description: El hecho de abrir supermercados sin dependientes humanos no es quizá lo más llamativo de la noticia. Lo es también que la tecnología desarrollada por Amazon pueda reportar suntuosas ganancias al venderla a otras empresas que deseen aplicar en sus tiendas tan innovadora aplicación, y que pasarán a ser meros subsidiarios de este nuevo señor feudal corporativo. Amazon, en línea con otros gigantes tecnológicos, continúa esforzándose en robotizar la mayoría de sus operaciones y, por ende, las nuestras son cada vez más ‘democracias robotizadas’. La finalidad no es otra que eliminar mano de obra en todo lo que sea posible. Además, ahora sabemos que también quiere vender la tecnología y hacerse con un mercado de rentabilidad incalculable.

description: The pionic contribution to the g-2 of the muon involves a certain integral over the the modulus squared of F_π(t), the pion electromagnetic form factor. We extend techniques that use cut-plane analyticity properties of F_π(t) in order to account for present day estimates of the pionic contribution and experimental information at a finite number of points in the space-like region. Using data from several experiments over a large kinematic range for |t|, we find bounds on the expansion coefficients of F_π(t), sub-leading to the charge radius. The value of one of these coefficients in chiral perturbation theory respects these bounds. Furthermore, we present a sensitivity analysis to the inputs. A brief comparison with results in the literature that use observables other than the g-2 and timelike data is presented.

description: Prominences in the solar atmosphere represent an intriguing and delicate balance of forces and thermodynamics in an evolving magnetic topology. How this relatively cool material comes to reside at coronal heights, and what drives its evolution prior to, during, and after its appearance remains an area full of open questions. We deliberately focus on the levitation-condensation scenario, where a coronal flux rope forms and eventually demonstrates in-situ condensations, revisiting it at extreme resolutions down to order 6 km in scale. We perform grid-adaptive numerical simulations in a 2.5D translationally invariant setup, where we can study the distribution of all metrics involved in advanced magnetohydrodynamic stability theory for nested flux rope equilibria. We quantify in particular Convective Continuum Instability (CCI), Thermal Instability (TI), baroclinicity, and mass-slipping metrics within a series of numerical simulations of prominences formed via levitation-condensation. Overall, we find that the formation and evolution of prominence condensations happens in a clearly defined sequence regardless of resolution or background field strength between 3 and 10 Gauss. The CCI governs the slow evolution of plasma prior to the formation of distinct condensations found to be driven by the TI. Evolution of the condensations towards the topological dips of the magnetic flux rope is a consequence of these condensations forming initially outside of pressure balance with their surroundings. From the baroclinicity distributions, smaller-scale rotational motions are inferred within forming and evolving condensations. Upon the complete condensation of a prominence `monolith', the slow descent of this plasma towards lower heights appears consistent with the mass-slippage mechanism driven by episodes of both local current diffusion and magnetic reconnection.

It is an improvement on a method previously devised by the authors, and provides a correct description of the photon sphere already to first order. We also propose an alternative approach that provides general simpler formulas, although with larger errors. We apply our technique to different metrics and verify that the error is at most $0.5 %$ for {\sl all} regimes. We show that our approximation is more accurate than others proposed earlier.

description: We report on the X-ray aperiodic timing analysis of two accreting millisecond pulsars: XTE J1807-294 and IGR J00291+5934. On the one hand, we discovered in XTE J1807-294 seven pairs of simultaneous kilohertz quasi-periodic oscillations (kHz QPOs) separated in frequency by nearly the spin frequency of the neutron star. This confirms the suspected dichotomy in the frequency separation of kHz QPOs: sometimes once and sometimes half the spin frequency. On the other hand, we found an extreme behavior in the power spectra of IGR J00291+5934: very strong variability at very low frequencies. Namely, the fractional amplitude of the variability was ~50%, the highest value found so far in a neutron star system.

