description: Σκοπός Αξιολόγηση της εμφρακτικής ικανότητας διαφορετικών κύριων κώνων γουταπέρκας με εμβαδομετρική ανάλυση. Υλικά και μέθοδοι 60 κάτω προγόμφιοι με ευθείς ριζικούς σωλήνες προπαρασκευάστηκαν με μηχανοκίνητα εργαλεία ProTaper ® και διαχωρίστηκαν σε τέσσερις ομάδες. Οι τρεις πρώτες εμφράχθηκαν με πλάγια συμπύκνωση, χρησιμοποιώντας φύραμα ΑΗ-26 και κύριο κώνο γουταπέρκας: .02 (Α), .04 (Β), μη τυποποιημένο F- Medium (Γ), ενώ η τέταρτη με φύραμα ΑΗ-26 και μονό κώνο γουταπέρκας του συστήματος ProTaper (Δ). Το ποσοστό της γουταπέρκας και του φυράματος υπολογίστηκε με τη βοήθεια λογισμικού σε οριζόντιες τομές του ακρορριζικού τριτημορίου. Αποτελέσματα Σε κάθε επίπεδο τομής, η κατανομή των εμφρακτικών υλικών δεν διέφερε σημαντικά (P>0.05) μεταξύ των ομάδων Α, Β, Γ, Δ. Κατά τη συνολική εκτίμηση των τομών, προέκυψε σημαντική διαφορά (P<0.05) υπέρ της ομάδας Δ έναντι των Α, Β, Γ ως προς το ποσοστό της γουταπέρκας. Συμπεράσματα Αν και η τεχνική του μονού κώνου εμφάνισε κάποιου βαθμού υπεροχή, καμία από τις τεχνικές δεν οδήγησε σε ερμητική έμφραξη του ριζικού σωλήνα.
description: Aim Evaluation of the sealing ability of different master gutta-percha cones by area-metric analysis of obturation. Materials and methods Sixty mandibular premolars with straight canals were instrumented using System ProTaper rotary files ® in a crown-down technique and separated in four groups. The first three were obturated with lateral condensation, using AH-26 sealer and master gutta-percha cone: .02 (group A), .04 (group B) and non-standardized F- Medium (group C), while the fourth was obturated using AH-26 sealer and single gutta-percha cone of System ProTaper (group D). The percentage of gutta-percha and sealer filled area was calculated in horizontal sections of the apical portion of each root, using image-analysis program. Results At each level of section, the distribution of filling materials was not significantly different (P>0.05) between groups A, B, C, D. Taking all levels in account, however, group D had more gutta-percha obturated area than groups A, B and C (P<0.05). Conclusion Although the single cone technique presented a certain degree of superiority, none of the techniques was able to provide complete obturation of the root canal.

description: We develop a recurrent gamma belief network (rGBN) for radar automatic target recognition (RATR) based on high-resolution range profile (HRRP), which characterizes the temporal dependence across the range cells of HRRP. The proposed rGBN adopts a hierarchy of gamma distributions to build its temporal deep generative model. For scalable training and fast out-of-sample prediction, we propose the hybrid of a stochastic-gradient Markov chain Monte Carlo (MCMC) and a recurrent variational inference model to perform posterior inference. To utilize the label information to extract more discriminative latent representations, we further propose supervised rGBN to jointly model the HRRP samples and their corresponding labels. Experimental results on synthetic and measured HRRP data show that the proposed models are efficient in computation, have good classification accuracy and generalization ability, and provide highly interpretable multi-stochastic-layer latent structure.

description: High resolution HST/ACS images of the galaxy cluster RX J1347-1145 have enabled us to identify several new multiple image candidates in the cluster, including a 5 image system with a central image. The multiple images allow us to construct an accurate 2-dimensional mass map of the central part of the cluster. The modelling of the cluster mass includes the most prominent cluster galaxies modelled as truncated isothermal spheres and a smooth halo component that is described with 2 parametric profiles. The mass reconstruction is done using a Markov chain Monte Carlo method that provides us with a total projected mass density as well as estimates for the parameters of interest and their respective errors. The mass profile is in reasonable agreement with previous mass estimates based on the X-ray emission from the hot intra-cluster gas, however the X-ray mass estimates are systematically lower than what we obtain with gravitational lensing.

