description: This work presents a large consistent study of molybdenum (Mo) and ruthenium (Ru) abundances in the Milky Way. These two elements are important nucleosynthetic diagnostics. In our sample of 71 Galactic metal-poor field stars, we detect Ru and/or Mo in 51 of these (59 including upper limits). The sample consists of high-resolution, high signal-to-noise spectra covering both dwarfs and giants from [Fe/H]=-0.63 down to -3.16. Thus we provide information on the behaviour of Mo I and Ru I at higher and lower metallicity than is currently known. We find a wide spread in the Mo and Ru abundances, which is typical of heavy elements. This indicates that several formation processes, in addition to high entropy winds, can be responsible for the formation of Mo and Ru. The formation processes are traced by comparing Mo and Ru to elements (Sr, Zr, Pd, Ag, Ba, and Eu) with known formation processes. We find contributions from different formation channels, namely p-, slow (s-), and rapid (r-) neutron-capture processes. Molybdenum is a highly convolved element that receives contributions from several processes, whereas Ru is mainly formed by the weak r-process as is silver. We also compare our absolute elemental stellar abundances to relative isotopic abundances of presolar grains extracted from meteorites. Their isotopic abundances can be directly linked to the formation process (e.g. r-only isotopes) providing a unique comparison between observationally derived abundances and the nuclear formation process. The comparison to abundances in presolar grains shows that the r-/s-process ratios from the presolar grains match the total elemental chemical composition derived from metal-poor halo stars with [Fe/H]~ -1.5 to -1.1 dex. This indicates that both grains and stars around and above [Fe/H]=-1.5 are equally (well) mixed and therefore do not support a heterogeneous presolar nebula... Abridged.

description: The application of strain to quantum materials is a powerful technique for tuning electronic correla-tions and the balance between interaction parameters by favoring specific electronic phases over al-most degenerate competing orders via breaking underlying crystal symmetries. For example, it can promote a long-range charge-ordered state over high-temperature superconductivity in cuprates [1,2] or induce a chiral state in Kagome metals [3].
To maximize surface strains, we exploit the enhanced yield strain of micron-scale materials, well-stud-ied in materials science [4]. State-of-the-art microfabrication using focused ion beam techniques allow precise design of crystalline samples, achieving desired strain fields such as uniaxial stress or more complex strain gradients [5]. We microcarve the entire sample into a flexible cantilever without a sub-strate and then bend it, enabling arbitrary and especially out-of-plane tensile strain even in layered quantum materials [6].
Raman scattering directly probes long-wavelength phonon modes, which are highly sensitive to lattice strain. With submicrometer spatial resolution, it provides a direct measure of strain variations. It also detects local symmetry breaking and gives access to electronic, magnetic, and orbital excitations, prob-ing the electronic ground state. Even without a change in lattice symmetry under stress, the phonon mode frequency serves as an extremely sensitive probe, determined with high energy resolution.
The layered crystal structure of delafossite PdCoO2, with weak interlayer coupling, makes it an ideal candidate for studying out-of-plane tensile strain. Its exceptional purity [7] minimizes extrinsic disorder effects. Among the various Raman modes allowed by group theory, the fully symmetric A1g phonon, consisting of oxygen ion vibrations along the c-direction [8], is particularly interesting. Finite element simulations guide the design of a cantilever manufactured from high-quality single crystals of PdCoO2. Together with DFT-calculations our Micro-Raman measurements confirm quantitively the spatial strain distribution on the cantilever. Furthermore, we investigate the role of the amorphous layer thickness for Raman spectra.

CANCRINITE-GROUP MINERALS AT NON-AMBIENT CONDITIONS: A MODEL OF THE ELASTIC BEHAVIOR AND STRUCTURE EVOLUTION
Creators: name: LOTTI, PAOLO
Publisher: name: Universit� degli Studi di Milano
Year: 2014

