description: Layered tin monoxide (SnO) offers an exciting two-dimensional (2D) semiconducting system with great technological potential for next-generation electronics and photocatalytic applications. Using a combination of first-principles simulations and strain field analysis, this study investigates the structural dynamics of oxygen (O) vacancies in monolayer SnO and their functionalization by complementary lightweight dopants, namely C, Si, N, P, S, F, Cl, H and H$_{2}$. Our results show that O vacancies are the dominant native defect under Sn-rich growth conditions with active diffusion characteristics that are comparable to that of graphene vacancies. Depending on the choice of substitutional species and its concentration within the material, significant opportunities are revealed in the doped-SnO system for facilitating $n$/$p$-type tendencies, work function reduction, and metallization of the monolayer. N and F dopants are found to demonstrate superior mechanical compatibility with the host lattice, with F being especially likely to take part in substitution and lead to degenerately doped phases with high open-air stability. The findings reported here suggest that post-growth filling of O vacancies in Sn-rich conditions presents a viable channel for doping 2D tin monoxide, opening up new avenues in harnessing defect-engineered SnO nanostructures for emergent technologies.
Ravenne de la Zona dantesca à la Zona del silenzio
Creators: name: Renard, Thomas
Publisher: name: Opus Incertum
Year: 2021

description: Based on archival material and the available bibliography, this article traces the complex history of the area surrounding the tomb of Dante Alighieri and the Basilica of San Francesco in Ravenna. It focuses on the period running from the commemorations of the sixth centenary of Dante’s birth in 1865 to the inauguration of the Zona del silenzio in 1936. The end of the 19th century was marked by the failure of important monumental projects. The sixth centenary of Dante’s death in 1921 was the first important phase of transformation, seeking to recreate the appearance of a medieval past. Subsequently, during the Fascist period, several projects, notably those by Giulio Ulisse Arata and Gustavo Giovannoni, attempted to extend the intervention to the urban scale, which, through aborted projects and partial realisations, led to the creation of the Zona del Silenzio. Through the interplay of local and national actors and the key role of Corrado Ricci, the article analyses the difficulties of developing an area that symbolically embodies Italy’s tribute to the national poet.

description: We critically reexamine the problem of interatomic exchange interactions, which describe the total energy change caused by infinitesimal rotations of spins near some equilibrium state. For the small variations, such interactions can be always related to the response function. However, the form of this relation can depend on additional approximations. Particularly, the commonly used magnetic force theorem (MFT) prescribes the linear relation between the exchange interactions and the response function, while the exact theory requires this dependence to be inverse. We explore the origin and consequences of these differences in the definition for the wide class of materials: ferromagnetic Ni, antiferromagnetic NiO, half-metallic CrO2, multiferroic HoMnO3, and layered magnets CrCl3 and CrI3. While in most of these cases, MFT produces quite reasonable results and can be rigorously justifies in the long wavelength and strong-coupling limits, the exact formulation appears to be more consistent, especially in dealing with two important issues, which typically arise in the theory of exchange interactions: (i) the treatment of the ligand states, and (ii) the choice of the suitable variable for the description of infinitesimal rotations of spins. Both issues can be efficiently resolved by employing the ideas of adiabatic spin dynamics supplemented with the exact expression for the exchange interactions. Particularly, we propose a simple "downfolding" procedure for the elimination of the ligand spins by transferring their effect to the interaction parameters between the localized spins. Furthermore, we argue that the rotations of spin moments are more suitable for the description of low-energy excitations, while the rotations of the whole magnetization matrix cause much stronger perturbation in the system of spins.

description: The present report introduces the results of an extensive 3D laser measurement campaign with the objective of obtaining a precise raytracing model from point cloud data in an industrial environment. The measurements were conducted in a Bosch factory in Germany. The resulting model is tested with different raytracing tools and contrasted with multiband radio frequency measurements, simultaneously conducted in the same scenario. This raytracing model allows simulations with spatial consistency over the different bands of interest in 6G BRAINS, providing an accurate geometrical representation of the environment from the propagation properties for precise localization applications.

