description:
The Karoo Supergroup of South Africa contains extremely rich palaeontological record, including evidence of the largest mass extinction in history, the end-Permian extinction (±251.9 Ma). The recovery of terrestrial ecosystems from this mass extinction is an active area of research and one of South Africa’s most important contributions to the field of palaeontology. The farm Driefontein 11 in the Free State Province preserves an Early Triassic (upper Olenekian) fossil lagerstattë in the Burgersdorp Formation of the Karoo’s Beaufort Group . Driefontein yields tens of thousands of body and trace fossils. These fossils range in size from sub-mm scale teeth and invertebrates to bones of large temnospondyls and archosauromorphs. Despite the importance of these fossils, the fauna of Driefontein remains incompletely known – reflecting the sheer numbers of specimens (+- 30 000 coprolites alone) as well as the fragmentary and/or fragile nature and microscopic size of many of the remains.  Here, we use a multiresolution (42µm to 1.14µm) approach with propagation phase contrast X-ray synchrotron micro computed tomography on the newly installed beamline, BM18, at the European Synchrotron and Radiation Facility, to investigate all trophic levels of Driefontein. We use this large dataset of high-resolution scans to investigate various aspects of organismal biology, including growth history, functional morphology, and comparative anatomy. This study contributes to our knowledge of the recovery of terrestrial ecosystems after the largest mass extinction in history, the end-Permian extinction, and highlights the importance of Driefontein 11 as a site for future research in the field of palaeontology

description: By extending our previous isobar model to the K^0Lambda isospin channel we investigate the properties of the K^0Lambda photo- and electroproduction at energies near threshold. It is found that the pseudovector (PV) coupling yields significantly larger cross section. Variation of the K_1 coupling constants has significant effect only on the PV model. The electromagnetic form factor of the neutral kaon K^0 is found to have a sizable effect on the longitudinal cross section of the K^0Lambda electroproduction near the threshold.

description:
 The Chatham Islands, situated on the eastern Chatham Rise ~800 km east of New Zealand, comprise two main (Chatham and Pitt) and many smaller islands. Collision of the oceanic Hikurangi Plateau with the Chatham Rise jammed the long-lived subduction system, causing Zealandia to separate from Gondwana. The breakup was accompanied by volcanism on the South Island of New Zealand, Hikurangi Plateau (Hikurangi seamounts) and Chatham Rise and islands, many of which were formed by the volcanism. The Late Cretaceous volcanism is characterized by HIMU (high time-integrated μ=238U/204Pb Mantle) endmember composition, which sensu stricto is defined by oceanic islands associated to deep-rooted mantle plumes. Consequently, an heritage of the HIMU source from the lower mantle transferred to the surface by a mantle plume is debated, but numerous alternative models have been proposed to explain the HIMU volcanism in Zealandia, including sub-continental lithospheric mantle modified by subduction or interaction with the partly subducted Hikurangi plateau. Our major and trace element analyses of 52 Cretaceous whole-rock samples from the Chatham Islands display characteristic HIMU trace element compositions, but the major element (MgO vs. CaO) and olivine composition indicate a predominantly pyroxenitic (or phlogopitic) rather than peridotitic source, which is usually associated with HIMU lavas. Further investigation on the composition of primitive melts, melting conditions and source lithologies will be used to evaluate the potential role of a mantle plume causing HIMU end member volcanism and separation of Zealandia from Antarctica in the Late Cretaceous.

description:
Although the burial of organic carbon in submarine fans and its importance for the carbon cycle have recently received growing attention, our understanding of the mechanisms at play is still lacking compared to other organic carbon storing environments.

