description: Recent spectro-polarimetric observations of a sunspot showed the formation of bipolar magnetic patches in the mid penumbra and their propagation toward the outer penumbral boundary. The observations were interpreted as being caused by sea-serpent magnetic fields near the solar surface (Sainz Dalda & Bellot Rubio 2008). In this Letter, we develop a 3D radiative MHD numerical model to explain the sea-serpent structure and the wave-like behavior of the penumbral magnetic field lines. The simulations reproduce the observed behavior, suggesting that the sea-serpent phenomenon is a consequence of magnetoconvection in a strongly inclined magnetic field. It involves several physical processes: filamentary structurization, high-speed overturning convective motions in strong, almost horizontal magnetic fields with partially frozen field lines, and traveling convective waves. The results demonstrate a correlation of the bipolar magnetic patches with high-speed Evershed downflows in the penumbra. This is the first time that a 3D numerical model of the penumbra results in downward directed magnetic fields, an essential ingredient of sunspot penumbrae that has eluded explanation until now.

description:
Understanding the early lunar bombardment history hinges on reliable formation ages of the large lunar basins. Recent studies have shown that Zr minerals and Ca phosphates in petrographically, chemically, and microstructurally well-characterized lunar impactites can yield easily reproducible U-Pb ages that can be related to impacts. Geological, textural, and chemical arguments, plus impact melt distribution models, suggest that the widespread 3.92 Ga and 4.21 ages in breccias at the Apollo 14-17 landing sites likely reflect the Imbrium and Serenitatis impacts, respectively. However, the ages of other basins are more uncertain. Lunar granulites – impactites that were thermally metamorphosed by impact melt sheets – also should record basin-forming events. We have combined precise in situ Pb-Pb dates with Pb-Pb isochron dating to constrain the early history of the Apollo 17 granulite 77017. The rock contains annealed anorthositic gabbro clasts with relict igneous textures and a finer, thermally annealed matrix. High Ir abundances and the presence of metal indicate that the gabbro crystallized from impact melt. Baddeleyites define a homogeneous Pb-Pb age distribution (4175±3 Ma, n = 5), which is interpreted to date the crystallization of this impact melt. The phosphate Pb-Pb ages range between 4.18 and 4.13 Ga and are consistent with variable resetting by the metamorphic heating event. A Pb-Pb isochron yields a precise date for the granulite facies metamorphism (4143±1 Ma). The heating event may either relate to the impact that formed the Crisium basin or to another nearby basin-forming impact on the feldspathic highland terrane (Nectaris or Smythii).

description: This work presents information obtained from high-speed video and electrical monitoring of electrical breakdown (discharge) events during plasma electrolytic oxidation (PEO) of aluminium alloy substrates. Discharges were found to occur in extended sequences termed “cascades” at particular locations. This was a feature common to all the substrates and processing frequencies investigated. As the coating thickness increases, the characteristics remained broadly similar, although discharges become more energetic and longer-lived. Short PEO treatments were applied to existing PEO coatings in order to investigate the microstructural effects of discharge cascades. It was found that cascades persist at particular locations due to the residual deep pore channel left by previous discharges in the cascade. Observations were made of the way the coating was restructured around a cascade location. Samples were illuminated with very high intensity flashes during PEO processing, revealing that relatively large (1 mm diameter) bubbles form where a discharge emerges from the surface of a coating. Analysis of the overall energy consumption, as well as the energetic processes occurring within an individual discharge, indicate that the bubble growth occurs due to rapid volatilisation of water originating from the electrolyte. It is postulated that the growth of this bubble causes the electrical resistance to rise and is responsible for the termination of the discharge current. Investigations of high frequency (2,500 Hz) processing lead to the discovery of discharges occurring during the cathodic half-cycle, after a certain coating thickness had been achieved. Cathodic discharges were more energetic than anodic discharges, and created large craters in the coatings. Gas evolution was found to exceed the electrochemical Faraday yield, and was similar at low and high frequency initially. Once cathodic discharges began, the gas evolution rate increased and the coating mass gain levelled off.

