description: Two new compounds, dalpulanone (1) and 2-hydroxyisomucronustyrene (2), were isolated from the stems of Dalbergia stipulacea. Fourteen known compounds (3–16) were also isolated. The chemical structures of all isolated compounds were elucidated using spectroscopic methods, including 1D-NMR, 2D-NMR, MS and IR data. Compound 4 displayed the strongest antifungal activity against Pythium insidiosum and had higher activity than the amphotericin-B standard.

description: This paper considers the problem of modeling the light polarization that emerges from an astrophysical plasma composed of atoms whose excitation state is significantly influenced by the anisotropy of the incident radiation field. In particular, it highlights how radiative transfer simulations in three-dimensional models of the quiet solar atmosphere may help us to probe its thermal and magnetic structure, from the near equilibrium photosphere to the highly non-equilibrium upper chromosphere. The paper finishes with predictions concerning the amplitudes and magnetic sensitivities of the linear polarization signals produced by scattering processes in two transition region lines, which should encourage us to develop UV polarimeters for sounding rockets and space telescopes with the aim of opening up a new diagnostic window in astrophysics.

description: Trajectory-User Linking (TUL) is crucial for human mobility modeling by linking diferent trajectories to users with the exploration of complex mobility patterns. Existing works mainly rely on the recurrent neural framework to encode the temporal dependencies in trajectories, have fall short in capturing spatial-temporal global context for TUL prediction. To ill this gap, this work presents a new hierarchical spatio-temporal attention neural network, called AttnTUL, to jointly encode the local trajectory transitional patterns and global spatial dependencies for TUL. Speciically, our irst model component is built over the graph neural architecture to preserve the local and global context and enhance the representation paradigm of geographical regions and user trajectories. Additionally, a hierarchically structured attention network is designed to simultaneously encode the intra-trajectory and inter-trajectory dependencies, with the integration of the temporal attention mechanism and global elastic attentional encoder. Extensive experiments demonstrate the superiority of our AttnTUL method as compared to state-of-the-art baselines on various trajectory datasets. The source code of our model is available at https://github.com/Onedean/AttnTUL.

description: Two new flavonoids, 3, 3', 4' -Trihydroxy- 6, 7, 8 -trimethoxy flavone (1) and 3-Hydroxy-6, 7, 8, 3', 4'-pentamethoxy flavone (2) have been isolated from the methanol extract of Blumea eriantha DC. The structures of these compounds were determined on the basis of spectroscopic techniques such as IR, MS, 1 D, and 2 D NMR spectroscopy. The compounds (1) and (2) were tested for their anti-proliferative activity on NCI-H23 cell line. A standard drug Paclitaxel showed potent anti-proliferative effect (56%) at 100 nM concentration after 24 h treatment whereas compound (2) did not show any anti-proliferative effect. Only compound (1) showed significant reduction in cell viability at concentration 25773 nM (89%) and 257731 nM (68%) after 24 h when compared with 0.1% DMSO. The compound (1) showed significant but much lower reduction in cell viability as compared to the standard drug Paclitaxel.

description: Herpes simplex virus one is one of the most prevalent pathogens worldwide. Strains resistant to current treatment have been reported, so it is necessary to search for new antiviral molecules. The most common method to quantify antiviral activity from natural products is the plaque reduction assay, a technically demanding method. In order to provide a simple alternative to this method, we have established a procedure for viral quantification by qPCR, and coupled with a cytotoxicity evaluation system using resazurin. In this way, it is possible to obtain both the estimation of cytotoxicity and the antiviral activity simultaneously, allowing rapid screening of plant extracts. Ten out of twenty-eight Paraguayan medicinal plant extracts evaluated using this method showed antiviral activity, and the EC50, CC50, and SI values were calculated for each extract. Our experience supports the employment of the described method for a rapid identification of plant extracts with antiviral activity.