description: Artificial intelligence has made great strides since the deep learning revolution, but AI systems still struggle to extrapolate outside of their training data and adapt to new situations. For inspiration we look to the domain of science, where scientists have been able to develop theories which show remarkable ability to extrapolate and sometimes predict the existence of phenomena which have never been observed before. According to David Deutsch, this type of extrapolation, which he calls "reach", is due to scientific theories being hard to vary. In this work we investigate Deutsch's hard-to-vary principle and how it relates to more formalized principles in deep learning such as the bias-variance trade-off and Occam's razor. We distinguish internal variability, how much a model/theory can be varied internally while still yielding the same predictions, with external variability, which is how much a model must be varied to accurately predict new, out-of-distribution data. We discuss how to measure internal variability using the size of the Rashomon set and how to measure external variability using Kolmogorov complexity. We explore what role hard-to-vary explanations play in intelligence by looking at the human brain and distinguish two learning systems in the brain. The first system operates similar to deep learning and likely underlies most of perception and motor control while the second is a more creative system capable of generating hard-to-vary explanations of the world. We argue that figuring out how replicate this second system, which is capable of generating hard-to-vary explanations, is a key challenge which needs to be solved in order to realize artificial general intelligence. We make contact with the framework of Popperian epistemology which rejects induction and asserts that knowledge generation is an evolutionary process which proceeds through conjecture and refutation.

description: We perform a quantitative analysis of the cooling dynamics of three-level atomic systems interacting with two distinct lasers. Employing sparse-matrix techniques, we find numerical solutions to the fully quantized master equation in steady state. Our method allows straightforward determination of laser-cooling temperatures without the ambiguity often accompanied by semiclassical calculations, and more quickly than non-sparse techniques. Our calculations allow us to develop an understanding of the regimes of cooling, as well as a qualitative picture of the mechanism, related to the phenomenon of electromagnetically induced transparency. Effects of the induced asymmetric Fano-type lineshapes affect the detunings required for optimum cooling, as well as the predicted minimum temperatures which can be lower than the Doppler limit for either transition.

Accretion Rates and Beaming in Ultraluminous X-ray Sources

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: I show that extreme beaming factors $b$ are not needed to explain ULXs as stellar--mass binaries. For neutron star accretors one typically requires $b \sim 0.13$, and for black holes almost no beaming ($b \sim 0.8$). The main reason for the high apparent luminosity is the logarithmic increase in the limiting luminosity for super--Eddington accretion. The required accretion rates are explicable in terms of thermal--timescale mass transfer from donor stars of mass $6 - 10\msun$, or possibly transient outbursts. Beaming factors $\la 0.1$ would be needed to explain luminosities significantly above $10^{40}L_{40}$ erg s$^{-1}$, but these requirements are relaxed somewhat if the accreting matter has low hydrogen content.

description: The recent advances in artificial intelligence namely in machine learning and deep learning, have boosted the performance of intelligent systems in several ways. This gave rise to human expectations, but also created the need for a deeper understanding of how intelligent systems think and decide. The concept of explainability appeared, in the extent of explaining the internal system mechanics in human terms. Recommendation systems are intelligent systems that support human decision making, and as such, they have to be explainable in order to increase user trust and improve the acceptance of recommendations. In this work, we focus on a context-aware recommendation system for energy efficiency and develop a mechanism for explainable and persuasive recommendations, which are personalized to user preferences and habits. The persuasive facts either emphasize on the economical saving prospects (Econ) or on a positive ecological impact (Eco) and explanations provide the reason for recommending an energy saving action. Based on a study conducted using a Telegram bot, different scenarios have been validated with actual data and human feedback. Current results show a total increase of 19\% on the recommendation acceptance ratio when both economical and ecological persuasive facts are employed. This revolutionary approach on recommendation systems, demonstrates how intelligent recommendations can effectively encourage energy saving behavior.

description: We reconsider QED radiative corrections (RC) to the $π^{0}\to e^{+}e^{-}$ decay width. One kind of RC investigated earlier has a renormalization group origin and can be associated with the final state interaction of electron and positron. It determines the distribution of lepton pair invariant masses in the whole kinematic region. The other type of RC has a double-logarithmic character and is related to almost on-mass-shell behavior of the lepton form factors. The total effect of RC for the $π^{0}\to e^{+}e^{-}$ decay is estimated to be 3.2% and for the decay $η\to e^{+}e^{-}$ is 4.3%.

description: A brief review is given of dark matter in SUGRA, strings and branes. For SUGRA models the implications of Yukawa coupling unification on dark matter are discussed in the light of $g-2$ and $b\to sγ$ constraints. A brief discussion is given of the dark matter in orbifold string compactifications under constraints of modular invariance and radiative breaking of the electroweak symmetry. Finally a new candidate for dark matter - an extra-weakly interacting massive particle or an XWIMP- is discussed. Such dark matter can arise in a wide class of models, including the Stueckelberg extensions of MSSM, in U(1) extensions of MSSM with off diagonal kinetic energy, and possibly in a wider class of models which may have a string/D-brane origin. Satisfaction of the relic density of XWIMPs consistent with WMAP is also discussed.

