description: Potential radioactive hazards in full-dose positron emission tomography (PET) imaging remain a concern, whereas the quality of low-dose images is never desirable for clinical use. So it is of great interest to translate low-dose PET images into full-dose. Previous studies based on deep learning methods usually directly extract hierarchical features for reconstruction. We notice that the importance of each feature is different and they should be weighted dissimilarly so that tiny information can be captured by the neural network. Furthermore, the synthesis on some regions of interest is important in some applications. Here we propose a novel segmentation guided style-based generative adversarial network (SGSGAN) for PET synthesis. (1) We put forward a style-based generator employing style modulation, which specifically controls the hierarchical features in the translation process, to generate images with more realistic textures. (2) We adopt a task-driven strategy that couples a segmentation task with a generative adversarial network (GAN) framework to improve the translation performance. Extensive experiments show the superiority of our overall framework in PET synthesis, especially on those regions of interest.

description: Observations of flare-heated electrons in the corona typically suggest confinement of electrons. The confinement mechanism, however, remains unclear. The transport of coronal hot electrons into ambient plasma was recently investigated by particle-in-cell (PIC) simulations. Electron transport was significantly suppressed by the formation of a highly localized, nonlinear electrostatic electric potential in the form of a double layer (DL). In this work large-scale PIC simulations are performed to explore the dynamics of DLs in larger systems where, instead of a single DL, multiple DLs are generated. The primary DL accelerates return current electrons, resulting in high velocity electron beams that interact with ambient ions. This forms a Buneman unstable system that spawns more DLs. Trapping of heated return current electrons between multiple DLs strongly suppresses electron transport. DLs also accelerate ambient ions and produce strong ion flows over an extended region. This clarifies the mechanism by which hot electrons in the corona couple to and accelerate ions to form the solar wind. These new dynamics in larger systems reveal a more likely picture of DL development and their impact on the ambient plasma in the solar corona. They are applicable to the preparation for in-situ coronal space missions like the Solar Probe Plus.

description: The Earth's ocean mass is only 2.3 x 10^{-4} of the whole planet mass. Even including water in the interior, it would be at most 10^{-3}-10^{-2}. Ancient Mars may have had a similar or slightly smaller water fraction. It is important to clarify the water delivery mechanism to rocky planets in habitable zones in exoplanetary systems, as well as that to the Earth and Mars. Here, we consider water delivery to planets by icy pebbles after the snowline inwardly passes the planetary orbits and derive the water mass fraction (f_{water}) of the final planet as a function of disk parameters and discuss the parameters that reproduce f_{water} comparable to that inferred for the Earth and ancient Mars. We calculate the growth of icy pebbles and their radial drift with a 1D model, and accretion of icy pebbles onto planets, by simultaneously solving the snowline migration and the disk dissipation, to evaluate f_{water} of the planets. We find that f_{water} is regulated by the total mass (M_{res}) of icy dust materials preserved in the outer disk regions at the timing (t = t_{snow}) of the snowline passage of the planetary orbit. Because M_{res} decays rapidly after the pebble formation front reaches the disk outer edge (at t = t_{pff}), f_{water} is sensitive to the ratio t_{snow}/t_{pff}, which is determined by the disk parameters. We find t_{snow}/t_{pff} < 10 or > 10 is important. Deriving an analytical formula for f_{water} that reproduces the numerical results, we find that f_{water} of a rocky planet near 1 au is ~ 10^{-4}-10^{-2}, in the disks with initial disk size ~ 30-50 au and the initial disk mass accretion rate ~ (10^{-8}-10^{-7}) M_sun/y. Because these disks may be median or slightly compact/massive disks, the water fraction of rocky planets in habitable zones may be often similar to that of the Earth, if the icy pebble accretion is responsible for the water delivery.

description: The adsorption of indole from carbon tetrachloride solution on mesoporous silica (MS) material was investigated by kinetic FTIR spectroscopic measurements. This result is correlated to the capability of indole N-H to participate in hydrogen bonding with the MS surface. Results of FTIR spectroscopy evidence the presence of indole adsorbed on the surface of MS while the analysis of hyperspectral images reveals the possibility of constructing effective qualitative hyperspectral sensors for indole based on MS as a sensing substrate.

