Inner shell and valence shell electron excitation of gaseous molecules studied by electron energy loss spectroscopy
Creators: name: Sodhi, Rana N. S.
Publisher: name: University of British Columbia
Year: 2010

description: Electron energy loss spectroscopy has been used to obtain the inner shell electron excitation spectra of several different series of gaseous molecules. The spectra were all recorded under small momentum transfer conditions (usually 2.5 keV impact energy and small angle (~1°) scattering) and all spectral regions (both central atom and ligand) accessible by the present instrumentation (<1000 eV) have been measured. The series of molecules investigated include nitrogen containing molecules (NF₃, NH₃ and the methyl amines) and several phosphorus compounds (PX₃, X = H, F, Cl and CH₃; PF₅, OPF₃ and OPCL₃). In addition the spectra of Si(CH₃)₄ have been obtained and compared with published spectra of related Si containing compounds. All of the inner shell spectra show continuum structures which in many cases can be reasonably assigned to σ* shape-resonances. However, comparison of the inner shell electron excitation spectra of NF₃ with the X-ray photoelectron spectra (also reported here) show that continuum structure can also be ascribed, in some cases, to onsets of "shake-up" continua. The relationship of shape-resonance position and bond length is also examined in the systems studied here. The valence shell electron energy loss spectra of many of the above molecules are also reported. The assignment of these spectra is shown to be greatly facilitated by a comparison with the inner shell spectra. Finally, the inner shell and valence shell electron energy loss spectra of trans-1,3-butadiene and allene are also reported and assigned. In particular, the spectral assignment of the inner shell spectrum of allene allows clarification of its complex and controversial valence shell spectrum.
Immediacy and Its Hidden Infrastructure: When Amazon Extends Its Delivery Times During the Covid-19 Pandemic
Creators: name: Salles, Claire
Publisher: name: img journal
Year: 2021

description: During the confinement due to the Covid-19 pandemic, Amazon faced crushing demands. The firm chose to extend delivery times for non-essential in-stock goods and to hire more workers. These strategies contrast with Amazon’s usual core of business: making delivery always faster and replace as soon as possible most workers by robots. By describing this transient episode of voluntarily extended delivery times by Amazon and by inscribing it in the history of immediacy as a paradoxical horizon of mediations, as discussed in the field of media theory, the article shows that Amazon’s strategies of adaptation during the Covid-19 pandemic reveal once again what media studies had already emphasized: that many technological, logistic and human mediations are required to fulfill an online order as soon as possible, tangentially immediately. The article finally highlights an understated aspect of mediations: the importance of economic factors in shaping our societies, where shrinking spatial distances by getting separate things closer ever faster is economically profitable in spite of hidden and disastrous consequences on work conditions, on the global organization of the retailing and circulation of goods, and on the environment.

description: Developing an expression of resonant x-ray scattering (RXS) amplitude which is convenient for investigating the contributions from the higher rank tensor on the basis of a localized electron picture, we analyze the RXS spectra from the magnetic phases of Ho near the $M_{4,5}$ absorption edges. At the $M_5$ edge in the uniform helical phase, the calculated spectra of the absorption coefficient, the RXS intensities at the first and second satellite spots capture the properties the experimental data possess, such as the spectral shapes and the peak positions. This demonstrates the plausibility of the adoption of the localized picture in this material and the effectiveness of the spectral shape analysis. The latter point is markedly valuable since the azimuthal angle dependence, which is one of the most useful informations RXS can provides, is lacking in the experimental conditions. Then, by focusing on the temperature dependence of the spectral shape at the second satellite spot, we expect that the spectrum is the contribution of the pure rank two profile in the uniform helical and the conical phases while that is dominated by the rank one profile in the intermediate temperature phase, so-called spin slip phase. The change of the spectral shape as a function of temperature indicates a direct evidence of the change of magnetic structures undergoing. Furthermore, we predict that the intensity, which is the same order observed at the second satellite spot, is expected at the fourth satellite spot from the conical phase in the electric dipolar transition.