description: We study electron correlation driven superconductivity on a decorated honeycomb lattice (DHL), which has a low-energy flat band. On doping, we find singlet superconductivity with extended-s, extended-d and f-wave symmetry mediated by magnetic exchange. f-wave singlet pairing is enabled by the lattice decoration. The critical temperature is predicted to be significantly higher than on similar lattices lacking flat bands. We discuss how high-temperature superconductivity could be realized in the DHL materials such as Rb3TT. 2 H2O and Mo3S7(dmit)3.

description: We reconsider and update the QCD light-cone sum rules for $B\to π$ form factors. The gluon radiative corrections to the twist-2 and twist-3 terms in the correlation functions are calculated. The $\bar{MS}$ $b$-quark mass is employed, instead of the one-loop pole mass used in the previous analyses. The light-cone sum rule for $f^+_{Bπ}(q^2)$ is fitted to the measured $q^2$-distribution in $B\to πl ν_l$, fixing the input parameters with the largest uncertainty: the Gegenbauer moments of the pion distribution amplitude. For the $B\to π$ vector form factor at zero momentum transfer we predict $f^+_{Bπ}(0)= 0.26^{+0.04}_{-0.03}$. Combining it with the value of the product $|V_{ub}f^+_{Bπ}(0)|$ extracted from experiment, we obtain $|V_{ub}|=(3.5\pm 0.4\pm 0.2\pm 0.1) \times 10^{-3}$. In addition, the scalar and penguin $B\to π$ form factors $f^0_{Bπ}(q^2)$ and $f^T_{Bπ}(q^2)$ are calculated.

description: In this two-part series of papers, a generalized non-orthogonal amplify and forward (GNAF) protocol which generalizes several known cooperative diversity protocols is proposed. Transmission in the GNAF protocol comprises of two phases - the broadcast phase and the cooperation phase. In the broadcast phase, the source broadcasts its information to the relays as well as the destination. In the cooperation phase, the source and the relays together transmit a space-time code in a distributed fashion. The GNAF protocol relaxes the constraints imposed by the protocol of Jing and Hassibi on the code structure. In Part-I of this paper, a code design criteria is obtained and it is shown that the GNAF protocol is delay efficient and coding gain efficient as well. Moreover GNAF protocol enables the use of sphere decoders at the destination with a non-exponential Maximum likelihood (ML) decoding complexity. In Part-II, several low decoding complexity code constructions are studied and a lower bound on the Diversity-Multiplexing Gain tradeoff of the GNAF protocol is obtained.

description: Classical novae result from thermonuclear explosions producing several $γ$-ray emitters which are prime targets for satellites observing in the MeV range. The early 511 keV gamma-ray emission depends critically on the $^{18}$F(p,$α$)$^{15}$O reaction rate which, despite many experimental and theoretical efforts, still remains uncertain. One of the main uncertainties in the $^{18}$F(p,$α$)$^{15}$O reaction rate is the contribution in the Gamow window of interference between sub-threshold $^{19}$Ne states and known broad states at higher energies. Therefore the goal of this work is to clarify the existence and the nature of these sub-threshold states. States in the $^{19}$Ne compound nucleus were studied at the Tandem-ALTO facility using the $^{19}$F($^3$He,t)$^{19}$Ne charge exchange reaction. Tritons were detected with an Enge Split-pole spectrometer while decaying protons or $α$-particles from unbound $^{19}$Ne states were collected, in coincidence, with a double-sided silicon strip detector array. Angular correlations were extracted and constraints on the spin and parity of decaying states established. The coincidence yield at $E_x$ = 6.29 MeV was observed to be high spin, supporting the conclusion that it is indeed a doublet consisting of high spin and low spin components. Evidence for a broad, low spin state was observed around 6 MeV. Branching ratios were extracted for several states above the proton threshold and were found to be consistent with the literature. R-matrix calculations show the relative contribution of sub-threshold states to the astrophysically important energy region above the proton threshold. The levels schemes of $^{19}$Ne and $^{19}$F are still not sufficiently well known and further studies of the analogue assignments are needed. The tentative broad state at 6 MeV may only play a role if the reduced proton width is large.