description:
We present new results from a fission track (FT) dating approach on zircon and apatite from the Thuringian Forest, a prominent fault-bounded basement high in central Germany, and its southwestern periphery exposing Mesozoic strata. Samples were collected from exposures of igneous rocks as well as from lower to upper Permian (Rotliegend) continental red beds and volcanics recovered from a borehole southwest of the Thuringian Forest. Apatite FT ages range between 86 and 70 Ma, suggesting rock uplift associated with a well-documented and regionally important phase of NNE–SSW-directed intraplate contraction, resulting in spatially homogeneous removal of c. 3 km of Upper Palaeozoic to Mesozoic rocks. No change in apatite FT ages was detected across the regional-scale Franconian Fault system at the southwestern margin of the Thuringian Forest. Additionally, apatite FT ages of borehole samples southwest of the Thuringian Forest from depths between 9.6 and 2.7 km range from 57 to 18 Ma, suggesting post-Late Cretaceous cooling of this peripheral region. Our data hence support recent models of a continued large-scale domal uplift of Central Germany without verifiable or detectable involvement of individual faults.

description: In the current study, late Chinese–English bilinguals performed a facial expression identification task with emotion words in the task-irrelevant dimension, in either their first language (L1) or second language (L2). The investigation examined the automatic access of the emotional content in words appearing in more than one language. Significant congruency effects were present for both L1 and L2 emotion word processing. Furthermore, the magnitude of emotional face-word Stroop effect in the L1 task was greater as compared to the L2 task, indicating that in L1 participants could access the emotional information in words in a more reliable manner. In summary, these findings provide more support for the automatic access of emotional information in words in the bilinguals’ two languages as well as attenuated emotionality of L2 processing.

description:
In the Southern Brasília Orogen (south-eastern Brazil), a nappe system that represents the roots of a magmatic arc records HT-UHT metamorphic conditions in lower to mid-crustal rocks. It is divided into two segments by a major shear zone, of which the northern nappe hosts the most extreme metamorphism and has been targeted for most petrochronological studies. These rocks carry insights into the stages of orogeny, as well as the first direct evidence of the paleo-active margin basement, and time-constraint (1) a metamorphism related to the magmatic arc consolidation on the active margin at 670-640 Ma and (2) an enduring UHT event related to collision and decompression at 630-590 Ma. The southern nappe (Socorro Nappe) hosts felsic and mafic granulites, and migmatites that apparently describe a less extreme pressure-temperature setting and relatively younger ages. We found distinctive patterns pertaining the inner nappe and its outward boundaries (Embu Terrane and São Roque Domain). We present new U-Th-PbC monazite data and LA-ICPMS U-Pb and Lu-Hf systematics in zircon retrieved from granulites, migmatites and paragneisses, and partial results on conventional thermobarometry and thermodynamic modelling. Our data plot within the P-T range of upper amphibolite to granulite facies and describe mostly post-peak retrograde clockwise trajectories, with lesser conditions at the nappe boundaries. Temperature, textural context and anatexis are major controls on the preservation of monazite versus zircon records. The outer nappe tends to host prominent 750 Ma-old monazite, whereas in the inner nappe such ages are scarce and most prevalent in the zircon records.

description: Background:: Skin prick testing (SPT) is an important investigation in the evaluation of allergy to fungal pathogens. However, the background sensitivity to fungal allergens among healthy people in Uganda is unknown. Our aim was to assess the background prevalence of Aspergillus fumigatus SPT positivity in apparently healthy adults without known atopic disease in Uganda. Methods:: For this pilot study, we recruited 50 healthy volunteers using convenience sampling, 56% of whom were health workers. We performed the SPT for A. fumigatus according to manufacturer’s instructions. A wheal diameter of ⩾3 mm was considered positive. Results:: The prevalence of A. fumigatus skin positivity was 60% (30/50). Participants with a positive A. fumigatus SPT were significantly younger than those with a negative result [median age (years): 28 versus 35; p = 0.005]. Conclusion:: There is a high skin positivity against A. fumigatus among non-atopic healthy Ugandan adults. There is an urgent need to establish a normal wheal cut-off value for this population. SPT alone may be an unreliable test for the diagnosis of A. fumigatus associated allergic syndromes. More studies are needed to define the prevalence of A. fumigatus skin positivity among non-atopic healthy population in Africa.

