description: Fast radio bursts (FRBs) are bright extragalactic transients likely produced by magnetars. We study the propagation of FRBs in magnetar winds, assuming that the wind is strongly magnetized and composed of electron-positron pairs. We focus on the regime where the strength parameter of the radio wave, $a_0$, is larger than unity, and the wave frequency, $ω_0$, is larger than the Larmor frequency in the background magnetic field, $ω_{\rm L}$. We show that strong radio waves with $a_0>1$ are able to propagate when $ω_0 > a_0ω_{\rm L}$, as the plasma current is a linear function of the wave electric field. The dispersion relation is independent of the wave strength parameter when $ω_0 > a_0ω_{\rm L}$. Instead, radio waves could be damped when $ω_0 < a_0ω_{\rm L}$, as a significant fraction of the wave energy is used to compress the plasma and amplify the background magnetic field. Our results suggest that FRBs should be produced at large distances from the magnetar (i.e., $R>10^{12}{\rm\; cm}$, where the condition $ω_0 > a_0ω_{\rm L}$ is satisfied). Alternatively, the structure of the magnetar wind should be strongly modified during a flare to allow the escape of FRBs produced at radii $R<10^{12}{\rm\; cm}$.

description: Radio detection of inclined air showers is currently receiving great attention. To exploit the potential, a suitable event reconstruction needs to be developed. The first step in this direction is the development of a model for the lateral distribution of the radio signals, which in the case of inclined air showers exhibits asymmetries due to "early-late" effects in addition to the usual asymmetries from the superposition of charge-excess and geomagnetic emission. We present a model which corrects for all asymmetries and successfully describes the lateral distribution of the energy fluence with a rotationally symmetric function. This gives access to the radiation energy as a measure of the energy of the cosmic-ray primary, and is also sensitive to the depth of the shower maximum.

description: The ionosphere contributes time-varying Faraday Rotation (FR) to radio signals passing through it. Correction for the effect of the ionosphere is important for deriving magnetic field information from FR observations of polarized cosmic radio sources, as well as providing valuable diagnostics of the structure of the ionosphere. In this paper, we evaluate the accuracy of models commonly used to correct for its effects using new observations of pulsars at low frequencies, which provide total rotation measures (RM) at better precision than previously available. We evaluate models of the ionosphere derived from modern digital ionosondes that provide electron density information as a function of height, as well as GPS-derived Total Electron Content (TEC) measurements. We combine these density models with reference global magnetic field models to derive ionospheric RM contributions. We find that the models disagree substantially with each other and seek corrections that may explain the differences in RM prediction. Additionally we compare these models to global TEC models and find that local high-cadence TEC measurements are superior to global models for ionospheric RM correction.

description: Based on the world DIS data we extract the experimental F_2^p-F_2^n as a function of Bjorken-x and photon virtuality Q^2, using two different methods. Both methods lead to identical results. We find that the standard PDFs fail to describe the experimental data below Q^2 < 7 GeV^2, which is much higher than for F_2^p and F_2^d separately. The difference between PDFs and the experimental data cannot be understood as due to nuclear effects in the deuteron, and evidently suggests substantial nonsinglet higher-twist effects. The trend of the experimental data is approximately explained by a recent two-component model of the nucleon structure functions and suggests strong Q^2-dependence of the Gottfried Sum, in disagreement with the parton model interpretation. The large negative higher-twist effects can explain the difference between the value of the Gottfied integral obtained recently by the E866 Drell-Yan experiment at Fermilab and an older NMC result.

