Metakognition
Förderstrategie

description: Die Metakognition ist eine Voraussetzung für reflektiertes und strategisches Lernen. In der Forschung wird davon ausgegangen, dass metakognitive Kompetenzen eine entscheidende Rolle für Lernleistung und Lernerfolg spielen. Der Ansatzpunkt dieser Entwicklungsarbeit ist daher die Annahme, dass ein Lernarrangement, das metakognitive Fähigkeiten fördert, positive Auswirkungen auf die Lernleistung haben sollte. Im Rahmen der vorliegenden Masterarbeit wird untersucht, wie mithilfe eines strukturierten Lerntagebuches die Metakognition von Lernenden gefördert werden kann und wie sich die Mathematikleistungen in diesem Zeitraum verändern. Hierzu führten 18 Jugendliche einer 8. Klasse 20 Wochen lang im Rahmen von «Lernpass plus»-Lektionen ein strukturiertes Lerntagebuch. Zur Messung von Veränderungen in den Mathematikleistungen wurden vor und nach der Lerntagebuch-Intervention Orientierungstests und der Mathematik-Kurztest (MKT) für die 8. Klasse durchgeführt. Zudem füllten die Lernenden zu Beginn und zum Schluss des Projektes einen Erhebungsfragebogen zur Erfassung der Motivation, Zielorientierung, Selbstwirksamkeit, Emotion und zu den metakognitiven Kompetenzen aus. Die Durchführung des Projektes hat gezeigt, dass Lerntagebücher Struktur in den Lernprozess bringen. Ihre Nutzung bedarf jedoch einer intensiven Anleitung und sorgfältigen Einführung. Die Form des Lerntagebuchs soll auf die Bedürfnisse der Klasse oder sogar der einzelnen Lernenden zugeschnitten sein. Es wurde mit einer Version gestartet, die aufgrund der Rückmeldungen der Schüler_innen sowie des pädagogischen Teams zweimal verändert und angepasst wurde, wobei die Jugendlichen selbst wählen konnten, mit welcher Version sie arbeiten möchten. Anhand der Tests konnte bei allen Schülerinnen und Schülern eine Leistungssteigerung im Fach Mathematik festgestellt werden. Mithilfe des Lerntagebuches, des Fragebogens und der dokumentierten Beobachtungen konnte zudem festgestellt werden, dass die Klasse in den Bereichen Motivation, Zielorientierung, Selbstwirksamkeit, Emotion und Metakognition während des beobachteten Zeitraumes Fortschritte gemacht haben. Obwohl in der Klasse eine Leistungssteigerung im Fach Mathematik feststellbar war, lässt sich aufgrund einer fehlenden Kontrollgruppe keinen direkten Zusammenhang zwischen der Förderung der Metakognition und der Mathematikleistung ableiten. Es kann aber davon ausgegangen werden, dass der Fokus auf die Metakognition die Leistungssteigerung nicht gehemmt, sondern eher unterstützt hat. Die Förderung der metakognitiven Kompetenzen sowie das Führen des Lerntagebuchs werden weitergeführt. Die Ergebnisse und Erkenntnisse sollen daher als eine Zwischenbilanz verstanden werden.

description: We report experimental evidence of a remarkable spontaneous time reversal symmetry breaking in two dimensional electron systems formed by atomically confined doping of phosphorus (P) atoms inside bulk crystalline silicon (Si) and germanium (Ge). Weak localization corrections to the conductivity and the universal conductance fluctuations were both found to decrease rapidly with decreasing doping in the Si:P and Ge:P $δ-$layers, suggesting an effect driven by Coulomb interactions. In-plane magnetotransport measurements indicate the presence of intrinsic local spin fluctuations at low doping, providing a microscopic mechanism for spontaneous lifting of the time reversal symmetry. Our experiments suggest the emergence of a new many-body quantum state when two dimensional electrons are confined to narrow half-filled impurity bands.

