The politics of domesticating the Eternal: the roadside shrines of Sicily
Creators: name: Waldeier Bizzarro, Tina
Publisher: name: Iconocrazia
Year: 2023
Subjects: Roadside shrines; ritual; Sicily; feste; Christian tradition

description: This contribution proposes a new interpretation of roadside shrines located in city streets, refusing to place them in the category of the Enlightenment philosopher David Hume, who had politicised devotion, distinguishing that exercised by the bourgeoisie from that of the vulgar. The study focuses on roadside shrines set up along certain alleys in Sicily. The reflection undertaken is indispensable for tracing the origin of those ritual behaviours, which are not only individual but also communitarian, with a shift in the paradigm of the social drama of ritual from structure to processes, emphasising how simple rustic altars are windows onto an inner world that opens up in society, going far beyond institutions and politics.

description: The interplay between the various measures of quantum correlations are well known in stable optical and electronic systems. Here, for the first time, we study such foundational issues in unstable quantum systems. Specifically we study meson-antimeson systems, which are produced copiously in meson factories. We use the semigroup formalism to compute the time evolution of several measures of quantum correlations for three meson systems (K-Kbar, Bd-Bdbar and Bs-Bsbar), circumventing difficulties which arise using other methods due to the instability of these particles. We then compare these measures to one another and find that the relations between them can be nontrivially different from those of their stable counterparts such as neutrinos.

description: Jean-Léon Gérôme was a French painter and sculptor, associated with numerous artistic movements (from Neo-Greek to Orientalism). This contribution offers a review of the author's works that portrayed Napoleon Bonaparte's experience in Egypt. The aim of the article is to demonstrate that Gérôme's work, contextualised in early 19th century France, and his choice to portray a general and emperor who traced profound changes in European History, is emblematic of art's capacity to transform power into image.

description: Phosphorus (P) is a major nutrient for plant growth and animal health, and its availability in soil is influenced by agronomic management and soil properties. This study examined the distribution of labile and non-labile soil P fractions in grassland and the properties that influence their distribution in temperate grasslands. Eleven fractions were identified as, labile (H2O.P and NaHCO3 .P), moderately labile (NaOH.P) and plant non-available (NaOH.P, HCl.P and residual P). The residual P, moderately labile organic (NaOH.Po) and inorganic (NaOH.Pi) fractions comprised 38%, 24% and 15% of the total P (TP), respectively. The residual and organic (Po) fractions were associated with extractable Fe, and the NaOH.Pi fraction was associated with extractable Al. Agronomic reagents (Morgan’s and Mehlich3) targeted specific fractions based on their affinity for different soil elements. Morgan’s P was associated with extractable and residual Ca and in high Ca soils, and over estimated plant-available P by extracting non-labile Ca.P forms (HCl.P). The Mehlich3 P test was associated with NaOH.Pi fraction and showed a preference for Al.P oxides. This study indicates that Mehlich3 reagent, which provides a wider suite of elements such as P, Ca, Al and Fe, will suit as a better indicator for soil P dynamics and improved P advice to farmers. The inclusion of additional soil chemico-physical characteristics would improve agronomic soil testing, benefitting farmers’ advice.

description: “The Newsroom” di Aroon Sorkin (Hbo, 2012-2014) si è guadagnata uno spazio di rilievo nella “golden age” delle serie tv mettendo in scena la resistenza della redazione di un grande network contro l'esasperazione della competizione giornalistica e il suo sbocco verso un crescente integrazione tra informazione e intrattenimento. Il paper analizza temi, testi e personaggi principali per inquadrare la fase storica dell'impatto tra nuovi media e televisione commerciale. In un'epoca di invocata disintermediazione, la serie instilla degli interrogativi nel selezionato pubblico di Hbo: il giornalismo va superato o piuttosto rivendicato? L'opinione pubblica è davvero più libera, se abbandonata al flusso di informazioni senza mediazione professionale? “The Newsroom” by Aroon Sorkin (Hbo, 2012-2014) has earned a prominent space in the "golden age" of TV series by staging the resistance of a large network newsroom against the exasperation of the news competition and its outcome towards a growing integration between information and entertainment. The paper analyses themes, texts and characters from the series to frame the anomic phase of the impact between new and heritage media. In an age of invoked disintermediation, the series generates some doubts in the selected Hbo audience: should journalism be overcome or rather reclaimed? Is public opinion really freer if abandoned to the flow of information without any professional mediation?

