DEPLOYABLE ENTRY SYSTEM

description: A general shift to non-destructive controlled re-entry for any kind of launcher element that reaches an orbit after use without dead-end and possibly contaminating disposal in the enviromnent could increase not only economic, but environmental sustainability in the space sector. This paper provides a review on launcher related space debris and deployable concepts are discussed as a cost-effective, integrable technology for a \"design to not demise\". A gap analysis of existing deployable recovery concepts is presented as well as research approaches for the application of rigidly deployable systems for cost efficient orbital stage recovery.
Choline availability modulates human neuroblastoma cell proliferation and alters the methylation of the promoter region of the cyclin-dependent kinase inhibitor 3 gene

description: Choline is an important methyl donor and a component of membrane phospholipids. In this study, we tested the hypothesis that choline availability can modulate cell proliferation and the methylation of genes that regulate cell cycling. In several other model systems, hypomethylation of cytosine bases that are followed by a guanosine (CpG) sites in the promoter region of a gene is associated with increased gene expression. We found that in choline-deficient IMR-32 neuroblastoma cells, the promoter of the cyclin-dependent kinase inhibitor 3 gene (CDKN3) was hypomethylated. This change was associated with increased expression of CDKN3 and increased levels of its gene product, kinase-associated phosphatase (KAP), which inhibits the G1/S transition of the cell cycle by dephosphorylating cyclin-dependent kinases. Choline deficiency also reduced global DNA methylation. The percentage of cells that accumulated bromodeoxyuridine (proportional to cell proliferation) was 1.8 times lower in the choline-deficient cells than in the control cells. Phosphorylated retinoblastoma (p110) levels were 3 times lower in the choline-deficient cells than in control cells. These findings suggest that the mechanism whereby choline deficiency inhibits cell proliferation involves hypomethylation of key genes regulating cell cycling. This may be a mechanism for our previously reported observation that stem cell proliferation in hippocampus neuroepithelium is decreased in choline-deficient rat and mouse fetuses.

description: Irreversible growth of strained epitaxial nanoislands has been studied with the use of the kinetic Monte Carlo (KMC) technique. It has been shown that the strain-inducing size misfit between the substrate and the overlayer produces long range dipole-monopole (d-m) interaction between the mobile adatoms and the islands. To simplify the account of the long range interactions in the KMC simulations, use has been made of a modified square island model. Analytic formula for the interaction between the point surface monopole and the dipole forces has been derived and used to obtain a simple expression for the interaction between the mobile adatom and the rectangular island. The d-m interaction was found to be longer ranged than the conventional dipole-dipole potential. The narrowing of the island size distributions (ISDs) observed in the simulations was shown to be a consequence of a weaker repulsion of adatoms from small islands than from large ones which led to the preferential growth of the former. Furthermore, similarly to the unstrained case, the power-law behavior of the average island size and of the island density on the coverage has been found. In contrast to the unstrained case, the value of the scaling exponent was not universal but strongly dependent on the strength of the long range interactions. Qualitative agreement of the simulation results with some previously unexplained behaviors of experimental ISDs in the growth of semiconductor quantum dots was observed.

competency framework

description: This document describes how the BioExcel Centre of Excellence has worked with its users to agree on the competencies that they require to make the most of HPC for their research. To enrich the competency profile we have, for each competence, defined what an individual will need to know and what skills they need to have to exhibit competence in a specific area, as well as listed what behaviours are suited and unsuited to an individual with that particular competency. We have performed a training needs analysis to gather the competency requirements for BioExcel’s users. These users include: entry-level users (e.g. bench-based molecular life scientists with a very limited computational background, working in both academic and industrial settings); expert users (e.g. structural bioinformaticians/computational chemists, medicinal chemists and others) and computational service providers, including systems administrators, applications experts and others involved in providing high-end computational services and software to biomolecular scientists. An initial workshop was organised to outline the competencies required by these users to make the most of HPC, and the main outcome of the workshop was a matrix of the different target groups against the agreed competencies. A total of 31 competencies have been defined; 5 Generic Competencies, 13 Scientific Competencies; 8 Generic Computing Competencies and 5 Parallel Computing Competencies. We are in the process of mapping these competencies to the learning outcomes of courses already provided by existing training programmes so that we can focus on developing new training that meets currently unmet needs. Though a large number of the competencies have existing courses mapped against them the coverage is often partial or fragmented. At the interim analysis stage (refers to D4.2 versus final analysis in D4.3 due in month 12) 10 out of the 31 competencies are insufficiently covered; based on having less than 5 training resources mapped against the competencies. Taking into account the partial mapping, the number of insufficiently covered competencies increased to 19. Initial plans for the BioExcel Training Programme are presented with mapping against the relevant competencies. The work (task 4.1) underlying this deliverable formally runs until month 12 and the complete results with recommendations for the BioExcel Training Programme will be presented in D4.3 (PM12).

