description: In this short note, we prove that a bi-invariant Riemannian metric on $\mathrm{Sp}(n)$ is uniquely determined by the spectrum of its Laplace-Beltrami operator within the class of left-invariant metrics on $\mathrm{Sp}(n)$. In other words, on any of these compact simple Lie groups, every left-invariant metric which is not right-invariant cannot be isospectral to a bi-invariant metric. The proof is elementary and uses a very strong spectral obstruction proved by Gordon, Schueth, and Sutton.

The Work of Art in a Pragmatist Perspective, between Somaesthetics and Techno-aesthetics

description: John Dewey puts aesthetic experience at the center of his reflection on art and beauty, reconsidering it dynamically. Nowadays, this view opened the path to somaesthetics, a term coined by Richard Shusterman, and aesthetic anthropology. Here, it is argued that the contribution of pragmatist aesthetics could be further developed by exploring its analogies with techno-aesthetics, a paradigm proposed by French philosopher Gilbert Simondon in the early 1980s. Art occupies accordingly a special place within the different forms of aesthetic experience, being considered as a way of experimenting the impact of new technologies in the human experience. It is a process by which technologies create ‘devices’ for experimenting perception and reflection: namely, ways of reconstructing the nature of the human mind in-between body and technology, and by means of their interaction. Cinema reconsidered after Dewey’s fellow George H. Mead, offers an exemplary case as both artistic and technological devices.

description: The aim of this paper is to reconsider the relationship between living body and artefacts in the perspective of Helmuth Plessner’s aesthesiology. According to the outcomes of Plessner’s aesthesiology, I present two main theses: 1) artefacts are not created, but rather discovered (entdeckt) and expressed by human agency, and 2) the bodily dimension of the human being is the condition of the “discovery” of material and symbolic artefacts. To argue these theses I highlight a) the process of “somatisation” that engages the Kantian transcendental model of subject in Plessner’s philosophical anthropology, b) Plessner’s rejection of the Kantian profile of Uexküll’s theory of Umwelt as an application of this transcendental model of subjectivity in the biological field, and c) the development in Plessner of a type of transcendental aesthetics, which can be linked with S. Crowell’s recent theory of perception.

The technical object and somatic thought
Creators: name: Grespi, Barbara
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2019

description: This essay explores the lines of thought focused on the relationship between gesture and technique, examining the theories which have conceptualized the transfer of gestural matrices into inert matter, and understood technique as a result of this process. Although associated mainly with the writings of the palaeontologist André Leroi-Gourhan, this thought actually predates his work, and consists of multiple branches: having first taken root at the end of the nineteenth century, it became diffused throughout the following decades in different forms. These nevertheless shared a constant reference to cinema, both as a privileged place that captures gestures, and as a technique that can absorb their quintessence. From Espinas to Simondon, via Jousse and Eisenstein, the theory of gestural transmission breaks down various polarities, such as body and environment, organic and inorganic, animated and inanimate, performativity and inner life. It foregrounds the imaginative logic of the body and the many forms of somatic thinking developed by man. Such forms lie at the heart of the creative processes and have found their highest appreciation in cinema, as a machine that, from its very origins, has been grafted not only on the eye but on the whole body.

Technical Creativity, Material Engagement and the (Controversial) Role of Language

description: For several hundred thousand years, the genus homo deployed a characteristic technical creativity, communicating and transmitting its outcomes, together with its operative protocols, without the available recourse to articulated language. The thesis proposed here is that the aforementioned functions should be attributed to a complex intertwining of embodied abilities, which can in turn be ascribed to the classic philosophical concept of imagination. It is through imagination that the human becomes involved in material engagement (Malafouris), by virtue of which its extended mind takes part in the processes of producing artifacts and is in turn shaped by them. The main issue of this article consists in investigating how this involvement occurs (§§ 1 and 2) and the part that articulated language plays in it, following the invention of the latter (§§ 3 and 4). The latter’s emergence can indeed be traced back to the transformation and specialization of a recursive element, already present in the pre-linguistic work of imagination, whose ability to implement a denotative semantics is discussed in particular (§ 5).