description: This qualitative doctoral dissertation investigates the influence of the characteristics and conditions of complex learning systems on the emergence, sustainability, and diffusion of learning of four professional learning communities (PLCs). These PLCs were associated with a large-scale initiative focused on enhancing mathematics teaching and learning in Grade 9 in Ontario, Canada. This study took place in 2021, five years after completion of the professional learning initiative in 2016 and focused on deepening understanding of how learning emerged during the initiative and how learning was sustained and diffused after the original initiative. The study employed a complexity science informed multiple-case study approach, utilizing a variety of data collection methods including secondary analysis of original project data, surveys, and interviews. Data analysis followed an iterative process, using complexity science as a framework, to analyze data and identify key themes. Findings revealed that all the characteristics and conditions of complex learning systems manifested across the cases and the whole initiative. Key conditions and characteristics such as decentralized control, self-organization, and nestedness supported neighbour interactions which contributed to teacher learning. The Diffusion of Innovation model was utilized to better describe how and why these themes supported teacher learning. These findings contribute to the understanding of how to support teacher learning in educational contexts and provide insights for educators and researchers seeking to promote effective professional learning initiatives. In conclusion, this study highlights the need to consider educational settings as interconnected nested systems that interact to influence learning across different systems. Professional learning initiatives within these systems need to incorporate teacher agency over an extended time period to allow for the development of professional relationships and communities of learners. These communities were observed to self-organize in ways that best supported and sustained their own learning and allowed the learning to diffuse to others in learning systems. These findings underscore the importance of creating supportive environments that fosters collaboration, connections, teacher agency, and shared purpose, thereby enhancing professional learning and educational outcomes.

description: The hot nuclear matter created at the Relativistic Heavy Ion Collider (RHIC) has been characterized by near-perfect fluid behavior. We demonstrate that this stands in contradiction to the identification of QCD quasi-particles with the thermodynamic degrees of freedom in the early (fluid) stage of heavy ion collisions. The empirical observation of constituent quark ``$n_q$'' scaling of elliptic flow is juxtaposed with the lack of such scaling behavior in hydrodynamic fluid calculations followed by Cooper-Frye freeze-out to hadrons. A ``quasi-particle transport'' time stage after viscous effects break down the hydrodynamic fluid stage, but prior to hadronization, is proposed to reconcile these apparent contradictions. However, without a detailed understanding of the transitions between these stages, the ``$n_q$'' scaling is not a necessary consequence of this prescription. Also, if the duration of this stage is too short, it may not support well defined quasi-particles. By comparing and contrasting the coalescence of quarks into hadrons with the similar process of producing light nuclei from nucleons, it is shown that the observation of ``$n_{q}$'' scaling in the final state does not necessarily imply that the constituent degrees of freedom were the relevant ones in the initial state.

description: Pairing symmetry which characterizes the superconducting pairing mechanism is normally determined by measuring the superconducting gap structure ($|Δ_k|$). Here, we report the measurement of a strain-induced gap modulation ($\partial|Δ_k|$) in uniaxially strained Ba$_{0.6}$K$_{0.4}$Fe$_2$As$_2$ utilizing angle-resolved photoemission spectroscopy and $in$-$situ$ strain-tuning. We found that the uniaxial strain drives Ba$_{0.6}$K$_{0.4}$Fe$_2$As$_2$ into a nematic superconducting state which breaks the four-fold rotational symmetry of the superconducting pairing. The superconducting gap increases on the $d_{yz}$ electron and hole pockets while it decreases on the $d_{xz}$ counterparts. Such orbital selectivity indicates that orbital-selective pairing exists intrinsically in non-nematic iron-based superconductors. The $d_{xz}$ and $d_{yz}$ pairing channels are balanced originally in the pristine superconducting state, but become imbalanced under uniaxial strain. Our results highlight the important role of intra-orbital scattering in mediating the superconducting pairing in iron-based superconductors. It also highlights the measurement of $\partial|Δ_k|$ as an effective way to characterize the superconducting pairing from a perturbation perspective.

Defying Distance

description: In 2018 as part of my long-term project the Archive of Gestures, I created a participatory dance performance with three Palestinian artist refugees entitled Gesturing Refugees. The performance faced many obstacles during the creation period related to UK visa denial to the artists, which resulted in the creation process taking place digitally, as an attempt to defy the physical distance among the artists and later also between the artists and the audience. To insist on this formal and political choice, in 2020 I developed Past-inuous, an interactive dance video, created over a digital platform with eleven Palestinian dancers, most third generation refugees, some living in the diaspora and others in Palestine. Through the work, I investigated ways of defying distance between third generation Palestinian refugees, which was created by Israel’s regime of dispossession. I did that by experimenting with how a digital platform can be remediated into a creative space for rehearsal, creation and transmission of bodily archives, through an interactive dance video with the viewers. But also by reflecting on the technical issues and delays caused by specific political conditions of disadvantage which arise during such a process, and exploring ways of using these issues in the video itself, so as to reflect the creation process and involve the viewers, especially now that during the pandemic, working at distance through online platforms has become a collective global experience.

