Shallow crustal structure beneath the Juan de Fuca ridge from 2 seismic refraction tomography
Creators: name: White, Donald John
Publisher: name: University of British Columbia
Year: 2010

description: In May, 1982 a seismic refraction survey, using a 32 I airgun and a radio telemetering sonobuoy system with direct digital recording, was carried out in Georgia Strait. The objectives of this experiment were determination of the upper crustal structure beneath the Strait and investigation of the proposed existence of a major fault separating Vancouver Island from the continental mainland. Three reversed profiles across the Strait and reversed lines along it on either side were shot. In addition, the southernmost line from northern Galiano Island to Point Grey was recorded digitally from a telemetered land-based station on Galiano Island. The refraction data are supplemented by several high resolution reflection profiles from previous experiments. Two-dimensional models of the crustal structure across the Strait have been constructed using a forward modelling ray trace and synthetic seismogram algorithm to match the travel times and amplitude characteristics of the data. Generally, these models consist of 3 layers. The first consists of unconsolidated sediments and Pleistocene glacial deposits varying in thickness up to 1 km. The velocity of this layer is assumed to be 1.6 km/s due to lack of velocity information. The second layer represents Upper Cretaceous sediments of the Nanaimo Group and possibly Chuckanut Formation, having velocities ranging from 3.6 km/s to 4.2 km/s. It varies in thickness up to 2 km, thinning toward the mainland side of the Strait. The third layer consists of a thin transitional zone, with velocity 6.0-6.1 km/s at the surface and gradient 0.5 km/s/km, beneath which the velocity gradient is decreased to 0.1-0.15 km/s/km. This layer dips at angles of 2°-16° toward Vancouver Island. This layer is likely the extension of the Coast. Range intrusives. The Malaspina fault proposed for the Strait of Georgia is not observed, although some uncertainty remains due to termination of seismic coverage short of the mainland. A local fault with calculated throw of 0.55 km has been located approximately 15 km northeast of Galiano Island. The dip and strike of the fault are poorly constrained. Maximum depth of penetration obtained in this study is about 3 km.

description: Particle models with finitely many types of particles are considered, both on $\mathbb{Z}^d$ and on discrete point sets of finite local complexity. Such sets include many standard examples of aperiodic order such as model sets or certain substitution systems. The particle gas is defined by an interaction potential and a corresponding Gibbs measure. Under some reasonable conditions on the underlying point set and the potential, we show that the corresponding diffraction measure almost surely exists and consists of a pure point part and an absolutely continuous part with continuous density. In particular, no singular continuous part is present.

description: We perform the analog to the "water bell" experiment using non-cohesive granular material. When a jet of granular material, many particles wide, rebounds from a fixed cylindrical target, it deforms into a sharply-defined sheet or cone with a shape that mimics a liquid with zero surface tension. The particulate nature of granular material becomes apparent when the number of particles in the cross-section of the jet is decreased and the emerging sheets and cones broaden and gradually disintegrate into a broad spray. This experiment has its counterpart in the behavior of the quark-gluon plasma generated by collisions of gold ions at the Relativistic Heavy Ion Collider. There a high density of inter-particle collisions gives rise to collective behavior that has also been described as a liquid.

Mixed SIGNals: Sign Language Production via a Mixture of Motion Primitives

description: It is common practice to represent spoken languages at their phonetic level. However, for sign languages, this implies breaking motion into its constituent motion primitives. Avatar based Sign Language Production (SLP) has traditionally done just this, building up animation from sequences of hand motions, shapes and facial expressions. However, more recent deep learning based solutions to SLP have tackled the problem using a single network that estimates the full skeletal structure. We propose splitting the SLP task into two distinct jointly-trained sub-tasks. The first translation sub-task translates from spoken language to a latent sign language representation, with gloss supervision. Subsequently, the animation sub-task aims to produce expressive sign language sequences that closely resemble the learnt spatio-temporal representation. Using a progressive transformer for the translation sub-task, we propose a novel Mixture of Motion Primitives (MoMP) architecture for sign language animation. A set of distinct motion primitives are learnt during training, that can be temporally combined at inference to animate continuous sign language sequences. We evaluate on the challenging RWTH-PHOENIX-Weather-2014T(PHOENIX14T) dataset, presenting extensive ablation studies and showing that MoMP outperforms baselines in user evaluations. We achieve state-of-the-art back translation performance with an 11% improvement over competing results. Importantly, and for the first time, we showcase stronger performance for a full translation pipeline going from spoken language to sign, than from gloss to sign.

