description: This study aims to provide information about the chemical profile of the essential oil from C. langsdorffii resin in areas of Cerradão, Carrasco, and Humid Forest. In order to obtain the essential oils, oil-resin was submitted to hydrodistillation process, and the chemical components were analyzed by gas chromatography coupled to mass spectrometry (GC/MS). Twenty-six constituents were identified in the essential oil of C. langsdorffii resin, of which 12 were present in Cerradão, 15 in Carrasco and 18 in Humid Forest, with β-bisabolene, caryophyllene oxide, γ-muurolene, α-caryophyllene and β-caryophyllene common to the three phytophysiognomies. Among the studied areas, the resin collection varied from 2.652 g to 20.263 g, while the essential oil yield varied from 2.216 % to 11.764 %. A concentration range of 0.60 % to 84.57 % was recorded among the compounds in the three study areas. There was variation in chemical composition both among phytophysiognomies and among individuals from the same location, where β-caryophyllene showed to be the majority for all areas studied, being present in all individuals from Cerradão, Carrasco and Humid Forest.

description: Electronic, lattice, and spin interactions at the interfaces between crystalline complex transition metal oxides can give rise to a wide range of functional electronic and magnetic phenomena not found in bulk. At hetero-interfaces, these interactions may be enhanced by combining oxides where the polarity changes at the interface. The physical structure between non-polar SrTiO$_3$ and polar La$_{1-x}$Sr$_x$MnO$_3$(x=0.2) is investigated using high resolution synchrotron x-ray diffraction to directly determine the role of structure in compensating the polar discontinuity. At both the oxide-oxide interface and vacuum-oxide interfaces, the lattice is found to expand and rumple along the growth direction. The SrTiO$_3$/La$_{1-x}$Sr$_x$MnO$_3$ interface also exhibits intermixing of La and Sr over a few unit cells. The results, hence, demonstrate that polar distortions and ionic intermixing coexist and both pathways play a significant role at interfaces with polar discontinuities.

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: This deliverable reports on four main activities of Work Package 2 (WP2) during the first reporting period of the PRACE-6IP project: Status of PRACE 2; Support in defining PRACE role in the European HPC ecosystem in the EuroHPC era; PRACE services for EuroHPC; Legal support to PRACE Infrastructure and other work packages of the project. The reporting on the PRACE 2 status within the PRACE Implementation Phase projects was initiated during PRACE-4IP (D2.2 “Second Report on PRACE 2.0 Development”) and continued during PRACE-5IP (D2.1 “Report on PRACE 2, TNA, DECI and KPIs Year 1”1 and D2.3 “Report on PRACE 2, TNA and DECI Year 2”). This deliverable provides an update on this activity undertaken within the first year of the PRACE-6IP project. It reports on the status of the implementation and developments in the Second Period of operations of the PRACE pan-European Research Infrastructure, called PRACE 2, which began in 2017 and succeeded the PRACE agreement for the Initial Period (referred to as PRACE 1).
 The main focus of this deliverable represents the European HPC ecosystem in the EuroHPC era and PRACE’s role in relation to other HPC stakeholders and EuroHPC. After the organisation of several meetings with the European HPC stakeholders, PRACE defines its position towards EuroHPC and services it could offer, as well as the relations and overlaps of all main actors in the ecosystem. The new “HPC in Europe” portal (under development) established by PRACE is meant to reflect the well-established roles and provide the users a good overview of the current HPC services at a European level.
 The COVID-19 pandemic caused new and exceptional circumstances all over the world. A dedicated section reports on the legal and financial implications of the COVID-19 pandemic on the project. We also report on the practices of different project partners related to COVID-19 and on several initiatives that PRACE or PRACE partners started or joined in order to support the fight against the COVID-19.

description: Seseli L. genus, belonging to the Apiaceae family, includes more than eighty taxa, mainly growing in Europe and Asia. Due to the several biological properties, species of this genus have been largely investigated, showing to be a rich source of coumarins, as well as, of essential oils with anti-inflammatory, antiviral, antifungal, cytotoxic, etc. properties. In the present study, the chemical composition of the essential oils from aerial parts of Sicilian accessions of Seseli tortuosum subsp. tortuosum and S. tortuosum subsp. maritimum were analysed by GC-MS. No one report has been previously published on the subsp. maritimum. The results showed the presence, in both oils, of large quantity of monoterpene hydrocarbons. Main metabolites were β-pinene (15.81-19.84%), α-pinene (14.63–18.52%), sylvestrene (11.18–17.45%) and 3-carene (14.58%), the last one being absent in the oil of subsp. maritimum. Chemotaxonomic considerations with respect to other oils of Seseli taxa were carried out.

