description: Gravitational waves (GW) generated during a core-collapse supernova open a window into the heart of the explosion. At core bounce, progenitors with rapid core rotation rates exhibit a characteristic GW signal which can be used to constrain the properties of the core of the progenitor star. We investigate the dynamics of rapidly rotating core collapse, focusing on hydrodynamic waves generated by the core bounce and the GW spectrum they produce. The centrifugal distortion of the rapidly rotating proto-neutron star (PNS) leads to the generation of axisymmetric quadrupolar oscillations within the PNS and surrounding envelope. Using linear perturbation theory, we estimate the frequencies, amplitudes, damping times, and GW spectra of the oscillations. Our analysis provides a qualitative explanation for several features of the GW spectrum and shows reasonable agreement with nonlinear hydrodynamic simulations, although a few discrepancies due to non-linear/rotational effects are evident. The dominant early postbounce GW signal is produced by the fundamental quadrupolar oscillation mode of the PNS, at a frequency $0.70 \, {\rm kHz} \lesssim f \lesssim 0.80\,{\rm kHz}$, whose energy is largely trapped within the PNS and leaks out on a $\sim\!10$ ms timescale. Quasi-radial oscillations are not trapped within the PNS and quickly propagate outwards until they steepen into shocks. Both the PNS structure and Coriolis/centrifugal forces have a strong impact on the GW spectrum, and a detection of the GW signal can therefore be used to constrain progenitor properties.

Theory of polar domains in moiré heterostructures

description: The discovery of unconventional ferroelectric behavior in twisted bilayers has prompted the consideration of moiré heterostructures as polar materials. However, misconceptions about the nature and origin of the observed ferroelectricity indicate that a better theoretical understanding of the polar properties of moiré heterostructures is needed. In this paper, it is proposed, and verified with first-principles calculations, that all moiré heterostructures exhibit an out-of-plane moiré polar domain (MPD) structure. In transition metal dichalcogenide bilayers, an interlayer charge transfer occurs due to the change in stacking arrangements throughout the moiré superlattice, leading to a local out-of-plane dipole moment, with the magnitude and shape of the MPDs being dominated by the chalcogen atoms. While the MPDs in all heterostructures are sensitive to the moiré period, it is only in the homo-bilayers that they can be tuned with an out-of-plane electric field. The misconceptions about ferroelectricity in moiré heterostructures are addressed, and it is proposed that the only scenario in which the MPDs can be considered ferroelectric domains is via a global van der Waals sliding by one third of a unit cell in a homo-bilayer. Finally, a general theoretical discussion of the polar properties of moiré heterostructures is provided.

description: Many self-propelled microorganisms are attracted to surfaces. This makes their dynamics in restricted geometries very different from that observed in the bulk. Swimming along walls is beneficial for directing and sorting cells, but may be detrimental if homogeneous populations are desired, such as in counting microchambers. In this work, we characterize the motion of human sperm cells $60 μm$ long, strongly confined to $25 μm$ shallow chambers. We investigate the nature of the cell trajectories between the confining surfaces and their accumulation near the borders. Observed cell trajectories are composed of a succession of quasi-circular and quasi-linear segments. This suggests that the cells follow a path of intermittent trappings near the top and bottom surfaces separated by stretches of quasi-free motion in between the two surfaces, as confirmed by depth resolved confocal microscopy studies. We show that the introduction of artificial petal-shaped corrugation in the lateral boundaries removes the tendency of cells to accumulate near the borders, an effect which we hypothesize may be valuable for microfluidic applications in biomedicine.

