description: Η αυξανόμενη επιρροή του υπολογιστή έχει καταστήσει απαραίτητη τη δημιουργία συστημάτων όλο και πιο φιλικών προς τον άνθρωπο. Ένας πολλά υποσχόμενος τομέας έρευνας, ο οποίος τα τελευταία χρόνια έχει συγκεντρώσει το ενδιαφέρον πλήθους επιστημών, είναι η «Συναισθηματική υπολογιστική». Ο τομέας αυτός αποτελεί έναν κλάδο μελέτης και ανάπτυξης της τεχνητής νοημοσύνης, ο οποίος εξετάζει τη δημιουργία συστημάτων και συσκευών που μπορούν να αναγνωρίσουν, να ερμηνεύσουν και να επεξεργαστούν τα ανθρώπινα συναισθήματα. Δεδομένου του ουσιαστικού ρόλου της αυτόματης αναγνώρισης συναισθημάτων στην ανάπτυξη συναισθηματικών ευφυών συστημάτων, αντικείμενο της παρούσας εργασίας είναι η ανάπτυξη ενός λεξικού συναισθημάτων (affect lexicon) το οποίο θα αποτελεί τη βάση της δημιουργίας ενός συστήματος που θα εντοπίζει τα συναισθήματα σε ελληνικές ή αγγλικές προτάσεις. Το προτεινόμενο λεξικό διαμορφώθηκε με τον ίδιο αλγόριθμο που χρησιμοποιήθηκε και στο αντίστοιχο λεξικό του λογισμικού Synesketch. Οι ελληνικές λέξεις που περιέχονται στο λεξικό κατηγοριοποιούνται σύμφωνα με τους βασικούς τύπους συναισθημάτων, όπως ορίζονται από το μοντέλο του Ekman (χαρά, λύπη, θυμός, φόβος, απέχθεια, έκπληξη).
description: The increasing influence of the computer has made it necessary to develop systems more and more friendly to humans. One promising area of research, which in recent years has garnered the interest of numerous scientists, is the Affective computing. This term is a field of study and development of artificial intelligence that consider the creation of systems and devices that can recognize, interpret and process human emotions. Considering the highly important role of automated emotion recognition in the development of affective intelligent systems, the subject of this study is the construction of an affect lexicon which can constitute the base of the development of an emotion detection system for Greek or English sentences. The development of the proposed lexicon is based on Synesketch project. In this research work we used the algorithm proposed by Synesketch. Greek words that lexicon contains are classified to basic emotional types defined by Ekman’s model (happiness, sadness, anger, fear, disgust and surprise).

