description: Near-infrared spectroscopy from APOGEE and wide-field optical photometry from Pan-STARRS1 have recently made possible precise measurements of the shape of the extinction curve for tens of thousands of stars, parameterized by R(V). These measurements revealed structures in R(V) with large angular scales, which are challenging to explain in existing dust paradigms. In this work, we combine three-dimensional maps of dust column density with R(V) measurements to constrain the three-dimensional distribution of R(V) in the Milky Way. We find that variations in R(V) are correlated on kiloparsec scales. In particular, most of the dust within one kiloparsec in the outer Galaxy, including many local molecular clouds (Orion, Taurus, Perseus, California, Cepheus), has a significantly lower R(V) than more distant dust in the Milky Way. These results provide new input to models of dust evolution and processing, and complicate application of locally derived extinction curves to more distant regions of the Milky Way and to other galaxies.

description: We present a visually grounded model of speech perception which projects spoken utterances and images to a joint semantic space. We use a multi-layer recurrent highway network to model the temporal nature of spoken speech, and show that it learns to extract both form and meaning-based linguistic knowledge from the input signal. We carry out an in-depth analysis of the representations used by different components of the trained model and show that encoding of semantic aspects tends to become richer as we go up the hierarchy of layers, whereas encoding of form-related aspects of the language input tends to initially increase and then plateau or decrease.

description: Video meeting platforms display conversations linearly through transcripts or summaries. However, ideas during a meeting do not emerge linearly. We leverage LLMs to create dialogue maps in real time to help people visually structure and connect ideas. Balancing the need to reduce the cognitive load on users during the conversation while giving them sufficient control when using AI, we explore two system variants that encompass different levels of AI assistance. In Human-Map, AI generates summaries of conversations as nodes, and users create dialogue maps with the nodes. In AI-Map, AI produces dialogue maps where users can make edits. We ran a within-subject experiment with ten pairs of users, comparing the two MeetMap variants and a baseline. Users preferred MeetMap over traditional methods for taking notes, which aligned better with their mental models of conversations. Users liked the ease of use for AI-Map due to the low effort demands and appreciated the hands-on opportunity in Human-Map for sense-making.

description: Superconducting circuit technologies have recently achieved quantum protocols involving closed feedback loops. Quantum artificial intelligence and quantum machine learning are emerging fields inside quantum technologies which may enable quantum devices to acquire information from the outer world and improve themselves via a learning process. Here we propose the implementation of basic protocols in quantum reinforcement learning, with superconducting circuits employing feedback-loop control. We introduce diverse scenarios for proof-of-principle experiments with state-of-the-art superconducting circuit technologies and analyze their feasibility in presence of imperfections. The field of quantum artificial intelligence implemented with superconducting circuits paves the way for enhanced quantum control and quantum computation protocols.

description: Let $v_1$, $v_2$, ..., $v_n$ be real numbers whose squares add up to 1. Consider the $2^n$ signed sums of the form $S = \sum \pm v_i$. Holzman and Kleitman (1992) proved that at least 3/8 of these sums satisfy $|S| \le 1$. This 3/8 bound seems to be the best their method can achieve. Using a different method, we improve the bound to 13/32, thus breaking the 3/8 barrier.
description: Version 3 improves the lower bound from 13/32 = 0.40625 to 0.406259. This version is the same as the journal version, except for formatting. 10 pages

description: We discuss the existence of positive superharmonic functions $u$ in $\mathbb{R}^N_+=\mathbb{R}^{N-1}\times (0, \infty)$, $N\geq 3$, in the sense $-Δu=μ$ for some Radon measure $μ$, so that $u$ satisfies the nonlocal boundary condition $$ \frac{\partial u}{\partial n}(x',0)=λ\int\limits_{\mathbb{R}^{N-1}}\frac{u(y',0)^p}{|x'-y'|^k}dy' \quad\mbox{ on }\partial \mathbb{R}^N_+, $$ where $p,λ>0$ and $k\in (0, N-1)$. First, we show that no solutions exist if $0p^*$ and discuss the existence of regular solutions, case in which we identify a second critical exponent given by $p^{**}=2\cdot \frac{N-1}{k-1}-1$. Our approach combines various integral estimates with the properties of the newly introduced $α$-lifting operator and fixed point theorems.
One-dimensional electron gas in strained lateral heterostructures of single layer materials

description: Confinement of the electron gas along one of the spatial directions opens an avenue for studying fundamentals of quantum transport along the side of numerous practical electronic applications, with high-electron-mobility transistors being a prominent example. A heterojunction of two materials with dissimilar electronic polarisation can be used for engineering of the conducting channel. Extension of this concept to single-layer materials leads to one-dimensional electron gas (1DEG). MoS2/WS2 lateral heterostructure is used as a prototype for the realisation of 1DEG. The electronic polarisation discontinuity is achieved by straining the heterojunction taking advantage of dissimilarities in the piezoelectric coupling between MoS2 and WS2. A complete theory that describes an induced electric field profile in lateral heterojunctions of two-dimensional materials is proposed and verified by first principle calculations.

