description: Gamma-ray burst (GRB) afterglows are powerful probes for studying the different properties of their host galaxies (e.g., the interstellar dust) at all redshifts. By fitting their spectral energy distribution (SED) over a large range of wavelengths, we can gain direct insights into the properties of the interstellar dust by studying the extinction curves. Unlike the dust extinction templates, such as the average Milky Way (MW) or the Small and Large Magellanic Cloud (SMC and LMC), the extinction curves of galaxies outside the Local Group exhibit deviation from these laws. Altogether, X-ray and gamma-ray satellites as well as ground-based telescopes, such as Neil Gehrels Swift Observatory (Swift) and Gamma-Ray Optical and Near-Infrared Detector (GROND), provide measurements of the afterglows from the X-ray to the NIR, which can be used to extract information on dust extinction curves along their lines of sight. The study presented in this paper undertakes such a photometric study, comprising a preparatory work for the SVOM mission and its ground-based follow-up telescope COLIBRI. We propose a simple parameterization of the dust extinction curve of GRB host galaxies. Our model is based on a power law form with the addition of a Loretzian-like Drude profile with two parameters: the extinction slope, $γ$, and the 2175 $Å$ bump amplitude, $E_\rm{b}$. Using the seven GROND filter bands, we tested our dust extinction model and explored the parameter space in extinction and redshift by fitting SEDs of simplified simulations of GRB afterglow spectra based on different extinction curve templates. From a final sample of 10 real Swift/GROND extinguished GRBs, we determined the quantities of the dust extinction in their host and measured their extinction curves. The measured average extinction curve is equivalent to a quasi-featureless in-between SMC-LMC template.

description: Magnetotransport properties of ferromagnetic semiconductor (Ga,Mn)As have been investigated. Measurements at low temperature (50 mK) and high magnetic field (<= 27 T) have been employed in order to determine the hole concentration p = 3.5x10^20 cm ^-3 of a metallic (Ga0.947Mn0.053)As layer. The analysis of the temperature and magnetic field dependencies of the resistivity in the paramagnetic region was performed with the use of the above value of p, which gave the magnitude of p-d exchange energy |N0beta | ~ 1.5 eV.

description: Segmentation of infected areas in chest X-rays is pivotal for facilitating the accurate delineation of pulmonary structures and pathological anomalies. Recently, multi-modal language-guided image segmentation methods have emerged as a promising solution for chest X-rays where the clinical text reports, depicting the assessment of the images, are used as guidance. Nevertheless, existing language-guided methods require clinical reports alongside the images, and hence, they are not applicable for use in image segmentation in a decision support context, but rather limited to retrospective image analysis after clinical reporting has been completed. In this study, we propose a self-guided segmentation framework (SGSeg) that leverages language guidance for training (multi-modal) while enabling text-free inference (uni-modal), which is the first that enables text-free inference in language-guided segmentation. We exploit the critical location information of both pulmonary and pathological structures depicted in the text reports and introduce a novel localization-enhanced report generation (LERG) module to generate clinical reports for self-guidance. Our LERG integrates an object detector and a location-based attention aggregator, weakly-supervised by a location-aware pseudo-label extraction module. Extensive experiments on a well-benchmarked QaTa-COV19 dataset demonstrate that our SGSeg achieved superior performance than existing uni-modal segmentation methods and closely matched the state-of-the-art performance of multi-modal language-guided segmentation methods.

description: We compare gap equation predictions for the spontaneous breaking of global symmetries in supersymmetric Yang-Mills theory to nonperturbative results from holomorphic effective action techniques. In the theory without matter fields, both approaches describe the formation of a gluino condensate. With $N_f$ flavors of quark and squark fields, and with $N_f$ below a certain critical value, the coupled gap equations have a solution for quark and gluino condensate formation, corresponding to breaking of global symmetries and of supersymmetry. This appears to disagree with the newer nonperturbative techniques, but the reliability of gap equations in this context and whether the solution represents the ground state remain unclear.