description: Les pratiques d’enseignement jouent un rôle non négligeable dans le processus du décrochage scolaire, et sont, contrairement à de nombreux autres facteurs (familiaux ou personnels), des éléments sur lesquels les enseignants peuvent agir. En effet, leurs gestes et attitudes professionnelles ont une influence sur le risque de décrochage de leurs élèves. Dès lors, comment mieux comprendre leur travail et leurs préoccupations avec les élèves à risque de décrochage pour leur permettre d’être les plus efficaces possible dans leurs actions auprès de cette population à risque ? À travers une recherche qualitative, basée sur des entretiens avec des enseignants ordinaires de français du canton de Vaud (de 7 à 11H), nous relevons leurs représentations et leurs affects liés aux situations vécues avec ces élèves à risque et aux perceptions de leur travail d’enseignants auprès de ceux-ci. Il ressort de cette étude que les attitudes et les pratiques peuvent différer considérablement d’un enseignant de français à l’autre par rapport à ces élèves. De manière générale, les enseignants sont sensibles à la qualité de la relation entre enseignant-élèves et démontrent une attitude positive aux pratiques différenciatrices. Ceci va dans le sens des pratiques efficaces pour protéger du décrochage. En ce qui concerne la discipline français, il apparaît que la lecture soit particulièrement porteuse de motivation et d’engagement tant du côté des enseignants que des élèves. Bien que des éléments positifs du travail avec cette population d’élèves soient relevés, il semble que les frustrations et les difficultés rencontrées peuvent influer négativement sur le sentiment d’autoefficacité de l’enseignant, sur sa motivation et sur son plaisir. Ainsi, nous proposons un modèle motivationnel permettant de mieux comprendre l’influence réciproque enseignant-élèves qui agit sur l’accrochage des élèves à l’école. Pour finir, des pistes comme les alliances éducatives et la formation des enseignants nous permettent d’envisager une influence positive globale afin de minimiser le décrochage scolaire.

description: Although statistical evidence is not overwhelming, possible support for an approximately 35 million year periodicity in the crater record on Earth could indicate a nonrandom underlying enhancement of meteorite impacts at regular intervals. A proposed explanation in terms of tidal effects on Oort cloud comet perturbations as the Solar System passes through the galactic midplane is hampered by lack of an underlying cause for sufficiently enhanced gravitational effects over a sufficiently short time interval and by the time frame between such possible enhancements. We show that a smooth dark disk in the galactic midplane would address both these issues and create a periodic enhancement of the sort that has potentially been observed. Such a disk is motivated by a novel dark matter component with dissipative cooling that we considered in earlier work. We show how to evaluate the statistical evidence for periodicity by input of appropriate measured priors from the galactic model, justifying or ruling out periodic cratering with more confidence than by evaluating the data without an underlying model. We find that, marginalizing over astrophysical uncertainties, the likelihood ratio for such a model relative to one with a constant cratering rate is 3.0, which moderately favors the dark disk model. Our analysis furthermore yields a posterior distribution that, based on current crater data, singles out a dark matter disk surface density of approximately 10 solar masses per square parsec. The geological record thereby motivates a particular model of dark matter that will be probed in the near future.

description: (abridged) Stable circumbinary discs around evolved post-Asymptotic Giant branch (post-AGB) binary systems show many similarities with protoplanetary discs around young stellar objects. These discs can provide constraints on both binary evolution and the formation of macrostructures within circumstellar discs. Here we focus on one post-AGB binary system: IRAS08544-4431. We aim to refine the physical model of IRAS08544-4431 with a radiative transfer treatment and continue the near-infrared and mid-infrared interferometric analysis covering the H-, K-, L-, and N-bands. We aim to capture the previously detected amount of over-resolved flux and the radial intensity profile at and beyond the inner dust disc rim to put constraints on the physical processes in the inner disc regions. We used a Monte Carlo radiative transfer code to investigate the physical structure of the disc by reproducing both the photometry and the multi-wavelength infrared interferometric data set. We developed a strategy to identify the models which perform best to reproduce our data set. We found a family of models that successfully fit the infrared photometric and interferometric data in all bands. Some over-resolved flux component was recovered in all bands but the optimised models still fall short to explain all the over-resolved flux. This suggests that another dusty structure within the system plays a role. Multi-wavelength infrared interferometric observations of circumstellar discs allow to study the inner disc regions in unprecedented detail. The refined physical models can reproduce most of the investigated features, including the photometric characteristics, the radial extent, and the overall shape of the visibility curves. Our multi-wavelength interferometric observations combined with photometry show that the disc is similar to protoplanetary discs with similar dust masses and efficient dust growth.

