description:
Most high-grade metamorphic gneiss units in Germany exhibit a strong late-Variscan thermal imprint recorded by the presence of migmatites and granitic intrusions.

A nuclear waste repository in this setting is challenging because the amalgamation of various gneisses and magmatic rocks must be predicted and assessed to a search depth of 1500 m. Understanding the 3D-architecture of such basement units relies on better exposed regions than found in Germany. In this contribution, we use selected field areas to show the difficulty to predict the variability of high-grade metamorphic rock types at depth.

The Argentera Massif in the western Alps represents an ideal field analogue as it displays a variety of para- and orthogneisses and their equivalent migmatites along continuous surface outcrops. Detailed field observations from this area help to constrain the structural and lithological anisotropy of a typical Moldanubian crustal segment.

Except for the occurrence of large amphibolite lenses, gneisses and migmatites exhibit textural gradients at various scales rather than distinct lithological boundaries. Sharp boundaries on the other hand result from cross-cutting shear-zones that developed under retrograde greenshist facies conditions and discordant intrusions.

Whereas the overall 3D-geometry and anisotropy of the gneiss terrane may be described with the help of 3D models it is generally not possible to predict the spatial distribution of lithotypes and dominant textures for a given rock volume.

This contribution indicates why foliated gneisses and migmatites are less suitable as host rocks for a high-level radioactive waste repository compared with late granitoid intrusions that are more homogeneous.

description:
The publication and accessibility of geological data is one of the main tasks of geological surveys. Provided data helps to understand the local geology, facilitates exploration of natural resources and thus benefits state services, businesses, and the public alike. The State Geological Survey of Saxony-Anhalt (LAGB) uses its database from decades of geological exploration to provide information of the subsurface geology. Past interpretations existed but provided only simple presentations of the three-dimensional space. More recently, huge datasets were used for the development of largely enhanced 3D models. So far, regional 3D models have been prepared for the deep subsurface comprising the Altmark region in the north, the Subhercynian Basin in the middle, and the South-Eastern Harz Foreland in the south of Saxony-Anhalt. These models are based on existing maps from subsurface exploration, seismic profiles, and borehole information. ArcGIS and SKUA-GOCAD were used as data management and modelling tools. Some challenges consist of low data density in some regions, contradictory or incorrect source data, as well as in achieving a coherent 3D model by smooth integration of modelled layers from different authors. The resulting three-dimensional geological models of Saxony-Anhalt illustrate the structural setting and the geology of the Earth's subsurface and will become subsequently filled with further lithological and petrophysical parameters. To publish the models for a broader audience, we use the GST (Geosciences in Space and Time) framework. This toolkit eventually enables the creation of customized sections, virtual borehole profiles, and the export of parts of the models.

description:
Shell carbonates of marine molluscs are a widely used archive for paleo-environmental reconstructions. However, their use for temperature reconstructions may be impeded by species-specific vital effects and/or a lack of knowledge of the chemical and isotopic composition of paleo-seawater. Clumped isotope (∆47) thermometry of marine carbonates enables temperature reconstructions independent of seawater composition provided the carbonate formed in thermodynamic equilibrium. Dual clumped isotope thermometry, i.e. simultaneous analysis of ∆48 alongside ∆47, offers the opportunity to determine if a carbonate formed in isotopic equilibrium and to account for kinetic effects taking place prior to and/or during precipitation. Here, we present dual clumped isotope data for several modern mollusc specimens (including bivalves and gastropods) with average growth temperatures ranging from 5-27°C. We find that most specimens analysed in this study exhibit dual clumped isotope compositions which are indistinguishable from equilibrium. Moreover, their ∆47-derived temperatures agree within errors with their growth temperatures. We interpret the apparent equilibrium calcification of mollusc shell carbonates to be a possible consequence of a relatively low pH at the site of calcification. The absence of any resolvable kinetic isotope effects makes molluscs a reliable archive for highly precise (95CI of <2.2°C) temperature reconstructions via ∆47-analysis. Based on previous ∆47 investigations of molluscs grown at known seawater oxygen isotope compositions (δ18OSW), we also determine the temperature dependencies of the oxygen isotope fractionation between seawater and molluscan aragonite/calcite.