description: Phytomedicine as an alternative to conventional medications which become more interested for researcher. Moringa Oleifera (M. Oleifera) has been used for centuries to cure a range of illnesses. M. Oleifera, commonly known as the miracle tree, ben oil tree, and drumstick tree, is a Moringaceae family plant whose latin name is Moringa oleifera Lam. It has a high concentration of macro and micronutrients, as well as other bioactive components, all of which are necessary for the body’s correct function and the prevention of different disorders. The plant’s leaves, seeds, and blooms are all edible and offer a variety of medicinal benefits. Moringa is used to treat diabetes, bacterial, viral, and fungal infections, inflammation, heart disease, cancer, and joint pain. Numerous studies of Moringa oleifera have emphasised its phytochemical components, future possibilities, and usefulness in a variety of domains, including ethnomedicine, whereas this review is a collection of previous discoveries and an update on all previous work.

description: Change detection has been a hotspot in remote sensing technology for a long time. With the increasing availability of multi-temporal remote sensing images, numerous change detection algorithms have been proposed. Among these methods, image transformation methods with feature extraction and mapping could effectively highlight the changed information and thus has better change detection performance. However, changes of multi-temporal images are usually complex, existing methods are not effective enough. In recent years, deep network has shown its brilliant performance in many fields including feature extraction and projection. Therefore, in this paper, based on deep network and slow feature analysis (SFA) theory, we proposed a new change detection algorithm for multi-temporal remotes sensing images called Deep Slow Feature Analysis (DSFA). In DSFA model, two symmetric deep networks are utilized for projecting the input data of bi-temporal imagery. Then, the SFA module is deployed to suppress the unchanged components and highlight the changed components of the transformed features. The CVA pre-detection is employed to find unchanged pixels with high confidence as training samples. Finally, the change intensity is calculated with chi-square distance and the changes are determined by threshold algorithms. The experiments are performed on two real-world datasets and a public hyperspectral dataset. The visual comparison and quantitative evaluation have both shown that DSFA could outperform the other state-of-the-art algorithms, including other SFA-based and deep learning methods.

description: The standard approach for constructing a phylogenetic tree from a set of sequences consists of two key stages. First, Multiple Sequence Alignment (MSA) of the sequences is computed. The aligned data is then used to reconstruct the phylogenetic tree. The accuracy of the final tree heavily relies on the quality of MSA. Consequently, obtaining an accurate MSA is critical for improving the accuracy of the phylogenetic information. The accuracy of MSA decreases with sequence divergence. Numerous studies have demonstrated the difficulty in obtaining good MSA for reconstructing deep phylogeny, e.g. arthropod phylogeny. The accuracy of MSA is universally recognized as the limiting factor for tracing evolutionary history back in time. In this thesis, we assess the effect of guide tree on the accuracy of Multiple Sequence Alignment and subsequent phylogenetic tree and apply 3-way alignment to generate more accurate guide trees. We evaluate the performance of MAFFT on simulated dataset with different level of divergency including highly diverged sequences. Our results show that 3-way alignment outperforms the MAFFT's default method in generating more accurate guide trees specially for highly diverged sequences. Moreover, MSAs generated by using 3-way alignment guide trees lead to more accurate subsequent phylogenetic trees compared to MSAs generated by MAFFT default method. In addition, we showed the significant role of a good guide tree in improving final phylogenetic trees. Finally, our results emphasis on the significantly low performance of MAFFT in aligning highly diverged sequences.

description: Space situation awareness (SSA) includes tracking of active and inactive resident space objects (RSOs) and assessing the space environment through sensor data collection and processing. To enhance SSA, the dynamic data-driven applications systems (DDDAS) framework couples on-line data with off-line models to enhance system performance. Using feedback control, sensor management, and communications reliability. For information management, there is a need for identity authentication and access control to ensure the integrity of exchanged data as well as to grant authorized entities access right to data and services. Due to decentralization and heterogeneity of SSA systems, it is challenging to build an efficient centralized access control system, which could either be a performance bottleneck or the single point of failure. Inspired by the blockchain and smart contract technology, this paper introduces BlendCAC, a decentralized authentication and capability-based access control mechanism to enable effective protection for devices, services and information in SSA networks. To achieve secure identity authentication, the BlendCAC leverages the blockchain to create virtual trust zones and a robust identity-based capability token management strategy is proposed. A proof-of-concept prototype has been implemented on both resources-constrained devices and more powerful computing devices, and is tested on a private Ethereum blockchain network. The experimental results demonstrate the feasibility of the BlendCAC scheme to offer a decentralized, scalable, lightweight and fine-grained access control solution for space system towards SSA.