description: In random cellular systems, both observation and maximum entropy inference give a specific form to the topological pair correlation: it is bi-affine in the cells number of edges with coefficients depending on the distance between the two cells of the pair. Assuming this form for the pair correlations, we make explicit the conditions of statistical independence at large distance. When, on average, the defects do not contribute, the layer population and the enclosed topological charge both increase polynomially with distance. In dimension 2, the exponent of the leading terms depend on sum rules satisfied, or not, by the maximum entropy coefficients.

description: In environments such as core-collapse supernovae, neutron star mergers, or the early universe, where the neutrino fluxes can be extremely high, neutrino-neutrino interactions are appreciable and contribute substantially to their flavor evolution. Such a system of interacting neutrinos can be regarded as a quantum many-body system, and prospects for nontrivial quantum correlations, i.e., entanglement, developing in a gas of interacting neutrinos have been investigated previously. In this work, we uncover an intriguing connection between the entropy of entanglement of individual neutrinos with the rest of the ensemble, and the occurrence of spectral splits in the energy spectra of these neutrinos, which develop as a result of collective neutrino oscillations. In particular, for various types of neutrino spectra, we demonstrate that the entanglement entropy is highest for the neutrinos whose locations in the energy spectrum are closest to the spectral split(s). This trend demonstrates that the quantum entanglement is strongest among the neutrinos that are close to these splits, a behavior that seems to persist even as the size of the many-body system is increased.

description: We present a quantum analysis of the massless excitations in graphene with a charge impurity. When the effective charge exceeds a certain critical value, the spectrum is quantized and is unbounded from below. The corresponding eigenstates are square-integrable at infinity and have a rapidly oscillatory behaviour in the short distance, which can be interpreted as a fall to the centre. Using a cutoff regularization, we show that the effective Coulomb interaction strength is driven to its critical value under the renormalization group flow. In the subcritical region, we find bound states with imaginary values of the energy for certain range of the system parameters. The physical significance of these bound states with imaginary eigenvalues is discussed.

description: We perform a Noether analysis for a description of translation transformations in 4D $κ$-Minkowski noncommutative spacetime which is based on the structure of a 5D differential calculus. The techniques that some of us had previously developed (hep-th/0607221) for a description of translation transformations based on a 4D differential calculus turn out to be applicable without any modification, and they allow us to show that the basis usually adopted for the 5D calculus does not take into account certain aspects of the structure of time translations in $κ$-Minkowski. We propose a change of basis for the 5D calculus which leads to a more intuitive description of time translations.

description: Abundance analyses from high-resolution optical spectra are presented for 19 Type II Cepheids in the Galactic field. The sample includes both short-period (BL Her) and long-period (W Vir) stars. This is the first extensive abundance analysis of these variables. The C, N, and O abundances with similar spreads for the BL Her and W Vir show evidence for an atmosphere contaminated with $3α$-process and CN-cycling products. A notable anomaly of the BL Her stars is an overabundance of Na by a factor of about five relative to their presumed initial abundances. This overabundance is not seen in the W Vir stars. The abundance anomalies running from mild to extreme in W Vir stars but not seen in the BL Her stars are attributed to dust-gas separation that provides an atmosphere deficient in elements of high condensation temperature, notably Al, Ca, Sc, Ti, and $s$-process elements. Such anomalies have previously been seen among RV Tau stars which represent a long-period extension of the variability enjoyed by the Type II Cepheids. Comments are offered on how the contrasting abundance anomalies of BL Her and W Vir stars may be explained in terms of the stars' evolution from the blue horizontal branch.