description: The J-PET detector, which consists of inexpensive plastic scintillators, has demonstrated its potential in the study of fundamental physics. In recent years, a prototype with 192 plastic scintillators arranged in 3 layers has been optimized for the study of positronium decays. This allows performing precision tests of discrete symmetries (C, P, T) in the decays of positronium atoms. Moreover, thanks to the possibility of measuring the polarization direction of the photon based on Compton scattering, the predicted entanglement between the linear polarization of annihilation photons in positronium decays can also be studied. Recently, a new J-PET prototype was commissioned, based on a modular design of detection units. Each module consists of 13 plastic scintillators and can be used as a stand-alone, compact and portable detection unit. In this paper, the main features of the J-PET detector, the modular prototype and their applications for possible studies with positron and positronium beams are discussed. Preliminary results of the first test experiment performed on two detection units in the continuous positron beam recently developed at the Antimatter Laboratory (AML) of Trento are also reported.

description: Dans les classes spécialisées accueillant des élèves ayant une déficience intellectuelle, il n’est pas rare que les enseignants soient confrontés à des comportements-défis. L’accompagnement de ces élèves devient plus compliqué pour l’enseignant, car ces situations peuvent générer du stress et de l’incompréhension. Une démarche structurée comme l’évaluation fonctionnelle va permettre d’entrevoir des pistes compréhensives des comportements-défis en analysant les facteurs environnementaux et personnels de la personne (Albin et al., 1996). Les compétences et les intérêts de l’élève vont constituer une ressource dans la mise en place d’une intervention basée sur le soutien au comportement positif. Selon Sugai et al., (2000), ce modèle est pertinent, car il a un impact sur la diminution des comportements-défis ainsi que sur la qualité de vie de l’élève, de son entourage et ses apprentissages. Cette recherche met l’accent sur l’évaluation fonctionnelle pratiquée en classe spécialisée avec un élève ayant une déficience intellectuelle. Des observations des comportements-défis de l’élève ont été réalisés avant, pendant et après l’intervention afin de mesurer l’efficacité du plan de soutien au comportement positif.

description: According to the Hugenholtz-Van Hove theorem, the nuclear symmetry energy $S(ρ)$ and its slope $L(ρ)$ at arbitrary densities can be decomposed in terms of the density and momentum dependence of the single-nucleon potentials in isospin-asymmetric nuclear matter which are potentially accessible to experiment. We quantify the correlations between several well-known isovector observables and $L(ρ)$ to locate the density range in which each isovector observable is most sensitive to the density dependence of the $S(ρ)$. We then study the correlation coefficients between those isovector observables and all the components of the $L(ρ)$. The neutron skin thickness of $^{208}$Pb is found to be strongly correlated with the $L(ρ)$ at a subsaturation density of $ρ= 0.59 ρ_0$ through the density dependence of the first-order symmetry potential. Neutron star radii are found to be strongly correlated with the $L(ρ)$ over a wide range of supra-saturation densities mainly through both the density and momentum dependence of the first-order symmetry potential. Finally, we find that although the crust-core transition pressure has a complex correlation with the $L(ρ)$, it is strongly correlated with the momentum derivative of the first-order symmetry potential, and the density dependence of the second-order symmetry potential.

