description: A preliminary research on the marine fungus Fusarium sp. XBB-9 resulted in a pair of novel bisindole alkaloid enantiomers, (+)- and (–)-fusaspoid A (1a/1b) and 12 diverse compounds. One strain many compound (OSMAC) method was used to enhance as many biosynthetic pathways as possible. The structures of the compounds were elucidated by spectroscopic analysis, and the absolute configuration of 1a was determined by X-ray single-crystal diffraction analysis. Compounds 1a and 1b were tested for cytotoxic activity against HCT-15, RKO cell lines, but were inactive. Compounds 1a and 1b were the first example of bisindole alkaloids isolated from fungus Fusarium sp. XBB-9.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A class of curved spacetimes with global parabolic isometries (GPI) is introduced. These isometries have fixed point sets on two-dimensional null surfaces which can be interpreted as worldsheets of massless cosmic strings. Back reaction effects of the strings in such spacetimes can be described exactly, in terms of a nontrivial holonomy at the worldsheet. We show that the GPI spacetimes are type $N$ geometries of the Petrov classification. We describe a number of features of these spacetimes, including properties of Killing horizons associated to GPI. As an example, we consider a circular massless cosmic string in the de Sitter universe and present the metric in new coordinates centered at the string worldsheet.

description: Water supply instability is one of the main risks faced by irrigation districts and farmers. Water procurement decision optimisation is essential in order to increase supply reliability and reduce costs. Water markets, such as spot purchases or water supply option contracts, can make this decision process more ﬂexible. We analyse the potential interest in an option contract for an irrigation district that has access to several water sources. We apply a stochastic recursive mathematical programming model to simulate the water procurement decisions of an irrigation district’s board operating in a context of water supply uncertainty in south-eastern Spain. We analyse what role diﬀerent option contracts could play in securing its water supply. Results suggest that the irrigation district would be willing to accept the proposed option contract in most cases subject to realistic values of the option contract ﬁnancial terms. Of nine diﬀerent water sources, desalination and the option contract are the main substitutes, where the use of either depends on the contract parameters. The contract premium and optioned volume are the variables that have a greater impact on the irrigation district’s decisions.

description: Mycobacteria are a unique group of microorganisms. They are characterised by exceptional adaptability and durability. They are capable of colonisation and survival even in very unfavourable conditions. In addition to the well-known obligate human pathogens, Mycobacterium tuberculosis and M. leprae, more than 200 other species have been described. Most of them form a natural part of the microflora of the external environment and thrive in aquatic and soil environments especially. For many of the mycobacterial species associated with human disease, their natural source has not yet been identified. From an ecological point of view, mycobacteria are saprophytes, and their application in human and animal diseases is opportunistic. Most cases of human disease from saprophytic mycobacteria occur in immunocompromised individuals. This adaptability and resilience to environmental pressures makes treatment of mycobacterial diseases (most often sapronoses and less often zoonoses) and permanent eradication of mycobacteria from the environment very difficult. Saprophytic mycobacterial diseases (sapronoses) are chronic and recurrent due to the fact of repeated endogenous or exogenous re-exposure. Therefore, knowledge regarding their occurrence in soil and dust would aid in the prevention of saprophytic mycobacterioses. In conjunction, their presence and ecological significance in the environment can be revealed.