Notes on the Proxemics of the ‘Non Place-Time’
Creators: name: Puma, Paola
Publisher: name: img journal
Year: 2021

description: During the period of confinement due to the pandemic emergency, the overly abused definition of ‘non place’ introduced in 1992 by Marc Augé seems to have found an involuntary and unexpected actualization, composing itself with the specular notion here defined as ‘non time’. The space-time expansion due to the sudden absence of bodies in the urban space and to the forced alternation of the monochronic and the polychronic time is at the basis of the atypical urban experience lived in the weeks of domestic isolation, which has made evident even to the wider public how much the city is a complex multidimensional agglomeration where many intangible elements coexist with the material dimension of the city. The notion of ‘non place-time’ is investigated through the analysis of the link between man, time and place and the reversal determined by the various space-time caesuras that occurred between people and between people and the collective scene of the city, as well as the definition of technological ‘immediate’ as an emerging co-constitutive process of personal experience and the environment.

description: Market-based conservation instruments, such as payments, auctions or tradable permits, are environmental policies that create financial incentives for landowners to engage in voluntary conservation on their land. But what if ecological processes operate across property boundaries and land use decisions on one property influence ecosystem functions on neighboring sites? This paper examines how to account for such spatial externalities when designing market-based conservation instruments. We use an agent-based model to analyze different spatial metrics and their implications on land use decisions in a dynamic cost environment. The model contains a number of alternative submodels which differ in incentive design and social interactions of agents, the latter including coordinating as well as cooperating behavior of agents. We find that incentive design and social interactions have a strong influence on the spatial allocation and the costs of the conservation market.

Human Screens: Bodies, Media and the Meaning of Violence
Creators: name: Perugini, Nicola
Publisher: name: img journal
Year: 2021

description: From phalanx-fighting, through the use of multiple distance weapons, to the development of airpower and drone warfare in the last century, the history of armed conflicts is one of increasing distance from which people are killed, but also one of increasing weaponization of the human body. Starting from World War I, innocent civilians who were used as human shields to protect military targets in violation of the laws of war were often defined as ‘human screens’. The notion of human screen, I argue in this article, is not merely a synonym for human shield. In fact, the human screen is not only a human weapon. As I show in this archaeological exploration, the process of transformation of the human body into a screen translates also into the development of a new media technology that both allows to modulate the use of lethal force and shape the perception and political meaning of violence in the battlefield.

Networked Screens: Topologies of Distance and Media Regime of Immunization
Creators: name: Moskatova, Olga
Publisher: name: img journal
Year: 2021

description: Media theory usually foregrounds transmission, storage, and processing as elementary media operations, neglecting the role media play in protecting living beings. However, the biopolitical and discursive reactions to the spread of Covid-19 have evidenced how protection and establishing safe distances can be implicated in the media process of transmission, which viral infection is, basically. Takingthe window photos reacting to the pandemic-induced isolation in early 2020 as a starting point, I propose to examine the dynamics of distance and proximity by focusing on the protective functionalities of small networked screens. Today, networked screens such as laptops, tablets, smartphones, or television dominate our everyday and personal media use. Their omnipresence and our permanent attachment to them became even stronger during the Corona crisis, giving the screens new political significance. Placed between the self and the world, screens are able to cocreate protective topologies of distance and, thus, to fulfill immunitary functions in addition to their communicative and connective ones. In order to elaborate on this double operativity, I will draw on etymological, media archaeological, and media theoretical understandings of screens as protective ‘shields’, ‘barriers’, and ‘filters’ and combine them with the philosophical perspectives on immunization developed by Roberto Esposito and Peter Sloterdijk.

description: In recent years, advances in computational power and spatial data analysis (GIS, remote sensing, etc) have led to an increase in attempts to model the spread and behaviour of wildland fires across the landscape. This series of review papers endeavours to critically and comprehensively review all types of surface fire spread models developed since 1990. This paper reviews models of a physical or quasi-physical nature. These models are based on the fundamental chemistry and/or physics of combustion and fire spread. Other papers in the series review models of an empirical or quasi-empirical nature, and mathematical analogues and simulation models. Many models are extensions or refinements of models developed before 1990. Where this is the case, these models are also discussed but much less comprehensively.

