description: Η παρούσα μεταπτυχιακή εργασία αφορά τη μελέτη των απολεπισμένων εργαλείων, κυρίως πυριτόλιθων, της Εποχής του Χαλκού (ΠΕΧ, 3000-1800 π.Χ.) από την Τούμπα Θεσσαλονίκης και έγινε με στόχο τον προσδιορισμό των πηγών προέλευσης των πρώτων υλών που χρησιμοποιήθηκαν για την κατασκευή τους. Για το λόγο αυτό παράλληλα με τα ευρήματα από την ανασκαφή της Τούμπας μελετήθηκαν και γεωλογικά δείγματα αντίστοιχων υλικών από τις περιοχές Βασιλικών και Γαλάτιστας, Θεσσαλονίκης. Αυτή η αρχαιομετρική έρευνα βασίζεται στην μακροσκοπική, μικροσκοπική και γεωχημική μελέτη δειγμάτων. Για το σκοπό αυτό εφαρμόστηκαν η μέθοδος ακτίνων φθορισμού (XRF) και η φασματομετρία μάζας επαγωγικώς συζευγμένου πλάσματος (ICP-MS).
description: The present Master Thesis focuses on the study of lithic artifacts, mainly cherts, from the excavations of the Bronze Age Toumba site (EBA, 3000-1800 B.C.), in Thessaloniki. The aim of this study was to identify the types of the raw materials used for their construction and their provenance. For this reason in addition to the lithic artifacts a number of geological samples from Vasilika and Galatista, Thessaloniki were also examined. This archaeometric research is based on macroscopic, microscopic and geochemical study of these samples. For this reason the research methods included X-ray fluorescence analysis (XRF) and mass spectrometry inductively coupled plasma analysis (ICP-MS).

description: The diverse spatial resolutions, various object types, scales and orientations, and cluttered backgrounds in optical remote sensing images (RSIs) challenge the current salient object detection (SOD) approaches. It is commonly unsatisfactory to directly employ the SOD approaches designed for nature scene images (NSIs) to RSIs. In this paper, we propose a novel Parallel Down-up Fusion network (PDF-Net) for SOD in optical RSIs, which takes full advantage of the in-path low- and high-level features and cross-path multi-resolution features to distinguish diversely scaled salient objects and suppress the cluttered backgrounds. To be specific, keeping a key observation that the salient objects still are salient no matter the resolutions of images are in mind, the PDF-Net takes successive down-sampling to form five parallel paths and perceive scaled salient objects that are commonly existed in optical RSIs. Meanwhile, we adopt the dense connections to take advantage of both low- and high-level information in the same path and build up the relations of cross paths, which explicitly yield strong feature representations. At last, we fuse the multiple-resolution features in parallel paths to combine the benefits of the features with different resolutions, i.e., the high-resolution feature consisting of complete structure and clear details while the low-resolution features highlighting the scaled salient objects. Extensive experiments on the ORSSD dataset demonstrate that the proposed network is superior to the state-of-the-art approaches both qualitatively and quantitatively.

