Optical and near-infrared observations of the Fried Egg Nebula; Multiple shell ejections on a 100 yr timescale from a massive yellow hypergiant
Creators: name: Koumpia Evgenia
Publisher: name: Zenodo
Year: 2022

description: The fate of a massive star during the latest stages of its evolution is highly dependent on its mass-loss rate and geometry. The geometry of the mass-loss process can be inferred from the shape of the circumstellar material, having a significant influence on the evolution of massive stars (25 and 40 Msun), i.e., type II SN progenitors. In this context, yellow hypergiants (YHGs) offer an excellent opportunity to study mass-loss events. I present the analysis of a large set of optical and near-infrared data in spectroscopic, photometric, spectropolarimetric, and interferometric (GRAVITY/VLTI) modes, towards the IRAS 17163-3907 and its associated Fried Egg Nebula. This talk will cover the first reconstructed images of IRAS 17163−3907 around the 2-micron emission tracing milli-arcsecond scales, but also how our 2D radiative transfer modelling led to the discovery of a third hot inner shell with a maximum dynamical age of only 30 yr. We find three observed distinct mass-loss episodes which are characterised by different mass-loss rates and can inform theories of mass-loss mechanisms, which is a topic still under debate both in theory and observations.

description: We introduce a modified Jaynes-Cummings model with single-photon cavity radiation field but with the atomic system instead of exchanging a single photon as in the Jaynes-Cummings model, it exchanges instead a squeezed photon with squeezing parameter r. This allows us to interpolate between the Rabi model, r = infinity, and the Jaynes-Cummings model, r = 0, by varying r. The model exhibits a quantum phase transition. Accordingly, the quantum phase transition realized in the Rabi model, giving rise to superradiance, also occurs in the Jaynes-Cummings model

description: Hydrogen production through the processes of ethanol catalytic steam reforming (SR) is one of the promising routes due to its extensive yield that can be gained. However, catalyst deactivation (as a result of coke formation) is a major drawback in such a process. Therefore, this research work introduces efficient MgO supported Cubic cobalt oxide catalyst for the process of ethanol SR. This catalyst was successfully able to produce gases that have high contents of CO-free hydrogen was produced (above 78%) at 500°C and various flow rates of feed. This catalyst had also avoided coke formation at that temperature while attaining capture of the in-situ produced CO2 gas. The employment of an operating temperature beyond 500°C, during the SR process, could reduce the percentages of hydrogen (in products) to less than 55%. Such increases in the operational temperature could leave behind the detection of coke deposits onto the catalyst surface. The presence of these deposits was confirmed visually as well as via Raman spectroscopy.

description: Poor spatial targeting of agri-environmental measures (AEMs) is frequently criticised as a major cause for insufficient biodiversity conservation effectiveness. For the horizontal measure organic farming (OF), targeting of remuneration is considered to be necessary because conservation effectiveness might be higher in structurally complex landscapes with high amounts of biodiversity related landscape features. In this article, we investigate the spatial congruence between OF and biodiversity related landscape features at the NUTS 3-regional level (Nomenclature of Territorial Units for Statistics) in Germany. Using principal component analysis and generalised least square models, we tested the predictor variable value for proportions of permanent pastures, (semi-) natural habitats, Natura 2000 sites, protected habitats and forests as well as the number of the total and endangered plant species. We found OF to be more prevalent in regions with favourable landscape conditions for increasing biodiversity on farmland, i.e. regions with higher proportion of permanent pastures, (semi-) natural habitats and protected habitats. Our results suggest that, at present, conservation potentially benefits from the general funding of OF in Germany without spatial targeting as OF is already concentrated in structurally complex landscapes. Given the assumption that targeted AEMs cause additional administrative efforts, the efficiency of the general funding seems to be sufficient.

description: In this study, one-dimensional zinc (Zn)-doped cadmium sulphide (CdS) nanowires were synthesised by a solvothermal method. The Zn doping concentrations were varied from 1 to 5 mol% (ZnxCd1−xS where x = 0.001, 0.003 and 0.005). As-prepared materials were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy and UV–visible spectroscopy. Electrochemical impedance spectroscopy (EIS) was conducted to measure the charge transfer resistance. The photocatalytic performance of prepared materials was evaluated by the photodegradation of methylene blue (MB) dye. The result showed that 5% Zn-doped CdS is more photoactive as compared to other corresponding doped and undoped CdS. The increase in photocatalytic performance is due to improvement in the charge separation.

