description: Cryopreservation can be used to store equine oocytes for extended periods so that they can be used in artificial reproduction technologies at a desired time point. It requires use of cryoprotective agents (CPAs) to protect the oocytes against freezing injury. The intracellular introduction of CPAs, however, may cause irreversible osmotic damage. The response of cells exposed to CPA solutions is governed by the permeability of the cellular membrane towards water and the CPAs. In this study, a mathematical mass transport model describing the permeation of water and CPAs across an oocyte membrane was used to simulate oocyte volume responses and concomitant intracellular CPA concentrations during the exposure of oocytes to CPA solutions. The results of the analytical simulations were subsequently used to develop a phenomenological finite element method (FEM) continuum model to capture the response of oocytes exposed to CPA solutions with spatial information. FEM simulations were used to depict spatial differences in CPA concentration during CPA permeation, namely at locations near the membrane surface and towards the middle of the cell, and to capture corresponding changes in deformation and hydrostatic pressure. FEM simulations of the multiple processes occurring during CPA loading of oocytes are a valuable tool to increase our understanding of the mechanisms underlying cryopreservation outcome. © 2021, The Author(s).
Virtuelle Realitäten, echte Partizipation: über Herausforderung und Chancen der Bürger:innenbeteiligung im Metaverse

description: 2021 stellte Meta Platforms seine Vision des Metaverse vor und löste damit eine Debatte über die Zukunft der digitalen Welt aus. Während einige das Metaverse als eine vielversprechende neue Umgebung betrachten, sehen andere darin eine potenzielle Bedrohung für unsere bereits polarisierte Welt oder einen Ort an dem Menschen in alternative Realitäten flüchten. In Anlehnung an die Erwartungen und Bedenken, die zu Beginn der 2010er Jahre im Zusammenhang mit sozialen Online-Netzwerken geäußert wurden, stellt sich die Frage, wer dafür sorgen wird, dass das Metaverse, sollte es „the next big thing“ werden, ein demokratischer und deliberativer Raum ist. Wie kann demokratische Teilhabe im Metaverse ganz konkret aussehen? Wie könnten beispielsweise Städte und Kommunen immersive Systeme nutzen um Bürger:innen teilhaben zu lassen? Plattformen der digitalen Beteiligung ermöglichen es Bürger:innen, sich asynchron und ortsunabhängig an lokalen Entscheidungsfindungsprozessen, wie etwa der Stadtplanung, zu beteiligen. Gleichzeitig gelingt es diesen Plattformen aber nicht, die breite Bevölkerung abzuholen. Dies liegt einerseits an generellen Hürden von Beteiligungsprozessen, anderseits an der Usability der digitalen Tools. In verschiedenen Studien konnten Vorteile des Einsatzes von immersiven Systeme für die partizipative Stadtplanung herausgearbeitet werden. In dem Beitrag sollen Ergebnisse vorgestellt und zugleich diskutiert werden, wie Städte und Kommunen das Metaverse für sich nutzen können, um ihre Bürger:innen an Weiterentwicklungen ihres direkten Umfelds teilhaben zu lassen. Ansätze digitaler Twins sollen vorgestellt und zugleich erörtert werden, wie im Sinne einer Demokratisierung der Technologieentwicklung inklusivere immersive Systeme gemeinsam mit verschiedenen Akteuren entwickelt werden können.

description: We investigate a recent proposal for a distinguished vacuum state of a free scalar quantum field in an arbitrarily curved spacetime, known as the Sorkin-Johnston (SJ) vacuum, by applying it to de Sitter space. We derive the associated two-point functions on both the global and Poincaré (cosmological) patches in general d+1 dimensions. In all cases where it is defined, the SJ vacuum belongs to the family of de Sitter invariant alpha-vacua. We obtain different states depending on the spacetime dimension, mass of the scalar field, and whether the state is evaluated on the global or Poincaré patch. We find that the SJ vacuum agrees with the Euclidean/Bunch-Davies state for heavy ("principal series") fields on the global patch in even spacetime dimensions. We also compute the SJ vacuum on a causal set corresponding to a causal diamond in 1+1 dimensional de Sitter space. Our simulations show that the mean of the SJ two-point function on the causal set agrees well with its expected continuum counterpart.