description: Η σύγχρονη κοινωνία χαρακτηρίζεται από ποικιλομορφία και ανομοιογένεια, λόγω των μεγάλων μεταναστευτικών ρευμάτων. Συγκεκριμένα, ο ελλαδικός χώρος, κυρίως λόγω της γεωγραφικής του θέσης, κατέστη σημαντικό κέντρο υποδοχής μεταναστών σε κάθε ιστορική περίοδο. Οι εκφάνσεις της ελληνικής πολυπολιτισμικής κοινωνίας γίνονται άμεσα αντιληπτές κυρίως στον χώρο της εκπαίδευσης. Η ανάγκη για την ενίσχυση μαθητών από διαφορετικά πολιτισμικά και γλωσσικά περιβάλλοντα οδήγησε το ελληνικό κράτος στην υιοθέτηση των αρχών και των μεθόδων της Διαπολιτισμικής Εκπαίδευσης. Βέβαια, η Διαπολιτισμική Εκπαίδευση είχε διαδοθεί πολύ νωρίτερα στην υπόλοιπη Ευρώπη, κυρίως με την δημιουργία διαπολιτισμικών σχολείων, ενώ από πολύ νωρίς γινόταν λόγος για τον τρόπο οργάνωσης και διοίκησης των διαπολιτισμικών αυτών μονάδων. Ειδικότερα τα διαπολιτισμικά σχολεία χαρακτηρίζονται ως «ευαίσθητοι οργανισμοί», αποκομμένοι από τα κλασσικά σχολικά συγκροτήματα. Παράλληλα, έντονος λόγος γίνεται και για τον ρόλο του διευθυντή της διαπολιτισμικής σχολικής μονάδας καθώς και για τις εφαρμογές εσωτερικών πολιτικών όσον αφορά την αντιμετώπιση των πραγματικά ιδιαίτερων αναγκών ενός τέτοιου σχολείου. Εν κατακλείδι, παρακολουθώντας την διαμόρφωση του μαθητικού δυναμικού στη χώρα μας σήμερα αλλά και τις γενικότερες τάσεις που επικρατούν στην εκπαίδευση, εύγλωττα εγείρεται το ερώτημα της ορθής ή μη διάκρισης μεταξύ διαπολιτισμικών και κοινών σχολείων.
description: Modern society is characterized by diversity and heterogeneity, due to the large migration drift. Specifically, the Greek area, because of its geographical position, became an important center for receiving immigrants in each historical period. The aspects of the multicultural Greek society are directly noticed mainly in education area. Indeed, the need to support students from diverse cultural and linguistic backgrounds led the Greek state in the adoption of the principles and methods of Intercultural Education. Of course, the Intercultural Education had spread much earlier in the rest of Europe, especially with the creation of intercultural schools, while, early enough, there was talk of the organization and administration of intercultural schools. In particular, these intercultural schools are classified as “sensitive organizations”, cut off from the classical school assemblies. Furthermore, intense speech is carried out for the role of director of intercultural school unit and the applications of internal policies as far as the real and special needs of such a special school is concerned. In conclusion, following the formation of the student population in our country today and also the overall trends that are used in education eloquently raises the question of a right or not discrimination between intercultural and common schools.

description: This paper investigates the impacts of the different surface energy coefficients on the compound nucleus decay modes during heavy ion fusion reactions, with focus given to the superheavy nuclei (SHN) in the range of $Z=112-118$. The evaporation-residue (ER) cross sections were calculated for different surface asymmetric constants, $k_{s}$ and surface energy constants, $γ_{0}$. In these calculations, the di-nuclear system model and proximity potential, along with considering deformed nuclei, were employed. Comparing the experimental data and this theoretical approach, the best values of $k_{s}$ and $γ_{0}$ are $0.7546$ and $0.9180~\mathrm{MeV~fm^{-2}}$, respectively. Furthermore, this new model was used to investigate the probability of synthesis of experimentally unknown heavier systems with $Z=119$ and $120$. There exist five promising combinations to synthesize SHN with $Z=119$: a) ${^{249}}\mathrm{Cf}({^{45}}\mathrm{Sc},3n){^{291}}119$, b) ${^{249}}\mathrm{Cf}({^{45}}\mathrm{Sc},4n){^{290}}119$, c) ${^{247}}\mathrm {Bk}({^{50}}\mathrm{Ti},3n){^{294}}119$, d) ${^{254}}\mathrm{Es}({^{48}}\mathrm{Ca},3n){^{299}}119$, and e) ${^{254}}\mathrm{Es}({^{48}}\mathrm{Ca},4n){^{298}}119$. In addition, it is found that the best combinations to synthesize SHN with $Z=120$ are ${^{249}}\mathrm{Cf}({^{50}}\mathrm{Ti},3n){^{296}}120$, and ${^{251}}\mathrm{Cf}({^{50}}\mathrm{Ti},3n){^{298}}120$.

description: Self-organizing maps (SOM) are widely used for their topology preservation property: neighboring input vectors are quantified (or classified) either on the same location or on neighbor ones on a predefined grid. SOM are also widely used for their more classical vector quantization property. We show in this paper that using SOM instead of the more classical Simple Competitive Learning (SCL) algorithm drastically increases the speed of convergence of the vector quantization process. This fact is demonstrated through extensive simulations on artificial and real examples, with specific SOM (fixed and decreasing neighborhoods) and SCL algorithms.

