description: The Panoramic Survey Telescope And Rapid Response System (Pan-STARRS) under development at the University of Hawaii's Institute for Astronomy is creating the first fully automated end-to-end Moving Object Processing System (MOPS) in the world. It will be capable of identifying detections of moving objects in our solar system and linking those detections within and between nights, attributing those detections to known objects, calculating initial and differentially-corrected orbits for linked detections, precovering detections when they exist, and orbit identification. Here we describe new kd-tree and variable-tree algorithms that allow fast, efficient, scalable linking of intra and inter-night detections. Using a pseudo-realistic simulation of the Pan-STARRS survey strategy incorporating weather, astrometric accuracy and false detections we have achieved nearly 100% efficiency and accuracy for intra-night linking and nearly 100% efficiency for inter-night linking within a lunation. At realistic sky-plane densities for both real and false detections the intra-night linking of detections into `tracks' currently has an accuracy of 0.3%. Successful tests of the MOPS on real source detections from the Spacewatch asteroid survey indicate that the MOPS is capable of identifying asteroids in real data.

description: We study the Drell-Yan production cross section and structure functions in proton (deuteron)-nucleus collisions using the Color Glass Condensate formalism. The nucleus is treated in the Color Glass Condensate framework which includes both higher twist effects due to the inclusion of multiple scatterings and leading twist pQCD shadowing due to the small x resummation, while the proton (or deuteron) is treated within the DGLAP improved parton model. In particular, the Drell-Yan structure functions are used in order to investigate the Lam-Tung relation at small x, which is known to be identically zero at leading twist up to Next-to-Leading order, and is thus a good playground for studying higher twist effects. In agreement with this, we find that violations of this relation are more important for low momentum and invariant mass of the Drell-Yan pair, and also in the region of rapidity that corresponds to smaller values of x in the nucleus.

description: Dynamic treatment regimes are a set of decision rules and each treatment decision is tailored over time according to patients’ responses to previous treatments as well as covariate history. There is a growing interest in development of correct statistical inference for optimal dynamic treatment regimes to handle the challenges of nonregularity problems in the presence of nonrespondents who have zero-treatment effects, especially when the dimension of the tailoring variables is high. In this article, we propose a high-dimensional Q-learning (HQ-learning) to facilitate the inference of optimal values and parameters. The proposed method allows us to simultaneously estimate the optimal dynamic treatment regimes and select the important variables that truly contribute to the individual reward. At the same time, hard thresholding is introduced in the method to eliminate the effects of the nonrespondents. The asymptotic properties for the parameter estimators as well as the estimated optimal value function are then established by adjusting the bias due to thresholding. Both simulation studies and real data analysis demonstrate satisfactory performance for obtaining the proper inference for the value function for the optimal dynamic treatment regimes. Supplementary materials for this article are available online.

description: The biological phenomenon of stress is certainly older than man. However, it was Hans Selye who described and analyzed it scientifically in a number of different approaches. H. Selye defined biological stress (BS) as: “The non specific response of the body to any demand”. This was accepted by the international scientific community in the ‘70s. The distinction between the specific and the non specific responses of the body to different demands was the most important fact, the decisive step, in the scientific analysis of BS. There are three systems participating, cooperating and mutually influenced in the stress response: The Central Nervous System (CNS), the Endocrine and the Immune system. Following the application of the initial stimulus upon CNS, mediation of the stress response is achieved via: 1) the hypothalamus and the production of CRH (CRF), 2) the action of CRH, via the portal circulation, on the anterior lobe of pituitary and the liberation of ACTH, 3) ACTH acts on the adrenal cortex which produces and secretes corticoids. Thus, there is an activation of Hypothalamic – Pituitary – Adrenocortical (HPA) axis. This axis prepares the body for a long-lasting adaptation. HPA axis is mobilized shortly after the application of stressors. However, even before the HPA axis (few seconds after the application of the stressor), the sympathetic system reacts via catecholamines, as well as, the adrenal medulla with liberation of adrenaline. This Adrenergic – Adrenomedulary axis prepares the body for “fight or flight”

