description: We present an unprecedented view on the morphology and kinematics of the extended narrow-line region (ENLR) and molecular gas around the prototypical hyper-luminous quasar 3C273 ($L\sim10^{47}$ erg/s at z=0.158) based on VLT-MUSE optical 3D spectroscopy and ALMA observations. We find that: 1) The ENLR size of 12.1$\pm$0.2kpc implies a smooth continuation of the size-luminosity relation out to large radii or a much larger break radius as previously proposed. 2) The kinematically disturbed ionized gas with line splits reaching 1000km/s out to 6.1$\pm$1.5kpc is aligned along the jet axis. 3) The extreme line broadening on kpc scales is caused by spatial and spectral blending of many distinct gas clouds separated on sub-arcsecond scales with different line-of-sight velocities. The ENLR velocity field combined with the known jet orientation rule out a simple scenario of a radiatively-driven radial expansion of the outflow. Instead we propose that a pressurized expanding hot gas cocoon created by the radio jet is impacting on an inclined gas disk leading to transverse and/or backflow motion with respect to our line-of-sight. The molecular gas morphology may either be explained by a density wave at the front of the outflow expanding along the jet direction as predicted by positive feedback scenario or the cold gas may be trapped in a stellar over-density caused by a recent merger event. Using 3C273 as a template for observations of high-redshift hyper-luminous AGN reveals that large-scale ENLRs and kpc scale outflows may often be missed due to the brightness of the nuclei and the limited sensitivity of current near-IR instrumentation.

description: We study three transient X-ray sources, that were bright in the central region of M31 galaxy in the year 2000. Observations with Chandra and XMM-Newton allowed us for the first time in the history of X-ray astronomy, to build light curves of transient sources in M31 suitable for studying their variability on a time scale of months and, in some periods, weeks. The three sources demonstrate distinctly different types of X-ray variability and spectral evolution. XMMU J004234.1+411808 is most likely a black hole candidate based on the similarity of its X-ray light curve and spectra to typical transient low-mass X-ray binaries observed in our Galaxy. The outburst of CXO J004242.0+411608 lasted longer than a year, which makes the source an unusual X-ray transient. The supersoft transient XMMU J004319.4+ 411759 is probably a classical nova-like system containing a magnetized, rapidly-spinning white dwarf. We estimate a total rate of X-ray transient outbursts in the central bulge of M31 to be of the order ~10 per year. The rate of the hard X-ray transients (~5 1/year) in the central part of the Andromeda Galaxy appears to be comparable to that of the central part of our own Galaxy.

description: Diese Untersuchung fokussiert auf die Herausforderungen, die sich bei der Verarbeitung von Klimadaten durch Simulationssoftware ergeben.Ein zentraler Aspekt besteht darin, die unterschiedlichen Definitionen von Ort und Zeit zu berücksichtigen, wenn Testreferenzjahre (TRY) verschiedener Datenreihen verwendet werden. Dabei werden die Definitionen und Angaben der Zeiten miteinander verglichen und bewertet. Die Untersuchung erfolgt exemplarisch für die TRY des Deutschen Wetterdienstes (DWD), ist jedoch auch für andere Klimadatengeber gültig. Es wird dargestellt, wie diese Zeitdefinitionen die Umrechnung von direkter und diffuser Strahlung beeinflussen und aufgezeigt, dass für simulative Berechnungen präzise und eindeutige Zeiten für bestimmte Orte unerlässlich sind, um insbesondere bei Sonnenaufgang und untergang unrealistische Abweichungen zu vermeiden. In diesem Kontext werden die Definitionen in den DWD-Testreferenzjahren 2010, 2015 und 2045 beleuchtet. Es wird ersichtlich, dass die Definitionen teilweise sogar innerhalb derselben Datensätze inkonsistent sind. Zudem wird erörtert, dass verschiedene Simulationssoftwares unterschiedlich mit diesen Definitionen umgehen.Abschließend betont die Analyse die Notwendigkeit einer genauen Übereinstimmung zwischen dem Standort des Gebäudes und dem Standort des Klimadatensatzes sowie die Bedeutung einer einheitlichen Zeitdefinition über verschiedene TRY-Datenreihen hinweg. Eine präzise Erfassung der Strahlungsdaten zu einem bestimmten Zeitpunkt ist für korrekte Anwendungen unerlässlich und ermöglicht die genaue Aufteilung der Strahlungswerte zwischen Vormittag (Osten) und Nachmittag (Westen).

