withdrawal of Athens at the beginning of the second episode is not to be understood as denoting the corruption of the city and its king. Second, it deals with the peculiarity of the self-sacrifice scene, in which a nameless daughter of Heracles (traditionally called ‘Macaria’) willingly surrenders her life in order that Athens may obtain victory over Eurystheus: while she is purposely made on the pattern of Attic virginal heroines and objectively dies for the city, she claims to do so for her sole γένος. This apparent inconsistency has been resolved by scholars in terms of abstract political or gender analysis; this study envisages it in terms of dramaturgy and shows how Euripides exploits the still-dormant tension between γένος and πόλις in the rest of the play, down to the exodos, where it is made clear that the family of Heracles and the city of Athens will be in open conflict one day – i.e. in the present time of the spectators, for the play was probably staged in 430. In this drama, as in Erechtheus, patriotic feelings which seemed unproblematic and one-dimensional at first sight are submitted to a properly tragic reversal. Julien Bocholier is a former student of the École normale supérieure of Paris. A fourth-year doctoral candidate at Sorbonne Université and scholarship student at the Fondation Thiers (Institut de France), he is currently engaged into the edition, translation into French and commentary of Euripides’ Heracleidae under the supervision of Prof. Christine Mauduit (ENS Paris). Wekwords: Tragedy, Euripides, Macaria, self-sacrifice, polis, genos.

description: In this paper, we propose a fast extrinsic calibration method for fusing multiple inertial measurement units (MIMU) to improve visual-inertial odometry (VIO) localization accuracy. Currently, data fusion algorithms for MIMU highly depend on the number of inertial sensors. Based on the assumption that extrinsic parameters between inertial sensors are perfectly calibrated, the fusion algorithm provides better localization accuracy with more IMUs, while neglecting the effect of extrinsic calibration error. Our method builds two non-linear least-squares problems to estimate the MIMU relative position and orientation separately, independent of external sensors and inertial noises online estimation. Then we give the general form of the virtual IMU (VIMU) method and propose its propagation on manifold. We perform our method on datasets, our self-made sensor board, and board with different IMUs, validating the superiority of our method over competing methods concerning speed, accuracy, and robustness. In the simulation experiment, we show that only fusing two IMUs with our calibration method to predict motion can rival nine IMUs. Real-world experiments demonstrate better localization accuracy of the VIO integrated with our calibration method and VIMU propagation on manifold.
Il γάμος e gli elementi del paesaggio tragico nella parodo delle 'Supplici' di Eschilo
Creators: name: Re, Giulia
Publisher: name: Frammenti sulla Scena (online)
Year: 2021

description: The parodos of the Suppliant Women (1-175) shows references to natural elements and landscapes described in words by the characters, but not represented on scene. A closer observation of the ways these landscapes are mentioned allows to go back to hints of social and religious notions, and to practices related to marriage in V cent. B.C, as well as to recognize the imagery linked to divinities like Hera and Zeus Teleioi, whose action is alluded to, but not directly expressed in the text. The description of landscape gives the parodos a circular structure (sea-land-sea). My analysis will focus on the strategies of verbalizing landscape, trying to bring up divine actions through natural elements. Indeed, nature is where the Greeks recognized the presence of the gods and the setting of their manifestations. This is why landscapes turn to be a good field to investigate religious mentality of V cent. B.C. Athens. The aim of this paper is to show that the spectators of Attic drama were deeply influenced by their own socialized and religious experience of natural spaces and landscapes. Therefore, dramatic descriptions of space are modelled and conveyed to the audience according to shared competences and notions where ritual habits, divine powers and attributes, and every-day practices of landscapes are horizontally crossed together. By enhancing the religious components of the spaces where the Danaids are supposed to act, I will show how their uncompromising hostility towards sexuality and marriage is, from the very beginning of the play, destined to be normalized according to the divine τέλος prescribed by Hera -and Aphrodite- to all unmarried girls. Giulia Re è dottoranda di ricerca in Scienze dell’Antichità e Archeologia, curriculum antropologico, presso l’Università di Pisa, in cotutela con l’École Pratique des Hautes Études di Parigi. Il suo progetto di ricerca consiste in uno studio del paesaggio religioso nel corpus della tragedia attica di V sec. a.C. Lo scopo è analizzare le strategie di verbalizzazione del paesaggio in tragedia e le intersezioni tra la nozione di spazio e le forme del pensiero religioso e sociale di età classica, con particolare attenzione agli aspetti legati alla polivalenza delle manifestazioni divine che caratterizza il politeismo greco.