PERFORMANCE

description: The open fan engine, featuring ultra-high propulsive efficiency, is considered one of the most realistic and sustainable option for civil aviation. The preliminary design of such architectures requires a robust and flexible modeling of the propulsor performance. An innovative approach based on induced velocity models combined with aerodynamic polars is proposed for an open fan consisting of a variable pitch propeller rotor and a variable pitch stator. An assessment of the method accuracy is provided, covering propeller map generation, static and reverse performance, and design parametric studies on diameter, aspect ratio and blades count. The proposed method is a good compromise between accuracy and numerical robustness, usable in a cycle performance model, for both design and off-design studies.

description: In a frustrated J_1-J_2 chain with the nearest-neighbor ferromagnetic interaction J_1 and the next-nearest-neighbor antiferromagnetic interaction J_2, novel magnetic states such as a spin-nematic state are theoretically expected. However, they have been rarely examined in experiments because of the difficulty in obtaining suitable model compounds. We show here that the quasi-one-dimensional antiferromagnet NaCuMoO_4(OH), which comprises edge-sharing CuO_2 chains, is a good candidate J_1-J_2 chain antiferromagnet. The exchange interactions are estimated as J_1 = - 51 K and J_2 = 36 K by comparing the magnetic susceptibility, heat capacity, and magnetization data with the data obtained using calculations by the exact diagonalization method. High-field magnetization measurements at 1.3 K show a saturation above 26 T with little evidence of a spin nematic state expected just below the saturation field, which is probably due to smearing effects caused by thermal fluctuations and the polycrystalline nature of the sample.

Phosphorylation of GRK7 by PKA in cone photoreceptor cells is regulated by light

description: The retina specific G protein-coupled receptor kinases, GRK1 and GRK7, have been implicated in the shutoff of the photoresponse and adaptation to changing light conditions via rod and cone opsin phosphorylation. Recently, we have defined sites of phosphorylation by cAMP-dependent protein kinase (PKA) in the amino termini of both GRK1 and GRK7 in vitro. To determine the conditions under which GRK7 is phosphorylated in vivo, we have generated an antibody that recognizes GRK7 phosphorylated on Ser-36, the PKA phosphorylation site. Using this phospho-specific antibody, we have shown that GRK7 is phosphorylated in vivo and is located in the cone inner and outer segments of mammalian, amphibian and fish retinas. Using Xenopus laevis as a model, GRK7 is phosphorylated under dark-adapted conditions, but becomes dephosphorylated when the animals are exposed to light. The conservation of phosphorylation at Ser-36 in GRK7 in these different species (which span a 400 million-year evolutionary period), and its light-dependent regulation, indicate that phosphorylation plays an important role in the function of GRK7. Our work demonstrates for the first time that cAMP can regulate proteins involved in the photoresponse in cones and introduces a novel mode of regulation for the retinal GRKs by PKA.