description: Quenched galaxies at z>2 are nearly all very compact relative to z~0, suggesting a physical connection between high stellar density and efficient, rapid cessation of star-formation. We present restframe UV spectra of Lyman-break galaxies (LBGs) at z~3 selected to be candidate progenitors of quenched galaxies at z~2 based on their compact restframe optical sizes and high surface density of star-formation. We compare their UV properties to those of more extended LBGs of similar mass and star formation rate (non-candidates). We find that candidate progenitors have faster ISM gas velocities and higher equivalent widths of interstellar absorption lines, implying larger velocity spread among absorbing clouds. Candidates deviate from the relationship between equivalent widths of Lyman-alpha and interstellar absorption lines in that their Lyman-alpha emission remains strong despite high interstellar absorption, possibly indicating that the neutral HI fraction is patchy such that Lyman-alpha photons can escape. We detect stronger CIV P-Cygni features (emission and absorption) and HeII emission in candidates, indicative of larger populations of metal rich Wolf-Rayet stars compared to non-candidates. The faster bulk motions, broader spread of gas velocity, and Lyman-alpha properties of candidates are consistent with their ISM being subject to more energetic feedback than non-candidates. Together with their larger metallicity (implying more evolved star-formation activity) this leads us to propose, if speculatively, that they are likely to quench sooner than non-candidates, supporting the validity of selection criteria used to identify them as progenitors of z~2 passive galaxies. We propose that massive, compact galaxies undergo more rapid growth of stellar mass content, perhaps because the gas accretion mechanisms are different, and quench sooner than normally-sized LBGs at these early epochs.

description: Das Thema der vorliegenden Masterarbeit ist die Vermittlung des wissenschaftlichen Schreibens im Kontext der Universität Wien. Im theoretischen Teil der Arbeit geht es um wissenschaftliches Schreiben, die Wissenschaftssprache als Forschungsgegenstand und Schreibdidaktik an der Hochschule. Außerdem wird das Feld des wissenschaftlichen Schreibens an der Universität Wien beleuchtet. Diese Ausführungen bilden den theoretischen Rahmen für eine empirische Studie, bei der untersucht wird, welche Einstellungen Lehrende, die Proseminare an der Universität Wien leiten bzw. geleitet haben, zur Vermittlung von wissenschaftlichem Schreiben haben und wie sich diese auf ihre Lehre auswirken. Zur Beantwortung dieser Fragestellung wurden Interviews mit fünf Lehrenden geführt, die anschließend anhand der qualitativen Inhaltsanalyse nach Kuckartz (2018) ausgewertet wurden. Bei der Auswertung und Analyse der erhobenen Daten konnte festgestellt werden, dass die Lehrenden das wissenschaftliche Schreiben als lernbar betrachten. Weiters sehen die Lehrenden den Erwerb wissenschaftlicher Schreibkompetenzen als Prozess, der an der Universität begleitet werden sollte, sofern die Rahmenbedingungen das ermöglichen. Die Einstellung, dass Schreiben gelehrt und gelernt werden sollte, führt dazu, dass die Vermittlung des wissenschaftlichen Schreibens einen relevanten Teil in den Proseminaren der Lehrenden einnimmt. Dies geschieht prozessorientiert und eingebettet in die jeweiligen Proseminare, sodass fachliche Inhalte und wissenschaftliches Schreiben in Kombination gelehrt und gelernt werden.

Attraverso un’analisi ‘iconocratica’ basata su un repertorio fotografico dell’Albania degli anni Zero l’Autore propone un’immagine dell’Albania contemporanea in cui convivono le molteplici componenti ed eredità culturali del paese, viene perseguita una peculiare via alla modernizzazione e si assiste a una trasformazione cromatica dello spazio urbano della capitale. The essay analyses Albanian identity, starting from long-term legacies (the Illyrians, Skanderberg, the Ottoman Empire, etc.), focusing on the transition from the communist regime to a complex process of democratisation. By means of an 'iconocratic' analysis based on a photographic repertoire of Albania in the 1990s, the author proposes an image of contemporary Albania in which the country's multiple cultural components and heritages coexist, a peculiar path to modernisation is pursued, and a chromatic transformation of the capital's urban space is witnessed.