Unified Gauge Theories and Reduction of Couplings: from Finiteness to Fuzzy Extra Dimensions

description: Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified Theories, which can be made all-loop finite, both in the dimensionless (gauge and Yukawa couplings) and dimensionful (soft supersymmetry breaking terms) sectors. This remarkable property, based on the reduction of couplings at the quantum level, provides a drastic reduction in the number of free parameters, which in turn leads to an accurate prediction of the top quark mass in the dimensionless sector, and predictions for the Higgs boson mass and the supersymmetric spectrum in the dimensionful sector. Here we examine the predictions of two such FUTs. Next we consider gauge theories defined in higher dimensions, where the extra dimensions form a fuzzy space (a finite matrix manifold). We reinterpret these gauge theories as four-dimensional theories with Kaluza-Klein modes. We then perform a generalized a la Forgacs-Manton dimensional reduction. We emphasize some striking features emerging such as (i)the appearance of non-Abelian gauge theories in four dimensions starting from an Abelian gauge theory in higher dimensions, (ii) the fact that the spontaneous symmetry breaking of the theory takes place entirely in the extra dimensions and (iii) the renormalizability of the theory both in higher as well as in four dimensions. Then reversing the above approach we present a renormalizable four dimensional SU(N) gauge theory with a suitable multiplet of scalar fields, which via spontaneous symmetry breaking dynamically develops extra dimensions in the form of a fuzzy sphere $S^2_N$.

Study of hysteretic damping in small elastomeric structures
Creators: name: Mossman, Michele Ann
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the damping coefficient for silicone rubber micro structures under oscillating applied stresses. These small elastomeric structures are important to the development of Elastomeric Micro Electro Mechanical Systems, or EMEMS, which has recently become a field of interest. Since energy is lost in a damped system, it is generally desirable to minimize the effect of the damping. Although often overlooked, the primary mechanism of this damping results from the hysteresis effect. This complicated phenomenon cannot be described analytically, and it is a primary objective of this thesis to develop a computational algorithm to determine the hysteretic force based on a sequence of past displacements of the rubber. The extent of the damping can be determined by measuring the resonance response of a silicone structure when an oscillating displacement is applied. It is shown that these small silicone rubber structures exhibit the unique characteristic that the damping coefficient is independent of both the amplitude and frequency of the oscillation. This apparent independence of this damping coefficient of small silicone structures makes the use of the elastomer in EMEMS devices look promising. The ability to predict the effect of damping on the behaviour of these structures is crucial to device design, and its independence over a wide range of operating parameters bodes well for widespread use of elastomeric microstructures.

description: Augmenting a base constraint model with additional constraints can strengthen the inferences made by a solver and therefore reduce search effort. We focus on the automatic addition of streamliner constraints, derived from the types present in an abstract Essence specification of a problem class of interest, which trade completeness for potentially very significant reduction in search. The refinement of streamlined Essence specifications into constraint models suitable for input to constraint solvers gives rise to a large number of modelling choices in addition to those required for the base Essence specification. Previous automated streamlining approaches have been limited in evaluating only a single default model for each streamlined specification. In this paper we explore the effect of model selection in the context of streamlined specifications. We propose a new best-first search method that generates a portfolio of Pareto Optimal streamliner-model combinations by evaluating for each streamliner a portfolio of models to search and explore the variability in performance and find the optimal model. Various forms of racing are utilised to constrain the computational cost of training.