description: Στην εργασία αυτή πραγματοποιήθηκε η σύνθεση δώδεκα (12) νέων υποκατεστημένων και μη 2-(6-μεθοξυ[d]θειαζολ-2-υλιμινο) θειαζολ-5-βενζυλίδενο -4-ονών. Οι βιβλιογραφικές αναφορές και η συμβολή του υπολογιστικού προγράμματος PASS οδήγησαν στο σχεδιασμό των ενώσεων που συνδυάζουν δυο ετεροκυκλικούς δακτυλίους στο μόριο τους, του βενζοθειαζολίου και της 4-θειαζολιδινόνης. Η σύνθεση των βενζοθειαζολιδινονών πραγματοποιηθήκε σε τρία στάδια. Στο πρώτο στάδιο η αρχική αμίνη αντιδρά με το χλωροακετυλοχλωρίδιο και το προϊόν της αντίδρασης της με την επίδραση θειοκυανιούχου αμμωνίου κυκλοποιείται δίνοντας τη βενζοθειαζολιδινόνη η οποία αντιδρά με τις αντίστοιχες αρωματικές αλδεΰδες σχηματίζοντας τα τελικά προϊόντα. Οι ενώσεις ταυτοποιηθήκαν με φασματοσκοπικές μελέτες (IR και ΝΜR) . Έγινε υπολογιστική πρόβλεψη της λιποφιλικότητας των ενώσεων που συντέθηκαν. Πραγματοποιηθήκε in vivo μελέτη της αντιφλεγμονώδους δράση των ενώσεων με τη χρήση του μοντέλου της καρραγενίνης, καθώς και in vitro μελέτη της αναστολή της λιποξυγονάσης σόγιας (LOX). Τέλος μελετηθήκε η αντιμικροβιακή δράση των ενώσεων έναντι θετικών και αρνητικών κατά Gram βακτηρίων καθώς και μυκήτων.
description: This work presents and discusses the synthesis and evaluation of biological activity of twelve novel 2-(6-methoxybenzo[d]thiazol-2-ylimino)-5-benzylidene-thiazolidin-4-ones. Hybrid compounds containing benzothiazole and 4-thiazolidinone moieties were designed. The biological activity of the chemical compounds was predicted by the program PASS. The synthesis was performed in three steps. The final compounds were obtained by refluxing 2- ( 6-methoxybenzo [d] thiazol-2- ylimino) thiazolidin-4-one with aromatic aldehydes. Spectrometric methods ((IR, 1H-NMR) were used for the identification of compounds. The lipophilicity of compounds was calculated theoretically. Compounds were evaluated for their anti-inflammatory activity using carrageenin-induced mouse paw edema and were tested in vitro for their LOX inhibitory activity. Also , they were tested for their antibacterial and antifungal activity.

description: In this Letter we pose the question of whether a many-body quantum system with a full set of conserved quantities can relax to an equilibrium state, and, if it can, what the properties of such state are. We confirm the relaxation hypothesis through a thorough ab initio numerical investigation of the dynamics of hard-core bosons on a one-dimensional lattice. Further, a natural extension of the Gibbs ensemble to integrable systems results in a theory that is able to predict the mean values of physical observables after relaxation. Finally, we show that our generalized equilibrium carries more memory of the initial conditions than the usual thermodynamic one. This effect may have many experimental consequences, some of which having already been observed in the recent experiment on the non-equilibrium dynamics of one-dimensional hard-core bosons in a harmonic potential [T. Kinoshita, T. Wenger, D. S. Weiss, Nature (London) 440, 900 (2006)].

Kondo screening cloud in a one dimensional wire: Numerical renormalization group study

description: We study the Kondo model --a magnetic impurity coupled to a one dimensional wire via exchange coupling-- by using Wilson's numerical renormalization group (NRG) technique. By applying an approach similar to which was used to compute the two impurity problem we managed to improve the bad spatial resolution of the numerical renormalization group method. In this way we have calculated the impurity spin - conduction electron spin correlation function which is a measure of the Kondo compensation cloud whose existence has been a long standing problem in solid state physics. We also present results on the temperature dependence of the Kondo correlations.

Information-Theoretic Abstractions for Resource-Constrained Agents via Mixed-Integer Linear Programming

description: In this paper, a mixed-integer linear programming formulation for the problem of obtaining task-relevant, multi-resolution, graph abstractions for resource-constrained agents is presented. The formulation leverages concepts from information-theoretic signal compression, specifically the information bottleneck (IB) method, to pose a graph abstraction problem as an optimal encoder search over the space of multi-resolution trees. The abstractions emerge in a task-relevant manner as a function of agent information-processing constraints, and are not provided to the system a priori. We detail our formulation and show how the problem can be realized as an integer linear program. A non-trivial numerical example is presented to demonstrate the utility in employing our approach to obtain hierarchical tree abstractions for resource-limited agents.

description: We present a novel technique for the calculation of dynamical correlation functions of quantum impurity systems in equilibrium with Wilson's numerical renormalization group. Our formulation is based on a complete basis set of the Wilson chain. In contrast to all previous methods, it does not suffer from overcounting of excitation. By construction, it always fulfills sum rules for spectral functions. Furthermore, it accurately reproduces local thermodynamic expectation values, such as occupancy and magnetization, obtained directly from the numerical renormalization group calculations.