description: We investigate the probability distribution function of the free flight time and of the number of collisions in a hard sphere gas at equilibrium. At variance with naive expectation, the latter quantity does not follow Poissonian statistics, even in the dilute limit which is the focus of the present analysis. The corresponding deviations are addressed both numerically and analytically. In writing an equation for the generating function of the cumulants of the number of collisions, we came across a perfect mapping between our problem and a previously introduced model: the probabilistic ballistic annihilation process [Coppex et al., Phys. Rev. E 69 11303 (2004)]. We exploit this analogy to construct a Monte-Carlo like algorithm able to investigate the asymptotically large time behavior of the collisional statistics within a reasonable computational time. In addition, our predictions are confronted against the results of Molecular Dynamics simulations and Direct Simulation Monte Carlo technique. An excellent agreement is reported.

description: We present CCD $UBVI$ photometric study of poorly studied intermediate age open cluster SAI 35 (Juchert 20) for the first time. To accomplish this study, we also used LAMOST DR5, 2MASS, and Gaia EDR3 databases. We identified 214 most probable cluster members with membership probability higher than 50%. The mean proper motion of the cluster is found as μ_αcosδ=1.10 \pm 0.01 and μ_δ=-1.66 \pm 0.01 mas/yr. We find the normal interstellar extinction law using the various two-color diagrams. The age, distance, reddening, and radial velocity of the cluster are estimated to be 360 \pm 40 Myr, 2.9 \pm 0.15 kpc, 0.72 \pm 0.05 mag and -91.62 \pm 6.39 km/sec. The overall mass function slope for main-sequence stars is found to be 1.49\pm0.16 within the mass range 1.1-3.1 M_\odot, which is in agreement with Salpeter's value within uncertainty. The present study demonstrates that SAI 35 is a dynamically relaxed. Galactic orbital parameters are determined using Galactic potential models. We found that this object follows a circular path around the Galactic center.

description: We investigate the electron density distribution and the stability of stripe phases in the realistic two-band model with hopping elements between e_g orbitals at Ni sites on the square lattice, and compare these results with those obtained for the doubly degenerate Hubbard model with two equivalent orbitals and diagonal hopping. For both models we determine the stability regions of filled and half-filled stripe phases for increasing hole doping x=2-n in the range of x<0.4, using Hartree-Fock approximation for large clusters. In the parameter range relevant to the nickelates, we obtain the most stable diagonal stripe structures with filling of nearly one hole per atom, as observed experimentally. In contrast, for the doubly degenerate Hubbard model the most stable stripes are somewhat reminiscent of the cuprates, with half-filled atoms at the domain wall sites. This difference elucidates the crucial role of the off-diagonal e_g hopping terms for the stripe formation in La_2-xSr_xNiO_4. The influence of crystal field is discussed as well.

description: We re-examine the re-scattering mechanism for the X(3872), as a candidate for the 2P charmonium state $χ_{c1}(2P)$, decaying to $J/ψρ(ω)$ through exchanging $D^{(*)}$ mesons between intermediate states $D(\bar{D})$ and $\bar{D}^*(D^*)$. We evaluate the dispersive part, as well as the absorptive one, of the re-scattering amplitude and find that the contribution from the dispersive part is dominant even when X(3872) lies above the threshold of the neutral channel $th_n=m_{D^0}+m_{D^{*0}}$. We predict $R_{ρ/ω}\simeq 1$ for the $m_X$ region scanned by experiments. Meanwhile, we also estimate the rate of $X\to D^0\bar{D}^{0}π^0$. Our results favor a charmonium interpretation of X(3872) when it lies slightly below the threshold of $D^0\bar{D}^{*0}$. Furthermore, we evaluated the width of $X\to J/ψρ$ with the help of a phenomenological effective coupling constant $g_X$, and find the total width of X(3872) to be in the range of 1-2 MeV.

Η πρωτεϊνη SAFB1 αλληλεπιδρά με την πρωτεϊνη p53 και ρυθμίζει τη μεταγραφική της ενεργότητα. Ακολούθησε μελέτη της φωσφορυλίωσης του υποδοχέα της λαμίνης Β (LBR) από την SRPK1. Η φωσφορυλίωση του αμινοτελικού άκρου του LBR από την SRPK1 αυξάνει την διαλυτότητά του. To φωσφορυλιωμένο αμινοτελικό άκρο αλληλεπιδρά με την ιστόνη Η3, ενώ αντίθετα η φωσφορυλίωση δεν έχει καμία επίδραση στην αλληλεπίδρασή του με την ετεροχρωματινική πρωτεϊνη ΗΡ1.

