description: The formulation of hypermultiplets that has been developed for 5-dimensional matter multiplets is by dimensional reductions translated into the appropriate spinor language for 6 and 4 dimensions. We also treat the theories without actions that have the geometrical structure of hypercomplex geometry. The latter is the generalization of hyper-Kaehler geometry that does not require a Hermitian metric and hence corresponds to field equations without action. The translation tables of this paper allow the direct application of superconformal tensor calculus for the hypermultiplets using the available Weyl multiplets in 6 and 4 dimensions. Furthermore, the hypermultiplets in 3 dimensions that result from reduction of vector multiplets in 4 dimensions are considered, leading to a superconformal formulation of the c-map and an expression for the main geometric quantities of the hyper-Kaehler manifolds in the image of this map.

description: A detailed numerical study of the real space configuration of vortices in disordered superconductors using 2D London-Langevin model is presented. The magnetic field $B$ is varied between 0 and $B_{c2}$ for various pinning strengths $Δ$. For weak pinning, an inhomogeneous disordered vortex matter is observed, in which the topologically ordered vortex lattice survives in large domains. The majority of the dislocations in this state are confined to the grain boundaries/domain walls. Such quasi-ordered configurations are observed in the intermediate fields, and we refer it as the domain regime (DR). The DR is distinct from the low-field and the high-fields amorphous regimes which are characterized by a homogeneous distribution of defects over the entire system. Analysis of the real space configuration suggests domain wall roughening as a possible mechanism for the crossover from the DR to the high-field amorphous regime. The DR also shows a sharp crossover to the high temperature vortex liquid phase. The domain size distribution and the roughness exponent of the lattice in the DR are also calculated. The results are compared with some of the recent Bitter decoration experiments.

description: The longitudinal polarization of fermions (tops and taus) produced in sfermion decays to neutralinos or charginos can be a useful tool for the determination of SUSY parameters. We discuss this fermion polarization in the context of the MSSM with complex parameters. We show that the dependence on CP-violating phases can be large and that the fermion polarization may hence be used as a sensitive probe of CP phases in the MSSM.

title: The most ancient platanistid: An insight into the early evolutionary history of the dolphin group

The fossil record of Platanistidae (Indian river dolphins and extinct partially marine relatives, Early Miocene to today) is suggestive of an early radiation of the group reflected in the diversification of the skull morphology, and a wide distribution in the Old World and New World during the Miocene that dropped coincidentally with the appearance of delphinoids (pelagic dolphins and closest relatives) in the Late Miocene. River dolphin radiation is correlated with the rise of shallow epicontinental seas, as a result of high sea levels during the Middle Miocene. Their stem group is interpreted to have remained in marine areas, serving as ancestor to species entering and adapting to freshwater environments. Here, a new Platanistidae skull is described from deep-marine sediments from the lower Miocene of Austria with an age of ca. 22 Ma. Morphological comparison with other dolphins provides insights into ecology and evolution through dentition, and cranial asymmetry related to hunting and navigating in aquatic environments. The skull belongs to a single-rooted homodont dolphin, known as a characteristic of the Platanistidae, in contrast to heterodont dentition in their platanistoid ancestors. According to our preliminary phylogenetic analysis, the skull represents the most ancient member known to date of the Platanistidae, predating all previous early records by 2 to 5 million years, and documenting a pelagic habitat adaptation.

description: Biological active materials such as bacterial biofilms and eukaryotic cells thrive in confined micro-spaces. Here, we show through numerical simulations that confinement can serve as a mechanical guidance to achieve distinct modes of collective invasion when combined with growth dynamics and the intrinsic activity of biological materials. We assess the dynamics of the growing interface and classify these collective modes of invasion based on the activity of the constituent particles of the growing matter. While at small and moderate activities the active material grows as a coherent unit, we find that blobs of active material collectively detach from the cohort above a well-defined activity threshold. We further characterise the mechanical mechanisms underlying the crossovers between different modes of invasion and quantify their impact on the overall invasion speed.