∆47 and δ18O values of fossil molluscs may be used in conjunction with these calibrations to reconstruct both - seawater-δ18O and temperature.
Hyperglycemia Presenting as Left Middle Cerebral Artery Stroke: a Case Report

description: Background and Purpose—Hyperglycemia is an important diagnostic differential and has been reported to cause focal neurological deficits masquerading as stroke. Discussion of hyperglycemia as a stroke mimic has been sparse in the era of diffusion weighted imaging, but remains an important mimic. Case Summary—A 67 year-old right-handed woman with presented with lethargy, global aphasia, left eye deviation and right hemiparesis. She received IV t-PA for left MCA syndrome and transferred for possible intervention. Initial labs showed a glucose 825mg/dL. MRI/MRA brain was negative for acute stroke with patent vessels, but abnormalities on MRperfusion. The patient was admitted and treated with medical resuscitation including IV fluids and an insulin drip. After normoglycemia was achieved the patient's neurological deficits resolved. EEG on day one of hospitalization showed left hemispheric slowing that subsequently normalized on continuous recording. Conclusion—We report a case of hyperglycemia clinically mimicking a left MCA syndrome reversed with medical management possibly explained by metabolic demand-blood flow coupling of inactive tissue rather than hypoperfused tissue at risk of infarction

description: Experimental validation of a quasi-one-dimensional control volume ejector-ramjet solver was performed at various subsonic inlet flow conditions corresponding to high-entrainment ratios. An ejector apparatus was designed to replicate the intake of an ejector-ramjet currently under development. The apparatus was then connected to a vacuum tank with which the desired inlet conditions were achieved by drawing down the tank, and restricting flow with various-sized orifice plates. The experiments conducted consisted of varying the cross-sectional flow area of the mixing tube, and testing with multiple primary jet mass flow rates to attain a wide range of data to validate the 1D-ERAM solver against. Two groups of simulations were performed with the 1D-ERAM, one where the calculations used a fully developed turbulent flow friction factor, and the other where the friction factor calculations accounted for flow development from the entrance of the mixing tube. From the experimental data ejector performance parameters of entrainment and compression ratios were calculated, and then compared against the predictions made by the 1D-ERAM solver.

description: Background:: In the 2-year CARE-MS I and II trials, alemtuzumab 12 mg administered on 5 consecutive days at core study baseline and on 3 consecutive days 12 months later significantly improved outcomes versus subcutaneous interferon beta-1a (SC IFNB-1a) in relapsing–remitting multiple sclerosis patients. Here, we present the final 6-year CARE-MS extension trial results (CAMMS03409), and compare outcomes over 6 years in patients randomized to both treatment groups at core study baseline. Methods:: Over a 4-year extension, alemtuzumab patients (alemtuzumab-only) received as-needed additional alemtuzumab (⩾12 months apart) for disease activity after course 2. SC IFNB-1a patients who entered the extension discontinued SC IFNB-1a and received 2 alemtuzumab 12 mg courses (IFN–alemtuzumab), followed by additional, as-needed, alemtuzumab. Results:: Through year 6, 63% of CARE-MS I and 50% of CARE-MS II alemtuzumab-only patients received neither additional alemtuzumab nor other disease-modifying therapy, with lasting suppression of disease activity, improved disability, and slowing of brain volume loss (BVL). In CARE-MS I patients (treatment-naive; less disability; shorter disease duration), disease activity and BVL were significantly reduced in IFN–alemtuzumab patients, similar to alemtuzumab-only patients at year 6. Among CARE-MS II patients (inadequate response to prior treatment; more disability; longer disease duration), alemtuzumab significantly improved clinical and magnetic resonance imaging outcomes, including BVL, in IFN–alemtuzumab patients; however, disability outcomes were less favorable versus alemtuzumab-only patients. Safety profiles, including infections and autoimmunities, following alemtuzumab were similar between treatment groups. Conclusion:: This study demonstrates the high efficacy of alemtuzumab over 6 years, with a similar safety profile between treatment groups.

description:
Any keen observer has noticed that valleys show a large variability in their shapes, explained by the incision and widening processes. However, valley widening processes and rate are still poorly documented while valley evolution has a key role in geomorphological processes (contribution to the formation of abrasion terraces and establishment of ecosystems) and global geochemical cycles (increase of carbon storage in wide valley and buffering sediment fluxes transported to the oceans). Given these issues, it is becoming truly necessary to better understand valley widening rate and its controls.

