description: A renormalization group transformation suitable for spin glass models and, more generally, for disordered models, is presented. The procedure is non-standard in both the nature of the additional interactions and the coarse graining transformation, that is performed on the overlap probability measure (which is clearly non-Gibbsian). Universality classes are thus naturally defined on a large set of models, going from $\Z_2$ and Gaussian spin glasses to Ising and fully frustrated models, and others.

description: Vortragsfolien des Vortrags: Perkolationsanalyse – Archäologische Anwendungen auf unterschiedlichen räumlichen Ebenen Maddison, Simon , Schmidt, Sophie C. Dieser Beitrag hat zum Ziel, den räumlichen Cluster-Algorithmus der Perkolationsanalyse vorzustellen und anhand von zwei Fallstudien auf sehr unterschiedlichem Maßstab mögliche Nutzungsbereiche für die Archäologie aufzuzeigen. Dem auf Perkolationstheorie und euklidischer Distanz basierenden Cluster-Algorithmus liegt der von Arcaute et al (2016) adaptierte City Clustering Algorithm zugrunde, der in der freien Programmiersprache R umgesetzt wurde. Gegenüber anderen Clusteralgorithmen zeichnen ihn seine geringe mathematische Komplexität und seine Robustheit aus. Die archäologischen Fallstudien behandeln einerseits eine Clusteranalyse auf nationaler, andererseits die Berechnung von Befundabständen auf sub-regionaler Ebene. Im ersten Fall handelt es sich um die Analyse befestigter Höhensiedlung in Großbritannien und Irland sowie Domesday-Fundstellen in England, deren Perkolation mögliche sozio-politische Einheiten durch die Zeiten verfolgen lässt. Die zweite Fallstudie behandelt die landschaftsarchäologische Frage, wie weit zwei zeitgleiche Funde von einander entfernt sein sollten, um zwei unterschiedliche Fundstellen zu markieren. Dies wird anhand einer 13km langen kontinuierlichen Ausgrabung entlang einer Bundesstraße in Sachsen-Anhalt berechnet. Beide Fragestellungen lassen sich mit dem vorgestellten Algorithmus gewinnbringend beantworten.

 Type material. Holotype female: South Africa, West Cape, Tsitsikamma, Storms River [GIS: -33.964, 23.898], ex Kiggelaria africana, 14 Nov. 2006, B. Jordal, leg. Allotype male and paratypes: same data as holotype (4); South Africa, West Cape, Natures Valley, deVasselot [GIS: -33.965, 23.562], ex Rhus chirindaensi,s 9 Nov. 2006, B. Jordal, leg. (7). Holotype, allotype and two paratypes in SAMC, six paratypes in ZMUB, two in NHMW.
 Diagnosis. Female frons flattened, lower median third glabrous, shiny, with short setae encircling the glabrous area; antennal club with two distinct and angularly procurved sutures; elytral interstriae with regular rows of erect setae separated in a row by half the length of a seta, closer on declivity than on disk.
 Description, female. Length 1.4–1.5 mm, 2.6–2.7 × as long as wide; colour dark brown. flattened, on lower median third glabrous, with short setae in circle around glabrous area. Eyes separated above by 2.5–2.8 × the width. Antennal scapus triangular with setae as long as antennal club; the club with two angularly procurved sutures. Pronotum with distinct summit, asperities on anterior half; vestiture mixed hair-like, mainly on posterior half, and scale-like, mainly on anterior half. Elytral interstriae with regular rows of erect, pointed, bristle-like setae separated within rows on average by two-thirds their length, closer on declivity. Protibiae with three apical denticles.
 Etymology. Composed by the stem of the Latin adjective calvus, meaning hairless, and frons, referring to the glabrous lower median part of the frons in the female.
 Distribution and biology. South Africa. It was collected twice in coastal forest sites in the Cape region. Fully developed broods were dissected from phloem of 2–5 cm thick branches of Kiggelaria africana (Achariaceae) and Searsia chirindensis (Anacardiaceae). Among the seven families studied, one contained a male-female pair, five had a bigamous structure and one had three females per male. Brood size ranged between 30 to 60 larvae (n=14) per family.
 Remarks. This species is very similar to the next one, D. medius, both with densely placed, pointed, bristle-like setae, but distinguished in females by the glabrous lower median frons, and by genetic data.