Apology for Technical Distance: But Beware the Feedback!
Creators: name: Montani, Pietro
Publisher: name: img journal
Year: 2021

description: Philosophy boasts an ancient familiarity with the practice of taking distance, which it tendentially conceives as a human condition (in transcendental or anthropological sense): the human being is par excellence an ek-static being. Arguably, this issue is rooted in the fundamental mode of being of the human body (but not only human), and has also a structural and not adventitious relationship to technology. A classic neuroscientific experiment shows that technical distancing can produce unpredictable neuro-plastic effects, as well as a general reorganization of behavior based on the emergence of a meta-operative agency. The agency thus enhanced, however, may in turn give rise to a genuine dialectical opposition between plastic expansion and self-referential contraction of behavior. Some examples will help shed light on this dialectic and eventually highlights some requirements that are necessary, though not sufficient, to adequately cope with the social distancing imposed by the anti-Covid measures managed by digital technologies, transforming the emergency into opportunities for the future.

description: We derive generalization of the Balitsky-Kovchegov (BK) equation for a dipole, which consists of a parton and an antiparton of arbitrary charge. At first, we develop one method of indexless transformation of color expressions. The method is based on an evaluation of the Casimir operator on a tensor product. From the JIMWLK equation we derive the evolution equation for a single parton and prove gluon Reggeization in an arbitrary color channel. We show that there is a color duplication of such Regge poles. Higher t-channel color exchange has its own Regge pole, which residue is proportional to the quadratic Casimir. Taking a fundamental representation, we derive the usual BK equation and shed new light on the meaning of linear and nonlinear terms. Finally, we discuss a linearized version of the generalized BK equation.

description: A set of normative standards, known as ‘sustainable finance’, have diffused globally to enhance environmental sustainability. This thesis examines how global sustainable finance norms have been locally adopted in Indonesia by focusing on how relevant non-state actors – bank employees and environmental activists – interpreted and responded to sustainable finance. Through in-depth analysis of interview and written data, this thesis revealed the epistemic frameworks held by different non-state actors that guided their interpretations and responses to sustainable finance. Although the findings suggest Indonesian banks have strengthened the environmental policies and practices, the change is constrained by the deeply-held belief in profit generation.

description: From Sherlock Jr. (1924) by Buster Keaton, to Laura by Shuji Terayama (1974), or Videodrome by David Cronenberg (1983), to more recent to Leto by Kirill Serebrennikov (2018), experimental and mainstream cinema has explored crossings through the screen to attempt erasing borders between the viewers and those represented. Let’s Reset the Clock (from French On va remettre les pendules à l’heure), is a two-and-a-half minute colour video that I chose to inscribed in this tradition. In this artwork, split screen visual process is used to remove distances, in order to put two characters –I, the author, and my own grandmother– face to face. As the latter has passed away, Let’s Reset the Clock, constitutes an attempt to remediate distances created by the mourning and a reflection about the way images can bridge those separated by space and by the time.

description: The influence of quantized electromagnetic fields on a nonrelativistic charged particle moving near a conducting plate is studied. We give a field-theoretic derivation of the nonlinear, non-Markovian Langevin equation of the particle by the method of Feynman-Vernon influence functional. This stochastic approach incorporates not only the stochastic noise manifested from electromagnetic vacuum fluctuations, but also dissipation backreaction on a charge in the form of the retarded Lorentz forces. Since the imposition of the boundary is expected to anisotropically modify the effects of the fields on the evolution of the particle, we consider the motion of a charge undergoing small-amplitude oscillations in the direction either parallel or normal to the plane boundary. Under the dipole approximation for nonrelativistic motion, velocity fluctuations of the charge are found to grow linearly with time in the early stage of the evolution at the rather different rate, revealing strong anisotropic behavior. They are then asymptotically saturated as a result of the fluctuation-dissipation relation, and the same saturated value is found for the motion in both directions. The observational consequences are discussed. plane boundary. Velocity fluctuations of the charge are found to grow linearly with time in the early stage of the evolution at the rate given by the relaxation constant, which turns out to be smaller in the parallel case than in the perpendicular one in a similar configuration. Then, they are asymptotically saturated as a result of the fluctuation-dissipation relation. For the electron, the same saturated value is obtained for motion in both directions, and is mainly determined by its oscillatory motion. Possible observational consequences are discussed.