description: Many persistent organic pollutants, such as polychlorinated biphenyls (PCBs), have high immunomodulating potentials. Exposure to them, in combination with virus infections, has been shown to aggravate outcomes of the infection, leading to increased viral titers and host mortality. Expression of immune-related microRNA (miR) signaling pathways (by host and/or virus) have been shown to be important in determining these outcomes; there is some evidence to suggest pollutants can cause dysregulation of miRNAs. It was thus hypothesized here that modulation of miRNAs (and associated cytokine genes) by pollutants exerts negative effects during viral infections. To test this, an in vitro study on chicken embryo fibroblasts (CEF) exposed to a PCB mixture (Aroclor 1260) and then stimulated with a synthetic RNA virus (poly(I:C)) or infected with a lymphoma-causing DNA virus (Gallid Herpes Virus 2 [GaHV-2]) was conducted. Using quantitative real-time PCR, expression patterns for mir-155, pro-inflammatory TNFα and IL-8, transcription factor NF-κB1, and anti-inflammatory IL-4 were investigated 8, 12, and 18 h after virus activation. The study showed that Aroclor1260 modulated mir-155 expression, such that a down-regulation of mir-155 in poly(I:C)-treated CEF was seen up to 12 h. Aroclor1260 exposure also increased the mRNA expression of pro-inflammatory genes after 8 h in poly(I:C)-treated cells, but levels in GaHV-2-infected cells were unaffected. In contrast to with Aroclor1260/poly(I:C), Aroclor1260/GaHV-2-infected cells displayed an increase in mir-155 levels after 12 h compared to levels seen with either individual treatment. While after 12 h expression of most evaluated genes was down-regulated (independent of treatment regimen), by 18 h, up-regulation was evident again. In conclusion, this study added evidence that mir-155 signaling represents a sensitive pathway to chemically-induced immunomodulation and indicated that PCBs can modulate highly-regulated innate immune system signaling pathways important in determining host immune response outcomes during viral infections.

description: Exomoons represent a crucial missing puzzle piece in our efforts to understand extrasolar planetary systems. To address this deficiency, we here describe an exomoon survey of 70 cool, giant transiting exoplanet candidates found by Kepler. We identify only one which exhibits a moon-like signal that passes a battery of vetting tests: Kepler-1708 b. We show that Kepler-1708 b is a statistically validated Jupiter-sized planet orbiting a Sun-like quiescent star at ~1.6AU. The signal of the exomoon candidate, Kepler-1708 b-i, is a 4.8-sigma effect and is persistent across different instrumental detrending methods, with a 1% false-positive probability via injection-recovery. Kepler-1708 b-i is ~2.6 Earth radii and is located in an approximately coplanar orbit at ~12 planetary radii from its ~1.6AU Jupiter-sized host. Future observations will be necessary to validate or reject the candidate.

description: KAUST, Saudi Arabia

 Late Jurassic carbonates of Saudi Arabia contain some of the the world’s most prolific oil-producing strata in super giant reservoirs. Small scale stratigraphic architecture and associated property and flow heterogeneities are poorly resolved in the inter-well scale of hundreds of meters because such heterogeneities are subseismic and beyond penetration of borehole logs. This blindspot leads to oversimplified reservoir models and simulations. However, analogous strata is spectacularly exposed in the outcrops along the Tuwaiq Mountain Escarpment, central Saudi Arabia. This virtual field trip focuses on the Late Jurassic Hanifa Formation outcrops at Wadi Birk, central Saudi Arabia with an objective to highlight and display interwell scale heterogeneities associated with depositional architecture. The drone-survey involved two-stages: (1) a complete (4x4 km2) nadir-view survey with a fixed-wings-drone (Wingtra), (2) high-resolution survey of cliff’s along mesas (>20 km) with DJI-M600 (hexacopter), where the drones were equipped with a Sony-RX1R-ii-42 MP camera. The imagery and Ground Control Points (laid before survey and accurately measured) were used to develop georeferenced high-resolution (cm-scale) 3D digital outcrop model (DOM) with Pix4D. The DOM is interpreted with VRGS to capture the formation architecture and dimensionality. The DOM is supplemented with geological (measured section, thin sections), petrophysical (spectral gamma ray), and geophysical (ground-penetrating-radar and shallow-seismic) datasets. The observations and results will be used as input into high-resolution static reservoir models to address the gap of our understanding in inter-well scale heterogeneities of similar subsurface hydrocarbon reservoirs.