description: The trinuclear copper complex, [Cu3(μ3-OH)(CTMB)3(NO3)2(CH3CN)2]·5CH3CN·H2O (1) {CTMB = cyclohexotriazole-3-(4-methoxybenzamide)}, has been prepared by mixing Cu(NO3)2·2.5H2O and CHMBH {CHMBH = N,N′-cyclohexane-1,2-diylidene-bis(4-methoxybenzoylhydrazide)} in acetonitrile under ambient conditions. Compound 1 was characterized by IR and UV–visible spectroscopies as well as elemental analyses. X-ray crystallography shows that the cluster contains a {Cu3(μ3-OH)} core supported by three triazole-based Schiff base ligands. Each Cu is bound to the 2-N of one triazole ring and the 1-N of another. However, the coordination sphere of each Cu is different, one is five-coordinate and the other two are six-coordinate and bridged by a NO3 group. The six-coordinate sites are different, one has a terminal NO3 and the other a MeCN ligand. Magnetic measurements revealed the presence of isotropic and antisymmetric exchange between the copper(II) centers. The data were analyzed using the Hamiltonian containing isotropic exchange for an isosceles triangle together with antisymmetric exchange: H = –J1(S1S2 + S2S3)−J2S1S3 + G[S1 × S2 + S2 × S3 + S3 × S1]. Compound 1 exhibits strong antiferromagnetic coupling with J1 = −180 and J2 = −118 cm−1 and antisymmetric exchange with Gz = 15 cm−1. Stopped flow spectrophotometric studies show that the formation of 1 occurs in three distinct phases and the kinetics of each phase has been determined.

description: LED lamps already conquered the market of general lighting and are expected to generate a substantial stream of e-waste in the coming years. The challenge of recycling LED lamps have emerged, and it is essential to address both environmental and economic aspects to achieve a circular economy. LED lamps contain precious and critical metals, which can be found in electrical components and in the LED itself, making them a prospective waste for recycling initiatives. However, data about the concentration and distribution of these metals in the LED lamp’s components are still scarce and uncertain. This work aims to characterise the various components of different brands of LED lamps to provide novel data on the precious and critical metals’ amounts. Gold and silver were found in all brands of lamp, and we highlight the occurrence of gold in all analysed components, in concentrations between 0.01% and 0.07%, which is relevant to the economic viability of future recycling routes (gold and silver can contribute with USD 4340.00 per ton of LED lamps). The critical metals gallium, yttrium, and cerium were found in LEDs, while cobalt, barium, gallium, antimony, and manganese were found in printed circuit boards (PCBs). Additionally, the elements lead, cadmium, and arsenic were characterised due to their association with environmental and human toxicity.

description: Nanolayered post-transition metal monochalcogenides (PTMMCs) stand out as promising advanced two-dimensional (2D) materials. Beyond inheriting the general advantages associated with traditional 2D materials, they exhibit unique properties, including a wide bandgap range covering the ultraviolet to the mid-infrared spectral ranges, thickness-dependent bandgap behaviors, good nonlinear optical performance, high thermoelectric coefficients, and ferroelectricity. Consequently, these materials hold significant potential in diverse applications such as photodetectors, field effect transistors, thermoelectrics, ferroelectrics, photovoltaics, and electrochemical devices, especially in the manufacturing of nanoscale devices. However, there is still a lack of systematic understanding of the PTMMC family. This study provides a broad overview of the crystal structures, bandgap structures, synthesis methods, physical properties, and state-of-the-art applications of PTMMC materials with a motif of X-M-M-X (M=Ga, In, Ge, Sn; X=S, Se, Te). An outlook for the development trends is emphasized at the end, underscoring the critical importance of this work to the future exploration of nanolayered PTMMCs.