description: Background: Onchocerciasis is a neglected tropical filarial disease transmitted by the bites of blackflies, causing blindness and severe skin lesions. The change in focus for onchocerciasis management from control to elimination requires thorough mapping of pre-control endemicity to identify areas requiring interventions and to monitor progress. Onchocerca volvulus nodule prevalence in sub-Saharan Africa is spatially continuous and heterogeneous, and highly endemic areas may contribute to transmission in areas of low endemicity or vice-versa. Ethiopia is one such onchocerciasis-endemic country with heterogeneous O. volvulus nodule prevalence, and many districts are still unmapped despite their potential for onchocerciasis transmission. Methodology/Principle findings: A Bayesian geostatistical model was fitted for retrospective pre-intervention nodule prevalence data collected from 916 unique sites and 35,077 people across Ethiopia. We used multiple environmental, socio-demographic, and climate variables to estimate the pre-inter-vention prevalence of O. volvulus nodules across Ethiopia and to explore their relationship with prevalence. Prevalence was high in southern and northwestern Ethiopia and low in Ethiopia’s central and eastern parts. Distance to the nearest river (RR: 0.9850, 95% BCI: 0.9751–0.995), precipitation seasonality (RR: 0.9837, 95% BCI: 0.9681–0.9995), and flow accumulation (RR: 0.9586, 95% BCI: 0.9321–0.9816) were negatively associated with O. volvulus nodule prevalence, while soil moisture (RR: 1.0218, 95% BCI: 1.0135–1.0302) was positively associated. The model estimated the number of pre-intervention cases of O. volvulus nodules in Ethiopia to be around 6.48 million (95% BCI: 3.53–13.04 million). Conclusions/Significance: Nodule prevalence distribution was correlated with habitat suitability for vector breeding and associated biting behavior. The modeled pre-intervention prevalence can be used as a guide for determining priorities for elimination mapping in regions of Ethiopia that are cur-rently unmapped, most of which have comparatively low infection prevalence.

Η κοινωνική σύγκριση και η αντικειμενοποίηση των γυναικών στο Instagram συμβάλλουν αρνητικά στην εικόνα και τον έλεγχο του σώματος τους. Στόχος της παρούσας έρευνας είναι η μελέτη του νοήματος που αποδίδουν στις ολόσωμες φωτογραφίες τους χρήστριες δεκαοχτώ ετών και των επιδράσεων τους. Για τους σκοπούς της έρευνας, πραγματοποιήθηκαν δώδεκα συνεντεύξεις γυναικών χρηστών, οι οποίες αναλύθηκαν με την μέθοδο της θεματικής ανάλυσης. Από την ανάλυση, αναδύθηκαν τα θέματα του εξιδανικευμένου και αυθεντικού εαυτού, της κοινωνικής αποδοχής και των ερωτικών σχέσεων, τα οποία αλληλεπιδρούν εντασσόμενα στο ευρύτερο θέμα του μεταφεμινισμού. Οι χρήστριες μέσα από την ανάρτηση ολόσωμων φωτογραφιών μοιράζονται αυθεντικές και εξιδανικευμένες πτυχές του εαυτού τους αποζητώντας την κοινωνική αποδοχή και την δημιουργία νέων ερωτικών σχέσεων, ενώ η διαδικτυακή εικόνα σώματος φαίνεται να επηρεάζει την αυτοπεποίθηση, τα συναισθήματα και τις ερωτικές σχέσεις τους.

description: Instagram is a new field in the research of self-presentation and body image of young women. Using Instagram, women develop socially accepted identities and compare themselves with other users. Social comparison and objectification of women on Instagram contribute in a negative way to their body image and body control. The research goals of the present study are to investigate the meaning eighteen year old women attribute to their body images and their implications on their lives. For the research purposes, twelve interviews of female Instagram users were conducted and analysed with thematic analysis. The analysis revealed the themes of idealised and authentic self, social acceptance and love affairs, which all interact within the bigger theme of metafeminism. The female users share through their body images authentic and idealised versions of themselves, seeking social acceptance and new love affairs, while online body image seems to influence their self confidence, feelings and love affairs. Although the sample size was small, it revealed the negative effects of Instagram use on young women and the need for future research to investigate the effectiveness of psychο-educational programmes on self-empowerment of young women.