description: Derris reticulata (Leguminosae-Papilionoideae) has been used for the treatment of diabetes in Thai folk remedies. The phytochemical investigation of the wood of D. reticulata revealed the isolation of two new pyranoflavanones, 4′-methoxydereticulatin (1) and 2′′′-hydroxy,3′′′-ethoxylupinifolin (2), along with five known compounds namely lupinifolin (3), 2′′′,3′′′-dihydroxylupinifolin (4), genistein (5), lupeol (6), and β-sitosterol (7). Compounds 1–4 were selected for antibacterial assay using broth microdilution method, and displayed good activity against four out of five tested pathogenic bacterial strains, with MIC values ranging from 0.78 to 128 μg/mL. The result from spectrophotometric assay of α-glucosidase inhibition showed that 5 exhibited promising α-glucosidase inhibitory activity, compared with the positive control acarbose. Additionally, it was found that compounds 4 and 5 showed moderate DPPH and NO radicals scavenging activity. Modeling studies were also performed to suggest the interaction modes of compounds 3–5 in the α-glucosidase enzyme active site.
Effects of exercise intensity on anterior cerebral perfusion in prepubertal children
Creators: name: Simair, Ryan
Publisher: name: University of British Columbia
Year: 2017

description: Introduction: Although high intensity interval exercise (HIIE) has been well characterized in adults as providing superior systemic vascular adaptions compared to moderate intensity exercise (MIE), there is evidence that HIIE poses a challenge to cerebral hemodynamics. Only one study has investigated the child’s middle cerebral artery (MCA) response to incremental exercise to maximum, and we do not currently understand the cerebrovascular response to either HIIE or continuous MIE in the child. Methods: Nine children (aged 7-11 y; 5 girls) completed either HIIE (six 1-minute cycle ergometer sprints at 90% peak power (Wmax) with 1-minute recovery at 20% Wmax) or MIE (15 minutes at 44% Wmax on a cycle ergometer, matched to HIIE for external work). MCA velocity (MCAv), partial pressure of end tidal carbon dioxide (PETCO₂) and mean arterial pressure (MAP) were measured at baseline, immediately post-, 30 minutes post- and 60 minutes post-exercise. MCAv was also continuously recorded throughout exercise. A repeated measures ANOVA was used to compare changes from baseline across the time-points and between the exercise conditions. Results: The MCAv peaked during the first two minutes in both HIIE (minute 1: +12.10±2.70% & minute 2: +12.65±6.20%; p’s<0.05) and MIE (minute 1: +7.46±5.37% & minute 2: +9.78±6.40%; p’s<0.05). In HIIE, MCAv significantly decreased below baseline for the final 3 sprints (P<0.05), oscillating back to baseline for the remaining rest intervals. In MIE, the MCAv returned to baseline after the 4th minute of exercise, where it remained under exercise cessation. The cerebrovascular resistance index (CVRi) significantly increased (P’s<0.05) during the final minute of both MIE (+7.0±6.70%) and HIIE (+21.5±7.60%), with a significant difference between intensities (P<0.05). Immediately post HIIE, the MCAv uncoupled from PETCO₂, whereas immediately post MIE the MCAv and PETCO₂ remained at baseline values. Discussion: The decline in MCAv during the latter half of both HIIE and MIE may reflect adequate cerebral oxygenation because of the elevated MCAv baseline values in children compared to adults. The increase in CVRi in the final minute of HIIE is likely driven via hyperventilatory hypocapnia. Finally, it appears that PETCO₂ has a diminished regulatory effect over MCAv in children following HIIE.

description: Herschel-HIFI observations of high-J lines (up to J_u=10) of 12CO, 13CO and C18O are presented toward three deeply embedded low-mass protostars in NGC1333. The observations show several energetic components including shocked and quiescent gas. Radiative transfer models are used to quantify the C18O envelope abundance which require a jump in the abundance at an evaporation temperature, T_ev ~25 K, providing new direct evidence of a CO ice evaporation zone around protostars. The abundance in the outermost part of the envelope, X_0, is within the canonical value of 2x10^-4; however the inner abundance, X_in, is found around a factor of 3-5 lower than X_0.