description: Acute ethanol administration increases potent GABAergic neuroactive steroids, specifically (3α,5α)-3-hydroxypregnan-20-one (3α,5α-THP) and (3α,5α)-3,21-dihydroxypregnan-20-one. In addition, neuroactive steroids contribute to ethanol actions. Chronic ethanol exposure results in tolerance to many effects of ethanol, including ethanol-induced increases in neuroactive steroid levels. To determine the mechanisms of tolerance to ethanol-induced increases in neuroactive steroids, we investigated critical signaling molecules that are required for acute ethanol effects. Male Sprague-Dawley rats were administered ethanol via liquid diet for 2 weeks and steroid levels, adrenocorticotrophic hormone (ACTH) and adrenal steroidogenic acute regulatory (StAR) protein expression were measured. Chronic ethanol exposure elicits tolerance to ethanol-induced elevation of serum ACTH and the steroids pregnenolone and progesterone. Surprisingly, chronic ethanol exposure does not result in tolerance to ethanol-induced increases in adrenal StAR protein. However, ethanol-induced StAR phosphorylation is decreased when compared to acute ethanol administration. A separate group of rats exposed to chronic ethanol diet were subsequently challenged with ethanol (2 g/kg) and exhibited a blunted elevation of serum ACTH and progesterone as well as cerebral cortical and hippocampal 3α,5α-THP. Administration of ACTH with the ethanol challenge restored the elevation of serum ACTH and progesterone as well as cerebral cortical 3α,5α-THP levels to those observed in ethanol-naïve rats. Thus, chronic ethanol exposure disrupts ACTH release, which results in tolerance to ethanol-induced increases in neuroactive steroid levels. Loss of the ethanol-induced increases in neuroactive steroids may contribute to behavioral tolerance to ethanol and influence the progression towards alcoholism.

STRUCTURAL WING DESIGN
TPMS

description: Laminar flow offers significant potential for increasing the energy-efficiency of future transport aircraft. The Cluster of Excellence SE2 A -Sustainable and Energy-Efficient Aviation is developing a new approach for hybrid laminar flow control. The concept aims to maintain laminar flow up to 80 % of the chord length by integrating suction panels at the rear part of the wing, which consist of a thin suction skin and a supporting core structure. This study examines the effects of various suction panel configurations on wing mass and load transfer for an all-electric short-range aircraft. The suction panel material, as well as the thickness and the relative density of the suction panel components are modified in physically meaningful boundaries. Suction panels made from the titanium alloy Ti6Al4V offer the most robust design resulting in a significant increase in wing mass, whereas panels made from Nylonl lCF or PUlO00 do not significantly increase the wing mass. However, the use of these materials raises questions about their robustness under operational conditions. The results of this study demonstrate that the choice of material strongly influences the load path within the wing structure. Ti6Al4V suction panels provide sufficient mechanical properties to significantly contribute to load transfer and buckling stiffness. In contrast, compliant materials such as NylonllCF or PUlO00 are inherently decoupled from load transfer. Unlike the thickness of the suction skin, the relative density of the core structure strongly affects the wrinkling stiffness. However, wrinkling failure did not appear critical for the suction panel configurations analysed in this study.

description: We investigate the origin of the fast recombination dynamics of bound and free excitons in GaN nanowire ensembles by temperature-dependent photoluminescence spectroscopy using both continuous-wave and pulsed excitation. The exciton recombination in the present GaN nanowires is dominated by a nonradiative channel between 10 and 300 K. Furthermore, bound and free excitons in GaN NWs are strongly coupled even at low temperatures resulting in a common lifetime of these states. By solving the rate equations for a coupled two-level system, we show that one cannot, in practice, distinguish whether the nonradiative decay occurs directly via the bound or indirectly via the free state. The nanowire surface and coalescence-induced dislocations appear to be the most obvious candidates for nonradiative defects, and we thus compare the exciton decay times measured for a variety of GaN nanowire ensembles with different surface-to-volume ratio and coalescence degrees. The data are found to exhibit no correlation with either of these parameters, i. e., the dominating nonradiative channel in the GaN nanowires under investigation is neither related to the nanowire surface, nor to coalescence-induced defects for the present samples. Hence, we conclude that nonradiative point defects are the origin of the fast recombination dynamics of excitons in GaN nanowires.