description: Global models of agricultural trade have a long and distinguished history. The introduction of the GTAP data base and modeling project represented a significant advance forward as it put modelers and trade policy analysts on common ground. After an initial generation of GTAP based modeling of agricultural trade policy using the standard modeling framework, individual researchers have begun introducing agricultural specificity into the standard modeling framework in order to better capture the particular features of the agricultural economy pertinent to their research questions. This technical paper follows in that same tradition by reviewing important linkages between international trade and the farm and food economy and introducing them into the standard GTAP modeling framework, offering a special purpose version of the model nicknamed GTAP-AGR. We introduce this agricultural specificity by introducing new behavioral relationships into the standard GTAP framework. We focus particular attention on the factor markets, which play a critical role in determining the incidence of producer subsidies. This includes modifying both the factor supply and derived demand equations. We also modify the specification of consumer demand, assuming separability of food from non-food commodities. Finally, we introduce the important substitution possibilities amongst feedstuffs used in the livestock sector. Where possible we support these new behavioral relationships with literature-based estimates of both the mean and standard deviation of behavioral parameters. The express purpose of this is to support systematic sensitivity analysis with respect to policy reform scenarios performed with GTAP-AGR. In addition to documenting these extensions to the standard modeling framework, the paper has an additional goal, and that is to gauge the performance of the GTAP-AGR model and how it differs from the standard GTAP framework. We do this primarily by comparing the farm level supply and demand response in terms of policy incidence for the two frameworks. In addition, we evaluate the ability of both models to reproduce observed price volatility in an effort to validate the performance of these models. Finally, we evaluate the results of the two models in a side-by-side comparison of results from full liberalization of agricultural and non-agricultural support.

description: This paper describes the GTAP Land Use Data Base designed to support integrated assessments of the potential for greenhouse gas mitigation. It disaggregates land use by agro-ecological zone (AEZ). To do so, it draws upon global land cover data bases, as well as state-of-the-art definition of AEZs from the FAO and IIASA. Agro-ecological zoning segments a parcel of land into smaller units according to agro-ecological characteristics, including: precipitation, temperature, soil type, terrain conditions, etc. Each zone has a similar combination of constraints and potential for land use. In the GTAP-AEZ Data Base, there are 18 AEZs, covering six different lengths of growing period spread over three different climatic zones. Land using activities include crop production, livestock raising, and forestry. In so doing, this extension of the standard GTAP Data Base permits a much more refined characterization of the potential for shifting land use amongst these different activities. When combined with information on greenhouse gas emissions, this data base permits economists interested in integrated assessment of climate change to better assess the role of land use change in greenhouse gases mitigation strategies.

description: Transportation, wholesaling, and retailing activities are a significant segment of economic activity in many economies. The magnitude of these activities can vary greatly between products, users, and regions. However, in most applied general equilibrium (AGE) analyses, these marketing activities are not tied to specific commodities. This paper develops a model framework and database that incorporates domestic marketing margins on domestic and imported goods going to final demand or used as intermediate inputs, and margins on exports, into the standard GTAP Model. The effects of incorporating domestic marketing activities into an AGE model are illustrated by comparing the results of the standard GTAP Model to the new GTAP-M Model for several different technological change scenarios. The comparison yields two main results. First, tying the domestic marketing activities to specific commodities changes the degree of price transmission from producers to users, compared to a model that does not include margin activities explicitly. The second main result is that the magnitude of the elasticity of substitution between commodities and the composite marketing activity is very important. Allowing variable margins creates a new source of demand-responsiveness for commodities which can significantly alter the results of policy simulations.

description: Social distancing is an important component of the response to the novel Coronavirus (COVID-19) pandemic. Minimizing social interactions and travel reduces the rate at which the infection spreads, and "flattens the curve" such that the medical system can better treat infected individuals. However, it remains unclear how the public will respond to these policies. This paper presents the Twitter Social Mobility Index, a measure of social distancing and travel derived from Twitter data. We use public geolocated Twitter data to measure how much a user travels in a given week. We find a large reduction in travel in the United States after the implementation of social distancing policies, with larger reductions in states that were early adopters and smaller changes in states without policies. Our findings are presented on http://socialmobility.covid19dataresources.org and we will continue to update our analysis during the pandemic.