Ecological niche divergence and evolution in western North American monkeyflowers
Creators: name: Li, Qin
Publisher: name: University of British Columbia
Year: 2018

description: The ecological niche is an essential concept for studies in ecology, evolution and biogeography. Geographic distributions are largely determined by species’ ecological niches. In turn, niches evolve via selection stemming from where species occur, which has implications for coexistence and the breadth of environmental tolerance. With modern comparative methods, we can improve our understanding of interactions among niche, range and diversification across spatial scales. To select variables for quantifying niche properties, I first applied generalized linear models with occurrence data of 71 western North American monkeyflowers (Mimulus sensu lato). Then I evaluated the relative importance of four bioclimatic variables by ranking them based on the magnitudes of model-averaged regression coefficients. Thus three out of four bioclimatic variables were identified as important predictors in determining geographic distributions of Mimulus species, while one variables was negligible due to its small effect. To determine how geographic overlap affects niche divergence, I quantified niche divergence for 16 closely related Mimulus species pairs. I found that macrohabitat niche divergence decreased with increasing range overlap, consistent with environmental filtering operating in sympatry and divergent selection operating in allopatry. For species pairs with partially overlapping ranges, greater microhabitat niche divergence was found in sympatry, consistent with competition driving divergence where species interact. Phylogenetic distance was positively related to niche divergence for two macrohabitat axes but negatively related for one microhabitat axis. This suggests increasing coarse-scale niche similarity with increasing sympatry following allopatric speciation, while greater local-scale niche divergence accumulates through time. Given differences in evolutionarily lability of niche axes across spatial scales, I next examined evolutionary trends in niche breadth. For 82 Mimulus species, I converted niche breadths into binary states, generalist or specialist. Then I tested whether niche breadth affected diversification rate and explored evolutionary transitions. My results showed higher diversification rates for generalists and weak generalist-to-specialist trends for three bioclimatic variables, but higher diversification rates for specialists and weak specialist-to-generalist trends for two microhabitat variables. Together, these results suggest that ecology plays an essential role in diversification processes, but underlying mechanisms might differ across spatial scales.

description: SrAs$_3$ is a unique nodal-line semimetal that contains only a single nodal ring in the Brillouin zone, uninterrupted by any trivial bands near the Fermi energy. We performed axis-resolved optical reflection measurements on SrAs$_3$ and observed that the optical conductivity exhibits flat absorption up to 129 meV in both the radial and axial directions, confirming the robustness of the universal power-law behavior of the nodal ring. Furthermore, in conjunction with model and first-principles calculations, the axis-resolved optical conductivity unveiled fundamental properties beyond the flat absorption, including the overlap energy of the topological bands, the spin-orbit coupling gap along the nodal ring, and the geometric properties of the nodal ring such as the average ring radius, ring ellipticity, and velocity anisotropy. In addition, our temperature-dependent measurements revealed a spectral weight transfer between intraband and interband transitions, indicating a possible violation of the optical sum rule within the measured energy range.

description: We systematically investigate the prospects of testing new physics with tau sensitive near detectors at neutrino oscillation facilities. For neutrino beams from pion decay, from the decay of radiative ions, as well as from the decays of muons in a storage ring at a neutrino factory, we discuss which effective operators can lead to new physics effects. Furthermore, we discuss the present bounds on such operators set by other experimental data currently available. For operators with two leptons and two quarks we present the first complete analysis including all relevant operators simultaneously and performing a Markov Chain Monte Carlo fit to the data. We find that these effects can induce tau neutrino appearance probabilities as large as O(10^{-4}), which are within reach of forthcoming experiments. We highlight to which kind of new physics a tau sensitive near detector would be most sensitive.

description: In decision-making methods, it is common to assume that the experts are honest and professional. However, this is not the case when one or more experts in the group decision making framework, such as the group analytic hierarchy process (GAHP), try to manipulate results in their favor. The aim of this paper is to introduce two heuristics in the GAHP, setting allowing to detect the manipulators and minimize their effect on the group consensus by diminishing their weights. The first heuristic is based on the assumption that manipulators will provide judgments which can be considered outliers with respect to those of the rest of the experts in the group. The second heuristic assumes that dishonest judgments are less consistent than the average consistency of the group. Both approaches are illustrated with numerical examples and simulations.