By appropriately tuning the DFG in the strong Rashba coupling regime, resonant state structures in conductance can be found that is sensitive to the length of the DFG system. Furthermore, a hole-like bound state feature below the RZ gap and an electron-like quasi-bound state feature at the threshold of the upper spin branch can be found that is insensitive to the length of the DFG system.

description: We investigate certain finiteness questions that arise naturally when studying approximations modulo prime powers of p-adic Galois representations coming from modular forms. We link these finiteness statements with a question by K. Buzzard concerning p-adic coefficient fields of Hecke eigenforms. Specifically, we conjecture that for fixed N, m, and prime p with p not dividing N, there is only a finite number of reductions modulo p^m of normalized eigenforms on Γ_1(N). We consider various variants of our basic finiteness conjecture, prove a weak version of it, and give some numerical evidence.

description: Starting from second order around thermal equilibrium, the response of a statistical mechanical system to an external stimulus is not only governed by dissipation and depends explicitly on dynamical details of the system. The so called frenetic contribution in second order around equilibrium is illustrated in different physical examples, such as for non-thermodynamic aspects in the coupling between system and reservoir, for the dependence on disorder in dielectric response and for the nonlinear correction to the Sutherland--Einstein relation. More generally, the way in which a system's dynamical activity changes by the pertubation is visible (only) from nonlinear response.

description: Chronic Opisthorchis viverrini-induced hepatobiliary disease is associated with significant leukocyte infiltration, including activated macrophages; however, the polarization of infiltrating macrophages remains to be fully characterized. In this study, we characterized macrophage polarization and phenotype in chronic O. viverrini-induced hepatobiliary disease in humans and hamsters using gene expression and histochemical analysis. Chronic O. viverrini infection and associated hepatobiliary diseases were associated with iron loaded M2-like macrophages in both humans and hamsters. This study provides suggestive evidence that iron loaded M2-like macrophages promote hepatobiliary disease in chronic O. viverrini infection.

Luminous Blue Variables are Antisocial: Their Isolation Implies that they are Kicked Mass Gainers in Binary Evolution

description: Based on their relatively isolated environments, we argue that LBVs must be primarily the product of binary evolution, challenging the traditional single-star view wherein LBVs mark a brief transition between massive O stars and Wolf-Rayet (WR) stars. If the latter were true, then LBVs should be concentrated in young clusters and found alongside main-sequence stars with similarly high inferred initial mass. This is decidedly not the case. Examining locations of LBVs compared to O stars in our Galaxy and the Magellanic Clouds reveals that LBVs systematically avoid clusters of O stars, and many reside over 100 pc from any O star. In the LMC, LBVs are statistically much more isolated than O-type stars, and (perhaps most surprisingly) even more isolated than most WR stars. This makes it impossible for LBVs to be massive stars in transition to WR stars. Instead, we propose that massive stars and supernova (SN) subtypes are dominated by bifurcated evolutionary paths in interacting binaries, wherein most WR stars and SNeIbc correspond to the mass donors, while LBVs (and their lower-mass analogs like B[e] supergiants, which we show to be even more isolated) are the mass gainers. LBVs are essentially the late evolutionary stage of massive blue stragglers. Through binary mass transfer, rejuvinated mass gainers get enriched, spun up, and sometimes kicked far from their clustered birthsites by their companion's SN. This scenario agrees better with LBVs exploding as SNeIIn and the observed isolation of SNe~IIn and SN impostors. We argue that environmental trends of various SN subtypes are influenced more by binarity and SN kicks, rather than tracing initial mass as is generally assumed. Mergers or Thorne-Zykow objects might also give rise to LBVs, but these scenarios may have a harder time explaining why LBVs avoid clusters.