description: The mass and spin properties of binary black holes (BBHs) inferred from their gravitational-wave signatures reveal important clues about how these systems form. BBHs originating from isolated binary evolution are expected to have spins preferentially aligned with their orbital angular momentum, whereas there is no such preference in binaries formed via dynamical assembly. The fidelity with which near-future gravitational-wave detectors can measure off-axis spins will have implications for the study of BBH formation channels. In this work, we examine the degree to which the Advanced LIGO Plus (A+) and Advanced Virgo Plus (AdV+) interferometric detectors can measure both aligned and misaligned spins. We compare spin resolution between the LIGO-Virgo network operating at either A+/AdV+ ("Plus") sensitivity or Advanced-era design ("Design") sensitivity using simulated BBH gravitational-wave signals injected into synthetic detector noise. The signals are distributed over the mass-spin parameter space of likely BBH systems, accounting for the effects of precession and higher-order modes. We find that the Plus upgrades yield significant improvements in spin estimation for systems with unequal masses and moderate or large spins. Using simulated signals modelled after different types of hierarchical BBH mergers, we also conclude that the Plus detector network will yield substantially improved spin estimates for 1G+2G binaries compared to the Design network.

description: We unveil an unexpected non-Hermitian phenomenon, dubbed edge burst, in non-Hermitian quantum dynamics. Specifically, in a class of non-Hermitian quantum walk in periodic lattices with open boundary condition, an exceptionally large portion of loss occurs at the system boundary. The physical origin of this edge burst is found to be an interplay between two unique non-Hermitian phenomena: non-Hermitian skin effect and imaginary gap closing. Furthermore, we establish a universal bulk-edge scaling relation underlying the non-Hermitian edge burst. Our predictions are experimentally accessible in various non-Hermitian systems including quantum-optical and cold-atom platforms.

description: Die biologische Grundlage erfolgreicher motorischer Rehabilitation nach Schädigungen des Nervensystems ist die neuronale Plastizität des Gehirns. Unter dem Begriff der neuronalen Plastizität werden jene strukturellen und funktionellen Anpassungen des Gehirns verstanden, die sich aufgrund von Veränderungen in der Umwelt und nach Schädigungen des Gehirns ergeben können. Plastische Veränderungen im Gehirn sind durch Verhaltensänderung, Training und Lernen lebenslang möglich. Sie basieren vor allem auf einer Veränderung der Verbindungsstärke vonNervenzellen untereinander. Die Forschungsergebnisseder letzten Jahre zeigen zudem, dass je nach Größe und Lokalisation einer Schädigung unterschiedliche Mechanismen neuronaler Plastizität dazu beitragen, dass das Nervensystem auf beeindruckende Weise funktionelle Ausfälle kompensiert.

description: We consider the problem of scheduling to minimize mean response time in M/G/1 queues where only estimated job sizes (processing times) are known to the scheduler, where a job of true size $s$ has estimated size in the interval $[βs, αs]$ for some $α\geq β> 0$. We evaluate each scheduling policy by its approximation ratio, which we define to be the ratio between its mean response time and that of Shortest Remaining Processing Time (SRPT), the optimal policy when true sizes are known. Our question: is there a scheduling policy that (a) has approximation ratio near 1 when $α$ and $β$ are near 1, (b) has approximation ratio bounded by some function of $α$ and $β$ even when they are far from 1, and (c) can be implemented without knowledge of $α$ and $β$? We first show that naively running SRPT using estimated sizes in place of true sizes is not such a policy: its approximation ratio can be arbitrarily large for any fixed $β< 1$. We then provide a simple variant of SRPT for estimated sizes that satisfies criteria (a), (b), and (c). In particular, we prove its approximation ratio approaches 1 uniformly as $α$ and $β$ approach 1. This is the first result showing this type of convergence for M/G/1 scheduling. We also study the Preemptive Shortest Job First (PSJF) policy, a cousin of SRPT. We show that, unlike SRPT, naively running PSJF using estimated sizes in place of true sizes satisfies criteria (b) and (c), as well as a weaker version of (a).