description: n this paper we attempt to identify and describe the spontaneous concepts of preschool children concerning the formation of shadows and transform them through a didactical experimental proposal. The aim of this study is to mate children understand that the formation of shadows is the results of the obstruction begun our study by having the children in an individual interview situation, in order to identity their centrations, predictions and explanations of the phenomenon. We separated the children into two groups, a control group and an experimental. To the control group we showed a simple presentation of the didactical - experimental proposal with the experimental group. It is based on tasks that allow children to interact with the experimental material and create shadows, as well as to express themselves think and check the valid of their predictions. Furthermore, the didactical proposal included the presentation of the lorination of shadows through an analogous model.

description: PHANGS-HST is an ultraviolet-optical imaging survey of 38 spiral galaxies within ~20 Mpc. Combined with the PHANGS-ALMA, PHANGS-MUSE surveys and other multiwavelength data, the dataset will provide an unprecedented look into the connections between young stars, HII regions, and cold molecular gas in these nearby star-forming galaxies. Accurate distances are needed to transform measured observables into physical parameters (e.g., brightness to luminosity, angular to physical sizes of molecular clouds, star clusters and associations). PHANGS-HST has obtained parallel ACS imaging of the galaxy halos in the F606W and F814W bands. Where possible, we use these parallel fields to derive tip of the red giant branch (TRGB) distances to these galaxies. In this paper, we present TRGB distances for 11 galaxies from ~4 to ~15 Mpc, based on the first year of PHANGS-HST observations. Five of these represent the first published TRGB distance measurements (IC 5332, NGC 2835, NGC 4298, NGC 4321, and NGC 4328), and eight of which are the best available distances to these targets. We also provide a compilation of distances for the 118 galaxies in the full PHANGS sample, which have been adopted for the first PHANGS-ALMA public data release.

description: Our main result states that the hyperspace of convex compact subsets of a compact convex subset $X$ in a locally convex space is an absolute retract if and only if $X$ is an absolute retract of weight $\leω_1$. It is also proved that the hyperspace of convex compact subsets of the Tychonov cube $I^{ω_1}$ is homeomorphic to $I^{ω_1}$. An analogous result is also proved for the cone over $I^{ω_1}$. Our proofs are based on analysis of maps of hyperspaces of compact convex subsets, in particular, selection theorems for such maps are proved.

description: The genetic basis of complex diseases involves alterations on multiple genes. Unravelling the interplay between these genetic factors is key to the discovery of new biomarkers and treatments. In 2014, we introduced GUILDify, a web server that searches for genes associated to diseases, finds novel disease-genes applying various network-based prioritisation algorithms and proposes candidate drugs. Here, we present GUILDify v2.0, a major update and improvement of the original method, where we have included protein interaction data for seven species and 22 human tissues and incorporated the disease-gene associations from DisGeNET. To infer potential disease relationships associated with multi-morbidities, we introduced a novel feature for estimating the genetic and functional overlap of two diseases using the top-ranking genes and the associated enrichment of biological functions and pathways (as defined by GO and Reactome). The analysis of this overlap helps to identify the mechanistic role of genes and protein-protein interactions in comorbidities. Finally, we provided an R package, guildifyR, to facilitate programmatic access to GUILDify v2.0 (http://sbi.upf.edu/guildify2). The research has been recently published in Journal of Molecular Biology (doi: 10.1016/j.jmb.2019.02.027).