description: Edible vaccines, a concept introduced by Charles Arentzen in 1990, are a form of oral vaccination that utilize transgenic plants or animals to stimulate the immune system. These vaccines have the potential to greatly impact global vaccine programs, particularly in developing countries. In 1998, the National Institute of Allergy and Infectious Diseases approved the use of edible vaccines due to their impressive ability to elicit an immune response. Edible vaccines offer several advantages, including cost-effectiveness, non-invasiveness, convenience, safety, and ease of administration. They are predominantly targeted against viruses and bacteria that cause harmful illnesses in humans, animals, and poultry. However, no edible vaccine has been approved by the United States Food and Drug Administration (USFDA) as they fall under the category of genetically modified crops.

description: In this article, we study an exponential decay for the gas of bosons with strong repulsive delta interactions from a double-well potential. We consider an exactly solvable model comprising an infinite wall and two Dirac delta barriers. We explore its features both within the exact method and with the resonance expansion approach. The study reveals the effect of the splitting barrier on the decay rate in dependence on the number of particles. Among other things, we find that the effect of the splitting barrier on the decay rate is most pronounced in systems with odd particle numbers. During exponential decay, the spatial correlations in an internal region are well captured by the "radiating state".

description: The equation of state with quantum statistics corrections is used for particle number fluctuations $ω$ of isotopically symmetric nuclear matter with interparticle van der Waals and Skyrme local density interactions. The fluctuations, $ω\propto 1/\mathcal{K}$, are analytically derived through the isothermal incompressibility $\mathcal{K}$ at first order over a small quantum-statistics parameter. Our approximate analytical results appear to be in good agreement with the results of accurate numerical calculations. These results are also close to those obtained by using more accurate Tolman and Rowlinson expansions of the incompressibility $\mathcal{K}$ near the critical point. A more general formula for fluctuations $ω$, improved at the critical point, was obtained for a finite particle-number average $\langle N \rangle$ by neglecting, for simplicity, small quantum statistics effects. It is shown that for a large dimensionless parameter, $α\propto \mathcal{K}^2\langle N \rangle/\mathcal{K}^{\prime\prime} $, where $\mathcal{K}^{\prime\prime}$ is the second derivative of the incompressibility $\mathcal{K}$ as function of the average particle density $n$, far from the critical point ($α\gg 1$), one finds the traditional asymptote, $ω\propto 1/\mathcal{K}$, for the fluctuations $ω$. For a small parameter, $α\ll 1$, near the critical point, where $\mathcal{K}=0$ and $α=0$, one obtains another asymptote of $ω$. These fluctuations, having a maximum near the critical point as function of the average density $n$, for finite values of $\langle N \rangle$ are finite and relatively small, in contrast to the results of the traditional calculations.

description: We present analytical results for the distribution of the number of cycles in directed and undirected random 2-regular graphs (2-RRGs) consisting of $N$ nodes. In directed 2-RRGs each node has one inbound link and one outbound link, while in undirected 2-RRGs each node has two undirected links. Since all the nodes are of degree $k=2$, the resulting networks consist of cycles. These cycles exhibit a broad spectrum of lengths, where the average length of the shortest cycle in a random network instance scales with $\ln N$, while the length of the longest cycle scales with $N$. The number of cycles varies between different network instances in the ensemble, where the mean number of cycles $\langle S \rangle$ scales with $\ln N$. Here we present exact analytical results for the distribution $P_N(S=s)$ of the number of cycles $s$ in ensembles of directed and undirected 2-RRGs, expressed in terms of the Stirling numbers of the first kind. In both cases the distributions converge to a Poisson distribution in the large $N$ limit. The moments and cumulants of $P_N(S=s)$ are also calculated. The statistical properties of directed 2-RRGs are equivalent to the combinatorics of cycles in random permutations of $N$ objects. In this context our results recover and extend known results. In contrast, the statistical properties of cycles in undirected 2-RRGs have not been studied before.