description: The minerals of the cancrinite group are zeolite-like compounds, sharing the [CAN]-topology of the framework. Their structure shows large 12-ring channels along [0001], bound by columns of cages, the so-called can units. Natural and synthetic compounds exhibit a remarkable chemical variability. Among the natural species, the majority shows an aluminosilicate framework. Two subgroups can be identified according to the extraframework content of the can units: the cancrinite- and the davyne-subgroups, showing Na-H2O and Ca-Cl chains, respectively. The channels are stuffed by cations, anions and molecules. In Nature, cancrinite-group minerals occur in the late/hydrothermal stages of alkaline (SiO2)-undersaturated magmatism and in related effusive or contact rocks. Cancrinite-group compounds have been proposed as stable storage form for alkaline wastes. The characterization of the phase-stability fields, thermo-elastic behavior and structure response to applied (P,T) is needed to evaluate and predict their behavior in natural and industrial processes. The present study aimed to model the thermo-elastic behavior and the mechanisms of (P,T)-induced structure evolution of cancrinite-group minerals, with a special interest on the role played by the extraframework population. The study was restricted to the following (CO3)-rich and (SO4)-rich end-members: cancrinite {[(Na,Ca)6(CO3)1.2-1.7][Na2(H2O)2][Al6Si6O24]}, vishnevite {[(Na,Ca,K)6(SO4)][Na2(H2O)2][Al6Si6O24]}, balliranoite {[(Na,Ca)6(CO3)1.2-1.7][Ca2Cl2][Al6Si6O24]} and davyne {[(Na,Ca,K)6((SO4),Cl)][Ca2Cl2][Al6Si6O24]}. Their high-P and low-T (T < 293 K) behavior was investigated by means of in situ single crystal X-ray diffraction, using diamond-anvil cells and (N2)-cryosystems, respectively. Though sharing a similar volume compressibility and thermal expansivity, these minerals have a different thermo-elastic anisotropy, more pronounced in the cancrinite-subgroup compounds. This behavior is governed by different deformation mechanisms, which reflect the different coordination environments of the cage population between the minerals of the two subgroups. The davyne sample studied at high-P showed a displacive phase transition from the P63/m to the P63 space group after the load of pressure [0.0001 ? P (GPa) ? 0.38(2)]. In vishnevite, a P-induced re-organization of the extraframework population took place at P > 3.5 GPa, coupled with a significant increase in compressibility, suggesting that the channel-constituents can also play an active role at non-ambient conditions. Besides common features likely ascribable to the [CAN]-topology, the nature of the extraframework population appears to control significantly the (P,T)-induced structure evolution and thermo-elastic behavior of the cancrinite-group compounds.

description: We analyze the impact of loss in lattices of coupled optical waveguides and find that in such case, the hopping between adjacent waveguides is necessarily complex. This results not only in a transition of the light spreading from ballistic to diffusive, but also in a new kind of diffraction that is caused by loss dispersion. We prove our theoretical results with experimental observations.

Here we present the results of palaeobotanical, sedimentological and archaeological analyses performed on three small well features from the Roitzschjora site. Our results prove that these group of features could serve as valuable palaeoenvironmental on-site records in spite of their poor preservation and small extent. The may espacially contribute to our general understanding of water management in comparatively dry environments and a more realistic assessment of the vulnerablity of these societies to small-scaled hydrological changes.

Fiber-Optic Interferometry Using Narrowband Light Source and Electrical Spectrum Analyzer: Influence on Brillouin Measurement

description: We observe an interference pattern using a simple fiber-optic interferometer consisting of an electrical spectrum analyzer and a narrowband light source, which is commonly employed for observing the Brillouin gain spectrum. This interference pattern expands well beyond the frequency range corresponding to the Brillouin frequency shift in silica fibers (approximately 11 GHz at 1550 nm). Using both silica single-mode and polymer optical sensing fibers, we then experimentally prove that the distinctive noise in a self-heterodyne-based Brillouin measurement with an unoptimized polarization state originates from the interference between the reference light and the Fresnel-reflected light. This noise can be almost completely suppressed by employing a delay line that is longer than the coherence length of the light source and by artificially applying a high loss near the open end of the sensing fiber.

description: Clusters of galaxies are powerful probes for testing our cosmological paradigm, especially dark energy models. However, some obstacles prevent us from using clusters to their full potential, from being able to precisely detect them, to accurately determining their characteristics. In this work, we explore how modern machine-learning algorithms can be used to help with the cosmological exploitation of clusters of galaxies. More specifically, we adapted the detection-oriented neural network YOLO (Redmon & Farhadi 2018) to detect clusters of galaxies inside images of galaxy surveys, using as training the Sloan Digital Sky Survey (SDSS) and galaxy clusters previously identified by the redMaPPer algorithm (Rykoff et al. 2014). Our results indicate that our novel network, dubbed YOLO-CL, is able to reach a consistently high level of purity and completeness over a wide variety of reference cluster samples, even outperforming redMaPPer in certain cases. As such, this work shows the potential of exploring the performance of deep convolution networks for future cosmological cluster surveys (LSST, Euclid, ...).