A precessing stellar disk model for superorbital modulations of the gamma-ray binary LS I+61$^{\circ}$ 303

description: Gamma-ray binary LS I+61$^{\circ}$ 303 consists of a neutron star orbiting around a Be star with a period of $P_{\rm orb}\simeq26.5\ {\rm d}$. Apart from orbital modulations, the binary shows long-term flux variations with a superorbital period of $P_{\rm sup}\simeq4.6\ {\rm yrs}$ as seen in nearly all wavelengths. The origin of this superorbital modulation is still not well understood. Under the pulsar wind-stellar outflow interaction scenario, we propose that the superorbital modulations of LS I+61$^{\circ}$ 303 could be caused by the precession of the Be disk. Assuming X-rays arise from synchrotron radiation of the intrabinary shock, we develop an analytical model to calculate expected flux modulations over the orbital and superorbital phases. The asymmetric two-peak profiles in orbital light curves and sinusoidal-like long-term modulations are reproduced under the precessing disk scenario. The observed orbital phase drifting of the X-ray peak and our fitting of long-term X-ray data indicate that the neutron star is likely orbiting around the star with a small eccentricity and periastron phase around $Φ_{\rm p}\sim0.6$. We compare the Corbet diagrams of LS I+61$^{\circ}$ 303 with other Be/X-ray binaries and the linear correlation in the $P_{\rm sup}-P_{\rm orb}$ diagram suggests that the precession of the Be disk in LS I+61$^{\circ}$ 303 is induced by the tidal torque of its neutron star companion.

 Note— Tranzscheliella helutae is a part of T. hypodytes species complex. Tranzscheliella helutae is the only species from this genus occurring on Agropyron (subfamily Pooideae, tribe Triticeae). Agropyron contains about seven species found in temperate, mostly arid regions of Eurasia (Dewey 1986). Several species of Agropyron were listed as hosts of T. hypodytes s.l. by Vánky (2012). Tranzscheliella helutae has slightly larger and darker spores than T. hypodytes s.str. (4–4.5 × 4.5–5.5 μm). The spores of T. helutae are unevenly, and moderately verruculose in SEM, which differ from the densely, minutely, uniformly verruculose spores of T. hypodytes s.str. In the phylogenetic analysis, specimens of T. helutae were resolved in a well-supported monophyletic clade (Fig. 1). In a concatenated alignment there are 25 base pair differences between T. helutae and the most closely related species, T. yupeitaniae.

description: In a simple framework which naturally incorporates dark matter stability and neutrino phenomenology, we compute all the possible texture zeros which arise when the non-abelian flavor symmetry A4 is spontaneously broken to Z2. As a result, we obtain four textures with two vanishing matrix elements. Two of such textures predict a zero contribution to the neutrinoless double beta decay effective mass parameter at tree level, and as a one loop bound we get $m_{ee}<8\times 10^{-2}$ meV. These are compatible with the normal ordering for the neutrino masses and the allowed range for the lightest neutrino mass is between $m_{ν_{min}}\sim3$ meV and $m_{ν_{max}}\sim8$ meV. Additionally we obtain dark matter stability linked to the way the flavor symmetry is broken, leaving a residual Z2 symmetry