description: Farmers near towns and cities are using a wide range of highly polluted wastewaters for crop irrigation in Pakistan due to severe freshwater shortage. The present study aimed to promote indigenous bacterial strains isolated from domestic, hospital, textile, pharmaceutical and mixed wastewaters to remove contaminants and colour and render these wastewaters safer for irrigation. Thirty seven bacterial strains were isolated from five wastewater samples collected from different sites in Lahore, Pakistan. Under optimal growth conditions, three isolates (D6, D7 and P1) showed >93% decolourisation potential in the treatment of hospital wastewater. 16S rDNA sequencing identified two of these isolates (D6 and D7) as showing 100% and 99.86% homology to Bacillus paramycoides spp. – novel strains from B. cereus group. Isolate P1 showed 97.47% homology to Alcaligenes faecalis. GCMS analysis of the untreated hospital wastewater revealed the presence of pharmaceutic pollutants, i.e. Phenol (876 µg/L), Salicylic acid (48 µg/L), Caffeine (7 µg/L), Naproxen (23 µg/L), Octadecene (185 µg/L) and Diazepam (14 µg/L). The analysis of treated hospital wastewaters showed percentage degradation of pharmaceutic pollutants (100%–43%) and significant reduction in the BOD5 (91%–68%), COD (89%–52%) and heavy metals concentrations. These strains therefore can represent a low-cost and low-tech alternative to bioremediate complex matrices of hospital wastewater prior to crop irrigation to support the achievement of clean re-usable water in developing countries like Pakistan.

description: Copper(I) and palladium(II) complexes containing 5-acetyl-6-methyl-1,2,3,4-tetrahydropyrimidine-2-thione (L1), ethyl 4,6-dimethyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (L2), cis-5-acetyl-6-ethyl-5,6-dihydro-2-thiouracil (L3) and 5,6-dihydro-2-thiouracil (L4) have been synthesized. All complexes were characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy. To assign bands in the IR spectra of L1 and L2 and complexes with Cu(I) and Pd(II), deuterium substitution of movable protons at N-atoms was used. The crystal structures of two compounds, [Cu(L2)2Cl] and [Pd(L4)2Cl2], were determined by X-ray single-crystal and powder diffraction, respectively. In [Cu(L2)2Cl], copper has a rare coordination number of three and triangular surrounding of two neutral L2 molecules, coordinated through sulfurs, and chloride. In [Pd(L4)2Cl2], palladium has a standard square-planar geometry, formed by two uracil molecules and two chlorides. A new method for the synthesis of 5,6-dihydro-2-thiouracil, starting from β-aminopropionic acid, was suggested.

description: One way to make decisions under uncertainty is to select an optimal option from a possible range of options, by maximizing the expected utilities derived from a probability model. However, under severe uncertainty, identifying precise probabilities is hard. For this reason, imprecise probability models uncertainty through convex sets of probabilities, and considers decision rules that can return multiple options to reflect insufficient information. Many well-founded decision rules have been studied in the past, but none of those standard rules are able to control the number of returned alternatives. This can be a problem for large decision problems, due to the cognitive burden decision makers have to face when presented with a large number of alternatives. Our contribution proposes regret-based ideas to construct new decision rules which return a bounded number of options, where the limit on the number of options is set in advance by the decision maker as an expression of their cognitive limitation. We also study their consistency and numerical behaviour.

description: Hydrogen production through the processes of ethanol catalytic steam reforming (SR) is one of the promising routes due to its extensive yield that can be gained. However, catalyst deactivation (as a result of coke formation) is a major drawback in such a process. Therefore, this research work introduces efficient MgO supported Cubic cobalt oxide catalyst for the process of ethanol SR. This catalyst was successfully able to produce gases that have high contents of CO-free hydrogen was produced (above 78 %) at 500 oC and various flow rates of feed. This catalyst had also avoided coke formation at that temperature while attaining capture of the in-situ produced CO2 gas. The employment of an operating temperature beyond 500 oC, during the SR process, could reduce the percentages of hydrogen (in products) to less than 55 %. Such increases in the operational temperature could leave behind the detection of coke deposits onto the catalyst surface. The presence of these deposits was confirmed visually as well as via Raman spectroscopy.

description: Chromium and MnO2 free green synthesis of industrially important steroidal drug intermediate 16-dehydropregnenolone acetate (16-DPA) starting from diosgenin is reported. The reaction sequence involves three steps – acetolysis followed by acetylation, oxidation, and hydrolysis. In the first step, Ac2O was used both as reagent and solvent in combination with a Lewis acid (AlCl3), which led to considerable reduction of high temperature and pressure requirements of earlier processes. The oxidation step was made catalytic with the use of KMnO4(5 mol%) in presence of co-oxidant NaIO4 leading to lowering of the waste generation (Chromium, MnO2 etc.). Minimization of the temperature, pressure, time consumption, and use of nontoxic solvents makes the process very handy and simple.