description: Asteroid families are valuable source of information to many asteroid-related re- searches, assuming a reliable list of their members could be obtained. However, as the number of known asteroids increases fast it becomes more and more difficult to obtain robust list of members of an asteroid family. Here we are proposing a new approach to deal with the problem, based on the well known Hierarchical Clustering Method (HCM). An additional step in the whole procedure is introduced in order to reduce a so-called chaining effect. The main idea is to prevent chaining through an al- ready identified interloper. We show that in this way a number of potential interlopers among family members is significantly reduced. Moreover, we developed an automatic on-line based portal to apply this procedure, i.e to generate a list of family members as well as a list of potential interlopers. The Asteroid Families Portal (AFP) is freely available to all interested researchers.

description: Bene gum was investigated for its physicochemical and structural properties in comparison to gum arabic and gum tragacanth. Elemental analysis of the Bene gum sample revealed sodium and potassium content to be 57.21 and 0.95 ppm, respectively. According to the rheological properties, all gum solutions exhibited non-Newtonian, shear-thinning in the concentration of 1% (w/w). Both storage modulus G′ and loss modulus G″ of all gums demonstrated elastic properties. The GC–MS analysis of dichloromethane extract confirmed the presence of eight constituents and α-pinene is the predominant constituent. The NMR spectra of the gum sample showed resemblance in individual sugar ingredients and the specific patterns of gum were observed. FTIR spectra of the studied gums displayed the presence of the same functional groups in the three gums. XRD studies revealed the amorphous nature of Bene gum. DSC and TGA thermograms were characteristic for each gum. Major thermal transitions were determined.

description: We give a systematic procedure to evaluate conformal partial waves involving symmetric tensors for an arbitrary CFT$_d$ using geodesic Witten diagrams in AdS$_{d+1}$. Using this procedure we discuss how to draw a line between the tensor structures in the CFT and cubic interactions in AdS. We contrast this map to known results using three-point Witten diagrams: the maps obtained via volume versus geodesic integrals differ. Despite these differences, we show how to decompose four-point exchange Witten diagrams in terms of geodesic diagrams, and we discuss the product expansion of local bulk fields in AdS.

A Solution to the Decompactification Problem in Chiral Heterotic Strings

Year: 2017
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We present a solution to the decompactification problem of gauge thresholds in chiral heterotic string theories with two large extra dimensions, where supersymmetry is spontaneously broken by the Scherk-Schwarz mechanism. Whenever the Kaluza-Klein scale is much lower than the string scale, the infinite towers of heavy states contribute non-trivially to the renormalisation of gauge couplings, which typically grow linearly with the large volume of the internal space and invalidate perturbation theory. We trace the origin of the decompactification problem to properties of the six dimensional theory obtained in the infinite volume limit and show that thresholds may instead exhibit logarithmic volume dependence and we provide the conditions for this to occur. We illustrate this mechanism with explicit string constructions where the decompactification problem does not occur.

description: Three new compounds including one furanone, one morpholinone and one tetrahydrofuran together with three known compounds were isolated from the broth extract of the marine-derived fungus Talaromyces sp. PSU-MF07. The structures of the isolated compounds were determined on the basis of spectroscopic methods. The relative configuration was assigned using NOEDIFF data whereas the absolute configurations were established by Mosher’s method, specific rotations and electronic circular dichroism (ECD) data. Some isolated compounds were tested for antimicrobial activity. Only known penioxalicin exhibited weak antibacterial activity against methicillin-resistant Staphylococcus aureus SK1 with an MIC value of 200 µg/mL.

