description: Recent space-based observations (e.g., Kepler mission) found thousands of ``superflares’’ on G-, K-, and M-type stars. These superflare stars show quasi-periodic brightness variations caused by the rotation of the star with starspots. We analyzed the statistical properties of starspots on G-, K-, and M-type stars and their correlation with the flare activity. The analysis shows that the fraction of stars showing large-amplitude rotational variations, which are thought to be the signature of the large starspots, decreases as the rotation period increases. We found that there is a good correlation between the bolometric energy of the largest superflares and area of starspots estimated from the amplitude of rotational light variations. The bolometric energy released by the largest flare on the star is consistent with the magnetic energy stored near the starspots. We also found that the frequency of superflares correlates with the starspot area. The average frequency of flares with a given bolometric energy is roughly proportional to the area of starspots. Our results suggest that flare activity level (e.g., energy of the largest flares, occurrence frequency) of the late-type stars can be determined by the area of starspots.

Subjects: Nonlinear Schrödinger equation; planar defects; solitons; localized states; nonlinear waves

description: We consider the nonlinear excitation localized near the media interface with an internal structure. We consider the anharmonicity of the medium characterized by a different nonlinearity on different sides of the interface. The excitations are described by nonlinear Schrödinger equation with modified short-range interaction potential. The problem is reduced to the solution of the nonlinear Schrödinger equation with the boundary conditions of a special kind. We found the exact solutions of nonlinear Schrödinger equations satisfying the boundary conditions. We show that the existence of nonlinear localized excitations of several types is possible. They have a soliton-like profile in the direction perpendicular to the boundary. The structure and shape of the localized states is determined by the anharmonicity parameters and the intensity of interaction of the excitations with the planar defect. We found the energy of nonlinear excitation in explicit form in special cases.

description: Hyperspectral imaging (HSI) has recently emerged as a promising tool for many agricultural applications; however, the technology cannot be directly used in a real-time system due to the extensive time needed to process large volumes of data. Consequently, the development of a simple, compact, and cost-effective imaging system is not possible with the current HSI systems. Therefore, the overall goal of this study was to reconstruct hyperspectral images from RGB images through deep learning for agricultural applications. Specifically, this study used Hyperspectral Convolutional Neural Network - Dense (HSCNN-D) to reconstruct hyperspectral images from RGB images for predicting soluble solid content (SSC) in sweet potatoes. The algorithm accurately reconstructed the hyperspectral images from RGB images, with the resulting spectra closely matching the ground-truth. The partial least squares regression (PLSR) model based on reconstructed spectra outperformed the model using the full spectral range, demonstrating its potential for SSC prediction in sweet potatoes. These findings highlight the potential of deep learning-based hyperspectral image reconstruction as a low-cost, efficient tool for various agricultural uses.

description: The notion of the flow introduced by Kitaev is a manifestly topological formulation of the winding number on a real lattice. First, we show in this paper that the flow is quite useful for practical numerical computations for systems without translational invariance. Second, we extend it to three dimensions. Namely, we derive a formula of the flow on a three-dimensional lattice, which corresponds to the conventional winding number when systems have translational invariance.

description: In the present study, polyaniline (PAni) was coated on the surface of sisal fibers (SF) through in situ oxidative polymerization method which was further characterized using FT-IR, UV-Vis, XRD, SEM and EDX instruments. PAni/SF composite was tested to remove potentially harmful hexavalent chromium(CrVI) from simulated waste water on batch adsorption experiment as a function of adsorption variables such as contact time, solution pH, particle size, adsorbent dose and adsorbate dose. It was observed that adsorption of Cr(VI) is highly susceptible to pH change with maximum adsorption removal (93.1%) and adsorption capacity (12.7 mg/g) achieved at pH 4. Studies on adsorption reaction revealed adsorption process followed pseudo second order kinetics confirming chemisorption as rate determining step. The isotherm data was suitably fitted to Langmuir model with maximum adsorption capacity (qm) 17.86 mg/g when all adsorption variables were optimized.

description: An investigation into the structural, electronic, magnetic and optical properties of oxyphosphate Fe0.5TiOPO4 was conducted using first-principles calculations based on density functional theory (DFT) with the Plane-Wave Self-Consistent Field (PWSCF). The results are used to discuss the quality of the generalized-gradient expansion GGA and GGA+U approximation for describing these atoms. We showed that the obtained symmetry lattice parameter agree well with the experimental results. The influence of iron element on the magnetic and electronic properties of oxyphosphate Fe0.5TiOPO4 is analyzed. The electronic structure calculations for monoclinic oxyphosphate Fe0.5TiOPO4 predict an energy-gap in both spin-up and spin-down. The partial density of states (PDOS) of Fe0.5TiOPO4 show that the oxygen 2p-derived states hybridize strongly with iron-3d at the conduction band when it’s hybridize with titanium and iron at the valance band and the theoretical band gap energy is found to be Eg=0.62eV (GGA) and 2.2 eV (GGA+U).