Dynamics of forced and unforced autophoretic particles

description: Chemically active, or autophoretic, particles that isotropically emit or absorb solute molecules undergo spontaneous self-propulsion when their activity is increased beyond a critical Péclet number ($Pe$). Here, we conduct numerical computations, using a spectral-element based method, of a rigid, spherical autophoretic particle in unsteady rectilinear translation. The particle can be freely suspended (or `unforced') or subject to an external force field (or `forced'). The motion of an unforced particle progresses through four regimes as $Pe$ is increased: quiescent, steady, stirring, and chaos. The particle is stationary in the quiescent regime, and the solute profile is isotropic about the particle. At $Pe=4$ the fore-aft symmetry in the solute profile is broken, resulting in its steady self-propulsion. Our computations indicate that the self-propulsion speed scales linearly with $Pe-4$ near the onset of self-propulsion, as has been predicted in previous studies. A further increase in $Pe$ gives rise to the stirring regime at $Pe\approx27$, where the fluid undergoes recirculation, while the particle remains essentially stationary. As $Pe$ is increased even further, the particle dynamics are marked by chaotic oscillations at $Pe\approx55$ and higher, which we characterize in terms of the mean square displacement and velocity autocorrelation of the particle. Our results for an autophoretic particle under a weak external force are in good agreement with recent asymptotic predictions (Saha, Yariv, and Schnitzer, J. Fluid Mech., vol. 916, A47, 2021). Additionally, we demonstrate that the strength and temporal scheduling of the external force may be tuned to modulate the chaotic dynamics at large $Pe$.

description: Systematic development of accurate density functionals has been a decades-long challenge for scientists. Despite the emerging application of machine learning (ML) in approximating functionals, the resulting ML functionals usually contain more than tens of thousands parameters, which makes a huge gap in the formulation with the conventional human-designed symbolic functionals. We propose a new framework, Symbolic Functional Evolutionary Search (SyFES), that automatically constructs accurate functionals in the symbolic form, which is more explainable to humans, cheaper to evaluate, and easier to integrate to existing density functional theory codes than other ML functionals. We first show that without prior knowledge, SyFES reconstructed a known functional from scratch. We then demonstrate that evolving from an existing functional $ω$B97M-V, SyFES found a new functional, GAS22 (Google Accelerated Science 22), that performs better for the majority of molecular types in the test set of Main Group Chemistry Database (MGCDB84). Our framework opens a new direction in leveraging computing power for the systematic development of symbolic density functionals.

description: We study the effect of PT-symmetric complex potentials on the transport properties of non-Hermitian systems, which consist of an infinite linear chain and two side-coupled defect points with PT-symmetric complex on-site potentials. By analytically solving the scattering problem of two typical models, which display standard Fano resonances in the absence of non-Hermitian terms, we find that the PT-symmetric imaginary potentials can lead to some pronounced effects on transport properties of our systems, including changes from the perfect reflection to perfect transmission, and rich behaviors for the absence or existence of the prefect reflection at one and two resonant frequencies. Our study can help us to understand the interplay between the Fano resonance and PT symmetry in non-Hermitian discrete systems, which may be realizable in optical waveguide experiments.

description: In this proceeding, we review modified theories of gravity with a curvature-matter coupling between an arbitrary function of the scalar curvature and the Lagrangian density of matter. This explicit nonminimal coupling induces a non-vanishing covariant derivative of the energy-momentum tensor, that implies non-geodesic motion and consequently leads to the appearance of an extra force. Here, we explore the physical and cosmological implications of the nonconservation of the energy-momentum tensor by using the formalism of irreversible thermodynamics of open systems in the presence of matter creation/annihilation. The particle creation rates, pressure, and the expression of the comoving entropy are obtained in a covariant formulation and discussed in detail. Applied together with the gravitational field equations, the thermodynamics of open systems lead to a generalization of the standard $Λ$CDM cosmological paradigm, in which the particle creation rates and pressures are effectively considered as components of the cosmological fluid energy-momentum tensor. Furthermore, we also briefly present the coupling of curvature to geometry in conformal quadratic Weyl gravity, by assuming a coupling term of the form $L_m\tilde{R}^2$, where $L_m$ is the ordinary matter Lagrangian, and $\tilde{R}$ is the Weyl scalar. The coupling explicitly satisfies the requirement of the conformal invariance of the theory. Expressing $\tilde{R}^2$ with the use of an auxiliary scalar field and of the Weyl scalar, the gravitational action can be linearized in the Ricci scalar, leading in the Riemann space to a conformally invariant $f\left(R,L_m\right)$ type theory, with the matter Lagrangian nonminimally coupled to geometry.

