description: This work was performed to dig into the phytochemical composition and bioactivities of Nocardiopsis sp. UR67 associated with the marine sponge Callyspongia sp. It was fermented in suspension and immobilised in calcium alginate bead cultures. The ethyl acetate extracts, afforded from the broth in each case named EG-49 and J-48g, respectively, revealed 16 chemical principles mostly belonging to polyketides, macrolides, and peptides. EG-49 and J-48g displayed anti-Candida albicans activity with IC50 values of 8.1 and 8.3 µg/mL, and a substantial cytotoxic effect against lung adenocarcinoma H1650 at IC50 12.6 and 13.7 µg/mL, respectively. However, only EG-49 exhibited a noteworthy anti-trypanosomal activity at 7.5 µg/mL. Molecular docking of the characterised compounds against Trypanosoma brucei trypanothione reductase demonstrated the highest binding models of griseochelin-methyl ester (9) and filipin-II (11), which drew considerable significance of the metabolites derived from Nocardiopsis sp. UR67 developing potential T. brucei trypanothione reductase inhibitors.

description: Boerhavia erecta is a tropical plant that is widely used in Asian folk medicine. Little is known about the alpha-glucosidase inhibition and antimicrobial properties of compounds from this plant. In the present study, the phytochemical study of the aerial parts of B. erecta collected in Vietnam was conducted using multiple chromatographic methods. The chemical structures of isolated compounds were identified by comprehensive spectroscopic methods. Two new compounds, berectone C (1) and (E)-tetracosyl 3-(3-hydroxy-4-methoxyphenyl)acrylate (4), together with the known compounds boeravinone C (2), liquiritigenin (3), bis(1H-indol-3-yl)methanone (5), and indole-3-carboxylic acid (6) were isolated and structural elucidated. Compounds 1 and 4 were evaluated for alpha-glucosidase inhibition and antimicrobial activity against antibiotic-resistant, pathogenic bacteria Enterococcus faecium, Staphylococcus aureus, and Acinetobacter baumannii. Compound 1 showed strong inhibition of the alpha-glucosidase enzyme (IC50 43 µg/mL). Only compound 1 exhibited antimicrobial property against A. baumannii, forming an inhibition zone of 11 mm.

description: Eruptive phenomena such as plasmoid ejections or jets are an important feature of solar activity with the potential for improving our understanding of the dynamics of the solar atmosphere. Such ejections are often thought to be signatures of the outflows expected in regions of fast magnetic reconnection. The 304 A EUV line of Helium, formed at around 10^5 K, is found to be a reliable tracer of such phenomena, but the determination of physical parameters from such observations is not straightforward. We have observed a plasmoid ejection from an X-ray bright point simultaneously at millimeter wavelengths with ALMA, at EUV wavelengths with AIA, in soft X-rays with Hinode/XRT. This paper reports the physical parameters of the plasmoid obtained by combining the radio, EUV and X-ray data. As a result, we conclude that the plasmoid can consist either of (approximately) isothermal 10^5 K plasma that is optically thin at 100 GHz, or else a 10^4 K core with a hot envelope. The analysis demonstrates the value of the additional temperature and density constraints that ALMA provides, and future science observations with ALMA will be able to match the spatial resolution of space-borne and other high-resolution telescopes.

