description: A linear stability analysis of the hydrodynamic equations of a model for confined quasi-two-dimensional granular gases is carried out. The stability analysis is performed around the homogeneous steady state (HSS) reached eventually by the system after a transient regime. In contrast to previous studies (which considered dilute or quasielastic systems), our analysis is based on the results obtained from the inelastic Enskog kinetic equation, which takes into account the (nonlinear) dependence of the transport coefficients and the cooling rate on dissipation and applies to moderate densities. As in earlier studies, the analysis shows that the HSS is linearly stable with respect to long enough wavelength excitations.

A transmission system for DPCM encoded monochrome images over a noisy channel
Creators: name: Chi, Sinclair
Publisher: name: University of British Columbia
Year: 2009

description: Due to the high correlation of neighbouring pixel values of a digital image, DPCM picture transmission has been a well investigated area of image compression. DPCM has found its way into standards such as JPEG and MPEG which have revolutionized the multimedia industry. However, because of the high noise sensitivity of DPCM compressed images, techniques must be developed to reduce the disturbing effects of channel errors. Hence, a DPCM image transmission system over a binary symmetric channel is studied, along with techniques used to improve picture quality. Two concepts which are the foci of the investigation are joint source/channel decoding (JSCD) and post-processing. The DPCM encoded image usually exhibits some residual redundancy. Thus the encoded image can be modeled as a first-order Markov model, and a bit error rate minimizing decoder takes advantage of the source statistics to correct errors. This is a type of constrained joint source/ channel decoding, and does not use added redundancy in the form of FEC to improve picture quality. Usually, side information consisting of source statistics need to be transmitted to the decoder. It is found that an iterative JSCD system which needs no side information has the same error performance as a system which requires error free transmission of the source statistics, but has a larger decoding delay. Furthermore, the JSCD system was generalized to one using a second-order Markov model and the improvement was found to be negligible. JSCD decoding at a very high probability of error, does not correct all of the channel errors; and there remains some very noticeable errors. Post-processing techniques have been applied to corrupted DPCM images and thus it is proposed that the similar techniques be applied to JSCD DPCM images. A thresholding technique is developed to locate the errors and then correct the erroneous symbols. Symbol correction methods which make use of source statistics are compared to a correction technique based solely on the analysis of the decoded DPCM image. Subjective and objective results are presented with the use of the output images and signal-to-noise ratio graphs. These measures demonstrate that the proposed system of a concatenated source/channel decoder followed by a post-processor improves a noise corrupted DPCM image quite effectively.

description: We present a novel method for computing the nonperturbative kinetic term of the gluon propagator from an exactly solvable ordinary differential equation, whose origin is the fundamental Slavnov-Taylor identity satisfied by the three-gluon vertex, evaluated in a special kinematic limit. The main ingredients comprising the solution are a well-known projection of the three-gluon vertex, simulated on the lattice, and a particular derivative of the ghost-gluon kernel, whose approximate form is derived from a standard Schwinger-Dyson equation. Crucially, the physical requirement of a pole-free answer determines completely the form of the initial condition, whose value is calculated from a specific integral containing the same ingredients as the solution itself. This outstanding feature fixes uniquely, at least in principle, the form of the kinetic term, once the ingredients of the differential equation have been accurately evaluated. Furthermore, in the case where the gluon propagator has been independently accessed from the lattice, this property leads to the unambiguous extraction of the momentum-dependent effective gluon mass. The practical implementation of this method is carried out in detail, and the required approximations and theoretical assumptions are duly highlighted. The systematic improvement of this approach through the detailed computation of one of its pivotal components is briefly outlined.

description: Phase self-calibration (or selfcal) is an algorithm often used in the calibration of interferometric observations in astronomy. Although a powerful tool, this algorithm presents strong limitations when applied to data with a low signal-to-noise ratio. We analyze the artifacts that the phase selfcal algorithm produces when applied to extremely noisy data. We show how the phase selfcal may generate a spurious source in the sky from a distribution of completely random visibilities. This spurious source is indistinguishable from a real one. We numerically and analytically compute the relationship between the maximum spurious flux density generated by selfcal from noise and the particulars of the interferometric observations. Finally, we present two simple tests that can be applied to interferometric data for checking whether a source detection is real or whether the source is an artifact of the phase self-calibration algorithm.