description: Cuspidal robots are robots with at least two inverse kinematic solutions that can be connected by a singularity-free path. Deciding the cuspidality of generic 3R robots has been studied in the past, but extending the study to six-degree-of-freedom robots can be a challenging problem. Many robots can be modeled as a polynomial map together with a real algebraic set so that the notion of cuspidality can be extended to these data. In this paper we design an algorithm that, on input a polynomial map in $n$ indeterminates, and $s$ polynomials in the same indeterminates describing a real algebraic set of dimension $d$, decides the cuspidality of the restriction of the map to the real algebraic set under consideration. Moreover, if $D$ and $τ$ are, respectively the maximum degree and the bound on the bit size of the coefficients of the input polynomials, this algorithm runs in time log-linear in $τ$ and polynomial in $((s+d)D)^{O(n^2)}$. It relies on many high-level algorithms in computer algebra which use advanced methods on real algebraic sets and critical loci of polynomial maps. As far as we know, this is the first algorithm that tackles the cuspidality problem from a general point of view.

description: Andreev reflection of thermal quasiparticles from quantized vortices is an important technique to visualize quantum turbulence in low temperature $^3$He-$B$. We revisit a problem of Andreev reflection from the isolated, rectilinear vortex line. For quasiparticle excitations whose impact parameters, defined as distances of the closest approach to the vortex core, do not exceed some arbitrary value, $b$, we calculate exactly the reflected fraction of the total flux of excitations incident upon the vortex in the direction orthogonal to the vortex line. We then define and calculate exactly, as a function of $b$, the scattering length, that is the scattering cross-section per unit length of the vortex line. We also define and calculate the scattering lengths for the flux of energy carried by thermal excitations, and for the net energy flux resulting from a (small) temperature gradient, and analyze the dependence of these scattering lengths on temperature.

description: In quantum state discrimination, one aims to identify unknown states from a given ensemble by performing measurements. Different strategies such as minimum-error discrimination or unambiguous state identification find different optimal measurements. Maximum-confidence measurements (MCMs) maximise the confidence with which inputs can be identified given the measurement outcomes. This unifies a range of discrimination strategies including minimum-error and unambiguous state identification, which can be understood as limiting cases of MCM. In this work, we investigate MCMs for general ensembles of qubit states. We present a method for finding MCMs for qubit-state ensembles by exploiting their geometry and apply it to several interesting cases, including ensembles two and four mixed states and ensembles of an arbitrary number of pure states. We also compare MCMs to minimum-error and unambiguous discrimination for qubits. Our results provide interpretations of various qubit measurements in terms of MCM and can be used to devise qubit protocols.

title: Analyzing the Positive Sentiment Towards the Term “Queer’’ in Virginia Woolf through a Computational Approach and Close Reading
Creators: name: Shin, Heejoung
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: This article validates the thesis that Virginia Woolf’s usage of the term “queer’’ is positive, and that the author is more progressive with her idea of things conceived as “queer’’ in the era characterized as literary Modernism and in English fiction as a whole from 1850s to 1990s. Using Word2Vec, a word embedding model, I locate the top 100 words semantically closest to “queer’’ in Woolf’s works and in the works of other modernist authors, James Joyce, F. Scott Fitzgerald, D. H. Lawrence, Gertrude Stein, and Katherine Mansfield. I then measure the net positivity of each author’s list and compare Woolf’s with the individual authors’, and then with words closest to “queer’’ in English fiction from 1850 to 2000. In demonstrating the usefulness of applying word embedding models in literary criticism, a field that has traditionally primarily relied on interpretation, this article aims to serve as a case study of how a computational approach can benefit close reading.

