description: Aims. Adaptive optics images are used to test the hypothesis that the explosive BN/KL outflow from the Orion OMC1 cloud core was powered by the dynamical decay of a non-hierarchical system of massive stars. Methods. Narrow-band H2, [Fe II], and broad-band Ks obtained with the Gemini South multi-conjugate adaptive optics (AO) system GeMS and near-infrared imager GSAOI are presented. The images reach resolutions of 0.08 to 0.10", close to the 0.07" diffraction limit of the 8-meter telescope at 2.12 microns. Comparison with previous AO-assisted observations of sub-fields and other ground-based observations enable measurements of proper motions and the investigation of morphological changes in H2 and [Fe II] features with unprecedented precision. The images are compared with numerical simulations of compact, high-density clumps moving ~1000 times their own diameter through a lower density medium at Mach 1000. Results. Several sub-arcsecond H2 features and many [Fe II] 'fingertips' on the projected outskirts of the flow show proper motions of ~300 km/s. High-velocity, sub-arcsecond H2 knots ('bullets') are seen as far as 140" from their suspected ejection site. If these knots propagated through the dense Orion A cloud, their survival sets a lower bound on their densities of order 10^7 cm^-3, consistent with an origin within a few au of a massive star and accelerated by a final multi-body dynamic encounter that ejected the BN object and radio source I from OMC1 about 500 years ago. Conclusions. Over 120 high-velocity bow-shocks propagating in nearly all directions from the OMC1 cloud core provide evidence for an explosive origin for the BN/KL outflow triggered by the dynamic decay of a non-hierarchical system of massive stars. Such events may be linked to the origin of runaway, massive stars.

description: Der Komponist und Cellist Giovanni Battista Costanzi wurde 1704 in Rom geboren. Bereits frühzeitig wurden hochrangige Kirchenvertreter auf den talentierten Musiker aufmerksam und nahmen ihn in ihre Dienste auf, so Kardinal Pietro Ottoboni (1721-1740) und Kardinal Troiano Acquaviva d'Aragona (1740-1755). Costanzi bekleidete daneben im Laufe der Jahre einige der bedeutendsten Kapellmeisterstellen Roms, insbesondere ab 1755 die der Cappella Giulia an S. Pietro. Zu seinen Schülern auf dem Violoncello zählte möglicherweise auch Luigi Boccherini (1743-1805). Costanzi starb 1778 im Alter von 73 Jahren hochgeschätzt in Rom. Das vorliegende Duett ist im Répertoire International des Sources Musicales (RISM) lediglich in der Musiksammlung Nordkirchen nachgewiesen; auf welchen Wegen dieses Werk von Italien ins Münsterland gelangte, ist unklar. Aufgrund des galanten Charakters dürfte dieses Duett in den späteren Lebensjahren Costanzis entstanden sein.

description: Oceanic oil-degrading bacteria produce copious amounts of exopolymeric substances (EPS) that facilitate their access to oil. The fate of EPS in the water column is in part determined by activities of heterotrophic microbes capable of utilizing EPS compounds as carbon and energy sources. To evaluate the potential of natural microbial communities to degrade EPS produced during oil degradation, we measured potential hydrolysis rates of six structurally distinct polysaccharides in two roller bottle experiments, using water from a natural oil seep in the northern Gulf of Mexico. The suite of polysaccharides used to measure the initial step in carbon degradation is indicative of polymers within microbial EPS. The treatments included (i) unamended surface or deep waters (whole water), and water amended with (ii) a water-accommodated fraction of oil (WAF), (iii) oil dispersant Corexit 9500, and (iv) WAF chemically-enhanced with Corexit (CEWAF). The oil and Corexit treatments were employed to simulate conditions during the Deepwater Horizon oil spill. Polysaccharide hydrolysis rates in the surface-water treatments were lowest in the WAF treatment, despite elevated levels of EPS in the form of transparent exopolymer particles (TEP). In contrast, the three deep-water treatments (WAF, Corexit, CEWAF) showed enhanced hydrolysis rates and TEP levels (WAF) compared to the whole water. We also observed variations in the spectrum of polysaccharide-hydrolyzing enzyme activities among the treatments. These substrate specificities were likely driven by activities of oil-degrading bacteria, shaping the pool of EPS and TEP as well as degradation products of hydrocarbons and Corexit compounds. A model calculation of potential turnover rates of organic carbon within the TEP pool suggests extended residence times of TEP in oil-contaminated waters, making them prone to serve as the sticky matrix for oily aggregates known as marine oil snow.