description: The advancement of Uzbekistan’s healthcare system necessitates a comprehensive approach to digitalization and the establishment of favorable conditions for the population. However, as the observations show that implementing digital marketing technologies within Uzbekistan's healthcare system faces several challenges. For example, many healthcare facilities lack the necessary digital infrastructure, hindering the effective deployment of digital marketing strategies, strict regulations on medical advertising and patient data privacy limit the scope of digital marketing initiatives.

description: Background: Urine cultures are usually obtained from 0- to 2-month-old febrile infants, while in older children they are obtained more selectively. In 3- to 23-month-old children, urinary tract infection (UTI) diagnosis requires both positive culture and dipstick, but data are scarce regarding 0- to 2-month-old infants. We assessed dipstick performance for UTI diagnosis in 0–2 vs. 3- to 23-month-old children. Methods: A case–control study, conducted between 2015 and 2016, in southern Israel. Sensitivity and specificity of urine dipstick for diagnosing UTI were assessed. We compared dipstick false-negative (FN) and true-positive (TP) groups; high FN rate indicates low sensitivity. Results: Overall, 434 positive and 571 sterile urine culture episodes were included. Dipstick sensitivity was 63% in 0-2 month old children; 93% for supra-pubic aspiration (SPA), and ∼50% for non-SPA sampling method. However, sensitivity was >90% for 3–5 and 6- to 23-month-old children. In univariate analysis, younger age, hospitalization, lower temperature, short fever duration, lower leukocyte blood levels, neutrophils, stabs and C-reactive protein, and absent future UTI within <1 year were associated with FN compared with TP. In multivariate analysis, among positive culture episodes, age 0–2 months (odds ratio, OR = 6.60) and non-SPA sampling method (OR = 8.39) were associated with FN episodes. Conclusions: Dipstick lower sensitivity for diagnosing UTI in febrile infants 0–2 months old vs. their older counterparts, was associated with non-SPA sampling method, lower inflammatory markers, lower temperature and low risk for future UTI. This suggests that positive culture in negative dipstick episodes may not reflect a true UTI.

description: The Micro Air Vehicle Link (MAVLink in short) is a communication protocol for unmanned systems (e.g., drones, robots). It specifies a comprehensive set of messages exchanged between unmanned systems and ground stations. This protocol is used in major autopilot systems, mainly ArduPilot and PX4, and provides powerful features not only for monitoring and controlling unmanned systems missions but also for their integration into the Internet. However, there is no technical survey and/or tutorial in the literature that presents these features or explains how to make use of them. Most of the references are online tutorials and basic technical reports, and none of them presents comprehensive and systematic coverage of the protocol. In this paper, we address this gap, and we propose an overview of the MAVLink protocol, the difference between its versions, and its potential in enabling Internet connectivity to unmanned systems. We also discuss the security aspects of MAVLink. To the best of our knowledge, this is the first technical survey and tutorial on the MAVLink protocol, which represents an important reference for unmanned systems users and developers.

description: The secure operation of future power systems will rely on better coordination between transmission system and distribution system operators. Increasing integration of renewables throughout the whole system is challenging the traditional operation. To tackle this problem, the SmartNet project proposes and evaluates five different coordination schemes between system operators using three benchmark scenarios from Denmark, Italy, and Spain. In the project, field tests in each of the benchmark countries are complemented with a number of laboratory validation tests, to cover scenarios that cannot be tested in field trials. This paper presents the outcome of these laboratory tests. Three tests are shown, focusing on controller validation, analysis of communication impacts, and how well price-based controls can integrate with the SmartNet coordination schemes. The results demonstrate important indications for the field tests and also show some of the limitations with the current implementations of the coordinations schemes.

description: We propose a generalized Dicke model which supports a quantum tricritical point. We map out the phase diagram and investigate the critical behaviors of the model through exact low-energy effective Hamiltonian in the thermodynamic limit. As predicted by the Landau theory of phase transition, the order parameter shows non-universality at the tricritical point. Nevertheless, as a result of the separation of the classical and the quantum degrees of freedom, we find a universal relation between the excitation gap and the entanglement entropy for the entire critical line including the tricritical point. Here the universality is carried by the emergent quantum modes, whereas the order parameter is determined classically.

description: We introduce a new shrinkage prior on function spaces, called the functional horseshoe prior (fHS), that encourages shrinkage towards parametric classes of functions. Unlike other shrinkage priors for parametric models, the fHS shrinkage acts on the shape of the function rather than inducing sparsity on model parameters. We study the efficacy of the proposed approach by showing an adaptive posterior concentration property on the function. We also demonstrate consistency of the model selection procedure that thresholds the shrinkage parameter of the functional horseshoe prior. We apply the fHS prior to nonparametric additive models and compare its performance with procedures based on the standard horseshoe prior and several penalized likelihood approaches. We find that the new procedure achieves smaller estimation error and more accurate model selection than other procedures in several simulated and real examples. The supplementary material for this article, which contains additional simulated and real data examples, MCMC diagnostics, and proofs of the theoretical results, is available online.