description: Quasi-periodic pulsations (QPPs) are a common feature of solar flares, but previously there has been a lack of observational evidence to support any of the theoretical models that might explain the origin of QPPs. We aimed to determine if there are any relationships between the QPP period and other properties of the flaring region, using the sample of flares with QPPs from Pugh et al. (2017b). If any relationships exist then these can be compared with scaling laws for the theoretical QPP mechanisms. To obtain the flaring region properties we made use of the AIA 1600 and HMI data. The AIA 1600 images allow the flare ribbons to be seen while the HMI magnetograms allow the positive and negative magnetic polarity ribbons to be distinguished and the magnetic properties determined. The ribbon properties calculated in this study were the ribbon separation distance, area, total unsigned magnetic flux, and average magnetic field strength. Only the flares that occurred within \pm 60° of the solar disk centre were included, which meant a sample of 20 flares with 22 QPP signals. Positive correlations were found between the QPP period and the ribbon properties. The strongest correlations were with the separation distance and magnetic flux. Because these ribbon properties also correlate with the flare duration, and the relationship between the QPP period and flare duration may be influenced by observational bias, we also made use of simulated data to check if artificial correlations could be introduced. These simulations show that although QPPs cannot be detected for certain combinations of QPP period and flare duration, this does not introduce an apparent correlation. There is evidence of relationships between the QPP period and flare ribbon properties, and in the future the derived scaling laws between these properties can be compared to equivalent scaling laws for theoretical QPP mechanisms.

description: Clustering algorithms have regained momentum with recent popularity of data mining and knowledge discovery approaches. To obtain good clustering in reasonable amount of time, various meta-heuristic approaches and their hybridization, sometimes with K-Means technique, have been employed. A Kalman Filtering based heuristic approach called Heuristic Kalman Algorithm (HKA) has been proposed a few years ago, which may be used for optimizing an objective function in data/feature space. In this paper at first HKA is employed in partitional data clustering. Then an improved approach named HKA-K is proposed, which combines the benefits of global exploration of HKA and the fast convergence of K-Means method. Implemented and tested on several datasets from UCI machine learning repository, the results obtained by HKA-K were compared with other hybrid meta-heuristic clustering approaches. It is shown that HKA-K is atleast as good as and often better than the other compared algorithms.

 Type material. Holotype female: South Africa, East Cape, Hogsback [GIS: -32.595, 26.960], ex Rhus pyroides, 16 Nov. 2006, B. Jordal, leg. Allotype male and paratypes: same data as holotype (5). Holotype and allotype in SAMC, two paratypes in ZMUB, one in NHMW.
 Diagnosis. Female frons lightly concave, with short setae in impressed area not longer than pedicel; antennal club with two procurved, slightly bisinuate, sutures; elytral interstriae with regular rows of erect setae separated in a row by half the length of a seta, closer on declivity than on disk.
 Description, female. Length 1.4–1.6 mm, 2.6–2.7 × as long as wide; colour dark brown. Frons lightly impressed on lower half; entire surface covered by short setae. Eyes separated above by 2.5–2.8 × the width. Antennal scapus triangular with setae as long as antennal club; the club with two procurved sutures somewhat bisinuate. Pronotum with distinct summit, asperities on anterior half; vestiture mixed hair-like, mainly on posterior half, and scale-like, mainly on anterior half. Elytral interstriae with regular rows of erect and pointed bristle-like setae separated within rows by half their length, closer on declivity. Protibiae with three apical denticles.
 Etymology. The Latin nominative adjective medius has several meanings, among them middle or half, referring to the moderately setose female frons, intermediate between calvifrons and pilifrons.
 Distribution and biology. South Africa. Only known from the type locality in Hogsback where it was dissected from a thin branch of Searsia pyroides (Anacardiaceae). Broods were mature and mixed, not allowing study of the mating system.
 Remarks. Distinguished from the closest relative D. calvifrons by the setose central median frons and the bisinuate sutures on the antennal club. This species also has slightly longer strial setae which occasionally overlap and tend to be slightly raised.

