description: The geometric mean is shown to be an appropriate statistic for the scale of a heavy-tailed coupled Gaussian distribution or equivalently the Student's t distribution. The coupled Gaussian is a member of a family of distributions parameterized by the nonlinear statistical coupling which is the reciprocal of the degree of freedom and is proportional to fluctuations in the inverse scale of the Gaussian. Existing estimators of the scale of the coupled Gaussian have relied on estimates of the full distribution, and they suffer from problems related to outliers in heavy-tailed distributions. In this paper, the scale of a coupled Gaussian is proven to be equal to the product of the generalized mean and the square root of the coupling. From our numerical computations of the scales of coupled Gaussians using the generalized mean of random samples, it is indicated that only samples from a Cauchy distribution (with coupling parameter one) form an unbiased estimate with diminishing variance for large samples. Nevertheless, we also prove that the scale is a function of the geometric mean, the coupling term and a harmonic number. Numerical experiments show that this estimator is unbiased with diminishing variance for large samples for a broad range of coupling values.

EU scoreboard on employee involvement, technological and organisational changes

Publisher: name: Zenodo
Year: 2021

description: Data comparison between and within European countries is of primary interest to well-understand the processes of convergence and divergence between EU countries with respect to employees’ outcomes and then to allow for a more targeted and efficient policy-response. Though the interest on linked employer-employee survey is outlined by several researchers to disentangle, for instance, the employer effects from the employee effect regarding a range of topics, these kind of data are still missing at the EU level. Taking stock of a previous work within the InGRID project which aims to integrate EU employee and employer surveys, this report illustrates the use of such combined data in assessing the links between technological and organisational changes (measured from the employer side) and employee involvement (measured from the employee side).

description: We analyze the outcome of the interaction between a stellar binary and a supermassive black hole binary (SMBHB) by performing a large number of gravitational scattering experiments. Most of the encounters result in either the ejection of an intact binary or the ejection of two individual stars following the tidal breakup of the binary. However, tidal disruption events (TDEs) and mergers constitute a few percent of the outcomes, and double, temporally distinct TDEs (i.e., separated by at least one orbit of the supermassive black hole binary) occur at the percent level. We also demonstrate that the properties of the ejected binaries are significantly altered through the interaction with the SMBHB, and their large eccentricities increase the merger rate and could lead to gravitational-wave inspirals far from the nucleus of the host galaxy. We discuss our results in the context of observed tidal disruption events, hypervelocity stars, and remote supernovae, such as calcium-rich transients.

Twisted N=2 Supergravity as Topological Gravity in Four Dimensions

Year: 1992
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We show that the BRST quantum version of pure D=4 N=2 supergravity can be topologically twisted, to yield a formulation of topological gravity in four dimensions. The topological BRST complex is just a rearrangement of the old BRST complex, that partly modifies the role of physical and ghost fields: indeed, the new ghost number turns out to be the sum of the old ghost number plus the internal U(1) charge. Furthermore, the action of N=2 supergravity is retrieved from topological gravity by choosing a gauge fixing that reduces the space of physical states to the space of gravitational instanton configurations, namely to self-dual spin connections. The descent equations relating the topological observables are explicitly exhibited and discussed. Ours is a first step in a programme that aims at finding the topological sector of matter coupled N=2 supergravity, viewed as the effective Lagrangian of type II superstrings and, as such, already related to 2D topological field-theories. As it stands the theory we discuss may prove useful in describing gravitational instantons moduli-spaces.