description: We develop a theory for the current-voltage characteristics of diffusive superconductor-normal metal-superconductor Josephson junctions with resistive interfaces and the distance between the electrodes smaller than the superconducting coherence length. The theory allows for a quantitative analytical and numerical analysis in the whole range of the interface transparencies and asymmetry. We focus on the regime of large interface resistance compared to the resistance of the normal region, when the electron-hole dephasing in the normal region is significant and the finite length of the junction plays a role. In the limit of strong asymmetry we find pronounced current structures at the combination subharmonics of $Δ+Δ_g$, where $Δ_g$ is the proximity minigap in the normal region, in addition to the subharmonics of the energy gap $2Δ$ in the electrodes. In the limit of rather transparent interfaces, our theory recovers a known formula for the current in a short mesoscopic connector - a convolution of the current through a single-channel point contact with the transparency distribution for an asymmetric double-barrier potential.

description: The nonequilibrium Dyson (or Kadanoff-Baym) equation, which is an equation of motion with long-range memory kernel for real-time Green functions, underlies many numerical approaches based on the Keldysh formalism. In this paper we map the problem of solving the Dyson equation in real-time onto a noninteracting auxiliary Hamiltonian with additional bath degrees of freedom. The solution of the auxiliary model does not require the evaluation of a memory kernel and can thus be implemented in a very memory efficient way. The mapping is derived for a self-energy which is local in space and is thus directly applicable within nonequilibrium dynamical mean-field theory (DMFT). We apply the method to study the interaction quench in the Hubbard model for an optical lattice with a narrow confinement, using inhomogeneous DMFT in combination with second-order weak-coupling perturbation theory. We find that, although the quench excites pronounced density oscillations, signatures of the two-stage relaxation similar to the homogeneous system can be observed by looking at the time-dependent occupations of natural orbitals.

description: Studies of exoplanetary atmospheres have found no definite correlations between observed high altitude aerosols and other system parameters. This could be, in part, because of the lack of homogeneous exoplanet samples for which specific parameters can be isolated and inspected. Here we present a set of seven exoplanets with very similar system parameters. We analyze existing photometric timeseries, Gaia parallax, and high-resolution spectroscopic data to produce a new set of homogeneous stellar, planetary, and orbital parameters for these systems. With this we confirm that most measured parameters for all systems are very similar, except for the host stars' metallicities and possibly high energy irradiation levels, which require UV and X-ray observations to constrain. From the sample, WASP-6b, WASP-96b and WASP-110b, have observed transmission spectra that we use to estimate their aerosol coverage levels using the Na I doublet 5892.9Å. We find a tentative correlation between the metallicity of the host stars and the planetary aerosol levels. The trend we find with stellar metallicity can be tested by observing transmission spectra of the remaining planets in the sample. Based on our prediction, WASP-25b and WASP-55b should have higher levels of aerosols than WASP-124b and HATS-29b. Finally, we highlight how targeted surveys of alike planets like the ones presented here might prove key for identifying driving factors for atmospheric properties of exoplanets in the future and could be used as a sample selection criterium for future observations with e.g. JWST, ARIEL, and the next generation of ground-based telescopes.

We emphasize how it can be expressed in terms of gauge-invariant condensates on the light cone, which are amenable to novel sum rules and Euclidean techniques. For the phenomenologically interesting value of alpha_s=0.3, the NLO correction represents a 20% increase and has a functional form similar to the LO result.

