Metal Abundances of KISS Galaxies. VI. New Metallicity Relations for the KISS Sample of Star-forming Galaxies
Authors: Hirschauer Alec S. , Salzer John J. , Janowiecki Steven , Wegner Gary A. 
Published: January 2018

Abstract
We present updated metallicity relations for the spectral database of star-forming galaxies (SFGs) found in the KPNO International Spectroscopic Survey (KISS). New spectral observations of emission-line galaxies obtained from a variety of telescope facilities provide oxygen abundance information. A nearly fourfold increase in the number of KISS objects with robust metallicities relative to our previous analysis provides for an empirical abundance calibration to compute self-consistent metallicity estimates for all SFGs in the sample with adequate spectral data. In addition, a sophisticated spectral energy distribution fitting routine has provided robust calculations of stellar mass. With these new and/or improved galaxy characteristics, we have developed luminosity–metallicity (L–Z) relations, mass–metallicity (M
*–Z) relations, and the so-called fundamental metallicity relation (FMR) for over 1450 galaxies from the KISS sample. This KISS M
*–Z relation is presented for the first time and demonstrates markedly lower scatter than the KISS L–Z relation. We find that our relations agree reasonably well with previous publications, modulo modest offsets due to differences in the strong emission line metallicity calibrations used. We illustrate an important bias present in previous L–Z and M
*–Z studies involving direct-method (T

e
) abundances that may result in systematically lower slopes in these relations. Our KISS FMR shows consistency with those found in the literature, albeit with a larger scatter. This is likely a consequence of the KISS sample being biased toward galaxies with high levels of activity.

Abstract
We present 2MASS J11151597+1937266, a recently identified low-surface-gravity L dwarf, classified as an L2γ based on Sloan Digital Sky Survey optical spectroscopy. We confirm this spectral type with near-infrared spectroscopy, which provides further evidence that 2MASS J11151597+1937266 is a low-surface-gravity L dwarf. This object also shows significant excess mid-infrared flux, indicative of circumstellar material; and its strong Hα emission (EWHα
= 560 ± 82 Å) is an indicator of enhanced magnetic activity or weak accretion. Comparison of its spectral energy distribution to model photospheres yields an effective temperature of

. We also provide a revised distance estimate of 37 ± 6 pc using a spectral type–luminosity relationship for low-surface-gravity objects. The three-dimensional galactic velocities and positions of 2MASS J11151597+1937266 do not match any known young association or moving group. Assuming a probable age in the range of 5–45 Myr, the model-dependent estimated mass of this object is between 7 and 21 M
Jup, making it a potentially isolated planetary-mass object. We also identify a candidate co-moving, young stellar companion, 2MASS J11131089+2110086.
The Physics of Protoplanetary Dust Agglomerates. X. High-velocity Collisions between Small and Large Dust Agglomerates as a Growth Barrier
Authors: Schräpler Rainer , Blum Jürgen , Krijt Sebastiaan , Raabe Jan-Hendrik 
Published: January 2018

Abstract
In a protoplanetary disk, dust aggregates in the μm to mm size range possess mean collision velocities of 10–60 m s−1 with respect to dm- to m-sized bodies. We performed laboratory collision experiments to explore this parameter regime and found a size- and velocity-dependent threshold between erosion and growth. By using a local Monte Carlo coagulation calculation and along with a simple semi-analytical timescale approach, we show that erosion considerably limits particle growth in protoplanetary disks and leads to a steady-state dust-size distribution from μm- to dm-sized particles.
Extreme Value Theory Applied to the Millennial Sunspot Number Series
Authors: Acero F. J. , Gallego M. C. , García J. A. , Usoskin I. G. , Vaquero J. M. 
Published: January 2018