description: Statt der Forschung ethische, rechtliche, gesellschaftliche Reflexion nur beizugesellen, verlangt Responsible Research and Innovation (RRI), dass sich Forschung an europäischen Werten – den Werten der Europäischen Union – orientiert. Um diese Öffnung zu gewährleisten, setzt RRI zunächst nicht auf spezifische Werte, sondern prozedural auf eine Forschung, die Folgen antizipiert, unterschiedliche Interessen und Wertvorstellungen inkludiert, sich selbst reflektiert und in die Verantwortung nehmen lässt. Doch was heißt das? In Zusammenarbeit mit IANUS (Science, Technology, Peace) veranstaltete die Darmstädter Schader-Stiftung am 19. April 2018 einen interdisziplinären Workshop und ein Forum Offene Wissenschaft unter dem Titel »Science and Engineering for Global Peace – A Makerspace for Responsible Innovation« (Wissenschaft und Technik für Frieden und Sicherheit), um sich unter der Fragestellung »Ein europäisches In­stru­ment zur Förderung der naturwissenschaftlich-technischen Friedensforschung?« näher mit RRI zu beschäftigen. An dem eintägigen Workshop nahmen 32 Teilnehmer*innen aus zwölf Disziplinen (Arbeitswissenschaften, Architektur, Biologie, Gesellschaftswissenschaften, Informatik, Materialwissenschaften, Philosophie, Physik, Politikwissenschaft, Sportwissenschaften, Technikfolgenabschätzung, Techniksoziologie) teil.

description: A first-order differential equation is provided for a one-form, spin-s connection valued in the two-row, width-(s-1) Young tableau of GL(5). The connection is glued to a zero-form identified with the spin-s Cotton tensor. The usual zero-Cotton equation for a symmetric, conformal spin-s tensor gauge field in 3D is the flatness condition for the sum of the GL(5) spin-s and background connections. This presentation of the equations allows to reformulate in a compact way the cohomological problem studied in 1511.07389, featuring the spin-s Schouten tensor. We provide full computational details for spin 3 and 4 and present the general spin-s case in a compact way.

description: Holographic models provide unique laboratories to investigate non-linear physics of transport in inhomogeneous systems. We provide a detailed account of both DC and AC conductivities in a defect CFT with spontaneous stripe order. The spatial symmetry is broken at large chemical potential and the resulting ground state is a combination of a spin and charge density wave. An infinitesimal applied electric field across the stripes will cause the stripes to slide over the underlying density of smeared impurities, a phenomenon which can be associated with the Goldstone mode for the spontaneously broken translation symmetry. We show that the presence of a spatially modulated background magnetization current thwarts the expression of some DC conductivities in terms of horizon data.

Phase transitions and spin excitations of spin-1 bosons in optical lattice

description: We investigate ground state properties of spin-1 bosonic system trapped in optical lattice with extended standard basis operator (SBO) method. For both ferromagnetic ($U_2<0$) and antiferromagnetic ($U_2>0$) systems, we analytically figure out the symmetry properties in Mott-insulator and superfluid phases, which would provide a deeper insight into the MI-SF phase transition process. Then by applying self-consistent approach to the method, we include the effect of quantum and thermal fluctuations and derive the MI-SF transition phase diagram, which is in quantitative agreement with recent Monte-Carlo simulation at zero temperature, and at finite temperature, we find the underestimation of finite-temperature-effect in the mean-field approximation method. If we further consider the spin excitations in the insulating states of spin-1 system in external field, distinct spin phases are expected. Therefore, in the Mott lobes with $n=1$ and $n=2$ atoms per site, we give analytical and numerical boundaries of the singlet, nematic, partially magnetic and ferromagnetic phases in the magnetic phase diagrams.