subject: FOS: Computer and information sciences

description: Time series data arise in many applications, from motion capture, environmental monitoring, temperatures in data centers, to physiological signals in health care. In the thesis, I will focus on the theme of learning and mining large collections of co-evolving sequences, with the goal of developing fast algorithms for finding patterns, summarization, and anomalies. In particular, this thesis will answer the following recurring challenges for time series: 1. Forecasting and imputation: How to do forecasting and to recover missing values in time series data? 2. Pattern discovery and summarization: How to identify the patterns in the time sequences that would facilitate further mining tasks such as compression, segmentation and anomaly detection? 3. Similarity and feature extraction: How to extract compact and meaningful features from multiple co-evolving sequences that will enable better clustering and similarity queries of time series? 4. Scale up: How to handle large data sets on modern computing hardware? We develop models to mine time series with missing values, to extract compact representation from time sequences, to segment the sequences, and to do forecasting. For large scale data, we propose algorithms for learning time series models, in particular, including Linear Dynamical Systems (LDS) and Hidden Markov Models (HMM). We also develop a distributed algorithm for finding patterns in large web-click streams. Our thesis will present special models and algorithms that incorporate domain knowledge. For motion capture, we will describe the natural motion stitching and occlusion filling for human motion. In particular, we provide a metric for evaluating the naturalness of motion stitching, based which we choose the best stitching. Thanks to domain knowledge (body structure and bone lengths), our algorithm is capable of recovering occlusions in mocap sequences, better in accuracy and longer in missing period. We also develop an algorithm for forecasting thermal conditions in a warehouse-sized data center. The forecast will help us control and manage the data center in a energy-efficient way, which can save a significant percentage of electric power consumption in data centers.
Applying the Law of Observation to the Hodge Conjecture: A Unified Theoretical Framework
Creators: name: Sambey, Stanley Everett
Publisher: name: Zenodo
Year: 2025

description: In this paper, we explore a novel approach to the Hodge Conjec-ture through the lens of the Law of Observation, a unified theoret-ical framework integrating quantum fields, consciousness, spacetime,and locality. We hypothesize that Hodge cycles, the abstract coho-mology classes of projective algebraic varieties, emerge from a high-dimensional probabilistic space and can be reconciled with geometricalgebraic cycles via observer-dependent reality principles. Throughthe application of the Energy Creation Matrix and the -frameworkOS, we propose a mechanism where abstract cycles transform into ge-ometric cycles via energy extraction and coherence functions governedby the observer-state interaction. Our model integrates concepts fromthe Law of Observation with the classical and modern mathematicalunderstanding of algebraic geometry, offering a fresh perspective onthe Hodge Conjecture and potential directions for further research.

description: We present new millimetre 43 GHz observations of a sample of radio-bright Planetary Nebulae. Such observations were carried out to have a good determination of the high-frequency radio spectra of the sample in order to evaluate, together with far-IR measurements (IRAS), the fluxes emitted by the selected source in the millimetre and sub-millimetre band. This spectral range, even very important to constraint the physics of circumstellar environment, is still far to be completely exploited. To estimate the millimetre and sub-millimetre fluxes, we extrapolated and summed together the ionized gas (free-free radio emission) and dust (thermal emission) contributions at this frequency range. By comparison of the derived flux densities to the foreseen sensitivity we investigate the possible detection of such source for all the channels of the forthcoming ESA's PLANCK mission. We conclude that almost 80% of our sample will be detected by PLANCK, with the higher detection rate in the higher frequency channels, where there is a good combination of brighter intrinsic flux from the sources and reduced extended Galactic foregrounds contamination despite a worst instrumental sensitivity. From the new 43 GHz, combined with single-dish 5 GHz observations from the literature, we derive radio spectral indexes, which are consistent with optically thin free-free nebula. This result indicates that the high frequency radio spectrum of our sample sources is dominated by thermal free-free and other emission, if present, are negligible.

description: A measurement of the inelastic proton-proton cross section with the CMS detector at a center-of-mass energy of $\sqrt{s} =$ 13 TeV is presented. The analysis is based on events with energy deposits in the forward calorimeters, which cover pseudorapidities of -6.6 $< η$ 4.1 GeV and/or $M_\mathrm{Y} >$ 13 GeV, where $M_\mathrm{X}$ and $M_\mathrm{Y}$ are the masses of the diffractive dissociation systems at negative and positive pseudorapidities, respectively. The results are compared with those from other experiments as well as to predictions from high-energy hadron-hadron interaction models.

