description: In the present work surface roughness of copper samples after mechanical surface preparation processes (polishing, grinding, sand-blasting) and after exposure in non-oxidizing (high purity argon) and oxidizing (air) conditions at 700 and 750°C have been evaluated by contact profilometer and by fractal analysis. Quantitative description of surfaces that are hidden from the sight of conventional methods is possible by fractal analysis, e.g. in the present work, the roughness of Cu2O/Cu boundary has been evaluated under oxide layer. It has been pointed out, that in both oxidizing and non-oxidizing conditions initial surface roughness of copper is affected by annealing at high temperature: at 700°C surface roughness of polished and ground samples increased but at 750°C decreased in comparison to surface roughness prior to heat treatment. For sand-blasted samples in both oxidizing and non-oxidizing conditions the lowest values of surface roughness parameters were obtained at 750°C. It is then concluded that two phenomena are responsible for such effect: chemical reaction between copper and oxygen and surface diffusion of copper due to high temperature of annealing.

description: One of the most common forms of cancer in the United States is skin cancer. Although the incidence of skin cancer is increasing annually, the distribution of skin cancer risk is not the same everywhere. Compared with urban residents, rural residents, who are typically older, less educated, and poorer than urban residents, have less access to early cancer detection programs and preventative health information. This study used data from a project designed to prevent cancers caused by obesity, tobacco, and sunburn in rural communities. Data were collected from 382 randomly selected residents of two rural communities in Texas in 2011. The information collected included demographic characteristics, attitudes and behaviors regarding cancer prevention, general health knowledge and anthropometric measurements (height, weight, and waist circumference). Ordinal logistic regression analyses and Chi-square tests were used to examine the associations of factors affecting sunscreen use and sunburn frequency. This study found that rural residents, who are Hispanic, smokers, and obese were less likely to use sunscreen. Those who are obese, unmarried, and less educated were reported more frequent sunburn. Knowledge derived from this study could be used to determine the need and scope of future skin cancer risk intervention efforts for rural residents.

description: A standard microstrip patch antenna has narrow bandwidth thus making it inappropriate for many wireless communication systems. Therefore in this paper we present imprinting of Hilbert curve slot on patch antenna to analyze its effects on the bandwidth. Multiple iterations of Hilbert curve are being implemented and relationship between the iterations and bandwidth is studied. It is observed that increase in iteration will result in increase in bandwidth. As the number of iterations increase the total area of the slot decreases, whereas the length of the slot remain the same within the area. The simulated result depicts that -10 dB bandwidth is achieved at 2.4 GHz which is the operable frequency of WLAN and Bluetooth.

description: Magnetic resonance imaging (MRI) is a widely used medical imaging modality. However, due to the limitations in hardware, scan time, and throughput, it is often clinically challenging to obtain high-quality MR images. The super-resolution approach is potentially promising to improve MR image quality without any hardware upgrade. In this paper, we propose an ensemble learning and deep learning framework for MR image super-resolution. In our study, we first enlarged low resolution images using 5 commonly used super-resolution algorithms and obtained differentially enlarged image datasets with complementary priors. Then, a generative adversarial network (GAN) is trained with each dataset to generate super-resolution MR images. Finally, a convolutional neural network is used for ensemble learning that synergizes the outputs of GANs into the final MR super-resolution images. According to our results, the ensemble learning results outcome any one of GAN outputs. Compared with some state-of-the-art deep learning-based super-resolution methods, our approach is advantageous in suppressing artifacts and keeping more image details.

On the relation between the IR continuum and the active galactic nucleus in Seyfert galaxies

description: A sample of the brightest known Seyfert galaxies from the CfA sample is analyzed on the basis of ISO photometric and spectroscopic data. Regardless of the Seyfert type, the mid-IR continuum emission from these galaxies is found to be correlated with the coronal line emission arising in the nuclear active region. Conversely, the correlation degrades progressively when moving from the mid- to the far-IR emission, where it ends to vanish. It is concluded that the mid-IR emission is largely dominated by dust heated by processes associated with the active nucleus whereas the far-IR is a different component most probably unrelated with the active region. We suggest that the far-IR component is due to dust heated by the stellar population in the disks of these galaxies.