description: Abridged: We present the first observation of the HCO+(1-0) and HCN(1-0) emission in the northern filaments of Centaurus A with ALMA. HCO+(1-0) is detected in 9 clumps of the Horseshoe complex, with similar velocities as the CO(1-0) emission. Conversely, the HCN(1-0) is not detected and we derive upper limits on the flux. At a resolution of ~40 pc, the line ratio of the velocity-integrated intensities I_HCO+/I_CO varies between 0.03 and 0.08, while I_HCO+/I_HCN is higher than unity with an average lower limit of 1.51. These ratios are significantly higher than what is observed in nearby star-forming galaxies. Moreover, the ratio I_HCO+/I_CO decreases with increasing CO integrated intensity, contrary to what is observed in the star-forming galaxies. This indicates that the HCO+ emission is enhanced and may not arise from dense gas within the Horseshoe complex. This hypothesis is strengthened by the average line ratio I_HCN/I_CO<0.03 which suggests that the gas density is rather low. Using non-LTE, large velocity gradient modelling with RADEX, we explored two possible phases of the gas, that we call "diffuse" and "dense", and are characterised by a significant difference in the HCO+ relative abundance to CO, respectively N_HCO+/N_CO=10^-3 and 3x10^-5. The average CO(1-0) and HCO+(1-0) integrated intensities and the upper limit on HCN(1-0) are compatible with both "diffuse" and "dense" gas. The spectral setup of the present observations also covers the SiO(2-1). While undetected, the upper limit on SiO(2-1) is not compatible with the RADEX predictions for the "dense" gas. We conclude that the 9 molecular clouds detected in HCO+(1-0) are likely dominated by diffuse molecular gas. While the exact origin of the HCO+(1-0) emission remains to be investigated, it is likely related to the energy injection within the molecular gas that prevents gravitational collapse and star formation.

description: Two triterpene saponins (IPS-1, IPS-2) for the first time were isolated from the roots of Impatiens parviflora DC. (Balsaminaceae). Their anti-inflammatory activity was evaluated by means of two in vitro models: anti-hyaluronidase and anti-denaturation assays. Both saponins were shown to be potent hyaluronidase inhibitors that affect the enzyme in a dose-dependent manner. The anti-hyaluronidase effect of IPS-2 (IC50 = 286.7 µg/mL) was higher than that of the reference drug: escin (IC50 = 303.93 µg/mL). Both saponins protected bovine serum albumin from heat-induced denaturation in a dose-dependent manner. IPS-1 demonstrated higher anti-denaturation effect (IC50 = 86.7 µg/ml) than IPS-2 (IC50 = 109.76 µg/mL) or the standard drug: acetylsalicylic acid (IC50 = 262.22 µg/mL). In conclusion, potent activity of IPS-1, IPS-2 in both in vitro assays shows that saponins from I. parviflora have anti-inflammatory activity. The obtained results allow to suggest that such compounds may be beneficial in inflammatory conditions, especially associated with excessive degradation of hyaluronic acid.

description: Grafting onto resistant/tolerant rootstocks is known to alleviate the negative effects of abiotic stress factors like salinity by enhancing their enzymatic antioxidant defense system and having more efficient nutrient uptake. This study was carried out under greenhouse conditions, different rootstock/scion eggplant combinations were grown under two salinity treatments 1.8-2 dS/m (control) and 6-7 dS/m (stress) with seven eggplant genotypes as rootstocks (commercial and Turkish genotypes). Two genotypes were used as the scion. Leaf MDA and ions (Na+, Cl-, K+ and Ca++) content, antioxidant enzymes activity were evaluated as indicators for plant tolerance level. It was found that the rootstock-grafted plants were more efficient in preventing Na+ ions to be transferred to the plants upper parts and had higher SOD, CAT, and APX activity levels compared to the self- and non-grafted plants which resulted in better tolerance and growth in these plants.

description: In this study, the effect of foliar application of Asparagine (ASN) and Casein (CSN) during the vegetative stage at four rates (0, 50, 100 and 150 mg l-1) was investigated on garden cress (Lepidium sativum L.). The results showed that asparagine application, especially at a high level, could significantly increase the morpho-physiological traits such as plant height, leaf and stem fresh weights and leaf and stem dry weights, leaf pigments (chlorophyll a and chlorophyll b) and leaf nutrients content (Nitrogen and Phosphorus). Also, the results indicated that casein application at 50 mg l-1 rate had the best performance through in stem and root fresh weights, stem dry weight and diameter of main stem traits. Casein application at rate 100 mg l-1 had the highest leaf nitrogen and phosphorus content. Generally, our findings suggest that the use of asparagine and casein can be considered as an appropriate growth regulator in garden cress cultivation.