description: We explore the Hawking evaporation of two-dimensional anti-de Sitter (AdS$_2$), dilatonic black hole coupled with conformal matter, and derive the Page curve for the entanglement entropy of radiation. We first work in a semiclassical approximation with backreaction. We show that the end-point of the evaporation process is AdS$_2$ with a vanishing dilaton, i.e. a regular, singularity-free, zero-entropy state. We explicitly compute the entanglement entropies of the black hole and the radiation, as functions of the horizon radius, using the conformal field theory (CFT) dual to AdS$_2$ gravity. We use a simplified toy model, in which evaporation is described by the forming and growing of a negative mass configuration in the positive-mass black hole interior. This is similar to the ``islands'' proposal, recently put forward to explain the Page curve for evaporating black holes. The resulting Page curve for AdS$_2$ black holes is in agreement with unitary evolution. The entanglement entropy of the radiation initially grows, closely following a thermal behavior, reaches a maximum at half-way of the evaporation process, and then goes down to zero, following the Bekenstein-Hawking entropy of the black hole. Consistency of our simplified model requires a non-trivial identification of the central charge of the CFT describing AdS$_2$ gravity with the number of species of fields describing Hawking radiation.

description: The PAX project at GSI Darmstadt plans to polarize an antiproton beam by repeated interaction with a hydrogen target in a storage ring. Many of the beam particles are required to remain within the ring after interaction with the target, so small scattering angles are important. Hence we concentrate on low momentum transfer (small t), a region where electromagnetic effects dominate the hadronic effects. A colliding beam of polarized electrons with energy sufficient to provide scattering of antiprotons beyond ring acceptance may polarize an antiproton beam by spin filtering. Expressions for spin observables are provided and are used to estimate the rate of buildup of polarization of an antiproton beam.

description: We investigate, in a four photon interference experiment in a laser-written waveguide structure, how symmetries control the suppression of many-body output events of a $J_x$ unitary. We show that totally destructive interference does not require mutual indistinguishability between all, but only between symmetrically paired particles, in agreement with recent theoretical predictions. The outcome of the experiment is well described by a quantitative simulation which accounts for higher order emission of the photon source, imbalances in the scattering network, partial distinguishability, and photon loss.

description: There are more than 200 thermal springs in Greece.The large number of Greek thermometallic resources is connected to the topography, tectonics, and the important existing volcanic factor. According to the Official Government’s publication on 06.11.2014, there are established criteria forthermal resources, based on their temperature, their minerality and their content of chemical elements, whichwill be analyzed. This study includes information regarding thermal springs in Central and Western Macedonia.Chemical analyzes that have been implemented, are the ones of the greatest importance in each case. They are also the more helpful factors in the classification of the springs. The aim of the study is to constitute a concentrated study of thermal springs in Central and Western Macedonia. The chemical type of each spring is being determined and there have been comparisons betweenolder and current analyzes. Finally, a new classification system, that gives the ability for an immediate comparison of the springs, is being suggested

description: Recent investigations address transport through ballistic charge-neutral graphene strips coupled to doped graphitic leads. This paper shows that identical transport properties arise when the leads are replaced by quantum wires. This duality between graphitic and metallic leads originates in the selection of modes with transverse momentum close to the K points, and can be extended to a wide class of contact models. Among this class we identify a simple, effective contact model, which provides an efficient tool to study the transport through extended weakly-doped graphitic systems.