description: WASP-127b is one of the lowest density planets discovered to date. With a sub-Saturn mass ($M_{\rm p}=0.18 \pm 0.02 M_J$) and super-Jupiter radius ($R_{\rm p}= 1.37 \pm 0.04 R_J$), it orbits a bright G5 star, which is about to leave the main-sequence. We aim to explore WASP-127b's atmosphere in order to retrieve its main atmospheric components, and to find hints for its intriguing inflation and evolutionary history. We used the ALFOSC spectrograph at the NOT telescope to observe a low resolution ($R\sim330$, seeing limited) long-slit spectroscopic time series during a planetary transit, and present here the first transmission spectrum for WASP-127b. We find the presence of a strong Rayleigh slope at blue wavelengths and a hint of Na absorption, although the quality of the data does not allow us to claim a detection. At redder wavelengths the absorption features of TiO and VO are the best explanation to fit the data. Although higher signal-to-noise ratio observations are needed to conclusively confirm the absorption features, WASP-127b seems to posses a cloud-free atmosphere and is one of the best targets to perform further characterization studies in the near future.

Forward-looking software solutions

description: Work Package 8 of PRACE-6IP has successfully initiated ten projects developing forward-looking software solutions. Eight of these projects started in April 2019 immediately, whilst two projects started in January 2020, after selection in a second call for proposals. This deliverable reports on the public release of prototype software by all projects. This early release of work-in-progress software guarantees software availability to the community, and provides the community with an opportunity to inspect, test, and provide feedback. All first phase projects have provided links to accessible code repositories such as GitHub, Bitbucket and similar. Projects typically use a modern development infrastructure, including version control, automated continuous integration (CI), and standard documentation formats. Testing includes correctness as well as performance. Whereas the readiness level of the projects differs, integration in user codes has taken place, first performance results have been included in this report, and certain codes have already become part of the procurement benchmarks of the EuroHPC Joint-Undertaking Pre-Exascale systems. The first phase of this work package can thus be considered successful.

description: Being a superluminous supernova (SLSN), PTF12dam can be explained by a $^{56}$Ni-powered model, a magnetar-powered model or an interaction model. We propose that PTF12dam is a pulsational pair instability supernova, where the outer envelope of a progenitor is ejected during the pulsations. Thus, it is powered by double energy source: radioactive decay of $^{56}$Ni and a radiative shock in a dense circumstellar medium. To describe multicolor light curves and spectra we use radiation hydrodynamics calculations of STELLA code. We found that light curves are well described in the model with 40M$_{\odot}$ ejecta and 20-40M$_{\odot}$ circumstellar medium. The ejected $^{56}$Ni mass is about 6M$_{\odot}$ which results from explosive nucleosynthesis with large explosion energy (2-3)$\cdot$10$^{52}$ ergs. In comparison with alternative scenarios of pair-instability supernova and magnetar-powered supernova, in interaction model all the observed main photometric characteristics are well reproduced: multicolor light curves, color temperatures, and photospheric velocities.

description: Diverse natural and synthetic furan derivatives have shown biological activity. Here, we describe the preparation of benzyl and arylethyl β-furanamides with OH or OMe aryl substituents by an adapted sustainable method from a furoic acid using methyl chloroformate. Symmetric and asymmetric β,β’-furanamides have instead been prepared using azabenzotriazole based catalyst (HATU). The products have been evaluated for their antimicrobial properties on Gram positive and Gram negative bacteria. Just a minimal not-significant activity has been observed in some derivatives.

description: Relation between tree density/ urbanization and mosquito populations in Houston, Texas. This was done using a GitHub program to map out tree density in Houston, Texas, and ArcGis to map out the mosquito populations dispersed across Houston, Texas. The GitHub code was used to measure the tree density and land cover in Houston Texas. This was possible thanks to a machine learning model program that took uploaded tree canopy pictures and predicted their height, density, and location. ArcGIS was used to create a base map of Houston, Texas that contained all mosquito data in that area from databases such as iNaturalist and GLOBE Mosquito Habitat Mapper.