description: Farmers near towns and cities are using a wide range of highly polluted wastewaters for crop irrigation in Pakistan due to severe freshwater shortage. The present study aimed to promote indigenous bacterial strains isolated from domestic, hospital, textile, pharmaceutical and mixed wastewaters to remove contaminants and colour and render these wastewaters safer for irrigation. Thirty seven bacterial strains were isolated from five wastewater samples collected from different sites in Lahore, Pakistan. Under optimal growth conditions, three isolates (D6, D7 and P1) showed >93% decolourisation potential in the treatment of hospital wastewater. 16S rDNA sequencing identified two of these isolates (D6 and D7) as showing 100% and 99.86% homology to Bacillus paramycoides spp. – novel strains from B. cereus group. Isolate P1 showed 97.47% homology to Alcaligenes faecalis. GCMS analysis of the untreated hospital wastewater revealed the presence of pharmaceutic pollutants, i.e. Phenol (876 µg/L), Salicylic acid (48 µg/L), Caffeine (7 µg/L), Naproxen (23 µg/L), Octadecene (185 µg/L) and Diazepam (14 µg/L). The analysis of treated hospital wastewaters showed percentage degradation of pharmaceutic pollutants (100%–43%) and significant reduction in the BOD5 (91%–68%), COD (89%–52%) and heavy metals concentrations. These strains therefore can represent a low-cost and low-tech alternative to bioremediate complex matrices of hospital wastewater prior to crop irrigation to support the achievement of clean re-usable water in developing countries like Pakistan.

description: Eight new C14-polyacetylenol glycosides, containing ene-diyne and ene-yn-ene chromophores named codonopilodiynosides H-M (1–6) and codonopiloenynenosides A and B (7 and 8), respectively, together with three known analogs lobetyolinin, pratialin B, and lobetyolin (9–11), were isolated from an aqueous extract of the roots of Codonopsis pilosula. Their structures were determined by spectroscopic and chemical methods including 2D NMR data analysis and enzymatic hydrolysis. The absolute configurations of aglycones in 1–10 were assigned by application of the methoxyphenylacetic acid (MPA) determination rule of ΔδRS values and/or the empirical rule of Mo2(OAc)4-induced circular dichroism for the vicinal diols, or by comparison of specific rotation values with those of reported compounds. Compounds 4–6 are the first polyacetylenol glycosides possessing a cis-ene-diyne chromophore from the genus Codonopsis, while 8 has a rear trans-ene-yn-cis-ene chromophore and a (6S,7S)-6,7-diol unit against a (6R,7R)-6,7-diol unit in the others. The absolute configurations of lobetyolinin (9) and pratialin B (10) were determined for the first time.

description: We consider a general statistical mechanics model on a product of local spaces and prove that, if the corresponding measure is reflection positive, then several site-monotonicity properties for the two-point function hold. As an application of such a general theorem, we derive site-monotonicity properties for the spin-spin correlation of the quantum Heisenberg antiferromagnet and XY model, we prove that such spin-spin correlations are point-wise uniformly positive on vertices with all odd coordinates -- improving previous positivity results which hold for the Cesàro sum -- and we derive site-monotonicity properties for the probability that a loop connects two vertices in various random loop models, including the loop representation of the spin O(N) model, the double-dimer model, the loop O(N) model, lattice permutations, thus extending the previous results of textitLees and Taggi (2019).

description: In this article, we study the generalized Duffin-Kemmer-Petiau (DKP) oscillator under the influence of quantum flux field in the topological defects produced by a cosmic string space-time and point-like global monopole. The generalized DKP oscillator will be investigated through a non-minimal substitution of the momentum operator $\vec{p} \to \left(\vec{p}+i\,M\,ω\,η^0\,f(r)\,\hat{r}\right)$ in the relativistic DKP equation. We solve this generalized DKP oscillator in a cosmic string space-time background and obtain the energy levels and wave function of the oscillator field using the parametric Nikiforov-Uvarov method. Afterwards, we solve the generalized DKP-oscillator in a point-like global monopole space-time and obtain the energy levels and wave functions following the same method. In fact, it is shown there that the energy eigenvalues are influenced by the topological defect of cosmic string and point-like global monopole and gets modified compared to flat space results, and breaks the degeneracy of the energy levels. Furthermore, we observe that the eigenvalue solutions depends on the quantum flux field that shows the gravitational analogue of the Aharonov-Bohm effect and also gives us a persistent currents

description: Phoenician archaeology has a long history of being defined and redefined. Up until today, academics and institutions often have variable approaches to and perceptions of Phoenician material culture. This history has impacted the treatment of this material culture in museums, resulting in very different approaches from one museum to the other. This paper presents a comparative approach to Phoenician collections on display in museums of different scales and in different countries, taking into considerations cues such as frequency and importance played by the Phoenicians within the larger context of the museum, the variable definitions of the word in each museum, and curatorial choices with the aim of understanding whether the scale of the museum is a key factor in its presentation of Phoenician collections.