Here, we present insights on the distribution of organic carbon throughout marine slope environments from the Arro System, Aínsa Basin (Spain). Evaluation of TOC content by C/S analysis from 82 samples show that there are distinct partitioning patterns of organic carbon between different depositional slope environments and mass transport complexes (MTC). Channel axes are relatively poor in organic carbon (average 0.1% TOC), while overbank deposits are relative enriched (average 0.49% TOC). Intraslope lobes show high variability between their sub-environments. Lobe axis deposits have an average TOC content of 0.13%, lobe fringe deposits 1.21% and the lobe distal fringe deposits 0.55%. Mass transport complexes have an average TOC content of 0.53 %. Integration of Hydrogen Indeces (HI) and Tmax, established by RockEval analyses, points towards our samples falling within the range between Type III and Type II kerogen (terrestrial and marine matter), while δC13 show a range between 24.5 and 26.5‰, indicating a predominantly terrestrial source.

Our study shows the partitioning of organic carbon across slope environments that are dominated by different depositional processes. The understanding of this variability is important as wrong assumptions about carbon content can be made from studies that ignore spatial differences and potentially lead to false interpretations of climatic/tectonic changes and estimations on carbon budgets.

description: Der Frauenanteil im neu gewählten 20. Bundestag ist wieder leicht gestiegen. 34,7 % der Abgeordneten sind weiblich – unter ihnen auch erstmalig zwei offen lebende trans Frauen. Der Anstieg lässt sich vor allem auf die Stimmenzuwächse bei den GRÜNEN zurückführen. Dennoch sind Frauen, verglichen mit der Gesamtbevölkerung, zahlenmäßig unterrepräsentiert. Das liegt an den Nominierungsverfahren und einer maskulinisierten Parteikultur, die Interessentinnen nach wie vor abschreckt und vor Vereinbarkeitsprobleme stellt. Die Analyse des Wahlergebnisses zeigt: Parteiinterne Wahllistenquotierungen bringen zwar mehr Frauen ins Parlament, doch nur parteiübergreifende Maßnahmen können zur Geschlechterparität führen. Ist ein Paritätsgesetz eine Lösung?

Statue, bear or rogue : ecological objects in Shakespeare and Jonson
Creators: name: Accili, Nola Vera
Publisher: name: University of British Columbia

description: Recent trends in literary ecocriticism have led to explicit politicized readings of historical texts and theatrical performances, including dramas by early modern playwrights William Shakespeare and Ben Jonson. Often imposing a contemporary ecological framework on the works in question, such “presentist” readings tend towards anachronism. While the current global environmental crisis gives such readings their urgency, it would be helpful that we develop a more historically and theoretically nuanced understanding of early modern ecologies. An approach that embraces both environmental and art histories can help illuminate the plays to this end. In particular, a renewed focus on the intersections among character, theatrical space, sculpture, painting, architecture, and animal ecologies can provide a fuller understanding of an early modern “green” consciousness. In this way, we may come to an accurate understanding of ecological ideas that circulated in the time of Shakespeare and Jonson—without politicizing our analyses to accord with a current agenda. A close examination of Elizabethan and Jacobean characters from a perspective that sees them as integrated human and non-human entities, or what I call ecological objects, can teach us a great deal about the early modern “environment.” As agentic beings situated in “nature” defined as a hybrid entity of wild and manufactured elements, characters embody facets of an early modern fascination with the organic and the aesthetic: nature and culture combined. In the philosophical language of today, this bridging of contradictory phenomena has been described as “dark ecology.” Shakespeare’s Midsummer Night’s Dream and Winter’s Tale, along with Jonson’s Masque of Oberon the Fairy Prince and Bartholomew Fair, provide evidence of such an historical eco-consciousness that has reverberations in the contemporary world. Understanding theatrical characters as depictions of historical ecologies can elicit in spectators a renewed sense of praxis (e.g., as thinking and/or feeling) and, ultimately, stewardship of Planet Earth.