description: In this paper we study the diameter of the random graph $G(n,p)$, i.e., the the largest finite distance between two vertices, for a wide range of functions $p=p(n)$. For $p=\la/n$ with $\la>1$ constant, we give a simple proof of an essentially best possible result, with an $O_p(1)$ additive correction term. Using similar techniques, we establish 2-point concentration in the case that $np\to\infty$. For $p=(1+ε)/n$ with $ε\to 0$, we obtain a corresponding result that applies all the way down to the scaling window of the phase transition, with an $O_p(1/ε)$ additive correction term whose (appropriately scaled) limiting distribution we describe. Combined with earlier results, our new results complete the determination of the diameter of the random graph $G(n,p)$ to an accuracy of the order of its standard deviation (or better), for all functions $p=p(n)$. Throughout we use branching process methods, rather than the more common approach of separate analysis of the 2-core and the trees attached to it.

description: Investigating the pressure dependence of the superconducting (SC) transition temperature $T_{\rm c}$ is crucial for understanding the SC mechanism. Herein, we report on the pressure dependence of $T_{\rm c}$ in the nonmagnetic topological line-nodal material CaSb$_2$, based on measurements of electric resistance and alternating current magnetic susceptibility. $T_{\rm c}$ initially increases with increasing pressure and peaks at $\sim$ 3.1~GPa. With a further increase in pressure, $T_{\rm c}$ decreases and finally becomes undetectable at 5.9~GPa. Because no signs of phase transition or Lifshitz transition are observed in the normal state, the peculiar peak structure of $T_{\rm c}$ suggests that CaSb$_2$ has an unconventional SC character.

description: The discovery that a substantial fraction of Kuiper Belt objects (KBOs) exists in binaries with wide separations and roughly equal masses, has motivated a variety of new theories explaining their formation. Goldreich et al. (2002) proposed two formation scenarios: In the first, a transient binary is formed, which becomes bound with the aid of dynamical friction from the sea of small bodies (L^2s mechanism); in the second, a binary is formed by three body gravitational deflection (L^3 mechanism). Here, we accurately calculate the L^2s and L^3 formation rates for sub-Hill velocities. While the L^2s formation rate is close to previous order of magnitude estimates, the L^3 formation rate is about a factor of 4 smaller. For sub-Hill KBO velocities (v << v_H) the ratio of the L^3 to the L^2s formation rate is 0.05 (v/v_H) independent of the small bodies' velocity dispersion, their surface density or their mutual collisions. For Super-Hill velocities (v >> v_H) the L^3 mechanism dominates over the L^2s mechanism. Binary formation via the L^3 mechanism competes with binary destruction by passing bodies. Given sufficient time, a statistical equilibrium abundance of binaries forms. We show that the frequency of long-lived transient binaries drops exponentially with the system's lifetime and that such transient binaries are not important for binary formation via the L^3 mechanism, contrary to Lee et al. (2007). For the L^2s mechanism we find that the typical time, transient binaries must last, to form Kuiper Belt binaries (KBBs) for a given strength of dynamical friction, D, increases only logarithmically with D. Longevity of transient binaries only becomes important for very weak dynamical friction (i.e. D \lesssim 0.002) and is most likely not crucial for KBB formation.

Remediating the Distance from the Divine: An Archaeological Essay Doctored Photographs-Exhibition Devices-Cinematographic Effect
Creators: name: Gizzi, Ferdinando
Publisher: name: img journal
Year: 2021

description: Catholicism has always maintained a deep, even ontological, relationship with images and their mediations on account and by virtue of its particular interpretation of the dogma of the Incarnation. And yet, in the second half of nineteenth century –especially ‘after Lourdes’, that is, after the mediatic and popular fortune of the supernatural apparitions to Bernadette Soubirous– the Christian ‘scopic’ drive spread and grew stronger in France, being redefined in new ‘spectacular’ modalities and forms. These aimed to bring the divine closer to the spectator’s physical and subjective experience, in accordance with the broadest process of subjectivation undergone at this time by the experience of seeing –the ‘gaze’– in its whole. My paper will focus, from an archaeological perspective, on three case studies within this remediation turning point: the attempts to photograph a Marian apparition in the small, peripheral village of Tilly-sur-Seulles between 1896 and 1897; the trompe-l’oeil devices employed by the artist Munkácsy and the galleristart dealer Sedelmeyer for the exhibition of lifesized Christological paintings during the 1880s and 1890s that engendered empathic ‘spectatorial’ reactions; and the emergence of the cinematographic apparatus –and of its phenomenological “train effect”– in conjunction with religious imaginaries, persons, uses and places.