Lamb's problem for a half-space coupled to a generic distribution of oscillators at the surface

Subjects: subject: Applied Physics (physics.app-ph)

description: We propose an analytical framework to model the effect of single and multiple mechanical surface oscillators on the dynamics of vertically polarized elastic waves propagating in a semi-infinite medium. The formulation extends the canonical Lamb's problem, originally developed to obtain the wavefield induced by a harmonic line source in an elastic half-space, to the scenario where a finite cluster of vertical oscillators is attached to the medium surface. In short, our approach utilizes the solution of the classical Lamb's problem as Green's function to formulate the multiple scattered fields generated by the resonators. For an arbitrary number of resonators, arranged atop the elastic half-space in an arbitrary configuration, the displacement fields are obtained in closed-form and validated with numerics developed in a two-dimensional finite element environment.

description: Recently, the Fokker-Planck dynamics of particles in periodic potentials $\pm V$, have been investigated by using the matrix continued fraction method. It was found that the two periodic potentials, one being bistable and the other metastable give the same diffusion coefficient in the overdamped limit. We show that this result naturally follows from the fact that the considered potentials in the corresponding Schrödinger equation form supersymmetric partners. We show that these differing potentials ${\pm}V$ also exhibit symmetry in current and diffusion coefficients: $J_{+}(F)=-J_{-}(-F)$ and $D_{+}(F)=D_{-}(-F)$ in the presence of a constant applied force F. Moreover, we show numerically that the transport properties in these potentials are related even in the presence of oscillating drive.

The second argument is that there appears to be no infinite set of finite-dimensional Lie algebras (such as $su(N)$ for any $N$) that satisfies the algebraic structure of the membrane theory.

description: Fifteen years of research studies have concluded unanimously that spreadsheet errors are both common and non-trivial. Now we must seek ways to reduce spreadsheet errors. Several approaches have been suggested, some of which are promising and others, while appealing because they are easy to do, are not likely to be effective. To date, only one technique, cell-by-cell code inspection, has been demonstrated to be effective. We need to conduct further research to determine the degree to which other techniques can reduce spreadsheet errors.

We compute the $V$-filtration of the restriction of $f$ to any plane curve $C_t=g^{-1}(t)$ and show that the Gorenstein generator $dx\wedge dy/dg$ is a primitive form. Using results of A. Douai and C. Sabbah, we conclude that base space of the miniversal unfolding of $f_t:=f|_{C_t}$ is a Frobenius manifold. At the singular fibre $C_0$ we obtain a non-massive Frobenius manifold.

description: In this paper, we report 591 high velocity star candidates (HiVelSCs) selected from over 10 million spectra of the data release seven (DR7) of the Large Sky Area Multi-object Fiber Spectroscopic Telescope and the second Gaia data release, with three-dimensional velocities in the Galactic rest-frame larger than 445 km/s. We show that at least 43 HiVelSCs are unbound to the Galaxy with escape probabilities larger than 50%, and this number decreases to eight if the possible parallax zero-point error is corrected. Most of these HiVelSCs are metal-poor and slightly alpha-enhanced inner halo stars. Only 14% of them have [Fe/H] > -1, which may be the metal-rich "in situ" stars in halo formed in the initial collapse of the Milky Way or metal-rich stars formed in the disk or bulge but kinematically heated. The low ratio of 14% implies that the bulk of stellar halo was formed from the accretion and tidal disruption of satellite galaxies. In addition, HiVelSCs on the retrograde orbits have a slightly lower metallicities on average compared with these on the prograde orbits, meanwhile metal-poor HiVelSCs with [Fe/H] < -1 have an even faster mean retrograde velocity compared with metal-rich HiVelSCs. To investigate the origins of HiVelSCs, we perform orbit integrations and divide them into four types, i.e., hypervelocity stars, hyper-runaway stars, runaway stars and fast halo stars. A catalog for these 591 HiVelSCs, including radial velocities, atmospheric parameters, Gaia astrometric parameters, spatial positions, and velocities, etc., is available at http://paperdata.chinavo.org/LYB/lamostdr7_gaiadr2_hvs_591.csv.

description: In this paper, we show that method of mode identification using combined multicolour photometry and spectroscopy can be successfully applied to the pulsating subdwarf B star Balloon 090100001. The method constrains the spherical degree, l.We confirm that the dominant mode is radial and we show that for some other modes the method provides values of l consistent with the observed rotationally split triplet. Moreover, we derive a radius variation of 1.7 per cent for the dominant mode. The identification opens the possibility for constraining the internal structure of the star by means of seismic methods.