description: Adaptation decision‐scientists increasingly use real‐option analysis to consider the value of learning about future climate variable development in adaptation decisions. Toward this end learning scenarios are needed, which are scenarios that provide information on future variable values seen not only from today (as static scenarios), but also seen from future moments in time. Decision‐scientists generally develop learning scenarios themselves, mostly through time‐independent (stationary) or highly simplified methods. The climate learning scenarios thus attained generally only poorly represent the uncertainties of state‐of‐the‐art climate science and thus may lead to biased decisions. This paper first motivates the need for learning scenarios by providing a simple example to illustrate characteristics and benefits of learning scenarios. Next, we analyze how well learning scenarios represent climate uncertainties in the context of sea level rise and present a novel method called direct fit to generate climate learning scenarios that outperforms existing methods. This is illustrated by quantifying the difference of the sea level rise learning scenarios created with both methods to the original underlying scenario. The direct fit method is based on pointwise probability distributions, for example, boxplots, and hence can be applied to static scenarios as well as ensemble trajectories. Furthermore, the direct fit method offers a much simpler process for generating learning scenarios from static or “ordinary” climate scenarios.

description: Cloudy conditions reduce the utility of optical imagery for crop monitoring. New constellations of satellites – including the RADARSAT Constellation Mission (RCM) and Sentinel-1A/B, both available under free and open data policies – can be used to create stacks of dense seasonal C-band Synthetic Aperture Radar (SAR) data. Yet to date, the contribution of SAR imagery to operational crop mapping is often limited to that of a gap-filler, compensating for optical data obscured by clouds. The Joint Experiment for Crop Assessment and Monitoring (JECAM) SAR Inter-Comparison Experiment is a multi-year, multi-partner project focused on evaluating methods for SAR-based crop classification. Stacks of dense time-series SAR imagery, from RADARSAT-2 and Sentinel-1 satellites, were acquired for 10 sites located in six countries. Decision Tree (DT) and Random Forest (RF) classification methodologies were applied to these SAR data-stacks, as well as to data-stacks of optical only, and optimized SAR/optical data combinations. For the dense time-series SAR stacks, overall classification accuracies above 85% and 80% were obtained for 6 of 10 and 8 of 10 sites, respectively. For maize, the SAR-only data delivered user’s and producer’s accuracies greater than 90% for half the sites. For soya bean, accuracies greater than 80% were reported for 5 of 9 sites and classification accuracies were greater than 80% for wheat on half the sites. Classification results were influenced by the mix and number of agriculture classes present at each site, the available SAR imagery, as well as the training and validation data sets for individual crop types. These results have important operational implications for regions of the world dominated by cloudy conditions and the lack of adequate amounts of optical imagery to support satellite-based crop monitoring.

description: We examine the mid-infrared fluxes and spectral energy distributions for metal-poor stars with iron abundances [Fe/H] $\lesssim-5$, as well as two CEMP-no stars, to eliminate the possibility that their low metallicities are related to the depletion of elements onto dust grains in the formation of a debris disk. Six out of seven stars examined here show no mid-IR excess. These non-detections rule out many types of circumstellar disks, e.g. a warm debris disk ($T\!\le\!290$ K), or debris disks with inner radii $\le1$ AU, such as those associated with the chemically peculiar post-AGB spectroscopic binaries and RV Tau variables. However, we cannot rule out cooler debris disks, nor those with lower flux ratios to their host stars due to, e.g. a smaller disk mass, a larger inner disk radius, an absence of small grains, or even a multicomponent structure, as often found with the chemically peculiar Lambda Bootis stars. The only exception is HE0107-5240, for which a small mid-IR excess near 10 microns is detected at the 2-$σ$ level; if the excess is real and associated with this star, it may indicate the presence of (recent) dust-gas winnowing or a binary system.