description: At energies much less than the electron mass $m$ the effects of quantum fluctuations in the vacuum due to virtual electron loops can be included by extending the Maxwell Lagrangian by additional non-renormalizable terms corresponding to the Uehling and Euler-Heisenberg interactions. This effective field theory is used to calculate the properties of the QED vacuum at temperatures $T << m$. By a redefinition of the electromagnetic field, the Uehling term is shown not to contribute. The Stefan-Boltzmann energy density is thus found to be modified by a term proportional with $T^8/m^4$ in agreement with the semi-classical result of Barton. The speed of light in blackbody radiation is smaller than one. Similarly, the correction to the energy density of the vacuum between two metallic parallel plates diverges like $1/m^4z^8$ at a distance from one of the plates $z \to 0$. While the integral of the regularized energy density is thus divergent, the regularized integral is finite and corresponds to a correction to the Casimir force which varies with the separation $L$ between the plates as $1/m^4L^8$. This result is in seemingly disagreement with a previous result for the radiative correction to the Casimir force which gives a correction varying like $1/mL^5$ in a calculation using full QED.

The chemical structures and absolute configurations of these compounds were determined using HR-ESI-MS, spectroscopic data, and electronic circular dichroism. Notably, compounds (1-5) are dimeric quinones that share the same benzisochromanquinone moiety, specifically identified as 7-dehydroxyventiloquinone H (6), which was the first time to report as a natural product. Compounds 1-2 and compounds 4-5 are two pairs of atropisomers respectively.

We determine analytically the autocorrelation function A(t). This is done by computing generalized first-passage type probabilities P_n(t) which measure the fraction of space crossed by exactly n interfaces during the time interval (0,t), and then expressing the autocorrelation function via P_n's. We further reveal the spatial structure of the system by analyzing the domain size distribution.

description: To observe the dynamical Casimir effect (DCE) induced by a moving mirror is a long-standing challenge because the mirror velocity needs to approach the speed of light. Here, we present an experimentally feasible method for observing this mechanical DCE in an optomechanical system. It employs a detuned, parametric driving to squeeze a cavity mode, so that the mechanical mode, with a typical resonance frequency, can parametrically and resonantly couple to the squeezed cavity mode, thus leading to a resonantly amplified DCE in the squeezed frame. The DCE process can be interpreted as {\it mechanically-induced two-photon hyper-Raman scattering} in the laboratory frame. Specifically, {\it a photon pair} of the parametric driving absorbs a single phonon and then is scattered into an anti-Stokes sideband. We also find that the squeezing, which additionally induces and amplifies the DCE, can be extremely small. Our method requires neither an ultra-high mechanical-oscillation frequency (i.e., a mirror moving at nearly the speed of light) nor an ultrastrong single-photon optomechanical coupling and, thus, could be implemented in a wide range of physical systems.

description: Cynoglossum L. is a taxonomically difficult genus belonging to the Boraginaceae family, distributed in Asia, Europe, mainly in Turkey, and in the Mediterranean region. Plants of this genus are used against various diseases in the ethnomedicine of several countries. In the present study, the chemical composition of the essential oil was obtained from the hydrodistillation of aerial parts of the Sicilian accession of Cynoglossum clandestinum Desf. was analysed by GC and GC-MS. The main constituents of the essential oil were aldehydes and ketones (69.9%) with nonanal (18.9%), 4-sec-butoxy-2-butanone (18.1%), and 3-methyl-butanal (13.1%) as main metabolites. No one paper has been previously published on the essential oil of this species, and there is a lack of studies also in the near related genera. The aim of this work is in fact, to study a species that has never been investigated, and through this, try to help place it within the Boraginaceae family.