Un convegno che ha reso possibile un incontro, a distanza di anni, tra gli allievi dottorandi che hanno condiviso gli insegnamenti di uno dei più prestigiosi pedagogisti italiani del ‘900, Aldo Visalberghi. Un convegno per riprendere quel dialogo formativo, quel confronto tra gli allievi dei primi cicli di dottorato e alcuni colleghi del collegio di dottorato coordinato di fatto da Visalberghi dal 1984 e fino al 2002. Un dottorato unico nel panorama formativo dei cicli dottorali, in quanto di natura consortile, connotato da una forte impronta interdisciplinare e una particolare attenzione alle dimensioni teoriche intersettoriali e a modelli metodologici misti. Gli interventi vari hanno permesso di ripercorrere le idee fondative e le prospettive pedagogiche di quel percorso formativo, e di formulare e riflettere sulla centralità del discorso pedagogico, oggi, nella formazione alla ricerca e alla sperimentazione in campo educativo.

description: We present an algorithm for solving the radiative transfer problem on massively parallel computers using adaptive mesh refinement and domain decomposition. The solver is based on the method of characteristics which requires an adaptive raytracer that integrates the equation of radiative transfer. The radiation field is split into local and global components which are handled separately to overcome the non-locality problem. The solver is implemented in the framework of the magneto-hydrodynamics code FLASH and is coupled by an operator splitting step. The goal is the study of radiation in the context of star formation simulations with a focus on early disc formation and evolution. This requires a proper treatment of radiation physics that covers both the optically thin as well as the optically thick regimes and the transition region in particular. We successfully show the accuracy and feasibility of our method in a series of standard radiative transfer problems and two 3D collapse simulations resembling the early stages of protostar and disc formation.

description: The Bistritzer-MacDonald continuum model (BM model) describes the low-energy moiré bands for twisted bilayer graphene (TBG) at small twist angles. We derive a generalized continuum model for TBG near any commensurate twist angle, which is characterized by complex interlayer hoppings at commensurate $AA$ stackings (rather than the real hoppings in the BM model), a real interlayer hopping at commensurate $AB/BA$ stackings, and a global energy shift. The complex phases of the $AA$ stacking hoppings and the twist angle together define a single angle parameter $ϕ_0$. We compute the model parameters for the first six distinct commensurate TBG configurations, among which the $38.2^\circ$ configuration may be within experimentally observable energy scales. We identify the first magic angle for any $ϕ_0$ at a condition similar to that of the BM model. At this angle, the lowest two moiré bands at charge neutrality become flat except near the $\boldsymbolΓ_M$ point and retain fragile topology but lose particle-hole symmetry. We further identify a hypermagic parameter regime centered at $ϕ_0 = \pmπ/2$ where many moiré bands around charge neutrality (often $8$ or more) become flat simultaneously. Many of these flat bands resemble those in the kagome lattice and $p_x$, $p_y$ 2-orbital honeycomb lattice tight-binding models.

description: La consulenza filosofica ha le sue radici nella crisi della razionalità teoretica e nella riabilitazione della filosofia pratica. Essa nasce dall'incontro di due percorsi, i risultati teoretici del decostruzionismo dell'ultimo secolo e la contingenza storica con gli effetti della globalizzazione. È la rovina dell'Io nelle società tecnologicamente avanzate che riporta in auge le antiche tradizioni delle pratiche filosofiche, che ai margini della ricerca epistemologica, hanno avuto sempre un posto nella tradizione filosofica dell'Occidente. Guardando all'incostanza e all'inconsistenza della coscienza individuale, l'incapacità di raggiungere il Sé nelle giovani generazioni, che si abbandonano ad emozioni transitorie, il consulente filosofico ascolta il disagio che è sempre un segno della ricerca di sé e apre inoltre alla possibilità di pensare insieme al cliente il nostro tempo.