description: Here, we present the 1UVA catalog of time variable ultraviolet (UV) sources. We describe a new analysis pipeline, the VAriable Source Clustering Analysis (VASCA). We apply the pipeline to 10 years of data from the GALaxy Evolution eXplorer (GALEX) satellite. We analyse a sky area of 302 deg$^2$ , resulting in the detection of 4202 time-variable UV sources. We cross correlate these sources with multi-frequency data from the Gaia satellite and the SIMBAD database, finding an association for 3655 sources. The source sample is dominated by Active Galactic Nuclei ($\approx$73 %) and stars ($\approx$24 %). We look at UV and multi-frequency properties of these sources, focusing on the stellar population. We find UV variability for four White Dwarfs. One of them, WD J004917.14-252556.81, has recently been found to be the most massive pulsating White Dwarf. Its Spectral Energy Distribution shows no sign of a stellar companion. The observed flux variability is unexpected and difficult to explain.

description: NaPb2CaSr(PO4)3 lacunar apatite was synthesized by the solid-state reaction method. The compound was characterized by X-ray diffraction, Raman and infrared spectroscopies. The crystal structure of this new compound has been determined by Rietveld method, adopting the space group P63/m (No. 176), with a=b=9.6684(3)Å and c=7.1104(3)Å The analysis shows that the M(2) sites are shared by four cations Ca, Sr, Pb and Na. While the M(1) sites are occupied by the Ca, Sr and Pb cations. The structure was described as built up from [PO4]3- tetrahedra and Pb2+/Ca2+/Sr2+ of sixfold coordination cavities (6h positions), which delimit void hexagonal tunnels running along [0 0 1]. The tunnels are connected by cations of mixed sites (4f) half occupied by Pb2+/ Ca2+/Sr2+ and half by Na+ mixed alkali cation. The results of vibrational spectroscopy are in good agreements with the XRD measurements, the assignments of internal modes of (PO4)3- tetrahedra have been made and corroborate well with factor group analysis for the symmetry P63/m. An attempt to purify phosphoric acid is done using our apatite and the results are promising.

description: Using Fe-containing silica-alumina materials as heterogeneous catalyst for Fenton-like degradation of organic pollutants has attracted a lot of attention during the last decades. In this work the catalytic activity of an iron-rich natural silica-alumina material (namely volcanic ash) for the abatement of Rhodamine 6G (Rh6G) has been evaluated. The X-ray diffraction (XRD) and Scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS) results showed that such material contains about 13 wt% of iron mainly present in augite and ferroan forsterite crystalline phases. Such iron content was sufficient to activate hydrogen peroxide via Fenton process. Indeed, 78% of Rh6G was degraded after 120 min of reaction in the presence of volcanic ash ([VA] = 5 g/L; [Rh6G] = 25 mg/L and initial pH = 3). The dye abatement efficiency increased with decrease of initial dye concentration, and with increase of catalyst dosage. However, the process was efficient only in acid medium (pH = 2.5 – 3) in which the leaching of the catalyst could not be avoided. As a consequence, a drastic decrease in abatement efficiency was observed during the recyclability test. This suggests that the studied volcanic ash can be used as low cost material for wastewater treatment. However it needs to be pre-treated for efficient use as heterogeneous catalyst.

description: We present optical follow-up of IGR J16194-2810, a hard X-ray source discovered by the INTEGRAL mission. The optical counterpart is a $\sim500\,L_\odot$ red giant at a distance of $2.1$ kpc. We measured 17 radial velocities (RVs) of the giant over a period of $271$ days. Fitting these RVs with a Keplerian model, we find an orbital period of $P_{\rm orb} = 192.73 \pm 0.01$ days and a companion mass function $f(M_2) = 0.365 \pm 0.003 \,M_{\odot}$. We detect ellipsoidal variability with the same period in optical light curves from the ASAS-SN survey. Joint fitting of the RVs, light curves, and the broadband SED allows us to robustly constrain the masses of both components. We find a giant mass of $M_\star = 0.99^{+0.02}_{-0.03}\,M_{\odot}$ and a companion mass of $M_{2} = 1.23^{+0.05}_{-0.03}\,M_{\odot}$, implying that the companion is a neutron star (NS). We recover a $4.06$-hour period in the system's TESS light curve, which we tentatively associate with the NS spin period. The giant does not yet fill its Roche lobe, suggesting that current mass transfer is primarily via winds. MESA evolutionary models predict that the giant will overflow its Roche lobe in $5$-$10$ Myr, eventually forming a recycled pulsar + white dwarf binary with a $\sim 900$ day period. IGR J16194-2810 provides a window on the future evolution of wide NS + main sequence binaries recently discovered via Gaia astrometry. As with those systems, the binary's formation history is uncertain. Before the formation of the NS, it likely survived a common envelope episode with a donor-to-accretor mass ratio $\gtrsim 10$ and emerged in a wide orbit. The NS likely formed with a weak kick ($v_{\rm kick}\lesssim 50\,\rm km\,s^{-1}$), as stronger kicks would have disrupted the orbit.