L’analisi globale (codicologica, paleografica, testuale e storico artistica), congiunta all’ analisi del materiale archivistico e delle testimonianze indirette, ha permesso di ricostruire un corpus dei codici decorati legati all’abbazia di Montevergine, giungendo a proporre anche nuove acquisizioni critiche. Indagare sulle immagini su pergamena ha portato in primis ad interrogarsi sulla presenza o meno dello scriptorium; una realtà complessa nel mondo verginiano e non perfettamente attestata in merito alla produzione libraria. Di grande interesse risulta l’analisi del documento illustrato noto come ‘lo Statuto dell’abate Donato’, di sicura produzione verginiana, del quale è scaturita una nuova lettura. [a cura dell'Autore]
description: The purpose of this study was the complete and detailed description of all the materials (parchments manuscripts, documents and fragments), dated between the 12th and the 13th centuries, through census and cataloging of the historical records preserved at the Biblioteca Nazionale at the Montevergine Abbey and at the Biblioteca Apostolica Vaticana. An important chapter in the history of the Abbey concerns the book decoration, a little studied subject, unlike the pictorial and sculptural productions. The global analysis (codicological, paleographical, textual and of the history of art), combined with the analysis of the archive materials and the indirect records, has allowed us to rebuild a corpus of the decorative codes linked to the Montevergine Abbey, as well as to propose new critical acquisitions. Searching for parchment images has led us to wonder about the presence of the scriptorium; a complex reality in the Virginian world that does not fully attest to the production of books. The analysis of illustrated documents known as ‘Statuto dell’abate Donato', a sure Virginian production, was of great interest and led to a new interpretation. [edited by Author]

description: A concise synthesis of the 1,4-diarylbutanoid–phenethylamine alkaloids, schwarzinicines A (1) and B (2), recently isolated from Ficus schwarzii, is reported. Key steps include a Claisen condensation to assemble the 1,4-diaryl-2-butanone intermediate, followed by a reductive amination to furnish the core skeleton of the target compounds. The overall synthetic yields of 1 and 2 were 9.1% and 3.5%, respectively. Synthetic (−)-1, (+)-1 and (±)-1 exhibited comparable vasorelaxation as natural schwarzinicine A on rat isolated aortic rings, suggesting that the observed vasorelaxant effects were not influenced by the chirality at C-2.

description: We study the behavior of the recently proposed "strange correlator" [Phys. Rev. Lett. {\bf 112}, 247202 (2014)] in spin-1 Heisenberg antiferromagnetic chains with uniaxial single-ion anisotropy. Using projective quantum Monte Carlo, we are able to directly access the strange correlator in a variety of phases, as well as to examine its critical behavior at the quantum phase transition between trivial and non-trivial symmetry protected topological phases. After finding the expected long-range behavior in these two symmetry conserving phases, we go on to verify the topological nature of two-leg and three-leg spin-1 Heisenberg antiferromagnetic ladders. This demonstrates the power of the strange correlator in distinguishing between trivial and non-trivial symmetry protected topological phases.

description: In the present study, the essential oil (EO) of Annona exsucca DC. or Rollinia exsucca was extracted by hydrodistillation, and the identification and quantification of volatile compounds were performed by GC-MS and GC-FID. A. exsucca leaves were collected from the Magalhães Barata, northeast of the State of Pará (Brazil) in March and September of 2019. Moreover, we used computational approaches to evaluate possible biological targets for the major compounds of the EO. In the sample obtained in March, 50 compounds were identified, with hydrocarbon sesquiterpenes being the predominant ones with the content of 80.52%. In the sample collected in September, 58 compounds were identified, and the chemical class of hydrocarbon monoterpenes and sesquiterpenes were the dominant ones with contents of 43.36 and 31.29%, respectively. Computational methods demonstrated that some major compounds have potential biological activity against some strains of pathogenic bacteria, as well as against molecular targets involved in cancer development.