description: Per quanto strano possa sembrare, in un Paese come l'Italia, dove insediamento e civiltà hanno una storia plurimillenaria, vi sono ancora piccole individualità subregionali che non sono "territorio", nel pieno senso tecnico del termine. Si tratta di "vuoti relativi" in cui la presa di coscienza delle magrissime risorse locali da parte delle unità sociali, insediate ai loro margini, non si esprime "attivamente", cioè attraverso la vera e propria costruzione di "ambienti volontaristicamente ordinati", e, quindi, con l'incorporazione di alte quantità di lavoro umano per unità di superficie, in forme fisse e di manutenzione, ma in adattamenti piuttosto "passivi", ossia con l'intervento minimo, come il pascolo brado e l'utilizzo delle poche specie arboree e arbustive. Ciò non significa assenza totale di elementi antropici: per esempio il pascolo e gli usi ad esso relativi, operano selettivamente sulla flora e sulla fauna, creano alcune forme di insediamento stagionale, nonché precario, impediscono attualmente il formarsi di centri abitati di grande consistenza, ma anche quello di vere e proprie case coloniche sparse.

description: Self-diffusion of a polymer chain in a melt is studied by Monte Carlo simulations of the bond fluctuation model, where only the excluded volume interaction is taken into account. Polymer chains, each of which consists of $N$ segments, are located on an $L \times L \times L$ simple cubic lattice under periodic boundary conditions, where each segment occupies $2 \times 2 \times 2$ unit cells. The results for $N=32, 48, 64, 96, 128, 192, 256, 384$ and 512 at the volume fraction $ϕ\simeq 0.5$ are reported, where $L = 128$ for $N \leq 256$ and L=192 for $N \geq 384$. The $N$-dependence of the self-diffusion constant $D$ is examined. Here, $D$ is estimated from the mean square displacements of the center of mass of a single polymer chain at the times larger than the longest relaxation time. From the data for $N = 256$, 384 and 512, the apparent exponent $x_{\rm d}$, which describes the apparent power law dependence of $D$ on $N$ as $D \propto N^{- x_{\rm d}}$, is estimated as $x_{\rm d} \simeq 2.4$. The ratio $D τ/ < R_{\rm e}^{2} >$ seems to be a constant for $N = 192, 256, 384$ and 512, where $τ$ and $$ denote the longest relaxation time and the mean square end-to-end distance, respectively.

description: The University of Debrecen, Faculty of Engineering, has been conducting a research program in geothermal energy since 2008. This program enabled me to devise an analytical study of the monetary and non-monetary criteria of geothermal projects. The monetary criteria of a region or a location for geothermal energy production cover the investment costs of the surface installations and the cost of the drillings. Non-monetary criteria include the geological and geothermal evaluations of a reservoir and the evaluation of consumer potential. This paper represents a small part of the larger study and focuses on consumer potential.

Alkalinity, the excess of bases over acids, is a frequently used conservative variable in Biogeochemistry and Oceanography to calculate carbonate system parameters and estimate the oceans susceptibility to acidification. On timescales smaller than the residence time of the bicarbonate ion, the major contributor to ocean alkalinity, this budget should be at steady state, implying input and output to be balanced. Despite its importance and incorporation into earth system models, the classic ocean alkalinity budget leaves an imbalance of 27 Tmol(eq)/a, that is close to the whole input term (32 Tmol(eq)/a of riverine dissolved inorganic carbon, DIC) and almost half of the output by carbonate burial (60 Tmol(eq)/a). Marine processes and transformations narrow the budget by contributing 12 Tmol(eq)/a. The residual imbalance can potentially be closed by including the so far unaccounted delivery of riverine detrital carbonates (PIC) to the ocean, as these carbonate minerals will either dissolve and contribute to the input term, or should be subtracted from the burial term. PIC seems a largely overlooked variable of riverine systems, and global estimates range from 0.04 – 1 wt% (1.0 – 25.1 Tmol(eq)/a) relying on small datasets or regionally restricted estimates. Preliminary results from a new global database of riverine suspended matter geochemistry, as well as estimates using global soil composition, suggest, that the global average PIC concentration rather lies between 0.3 – 0.7 wt% (7.5 – 17.6 Tmol(eq)/a). Detrital carbonate delivery by melting icebergs and atmospheric (dry) deposition could possibly represent further sources of alkalinity, but still have to be constrained.