description: We study the effects of a uniform magnetic field on the one-dimensional spin-orbital model in terms of effective field theories. Two regions are examined: one around the SU(4) point (J=K/4) and the other with K<K/4, the excitation spectrum has a gap. When the magnetic field is beyond some critical value, a quantum phase transition occurs. However, the correlation functions around the SU(4) point and the region with K<

description: We present a general method to compute the nonlinear matter power spectrum for dark energy and modified gravity scenarios with percent-level accuracy. By adopting the halo model and nonlinear perturbation theory, we predict the reaction of a $Λ$CDM matter power spectrum to the physics of an extended cosmological parameter space. By comparing our predictions to $N$-body simulations we demonstrate that with no-free parameters we can recover the nonlinear matter power spectrum for a wide range of different $w_0$-$w_a$ dark energy models to better than 1% accuracy out to $k \approx 1 \, h \, {\rm Mpc}^{-1}$. We obtain a similar performance for both DGP and $f(R)$ gravity, with the nonlinear matter power spectrum predicted to better than 3% accuracy over the same range of scales. When including direct measurements of the halo mass function from the simulations, this accuracy improves to 1%. With a single suite of standard $Λ$CDM $N$-body simulations, our methodology provides a direct route to constrain a wide range of non-standard extensions to the concordance cosmology in the high signal-to-noise nonlinear regime.

We apply this formula to the problem of the correct q\bar{q} assignment for the scalar meson nonet. Our results strongly favor the masses of the scalar isoscalar mostly octet and mostly singlet states in the vicinity of 1.45 GeV and 1.1 GeV, respectively

description: Aviation is recognized as one of the top advanced technology sectors in Europe and generates innovation that benefits society at large far beyond its direct operational sphere. Environmental protection is and will continue to be a key driver for the aviation industry as a whole. Meeting community expectations on aircraft noise, engine emission and fuel/energy consumption has always presented a challenge to aircraft and engine manufacturers and to those involved in airport planning and air traffic management. The paper describes the current points of the EU civil aviation on a way to FlightPath 2050 Challenge 3 goals, defined in PARE project at initial stage.

description: Crotalaria burhia (Family: Fabaceae) is an important medicinal plant widely distributed in arid parts of the world, including Pakistan, India, and Afghanistan. This plant has enormous ethnobotanical values and is used to treat various common ailments such as swelling, infections, cancer, hydrophobia, pain and skin diseases. Moreover, it is also utilised as food for goats, to make sheds for animals and as a suitable soil binder. This review article is an attempt to analyse critically and to provide updated and categorised information about C. burhia including comprehensive knowledge of the botanical description, traditional/folklore uses, phytochemistry, pharmacological/biological potential, and to facilitate scientific basis for future work. The phytochemical studies (qualitative and quantitative) on C. burhia have indicated the presence of important phytochemical classes, namely alkaloids, flavonoids, glycosides, saponins, phenolics, tannins, steroids, and terpenoids. Pharmacological studies such as anti-inflammatory/analgesic, antioxidant, anti-microbial, anti-tumour, anti-nociceptive, enzyme inhibition, and termiticidal activities were reported from different parts of this plant. Most of the bioassays from this plant have been done on the crude extract. Minimal information about the phytochemicals (responsible for biological activities), except a few compounds has been reported. The potential chemical compounds may need to be purified and tested for the biological potential from isolated compounds in future.
Energy transduction in periodically driven non-Hermitian systems

description: We show a new mechanism to extract energy from non-equilibrium fluctuations typical of periodically driven non-Hermitian systems. The transduction of energy between the driving force and the system is revealed by an \emph{anomalous} behavior of the susceptibility, leading to a diminution of the dissipated power and consequently to an improvement of the transport properties. The general framework is illustrated by the analysis of some relevant cases.

Quasi-1D ultracold rigid-rotor collisions : reactive and non-reactive cases

description: We study polar alkali dimer scattering in a quasi-1D geometry for both reactive and non-reactive species. Elastic and reactive rates are computed as a function of the amplitude of a static electric field within a purely long-range model with suitable boundary conditions at shorter range. We describe the diatomic molecules as rigid rotors and results are compared to the fixed-dipole approximation. We show in particular that for molecules with a sufficiently strong induced dipole moment oriented perpendicular to the trap axis, the long-range repulsive interaction leads to the suppression of short-range processes. Such shielding effect occurs for both reactive and non-reactive molecules, preventing two-body reactions as well as losses due to "sticky processes" [Phys. Rev. A 85, 062712 (2012)] from occurring. The present results demonstrate the possibility to suppress loss rates in current ultracold molecule experiments using 1D confinement.

