description: Ocular pathology detection from fundus images presents an important challenge on health care. In fact, each pathology has different severity stages that may be deduced by verifying the existence of specific lesions. Each lesion is characterized by morphological features. Moreover, several lesions of different pathologies have similar features. We note that patient may be affected simultaneously by several pathologies. Consequently, the ocular pathology detection presents a multi-class classification with a complex resolution principle. Several detection methods of ocular pathologies from fundus images have been proposed. The methods based on deep learning are distinguished by higher performance detection, due to their capability to configure the network with respect to the detection objective. This work proposes a survey of ocular pathology detection methods based on deep learning. First, we study the existing methods either for lesion segmentation or pathology classification. Afterwards, we extract the principle steps of processing and we analyze the proposed neural network structures. Subsequently, we identify the hardware and software environment required to employ the deep learning architecture. Thereafter, we investigate about the experimentation principles involved to evaluate the methods and the databases used either for training and testing phases. The detection performance ratios and execution times are also reported and discussed.

description: Photoabsorption cross sections of small sodium cluster cations (Na$_n^+$, n=3,5,7 and 9) were calculated at various temperatures with the time-dependent local-density-approximation (TDLDA) in conjunction with ab initio molecular dynamics simulations, yielding spectra that agree with measured ones without ad-hoc line broadening or renormalization. Three thermal line-broadening mechanisms are revealed: (I) lifting of level degeneracies caused by symmetry-breaking ionic motions, (II) oscillatory shifts of the entire spectrum caused by breathing vibrations, and (III) cluster structural isomerizations.

The Eclipsing Binary BG Geminorum: Improved Constraints on the Orbit and the Structure of the Accretion Disk

Publisher: name: arXiv

description: We describe new optical photometric and spectroscopic observations of the semi-detached eclipsing binary BG Geminorum. A large change in the amount of Mg I absorption at secondary maximum indicates the presence of cool material in the outer edge of the disk surrounding the unseen primary star. Detection of weak He I emission implies a hot radiation source at the inner edge of the disk. If the velocity variations in the Hbeta emission line track the orbital motion of the primary star, the primary star has an orbital semiamplitude of K1 = K(Hbeta) = 16.0 +- 4.6 km/sec. This result yields a mass ratio, q = 0.22 +- 0.07, consistent with the q = 0.1 derived from the large ellipsoidal variation. Despite this progress, the nature of the primary star - B-type star or black hole - remains uncertain.

description: This study investigated the potential of delivering an anti-glaucoma drug using commercial silicone hydrogel (SiHy) contact lenses. The moderately hydrophobic drug latanoprost was rapidly loaded in 4 min by swelling contact lenses in a solution of the drug in n-propanol. A fraction of the drug was radiolabeled, thus allowing measurement of the uptake and subsequent release of drug into artificial tear fluid. Three questions were addressed: (1) how much drug can be loaded into each type of lens, (2) how fast is drug release, and (3) how are these values related to the contact lens chemistry. The results showed that much more latanoprost could be loaded into SiHy lenses than a conventional contact lens of poly(hydroxyethyl methacrylate). The drug uptake correlated with the amount of swelling in n-propanol, with Galyfilcon lenses having the greatest swelling and highest drug uptake. The drug release from the SiHy lenses occurred over days, whereas the conventional lens released nearly all drug in a burst over a few hours. To examine correlations between lens chemistry, drug chemistry and uptake, and solvent chemistry, the Hansen solubility parameters were calculated using estimates of contact lens chemistry. These results showed that drug uptake in SiHy lenses correlated with favorable solubility parameter interactions between the n-propanol and the lens material, but did not correlate with interactions between the drug and the lens materials.