Macroscopic form of the first law of thermodynamics for an adiabatically evolving non-singular self-gravitating fluid

description: We emphasize that the pressure related work appearing in a general relativistic first law of thermodynamics should involve {\em proper volume element} rather than coordinate volume element. This point is highlighted by considering both local energy momentum conservation equation as well as particle number conservation equation. It is also emphasized that we are considering here a {\em non-singular} fluid governed by purely classical general relativity. Therefore, we are not considering here any semi-classical or quantum gravity which apparently suggests thermodynamical properties even for a (singular) black hole. Having made such a clarification, we formulate a global first law of thermodynamics for an adiabatically evolving spherical perfect fluid. It may be verified that such a global first law of thermodynamics, {\em for a non-singular fluid}, has not been formulated earlier.

description: The control of a superconducting current via the application of a gate voltage has been recently demonstrated in a variety of superconducting devices. Although the mechanism underlying this gate-controlled supercurrent (GCS) effect remains under debate, the GCS effect has raised great interest for the development of the superconducting equivalent of conventional metaloxide semiconductor electronics. To date, however, the GCS effect has been mostly observed in superconducting devices made by additive patterning. Here, we show that devices made by subtractive patterning show a systematic absence of the GCS effect. Doing a microstructural analysis of these devices and comparing them to devices made by additive patterning, where we observe a GCS, we identify some material and physical parameters that are crucial for the observation of a GCS. We also show that some of the mechanisms proposed to explain the origin of the GCS effect are not universally relevant.

description: We propose a description of pairing properties in finite systems within the canonical and microcanonical ensembles. The approach is derived by solving the BCS and self-consistent quasiparticle random-phase approximation with the Lipkin-Nogami particle-number projection at zero temperature. The obtained eigenvalues are embedded into the canonical and microcanonical ensembles. The results obtained are found in quite good agreement with the exact solutions of the doubly-folded equidistant multilevel pairing model as well as the experimental data for $^{56}$Fe nucleus. The merit of the present approach resides in its simplicity and its application to a wider range of particle number, where the exact solution is impracticable.

description: The standard model (SM) of particle physics represents a theoretical paradigm for the description of the fundamental forces of nature. Despite its broad applicability, the SM does not enable the description of all physically possible events. The detection of events that cannot be described by the SM, which are typically referred to as anomalous, and the related potential discovery of exotic physical phenomena is a non-trivial task. The challenge becomes even greater with next-generation colliders that will produce even more events with additional levels of complexity. The additional data complexity motivates the search for unsupervised anomaly detection methods that do not require prior knowledge about the underlying models. In this work, we develop such a technique. More explicitly, we employ a quantum generative adversarial network to identify anomalous events. The method learns the background distribution from SM data and, then, determines whether a given event is characteristic for the learned background distribution. The proposed quantum-powered anomaly detection strategy is tested on proof-of-principle examples using numerical simulations and IBM Quantum processors. We find that the quantum generative techniques using ten times fewer training data samples can yield comparable accuracy to the classical counterpart for the detection of the Graviton and Higgs particles. Additionally, we empirically compute the capacity of the quantum model and observe an improved expressivity compared to its classical counterpart.

description: We calculate energy and momentum of a spherically symmetric dilaton frame using the gravitational energy-momentum 3-form within the tetrad formulation of general relativity (GR). The frame we use is characterized by an arbitrary function $Υ$ with the help of which all the previously found solutions can be reproduced. We show how the effect of inertia {\it (which is mainly reproduced from $Υ$)} makes the total energy and momentum always different from the well known result when we use the Riemannian connection ${{\widetilde Γ}_α}^β$. On the other hand, when use is made of the covariant formulation of teleparallel gravity, which implies to take into account the pure gauge connection, teleparallel gravity always yields the physically relevant result for the energy and momentum.

description: In this paper we introduce a design for an optical topological cluster state computer constructed exclusively from a single quantum component. Unlike previous efforts we eliminate the need for on demand, high fidelity photon sources and detectors and replace them with the same device utilised to create photon/photon entanglement. This introduces highly probabilistic elements into the optical architecture while maintaining complete specificity of the structure and operation for a large scale computer. Photons in this system are continually recycled back into the preparation network, allowing for a arbitrarily deep 3D cluster to be prepared using a comparatively small number of photonic qubits and consequently the elimination of high frequency, deterministic photon sources.