description: The observed time delays between photons with different circular polarizations from an astrophysical object provide a new, interesting way of testing the Einstein Equivalence Principle (EEP). In this paper, we constrain the EEP by considering both Shapiro time delay and Faraday rotation effects. We continue to search for astronomical sources that are suitable for testing the EEP accuracy, and obtain 60 extragalactic radio sources with multi-wavelength polarization angles in three different radio bands (20, 8.6, and 4.8 GHz) and 29 brightest stars within our own Milky Way galaxy with multi-colour linear polarimetric data in five optical bands ($UBVRI$). We apply the Metropolis-Hastings Markov Chain to simulate the fit parameters. The final results show that the values of the parameterized post-Newtonian parameter $γ$ discrepancy ($Δγ_{p}$) are constrained to be in the range of $10^{-26}-10^{-23}$ for 60 radio sources and in the range of $10^{-23}-10^{-20}$ for 29 optical polarization stars. Compared to previous EEP tests that based on the single polarization measurement in the gamma-ray band, our results have profound superiority that nearly a few tens of astrophysical sources with multi-wavelength polarization observations commonly in the optical and radio bands are available. It ensures that these sources can give more significantly robust bounds on the EEP. Although the presented method is straightforward, the resulting constraints on the EEP should be taken as upper limits as other more complex astrophysical effects affecting a polarization rotation are hardly considered.

description: This paper presents the development of a complete CAD-compatible framework for structural shape optimization in 3D. The boundaries of the domain are described using NURBS while the interior is discretized with Bézier tetrahedra. The tetrahedral mesh is obtained from the mesh generator software Gmsh. A methodology to reconstruct the NURBS surfaces from the triangular faces of the boundary mesh is presented. The description of the boundary is used for the computation of the analytical sensitivities with respect to the control points employed in surface design. Further, the mesh is updated at each iteration of the structural optimization process by a pseudo-elastic moving mesh method. In this procedure, the existing mesh is deformed to match the updated surface and therefore reduces the need for remeshing. Numerical examples are presented to test the performance of the proposed method. The use of the movable mesh technique results in a considerable decrease in the computational effort for the numerical examples.

description: We have developed and tested an antireflection (AR) coating method for silicon lenses at cryogenic temperatures and millimeter wavelengths. Our particular application is a measurement of the cosmic microwave background. The coating consists of machined pieces of Cirlex glued to the silicon. The measured reflection from an AR coated flat piece is less than 1.5% at the design wavelength. The coating has been applied to flats and lenses and has survived multiple thermal cycles from 300 to 4 K. We present the manufacturing method, the material properties, the tests performed, and estimates of the loss that can be achieved in practical lenses.

description: Modern biomedical, behavioral and psychological inference about cause-effect relationships respects an ergodic assumption, that is, that mean response of representative samples allow predictions about individual members of those samples. Recent empirical evidence in all of the same fields indicates systematic violations of the ergodic assumption. Indeed, violation of ergodicity in biomedical, behavioral and psychological causes is precisely the inspiration behind our research inquiry. Here, we review the long term costs to scientific progress in these domains and a practical way forward. Specifically, we advocate the use of statistical measures that can themselves encode the degree and type of non-ergodicity in measurements. Taking such steps will lead to a paradigm shift, allowing researchers to investigate the nonstationary, far-from-equilibrium processes that characterize the creativity and emergence of biological and psychological behavior.

description: Rationale and Coverage: United National Development Programme (UNDP) believes that in order to achieve the global Sustainable Development Goals (SDGs), it is vital to mobilise and leverage the wide range of public-private shared resource contributions. This enables integration towards positive, inclusive and sustainable development of the nations by aligning these investments with the 17 SDGs . South Asian countries have a significant impact on the global achievement of the SDGs. Thus, it is pertinent to study the effect of Partnership for Goals on the economic performance and development of the South Asian countries where wide range of country specific challenges hamper the social, economic and environmental growth. Objectives: This paper attempts to study the cause and effect of the indicators of Sustainable Development Goals for Global Partnership on the economic development of South Asian Countries. Methodology: The study is quantitative in nature. The empirical analysis on the World Bank dataset of select SDG 17 indicators and economic development drivers are performed using panel data regression for the period 2010 - 2018. Data is collected from various websites, reports and databases of UNDP, World Bank, IMF and Government websites of the South Asian Countries. Significance: This paper also aims to understand the stimulus provided by the various SDG indicators on the economic performance of South Asian Nations through mobilisation and optimisation of the resources pooled through the collaborative partnership financing activities.