description: The effective evolution of an inhomogeneous cosmological model may be described in terms of spatially averaged variables. We point out that in this context, quite naturally, a measure arises which is identical to a fluid model of the `Kullback-Leibler Relative Information Entropy', expressing the distinguishability of the local inhomogeneous mass density field from its spatial average on arbitrary compact domains. We discuss the time-evolution of `effective information' and explore some implications. We conjecture that the information content of the Universe -- measured by Relative Information Entropy of a cosmological model containing dust matter -- is increasing.

description: Currently, assessment of the potential immunotoxicity of a given agent involves a tiered approach for hazard identification and mechanistic studies, including observational studies, evaluation of immune function, and measurement of susceptibility to infectious and neoplastic diseases. These studies generally use costly low-throughput mammalian models. Zebrafish, however, offer an excellent alternative due to their rapid development, ease of maintenance, and homology to mammalian immune system function and development. Larval zebrafish also are a convenient model to study the innate immune system with no interference from the adaptive immune system. In this study, a respiratory burst assay (RBA) was utilized to measure reactive oxygen species (ROS) production after developmental xenobiotic exposure. Embryos were exposed to non-teratogenic doses of chemicals and at 96 h post-fertilization, the ability to produce ROS was measured. Using the RBA, 12 compounds with varying immune-suppressive properties were screened. Seven compounds neither suppressed nor enhanced the respiratory burst; five reproducibly suppressed global ROS production, but with varying potencies: benzo[a]pyrene, 17β-estradiol, lead acetate, methoxychlor, and phenanthrene. These five compounds have all previously been reported as immunosuppressive in mammalian innate immunity assays. To evaluate whether the suppression of ROS by these compounds was a result of decreased immune cell numbers, flow cytometry with transgenic zebrafish larvae was used to count the numbers of neutrophils and macrophages after chemical exposure. With this assay, benzo[a]pyrene was found to be the only chemical that induced a change in the number of immune cells by increasing macrophage but not neutrophil numbers. Taken together, this work demonstrates the utility of zebrafish larvae as a vertebrate model for identifying compounds that impact innate immune function at non-teratogenic levels and validates measuring ROS production and phagocyte numbers as metrics for monitoring how xenobiotic exposure alters the innate immune system.

description: Over-allocation of irrigation water has led to widespread environmental degradation in the Murray-Darling Basin, prompting discussions of the water efficiency performance of irrigated industries, particularly cotton. There is increasing pressure for irrigators to adopt water efficient practices in line with ecologically sustainable principles, especially with current drought conditions. However, there is great uncertainty surrounding the available measures to improve irrigation efficiency from both ecological and economic standpoints. An integrated biophysical and economic modelling approach is used to determine the optimal allocation of water, irrigation system, source of water, and crop pattern, subject to various environmental and resource targets. Spatially referenced data are used to provide realistic results that are directly applicable to the case study basin in northern New South Wales (NSW). The results can assist in policy design and its implementation to achieve environmental objectives at least cost.