description: Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23 Short abstract The NOAA STAR SOCD OceanView (OV) v1.0 was publicly released in May-2021 at https://www.star.nesdis.noaa.gov/socd/ov/. The OV is a web-based application delivering an integrated display of remote sensing, in situ, and model data over oceans, polar areas, coastal and inland waterways. It incorporates products primarily from NOAA and some from NASA and other sources, spanning satellites, aircraft, and models. This visualization tool is still evolving and has several modules, including an experimental thermal front module capable of deriving and interactively visualizing level-4 fronts. The overall long-term activities of GHRSST Climatology and L4 Inter-comparison Task Team (IC-TT) 3 are to: 1. Validate L2, L3, and L4 SST gradients in highly variable regions using SailDrones 2. Produce an online visualization tool for L4-SST gradients 3. Develop the science to calculate fronts and intercompare 4. Validate SST gradients/fronts with other independent but related data, e.g., salinity gradients or altimeter currents 5. Compare feature resolution and its spatial consistency across marine regions 6. Compare SST gradients over seasonal and interannual time scales The OceanView tool contributes explicitly to #2 above, will potentially contribute to #3 and #4, and for general visualization purposes. It offers an interactive visualization with various filters to sub-select fronts and a profiler to analyze individual fronts. Currently, it has only one L4 SST front (NOAA GOES-POES blended). However, the system is scalable and will be expanded depending on identified needs and the path forward. This preliminary presentation aims to gauge features of interest and potential extension to meet GHRSST TT objectives.

third sexual phenotype

description: Sexually dimorphic behaviours, such as parental care, have long been thought to be mainly driven by gonadal hormones. In the past two decades, a few studies have challenged this view, highlighting the direct influence of the sex chromosome complement (XX vs XY or ZZ vs ZW). The African pygmy mouse, Mus minutoides, is a wild mouse species with naturally occurring XY sex reversal induced by a third, feminizing X* chromosome, leading to three female genotypes: XX, XX* and X*Y. Here, we show that sex reversal in X*Y females shapes a divergent maternal care strategy (maternal aggression, pup retrieval and nesting behaviours) from both XX and XX* females. Although neuroanatomical investigations were inconclusive, we show that the dopaminergic system in the anteroventral periventricular nucleus of the hypothalamus is worth investigating further as it may support differences in pup retrieval behaviour between females. Combining behaviours and neurobiology in a rodent subject to natural selection, we evaluate potential candidates for the neural basis of maternal behaviours and strengthen the underestimated role of the sex chromosomes in shaping sex differences in brain and behaviours. All things considered, we further highlight the emergence of a third sexual phenotype, challenging the binary view of phenotypic sexes.

description: The peritoneum, pleura, and pericardium are yet understudied multicellular systems where mesothelial cells (MCs) and endothelial cells (ECs) are in close proximity. Crosstalk between these cell types likely plays role in molecular transport, immunological reactions, and metabolic processes in health, disease, and therapeutic intervention. In this review, we discuss recent proteomic efforts to characterize the crosstalk between MC and EC. We describe the proteomic methods necessary for investigation of crosstalk between MC and EC, as well as the in-vitro models that can be employed. Potential experimental approaches range from conditioned medium, via co-culture on semi-permeable membranes, to 3D cell culture based organoid models. While the biological and clinical relevance of the models may increase with their ability to mimic close cell communication, the practicality of these complex experiments corresponds vice versa, making standardization more difficult and expensive. Currently, data and reports on mesothelial-to-endothelial crosstalk are still very scarce. In our opinion, the in-vitro model using semi-permeable cell culture inserts will allow to establish a basic understanding of cellular crosstalk that may occur between those cell types. Later-on, more sophisticated 3D cell cultures may be better able to simulate the transport dynamics within the peritoneal membrane.