description: BaCO3, SrCO3, NiO, MoO3 precursors were used as starting materials in the synthesis of double perovskite Ba1/5Sr4/5NiMoO6, and their crystal structure at room tempertaure was solved using X-ray powder diffraction. The Rietveld analysis of X–ray powder diffraction patterns show that both compounds adopt a tetragonal structure with space group I4/m, with unit cell parameters a= 5.58537(1) Å, c=7.9066(2) Å. The structure can be represented as a three-dimensional network of alternating NiO6 and MoO6 octahedra, with Ba and Sr atoms occupying the interstitial spaces. Temperature-induced phase transitions of Ba1/5Sr4/5NiMoO6 were investigated by mean of Raman spectroscopy technique at high temperature up to 392 °C. remarkable in the behaviuor of temperature dependence of the modes has been interpreted as a phase transition from the tetragonal (I4/m) to the cubic () structure.

description: Single-dish far-infrared (far-IR) and sub-millimetre (sub-mm) point source catalogues and their connections with catalogues at other wavelengths are of paramount importance. However, due to the large mismatch in spatial resolution, cross-matching galaxies at different wavelengths is challenging. This work aims to develop the next-generation deblended far-IR and sub-mm catalogues and present the first application in the COSMOS field. Our progressive deblending used the Bayesian probabilistic framework known as XID+. The deblending started from the Spitzer/MIPS 24 micron data, using an initial prior list composed of sources selected from the COSMOS2020 catalogue and radio catalogues from the VLA and the MeerKAT surveys, based on spectral energy distribution modelling which predicts fluxes of the known sources at the deblending wavelength. To speed up flux prediction, we made use of a neural network-based emulator. After deblending the 24 micron data, we proceeded to the Herschel PACS (100 & 160 micron) and SPIRE wavebands (250, 350 & 500 micron). Each time we constructed a tailor-made prior list based on the predicted fluxes of the known sources. Using simulated far-IR and sub-mm sky, we detailed the performance of our deblending pipeline. After validation with simulations, we then deblended the real observations from 24 to 500 micron and compared with blindly extracted catalogues and previous versions of deblended catalogues. As an additional test, we deblended the SCUBA-2 850 micron map and compared our deblended fluxes with ALMA measurements, which demonstrates a higher level of flux accuracy compared to previous results.We publicly release our XID+ deblended point source catalogues. These deblended long-wavelength data are crucial for studies such as deriving the fraction of dust-obscured star formation and better separation of quiescent galaxies from dusty star-forming galaxies.

First astronomical preselecting site in the Beni Mellal region: On the use of satellite data
Creators: name: Siher, A. Salhi
Publisher: name: Journal of Applied Surfaces and Interfaces
Year: 2018
Subjects: Astronomical site testing – satellite data.

description: In this paper we use satellite meteorological and geophysical data to compare three new sites to the Oukaimeden Observatory (J43) located in the Atlas mountains (Morocco). The Three other sites are located in Beni Mellal mountains. The data are obtained from several satellites: MODIS (Moderate Resolution Imaging Spectroradiometer), AIRS (the Atmospheric Infrared Sounding System). Those three sites, located on the middle Atlas Mountain, are not far from the University of Beni Mellal by good roads. As results, we find that these three sites are of good quality and can be qualified to house some astronomical instruments, but in situ data are required.