description: We discuss the generic properties of a general, smoothly varying, spherically symmetric mass distribution $\mathcal{D}(r,θ)$, with no cosmological term ($θ$ is a length scale parameter). Observing these constraints, we show that (a) the de Sitter behavior of spacetime at the origin is generic and depends only on $\mathcal{D}(0,θ)$, (b) the geometry may posses up to $2(k+1)$ horizons depending solely on the total mass $M$ if the cumulative distribution of $\mathcal{D}(r,θ)$ has $2k+1$ inflection points, and (c) no scalar invariant nor a thermodynamic entity diverges. We define new two-parameter mathematical distributions mimicking Gaussian and step-like functions and reduce to the Dirac distribution in the limit of vanishing parameter $θ$. We use these distributions to derive in closed forms asymptotically flat, spherically symmetric, solutions that describe and model a variety of physical and geometric entities ranging from noncommutative black holes, quantum-corrected black holes to stars and dark matter halos for various scaling values of $θ$. We show that the mass-to-radius ratio $πc^2/G$ is an upper limit for regular-black-hole formation. Core--multi-shell and multi-shell regular black holes are also derived.

Universal Dephasing Mechanism of Many-Body Quantum Chaos

description: Ergodicity is a fundamental principle of statistical mechanics underlying the behavior of generic quantum many-body systems. However, how this universal many-body quantum chaotic regime emerges due to interactions remains largely a puzzle. This paper demonstrates using both heuristic arguments and a microscopic calculation that a dephasing mechanism, similar to Altshuler-Aronov-Khmelnitskii dephasing in the theory of localization, underlies this transition to chaos. We focus on the behavior of the spectral form factor (SFF) as a function of "time", t, which characterizes level correlations in the many-body spectrum. The SFF can be expressed as a sum over periodic classical orbits and its behavior hinges on the interference of trajectories related to each other by a time translation. In the absence of interactions, time-translation symmetry is present for each individual particle, which leads to a fast exponential growth of the SFF and correspondingly loss of correlations between many-body levels. Interactions lead to dephasing, which disrupts interference, and breaks the massive time-translation symmetry down to a global time-translation/energy conservation. This in turn gives rise to the hallmark linear-in-$t$ ramp in the SFF reflecting Wigner-Dyson level repulsion. This general picture is supported by a microscopic analysis of an interacting many-body model. Specifically, we study the complex $\mbox{SYK}_2+\mbox{SYK}_2^2$ model, which allows to tune between an integrable and chaotic regime. It is shown that the dephasing mass vanishes in the former case, which maps to the non-interacting $\mbox{SYK}_2$ model via a time reparameterization. In contrast, the chaotic regime gives rise to dephasing, which suppresses the exponential ramp of the non-interacting theory and induces correlations between many-body levels.

description: Through an eigenanalysis of small perturbations, as typically done in small-signal stability studies, we intend to discover the underlying reasons that make those perturbations propagate in some way or another in the grid. To this end, we establish connections between the perturbations time-scale and topological metrics. Namely, the algebraic connectivity and the Fiedler vector of a generalized/weighted Laplacian matrix that depends on the stationary phase solutions of the system and is thereby inherently conditioned by the topology and the power distribution. Then, we aim to find out the isolated influence of topology on the perturbations when the network interacting agents have, in principle, opposite behaviors (i.e. producers and consumers). To do so, we study three networks: Small-world, Random, German grid. Furthermore, we tackle the effect of machine clustering on small perturbations and the influence of the network's average clustering coefficient on the intensity localization of the generalized Fiedler vector. Finally, we propose ways in which future (dynamic topology control) and existing (power system stabilizer) grid control strategies can adapt their response to comprehensively consider the topology and remote signals in the system.