description: Heterotrophic microbial communities play key roles in processing and remineralizing organic matter in marine sediments: they are the “final gatekeepers” that determine the types and quantity of organicmatter that is ultimately buried in sediments—processes important to our understanding of past global environments, as well as to the production of petroleum products that still fuel much of modern society. These communities’ capabilities also help us understand the energetic and metabolic boundaries of life. Work over the past decades has revealed much information about sedimentary microbial communities: their overall composition (Bacteria and Archaea), the sequence of terminal respiration processes occurring with progressive burial depth in sediments, and the depth to which they can be detected; research on the members and metabolism in the “deep biosphere” has assumed a central position in organic geochemistry, environmental microbiology, and molecular ecology (Orcutt et al., 2013; D’Hondt et al., 2019).

description: Warm core, anticyclonic rings that spin off from the Gulf Stream circulate through the region directly offshore of the Mid-Atlantic Bight. If a warm core ring reaches the continental shelf break, its warm, highly saline water may subduct under cooler, fresher continental shelf surface water, resulting in subsurface waters at the shelf break and over the upper continental slope with high temperatures and salinities and distinct physical and chemical properties characteristic of Gulf Stream water. Such intruding water may also have microbial communities with distinct functional capacities, which may in turn affect the rate and nature of carbon cycling in this coastal/shelf environment. However, the functional capabilities of microbial communities within ring intrusion waters relative to surrounding continental shelf waters are largely unexplored. We investigated microbial community capacity to initiate organic matter remineralization by measuring hydrolysis of a suite of polysaccharide, peptide, and glucose substrates along a transect oriented across the Mid-Atlantic Bight shelf, shelf break, and upper slope. At the outermost sampling site, warm and salty water derived from a Gulf Stream warm core ring was present in the lower portion of the water column. This water exhibited hydrolytic capacities distinct from other sampling sites, and exhibited lower heterotrophic bacterial productivity overall. Warm core rings adjacent to the Mid-Atlantic Bight shelf have increased in frequency and duration in recent years. As the influence of warm core rings on the continental shelf and slope increases in the future, the rate and nature of organic matter remineralization on the continental shelf may also shift.

description: Der 1727 in Rudolstadt geborene Friedrich Hartmann Graf erhielt seinen ersten Unterricht auf der Traversflöte sowie in Komposition bei seinem Vater. Zunächst diente Graf als Militärmusiker in einem holländischen Regiment; ab 1759 schlug er die Laufbahn als Flötist ein. Bis 1766 lebte Graf in Hamburg, wo er organisatorisch wie auch künstlerisch öffentliche Subskriptionskonzerte leitete. Eine anschließende mehrjährige Konzertreise führte ihn als Flötenvirtuosen durch ganz Europa, bevor er in den Dienst des Grafen Karl von Bentheim-Steinfurt (1729-1780) und der von Johann Friedrich Klöffler (1725-1790) geleiteten Burgsteinfurter Hofkapelle trat. Bereits 1769 zog es Graf jedoch weiter nach Den Haag und schließlich 1773 als Musikdirektor der evangelischen Kirchen und des Gymnasiums St. Anna nach Augsburg. 1783/84 wurde Graf nach London berufen, um dort als Nachfolger Johann Christian Bachs (1735-1782) die "Professional Concerts" zu leiten; danach kehrte er jedoch in seine bisherige Stellung nach Augsburg zurück, wo er 1795 starb. In der Fürst zu Bentheimschen Musikaliensammlung Burgsteinfurt sind gut 30 Werke Grafs, insbesondere Flötenkonzerte und -quartette überliefert.