description: The mechanisms of ethanol actions that produce its behavioral sequelae involve the synthesis of potent GABAergic neuroactive steroids, specifically the GABAergic metabolites of progesterone, (3α,5α)-3-hydroxypregnan-20-one (3α,5α-THP), and deoxycorticosterone, (3α,5α)-3,21-dihydroxypregnan-20-one. We investigated the mechanisms that underlie the effect of ethanol on adrenal steroidogenesis. We found that ethanol effects on plasma pregnenolone, progesterone, 3α,5α-THP and cortical 3α,5α-THP are highly correlated, exhibit a threshold of 1.5 g/kg, but show no dose dependence. Ethanol increases plasma adrenocorticotropic hormone (ACTH), adrenal steroidogenic acute regulatory protein (StAR), and adrenal StAR phosphorylation, but does not alter levels of other adrenal cholesterol transporters. The inhibition of ACTH release, de novo adrenal StAR synthesis or cytochrome P450 side chain cleavage activity prevents ethanol-induced increases in GABAergic steroids in plasma and brain. ACTH release and de novo StAR synthesis are independently regulated following ethanol administration and both are necessary, but not sufficient, for ethanol-induced elevation of plasma and brain neuroactive steroids. As GABAergic steroids contribute to ethanol actions and ethanol sensitivity, the mechanisms of this effect of ethanol may be important factors that contribute to the behavioral actions of ethanol and risk for alcohol abuse disorders.

description: Brain norepinephrine and dopamine regulate a variety of critical behaviors such as stress, learning, memory, and drug addiction. Here, we demonstrate differences in the regulation of in vivo neurotransmission for dopamine in the anterior nucleus accumbens (NAc) and norepinephrine in the ventral bed nucleus of the stria terminalis (vBNST) of the anesthetized rat. Release of the two catecholamines was measured simultaneously using fast-scan cyclic voltammetry (FSCV) at two different carbon-fiber microelectrodes, each implanted in the brain region of interest. Simultaneous dopamine and norepinephrine release was evoked by electrical stimulation of a region where the ventral noradrenergic bundle (VNB), the pathway of noradrenergic neurons, courses through the ventral tegmental area/substantia nigra (VTA/SN), the origin of dopaminergic cell bodies. The release and uptake of norepinephrine in the vBNST were both significantly slower than for dopamine in the NAc. Pharmacological manipulations in the same animal demonstrated that the two catecholamines are differently regulated. The combination of a dopamine autoreceptor antagonist and amphetamine significantly increased basal extracellular dopamine whereas a norepinephrine autoreceptor antagonist and amphetamine did not change basal norepinephrine concentration. α-Methyl-p-tyrosine, a tyrosine hydroxylase inhibitor, decreased electrically evoked dopamine release faster than norepinephrine. The dual-microelectrode FSCV technique along with anatomical and pharmacological evidence confirms that dopamine in the NAc and norepinephrine in the vBNST can be monitored selectively and simultaneously in the same animal. The high temporal and spatial resolution of the technique enabled us to examine differences in the dynamics of extracellular norepinephrine and dopamine concurrently in two different limbic structures.

description: Ethanol exposure produces alterations in GABAA receptor function and expression associated with CNS hyperexcitability, but the mechanisms of these effects are unknown. Ethanol is known to increase both GABAA receptor α4 subunits and protein kinase C (PKC) isozymes in vivo and in vitro. Here, we investigated ethanol regulation of GABAA receptor α4 subunit expression in cultured cortical neurons to delineate the role of protein kinase C. Cultured neurons were prepared from rat pups on post-natal day 0-1 and tested after 18 days. GABAA receptor α4 subunit surface expression was assessed using P2 fractionation and surface biotinylation following ethanol exposure for 4 hrs. Miniature inhibitory postsynaptic currents (mIPSCs) were measured using whole cell patch clamp recordings. Ethanol increased GABAA receptor α4 subunit expression in both the P2 and biotinylated fractions, while reducing the decay time constant in mIPSCs, with no effect on γ2 or δ subunits. PKC activation mimicked ethanol effects, while the PKC inhibitor calphostin C prevented ethanol-induced increases in GABAA receptor α4 subunit expression. PKCγ siRNA knockdown prevented ethanol-induced increases in GABAA receptor α4 subunit expression, but inhibition of the PKCβ isoform with PKCβ pseudosubstrate had no effect. We conclude that PKCγ regulates ethanol-induced alterations in α4-containing GABAA receptors.