description: In this study, the efficacy of membrane-photocatalytic reactor (MPR) in sulfamethoxazole (SMX) removal was explored at a fixed initial SMX concentration, i.e. 100 mg/L. A supported catalyst, i.e. TiO2 on granular activated carbon (GAC–TiO2), was used for MPR experiments. The SMX removal efficiency of the MPR was investigated under a range of hydraulic retention time (i.e. HRT from 51 to 152.5 min) and TiO2 catalyst dosage (55–50 mg/L). A maximum SMX removal efficiency of 83.6% was observed under 220 mg/L catalyst dosage and 80 min HRT. The increase in catalyst dosage from 55 to 550 mg/L has increased the transmembrane pressure of the reactor from 9.8 to 22.2 kPa. A multiple non-linear regression model was developed based on the experimental data and its significance was analyzed using two-way ANOVA. Based on the model, the optimal HRT and catalyst dosage for complete SMX removal (100%) were found out. The comparison of photocatalytic degradation experiments with sorption experiments conducted earlier revealed that SMX removal in the MPR was mainly by photocatalytic degradation and not by adsorption onto GAC–TiO2 catalyst. However, the performance of MPR in removing other emerging pollutants from real-time wastewaters could be explored before its field-scale application.

description: The prevalence of combinations of comorbidities and their associations with inpatient service utilization and readmission among patients with chronic obstructive pulmonary disease (COPD) have not been extensively examined. To address this gap in knowledge, an observational prospective study was conducted using retrospective data. To identify patterns of comorbidities linked to length of hospital stay, daily expenses, and one-year readmission. The 30 most common comorbidities were identified in patients with secondary diagnoses using the association rule mining (ARM) method. Regression models were used to examine the relationships between combinations of comorbidities and service utilization, with adjustments for covariates. The five most prevalent comorbidities were pulmonary heart disease (40.99%), ischemic heart disease (38.97%), heart failure (36.77%), hypertension (34.11%), and respiratory disorders (19.12%). Most combinations of comorbidities identified by ARM showed significant associations with an extended length of stay (>13 days), increased daily expenses (>930 CNY), and reduced readmission rates. Among these combinations, glycoprotein metabolism disorder had the strongest association with prolonged length of stay (adjusted odds ratio [aOR]): 1.89, 95% confidence interval [CI]: 1.82–1.95). Conversely, the combination of other brain diseases and respiratory failure was linked to higher daily expenses (aOR: 11.34, 95% CI: 10.58–12.15), and the presence of pulmonary heart disease was associated with elevated one-year readmission rates (aOR: 1.41, 95% CI: 1.37–1.46). Common combinations of comorbidities among inpatients with COPD were identified from an extensive collection of discharge medical records. Furthermore, the associations between comorbidities, inpatient service usage, and readmission rates were determined.

description: Van der Waals heterostructures (vdWHs) combine different layered materials with properties of interest,1 such as two-dimensional (2D) semimetals, semiconductors, magnets or superconductors. These heterostructures provide the possibility of engineering new materials with emergent functionalities that are not accessible in another way. Beyond inorganic 2D materials, layered molecular materials remain still rather unexplored, with only few examples regarding their isolation as atomically thin-layers. By a proper chemical design, the physical properties of these systems can be tuned, as illustrated by the so-called spin-crossover (SCO) compounds, in which a spin transition can be induced by applying external stimuli like light, temperature, pressure or an electric field. Here, we report on vdWHs formed by SCO layers and few-layers graphene, being its properties modified by the strain concomitant to the spin transition. These molecular/inorganic vdWHs represent the deterministic incorporation of bistable molecular layers with other 2D materials of interest in the emergent field of straintronics.