description: Space dimensionality is a crucial variable in the analysis of the structure and dynamics of natural systems and phenomena. The dimensionality effects of the blackbody radiation has been the subject of considerable research activity in recent years. These studies are still somewhat fragmentary, pos- ing formidable qualitative and quantitative problems for various scientific and technological areas. In this work we carry out an information-theoretical analysis of the spectral energy density of a d-dimensional blackbody at temperature T by means of various entropy-like quantities (disequilibrium, Shannon entropy, Fisher information) as well as by three (dimensionless) complexity measures (Crámer-Rao, Fisher-Shannon and LMC). All these frequency-functional quantities are calculated and discussed in terms of temperature and dimensionality. It is shown that all three measures of complexity have an universal character in the sense that they depend neither on temperature nor on the Planck and Boltzmann constants, but only on the the space dimensionality d. Moreover, they decrease when d is increasing; in particular, the values 2.28415, 1.90979 and 1.17685 are found for the Crámer-Rao, Fisher-Shannon and LMC measures of complexity of the 3-dimensional blackbody radiation, respectively. In addition, beyond the frequency at which the spectral density is maximum (which follows the well-known Wien displacement law), three further characteristic frequencies are defined in terms of the previous entropy quantities; they are shown to obey Wien-like laws. The potential usefulness of these distinctive features of the blackbody spectrum is physically discussed.

description: Microbes in the intestines of mammals degrade dietary glycans for energy and growth. The pathways required for polysaccharide utilization are functionally diverse; moreover, they are unequally dispersed between bacterial genomes. Hence, assigning metabolic phenotypes to genotypes remains a challenge in microbiome research. Here we demonstrate that glycan uptake in gut bacteria can be visualized with fluorescent glycan conjugates (FGCs) using epifluorescence microscopy. Yeast α-mannan and rhamnogalacturonan-II, two structurally distinct glycans from the cell walls of yeast and plants, respectively, were fluorescently labeled and fed to Bacteroides thetaiotaomicron VPI-5482. Wild-type cells rapidly consumed the FGCs and became fluorescent; whereas, strains that had deleted pathways for glycan degradation and transport were non-fluorescent. Uptake of FGCs, therefore, is direct evidence of genetic function and provides a direct method to assess specific glycan metabolism in intestinal bacteria at the single cell level.

de-RSE

description: In February 2023, the German RSE community came together at the deRSE23 conference in Paderborn in-person, for the first time since the global coronavirus pandemic. While this conference may represent the most visible marker of RSE activity in Germany, there are many more activities that show the progress that the German community has made over the last few years. This includes new developments in funding guidelines and policy, community building and infrastructures, collaborations, projects and research topics. In this talk, we will provide an update on the current status of research software in Germany and some of the most interesting developments, not only to share our successes, but also to identify remaining challenges and initiate further knowledge exchange across borders. The talk is informed by relevant initiatives in Germany, such as the German Society for Research Software - de-RSE, as well as their collaboration with other professional societies. It features developments and RSE activities from the Helmholtz Association of German Research Centers and universities, as well as the German National Research Data Infrastructure (NFDI), and further relevant initiatives. We will furthermore look at topics emerging in Germany with regard to research on research software itself. The talk finally focuses on the development of the RSE community in Germany itself, and serves as invitation to take part in upcoming activities, such as the second Germany-wide RSE event in 2023: the de-RSE unconference.

The main result of our research is the construction of a continuous curve in $(α,β)$ plane, which becomes a threshold between the existence and non-existence of positive solutions. Furthermore, we provide the example of domains $Ω$ for which the corresponding first Dirichlet eigenvalue of $-Δ_p$ is not monotone w.r.t. $p > 1$.

description: Introduction: The Amazon forest has been suffering from deforestation for decades caused by human action. Through this action, one can see the changes that have been taking place as global warming influences the climate changes that have occurred in Brazil and in the world. Objective: The objective of this work presents effective and
 feasible proposals for the problem of the degradation of the Amazon forest. Materials and Methods: This is an integrative review drawn from scientific articles, journals, documents and material made available in full by online virtual libraries. The following databases were consulted: Scielo, RT Online, CAPES, vLex and Pepsic, from 1947 to 2020, in Portuguese. Discussion and Results: The environmental issue of the degradation of the Amazon forest and its disastrous consequences is directly linked and will be equated, at least satisfactorily, to the correct direction of livestock activities, through the reduction of beef consumption levels and adoption of the intensive model of creation, as well as incentive to fish farming; agricultural, through the implementation of technological resources, in addition to reducing bureaucracy; of land tenure regularization. With the adoption, albeit partial, of the above measures, a significant improvement will be noted in the entire situation now verifiable of increasing degradation in the Amazon biome. Conclusion: It seems clear, through the analysis of the different processes that involve the region, that the different programs, the countless actions and the main instruments used by the government are not able to reduce deforestation. Thus, this work has as main objective to present several feasible proposals for the sustainable development of the Amazon.