description: Context. The origin of the heating of the solar atmosphere is still an unsolved problem. As the photosphere and chromosphere radiate more energy than the solar corona, it is challenging but important to reveal all the mechanisms that contribute to plasma heating there. Ion-neutral collisions could play an important role. Aims. We aim to investigate the impulsively generated two-fluid magnetoacoustic waves in the partially ionized solar chromosphere and to study the associated heating and plasma outflows, which higher up may result in nascent solar wind. Methods. To describe the plasma dynamics, we applied a two-fluid model in which ions+electrons and neutrals are treated as separate fluids. We solved the two-fluid equations numerically using the JOANNA code. Results. We show that magnetoacoustic waves triggered in the photosphere by localised velocity pulses can steepen into shocks which heat the chromosphere through ion-neutral collisions. Pulses of greater amplitude heat plasma more effectively and generate larger plasma outflows. Rising the altitude at which the pulse is launched results in opposite effects, mainly in local cooling of the chromosphere and slower plasma outflows. Conclusions. Even a solitary pulse results in a train of waves. These waves can transform into shock waves and release thermal energy, heating the chromosphere significantly. A pulse can drive vertical flows which higher up can result in the origin of the solar wind.

description: Although electrons and photons are intrinsically different, importing useful concepts in optics to electronics performing similar functions has been actively pursued over the last two decades. In particular, collimation of an electron beam is a long-standing goal. We show that ballistic propagation of an electron beam with virtual no spatial spreading or diffraction, without a waveguide or external magnetic field, can be achieved in graphene under an appropriate class of experimentally feasible one-dimensional external periodic potentials. The novel chiral quasi-one-dimensional metallic state that the charge carriers are in originates from a collapse of the intrinsic helical nature of the charge carriers in graphene owing to the superlattice potential. Beyond providing a new way to constructing chiral one-dimensional states in two dimensions, our findings should be useful in graphene-based electronic devices (e.g., for information processing) utilizing some of the highly developed concepts in optics.

description: An investigation of the two-dimensional Widom-Rowlinson lattice gas under an applied drive uncovered a remarkable non-equilibrium steady state in which uniform stripes (reminiscent of an equilibrium lamellar phase) form perpendicular to the drive direction [R. Dickman and R. K. P. Zia, Phys. Rev. E 97, 062126 (2018)]. Here we study this model at low particle densities in two and three dimensions, where we find a disordered phase with a characteristic length scale (a "microemulsion") along the drive direction. We develop a continuum theory of this disordered phase to derive a coarse-grained field-theoretic action for the non-equilibrium dynamics. The action has the form of two coupled driven diffusive systems with different characteristic velocities, generated by an interplay between the particle repulsion and the drive. We then show how fluctuation corrections in the field theory may generate the characteristic features of the microemulsion phase, including a peak in the static structure factor corresponding to the characteristic length scale. This work lays the foundation for understanding the stripe phenomenon more generally.

Horndon-on-the-Hill, Essex: a morphological analysis of the Late Saxon and medieval settlement
Creators: name: Secker, Daniel
Publisher: name: Archaeology Data Service
Year: 2023

description: Medieval Settlement Research, 38, 1-19
description: Horndon-on-the-Hill in south Essex is a former small market town which was also the site of a short-lived mint, as evidenced by a find of a single coin of Edward the Confessor, while earthworks to the east of the High Road are suggestive of a defensive enclosure. This paper puts the limited archaeological evidence from the settlement centre into its topographical and historical context. Using regressive analysis from cartographic sources, it is suggested that Horndon-on-the-Hill was founded as a defended settlement during the reign of Æthelred II, when the Anglo-Saxon Chronicle records a Viking attack on London and raids on the Thames Estuary and Essex coast.

The immediate manifestation of metastable states' multiplicity as staircases of magnetizations (polarizations) curves in the temperature cycling experiments is explained and described. The obtained results are in a reasonable qualitative agreement with the existing experimental data.