description: We continue our study of the global properties of the z=2 Schroedinger space-time. In particular, we provide a codimension 2 isometric embedding which naturally gives rise to the previously introduced global coordinates. Furthermore, we study the causal structure by probing the space-time with point particles as well as with scalar fields. We show that, even though there is no global time function in the technical sense (Schroedinger space-time being non-distinguishing), the time coordinate of the global Schroedinger coordinate system is, in a precise way, the closest one can get to having such a time function. In spite of this and the corresponding strongly Galilean and almost pathological causal structure of this space-time, it is nevertheless possible to define a Hilbert space of normalisable scalar modes with a well-defined time-evolution. We also discuss how the Galilean causal structure is reflected and encoded in the scalar Wightman functions and the bulk-to-bulk propagator.

description: Edible flowers consumption has increased in recent years due to their rich content of healthy phytochemicals. The aim of this study was to analyse the chemical profile of Cucurbita pepo L. flowers, and to explore their antioxidant and hypoglycaemic properties. Moreover, in order to assess in vivo effects, biochemical analysis, Reactive Oxygen Metabolites (d-ROMs) and Biological Antioxidant Potential (BAP) tests were performed on mice serum. High Performance Liquid Chromatography-Diode Array Detection (HPLC-DAD) analyses revealed the presence of (+)-catechin, (−)-epicatechin, rutin, and syringic acid as main constituents. 2,2′-Azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and Ferric Reducing Antioxidant Power (FRAP) tests showed interesting results. The extract exhibited the strongest inhibitory effect on α-glucosidase (IC50 of 144.77 μg/mL). In vivo results confirmed the hypoglycaemic effects, also affecting lipid metabolism but did not revealed benefits on ROS production. These results may add some information supporting the use of C. pepo flowers as functional foods and/or nutraceuticals.

description: Phytochemical investigation on the soluble fractions of n-hexane and dichloromethane of methanolic leaves extract of the Callicarpa maingayi K. & G. led to the isolation of three triterpenoids [euscaphic acid (1), arjunic acid (2), and ursolic acid (3)] together with two flavones [apigenin (4) and acacetin (5)], two phytosterols [stigmasterol 3-O-β-glycopyranoside (6) and sitosterol 3-O-β-glycopyranoside (7)], and a fatty acid [n-hexacosanoic acid (8)]. Six (6) compounds (1, 2, 3, 4, 5, and 8) are reported for the first time from this species. Their structures were elucidated and identified by extensive NMR techniques, GC-MS and comparison with the previously reported literature. Compound 3 was found to displayed good inhibition against acetylcholinesterase with an IC50 value of 21.5 ± 0.022 μM, while 1 and 2 exhibited pronounced α-glucosidase inhibitory activity with IC50 values of 22.4 ± 0.016 μM and 24.9 ± 0.012 μM, respectively.

description: Comet 67P/Churyumov-Gerasimenko is the main target of ESA's Rosetta mission and will be encountered in May 2014. As the spacecraft shall be in orbit the comet nucleus before and after release of the lander {\it Philae}, it is necessary necessary to know the conditions in the coma. Study the dust environment, including the dust production rate and its variations along its preperihelion orbit. The comet was observed during its approach to the Sun on four epochs between early-June 2008 and mid-January 2009, over a large range of heliocentric distances that will be covered by the mission in 2014. An anomalous enhancement of the coma dust density was measured towards the comet nucleus. The scalelength of this enhancement increased with decreasing heliocentric distance of the comet. This is interpreted as a result of an unusually slow expansion of the dust coma. Assuming a spherical symmetric coma, the average amount of dust as well as its ejection velocity have been derived. The latter increases exponentially with decreasing heliocentric distance (\rh), ranging from about 1 m/s at 3 AU to about 25-35 m/s at 1.4 AU. Based on these results we describe the dust environment at those nucleocentric distances at which the spacecraft will presumably be in orbit. Astronomy and Astrophysics, in press

description: Acca sellowiana is an evergreen plant that produces edible fruit whit high nutritional properties, and also contains clinically relevant bioactive compounds, including polyphenols and essential oils. Numerous biological activities were demonstrated for A. sellowiana fruits: antifungal and antitumoral and anti-oxidant. It was also showed a strong antibacterial activity against Gram-positive and Gram-negative bacteria. Fruit are generally considered recalcitrant plant tissues for the difficulty to obtain high quality protein due to a low protein content and the presence of interfering substances. For this reason, the objective of the present work was obtain high quantity of protein extract, to determine the location in the fruit of the molecules responsible for the antibacterial activity, separate them according to molecular weight, test their thermo resistance, study the timing of action, isolate the protein fraction having activity and hypothesise a mechanism of action directed against bacterial membranes.