description: In this letter we complement previous studies on exclusive vector meson photoproduction in hadronic collisions presenting a comprehensive analysis of the $t$ - spectrum measured in exclusive $ρ$ and $J/Ψ$ photoproduction in $pA$ collisions at the LHC. We compute the differential cross sections considering two phenomenological models for the gluon saturation effects and present predictions for $pPb$ and $pCa$ collisions. Moreover, we compare our predictions with the recent preliminary CMS data for the exclusive $ρ$ photoproduction. We demonstrate that the gluon saturation models are able to describe the CMS data at small - $t$. On the other hand, the models underestimate the few data point at large -- $t$. Our results indicate that future measurements of the large -- $t$ region can be useful to probe the presence or absence of a dip in the $t$ -- spectrum and discriminate between the different approaches to the gluon saturation effects.

description: We revisit the correlation between the mid-infrared (6 $μ$m) and hard X-ray (2--10 keV) luminosities of active galactic nuclei (AGNs) to understand the physics behind it. We construct an X-ray flux-limited sample of 571 type 1 AGNs with $f_{0.5-2.0 \,{\rm keV}} > 2.4 \times 10^{-12}$ erg cm$^{-2}$ s$^{-1}$, drawn from the ROSAT Bright Survey catalog. Cross-matching the sample with infrared data taken from Wide-field Infrared Survey Explorer, we investigate the relation between the rest-frame 6 $μ$m luminosity ($L_{\rm 6}$) and the rest-frame 2--10 keV luminosity ($L_{\rm X}$), where $L_{\rm 6}$ is corrected for the contamination of host galaxies by using the spectral energy distribution fitting technique. We confirm that $L_{\rm 6}$ and $L_{\rm X}$ are correlated over four orders of magnitude, in the range of $L_{\rm X} = 10^{42-46}$ erg s$^{-1}$. We investigate what kinds of physical parameters regulate this correlation. We find that $L_{\rm X}$/$L_{\rm 6}$ clearly depends on the Eddington ratio ($λ_{\rm Edd}$) as $\log λ_{\rm Edd} = -(0.56 \pm 0.10) \log \, (L_{\rm X}/L_{\rm 6}) - (1.07 \pm 0.05)$, even taking into account quasars that are undetected by ROSAT as well as those detected by XMM-Newton in the literature. We also add hyper-luminous quasars with $L_{\rm 6}$ $>$ 10$^{46}$ erg s$^{-1}$ in the literature and perform a correlation analysis. The resultant correlation coefficient is $-0.41 \pm 0.07$, indicating a moderately tight correlation between $L_{\rm X}$/$L_{\rm 6}$ and $λ_{\rm Edd}$. This means that AGNs with high Eddington ratios tend to have lower X-ray luminosities with respect to the mid-infrared luminosities. This dependence can be interpreted as a change in the structure of the accretion flow.

description: A Realidade Aumentada usa a renderização de modelos de objectos para complementar informação numa cena física. Para conseguir este objectivo (atingir esta meta), esses modelos necessitam de ser referenciados aos objectos físicos que é suposto serem aumentados. Esta referenciação requer uma calibração dos dispositivos usados para a projecção das imagens aumentadas, assim como dos dispositivos usados para adquirir a informação 3D da cena física. No caso de o aumento de realidade incluir nova geometria, as imagens aumentadas deverão ser projectadas e visualizadas em estéreo, de modo que a cena composta resultante faça sentido. Usualmente, bons exemplos de realidade aumentada são muito caros e as soluções implementadas são rígidas. Neste artigo descrevemos uma arquitectura e a sua implementação como um sistema flexível e de baixo custo, para criação e projecção de realidade aumentada. Na secção final apontamos alguns desenvolvimentos futuros para este sistema, requerendo mais experimentação.