description: In an environment characterised by strong globalization trends and increasing uncertainty, firms are becoming more and more integrated within international networks. In the meantime, the new dynamics of the production system gives to localised learning an important role to play. This apparent duality leads to the question of firms’location and to the role of territory in their competitiveness. More specifically, the issue raised in this paper is the diversity of the sources of competitiveness of localised firms. The purpose is to determine the respective competitiveness effects of industrial spillovers (due to comparative advantages), spatial externalities (urban and industrial economies of agglomeration) and specific internal characteristics (due to firm organisation). These effects have been tested at the two stages of the export process : first the firms’decision to sell abroad or not and, secondly, the volume of exports of firms engaged in selling abroad. The originality of this study relates to the exploitation of the individual firms data, which allows the complexity of organisational forms (group, multiplant firm) to be linked to the diversity of spatial environments (urban areas, rural areas, etc.). Results confirm that territorial determinants play a significant role in firms’competitiveness. Among these factors, urban agglomeration economies are the most important. Thus firms located in an urban area have a greater propensity to export and export more than the others. But, taking into account the multiplant firms and their spatial organisation moderates this result. The location of their plants in several and different areas benefits their competitiveness. Finally, the fact of taking multiplant firms into account shows in particular that a firm, while benefiting from the advantages of urban district economies for its head office, can choose to locate some of its firms in rural areas in order to be more competitive. It can thus combine the generic externalities of urban agglomeration economies, required for the commercial activity of the firm, with the advantages for production of the proximity of raw materials. Industrial agglomeration plays also a significant and positive role but lesser than others. This would mean that urban economies (due to infrastructures, collective equipments or generic assets) or national specialisation have a more stimulating effect than local technological externalities.

description: We study the effect of non-relativistic, thermal matter in the jets of active galaxies (AGN) on the low-frequency non-thermal emission and the variability thereof. In matter-dominated jets, sizable quantities of gas should exist, in particular in the compression zones near the collision fronts that are an implicit ingredient of Fermi-type particle acceleration scenarios. Non-relativistic thermal gas in AGN jets noticably contributes to the optical depth at radio to infrared frequencies, and much less to the emission, with an efficiency that is strongly temperature-dependent. The observable flux of low-frequency emission is thus modulated by the temperature evolution of the thermal gas, and it can therefore display very complicated variability. For a particular particle energisation scenario we calculate the temperature evolution of the thermal plasma as well as the radiation transport of low-frequency emission, and thus derive simulated light curves at different frequencies and their typical correlation properties.

title: Eclipsing Binaries and Period Changes in the SuperWASP Archive
Creators: name: Lohr, Marcus
Publisher: name: The Open University
Year: 2015

description: The aim of this research project has been to investigate eclipsing binaries using archival data from the SuperWASP (Wide Angle Search for Planets) survey, and specifically to search for evidence of orbital period variations. The short cadence and long time base of SuperWASP light curves make them highly suitable for variable star research of many kinds, and the size of the database (~30 million objects) allows for the discovery and study of rare objects and stellar types. Techniques optimized for analyzing SuperWASP data were developed over the course of the research, using custom IDL codes, and proved successful in measuring orbital periods and detecting period changes in real and synthetic test data. Employing these, original results were achieved in a range of areas. A sample of 143 eclipsing binary candidates were found with periods close to the short-period limit of the period distribution for main sequence binaries, which shed light on the likely cause of the limit. Significant period increases and decreases were detected in many of these, and several individual objects were followed up with spectroscopic and multicolour photometric observations, by ourselves and others, to allow confirmation of their binary nature and modelling to determine system and component parameters. Amongst these were a probable close triple system containing a low-mass contact binary, and a doubly-eclipsing quintuple system, only the sixth known of its kind. Eleven post-common-envelope eclipsing binaries were also studied for evidence of period changes, potentially associated with circumbinary planets; our findings add to the ongoing debate on the reality and stability of planetary systems in such environments. Finally, we used our findings on period changes in ~14000 candidate SuperWASP eclipsing binaries of all types to estimate the higher-order multiplicity fraction of such systems.