description: We assess the most plausible scenarios for generating large amounts of dust in high-z quasars (QSOs) on the basis of observationally derived physical properties of QSOs at z > 6. We use a chemical evolution model to compute the temporal progression of quantities, such as the amount of dust and gas, stellar masses, star formation rates (SFRs) and the metallicity for various combinations of the initial mass function (IMF), the mass of the galaxy, dust production efficiencies, and the degree of dust destruction in the ISM. We investigate the influence of the SFR on the evolution of these quantities, and determine the earliest epochs at which agreement with observations can be achieved. We apply the obtained results to individual QSOs at z > 6. We find that large quantities of dust can be generated rapidly as early as 30 Myr after the onset of the starburst when the SFR of the starburst is > 10^3 M_sun yr^(-1). The amount of dust and several other physical quantities of individual QSOs at z > 6 are satisfactorily reproduced by models at epochs 30, 70, 100, and 170 Myr for galaxies with initial gas masses of 1-3 x 10^11 M_sun. The best agreement with observations is obtained with top-heavy IMFs. A sizable dust contribution from supernovae (SNe) is however required, while at these epochs dust production by asymptotic giant branch (AGB) stars is negligible. Moderate dust destruction in the ISM can be accommodated.

description:
The Cenozoic uplift of the Tibetan Plateau leads to eastward lateral extrusion of fault-bounded blocks, which caused large surface uplift. To the northeast of the Tibetan Plateau, the development of the particular fluvial incision landscape on the internally stable Ordos Loess Plateau reflects the lateral extrusion and thrust loading by the adjacent Liupanshan Mts. in the west. In this study, we investigated the climate-mediated temporal evolution of surface uplift and the effect of activity along confining faults on the morphological evolution of the Ordos Loess Plateau by fieldwork, morphological analysis and integration of results from numerous previous studies. Field surveys show that the boundaries of the Ordos Loess Plateau are still tectonically active and fluvial channels are in a state of morphological disequilibrium, with steep channel segments towards the Weihe Graben and meandering low-gradient rivers in the central Ordos Loess Plateau. Morphological analysis shows that the shape of the longitudinal channel profile is straight and deviates from typical longitudinal channel profiles and the degree of erosion and plateau incision is more pronounced in the southeastern Ordos Loess Plateau. We conclude that the northeastern expansion of the Tibetan Plateau activated the boundary faults around the tectonically stable, craton-like Ordos Loess Plateau, which caused the drainage basins to tilt towards the overthrusting Liupanshan Mts in the southwest. The drainage systems reorganized to a principal southern flow direction towards the Weihe Graben caused by the ongoing E-W shortening and ca. N-S extension and thereby progressively incising in the Ordos Loess Plateau.

description: The equation of state and the phase diagram in two-flavor QCD are investigated by the Polyakov-loop extended Nambu--Jona-Lasinio (PNJL) model with an entanglement vertex between the chiral condensate and the Polyakov-loop. The entanglement-PNJL (EPNJL) model reproduces LQCD data at zero and finite chemical potential better than the PNJL model. Hadronic degrees of freedom are taken into account by the free-hadron-gas (FHG) model with the volume-exclusion effect due to the hadron generation. The EPNJL+FHG model improves agreement of the EPNJL model with LQCD data particularly at small temperature. The quarkyonic phase survives, even if the correlation between the chiral condensate and the Polyakov loop is strong and hadron degrees of freedom are taken into account. However, the location of the quarkyonic phase is sensitive to the strength of the volume exclusion.

description:
The Cenozoic cooling that occurred over the past 50 Ma is accompanied by an increase of Mg/Ca ratio in seawater. How this change in seawater chemistry is linked to climate change is still disputed. Mg isotope ratios of seawater could distinguish several possible causes including dolomitization, authigenic clay formation and changes in rates of silicate- and carbonate weathering. Former reconstructions of Mg isotope ratios of paleo-seawater are based on foraminifera, corals or carbonate muds, which however yield conflicting results. Here we assess the suitability of the bivalve Glycymeris as an archive for paleo-seawater δ26Mg (the standardized 26Mg/24Mg ratio). Their potential as geochemical archive advantage arises from their strong evolutionary conservatism, thick shells and a fossil record dating back to the Early Cretaceous. We report Mg isotope signatures of shells of three recent Glycymeris species from the Adriatic Sea that show an increasing fractionation with increasing ontogenetic age, a property that we use to determine δ26Mg of paleo-seawater from fossil Glycymeris specimens.