These variables are appropriate for describing the theory in its infrared limit, and indicate that it admits knotlike configurations as stable solitons. As a consequence we arrive at a dual picture of the Yang-Mills theory where the short distance limit describes asymptotically free, massless point gluons and the large distance limit describes extended, massive knotlike solitons.

description: Gyroscopic metamaterials --- mechanical structures composed of interacting spinning tops --- have recently been found to support one-way topological edge excitations. In these structures, the time reversal symmetry breaking that enables their topological behavior emerges directly from the lattice geometry. Here we show that variations in the lattice geometry can therefore give rise to more complex band topology than has been previously described. A `spindle' lattice (or truncated hexagonal tiling) of gyroscopes possesses both clockwise and counterclockwise edge modes distributed across several band gaps. Tuning the interaction strength or twisting the lattice structure along a Guest mode opens and closes these gaps and yields bands with Chern numbers of $|C| > 1$ without introducing next-nearest-neighbor interactions or staggered potentials. A deformable honeycomb structure provides a simple model for understanding the role of lattice geometry in constraining the effects of time reversal symmetry and inversion symmetry breaking. Lastly, we find that topological band structure generically arises in gyroscopic networks, and a simple protocol generates lattices with topological excitations.

description: The effects of pulse and permanent treatments were studied on vase life, water content and hydraulic conductivity of gerbera cut flower cv. Rosalin. This study was conducted as a factorial experiment based on completely randomized design with three replications. The first factor was pulse treatments, using nanosilver (NS) 5 and 10 mg/L, salicylic acid (SA) 50 and 100 mg/L and distilled water as control, and the second factor was permanent treatments applying distilled water, sucrose, peppermint, thyme and clove essential oils (EO). The results showed that NS 10 mg/L + peppermint EO 100 mg/L and NS 10 mg/L + thyme EO 100 mg/L treatments had the best effect on longevity and maintaining the water content and hydraulic conductance of Rosalin cut flower, compare to other treatments. These solutions enhanced life of gerbera cut flowers to about 14 days. Flower water content was high (about 90%) except in 4% sucrose permanent treatment flowers which decreased more rapidly during the vase life. The effective hydraulic conductivity was observed in NS 10 mg/L + peppermint EO 100 mg/L (0.16 cm/min) and NS 10 mg/L + thyme EO 100 mg/L (0.21 cm/min) solutions and had nearly stable trend even in day 8 after pulsing.

description: Jupiter's icy moon Ganymede has a tenuous exosphere produced by sputtering and possibly sublimation of water ice. To date, only atomic hydrogen and oxygen have been directly detected in this exosphere. Here, we present observations of Ganymede's CO$_2$ exosphere obtained with the James Webb Space Telescope. CO$_2$ gas is observed over different terrain types, mainly over those exposed to intense Jovian plasma irradiation, as well as over some bright or dark terrains. Despite warm surface temperatures, the CO$_2$ abundance over equatorial subsolar regions is low. CO$_2$ vapor has the highest abundance over the north polar cap of the leading hemisphere, reaching a surface pressure of 1 pbar. From modeling we show that the local enhancement observed near 12 h local time in this region can be explained by the presence of cold traps enabling CO$_2$ adsorption. However, whether the release mechanism in this high-latitude region is sputtering or sublimation remains unclear. The north polar cap of the leading hemisphere also has unique surface-ice properties, probably linked to the presence of the large atmospheric CO2 excess over this region. These CO2 molecules might have been initially released in the atmosphere after the radiolysis of CO$_2$ precursors, or from the sputtering of CO$_2$ embedded in the H$_2$O ice bedrock. Dark terrains (regiones), more widespread on the north versus south polar regions, possibly harbor CO$_2$ precursors. CO$_2$ molecules would then be redistributed via cold trapping on ice-rich terrains of the polar cap and be diurnally released and redeposited on these terrains. Ganymede's CO$_2$ exosphere highlights the complexity of surface-atmosphere interactions on Jupiter's icy Galilean moons.