Internal delensing of Planck CMB temperature and polarization

description: We present a first internal delensing of CMB maps, both in temperature and polarization, using the public foreground-cleaned (SMICA) Planck 2015 maps. After forming quadratic estimates of the lensing potential, we use the corresponding displacement field to undo the lensing on the same data. We build differences of the delensed spectra to the original data spectra specifically to look for delensing signatures. After taking into account reconstruction noise biases in the delensed spectra, we find an expected sharpening of the power spectrum acoustic peaks with a delensing efficiency of $29\,\%$ ($TT$) $25\,\%$ ($TE$) and $22\,\%$ ($EE$). The detection significance of the delensing effects is very high in all spectra: $12\,σ$ in $EE$ polarization; $18\,σ$ in $TE$; and $20\,σ$ in $TT$. The null hypothesis of no lensing in the maps is rejected at $26\,σ$. While direct detection of the power in lensing $B$-modes themselves is not possible at high significance at Planck noise levels, we do detect (at $4.5\,σ$ under the null hypothesis) delensing effects in the $B$-mode map, with $7\,\%$ reduction in lensing power. Our results provide a first demonstration of polarization delensing, and generally of internal CMB delensing, and stand in agreement with the baseline $Λ$CDM Planck 2015 cosmology expectations.

description: Diverse Regioni italiane hanno promulgato leggi per la salvaguardia dei rispettivi patrimoni linguistici. Questo lavoro sottolinea alcune caratteristiche di tali leggi e si interroga in particolare sul significato della denominazione “patrimonio linguistico napoletano”, proponendo che tale etichetta possa riferirsi all’insieme dei dialetti della Campania. Inoltre viene affermata la necessità di riflettere su forme e obiettivi specifici delle iniziative di tutela. L’ipotesi qui formulata è che, al di là di semplici enunciazioni di principio, sia opportuno prevedere quattro diverse fasi: 1. Fruizione (degli usi artistici connessi ai dialetti); 2. Informazione (attraverso una divulgazione qualificata); 3. Formazione (anche attraverso una riflessione sui dialetti proposta nella didattica); 4. Documentazione / ricerca.

Search for supersymmetry in multijet events with missing transverse momentum in proton-proton collisions at 13 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2017
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for supersymmetry is presented based on multijet events with large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of sqrt(s) = 13 TeV. The data, corresponding to an integrated luminosity of 35.9 inverse femtobarns, were collected with the CMS detector at the CERN LHC in 2016. The analysis utilizes four-dimensional exclusive search regions defined in terms of the number of jets, the number of tagged bottom quark jets, the scalar sum of jet transverse momenta, and the magnitude of the vector sum of jet transverse momenta. No evidence for a significant excess of events is observed relative to the expectation from the standard model. Limits on the cross sections for the pair production of gluinos and squarks are derived in the context of simplified models. Assuming the lightest supersymmetric particle to be a weakly interacting neutralino, 95% confidence level lower limits on the gluino mass as large as 1800 to 1960 GeV are derived, and on the squark mass as large as 960 to 1390 GeV, depending on the production and decay scenario.

Minoranze linguistiche e dialetti

description: Il dialettologo, senza porsi problemi di denominazione, studia le lingue locali come lingue naturali umane osservate dal punto di vista della variabilità. Nel quadro odierno, meritevoli di tutela non sono solo le cosiddette “lingue di minoranza”, ma sono tutte quelle lingue locali la cui comunità di parlanti rischia di disgregarsi per i movimenti migratori o per una prassi comunicativa che, anche nel parlato informale, privilegia l’italiano o altre lingue sovralocali. Quindi l’offerta di tutela da parte delle istituzioni va rivolta a tutti i dialetti locali e può avere un luogo privilegiato nelle scuole: tuttavia, la salvaguardia non può essere praticata con l’insegnamento formale del dialetto, ma attraverso il confronto con altre lingue.

description: A binary system of identical corotating Kerr sources is studied after deriving the corresponding 3-parametric asymptotically flat exact solution. Both sources are apart from each other by means of a massless strut (conical singularity). In the context of black holes, the analytical functional form of each horizon σ is expressed in terms of arbitrary Komar physical parameters: mass M, angular momentum J (with parallel spin), and the coordinate distance R between the center of each horizon. Later on, all the thermodynamical properties related to the horizon are depicted by concise formulae. Finally, the extreme limit case is obtained as a 2-parametric subclass of Kinnersley-Chitre metric.