Η φωσφορυλίωση της σερίνης 9 παίζει καθοριστικό ρόλο στην αλληλεπίδραση της πρωταμίνης 1 με το αμινοτελικό άκρο του LBR και στην υποκυτταρική της εντόπιση
description: The elucidation of the biological function(s) of SR protein kinases was the main goal of this doctoral dissertation. SAFB1 and p53 interact with SRPK1a. A fraction of nuclear p53 bound to and co-localized with SAFB1. Binding of p53 to SAFB1 was shown to be functionally significant, since SAFB1 suppressed p53-mediated reporter gene expression in p53-null cells(K562) doubly transfected with p53 and SAFBq. In a following step, we studied the effect of phosphorylation of the RS domain of LBR, by SRPK1, on its structure and on its interaction with histone H3 and HP1. Association with RNA molecules or phosphorylation of the RS domain, renders the NH2-terminal part of pLBR soluble. Phosphorylation was found to promote binding of histone H3, whereas we did not observe any effect on HP1 association. Finally, we demostrated that phosphorylated protamine 1 binds specifically to the RS region of LBR. Mutation of Ser 9 to Ala completely abolished the interaction of protamine 1 with the NH2-terminal part of LBR

Computation of chance levels for classification between men and women. To determine the chance levels for sex classification accuracies, we performed 1000-run permutation tests in NCAβ-, NCAβ+, MCIAβ-, MCIAβ+ and ADAβ+ subjects, respectively. For each permutation run, we randomly shuffled the sex labels in that diagnostic group and followed the exact original classification schema described in section 2.2.4. Accuracy of each permutation run was finally recorded for each diagnostic group. Figure S2. below plots the empirical distribution of the classification accuracies in NCAβ-, NCAβ+, MCIAβ-, MCIAβ+ and ADAβ+ subjects during 1000 permutation runs, respectively. The classification accuracy with true labels and the 95th percentile of empirical accuracy distribution are plotted in solid red line and dashed red line, respectively. Therefore, the classification accuracies in NCAβ+, MCIAβ+ and AD Aβ+ subjects are statistically significant at p=0.05 level. Figure S2.

The structure of the target compounds were confirmed using 1H NMR, 13C NMR, HRMS and FT-IR spectroscopy. The precise structure of (E)-N2,N2-dimethyl-6-styryl-1,3,5-triazine-2,4-diamine and (E)-N-(4-(dimethylamino)-6-styryl-1,3,5-triazin-2-yl) acetamide were analyzed using single-crystal X-ray diffraction. The molecular structures were further calculated using density functional theory (DFT), which were compared with the X-ray diffraction value. The results of the conformational analysis indicate that the molecular structures optimized by DFT were consistent with the crystal structures determined by single crystal X-ray diffraction. In addition, the molecular electrostatic potential and frontier molecular orbitals of the title compounds were further investigated by DFT, and some physicochemical properties of the compounds are revealed.

description: We present the GALEX UV photometry of the elliptical galaxies in Abell clusters at moderate redshifts (z < 0.2) for the study of the look-back time evolution of the UV upturn phenomenon. The brightest elliptical galaxies (M_r < -22) in 12 remote clusters are compared with the nearby giant elliptical galaxies of comparable optical luminosity in the Fornax and Virgo clusters. The sample galaxies presented here appear to be quiescent without signs of massive star formation or strong nuclear activity, and show smooth, extended profiles in their UV images indicating that the far-UV (FUV) light is mostly produced by hot stars in the underlying old stellar population. Compared to their counterparts in nearby clusters, the FUV flux of cluster giant elliptical galaxies at moderate redshifts fades rapidly with ~ 2 Gyrs of look-back time, and the observed pace in FUV - V color evolution agrees reasonably well with the prediction from the population synthesis models where the dominant FUV source is hot horizontal-branch stars and their progeny. A similar amount of color spread (~ 1 mag) in FUV - V exists among the brightest cluster elliptical galaxies at z ~ 0.1, as observed among the nearby giant elliptical galaxies of comparable optical luminosity.