description: An unidentified red bacterium strains isolated as endophyte of root nodule of faba bean, when characterized for morphological, microscopic, biochemical and molecular (16SrDNA sequence) features were identified as a novel strain of Serratia marcescens. The strain formed small red colony size measuring 2-3mm in diameter on Glucose Mannitol Tryptone Yeast Extract (GMTYE) agar medium. Under scanning electron microscopy, the single cell rods measured 3.55 - 4.18µm x 0.48µm - 0.68µm. The bacterium strain could efficiently utilize a wide range of carbohydrates (monosaccharide, disaccharide and polysaccharide) both for growth and pigmentation. It’s preferred simple form of organic nitrogen for growth and pigmentation but was unable to utilize inorganic sources of nitrogen. The bacterium could grow over a wide range of medium pH (4.00-11.00) and temperature (20-37°C) and NaCl concentration (0.5-2.0%) but optimal growth and pigmentation were observed in the GMTYE medium of pH (6.00-7.00) containing NaCl at 0.5 percent level and at 28°C of incubation temperature.
Selfish, sharing and scavenging bacteria in the Atlantic Ocean: a biogeographical study of bacterial substrate utilisation

description: Identifying the roles played by individual heterotrophic bacteria in the degradation of high molecular weight (HMW) substrates is critical to understanding the constraints on carbon cycling in the ocean. At five sites in the Atlantic Ocean, we investigated the processing of organic matter by tracking changes in microbial community composition as HMW polysaccharides were enzymatically hydrolysed over time. During this investigation, we discovered that a considerable fraction of heterotrophic bacteria uses a newly-identified ‘selfish’ mode of substrate processing. We therefore additionally examined the balance of individual substrate utilisation mechanisms at different locations by linking individual microorganisms to distinct substrate utilisation mechanisms. Through FISH and uptake of fluorescently-labelled polysaccharides, ‘selfish’ organisms were identified as belonging to the Bacteroidetes, Planctomycetes and Gammaproteobacteria. ‘Sharing’ (extracellular enzyme producing) and ‘scavenging’ (non-enzyme producing) organisms predominantly belonged to the Alteromonadaceae and SAR11 clades, respectively. The extent to which individual mechanisms prevail depended on the initial population structure of the bacterial community at a given location and time, as well as the growth rate of specific bacteria. Furthermore, the same substrate was processed in different ways by different members of a pelagic microbial community, pointing to significant follow-on effects for carbon cycling.
How many queries are needed to distinguish a truncated random permutation from a random function?

description: An oracle chooses a function $f$ from the set of $n$ bits strings to itself, which is either a randomly chosen permutation or a randomly chosen function. When queried by an $n$-bit string $w$, the oracle computes $f(w)$, truncates the $m$ last bits, and returns only the first $n-m$ bits of $f(w)$. How many queries does a querying adversary need to submit in order to distinguish the truncated permutation from the (truncated) function? In 1998, Hall et al. showed an algorithm for determining (with high probability) whether or not $f$ is a permutation, using $O(2^{\frac{m+n}{2}})$ queries. They also showed that if $m < n/7$, a smaller number of queries will not suffice. For $m > n/7$, their method gives a weaker bound. In this note, we first show how a modification of the approximation method used by Hall et al. can solve the problem completely. It extends the result to practically any $m$, showing that $Ω(2^{\frac{m+n}{2}})$ queries are needed to get a non-negligible distinguishing advantage. However, more surprisingly, a better bound for the distinguishing advantage can be obtained from a result of Stam published, in a different context, already in 1978. We also show that, at least in some cases, Stam's bound is tight.