description: Talk given to the northern chapter of the Royal Society of Biology on 4 March 2021. Summary MammalWeb works with citizen scientists to deploy motion-sensing “camera traps” to capture wildlife images. The photos produced make up a valuable dataset from which experts can infer a better understanding of the diversity and distribution of wildlife. Started in 2014 at Durham University with citizen scientists across North-East England, MammalWeb is now an international network with contributions from individuals and organisations across Europe. Collectively, this effort has conducted more than 180 years worth of observations yielding 1.5+ million images. Anyone can submit camera trap images or aid in their classification from the MammalWeb website (@MammalWeb on Twitter, email info@mammalweb.org). In this event, Dr Pen-Yuan Hsing, co-founder of MammalWeb, will speak to the development of MammalWeb, its scientific implications, and how it facilitates civic engagement by participants.

description: The paper shows that while tourism has grown over the past few decades and has made a significant contribution to Tanzania’s exports, Tanzania’s economy and Tanzania’s labour market, Tanzania’s tourism sector could have been more successful. This claim is supported by the fact that Tanzania has a greater number of natural wonders than its competitors, greater potential market and it features more prominently than other destinations in the packages offered by tour operators around the world. The paper further argues that while the tourism sector could be more successful and attract more tourists, there is a trade-off between the economic dividends and the environmental problems that a thriving tourism sector could generate. The key policy implication of the present paper is that Tanzania’s tourism sector should be developed in a sustainable way. By failing to do so and by damaging the environment, the tourism sector could undermine its own sustainability.

description: Οι ιοί του γένους Polerovirus αποτελούν από τους πλέον διαδεδομένους παγκοσμίως και προσβάλλουν οικονομικώς σημαντικές καλλιέργειες όπου προκαλούν σημαντικές απώλειες στην παραγωγή. Στην παρούσα μελέτη αναπτύχθηκε μια μέθοδος γενικής ανίχνευσης των Polero-ιών η οποία βασίζεται στην χρησιμοποίηση εκφυλισμένων εκκινητών που υβριδοποιούνται στην περιοχή της RdRp σε συνδυασμό με μία RT-PCR με κλιμακωτή θερμοκρασία υβριδοποίησης. Το προβλεπόμενο προϊόν των 593bp μπορεί να αλληλουχηθεί απευθείας για την απόκτηση μιας αρχικής εικόνας σχετικά με την κατάταξη των απομονώσεων. Η μέθοδος που αναπτύχθηκε είναι ικανή να ανιχνεύσει γρήγορα και αξιόπιστα απομονώσεις τουλάχιστον 10 διαφορετικών μελών του γένους.Επίσης, πραγματοποιήθηκε μερικός χαρακτηρισμός ενός Polero-ιού που απομονώθηκε από φυτά πιπεριάς που εμφάνιζαν συμπτώματα ίκτερου. Αλληλούχιση τμήματος 1630nt του γονιδιώματος της απομόνωσης αυτής και φυλογενετικές αναλύσεις των προβλεπόμενων αμινοξικών αλληλουχιών της RdRp, CP και MP, έδειξαν την σαφή διαφοροποίησή της από τα υπόλοιπα μέλη της οικογένειας Luteoviridae. Τα αποτελέσματα αυτά οδήγησαν στην πρόταση της δημιουργίας ενός νέου, υπό ένταξη, είδους ιού στο γένος Polerovirus της οικογένειας Luteoviridae το οποίο θα περιλαμβάνει τη νεοευρεθείσα απομόνωση με το όνομα ιός του ίκτερου της πιπεριάς – Pepper yellows virus-PeYV.
description: Viruses of the genus Polerovirus are amongst the most commonly found plant virus worldwide and infect economically important crops resulting in severe yield losses. In this study a generic detection method of poleroviruses was developed using degenerate primers which target the RdRp region of the genome. The predicted amplicon of 593bp can be directly sequenced in order to obtain initial information about the classification of the isolates. The method developed detected fast and reliably isolates of at least 10 different members of the genus.Also, a polerovirus isolate from pepper plants exhibiting yellowing symptoms was partially characterized. Comparison of a 1630bp sequence of this isolate’s genome along with phylogenetic analysis of the predicted amino acid sequences corresponding to the RdRp, CP and MP regions, revealed a clear distinction from other members of the family Luteoviridae. From the available results we consider this as a new tentative virus species of the genus Polerovius in the family Luteoviridae and for which we propose the name of Pepper yellows virus-PeYV.