Giovan Battista Basile tra “favole” campanilistiche e realtà documentaria
Creators: name: D'Alessandro, Domenico Antonio
Publisher: name: Rivista del Dizionario Etimologico e Storico del Napoletano
Year: 2023

description: Questo saggio esamina come sia nata e si sia diffusa la falsa credenza che Giovan Battista Basile - il celebre autore de Lo Cunto de li Cunti - sia nato a Giugliano (Campania, Italia) il 15 febbraio 1566, come secondogenito di Giovanni Giacomo Basile e Laudonia Milone. Il "Cavalier" Basile morì effettivamente a Giugliano il 23 febbraio 1632, a causa di una virulenta epidemia di difterite, dopo aver ricoperto per pochi giorni la carica di governatore feudale di Giugliano. Sostenuta da un sacerdote locale già nel 1715, e successivamente da giornalisti locali, la tesi errata - basata su un caso di omonimia che in effetti svilisce la vera identità dei genitori naturali di Basile - è stata però ulteriormente ripresa negli anni Settanta-Ottanta dai media. Questo saggio confuta definitivamente la falsa "tesi di Giugliano" raccogliendo informazioni estremamente dettagliate da diverse fonti (opere di Basile, lettere e nuovi documenti inediti). Attraverso queste ricerche, si può concludere definitivamente che il famoso scrittore Giovan Battista e la nota cantante Andreana, sua sorella, nacquero rispettivamente nel 1583 e nel 1586 a Napoli da Francesco Antonio Basile e Cornelia Daniele e furono entrambi registrati nella parrocchia di Sant'Anna di Palazzo.

Light Dark Matter through Assisted Annihilation

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this paper we investigate light dark matter scenarios where annihilation to Standard Model particles at tree-level is kinematically forbidden. In such cases annihilation can be aided by massive Standard Model-like species, called {\it assisters}, in the initial state that enhances the available phase space opening up novel tree-level processes. We investigate the feasibility of such non-standard {\it assisted annihilation} processes to reproduce the observed relic density of dark matter. We present a simple scalar dark matter - scalar assister model where this is realised. We find that if the dark matter and assister are relatively degenerate the required relic density can be achieved for a keV-MeV scale dark matter. We briefly discuss the cosmological constraints on such dark matter scenarios.

description: Il disegno di legge regionale per la tutela del patrimonio linguistico campano lascia aperti molti interrogativi sia in relazione all'interpretazione dell'effettivo campo di applicazione del disegno di legge (comprende solo il dialetto urbano di Napoli o anche tutti gli altri dialetti della regione?) sia in relazione alle possibili misure che possono o devono essere adottate in vista di tale tutela. La complessità dialettale della Campania, la sua storia e la sua denominazione, le dinamiche che i dialetti stanno attualmente mostrando, le loro tendenze alla convergenza reciproca e a un certo grado di ibridazione con l'italiano, sono tra le principali questioni che vengono discusse in questo documento. In particolare, viene preso in considerazione anche il ruolo che l'insegnamento scolastico può svolgere nei confronti dei dialetti e della loro sopravvivenza, descrivendo le possibili azioni che potrebbero o dovrebbero essere intraprese e i loro evidenti limiti dovuti a una serie di fattori teorici e pratici.

description: We consider a particular set of two-point functions in the setting of N = 4 SYM with a defect, dual to the fuzzy-funnel solution for the probe D5-D3-brane system. The two-point functions in focus involve a single trace operator in the SU(2)-subsector of arbitrary length and a length-two operator built out of any scalars. By interpreting the contractions as a spin-chain operator, simple expressions were found for the leading contribution to the two-point functions, mapping them to earlier known formulas for the one-point functions in this setting.

At a fixed stellar mass, galaxies with higher $D_n4000$ have larger velocity dispersions and smaller sizes. $D_n4000$ is a proxy for stellar population age, thus these trends suggest that older galaxies typically have larger velocity dispersions and smaller sizes. We combine velocity dispersion and size into a dynamical mass estimator, $σ^2 R$. At a fixed stellar mass, $σ^2 R$ depends on $D_n4000$. The Sérsic index is also correlated with $D_n4000$. The dependence of $σ^2 R$ and Sérsic index on $D_n4000$ suggests that quiescent galaxies are not structurally homologous systems. We derive an empirical correction for non-homology which is consistent with the analytical correction derived from the virial theorem. After accounting for non-homologous galactic structure, we measure $M_\ast \propto M_d^{0.998 \pm 0.004}$ where $M_\ast$ is the stellar mass and $M_d$ is the dynamical mass derived from the velocity dispersion and size; stellar mass is directly proportional to dynamical mass. Quiescent galaxies appear to be in approximate virial equilibrium and deviations of the fundamental plane parameters from the expected virial relation may result from mass-to-light ratio variations, selection effects and the non-homology of quiescent galaxies. We infer the redshift evolution of velocity dispersion and size for galaxies in our sample assuming purely passive evolution. The inferred evolution is inconsistent with direct measurements at higher redshifts. Thus quiescent galaxies do not passively evolve. Quiescent galaxies have properties consistent with standard galaxy formation in $Λ$CDM. They form at different epochs and evolve modestly increasing their size, velocity dispersion and Sérsic index after they cease star formation.