This essay consists of two parts: the first, by Emanuela Ferretti, investigates the context in which the project took shape, with particular regard to the Italian scenario of 1938-1939; the second, by Attilio Terragni, highlights – with the sensibility of the architect-designer – some of the characteristics of the Danteum project and is accompanied by reconstructive drawings of the building, made by the same author on the basis of original drawings by Giuseppe Terragni, preserved in the Terragni Archive in Como.

description: Vector meson degrees of freedom are incorporated into the Weinberg-Tomozawa (WT) meson-baryon chiral Lagrangian by using a scheme which relies on spin--flavor SU(6) symmetry. The corresponding Bethe-Salpeter approximation successfully reproduces previous SU(3)--flavor WT results for the lowest-lying s--wave negative parity baryon resonances, and it also provides some information on the dynamics of the heavier ones. Moreover, it also predicts the existence of an isoscalar spin-parity $\frac32^-$ $K^*N$ bound state (strangeness +1) with a mass around 1.7--1.8 GeV, unstable through $K^*$ decay. Neglecting d-wave KN decays, this state turns out to be quite narrow ($Γ\le 15$ MeV) and it might provide clear signals in reactions like $γp \to \bar K^0 p K^+π^-$ by looking at the three body $p K^+π^-$ invariant mass.

Leggere Dante “con le sexte, et con il regolo”

Publisher: name: Opus Incertum

description: The astronomical metaphors with which Dante in the Divine Comedy periodically provides the coordinates of his journey into the afterlife, suggest that the poet has materially drawn the cosmographic model of the afterworld by measuring the path taken on it, as pilots did during navigation. Renaissance commentators were certainly convinced of this, starting with Antonio di Tuccio Manetti, who around 1460 initiated a period of cosmographic studies on Dante’s hell that continued throughout the 16th century. The Florentine mathematician believed that to fully understand the architecture conceived by Dante in the womb of the Earth, it was necessary to have solid knowledge of geometry, arithmetic, cosmography and drawing. The globe, the nautical chart, the ruler and the compass were, therefore, the tools considered essential in order to give shape, size and location to the immense amphitheater of eternal damnation.

description: Because graphene is an atomically two-dimensional gapless semiconductor with nearly identical conduction and valence bands, graphene-based bilayers are attractive candidates for high-temperature electron-hole pair condensation. We present estimates which suggest that the Kosterlitz-Thouless temperatures of these two-dimensional counterflow superfluids can approach room temperature.

description: We study the acceleration and radiation of charged particles in the shock waves of supernova remnants using a recent version of the "box model". According to this, particles are accelerated in an energy-dependent region around the shock by the first order Fermi mechanism and lose energy through radiation. The particle distribution function is obtained from a spatially averaged kinetic equation that treats the energy losses self-consistently. There exists also a second population that consists of those particles that escape behind the shock where they also radiate. The energy distribution of this population is calculated in a similar manner. The application of the model to the supernova remnant RX J1713.7-3946, which was recently confirmed as a TeV source by H.E.S.S., shows that the X-ray emission can be attributed to electron synchrotron radiation while in gamma-rays there are contributions from both electrons and protons, with protons playing the dominant role. Additionally, there are strong indications that particles diffuse in turbulence that has a Kolmogorov spectrum.