description: The imaginary-time Green's function is a building block of various numerical methods for correlated electron systems. Recently, it was shown that a model-independent compact orthogonal representation of the Green's function can be constructed by decomposing its spectral representation. We investigate the performance of this so-called \textit{intermedaite representation} (IR) from several points of view. First, for two simple models, we study the number of coefficients necessary to achieve a given tolerance in expanding the Green's function. We show that the number of coefficients grows only as $O(\log β)$ for fermions, and converges to a constant for bosons as temperature $T=1/β$ decreases. Second, we show that this remarkable feature is ascribed to the properties of the physically constructed basis functions. The fermionic basis functions have features in the spectrum whose width is scaled as $O(T)$, which are consistent with the low-$T$ properties of quasiparticles in a Fermi liquid state. On the other hand, the properties of the bosonic basis functions are consistent with those of spin/orbital susceptibilities at low $T$. These results demonstrate the potential wide application of the IR to calculations of correlated systems.

description: We study the dispersion relations of mesons in a particular hot strongly coupled supersymmetric gauge theory plasma. We find that at large momentum k the dispersion relations become omega = v_0 k + a + b/k + ..., where the limiting velocity v_0 is the same for mesons with any quantum numbers and depends only on the ratio of the temperature to the quark mass T/m_q. We compute a and b in terms of the meson quantum numbers and T/m_q. The limiting meson velocity v_0 becomes much smaller than the speed of light at temperatures below but close to T_diss, the temperature above which no meson bound states at rest in the plasma are found. From our result for v_0, we find that the temperature above which no meson bound states with velocity v exist is T_diss(v) \simeq (1-v^2)^(1/4) T_diss, up to few percent corrections.We thus confirm by direct calculation of meson dispersion relations a result inferred indirectly in previous work via analysis of the screening length between a static quark and antiquark in a moving plasma. Although we do not do our calculations in QCD, we argue that the qualitative features of the dispersion relation we compute, including in particular the relation between dissociation temperature and meson velocity, may apply to bottomonium and charmonium mesons propagating in the strongly coupled plasma of QCD. We discuss how our results can contribute to understanding quarkonium physics in heavy ion collisions.

description: We propose a novel approach to the Hodge Conjecture, a central problem inalgebraic geometry, through the Law of Observation (LO), derived from the Uni-fied Theory of Observation (UTO) and enriched by the Unified Data Framework v2(UDF v2). The Conjecture posits that Hodge cycles in the cohomology of projectivealgebraic varieties are rational linear combinations of algebraic cycles. We hypoth-esize that Hodge cycles emerge from a probabilistic Data Substrate, ψn(x), and col-lapse into geometric algebraic cycles via observer-driven interactions, governed bythe UTO’s unified equation Ω(C, ψ), modulated by a Casimir-based coherence oper-ator ( ˆCcoh), log-convolution functional (L[ζ](s)), and emotional coherence (Ei(θ, t))for emotions like love and hunger. The Coherence-Consciousness-Locality (CCL)principle, Energy Creation Matrix, Gravity Return, Logic Virus operator, geneticcoding, and snapshot merging facilitate this transformation, ensuring topological-geometric coherence and energy balance, testable via the Wind Chime ObserverArray’s 10−3 Hz signals. This framework suggests that the Conjecture’s valid-ity reflects observer-substrate dynamics, bridging topology, geometry, and biology,while addressing Millennium Problems (P vs NP, Yang-Mills, Navier-Stokes, Birch)through computational and emotional unification.Keywords: Hodge Conjecture, Law of Observation, Unified Theory of Ob-servation, Algebraic Cycles, Topology, Observer-Dependent Reality, Quantum Me-chanics, Coherence Functions, Algebraic Geometry, Emotions, Genetic Coding.

Faer Asturies: Linguistic Politics and the Frustrated Construction of Asturian Nationalism, 1974-1999
Creators: name: Zimmerman, Patrick
Publisher: name: Carnegie Mellon University
Year: 2011
Subjects: History