description: This paper develops a mathematical programming model to simultaneously estimate re-export markups and reconcile bilateral trade statistics between China, Hong Kong, and their trading partners. The model is applied to sector level trade flows to resolve discrepant reporting in an efficient manner. Adjustments in trade flows are based upon statistical reportersâ€™ reliability information. The program is implemented in GAMS and retains many desirable theoretical and empirical properties. Estimates are used for generating trade flows and markups for Hong Kongâ€™s re-exports used in the forthcoming version 7 GTAP database. The modelâ€™s flexibility has potential for expanded use in other regions where re-exports and associated markup cause discrepant trade flows.

description: Wolfgang Rump showed that there is a one-to-one correspondence between nondegenerate involutive set-theoretic solutions of the Yang-Baxter equation and binary algebras in which all left translations $L_x$ are bijections, the squaring map is a bijection, and the identity $(xy)(xz) = (yx)(yz)$ holds. We call these algebras \emph{rumples} in analogy with quandles, another class of binary algebras giving solutions of the Yang-Baxter equation. We focus on latin rumples, that is, on rumples in which all right translations are bijections as well. We prove that an affine latin rumple of order $n$ exists if and only if $n=p_1^{p_1 k_1}\cdots p_m^{p_m k_m}$ for some distinct primes $p_i$ and positive integers $k_i$. A large class of affine solutions is obtained from nonsingular near-circulant matrices $A$, $B$ satisfying $[A,B]=A^2$. We characterize affine latin rumples as those latin rumples for which the displacement group generated by $L_x L_y\inv$ is abelian and normal in the group generated by all translations. We develop the extension theory of rumples sufficiently to obtain examples of latin rumples that are not affine, not even isotopic to a group. Finally, we investigate latin rumples in which the dual identity $(zx)(yx) = (zy)(xy)$ holds as well, and we show, among other results, that the generators $L_x L_y\inv$ of their displacement group have order dividing four.

This is done by assuming that such systems can be described by a superposition of the ground and first excited states of the master equation. We corroborate our results numerically for the metastable states of a two-dimensional Ising model.

description: Field pea is the most commonly grown temperate pulse crop, with close to 15 million tons produced globally in 2020. Varieties improved through breeding are important to ensure ongoing improvements in yield and disease resistance. Genomic selection (GS) is a modern breeding approach that could substantially improve the rate of genetic gain for grain yield, and its deployment depends on the prediction accuracy (PA) that can be achieved. In our study, four yield trials representing breeding lines' advancement stages of the breeding program (S0, S1, S2, and S3) were assessed with grain yield, aerial high-throughput phenotyping (normalized difference vegetation index, NDVI), and bacterial blight disease scores (BBSC). Low-to-moderate broad-sense heritability (0.31–0.71) and narrow-sense heritability (0.13–0.71) were observed, as the estimated additive and non-additive genetic components for the three traits varied with the different models fitted. The genetic correlations among the three traits were high, particularly in the S0–S2 stages. NDVI and BBSC were combined to investigate the PA for grain yield by univariate and multivariate GS models, and multivariate models showed higher PA than univariate models in both cross-validation and forward prediction methods. A 6–50% improvement in PA was achieved when multivariate models were deployed. The highest PA was indicated in the forward prediction scenario when the training population consisted of early generation breeding stages with the multivariate models. Both NDVI and BBSC are commonly used traits that could be measured in the early growth stage; however, our study suggested that NDVI is a more useful trait to predict grain yield with high accuracy in the field pea breeding program, especially in diseased trials, through its incorporation into multivariate models.