Möglichkeiten Frau zu sein : Weiblichkeitsentwürfe im 19. Jahrhundert bei Louise Aston, Charlotte Birch-Pfeiffer und Louise von François
Creators: name: Mutter, Gisela
Publisher: name: University of British Columbia

description: The nineteenth century in Germany posed a repressive environment for-women as they were defined as inferior to men and forced into the subservient roles of housewives and mothers. This thesis examines the portrayal of femininity in three contemporary writers of the period, Louise Aston, Charlotte Birch-Pfeiffer and Louise von Francois. The first chapter endeavors to situate the writers in their social environment. It examines the mechanics that supported the patriarchal system, such as socializing women through education and categorizing them as inferior to justify and support their traditional roles. Chapters two, three, and four respectively deal with each author, presenting an introduction to their particular conditions and a brief summary of their lives. Following this, the individual tests are analyzed for their portrayal of femininity. These writers' visions of femininity differ greatly. Aston, whose career spanned the revolution of 1848, openly promotes liberal-humanist ideas and advocates the emancipation of women. Her heroines bear male an female traits and rise to positions of power and leadership. Birch-Pfeiffer's women are strong and independent. She frequently reverses the traditional gender roles. However, she upholds the moral code of her time, including the idea of the woman as exemplar of chastity and virtue . Francois idealizes the traditional role of women. However, she elevates that role by extolling motherhood and marital fidelity as supreme virtues. Despite these differences, there are similarities. All three writers offer an alternative picture of femininity despite this adherence, to a greater or lesser degree, to the traditional values of their time. In addition, they all criticize the patriarchal structures of society, revealing their discontent more or less openly. Finally, their portrayal of femininity was in each case based on their particular circumstances of the individual writers lives. Aston exploited the revolutionary times to present a strong claim for female emancipation; Birch- Pfeiffer, in need o f money, adapted strongly to the taste of her audience, finding in turn, interested recipients for her ideas; and Francois, a very private and proud person, chose to upgrade the women's role within the tradition, in attempt to avoid public attention. Within their circumstances, each one of the authors presented the best possible version of femininity as an alternative to traditional values.
“L’ardüa sua opra” (Par., XXXI, 34): Architectural Aspects of Dante’s Rome
Creators: name: Cachey, Theodore J.
name: Sbordoni, Chiara
Publisher: name: Opus Incertum
Year: 2021

description: The aim of this article is to examine the specifically architectural and structural aspects of Dante’s Rome in the Commedia which have not received particular attention in the critical literature. Focusing on the Eternal City’s monumental and urban features and their placement in the order of the poem at pivotal junctures in each of the three canticles, reveals how the city was for Dante, paradoxically, both central and liminal. While Rome is central to Dante’s political ideology, like the poem itself, the city is situated at the threshold between this world and the next. A key meta-architectural literary theme, Rome can serve as a point of departure for investigating the structure and status of the poem itself taken as an artifact fashioned in imitation of the divine architect: “Colui che volse il sesto a lo stremo del mondo, e dentro ad esso distinse tanto occulto e manifesto” (Par., XIX, 40-42).

L’architettura fiorentina ‘visibile’ a Dante (1265-1301) fra conservazione e progresso
Creators: name: Frati, Marco
Publisher: name: Opus Incertum
Year: 2021

description: The dialectic between tradition and innovation is undoubtedly a powerful engine of the creative process, which makes every discourse on Dante and his time always current. In the period between 1265 and 1301 the process for defining the identity of the city and the renewal of culture was underway in Florence. In those same years Dante and Arnolfo di Cambio were facing problems of language, just as the urban landscape was being subjected to a partial replacement and an apparently limitless progressive accumulation. The new public spaces favoured a reflection on the view of the buildings, which are imposing not only in terms of size or height, but also as a result of their measured and meditated relationship with the void that surrounds them. Most of the monumental buildings were conceived and built during the last years of the century, at the height of the Popolo regime. The focus is on the isolation and unity of public (palaces, prison) and religious (convents) complexes with the involvement of masters equipped with new instruments (drawing, tools) useful for design and executive control. The new conception of space and the relationship between public and private produces unprecedented solutions: straight and ‘perspective’ streets, entrance halls to palaces, vast unitary basilicas. The construction and renewal of small private buildings brought about the replacement of the stony and wooden image of the city with one softened by plaster, brick and greenery.