description: ABSTRACT: The aim of this study was to investigate beneficiary panel characteristics associated with rheumatologists' prescribing of biologic DMARDs (bDMARDs) for older adults.In this retrospective observational study, we used Medicare Public Use Files (PUFs) to identify rheumatologists who met criteria for high-prescribing, defined as bDMARD prescription constituting ≥20% of their DMARD claims for beneficiaries ≥65 years of age. We first used descriptive analysis then multivariable regression model to test the association of high prescribing of bDMARDs with rheumatologists' panel size and beneficiary characteristics. In particular, we quantified the proportion of panel beneficiaries ≥75 years of age to assess how caring for an older panel correlate with prescribing of bDMARDs.We identified 3197 unique rheumatologists, of whom 405 (13%) met criteria for high prescribing of bDMARDs for Medicare beneficiaries ≥65 years of age. The high-prescribers provided care to 12% of study older adults, and yet accounted for 21% of bDMARD prescriptions for them. High prescribing of bDMARDs was associated with smaller panel size, and their beneficiaries were more likely to be non-black, ≥75 years of age, non-dual eligible, have diagnosis of CHF, however, less likely to have CKD.Rheumatologists differ in their prescribing of bDMARDs for older adults, and those caring for more beneficiaries ≥75 years of age are more likely to be high-prescribers. Older adults are more prone to the side-effects of bDMARDs and further investigation is warranted to understand drivers of differential prescribing behaviors to optimize use of these high-risk and high-cost medications.
title: Ambiguity of provenance studies in complex source-to-sink settings – sediment recycling, basement exhumation and signal mixing in the Schilfsandstein (Central European Basin)

description:
Provenance studies in the Central European Basin are challenged by the complex geology of source areas. The Variscan orogen represents a puzzle of Cadomian terranes, Variscan-aged domains and Palaeozoic sediments with Baltica-/Gondwana-derived detritus. The Caledonian-Fennoscandian source area comprises the Caledonian Belt, Archean to Neoproterozoic domains (Baltica), Variscan molasse sediments and Permo-Carboniferous igneous rocks.

The low-maturity Schilfsandstein (Stuttgart Formation), composed of first- and second-cycle sands, is an ideal candidate to evaluate provenance tools in a complex setting. Within a basin-scale study, subsurface facies maps, heavy minerals, and U-Pb zircon ages were applied to samples from Germany and onshore UK. Results show that the Schilfsandstein represents variable mixtures of recycled sediments and eroded basement. Heavy minerals are dominated by the Gt-Zr assemblage in North Germany (Fennoscandia), by the Ap-Zr-Ep assemblage in southern NW Germany (Rhenish Massif), and by Gt-Zr, Ap-Zr or Ap-Gt-Zr assemblages in Central and South Germany (Bohemian Massif, Vindelician Land). The clear discrimination of Variscan and Fennoscandian sources based on heavy minerals and subsurface facies maps is less constrained by zircon age spectra. Samples from North Germany either show a mix of Fennoscandian and Variscan spectra or typical Variscan spectra comparable to spectra of samples from Central and South Germany. The statistically identical age spectra of samples from North and South Germany (except UK) suggests mixing of source signals in Schilfsandstein rivers or recycling of Variscan molasse sediments in Fennoscandian catchment areas. The results show that complex source-to-sink settings need integrated approaches, individual provenance tools may lead to ambitious results.