description: We consider the inverse-folding problem for RNA secondary structures: for a given (pseudo-knot-free) secondary structure find a sequence that has that structure as its ground state. If such a sequence exists, the structure is called designable. We implemented a branch-and-bound algorithm that is able to do an exhaustive search within the sequence space, i.e., gives an exact answer whether such a sequence exists. The bound required by the branch-and-bound algorithm are calculated by a dynamic programming algorithm. We consider different alphabet sizes and an ensemble of random structures, which we want to design. We find that for two letters almost none of these structures are designable. The designability improves for the three-letter case, but still a significant fraction of structures is undesignable. This changes when we look at the natural four-letter case with two pairs of complementary bases: undesignable structures are the exception, although they still exist. Finally, we also study the relation between designability and the algorithmic complexity of the branch-and-bound algorithm. Within the ensemble of structures, a high average degree of undesignability is correlated to a long time to prove that a given structure is (un-)designable. In the four-letter case, where the designability is high everywhere, the algorithmic complexity is highest in the region of naturally occurring RNA.

description: Rehabilitation is important to improve quality of life for mobility-impaired patients. Smart walkers are a commonly used solution that should embed automatic and objective tools for data-driven human-in-the-loop control and monitoring. However, present solutions focus on extracting few specific metrics from dedicated sensors with no unified full-body approach. We investigate a general, real-time, full-body pose estimation framework based on two RGB+D camera streams with non-overlapping views mounted on a smart walker equipment used in rehabilitation. Human keypoint estimation is performed using a two-stage neural network framework. The 2D-Stage implements a detection module that locates body keypoints in the 2D image frames. The 3D-Stage implements a regression module that lifts and relates the detected keypoints in both cameras to the 3D space relative to the walker. Model predictions are low-pass filtered to improve temporal consistency. A custom acquisition method was used to obtain a dataset, with 14 healthy subjects, used for training and evaluating the proposed framework offline, which was then deployed on the real walker equipment. An overall keypoint detection error of 3.73 pixels for the 2D-Stage and 44.05mm for the 3D-Stage were reported, with an inference time of 26.6ms when deployed on the constrained hardware of the walker. We present a novel approach to patient monitoring and data-driven human-in-the-loop control in the context of smart walkers. It is able to extract a complete and compact body representation in real-time and from inexpensive sensors, serving as a common base for downstream metrics extraction solutions, and Human-Robot interaction applications. Despite promising results, more data should be collected on users with impairments, to assess its performance as a rehabilitation tool in real-world scenarios.

description: We give a spinorial characterization of isometrically immersed hypersurfaces into 4-dimensional space forms and product spaces $\M^3(κ)\times\R$, in terms of the existence of particular spinor fields, called generalized Killing spinors or equivalently solutions of a Dirac equation. This generalizes to higher dimensions several recent results for surfaces by T. Friedrich, B. Morel and the two authors. The main argument is the interpretation of the energy-momentum tensor of a generalized Killing spinor as the second fundamental form, possibly up to a tensor depending on the ambient space. As an application, we deduce a non-existence result for hypersurfaces in the 4-dimensional Euclidean space.

description: Η παρούσα εργασία σχεδιάστηκε για να μελετήσει την επίδραση των προσδιοριστικών παραγόντων που συνδέονται με τους εκπαιδευτικούς και την υλικοτεχνική υποδομή, στην κινητική δημιουργικότητα, την ευχέρεια και την πρωτοτυπία των παιδιών προσχολικής ηλικίας. Στην έρευνα συμμετείχαν 200 παιδιά και οι νηπιαγωγοί τους από νηπιαγωγεία της Ανατολικής Θεσσαλονίκης. Οι νηπιαγωγοί συμπλήρωσαν ερωτηματολόγια για την σχέση μεταξύ εκπαιδευτικού και μαθητή. Επίσης, έγινε καταγραφή του χώρου και του προγράμματος του μαθήματος. Στο τέλος, τα παιδιά εκτέλεσαν μια σειρά δραστηριοτήτων της κινητικής δοκιμασίας για να εντοπιστεί το επίπεδο και η δημιουργικότητα των κινήσεων τους. Τα αποτελέσματα των αναλύσεων έδειξαν πως η στενή σχέση με τους εκπαιδευτικούς, η ευελιξία του χώρου και η ποικιλία του χώρου επιδρούν θετικά και στους τρεις παράγοντες της δημιουργικής κινητικότητας του παιδιού, οι οποίοι είναι η ευχέρεια, η πρωτοτυπία και η φαντασία. Δεν επιβεβαιώθηκε όμως, η υπόθεση πως η συμμετοχή των ίδιων των εκπαιδευτικών σε κινητικές δραστηριότητες επιδρά θετικά, σε κανέναν παράγοντα της δημιουργικής κινητικότητας. Ωστόσο, εντοπίστηκε πως ο σωστός και έγκαιρος προγραμματισμός, επίσης βοηθά στην ανάπτυξη της δημιουργικότητας.