description:
Carbonatites are igneous rocks with significant concentrations of rare earth elements (REEs) and other important metals. Despite their economic potential, their origin and evolution are poorly understood. Crustal contamination can significantly modify REE abundance in carbonatites. The current study provides new petrographic, geochemical, and stable isotopic insight into the processes that led to the formation of high field strength element (HFSE) bearing carbonatites i.e. pyrochlore-calcite carbonatite, and rare earth element (REE) bearing carbonatite i.e. quartz-ankerite-calcite carbonatite in the Nooitgedacht Volcano.

The Nooitgedacht Volcano is an oval-shaped body with approximately a 3 km diameter situated in the Kaapvaal Craton in South Africa. It comprises mostly calcite carbonatite with enclosures of dolomite carbonatite. Petrographically, calcite carbonatite is divided into pyrochlore-calcite carbonatite and quartz-ankerite-calcite carbonatite. The mineral assemblage of pyrochlore, apatite, magnetite, and forsterite indicate an ortho-magmatic origin while the mineral association of monazite, ankerite, and quartz represents a post-magmatic/ hydrothermal origin for the quartz-ankerite calcite carbonatite. Stable isotope data (δ13C = -5 to -4) and (δ18O = +7 to +16) indicate a primary mantle source for the carbonatite with subsequent crustal contamination.

In summary, petrographic, mineralogical, geochemical, and isotopic data provide significant insight into the evolution of the Nooitgedacht Volcano, highlighting a complex history of magmatic differentiation, mineral fractionation, and crustal contamination.

description:

Soil moisture is a key metric to assess soil health. Water held in the shallow subsurface between soil particles enables various biogeochemical and hydrological processes indispensable to soil functions. Potential soil moisture deficit may rise the irrigation demands, which further exacerbates the stress on the water supply. The changes in soil moisture can impact climate, further amplifying the climatic anomalies and intensifying extreme weather events. Thus, understanding soil moisture and its dynamics over time are of broad scientifical interest and practical implications.

Despite the vital importance of soil moisture, it still lacks sufficient means to properly assess the parameter at a regional scale, which is an essential research dimension for addressing practical issues in the agricultural and environmental sectors.

Ambient noise seismology provides new possibilities to infer subsurface changes in a real-time, non-intrusive, and cost-effective manner. In this study, we map the temporal variations in soil moisture for the great Alpine region and the Italy peninsular with ambient seismic noise. It is the first time that the seismic method has been applied to map water resources at a regional scale using an ordinary national seismic network set-up. The seismic method helps in bridging the resolution gap between current pointwise (e.g., tensio-, electrical- and neutron-meter) and global (e.g., satellite-based remote sensing) investigations, providing complementary information for both scientific research and public decision-making.

description: In solid-state circuit QED system, we extend the previous study of generating and stabilizing two-qubit Bell state [Phys. Rev. A 82, 032335 (2010)], to three-qubit GHZ state. In dispersive regime, we employ the homodyne joint readout for multiple qubits to infer the state for further processing, and in particular use it to stabilize the state directly by means of an alternate-flip-interrupted Zeno (AFIZ) scheme. Moreover, the state-of-the-art feedback action based on the filtered current enables not only a deterministic generation of the pre-GHZ state in the initial stage, but also a fast recovery from the environment-caused degradation in the later stabilization process. We show that the proposed scheme can maintain the state with high fidelity if the efficient quantum measurement and rapid single-qubit rotations are available.