description: The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these elusive objects from radial velocity monitoring of self-luminous directly imaged planets. This technique is now possible thanks to the development of dedicated instruments combining the power of high-resolution spectroscopy and high-contrast imaging. First, we demonstrate a sensitivity to satellites with a mass ratio of 1-4% at separations similar to the Galilean moons from observations of a brown-dwarf companion (HR 7672 B; Kmag=13; 0.7" separation) with the Keck Planet Imager and Characterizer (KPIC; R~35,000 in K band) at the W. M. Keck Observatory. Current instrumentation is therefore already sensitive to large unresolved satellites that could be forming from gravitational instability akin to binary star formation. Using end-to-end simulations, we then estimate that future instruments such as MODHIS, planned for the Thirty Meter Telescope, should be sensitive to satellites with mass ratios of ~1e-4. Such small moons would likely form in a circumplanetary disk similar to the Jovian satellites in the solar system. Looking for the Rossiter-McLaughlin effect could also be an interesting pathway to detecting the smallest moons on short orbital periods. Future exomoon discoveries will allow precise mass measurements of the substellar companions that they orbit and provide key insight into the formation of exoplanets. They would also help constrain the population of habitable Earth-sized moons orbiting gas giants in the habitable zone of their stars.

description: Ce travail vise la compréhension des jugements que peuvent avoir certains enseignants ordinaires à l’égard de leurs élèves. En effet, il n’est pas rare d’entendre des commentaires parfois à la limite de la déontologie de la part de certains enseignants. Qu’est-ce qui pousse certains enseignants à juger leurs élèves ? Sur quelles normes basent-ils leur jugement ? D’où viens ce besoin de dire des choses parfois dures sur leurs élèves ? Telles sont les questions que je me suis posées dans cette recherche. Pour tenter de comprendre l’origine de tels comportements, je me suis basée sur des entretiens réalisés avec des enseignants primaires, dans une position proche de la sociologie clinique. L’analyse de ces entretiens est appuyée par des apports théoriques et par des réflexions personnelles faites durant ma pratique. Cette recherche est construite sur un fil conducteur, afin de suivre l’évolution de ma compréhension et de mes pensées. Ainsi, partant d’une indignation personnelle, ma réflexion a évolué vers un but de compréhension de l’Autre et de soi-même Des thèmes se retrouvent régulièrement dans le discours des enseignants, notamment les comportements divers des élèves ou la fatigue éprouvée au quotidien. Un lien est fait avec les représentations individuelles. La compréhension et la bienveillance sont les mots finaux de cette recherche.

description: When the cosmological "constant" is derived from modern five-dimensional relativity, exact solutions imply that for small systems it scales in proportion to the square of the mass. However, a duality transformation implies that for large systems it scales as the inverse square of the mass.

description: English. The purpose of the presentation is to extend comments for the structuring, writing and publication of scientific literature in order to make it attractive and quotable for other authors. The presentation begins with a description of the kinds of scientific literature, after which follows the exposition of the role of publishers in the task of making visible the works of their authors; the title, the summary and the exposition of the results constitute the sections that most determine if someone starts reading a scientific article. In addition, instructions for the undertaking of mini-reviews are transmitted, in particular, the time required for this; from conception of the idea to writing the first draft of a mini-review manuscript, experience suggests it takes five months for this. Finally, the paper exposes a sequence of steps to make visible on the Internet those works that were published in non-indexed journals. Español. El propósito de la presentación es extender comentarios pertinentes para la estructuración, redacción y publicación de literatura científica en miras de hacerla atractiva y aumentar las probabilidades de que ésta sea citada por otros autores. La ponencia inicia con los tipos y objetivos de la literatura científica, tras lo cual sigue la exposición del protagonismo de las editoriales en cuanto a visibilizar los trabajos de sus autores; indexación, número de citas, motores de búsqueda, índice-H, cuartiles, entre otros, son parte de los términos aportados. Seguidamente, se dan sugerencias puntuales para la redacción de un artículo científico; el título, el resumen y la exposición de los resultados de un trabajo constituyen las secciones que más determinan si alguien inicia con la lectura de éste. Además, se transmiten instrucciones para el emprendimiento de minirrevisiones, en particular, el tiempo requerido para esto; desde la concepción de la idea hasta la redacción del primer borrador del manuscrito de una minirrevisión, la experiencia sugiere que se requieren de cinco meses. Finalmente, la ponencia expone una secuencia de pasos para hacer visible por Internet aquellos trabajos que fueron publicados en revistas no indexadas.