description: High Energy Neutrino may lead to a New High Energy Astronomy. Neutrino interaction in matter at PeVs- EeVs may behave differently from Standard Model predictions because possible TeV Gravity scenario. While traditional km^3 neutrino underground detector will be uneasy to disentangle the Gravity TeV scenario any new Horizontal Tau Air-Shower detectors at PeVs tau energy, beyond Mountain Chains, will be greatly enhanced and it may probe fruit-fully the New TeV Physics imprint. Moreover observing upcoming and horizontal tau air-showers {UPTAUS, HORTAUS} from high mountains toward Mount Chains or along widest Earth Crust crown masses at the Horizons edges, Ultra High Energy,UHE, nu_{tau} and its consequent tau lepton decay in flight, will greatly amplify any single UHE nu_{tau} track and it will test, at highest energies, huge volumes comparable to underground km^3 ones; observing UPTAUS and HORTAUs from higher balloons or satellites at orbit altitudes, at GZK energies, the Horizontal Crown effective Masses may even exceed 150 km^3. These Highest energies (10^{19} eV) nu astronomy are tuned to test the needed abundant nu fluence in GZK Z-Showering model: in this scenario ZeV Ultra High Energy neutrino are hitting on relic light (0.1-5 eV masses) anti-neutrinos, clustered in dark hot halos, creating UHE Z bosons whose decay in flight may be the hadronic secondaries observed on Earth atmosphere as UHECR, isotropically spread along the cosmic edges and clustered toward few correlated BL Lac sources.

description: The monotonicity-based approach has become one of the fundamental methods for reconstructing inclusions in the inverse problem of electrical impedance tomography. Thus far the method has not been proven to be able to handle extreme inclusions that correspond to some parts of the studied domain becoming either perfectly conducting or perfectly insulating. The main obstacle has arguably been establishing suitable monotonicity principles for the corresponding Neumann-to-Dirichlet boundary maps. In this work, we tackle this shortcoming by first giving a convergence result in the operator norm for the Neumann-to-Dirichlet map when the conductivity coefficient decays to zero and/or grows to infinity in some given parts of the domain. This allows passing the necessary monotonicity principles to the limiting case. Subsequently, we show how the monotonicity method generalizes to the definite case of reconstructing either perfectly conducting or perfectly insulating inclusions, as well as to the indefinite case where the perturbed conductivity can take any values between, and including, zero and infinity.

description: Given an elliptic fibration $f \colon X \to S$ over the spectrum of a complete discrete valuation ring with algebraically closed residue field, we use a Hochschild--Serre spectral sequence to express the torsion in $R^1f_\ast \mathscr{O}_X$ as the first group cohomology $H^1(G,H^0(S^\prime, \mathscr{O}_{S^\prime}))$. Here, $G$ is the Galois group of the maximal extension $K^\prime / K$ such that the normalization of $X \times_S S^\prime$ induces an étale covering of $X$, where $S^\prime$ is the normalization of $S$ in $K^\prime$. The case where $S$ is a Dedekind scheme is easily reduced to the local case. Moreover, we generalize to higher-dimensional fibrations.

description: The South Pole Imaging Fabry-Perot Interferometer (SPIFI) is the first instrument of its kind -- a direct-detection imaging spectrometer for astronomy in the submillimeter band. SPIFI's focal plane is a square array of 25 silicon bolometers cooled to 60 mK; the spectrometer consists of two cryogenic, scanning Fabry-Perot interferometers in series with a 60 mK bandpass filter. The instrument operates in the short submillimeter windows (350 microns, 450 microns) available from the ground, with spectral resolving power selectable between 500 and 10000. At present, SPIFI's sensitivity is within a factor 1.5-3 of the photon background limit, comparable to the best heterodyne spectrometers. The instrument's large bandwidth and mapping capability provide substantial advantages for specific astrophysical projects, including deep extragalactic observations. In this article we present the motivation for and design of SPIFI and its operational characteristics on the telescope.

The redox properties of the compounds were investigated by cyclic voltammetry. The predicted structures and charge distribution patterns of the compounds were obtained by DFT calculations and NBO analysis. The geometrical parameters in these optimized structures are in good agreement with the average values obtained for analogs from the CSD database. The theoretical studies confirm presence of a strong resonance in the cyclotriphosphazene ring. Finally, the ability of the three new derivatives to interact with ten selected biomacromolecules (BRAF kinase, CatB, DNA gyrase, HDAC7, rHA, RNR, TrxR, TS, Top II, B-DNA) was investigated by docking calculations and compared with that of doxorubicin.