description: The Very Energetic Radiation Imaging Telescope Array System (VERITAS) represents an important step forward in the study of extreme astrophysical processes in the universe. It combines the power of the atmospheric Cherenkov imaging technique using a large optical reflector with the power of stereoscopic observatories using arrays of separated telescopes looking at the same shower. The seven identical telescopes in VERITAS, each of aperture 10 m, will be deployed in a filled hexagonal pattern of side 80 m; each telescope will have a camera consisting of 499 pixels with a field of view of 3.5 deg VERITAS will substantially increase the catalog of very high energy (E > 100GeV) gamma-ray sources and greatly improve measurements of established sources.

A new strategy to microscopic modelling of topological entanglement in polymers based on field theory

description: In this work a new strategy is proposed in order to build analytic and microscopic models of fluctuating polymer rings subjected to topological constraints. The topological invariants used to fix these constraints belong to a wide class of the so-called numerical topological invariants. For each invariant it is possible to derive a field theory that describes the statistical behavior of knotted and linked polymer rings following a straightforward algorithm. The treatment is not limited to the partition function of the system, but it allows also to express the expectation values of general observables as field theory amplitudes. Our strategy is illustrated taking as examples the Gauss linking number and a topological invariant belonging to a class of invariants due to Massey. The consistency of the new method developed here is checked by reproducing a previous field theoretical model of two linked polymer rings. After the passage to field theory, the original topological constraints imposed on the fluctuating paths of the polymers become constraints over the configurations of the topological fields that mediate the interactions of topological origin between the monomers. These constraints involve quantities like the cross-helicity which are of interest in other disciplines, like for instance in modeling the solar magnetic field. While the calculation of the vacuum expectation values of generic observables remains still challenging due to the complexity of the problem of topological entanglement in polymer systems, we succeed here to reduce the evaluation of the moments of the Gauss linking number for two linked polymer rings to the computation of the amplitudes of a free field theory.

description: Novel chromenyl α-aminophosphonic acid 4 and dialkyl chromenyl phosphonate 6 have been obtained. In addition, some novel types of chromene fused with phosphorus heterocycles such as chromeno[4,3-c][1,2]azaphospholes 5 and 7, chromeno[2,3-d][1,3,2]diazaphosphinine 8 and 1,2-oxaphosphinino[3,4-c]pyridine 10 have been synthesized. The methodology depended on treatment of 2-imino-2H-chromene-3-carboxamide (1) with some phosphorus esters. The synthesized compounds were evaluated for antioxidant and cytotoxic activities. Among the synthesized compounds, compound 5 exhibited the most antioxidant activity with IC50 = 2.8 μg/mL in comparison with ascorbic acid as standard antioxidant. Also, compound 5 had significant cytotoxic effects against four cancer cell lines. Its IC50 values ranged between 4.96 and 7.44 μg/mL in comparison to doxorubicin (IC50 = 0.426–0.493 μg/mL).

description: Variational Autoencoders (VAEs) have become a cornerstone in generative modeling, providing a powerful framework for learning latent representations of data. Recent advances in neural architectures, such as EfficientNet, offer promising avenues for improving VAE performance while reducing resource consumption. This paper aims to explore the integration of these advancements to enhance transfer learning in VAEs for mobile and resourceconstrained environments. The proposed model integrates the Adam optimizer with Amortized Stochastic Variationsal Inference (ASVI), adaptive hyperparameter tuning, and specific miniaturization techniques. The ELBO is optimised to maximise the predicted log-likelihood while minimising the KL divergence between the variational posterior and the prior over latent variables. We evaluate our proposed model on three benchmark datasets: MNIST, CIFAR-10, and CelebA. Our experimental results demonstrate significant performance gains in terms of reconstruction quality, classification accuracy, and computational efficiency. Our proposed model sets a new benchmark for transfer learning, paving the way for further research in this direction