description: We use the parabolic wave equation to study the propagation of x-rays in tapered waveguides by numercial simulation and optimization. The goal of the study is to elucidate how beam concentration can be best achieved in x-ray optical nanostructures. Such optimized waveguides can e.g. be used to investigate single biomolecules. Here, we compare tapering geometries, which can be parametrized by linear and third-order (Bezier-type) functions and can be fabricated using standard e-beam litography units. These geometries can be described in two and four-dimensional parameter spaces, respectively. In both geometries, we observe a rugged structure of the optimization problem's ``gain landscape''. Thus, the optimization of x-ray nanostructures in general will be a highly nontrivial optimization problem.

description: Schottky photodetectors are attractive for CMOS-compatible photonic integrated circuits, but the trade-off between photon absorption and hot carrier emission often compromises the detection fidelity and sensitivity. Here, we report a hybridization-based waveguiding effect that can improve the sensitivity of guided-wave Schottky detection by >200x. By hybridizing the supermodes guided by asymmetrical coupled plasmonic nanostructures, light-matter-interaction can be significantly enhanced even if the thickness of the light absorbing region is only a few nanometers, thus allowing the absorption and emission efficiencies to be simultaneously optimized for the first time. Using amorphous-based active junction with absorbing volume of only 0.031 μm3, our detectors demonstrate record experimental sensitivity of -55 dBm, approaching that of crystalline-based Ge counterparts with >36x larger absorption region. The ability to maximize field overlap within small device volume and improve photodetection fidelity without using crystalline materials pave the way towards improved back-end-of-line interconnection, single photon detection, and 2D optoelectronics.

description: The Left-Right symmetric extension of the Standard Model with Higgs isospin triplets can provide neutrino masses via a TeV scale seesaw mechanism. The doubly charged Higgs bosons H^{\pm\pm}_L and H^{\pm\pm}_R induce lepton flavour violating decays τ^\pm \to lll at tree-level via a coupling which is related to the Maki-Nakagawa-Sakata matrix (V_{\rm MNS}). We study the magnitude and correlation of τ^\pm \to lll and μ\to eγwith specific assumptions for the origin of the large mixing in V_{\rm MNS} while respecting the stringent bound for μ\to eee. It is also shown that an angular asymmetry for τ^\pm \to lll is sensitive to the relative strength of the H^{\pm\pm}_L and H^{\pm\pm}_R mediated contributions and provides a means of distinguishing models with doubly charged Higgs bosons.

description: From a physical/dynamical system perspective, the potential well represents the proportional mass of points that escape the neighbourhood of a given point. In the last 20 years, several works have shown the importance of this quantity to obtain precise approximations for several recurrence time distributions in mixing stochastic processes and dynamical systems. Besides providing a review of the different scaling factors used in the literature in recurrence times, the present work contributes with two new results: (1) for $ϕ$-mixing and $ψ$-mixing processes, we give a new exponential approximation for hitting and return times using the potential well as scaling parameter. The error terms are explicit and sharp. (2) We analyse the uniform positivity of the potential well.