description: Lo scopo è di presentare la consulenza filosofica come una "nuova" disciplina che abbia il compito di ridirezionare l'etica, e soprattutto di mostrare come il progetto di confrontare la ricerca filosofica e la consulenza filosofica possa essere un arricchimento per entrambe, e possa aiutare a combattere stanchi stereotipi, trovando invece collegamenti significativi. In secondo luogo, si cerca un possibile confronto tra la consulenza filosofica e la diversità sessuale, o il pensiero femminista. Si argomenta che tale pensiero si caratterizza principalmente come pensiero esperienziale e soprattutto come pratica filosofica, e si dimostra che il pensiero femminista è, per via delle sue origini e per il contesto in cui nacque, uno dei più significativi esempi del collegamento tra pratica filosofica e prassi (uno specifico tipo di prassi).

La commistione tra il pensiero femminista e la consulenza filosofica può essere una forza direttrice per entrambe, e per altre discipline come la letteratura, il teatro, il cinema o la religione; può inoltre portare in primo piano altre aree di studio come l'autobiografia, l'epistolario e la biografia; oppure, infine, può spostare l'attenzione su certi autori (la riscoperta delle scrittrici femminili è fondamentale per il femminismo) e su problemi specifici e su questioni che sono inusuali per la grande tradizione filosofica.

description: The Data Stewardship Wizard (DSW) has become a distinguished ELIXIR tool for creating smart data management plans. Its development is strongly user-feedback driven, which allows the DSW to stay up-to-date with users’ needs and their expectations. The whole DSW team supports and works closely with individual users as well with organizations on their maximum quality in use and any type of feedback is very welcome and important for improving the DSW. This close engagement with the DSW community lately resulted in several improvements and development of new features. Live Collaboration is one of them - it gives users the opportunity to be working on the data management plan (DMP) in their teams together in real time. Easy sharing of a DMP or interoperability with other tools are another examples of the newly introduced features. We expect that a recent Advisory Board meeting, upcoming BioHackathon Europe and other DSW activities will bring more ideas for possible improvements and new features in near future.

description: We investigate topological properties of density matrices motivated by the question to what extent phenomena like topological insulators and superconductors can be generalized to mixed states in the framework of open quantum systems. The notion of geometric phases has been extended from pure to mixed states by Uhlmann in [Rep. Math. Phys. 24, 229 (1986)], where an emergent gauge theory over the density matrices based on their pure-state representation in a larger Hilbert space has been reported. However, since the uniquely defined square root $\sqrtρ$ of a density matrix $ρ$ provides a global gauge, this construction is always topologically trivial. Here, we study a more restrictive gauge structure which can be topologically non-trivial and is capable of resolving homotopically distinct mappings of density matrices subject to various spectral constraints. Remarkably, in this framework, topological invariants can be directly defined and calculated for mixed states. In the limit of pure states, the well known system of topological invariants for gapped band structures at zero temperature is reproduced. We compare our construction with recent approaches to Chern insulators at finite temperature.

For all dimensions $d\ne 2$, universal characteristics distinguish the Arcetri model from the Edwards-Wilkinson model, although for $d>2$ all stationary and non-equilibrium exponents are the same. For $d=1$ dimensions, the Arcetri model is equivalent to the $p=2$ spherical spin glass. For $2

description: La proposta di dedicare un tema della nostra rivista alla consulenza filosofica vuole essere anzitutto un'occasione per "raccogliere" le indicazioni, provenienti dalla ricerca filosofica attuale, di un interesse che non si esaurisce solo nella riabilitazione della filosofia pratica, nel riflettere intorno alla vita pratica dell'uomo, ma che mira anche alla riattivazione di pratiche filosofiche nella vita quotidiana.

description: Cominciando con il principio, teorizzato da Jung, che le malattie dell'anima sorgano da un corso irregolare della scoperta di sé, e dopo aver descritto nel § 1 il caratteristico profilo di quest'ultima, nel § 2 chiariremo le vie per cui, stando a Jung, dovrebbe essere condotta la pratica terapeutica. E dato che l'anima è caratterizzata dal suo essere antinomica, l'approccio della psicologia analitica alla cura deve essere strutturato dialetticamente.