description: Unconstrained partial-wave amplitudes obtained at discrete energies from fits to complete sets of experimental data may not vary smoothly with energy, and are in principle non-unique. We demonstrate how this behavior can be ascribed to the continuum ambiguity. Starting from the spinless scattering case, we demonstrate how an unknown overall phase depending on energy and angle mixes the structures seen in the associated partial-wave amplitudes making the partial wave decomposition non-unique, and illustrate it on a simple toy model. We then apply these principles to pseudo-scalar meson photoproduction and show that the non-uniqueness effect can be removed through a phase rotation, allowing a consistent comparison with model amplitudes. The effect of this phase ambiguity is also considered for Legendre expansions of experimental observables. 5 pages,

description: The nuclear equation of state is an important component in the evolution of core collapse supernovae. In this paper we make a survey of various equations of state in the literature and analyze their effect on spherical core-collapse models in which the effects of three-dimensional turbulence is modeled by a general relativistic formulation of Supernova Turbulence in Reduced dimensionality (STIR). We show that the viability of the explosion is quite EOS dependent and that it best correlates with the early-time interior entropy density of the proto-neutron star. We check that this result is not progenitor dependent, although low-mass progenitors show different explosion properties, due to the different pre-collapse nuclear composition. Larger central entropies also induce more vigorous proto-neutron-star convection in our one-dimensional turbulence model, as well as a wider convective layer.

description: In this work we study the cosmological attractor models of inflation in connection with certain scalar-tensor theories of gravity, e.g $f(R)$ gravity and Brans-Dicke theory. For some particular choices of the functional degrees of freedom in these theories, one obtains Starobinsky like predictions in the ($n_s$-$r$) observable plane. We have demonstrated that these choices in the Lagrangian density of certain $f(R)$ and Brans-Dicke theories fulfil the condition of the cosmological attractors. That explains why known predictions of $f(R)$ and Brans-Dicke theories in certain cases appear to be the predictions of the much discussed attractor theories. In addition, we did an analysis showing how the predictions of an attractor model is preserved with respect to the variation in the functional freedom of the theory.

description: We investigate stellar elemental abundance patterns at z = 0 in 8 low-mass (M_* = 10^6 - 10^9 M_sun) galaxies in the Feedback in Realistic Environments (FIRE-2) cosmological simulations. Using magnesium (Mg) as a representative alpha-element, we explore stellar abundance patterns in [Mg/Fe] versus [Fe/H], which follow an overall monotonic trend that evolved slowly over time. Beyond this, we explore 3 notable secondary features in enrichment (found in three different case-study galaxies) that arise from a galaxy merger or bursty star formation. First, we observe a secondary track with a lower [Mg/Fe] than the main trend. At z = 0, stars from this track are predominantly found within 2-6 kpc of the center; they were accreted in a 1:3 total-mass-ratio merger ~ 0.4 Gyr ago. Second, we find a distinct elemental bi-modality that forms following a strong burst in star formation in a galaxy at t_lookback ~ 10 Gyr. This burst quenched star formation for ~ 0.66 Gyr, allowing Ia supernovae to enrich the system with iron before star formation resumed. Third, we examine stripes in enrichment that run roughly orthogonal to the dominant [Mg/Fe] versus [Fe/H] trend; these stripes correspond to short bursts of star formation during which core-collapse supernovae enrich the surrounding medium with Mg (and Fe) on short timescales. If observed, these features would substantiate the utility of elemental abundances in revealing the assembly and star formation histories of dwarf galaxies. We explore the observability of these features for upcoming spectroscopic studies. Our results show that precise measurements of elemental abundance patterns can reveal critical events in the formation histories of low-mass galaxies.

Generalized Dirac structure beyond the linear regime in graphene

description: We show that a generalized Dirac structure survives beyond the linear regime of the low-energy dispersion relations of graphene. A generalized uncertainty principle of the kind compatible with specific quantum gravity scenarios with a fundamental minimal length (here graphene lattice spacing) and Lorentz violation (here the particle/hole asymmetry, the trigonal warping, etc.) is naturally obtained. We then show that the corresponding emergent field theory is a table-top realization of such scenarios, by explicitly computing the third order Hamiltonian, and giving the general recipe for any order. Remarkably, our results imply that going beyond the low-energy approximation does not spoil the well-known correspondence with analogue massless quantum electrodynamics phenomena (as usually believed), but rather it is a way to obtain experimental signatures of quantum-gravity-like corrections to such phenomena.