description: Recent statistical studies of observational data unveil relevant correlations between whistler fluctuations and the anisotropic electron populations present in space plasmas, e.g., solar wind and planetary magnetospheres. Locally, whistlers can be excited by two sources of free energy associated with anisotropic electrons, i.e., temperature anisotropies and beaming populations carrying the heat flux. However, these two sources of free energy and the resulting instabilities are usually studied independently preventing a realistic interpretation of their interplay. This paper presents the results of a parametric quasilinear study of the whistler instability cumulatively driven by two counter-drifting electron populations and their anisotropic temperatures. By comparison to individual regimes dominated either by beaming population or by temperature anisotropy, in a transitory regime the instability becomes highly conditioned by the effects of both these two sources of free energy. Cumulative effects stimulate the instability and enhance the resulting fluctuations, which interact with electrons and stimulate their diffusion in velocity space, leading to a faster and deeper relaxation of the beaming velocity associated with a core heating in perpendicular direction and a thermalization of the beaming electrons. In particular, the relaxation of temperature anisotropy to quasi-stable states below the thresholds conditions predicted by linear theory may explain the observations showing the accumulation of these states near the isotropy and equipartition of energy.

description: Standard quantum key distribution protocols are provably secure against eavesdropping attacks, if quantum theory is correct. It is theoretically interesting to know if we need to assume the validity of quantum theory to prove the security of quantum key distribution, or whether its security can be based on other physical principles. The question would also be of practical interest if quantum mechanics were ever to fail in some regime, because a scientifically and technologically advanced eavesdropper could perhaps use post-quantum physics to extract information from quantum communications without necessarily causing the quantum state disturbances on which existing security proofs rely. Here we describe a key distribution scheme provably secure against general attacks by a post-quantum eavesdropper who is limited only by the impossibility of superluminal signalling. The security of the scheme stems from violation of a Bell inequality.

description: Environmental, social, and economic attributes are important for the sustainability of a farming system. Resilience is also important, yet has seldom been directly considered in evaluations of economic sustainability. In economic terms, resilience has to do with the capacity of the farm business to survive in various risks and other shocks. A whole-farm stochastic simulation model over a six-year planning horizon was used to analyse organic and conventional cropping systems using a model of a representative farm in Eastern Norway. The relative sustainability of the systems was examined in terms of terminal financial position.

The restrictions in place due to the COVID epidemic have forced us to develop non-traditional solutions to teach field geology in the last few months, such as virtual field excursions, and entirely new safety and hygiene plans. Many of the solutions we have developed should be made into permanent resources that will increase the accessibility of our courses to students and society. Since ~March 2020, similar resources have been developed collaboratively during regular working meetings by groups such as the US National Association of Geoscience Teachers (NAGT). Conversely sharing of these resources among German tertiary geoscience educators has thus far proceeded on an ad hoc basis. We propose to establish a digital platform, perhaps hosted by the DGGV, for sharing of resources. We would also like to convene regular (monthly?) meetings of interested parties. This presentation time slot will mostly be devoted to discussion and establishment of this concept, but will include description of an example, a one-day virtual Eifel structural geology field excursion run for 2nd and 3rd year students in late May at Universität Mainz. In building this trip we successfully integrated web platforms such as V3Geo.org for 3D outcrop models based on photogrammetry, GoogleEarth, and the app OutcropWizard.de. In future we also plan to interface with StraboSpot.org, and would value suggestions and discussion about other similar platforms or database systems.

description: Social costs and externalities associated with herbicide resistance have not generally been considered by economists. The economics of managing herbicide resistance in weeds has focused on cost-effective responses by growers to the development of resistance at the individual farm and field level. In this paper we argue that the increasing possibility of widespread glyphosate resistance presents a case where social costs associated with glyphosate resistance need to be considered when assessing optimal use of this herbicide resource at the farm level. Social costs associated with the loss of glyphosate efficacy include potential failure of herbicide-resistant crop systems, reduced use of conservation tillage techniques, and a potential greater reliance on herbicides with greater health and environmental risks.