Dante e la figura dell’architetto
Creators: name: Tosco, Carlo
Publisher: name: Opus Incertum
Year: 2021

description: The essay explores the relationship between Dante and the professional figure of the architect. In his works, both in Latin and in vernacular, the poet rarely deals with architecture and never describes prominent personalities of architects, either from the ancient world or the Middle Ages. Using philological tools, the essay investigates an interesting passage from De monarchia, where Dante affirms the superiority of the architect over all other categories of artists. The research shows how Dante’s opinion was shared by contemporary scholars, while the literary image of the architect was widespread in the scholastic culture of 13th century.

description: We present a population synthesis study of NGC4435, an early-type Virgo galaxy interacting with NGC4438. We combine new spectroscopic observations obtained with the Spitzer Space Telescope IRS instrument with IRAC archival data and broad band data from the literature. The IRS spectrum shows prominent PAH features, low ionization emission lines and H_2 rotational lines arising from the dusty circumnuclear disk characterizing this galaxy. The central SED, from X-ray to radio, is well fitted by a model of an exponential burst superimposed on an old simple stellar population. From the lack of high excitation nebular lines, the [NeIII]15.5/[NeII]12.8 ratio, the temperature of molecular hydrogen, and the fit to the full X-ray to radio SED we argue that the present activity of the galaxy is driven by star formation alone. The AGN contribution to the ionizing flux is constrained to be less than 2%. The age of the burst is found to be around 190 Myr and it is fully consistent with the notion that the star formation process has been triggered by the interaction with NGC4438. The mass involved in the rejuvenation episode turns out to be less than 1.5% of the stellar galaxy mass sampled in a 5" central aperture. This is enough to render NGC4435 closely similar to a typical interacting early-type galaxy with inverted CaII[H+K] lines that will later turn into a typical cluster E+A galaxy and enforces the notion that these objects are the result of a recent rejuvenation episode rather than a genuine delayed formation.

description: The particle momentum anisotropy ($v_n$) produced in relativistic nuclear collisions is considered to be a response of the initial geometry or the spatial anisotropy $ε_n$ of the system formed in these collisions. The linear correlation between $ε_n$ and $v_n$ quantifies the efficiency at which the initial spatial eccentricity is converted to final momentum anisotropy in heavy ion collisions. We study the transverse momentum, collision centrality, and beam energy dependence of this correlation for different charged particles using a hydrodynamical model framework. The ($ε_n -v_n$) correlation is found to be stronger for central collisions and also for n=2 compared to that for n=3 as expected. However, the transverse momentum ($p_T$) dependent correlation coefficient shows interesting features which strongly depends on the mass as well as $p_T$ of the emitted particle. The correlation strength is found to be larger for lighter particles in the lower $p_T$ region. We see that the relative fluctuation in anisotropic flow depends strongly in the value of $η/s$ specially in the region $p_T <1$ GeV unlike the correlation coefficient which does not show significant dependence on $η/s$.

Architetture dell’aldilà: Dante, gli artisti, gli architetti
Creators: name: Battaglia Ricci, Lucia
Publisher: name: Opus Incertum
Year: 2021

description: The essay traces in greatly summarised form the history of the reception of Dante in the visual arts, focusing on the various ways in which painters, sculptors and architects have, through the ages, given visual substance to the peculiar physical and structural reality of Alighieri’s afterlife. The article offers a minimal survey of this production, identifying two historical periods in which the structure of the poem and the worlds invented by Alighieri are privileged with respect to the story of the pilgrim’s journey. The first phase, which went from the middle of the 15th century to the late 16th century, and involved scientists, intellectuals, painters, sculptors and architects, is already widely known. The essay summarises the essential data, opening up to almost forgotten drawings produced by anonymous artists at the beginning of the 16th century. The second phase has just begun and is still to be written. The essay considers a number of works produced by contemporary artists to illuminate how they look again at the structures created by Dante and use them as graphic supports of great symbolic value which are capable of representing and judging the present.