description:
While the share of renewable energy in the electricity sector is steadily increasing, it has stagnated in the heat supply, despite the fact that in Berlin, for example, more than 40 % of the CO2 emissions are caused by the heating sector. Due to its ability to store large volumes in the underground while at the same time taking up little space on the surface, HT-ATES is particularly well suited for use in urban areas and can therefore contribute to the reduction of CO2 emissions. However, clogging of aquifer pores thus reducing the permeability, corrosion and mobilization of trace elements may be undesirable effects of HT-ATES.
Here, the Triassic limestones and the Jurassic sandstones were investigated as part of two Berlin ATES studies with the aim of (a) simulating the effect of HT-ATES operation on the carbonate aquifer by geochemical modelling, (b) identifying reactive mineral phases by systematic elemental analysis using a handheld XRF and (c) estimating the permeability and mobilization processes by column and batch experiments at elevated temperatures.
The results show that rapid analysis of drill cores at the drilling site provides important information on the presence of reactive mineral phases such as iron minerals, clay and carbonate content, and can therefore assist in filter placement. The mobilization of organic matter and trace elements has been observed in laboratory tests with siliciclastic sediments. The simulation of the HT-ATES operation in the saline carbonate aquifer, on the other hand, indicated carbonate precipitation due to temperature increase and degassing.

description: We discuss jet substructure in recombination algorithms for QCD jets and single jets from heavy particle decays. We demonstrate that the jet algorithm can introduce significant systematic effects into the substructure. By characterizing these systematic effects and the substructure from QCD, splash-in, and heavy particle decays, we identify a technique, pruning, to better identify heavy particle decays into single jets and distinguish them from QCD jets. Pruning removes protojets typical of soft, wide angle radiation, improves the mass resolution of jets reconstructing a heavy particle decay, and decreases the QCD background. We show that pruning provides significant improvements over unpruned jets in identifying top quarks and W bosons and separating them from a QCD background, and may be useful in a search for heavy particles.

description:
The Ouansimi copper mine is located south of the Kerdous inlier in the Western Anti-Atlas in Morocco. Neoproterozoic and Lower Cambrian sedimentary rocks record recurring transgressive and regression cycles by deposition of limestones, algae matts, or clastic rocks like conglomerates. The rocks are overprinted, likely due to the Variscan orogeny, resulting in an anticline formation showing internal large- and small-scale tectonic elements like folds, shearing, normal and reverse faults, as well as bend and drag folds.

The sedimentary rocks host mainly NW/SE striking veins with copper mineralisation, comprising e.g., chalcopyrite, chalcocite, sulfidic minerals, in combination with carbonates or quartz, as well as copper oxides (e.g., malachite) at the present-day surface. Processes, which lead to vein and ore formation and the possible tectonic influence are still not clearly understood. So far, the copper-bearing veins are mainly associated to the Variscan orogeny and hydrothermal influence. Field observations and structural measurements of stratigraphic bedding, fractures, and veins surrounding the Ouansimi mine are complemented with subsurface data, as well as transmitted and reflected light microscopy. Furthermore, microstructural observations are supplemented with cathodoluminescence microscopy.

This study will help to understand, if tectonic events beside the Variscan orogeny influenced the formation of veins and faults, as well as folds. Thus, the understanding of the regional geologic and tectonic processes of the Western Anti-Atlas region will be complemented.

description:
A major goal in exoplanet science is the search for planets with the right conditions to support liquid water. The habitability of a planet depends strongly on the composition of its atmosphere. Interiors and atmospheres of rocky planets are linked through feedback processes and evolve as a coupled system. In particular, volcanic outgassing shapes the atmospheric composition, but the exact composition of outgassed species not only depends on the volatile content and redox state of the mantle, but also on the current state of the atmosphere.

In an extensive parameter study of rocky exoplanets, we investigated the emergence of habitable surface conditions for a wide range of initial conditions, including the planet mass, interior structure, volatile content and redox state. The model accounts for the main mechanisms controlling the long-term evolution of stagnant-lid rocky planets (i.e. bodies without plate tectonics). It includes a large number of atmosphere-interior feedback processes, such as a CO2 weathering cycle, volcanic outgassing, a water cycle between ocean and atmosphere, greenhouse heating, as well as escape processes of H2.