description: We report the discovery of a new faint dwarf galaxy, which we dub Scl-MM-Dw1, at a projected distance of $\sim$65 kpc from the spiral galaxy NGC 253. The discovery results from the Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS), a program with the Magellan/Megacam imager to study faint substructure in resolved stellar light around massive galaxies outside of the Local Group. We measure a tip of the red giant branch distance to Scl-MM-Dw1 of $D$=3.9$\pm$0.5 Mpc, consistent with that of NGC 253, making their association likely. The new dwarf's stellar population is complex, with an old, metal poor red giant branch ($\gtrsim$10 Gyr, [Fe/H]$\sim$$-$2), and an asymptotic giant branch with an age of $\sim$500 Myr. Scl-MM-Dw1 has a half-light radius of $r_{h}$=340$\pm$50 pc and an absolute magnitude of $M_{V}$=$-$10.3$\pm$0.6 mag, comparable to the Milky Way's satellites at the same luminosity. Once complete, our imaging survey of NGC 253 and other nearby massive galaxies will provide a census of faint substructure in halos beyond the Local Group, both to put our own environment into context and to confront models of hierarchical structure formation.

description: Departing from two recently dated finds of human bones in wetlands from the area of Falbygden in western Sweden, this paper describes the finds in detail and sets them in a wider context of depositional practices in the south Scandinavian Early Neolithic. The two finds are both of girls in the age of 15-20 years, and in one of the cases it is probable that she was bound and possibly intentionally drowned in shallow water. The Falbygden finds have clear parallels in Denmark and in southern Sweden in the same period. The Danish material indicates that a particular segment of the population was treated in this way, primarily young individuals around 15-20 years. Some of them show signs of disease or deformations, many have signs of trauma, and a couple have been found with cords around the neck, suggesting violent deaths. In a number of cases, they were also found in pairs. One of the Falbygden finds, the so-called Hallonflickan, was also unusual in that her Sr isotope ratio indicates that the was born far away, probably in Scania in southern Sweden. Whether other finds of this kind were also long distance movers is not known. Direct bone datings show that this practice is established at the same time as the introduction of agriculture and of the Funnel Beaker culture in Scandinavia, around 4000 BC, and continues until ca 3000 BC after which it disappears for ca 1000 years. Deposition of humans in wetlands is paralleled by deposition of animals, pottery and stone tools, and we suggest that these form parts of a complex of ritual practices established over a large area at the time of the earliest Scandinavian agriculture.

description: Solar and extrasolar planets are the subject of numerous studies aiming to determine their chemical composition and internal structure. In the case of extrasolar planets, the composition is important as it partly governs their potential habitability. Moreover, observational determination of chemical composition of planetary atmospheres are becoming available, especially for transiting planets. The present works aims at determining the chemical composition of planets formed in stellar systems of solar chemical composition. The main objective of this work is to provide valuable theoretical data for models of planet formation and evolution, and future interpretation of chemical composition of solar and extrasolar planets. We have developed a model that computes the composition of ices in planets in different stellar systems with the use of models of ice and planetary formation. We provide the chemical composition, ice/rock mass ratio and C:O molar ratio for planets in stellar systems of solar chemical composition. From an initial homogeneous composition of the nebula, we produce a wide variety of planetary chemical compositions as a function of the mass of the disk and distance to the star. The volatile species incorporated in planets are mainly composed of H2O, CO, CO2, CH3OH, and NH3. Icy or ocean planets have systematically higher values of molecular abundances compared to giant and rocky planets. Gas giant planets are depleted in highly volatile molecules such as CH4, CO, and N2 compared to icy or ocean planets. The ice/rock mass ratio in icy or ocean and gas giant planets is, respectively, equal at maximum to 1.01+-0.33 and 0.8+-0.5, and is different from the usual assumptions made in planet formation models, which suggested this ratio to be 2-3. The C:O molar ratio in the atmosphere of gas giant planets is depleted by at least 30% compared to solar value.