description: We study how the ground state of the two-dimensional Ising spin glass with Gaussian interactions in zero magnetic field changes on altering the boundary conditions. The probability that relative spin orientations change in a region far from the boundary goes to zero with the (linear) size of the system L like L^{-lambda}, where lambda = -0.70 +/- 0.08. We argue that lambda is equal to d-d_f where d (=2) is the dimension of the system and d_f is the fractal dimension of a domain wall induced by changes in the boundary conditions. Our value for d_f is consistent with earlier estimates. These results show that, at zero temperature, there is only a single pure state (plus the state with all spins flipped) in agreement with the predictions of the droplet model.

description: Dark-matter-only simulations predict that dark matter halos have cusp-like inner density profiles, while observations of low-mass galaxies have found a range of inner slopes that are typically much shallower. It is still not well established whether this discrepancy can be explained by baryonic feedback or if it may require modified dark matter models. To better understand the diversity of dark matter profiles in dwarf galaxies, we undertook a survey of 26 low-mass galaxies ($\log M_*/\textrm{M}_\odot = 8.4-9.8$, $v_{\rm max} = 50-140$ km s$^{-1}$) within 30 Mpc using the Palomar Cosmic Web Imager, which is among the largest integral field spectroscopic surveys of its type. In this paper, we derive H$α$ velocity fields for the full sample with a typical spatial resolution of $\sim$160 pc. We extract rotation curves and verify their robustness to several choices in the analysis. We present a method for improving the velocity precision obtained from image slicing spectrographs using narrowband H$α$ images. For 11 galaxies, we compare the H$α$ velocity fields to CO kinematics measured using CARMA, finding the maps to be in good agreement. The standard deviation of the difference is typically $\sim$7 km s$^{-1}$, comparable to the level of turbulence in the interstellar medium, showing that the two tracers have substantially the same bulk kinematics. In a companion paper, we will use the rotation curves produced here to construct mass models of the galaxies and determine their dark matter density profiles.

description: A criação de modelos tridimensionais de ambientes urbanos utilizando modelação expedita é apresentada como sendo uma solução que permite ganhos financeiros e temporais, mantendo um nível de fidelidade visual aceitável. No entanto, a modelação de edifícios âncora (ou monumentais), identificativos de determinadas zonas urbanas, necessita de uma modelação mais cuidada devido ao elevado nível de detalhe necessário, recorrendose, geralmente, à sua modelação manual. Este artigo apresenta uma proposta de automatização do processo de modelação de edifícios através da introdução de conhecimento adicional num sistema de modelação expedita, a partir de descrições textuais. Embora os resultados obtidos não apresentem um nível de fidelidade visual muito elevada, exibem elevados níveis de correspondência entre o texto introduzido e o modelo tridimensional criado. Os resultados obtidos demonstram que a estrutura interna do protótipo é suficientemente flexível para construir distintos modelos de igreja e outros edifícios monumentais, com um nível de realismo muito aceitável. Os resultados demonstram ainda que é possível criar um modelo 3D a partir de um texto escrito em português perimitindo, deste modo, que utilizadores não especializados possam utilizar o sistema, reduzindo os custos globais de realização do projecto.

description: We present molecular dynamics simulations of driven vortices in layered superconductors in the presence of an external homogeneous force and point disorder. We use a model introduced by J.R.Clem for describing 3D vortex lines as stacks of 2D pancake vortices where only magnetic interactions are considered and the Josephson interlayer coupling is neglected. We numerically evaluate the long-range magnetic interaction between pancake vortices exactly. We analyze the vortex correlation along the field direction on (c-axis). We find that above the critical current, in the ``plastic flow'' regime, pancakes are completely uncorrelated in the c-direction. When increasing the current, there is an onset of correlation along the c-axis at the transition from plastic flow to a moving smectic phase. This transition coincides with the peak in the differential resistance.