description: Geodesics of both lightrays and timelike particles with nonzero mass are deflected in a gravitational field. In this work we apply the perturbative method developed in Ref. \cite{Jia:2020dap} to compute the deflection angle of both null and timelike rays in the weak field limit for four spacetimes. We obtained the deflection angles for the Bardeen spacetime to the eleventh order of $m/b$ where $m$ is the ADM mass and $b$ is the impact parameter, and for the Hayward, Janis-Newman-Winicour and Einstein-Born-Infeld spacetimes to the ninth, seventh and eleventh order respectively. The effect of the impact parameter $b$, velocity $v$ and spacetime parameters on the deflection angle are analyzed in each of the four spacetimes. It is found that in general, the perturbative deflection angle depends on and only on the asymptotic behavior of the metric functions, and in an order-correlated way. Moreover, it is shown that although these deflection angles are calculated in the large $b/m$ limit, their minimal valid $b$ can be as small as a few $m$'s as long as the order is high enough. At these impact parameters, the deflection angle itself is also found large. As velocity decreases, the deflection angle in all spacetime studied increases. For a given $b$, if the spacetime parameters allows a critical velocity $v_c$, then the perturbative deflection angle will deviate from its true value as $v$ decreases to $v_c$. It is also found that if the variation of spacetime parameters can only change the spacetime qualitatively at small but not large radius, then these spacetime parameter will not cause a qualitative change of the deflection angle, although its value is still quantitatively affected. The application and possible extension of the work are discussed.

description: In plant cells, mitochondria are ideally positioned to sense and balance changes in energy metabolism in response to changing environmental conditions. Retrograde signaling from mitochondria to the nucleus is crucial for adjusting the required transcriptional responses. We show that ANAC017, the master regulator of mitochondrial stress, directly recruits a signaling cascade involving the plant hormones ethylene and auxin as well as the MAP KINASE KINASE (MKK) 9-MAP KINASE (MPK) 3/6 pathway in Arabidopsis thaliana. Chromatin immunoprecipitation followed by sequencing and overexpression demonstrated that ANAC017 directly regulates several genes of the ethylene and auxin pathways, including MKK9, 1-AMINO-CYCLOPROPANE-1-CARBOXYLATE SYNTHASE 2, and YUCCA 5, in addition to genes encoding transcription factors regulating plant growth and stress responses such as BASIC REGION/LEUCINE ZIPPER MOTIF (bZIP) 60, bZIP53, ANAC081/ATAF2, and RADICAL-INDUCED CELL DEATH1. A time-resolved RNA-seq experiment established that ethylene signaling precedes the stimulation of auxin signaling in the mitochondrial stress response, with a large part of the transcriptional regulation dependent on ETHYLENE-INSENSITIVE 3. These results were confirmed by mutant analyses. Our findings identify the molecular components controlled by ANAC017, which integrates the primary stress responses to mitochondrial dysfunction with whole plant growth via the activation of regulatory and partly antagonistic feedback loops.

description: The economics literature increasingly recognizes the importance of migration and its ties with many other aspects of development and policy. Examples include the role of international remittances (Harrison et al, 2003) or those immigrant-links underpinning the migration-trade nexus (Gould, 1994). More recently Walmsley and Winters (2005) utilised a Global Migration model (GMig) to demonstrate that lifting restrictions on the movement of natural persons would significantly increase global welfare with the majority of benefits accruing to developing countries. Although an important result, the lack of bilateral labor migration data forced Walmsley and Winters (2005) to make approximations in important areas and naturally precluded their tracking bilateral migration agreements. In a new technical paper, Walmsley, Winters, and Ahmed incorporate bilateral labor flows into the GMig model developed by Walmsley and Winters (2005) to examine the impact of liberalizing the temporary movement of natural persons. Quotas on both skilled and unskilled temporary labor in the developed economies are increased by 3% of their labor forces. This additional labor is supplied by the developing economies. The results confirm that restrictions on the movement of natural persons impose significant costs on nearly all countries, and that those on unskilled labor are more burdensome than those on skilled labor. Developed economies increasing their skilled and unskilled labor forces by 3% raise the real incomes of their permanent residents. Most of those gains arise from the lifting of quotas on unskilled labor. On average the permanent residents of developing countries also gain in terms of real incomes from sending unskilled and skilled labor, albeit the gains are lower for skilled labor. While results differ across developing economies, most gain as a result of the higher remittances sent home.
Search for disappearing tracks in proton-proton collisions at $\sqrt{s} =$ 13 TeV