The missing normal derivatives are compensated through the equations of the linearized vorticity and entropy when deriving higher-order energy estimates. The proof of the resolution for this nonlinear problem follows from certain \emph{a priori} tame estimates on the effective linear problem {in the usual Sobolev spaces} and a suitable Nash--Moser iteration scheme.

description: Interferometer observations of millimeter-continuum (OVRO) and single-dish observations of HCO+ and H13CO+ J=1-0, 3-2, and 4-3 (JCMT, IRAM 30m) are presented of nine embedded low-mass young stellar objects (YSOs) in Taurus. All nine objects are detected at 3.4 and 2.7 mm, with fluxes of 4-200 mJy, and consist of unresolved (<3 arcsec) point sources, plus, toward about half of the objects, an extended envelope. The point sources likely are circumstellar disks, showing that these are established early in the embedded phase. Literature values of 1.1 mm continuum emission are used to trace the envelopes, carrying 0.001-0.26 M(sol). In HCO+, the 1-0 lines trace the surrounding clouds, while the 3-2 and 4-3 are concentrated toward the sources with intensities well correlated with the envelope flux. An HCO+/H2 abundance of 1.2e-8 is derived. The HCO+ line strengths and envelope fluxes can be fit simultaneously with the simple collapse model of Shu (1977), and related density power laws with slopes p=1-3. As an indicator of the relative evolutionary phase of a YSO, the ratio of HCO+ 3-2 line intensity over bolometric luminosity is proposed, which is roughly proportional to the current ratio of envelope over stellar mass. It is concluded that HCO+ 3-2 and 4-3 are excellent tracers of the early embedded phase of star formation.

description: Medicinal plants are one of the main natural resources of Iran from ancient times. Perilla is one of the most important medicinal plants of the mint family Lamiaceae, since there is no study about adaptability of Perilla in Iran climate conditions and different fertilizer systems, this experiment was conducted in two experimental sites. The experiment was conducted as split-plot factorial based on a randomized complete block design with three replications at two experimental regions. The main factor was three chemical fertilizer levels (control, 50, 100, 200 kg/ha) and subplots were different kinds of organic fertilizer (control, humic acid, and compost application) and inoculation with Piriform osporaindica (inoculation and without). Among levels of chemical treatments, 50 and 100 kg/ha lead to a better result. Also, humic acid allows to achieve the highest amount of measured traits between different treatments of organic fertilizer. The highest plant yield (147.2 g/m2) and rosmarinic acid yield per area (3.432 g/m2) was achieved in 100 kg/ha at chemical fertilizer with humic acid and biological fertilizer application and the lowest plant yield (89.86 g/m2) and rosmarinic acid yield per area (1.253 g/m2) was observed in control. Also, the highest stomatal conductance was obtained with application of compost fertilizer (67.67 mmol H2O m-2s-1). Integrated application of the studied fertilizers showed the more positive effect on yield and quality of Perilla than individual application of those fertilizers.

description: The consequences of large radius extra space-time compactified dimensions on the four dimensional one loop effective potential are investigated for a model which includes scalar self interactions and Yukawa coupling to fermions. The Kaluza-Klein tower of states associated with the extra compact dimensions shifts the location of the effective potential minimum and modifies its curvature. The dependence of these effects on the radius of the extra dimension is illustrated for various choices of coupling constants and masses. For large radii, the consequence of twisting the fermion boundary condition on the compactified dimensions is numerically found to produce but a negligible effect on the effective potential.

description: The Transition-Edge Sensors (TES) is a mature, high-resolution x-ray spectrometer technology that provides a much higher efficiency than dispersive spectrometers such as gratings and crystal spectrometers. As larger arrays are developed, time-division multiplexing schemes operating at MHz frequencies are being replaced by microwave SQUID multiplexers using frequency-division multiplexing at GHz frequencies. However, the multiplexing factor achievable with microwave SQUIDs is limited by the high slew rate on the leading edge of x-ray pulses. In this paper, we propose a new multiplexing scheme for high-slew-rate TES x-ray calorimeters: the spread-spectrum SQUID multiplexer, which has the potential to enable higher multiplexing factors, especially in applications with lower photon arrival rates.

description: Lilium is one of the most important ornamental plants after roses, carnations and chrysanthemum in the world that is requested as potted of cut flowers. It is so important to consider its quality along with its production rate in terms of yield (quantity). However, it always needs to intend the product costs aside from quantity and quality. Fertilizer utilization is so important and this may be improved by compounds that promote it and also have synergetic effects themselves. We examined both carboxymethylated chitosan (CMC) and magnetic nano-carbocymethylated chitosan (MNCC) to produce Lilium bulb and advised them especially magnetic chitosan. In this study, these compounds (magnetic and non-magnetic chitosan) at concentrations of zero, 2.5, 5, 10 and 15 mg/l were examined during lily forcing in three cultivars, including Cherbourg, Navona, Brunello, which are from Asiatic and Oriental lilies. The results showed that highest concentrations (10 and 15 mg/l) among between examined concentrations regardless of compounds types and cultivars did not make toxicity and had significant effects on plants biology and physiology [contents of carbohydrates and enzymes affecting these carbohydrates (amylases)]. However, for observing morphological changes may be need to use higher concentrations of these compounds. Note that this needs to examine the non-toxicity of higher concentrations in future studies.