description: Deep neural networks achieve stellar generalisation on a variety of problems, despite often being large enough to easily fit all their training data. Here we study the generalisation dynamics of two-layer neural networks in a teacher-student setup, where one network, the student, is trained using stochastic gradient descent (SGD) on data generated by another network, called the teacher. We show how for this problem, the dynamics of SGD are captured by a set of differential equations. In particular, we demonstrate analytically that the generalisation error of the student increases linearly with the network size, with other relevant parameters held constant. Our results indicate that achieving good generalisation in neural networks depends on the interplay of at least the algorithm, its learning rate, the model architecture, and the data set.

description: In this paper, we describe the theoretical foundations and engineering approach of an infrared-optical tracking system specially design for large scale immersive virtual environments (VE) or augmented reality (AR) settings. The system described is capable of tracking independent retro-reflective markers arranged in a 3D structure (artefact) in real time (25Hz), recovering all possible 6 Degrees of Freedom (DOF). These artefacts can be adjusted to the user's stereo glasses to track his/her pose while immersed in the VE or AR, or can be used as a 3D input device. The hardware configuration consists in 4 shutter-synchronized cameras attached with band-pass infrared filters and the artefacts are illuminated by infrared array-emitters. The system was specially designed to fit a room with sizes of 5.7m x 2.7m x 3.4 m, which match the dimensions of the CAVE-Hollowspace of Lousal where the system will be deployed. Pilot lab results have shown a latency of 40ms in tracking the pose of two artefacts with 4 infrared markers, achieving a frame-rate of 24.80 fps and showing a mean accuracy of 0.93mm/0.52º and a mean precision of 0.08mm/0.04º, respectively, in overall translation/rotation DOFs, fulfilling the system requirements initially defined.

Asymmetries Between the Production of Ds- and Ds+ Mesons from 500 GeV/c pi- Nucleon Interactions as Functions of x_F and square of p_t
Creators: name: E791 Collaboration
Publisher: name: arXiv
Year: 1997
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: This paper presents measurements of the production of Ds- mesons relative to Ds+ mesons as functions of x_F and square of p_t for a sample of 2445 Ds decays to phi pi. The Ds mesons were produced in Fermilab experiment E791 with 500 GeV/c pi- mesons incident on one platinum and four carbon foil targets. The acceptance-corrected integrated asymmetry in the x_F range -0.1 to 0.5 for Ds+- mesons is 0.032 +- 0.022 +- 0.022, consistent with no net asymmetry. The results, as functions of x_F and square of p_t, are compared to predictions and to the large production asymmetry observed for D+- mesons in the same experiment. These comparisons support the hypothesis that production asymmetries come from the fragmentation process and not from the charm quark production itself.

description: We report on optical spectroscopy obtained at the 10.4m Gran Telescopio Canarias of 28 Fermi gamma-ray sources that completes the study of a sample of 60 targets of unidentified objects for which the detection of an X-ray and/or radio source inside the 3FGL error box is available. The observations are aimed to characterize the nature and measure the redshift of these sources. For all optical counterparts, the observations allow us to establish their AGN nature. In particular, we found 24 BL Lac objects, one QSO, one NLSy1 and two objects showing spectral features typical of Seyfert 2 galaxies. For most of them, we determine a spectroscopic redshift, while for five we can set lower limits based on the lack of stellar features from the host galaxy. The global properties of the full sample are briefly discussed.

description: Mn $K$-edge fluorescence data are presented for thin film samples (3000~Å) of Colossal Magnetoresistive (CMR) La$_{0.67}$Ca$_{0.33}$MnO$_3$: as-deposited, and post-annealed at 1000 K and 1200 K. The local distortion is analyzed in terms of three contributions: static, phonon, and an extra, temperature-dependent, polaron term. The polaron distortion is very small for the as-deposited sample and increases with the annealing temperature. In contrast, the static distortion in the samples decreases with the annealing temperature. Although the local structure of the as-deposited sample shows very little temperature dependence, the change in resistivity with temperature is the largest of these three thin film samples. The as-deposited sample also has the highest magnetoresistance (MR), which indicates some other mechanism may also contribute to the transport properties of CMR samples. We also discuss the relationship between local distortion and the magnetization of the sample.