(Figs 6; 12E-G)
Resembling Gossia diversifolia except that much to most of the blade itself is conduplicate, and it lacks the winged branchlets of G. diversifolia.
TYPUS. — New Caledonia. Grande Terre, North Prov., Poindimié, 165°19’59.988’’E, 20°56’36.996’’S, 4.VIII.1967, MacKee 17222 (holo-, P [missing]; iso-, P[P00781068], BISH[fragment], NOU[- NOU029074], WELTU).
REPRESENTATIVE HERBARIUM SPECIMEN. — P00781068.
ETYMOLOGY. — In reference to the partially to strongly folded (conduplicate) leaf blades.
DISTRIBUTION, HABITAT AND PHENOLOGY. — Known only from the type collection at or near Poindimié (Fig. 6) in humid forests at 50 meters. Flowering unknown; fruiting in April.
DESCRIPTION
Shrubs
To 3 m.
Branchlets
Terete; internodes> 5 mm.
Leaves
Coriaceous, 2 per node; petioles 1.5-2.5 mm, flattened to broadly sulcate above; blades 2.0-3.0 × 1.2-2.0 cm, ovate, base rounded but conspicuously conduplicate above petiole (up to or more than half the length), surface moderately to strongly undulate, apex acute, midnerve above flush to slightly sulcate, secondary veins not raised above, oil glands absent from lower surface.
Inflorescence
A monad or simple cyme, axillary and terminal, sometimes nodding apically; extrafloral bracts absent.
Bracteoles
c. 1 mm, narrowly elliptic, glabrous.
Hypanthium
c. 3 × 3 mm, campanulate, surface smooth, glabrous.
Calyx
Lobes 4(-5), 1.2-2.2 mm, broadly rounded, glabrous above and below, green.
Petals
Unknown.
Filaments
Not seen, estimate of c. 80.
Style
Not seen; ovary apex sparsely hairy.
Fruit
4.5-5.5 × 4.5-5.5 mm, globular, base rounded, green (immature) to red (mature); seed 1.
REMARKS
This poorly known species is diagnosed by its strongly conduplicate leaves with undulate margins, and efforts to relocate it should be a high priority. The calyx lobes in fruit are reflexed in the one known specimen, unlike the more common condition of ascending to erect lobes. The similar species G. diversifolia has winged branchlets. Gossia conduplicata sp. nov. differs from G. bourailensis sp. nov. by its more undulate leaf margin and narrowly acute leaf apex. The base of the leaf blade in Gossia katepahiensis can be conduplicate, but only slightly so. The type specimen of Gossia diversifolia was collected from Balade, farther north along the eastern coast from Poindimié, the one known locality of G. conduplicata sp. nov. Further study is needed to better understand the differences of these two taxa.

description: Interdisciplinary research has been conducted in the frame of the Helmholtz Virtual Institute for Gasification Technology (HVIGasTech). The main objective is to develop a validated numerical simulation tool for describing the entrained flow gasification of biomass (cf. bioliq process). This paper presents work-in-progress and reports the recent experimental and numerical results for the entrained flow gasification of model fuels (ethylene glycol, 90 % ethylene glycol + 10 % wood-char) under atmospheric conditions. Three experimental campaigns have been carried out at the Research Entrained flow GAsifier (REGA). Radial profiles of gas phase composition ($\text{CH}_4$, $\text{CO}$, $\text{CO}_\text{2}$, $\text{H}_2$) and temperature have been measured at burner distances of 300 mm and 680 mm. In parallel to the experimental campaigns, RANS based simulations have been performed using ANSYS Fluent. Turbulence-chemistry interaction has generally been described by the Eddy Dissipation Concept (EDC). EDC has been used in combination with two global reaction mechanisms for the entrained flow gasification of ethylene glycol: the HVI1 mechanism and the extended Jones-Lindstedt mechanism. Devolatilisation and the heterogeneous reactions of wood-char with $\text{CO}_\text{2}$ and $\text{H}_\text{2}\text{O}$ are computed using kinetics derived from measurements. The numerical results for the entrained flow gasification of ethylene glycol show good agreement with the measured data. In particular, the model based on EDC and the HVI1 mechanism predicts the gas composition well. Gas temperatures are slightly overpredicted. The numerical results for the gasification of slurry deviate from the experimental results concerning the gas phase composition. Further research needs to be carried out to close this gap.
Effect of interstellar objects on metallicity of low-mass first stars formed in a cosmological model