For that, we focused on several river valleys (in the Arequipa Province, Peru, and in the plateau of Valensole, France) and we have used and further developed the approach tested in northern Chile by Zavala et al. (2021). We collected samples from valley flanks to measure the millennial erosion rates, by using in-situ produced Beryllium-10 and Aluminium-26, and analysed 10-Be and 26-Al concentrations to estimate the local valley flank erosion rate.

We also extracted different factors that may control widening rate (valley width, slope of flanks and valley floors, incision and drainage area, etc) in order to compare these factors to 10-Be and 26-Al concentrations. Our preliminary results show comparable 10-Be concentrations along a single stretch of valley, except for several outliers, for different valleys in the Andes and France, indicating some robustness in the sampling method. These results are promising and will provide new answers, by integrating more metadata, about what controls the widening rate of valleys and how.

description: As an immune-inspired algorithm, the Dendritic Cell Algorithm (DCA), produces promising performances in the field of anomaly detection. This paper presents the application of the DCA to a standard data set, the KDD 99 data set. The results of different implementation versions of the DXA, including the antigen multiplier and moving time windows are reported. The real-valued Negative Selection Algorithm (NSA) using constant-sized detectors and the C4.5 decision tree algorithm are used, to conduct a baseline comparison. The results suggest that the DCA is applicable to KDD 99 data set, and the antigen multiplier and moving time windows have the same effect on the DCA for this particular data set. The real-valued NSA with constant-sized detectors is not applicable to the data set, and the C4.5 decision tree algorithm provides a benchmark of the classification performance for this data set.

description:
Even if the knowledge of Triassic tetrapod communities and their role in terrestrial ecosystems has increased in the recent decades, the paucity of fossil sites from this time interval has hindered their complete understanding. In order to shed light on how the Triassic tetrapod communities were, evolved and interacted in their habitats, we are carrying out a series of multidisciplinary studies on the Ladinian Lower Keuper successions (Erfurt Formation) of southwestern Germany. These facies were deposited in a vast epicontinental platform of the Central European Basin, influenced by the Tethys Sea. The Lower Keuper in the study areas consists of a 20–25 m thick succession of alternating siliciclastic and carbonate deposits, mostly grey to green mudstones and marlstones, and yellowish to blueish dolostones, as well as occasional sandstones. The succession is divided in more discrete units, some of which forming exceptional fossillagerstätten with thousands of tetrapod remains recovered and tens of new tetrapod taxa (including basal members of different lineages) described to date. Sedimentological, taphonomic and palaeoecological data show that ecosystems were complex, with several levels within the trophic chain and including at least two top predators: a pseudosuchian archosaur and a giant capitosaur temnospondyl. Of note, fish diversity is particularly high, with at least 14 taxa so far known. The occurrence of the same vertebrate taxa, but in different proportions and from different ontogenetic stages throughout the stratigraphic succession and in different localities corresponding to slightly different environmental settings, indicates stability of the ecosystems.

description:
The end of the Late Palaeozoic Ice Age (LPIA) was characterized by the development of widespread peat-forming mires across Gondwana concurrently with the evolution of the Glossopteris­-flora. The Aramac Coal Measures in the Galilee Basin of Australia represent some of the early phase of humic peat formation following the deglaciation in an ameliorating climate. This work aims to examine two boreholes using a multidisciplinary approach involving palynology, coal petrology, carbon isotope geochemistry and biomarkers to reconstruct the climate, environment and floras of this post-glacial period.