description: The forest related conflicts has not been very often used as a research topic in Croatia. This paper presents results from two case studies conducted in Nature Parks» Kopa~kirit« and »Velebit«. The aim of the study was to explore conflicts between forestry and nature protection on management level. 
The main research questions were raised: 

(a) What causes conflicts?; 
(b)What are the attitudes of conflict actors towards conflicts as a phenomenon and towards other conflict parties?; 
(c) What was undertaken to manage conflicts and was it successful? and 
(d) How the conflicts and CM influence forest policy development process?
OEMC project use case: Forest management and tracking tools for Croatia

description: OpenGeoHub has worked closely with the National Parks of Croatia (National Nature Park Papuk), on getting local on-ground data and then using it to train models to compare protected and managed forest over the last 25yrs. Pauk sees an opportunity to build and share data with other stakeholders interested in such data — for example state companies such as Croatian Forest (https://www.hrsume.hr/) or Croatian Waters (https://voda.hr/hr). 
Stakeholder needs: 

Papuk is looking for support for using EU-wide and national data products and tools for monitoring / tracking status of resources. There are often overlaps in how the forest resources are managed (Nature Park vs Croatian Forests) and geospatial tools with info for the past 25+ years could help improve decisions (multicriteria decision systems),
Papuk is not aware of all Copernicus Land Monitoring Services products and all Landsat-based products — where to find the data and how to access it in QGIS?
Staff at Papuk are looking for an open source application to be able to collect ground data (on mobile phones) that can then be loaded and used directly in a GIS,
Implementation steps include: 

OpenGeoHub has visited Papuk, provided training and helped improve forest management and tracking primarily based on EO data processed independently by OEMC consortium,
Install local copy of G3W suite and import all data (i.e. build a local prototype webGIS for PP Papuk); provide training on how to use MerginMaps.com app on mobile phones to quickly collect ground data and display in QGIS,
Time-resolved fluorescent chirality sensing and imaging of malate in aqueous solution

subject: 540 Chemie

description: Chiral discrimination of malates in aqueous solutions at near-neutral pH is achieved through fluorescence measurement and imaging using the europium–tetracycline complex (EuTc) as a fluorescent probe. The method is based on the significantly different fluorescence properties of the ternary complexes (Eu–Tc–malate) formed between EuTc and the enantiomeric malates. The enantiomeric excess (ee) of chiral malates can be quantified by both steady-state and time-resolved fluorescence, using either a conventional fluorescence microplate reader or fluorescence imaging. It offers a facile and sensitive method for high-throughput chiral discrimination.

description: This paper presents our recent research on integrating artificial emotional intelligence in a social robot (Ryan) and studies the robot's effectiveness in engaging older adults. Ryan is a socially assistive robot designed to provide companionship for older adults with depression and dementia through conversation. We used two versions of Ryan for our study, empathic and non-empathic. The empathic Ryan utilizes a multimodal emotion recognition algorithm and a multimodal emotion expression system. Using different input modalities for emotion, i.e. facial expression and speech sentiment, the empathic Ryan detects users' emotional state and utilizes an affective dialogue manager to generate a response. On the other hand, the non-empathic Ryan lacks facial expression and uses scripted dialogues that do not factor in the users' emotional state. We studied these two versions of Ryan with 10 older adults living in a senior care facility. The statistically significant improvement in the users' reported face-scale mood measurement indicates an overall positive effect from the interaction with both the empathic and non-empathic versions of Ryan. However, the number of spoken words measurement and the exit survey analysis suggest that the users perceive the empathic Ryan as more engaging and likable.