description: Predicting both the time and the location of human movements is valuable but challenging for a variety of applications. To address this problem, we propose an approach considering both the periodicity and the sociality of human movements. We first define a new concept, Social Spatial-Temporal Event (SSTE), to represent social interactions among people. For the time prediction, we characterise the temporal dynamics of SSTEs with an ARMA (AutoRegressive Moving Average) model. To dynamically capture the SSTE kinetics, we propose a Kalman Filter based learning algorithm to learn and incrementally update the ARMA model as a new observation becomes available. For the location prediction, we propose a ranking model where the periodicity and the sociality of human movements are simultaneously taken into consideration for improving the prediction accuracy. Extensive experiments conducted on real data sets validate our proposed approach.

description: Speech technology is becoming ever more ubiquitous with the advance of speech enabled devices and services. The use of speech synthesis in Augmentative and Alternative Communication tools, has facilitated inclusion of individuals with speech impediments allowing them to communicate with their surroundings using speech. Although there are numerous speech synthesis systems for the most spoken world languages, there is still a limited offer for smaller languages. We propose and compare three models built using parametric and deep learning techniques for Macedonian trained on a newly recorded corpus. We target low-resource edge deployment for Augmentative and Alternative Communication and assistive technologies, such as communication boards and screen readers. The listening test results show that parametric speech synthesis is as performant compared to the more advanced deep learning models. Since it also requires less resources, and offers full speech rate and pitch control, it is the preferred choice for building a Macedonian TTS system for this application scenario.

description: We have obtained deep images of the highly isolated (d = 1 Mpc) Aquarius dwarf irregular galaxy (DDO 210) with the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). The resulting color-magnitude diagram (CMD) reaches more than a magnitude below the oldest main-sequence turnoff, allowing us to derive the star formation history (SFH) over the entire lifetime of the galaxy with a timing precision of ~10% of the lookback time. Using a maximum likelihood fit to the CMD we find that only ~10% of all star formation in Aquarius took place more than 10 Gyr ago (lookback time equivalent to redshift z ~2). The star formation rate increased dramatically ~6-8 Gyr ago (z ~ 0.7-1.1) and then declined until the present time. The only known galaxy with a more extreme confirmed delay in star formation is Leo A, a galaxy of similar M(HI)/M(stellar), dynamical mass, mean metallicity, and degree of isolation. The delayed stellar mass growth in these galaxies does not track the mean dark matter accretion rate from CDM simulations. The similarities between Leo A and Aquarius suggest that if gas is not removed from dwarf galaxies by interactions or feedback, it can linger for several gigayears without cooling in sufficient quantity to form stars efficiently. We discuss possible causes for the delay in star formation including suppression by reionization and late-time mergers. We find reasonable agreement between our measured SFHs and select cosmological simulations of isolated dwarfs. Because star formation and merger processes are both stochastic in nature, delayed star formation in various degees is predicted to be a characteristic (but not a universal) feature of isolated small galaxies.

description: The Catalogue of Heroines (Odyssey 11.225-330) presents a corpus of prominent mythological women as Odysseus recounts the stories of each woman he encounters in the Underworld. I undertook a TEI close reading of the Catalogue in order to center ancient women in a discussion of the Odyssey and determine how the relationships between the heroines contribute to the Catalogue’s overall purpose. In this short paper I demonstrate first my process: developing my own detailed feminist translation of the Catalogue, applying a TEI close reading to both my translation and the original ancient Greek, and creating a customized schema to best suit my purposes. Then, I detail my analysis of my close reading using cross-language encoding and a prosopography I developed through that reading, which reveals complex connections, both explicit and implied, among characters of the Catalogue. Third, I present the result of this analysis: that through this act of close reading I identified a heretofore unconsidered list of objects within the Catalogue and then demonstrated how these four objects of the Catalogue, ζώνη (girdle), βρόχοs (noose), ἕδνα (bride-price), and χρυσὸs (gold), reveal the ancient Greek stigma surrounding women, sexuality, and fidelity. These objects clearly allude to negative perceptions of women in ancient Greek society and through these objects the Catalogue of Heroines reminds its audience of Odysseus’ concerns regarding the faithfulness of his wife Penelope. Ultimately, by applying and adapting a TEI close reading, I identified patterns within the text that spoke to a greater purpose for the Catalogue and the Odyssey overall, that was able to export for further analysis of this prosopographical data. I also present data visualizations that provide pathways that can assist other classicists to center women in ancient texts.