Η εργασία παρουσιάζει συνοπτικά τις γνωστότερες θεωρητικές προσεγγίσεις για τα αναλυτικά προγράμματα, κυρίως όμως «αντλεί» θεωρητικά από τον σχεδιασμό του Αναλυτικού Προγράμματος όπως αρθρώνεται από τον τον βραζιλιάνο παιδαγωγό Paulo Freire. Έχοντας, επίσης, ως αφετηρία τη μαρξιστική οπτική για την εκπαίδευση και τον εμπλουτισμό της από το ρεύμα της Κριτικής Θεωρίας και της Κριτικής Παιδαγωγικής, αλλά και τις βασικές αρχές της Αντιρατσιστικής Εκπαίδευσης, καταλήγει σε μια σειρά προτάσεων για ένα ανοικτό Αναλυτικό Πρόγραμμα και μια σειρά δράσεων συμπληρωματικών της σχολικής ζωής που, εν τέλει, συνδυαστικά στοχεύουν στον «γραμματισμό και συνειδητοποίηση» των μαθητών/τριών του «Οδυσσέα».
description: The present paper treats a proposal for a curriculum for the voluntary school “Odysseus”. This school has operated on a voluntary base since 1997, offering gratis courses of Hellenic language to thousands of immigrants (more than five thousands), whereas more than two hundred educators (primary and secondary school teachers as well as academics) have offered their services.Furthermore, the school has run courses on PC Basics, English language and dancing and inspired the formation of a multiethnic theatre group, which has already put on the stage five plays with great success. The paper presents synoptically the most known theories on school curriculums, yet, its theoretical approach mainly draws from the Brazilian pedagogist’s, Paulo Freire, planning of curriculum. Moreover, originating from the Marxist theory of education and its enrichment by the movements of Critical Theory and Critical Pedagogy, as well as the principles of the Antiracist Education, the paper proposes an open School Curriculum and a series of actions, which complement school life. Their combination aims at the “literacy and awareness” of the students of “Odysseus”.

description: We show that the Wilson loop operator for SU(N) Yang-Mills gauge connection is exactly rewritten in terms of conserved gauge-invariant magnetic and electric currents through a non-Abelian Stokes theorem of the Diakonov-Petrov type. Here the magnetic current originates from the magnetic monopole derived in the gauge-invariant way from the pure Yang--Mills theory even in the absence of the Higgs scalar field, in sharp contrast to the 't Hooft-Polyakov magnetic monopole in the Georgi-Glashow gauge-Higgs model. The resulting representation indicates that the Wilson loop operator in fundamental representations can be a probe for a single magnetic monopole irrespective of $N$ in SU(N) Yang-Mills theory, against the conventional wisdom. Moreover, we show that the quantization condition for the magnetic charge follows from the fact that the non-Abelian Stokes theorem does not depend on the surface chosen for writing the surface integral. The obtained geometrical and topological representations of the Wilson loop operator have important implications to understanding quark confinement according to the dual superconductor picture.

description: Visual quality evaluation is one of the challenging basic problems in image processing. It also plays a central role in the shaping, implementation, optimization, and testing of many methods. The existing image quality assessment methods focused on images corrupted by common degradation types while little attention was paid to color quantization. This in spite there is a wide range of applications requiring color quantization assessment being used as a preprocessing step when color-based tasks are more efficiently accomplished on a reduced number of colors. In this paper, we propose and carry-out a quantitative performance evaluation of nine well-known and commonly used full-reference image quality assessment measures. The evaluation is done by using two publicly available and subjectively rated image quality databases for color quantization degradation and by considering suitable combinations or subparts of them. The results indicate the quality measures that have closer performances in terms of their correlation to the subjective human rating and show that the evaluation of the statistical performance of the quality measures for color quantization is significantly impacted by the selected image quality database while maintaining a similar trend on each database. The detected strong similarity both on individual databases and on databases obtained by integration provides the ability to validate the integration process and to consider the quantitative performance evaluation on each database as an indicator for performance on the other databases. The experimental results are useful to address the choice of suitable quality measures for color quantization and to improve their future employment.

description: The nonlinear integral equation P(x)=\int_alpha^beta dy w(y) P(y) P(x+y) is investigated. It is shown that for a given function w(x) the equation admits an infinite set of polynomial solutions P(x). For polynomial solutions, this nonlinear integral equation reduces to a finite set of coupled linear algebraic equations for the coefficients of the polynomials. Interestingly, the set of polynomial solutions is orthogonal with respect to the measure x w(x). The nonlinear integral equation can be used to specify all orthogonal polynomials in a simple and compact way. This integral equation provides a natural vehicle for extending the theory of orthogonal polynomials into the complex domain. Generalizations of the integral equation are discussed.

description: We investigate the relation between the girth and the guaranteed error correction capability of $γ$-left regular LDPC codes when decoded using the bit flipping (serial and parallel) algorithms. A lower bound on the number of variable nodes which expand by a factor of at least $3 γ/4$ is found based on the Moore bound. An upper bound on the guaranteed correction capability is established by studying the sizes of smallest possible trapping sets.

