description: Real-estate image tagging is one of the essential use-cases to save efforts involved in manual annotation and enhance the user experience. This paper proposes an end-to-end pipeline (referred to as RE-Tagger) for the real-estate image classification problem. We present a two-stage transfer learning approach using custom InceptionV3 architecture to classify images into different categories (i.e., bedroom, bathroom, kitchen, balcony, hall, and others). Finally, we released the application as REST API hosted as a web application running on 2 cores machine with 2 GB RAM. The demo video is available here.

description: While not detected yet, pairs of exoplanets in the 1:1 mean motion resonance probably exist. Low eccentricity, near-planar orbits, which in the comoving frame follow the horseshoe trajectories, are one of the possible stable configurations. Here we study transit timing variations produced by mutual gravitational interaction of planets in this orbital architecture, with the goal to develop methods that can be used to recognize this case in observational data. In particular, we use a semi-analytic model to derive parametric constraints that should facilitate data analysis. We show that characteristic traits of the transit timing variations can directly constrain the (i) ratio of planetary masses, and (ii) their total mass (divided by that of the central star) as a function of the minimum angular separation as seen from the star. In an ideal case, when transits of both planets are observed and well characterized, the minimum angular separation can also be inferred from the data. As a result, parameters derived from the observed transit timing series alone can directly provide both planetary masses scaled to the central star mass.

Textual manuscript
Stage performance

description: Some of Lope de Vega’s comedies, those witnessed by an autograph manuscript, are of undeniable interest, as they provide the opportunity to observe closely the author’s work of composition which resulted in the text to be sold to the company for the representation. The present article focuses on the specific case of El piadoso aragonés, dated August 17, 1626, whose manuscript is preserved at the National Library of Madrid. On the one hand, the study of the autograph allows to observe the changes made in itinere by the author during the final draft of the text, analyzing the processes through which the playwright shaped the textual material in order to reach the final version of the play. These changes reveal some of the compositional techniques of Lope: the autograph bears traces of the genesis of the text and constitute a significant proof of the author’s work on his play. Moreover, the manuscript – which was used for at least three different representations during the seventeenth century by the company of Antonio de Prado – presents some textual signs (mainly omissions, but also additions and corrections) that permit to determine which version of the comedy was the one represented in that period. Starting from a thorough analysis of the autograph, the article examines the life of the text through the various adjustments made for the mise en scène during the Siglo de Oro, establishing the methods and the reasons for the changes in the version of the play attributed to the autor de comedia, the actor-manager.

description: According to the data of quasi-vertical sounding at Usolie-Tory path (midpoint - 52.3N, 103E, 120km distance), the dynamics of vertical structure of the midscale inhomogeneities of the plasma frequency was reconstructed. These irregularities are caused by Tohoku earthquake 11/03/2011 (38.3N, 142.4E). Observed horizontal velocities of propagation in the ionosphere and the spatial scales of the wave-like disturbance modes, generated by earthquakes, are calculated. As a result of numerical simulation involving the data from TALAYA seismic station (TLY, 51.7N, 103.7E) and comparison with the experiment it is shown that the vertical ionospheric irregularities of 5-40km range observed in first 20 minutes after the beginning of observations of effects (from 06:00 to 06:20 UT) are qualitatively explained by travelling of acoustic shock wave cone ( Mach cone ) from supersonic ground source - seismic wave to the heights up to 200km. It is shown that the most likely source of the shock wave were Z and E components of the seismic oscillations observed at TLY station. Irregularities observed after 06:20UT were apparently linked with other mechanisms. It is shown that the existing temporary CHIRP ionosonde temporal resolution (60 seconds) and the ionogram inversion technique used are not enough for detailed diagnosis of fine spatial vertical structures of this process.

description: The composition of phenolic compounds of ethanolic extract taken from mesocarp and exocarp parts of Citrus maxima and Citrus sinensis peels cultivated in Iran have been identified. The Phenolic compounds in ethanolic extracts were quantified using HPLC-DAD. Different amounts of phenolic compounds were detected in the samples including hesperidin, t-ferulic acid, catechin, sinapic acid, vanillin, chlorogenic acid and caffeic acid. The most represented compound in both plants was hesperidin. It was the main phenolic compound detected in both exocarp and mesocarp parts of both species, with the maximum amount belonging to mesocarp of C. sinensis. The average amount of hesperidin detected in mesocarp and exocarp of C. maxima was 15.04 and 7.42 mg g−1 dry weight, while it was 17.34 and 7.63 mg g−1 dry weight for C. sinensis.