description: Neutron capture data on intermediate mass nuclei are of key importance to nucleosynthesis in the weak component of the slow neutron capture processes, which occurs in massive stars. The ($n,γ$) cross section on $^{70}$Ge, which is mainly produced in the $s$~process, was measured at the neutron time-of-flight facility n_TOF at CERN. Resonance capture kernels were determined up to 40~keV neutron energy, and average cross sections up to 300~keV. Stellar cross sections were calculated from $kT=5$~keV to $kT=100$ keV and are in very good agreement with a previous measurement by Walter and Beer (1985), and recent evaluations. Average cross sections are in agreement with Walter and Beer (1985) over most of the neutron energy range covered, while being systematically smaller for neutron energies above 150~keV. We have calculated isotopic abundances produced in $s$-process environments in a 25 solar mass star for two initial metallicities (below solar, and close to solar). While the low metallicity model reproduces best the solar system germanium isotopic abundances the close to solar model shows a good global match to solar system abundances between mass numbers A=60-80.

description: The present study aimed to evaluate the influence of the IL1B -31C/T polymorphism on gastric inflammatory response and precancerous lesions development – atrophic gastritis (AG) and intestinal metaplasia (IM) – in patients positive for Helicobacter pylori infection with functional dyspepsia (FD). The diagnosis of FD followed the Rome III criteria, and the H. pylori infection was evaluated by urease test and histological examination of gastric biopsies (corpus, antrum, and incisura). The severity of chronic inflammation and inflammatory activity, as well as the presence of precancerous lesions were evaluated accordingly to the updated Sydney System. Genotyping of the IL1B -31C/T polymorphism (rs1143627) was performed by polymerase chain reaction-restriction fragment length polymorphism. A total of 303 patients positive for H. pylori infection with FD were analyzed (81.8% women; mean age of 46.3 ± 12.3 years). No differences were observed in overall genotype frequencies among outcomes evaluated. However, in the dominant -31C allele model (CC+CT vs. TT), the frequency of the TT genotype was significantly higher among patients with moderate/severe chronic inflammation of the antrum than the frequency of the CC+CT genotypes (80.8% vs. 65.2%; OR = 2.25; 95% CI = 1.23-4.24; P = .005). The presence of AG and IM in the gastric mucosa of patients was of 19.5% and 19.1%, respectively. No significant association was observed concerning the frequencies of the genotypes of IL1B -31C/T polymorphism with development of precancerous lesions. In conclusion, our data suggest that genetic variants of the IL1B -31C/T polymorphism play a role in chronic inflammation of the gastric mucosa in H. pylori-infected FD patients.
Orbital Migration and Mass Accretion of Protoplanets in 3D Global Computations with Nested Grids

description: We investigate the evolution of protoplanets with different masses embedded in an accretion disk, via global fully three-dimensional hydrodynamical simulations. We consider a range of planetary masses extending from one and a half Earth's masses up to one Jupiter's mass, and we take into account physically realistic gravitational potentials of forming planets. In order to calculate accurately the gravitational torques exerted by disk material and to investigate the accretion process onto the planet, the flow dynamics has to be thoroughly resolved on long as well as short length scales. We achieve this strict resolution requirement by applying a nested-grid refinement technique which allows to greatly enhance the local resolution. Our results from altogether 51 simulations show that for large planetary masses, approximately above a tenth of the Jupiter's mass, migration rates are relatively constant, as expected in type II migration regime and in good agreement with previous two-dimensional calculations. In a range between seven and fifteen Earth's masses, we find a dependency of the migration speed on the planetary mass that yields time scales considerably longer than those predicted by linear analytical theories. This property may be important in determining the overall orbital evolution of protoplanets. The growth time scale is minimum around twenty Earth-masses, but it rapidly increases for both smaller and larger mass values. Significant differences between two- and three-dimensional calculations are found in particular for objects with masses smaller than ten Earth-masses. We also derive an analytical approximation for the numerically computed mass growth rates.

description: As Australia begins to implement the National Water Initiative, there are lessons to be learned from past experience in rural adjustment and rural assistance schemes. The experience is rich and the messages powerful. Government intervention in the process of adjustment and change can impede, facilitate or expedite adjustment. To maximise the opportunities arising from water reform, several important lessons can be identified. The role of autonomous adjustment processes in generating individual and community wealth is vital. A portfolio of approaches to securing additional water for the environment through the market place are discussed. Opportunities exist to use existing processes to manage environmental impacts, facilitate water trading and target any adjustment assistance.