Classical interactions of the instanton-dyons with antidyons

description: Instanton-dyons, also known as instanton-monopoles or instanton-quarks, are topological constituents of the instantons at nonzero temperature and nonzero expectation value of $A_4$. While the interaction between instanton-dyons has been calculated to one-loop order by a number of authors, that for dyon-antidyon pairs remains unknown even at the classical level. In this work we are filling this gap, by solving the gradient flow equation on a 3d lattice. We start with two well separated objects. We find that, after initial rapid relaxation, the configurations follow "streamline" set of configurations, which is basically independent on the initial configurations used. In striking difference to instanton-antiinstanton streamlines, in this case it ends at a quasi-stationary configuration, with an abrupt drop to perturbative fields. We parameterize the action of the streamline configurations, which is to be used in future many-body calculations.

description: We introduce and study an adaptive finite element method for the Stokes system based on an Uzawa outer iteration to update the pressure and an elliptic adaptive inner iteration for velocity. We show linear convergence in terms of the outer iteration counter for the pairs of spaces consisting of continuous finite elements of degree 푘 for velocity whereas for pressure the elements can be either discontinuous of degree 푘-1 or continuous of degree 푘-1 and 푘. The popular Taylor-Hood family is the sole example of stable elements included in the theory, which in turn relies on the stability of the continuous problem and thus makes no use of the discrete inf-sup condition. We discuss the realization and complexity of the elliptic adaptive inner solver, and provide consistent computational evidence that the resulting meshes are quasi-optimal.

description: We report the optimisation of optical properties of single defects in three-dimensional (3D) face-centred-cubic (FCC) woodpile photonic crystal (PC) cavities by using plane-wave expansion (PWE) and finite-difference time-domain (FDTD) methods. By optimising the dimensions of a 3D woodpile PC, wide photonic band gaps (PBG) are created. Optical cavities with resonances in the bandgap arise when point defects are introduced in the crystal. Three types of single defects are investigated in high refractive index contrast (Gallium Phosphide-Air) woodpile structures and Q-factors and mode volumes ($V_{eff}$) of the resonant cavity modes are calculated. We show that, by introducing an air buffer around a single defect, smaller mode volumes can be obtained. We demonstrate high Q-factors up to 700000 and cavity volumes down to $V_{eff}<0.2(λ/n)^3$. The estimates of $Q$ and $V_{eff}$ are then used to quantify the enhancement of spontaneous emission and the possibility of achieving strong coupling with nitrogen-vacancy (NV) colour centres in diamond.

description: Infection is an important cause of stillbirth world-wide; in low and middle income countries (LMICs), 50% or more are likely caused by infection. In contrast, in high income countries, only10-25% of stillbirths are caused by infection. Syphilis, where prevalent, causes the majority of infectious stillbirths and is the infection most amenable to screening and treatment. Ascending bacterial infection is a common cause of stillbirth, but prevention has proven elusive. Many viral infections are causal for stillbirth but aside from vaccination for common childhood diseases, it is unclear how most viral-caused stillbirths may be prevented. Malaria, because of its high prevalence and extensive placental damage accounts for large numbers of stillbirths. Intermittent malarial prophylaxis and insecticide impregnated bed nets should decrease stillbirths. Many animal and vector-borne infections cause stillbirth. Because this relationship is especially important in LMICs, research that more clearly defines this relationship is crucial to reduce the unacceptably high stillbirth rates in those areas.

description: We study the scalar condensation of a general holographic superconductor model in AdS black hole background away from the probe limit. We find the model parameters together with the scalar mass and backreaction can determine the order of phase transitions completely. In addition, we observe two types of discontinuities of the scalar operator in the case of first order phase transitions. We analyze in detail the effects of the scalar mass and backreaction on the formation of discontinuities and arrive at an approximate relation between the threshold model parameters. Furthermore, we obtain superconductor solutions corresponding to higher energy states and examine the stability of these superconductor solutions.