description: The bayesTFR package for R provides a set of functions to produce probabilistic projections of the total fertility rates (TFR) for all countries, and is widely used, including as part of the basis for the UN's official population projections for all countries. Liu and Raftery (2020) extended the theoretical model by adding a layer that accounts for the past TFR estimation uncertainty. A major update of bayesTFR implements the new extension. Moreover, a new feature of producing annual TFR estimation and projections extends the existing functionality of estimating and projecting for five-year time periods. An additional autoregressive component has been developed in order to account for the larger autocorrelation in the annual version of the model. This article summarizes the updated model, describes the basic steps to generate probabilistic estimation and projections under different settings, compares performance, and provides instructions on how to summarize, visualize and diagnose the model results.

description: Preliminary results from an ongoing project to compute a grid of post-AGB models is presented. Our preliminary results show that stellar evolution computations that include an updated treatment of the microphysics predict post-AGB timescales that are several times shorter that predicted by older models. Also the mass-luminosity relation of post-AGB models deviates from that of older grids. In addition, our results suggest only a slight metallicity dependence of the post-AGB timescales. We expect these results to have significant consequences for models of the formation of planetary nebulae and their luminosity function.

The odd chromatic number of a planar graph is at most 8

description: Petruševski and Škrekovski \cite{odd9} recently introduced the notion of an odd colouring of a graph: a proper vertex colouring of a graph $G$ is said to be \emph{odd} if for each non-isolated vertex $x \in V(G)$ there exists a colour $c$ appearing an odd number of times in $N(x)$. Petruševski and Škrekovski proved that for any planar graph $G$ there is an odd colouring using at most $9$ colours and, together with Caro \cite{oddremarks}, showed that $8$ colours are enough for a significant family of planar graphs. We show that $8$ colours suffice for all planar graphs.

description: We study the x-ray emission following the collision of a Bi$^{83+}$ ion with a neutral Xe atom at the projectile energy 70 MeV/u. The collisional and post-collisional processes are treated separately. The probabilities of various many-electron processes at the collision are calculated within a relativistic independent electron model using the coupled-channel approach with atomic-like Dirac-Fock-Sturm orbitals. The analysis of the post-collisional processes resulting in the x-ray emission is based on the fluorescence yields, the radiation and Auger decay rates, and allows to derive intensities of the x-ray emission and compare them with experimental data. A reasonable agreement between the theoretical results and the recent experimental data is observed. The role of the relativistic effects is investigated.

description: Congenital cystic adenomatoid malformation (CCAM) is a rare congenital lung lesion. It may appear since birth (30-35%) with difficulty breathing or may have a late onset (60- 65%) with recurring pulmonary infections or growth failure; in a small percentage of cases, the lesion can be completely asymptomatic. Fetal or post-natal surgery can be used as surgical treatment of these lesions. Postnatal surgery consists of a lobectomy, bilobectomy or pneumonectomy, based on the size of the lesion. The best age to undergo this surgery is around 2 years, but only if the injury is stable and the child has no complications. The study describes three cases of CCAM, observed at the Pediatric Surgery Section of the University of Siena. We analyzed those 3 cases whose approach was defined by the onset of symptoms, age and clinical condition of patients. In the first case the surgery was performed a few hours after birth due to the worsening of the clinical conditions; in the other two cases it was delayed because the patients were asymptomatic. The purpose of this study is to review the management of patients with CCAM in relation to clinical onset and the type of injury.

description: In this manuscript, we propose a new sensing mechanism to enhance the sensitivity of a quantum system to nonlinearities by homodyning the amplitude quadrature of the cavity field. The system consists of two dissipatively coupled cavity modes, one of which is subject to single- and two-photon drives. In the regime of low two-photon driving strength, the spectrum of the system acquires a real spectral singularity. We find that this singularity is very sensitive to the two-photon drive and nonlinearity of the system, and compared to the previous nonlinearity sensor, the proposed sensor achieves an unprecedented sensitivity around the singularity point. Moreover, the scheme is robust against fabrication imperfections. This work would open a new avenue for quantum sensors, which could find applications in many fields, such as the precise measurement and quantum metrology.

description: Implementation of orbital-free free-energy functionals in the Profess code and the coupling of Profess with the Quantum Espresso code are described. The combination enables orbital-free DFT to drive ab initio molecular dynamics simulations on the same footing (algorithms, thermostats, convergence parameters, etc.) as for Kohn-Sham (KS) DFT. All the non-interacting free-energy functionals implemented are single-point: the local density approximation (LDA; also known as finite-T Thomas-Fermi, ftTF), the second-order gradient approximation (SGA or finite-T gradient-corrected TF), and our recently introduced finite-T generalized gradient approximations (ftGGA). Elimination of the KS orbital bottleneck via orbital-free methodology enables high-T simulations on ordinary computers, whereas those simulations would be costly or even prohibitively time-consuming for KS molecular dynamics (MD) on very high-performance computer systems. Example MD simulations on H over a temperature range 2,000 K <= T <=4,000,000 K are reported, with timings on small clusters (16-128 cores) and even laptops. With respect to KS-driven calculations, the orbital-free calculations are between a few times through a few hundreds of times faster.