Parafoveal degradation during reading reduces preview costs only when it is not perceptually distinct (VISDEG2 project)

description: There is a growing understanding that the parafoveal preview effect during reading may represent a combination of preview benefits and preview costs due to interference from parafoveal masks. It has been suggested that visually degrading the parafoveal masks may reduce their costs, but adult readers were later shown to be highly sensitive to degraded display changes. Four experiments examined how preview benefits and preview costs are influenced by the perception of distinct parafoveal degradation at the target word location. Participants read sentences with four preview types (identity, orthographic, phonological, and letter mask preview) and two levels of visual degradation (0 vs 20%). The distinctiveness of the target word degradation was either eliminated by degrading all words in the sentence (Experiments 1a-2a) or remained present, as in previous research (Experiments 1b-2b). Degrading the letter masks resulted in a reduction in preview costs, but only when all words in the sentence were degraded. When degradation at the target word location was perceptually distinct, it induced costs of its own, even for orthographically and phonologically related previews. These results confirm previous reports that traditional parafoveal masks introduce preview costs that overestimate the size of the true benefit. However, they also show that parafoveal degradation has the unintended consequence of introducing additional costs when participants are aware of distinct degradation on the target word. Parafoveal degradation appears to be easily perceived and may temporarily orient attention away from the reading task, thus delaying word processing.

description: Simulations of large-scale plasma systems are typically based on a fluid approximation approach. These models construct a moment-based system of equations that approximate the particle-based physics as a fluid, but as a result lack the small-scale physical processes available to fully kinetic models. Traditionally, empirical closure relations are used to close the moment-based system of equations, which typically approximate the pressure tensor or heat flux. The more accurate the closure relation, the stronger the simulation approaches kinetic-based results. In this paper, new closure terms are constructed using machine learning techniques. Two different machine learning models, a multi-layer perceptron and a gradient boosting regressor, synthesize a local closure relation for the pressure tensor and heat flux vector from fully kinetic simulations of a 2D magnetic reconnection problem. The models are compared to an existing closure relation for the pressure tensor, and the applicability of the models is discussed. The initial results show that the models can capture the diagonal components of the pressure tensor accurately, and show promising results for the heat flux, opening the way for new experiments in multi-scale modeling. We find that the sampling of the points used to train both models play a capital role in their accuracy.

description: We revisit the classical problem of the planar Euler \emph{elastica} with applied forces and moments, and present a classification of the shapes in terms of tangentially conserved quantities associated with spatial and material symmetries. We compare commonly used director, variational, and dynamical systems representations, and present several illustrative physical examples. We remark that an approach that employs only the shape equation for the tangential angle obscures physical information about the tension in the body.

description: Die Möglichkeiten, die Papst Franziskus eröffnet hat, Laien kirchliche Leitungsgewalt zu übertragen, sind beachtlich. Bei Ehenichtigkeitsverfahren können zwei der drei Richter eines Richterkollegiums Laien sein. Leitungsämter an der Römischen Kurie, das Amt des Präfekten eines Dikasteriums grundsätzlich nicht ausgenommen, können mit Laien besetzt werden. In klerikalen Religioseninstituten können mit Genehmigung des Dikasteriums für die Institute des geweihten Lebens und die Gesellschaften des apostolischen Lebens auch Laien Oberenämter bekleiden. Dabei ist Papst Franziskus den Weg der Praxis gegangen, d. h. er hat die kirchenrechtlichen Bestimmungen angepasst, ohne die Änderungen jedoch theologisch zu untermauern. Ausübung von Leitungsgewalt in der Kirche ist etwas qualitativ anderes als Ausübung von Leitungsgewalt im Staat. Was noch aussteht, ist eine tiefergehende theologische Reflexion der Thematik, um die Möglichkeit der Übertragung von kirchlicher Leitungsgewalt an Laien auf ein sicheres Fundament zu stellen und möglicherweise noch auszuweiten.