description: ``Dimension bubbles'' of the type previously studied by Blau and Guendelman [S.K. Blau and E.I. Guendelman, Phys. Rev. D40, 1909 (1989)], which effectively enclose a region of 5d spacetime and are surrounded by a region of 4d spacetime, can arise in a 5d theory with a compact extra dimension that is dimensionally reduced to give an effective 4d theory. These bubbles with thin domain walls can be stabilized against total collapse in a rather natural way by a scalar field which, as in the case with ``ordinary'' nontopological solitons, traps light scalar particles inside the bubble.

description: This paper seeks to understand the effect of crop insurance and direct payments on farm survival and growth, and how this effect differs by the economic size of the farm. Using data from the Agricultural Censuses of 2007 and 2012, along with additional county-level data, we estimate a three stage model that accounts for sample selection bias and the endogeneity of the choice to purchase crop insurance. We also control for characteristics of the principal operator, farm household, and farm operation. Our preliminary results show that government policies in place over the period from 2007 to 2012 played a small but important role in the survival and growth of US commercial farms.

description: The (p,$γ$) cross sections of three stable Sr isotopes have been measured in the astrophysically relevant energy range. These reactions are important for the $p$-process in stellar nucleosynthesis and, in addition, the reaction cross sections in the mass region up to 100 are also of importance concerning the $rp$-process associated with explosive hydrogen and helium burning. It is speculated that this $rp$-process could be responsible for a certain amount of $p$-nuclei in this mass region. The (p,$γ$) cross sections of $^{84,86,87}$Sr isotopes were determined using an activation technique. The measurements were carried out at the 5 MV Van de Graaff accelerator of the ATOMKI, Debrecen. The resulting cross sections are compared with the predictions of statistical model calculations. The predictions are in good agreement with the experimental results for $^{84}$Sr(p,$γ$)$^{85}$Y whereas the other two reactions exhibit differences that increase with mass number. The corresponding astrophysical reaction rates have also been computed.

GNSS slant TEC

description: The ionosphere is a highly variable medium known to affect microwave signals, such as those transmitted by GNSS satellites. GNSS data from ground-based receivers are routinely analyzed to model the global Total Electron Content (TEC). Since most of the ionosphere’s TEC originates from altitudes between 300 and 500 km, TEC observations collected from ground-based receivers are too far away to provide insight into the three-dimensional electron density. Low Earth Orbiting (LEO) satellites equipped with GNSS receivers are an essential tool to separate between bottom-side TEC and top-side TEC. Given a sufficiently good observational geometry, the LEO satellites can help reconstruct the three-dimensional electron density. In the past, we have developed a Kalman-Filter data assimilation scheme to obtain the electron density from LEO slant TEC observations. This works well for altitude above the LEO satellites but not as well for the bottom side since the observational geometry is relatively poor. Several studies investigated the impact of LEO for Positioning Navigation and Timing (PNT) to improve observational geometry. These satellites are equipped with a GNSS receiver and a transmitter to improve the observational geometry for ground-based receivers, especially in urban or mountain areas, where a lot of signal shadowing occurs. The ground-to-LEO links also help to improve observational geometry on the bottom-side ionosphere. to his study, we will investigate the potential of ground-to-LEO links for ionosphere reconstruction. For that purpose, we will assume that the currently used LEO satellites for topside reconstruction, namely Swarm, GRACE-FO, Jason-3, Sentinel 1/2/3, COSMIC-2, and Spire, would transmit GNSS-like signals that can be tracked by the IGS network. We will show results from closed-loop simulations using synthetic data from IRI-2020. We will furthermore investigate which orbits or constellations are preferable to improve the coverage by the LEO satellites.