description: Based on computer simulations and theoretical analysis, a new dynamic state is found in inductively coupled intrinsic Josephson junctions in the absence of an external magnetic field. In this state, the plasma oscillation is uniform along the c axis and there are $(2m+1)π$ phase kinks, with $m$ being an integer, periodic and thus non-uniform in the $c$ direction. In the IV characteristics, the state manifests itself as current steps occurring at all cavity modes. Inside the current steps, the plasma oscillation becomes strong, which generates several harmonics in frequency spectra at a given voltage. The recent experiments on terahertz radiations from the mesa of a BSCCO single crystal can be explained in terms of this state.

description: A gravitational wave event, S190510g, which was classified as a binary-neutron-star coalescence at the time of preliminary alert, was detected by LIGO/Virgo collaboration on May 10, 2019. At 1.7 hours after the issue of its preliminary alert, we started a target-of-opportunity imaging observation in Y-band to search for its optical counterpart using the Hyper Suprime-Cam (HSC) on the Subaru Telescope. The observation covers a 118.8 deg$^2$ sky area corresponding to 11.6% confidence in the localization skymap released in the preliminary alert and 1.2% in the updated skymap. We divided the observed area into two fields based on the availability of HSC reference images. For the fields with the HSC reference images, we applied an image subtraction technique; for the fields without the HSC reference images, we sought individual HSC images by matching a catalog of observed objects with the PS1 catalog. The search depth is 22.28 mag in the former method and the limit of search depth is 21.3 mag in the latter method. Subsequently, we performed visual inspection and obtained 83 candidates using the former method and 50 candidates using the latter method. Since we have only the 1-day photometric data, we evaluated probability to be located inside the 3D skymap by estimating their distances with photometry of associated extended objects. We found three candidates are likely located inside the 3D skymap and concluded they could be an counterpart of S190510g, while most of 133 candidates were likely to be supernovae because the number density of candidates was consistent with the expected number of supernova detections. By comparing our observational depth with a light curve model of such a kilonova reproducing AT2017gfo, we show that early-deep observations with the Subaru/HSC can capture the rising phase of blue component of kilonova at the estimated distance of S190510g (~230 Mpc).

description: Using archival X-ray data, we find that the catalog location of the X-ray binary Scutum X-1 (Sct X-1) is incorrect, and that the correct location is that of the X-ray source AX J183528-0737, which is 15' to the west. Our identification is made on the basis of the 112-s pulse period for this object detected in an XMM-Newton observation, as well as spatial coincidence between AX J183528-0737 and previous X-ray observations. Based on the XMM-Newton data and archival RXTE data, we confirm secular spin-down over 17 years with period derivative Pdot~3.9e-9 s/s, but do not detect a previously reported X-ray iron fluorescence line. We identify a bright (Ks=6.55), red (J-Ks=5.51), optical and infrared counterpart to AX J183528-0737 from 2MASS, a number of mid-IR surveys, and deep optical observations, which we use to constrain the extinction to and distance of Sct X-1. From these data, as well as limited near-IR spectroscopy, we conclude that Sct X-1 is most likely a binary system comprised of a late-type giant or supergiant and a neutron star.

description: The global phase behavior of the lattice restricted primitive model with nearest neighbor exclusion has been studied by grand canonical Monte Carlo simulations. The phase diagram is dominated by a fluid (or charge-disordered solid) to charge-ordered solid transition that terminates at the maximum density, $ρ^*_{max}=\sqrt2$ and reduced temperature $T^*\approx0.29$. At that point, there is a first-order phase transition between two phases of the same density, one charge-ordered and the other charge-disordered. The liquid-vapor transition for the model is metastable, lying entirely within the fluid-solid phase envelope.

description: We present results from our X-ray analysis of the first systematic search for triple AGN in nearby (z<0.077) triple galaxy mergers. We analyze archival Chandra observations of 7 triple galaxy mergers with BAYMAX (Bayesian Analysis of Multiple AGN in X-rays), fitting each observation with single, dual, and triple X-ray point source models. In doing so, we conclude that 1 triple merger has one X-ray point source (SDSS J0858+1822, although it's unlikely to be an AGN); 5 triple mergers are likely composed of two X-ray point sources (NGC 3341, SDSS J1027+1749, SDSS J1631+2352, SDSS J1708+2153, and SDSS J2356$-$1016); and one system is composed of three X-ray point sources (SDSS J0849+1114). By fitting the individual X-ray spectra of each point source, we analyze the 2-7 keV luminosities as well as the levels of obscuration associated with each potential AGN. We find that 4/5 dual X-ray point source systems have primary and secondary point sources with bright X-ray luminosities (L_2-7 kev >10^40 erg s^-1), possibly associated with 4 new undetected dual AGN. The dual and triple point source systems are found to have physical separations between 3-9 kpc and flux ratios between 2x10^-3 - 0.84. A multi-wavelength analysis to determine the origin of the X-ray point sources discovered in this work is presented in our companion paper (Foord et al. 2020c).