description: (abridged) The dominant thermal mechanisms in the neutral interstellar medium, which acts as a star-forming gas reservoir, are uncertain in extremely metal-poor galaxies. Our objective is to identify the heating mechanisms in one such galaxy, IZw18, and assess the diagnostic value of fine-structure cooling lines. We also seek to constrain the mass of H$_2$, which, despite being an important catalyst and tracer of star formation, remains elusive in this object. Building on a previous photoionization model within a multi-sector topology, we provide additional constraints from the [CII] and [OI] lines and the dust mass recently measured with Herschel. The heating of the HI region appears to be mainly due to photoionization by radiation from a bright X-ray binary source, while photoelectric effect (PE) is negligible. The [CII] and [OI] lines imply an average X-ray luminosity of $4\times10^{40}$ erg s$^{-1}$, while the [NeV] upper limits bring strong constraints to the soft X-ray flux arising from the binary. A negligible amount of H$_2$ is predicted, but $\lesssim10^7$ M$_\odot$ of H$_2$ may be hidden in sufficiently dense clouds of order $\lesssim10$ pc in size. Regardless of the presence of significant amounts of H$_2$, [CII] and [OI] do not trace the so-called CO-dark gas, but the almost purely atomic medium. Although the [CII]+[OI]/TIR ratio is close to values found in more metal-rich sources, it cannot be safely used as a PE heating efficiency proxy. This ratio seems to be kept stable due to a correlation between the X-ray luminosity and the star-formation rate. We propose that X-ray heating is an important process in extremely metal-poor sources. The weak PE heating due to the low dust-to-gas ratio could be compensated for by the larger occurrence and power of X-ray binaries in low-metallicity galaxies. We speculate that X-ray heating may quench star formation.

description: Suspended optical microresonators are promising devices for on-chip photonic applications such as radio-frequency oscillators, optical frequency combs, and sensors. Scaling up these devices demand the capability to tune the optical resonances in an integrated manner. Here, we design and experimentally demonstrate integrated on-chip thermo-optic tuning of suspended microresonators by utilizing suspended wire bridges and microheaters. We demonstrate the ability to tune the resonance of a suspended microresonator in silicon nitride platform by 9.7 GHz using 5.3 mW of heater power. The loaded optical quality factor (QL ~ 92,000) stays constant throughout the detuning. We demonstrate the efficacy of our approach by completely turning on and off the optical coupling between two evanescently coupled suspended microresonators.

description: A new furanone analog, (E)-2-(8,9-dihydroxy-6,8-dimethyldec-4-en-2-yl)-met-hylfuran-3(2H)-one (1), together with six known compounds, including two diterpenoids (2 and 3), one butyrolactone (4) and three isocoumarins (5–7), were isolated from a deep-sea fungus, Purpureocillium sp. SCSIO 06693. Among them, compound 1 existed as two tautomeric forms (1a and 1b) differing in configuration of the furan ring. The chemical structures were elucidated by the basis of spectroscopic evidences, including HRESIMS, NMR and optical rotation. Isolated compounds were evaluated for their cytotoxic, antiviral, antibacterial, antioxidant, acetyl cholinesterase (AChE) and pancreatic lipase (PL) enzyme inhibitory activities. Biological evaluation results revealed that compound 4 showed modest antioxidant activity against DPPH with IC50 value of 72.03 μM. In addition, compounds 1–4 exhibited PL enzyme inhibitory activities.

description: We present the first results of a radio survey of 79 narrow-line Seyfert 1 (NLS1) carried out with the Karl G. Jansky Very Large Array (JVLA) at 5 GHz in A configuration aimed at studying the radio properties of these sources. We report the detection of extended emission in one object: Mrk 783. This is intriguing, since the radio-loudness parameter R of this object is close to the threshold between radio-quiet and radio-loud active galactic nuclei (AGN). The galaxy is one of the few NLS1 showing such an extended emission at z < 0.1. The radio emission is divided in a compact core component and an extended component, observed on both sides of the nucleus and extending from 14 kpc south-east to 12 kpc north-west. There is no sign of a collimated jet, and the shape of the extended component is similar to those of some Seyfert galaxies. The properties of the emission are compatible with a relic produced by the intermittent activity cycle of the AGN.