We find that only a narrow range of the mantle redox state around the iron-wüstite buffer allows forming atmospheres that lead to long-term habitable conditions. At more oxidizing conditions, most planets instead end up in a hothouse greenhouse state (akin to Venus) due to strong CO2 outgassing. On the other hand, on planets with more reducing mantles, the amount of outgassed greenhouse gasses is often too low to keep the surface above the freezing point of water.

description:
The discovery and characterization of Earth-sized planets that are in, or near, a tidally-locked state are of crucial importance to understanding terrestrial planet evolution, and for which Venus is a clear analog. Exoplanetary science lies at the threshold of characterizing hundreds of terrestrial planetary atmospheres, thereby providing a statistical sample far greater than the limited inventory of terrestrial planetary atmospheres within the Solar System. However, the model-based approach for characterizing exoplanet atmospheres relies on Solar System data, resulting in our limited inventory being both foundational and critical atmospheric laboratories. Present terrestrial exoplanet demographics are heavily biased toward short-period planets, many of which are expected to be tidally locked, and also potentially runaway greenhouse candidates, similar to Venus. Here we describe the rise in the terrestrial exoplanet population and the study of tidal locking on climate simulations. These exoplanet studies are placed within the context of Venus, a local example of an Earth-sized, asynchronous rotator that is near the tidal locking limit. We describe the recent lessons learned regarding the dynamics of the Venusian atmosphere and how those lessons pertain to the evolution of our sibling planet. We discuss the implications of these lessons for exoplanet atmospheres and their detection with observations using JWST and other future facilities. We outline the need for a full characterization of the Venusian climate in order to achieve a full and robust interpretation of terrestrial planetary atmospheres.

description: We use the diagrammatic $T$-matrix approach to analyze the three-body scattering problem between two identical fermions and a third particle (which could be a different species of fermion or a boson). We calculate the s-wave dimer-atom scattering length for all mass ratios, and our results exactly match the results of Petrov. In particular, we list the exact dimer-atom scattering lengths for all available two-species Fermi-Fermi and Bose-Fermi mixtures. In addition, unlike that of the equal-mass particles case where the three-body scattering $T$-matrix decays monotonically as a function of the outgoing momentum, we show that, after an initial rapid drop, this function changes sign and becomes negative at large momenta and then decays slowly to zero when the mass ratio of the fermions to the third particle is higher than a critical value (around 6.5). As the mass ratio gets higher, modulations of the $T$-matrix become more apparent with multiple sign changes, related to the "fall of a particle to the center" phenomenon and to the emergence of three-body Efimov bound states.

description: Smart cities aim to utilize information technologies to improve efficiency and effectiveness of urban infrastructure and service delivery, and to advance the agenda of sustainability. Smart cities typically involve a variety of stakeholders with diverse agendas. In this study, we seek to explore incongruencies in stakeholder perspectives and identify how these are negotiated and reconciled. We examine the evolution of a smart city initiative in Bhubaneswar, an Indian city, over a three-year period, focusing on the divergence of stakeholder perspectives. We draw upon Technological Frames of Reference theory in identifying framing incongruencies present in the city's foundational frames. We understand these through the underlying frameworks of archetypal core constitutive values. We delineate mechanisms used to reconcile the incongruencies through building a shared foundational frame, boundary spanning, perspective seeking and cultural adaptation of technology-in-use. The study has implications for deliberately designed mechanisms that can aid inversion and negotiation of incongruent frames.

The papers are devoted to both membrane computing and biologically inspired process calculi, as well as to other related formalisms. The papers of this volume are selected by the programme committee due to their quality and relevance; they have defined an exciting programme highlighting interesting problems and stimulating the search for novel ways of describing related biological phenomena. In addition, we had an invited talk given by Luca Cardelli on a spatial process algebra for developmental biology. Membrane systems were introduced as a class of distributed parallel computing devices inspired by the observation that any biological system is a complex hierarchical structure, with a flow of materials and information that underlies their functioning. The emphasis is on the computational properties of the model, and it makes use of automata, languages, and complexity theoretic tools. On the other hand, certain calculi such as mobile ambients and brane calculi work with similar notions (compartments, membranes). These calculi are used to model and analyze the various biological systems. The workshop on Membrane Computing and Biologically Inspired Process Calculi brings together researchers working in these fields to present their recent work and discuss new ideas concerning the formalisms, their properties and relationships.