We apply a scalar-vector-tensor decomposition to two tensor fields by virtue of 3-dimensional rotation-invariance of Minkowski spacetime and classify theories with seven degrees of freedom based on the Hamiltonian analysis. We find two new theories, which cannot be mapped from the linearized Hassan-Rosen bigravity. In these theories, the new mass interactions can be allowed thanks to the transverse diffeomorphism invariance of action.

description: The operators that break supersymmetry can be holomorphic or non-holomorphic in structure. The latter do not pose any problem for gauge hierarchy and are soft provided that the particle spectrum does not contain any gauge singlets. In minimal supersymmetric model (MSSM) we discuss the impact of non-holomorphic soft-breaking terms on the Higgs sector. We find that non-holomorphic operators can cause significant changes as are best exhibited by the correlation between the masses of the charginos and Higgs bosons.

description: In this article, visible-to-ultraviolet photon upconversion (UV-UC) by triplet-triplet annihilation in the emission range shorter than 340 nm, which is previously unexplored, is presented and the relevant physicochemical characteristics are elucidated. Investigations were carried out in several deaerated solvents using acridone and naphthalene derivatives as a sensitizer and emitter, respectively. Both upconversion quantum efficiency and sample photostability under continuous photoirradiation strongly depended on the solvent. The former dependence is governed by the solvent polarity, which affects the triplet energy level matching between the sensitizer and emitter because of the solvatochromism of the sensitizer. To elucidate the latter, first we investigated the photodegradation of samples without the emitter, which revealed that the sensitizer degradation rate is correlated with the difference between the frontier orbital energy levels of the sensitizer and solvent. Inclusion of the emitter effectively suppressed the degradation of the sensitizer, which is ascribed to fast quenching of the triplet sensitizer by the emitter and justifies the use of ketonic sensitizers for UV-UC in solvents. A theoretical model was developed to acquire insight into the observed temporal decays of the upconverted emission intensity under continuous photoirradiation. The theoretical curves generated by this model fitted the experimental decay curves well, which allowed the reaction rate between the emitter and solvent to be obtained. This rate was also correlated with difference between the frontier orbital energy levels of the emitter and solvent. Finally, based on the acquired findings, general design guidelines for developing UV-UC samples were proposed.

description: Life expectancy for humans averaged around 35 years until the end of the 19th century. Since then, it has more than doubled, especially in Mediterranean countries where it now reaches almost 85 years. According to the World Economic Forum, in 2040 Spain would be the country with the highest life expectancy in the world (85.8 years) and Italy would rank fifth (84.5 years). The impact of the Covid-19 pandemic will affect these predictions as both countries have had an excess of deaths during 2020. However, both countries exemplify the increase of life expectancy during the last 120 years. The main factor promoting this increase in life expectancy is the development of antibiotics and vaccines that resulted in a marked decrease in bacterial and viral diseases that plagued our species throughout history. The current leading causes of death in the Western world, and especially in Europe, are dominated by coronary heart disease and cancer-related conditions. That is, diseases related to old age and poor eating habits in advanced societies. Nevertheless, infectious diseases are far from being eliminated as a threat, since bacteria and viruses continue to evolve and circumvent both natural and artificial barriers to infection.

description: We present a new algorithm for estimating the Point Spread Function (PSF) in wide-field astronomical images with extreme source crowding. Robust and accurate PSF estimation in crowded astronomical images dramatically improves the fidelity of astrometric and photometric measurements extracted from wide-field sky monitoring imagery. Our radically new approach utilizes convolutional sparse representations to model the continuous functions involved in the image formation. This approach avoids the need to detect and precisely localize individual point sources that is shared by existing methods. In experiments involving simulated astronomical imagery, it significantly outperforms the recent alternative method with which it is compared.