We rely on the procedure recently described by Donos and Gauntlett in the context of Q-lattices and holographic models where momentum dissipation is realized through non-trivial scalars. The analytical approach confirms the results found previously by means of numerical computations.

description: Analysis of cosmic microwave background radiation fluctuations favors an effective number of neutrinos, $N_ν>3$. This motivates a reinvestigation of the neutrino freeze-out process. Here we characterize the dependence of $N_ν$ on the Standard Model (SM) parameters that govern neutrino freeze-out. We show that $N_ν$ depends on a combination $η$ of several natural constants characterizing the relative strength of weak interaction processes in the early Universe and on the Weinberg angle $\sin^2θ_W$. We determine numerically the dependence $N_ν(η,\sin^2θ_W)$ and discuss these results. The extensive numerical computations are made possible by two novel numerical procedures: a spectral method Boltzmann equation solver adapted to allow emerging chemical non-equilibrium, and a method to evaluate Boltzmann equation collision integrals that generates a smooth integrand.

description: In this paper, we propose a simple methodology to select a limited number of geographical areas to prioritize for commodity-specific investments in Uganda. Similar to other approaches for prioritizing investments geographically, the basic idea behind the proposed method is that districts with high agro-ecological potential, that are also far from their potential and have high levels of poverty, should be prioritized for commodity-specific investments as they are where investments are likely to have the highest impact. The methodology then proposes an iterative elimination algorithm to provide a list of suggested districts that rank high in all dimensions. The results highlight that prioritized districts are very context and commodity specific. In certain cases (e.g. sugar cane or millet), prioritized districts tend to be highly concentrated in one geographical region, whereas they tend to be more spread out for the sectors producing other commodities (i.e. bananas, coffee, goats, cassava and maize). The results are expected to inform a discussion with policymakers in Uganda which is expected to culminate in the selection of an even narrower set of districts for which more in-depth analyses of commodity-specific investments will be undertaken at the level of priority areas, including, among others, irrigation, mechanization, seeds and fertilizers.

description: Heisenberg's uncertainty principle results in one of the strangest quantum behaviors: an oscillator can never truly be at rest. Even in its lowest energy state, at a temperature of absolute zero, its position and momentum are still subject to quantum fluctuations. Resolving these fluctuations using linear position measurements is complicated by the fact that classical noise can masquerade as quantum noise. On the other hand, direct energy detection of the oscillator in its ground state makes it appear motionless. So how can we resolve quantum fluctuations? Here, we parametrically couple a micromechanical oscillator to a microwave cavity to prepare the system in its quantum ground state and then amplify the remaining vacuum fluctuations into real energy quanta. Exploiting a superconducting qubit as an artificial atom, we measure the photon/phonon-number distributions during these optomechanical interactions. This provides an essential non-linear resource to, first, verify the ground state preparation and second, reveal the quantum vacuum fluctuations of the macroscopic oscillator's motion. Our results further demonstrate the ability to control a long-lived mechanical oscillator using a non-Gaussian resource, directly enabling applications in quantum information processing and enhanced detection of displacement and forces.

description: A recent neutron interferometry experiment claims to demonstrate a paradoxical phenomena dubbed the "quantum Cheshire Cat" \cite{Denkmayr2014}. We have reproduced and extended these results with an equivalent optical interferometer. The results suggest that the photon travels through one arm of the interferometer, while its polarization travels through the other. However, we show that these experimental results belong to the domain where quantum and classical wave theories coincide; there is nothing uniquely quantum about the illusion of this cheshire cat.

description: Superconductivity in Iron-Arsenic based pnictides emerges in close proximity to an antiferromagnetic (AFM)ordered parent state and the AFM phase overlaps with superconducting (SC) phase in some pnictides for certain range of doping. CaFe2-xNixAs2 belongs to this category, where both the phases overlap. Here we use scanning tunneling microscopy and spectroscopy to investigate the local electronic properties of uderdoped CaFe1.96Ni0.04As2 single crystals in the vicinity of the boundary of the two phases. Both resistivity and magnetic measurements show that a tiny portion (~ 1.2 %) of this compound becomes superconductor below the SC onset temperature TC ~ 15 K. Topographic images show reasonably flat surface with signatures of atomic resolution. High temperature spectra are spatially homogeneous and show signatures of spin density wave (SDW) gap with a finite density of states near the Fermi energy. Below TC, spectra show significant spatial inhomogeneity with a SDW gap everywhere but at some locations we also see an asymmetric or symmetric depression in ~ +/- 5 meV energy range together with the SDW gap. Inhomogeneity reduces significantly as the temperature goes above TC and disappears completely far above TC. These observations are discussed in terms of an inhomogeneous electronic phase that may exist due to the vicinity of this composition to the SC dome boundary on the underdoped side of the phase diagram.