description: Full sky coverage Adaptive Optics on Extremely Large Telescopes requires the adoption of several Laser Guide Stars as references.With such large apertures, the apparent elongation of the beacons is absolutely significant.With few exceptions,WaveFront Sensors designed for Natural Guide Stars are adapted and used in suboptimal mode in this context. We analyse and describe the geometrical properties of a class of WaveFront Sensors that are specifically designed to deal with Laser Guide Stars propagated from a location in the immediate vicinity of the telescope aperture. We describe in three dimensions the loci where the light of the Laser Guide Stars would focus in the focal volume located behind the focal plane (where astronomical objects are reimaged). We also describe the properties of several types of optomechanical devices that, through refraction and reflections, act as perturbers for this new class of pupil plane sensors, which we call ingot WaveFront Sensor. We give the recipes both for the most reasonable complex version of these WaveFront Sensors, with 6 pupils, and for the simplest one, with only 3 pupils. Both of them are referred to the ELT case. Elements to have a qualitative idea of how the sensitivity of such a new class of sensors compared to conventional ones are outlined. We present a new class of WaveFront Sensors, by carrying out the extension to the case of elongated sources at finite distance of the pyramid WaveFront Sensor and pointing out which advantages of the pyramid are retained and how it can be adopted to optimize the sensing.

description: Determinants are useful to represent the state of an interacting system of (effectively) repulsive and independent elements, like fermions in a quantum system and training samples in a learning problem. A computationally challenging problem is to compute the sum of powers of principal minors of a matrix which is relevant to the study of critical behaviors in quantum fermionic systems and finding a subset of maximally informative training data for a learning algorithm. Specifically, principal minors of positive square matrices can be considered as statistical weights of a random point process on the set of the matrix indices. The probability of each subset of the indices is in general proportional to a positive power of the determinant of the associated sub-matrix. We use Gaussian representation of the determinants for symmetric and positive matrices to estimate the partition function (or free energy) and the entropy of principal minors within the Bethe approximation. The results are expected to be asymptotically exact for diagonally dominant matrices with locally tree-like structures. We consider the Laplacian matrix of random regular graphs of degree $K=2,3,4$ and exactly characterize the structure of the relevant minors in a mean-field model of such matrices. No (finite-temperature) phase transition is observed in this class of diagonally dominant matrices by increasing the positive power of the principal minors, which here plays the role of an inverse temperature.

description: The frequency dependent dielectric and conductivity behavior of a Zn-Al layered double hydroxides (LDH), with Cl– interlayer anion and with Zn/Al ratio R=2, have been studied. The formation of layered double hydroxides (LDH) and changes in the structural properties were investigated by x-ray diffraction (XRD), FTIR and ICP. Electric and dielectric properties were studied over a frequency range of [200Hz–1MHz] and in the temperature from 300K to 375K. These Studies show that the relaxation contribution is superimposed by electrode polarization effect. The appearance of peak for each temperature in the imaginary part of permittivity and modulus suggests the presence of relaxing dipoles in the layered double hydroxides. On increase of temperature, the peak shifts towards higher frequency side suggesting the speed up the relaxation time. The variation of ac conductivity with frequency obeys Jonscher power law except a small deviation in the low frequency region due to electrode polarization effect. The dc conductivity increases with increase in temperature. The temperature dependence of the relaxation times for all samples showed Arrhenius behavior, from which the activation energy was derived.

description: In this study, Zn-Al, Mg-Al and Ni-Al layered double hydroxides were successfully synthesized via co-precipitation method. Samples were characterized by XRD, FTIR, TGA-DTA, TEM and pHPZC analysis. XRD patterns showed a basal spacing increase in the order of Zn-AlNO3 (8.85Å)> Mg-AlNO3 (7.95Å)> Ni-AlNO3 (7.82Å). TEM images indicated that the Zn-AlNO3 presents circular to shaped particles with an average particle size of approximately 30 to 40 nm. Small plates assigned to sheets with hexagonal form were observed in the case of Mg-AlNO3.Ni-AlNO3 display nanostructured sphere in diameter between 5 and 10 nm. The materials were used for the removal of methyl orange (MO), as a model dye and for the treatment of a real effluent generated by a textile factory. Maximum adsorption was occurred in acidic pH solution. Kinetic data were tested using pseudo-first-order, pseudo-second-order kinetic and intra-particle diffusion models. The best fit was obtained with the pseudo-second-order kinetic model. Equilibrium data were correlated to Langmuir, Freundlich, Sips and Redlich–Peterson isotherm models. The best conditions for color and COD removal from the textile effluent sample were obtained at lower values of pH. Reduction of COD to limits authorized by Moroccan standards was obtained with 0.5g/L of LDH dosage.