description: Σκοπός: Ο σκοπός της έρευνας είναι να μελετήσει το βαθμό στον οποίο το management μπορεί να επηρεαστεί από τη συναισθηματική νοημοσύνη. Δείγμα: 100 διευθυντές της πρωτοβάθμιας εκπαίδευσης που εργάζονται στο νομό Αττικής. Το δείγμα ήταν τυχαίο και κάθε εκπαιδευτικός είχε ακριβώς τις ίδιες πιθανότητες να συμπεριληφθεί στο δείγμα. Με το τυχαίο δείγμα επιτυγχάνεται η αντιπροσωπευτικότητα του δείγματος κι έτσι τα δεδομένα μπορούν να γενικευθούν στον πληθυσμό. Ερευνητικό εργαλείο: Το ερευνητικό εργαλείο ήταν το ερωτηματολόγιο. Αρχικά υπήρχαν πέντε ερωτήσεις για τα δημογραφικά χαρακτηριστικά του δείγματος δηλαδή το φύλο, την ηλικία, την οικογενειακή κατάσταση, το μορφωτικό επίπεδο και τα χρόνια προϋπηρεσίας. Έπειτα υπήρχε το ερωτηματολόγιο της συναισθηματικής νοημοσύνης των Salovey & Mayer (1990) και αποτελείται από 17 ερωτήσεις. Στη συνέχεια υπήρχαν οι 21 ερωτήσεις του ερωτηματολογίου της πολλαπλής ηγεσίας των Bass & Avolio (2004). Αποτελέσματα: Τα αποτελέσματα της έρευνας έδειξαν ότι οι εκπαιδευτικοί είχαν μέτριο επίπεδο συναισθηματικής νοημοσύνης. Το στυλ που εφάρμοζαν οι διευθυντές τους ήταν κυρίως το μετασχηματιστικό, καθώς οι τρεις διαστάσεις του συγκέντρωσαν την υψηλότερη βαθμολογία. Υπάρχει σύνδεση ανάμεσα στα χαρακτηριστικά της μετασχηματιστικής ηγεσίας και στην έκβαση της. Η σύνδεση αυτή είναι στατιστικά σημαντική. Η έκβαση της εργασίας αναφέρεται στην εργασιακή ικανοποίηση των εκπαιδευτικών, στην αποτελεσματικότητα του έργου τους και στην προσπάθεια που κάνουν καθημερινά. Συμπεράσματα: Ο βαθμός της συναισθηματικής νοημοσύνης των εκπαιδευτικών της πρωτοβάθμιας εκπαίδευσης είναι πολύ σημαντικός ώστε εκείνοι να παράγουν ένα πιο ποιοτικό έργο αλλά και ταυτόχρονα να μπορούν να επιλύουν όποια προβλήματα δημιουργούνται. Η μετασχηματιστική ηγεσία που εφάρμοζαν οι διευθυντές των σχολείων τους ήταν καθοριστικής σημασίας για την ανάπτυξη ή μη της συναισθηματικής νοημοσύνης.

Στον τομέα της εκπαίδευσης επέφερε πρωτοφανείς αλλαγές, καθώς έπρεπε να αντιμετωπιστούν μια σειρά προκλήσεων που αφορούσαν δυο βασικούς πυλώνες αυτού: τη διαφύλαξη της υγείας μαθητών-εκπαιδευτικών και την απρόσκοπτη διεξαγωγή της εκπαιδευτικής διαδικασίας.

We show that the [3.4]-[12] versus [4.6]-[22] colour-colour diagram is most suitable for separating C-rich/O-rich AGB and post- AGB star candidates. We are able to select 2,510 AGB and 24,821 post-AGB star candidates. However, the latter are severely mixed with the known young stellar objects in this diagram.

Videoconferencing-as-a-Service for African NRENs
Creators: name: Bristow, Rob
Publisher: name: UbuntuNet Alliance
Year: 2016
Subjects: NREN

description: The suggestion has been made (Bristow et al. 2015) (Isaac 2015) that there is an opportunity to leverage the installed infrastructure for both Video and Web conferencing in South Africa to extend the services to the NRENs that make up the UbuntuNet Alliance. Videoconferencing is one of the common services offered by many NRENs worldwide, and there are indications that this kind of service may be offered at a meta-NREN level (Géant). Experience over the past year has shown that, with respect to videoconferencing using Vidyo, there are no insurmountable technological or licencing barriers to rolling out such a service and there are indications that there would be few if any barriers to extending the paradigm to encompass web-conferencing using MConf. This paper will present a costed rollout plan for videoconferencing and web-conferencing for the UbuntuNet Alliance community. It will demonstrate the way that both platforms can share infrastructure across borders where appropriate (to share licensing and user account management) while deploying other infrastructure (to handle media traffic associated with calls and meetings) locally as required. The architectural aim is to minimise out of country traffic, while enabling optimal network conditions for inter-country calls and meetings, and allowing best quality international connectivity. Likely deployments for videoconferencing would be along the lines of VidyoRouters and VidyoGateways and MConf servers at appropriate places (in time at core points on each NREN’s network) connecting back to the core infrastructure in Cape Town, Johannesburg and Durban in South Africa. There would be an additional package of training for admins and operators and depending on budgetary availability, the opportunity to set up some suitably equipped meeting rooms and facilities in each NRENs territory. The advantages of this approach was developed at some length in the paper cited above, but to summarise: they are to be found in cost savings from a shared hybrid cloud type of deployment, the easing of collaboration by the adoption of a common platform, and in the opportunities for mutual support and community building.