On Some Quantitative Unique Continuation Properties of Fractional Schrödinger Equations: Doubling, Vanishing Order and Nodal Domain Estimates
Creators: name: Rüland, Angkana
Publisher: name: arXiv
Year: 2014
Subjects: subject: Analysis of PDEs (math.AP)

description: In this article we determine bounds on the maximal order of vanishing for eigenfunctions of a generalized Dirichlet-to-Neumann map (which is associated with fractional Schrödinger equations) on a compact, smooth Riemannian manifold, $(M,g)$, without boundary. Moreover, with only slight modifications these results generalize to equations with $C^1$ potentials. Here Carleman estimates are a key tool. These yield a quantitative three balls inequality which implies quantitative bulk and boundary doubling estimates and hence leads to the control of the maximal order of vanishing. Using the boundary doubling property, we prove upper bounds on the $\mathcal{H}^{n-1}$-measure of nodal domains of eigenfunctions of the generalized Dirichlet-to-Neumann map on analytic manifolds.

description: Experimentally [1-38] and computationally [39-50] validated machine learning (ML) articles are sorted based on the size of the training data: 1-100, 101-10000, and 10000+ in a comprehensive set summarizing legacy and recent advances in the field. The review emphasizes the interrelated fields of synthesis, characterization, and prediction. Size range 1-100 consists mostly of Bayesian optimization (BO) articles, whereas 101-10000 consists mostly of support vector machine (SVM) articles. The articles often use combinations of ML, feature selection (FS), adaptive design (AD), high-throughput (HiTp) techniques, and domain knowledge to enhance predictive performance and/or model interpretability. Grouping cross-validation (G-CV) techniques curb overly optimistic extrapolative predictive performance. Smaller datasets relying on AD are typically able to identify new materials with desired properties but do so in a constrained design space. In larger datasets, the low-hanging fruit of materials optimization is typically already discovered, and the models are generally less successful at extrapolating to new materials, especially when the model training data favors a particular type of material. The large increase of ML materials science articles that perform experimental or computational validation on the predicted results demonstrates the interpenetration of materials informatics with the materials science discipline and an accelerating materials discovery for real-world applications.

description: Two-dimensionally extended amorphous carbon ("amorphous graphene") is a prototype system for disorder in 2D, showing a rich and complex configurational space that is yet to be fully understood. Here we explore the nature of amorphous graphene with an atomistic machine-learning (ML) model. We create structural models by introducing defects into ordered graphene through Monte-Carlo bond switching, defining acceptance criteria using the machine-learned local, atomic energies associated with a defect, as well as the nearest-neighbor (NN) environments. We find that physically meaningful structural models arise from ML atomic energies in this way, ranging from continuous random networks to paracrystalline structures. Our results show that ML atomic energies can be used to guide Monte-Carlo structural searches in principle, and that their predictions of local stability can be linked to short- and medium-range order in amorphous graphene. We expect that the former point will be relevant more generally to the study of amorphous materials, and that the latter has wider implications for the interpretation of ML potential models.
title:  Iranian Foreign Policy Shedding the Pariah Image
Creators: name: Gleason Jr., Joseph Edward
Publisher: name: Old Dominion University Libraries
Year: 1993

description: This study analyzes Iranian foreign policy since 1979 to determine if Iran is a pariah state in the international community. To determine Iran's isolation in the international community, various factors were examined, including diplomatic relations, political leverage, relations with the United Nations, and the ability to acquire military hardware. Iran's status was compared with three generally accepted pariah states, Taiwan, Israel, and South Africa to determine the degree of isolation faced by the Islamic Republic. This study determined that Iran remains a pariah state, but is less isolated than most pariah states because its objectionable behavior, its aggressive foreign policy, effects a limited number of states. Additionally, the study determined that Iran, unlike many pariah states, can shed its pariah image without substantially affecting its population, territory, or form of government. Major factors contributing to Iran's pariah status are: Tehran's support of militant Islamist groups and anti-Western terrorist organizations, a recent build-up of offensive weapons, a program to develop nuclear weapons, and aggression in the Gulf. Sources of documentation for this study consist of speeches, printed interviews, and policy statements by Iranian and Arab officials and reports by Iranian and Arab newspapers, United Nations reports and resolutions, statements by US officials before congress, official US policy statements, reports in various US newspapers, and articles in scholarly journals.