Christian Colonisation of the Urban Space of Sagunt, Valencian Country (1238-1350)
Creators: name: Mateu, Alexandre

Year: 2023

description: Medieval Settlement Research, 38, 20-30
description: This study addresses the process of appropriation of urban space by Christians in the Kingdom of Valencia, after the conquest by King James I in 1238. Using Sagunt as a case study, our aim is to examine what the medina, i.e. the older part of the town, was like during the era of Muslim rule (the 'Andalusi' period); and how it changed after the expulsion of its Muslim inhabitants in 1248. By utilising extant urban morphology and historical maps, alongside documents and archaeological reports, we can demonstrate the complete transformation of residential areas following Christian colonisation. During this process, the Andalusi street network was modified but never entirely transformed, retaining much of its historical character. The nature of these urban changes leads us to propose the crucial importance of the Christian settlers and the small- to medium-scale building operations they carried out as the principal subject of study when conducting this type of analysis.
Deposition of the cretaceous lower mannville group, Drumheller area, Alberta
Creators: name: Sonneveld, Ellen M.
Publisher: name: University of British Columbia
Year: 2010

description: The Lower Mannville Group of south-central Alberta represent part of an extensive Early Cretaceous drainage system incised into Paleozoic carbonates and shales. Sediments were deposited as debris flows, in bars of low sinuosity, sandy braided rivers, and in shallow fresh to brackish water lakes. Late Aptian-Early Albian transgression of the Moosebar-Clearwater Sea lead to formation of a large estuary in the Drumheller area. Petrographic examination of the basal alluvial sands indicates the existence of 3 lithologically distinct sandstones: (1) a basal immature chert arenite; (2) an immature quartz arenite; and (3) a mature to supermature quartz arenite, correlatable with the Ellerslie Formation. The change from cherty sandstone to quartzose sandstone reflects uplift to the east, of the Sweetgrass Arch and Swift Current Platform. Diagenetic modification of the sandstones include compaction and cementation by siderite, quartz, calcite, dolomite, barite, pyrite, and clay, all of which have reduced initial primary porosity. Secondary porosity was subsequently created through dissolution of early siderite cement. Oil emplacement in the Basal Quartz sands appears to follow cementation by siderite and silica.

We discuss how join inverse rig categories do not in general capture pattern-matching, the core construct Theseus uses to enforce reversibility. We then derive a categorical structure to add to join inverse rig categories in order to capture pattern-matching. We show how such a structure makes an adequate model for reversible pattern-matching.

The nanowires have a "striped" structure (gold-PEDOT/PSS-gold), typically 8um long (1um-6um-1um for each section, respectively) and 220 nm in diameter. Single-nanowire devices were contacted by pre-fabricated gold electrodes using dielectrophoretic assembly. A polymer conductivity of 11.5 +/- 0.7 S/cm and a contact resistance of 27.6 +/- 4 kOhm were inferred from measurements of nanowires of varying length and diameter. The nanowire sensors detect a variety of odors, with rapid response and recovery (seconds). The response (R-R0)/R0 varies as a power law with analyte concentration.

description: With a sample of about 384 million BBbar pairs recorded with the BABAR detector, we search for the flavor-changing charged current transition B+ -> τνand perform an amplitude analysis of the effective flavor-changing neutral current transition B+ -> ϕ(1020)K*(892)+. We also extend our search for other K* final states in the decay B0 -> phi(1020)K*0 with a large K*0 -> K+pi- invariant mass. Two samples of events with one reconstructed hadronic B decay or one reconstructed semileptonic B decay are selected, and in the recoil a search for B+ -> τνis performed. We find a 2.6 sigma (3.2 sigma not including expected background uncertainty) excess in data which can be converted to a preliminary branching fraction central value of BR(B+ -> τν) = (1.20 +0.40-0.38 +0.29-0.30 +-0.22) 10^-4. With the decay B+- -> ϕ(1020)K*(892)+-, twelve parameters are measured, where our measurements of f_L=0.49+-0.05+-0.03, f_perp=0.21+-0.05+-0.02, and the strong phases point to the presence of a substantial helicity-plus amplitude from a presently unknown source.