description: Evidence of a new particle with mass ~125 GeV decaying into a pair of tau leptons at the Large Hadron Collider spurs interest in ascertaining its spin in this channel. Here we present a comparative study between spin-0 and spin-2 nature of this new particle, using spin correlations and decay product directions. The TauSpinner algorithm is used to re-weight distributions from qqbar -> gamma/Z -> tau+ tau- sample to simulate a spin-2 state exchange. The method is based on supplementing the Standard Model matrix elements with those arising from presence of a new interaction. Studies with simulated samples demonstrate the discrimination power between these spin hypotheses based on data collected at the Large Hadron Collider.

description: In this paper, an optimization approach was presented for the flexural strength and stiffness design of reinforced concrete beams. Surrogate modeling based on machine learning was applied to predict the responses of the structural system in three-point flexure tests. Three design input variables, the area of steel bars in the compression zone, the area of steel bars in the tension zone, and the area of steel bars in the shear zone, were adopted for the dataset and arranged by the Box-Behnken design method. The dataset was composed of thirteen specimens of reinforced concrete beams. The specimens were tested under three-points flexure loading at the age of 28 days and both the failure load and the maximum deflection values were recorded. Compression and tension tests were conducted to obtain the concrete data for the analysis and numerical modeling. Afterward, finite element modeling was performed for all the specimens using the ATENA program to verify the experimental tests. Subsequently, the surrogate models for the flexural strength and the stiffness were constructed. Finally, optimization was conducted supporting on the factorial method for the predicted responses. The adopted approach proved to be an excellent tool to optimize the design of reinforced concrete beams for flexure and stiffness. In addition, experimental and numerical results were in very good agreement in terms of both the failure type and the cracking pattern. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

description: We present the results of a 22GHz H2O maser survey toward a new sample of AGB and post-AGB star candidates. Most of the objects are selected for the first time based on the AKARI data, which have high flux sensitivity in the mid-infrared ranges. We aim at finding H2O maser sources in the transient phase between the AGB and post-AGB stage of evolution, where the envelopes start to develop large deviations from spherical symmetry. The observations were carried out with the Effelsberg 100m radio telescope. Among 204 observed objects, 63 detections (36 new) were obtained. We found 4 objects which may be "water fountain" sources (IRAS 15193+3132, IRAS 18056-1514, OH 16.3-3.0, and IRAS 18455+0448). They possess an H2O maser velocity coverage much smaller than those in other known water fountains. However, the coverage is still larger than that of the 1612MHz OH maser. It implies that there is an outflow with a higher velocity than the envelope expansion velocity (typically <25 km/s), meeting the criterion of the water fountain class. We suggest that these candidates are possibly oxygen-rich late AGB or early post-AGB stars in a stage of evolution immediately after the spherically symmetric AGB mass-loss has ceased.

18/187),
• Leistungsverbesserungen in der Gesetzlichen Rentenversicherung (RV-Leistungsverbesserungsgesetz)
(Bundestagsdrucksache 18/909)

Kurz gefasst

Die viele Jahre dominierende Strategie der Leistungseinschnitte in der Rentenversicherung wird durch Leistungsverbesserungen abgelöst. Diese sind dringend erforderlich, weil die sozialen Probleme im Alter zunehmen. Gleichwohl wird damit das Zentralproblem, nämlich die Abkoppelung der Rentenanpassungen von der Lohnentwicklung und die damit einhergehende Absenkung des Rentenniveaus, nicht gelöst. Das vor dem Hintergrund der Umbrüche auf dem Arbeitsmarkt steigende Risiko der Altersarmut bleibt virulent.
Die systemwidrige Finanzierung der Mütterrente aus Beitrags- statt aus Steuermitteln verringert den Spielraum für eine Stabilisierung des Rentenniveaus. Hinzu kommt, dass das zusätzliche Rentenvolumen und die Belastung der Beitragszahler dazu führen, dass das Rentenniveau noch zusätzlich nach unten gedrückt wird. Die Zielsetzung der Lebensstandardsicherung gerät immer stärker in den Hintergrund.
Die zeitlich begrenzte Sonderregelung der abschlagsfreien Rente mit 63 (unter der Bedingung von 45 Beitragsjahren) mildert die Probleme des Altersübergangs für besonders langjährig Versicherte. Aber es handelt sich um eine selektive Begünstigung einzelner Gruppen. Anhaltspunkte für eine bevorstehende "Frühverrentungswelle" gibt es nicht.
Besonders stark von niedrigen Renten sind die Erwerbsgeminderten betroffen. Die Anerkennung von zusätzlichen zwei Jahren Zurechnungszeiten und die Günstigerprüfung sind wichtige Beiträge zur Erhöhung der Renten. Allerdings gelten die Verbesserungen nur für den Rentenzugang und nicht für den Bestand. Auch bleibt es bei der Erhebung von Abschlägen.