description: In this paper, we analyse the inventory and ordering policies of two firms, when (i) each firm has its own supplier and market but, (ii), the first firm may act as a second supplier of the second one. This allows us to study the interest of improving horizontal coordination between producers in order to minimize shortages or overstocking phenomena due to demand hazards : such producer-to-producer relationships are indeed more and more developed in numerous agro-food chains (like fruit chains). We develop a general newsvendor-like formulation of the optimal procurement and inventory policies, and calculate chain profits according to various levels of coordination between the two firms. An application to the case of a uniform demand is analysed more precisely. We then use a numerical analysis to define the conditions under which a high level of coordination may be interesting for both firms and the whole chain.

description: We study the quantum phase transition upon variation of the fermionic density $ν$ in a solvable model with random Yukawa interactions between $N$ bosons and $M$ fermions, dubbed the Yukawa-SYK model. We show that there are two distinct phases in the model: an incompressible state with gapped excitations and an exotic quantum-critical, non-Fermi liquid state with exponents varying with $ν$. We show analytically and numerically that the quantum phase transition between these two states is first-order, as for some range of $ν$ the NFL state has a negative compressibility. In the limit $N/M\to \infty$ the first-order transition gets weaker and asymptotically becomes second-order, with an exotic quantum-critical behavior. We show that fermions and bosons display highly unconventional spectral behavior in the transition region.

La saga degli Atridi tra Eschilo e Littell
Creators: name: Beta, Simone
Publisher: name: Frammenti sulla Scena (online)
Year: 2021

description: One of the last examples of the long success of the plot of Aeschylus’ Oresteia in modern literature is the controversial novel The kindly ones, written (in French) by the American-born author Jonathan Littel in 2006 and translated into English in 2009. The chapter deals with the quite hidden (but consistent) connections between the mythical story as told by the Greek playwright in the fifth century BCE and the dramatic events that mark the personal and public life of the protagonist of the 1000-pages book, the SS-officer Maximiliem Aue, who eventually succeeds in escaping the pursuit of the Erinyes, the goddesses of revenge. At the end of the novel, in the town of Berlin invaded by the Russian soldiers, the Erinyes become, as in the outcome of the Greek tragedy, Eumenides – this is in fact the meaning of the title, in all the main translations (Les Bienveillantes, Le benevole, Die Wohlgesinnten, Las Benévolas, As Benevolentes, etc.). Simone Beta is Full Professor of Greek language and literature at the University of Siena. His research centers on Greek and Roman drama, wine and symposium, epigrams and riddles, and the reception of classical antiquity. He has written Il linguaggio nelle commedie di Aristofane: parola positiva e parola negativa nella commedia antica (Rome 2004), Il labirinto della parola: enigmi oracoli e sogni nella cultura antica (Turin 2016) and Io, un manoscritto: l’Antologia Palatina si racconta (Roma 2017). With L. Della Bianca he has written Il dono di Dioniso. Il vino nella letteratura e nel mito in Grecia e a Roma (Rome 2015); with F. Puccio, Il dono di Afrodite. L’eros nella letteratura e nel mito in Grecia e a Roma (2019). He has published an anthology of Greek sympotic epigrams (Vino e poesia. Centocinquanta epigrammi greci sul vino, Milan 2006) and translated Sophocles’ Antigone (Milan 2020) and Aristophanes’ Lysistrata (Milano 2020). Keywords: Aeschylus, Orestes, Erinyes, World War II, Nazism