description: Excerpt from the report: Farmers pay more than 50 million dollars a year as premiums on about 1,250 million dollars of crop-hail insurance. This bulletin deals with the types of contracts that may he obtained, settlement of losses, and other important provisions of the contracts. Also included is a short sketch of the developments leading to the present status of crop-hail insurance. Of special use to farmers is a discussion, beginning on page 14, of how crop-hail insurance may he used along with Federal all-risk crop insurance. When crop prospects are average or better, crop-hail insurance is especially useful in protecting prospective net income.
title: Paleoseismic and -tectonic structures in Hamburg and Peissen (Schleswig-Holstein)

description:
Paleoseismic investigations in Hamburg and Peissen document paleo-earthquake structures, e.g. large clastic dykes, infill structures, complicated folds, fault-systems and vertical injections as larger structures. Smaller structures include special forms of diapirs, seismically induced soft-sediment deformation structures (SSDS), special flame structures, shear bands, among others. Plastic deformation is dominant in Hamburg, brittle deformation dominates in Peissen. The seismic deformations can be attributed to different mechanisms, e.g. compression as a result of seismic shock or sediment intrusion, liquefaction, fluidization, strain, shear stress, volume loss and subsequent collapse as a result of blowout activity. The observed structures show certain properties that allow a distinction from non-seismic forms (e.g. glacitectonic and periglacial deformation). Dyke structures are partly of Holocene age.

description: We report on experiments of drop impacting a hydrophobic micro-grid, of typical spacing a few tens of $μ$m. Above a threshold in impact speed, liquid emerges to the other side, forming micro-droplets of size about that of the grid holes. We propose a method to produce either a mono-disperse spray or a single tiny droplet of volume as small as a few picoliters corresponding to a volume division of the liquid drop by a factor of up to 10$^5$. We also discuss the discrepancy of the measured thresholds with that predicted by a balance between inertia and capillarity.

The effect of treating acute spinal cord injury with cardio-centric hemodynamic management and ethyl nitrite on the chronic outcome of blood pressure regulation
Creators: name: Duffy, Jennifer
Publisher: name: University of British Columbia
Year: 2023

description: Traumatic spinal cord injury (SCI) causes an initial injury followed by a protracted phase of spinal cord tissue hypoxia. This tissue hypoxia contributes to secondary injury, leading to worse motor and autonomic outcomes in the chronic setting. We have demonstrated that taking a cardio-centric approach to hemodynamic management following SCI by augmenting cardiac contractility and mean arterial pressure (MAP) with the B1-adrenoceptor agonist dobutamine (DOB), and further coupling DOB infusion with the inhalation of ethyl nitrite (ENO), an S-nitrosylating agent, is associated with improved spinal cord oxygenation in the acute phase post-SCI. Moreover, a major yet commonly over-looked outcome of chronic high-level spinal cord injury is the reduction in cardio-autonomic function due to damaged descending sympathetic tracts. As such, I aimed to determine the influence of a cardio-centric approach to hemodynamic management with added ENO inhalation following SCI on long term outcomes of blood pressure regulation. I hypothesized that treatment with DOB and ENO in the acute phase following SCI would mitigate secondary injury and improve cardiovascular outcomes in the chronic setting. To accomplish this, a total of 36 male Wistar rats underwent a T3 contusion injury (300 kdyn) and were assigned into 4 treatment groups: control (n=6), ENO (n=6), DOB (n=12), and combined DOB and ENO (n=12). At 12-weeks post-SCI, rodents were anesthetized with intravenous urethane (2.440.50 g/kg) and instrumented with a solid-state pressure transducer in the carotid artery to measure MAP. We observed a higher MAP in both DOB (113.611.4 mmHg; p=0.030) and ENO+DOB (116.714.6 mmHg; p=0.013) treated groups when compared with controls (94.6511.62 mmHg). The MAP of ENO treated animals (91.67.3 mmHg; p=0.97) was not different from controls. No difference in resting sympathetic nerve activity or -adrenergic receptor sensitivity was observed. Baroreflex sensitivity, quantified by the slope of the linear regression for % change in SNA and DBP, was greater in DOB (-0.9620.361 %/mmHg) vs. controls (-0.4330.297 %/mmHg; p=0.022) but not ENO+DOB (-0.7790.388 %/mmHg; p=0.616). Collectively, these data suggest that DOB treatment, alone or in combination with ENO, may improve systemic hemodynamics while DOB alone improves baroreflex sensitivity in the chronic high-thoracic SCI setting.