description: This work explores the Zn vacancy in ZnO using hybrid density functional theory calculations. The Zn vacancy is predicted to be an exceedingly deep polaronic acceptor that can bind a localized hole on each of the four nearest-neighbor O ions. The hole localization is accompanied by a distinct outward relaxation of the O ions, which leads to lower symmetry and reduced formation energy. Notably, we find that initial symmetry-breaking is required to capture this effect, which might explain the absence of polaronic hole localization in some previous hybrid density functional studies. We present a simple model to rationalize our findings with regard to the approximately equidistant thermodynamic charge-state transition levels. Furthermore, by employing a one-dimensional configuration coordinate model with parameters obtained from the hybrid density functional theory calculations, luminescence lineshapes were calculated. The results show that the isolated Zn vacancy is unlikely to be the origin of the commonly observed luminescence in the visible part of the emission spectrum from \textit{n}-type material, but rather the luminescence in the infrared region.

Pulsating low-mass white dwarfs in the frame of new evolutionary sequences: IV. The secular rate of period change

description: We present a theoretical assessment of the expected temporal rates of change of periods ($\dotΠ$) for low-mass ($M_{\star}/M_{\sun} \lesssim 0.45$) and extremely low-mass (ELM, $M_{\star}/M_{\sun} \lesssim 0.18-0.20$) white-dwarf stars, based on fully evolutionary low-mass He-core white dwarf and pre-white dwarf models. Our analysis is based on a large set of adiabatic periods of radial and nonradial pulsation modes computed on a suite of low-mass He-core white dwarf and pre-white dwarf models with masses ranging from $0.1554$ to $0.4352 M_{\sun}$. We compute the secular rates of period change of radial ($\ell= 0$) and nonradial ($\ell= 1, 2$) $g$ and $p$ modes for stellar models representative of ELMV and pre-ELMV stars, as well as for stellar objects that are evolving just before the occurrence of CNO flashes at the early cooling branches. We found that the theoretically expected magnitude of $\dotΠ$ of $g$ modes for pre-ELMVs are by far larger than for ELMVs. In turn, $\dotΠ$ of $g$ modes for models evolving before the occurrence of CNO flashes are larger than the maximum values of the rates of period change predicted for pre-ELMV stars. Regarding $p$ and radial modes, we found that the larger absolute values of $\dotΠ$ correspond to pre-ELMV models. We conclude that any eventual measurement of a rate of period change for a given pulsating low-mass pre-white dwarf or white dwarf star could shed light about its evolutionary status. Also, in view of the systematic difficulties in the spectroscopic classification of stars of the ELM Survey, an eventual measurement of $\dotΠ$ could help to confirm that a given pulsating star is an authentic low-mass white dwarf and not a star from another stellar population.

Mass-Observation, surrealist sociology, and the bathos of paperwork
Creators: name: Jardine, Boris Samuel
Publisher: name: Apollo - University of Cambridge Repository
Year: 0

description: British social survey movement 'Mass-Observation' (M-O) was founded in 1937 by a poet, a film-maker and an anthropologist. It purported to offer a new kind of sociology – one inflected by surrealism and working with a 'mass' of observers, all recording day-to-day interactions. Various commentators of have debated the importance and precise identity of M-O in its first phase, especially in light of its combination of social science and surrealism. In this paper I argue that M-O is best characterised as a distinctive moment in which heterodox sociology and late surrealism came together in a visionary archival project. I draw on new archival research, in particular into the 'paperwork' practices of Charles Madge, and on recent synthetic accounts of M-O that have emerged in literary studies. In combining this with an account of M-O in relation to contemporary 'scientific humanism' I aim to resolve some of the apparent paradoxes that have been prominent in studies of M-O, and to describe the unfulfilled promise of a vast archive of social data.

description: How the time evolution which is typical for classical cosmology emerges from quantum cosmology? The answer is not trivial because the Wheeler-DeWitt equation is time independent. A framework associating the quantum Hamilton-Jacobi to the minisuperspace cosmological models has been introduced in [1]. In this paper, we show that time dependence and quantum-classical correspondence both arise naturally in the quantum Hamilton-Jacobi formalism of quantum mechanics applied to quantum cosmology. We study the quantum Hamilton-Jacobi cosmology of spatially flat homogeneous and isotropic early universe whose matter content is a perfect fluid. The classical cosmology emerge around one Planck time where its linear size is around a few millimeter, without needing any classical inflationary phase afterwards to make it grow to its present size.