We investigate the possible supersymmetric effects on this process and compare our standard model numerical results with those in previous work. We present the leading-order and QCD next-to-leading-order corrected total cross sections and the distributions of the transverse momenta of the final electron, the light neutral Higgs boson, and jet in the minimal supersymmetric standard model. Our results show that the scale dependence of the leading-order cross section is obviously reduced by the QCD next-to-leading-order corrections. The K factor of the QCD correction to the total cross section at the large hadron-electron collider varies from 0.893 to 1.048 when the factorization/renormalization scale $μ$ goes up from $0.2 m_Z$ to $3.8 m_Z$ in our chosen parameter space.

description:
The building and construction sector accounts for a significant proportion of current anthropogenic CO2 emissions. Reducing the carbon footprint of building materials is difficult because some process-related CO2 emissions cannot be avoided. While the industry is developing methods to reduce its emissions by capturing CO2 from flue gas streams, this study investigates an alternative mechanism to reduce the carbon footprint of building materials, namely the incorporation of olivine into building materials such as façade plaster. Olivine is susceptible to weathering and reacts with CO2 to form magnesium carbonate and silica.

In collaboration with the company Knauf Gips KG, an outdoor test facility will be built to monitor the mineralogical changes in olivine façade plaster under natural weathering conditions over a period of 18 months. In parallel, laboratory experiments will be carried out to accelerate the weathering process by continuous artificial weathering of the plaster samples. Fluids will be regularly sampled and analysed to detect potential environmental hazards, such as the release of nickel and chromium into the environment. All plaster samples will be analysed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) to identify mineralogical and structural changes during the experiments. The extent of CO2 mineralisation will be assessed based on mass balance calculations with the experimental reactants and their products. A sustainability assessment of the whole value chain will be carried out to determine whether olivine in building materials can effectively contribute to offsetting the CO2 emissions of the construction industry.
Optimized Effective Potential Model for the Double Perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6

description: In attempt to explore half-metallic properties of the double perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6, we construct an effective low-energy model, which describes the behavior of the t2g-states of these compounds. All parameters of such model are derived rigorously on the basis of first-principles electronic structure calculations. In order to solve this model we employ the optimized effective potential method and treat the correlation interactions in the random phase approximation. Although correlation interactions considerably reduce the intraatomic exchange splitting in comparison with the Hartree-Fock method, this splitting still substantially exceeds the typical values obtained in the local-spin-density approximation (LSDA), which alters many predictions based on the LSDA. Our main results are summarized as follows: (i) all ferromagnetic states are expected to be half-metallic. However, their energies are generally higher than those of the ferrimagnetic ordering between V- and Mo/Tc-sites (except Sr2VMoO6); (ii) all ferrimagnetic states are metallic (except fully insulating Y2VTcO6) and no half-metallic antiferromagnetism has been found; (iii) moreover, many of the ferrimagnetic structures appear to be unstable with respect to the spin-spiral alignment. Thus, the true magnetic ground state of the most of these systems is expected to be more complex. In addition, we discuss several methodological issues related to the nonuniqueness of the effective potential for the magnetic half-metallic and insulating states.

description:
Defining patterns of environmental or ecological change on different spatio-temporal scales is key to tracking and addressing present and future biodiversity changes, which is particularly important considering the rapidly changing climate scenarios. Climate change in the arctic means shrinking glaciers, drying out of peatland and carbon release, more frequent forest and peatland fires, and thawing permafrost. Alaska hosts some of the largest Boreal peatlands and forests; however, little is known about the fine-scale dynamics of these ecosystems particularly over the last millennia, which is key to making effective management decisions into the uncertain future. In this presentation, I will be presenting the results so far from an ongoing work that employs different lines of evidence (pollen, non-pollen palynomorphs, charcoal, and tephra) from two peatland sites in southern Alaska to reveal interactions between vegetation, fire and climate in the area during the last millennia, as well as the potential influence of humans and volcanic eruptions on these interactions.