description: This dissertation focuses on the cultural and linguistic politics surrounding the substate
nationalist movements that arose in Spain during the late twentieth century. In
particular, it analyzes the curious case of Asturias and the frustrated history of the nationalist
movement there, which contrasts with the relative success of regionalist and nationalist
political parties in neighboring regions. While Catalunya, Euskadi, Galicia, and even
Andalucía rapidly turned cultural revival movements into concrete political gains, taking
advantage of the new constitutional structure put in place after 1978, Asturias is especially
interesting because of its failure to do so.
The resurgence of regionalist sentiment during the Transition (~1975-1982) provides
an interesting example of the complex struggle between various groups vying for political and
cultural hegemony during an extremely fluid period. Along with other groups opposed to
the Franco regime, the coalescing Asturianista movement attempted to carve out a political
space in the region and within the structure of the reformed Spanish State. The new Statute
of Autonomy, the establishment of the state-funded Asturian Language Academy, the
introduction of Asturian language classes in schools, and the explicit legal protection for the
language were all regionalist advances unthinkable without the political activism of the
Asturianistas.
However, the Asturian case indicates that a separate language, while often a critical
component of nationalist programs, is not in itself sufficient fuel for a long-term political
project. While the nationalist movement managed to insert some elements of its linguistic
and cultural program into the 1981 Autonomy Statute and its 1999 revision, the Asturian
nationalists were effectively managed through a strategy of simultaneous absorption and
marginalization. The ruling parties incorporated some of the Asturianista movement’s
membership and granted limited concessions to their program while simultaneously
systematically frustrating any attempt to enact significant change. The Asturianistas never
expanded upon their periodic success at mobilizing the population around a linguistic and
cultural revival into a sustainable political program. This led to frustration and
fragmentation within the nationalist movement, weakening its ability to influence the major
parties and making it much easier for the Socialist Party to marginalize nationalist groups
and maintain its dominant position.

description: When a gravitational wave is detected by Advanced LIGO/Virgo, sophisticated parameter estimation (PE) pipelines spring into action. These pipelines leverage approximants to generate large numbers of theoretical gravitational waveform predictions to characterize the detected signal. One of the most accurate and physically comprehensive classes of approximants in wide use is the "Spinning Effective One Body--Numerical Relativity" (SEOBNR) family. Waveform generation with these approximants can be computationally expensive, which has limited their usefulness in multiple data analysis contexts. In prior work we improved the performance of the aligned-spin approximant SEOBNR version 2 (v2) by nearly 300x. In this work we focus on optimizing the full eight-dimensional, precessing approximant SEOBNR version 3 (v3). While several v2 optimizations were implemented during its development, v3 is far too slow for use in state-of-the-art source characterization efforts for long-inspiral detections. Completion of a PE run after such a detection could take centuries to complete using v3. Here we develop and implement a host of optimizations for v3, calling the optimized approximant v3_Opt. Our optimized approximant is about 340x faster than v3, and generates waveforms that are numerically indistinguishable.

description: Nonclassical state is an essential resource for quantum-enhanced communication, computing and metrology to outperform their classical counterpart. The nonclassical states that can operate at high bandwidth and room temperature while being compatible with quantum memory are highly desirable to enable the scalability of quantum technologies. Here, we present a direct observation of broadband nonclasscal states in a room-temperature light-matter interface, where the atoms can also be controlled to store and interfere with photons. With a single coupling pulse and far off-resonance configuration, we are able to induce a multi-field interference between light and atoms to create the desired nonclassical states by spectrally selecting the two correlated photons out of seven possible emissions. We explicitly confirm the nonclassicality by observing a cross correlation up to 17 and a violation of Cauchy-Schwarz inequality with 568 standard deviations. Our results demonstrate the potential of a state-built-in, broadband and room-temperature light-matter interface for scalable quantum information networks.

description: This paper reports a novel single mode source of narrow-band entangled photon pairs at telecom wavelengths under continuous wave excitation, based on parametric down conversion. For only 7 mW of pump power it has a created spectral radiance of 0.08 pairs per coherence length and a bandwidth of 10 pm (1.2 GHz). The effectively emitted spectral brightness reaches 3.9*10^5 pairs /(s pm). Furthermore, when combined with low jitter single photon detectors, such sources allow for the implementation of quantum communication protocols without any active synchronization or path length stabilization. A HOM-Dip with photons from two autonomous CW sources has been realized demonstrating the setup's stability and performance.