description: In this paper we study the influence of the cloud microphysical parameterization on large-eddy simulations of radiation fog. A deep fog case as observed at Cabauw (Netherlands) is investigated using high-resolution large-eddy simulations with different microphysics treatments for activation and diffusional growth. A comparison of the results indicates that the commonly applied assumption of saturation adjustment produces at maximum 6.9 % higher liquid water paths compared to the explicit diffusional growth method but has no significant influence on the general life cycle of the fog layer. Differences are found to be the most pronounced at the top of the fog layer where the highest supersaturations occurs. Furthermore, the effect of different cloud droplet number concentrations is investigated by using a selection of common activation schemes. We find, in line with previous studies, a positive feedback between the cloud droplet number concentration and both the optical thickness and the strength of the fog layer. Furthermore, we perform an explicit analysis of the budgets of microphysical quantities in order to assess which processes have the largest spatial and temporal influence on the development of the fog layer.

description: At high energy the standard model possesses conformal symmetry at the classical level. This is reflected at the quantum level by relations between the different beta functions of the model. These relations are known as the Weyl consistency conditions. We show that it is possible to satisfy them order by order in perturbation theory, provided that a suitable coupling constant counting scheme is used. As a direct phenomenological application, we study the stability of the standard model vacuum at high energies and compare with previous computations violating the Weyl consistency conditions.

Creators: name: Heidenreich, Stephan M.
Publisher: name: University Library Heidelberg
Year: 2016

description: Während die früheste Besiedlung der amerikanischen Kontinente nach wie vor Inhalt der Forschungsdebatte ist, so wird deren Ursprung zumeist in der als Beringia bezeichneten arktischen und subarktischen Region Nordamerikas und Nordostasiens gesucht. Intensive Forschungen der letzten Jahrzehnte – vor allem in Alaska – konnten die Kenntnis der frühesten Besiedlung dieses Raumes erheblich erweitern. Der vorliegende Beitrag gibt einen repräsentativen Überblick über spätpleistozäne Steingeräteinventare Alaskas. Anstelle von kultur chronologischen Unterschieden erscheint funktionale Variabilität mit einem variablen System technologischer Organisation eine plausiblere Erklärung für die verschiedenartig zusammengesetzten Inventare zu sein. Die Frage nach dem Ausbreitungsweg der Erstbesiedlung Amerikas muss derweil weiter offenbleiben. Der archäologische Befund Beringias zeigt keine eindeutigen Verbindungen zum kontinentalen Nordamerika. Dies schmälert jedoch keinesfalls die Bedeutung der spätpleistozänen Funde Alaskas, insbesondere aufgrund ihrer Aussagekraft hinsichtlich der Besiedlung zuvor unbewohnter Gebiete durch pleistozäne Jäger und Sammler.
description: While the peopling of the Americas is still subject of debate in archaeological research, most scholars agree that its origin can be found in the arctic and subarctic regions of Northeastern Asia and Northwestern America, often referred to as Beringia. Intensive research in recent decades – especially in Alaska – has led to a growing body of evidence for the colonisation of these areas. This paper gives a representative overview of Late Pleistocene stone tool assemblages from Alaska. It appears that instead of a cultural-chronological organisation, functional variability with a diverse system of technological organisation seems a more plausible explanation for the variable composition of these assemblages. Meanwhile, the question of the migration route in the course of the peopling of the Americas must remain open. But this does not deprive the Alaskan record of its general relevance, especially regarding its significance for statements on colonisation processes of Pleistocene hunter-gatherers.