description: Using sclareol and sclareolide as starting materials, the guanidine derivatives of 12-amino-11-dihomodrimane-8α-ol and 13-amino-14,15-bis-dinorlabd-8(9)-ene were synthesized by the reaction of the corresponding amines with sodium hydrogencyanamide in ethanol – water solution. Monoacyl- and diacylguanidines were prepared from activated with N,N-carbonyldiimidazole Δ8,9-bicyclohomofarnesenoic acid by the reaction with guanidine. Their structures were confirmed by the 1H and 13C NMR, IR spectral and elemental analysis data. The compounds 12, 13 and 15 were screened for their antiproliferative and cytotoxicity activities against Colo 205, Colo 320 and MRC 5 human lung fibroblasts with respect to standard drug, Cisplatin. The compounds 12 and 15 exhibits excellent results than positive control. Hence these two compounds may be act as drug lead molecules in cancer chemotherapy.

description: Tobacco dust (TD) waste is the typical lignocellosic agricultural residue of cigarette processing. In the region of Peloponnese, cigarette production is carried out by the leading company of Karelias S.A. The production of TD waste of approx. 2-3 tons/month is a major problem for the company. Plant growth media containing peat (P) + 0, 5, 10, 25 or 50% TD were prepared and tested on geranium plant growth and development. The use of TD increased EC and pH of the final medium. Plants of the cvs “ML Diego” and “ML Sailing ‘12” grown in P+5% or in P+10% TD had similar height, number of leaves, number of flowers, photosynthetic activity and transpiration rates to the P alone (control) indicating that solid agro-industrial waste of tobacco could be used to partially substitute peat in growing medium for floricultural crop production.

description: One of the important products in Iran and Isfahan province is the pear that its cultivation has been limited by drought stress and global warming in recent years. The use of drought-tolerant rootstocks is one of the available solutions for pear orchards in semi-arid regions. In addition, the lack of dwarf or semi-dwarf rootstocks, which are appropriate and compatible with Iran climatic conditions, limited high density pear orchards. In order to obtain drought tolerant rootstocks, in this research fruit of Pyrus glabra, Pyrus syriaca, and Pyrus salicifolia, along with P. communis cv. Spadona, Dargazi, as well as Khoj n. 1 and n. 2 species were collected from different regions of Iran in August and September of 2016. The seeds were separated from the flesh and dried at room temperature. The seeds were cultivated in uniform and light texture of soil in November in the field condition to break the seed dormancy. Seedlings were irrigated regularly for three months in order to establish in the soil; drought stress began in July. In order to apply drought stress, irrigation time was considered based on 80% of allowed water depletion. Morphological traits of seedlings were recorded before stress and at the end of the stress period (late September). The viability percentage of seedlings after drought stress was between 14.28% (P. communis cv. Dargazi progenies) to 82.55% for P. salicifolia. Comparison of the means and cluster analysis, among populations showed that the three populations of P. salicifola, P. glabra and P. communis cv. Khoj n. 2 had the lowest height and were placed in the same group. After studying single genotypes in these three populations, genotypes no. 31, 32, 41, 57 and 12 from P. salicifolia, genotypes 10, 11, 7, 3 and 9 of P. glabra and genotype 4 of P. communis cv. Khoj n. 2 populations were selected as drought tolerant and dwarf genotypes and were taken to the propagation phase for future evaluation.

description: New, deep HST photometry allowed us to identify and study eight compact and bright (M_V< -5.8) star clusters in the outskirts of the star-forming isolated dwarf galaxy NGC5238 (M_*= 10^8 M_sun). Five of these clusters are new discoveries, and six appear projected onto, and/or aligned with the tidal tails recently discovered around this galaxy. The clusters are partially resolved into stars and their colour magnitude diagrams reveal a well developed red giant branch, implying ages older than 1-2~Gyr. Their integrated luminosity and structural parameters are typical of classical globular clusters and one of them has M_V=-10.56 +/- 0.07, as bright as Omega Cen, the brightest globular cluster of the Milky Way. Since the properties of this cluster are in the range spanned by those of nuclear star clusters we suggest that it may be the nuclear remnant of the disrupted satellite of NGC5238 that produced the observed tidal tails.