description: The extent to which differences in microbial community structure result in variations in organic matter (OM) degradation is not well understood. Here, we tested the hypothesis that distinct marine microbial communities from North Atlantic surface and bottom waters would exhibit varying compositional succession and functional shifts in response to the same pool of complex high molecular weight (HMW-OM). We also hypothesized that microbial communities would produce a broader spectrum of enzymes upon exposure to HMW-OM, indicating a greater potential to degrade these compounds than reflected by initial enzymatic activities. Our results show that community succession in amended mesocosms was congruent with cell growth, increased bacterial production and most notably, with substantial shifts in enzymatic activities. In all amended mesocosms, closely related taxa that were initially rare became dominant at time frames during which a broader spectrum of active enzymes were detected compared to initial timepoints, indicating a similar response among different communities. However, succession on the whole-community level, and the rates, spectra and progression of enzymatic activities, reveal robust differences among distinct communities from discrete water masses. These results underscore the crucial role of rare bacterial taxa in ocean carbon cycling and the importance of bacterial community structure for HMW-OM degradation.

description: The problem of directivity enhancement, leading to the increase in the directivity gain over a certain desired angle of arrival/departure (AoA/AoD), is considered in this work. A new formulation of the volumetric array directivity problem is proposed using the rectangular coordinates to describe each antenna element and the desired azimuth and elevation angles with a general element pattern. Such a directivity problem is formulated to find the optimal minimum distance between the antenna elements $d_\text{min}$ aiming to achieve as high directivity gains as possible. {An expedited implementation method is developed to place the antenna elements in a distinctive plane dependent on ($θ_0$; $ϕ_0$). A novel concept on optimizing directivity for the uniform planar array (OUPA) is introduced to find a quasi-optimal solution for the non-convex optimization problem with low complexity. This solution is reached by deploying the proposed successive evaluation and validation (SEV) method. {Moreover, the genetic} algorithm (GA) method was deployed to find the directivity optimization solution expeditiously. For a small number of antenna elements {, typically $N\in [4,\dots, 9]$,} the achievable directivity by GA optimization demonstrates gains of $\sim 3$ dBi compared with the traditional beamforming technique, using steering vector for uniform linear arrays (ULA) and uniform circular arrays (UCA), while gains of $\sim1.5$ dBi are attained when compared with an improved UCA directivity method. For a larger number of antenna elements {, two improved GA procedures, namely GA-{\it marginal} and GA-{\it stall}, were} proposed and compared with the OUPA method. OUPA also indicates promising directivity gains surpassing $30$ dBi for massive MIMO scenarios.

description: Stars close to the Eddington luminosity can have large low-density inflated envelopes. We show that the rise times of shock breakout signals from supernovae can be extended significantly if supernova progenitors have an inflated stellar envelope. If the shock breakout occurs in such inflated envelopes, the shock breakout signals diffuse in them, and their rise time can be significantly extended. Then, the rise times of the shock breakout signals are dominated by the diffusion time in the inflated envelope rather than the light-crossing time of the progenitors. We show that our inflated Wolf-Rayet star models whose radii are of the order of the solar radius can have shock breakout signals which are longer than ~100 sec. The existence of inflated envelopes in Wolf-Rayet supernova progenitors may be related to the mysterious long shock breakout signal observed in Type Ib SN 2008D. Extended shock breakout signals may provide evidence for the existence of inflated stellar envelopes and can be used to constrain the physical properties of these enigmatic structures.

MetaSeek is a sequencing data discovery tool that enables users to flexibly search and filter on any metadata field to quickly find the sequencing datasets that meet their needs. MetaSeek automatically scrapes metadata from all publicly available datasets in the Sequence Read Archive, cleans and parses messy, user-provided metadata into a structured, standard-compliant database and predicts missing fields where possible. MetaSeek provides a web-based graphical user interface and interactive visualization dashboard, as well as a programmatic API to rapidly search, filter, visualize, save, share and download matching sequencing metadata.