description: To date, most numerical simulations of molecular clouds, and star formation within them, assume a uniform density sphere or box with an imposed turbulent velocity field. In this work, we select molecular clouds from galactic scale simulations as initial conditions, increase their resolution, and re-simulate them using the SPH code Gadget2. Our approach provides clouds with morphologies, internal structures, and kinematics that constitute more consistent and realistic initial conditions for simulations of star formation. We perform comparisons between molecular clouds derived from a galactic simulation, and spheres of turbulent gas of similar dimensions, mass and velocity dispersion. We focus on properties of the clouds such as their density, velocity structure and star formation rate. We find that the inherited velocity structure of the galactic clouds has a significant impact on the star formation rate and evolution of the cloud. Our results indicate that, although we can follow the time evolution of star formation in any simulated cloud, capturing the entire history is difficult as we ignore any star formation that might have occurred before initialisation. Overall, the turbulent spheres do not match the complexity of the galactic clouds.

description: In this paper, we will prove the global existence of solutions to the three dimensional axially symmetric Prandtl boundary layer equations with small initial data, which lies in $H^1$ Sobolev space with respect to the normal variable and is analytical with respect to the tangential variables. Proof of the main result relies on the construction of a tangentially weighted analytic energy functional, which acts on a specially designed good unknown. The constructed energy functional can find its two dimensional parallel in Ignatova-Vicol [2016ARMA] where no tangential weight is introduced and the specially good unknown is set to control the lower bound of the analytical radius, whose two dimensional similarity can be traced to Paicu-Zhang [2021ARMA]. Our result is an improvement of that in Ignatova-Vicol [2016ARMA] from the almost global existence to the global existence and an extension of that in Paicu-Zhang [2021ARMA] from the two dimensional case to the three dimensional axially symmetric case.

description: We present new determinations of the iron abundance for 220 stars belonging to the stellar system Terzan 5 in the Galactic bulge. The spectra have been acquired with FLAMES at the Very Large Telescope of the European Southern Observatory and DEIMOS at the Keck II Telescope. This is by far the largest spectroscopic sample of stars ever observed in this stellar system. From this dataset, a subsample of targets with spectra unaffected by TiO bands was extracted and statistically decontaminated from field stars. Once combined with 34 additional stars previously published by our group, a total sample of 135 member stars covering the entire radial extent of the system has been used to determine the metallicity distribution function of Terzan 5. The iron distribution clearly shows three peaks: a super-solar component at [Fe/H]$\simeq0.25$ dex, accounting for 29% of the sample, a dominant sub-solar population at [Fe/H]$\simeq-0.30$ dex, corresponding to 62% of the total, and a minor (6%) metal-poor component at [Fe/H]$\simeq-0.8$ dex. Such a broad, multi-modal metallicity distribution demonstrates that Terzan 5 is not a genuine globular cluster but the remnant of a much more complex stellar system.

description: This paper is devoted to study the geodesic structure of regular Hayward black hole. The timelike and null geodesic have been studied explicitly for radial and non-radial motion. For timelike and null geodesic in radial motion there exists analytical solution, while for non-radial motion the effective potential has been plotted, which investigates the position and turning points of the particle. It has been found that massive particle moving along timelike geodesics path are dragged towards the BH and continues move around BH in particular orbits.

description: Genus Calophyllum from the family of Calophyllaceae is an evergreen broad-leaved tree that is endemic to Southeast Asia, especially Malaysia. They have been reported for various ethnomedicinal uses in traditional medicine. Previous studies of Malaysian Calophyllum species revealed them to be a rich source of bioactive phytoconstituents such as xanthones, coumarins, terpenoids, and chromanone acids. To date, the extracts and compounds from Malaysian Calophyllum species have shown a broad spectrum of pharmacological activities. For example, calanolide A, a coumarin isolated from Malaysian C. lanigerum, has now reached clinical development to become an anti-HIV drug. This article presents an overview of the significant phytochemical and pharmacological activities of Malaysian Calophyllum species to aid researchers in further discovery of potential benefits of various species of this genus.

description: Vaccinium ashei Reade, popularly known as Rabbiteye blueberry, has several therapeutic properties attributed to the phenolic compounds present in its leaves and fruits. Here, we sought to evaluate the effects of the hydroalcoholic extract from V. ashei leaves (Bluegem cultivar, VAB) in T-cell Acute lymphoblastic leukemia (T-ALL). The VAB extract was toxic to T-ALL cells at the ∼60 µg/ml concentration. T-ALL cell death occurred through apoptosis. VAB extract was found to induce micronuclei formation, p53 pathway activation, and cell cycle arrest. Those mutagenic effects were evidenced through microscopy analysis and molecular p53 pathway activation. A series of phenolic compounds were identified in VAB extract by mass spectrometry, such as vanillic acid, catechin, caffeic acid, chlorogenic acid, rutin, coumaric acid, taxifolin, quercetin and naringenin, some of which are presumed to induce DNA damage. In conclusion, the V. ashei leaves extract may have important secondary metabolites with antileukemic properties.