description: Nous avons cherché à étudier 1' imaginaire de 1' enfant d' âge préscolaire, à terter sa capacité imaginaire. Notre but de recherche a été de prendre pour objet d' étude les histoires que les enfants ont créées inventées, ayant comme point de départ certains événements des contes, déjà cités par nous-même, afin de découvrir comment leur imaginaire se structure, ainsi que le schéma de sa construction. C est donc la relation privilégiée de I' imaginaire et du langage que nous avons examiné chez 1* enfant, puisque nous avons testé sa capacité imaginaire à partir de ses productions langagières. D' après nos résultais : I. L'imaginaire de 1' enfant se structure de façon narrative, c’est à dire qu’il est structuré de grandes structures, de schémas narratifs différents. L’originalité des dénouements et des rôles arsumés par les personnages qui participent à 1' action, 1' enrichissement ou le prolongement de l histoire d un récit intermédiaire ou supplémentaire, sont des explications de la créativité dans les récils inventés par les enfants. Ainsi, la créativité verbale apparaît dans les II. La structure réalisée est figurative, c’est à dire qu’il y a «mille et une» façons différentes effectuer, d’exprimer le même schéma narratif. La créativité verbale apparaît dans les figures. C est donc au point de 1' articulation du programme narratif et de l espace figuratif ou il se déploie, que l enfant trouve l occasion de manifester son individualité.

description: Prediction of phenotypes from organisms’ genotypes is one of the major challenges in biomedical science. Large amounts of clinical and genetic data make it nowadays approachable computationally. We focus on the nuclear problem: predicting phenotypic impact of individual genetic variants. Numerous lines of evidence suggest that there is a correlation between the variant-carrying gene’s identity and certain phenotypes, introducing a statistical bias. It can artificially inflate performance of methods in a setting when mutations, but not genes are randomly split into the training and test sets. Methods trained in such a way are likely to misclassify benign variants in pathogenicity-prone genes and to fail when predicting the impact of variants in genes not seen in the training.
We present a novel random forest-based machine learning method that employs features related to protein evolution and their three-dimensional structures. By applying it to deep mutational scan data and clinically annotated mutations from ClinVar, we demonstrate that including structure-related features and excluding features that may introduce protein bias, such as protein length or tendency to form homooligomeric complexes, improves the performance in a fair setting when genes as a whole, and not individual mutations, are split into the training and test sets.

description: In this note we study the adiabatic perturbation spectrum of N-flation with power law potential. We show that the scalar spectrum of N-flation is generally redder than that of its corresponding single field. The result obtained for that with unequal massive fields is consistent with the recent numerical investigation of Kim and Liddle.

description: Understanding the geometry and kinematics of the broad line region (BLR) of active galactic nuclei (AGN) is important to estimate black hole masses in AGN and study the accretion process. The technique of reverberation mapping (RM) has provided estimates of BLR size for more than 100 AGN now, however, the structure of the BLR has been studied for only a handful number of objects. Towards this, we investigated the geometry of the BLR for a large sample of 57 AGN using archival RM data. We performed systematic modeling of the continuum and emission line light curves using a Markov Chain Monte Carlo method based on Bayesian statistics implemented in PBMAP (Parallel Bayesian code for reverberation-MAPping data) code to constrain BLR geometrical parameters and recover velocity integrated transfer function. We found that the recovered transfer functions have various shapes such as single-peaked, double-peaked and top-hat suggesting that AGN have very different BLR geometries. Our model lags are in general consistent with that estimated using the conventional cross-correlation methods. The BLR sizes obtained from our modeling approach is related to the luminosity with a slope of 0.583 (+/-) 0.026 and 0.471 (+/-) 0.084 based on Hβ and Hα lines, respectively. We found a non-linear response of emission line fluxes to the ionizing optical continuum for 93\% objects. The estimated virial factors for the AGN studied in this work range from 0.79 to 4.94 having a mean at 1.78 (+/-) 1.77 consistent with the values found in the literature.