description: In this article we prove three obstruction results on the existence of equations of state in clusters of stellar systems fulfilling mass-radius relationships and some additional bound (on the mass, on the radius or a causal bound). The theorems are proved in large generality. We start with a motivating example of TOV systems and we close by applying our results in stellar systems arising from experimental data.

description: Paeonia daurica subsp. tomentosa (Lomakin) D.Y.Hong is an herbaceous perennial and flowering plant from the Paeoniaceae family. In this research, the roots, stems, leaves and fruits of P. daurica subsp. tomentosa were investigated for a comparative identification of essential oil composition. The essential oils constituents were identified by GC/MS and then compared. The study leads to the identification of 31, 57, 66, and 57 components in the essential oils obtained from the roots, stems, leaves and fruits, respectively. These chemicals make up more than 99% of the essential oil. Some of the identified compounds (α-Pinene, 4-ethyloctane, 5-methylnonane, benzaldehyde, myrtanal, 4,7-dimethyl benzofuran, n-decane, cuminaldehyde, cis-p-mentha-6,8-diene-2-ol, salicylaldehyde, tetradecane, tetradecanal, and n-tricosane) occurred in all parts of the plant. The existence of compounds such as cembrene (1.1%), 13-epi-manool (1.5%), 2-hydroxy methyl benzoate (10.1%), and tridecanal (0.7%), however, were confirmed exclusively in the fruit, stem, root, and leaf, respectively. The antibacterial activities (MIC) of the oils obtained from the four studied Paeonia parts against Escherichia coli and Staphylococcus aureus was studied. Staphylococcus aureus was the most sensitive microorganism to the oil obtained from the fruits of P. daurica subsp. tomentosa with the value of 0.04 ± 0.005 mg mL−1.

description: Our goal in this paper is to examine the discovery potential of laboratory experiments searching for the oscillation $ν_μ(ν_e) \rightarrow ν_τ$, in the light of recent data on solar and atmospheric neutrino experiments, which we analyse together with the most restrictive results from laboratory experiments on neutrino oscillations. In order to explain simultaneously $all$ present results we use a four-neutrino framework, with an additional sterile neutrino. Our predictions are rather pessimistic for the upcoming experiments NOMAD and CHORUS, which, we find, are able to explore only a small area of the oscillation parameter space. On the other hand, the discovery potential of future experiments is much larger. We consider three examples. E803, which is approved to operate in the future Fermilab main injector beam line, MINOS, a proposed long-baseline experiment also using the Fermilab beam, and NAUSICAA, an improved detector which improves by an order of magnitude the performance of CHORUS/NOMAD and can be operated either at CERN or at Fermilab beams. We find that those experiments can cover a very substantial fraction of the oscillation parameter space, having thus a very good chance of discovering $both$ $ν_μ\rightarrow ν_τ$ and $ν_e \rightarrow ν_τ$ oscillation modes.

description: Motivated by the immense popularity and social influence of Twitter in the Gulf region, this study aims to investigate the impact of the verification status of users on their language style, and to determine the extent to which verified and unverified accounts vary in relation to gender, language, and content. This research is exploratory and relies on a corpus-study approach. The four corpora compiled for the experiment include 588,000 tweets extracted from 84 verified and 84 unverified accounts of the male and female users living in the Gulf Cooperation Council (GCC) countries. The obtained data have been examined with the help of the AntConc tool, which generated the lists of trademark words and high-frequency words. The results analysis suggests that verified and unverified users have different language styles in terms of formal and informal expressions, choice of topics and language expressivity. Furthermore, although the study confirms expected gender differences in language style, our examination refines and adds to the previous research by demonstrating that these differences are less pronounced in verified accounts. Both male and female users with verified status adopt a stance of objectivity and professionalism, making gender variable less noticeable. The thesis therefore argues that gender is not the only factor influencing one’s linguistic choices: language variations in style and dialect diminish once a person becomes a brand and a voice of a larger community.