description: We experimentally demonstrate a variation on a Sisyphus cooling technique that was proposed for cooling antihydrogen. In our implementation, atoms are selectively excited to an electronic state whose energy is spatially modulated by an optical lattice, and the ensuing spontaneous decay completes one Sisyphus cooling cycle. We characterize the cooling efficiency of this technique on a continuous beam of Sr, and compare it with radiation pressure based laser cooling. We demonstrate that this technique provides similar atom number for lower end temperatures, provides additional cooling per scattering event and is compatible with other laser cooling methods. This method can be instrumental in bringing new exotic species and molecules to the ultracold regime.

Confusion2Vec: Towards Enriching Vector Space Word Representations with Representational Ambiguities

description: Word vector representations are a crucial part of Natural Language Processing (NLP) and Human Computer Interaction. In this paper, we propose a novel word vector representation, Confusion2Vec, motivated from the human speech production and perception that encodes representational ambiguity. Humans employ both acoustic similarity cues and contextual cues to decode information and we focus on a model that incorporates both sources of information. The representational ambiguity of acoustics, which manifests itself in word confusions, is often resolved by both humans and machines through contextual cues. A range of representational ambiguities can emerge in various domains further to acoustic perception, such as morphological transformations, paraphrasing for NLP tasks like machine translation etc. In this work, we present a case study in application to Automatic Speech Recognition (ASR), where the word confusions are related to acoustic similarity. We present several techniques to train an acoustic perceptual similarity representation ambiguity. We term this Confusion2Vec and learn on unsupervised-generated data from ASR confusion networks or lattice-like structures. Appropriate evaluations for the Confusion2Vec are formulated for gauging acoustic similarity in addition to semantic-syntactic and word similarity evaluations. The Confusion2Vec is able to model word confusions efficiently, without compromising on the semantic-syntactic word relations, thus effectively enriching the word vector space with extra task relevant ambiguity information. We provide an intuitive exploration of the 2-dimensional Confusion2Vec space using Principal Component Analysis of the embedding and relate to semantic, syntactic and acoustic relationships. The potential of Confusion2Vec in the utilization of uncertainty present in lattices is demonstrated through small examples relating to ASR error correction.
Long Wavelength Anomalous Diffusion Mode in the 2D XY Dipole Magnet

description: In 2D XY ferromagnet the dipole force induces a strong interaction between spin-waves in the long-wavelength limit. The major effect of this interaction is the transformation of a propagating spin-wave into a diffusion mode. We study the anomalous dynamics of such diffusion modes. We find that the Janssen-De Dominics functional, which governs this dynamics, approaches the non-Gaussian fixed-point. A spin-wave propagates by an anomalous anisotropic diffusion with the dispersion relation: $iω{\sim}k_{y}^{Δ_y}$ and $iω{\sim}k_{x}^{Δ_x}$, where ${Δ_y}=47/27$ and ${Δ_x}=47/36$. The low-frequency response to the external magnetic field is found.

description: Comparison of this study vs. Nevers et al. [50] and Amos [20]. Comparison of findings of this study to phylogenetic analysis data by Nevers et al. [50] and Amos [20]. Species examined in both this study and at least one of the previous two are shown with the number of each Tektin class, and total number of Tektins found in each study. As the Nevers et al. [50] study used presence/absence data, a ‘+’ indicates presence while ‘0’ represents absence. Totals for Nevers et al. [50] are based on assumption that a ‘+’ is equal to one homolog. * indicates that different species from the same genus are compared. ** indicates different species from the same order or family are compared. *** indicates at least one Tektin did not group with any of the five recognized Tektins. † indicates that Nevers et al. [50] identified additional Tektin homologs that our study was unable to find. †† indicates the special case of human Tektins reported in Amos [20] (see Discussion). Green background indicates the previous study found the same number of Tektins as our study but with one or more misclassified. Red background indicates that the previous study found a different number of Tektins than our study. (PDF 660 kb)