description: The formation of out-of-equilibrium patterns is a characteristic feature of spatially-extended, biodiverse, ecological systems. Intriguing examples are provided by cyclic competition of species, as metaphorically described by the `rock-paper-scissors' game. Both experimentally and theoretically, such non-transitive interactions have been found to induce self-organization of static individuals into noisy, irregular clusters. However, a profound understanding and characterization of such patterns is still lacking. Here, we theoretically investigate the influence of individuals' mobility on the spatial structures emerging in rock-paper-scissors games. We devise a quantitative approach to analyze the spatial patterns self-forming in the course of the stochastic time evolution. For a paradigmatic model originally introduced by May and Leonard, within an interacting particle approach, we demonstrate that the system's behavior - in the proper continuum limit - is aptly captured by a set of stochastic partial differential equations. The system's stochastic dynamics is shown to lead to the emergence of entangled rotating spiral waves. While the spirals' wavelength and spreading velocity is demonstrated to be accurately predicted by a (deterministic) complex Ginzburg-Landau equation, their entanglement results from the inherent stochastic nature of the system.These findings and our methods have important applications for understanding the formation of noisy patterns, e.g., in ecological and evolutionary contexts, and are also of relevance for the kinetics of (bio)-chemical reactions.

Year: 1993
Subjects: subject: Transportation Engineering

description: The objectives of this study were to determine average accident rates tor various categories of at-grade intersections and to identify intersections having high accident rates. This involved locating intersections at two or more state-maintained highways and determining the appropriate volumes to use as well as locating the accidents occurring at any given intersection.  A procedure was developed to allow tor the identification of intersections having high or critical accident rates. A list at the intersections of two or more state-maintained roadways was developed. A total of 6,707 intersections were included in the file. Using county, route and milepoint information, accident and volume data were associated with each intersection. Accident rates were calculated for each intersection. The rates are in terms of accidents per million entering vehicles (ACC/MV). Statewide average and critical accident rates were calculated by functional classification. Intersections having critical accident rates were then identified using both the typical procedure and a procedure which accounted for the regression-to-the-mean bias.

description: We study the effective dynamics of an open scalar field interacting with a strongly-coupled two-dimensional rotating CFT plasma. The effective theory is determined by the real-time correlation functions of the thermal plasma. We employ holographic Schwinger-Keldysh path integral techniques to compute the effective theory. The quadratic effective theory computed using holography leads to the linear Langevin dynamics with rotation. The noise and dissipation terms in this equation get related by the fluctuation-dissipation relation in presence of chemical potential due to angular momentum. We further compute higher order terms in the effective theory of the open scalar field. At quartic order, we explicitly compute the coefficient functions that appear in front of various terms in the effective action in the limit when the background plasma is slowly rotating. The higher order effective theory has a description in terms of the non-linear Langevin equation with non-Gaussianity in the thermal noise.

description: One objective of this study was to update the statistics related to alcohol-related accidents and arrests In Fayette County. The second objective was to include an analysis of speed-related accidents and citations.  The number of alcohol-related accidents in Fayette County has decreased over the past several years. The number of speed-related accidents has remained relatively constant Differences between the characteristics of all accidents and alcohol and speed-related accidents were noted. For example, there were higher percentages of alcohol and speed-related accidents involving a fixed object. Differences in driver characteristics, such as the high percentage of drivers in the 16 to 19 years of age category involved in speed-related accidents, were noted.  Alcohol and speeding arrest and citation data were analyzed. The number of DUI arrests, as well as the number of speeding citations, has increased in recent years. Comparisons were made between the arrest and citation data and the accident data. For example, differences by time of day were documented. The area of the county in which alcohol and speed-related accidents occurred as well as where DUI arrests occurred were summarized.  Characteristics of drivers with DUI arrests and speeding citations were summarized. Additional analyses were performed for drivers with more than one DUI arrest. This data show the type of driver prone to recidivism.