Abstract
In this work, we use two decadal sunspot number series reconstructed from cosmogenic radionuclide data (14C in tree trunks, SN 14C, and 10Be in polar ice, SN 10Be) and the extreme value theory to study variability of solar activity during the last nine millennia. The peaks-over-threshold technique was used to compute, in particular, the shape parameter of the generalized Pareto distribution for different thresholds. Its negative value implies an upper bound of the extreme SN 10Be and SN 14C timeseries. The return level for 1000 and 10,000 years were estimated leading to values lower than the maximum observed values, expected for the 1000 year, but not for the 10,000 year return levels, for both series. A comparison of these results with those obtained using the observed sunspot numbers from telescopic observations during the last four centuries suggests that the main characteristics of solar activity have already been recorded in the telescopic period (from 1610 to nowadays) which covers the full range of solar variability from a Grand minimum to a Grand maximum.
Du paysage au bien-être : la puissance d’agir des habitants. Le cas des grands projets d’équipement (et de leurs concertations officielles)
Authors: Faburel Guillaume 
Published: January 2018

Le désir de bien-être caractériserait ce jour une demande sociale croissante. Ce désir est toutefois fréquemment compris comme le produit d’une sensation personnelle ou d’un sentiment individuel, particulièrement lorsque des habitants l’invoquent à l’occasion des concertations officielles accompagnant tout grand projet d’équipement. Une enquête par entretien ouvert et par groupe de discussion a été menée dans trois communes périurbaines ou rurales, directement concernées en 2011 et 2012 par deux projets de Lignes à Grande Vitesse. Il en ressort que le bien-être est d’abord un véhicule de communs territorialisés, dans lesquels les expériences paysagères et les valeurs dont elles seraient porteuses jouent un rôle premier, au point, dès lors, d’augmenter la puissance d’agir des habitants… par les affects. Nous ouvrons alors le débat sur la construction plus dialogique des savoirs et outils paysagers, et notamment les cartographies proposées par les porteurs de projets et leurs maîtrises d’ouvrage.

Published: January 2018

Abstract
OBJECTIVE. The objective of this article was to explore the effects of enhanced lighting on the function of people with an acquired visual deficit resulting from cerebrovascular accident (CVA) in an inpatient rehabilitation facility (IRF).
METHOD. An ABAB design was used with two cases to assess how a short-term intervention involving lighting changes affected clients’ grooming performance in an IRF. Analysis consisted of scores on the grooming section of the FIM®, times for each grooming task, and light meter readings.
RESULTS. Both participants demonstrated improvements in function as measured by the FIM and in time to complete grooming tasks with enhanced lighting.
CONCLUSION. These results suggest that individualized lighting can lead to improved grooming function in clients with CVA.

Published: January 2018

Abstract
OBJECTIVE. We evaluated the impact of a 1-wk activity program on the health, quality of life (QOL), and occupational performance of community-living women diagnosed with cancer.
METHOD. A one-group pretest–posttest repeated-measures design was used. Participants completed a functional health measure (36-Item Short Form Health Survey [SF–36]), a QOL measure (World Health Organization Quality of Life–Brief version [WHOQOL–BREF]), and an occupational performance and satisfaction measure (Canadian Occupational Performance Measure [COPM]) before and 6 wk after program completion. The COPM was also administered on Day 5.
RESULTS. Paired t tests for the SF–36 and WHOQOL–BREF showed no significant differences, except for the WHOQOL–BREF’s Social Relationships subscale (p &lt; .008). Repeated-measures analyses of variance showed a significant difference in COPM performance and satisfaction scores (p &lt; .001).
CONCLUSION. The activity program effectively improved occupational performance and satisfaction and social relationships of community-living women diagnosed with cancer.