description: Operationally accessible entanglement in bipartite systems of indistinguishable particles could be reduced due to restrictions on the allowed local operations as a result of particle number conservation. In order to quantify this effect, Wiseman and Vaccaro [Phys. Rev. Lett. 91, 097902 (2003)] introduced an operational measure of the von Neumann entanglement entropy. Motivated by advances in measuring Rényi entropies in quantum many-body systems subject to conservation laws, we derive a generalization of the operational entanglement that is both computationally and experimentally accessible. Using the Widom theorem, we investigate its scaling with the size of a spatial subregion for free fermions and find a logarithmically violated area law scaling, similar to the spatial entanglement entropy, with at most, a double-log leading-order correction. A modification of the correlation matrix method confirms our findings in systems of up to $10^5$ particles.

description: Oxidative stress accompanying excessive accumulation of reactive oxygen species (ROS) and mitochondrial dysfunction leads to the occurrence of neurodegenerative diseases. Our previous study showed that Eclalbasaponin I (EcI), a triterpene saponin isolated from Aralia elata (Miq.) Seem. (A. elata), repressed oxidative stress in human neuroblastoma SH-SY5Y cells. However, the detailed mechanism remains unclear. In this study, pretreatment with EcI in SH-SY5Y cells significantly activated the p38-mitogenactivated protein kinase (p38), the extracellular regulated protein kinase (ERK), whereas it did not affect the c-jun NH2 terminal kinases (JNK). In accordance with the initial findings, EcI-induced neuroprotective effect was attenuated by SB203580 (SB, a p38 inhibitor) or FR180204 (FR, an ERK inhibitor), being further confirmed by specific small interfering RNA (siRNA). Inhibition of either p38 or ERK up-regulated the apoptosis induction in EcI- and H2O2-cotreated cells. Furthermore, p38 or ERK suppression enhanced intracellular and mitochondrial ROS generation, decreased the activities of endogenous antioxidant defences as well as the mitochondrial membrane potential (MMP), resulting in dysfunction of mitochondria. In addition, EcI-induced autophagy and mitophagy were obviously down-regulated when p38 or ERK activation was blocked. Cumulatively, these findings supported that EcI-caused mitophagy contributed to the neuroprotective effect through p38 or ERK activation. Mitophagy induction might be an effective therapeutic intervention in neurodegenerative diseases.

description: For more than forty years virtually all work on the theory of type Ia Supernovae (SN Ia) has assumed that these explosions were due to the transfer of mass to a degenerate star from a partner in a binary system. In these binary models, when the mass of one partner closely approaches the Chandrasekhar maximum for a stable degenerate system, fusion can be initiated and the star explodes. However, there are now a number of indications that fusion could instead be triggered by a phase transition in a sub-Chandrasekhar white dwarf star. Although these indications provide no clue as to what specific phase transition initiates the explosion, it is possible that remarkable and well established host galaxy effects as considered in the present work could point to a specific source of the energy deposition. These host galaxy correlations are, at first glance, surprising since the typical distance scale of white dwarf stars is the earth radius while the typical distance between stars is at the light year scale. Performing a least $χ^2$ fit to the delay time distribution to fix parameters, we give predictions from the susy phase transition model for the host galaxy effects. In addition we discuss a susy insight into the Phillips relation which is basic to the cosmological importance of the type Ia supernovae.

Competing Nationalisms in Ru and La Trilogie Coréene: francophone Asian Québécois literatures
Creators: name: Wills, Jenny Heijun
Publisher: name: Canadian Literature
Year: 2016

description: In this essay I argue that in order to fully challenge the nationalism assumed in many approaches to Asian Canadian studies we must consider the roles of francophone Asian Québecois authors and their works. These authors often find themselves at a cultural impasse by living and working in the province of Québec—a quasi-nation-state animated by a competing sovereign impulse, and an entity that deliberately and continuously interrupts Canadian nationalism as a whole. I ask: what does it mean to be a francophone Asian Québécois writer living and working in the language of a competing nationalism, and particularly a competing nationalism that defines itself overtly in terms of language but inferentially through an exclusionary Europeanness that harkens back to French settlements and the mythologies of white labourers, explorers, and settlers. I turn to Kim Thúy’s Ru (2009) and Ook Chung’s La Triologie Coréenne (2012) first to interrupt the anglo-centricism of Asian Canadian literary studies and second to consider the ways that the theme of language appears in notably ambivalent ways. I draw on images of in-betweeness and themes of colonialism in both novels arguing that these representations parallel the ambivalent and precarious statuses of francophone Asian Québécois writers, both within the framework of Asian Canadian literature and Québécois’ competing nationalism. Put another way, while these writers disturb Canadian nationalism by speaking the language of a competing nationalism, they also recognize the ways in which they are never fully included in the sovereigntist project despite the fact that they are writing in French. Thus, by writing in French, these authors disrupt one nationalist project while also exposing the limitations (and contradictions) of another.