description: We investigate metal pollution onto the surface of low-mass population III stars (Pop. III survivors) via interstellar objects floating in the Galactic interstellar medium. Only recently, Tanikawa et al. analytically estimated how much metal should collide to an orbiting Pop. III survivor encouraged by the recent discovery of 'Oumuamua and suggested that ISOs are the most dominant contributor of metal enrichment of Pop. III survivors. When we consider a distribution of interstellar objects in the Galactic disc, Pop. III survivors' orbits are significant properties to estimate the accretion rate of them though Tanikawa et al. assumed one modelled orbit. To take more realistic orbits into calculating the accretion rate, we use a high-resolution cosmological $N$-body simulation that resolves dark matter minihaloes. Pop. III survivors located at solar neighbourhood have a number of chances of ISO($> 100$ m) collisions, typically $5\times10^6$ times in the last $5$ Gyr, which is one order of magnitude greater than estimated in the previous study. When we assume a power-law parameter $α$ of the ISO cumulative number density with size greater than $D$ as $n \propto D^{-α}$, $0.80 \, M_{\odot}$ stars should be typically polluted [Fe/H]$\sim -2$ for the case of $α=2.0$. Even in the cases of $0.70$ and $0.75 \, M_{\odot}$ stars, the typical surface metallicity are around [Fe/H]$=-6 \sim -5$. From the presence of stars with their [Fe/H], we can constrain on the lower limit of the power $α$, as $α\gtrsim 2.0$, which is consistent with $α$ of km-size asteroids and comets in the solar system. Furthermore, we provide six candidates as the ISO-polluted Pop. III stars in the case of $α\sim 2.5$. Metal-poor stars so far discovered are possible to be metal-free Pop. III stars on birth.

description: We study the prospects for three-dimensional mapping of the dark matter to high redshift through the shearing of faint galaxies images at multiple distances by gravitational lensing. Such maps could provide invaluable information on the nature of the dark energy and dark matter. While in principle well-posed, mapping by direct inversion introduces exceedingly large, but usefully correlated noise into the reconstruction. By carefully propagating the noise covariance, we show that lensing contains substantial information, both direct and statistical, on the large-scale radial evolution of the density field. This information can be efficiently distilled into low-order signal-to-noise eigenmodes which may be used to compress the data by over an order of magnitude. Such compression will be useful for the statistical analysis of future large data sets. The reconstructed map also contains useful information on the localization of individual massive dark matter halos, and hence the dark energy from halo number counts, but its extraction depends strongly on prior assumptions. We outline a procedure for maximum entropy and point-source regularization of the maps that can identify alternate reconstructions.

 Not Hetairus zebra Makarov, 1935: 319, fig. 1; = Hetairus fasciatus Kobyakova, 1936; western Pacific species.
 Diagnosis. Rostrum narrow, reaching at most to end of first segment of antennular peduncle, with 2–5 dorsal teeth, 1–2 on carapace proper, no ventral teeth. First segment of antennular peduncle with 2–4 spines on dorsal margin, appressed mesioventral spine, second and third segments with dorsal spines, stylocerite not reaching end of spine of second article. Carapace with strong supraorbital tooth, suborbital lobe, strong antennal tooth, small pterygostomian tooth. Third maxilliped with epipod but no exopod. Pereopods 1–3 with epipods. Pereopods 3–5 slender, with stout spinose dactyls. Merus of pereopods 3–5 without spines. Pleura of abdominal somites 1–3 rounded, 4, 5 with small points. Telson with 4 or 5 pairs dorsolateral spines, blunt apex. Total length 49 mm.
 Color in life. Conspicuously banded with brownish red to orange stripes on body, appendages (Leim 1921).
 Habitat and depth. Rocky subtidal areas, 10–140 m.
 Range. Gulf of St. Lawrence to Isles of Shoals, Maine; Bering Sea, Vancouver I. to off Santa Rosa I., California. Type locality not specified. Leim's material came from Passamaquoddy Bay, St. Croix River and Campobello I., New Brunswick and St. Mary's Bay, Nova Scotia.
 Remarks. Apparently unaware of the name given to the Atlantic species, Makarov (1935) created a homonym when describing the North Pacific species. Koyakova (1936) re-named the Pacific species, but did not designate any distinctive features that would differentiate it from the Atlantic species. Hayashi (1992: 118, fig, 4) redescribed and illustrated L. fasciatus. Chace (1997: 45, 51) gave the synonymy of Hetairus zebra with Lebbeus fasciatus but did not cite the Atlantic Lebbeus zebra.
 Lebbeus zebra is known from very few Pacific specimens. The Pacific and Atlantic specimens of L. zebra are very similar in morphology and habitat. Williams (1984) noted that Atlantic and Pacific specimens differed in the shape of the rostrum, but other species of Lebbeus exhibit considerable variation in this feature. It is likely that L. fasciatus and L. zebra have been confused in the literature. The specimens from Santa Rosa I., California more closely resemble those from St. Mary's Bay, Nova Scotia than those from Vancouver I., British Columbia.