description: To understand the origin of water line emission and absorption during high-mass star formation, we decompose high-resolution Herschel-HIFI line spectra toward 19 high-mass star-forming regions into three distinct physical components. Protostellar envelopes are usually seen as narrow absorptions or emissions in the H2O 1113 and 1669 GHz ground-state lines, the H2O 987 GHz excited-state line, and the H2O-18 1102 GHz ground-state line. Broader features due to outflows are usually seen in absorption in the H2O 1113 and 1669 GHz lines, in 987 GHz emission, and not seen in H2O-18, indicating a low column density and a high excitation temperature. The H2O 1113 and 1669 GHz spectra show narrow absorptions by foreground clouds along the line of sight, which have a low column density and a low excitation temperature, although their H2O ortho/para ratios are close to 3. The intensities of the H2O 1113 and 1669 GHz lines do not show significant trends with luminosity, mass, or age. In contrast, the 987 GHz line flux increases with luminosity and the H2O-18 line flux decreases with mass. Furthermore, appearance of the envelope in absorption in the 987 GHz and H2O-18 lines seems to be a sign of an early evolutionary stage. We conclude that the ground state transitions of H2O trace the outer parts of the envelopes, so that the effects of star formation are mostly noticeable in the outflow wings. These lines are heavily affected by absorption, so that line ratios of H2O involving the ground states must be treated with caution. The average H2O abundance in high-mass protostellar envelopes does not change much with time. The 987 GHz line appears to be a good tracer of the mean weighted dust temperature of the source, which may explain why it is readily seen in distant galaxies.

description: Am Südsattel des Mallnitzer Tauern wurde vor Kurzem ein zweiter Münzopferplatz entdeckt. Die Münzen setzen sich aus 16 Obolen und einem As der römisch republikanischen Zeit zusammen. Die ältesten Münzen gehören hier einer frühen Gruppe von Obolen mit einer Prägezeit um die Mitte des 2. Jahrhunderts v. Chr. an, während die bisherigen Kleinsilbermünzen der anderen Münzopferstellen am Mallnitzer Tauern erst gegen Ende des 2. Jahrhunderts v. Chr. einsetzen. Die Münzen sind teils norischer, teils tauriskischer Herkunft, ein Obol stammt aus dem vindelikischen Gebiet nördlich der Alpen. Die besondere Bedeutung des Passes steht wahrscheinlich mit dem keltischen und römischen Abbau von Gold- und Silbererzen in der Region unmittelbar nördlich davon in einem engen Zusammenhang. Die hier geopferten Münzen belegen überregionale wirtschaftliche Kontakte zwischen dem Südostalpengebiet und dem heutigen Südbayern.
description: In the vicinity of the southern passage of the Mallnitzer Tauern pass a further offering site was discovered in 2011. The coinage consists of 16 oboli and an as of the Roman Republic. An older group of the small silver coins dates to the middle of the 2nd century BC. This is surprisingly early in comparison with the dating of all the coins from other offering sites on the Mallnitzer Tauern pass belonging to the end of the 2nd century BC. Some of the coins recovered in 2011 are of Norican, others of Tauriscan origin. One of the oboli is a Vindelican coin from the northern side of the Alps. The special importance of the Mallnitzer Tauern pass can probably be explained by gold and silver mining activities in the area just north of the pass during the Late La Tène and Roman period. The offered coins moreover prove a far distance trade between the South-eastern Alps and the modern Southern Bavaria.

description: Network-on-chip (NoC) is a new aspect for designing of future System-On-Chips (SoC) where a vast number of IP cores are connected through interconnection network. The communication between the nodes occurred by routing packets rather than wires. It supports high degree of scalability, reusability and parallelism in communication. In this paper, we present a Mesh routing architecture, which is called Diametrical 2D Mesh of Tree, based on Mesh-of-Tree (MoT) routing and Diametrical 2D Mesh. It has the advantage of having small diameter as well as large bisection width and small node degree clubbed with being the fastest network in terms of speed. The routing algorithm ensures that the packets will always reach from source to sink through shortest path and is deadlock free.

description: Analyzing the dynamics of open quantum systems has a long history in mathematics and physics. Depending on the system at hand, basic physical phenomena that one would like to explain are, for example, convergence to equilibrium, the dynamics of quantum coherences (decoherence) and quantum correlations (entanglement), or the emergence of heat and particle fluxes in non-equilibrium situations. From the mathematical physics perspective, one of the main challenges is to derive the irreversible dynamics of the open system, starting from a unitary dynamics of the system and its environment. The repeated interactions systems considered in these notes are models of non-equilibrium quantum statistical mechanics. They are relevant in quantum optics, and more generally, serve as a relatively well treatable approximation of a more difficult quantum dynamics. In particular, the repeated interaction models allow to determine the large time (stationary) asymptotics of quantum systems out of equilibrium.