AbstractOBJECTIVE. The overall aim of this study is to create an item pool reflecting the cognitive concerns expressed by people with HIV as a first step toward developing such a measure.METHOD. Semiqualitative interviews with 292 people with HIV were carried out. Their concerns were mapped to neurocognitive domains to identify concern content areas and were compared with existing cognitive questionnaires. A questionnaire was developed to estimate the prevalence and importance of the items.RESULTS. Sixty of 125 items were retained in the questionnaire based on ratings of their prevalence, importance, and clarity. Memory and behavioral and emotional concerns were the most common content areas (15 each); other domains were attention (7), executive function (6), language (5), and cognitive change (12).CONCLUSION. People living with HIV experience difficulties in all domains of cognition. By recognizing all domains, this new measure can help clinicians better understand areas of perceived cognitive difficulty and plan interventions accordingly.

Published: January 2018

In this study, the potential of dry reforming reaction over CaFe2O4 supported Ni and Co catalysts were investigated. The Co/CaFe2O4 and Ni/CaFe2O4 catalysts were synthesized using wet impregnation method by varying the metal loading from 5-15 %. The synthesized catalysts were tested in methane dry reforming reaction at atmospheric pressure and reaction temperature ranged 700-800 oC. The catalytic performance of the catalysts based on the initial screening is ranked as 5%Co/CaFe2O4 < 10%Co/CaFe2O4 < 5%Ni/CaFe2O4 < 10%Ni/CaFe2O4 according to their performance. The Ni/CaFe2O4 catalyst was selected for further investigation using full factorial design of experiment. The interaction effects of three factors namely metal loading (5-15 %), feed ratio (0.4-1.0), and reaction temperature (700-800 oC) were evaluated on the catalytic activity in terms of CH4 and CO2 conversion as well as H2 and CO yield. The interaction between the factors showed significant effects on the catalyst performance at metal loading, feed ratio and reaction temperature of 15 %, 1.0, and 800 oC. respectively. The 15 wt% Ni/CaFe2O4 was subsequently characterized by Thermogravimetric (TGA), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDX), X-ray Photoelectron Spectroscopy (XPS), N2-physisorption, Temperature Programmed Desorption (TPD)-NH3, TPD-CO2, and Fourier Transform Infra Red (FTIR) to ascertain its physiochemical properties. This study demonstrated that the CaFe2O4 supported Ni catalyst has a good potential to be used for syngas production via methane dry reforming.
Synthesis, Structure, and Catalytic Activity of A New Mn(II) Complex with 1,4-Phenylenediacetic Acid and 1,10-Phenanthroline
Authors: Wang Li Hua , Li Peng Fei 
Published: January 2018

A new Mn(II) complex material has been synthesized by one-pot reaction of Mn(CH3COO)2·4H2O, 1,4-phenylenediacetic (H2L), 1,10-phenanthroline (phen), and NaOH in water/ethanol (v:v = 1:1) solution. The structure of Mn(II) complex was determined by elemental analysis, FTIR, and X-ray single-crystal diffraction analysis. The results reveal that Mn(II) complex was constructed by a monodentate 1,4-phenylenediacetate ligand, two phen ligands, a coordinated water molecule, 0.5 uncoordinated 1,4-phenylenediacetate ligand and six uncoordinated water molecules. The complex molecules form 1D chain structure by the π-π interaction of phen molecules. The catalytic activity of Mn(II) complex for coupling of benzaldehyde, phenylacetylene and piperidine in 1,4-dioxane has also been investigated and the maximum yield of propargylamine is up to 72.2 % after 12 h at 120 oC.

Published: January 2018

Tropomyosins, a family of actin‐associated proteins, bestow actin filaments with distinct biochemical and physical properties which are important for determining cell shape and regulating many cellular processes in eukaryotic cells. Here, we used RNA‐seq to investigate the effect of four tropomyosin isoforms on gene expression in undifferentiated and differentiated rat B35 neuroblastoma cells. In undifferentiated cells, overexpression of tropomyosin isoforms Tpm1.12, Tpm2.1, Tpm3.1, and Tpm4.2 differentially regulates a vast number of genes, clustering into several gene ontology terms. In differentiated cells, tropomyosin overexpression exerts a much weaker influence on overall gene expression. Our findings are particularly compelling because they demonstrate that tropomyosin‐dependent changes are attenuated once the cells are induced to follow a defined path of differentiation.DatabaseSequence data for public availability are deposited in the European Nucleotide Archive under the accession number PRJEB24136.