description: This thesis explores the concepts Mental Arithmetic and Computational Estimation in order to show their significance in the didactics of Mathematics.Moreover, it introduces specific strategies of computational estimation that foreing investigators have previously suggested, which help pupils develop abilities for computational estimation and mental arithmetic. After the theoritical part follows a research that the writer carried out in a classs of 17 pupils in the 4th grade of primary school. The aims of the research are to introduce the pupils in the previous concepts, to show them their significance to every day life, and to teach them specific strategies of computational estimation. Thereafter, the pupils are trained in these strategies adn the writer evaluates their performance at problems of computational estimation that involve addition and multiplication of integer and decimal numbers. The analysis of the data follows, as well as the final conclusions that arise from the research
Phase-Space Volume of Regions of Trapped Motion: Multiple Ring Components and Arcs

description: The phase--space volume of regions of regular or trapped motion, for bounded or scattering systems with two degrees of freedom respectively, displays universal properties. In particular, sudden reductions in the phase-space volume or gaps are observed at specific values of the parameter which tunes the dynamics; these locations are approximated by the stability resonances. The latter are defined by a resonant condition on the stability exponents of a central linearly stable periodic orbit. We show that, for more than two degrees of freedom, these resonances can be excited opening up gaps, which effectively separate and reduce the regions of trapped motion in phase space. Using the scattering approach to narrow rings and a billiard system as example, we demonstrate that this mechanism yields rings with two or more components. Arcs are also obtained, specifically when an additional (mean-motion) resonance condition is met. We obtain a complete representation of the phase-space volume occupied by the regions of trapped motion.

description: The transportation system is rapidly evolving with new connected and automated vehicle (CAV) technologies that integrate CAVs with other vehicles and roadside infrastructure in a cyberphysical system (CPS). Through connectivity, CAVs affect their environments and vice versa, increasing the size of the cyberattack surface and the risk of exploitation of security vulnerabilities by malicious actors. Thus, greater understanding of potential CAV-CPS cyberattacks and of ways to prevent them is a high priority. In this article we describe CAV-CPS cyberattack surfaces and security vulnerabilities, and outline potential cyberattack detection and mitigation strategies. We examine emerging technologies - artificial intelligence, software-defined networks, network function virtualization, edge computing, information-centric and virtual dispersive networking, fifth generation (5G) cellular networks, blockchain technology, and quantum and postquantum cryptography - as potential solutions aiding in securing CAVs and transportation infrastructure against existing and future cyberattacks.

description: Operating systems have historically had to manage only a single type of memory device. The imminent availability of heterogeneous memory devices based on emerging memory technologies confronts the classic single memory model and opens a new spectrum of possibilities for memory management. Transparent data movement between different memory devices based on access patterns of applications is a desired feature to make optimal use of such devices and to hide the complexity of memory management to the end-user. However, capturing memory access patterns of an application at runtime comes at a cost, which is particularly challenging for large scale parallel applications that may be sensitive to system noise. In this work, we focus on the access pattern profiling phase prior to the actual memory relocation. We study the feasibility of using Intel's Processor Event-Based Sampling (PEBS) feature to record memory accesses by sampling at runtime and study the overhead at scale. We have implemented a custom PEBS driver in the IHK/McKernel lightweight multi-kernel operating system, one of whose advantages is minimal system interference due to the lightweight kernel's simple design compared to other OS kernels such as Linux. We present the PEBS overhead of a set of scientific applications and show the access patterns identified in noise-sensitive HPC applications. Our results show that clear access patterns can be captured with a 10% overhead in the worst-case and 1% in the best case when running on up to 128k CPU cores (2,048 Intel Xeon Phi Knights Landing nodes). We conclude that online memory access profiling using PEBS at large scale is promising for memory management in heterogeneous memory environments.