description: The alkaline methanol electrooxidation reaction (MOR) in alkaline direct methanol fuel cells is still very little understood with regard to its electrochemical behavior. Theoretically, when using a rotating disk (RDE) as working electrode, the limiting current from an electrochemical reaction increases with the rotation rate as described by Levich. Contrary to this principle, the current resulting from the alkaline MOR does not increase, but decreases with rotation rate. In this work, we investigate the reason for this phenomenon using the method described by Nash and modified by Belman to quantify formaldehyde, a reaction intermediate of the alkaline methanol electrooxidation. The amount of formaldehyde is in direct relation to the rotation rate, proving that the current density loss can originate from an intensified removal of formaldehyde into the bulk solution. We analyse the influence of the electrolyte and methanol concentration on the formation of formaldehyde in order to investigate which conditions support the complete oxidation pathway and suppress the incomplete oxidation to formaldehyde. The concentration ratio as well as the absolute concentrations are of great importance for the pathways taking place. A low electrolyte concentration leads to an increase of the formaldehyde but decreasing the methanol concentration results in an absence of formaldehyde in the bulk solution.

description: Cassava is a staple food and a major source of income for many smallholder farmers. However, its yields are less than 6 t ha-1 compared to a potential yield of 20-25 t ha-1 in Zambia. Understanding cropping practices and constraints in cassava production systems is imperative for sustainable intensification. Therefore, a survey of 40 households each with three fields of cassava at 12, 24, and 36 months after planting (MAP) was conducted. Analyzed soil data, leaf area index (LAI), intercepted photosynthetically active radiation, and management practices from 120 fields were collected and subjected to descriptive statistics. To explain yield differences within the same cassava growth stage group, the data were grouped into low- and high-yield categories using the median, before applying a nonparametric test for one independent sample. Stepwise regressions were performed on each growth stage and the whole dataset to determine factors affecting tuber yield. Cassava intercropping and monocropping systems were the main cropping systems for the 12 and 24-36 MAP, respectively. Cassava yields declined by 209 and 633 kg ha-1 at 12 and 36 MAP due to soil nutrient depletion for each year of cultivation until field abandonment at 8-9 years. Fresh cassava yields ranged from 3.51-8.51, 13.52-25.84, and 16.92-30.98 t ha-1 at 12, 24, and 36 MAP, respectively. For every one unit increment in exchangeable K (cmol (+)/kg soil), cassava yield increased by 435, 268, and 406 kg ha-1 at 12, 24, and 36 MAP, respectively. One unit increment of magnesium (cmol (+)/kg soil) gave the highest yield increase of 525 kg ha-1 at 24 MAP. The low levels of soil organic carbon explained the deficient nitrogen in cassava fields, which limits the LAI growth and consequently reduced intercepted radiation and low yields. The effect of exchangeable K on growth was limited by the moderate availability of Mg and low N, thus the need for balanced fertilizer regimes. © 2021 Peter Kaluba et al.

description: We have derived ages for 13 young (<30 Myr) star-forming regions and find they are up to a factor two older than the ages typically adopted in the literature. This result has wide-ranging implications, including that circumstellar discs survive longer (~10-12 Myr) and that the average Class I lifetime is greater (~1 Myr) than currently believed. For each star-forming region we derived two ages from colour-magnitude diagrams. First we fitted models of the evolution between the zero-age main-sequence and terminal-age main-sequence to derive a homogeneous set of main-sequence ages, distances and reddenings with statistically meaningful uncertainties. Our second age for each star-forming region was derived by fitting pre-main-sequence stars to new semi-empirical model isochrones. For the first time (for a set of clusters younger than 50 Myr) we find broad agreement between these two ages, and since these are derived from two distinct mass regimes that rely on different aspects of stellar physics, it gives us confidence in the new age scale. This agreement is largely due to our adoption of empirical colour-Teff relations and bolometric corrections for pre-main-sequence stars cooler than 4000 K. The revised ages for the star-forming regions in our sample are: ~2 Myr for NGC 6611 (Eagle Nebula; M 16), IC 5146 (Cocoon Nebula), NGC 6530 (Lagoon Nebula; M 8), and NGC 2244 (Rosette Nebula); ~6 Myr for σ Ori, Cep OB3b, and IC 348; ~10 Myr for λ Ori (Collinder 69); ~11 Myr for NGC 2169; ~12 Myr for NGC 2362; ~13 Myr for NGC 7160; ~14 Myr for χ Per (NGC 884); and ~20 Myr for NGC 1960 (M 36).