description: To understand spin interactions in materials of the Cu$_2$Sb structure type, inelastic neutron scattering of Fe$_2$As single crystals was examined at different temperatures and incident neutron energies. The experimental phonon spectra match well with the simulated phonon spectra obtained from density functional theory (DFT) calculations. The measured magnon spectra were compared to the simulated magnon spectra obtained via linear spin wave theory with the exchange coupling constants calculated using the spin polarized, relativistic Korringa-Kohn-Rostoker method in Zhang et al. (2013). The simulated magnon spectra broadly agree with the experimental data although, the energy values are underestimated along the $K$ direction. Exchange coupling constants between Fe atoms were refined by fits to the experimental magnon spectra, revealing stronger nearest neighbor Fe1-Fe1 exchange coupling than previously reported. The strength of this exchange coupling is almost an order of magnitude higher than other exchange interactions despite the three-dimensional nature of the phonon interactions. The lack of scattering intensity at energies above 60 meV makes unconstrained determination of the full set of exchange interactions difficult, which may be a fundamental challenge in metallic antiferromagnets.

Discreteness-induced Stochastic Steady State in Reaction Diffusion Systems: Self-consistent Analysis and Stochastic Simulations

description: A self-consistent equation to derive a discreteness-induced stochastic steady state is presented for reaction-diffusion systems. For this formalism, we use the so-called Kuramoto length, a typical distance over which a molecule diffuses in its lifetime, as was originally introduced to determine if local fluctuations influence globally the whole system. We show that this Kuramoto length is also relevant to determine whether the discreteness of molecules is significant or not. If the number of molecules of a certain species within the Kuramoto length is small and discrete, localization of some other chemicals is brought about, which can accelerate certain reactions. When this acceleration influences the concentration of the original molecule species, it is shown that a novel, stochastic steady state is induced that does not appear in the continuum limit. A theory to obtain and characterize this state is introduced, based on the self-consistent equation for chemical concentrations. This stochastic steady state is confirmed by numerical simulations on a certain reaction model, which agrees well with the theoretical estimation. Formation and coexistence of domains with different stochastic states are also reported, which is maintained by the discreteness. Relevance of our result to intracellular reactions is briefly discussed.

4 scenarios for online teaching and professional development: concrete examples and practical advice
Creators: name: Parmentier, Jean-François
name: Vicens, Quentin
Publisher: name: Zenodo
Year: 2021

description: This booklet was specifically written to address issues arising upon the COVID-19 pandemic. The text was originally written in French, before being translated into English by the authors. It contains excerpts from the book entitled Enseigner dans le supérieur Méthodologie et Pédagogies Actives (Parmentier & Vicens, Dunod, 2019), upon agreement with the publisher. Almost overnight in Spring 2020, we all found ourselves under a stay-at-home order. We were asked to switch from on-site to remote teaching. We took the dive... Easier said than done! Luckily, whether online or in class, the fundamental role of the teacher/instructor remains the same: s/he designs, initiates and facilitates activities that ensure cognitive engagement to promote learning. But because a virtual environment is unique and often intimidating, a careful organization is necessary to establish a climate that fosters learning. As certain goals are best achieved using certain tools, learning objectives motivate the choice of a particular technology. This type of e-learning offers an opportunity to rethink one's own teaching, as learning happens both during and in-between sessions.
 Instead of asking ourselves "What should I do during my next video conference?", we ask: "When, how, and what should I teach to my students?". Teaching is rather continuous, through a series of synchronous and asynchronous activities, which are linked to one other and to the learning objectives. The four scenarios presented in this book are based on principles and methods derived from experimental research in teaching and cognitive psychology. We chose their layout through our accumulated experience with online learning. Our aim is to provide the reader with suggestionsthat are reliable, because they are based on educational research, but also in line with the reality of the job as a teacher/trainer.