description: We present an explanation for the anomalous behavior in tunneling conductance and noise through a point contact between edge states in the Jain series $ν=p/(2np+1)$, for extremely weak-backscattering and low temperatures [Y.C. Chung, M. Heiblum, and V. Umansky, Phys. Rev. Lett. {\bf{91}}, 216804 (2003)]. We consider edge states with neutral modes propagating at finite velocity, and we show that the activation of their dynamics causes the unexpected change in the temperature power-law of the conductance. Even more importantly, we demonstrate that multiple-quasiparticles tunneling at low energies becomes the most relevant process. This result will be used to explain the experimental data on current noise where tunneling particles have a charge that can reach $p$ times the single quasiparticle charge. In this paper we analyze the conductance and the shot noise to substantiate quantitatively the proposed scenario.

Gravatamberus

description: Gravatamberus
- The genus was established by Mendes & Andersen (2008); they included five species found in Brazil, Chile, Costa Rica, Guatemala, Mexico and Venezuela. Gravatamberus curtus Mendes & Andersen was described from material (three specimens) from Mexico and northwestern Costa Rica; G. guatemaltecus was described from a single specimen from Guatemala. The two species were diagnosed by the number of setae in cell m proximal to RM, number of setae on the subcosta, the length of the costal extension and the AR: G. curtus has <10 setae in cell m proximal to RM (G. guatemaltecus>10); subcosta with 6–15 setae (G. guatemaltecus 16), costal extension 68-86 µm (G. guatemaltecus 161); AR 0.64–0.69 (G. guatemaltecus 0.26).
Eighteen males of Gravatamberus were collected; unfortunately, antennae were missing on all of them. All had a costal extension, ranging from 128 to 200 µm (Table 1), greater than that recorded for G. curtus. However, the range of setae in cell m proximal to RM ranged from 0 to 24 in the Zurqui material, regardless of costal extension length, suggesting that this character does not aid in distinguishing G. curtus from G. guatemaltecus. All Gravatamberus collected in this study are considered to represent G. guatemaltecus.
Data also indicate that the midges had more setae in cell m and on the subcosta from February to May, with fewer setae present in those wing areas from May (one specimen) through October.

Modelling the stellar halo with RR-Lyrae stars

description: A seven-parameter distribution function (DF) is fitted to $20\,000$ RR-Lyrae stars for which only astrometric data are available. The observational data are predicted by the DF in conjunction with the gravitational potential of a self-consistent model Galaxy defined by DFs for the dark halo, the bulge and a four-component disc. Tests of the technique developed to deal with missing line-of-sight velocities show that adding such velocities tightens constraints on the DF only slightly. The recovered model of the RR-Lyrae population confirms that the population is flattened and has a strongly radially biased velocity distribution. At large radii its density profile tends to $ρ\sim r^{-4.5}$ but no power law provides a good fit inside the solar sphere. The model is shown to provide an excellent fit to the data for stars brighter than $r=16.5$ but at certain longitudes it predicts too few faint stars at Galactocentric radii $\sim20\mbox{kpc}$, possibly signalling that the halo is not axisymmetric. The DF is used to predict the velocity distribution of BHB stars for which space velocities are available. The $z$ components are predicted successfully but too much anisotropy in the $v_Rv_ϕ$ plane is expected.

Toward Psycho-robots

description: We try to perform geometrization of psychology by representing mental states, <>, by points of a metric space, <>. Evolution of ideas is described by dynamical systems in metric mental space. We apply the mental space approach for modeling of flows of unconscious and conscious information in the human brain. In a series of models, Models 1-4, we consider cognitive systems with increasing complexity of psychological behavior determined by structure of flows of ideas. Since our models are in fact models of the AI-type, one immediately recognizes that they can be used for creation of AI-systems, which we call psycho-robots, exhibiting important elements of human psyche. Creation of such psycho-robots may be useful improvement of domestic robots. At the moment domestic robots are merely simple working devices (e.g. vacuum cleaners or lawn mowers) . However, in future one can expect demand in systems which be able not only perform simple work tasks, but would have elements of human self-developing psyche. Such AI-psyche could play an important role both in relations between psycho-robots and their owners as well as between psycho-robots. Since the presence of a huge numbers of psycho-complexes is an essential characteristic of human psychology, it would be interesting to model them in the AI-framework.
Multifactor Analysis of Multiscaling in Volatility Return Intervals