description: با توجه به سرمایه‌گذاری‌ زیادی که امروزه سازمان‌های مختلف بخصوص سازمان‌های دانش‌بنیان در زمینه‌ی فناوری اطلاعات انجام می‌دهند، آنچه که بسیار مهم است این است که فناوری اطلاعات بعنوان یک منبع استراتژیک در جهت رسیدن به اهداف استراتژیک، مورد استفاده قرار گیرد. در این ارتباط تحقیقات زیادی انجام شده و مدل‌ها و چارچوب‌های نظری مختلفی ارائه شده است. اما به جهت وجود رویکردهای متفاوت در این زمینه، مفهوم روشنی از همسویی استراتژیک بدست نمی‌آید. سازمان‌دانش‌بنيان مجموعه‌اي از افراد و منابع پشتيبان هستند كه دانش را از طريق تعاملات پيوسته، خلق و از آن استفاده مي‌كند. محدوده‌هاي آن نامشخص، منعطف و پوياست. لذا در این تحقیق بدنبال شناسایی شاخص‌ها، ارزیابی عوامل موثر و ارائه تحلیل نظری حاصل از یافته‌های تحقیق، جهت تبیین مفهوم همسویی استراتژیک فناوری اطلاعات هستیم که از منظر و رویکرد جامعی برخوردار باشد. در این تحقیق با بررسی مشهورترین چارچوب‌ها و تحقیقات انجام شده مرتبط با حوزه همسویی استراتژیک، شاخص‌های اصلی برای همسویی شناسایی می‌شوند.

description: The non-profit association National Research Data Infrastructure (NFDI) promotes science and research through a National Research Data Infrastructure. Its aim is to develop and establish an overarching research data management (RDM) for Germany and to increase the efficiency of the entire German science system. After a two-and-a-half year build up phase, the process of adding new consortia, each representing a different data domain, has ended in March 2023. NFDI now has 26 disciplinary consortia (and one additional basic service collaboration). Now the full extent of cross-consortial interaction is beginning to show.

The attached table of jointly documented cross-consortial collaborations is based on a White Paper ratified by the NFDI association’s consortia assembly in January 2023. It defines collaborations as “the exchange of information on or development of common approaches to managing the research data of at least one domain.” From the perspective of the consortia assembly, “A necessary condition for any collaboration is that activities are on behalf and in line with the strategic aims of a consortium and are not activities by individuals within them only.” As the consortia were established in three separate rounds with roughly a year in between, some consortia have had more opportunities to participate in the NFDI association than others which shows in their higher levels of interaction. We expect these differences to diminish over time with further updates of this dataset.

The tabular overview of the collaborations was created as a collaborative work in which all consortia had the opportunity to enter joint activities. Nevertheless, this document does not claim to be complete. Instead, it should be understood as a first version; future collaboration will be added and the document will be published in updated versions.

description: The perturbative $α^{\prime}$ corrections to Type-IIA String Theory compactified on a Calabi-Yau three-fold allow the construction of regular three-charge supersymmetric black holes in four dimensions, whose entropy scales with the charges as $S \sim \left( p^1 p^2 p^3\right)^{\frac{2}{3}} $. We construct an M-theory uplift of these quantum black holes and show that they can be interpreted as arising from three stacks of M2 branes on a conical singularity. This in turns allow us relate them via a series of dualities to a system of D3 branes carrying momentum and thus to give a microscopic interpretation of their entropy.

description: Η αρχή της αναλογικότητας αποτελεί γενική αρχή δικαίου, η οποία κατοχυρώνεται δημοκρατικά στο εθνικό Σύνταγμα και στο ενωσιακό δίκαιο, δεσμεύοντας κάθε έκφανση της κρατικής λειτουργίας. Φυσικό της χώρο αποτελεί η διακριτική ευχέρεια της περιοριστικής δημόσιας διοίκησης , στη δράση της οποίας θέτει τα άκρα όρια, αρτιώνοντας τη νομιμότητά της. Αναπτύσσεται σε συγκρουσιακό επίπεδο στο πεδίο των θεμελιωδών δικαιωμάτων, λειτουργώντας ως εξισορροπητικό εργαλείο. Το μοτίβο της επίκλησής της περιλαμβάνει την ύπαρξη θεμιτού δημόσιου σκοπού για τον περιορισμό έννομου συμφέροντος ή θεμελιώδους δικαιώματος, την προσφορότητα του περιοριστικού μέσου και την αναγκαιότητα αυτού. Η αρχή της αναλογικότητας αποκτά ρυθμιστικό ρόλο και τυγχάνει ευρείας εφαρμογής κατά την αστυνομική δράση, η οποία αποτελεί την κατεξοχήν έκφανση της περιοριστικής δημόσιας διοίκησης. Αιτιολογική βάση και αναγκαιότητα επίκλησής της αποτελεί η διττή αποστολή της Ελληνικής Αστυνομίας, η οποία επιδιώκει την εξασφάλιση των κοινών αγαθών της δημόσιας τάξης και ασφάλειας από τη μία πλευρά και την προστασία των έννομων συμφερόντων και θεμελιωδών δικαιωμάτων των πολιτών από την άλλη. Στόχος της παρούσας έρευνας είναι αρχικά να αποκρυσταλλωθούν τα στοιχεία της αναλογικότητας κατά την αστυνομική δράση, ώστε να καταστεί πιο εύκολη τόσο η επίκλησή της από τους αστυνομικούς, όσο και ο έλεγχος τυχόν απόκλισης από αυτήν. Στη συνέχεια, επιδιώκεται να εξεταστεί η πληρότητα της νομοθετικής και θεσμικής πρόβλεψης της αρχής της αναλογικότητας στη δράση των αστυνομικών, ώστε να αποτελεί απαράβατο γνώμονα των ενεργειών τους. Τέλος, ερευνάται η επάρκεια της παρεχόμενης αστυνομικής εκπαίδευσης και μετεκπαίδευσης ως προς την αρχή της αναλογικότητας, μέσω των υφιστάμενων Αστυνομικών Σχολών, διατυπώνοντας παράλληλα ανάλογα συμπεράσματα και προτάσεις, στην κατεύθυνση μιας περισσότερο εφαρμοσμένης προσέγγισης της εν λόγω αρχής κατά την αστυνομική δράση.