description: Millions of people in the world perform welding as their primary occupation resulting in exposure to metal-containing nanoparticles in the fumes generated. Even though health effects including airway diseases are well-known, there is currently a lack of studies investigating how different welding set-ups and conditions affect the toxicity of generated nanoparticles of the welding fume. The aim of this study was to investigate the toxicity of nine types of welding fume particles generated via active gas shielded metal arc welding (GMAW) of chromium-containing stainless steel under different conditions and, furthermore, to correlate the toxicity to the particle characteristics. Toxicological endpoints investigated were generation of reactive oxygen species (ROS), cytotoxicity, genotoxicity and activation of ToxTracker reporter cell lines. The results clearly underline that the choice of filler material has a large influence on the toxic potential. Fume particles generated by welding with the tested flux-cored wire (FCW) were found to be more cytotoxic compared to particles generated by welding with solid wire or metal-cored wire (MCW). FCW fume particles were also the most potent in causing ROS and DNA damage and they furthermore activated reporters related to DNA double- strand breaks and p53 signaling. Interestingly, the FCW fume particles were the most soluble in PBS, releasing more chromium in the hexavalent form and manganese compared to the other fumes. These results emphasize the importance of solubility of different metal constituents of the fume particles, rather than the total metal content, for their acute toxic potential.

description: Inverse Compton (IC) scattering of nuclear photons with relativistic electrons in the lobes of powerful radio galaxies and quasars can give detectable extended X-ray emission from the radio lobes if relativistic electrons with a Lorentz factor gamma about 300 are present (Brunetti, Setti, Comastri 1997). In general these electrons are not detected since they emit synchrotron radiation at frequencies below the radio band, so that the study of this effect provides a unique tool to measure the energy distribution of the electron population in the radio lobes at gamma lower than 1000. In this paper we reanalyze the Chandra observation of the powerful and compact radio galaxy 3C 295 for which the IC scattering of nuclear photons is expected to be an important mechanism. We find strong evidence for extended and asymmetrical X-ray emission associated with the radio lobes in the energy band 0.1--2 keV. We show that both the luminosity and morphology of the extended X-ray emission associated with the radio lobes, not compatible with other X-ray mechanisms, can be best interpreted by the IC scattering with nuclear photons. We also show that the relativistic electron energy distribution obtained from the synchrotron radio emission can be extrapolated down to gamma about 100 thus providing a first direct evidence on the electron spectrum in the lobes down to lower energies.

description: We construct a class of global exact solutions of the Einstein equations that extend the Oppeheimer-Snyder (OS) model to the case of non-zero pressure, {\em inside the Black Hole}, by incorporating a shock wave at the leading edge of the expansion of the galaxies, arbitrarily far beyond the Hubble length in the Friedmann-Robertson-Walker (FRW) spacetime. Here the expanding FRW universe emerges behind a subluminous blast wave that explodes outward from the FRW center at the instant of the Big Bang. The total mass behind the shock decreases as the shock wave expands, and the entropy condition implies that the shock wave must weaken to the point where it settles down to an OS interface, (bounding a {\em finite} total mass), that eventually emerges from the White Hole event horizon of an ambient Schwarzschild spacetime. The entropy condition breaks the time symmetry of the Einstein equations, selecting the explosion over the implosion. These shock wave solutions indicate a new cosmological model in which the Big Bang arises from a localized explosion occurring inside the Black Hole of a Schwarzschild spacetime.

description: In recent years, it has become easy to obtain location information quite precisely. However, the acquisition of such information has risks such as individual identification and leakage of sensitive information, so it is necessary to protect the privacy of location information. For this purpose, people should know their location privacy preferences, that is, whether or not he/she can release location information at each place and time. However, it is not easy for each user to make such decisions and it is troublesome to set the privacy preference at each time. Therefore, we propose a method to recommend location privacy preferences for decision making. Comparing to existing method, our method can improve the accuracy of recommendation by using matrix factorization and preserve privacy strictly by local differential privacy, whereas the existing method does not achieve formal privacy guarantee. In addition, we found the best granularity of a location privacy preference, that is, how to express the information in location privacy protection. To evaluate and verify the utility of our method, we have integrated two existing datasets to create a rich information in term of user number. From the results of the evaluation using this dataset, we confirmed that our method can predict location privacy preferences accurately and that it provides a suitable method to define the location privacy preference.