Palynostratigraphy suggests a late Artinskian to early Kungurian age for the Aramac Coal Measures separated from the overlying JK seams by an unconformity. Small-scale sedimentary dykes and cryostructured palaeosols suggest the peats would have formed under permafrost conditions. Palynological assemblages display a typical mix of early Permian elements and remnants of the Carboniferous floras with striate bisaccate pollen representing glossopterids, monosaccate pollen representing cordaitaleans, and spores representing herbaceous ferns, lycopsids and horsetails. Maceral analysis of the coals show high inertinite values, which, along with pristane/phytane ratios indicate an oxidative environment in which the peats were influenced by fire and/or fungi and bacteria. Stable carbon isotope values are typical for terrestrial environments (-22‰ to -26‰) but show an apparent cyclicity that may be related to climatic fluctuations following the end of the glaciation. This indicates the rise of the Glossopteris-flora was a gradual process which may have been influenced by warm and cool climatic phases well into the Permian.

description: Context : AKARI is the first Japanese astronomical satellite dedicated to infrar ed astronomy. One of the main purposes of AKARI is the all-sky survey performed with six infrared bands between 9 and 200um during the period from 2006 May 6 to 2007 August 28. In this paper, we present the mid-infrared part (9um and 18um b ands) of the survey carried out with one of the on-board instruments, the Infrar ed Camera (IRC). Aims : We present unprecedented observational results of the 9 and 18um AKARI al l-sky survey and detail the operation and data processing leading to the point s ource detection and measurements. Methods : The raw data are processed to produce small images for every scan and point sources candidates, above the 5-sigma noise level per single scan, are der ived. The celestial coordinates and fluxes of the events are determined statisti cally and the reliability of their detections is secured through multiple detect ions of the same source within milli-seconds, hours, and months from each other. Results : The sky coverage is more than 90% for both bands. A total of 877,091 s ources (851,189 for 9um, 195,893 for 18um) are confirmed and included in the cur rent release of the point source catalogue. The detection limit for point source s is 50mJy and 90mJy for the 9um and 18um bands, respectively. The position accu racy is estimated to be better than 2". Uncertainties in the in-flight absolute flux calibration are estimated to be 3% for the 9um band and 4% for the 18um ban d. The coordinates and fluxes of detected sources in this survey are also compar ed with those of the IRAS survey and found to be statistically consistent.

description: Modeling of molecular emission from interstellar clouds requires the calculation of rates for excitation by collisions with the most abundant species. The present paper focuses on the calculation of rate coefficients for rotational excitation of the HCN and HNC molecules in their ground vibrational state in collision with He. The calculations are based on new two-dimensional potential energy surfaces obtained from highly correlated \textit{ab initio} calculations. Calculations of pure rotational (de)excitation cross sections of HCN and HNC by He were performed using the essentially exact close-coupling method. Cross sections for transitions among the 8 first rotational levels of HCN and HNC were calculated for kinetic energies up to 1000 cm$^{-1}$. These cross sections were used to determine collisional rate constants for temperatures ranging from 5 K to 100 K. A propensity for even $Δj$ transitions is observed in the case of HCN--He collisions whereas a propensity for odd $Δj$ transitions is observed in the case of HNC--He collisions. The consequences for astrophysical models are evaluated and it is shown that the use of HCN rate coefficients to interpret HNC observations can lead to significant inaccuracies in the determination of the HNC abundance, in particular in cold dark clouds for which the new HNC rates show that the $j=1-0$ line of this species will be more easily excited by collisions than HCN. An important result of the new HNC-He rates is that the HNC/HCN abundance ratio derived from observations in cold clouds has to be revised from $>$1 to $\simeq$1, in good agreement with detailed chemical models available in the literature.

description: Background: A comprehensive approach to drug repositioning will be required to overcome translational hurdles and identify more neuroprotective drugs. Results & methods: Gene Set Enrichment Analysis was applied to identify related pathways and enriched genes. Candidate genes were optimized using ToppGene, ToppGenet and pBRIT. From the perspective of the local structures, gene–domain–substructure–drug relationships were constructed. Using the MCODE algorithm and K-means clustering, 31 functional subnetworks were obtained, and 252 drugs with proposed neuroprotective function were identified. Using computational analysis, 72 substructures with different scores were found to correspond to neuroprotective functions. The protective effects of benidipine and barnidipine were confirmed in vitro. Conclusion: The authors' research has great potential to discover more neuroprotective drugs and obtain more information regarding mechanisms of action and functional substructures.

description:
Understanding collision zones and their geodynamic processes is crucial for comprehending plate tectonics, mountain building, and seismic activities. This study employs the software MDOODZ for numerical thermo-mechanical modelling, specifically designed to simulate the mechanical behaviour and thermal evolution of rocks in 2D complex geological settings.