description: Every bi-uniform matroid is representable over all sufficiently large fields. But it is not known exactly over which finite fields they are representable, and the existence of efficient methods to find a representation for every given bi-uniform matroid has not been proved. The interest of these problems is due to their implications to secret sharing. The existence of efficient methods to find representations for all bi-uniform matroids is proved here for the first time. The previously known efficient constructions apply only to a particular class of bi-uniform matroids, while the known general constructions were not proved to be efficient. In addition, our constructions provide in many cases representations over smaller finite fields.

description: We study the orbital angular momentum (OAM) $L_z$ in two dimensional chiral $(p_x+ip_y)^ν$-wave superfluids (SF) of $N$ fermions on a disc at zero temperature, in terms of spectral asymmetry and spectral flow. It is shown that $L_z=νN/2$ for any integer $ν$, in the BEC regime. In contrast, in the BCS limit, while the OAM is $L_z=N/2$ for the $p+ip$-wave SF, for chiral SF with $ν\geq2$, the OAM is remarkably suppressed as $L_z=N\times O(Δ_0/\varepsilon_F)\ll N$, where $Δ_0$ is the gap amplitude and $\varepsilon_F$ is the Fermi energy. We demonstrate that the difference between the $p+ip$-wave SF and the other chiral SFs in the BCS regimes originates from the nature of edge modes and related depairing effects.

description: In this work, novel copolymer hydrogel was designed from acrylamide (AAm) and 3-Allyloxy-2-hydroxy-1-propanesulfonic acid sodium salt (AHPS) through the free radical mechanism to produce an efficient adsorbent for removing the methylene blue dye from its aqueous solution. Tracking the gel fraction showed a decrease by increasing the AHPS concentration. The obtained polymers were characterised by FTIR, TGA, and SEM. The swelling behaviour was investigated, and the results indicated the enhancement in the swelling ratio for the hydrogels containing AHPS, and the maximum swelling ratio (4353.8%) was achieved after increasing the molar ratio of AHPS to 15%. The influence of different parameters such as contact time, dye concentration, pH, polymer dose, and temperature on the adsorption of methylene blue was studied. Studying the adsorption kinetics and isotherm showed that the adsorption process was well described by the pseudo-second-order and the Langmuir model, and the maximum adsorption capacity (qm) was 703.2 mg/g. Estimation of the thermodynamic parameters showed negative values of ∆G indicating the spontaneous nature of the adsorption process, the positive ∆H value (13.7 kJ mol−1) confirming the endothermic nature of MB adsorption, and the positive value of ∆S (0.048 KJ K−1 mol−1) indicating increased randomness at the solid/solution interface.

description: The extensible N-Dimensional Data Format (NDF) was designed and developed in the late 1980s to provide a data model suitable for use in a variety of astronomy data processing applications supported by the UK Starlink Project. Starlink applications were used extensively, primarily in the UK astronomical community, and form the basis of a number of advanced data reduction pipelines today. This paper provides an overview of the historical drivers for the development of NDF and the lessons learned from using a defined hierarchical data model for many years in data reduction software, data pipelines and in data acquisition systems.