title: Global Value Chains in the European Union: an input-output approach
Creators: name: de los Ángeles Gómez Benítez, María
Publisher: name: The Open University
Year: 2022

description: This thesis explores the role of Global Value Chains (GVCs) in the structure of production and final export dynamics in the EU for the period 2000-2014. It also distinguishes between the EU core and periphery regions according to the domestic wage level and subsystem groups. Drawing on classical economics and input-output techniques, this thesis develops an original accounting framework that provides three new measures that deepen our understanding of the impact of GVCs on EU export performance and cost structures. First, it offers a new decomposition of final exports into two nominal variables (exchange rates and price indices) and two real variables (physical labour productivity and quantity of labour induced foreign demand). Second, inspired by Braun’s unequal exchange model, it proposes a (previously unexplored) contrafactual exercise to estimate the labour cost-saving in GVCs through the vertically integrated distribution of labour and vertically integrated nominal wages, disaggregated by geographic origin. Finally, it suggests an original measure of unit labour costs based on the vertical integration approach, which is based on physical units of production instead of income distribution variables based on value added. Empirically, the thesis fills the existing literature gaps by addressing three objectives. First, it identifies monetary factors (the exchange rate and price index) as the main drivers of economic activity in the EU region, while real variables (productivity and required labour) lead the growth of final exports in the EU periphery. Second, this work finds that the international wage cutting strategy positively affects the EU core GVCs, but not the EU periphery. Nevertheless, in both cases, this wage cutting strategy slows down improvements in labour productivity, particularly in the core region. Finally, in the short run, the wage cutting strategy can help to sustain final export competitiveness, but in the long run this requires an improvement in technical conditions.

description: In various situations where wave transport is preeminent, like in wireless communication, a strong established transmission is present in a complex scattering environment. We develop a novel approach to describe emerging fluctuations, which combines a transmitting channel and a chaotic background in a unified effective Hamiltonian. Modeling such a background by random matrix theory, we derive exact non-perturbative results for both transmission and reflection distributions at arbitrary absorption that is typically present in real systems. Remarkably, in such a complex scattering situation, the transport is governed by only two parameters: an absorption rate and the ratio of the so-called spreading width to the natural width of the transmission line. In particular, we find that the established transmission disappears sharply when this ratio exceeds unity. The approach exemplifies the role of the chaotic background in dephasing the deterministic scattering.

description: DDO68 (UGC5340) is an unusual dwarf galaxy with extremely low gas metallicity (12+log(O/H) = 7.14) residing in the nearby Lynx-Cancer void. Despite its apparent isolation, it shows both optical and HI morphological evidence for strong tidal disturbance. Here, we study the resolved stellar populations of DDO68 using deep images from the HST archive. We determined a distance of 12.75+-0.41 Mpc using the tip of the red giant branch (TRGB). The star formation history reconstruction reveals that about 60 per cent of stars formed during the initial period of star formation, about 12-14 Gyr ago. During the next 10 Gyr DDO68 was in the quenched state, with only slight traces of star formation. The onset of the most recent burst of star formation occurred about 300 Myr ago. We find that young populations with ages of several million to a few hundred million years are widely spread across various parts of DDO68, indicating an intense star formation episode with a high mean rate of 0.15 Msun/yr. A major fraction of the visible stars in the whole system (~80 per cent) have low metallicities: Z = Zsun/50 - Zsun/20. The properties of the northern periphery of DDO68 can be explained by an ongoing burst of star formation induced by the minor merger of a small, gas-rich, extremely metal-poor galaxy with a more typical dwarf galaxy. The current TRGB-based distance of DDO68 implies a total negative peculiar velocity of ~500 km/s.

description: We present the first X-ray study of Collinder 261 (Cr261), which at an age of 7 Gyr is one of the oldest open clusters known in the Galaxy. Our observation with the Chandra X-ray Observatory is aimed at uncovering the close interacting binaries in Cr261, and reaches a limiting X-ray luminosity of Lx ~ 4e29 erg/s (0.3-7 keV) for stars in the cluster. We detect 107 sources within the cluster half-mass radius r_h, and we estimate that among the sources with Lx >~ 1e30 erg/s, ~26 are associated with the cluster. We identify a mix of active binaries and candidate active binaries, candidate cataclysmic variables, and stars that have "straggled" from the main locus of Cr261 in the colour-magnitude diagram. Based on a deep optical source catalogue of the field, we estimate that Cr261 has an approximate mass of 6500 M_sun, roughly the same as the old open cluster NGC6791. The X-ray emissivity of Cr261 is similar to that of other old open clusters, supporting the trend that they are more luminous in X-rays per unit mass than old populations of higher (globular clusters) and lower (the local neighbourhood) stellar density. This implies that the dynamical destruction of binaries in the densest environments is not solely responsible for the observed differences in X-ray emissivity.