description: We study the volatility time series of 1137 most traded stocks in the US stock markets for the two-year period 2001-02 and analyze their return intervals $τ$, which are time intervals between volatilities above a given threshold $q$. We explore the probability density function of $τ$, $P_q(τ)$, assuming a stretched exponential function, $P_q(τ) \sim e^{-τ^γ}$. We find that the exponent $γ$ depends on the threshold in the range between $q=1$ and 6 standard deviations of the volatility. This finding supports the multiscaling nature of the return interval distribution. To better understand the multiscaling origin, we study how $γ$ depends on four essential factors, capitalization, risk, number of trades and return. We show that $γ$ depends on the capitalization, risk and return but almost does not depend on the number of trades. This suggests that $γ$ relates to the portfolio selection but not on the market activity. To further characterize the multiscaling of individual stocks, we fit the moments of $τ$, $μ_m \equiv )^m>^{1/m}$, in the range of $10 < \le 100$ by a power-law, $μ_m \sim ^δ$. The exponent $δ$ is found also to depend on the capitalization, risk and return but not on the number of trades, and its tendency is opposite to that of $γ$. Moreover, we show that $δ$ decreases with $γ$ approximately by a linear relation. The return intervals demonstrate the temporal structure of volatilities and our findings suggest that their multiscaling features may be helpful for portfolio optimization.

description: We report Relativity tests based on data from two simultaneous Michelson-Morley experiments, spanning a period of more than one year. Both were actively rotated on turntables. One (in Berlin, Germany) uses optical Fabry-Perot resonators made of fused silica; the other (in Perth, Australia) uses microwave whispering-gallery sapphire resonators. Within the standard model extension, we obtain simultaneous limits on Lorentz violation for electrons (5 coefficients) and photons (8) at levels down to $10^{-16}$, improved by factors between 3 and 50 compared to previous work.

description: We study electronic properties of graphene derivatives which have closed edges. They are finite-length graphene nanoribbons and graphene nanodisks. No metallic states are found in finite-length zigzag nanoribbons though all infinite-length zigzag nanoribbons are metallic. We also study hexagonal, parallelogrammic and trigonal nanodisks with zigzag or armchair edges. No metallic states are found in these nanodisks either except trigonal zigzag nanodisks. It is interesting that we can design the degeneracy of the metallic states arbitrarily in trigonal zigzag nanodisks by changing the size.

description: We present sensitive, high angular resolution ($0\rlap.{''}05$) VLA continuum observations made at 7 mm of the core of the HH 111/121 quadrupolar outflow. We estimate that at this wavelength the continuum emission is dominated by dust, although a significant free-free contribution ($\sim$30%) is still present. The observed structure is formed by two overlapping, elongated sources approximately perpendicular to each other as viewed from Earth. We interpret this structure as either tracing two circumstellar disks that exist around each of the protostars of the close binary source at the core of this quadrupolar outflow or a disk and a jet perpendicular to it. Both interpretations have advantages and disadvantages, and future high angular resolution spectroscopic millimeter observations are required to favor one of them in a more conclusive way.

description: Using data warehouses to analyse multidimensional data is a significant task in company decision-making.The data warehouse merging process is composed of two steps: matching multidimensional components and then merging them. Current approaches do not take all the particularities of multidimensional data warehouses into account, e.g., only merging schemata, but not instances; or not exploiting hierarchies nor fact tables. Thus, in this paper, we propose an automatic merging approach for star schema-modeled data warehouses that works at both the schema and instance levels. We also provide algorithms for merging hierarchies, dimensions and facts. Eventually, we implement our merging algorithms and validate them with the use of both synthetic and benchmark datasets.