description: While the squeezing of a propagating field can, in principle, be made arbitrarily strong, the cavity-field squeezing is subject to the well-known 3 dB limit, and thus has limited applications. Here, we propose the use of a fully quantum degenerate parametric amplifier (DPA) to beat this squeezing limit. Specifically, we show that by {\it simply} applying a two-tone driving to the signal mode, the pump mode can, {\it counterintuitively}, be driven by the photon loss of the signal mode into a squeezed steady state with, in principle, an {\it arbitrarily high} degree of squeezing. Furthermore, we demonstrate that this intracavity squeezing can increase the signal-to-noise ratio of longitudinal qubit readout {\it exponentially} with the degree of squeezing. Correspondingly, an improvement of the measurement error by {\it many orders of magnitude} can be achieved even for modest parameters. In stark contrast, using intracavity squeezing of the semiclassical DPA {\it cannot} practically increase the signal-to-noise ratio and thus improve the measurement error. Our results extend the range of applications of DPAs and open up new opportunities for modern quantum technologies.

description: The analysis of x-ray reflectivity data from artificial heterostructures usually relies on the homogeneity of optical properties of the constituent materials. However, when the x-ray energy is tuned to an absorption edge, this homogeneity no longer exists. Within the same material, spatial regions containing elements at resonance will have optical properties very different from regions without resonating sites. In this situation, models assuming homogeneous optical properties throughout the material can fail to describe the reflectivity adequately. As we show here, resonant soft x-ray reflectivity is sensitive to these variations, even though the wavelength is typically large as compared to the atomic distances over which the optical properties vary. We have therefore developed a scheme for analyzing resonant soft x-ray reflectivity data, which takes the atomic structure of a material into account by "slicing" it into atomic planes with characteristic optical properties. Using LaSrMnO4 as an example, we discuss both the theoretical and experimental implications of this approach. Our analysis not only allows to determine important structural information such as interface terminations and stacking of atomic layers, but also enables to extract depth-resolved spectroscopic information with atomic resolution, thus enhancing the capability of the technique to study emergent phenomena at surfaces and interfaces.

description: List of spacer sequences newly acquired upon infection with SIRV2M (column 1) and their PAM sequence (column 2). The CRISPR-Cas subtypes capable of utilizing each new spacer is specified (column 3) along with the location of the spacer in the SIRV2 genome (column 4). Spacer complementarity to sense strand (column 1) is especially important for the transcription dependent targeting of subtype III-B CRISPR-Cas systems.
LPV sequential loop closing for high-precision motion systems

description: Increasingly stringent throughput requirements in the industry necessitate the need for lightweight design of high-precision motion systems to allow for high accelerations, while still achieving accurate positioning of the moving-body. The presence of position dependent dynamics in such motion systems severely limits achievable position tracking performance using conventional sequential loop closing (SLC) control design strategies. This paper presents a novel extension of the conventional SLC design framework towards linear-parameter-varying systems, which allows to circumvent limitations that are introduced by position dependent effects in high-precision motion systems. Advantages of the proposed control design approach are demonstrated in simulation using a high-fidelity model of a moving-magnet planar actuator system, which exhibits position dependency in both actuation and sensing.

title: “Otium et negotium”. Seneca e la “scelta di sé”
Creators: name: Di Marco , Chiara
Publisher: name: Roma Tre-Press
Year: 2013

description: Accordo, coerenza, fermezza. La filosofia non consiste in parole ma in azioni; insegna come agire, non come parlare, e richiede che ognuno viva in accordo con le proprie norme, così che le parole siano suoni vuoti e la vita sia coerente con se stessa. La filosofia è allora logos che diventa bios: pensiero che modella uno stile di vita – un'etica, stando a Foucault, che diviene un'estetica dell'esistenza –; questo è l'organon/pharmakon che combina logos e erga, dove la "e" indica in ogni caso una congiunzione disgiuntiva, un cum, potremmo dire, che mentre rispetta le competenze delle singole facoltà, converte il potere teoretico della riflessione nel buon senso della seggezza pratica. La "cura di sé", come esercizio che intende acquisire una sovranità sullo stile di vita, indica l'apertura/attenzione all'umanità intera che è il centro della riflessione stoica, un universale che, paradossalmente, Seneca trova nella solitudine del ritiro, quando sostituisce il fallimento dell'incarico politico con la forza educativa della scrittura, come un'arma che è capace di perforare l'egoismo e quegli interessi che sono un insulto alla vita.