description: In the United States, the social cost of carbon (SCC) is one of the foremost tools for calibrating the socially optimal approach for climate change policy. The SCC is estimated using climate-economic models with implicit temperature-damage relationships. Given the vast uncertainty surrounding climate impacts, meta-analyses of global climate damage estimates are a key tool for determining the relationship between temperature and climate damages, so as to communicate the current state of knowledge to model developers. Using a larger dataset than previously assembled in the literature, this paper highlights several methodological improvements that address bias present in previous meta-analyses of the temperature-damage relationship. Specifically, due to limited data availability, previous meta-analyses of global climate damages potentially suffered from multiple sources of bias: duplication bias, measurement error, omitted variable bias, and publication bias. By expanding our dataset (to include additional published and grey literature estimates), including methodological variables, and correcting the specification of temperature (to account for different reference periods), we are able to address and test for these biases. Estimating the relationship between temperature and climate damages using weighted least squares with cluster robust standard errors at the model level, we find strong evidence of duplicate bias. Using these results as an input in the DICE model – to update the DICE damage function – we determine that duplication and omitted variable bias significantly impact the damage-temperature relationship in past meta-analyses and the resulting SCC estimates. Focusing exclusively on non-catastrophic climate impacts, we find that the temperature-damage relationship estimated in Nordhaus and Sztorc (2013) is biased downwards by approximately 179% to 264%, depending on how climate change’s impacts on productivity are treated. This implies a downward bias in DICE’s SCC estimate by 203% to 314%, depending on the treatment of productivity. If we also consider catastrophic impacts, the potential bias in the SCC increases to 344% to 469%.

description: It can be difficult to understand how wines prices are established. Wines are experience goods, so consumers must rely on their previous experience or expert opinions in making their purchase choices. The impact of expert rating scores on wine prices is well documented. This study estimates the contribution of expert’s wine tasting notes, focusing on certain keywords, and other wine characteristics. We examine whether expert descriptive information has an influence on the wine prices using tasting notes on Washington wines that are listed in Wine Spectator magazine. The analysis includes estimations of different wine segments by price category. Estimating a hedonic price functions by product segment relaxes the assumption that the implicit prices of each attribute are the same across price categories. The results indicate that certain keywords used in tasting notes and wine characteristics exert a significant influence on the prices of wines and these effects are different across different segments.

description: The current debate about the nature of the carbonaceous material carrying the infrared (IR) emission spectra of planetary and proto-planetary nebulae, including the broad plateaus, calls for further studies on the interplay between structure and spectroscopy of carbon-based compounds of astrophysical interest. The recent observation of C60 buckminsterfullerene in space suggests that carbon clusters of similar size may also be relevant. In the present work, broad statistical samples of C60 isomers were computationally determined without any bias using a reactive force field, their IR spectra being subsequently obtained following local optimization with the density-functional-based tight-binding theory. Structural analysis reveals four main structural families identified as cages, planar polycyclic aromatics, pretzels, and branched. Comparison with available astronomical spectra indicates that only the cage family could contribute to the plateau observed in the 6-9 micron region. The present framework shows great promise to explore and relate structural and spectroscopic features in more diverse and possibly hydrogenated carbonaceous compounds, in relation with astronomical observations.

description: In this paper we fix our attention, on hadron structure, and show that also the strong interaction strength alpha_S, ordinarily called the "(perturbative) coupling--constant square}", can be evaluated within our theory, and found to decrease (increase) as the "distance" r decreases (increases). This yields both the confinement of the hadron constituents, and their asymptotic freedom: in qualitative agreement with the experimental evidence. In other terms, our approach leads us, on a purely theoretical ground, to a dependence of alpha_S on r which had been previously found only on phenomenological and heuristic grounds. We expect the above agreement to be also quantitative, on the basis of a few checks performed in this work.

description: This paper attempts to determine whether negative personal attitudes toward welfare may prevent eligible persons from applying for food stamps. Using the dataset from the 2002 National Survey of American families (NSAF) survey, a logistic regression model was run. The findings of this study indicate that negative attitudes towards welfare may prevent people from applying for food stamps. Food insecurity on the other hand, increases the likelihood of applying for food stamps. Demographic variables such as employment, education and marital status also influence the probability of applying for food stamps.