In the study participated 200 children and their teachers from kindergartens in Thessaloniki, North Greece. The kindergarten teachers completed a survey on measuring teacher- student interactions. School infrastructures were recorded by the researcher in the terms of space, equipment and the organization of the program . Furthermore, the children performed a creative movement motor test. The results of the analyses, indicated that flexibility of the space and variety of equipment, positively influenced all three aspects of child's creative movement, namely fluency, originality and imagination. The hypothesis on the positive influence of teachers’ - participation in the physical activities was not confirmed in any of the three aspects of creative movement of mobility. However, the results demonstrated that correct and timely planning of the program can also help in developing motor creativity. The findings of the study evident the significance of the development of physical education in preschool age and provide practical implications in order to maximize teacher’s influence on students’ motor creativity.

description: We study the canonical quantization of the theory given by Chamseddine-Connes spectral action on a particular finite spectral triple with algebra $M_2(\Cset)\oplus\Cset$. We define a quantization of the natural distance associated with this noncommutative space and show that the quantum distance operator has a discrete spectrum. We also show that it would be the same for any other geometric quantity. Finally we propose a physical Hilbert space for the quantum theory. This spectral triple had been previously considered by Rovelli as a toy model, but with a different action which was not gauge-invariant. The results are similar in both cases, but the gauge-invariance of the spectral action manifests itself by the presence of a non-trivial degeneracy structure for our distance operator.

description: The analysis of 20 years of spectrophotometric data of the double shell planetary nebula PM\,1-188 is presented, aiming to determine the time evolution of the emission lines and the physical conditions of the nebula, as a consequence of the systematic fading of its [WC\,10] central star whose brightness has declined by about 10 mag in the past 40 years. Our main results include that the [\ion{O}{iii}], [\ion{O}{ii}], [\ion{N}{ii}] line intensities are increasing with time in the inner nebula as a consequence of an increase in electron temperature from 11,000 K in 2005 to more than 14,000 K in 2018, due to shocks. The intensity of the same lines are decreasing in the outer nebula, due to a decrease in temperature, from 13,000 K to 7,000 K, in the same period. The chemical composition of the inner and outer shells was derived and they are similar. Both nebulae present subsolar O, S and Ar abundances, while they are He, N and Ne rich. For the outer nebula the values are 12+log He/H= 11.13$\pm$0.05, 12+log O/H = 8.04$\pm$0.04, 12+log N/H= 7.87$\pm$0.06, 12+log S/H = 7.18$\pm$0.10 and 12+log Ar = 5.33$\pm$0.16. The O, S and Ar abundances are several times lower than the average values found in disc non-Type I PNe, and are reminiscent of some halo PNe. From high resolution spectra, an outflow in the N-S direction was found in the inner zone. Position-velocity diagrams show that the outflow expands at velocities in the $-$150 to 100 km s$^{-1}$ range, and both shells have expansion velocities of about 40 km s$^{-1}$.