Topological Weyl and Node-Line Semimetals in Ferromagnetic Vanadium-Phosphorous-Oxide $β$-V$_2$OPO$_4$ Compound

description: We propose that the topological semimetal features can co-exist with ferromagnetic ground state in vanadium-phosphorous-oxide $β$-V$_2$OPO$_4$ compound from first-principles calculations. In this magnetic system with inversion symmetry, the direction of magnetization is able to manipulate the symmetric protected band structures from a node-line type to a Weyl one in the presence of spin-orbital-coupling. The node-line semimetal phase is protected by the mirror symmetry with the reflection-invariant plane perpendicular to magnetic order. Within mirror symmetry breaking due to the magnetization along other directions, the gapless node-line loop will degenerate to only one pair of Weyl points protected by the rotational symmetry along the magnetic axis, which are largely separated in momentum space. Such Weyl semimetal phase provides a nice candidate with the minimum number of Weyl points in a condensed matter system. The results of surface band calculations confirm the non-trivial topology of this proposed compound. This findings provide a realistic candidate for the investigation of topological semimetals with time-reversal symmetry breaking, particularly towards the realization of quantum anomalous Hall effect in Weyl semimetals.

An integrated approach to grey relational analysis, analytic hierarchy process and data envelopment analysis
Creators: name: Pakkar, Mohammad Sadegh
Publisher: name: arXiv
Year: 2017
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: Purpose: This paper aims to propose an integration of the analytic hierarchy process (AHP) and data envelopment analysis (DEA) methods in a multiattribute grey relational analysis (GRA) methodology in which the attribute weights are completely unknown and the attribute values take the form of fuzzy numbers. Design/methodology/approach: This research has been organized to proceed along the following steps: computing the grey relational coefficients for alternatives with respect to each attribute using a fuzzy GRA methodology. Grey relational coefficients provide the required (output) data for additive DEA models; computing the priority weights of attributes using the AHP method to impose weight bounds on attribute weights in additive DEA models; computing grey relational grades using a pair of additive DEA models to assess the performance of each alternative from the optimistic and pessimistic perspectives; and combining the optimistic and pessimistic grey relational grades using a compromise grade to assess the overall performance of each alternative. Findings: The proposed approach provides a more reasonable and encompassing measure of performance, based on which the overall ranking position of alternatives is obtained. An illustrated example of a nuclear waste dump site selection is used to highlight the usefulness of the proposed approach. Originality/value: This research is a step forward to overcome the current shortcomings in the weighting schemes of attributes in a fuzzy multiattribute GRA methodology. Keywords: Data envelopment analysis, Grey relational analysis, Analytic hierarchy process, Multiple attribute decision making, Fuzzy numbers, Weighting.

Combustion in thermonuclear supernova explosions

description: Type Ia supernovae are associated with thermonuclear explosions of white dwarf stars. Combustion processes convert material in nuclear reactions and release the energy required to explode the stars. At the same time, they produce the radioactive species that power radiation and give rise to the formation of the observables. Therefore, the physical mechanism of the combustion processes, as reviewed here, is the key to understand these astrophysical events. Theory establishes two distinct modes of propagation for combustion fronts: subsonic deflagrations and supersonic detonations. Both are assumed to play an important role in thermonuclear supernovae. The physical nature and theoretical models of deflagrations and detonations are discussed together with numerical implementations. A particular challenge arises due to the wide range of spatial scales involved in these phenomena. Neither the combustion waves nor their interaction with fluid flow and instabilities can be directly resolved in simulations. Substantial modeling effort is required to consistently capture such effects and the corresponding techniques are discussed in detail. They form the basis of modern multidimensional hydrodynamical simulations of thermonuclear supernova explosions. The problem of deflagration-to-detonation transitions in thermonuclear supernova explosions is briefly mentioned.

Spin-Pairing Correlations and Spin Polarization of Majorana Bound States in Two-Dimensional Topological Insulator Systems

description: We demonstrate that zero-energy Majorana bound state, in the ferromagnetic insulator (FI)-superconductor (SC) junction formed on the edge of two-dimensional topological insulator, exhibits three types of spin-triplet pairing correlations and its spin polarization direction is position independent in ferromagnetic insulator. When an electron is injected with a spin (anti-)parallel to this direction, equal-spin Andreev reflection exhibits the widest (narrowest) resonance peak. Similar behaviour is found when the coupling between two Majorana bound states in a FI-SC-FI junction is invoked, though an additional weak spin-singlet pairing correlation is generated. These signatures can readily facilitate the experimental detection of spin-triplet correlations and spin polarization of Majorana bound states.