description: Ultra-fast outflows (UFOs) are seen in many AGN, giving a possible mode for AGN feedback onto the host galaxy. However, the mechanism(s) for the launch and acceleration of these outflows are currently unknown, with UV line driving apparently strongly disfavoured as the material along the line of sight is so highly ionised that it has no UV transitions. We revisit this issue using the Suzaku X-ray data from PDS 456, an AGN with the most powerful UFO seen in the local Universe. We explore conditions in the wind by developing a new 3-D Monte-Carlo code for radiation transport. The code only handles highly ionised ions, but the data show the ionisation state of the wind is high enough that this is appropriate, and this restriction makes it fast enough to explore parameter space. We reproduce the results of earlier work, confirming that the mass loss rate in the wind is around 30% of the inferred inflow rate through the outer disc. We show for the first time that UV line driving is likely to be a major contribution to the wind acceleration. The mass loss rate in the wind matches that predicted from a purely line driven system, and this UV absorption can take place out of the line of sight. Continuum driving should also play a role as the source is close to Eddington. This predicts that the most extreme outflows will be produced from the highest mass accretion rate flows onto high mass black holes, as observed.

Critical behavior and universality properties of uniaxial ferromagnetic thin films in the presence of random magnetic fields

description: Critical phenomena in uniaxial ferromagnetic thin films in the presence of random magnetic fields have been studied within the framework of effective field theory. When the type of the random field distribution is bimodal, the system exhibits tricritical behavior. Furthermore, the critical value of surface to bulk ratio of exchange interactions at which the transition temperature becomes independent of film thickness is insensitive to the presence of disorder whether the distribution is bimodal or trimodal. Regarding the universality properties, neither $p$, nor $h$ variations in the system can affect the value of the shift exponent $λ$. In this regard, it can be concluded that pure ferromagnetic thin films are in the same universality class with those under the influence of random discrete magnetic fields.

description: Die vorliegende Bachelor-Arbeit Einleben und dazugehören widmet sich der Fragestellung «Wie erleben Mineur*es Non Accompagné*es den Zugehörigkeitsprozess in der Schweiz und welche Chancen und Herausforderungen ergeben sich dabei?». Für die Bearbeitung der Fragestellung und den daraus ableitenden Handlungsempfehlungen für die Soziale Arbeit haben sich die Autorinnen Elena Argenti und Sabrina Fernández für eine qualitative Forschungsarbeit entschieden. Die dargestellten theoretischen Ansätze dienen der Erläuterung der Komplexität der Zugehörigkeit sowie der damit einhergehenden Zusammenhänge. Anhand von acht leitfadengestützten Interviews mit unbegleiteten, geflüchteten Minderjährigen konnte deren Sichtweise in Bezug auf ihren Zugehörigkeitsprozess in der Schweiz beleuchtet werden. Die Verknüpfung der Aussagen aus den geführten Interviews mit den theoretischen Grundlagen erfolgte mittels der Methode der Inhaltsanalyse. Aus den daraus gewonnenen Erkenntnissen resultiert, dass sich der Zugehörigkeitsprozess nicht nur sehr individuell gestaltet, sondern auch von vorherrschenden Strukturen bedingt wird. Die Handlungsempfehlungen leiten sich aus den erzielten Ergebnissen ab und bieten eine Aussicht auf künftige Entwicklungen.

description: The $Λ$ separation energy for $Λ$-hypernuclei, denoted $B_Λ$, measured in 1967, 1968, and 1973 are recalibrated using the current best mass estimates for particles and nuclei. The recalibrated $B_Λ$ are systematically larger (except in the case of $^6_Λ$He) than the original published values by about 100 keV. The effect of this level of recalibration is very important for light hypernuclei, especially for the hypertriton. The early $B_Λ$ values measured in 1967, 1968, and 1973 are widely used in theoretical research, and the new results provide better constraints on the conclusions from such studies.