Focusing on a collision zone, we investigate the influence of anisotropy on geodynamic processes. Anisotropy, resulting from preferred orientations of minerals or rock structures, plays a significant role in the deformation behaviour and mechanical response of stressed rocks. By incorporating anisotropy effects using the director vector and transformation matrix approaches proposed by Mühlhaus (2002) and Fletcher (2005), respectively, we explore its impact on the overall geodynamic evolution of the collision zone.

Our 2D thermo-mechanical numerical model captures the essential dynamics of the collision zone, considering the coupling of mechanical and thermal processes, including rock rheology, heat transfer, and their interactions. Accounting for anisotropic properties enables us to investigate the implications of various orientations and strengths of anisotropy on geodynamic processes within the collision zone.

Our findings contribute to understanding collision zone dynamics, highlighting the significance of anisotropy effects in shaping geological processes. The utilisation of MDOODZ, in conjunction with anisotropy incorporation, facilitates exploring the intricate interplay between anisotropy and thermo-mechanical interactions in collision zones.

description: The distribution of cold gas in dark matter haloes is driven by key processes in galaxy formation: gas cooling, galaxy mergers, star formation and reheating of gas by supernovae. We compare the predictions of four different galaxy formation models for the spatial distribution of cold gas. We find that satellite galaxies make little contribution to the abundance or clustering strength of cold gas selected samples, and are far less important than they are in optically selected samples. The halo occupation distribution function of present-day central galaxies with cold gas mass > 10^9 h^-1 Msun is peaked around a halo mass of ~ 10^11 h^-1 Msun, a scale that is set by the AGN suppression of gas cooling. The model predictions for the projected correlation function are in good agreement with measurements from the HI Parkes All-Sky Survey. We compare the effective volume of possible surveys with the Square Kilometre Array with those expected for a redshift survey in the near-infrared. Future redshift surveys using neutral hydrogen emission will be competitive with the most ambitious spectroscopic surveys planned in the near-infrared.

The Specialized Information Service for Geosciences FID GEO has adopted this holistic view and considers the areas of text and data publications as two complementary components of Open Science.

Since 2016, FID GEO is offering information and publication services for the geoscientific community and is increasingly acknowledged as a competence center for the transformation of the publication culture in the geosciences. FID GEO’s services focus on electronic publishing of texts and research data, as well as digitization through the participating repositories GEO-LEOe-docs, hosted at the Göttingen State and University library (SUB), and GFZ Data Services, hosted at the GFZ German Research Centre for Geosciences, but also a comprehensive consulting portfolio.

FID GEO’s services were developed with the active participation of the geoscience community. The website, social media accounts and our newsletter are tools for actively connecting with the community. Informations on practical aspects of Open Science practices are regularly published in the journal “GMIT – Geowissenschaftliche Mitteilungen”, on the website and partner websites (e.g. forschungsdaten.info). Workshops and talks are successful tools to enable discussions, to address questions or uncertainties directly and to provide the appropriate framework to address specific requirements of individual research groups. FID GEO collaborates with strategic (inter)national initiatives (like NFDI4Earth), with several German Geosciences societies and other library-related projects to ensure the ongoing successful shift towards Open Science practices.

description: The Dirac-Morse problem are investigated within the framework of an approximation to the term proportional to $1/r^2$ in the view of the position-dependent mass formalism. The energy eigenvalues and corresponding wave functions are obtained by using the parametric generalization of the Nikiforov-Uvarov method for any $κ$-value. It is also studied the approximate energy eigenvalues, and corresponding wave functions in the case of the constant-mass for pseudospin, and spin cases, respectively.