« Grand Lyon » des plans contre « Grand Lyon » des gens ? Histoire d’une autoroute urbaine avortée, le boulevard des Etats-Unis dans l’agglomération lyonnaise, années 1970-années 1990

description: Si Lyon est connue comme la seule ville française entièrement traversée par une autoroute, plusieurs projets d’autoroutes urbaines sont abandonnés ou profondément modifiés à cause de mobilisations collectives au cours des années 1970 à 1990. Parmi ceux-ci, le réaménagement du boulevard des Etats-Unis, artère intercommunale qui relie Lyon à sa banlieue Sud-Est Vénissieux, se prête bien à une analyse historique car il connaît deux moments conflictuels, au début des années 1970 et au début des années 1990. Une approche comparée de ces deux moments permet de mettre en évidence les stratégies de centralité mobilisées par les divers acteurs, dont les conflits révèlent une double opposition : d’échelles, entre promotion de l’intercommunalité et défense du cadre de vie du quartier, mais aussi au sujet des processus de concertation, avec un décalage patent entre la planification par des techniciens et les attentes des populations réunies au sein d’un puissant comité de quartier. Les archives publiques et associatives sur ces conflits permettent de réfléchir sur les acteurs, les arguments mobilisés (environnementaux et politiques/institutionnels) et les aménagements concrets qui font suite aux conflits et témoignent de nouvelles stratégies des aménageurs.

description:
Triple oxygen isotope (Δ'17O) analysis has recently be shown to be a powerful tool for identifying metabolic oxygen signatures in mammalian tooth enamel (Pack et al., 2013; Feng et al., 2022). Atmospheric O2 is consumed by mammals for metabolic oxidation. The low triple oxygen isotope (Δ'17O) composition of air O2 serves as a natural tracer for identifying metabolic oxygen in body water. Bioapatite precipitates in isotopic equilibrium with its parental body water and consequently records information on the air O2. The Δ'17O of atmospheric O2 is directly linked to pCO2 and gross primary production, hence fossil teeth can be used for paleo- pCO2 reconstructions.

To provide a modern baseline for this approach, we measured 128 individual mammal teeth for their bioapatite Δ'17O by automatic BrF5 laser fluorination. The sample set includes diverse body size with a body mass range from 2 g to 6000 kg and physiology from different habitats. Taxon-specific oxygen mass balance models are developed for resolving principal dependencies and relationships.

The mass balance modelled data for all species agree within uncertainty with the measured data. The results show that Δ'17O not only correlates with body mass, but also with initial oxygen anomalies of inhaled air O2, which allows for pCO2 reconstruction on terrestrial mammalian tooth enamel. This documents the potential of tooth enamel Δ'17O analysis for metabolic rates of extinct vertebrates and paleoclimate reconstructions, especially for small mammals (Mb < 1 kg).

Block-Conditional Missing at Random Models for Missing Data

description: Two major ideas in the analysis of missing data are (a) the EM algorithm [Dempster, Laird and Rubin, J. Roy. Statist. Soc. Ser. B 39 (1977) 1--38] for maximum likelihood (ML) estimation, and (b) the formulation of models for the joint distribution of the data ${Z}$ and missing data indicators ${M}$, and associated "missing at random"; (MAR) condition under which a model for ${M}$ is unnecessary [Rubin, Biometrika 63 (1976) 581--592]. Most previous work has treated ${Z}$ and ${M}$ as single blocks, yielding selection or pattern-mixture models depending on how their joint distribution is factorized. This paper explores "block-sequential"; models that interleave subsets of the variables and their missing data indicators, and then make parameter restrictions based on assumptions in each block. These include models that are not MAR. We examine a subclass of block-sequential models we call block-conditional MAR (BCMAR) models, and an associated block-monotone reduced likelihood strategy that typically yields consistent estimates by selectively discarding some data. Alternatively, full ML estimation can often be achieved via the EM algorithm. We examine in some detail BCMAR models for the case of two multinomially distributed categorical variables, and a two block structure where the first block is categorical and the second block arises from a (possibly multivariate) exponential family distribution.