The Ghost-Box-Ball System: A Unified Perspective on Soliton Cellular Automata, the RSK Algorithm and Phase Shifts

description: In this paper, we introduce the ghost-box-ball system, which is an extended version of the classical soliton cellular automaton. It is initially motivated as a mechanism for making precise a connection between the Schensted insertion (of the Robinson-Schensted-Knuth correspondence) and the dynamical process of the box-ball system. In addition to this motivation, we explore generalisations of classical notions of the box-ball system, including the solitonic phenomenon, the asymptotic sorting property, and the invariant shape construction. We analyse the ghost-box-ball system beyond its initial relevance to the Robinson-Schensted-Knuth correspondence, unpacking its relationship to its underlying dynamical evolution on a coordinatisation and using a mechanism for augmenting a regular box-ball configuration to study the classical ultradiscrete phase shift phenomenon.

description: Η παρούσα πτυχιακή εργασία μελετάει τα πεδία της διαχείρισης έργων, της διαχείρισης έργων λογισμικού και το πεδίο των οντολογιών με τελικό στόχο τη δημιουργία μιας οντολογίας για το πεδίο της διαχείρισης έργων λογισμικού. Ο στόχος λοιπόν είναι διπλός. Αρχικά παρατίθεται μια βιβλιογραφική ανασκόπηση των ανωτέρω πεδίων και ακολουθεί η πρακτική εφαρμογή, που είναι η δημιουργία της οντολογίας. Η πτυχιακή εργασία τελειώνει με τα συμπεράσματα της παραπάνω μελέτης. Όσον αφορά τη βιβλιογραφική ανασκόπηση, η μελέτη των πεδίων γίνεται με στόχο την αναφορά στοιχείων που θα βοηθήσουν στην ανάπτυξη της οντολογίας. Δεν πρόκειται λοιπόν για μια γενική μελέτη του κάθε πεδίου. Για παράδειγμα, επειδή στην οντολογία, για το πεδίο της διαχείρισης έργων θα χρησιμοποιηθεί και η βάση γνώσης PMBOK, στην βιβλιογραφική ανασκόπηση γίνεται μια προσπάθεια να δοθούν, με όσον το δυνατόν πιο συνοπτικό τρόπο, όλοι οι βασικοί όροι που εμφανίζονται στη συγκεκριμένη βάση γνώσης. Όσον αφορά τη δημιουργία της οντολογίας της διαχείρισης έργων λογισμικού, έγινε μια προσπάθεια να ενωθούν τα πεδία της διαχείρισης έργων και της τεχνολογίας λογισμικού. Η οντολογία στηρίχθηκε σε διεθνώς αναγνωρισμένες βάσεις γνώσης όπως είναι η PMBOK και άλλες, ενώ τεκμηριώθηκε με βάση παλαιότερες προσπάθειες για τη δημιουργία οντολογιών, οι οποίες αναφέρονται στην ενότητα «Οντολογίες, Διαχείριση Έργων Λογισμικού & Τεχνολογία Λογισμικού». Επιπρόσθετα, στόχος της οντολογίας δεν είναι η πλήρης και αναλυτική περιγραφή όλων των όρων που υπάρχουν στο συγκεκριμένο πεδίο, το οποίο θα απαιτούσε εκατοντάδες ή και χιλιάδες όρους. Αντίθετα, στόχος είναι η καταγραφή των πλέον βασικών όρων και οι σχέσεις μεταξύ τους. Η ανάπτυξη οντολογιών για την αναπαράσταση και τη μελέτη πεδίων παρουσιάζει ιδιαίτερο ενδιαφέρον και αποτελεί θέμα έρευνας για πολλούς ερευνητές. Οι οντολογίες μπορούν να παίξουν ένα σημαντικό ρόλο στον τομέα της διαχείρισης έργων λογισμικού, όπως και σε άλλες επιστήμες, καθώς παρέχουν μια πηγή καθορισμένων όρων, προσφέρουν μια κοινή κατανόηση του πεδίου και αποδίδουν σαφώς όλα τα κρυμμένα νοήματα όσον αφορά όλα τα αντικείμενα που περιλαμβάνονται στο συγκεκριμένο πεδίο γνώσης.

description: In this paper we present results of the lowest eigenvalues of random Hamiltonians for both fermion and boson systems. We show that an empirical formula of evaluating the lowest eigenvalues of random Hamiltonians in terms of energy centroids and widths of eigenvalues are applicable to many different systems (except for $d$ boson systems). We improve the accuracy of the formula by adding moments higher than two. We suggest another new formula to evaluate the lowest eigenvalues for random matrices with large dimensions (20-5000). These empirical formulas are shown to be applicable not only to the evaluation of the lowest energy but also to the evaluation of excited energies of systems under random two-body interactions.