description:
The Lahn-Dill-Area, the Kellerwald and the Lindener Mark in the southeastern Rhenish Massif (Germany) are part of the Rhenohercynian Zone of the Central European Variscides. They contain various Devonian and Lower Carboniferous sandstones and greywackes, which differ significantly in their facies circumstances and fossil-content from surrounding autochthonous materials. U-Th-Pb- and Lu-Hf-analyses on detrital zircons of these allochthonous siliciclastic sediments indicate a provenance in the Saxothuringian zone and thus a Gondwanan hinterland. They show U-Pb-age clusters of ~530–700 Ma, ~1.8–2.2 Ga, ~2.5–2.7 Ga, and ~3.0–3.4 Ga. In contrast, samples from the autochthonous and par-autochthonous units of these areas show a provenance representative of Laurussia with debris primarily derived from Baltica and Avalonia with age clusters at ~400–450 Ma, 540–650 Ma, 1.0–1.2 Ga, ~1.4–1.5 Ga, ~1.7–2.2 Ga, and 2.3–2.9 Ga. These results, combined with own thin section analyses and geochemical data on volcanic rocks as well as revised biostratigraphy and paleobiogeography of Lower Devonian from the literature, led to the interpretation that the southeastern Rhenisch Massif is a nappe stack of Rhenohercynian and far transported Gondwana-related nappes. They were thrusted onto the autochthonous part of southern Laurussia during the Variscan orogeny by closing a wide Rheic Ocean.

description: We report a large set of experimental data which demonstrates that a simple yield stress fluid, i.e. which does not present aging or thixotropy, exhibits transient shear banding before reaching a steady state characterized by a homogeneous, linear velocity profile. The duration of the transient regime decreases as a power law with the applied shear rate $\dotγ$. This power law behavior, observed here in carbopol dispersions, does not depend on the gap width and on the boundary conditions for a given sample preparation. For $\dotγ\lesssim 0.1$ s$^{-1}$, heterogeneous flows could be observed for as long as 10$^5$ s. These local dynamics account for the ultraslow stress relaxation observed at low shear rates.

description:
Outcrop and sub-crop evidence from the Lower Triassic Sherwood Sandstone Group (SSG) suggests a northerly flowing braided river deposited pebble-rich red sandstones through several UK basins. Previous workers assume the sole source of this ‘Budleigh Salterton River System’ to be the Armorican Massif, based on dominantly metaquartzite pebble composition, paleoflow orientations and lithostratigraphy trend. However, a proximal to distal facies trend northwards from an Armorican Massif source should mean pebble-sized clasts decrease in abundance northwards, yet pebble-rich sandstones and conglomerates are seen through several basins with slight variations in composition, perhaps indicating that other topographic high areas adjacent to the river system also provide a source for the pebble clasts via tributary drainage systems. This study conducted fieldwork to collect data specifically surrounding clast inclusions pebble clasts, including clast size, abundance, and orientation, to determine if/where possible tributaries occur. Pebble abundance was plotted against distance using Matlab software, with a simple model inversion used to assess the distance from the source. Our results indicate a three source-model is most likely, suggesting local sources are present and significant contributors to the overall sediment budget. Using spatial distributions of pebble abundance, one tributary was likely located from the Welsh Massif and a second from a potential basin margin fault. These results contrast previous models, which suggest the majority of sediment was sourced from the Armorican Massif, and raise several questions about the distribution of Triassic sediment fairways across the UK.