description: The so-called ``non-Fermi liquid'' behavior is very common in strongly correlated systems. However, its operational definition in terms of ``what it is not'' is a major obstacle against theoretical understanding of this fascinating correlated state. Recently there has been much interest in entanglement entropy as a theoretical tool to study non-Fermi liquids. So far explicit calculations have been limited to models without direct experimental realizations. Here we focus on a two dimensional electron fluid under magnetic field and filling fraction $ν=1/2$, which is believed to be a non-Fermi liquid state. Using the composite fermion (CF) wave-function which captures the $ν=1/2$ state very accurately, we compute the second Rényi entropy using variational Monte-Carlo technique and an efficient parallel algorithm. We find the entanglement entropy scales as $L\log L$ with the length of the boundary $L$ as it does for free fermions, albeit with a pre-factor twice that of the free fermion. We contrast the results against theoretical conjectures and discuss the implications of the results.

Accounting for backflow in hydrodynamic-simulation interfaces

description: Methods for building a consistent interface between hydrodynamic and simulation modules is presented. These methods account for the backflow across the hydrodynamic/simulation hyper-surface. The algorithms are efficient, relatively straight-forward to implement, and account for conservation laws across the hyper-surface. The methods also account for the spurious interactions between particles in the backflow and other particles by following the subsequent impact of such particles. Since the number of altered trajectories grows exponentially in time, a cutoff is built into the procedure so that the effects of the backflow are ignored beyond a certain number of collisions

Extraction of Projection Profile, Run-Histogram and Entropy Features Straight from Run-Length Compressed Text-Documents

description: Document Image Analysis, like any Digital Image Analysis requires identification and extraction of proper features, which are generally extracted from uncompressed images, though in reality images are made available in compressed form for the reasons such as transmission and storage efficiency. However, this implies that the compressed image should be decompressed, which indents additional computing resources. This limitation induces the motivation to research in extracting features directly from the compressed image. In this research, we propose to extract essential features such as projection profile, run-histogram and entropy for text document analysis directly from run-length compressed text-documents. The experimentation illustrates that features are extracted directly from the compressed image without going through the stage of decompression, because of which the computing time is reduced. The feature values so extracted are exactly identical to those extracted from uncompressed images.

description: Stellar activity mitigation is one of the major challenges for the detection of earth-like exoplanets in radial velocity (RV) measurements. Several promising techniques are now investigating the use of spectral time-series, to differentiate between stellar and planetary perturbations. In this paper, we present a new version of the Spot Oscillation And Planet (SOAP) 2.0 code that can model stellar activity at the spectral level using graphical processing units (GPUs). We take advantage of the computational power of GPUs to optimise the computationally expensive algorithms behind the original SOAP 2.0 code. We develope GPU kernels that allow to model stellar activity on any given wavelength range. In addition to the treatment of stellar activity at the spectral level, SOAP-GPU also includes the change of spectral line bisectors from center to limb, and can take as input PHOENIX spectra to model the quiet photosphere, spots and faculae, which allow to simulate stellar activity for a wide space in stellar properties. Benchmark calculations show that for the same accuracy, this new code improves the computational speed by a factor of 60 compared with a modified version of SOAP 2.0 that generates spectra, when modeling stellar activity on the full visible spectral range with a resolution of R=115'000. Although the code now includes the variation of spectral line bisector with center to limb angle, the effect on the derived RVs is small. The publicly available SOAP-GPU code allows to efficiently model stellar activity at the spectral level, which is essential to test further stellar activity mitigation techniques working at the level of spectral timeseries not affected by other sources of noise. Besides a huge gain in performance, SOAP-GPU also includes more physics and is able to model different stars than the Sun, from F to K dwarfs, thanks to the use of the PHOENIX spectral library.