description: In X-ray imaging, photons are transmitted through and absorbed by the subject, but are also scattered in significant quantities. Previous attempts to use scattered photons for biological imaging used pencil or fan beam illumination. Here we present 3D X-ray Scatter Tomography using full-field illumination. Synchrotron imaging experiments were performed of a phantom and the chest of a juvenile rat. Transmitted and scattered photons were simultaneously imaged with separate cameras; a scientific camera directly downstream of the sample stage, and a pixelated detector with a pinhole imaging system placed at 45${}^\circ$ to the beam axis. We obtained scatter tomogram feature fidelity sufficient for segmentation of the lung and major airways in the rat. The image contrast in scatter tomogram slices approached that of transmission imaging, indicating robustness to the amount of multiple scattering present in our case. This opens the possibility of augmenting full-field 2D imaging systems with additional scatter detectors to obtain complementary modes or to improve the fidelity of existing images without additional dose, potentially leading to single-shot or reduced-angle tomography or overall dose reduction for live animal studies.

description: Regulatory authorities have encouraged the usage of a monitoring (RBM) system in clinical trials before trial initiation for detection of potential risks and inclusion of a mitigation plan in the monitoring strategy. Several RBM tools were developed after the International Council for Harmonization gave sponsors the flexibility to initiate an approach to enhance quality management in a clinical trial. However, various studies have demonstrated the need for improvement of the available RBM tools as each does not provide a comprehensive overview of the characteristics, focus, and application. This research lays out a rationale for a risk methodology assessment (RMA) within the RBM system. The core purpose of RMA is to deliver a scientifically based evaluation and decision of any potential risk in a clinical trial. Thereby, a monitoring plan can be developed to elude prior identified risk outcome. To demonstrate RMA's theoretical approach in practice, a Shiny web application (R Foundation for Statistical Computing) was designed to describe the assessment process of risk analysis and visualization tools that eventually aid in focusing monitoring activities. RMA focuses on the identification of an individual risk and visualizes its weight on the trial. The scoring algorithm of the presented approach computes the assessment of the individual risk in a radar plot and computes the overall score of the trial. Moreover, RMA's novelty lies in its ability to decrease biased decision making during risk assessment by categorizing risk influence and detectability; a characteristic pivotal to serve RBM in assessing risks, and in contributing to a better understanding in the monitoring technique necessary for developing a functional monitoring plan. Future research should focus on validating the power of RMAs to demonstrate its efficiency. This would facilitate the process of characterizing the strengths and weaknesses of RMA in practice. © 2021 The Author(s)

description: Motivated by the see-saw mechanism for neutrinos which naturally generates small neutrino masses, we explore how a small GUT-scale mixing between the Standard Model Higgs and an otherwise massless hidden sector scalar can naturally generate a small mass and VEV for the new scalar which produces a false vacuum energy density contribution comparable to that of the observed dark energy dominating the current expansion of the Universe. The new scalar produces no discernible signatures in existing terrestrial experiments so that one may have to rely on other cosmological tests of this idea.

description: Knowledge of RNA structure, either in isolation or in complex, is fundamental to understand the mechanism of cellular processes. Solid-state NMR (ssNMR) is applicable to high molecular-weight complexes and does not require crystallization; thus, it is well-suited to study RNA as part of large multicomponent assemblies. Recently, we solved the first structures of both RNA and an RNA-protein complex by ssNMR using conventional 13C- and 15N-detection. This approach is limited by the severe overlap of the RNA peaks together with the low sensitivity of multidimensional experiments. Here, we overcome the limitations in sensitivity and resolution by using 1H-detection at fast MAS rates. We develop experiments that allow the identification of complete nucleobase spin-systems together with their site-specific base pair pattern using sub-milligram quantities of one uniformly labelled RNA sample. These experiments provide rapid access to RNA secondary structure by ssNMR in protein-RNA complexes of any size. © 2021 The Authors.

description: Starting from Bosma' (1981) paper, it was demonstrated by different authors that the observed shape of rotation curves of many spiral galaxies can be explained if to assume that the radial density distribution of the dark matter is correlated with the distribution of $HI$: the column densities of the dark matter and $HI$ are proportional. We show that this correlation is obviously to be an artifact and can be explained by assuming that the gas surface density is approximately equal or in general proportional to the critical density for the local gravitational stability of gaseous layer.