description: We have analyzed the beam spin asymmetry and the longitudinally polarized target spin asymmetry of the Deep Virtual Compton Scattering process, recently measured by the Jefferson Lab CLAS collaboration. Our aim is to extract information about the Generalized Parton Distributions of the proton. By fitting these data, in a largely model-independent procedure, we are able to extract numerical values for the two Compton Form Factors $H_{Im}$ and $\tilde{H}_{Im}$ with uncertainties, in average, of the order of 30%.

description: This article is devoted to the study of the role of the CICA as one of the priority directions of the foreign policy of the Republic of Kazakhstan. The paper examines “confidence-building measures” and their practical implementation in the activities of the CICA, studies the main forms of interaction between Asian countries in the field of security within the framework of the conference, identifies existing problems and offers practical recommendations to increase the effectiveness of the further development of the CICA. The idea of convening the CICA belongs to the President of the Republic of Kazakhstan N.A. Nazarbayev and for the first time this initiative was announced at the 47th session of the UN in 1992. It is known that there is an Organization for Security and Cooperation (OSCE) on the European continent, it became necessary to create a similar organization in the Asian region. In this regard, N. Nazarbayev's proposal is a necessary response to global challenges. In the context of the globalization of the modern world, the increasing interdependence of the states of the world, the search for a joint solution to current problems is acquiring great importance. The main goal of the CICA is to strive to create an effective and acceptable structure for ensuring peace and security in Asia. The member states, reaffirming their adherence to the UN Charter, believe that peace and security in Asia can be achieved through dialogue and cooperation, leading to a common inseparable area of security in Asia, where states will coexist peacefully and their peoples live in an atmosphere of peace. freedom and prosperity. Now CICA has a great potential in ensuring security on the Asian continent. For the Republic of Kazakhstan, the development of this project is the most significant since it was initiated and continues to present ideas for the modernization of the CICA activities. Also, the article pays special attention to the analysis of the priorities of Kazakhstan as chairman of the CICA in 2020-2022, in particular the issue of further institutionalization of the meeting, which will expand cooperation between the member states, as well as increase the status of the Forum in the international arena.
title: Problems with geothermal probes in evaporite deposits in Saxony-Anhalt

description:
Near-surface geothermal energy as a key technology for the sustainable provision of heating and cooling is increasingly coming into focus as renewable energy and alternative to fossil fuels. In Saxony-Anhalt with an estimated 6,000 geothermal systems operational, several hundreds are being installed annually, incresasingly also in public and commercial buildings.

Areas, where water-soluble rocks carry the risk of karstification and sinkhole occurrence, are clustered in places of the Zechstein outcrop on the Harz Mountain rim, on the contours of the Halle Permo-Carboniferous complex and the Flechtinger Höhenzug. Near-surface Upper Buntsandstein, Middle Muschelkalk and Gipskeuper karstable rocks occur in the Weferlingen-Schönebecker Scholle, in the Hakel, Huy, Fallstein, the Oschersleben-Egelner salt axis, and in the Subherzyn.

Karst areas often contain particularly concrete-aggressive waters, so that special measures must be taken to protect geothermal probes. In addition, in the often cavernous or fissured rock, mud losses are to be expected, or the proper backfilling of the borehole is problematic. Further aspects can be the reduced thermal conductivity.

There is a risk of volume increase due to the transformation of anhydrite into gypsum after contact with water, which can lead to uplift of the terrain above evaporite lithologies. Building ground hazards can occur in the area of salt mining and near-surface salt deposits.

Permitting practice shows that for site-specific projects in the karst areas of Saxony-Anhalt sensu lato, heat recovery from the ground via geothermal collectors is recommended in order to avoid scoring, dissolution and hydration of the rock at risk of subrosion.

description:
The Pustertal-Gailtal Line (PGL) belongs to the dextrally transpressive Periadriatic Fault system and forms the border between Southern and Eastern Alps. Although part of the ongoing convergence between Adria and Europe appears to be accommodated by this fault system, it reveals little instrumental and historical seismicity. In our study, we attempted to find evidence for past seismic activity along the PGL by investigating pseudotachylite occurrences.