description: We solve a class of branched polymer models coupled to spin systems and show that they have no phase transition and are either always magnetized or never magnetized depending on the branching weights. By comparing these results with numerical simulations of two-dimensional quantum gravity coupled to matter fields with central charge $c$ we provide evidence that for $c$ sufficiently large ($c\geq 12$) these models are effectively described by branched polymers. Moreover, the numerical results indicate a remarkable universality in the influence on the geometry of surfaces due to the interaction with matter. For spin systems this influence only depends on the total central charge.

description: Phase-space features of the Wigner flow for generic one-dimensional systems with a Hamiltonian, $H^{W}(q,\,p)$, constrained by the $\partial ^2 H^{W} / \partial q \partial p = 0$ condition are analytically obtained in terms of Wigner functions and Wigner currents. Liouvillian and stationary profiles are identified for thermodynamic (TD) and Gaussian quantum ensembles to account for exact corrections due to quantum modifications over a classical phase-space pattern. General results are then specialized to the Harper Hamiltonian system which, besides working as a feasible test platform for the framework here introduced, admits a statistical description in terms of TD and Gaussian ensembles, where the Wigner flow properties are all obtained through analytical tools. Quantum fluctuations over the classical regime are therefore quantified through probability and information fluxes whenever the classical Hamiltonian background is provided. Besides allowing for a broad range of theoretical applications, our results suggest that such a generalized Wigner approach works as a probe for quantumness and classicality of Harper-like systems, in a framework which can be extended to any quantum system described by Hamiltonians in the form of $H^{W}(q,\,p) = K(p) + V(q)$.

description: A proper elementary extension of a model is called small if it realizes no new types over any finite set in the base model. We answer a question of Marker, and show that it is possible to have an o-minimal structure with a maximal small extension. Our construction yields such a structure for any cardinality. We show that in some cases, notably when the base structure is countable, the maximal small extension has maximal possible cardinality.