Published: January 2018

l‐Amino acid oxidase/monooxygenase from Pseudomonas sp. AIU 813 (l‐AAO/MOG) catalyzes both the oxidative deamination and oxidative decarboxylation of the α‐group of l‐Lys to produce a keto acid and amide, respectively. l‐AAO/MOG exhibits limited specificity for l‐amino acid substrates with a basic side chain. We previously determined its ligand‐free crystal structure and identified a key residue for maintaining the dual activities. Here, we determined the structures of l‐AAO/MOG complexed with l‐Lys, l‐ornithine, and l‐Arg and revealed its substrate recognition. Asp238 is located at the ceiling of a long hydrophobic pocket and forms a strong interaction with the terminal, positively charged group of the substrates. A mutational analysis on the D238A mutant indicated that the interaction is critical for substrate binding but not for catalytic control between the oxidase/monooxygenase activities. The catalytic activities of the D238E mutant unexpectedly increased, while the D238F mutant exhibited altered substrate specificity to long hydrophobic substrates. In the ligand‐free structure, there are two channels connecting the active site and solvent, and a short region located at the dimer interface is disordered. In the l‐Lys complex structure, a loop region is displaced to plug the channels. Moreover, the disordered region in the ligand‐free structure forms a short helix in the substrate complex structures and creates the second binding site for the substrate. It is assumed that the amino acid substrate enters the active site of l‐AAO/MOG through this route.DatabaseThe atomic coordinates and structure factors (codes 5YB6, 5YB7, and 5YB8) have been deposited in the Protein Data Bank (http://wwpdb.org/).EC numbers1.4.3.2 (l‐amino acid oxidase), 1.13.12.2 (lysine 2‐monooxygenase).
Organic–Inorganic Hybrid Hollow Nanoparticles Suppress Oxidative Stress and Repair Damaged Tissues for Treatment of Hepatic Fibrosis

Published: January 2018

AbstractCurrent therapeutic options for the treatment of liver fibrosis are limited, and transplantation is often the only effective option for end‐stage fibrotic diseases. To overcome this problem, a nanoparticle‐based treatment as an alternative to transplantation is developed. Multifunctional organic–inorganic hybrid hollow nanoparticles (HNPs) containing silibinin are synthesized by mixing precursors in ammonia water at 60 °C for 1 min. The HNPs are mainly composed of siloxanes and disulfides and have surface thiols. The disulfides are cleaved by intracellular glutathione and reduced to thiols, leading to the deformation of the HNPs. Silibinin molecules are released through the cracks formed by HNP deformation. Furthermore, the HNPs suppress the generation of hydroxyl radicals, a major cause of liver fibrosis, via sulfenylation reactions of HNP thiols. Retinol‐modified HNPs target Kupffer cells and hepatic stellate cells, which are essential for hepatic fibrogenesis. The combined suppression of hydroxyl radical generation and release of silibinin using the HNPs decreases the proportion of fibrotic tissues and improves hepatic function. The therapeutic efficacy is greater than can be achieved by the suppression of hydroxyl radical generation alone and the injection of silibinin alone. Thus, HNPs are promising for the treatment of liver fibrosis.