Solitary waves for nonlinear Schrödinger equation with derivative

description: In this paper, we characterize a family of solitary waves for NLS with derivative (DNLS) by the structue analysis and the variational argument. Since (DNLS) doesn't enjoy the Galilean invariance any more, the structure analysis here is closely related with the nontrivial momentum and shows the equivalence of nontrivial solutions between the quasilinear and the semilinear equations. Firstly, for the subcritical parameters $4ω>c^2$ and the critical parameters $4ω=c^2, c>0$, we show the existence and uniqueness of the solitary waves for (DNLS), up to the phase rotation and spatial translation symmetries. Secondly, for the critical parameters $4ω=c^2, c\leq 0$ and the supercritical parameters $4ω0$ or $4ω>c^2$. On one hand, different with the scattering result for the $L^2$-critical NLS in \cite{Dod:NLS_sct}, the scattering result of (DNLS) doesn't hold for initial data in $\mathcal{K}^+_{ω,c}$ because of the existence of infinity many small solitary/traveling waves in $\mathcal{K}^+_{ω,c},$ with $4ω=c^2, c>0$ or $4ω>c^2$. On the other hand, our global result improves the global result in \cite{Wu-DNLS, Wu-DNLS2} (see Corollary \ref{cor:gwp}).

description: In the extragalactic sky, microquasars and ultra-luminous X-ray sources (ULXs) are known as energetic compact objects locating at off-nucleus positions in galaxies. Some of these objects are associated with expanding bubbles with a velocity of 80-250 ${\rm km~s^{-1}}$. We investigate the shock acceleration of particles in those expanding nebulae. The nebulae having fast expansion velocity $\gtrsim120~{\rm km~s^{-1}}$ are able to accelerate cosmic rays up to $\sim100$ TeV. If 10% of the shock kinetic energy goes into particle acceleration, powerful nebulae such as the microquasar S26 in NGC 7793 would emit gamma rays up to several tens TeV with a photon index of $\sim2$. These nebulae will be good targets for future Cherenkov Telescope Array observations given its sensitivity and angular resolution. They would also contribute to $\sim7$% of the unresolved cosmic gamma-ray background radiation at $\ge0.1~{\rm GeV}$. In contrast, particle acceleration in slowly expanding nebulae $\lesssim120~{\rm km~s^{-1}}$ would be less efficient due to ion-neutral collisions and result in softer spectra at $\gtrsim10$ GeV.

description: Phytochemical investigation of the methanol extracts from the leaves and bark of Senna siamea resulted in the isolation of one new flavone C-glycoside: apigenin-8-C-[6''-(E)-feruloyl]-β-D-glucopyranoside] (1), together with sixteen known compounds including quercetin-3-O-α-L-rhamnoside (2), vitexin (3), isovitexin (4), quercetin-3-O-β-D-glucopyranoside (5), quercetin-3-O-β-D-arabinopyranoside (6), quercetin (7), kaempferol (8), methyl inositol (9), sucrose (10), betulinic acid (11), vanillic acid (12), stigmastane-3β,6α-diol (13), aurantiamide acetate (14), robinetinidol (15), catechin (16) and epicatechin (17). The structures of these compounds were established on the basis of their spectroscopic (1 D and 2 D NMR) and mass spectrometric (ESI-TOF-MS) data. The methanol extracts, fractions and some of the isolated compounds were screened for their antimicrobial properties against five microbial strains. The methanol extract and the ethyl acetate fraction from the bark showed very weak antifungal activity against C. glabrata with the same MIC value of 128 μg/mL. Compound 7 was weakly active against C. albicans with MIC of 32 μg/mL.

description: The exciting discovery of topological condensed matter systems has lately triggered a search for their photonic analogs, motivated by the possibility of robust backscattering-immune light transport. However, topological photonic phases have so far only been observed in photonic crystals and waveguide arrays, which are inherently physically wavelength scaled, hindering their application in compact subwavelength systems. In this letter, we tackle this problem by patterning the deep subwavelength resonant elements of metamaterials onto specific lattices, and create crystalline metamaterials that can develop complex nonlocal properties due to multiple scattering, despite their very subwavelength spatial scale that usually implies to disregard their structure. These spatially dispersive systems can support subwavelength topological phases, as we demonstrate at microwaves by direct field mapping. Our approach gives a straightforward tabletop platform for the study of photonic topological phases, and allows to envision applications benefiting the compactness of metamaterials and the amazing potential of topological insulators.