The derived test statistics should be useful for applied researchers faced with the increasing availability of panel information where not every individual or country is observed for the full time span. The test statistics proposed here are based on ordinary least-squares residuals and hence are computationally very simple.

description: We show that the band structure of a carbon nanotube (NT) can be dramatically altered by mechanical strain. We employ an atomic force microscope tip to simultaneously vary the NT strain and to electrostatically gate the tube. We show that strain can open a bandgap in a metallic NT and modify the bandgap in a semiconducting NT. Theoretical work predicts that bandgap changes can range between +100meV and -100meV per 1% stretch, depending on NT chirality, and our measurements are consistent with this predicted range.

description: The Higgs effective potential becomes unstable at approximately $10^{11}$ GeV, and if only standard model interactions are considered, the lifetime $τ$ of the electroweak vacuum turns out to be much larger than the age of the Universe $T_U$. It is well known, however, that $τ$ is extremely sensitive to the presence of unknown new physics: the latter can enormously lower $τ$. This poses a serious problem for the stability of our Universe, demanding for a physical mechanism that protects it from a disastrous decay. We have found that there exists a universal stabilizing mechanism that naturally originates from the nonminimal coupling between gravity and the Higgs boson. As this Higgs-gravity interaction necessarily arises from the quantum dynamics of the Higgs field in a gravitational background, this stabilizing mechanism is certainly present. It is not related to any specific model, being rather natural and universal as it comes from fundamental pillars of our physical world: gravity, the Higgs field, the quantum nature of physical laws.

description: We report on the discovery of Cepheids in the spiral galaxy NGC 2841, based on observations made with the Wide Field and Planetary Camera 2 on board the Hubble Space Telescope. NGC 2841 was observed over 12 epochs using the F555W filter, and over 5 epochs using the F814W filter. Photometry was performed using the DAOPHOT/ALLFRAME package. We discovered a total of 29 variables, including 18 high-quality Cepheids with periods ranging from 15 to 40 days. Period-luminosity relations in the V and I bands, based on the high-quality Cepheids, yield an extinction-corrected distance modulus of 30.74 +/- 0.23 mag, which corresponds to a distance of 14.1 +/- 1.5 Mpc. Our distance is based on an assumed LMC distance modulus of 18.50 +/- 0.10 mag (D = 50+/- 2.5 kpc) and a metallicity dependence of the Cepheid P-L relation of gamma (VI) = -0.2 +/- 0.2 mag/dex.

description: While demand for locally produced food has increased sharply in recent years, interest in supporting local food systems is rising among Federal, State, and local policymakers. This study explores the idea of endogenous hub location on the fresh produce value chains. To overcome limitations in the literature, we integrate the effect of economies of scale and production seasonality into our models. Three experimental models are designed to assess effect of the application of yearly, seasonal and monthly data on model solutions. We then make explicit comparisons between solutions of models. Although solved using the same method, the three models generate varying solutions and in many respects they lead to different conclusions.

description: We present here results on the composite luminosity functions of galaxies in the clusters of galaxies selected from the SDSS Cut and Enhance cluster catalog (CE; Goto et al. 2001). We construct the composite luminosity function in the five SDSS bands, u,g,r,i and z, using 204 CE clusters ranging from z=0.02 to z=0.25. We use photometric redshifts to construct composite luminosity functions. The robustness of the weighting scheme was tested using Monte Carlo simulation. We find the slope of composite LFs become flatter toward redder color band. Comparing with field LFs of SDSS (Blanton et al. 2001), cluster LFs have brighter characteristic magnitude and flatter slopes in g, r, i and z bands. These results are consistent with the hypothesis that the cluster LF has two distinct underlying populations i.e. the bright end of the LF is dominated by bright early types that follow a gaussian--like luminosity distribution, while the faint--end of the cluster LF is a steep power--law like function dominated by star--forming (bluer) galaxies. We also study the composite luminosity functions for early--type and late--type galaxies using profile fits, a concentration parameter and u-r color to classify galaxy morphology. The strong dependence of LF on galaxy morphology is found.The faint end slope of the LF is always flatter for early--type galaxies than late--type regardless of passband and methodology. These results are consistent with the hypothesis that the cluster region are dominated by bright elliptical galaxies.