Reunited? On the Aesthetics and Rhetoric of Meeting the Dead Through Virtual Reality
Creators: name: Conte, Pietro
Publisher: name: img journal
Year: 2021

description: Even though death creates irremediable distance between the living and the departed, human beings have been struggling since ages to bring the absent once again present through any form of available media. In all of the multifarious attempts at making the dead seem as if alive, a distance of the living from the departed was nevertheless retained in that the deceased was not really present, but only ‘presentified’ through a clearly perceivable medium. Yet nowadays, virtual reality promises to finally bridge the gap and make the living cross the border of the afterworld. By focusing on the paradigmatic case study of a South Korean mother who in February 2020 ‘met’ her dead daughter through a VR simulation, this essay takes into account both the visual and the linguistic strategies used to convey the idea of a direct, non-mediated ‘encounter’ or ‘reunion’ between the two. The overall objective of the article is to show that in immersive virtual environments, despite all rhetoric, the dialectic between proximity and distance which is common to the traditional notions of both the dead and the image is not only still present, but also greater than ever before.

Hermann Maertens’ Der Optischemaassstab and the Photography of Architecture
Creators: name: Colonnese, Fabio

Publisher: name: img journal
Year: 2021

description: The work of the German architect Hermann Eduard Maertens (1823-1898), and in particular his research on the Optische-Maassstab, results in a scientific, geometric tool, which was largely considered by urban planners and designers in the 20th century, to link the physiology of vision to the visual harmony of architecture. Based on the concept that distancing is an implicit, unaware consequence of beholder’s specific visual intents, the Optical Scale proposes a triad of angles, to be measured on the vertical plane, through which analyzing or designing become a function of sight. The authors conjecture that some of the arbitrary features of his tool may be attributed to a specific interest in early results of photography of architecture as, although Maertens apparently ignored it, both his approach and photographs share a direct derivation from the tradition of architectural representation.

title: Independent morphological and genetic diversification in close geographic and phylogenetic proximity: Typoderus weevils (Coleoptera) in the Uluguru Mountains, Tanzania
Creators: name: Grebennikov, Vasily V.

description: The Eastern Arc Mountains (EAM) of Tanzania form an island-type archipelago of wet and cool rainforests widely separated by extremely hot and dry savannah. This paper reports novel phylogeographical analyses of the low-dispersing and forest-dependent Typoderus weevils in the Uluguru block of the EAM. One mitochondrial and two nuclear loci were used to infer phylogenetic relationships among 70 Typoderus specimens, 52 of them from 22 geographically diversified Uluguru litter sifting samples. Various analyses consistently detected 11 geographically coherent Typoderus clades, six of them formed by the Uluguru specimens, where five are taxonomically interpreted as species: T. admetus sp.n., T. furcatus, T. peleus sp.n., T. polyphemus sp.n. and T. subfurcatus. The sixth Uluguru clade temporary named Typoderus sp. 1808 and consistently recovered with the different genetic markers comprises specimens morphologically similar to, and likely conspecific with, those of T. admetus sp.n. If so, then within the confined area of Uluguru forest (40 × 6 km) T. admetus sp.n. displays (i) high genetic differentiation without morphological change and (ii) high morphological variation with very little molecular differences; the driving factors of this phenomenon remain unknown. Observed distribution of Typoderus is interpreted as simple vicariance of a widespread ancestor; no evidence suggests a founder-based dispersal. This study rejects two widely assumed hypotheses that low dispersal (= flightless) forest-dependent clades are represented in each EAM block by an endemic species and that each such species within a single EAM block is panmictic.
‘Isolated Together’: Floor Signage in the Times of Pandemic and Partitioning of Our Common Spaces
Creators: name: Chevalier, Pauline
Publisher: name: img journal
Year: 2021

description: The current pandemic has seen the need to adorn public spaces with varied signage, sometimes almost spontaneous or, on the contrary, very elaborate, inviting us to respect distances and spaces specific to each person: what might seem obvious to us, however, refers to a long history of the notation of movement, on the ground or on the page. By comparing a few elements of current signage with a corpus of fencing and dance manuals, or even military treatises, the aim is to grasp the stakes of the visualization of this grid, intermediate and mediator of our relations, which isolates us together in a progressive process of incorporation of images and signs.

description: We examine whether the Painlevé property is a necessary condition for the integrability of nonlinear ordinary differential equations. We show that for a large class of linearisable systems this is not the case. In the discrete domain, we investigate whether the singularity confinement property is satisfied for the discrete analogues of the non-Painlevé continuous linearisable systems. We find that while these discrete systems are themselves linearisable, they possess nonconfined singularities.