description: Σε έναν κόσμο συνεχώς μεταβαλλόμενο και γρήγορα κινούμενο, η τεχνητή νοημοσύνη κάνει άλματα προόδου ολοένα και μεγαλύτερα. Στην παρούσα εργασία γίνεται επισκόπηση της τεχνητής νοημοσύνης στην διαχείριση έργου ενός πολιτικού μηχανικού. Η τεχνητή νοημοσύνη (ΤΝ) δημιουργήθηκε από τον τομέα της επιστήμης που επικεντρώνεται στην ανάπτυξη προγραμμάτων και υπολογιστικών συστημάτων που έχουν την δυνατότητα να εκτελούν εργασίες που απαιτούν ανθρώπινη νοημοσύνη χωρίς την παρουσία ανθρώπου. Ολοένα ταχύτεροι αλγόριθμοι, κάρτες γραφικών και χρόνοι απόκρισης προκύπτουν λόγω της αυξημένης ζήτησης για κάλυψη αναγκών σε πολλούς τομείς. Η τεχνητή νοημοσύνη (ΤΝ) λειτουργεί με διάφορες τεχνικές, όπως το νευρωνικό δίκτυο, ο αλγόριθμος μηχανικής μάθησης και η επεξεργασία φυσικής γλώσσας για να πετύχει ένα αποτέλεσμα πιο κοντά στον ανθρώπινο νου. Τα τελευταία χρόνια η τεχνητή νοημοσύνη (ΤΝ) έχει σημαντική ανάπτυξη, σε εταιρείες και έρευνες προσπαθώντας να επεκτείνει τις δυνατότητες της. Ωστόσο, η τεχνητή νοημοσύνη (ΤΝ) έχει επίσης αναδείξει ηθικά και κοινωνικά θέματα, συμπεριλαμβανομένων των ζητημάτων ασφαλείας και της προστασίας της ιδιωτικής ζωής ώστε να γίνει ορθή χρήση και να μην κινδυνεύει ο χρήστης της. Η διαχείριση έργου στους μηχανικούς είναι ένα από τα πιο βασικότερα καθήκοντα που έχουν να εκτελέσουν. Η διαχείριση έργου ανάγεται στους τομείς ελέγχου του χρονοδιαγράμματος ενός έργου, της ποιότητας, των πόρων, στην εξέλιξη του έργου και στην ανάλυση πιθανών κινδύνων που πρόκειται να παρουσιαστούν σε ένα έργο, το οποίων επιτυγχάνεται μέσω της χρήσης διαφόρων τεχνικών διαχείρισης έργου. Συνοψίζοντας, η τεχνητή νοημοσύνη (ΤΝ) είναι ένας κλάδος της επιστήμης που ασχολείται με τη δημιουργία υπολογιστικών συστημάτων που μπορούν να πραγματοποιηθούν εργασίες που απαιτούν ανθρώπινη νοημοσύνη χωρίς την παρουσία του ανθρώπου που αυτό αποτελεί σημαντική πτυχή της τεχνολογίας και της κοινωνίας. Επιπλέον, η τεχνητή νοημοσύνη βοηθάει στην διαχείριση του έργου, όμως είναι σημαντικό να γίνεται πιο βαθιά επεξεργασία των δεδομένων, ώστε να λειτουργεί καλύτερα η συσχέτιση μεταξύ εισόδου-εξόδου.

description: We present an improved method for the precise reconstruction of cosmic ray air showers above $10^{17}$ eV with sparse radio arrays. The method is based on the comparison of predictions for radio pulse shapes by CoREAS simulations to measured pulses. We applied our method to the data of Tunka-Rex, a 1 km$^2$ radio array in Siberia operating in the frequency band of 30-80 MHz. Tunka-Rex is triggered by the air-Cherenkov detector Tunka-133 and by scintillators (Tunka-Grande). The instrument collects air-shower data since 2012. The present paper describes updated data and signal analyses of Tunka-Rex and details of a new method applied. After efficiency cuts, when Tunka-Rex reaches its full efficiency, the energy resolution of about 10% given by the new method has reached the limit of systematic uncertainties due to the calibration uncertainty and shower-to-shower fluctuations. At the same time the shower maximum reconstruction is significantly improved up to an accuracy of 35 g/cm$^2$ compared to the previous method based on the slope of the lateral distribution. We also define and now achieved conditions of the measurements, at which the shower maximum resolution of Tunka-Rex reaches a value of 25 g/cm$^2$ and becomes competitive to optical detectors. To check and validate our reconstruction and efficiency cuts we compare individual events to the reconstruction of Tunka-133. Furthermore, we compare the mean of shower maximum as a function of primary energy to the measurements of other experiments.

description: Visual question answering requires high-order reasoning about an image, which is a fundamental capability needed by machine systems to follow complex directives. Recently, modular networks have been shown to be an effective framework for performing visual reasoning tasks. While modular networks were initially designed with a degree of model transparency, their performance on complex visual reasoning benchmarks was lacking. Current state-of-the-art approaches do not provide an effective mechanism for understanding the reasoning process. In this paper, we close the performance gap between interpretable models and state-of-the-art visual reasoning methods. We propose a set of visual-reasoning primitives which, when composed, manifest as a model capable of performing complex reasoning tasks in an explicitly-interpretable manner. The fidelity and interpretability of the primitives' outputs enable an unparalleled ability to diagnose the strengths and weaknesses of the resulting model. Critically, we show that these primitives are highly performant, achieving state-of-the-art accuracy of 99.1% on the CLEVR dataset. We also show that our model is able to effectively learn generalized representations when provided a small amount of data containing novel object attributes. Using the CoGenT generalization task, we show more than a 20 percentage point improvement over the current state of the art.