description: We present a thermodynamically consistent model of a ternary fluid interacting with elastic membranes. Following a free-energy modelling approach and taking into account the thermodynamics laws, we derive the equations governing the ternary fluid flow and dynamics of the membranes. We also provide the numerical framework for simulating such fluid-structure interaction problems. It is based on the lattice Boltzmann method, employed for resolving the evolution equations of the ternary fluid in an Eulerian description, coupled to the immersed boundary method, allowing for the membrane equations of motion to be solved in a Lagrangian system. The configuration of an elastic capsule placed at a fluid-fluid interface is considered for validation purposes. Systematic simulations are performed for a detailed comparison with reference numerical results obtained by Surface Evolver, and the Galilean invariance of the proposed model is also proven. The proposed approach is versatile, and a wide range of geometries can be simulated. To demonstrate this, the problem of a capillary bridge formed between two deformable capsules is investigated here.

description: Investment in the production of advanced biofuel has been encouraged by the federal regulation which enacted the Renewable Fuel Standard (RFS). However, investments and production of advanced biofuel has been lower than expected in recent years, leading regulators to substantially reduce required volumes of advanced biofuel. Real option analysis is used to help explain why uncertainty has reduced investment in advanced biofuel and eroded the requirements put forth by USEPA. This study examines the effect of uncertainty and irreversibility on a second-generation biofuel investment while considering the volatility of Renewable Identification Number (RIN) price, conventional fuel price and their correlations by applying a two stochastic variable approach.
Remarks on the phenomenological Tsallis distributions and their link with the Tsallis statistics

description: From the Tsallis unnormalized (or Tsallis-2) statistical mechanical formulation, Büyükkiliç {\it et al.} [Phys. Lett. A 197, 209 (1995)] derived the expressions for the single-particle distribution functions (known as the phenomenological Tsallis distributions) for particles obeying the Maxwell-Boltzmann, Bose-Einstein and the Fermi-Dirac statistics using the factorization approximation. In spite of the fact that this paper was published long time ago, its results are still extensively used in many fields of physics, and it is considered that it was this paper that established the connection between the phenomenological Tsallis distributions and the Tsallis statistics. Here we show that this result is incorrect: the mistake lies in the fact that the probability distribution function was derived using the definition of the generalized expectation values (of the Tsallis-2 statistics), but the single-particle distribution function was calculated from this probability distribution using the standard definition of the expectation values of the Tsallis normalized (or Tsallis-1) statistics. Considering the definition of the expectation values which is consistent with the Tsallis-2 formulation, we have proved that the single-particle (classical and quantum) distribution functions in the factorization approximation differ from the phenomenological Tsallis distributions.

description: China introduced a systematic pork reserve program in 2009 to decrease pork price volatility. The price stabilization effectiveness of the reserve program is unknown. Two econometric procedures are used to analyze the effectiveness of the program in reducing pork price volatility. The first approach is an autoregressive conditionally heteroskedastic (ARCH) regression model estimated using monthly national average wholesale pork price data for January 2000 to July 2015. Price volatility is modeled as the difference in monthly price in consecutive months. The ARCH procedure controls for domestic production, consumer income and seasonality. A difference in difference (DD) regression procedure, compliments the ARCH procedure, to further investigate the relationship between the reserve policy and price volatility. Two DD analyses are conducted. The first analysis measures monthly price volatility in terms of absolute differences, and the second in absolute percentage change differences. Both the ARCH and DD approaches find that pork price volatility increased, not decreased, after the introduction of the reserve program.

description: We study the properties of photochemical hazes in super-Earths/mini-Neptunes atmospheres with particular focus on GJ1214b. We evaluate photochemical haze properties at different metallicities between solar and 10000$\times$solar. Within the four orders of magnitude change in metallicity, we find that the haze precursor mass fluxes change only by a factor of $\sim$3. This small diversity occurs with a non-monotonic manner among the different metallicity cases, reflecting the interaction of the main atmospheric gases with the radiation field. Comparison with relative haze yields at different metallicities from laboratory experiments reveals a qualitative similarity with our theoretical calculations and highlights the contributions of different gas precursors. Our haze simulations demonstrate that higher metallicity results into smaller average particle sizes. Metallicities at and above 100$\times$solar with haze formation yields of $\sim$10$\%$ provide enough haze opacity to satisfy transit observation at visible wavelengths and obscure sufficiently the H$_2$O molecular absorption features between 1.1 $μ$m and 1.7 $μ$m. However, only the highest metallicity case considered (10000$\times$solar) brings the simulated spectra into closer agreement with transit depths at 3.6 $μ$m and 4.5 $μ$m indicating a high contribution of CO/CO$_2$ in GJ1214b's atmosphere. We also evaluate the impact of aggregate growth in our simulations, in contrast to spherical growth, and find that the two growth modes provide similar transit signatures (for D$_f$=2), but with different particle size distributions. Finally, we conclude that the simulated haze particles should have major implications for the atmospheric thermal structure and for the properties of condensation clouds.