description: The present thesis attempts a clarification of of the Aristotelian definition of the soul, De Anima II 1, 412b4-5, starting from a critical dispute with the theory of Abraham Bos, concerning the 'instrumental' character of the soul. By analysing the whole Aristotelian Corpus and by citing a variety of passages, it thoroughly studies the expressions σώμα φυσικόν, κοινόν τι, οργανικόν, πρώτη εντελέχεια, that are included in the definition of the soul, demonstrating that is is not an elusive or a general one, as it has traditionally been advocated, but it delineates the primary soul, the nutritive, attesting the Stagerit's preference for the simplest and more economical definitions

description: The thesis is rooted in the role of culture in the social and political reality. For that reason presented the Cultural Theory in modern intellectuals, compared with concepts of identity and diversity, identified by religion and the theory of Theatre Education. Thus supported the educational and social research which is conducted using the research-action, with the following hypothesis:if a cultural product, like Theatre-pedagogic programs (TiE) can have an intervening social purpose in the cross-cultural communication and they are likely to shape perceptions and attitudes, as in the case of students towards different religious. The research data and the conclusions obtained, evaluated, assessed and support proposals in which culture can have a role in the social change and also religious education should be compulsory but in an intercultural education

description: Laser spectroscopy of the $^{\mathrm{229m}}$Th nuclear clock transition is necessary for the future construction of a nuclear-based optical clock. Precision laser sources with broad spectral coverage in the vacuum ultraviolet are needed for this task. Here, we present a tunable vacuum-ultraviolet frequency comb based on cavity-enhanced seventh-harmonic generation. Its tunable spectrum covers the current uncertainty range of the $^{\mathrm{229m}}$Th nuclear clock transition.

description: We study exactly both the ground-state fidelity susceptibility and bond-bond correlation function in the Kitaev honeycomb model. Our results show that the fidelity susceptibility can be used to identify the topological phase transition from a gapped A phase with Abelian anyon excitations to a gapless B phase with non-Abelian anyon excitations. We also find that the bond-bond correlation function decays exponentially in the gapped phase, but algebraically in the gapless phase. For the former case, the correlation length is found to be $1/ξ=2\sinh^{-1}[\sqrt{2J_z -1}/(1-J_z)]$, which diverges around the critical point $J_z=(1/2)^+$.

description: We calculate $\partialμ/\partial n$ in extrinsic graphene as a function of carrier density $n$ at zero temperature by obtaining the electronic self-energy within the Hartree-Fock approximation. The exchange-driven Dirac-point logarithmic singularity in the quasiparticle velocity of intrinsic graphene disappears in the extrinsic case. The calculated renormalized $\partialμ/\partial n$ in extrinsic graphene has the same qualitative $n^{-\frac12}$ density dependence as the inverse bare density of states with a 20% enhancement from the corresponding bare value, a relatively weak effect compared to the corresponding parabolic-band case.

description: We use 9.5-yr of BiSON Sun-as-a-star data to search for dependence of solar-cycle parameter changes on the angular degree, l, of the data. The nature of the Sun-as-a-star observations is such that for changes measured at fixed frequency, or for changes averaged across the same range in frequency, any l dependence present carries information on the latitudinal distribution of the agent (i.e., the activity) responsible for those changes. We split the 9.5-yr timeseries into contiguous 108-d pieces, and determine mean changes in the damping of, power in, and energy supplied to the modes through the solar cycle. We also apply a careful correction to account for the deleterious effects of the ground-based BiSON window function on the results. From our full analysis we obtain a marginally significant result for the damping parameter, where the mean change is found to be weakest at l=0. The other parameters show hints of some dependence in l. Our main conclusion is that the mean fractional solar-cycle change in the l=0 damping rates is approximately 50 % smaller than was previously assumed. It had been common practice to use an average over all low-l modes; our downward revision of the radial-mode value has implications for comparisons with models of the global solar cycle changes, which are usually based on a spherically symmetric geometry.