description: Hybrid Superconductor/Ferromagnet structures have been investigated recently to address the interplay between ferromagnetism and superconductivity. They also open up new routes for the investigation of out of equilibrium superconductivity. Here, we show how it is possible for out of equilibrium excitations produced in a superconducting thin film (S) to be localized in a ferromagnetic trap (F). Specifically, a ferromagnetic nano-volume in good contact with S represents a potential well for the quasiparticles (QPs) at the gap edge. As the superconducting proximity effect is highly suppressed in F, QPs get efficiently trapped and they share their energy with the free electrons in the trap. The electronic temperature Te in the trap can be increased by up to 60% from the bath temperature at 320 mK as measured by tunneling spectroscopy using a second junction.

description: Video facial expression recognition is useful for many applications and received much interest lately. Although some solutions give really good results in a controlled environment (no occlusion), recognition in the presence of partial facial occlusion remains a challenging task. To handle occlusions, solutions based on the reconstruction of the occluded part of the face have been proposed. These solutions are mainly based on the texture or the geometry of the face. However, the similarity of the face movement between different persons doing the same expression seems to be a real asset for the reconstruction. In this paper we exploit this asset and propose a new solution based on an auto-encoder with skip connections to reconstruct the occluded part of the face in the optical flow domain. To the best of our knowledge, this is the first proposition to directly reconstruct the movement for facial expression recognition. We validated our approach in the controlled dataset CK+ on which different occlusions were generated. Our experiments show that the proposed method reduce significantly the gap, in terms of recognition accuracy, between occluded and non-occluded situations. We also compare our approach with existing state-of-the-art solutions. In order to lay the basis of a reproducible and fair comparison in the future, we also propose a new experimental protocol that includes occlusion generation and reconstruction evaluation.
A semiotic approach for the teaching of energy: linking mechanical work and heat with the world of objects and events

description: In this study an effort is made to provide links between the world of physics (theoretical) model about energy transfer with the world of objects and events. Taking into account a holistic approach on energy based on conservation of energy principle and a semiotic approach based on the multimodality of teaching, it was investigated whether a ‘no contact, contact plus change’ pattern can signify in the material world the separation and the interaction between the physical systems and the changes within the systems. An analysis of a teacher’s actions from a physics lesson and a physics textbook concerning mechanical work and heat as mechanisms of energy transfer was made, identifying the no contact, contact + change pattern in speech, written text, bodily acts and inscriptions. It was shown that this semiotic schema has the potential to transfer the physics model about mechanical work and heat to the world of objects and events avoiding ambiguities that create conceptual blending between transformation and transfer of energy. In addition, illustrating the idea of change by movement for mechanical work (position change) and by haptic contact or different colours for heat (temperature change) might be of great importance in teaching activities about transfer of energy.

description: This review presents flavour related issues in the production and decays of heavy states at LHC, both from the experimental side and from the theoretical side. We review top quark physics and discuss flavour aspects of several extensions of the Standard Model, such as supersymmetry, little Higgs model or models with extra dimensions. This includes discovery aspects as well as measurement of several properties of these heavy states. We also present public available computational tools related to this topic.

The wetting problem of fluids on solid surfaces. Part 1: the dynamics of contact lines
Creators: name: Gouin, Henri
Publisher: name: arXiv
Year: 2008
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: The understanding of the spreading of liquids on solid surfaces is an important challenge for contemporary physics. Today, the motion of the contact line formed at the intersection of two immiscible fluids and a solid is still subject to dispute. In this paper, a new picture of the dynamics of wetting is offered through an example of non-Newtonian slow liquid movements. The kinematics of liquids at the contact line and equations of motion are revisited. Adherence conditions are required except at the contact line. Consequently, for each fluid, the velocity field is multivalued at the contact line and generates an equivalent concept of line friction but stresses and viscous dissipation remain bounded. A Young-Dupré equation for the apparent dynamic contact angle between the interface and solid surface depending on the movements of the fluid near the contact line is proposed.