description: Because the staggered fermion determinant is complex at nonzero mu, taking its fourth root leads to phase ambiguities. These unphysical effects cause the measure to become discontinuous; the problem becomes acute when Re mu exceeds approximately half the pion mass (when T>0 this rough bound probably moves towards larger mu). We show how to overcome the problem, but only very close to the continuum limit. This regime may be beyond reach with current resources.

description: Quadruped robots have strong adaptability to extreme environments but may also experience faults. Once these faults occur, robots must be repaired before returning to the task, reducing their practical feasibility. One prevalent concern among these faults is actuator degradation, stemming from factors like device aging or unexpected operational events. Traditionally, addressing this problem has relied heavily on intricate fault-tolerant design, which demands deep domain expertise from developers and lacks generalizability. Learning-based approaches offer effective ways to mitigate these limitations, but a research gap exists in effectively deploying such methods on real-world quadruped robots. This paper introduces a pioneering teacher-student framework rooted in reinforcement learning, named Actuator Degradation Adaptation Transformer (ADAPT), aimed at addressing this research gap. This framework produces a unified control strategy, enabling the robot to sustain its locomotion and perform tasks despite sudden joint actuator faults, relying exclusively on its internal sensors. Empirical evaluations on the Unitree A1 platform validate the deployability and effectiveness of Adapt on real-world quadruped robots, and affirm the robustness and practicality of our approach.

description: We show that Floquet chiral topological superconductivity arises naturally in Josephson junctions made of magnetic topological insulator-superconductor sandwich structures. The Josephson phase modulation associated with an applied bias voltage across the junction drives the system into the anomalous Floquet chiral topological superconductor hosting chiral Majorana edge modes in the quasienergy spectrum, with the bulk Floquet bands carrying zero Chern numbers. The bias voltage acts as a tuning parameter enabling novel dynamical topological quantum phase transitions driving the system into a myriad of exotic Majorana-carrying Floquet topological superconducting phases. Our theory establishes a new paradigm for realizing Floquet chiral topological superconductivity in solid-state systems, which should be experimentally directly accessible.

description: Experimental investigations of plastic flow have demonstrated temporal intermittency as deformation proceeds in a series of intermittent bursts with scale-free size distribution. In the present investigation, a corresponding spatial intermittency is demonstrated for plastic flow of KCl single crystals. Deformation bursts lead to large surface steps with a height distribution that is consistent with the distribution of strain increments in deformation of micro-columns, and the energy distribution of acoustic emission bursts observed in deformation of macroscopic single crystal samples of a wide class of materials.

description: Στη δημόσια εκπαίδευση, η ποιότητα εκμάθησης υπόκειται σταθερά σε αξιολόγηση.

Αυτά τα συμπεράσματα, αυθεντικά σε επιστημονικό πλαίσιο, μπορούνε ομοίως, να αποτελέσουνε πολύτιμες πηγές για την προσαρμογή των προγραμμάτων εκμάθησης, αρχικής και συνεχούς εκπαίδευσης.
description: In public education, the teaching quality is subject to constant review. Evaluation practices perform various functions (prognostic assessment, diagnostics, final, evaluation of certification of language skills) that are applicable to specific phases of learning (initial assessment, middle, final) and often reinforce the existing character of the institutions (school report / progress, final exams, language certification). A relatively new term in the evaluation of education is that of «impact». It is the practice, the influence exerted by the rating practices in teaching practices / learning: new types of activities, new pedagogical approaches, new teaching models, new trainings trainers etc. The findings of such a study would allow the consolidation of new knowledge, derived from field observation rather than theoretical interactions between two acts - learning and evaluation- which compose the educational act. These conclusions, original scientific framework, may similarly be valuable sources for the adjustment of learning programs, initial and continuing education.