description: We provide a bound on a natural distance between finitely and infinitely supported elements of the unit sphere of $\ell^2(\mathbb{N}^*)$, the space of real valued sequences with finite $\ell^2$ norm. We use this bound to estimate the 2-Wasserstein distance between random variables which can be represented as linear combinations of independent random variables. Our results are expressed in terms of a discrepancy measure which is related to Nourdin and Peccati's Malliavin-Stein method. The main area of application of our results is towards the computation of quantitative rates of convergence towards elements of the second Wiener chaos. After particularizing our bounds to this setting and comparing them with the available literature on the subject (particularly the Malliavin-Stein method for Variance-gamma random variables), we illustrate their versatility by tackling three examples: chi-squared approximation for second order $U$-statistics, asymptotics for sequences of quadratic forms and the behavior of the generalized Rosenblatt process at extreme critical exponent.

description: Modification of gravity due to the curvature dependent term in the gravitational baryogenesis scenario is considered. It is shown that this term leads to the fourth order differential equation of motion for the curvature scalar instead of the algebraic one of General Relativity (GR). The fourth order gravitational equations are generically unstable with respect to small perturbations. Non-linear in curvature terms may stabilize the solution but the magnitude of the stabilized curvature scalar would be much larger than that dictated by GR, so the standard cosmology would be strongly distorted.

description: Characterization of the atmospheres of transiting exoplanets relies on accurate measurements of the extent of the optically thick area of the planet at multiple wavelengths with a precision $\lesssim$100 parts per million (ppm). Next-generation instruments onboard the James Webb Space Telescope (JWST) are expected to achieve $\sim$10 ppm precision for several tens of targets. A similar precision can be obtained in modelling only if other astrophysical effects, including the stellar limb-darkening, are accounted for properly. In this paper, we explore the limits on precision due to the mathematical formulas currently adopted to approximate the stellar limb-darkening, and to the use of limb-darkening coefficients obtained either from stellar-atmosphere models or empirically. We propose a new limb-darkening law with two coefficients, `power-2', which outperforms other two-coefficient laws adopted in the literature in most cases, and particularly for cool stars. Empirical limb-darkening based on two-coefficient formulas can be significantly biased, even if the light-curve residuals are nearly photon-noise limited. We demonstrate an optimal strategy to fitting for the four-coefficients limb-darkening in the visible, using prior information on the exoplanet orbital parameters to break some of the degeneracies that otherwise would prevent the convergence of the fit. Infrared observations taken with the James Webb Space Telescope (JWST) will provide accurate measurements of the exoplanet orbital parameters with unprecedented precision, which can be used as priors to improve the stellar limb-darkening characterization, and therefore the inferred exoplanet parameters, from observations in the visible, such as those taken with Kepler/K2, JWST, other past and future instruments.

description: In this paper, using the holographic prescription, we study multispin bound states and their dispersion relations over the $ κ$-deformed $ AdS_{3}\times S^{3} $ background. In the first part of our analysis, considering the conformal gauge conditions (associated with the Polyakov action) we explore the dispersion relation associated with spin two bound states at strong coupling. We solve corresponding world-sheet fluctuations and compute all the conserved quantities associated with the stringy dynamics over the deformed background. In the second part of our analysis, we perform similar analysis for spin three configurations. In both cases, we observe the emergence of non trivial background deformation that vanishes in the limit, $ κ\rightarrow 0$.