description: Σκοπός της διατριβής ήταν η μελέτη των γεωμετρικών συνθηκών για τη μέση αυξητικότητα ολόμορφων συναρτήσεων. Χρησιμοποιήσαμε αρχικά διάφορα εργαλεία, όπως τον πυρήνα Poisson, για να λάβουμε αποτελέσματα στο μοναδιαίο δίσκο όπως τη συνοριακή συμπεριφορά. Το θεώρημα Smirnov μας έδωσε ένα μερικό αντίστροφο σε αυτήν. Συνδυάζοντας αυτά με μελέτη αμφιμονότιμων συναρτήσεων πήραμε τα πρώτα γεωμετρικού τύπου αποτελέσματα. Ένας ισοδύναμος ορισμός που αφορά αρμονικές συναρτήσεις μας βοήθησε να γενικεύσουμε τη μελέτη μας σε αυθαίρετους τόπους. Ελέγχοντας την εικόνα τη συνάρτησης και χρησιμοποιώντας τον αριθμό Hardy και το θεώρημα Tsuji, λάβαμε σχετικά αποτελέσματα μέσω της μορφής (αστερόμορφοι ή σπειρόμορφοι τόποι) και του εμβαδού της. Παραθέσαμε επίσης παραδείγματα που αποδεικνύουν τη μη αναγκαιότητα διαφόρων συνθηκών.
description: The aim of the present thesis was the study of geometric conditions for the mean growth of holomorphic functions. First, we used several tools, such as the Poisson kernel, in order to get results on the unit disk such as the boundary behavior. Smirnov’s theorem gave us a partial inverse to this. Combining those with the study of univalent functions we got the first geometric-type results. An equivalent definition that features harmonic functions helped us generalize our study on arbitrary regions. By considering the image of a functions and using the Hardy number and Tsuji’s theorem, we got relevant results through its form (starlike or spiral-like) and its area. We also mention examples that prove the non-necessity of some of the conditions.

description: The small silicon chip of Schottky diode (0.8x0.8x0.4 mm3) with planar arrangement of electrodes (chip PSD) as temperature sensor, which functions under the operating conditions of pressure sensor, was developed. The forward I-V characteristic of chip PSD is determined by potential barrier between Mo and n-Si (ND = 3x1015 cm-3). Forward voltage UF = 208 mV and temperature coefficient TC = -1.635 mV/C (with linearity kT <0.4% for temperature range of -65 to +85 C) at supply current IF = 1 mA is achieved. The reverse I-V characteristic has high breakdown voltage UBR > 85 V and low leakage current IL < 5 μA at 25 C and IL < 130 μA at 85 C (UR = 20 V) because chip PSD contains the structure of two p-type guard rings along the anode perimeter. The application of PSD chip for wider temperature range from -65 to +115 C is proved. The separate chip PSD of temperature sensor located at a distance of less than 1.5 mm from the pressure sensor chip. The PSD chip transmits input data for temperature compensation of pressure sensor errors by ASIC and for direct temperature measurement.

description: The so-called aromatic infrared bands are attributed to emission of polycyclic aromatic hydrocarbons. The observed variations toward different regions in space are believed to be caused by contributions of different classes of PAH molecules, i.e. with respect to their size, structure, and charge state. Laboratory spectra of members of these classes are needed to compare them to observations and to benchmark quantum-chemically computed spectra of these species. In this paper we present the experimental infrared spectra of three different PAH dications, naphthalene$^{2+}$, anthracene$^{2+}$, and phenanthrene$^{2+}$, in the vibrational fingerprint region 500-1700~cm$^{-1}$. The dications were produced by electron impact ionization of the vapors with 70 eV electrons, and they remained stable against dissociation and Coulomb explosion. The vibrational spectra were obtained by IR predissociation of the PAH$^{2+}$ complexed with neon in a 22-pole cryogenic ion trap setup coupled to a free-electron infrared laser at the Free-Electron Lasers for Infrared eXperiments (FELIX) Laboratory. We performed anharmonic density-functional theory calculations for both singly and doubly charged states of the three molecules. The experimental band positions showed excellent agreement with the calculated band positions of the singlet electronic ground state for all three doubly charged species, indicating its higher stability over the triplet state. The presence of several strong combination bands and additional weaker features in the recorded spectra, especially in the 10-15~$μ$m region of the mid-IR spectrum, required anharmonic calculations to understand their effects on the total integrated intensity for the different charge states. These measurements, in tandem with theoretical calculations, will help in the identification of this specific class of doubly-charged PAHs as carriers of AIBs.