description: The spatial distribution of molecules in AGB circumstellar envelopes is regulated by different processes. In the outer layers all molecules are destroyed due to the interaction with interstellar ultraviolet photons. Here we aim to characterize in a coherent and uniform way the radial extent of three molecules (SiO, CS, and SiS) in envelopes around AGB stars of O- and C-rich character, and to study their dependence with mass loss rate. To that purpose, we used the Yebes 40m and IRAM 30m telescopes to observe 7 M-type and 7 C-type AGB envelopes covering a wide range of mass loss rates (1e-7 - 1e-5 Msun/yr) in lines of SiO, CS, and SiS spanning a range of upper level energies of 2-130 K. We carried out excitation and radiative transfer calculations over a wide parameter space to characterize the molecular abundance and radial extent. A chi2 analysis indicates that the abundance is well constrained while the radial extent is more difficult to constrain. The radial extent increases with increasing envelope density, in agreement with previous observational findings. At high envelope densities, Mdot/vexp > 1e-6 (Msun/yr)/(km/s), the radial extent of SiO, CS, and SiS are similar, while at low envelope densities, Mdot/vexp < 1e-7 (Msun/yr)/(km/s), the radial extent differ among the three molecules, in agreement with theoretical expectations based on destruction due to photodissociation. At low envelope densities we find a sequence of increasing radial extent, SiS -> CS -> SiO. We also find a tentative dependence of the radial extent with the chemical type (O- or C-rich) of the star for SiO and CS. Interferometric observations and further investigation of the photodissociation of SiO, CS, and SiS should allow to clarify the situation on the relative photodissociation radius of SiO, CS, and SiS in AGB envelopes and the dependence with envelope density and C/O ratio.

This species was originally described based on 2 males (holotype from Venezuela, AMNH; paratype from Guyana, MZSP) and 1 female (from Guyana, AMNH). The paratype belonging to the MZSP collection was reported as being a female but is a male. However, when describing the dimensions of the specimens, Martins and Monné (1993) correctly provided the measurements of two males and one female.
Morvan and Morati (2006) were the first to report this species in French Guiana. Although the paratype female from Guyana was not examined, the holotype and paratype (Fig. 10-13) males are distinctly lighter than specimens from French Guiana (specimens also examined through photographs, Fig. 14–17). In addition to the difference in color, the anterolateral pronotal tubercles are somewhat smaller and more distinctly conical in the holotype and paratype male than in the specimens from French Guiana. However, as no other morphological features were found, it is probable that the differences in the French Guiana specimens are simply local variants.

description: Glasses in the system 33.33[xNa2O-(1-x)Li2O]-2.5SrO-2.5TiO2-45B2O3-16.67P2O5 (0.0 ≤ x ≤ 1.0) were prepared by standard melt quenching procedures, and their physical properties were characterized by thermal analysis, density measurements. Their local structures were comprehensively characterized by Infrared spectroscopy (IR) and electron paramagnetic resonance (EPR). The variation of the glass transition temperature as a function of the glass compositions is non-linear. The infrared spectroscopy of the glasses has identified the presence of different structural grouping units in the glassy-matrix. It is found that the stretching and bending vibration modes of borate groups are more sensitive to the substitution of alkali elements. EPR experiments have shown the presence of Ti3+ centres in the glasses. The variation of the g-factor as a function of the Na/(Na+Li) ratio presents a minimum around (x=0.5). The composition non-linearity behavior of Tg, vibration bending mode, and g-factor are signature of the mixed alkali effect in the glasses.

description: Manganese-based MXenes are promising two-dimensional materials due to the broad palette of their magnetic phases and the possibility of experimental preparation because the corresponding MAX phase was already prepared. Here, we systematically investigated geometrical conformers and spin solutions of oxygen-terminated Mn$_2$C MXene and performed subsequent many-body calculations to obtain reliable electronic and optical properties. Allowing energy-lowering using the correct spin ordering via supercell magnetic motifs is essential for the Mn$_2$CO$_2$ system. The stable ground-state Mn$_2$CO$_2$ conformation is antiferromagnetic (AFM) one with zigzag lines of up and down spins on Mn atoms. The AFM nature is consistent with the parent MAX phase and even the clean depleted Mn$_2$C sheet. Other magnetic states and geometrical conformations are energetically very close, providing state-switching possibilities in the material. Subsequent many-body GW and Bethe-Salpeter equation (BSE) calculations provide indirect semiconductor characteristics of AFM Mn$_2$CO$_2$ with a fundamental gap of 2.1 eV (and a direct gap of 2.4 eV), the first bright optical transition at 1.3 eV and extremely strongly bounded (1.1 eV) first bright exciton. Mn$_2$CO$_2$ absorbs efficiently the whole visible light range and near ultraviolet range (between 10 - 20%).