description: We report on the analysis of high-speed multicolor photometry of the eclipsing X-ray binary X1822-371. We used new eclipse timings to derive a revised optical ephemeris. A quadratic fit to the eclipse timings is not statistically significant but suggests that the orbital period is increasing on a timescale of P/|Pdot|= (4.2 +/- 1.4) 10^6 yr. We find no systematic delay or advance of the optical timings with respect to the X-ray timings. Average UBVRI light curves show the deep eclipse of the disc by the secondary star superimposed on the broader and shallower occultation of the inner disc regions by the outer disc (dip), and an orbital hump centred at phase +0.25 which is mostly seen in the U and B bands. The starting phase of the dip occurs earlier for shorter wavelengths, while the egress occurs at the same phase in all bands. This suggests that the thickening of the outer, occulting disc rim is gradual with azimuth at ingress but decreases sharply at egress. We fit synthetic photometry to the extracted colors of the inner and outer disc regions to estimate their effective temperatures. We find Teff= (9+/-5) 10^7 K and Teff= (6+/-2) 10^4 K, respectively, for the inner and outer disc regions. The orbital dependency of the flickering activity is derived from the mean scatter of the individual light curves with respect to the average UBVRI light curves. The flickering curves show a broad eclipse at the dipping phases, the depth of which decreases with increasing wavelength. The blue, eclipsed flickering component is associated with the inner disc regions and can be fitted by a blackbody spectrum of Teff= (2.1+/-0.8) 10^8 K, whereas the uneclipsed flickering component probably arises from the outermost disc regions and is well described by a blackbody of Teff= (9.6+/-0.7) 10^3 K.

description: In this paper, a novel water-based reconfigurable frequency selective rasorber (FSR) at microwave band is proposed, which has a thermally tunable absorption band above the transmission band. The water-based FSR consists of a bandpass type frequency selective surface (FSS) and a 3D printing container. The water substrate is filled into the sealed space constructed by the above two structures. The numerical simulation results show that the FSR can achieve absorption with high absorptivity from 8.3 to 15.2 GHz, and obtain a transmission band of 5.2 to 7.0 GHz. The minimum insertion loss of the transmission band reaches 0.72 dB at 6.14 GHz. In addition, the FSR has the reconfigurable characteristics of absorbing or reflecting electromagnetic waves by filling with water or not. The proposed water-based FSR shows its good transmission/absorption performance under different polarizations and oblique incident angles. Due to the Debye model of water, the absorption band can be adjusted by water temperature, while the passband remains stable. At last, prototype of the FSR based on water has been fabricated, and the experimental results are presented to demonstrate the validity of the proposed structure.

description: A closed contact manifold is called Besse when all its Reeb orbits are closed, and Zoll when they have the same minimal period. In this paper, we provide a characterization of Besse contact forms for convex contact spheres and Riemannian unit tangent bundles in terms of $S^1$-equivariant spectral invariants. Furthermore, for restricted contact type hypersurfaces of symplectic Euclidean spaces, we give a sufficient condition for the Besse property via the Ekeland-Hofer capacities.

description: The Vessel Traffic Service (VTS) systems belong to the fundamental tools used in ensuring a high level of safety across sea basins with heavy traffic, where the presence of navigational hazards poses a great risk of collision or a ship running aground. In order to determine the mutual location of ships, VTS systems obtain information from different facilities, such as coastal radar stations, AIS, and vision systems. Fixing a ship’s position is always accompanied by a degree of error, but the degree of error depends on the specific position fixing system used. In order to increase the accuracy of position fixing in VTS systems, the authors propose the use of contemporary geodetic methods. The article presents the theoretical fundamentals of two unconventional geodesic methods of estimation: M estimation and Msplit(q)estimation and the authors’ own proposal of their application in VTS systems. The article concludes with a test verifying theoretical assumptions, performed with the use of a computer application allowing position fixing with the use of selected robust adjustment methods. Furthermore, an example is presented of Msplit(q)estimation as used for the acquisition of low-signal radar echoes, which in VTS systems are not automatically identified for tracking. The level of the echo signal makes it difficult for a VTS controller to separate these objects from typical radar noise and interference.

description: Much work in computer science has adopted competitive analysis as a tool for decision making under uncertainty. In this work we extend competitive analysis to the context of multi-agent systems. Unlike classical competitive analysis where the behavior of an agent's environment is taken to be arbitrary, we consider the case where an agent's environment consists of other agents. These agents will usually obey some (minimal) rationality constraints. This leads to the definition of rational competitive analysis. We introduce the concept of rational competitive analysis, and initiate the study of competitive analysis for multi-agent systems. We also discuss the application of rational competitive analysis to the context of bidding games, as well as to the classical one-way trading problem.