description: Evidence from Europe, Asia, and North America suggests that standard three-drug regimens of a proton pump inhibitor plus amoxicillin and clarithromycin are significantly less effective for eradicating Helicobacter pylori (H. pylori) infection than five-day concomitant and ten-day sequential four-drug regimens that include a nitroimidazole. These four-drug regimens also entail fewer antibiotic doses and thus may be suitable for eradication programs in low-resource settings. Studies are limited from Latin America, however, where the burden of H. pylori-associated diseases is high.

description: This article carries out a qualitative analysis on a system of integral equations of the Hardy--Sobolev type. Namely, results concerning Liouville type properties and the fast and slow decay rates of positive solutions for the system are established. For a bounded and decaying positive solution, it is shown that it either decays with the slow rates or the fast rates depending on its integrability. Particularly, a criterion for distinguishing integrable solutions from other bounded and decaying solutions in terms of their asymptotic behavior is provided. Moreover, related results on the optimal integrability, boundedness, radial symmetry and monotonicity of positive integrable solutions are also established. As a result of the equivalence between the integral system and a system of poly-harmonic equations under appropriate conditions, the results translate over to the corresponding poly-harmonic system. Hence, several classical results on semilinear elliptic systems are recovered and further generalized.

description: We have entered a new era in HIV prevention whereby priorities have expanded from biomedical discovery to include implementation, effectiveness, and the effect of combination prevention at the population level. However, gaps in knowledge and implementation challenges remain. In this Review we analyse trends in the rapidly changing landscape of HIV prevention, and chart a new path for HIV prevention research that focuses on the implementation of effective and efficient combination prevention strategies to turn the tide on the HIV pandemic.

description: This paper assesses the food security impacts of widespread agricultural interventions, aiming at increasing agricultural yields, and explores the role played by adjustments in rural households’ livelihood strategies in mediating those impacts. Our empirical strategy combines project and remote-sensing data with a household panel survey and exploits the timing and geographic variation in the roll-out of interventions implemented from 2011 to 2016 by the Ethiopian Agricultural Transformation Agency (ATA), recently renamed as Agricultural Transformation Institute (ATI). Results show that agricultural interventions are effectively associated with higher agricultural yields, better food security outcomes and adjustments in livelihood strategies. However, when exploring the role of livelihood strategies through a Causal Mediation Analysis, we show that livelihood adjustments do not seem to play any mediating role in food security impacts. Heterogeneity analysis suggests that the absence of a mediating role stems from agricultural interventions affecting different types of households differently: the most vulnerable households primarily benefited through food security improvements while more-endowed households adjusted their livelihood strategies.

Cutoff for the noisy voter model

description: Given a continuous time Markov Chain $\{q(x,y)\}$ on a finite set $S$, the associated noisy voter model is the continuous time Markov chain on $\{0,1\}^S$, which evolves in the following way: (1) for each two sites $x$ and $y$ in $S$, the state at site $x$ changes to the value of the state at site $y$ at rate $q(x,y)$; (2) each site rerandomizes its state at rate 1. We show that if there is a uniform bound on the rates $\{q(x,y)\}$ and the corresponding stationary distributions are almost uniform, then the mixing time has a sharp cutoff at time $\log|S|/2$ with a window of order 1. Lubetzky and Sly proved cutoff with a window of order 1 for the stochastic Ising model on toroids; we obtain the special case of their result for the cycle as a consequence of our result. Finally, we consider the model on a star and demonstrate the surprising phenomenon that the time it takes for the chain started at all ones to become close in total variation to the chain started at all zeros is of smaller order than the mixing time.

description: HIV transmission risk during acute and early HIV infection (EHI) is sharply elevated, but the contribution of EHI to ongoing HIV transmission is controversial. However, in settings where EHI contributes substantially to secondary transmissions, early diagnosis and intervention may be critical for HIV prevention. We estimated the contribution of EHI to HIV incidence in Lilongwe, Malawi and predicted the future impact of hypothetical prevention interventions affecting EHI only, chronic HIV infection (CHI) only, or both stages.