description: We use the poor man's scaling approach to study the phase boundaries of a pair of quantum impurity models featuring a power-law density of states $ρ(ω)\propto|ω|^r$ that gives rise to quantum phase transitions between local-moment and Kondo-screened phases. For the Anderson model with a pseudogap (i.e., $r>0$), we find the phase boundary for (a) $01$, where the phases are separated by first-order quantum phase transitions. For the particle-hole-symmetric Kondo model with easy-axis or easy-plane anisotropy of the spin exchange, the phase boundary and scaling trajectories are obtained for both $r>0$ and $r<0$ (the later case describing a density of states that diverges at the Fermi energy). Comparison with nonperturbative results from the numerical renormalization group shows that poor man's scaling correctly describes the shape of phase boundaries expressed as functional relations between model parameters.

description: In [7] Krotov and Hopfield suggest a generalized version of the well-known Hopfield model of associative memory. In their version they consider a polynomial interaction function and claim that this increases the storage capacity of the model. We prove this claim and take the "limit" as the degree of the polynomial becomes infinite, i.e. an exponential interaction function. With this interaction we prove that model has an exponential storage capacity in the number of neurons, yet the basins of attraction are almost as large as in the standard Hopfield model.

description: This review paper summarizes the current state-of-art and challenges for the future developments of fiber-reinforced composites for structural applications with multifunctional capabilities. After a brief analysis of the reasons of the successful incorporation of fiber-reinforced composites in many different industrial sectors, the review analyzes three critical factors that will define the future of composites. The first one is the application of novel fiber-deposition and preforming techniques together with innovative liquid moulding strategies, which will be combined by optimization tools based on novel multiscale modelling approaches, so fiber-reinforced composites with optimized properties can be designed and manufactured for each application. In addition, composite applications will be enhanced by the incorporation of multifunctional capabilities. Among them, electrical conductivity, energy storage (structural supercapacitors and batteries) and energy harvesting (piezoelectric and solar energy) seem to be the most promising ones.

description: Cloud computing is a widely adopted paradigm in the software industry. The ability to adapt the provisioned resources for an application based on the actual demand is called auto-scaling. Auto-scaling is crucial to keep costs within limits while ensuring sufficient performance. Effective auto-scaling is a multi-dimensional problem and an active area of research. The industry standard for auto-scaling is static thresholds based on low-level metrics such as CPU utilization, while researchers are experimenting with applying Machine Learning techniques to auto-scaling. Static thresholds are hard to set up and need to be manually corrected, and low-level metrics are disconnected from the business goals. On the other hand, Reinforcement Learning is a popular approach to autonomously learning an auto-scaling policy. While promising, RL introduces new problems to the auto-scaling domain, such as a lack of explainability and interpretability, complexity, long learning phases, and bad worst-case performance. We aim to find ways to efficiently auto-scale while bridging the gap between auto-scaling and business goals without the undesirable properties of RL solutions.This thesis presents two approaches to auto-scaling, Extended-Q-Threshold, and HPA-Q-Threshold, both building upon Q-Threshold, an auto-scaling system from the literature. Our auto-scalers are integrated into the Polaris framework, built with a flexible architecture in mind. We extend and adapt Q-Threshold, an approach to auto-scaling where the RL agent controls the usually static threshold, effectively making it dynamic. Our adaptations tackle experimentally identified shortcomings of the Q-Threshold approach. Furthermore, we generalize the approach and apply different scaling metrics and rewards. Thus, we enable the further development and evaluation of this promising approach.We show how a modern, flexible auto-scaler can be integrated with the Polaris framework and run in a Kubernetes cluster. Our experiments evaluate the effectiveness of our proposed adaptations and prove that some are necessary to prevent the identified issues of Q-Threshold. In contrast, others must be carefully assessed and tested, such as different scaling metrics and reward definitions. Overall, the adaptations help ensure the interpretability of the auto-scaler by utilizing a very lightweight implementation of RL. Furthermore, our auto-scaler possesses other positive characteristics, such as limiting the worst-case and guaranteeing acceptable early-stage performance.

description: We show that the eight-dimensional instanton solution, which satisfies the self-duality equation $F \wedge F = *_8 F \wedge F$, realizes the static Skyrmion configuration in eight dimensions through the Atiyah-Manton construction. The relevant energy functional of the Skyrme field is obtained by the formalism developed by Sutcliffe. By comparing the Skyrmion olution associated with the extreme of the energy, with the Atiyah-Manton solution constructed by the instantons, we find that they agree with high accuracy. This is a higher-dimensional analogue of the Atiyah-Manton construction of Skyrmions in four dimensions. Our result indicates that the instanton/Skyrmion correspondence seems to be an universal property in $4k \ (k=1, 2, \ldots)$ dimensions.