 Type material. Holotype, female: Madagascar, Montagne des Francais, 7.2 km SE Antsiranana, BLF3130, Malaise trap, B. Fischer, leg, 2001. The holotype is deposited in CAS.
 Diagnosis. Female frons with broad golden tuft of setae arising between inner eye margin to vertex, tips reaching level of antennal insertion; anterior margin of pronotum with a low irregular row of raised teeth; elytral apex very lightly inflated.
 Description, female. Length 1.8 mm, 2.8 × as long as wide; colour brown. Frons lightly concave, surface finely setose, largely covered by a broad tuft of golden setae with a median split, setae arising from inner margin of eyes to vertex, with tips reaching level of antennal insertion. Eyes separated above by 2.1 × their width. Antennal scapus triangular, with dense tuft of soft setae as long as scapus; club with two distinctly marked and strongly procurved sutures. Pronotum strongly asperate on anterior half, near anterior margin with a low irregular row of subcontiguous teeth or granules, smooth to lightly rugose behind summit; vestiture consisting of scattered small bristle- and hair-like setae. Elytral interstriae with densely placed spatulate setae in rows, striae not impressed, punctures obscure; elytral apex slightly inflated, posterolateral margin lightly granulated. Protibiae with three low apical tubercles (denticles not apparent).
 Etymology. A Latin nominative adjective meaning pretty, referring to the adorned female frons.
 Distribution and Biology. Madagascar. Only known from the type locality, collected in a Malaise trap.
 Remarks. This species has all of same essential characteristics as in D. acutior, but the elytral apex is less pointed, the raised crest near the anterior margin of the pronotum is lower and less regular, and the female frons has a shorter and much less voluminous tuft of setae.

description: Steepest-entropy-ascent quantum thermodynamics, or SEAQT, is a unified approach of quantum mechanics and thermodynamics that avoids many of the inconsistencies that can arise between the two theories. Given a set of energy levels, i.e., energy eigenstructure, accessible to a given physical system, SEAQT predicts the unique kinetic path from any initial non-equilibrium state to stable equilibrium by solving a master equation that directs the system along the path of steepest entropy ascent. There are no intrinsic limitations on the length and time scales the method can treat so it is well-suited for calculations where the dynamics over multiple spacial scales need to be taken into account within a single framework. In this paper, the theoretical framework and its advantages are described, and several applications are presented to illustrate the use of the SEAQT equation of motion and the construction of a simplified, reduced-order, energy eigenstructure.

A perturbative approach to the Bak-Sneppen Model

description: We study the Bak-Sneppen model in the probabilistic framework of the Run Time Statistics (RTS). This model has attracted a large interest for its simplicity being a prototype for the whole class of models showing Self-Organized Criticality. The dynamics is characterized by a self-organization of almost all the species fitnesses above a non-trivial threshold value, and by a lack of spatial and temporal characteristic scales. This results in {\em avalanches} of activity power law distributed. In this letter we use the RTS approach to compute the value of $x_c$, the value of the avalanche exponent $τ$ and the asymptotic distribution of minimal fitnesses.

Por recurso ao modelo 4D, definido em ambiente virtual, são visualizadas as características das componentes do edifício susceptíveis de desgaste/rotura durante o ciclo de vida do edifício. Numa fase inicial do desenvolvimento do projecto, foi estabelecida a interligação entre o modelo 3D, de um caso de estudo, e os elementos de iluminação inseridos no edifício. A informação relativa ao tempo de vida útil de lâmpadas, previsão de substituição e gestão de armazenamento é interactivamente visualizada por recurso ao modelo virtual concebido. A aplicação constitui uma ferramenta útil na amostragem de características dos elementos identificados no modelo 3D, na promoção de alertas de inspecção e na gestão de elementos em armazém necessários na monitorização e gestão de um edifício.