description: We present a density functional scheme for calculating the pair density (PD) by means of the correlated wave function. This scheme is free from both of problems related to PD functional theory, i.e., (a) the need to constrain the variational principle to $N$-representable PDs and (b) the development of a kinetic energy functional. By using the correlated wave function, the searching region for the ground-state PD is substantially extended as compared with our previous theory[Physica B \textbf{372} (2007), in press]. The variational principle results in the simultaneous equations that yield the best PD beyond the previous theory, not to mention the Hartree-Fock approximation.

description: The bounds on concurrence of the superposition state in terms of those of the states being superposed are studied in this paper. The bounds on concurrence are quite different from those on the entanglement measure based on von Neumann entropy (Phys. Rev. Lett. 97, 100502 (2006)). In particular, a nonzero lower bound can be provided if the states being superposed are properly constrained.

Activity Complexes and A Prominent Poleward Surge During Solar Cycle 24

description: Long-lasting activity complexes (ACs), characterised as a series of closely located, continuously emerging solar active regions (ARs), are considered generating prominent poleward surges from observations. The surges lead to significant variations of the polar field, which are important for the modulation of solar cycles. We aim to study a prominent poleward surge during solar cycle 24 on the southern hemisphere, and analyse its originating ACs and the effect on the polar field evolution. We automatically identify and characterize ARs based on synoptic magnetograms from the Solar Dynamic Observatory. We assimilate these ARs with realistic magnetic configuration into a surface flux transport model, and simulate the creation and migration of the surge. Our simulations well reproduce the characteristics of the surge and show that the prominent surge is mainly caused by the ARs belonging to two ACs during Carrington Rotations 2145-2159 (December 2013-January 2015). The surge has a strong influence on the polar field evolution of the southern hemisphere during the latter half of cycle 24. Without the about one-year-long flux emergence in the form of ACs, the polar field around the cycle minimum would have remained at a low level and even reversed to the polarity at cycle 23 minimum. Our study also shows that the long-lived unipolar regions due to the decay of the earlier emerging ARs cause an intrinsic difficulty of automatically identifying and precisely quantifying later emerging ARs in ACs.

description: We study the properties of random walks on complex trees. We observe that the absence of loops reflects in physical observables showing large differences with respect to their looped counterparts. First, both the vertex discovery rate and the mean topological displacement from the origin present a considerable slowing down in the tree case. Second, the mean first passage time (MFPT) displays a logarithmic degree dependence, in contrast to the inverse degree shape exhibited in looped networks. This deviation can be ascribed to the dominance of source-target topological distance in trees. To show this, we study the distance dependence of a symmetrized MFPT and derive its logarithmic profile, obtaining good agreement with simulation results. These unique properties shed light on the recently reported anomalies observed in diffusive dynamical systems on trees.

description: This work introduces a new set of orbital elements to fully represent the zonal harmonics problem around an oblate celestial body. This new set of orbital elements allows to obtain a complete linear system for the unperturbed problem and, in addition, a complete polynomial system when considering the perturbation produced by the zonal harmonics from the gravitational force of an oblate celestial body. These orbital elements present no singularities and are able to represent any kind of orbit, including elliptic, parabolic and hyperbolic orbits. In addition, an application to this formulation of the Poincaré-Lindstedt perturbation method is included to obtain an approximate first order solution of the problem for the case of the J2 perturbation.

description: The radiative neutron capture cross section of 207Pb has been measured at the CERN neutron time of flight installation n_TOF using the pulse height weighting technique in the resolved energy region. The measurement has been performed with an optimized setup of two C6D6 scintillation detectors, which allowed us to reduce scattered neutron backgrounds down to a negligible level. Resonance parameters and radiative kernels have been determined for 16 resonances by means of an R-matrix analysis in the neutron energy range from 3 keV to 320 keV. Good agreement with previous measurements was found at low neutron energies, whereas substantial discrepancies appear beyond 45 keV. With the present results, we obtain an s-process contribution of 77(8)% to the solar abundance of 207Pb. This corresponds to an r-process component of 23(8)%, which is important for deriving the U/Th ages of metal poor halo stars.