Energy conversion efficiency from a high order soliton to fundamental solitons in presence of Raman scattering

description: We formulate the energy conversion efficiency from a high-order soliton to fundamental solitons by including the influence of interpulse Raman scattering in the fission process. The proposed analytical formula agrees closely with numerical results of the generalized nonlinear Schrodinger equation as well as to experimental results, while the resulting formulation significantly alters the energy conversion efficiency predicted by the Raman-independent inverse scattering method. We also calculate the energy conversion efficiency in materials of different Raman gain profiles such as silica, ZBLAN and chalcogenide glasses (As2S3 and As2Se3). It is predicted that ZBLAN glass leads to the largest energy conversion efficiency of all four materials. The energy conversion efficiency is a notion of utmost practical interest for the design of wavelength converters and supercontinuum generation systems based on the dynamics of soliton self-frequency shift.

description: The geometrical shapes and the physical properties of stellar wind -- interstellar medium interaction regions form an important stage for studying stellar winds and their embedded magnetic fields as well as cosmic ray modulation. Our goal is to provide a proper representation and classification of counter-flow configurations and counter-flow interfaces in the frame of fluid theory. In addition we calculate flows and large-scale electromagnetic fields based on which the large-scale dynamics and its role as possible background for particle acceleration, e.g. in the form of anomalous cosmic rays, can be studied. We find that for the definition of the boundaries, which are determining the astropause shape, the number and location of magnetic null points and stagnation points is essential. Multiple separatrices can exist, forming a highly complex environment for the interstellar and stellar plasma. Furthermore, the formation of extended tail structures occur naturally, and their stretched field and streamlines provide surroundings and mechanisms for the acceleration of particles by field-aligned electric fields.

Structure and function of high Arctic pelagic, particle-associated and benthic bacterial communities

description: Arctic marine microbes are affected by environmental changes that may ultimately influence their functions in carbon cycling. Here, we investigated in concert the structure and enzymatic activities of pelagic, particle-associated and benthic bacterial communities in the central Arctic Ocean, and used these data to evaluate microbial structure–function relationships. Our findings showed influences of hydrographic conditions and particle association on community composition, and sharp pelagic-benthic contrasts. In addition to community compositional differences, regional and depth-related patterns in enzymatic activities were observed. Peptide hydrolysis rates were highest in surface waters, especially at ice-free and first year ice-covered regions, and decreased with depth. While the range of hydrolysed polysaccharides showed varying geographic patterns, particles often showed a wider spectrum of polysaccharide hydrolase activities. Summed benthic peptidase rates differed across stations but showed similar proportions of individual enzyme activities. Analysing for potential linkages between structure and function after subtracting the effect of environmental conditions revealed no direct link, indicating functional redundancy to carry out peptide hydrolysis among pelagic microbes. Thus, while community composition and activities are influenced by environmental conditions, bacterial functional redundancy suggests that compositional shifts – in response to the changing Arctic – may have complex and less predictable functional consequences than previously anticipated.

description: We propose a novel, Gaussian signaling mechanism for low probability of detection (LPD) communication systems with either single or multiple antennas. The new scheme is designed to allow the noncoherent detection of Gaussian-distributed signals, enabling LPD communications using signals that follow the complex Gaussian distribution in the time and frequency domains. It is demonstrated via simulations that the proposed scheme achieves better performance than a comparable conventional scheme over the entire SNR region, with the advantage becoming more significant in scenarios with lower overhead.

Octonionic Gravi-electromagnetism and Dark Matter

description: An attempt has been made to analyse the the role of octonions in various unified field theories associated with dyons and the dark matter. Starting with the split octonion al- gebra and its properties, we have discussed the octonionic unified gauge formulation for SU(2) ?X U(1) electroweak theory and SU(3) X? SU(2) ?X U(1) grand unified theory. De- scribing the octonion eight dimensional space as the combination of two quaternionic spaces (namely associated with the electromagnetic interaction (EM-space) and linear gravitational interaction (G-space)), we have reexamined the unified picture of EM-G space in terms of oc- tonionic split formulation in consistent manner. Consequently, we have obtained the various field equations for unified gravi-electromagnetic interactions. Furthermore, we have recon- structed the field equations of hot and cold dark matter in terms of split octonions. It is shown that the difference between the octonion cold dark matter (OCDM) and the octonion hot dark matter (OHDM) is significant in the formulating of structure of these two, because the velocities of octonion hot dark matter cause it to wipe out structure on small scales.