AbstractSculpturing desired shapes in single crystal diamond is ever more crucial in the realization of complex devices for nanophotonics, quantum computing, and quantum optics. The crystallographic orientation dependent wet etch of single crystalline silicon in potassium hydroxide (KOH) allows a range of shapes to be formed and has significant impacts on microelectromechanical systems (MEMS), atomic force microscopy (AFM), and microfluidics. Here, a crystal direction dependent dry etching principle in an inductively coupled plasma reactive ion etcher is presented, which selectively reveals desired crystal planes in monocrystalline diamond by controlling the etching conditions. Using this principle, monolithic diamond nanopillars for magnetometry using nitrogen vacancy centers are fabricated. In these nanopillars, a half‐tapering angle up to 21° is achieved, the highest angle reported in the literature, which leads to a high photon efficiency and high mechanical strength of the nanopillar. These results represent the first demonstration of a crystallographic orientation dependent reactive ion etching principle, which opens a new window for shaping specific nanostructures which is at the heart of nanotechnology. It is believed that this principle will prove to be valuable for the structuring and patterning of other single crystal materials as well.
Rational Design of Fe1−xS/Fe3O4/Nitrogen and Sulfur‐Doped Porous Carbon with Enhanced Oxygen Reduction Reaction Catalytic Activity

Published: January 2018

AbstractIn this paper, the rational design of Fe‐N‐, Fe‐S‐, and Fe‐N‐S‐based model catalysts for oxygen reduction reaction (ORR), developed using task‐specific hypercrosslinked polymers as precursors is presented. Based on the model catalysts, atom‐induced differences in ORR performance are carefully examined. In the S‐doped carbons, Fe1−xS forms the metal nanoparticles, while the N sourced together with FeCl3 ensures the uniform distribution of Fe3O4. Obtained results indicate that N/Fe3O4 acts as the higher catalytic active site, whereas the S/Fe1−xS deteriorates the ORR catalytic activity. However, due to the synergistic effect between Fe1−xS /Fe3O4 and N, the S‐doped carbons can substantially enhance the ORR performance. Hence, this work provides guidance for the efficient design of Fe‐N‐S‐based catalysts for ORR.

Published: January 2018

AbstractSelf‐organization of chiral superstructures in liquid crystal (LC) materials is a powerful tool in developing functional devices based on soft matter. The control and manipulation of the helical axis orientation in chiral nematic liquid crystals are currently attracting significant attention, but are hindered by limited control over the anchoring at the interfaces. The development of new alignment techniques with local control over polar and azimuthal anchoring can open up a wide range of possibilities. Here a new photoalignment process based on a mixture of photosensitive azo compounds and homeotropic alignment materials is developed and demonstrated. The alignment of the LC director near the surface depends on both intensity and polarization of the UV illumination. By two‐beam interference UV illumination, periodic stripes of planar and homeotropic anchoring are realized. In addition it is demonstrated that the stripes of planar and homeotropic anchoring stabilize and align cholesteric fingers in cells with thickness smaller than the pitch. The 2D director configuration in the cholesteric fingers is identified by matching the experimental observations with numerical simulations based on finite element Q‐tensor calculations.

AbstractObjectiveThe purpose a methodology that excludes values outside of the expected spectrum for age (VOESA) of height and body mass in the definition of power (p) to construct an international allometric body mass index (AI) for children and adolescents.MethodsDatasets of national surveys including individuals (aged 0–19 years) from five countries (Brazil, South Korea, Mexico, England, and the USA) were selected. The p was defined for each country, age range, and sex after exclusion of VOESA for height and weight by log–log linear regression, where β represented p. The p was also defined for a pool of five countries, international p (ip) after exclusion of VOESA using a spline modeling technique (5 knots). The AI was calculated and Pearson's correlation coefficient (r) was calculated to investigate the correlation between AI and height.ResultsExclusion of VOESA decreased the difference of p among countries. Exponent p showed values close to 2 in the first years of life, increased to 3–3.5 between 7 and 11 years for girls and 8 to 12 years for boys, and decreased to close to 2 near the end of growth (16 years for girls and 19 years for boys). The use of ip for all countries decreased r values to near zero while BMI had values near 0.4.ConclusionsExclusion of VOESA contributes to a decreased effect of epidemiological context among countries when calculating the AI. AI calculated using ip is independent of height in all countries and reflects physiological growth changes for children and adolescents.