description: Σκοπός της μελέτης : Η διερεύνηση του ρόλου και της σημασίας του Εγκεφαλικού Νατριουρητικού Πεπτιδίου (ΝΤ-proBNP) και της Ασύμμετρης Διμεθυλαργινίνης (ΑDΜΑ) για την εκτίμηση του κινδύνου εμφάνισης, τη διάγνωση και την παρακολούθηση της Πνευμονικής Αρτηριακής Υπέρτασης σε ασθενείς με Συστηματική Σκλήρυνση (ΣΣΠΑΥ). Μέθοδοι : Στη μελέτη συμμετείχαν 66 ασθενείς με ΣΣ, οι οποίοι υποβλήθηκαν σε ηχωκαρδιογράφημα καρδιάς και ιστικό DOPPLER, εργαστηριακό έλεγχο ρουτίνας και εξάλεπτη δοκιμασία βάδισης (6ΜWΤ). Ο προσδιορισμός των επιπέδων ΝΤ-proBNP και της ΑDΜΑ έγινε με ELISA. Αποτελέσματα: Η διάγνωση της ΣΣΠΑΥ (συστολική πίεση πνευμονικής αρτηρίας -SPAP > 40 mmHg) τέθηκε σε 24 ασθενείς. Οι ασθενείς με ΣΣΠΑΥ εμφάνισαν αυξημένη διάμετρο του αριστερού κόλπου, αυξημένο δείκτη μυοκαρδιακής απόδοσης της δεξιάς κοιλίας (ΔΚ), αυξημένο λόγο του κύματος της πρώιμης διαστολικής πλήρωσης στους διαμιτροειδικής ροής (κύμα Ε), προς τη μέγιστη πρώιμη διαστολική ταχύτητα κίνησης Ε/Εm της αριστερής κοιλίας (ΑΚ) στο ιστικό DOPPLER και μείωση της τιμής του κύματος Εm της ΔΚ. Στην ίδια ομάδα ασθενών η συγκέντρωση στο πλάσμα του ΝΤ-proBNP και της ADMA ήταν στατιστικά σημαντικά υψηλότερες σε σχέση με τους σκληροδερμικούς ασθενείς χωρίς ΠΑΥ. Τα επίπεδα του ΝΤ-proBNP συσχετίσθηκαν θετικά με τη SPAP και το λόγο των ταχυτήτων Ε/Εm της (ΑΚ) και αρνητικά με την απόσταση που διανύουν οι ασθενείς κατά το 6MWT. Τα επίπεδα της ADMA εμφάνισαν επίσης αρνητική συσχέτιση με την απόσταση του 6MWT. Τα επίπεδα του ΝΤ-proBNP και η διάμετρος του αριστερού κόλπου βρέθηκαν να αποτελούν ανεξάρτητους προγνωστικούς δείκτες για την πιθανότητα διάγνωσης ΣΣΠΑΥ στους ασθενείς της μελέτης. Συμπέρασμα : Οι βιοχημικοί και ηχωκαρδιογραφικοί δείκτες μπορούν να χρησιμοποιηθούν συνδυαστικά για την παρακολούθηση ομάδων ασθενών υψηλού κινδύνου για την εμφάνιση Πνευμονικής Υπέρτασης, όπως οι ασθενείς με σκληρόδερμα

description: We propose an algorithmic approach for synthesizing linear hybrid automata from time-series data. Unlike existing approaches, our approach provides a whole family of models. Each model in the family is guaranteed to capture the input data up to a precision error ε, in the following sense: For each time series, the model contains an execution that is ε-close to the data points. Our construction allows to effectively choose a model from this family with minimal precision error ε. We demonstrate the algorithm's efficiency and its ability to find precise models in two case studies.

Query complexity for searching multiple marked states from an unsorted database

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: An important and usual problem is to search all states we want from a database with a large number of states. In such, recall is vital. Grover's original quantum search algorithm has been generalized to the case of multiple solutions, but no one has calculated the query complexity in this case. We will use a generalized algorithm with higher precision to solve such a search problem that we should find all marked states and show that the practical query complexity increases with the number of marked states. In the end we will introduce an algorithm for the problem on a ``duality computer'' and show its advantage over other algorithms.

description: We give a simple geometric explanation for the similarity transformation mapping one-dimensional conformal mechanics to free-particle system. Namely, we show that this transformation corresponds to the inversion of the Klein model of Lobachevsky space (non-compact complex projective plane). We also extend this picture to the N=2k superconformal mechanics described in terms of Lobachevsky superspace.