description: We present new radial velocity (RV) measurements for 11 candidate young very-low-mass stars and brown dwarfs, with spectral types from M7 to L7. Candidate young objects were identified by features indicative of low surface gravity in their optical and/or near-infrared spectra. RV measurements are derived from high resolution (R=$λ$/$Δλ$=20,000) $J$ band spectra taken with NIRSPEC at the Keck Observatory. We combine RVs with proper motions and trigonometric distances to calculate three-dimensional space positions and motions and to evaluate membership probabilities for nearby young moving groups (NYMGs). We propose 2MASS J00452143+1634446 (L2$β$, $J$=13.06) as an RV standard given the precision and stability of measurements from three different studies. We test the precision and accuracy of our RV measurements as a function of spectral type of the comparison object, finding that RV results are essentially indistinguishable even with differences of $\pm$5 spectral subtypes. We also investigate the strengths of gravity-sensitive K~{\sc i} lines at 1.24--1.25 $μ$m and evaluate their consistency with other age indicators. We confirm or re-confirm four brown dwarf members of NYMGs -- 2MASS J00452143+1634446, WISE J00470038+6803543, 2MASS J01174748$-$3403258, and 2MASS J19355595$-$2846343 -- and their previous age estimates. We identify one new brown dwarf member of the Carina-Near moving group, 2MASS J21543454$-$1055308. The remaining objects do not appear to be members of any known NYMGs, despite their spectral signatures of youth. These results add to the growing number of very-low-mass objects exhibiting signatures of youth that lack likely membership in a known NYMG, thereby compounding the mystery regarding local, low-density star formation.

description: Deep learning techniques, namely convolutional neural networks (CNN), have previously been adapted to select gamma-ray events in the TAIGA experiment, having achieved a good quality of selection as compared with the conventional Hillas approach. Another important task for the TAIGA data analysis was also solved with CNN: gamma-ray energy estimation showed some improvement in comparison with the conventional method based on the Hillas analysis. Furthermore, our software was completely redeveloped for the graphics processing unit (GPU), which led to significantly faster calculations in both of these tasks. All the results have been obtained with the simulated data of TAIGA Monte Carlo software; their experimental confirmation is envisaged for the near future.

description: In printed electronics, conductive traces are often produced by printing inks of silver nanoparticles dispersed in solvents. A sintering process is usually needed to make the printed inks conductive by removing the organic dispersants and allowing metal-to-metal contacts among nanoparticles for atomic diffusion and neck formation. It has been challenging to sinter silver nanoparticle inks in a thermal oven at a temperature < 150 C to avoid thermal damage to the plastic substrate while achieving desired conductivity. This work presents a simple yet effective way to sinter a silver nanoparticle ink below 120 C (even at 80 C) by exposing the printed ink to water vapor in the oven. The results consistently show a significant reduction of line resistivity for the samples sintered in a moist oven compared to those sintered in a dry oven. Hence, solvent vapor-assisted sintering of metal nanoparticle inks can become an enabling approach to broaden product range of printed electronics.

 Karyology. Two of the three specimens showed a triploid karyotype, with 3 n 554 (®gure 5c), the third one being diploid (2 n 536).
 We have assigned these new species to the genus Nicodrilus BoucheÂ, 1972 instead of Allolobophora Eisen, 1874 or Aporrectodea O È rley, 1885 due to the fact that the ®rst is a genus with detailed diagnoses, based on the close phylogenetic relationship among the component species and, therefore, more natural from the evolutive point of view (BoucheÂ, 1972). On the contrary, the genera Allolobophora and Aporrectodea sensu lato have simple, clearly arti®cial diagnoses.

description: Analysis of Hubble Space Telescope/Wide Field Planetary Camera 2 images of Stephan's Quintet, Hickson Compact Group 92, yielded 115 candidate star clusters (with V-I < 1.5). Unlike in merger remants, the cluster candidates in Stephan's Quintet are not clustered in the inner regions of the galaxies; they are spread over the debris and surrounding area. Specifically, these sources are located in the long sweeping tail and spiral arms of NGC 7319, in the tidal debris of NGC 7318B/A, and in the intragroup starburst region north of these galaxies. Analysis of the colors of the clusters indicates several distinct epochs of star formation that appear to trace the complex history of dynamical interactions in this compact group.

description: Abstract

Micronutrient deficiencies are a significant public health concern, particularly among mothers of reproductive age and infants in developing regions. This study assesses the prevalence and impact of micronutrient deficiencies in Kismayo, Somalia, focusing on the nutritional status of mothers and infants at Kismayo General Hospital. The research identifies key micronutrient deficiencies, their causes, and the associated health risks.

Using a cross-sectional study design, data was collected through surveys, interviews, and laboratory tests conducted on mothers and infants. The findings indicate a high prevalence of deficiencies in iron, vitamin A, iodine, and folic acid, which contribute to anemia, poor immune function, and developmental delays. The study highlights critical factors such as inadequate dietary intake, food insecurity, and limited access to healthcare services as primary causes of micronutrient deficiencies.

The research underscores the need for comprehensive nutrition intervention programs, including micronutrient supplementation, public health awareness campaigns, and improved healthcare services. Recommendations include enhancing community-based nutrition education, integrating fortified foods into diets, and strengthening maternal and child health policies. This study provides valuable insights for policymakers, healthcare providers, and organizations working to combat micronutrient deficiencies in Somalia.