The biooxidation and cyanidation of a refractory arsenical gold concentrate:
Creators: name: Jones, Lyn
Publisher: name: University of British Columbia
Year: 2009

description: A significant drawback to the application of biooxidation as a pretreatment for refractory gold concentrates is the problem of high cyanide consumption. The presence of cyanicides in biooxidized residues are commonly referred to in the literature, but specific mechanisms are not proposed. In this study, a four-stage continuous bench scale bioreactor apparatus was set up to generate a representative biooxidized product suitable for an extensive cyanidation study. In all, four biooxidation steady states were reached. Residence times ranged from 2 to 5 days, while temperature and pulp density remained constant at 35 °C and 20%, respectively. With the first two steady states, the primary stage pH was controlled at 1.8, whereas for the second two the pH was controlled at 1.5. Sulfide oxidation ranged from 70% to 93%. Cyanidation experiments were conducted on the final products, as well as on samples taken from the intermediate stages of the reactor. The solids were leached under varying conditions of pulp density, NaCN concentration, pH, temperature, and stirring speed. Gold extractions ranged from 46.1% to 95.6%. The sodium cyanide consumption varied from 2.70 to 12.07 kg/tonne-concentrate. Results indicated that the high cyanide consumption associated with this concentrate is the result of two separate reaction mechanisms: one forming thiocyanate (SCN") possibly from a reactive form of elemental sulfur, and the other forming hexacyanoferrates (Fe(CN)₆³⁻ and Fe(CN)₅⁴⁻) by decomposition of basic ferric sulfate precipitates. Cyanide use can be reduced by employing higher pulp densities, primary stage aeration, and shorter overall leach times.

description: A precise and stable timing system is necessary for high intensity proton accelerators such as the J-PARC. The original timing system, which was developed during the construction period of the J-PARC, has been working without major issues since 2006. After a decade of operation, the optical modules, which are key components for signal transfer, were discontinued already. Thus, the next-generation timing system for the J-PARC has been developed and built. The new system is designed to be compatible with the original system in terms of the operating principle. The new system utilizes modern high speed serial communication for the transfer of the clock, reference trigger, and type code. We describe the system configuration of the next-generation timing system and current status.

Analytical Study of House Price Prediction Models
Creators: name: Gauri Mhatre, Prof.Gauri Ansurkar
Publisher: name: Zenodo
Year: 2024

description: House Price Prediction is commonly used to evaluate the changes in price of houses. Since housing price is strongly corresponding to other factors such as location, area, population, it requires other information apart from HPP to predict individual housing price. Researches has stated that changes in house prices are due to concern of for house owners and the real estate market. Large numbers of paper adopting traditional machine learning approaches to predict housing prices accurately has been consider, but they are rarely concerned about the performance of individual models and neglect the less popular but complex models. A survey of literature is carried out to analyze the relevant attributes, factors and the most efficient models to predict the house prices. Machine learning has played major role in image detection, spam reorganization, normal speech command, product recommendation and medical diagnosis.

description: We observed the K7 class III star NO Lup in an ALMA survey of the 1-3 Myr Lupus association and detected circumstellar dust and CO gas. Here we show that the J = 3-2 CO emission is both spectrally and spatially resolved, with a broad velocity width ${\sim}19$kms$^{-1}$ for its resolved size ${\sim}1''$ (${\sim}130$ au). We model the gas emission as a Keplerian disc, finding consistency, but only with a central mass of ${\sim}11M_{\odot}$, which is implausible given its spectral type and X-Shooter spectrum. A good fit to the data can also be found by modelling the CO emission as outflowing gas with a radial velocity ${\sim}22$kms$^{-1}$. We interpret NO Lup's CO emission as the first imaged class III circumstellar disc with outflowing gas. We conclude that the CO is continually replenished, but cannot say if this is from the break-up of icy planetesimals or from the last remnants of the protoplanetary disc. We suggest further work to explore the origin of this CO, and its higher than expected velocity in comparison to photoevaporative models.

description: We show that the Sokolov--Ternov effect -- the depolarization of particles in storage rings coming from synchrotron radiation due to spin flip transitions -- is physically equivalent to the Unruh effect for circular acceleration if one uses a spin 1/2 particle as the Unruh--DeWitt detector. It is shown that for the electron, with gyromagnetic number $g \approx 2$, the exponential contribution to the polarization, which usually characterizes the Unruh effect, is "hidden" in the standard Sokolov-Ternov effect making it hard to observe. Thus, our conclusions are different in detail from previous work.