description: Introduction La lombalgie est une problématique qui touche la majorité des gens au moins une fois dans leur vie. Son origine est multifactorielle et dans la majorité des cas, la cause n’est pas identifiable. Sa forte prévalence engendre des coûts considérables car elle est la cause numéro une de handicap fonctionnel. La diminution d’amplitude est un facteur contribuant de la lombalgie, cependant il n’est encore pas clair dans la littérature s’il est un facteur de handicap fonctionnel. Ce travail cherche donc à évaluer si l’amplitude du mouvement est liée au handicap fonctionnel et si lorsqu’un paramètre s’améliore l’autre s’améliore également. Méthodologie Ce travail s’inscrit dans le cadre d’une revue de la littérature et a été effectué en suivant un protocole inscrit sur PROSPERO. Des critères d’inclusion et d’exclusion ont défini cette sélection. Des équations ont été créé pour chaque base de données (PubMed, Embase, Cochrane, Pedro, CINAHL). La recherche à donner 6930 études sans les doublons. Un premier tri est effectué sur la base des titres et résumés et le second tri est effectué sur la base des textes intégraux. Une fois les études sélectionnées, un tableau d’extraction de donnée a été créé afin d’extraire les informations nécessaires pour ce travail. Résultats 32 études, avec un total de 3590 participants, sont inclues dans ce travail. Les corrélations qui concernent la relation en amplitude du mouvement et handicap fonctionnel sont pour la majorité (65%) faibles et positives. La presque totalité (85%) des corrélations qui portent sur l’amélioration de l’amplitude du mouvement et de la diminution du handicap fonctionnel sont faibles et positives. Discussion Ce travail montre que la relation entre amplitude de mouvement et handicap fonctionnel ainsi que la relation entre changement d’amplitude et changement de handicap fonctionnel n’est pas clairement établie et que, lorsque cette relation existe, elle est dans la majorité des cas avec des faibles valeurs. Conclusion L’absence de relation entre amplitude de mouvement et handicap fonctionnel et l’absence de relation entre amélioration de l’amplitude et l’amélioration du handicap fonctionnel chez la plupart des personnes lombalgiques sont supportées par les études disponibles. Cela démontre le peu d’influence que l’amplitude de mouvement a sur les limitations cela appuie l’importance des facteurs bio-psycho-sociaux.

description: This study aims to identify the plausible scenarios of tourism in Antalya, Turkey. For this purpose, the drivers and key factors of the research were first identified by reviewing the literature and interviewing Turkish tourism experts. Then these factors were screened using binomial nonparametric test and eight factors were eliminated from the 19 key factors. Two key factors of government policy in the tourism field and value of country currency were selected using cross impact analysis technique in order to write plausible scenarios. Based on these two uncertainties, four scenarios of luxury tourism, cheap tourism, tourism deterioration and unplanned tourism were identified.

description: Vision-Language Transformers (VLTs) have shown great success recently, but are meanwhile accompanied by heavy computation costs, where a major reason can be attributed to the large number of visual and language tokens. Existing token pruning research for compressing VLTs mainly follows a single-modality-based scheme yet ignores the critical role of aligning different modalities for guiding the token pruning process, causing the important tokens for one modality to be falsely pruned in another modality branch. Meanwhile, existing VLT pruning works also lack the flexibility to dynamically compress each layer based on different input samples. To this end, we propose a novel framework named Multimodal Alignment-Guided Dynamic Token Pruning (MADTP) for accelerating various VLTs. Specifically, we first introduce a well-designed Multi-modality Alignment Guidance (MAG) module that can align features of the same semantic concept from different modalities, to ensure the pruned tokens are less important for all modalities. We further design a novel Dynamic Token Pruning (DTP) module, which can adaptively adjust the token compression ratio in each layer based on different input instances. Extensive experiments on various benchmarks demonstrate that MADTP significantly reduces the computational complexity of kinds of multimodal models while preserving competitive performance. Notably, when applied to the BLIP model in the NLVR2 dataset, MADTP can reduce the GFLOPs by 80% with less than 4% performance degradation.