description: A search is presented for long-lived charged particles that decay within the volume of the silicon tracker of the CMS experiment. Such particles can produce events with an isolated track that is missing hits in the outermost layers of the silicon tracker, and is also associated with little energy deposited in the calorimeters and no hits in the muon detectors. The search for events with this "disappearing track" signature is performed in a sample of proton-proton collisions recorded by the CMS experiment at the LHC with a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 101 fb$^{-1}$ recorded in 2017 and 2018. The observation of 48 events is consistent with the estimated background of 47.8 $_{-2.3}^{+2.7}$ (stat) $\pm$ 8.1 (syst) events. Upper limits are set on chargino production in the context of an anomaly-mediated supersymmetry breaking model for purely wino and higgsino neutralino scenarios. At 95% confidence level, the first constraint is placed on chargino masses in the higgsino case, excluding below 750 (175) GeV for a lifetime of 3 (0.05) ns. In the wino case, the results of this search are combined with a previous CMS search to produce a result representing the complete LHC data set recorded in 2015-2018, the most stringent constraints to date. At 95% confidence level, chargino masses in the wino case are excluded below 884 (474) GeV for a lifetime of 3 (0.2) ns.

description: A study on diseases of African stargrass was carried out in a pasture in the county of Rio Branco, state of Acre in 2006. A plot of 30 x 30m was randomly selected on a pasture mainly covered by the grass and sample of plants with symptoms of blight leaves present in patches were collected and brought to the Phytopathology Laboratory for analysis. In the field, each patch was drawn in a sketch which was scanned and used for analysis of spatial distribution of the disease in the area using a software for analysis of images. From the samples with symptoms of diseases five isolates of a fungi Mycelia Sterilia were obtained and after analysis it was identified as Rhizoctonia solani. Plants of the same cultivar were grown in sterilized soil and inoculated by deposition of disks of fungi mycelium over the leaves of the plants and conditioned in a wet and warm environment. Disks of the growing medium without the fungi were deposited over the leaves of the control plants. After 48 hours of inoculation typical disease symptoms were reproduced in the inoculated plants. The symptomathology in plants collected in the field is characterized initially by a gray leaf spot in the sheaths and blades, followed by the sheath and leaf blight. The isolated spot evolve towards a light brown to beige color with margins defined by a dark line in the leaf sheath and blades. The evolution of the disease to continuous leaf spot result in a symptom characterized as leaf blight. In the field, the disease presente a uniform pattern of spatial distribution with 6.62% of the pasture area affected.

description: Polypodium vulgare L. (Polypodiaceae) is a fern used in traditional Polish medicine as an expectorant to treat cough and pertussis. Additionally, it was used as a diuretic in renal diseases, especially in chronic nephritis and pyelonephritis. In our study, a water extract was prepared from the rhizome of common polypody and subsequently fractionated on a resin column. As a result, the mixture of flavan-3-ol derivatives was obtained after the column elution with 60% methanol. Further purification by various chromatographic techniques led us to the isolation of (+)-afzelechin (1), a new previously not reported (+)-afzelechin-7-O-α-l-arabinofuranoside (2), and three other monomer flavan-3-ol glycosides: (+)-afzelechin-7-O-β-d-apiofuranoside (3), (+)-catechin-7-O-α-l-arabinofuranoside (4) and (+)-catechin-7-O-β-d-apiofuranoside (5). Structures of the compounds were established by HR-ESI-MS, 1D and 2D NMR spectroscopy. The HSQC and HMBC NMR techniques were used in the structure elucidation of the position of sugar attachment.