description: Suppose that $Q$ is a connected quiver without oriented cycles and $σ$ is an automorphism of $Q$. Let $k$ be an algebraically closed field whose characteristic does not divide the order of the cyclic group $\langleσ\rangle$. The aim of this paper is to investigate the relationship between indecomposable $kQ$-modules and indecomposable $kQ\#k\langleσ\rangle$-modules. It has been shown by Hubery that any $kQ\#k\langleσ\rangle$-module is an isomorphically invariant $kQ$-module, i.e., ii-module (in this paper, we call it $\langleσ\rangle$-equivalent $kQ$-module), and conversely any $\langleσ\rangle$-equivalent $kQ$-module induces a $kQ\#k\langleσ\rangle$-module. In this paper, the authors prove that a $kQ\#k\langleσ\rangle$-module is indecomposable if and only if it is an indecomposable $\langleσ\rangle$-equivalent $kQ$-module. Namely, a method is given in order to induce all indecomposable $kQ\#k\langleσ\rangle$-modules from all indecomposable $\langleσ\rangle$-equivalent $kQ$-modules. The number of non-isomorphic indecomposable $kQ\#k\langleσ\rangle$-modules induced from the same indecomposable $\langleσ\rangle$-equivalent $kQ$-module is given. In particular, the authors give the relationship between indecomposable $kQ\#k\langleσ\rangle$-modules and indecomposable $kQ$-modules in the cases of indecomposable simple, projective and injective modules.

Taxonomic Databases

description: The thesis investigates the application of concepts and techniques of data quality in taxonomic databases to enhance the quality of information services and systems in taxonomy. Taxonomic data are arranged and introduced in Taxonomic Data Domains in order to establish a standard and a working framework to support the proposed Taxonomic Data Quality Dimensions, as a specialised application of conventional Data Quality Dimensions in the Taxonomic Data Quality Domains. The thesis presents a discussion about improving data quality in taxonomic databases, considering conventional Data Cleansing techniques and applying generic data content error patterns to taxonomic data. Techniques of taxonomic error detection are explored, with special attention to scientific name spelling errors. The spelling error problem is scrutinized through spelling error detecting techniques and algorithms. Spelling error detection algorithms are described and analysed. In order to evaluate the applicability and efficiency of different spelling error detection algorithms, a suite of experimental spelling error detection tools was developed and a set of experiments was performed, using a sample of five different taxonomic databases. The results of the experiments are analysed from the algorithm and from the database point of view. Database quality assessment procedures and metrics are discussed in the context of taxonomic databases and the previously introduced concepts of Taxonomic Data Domains and Taxonomic Data Quality Dimensions. Four questions related to Taxonomic Database Quality are discussed, followed by conclusions and recommendations involving information system design and implementation and the processes involved in taxonomic data management and information flow.

description: In order to successfully return to the Moon and establish a sustainable human presence, as well as pave the way for future Martian exploration, it is we must undertake new, targeted development efforts. With the successful launch of the Artemis I mission, flyby of the Moon and the safe return of the Crew Module, research laboratories are motivated to identify mission risks and to benefit from the significant progress in materials science which could be applied to these questions. This paper reviews challenges linked to different functional surfaces; those exposed to a harsh external environment and those making up the interior of space stations, illustrating them with selected ESA-funded projects. The issue of biofilm formation in the confined environment of the I SS and in the interior of spacesuits will be amplified over longer time-periods by limited access to resources, decreased immune response of the crew and increased pathogenicity of mutating microbes. There are efforts towards achieving robust low-cytotoxicity surface treatments, especially for wet applications ( e.g., water pipes), which do not contain heavy metals as it has been shown that these metals tend to leak into water condensate The project presented here successfully produced efficient coatings based on natural antimicrobial agents and active nanoparticles. Moreover, in another project, photoactive surface treatments with titanium compounds also resulted in effective antimicrobial barriers with long-term stability, which could be additionally helpful in bioburden control. The interaction with lunar dust, known for its abrasive nature and electrostatic charge, poses a significant challenge for surfaces directly exposed to the lunar environment, as observed during the Apollo missions. This is applicable to EVA suit external layers as well as thermal control surfaces, mechanisms and seals. Technology development efforts aiming at characterization of the impact of lunar dust on various materials, as well as mitigation strategies for the dust, will be summarized. In the framework of the PexTex (Planetary Exploration Textile) project a selection of state-of-the-art textiles for external surfaces of EVA suit for lunar exploration was undertaken [2). An extensive series of material tests, including nuclear accelerator-based radiation tests, abrasion tests on a Double Head Abraser and in a tumbler chamber were performed using representative lunar regolith simulants.