Role of myostatin signaling in human trophoblast cell invasion

description: Placental insufficiency disorders, including preeclampsia (PET), intrauterine growth restriction (IUGR) and preterm labor (PTL), are major obstetric complications that can have devastating effects on both the mother and the fetus. These syndromes share a common phenomenon of poor placental trophoblast cell invasion into the uterine tissue. To date there are no effective treatments for these illnesses. Placental invasion is controlled by many hormones and growth factors, among which the transforming growth factor (TGF)-β superfamily is a well-known regulator. Myostatin (MSTN) is a TGF-β superfamily member recognized for its important role in muscle growth control. Recently, MSTN was shown to be secreted and functioning in the placenta. In addition, MSTN serum and/or placental levels were found to be upregulated in common pregnancy complications including PET and IUGR. Yet, the role of MSTN in placental biology is poorly understood. In this study, I confirmed the positive effect of MSTN treatment on human trophoblast invasion and performed mRNA sequencing on control and MSTN-treated primary trophoblast cells (n=5). This analysis identified 610 differentially expressed genes (DEGs) with a false discovery rate <0.05, of which 380 were upregulated and 230 genes were downregulated. DEGs were highly enriched in epithelial mesenchymal transition (EMT) genes, among which serine protease inhibitor E2 (SERPINE2), plasminogen activator inhibitor-1 (PAI-1), SRY-Box Transcription Factor 4 (SOX4) and the cell adhesion molecule N-cadherin (N-Cad) were validated using RT-qPCR and Western blot. I then demonstrated that each of those genes was involved in MSTN-induced trophoblast cell invasion. Finally, I investigated the upstream signaling and found that MSTN induced upregulation of SERPINE2, PAI-1 and N-Cad via the canonical ALK4/5-SMAD2/3/4 signaling pathway. iv However, SMAD2 does not appear to be involved in MSTN-induced PAI-1 upregulation. In addition, SOX4 was involved in MSTN-induced SERPINE2 upregulation. Collectively, the current study deciphers the underlying molecular mechanisms involved in MSTN-induced human trophoblast cell invasion and provides insight into the functional consequences of its dysregulation in placental insufficiency disorders.

description: We report very low temperature magnetoconductance DeltaG measurements on graphene devices with the magnetic field H applied parallel to the carbon sheet. The DeltaG(H) signal depends on the gate voltage Vg and its sign is related with the universal conductance fluctuations. When the magnetic field is swept at fast rates, DeltaG displays hysteresis loops evident for different sizes and at different transport regimes of the devices. We attribute this to the magnetization reversal of paramagnetic centres in graphene layer, which might originate from defects in our devices.

description:
The Namaqua Metamorphic Complex (NMC) forms a basement unit of the Grenvillian-Kibaran collisional orogen in southern Namibia and South Africa. The Aus Crystalline Complex is a terrane within the NMC and consists, predominantly, of gneisses, granites, metavolcanites, and metasediments. The objective of our study is to generate new knowledge about crustal evolution during the Kibaran orogeny using age dating and whole rock geochemistry of various basement units of the crystalline complex around Aus.

Outcropping basement rocks were Aampled in the Namib Desert, southwestern Namibia, east of the coastal town of Lüderitz, within a 20 km radius around Aus. Rock types encountered included granulites, gneisses, charnockites, granites, and pegmatites. Geochemical and geochronological analyses were performed to gain information on the timing of crystallisation and crust production processes, using U-Pb dating on magmatic zircons with LA-ICP-MS. Analysed zircon grains are often complex, U-Pb ages range from 1700 Ma to c. 700 Ma. The oldest rock is a charnockite showing an age of intrusion of c. 1700 Ma, which represents a Palaeoproterozoic part of the cratonic basement. U-Pb zircon ages of the gneisses point to protolith ages of c. 1155 Ma – 1145 Ma. This coincides with a major tectono-magmatic event in the NMC, which occurred in a time span of c. 1190 - 980 Ma. Such processes led to the amalgamation of the supercontinent Rodinia in late Mesoproterozoic time. A younger suite of granitoids (c. 700 Ma) is most probably related to Rodinia dispersal.