Spectral signatures of thermal spin disorder and excess Mn in half-metallic NiMnSb

description: Effects of thermal spin disorder and excess Mn on the electronic spectrum of half-metallic NiMnSb are studied using first-principles calculations. Temperature-dependent spin disorder, introduced within the vector disordered local moment model, causes the valence band at the $Γ$ point to broaden and shift upwards, crossing the Fermi level and thereby closing the half-metallic gap above room temperature. The spectroscopic signatures of excess Mn on the Ni, Sb, and empty sites (Mn$_\mathrm{Ni}$, Mn$_\mathrm{Sb}$, and Mn$_\mathrm{E}$) are analyzed. Mn$_\mathrm{Ni}$ is spectroscopically invisible. The relatively weak coupling of Mn$_\mathrm{Sb}$ and Mn$_\mathrm{E}$ spins to the host strongly deviates from the Heisenberg model, and the spin of Mn$_\mathrm{E}$ is canted in the ground state. While the half-metallic gap is preserved in the collinear ground state of Mn$_\mathrm{Sb}$, thermal spin disorder of the weakly coupled Mn$_\mathrm{Sb}$ spins destroys it at low temperatures. This property of Mn$_\mathrm{Sb}$ may be the source of the observed low-temperature transport anomalies.

description: Il saggio medita su come la consulenza filosofica cerchi di contrastare l'elusione di questioni filosofiche nel nostro tormentato mondo contemporaneo. Dopo che gran parte del pensiero del ventesimo secolo ha decostruito molte delle risposte lasciate dalla modernità, i problemi del significato e del soggetto continuano a ritornare, e la filosofia pratica, o piuttosto alcune forme di filosofia pratica, affrontano questi problemi nel tentativo di creare una sfera indipendente. Una sfera che si pone tra l'esito nichilista della "cultura del narcisismo" e alcuni esiti estremi della "sensibilità terapeutica", in competizione con alcuni risultati della psicoanalisi, ma tenendo lo specifico approccio critico che è innato alla filosofia.

description: We develop relative oscillation theory for general Sturm-Liouville differential expressions of the form \[ \frac{1}{r}\left(-\frac{\mathrm d}{\mathrm dx} p \frac{\mathrm d}{\mathrm dx} + q\right) \] and prove perturbation results and invariance of essential spectra in terms of the real coefficients $p$, $q$, $r$. The novelty here is that we also allow perturbations of the weight function $r$ in which case the unperturbed and the perturbed operator act in different Hilbert spaces.

description: Meta-learning is a branch of machine learning which trains neural network models to synthesize a wide variety of data in order to rapidly solve new problems. In process control, many systems have similar and well-understood dynamics, which suggests it is feasible to create a generalizable controller through meta-learning. In this work, we formulate a meta reinforcement learning (meta-RL) control strategy that can be used to tune proportional--integral controllers. Our meta-RL agent has a recurrent structure that accumulates "context" to learn a system's dynamics through a hidden state variable in closed-loop. This architecture enables the agent to automatically adapt to changes in the process dynamics. In tests reported here, the meta-RL agent was trained entirely offline on first order plus time delay systems, and produced excellent results on novel systems drawn from the same distribution of process dynamics used for training. A key design element is the ability to leverage model-based information offline during training in simulated environments while maintaining a model-free policy structure for interacting with novel processes where there is uncertainty regarding the true process dynamics. Meta-learning is a promising approach for constructing sample-efficient intelligent controllers.