We investigated an area of c. 19 km2 to either sides of the PGL around Maria Luggau (Austria). We identified cataclasites and fault gouges along the fault core zone, from which we investigated only the cohesive rocks. Cataclastic, foliated Oligocene granitoids as well as garnet-mica schists of the Austroalpine basement are crosscut by cm- to dm-scale veins containing black fault rocks, which were sampled for further analyses.

Polarisation microscopy reveals that the vein-forming black fault rocks are often optically isotropic, testifying to their origin as quenched melts. Sharp margins of mm- to cm-sized injection veins against the surrounding host rock, well-rounded quartz and feldspar clasts, the absence of hydrous minerals in the matrix, as well as spherulites are further hints at a seismogenic origin of the studied fabrics. Some of the optically isotropic veins are internally foliated; their in-situ µ-XRF analysis of major element concentrations revealed chemical composition variations in the foliation. Even if this foliation might suggest overprinting by aseismic creep, our observations indicate a seismogenic origin of the studied fabrics as pseudotachylites.

title: Computational Diagnostics of End-of-Injection Spray Combustion

description: While low-temperature combustion (LTC) strategies have been found to mitigate nitrogen oxides and particulate matter emissions in diesel engines, studies have also associated LTC with an increase in unburnt hydrocarbons. In recent studies on diesel sprays after end-of-injection (AEOI), combustion recession is identified as a phenomenon where at near nozzle regions, high-temperature ignition (HTI) occurs, thereby consuming the unburnt hydrocarbons AEOI. Current literature has suggested that combustion recession is controlled by auto-ignition. However, high-fidelity simulations and detailed analysis of such a mechanism are missing. In this work, comprehensive Large Eddy Simulations of a reacting spray at relevant diesel spray LTC conditions are performed, where the initial results are validated using experimental data, and the detailed analysis of combustion recession concerning flame morphology and propagation modes is included. In particular, this study demonstrated for the first time that while combustion recession is mainly auto-ignition dominated (consistent with the literature), a cool flame was found to deflagrate towards the richer regions of the mixture, promoting mixing and increasing the mixture temperature. This leads to HTI kernels, which then grow and develop as deflagrative waves, therefore sustaining the combustion recession process. This finding highlights the importance of considering these two modes in end-of-injection combustion in the development of turbulence-chemistry interaction models. The study also detailed the extinction mechanism of combustion: the entrainment wave will overlean the near-nozzle mixtures, rendering it unable to support HTI, which leads to the extinction of the upstream flame AEOI in lower reactivity mixtures. Combustion recession is also observed to be contingent on the chemical and diffusion processes, even at low scalar dissipation rates. Finally, a new criterion for combustion recession based on the Chemical Explosive Mode Analysis is proposed and corroborated with a previous combustion recession metric to quantify the extent of HTI at near-nozzle mixtures AEOI. The newly developed metric combined with an earlier experimentally-based metric can provide simple but valuable measurements of the degree and propensity of the upstream flame AEOI.

description: We report a systematic study on the effect of sintering temperature on the structural and superconducting properties of nominal SmO0.8F0.2FeAs fabricated by simple one-step solid state reaction method. A detailed correlation between the sintering temperature, structure, onset transition temperature (Tc) and critical current density (Jc) has been found in all samples of each batch. Most importantly, samples sintered at a low temperature clearly shows high Tc, for example the Tc of the samples sintered at 850C is even above 53 K, and the samples prepared at 1000C display the highest Tc of 56.1 K reported so far. Furthermore, the samples sintered at 1000C also show the highest RRR and the lowest resistivity(57K), indicating the low impurity scattering and enhanced carrier density. However, the maximum Jc of 10510 A/cm^2 at 5 K in self field was achieved in the samples sintered at 1100oC. The dependence of Tc on a-axis lattice constant indicates that the sintering temperature has strong influence on the effective substitution level of F for O. This result suggests that annealing at a temperature of ~1000C seems much better for obtaining high quality 1111 phase oxypnictides, compared to commonly used temperatures of around 1200C.