Access and accessibility to Canadian vital event records
Creators: name: Hemmings, Michael A.
Publisher: name: University of British Columbia
Year: 2008

description: The transfer of copies of vital event records into a government archives repository is necessary not only to ensure their ongoing preservation, but also to provide access and accessibility to them for all researchers in an appropriate setting. At present all vital event records gatekeepers in Canada, except two, do not have in place a system providing for such regular transferral. The central reason for this lack of process is the assumption that vital event records are somehow different in kind, and not just in type, from other public records that contain personal information. This thesis evaluates that assumption through an analysis of the history of vital statistics legislation and a comparative study of the privacy regime of that legislation with the legislative regime of access to information and privacy. Having done these two studies, the thesis then recommends a way in which legal transfer from the gatekeepers to the repository can be achieved. That recommendation is, first, that all discussion regarding access must be accomplished before their acquisition. Secondly, their acquisition and accessibility must be based upon the expiration of time—limits.

SASE FEL with energy-chirped electron beam and its application for generation of attosecond pulses

description: Influence of a linear energy chirp in the electron beam on a SASE FEL operation is studied analytically and numerically using 1-D model. Explicit expressions for Green's functions and for output power of a SASE FEL are obtained for high-gain linear regime in the limits of small and large energy chirp parameter. Saturation length and power versus energy chirp parameter are calculated numerically. It is shown that the effect of linear energy chirp on FEL gain is equivalent to the linear undulator tapering (or linear energy variation along the undulator). A consequence of this fact is a possibility to perfectly compensate FEL gain degradation, caused by the energy chirp, by means of the undulator tapering independently of the value of the energy chirp parameter. An application of this effect for generation of attosecond pulses from a hard X-ray FEL is proposed. Strong energy modulation within a short slice of an electron bunch is produced by few-cycle optical laser pulse in a short undulator, placed in front of the main undulator. Gain degradation within this slice is compensated by an appropriate undulator taper while the rest of the bunch suffers from this taper and does not lase. Three-dimensional simulations predict that short (200 attoseconds) high-power (up to 100 GW) pulses can be produced in Angstroem wavelength range with a high degree of contrast. A possibility to reduce pulse duration to sub-100 attosecond scale is discussed.

Pose Guided Person Image Generation with Hidden p-Norm Regression

Year: 2021
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: In this paper, we propose a novel approach to solve the pose guided person image generation task. We assume that the relation between pose and appearance information can be described by a simple matrix operation in hidden space. Based on this assumption, our method estimates a pose-invariant feature matrix for each identity, and uses it to predict the target appearance conditioned on the target pose. The estimation process is formulated as a p-norm regression problem in hidden space. By utilizing the differentiation of the solution of this regression problem, the parameters of the whole framework can be trained in an end-to-end manner. While most previous works are only applicable to the supervised training and single-shot generation scenario, our method can be easily adapted to unsupervised training and multi-shot generation. Extensive experiments on the challenging Market-1501 dataset show that our method yields competitive performance in all the aforementioned variant scenarios.

description: Diffusion vibrational modes are studied in superfluid $He^3-A$ in zero magnetic fields for different angles between the orbital axis and the wave vector. The dispersion relation for these modes is found to depend on the wave polarization. It is shown that in addition to the normal component velocity, the superfluid component velocity also oscillates in the diffusion modes of $He^3-A$. The frictional forces due to viscous waves in $He^3-A$, exerted in the plane surface which is in contact with a superfluid liquid layer of finite thickness and performs a simple harmonic oscillatory motion, are calculated. We also consider, volume of $He^3-A$ restricted by two parallel infinite surfaces, when the lower surface accomplishes simple harmonic oscillation and we calculate the frictional forces exerted on surfaces. It is found that the frictional force has not only parallel, but also a perpendicular component relative to the direction of oscillations.
