Abstract
We present a new algorithm to estimate quasar photometric redshifts (photo-zs), by considering the asymmetries in the relative flux distributions of quasars. The relative flux models are built with multivariate Skew-t distributions in the multidimensional space of relative fluxes as a function of redshift and magnitude. For 151,392 quasars in the SDSS, we achieve a photo-z accuracy, defined as the fraction of quasars with the difference between the photo-z z

p
and the spectroscopic redshift z

s
,

within 0.1, of 74%. Combining the WISE W1 and W2 infrared data with the SDSS data, the photo-z accuracy is enhanced to 87%. Using the Pan-STARRS1 or DECaLS photometry with WISE W1 and W2 data, the photo-z accuracies are 79% and 72%, respectively. The prior probabilities as a function of magnitude for quasars, stars, and galaxies are calculated, respectively, based on (1) the quasar luminosity function, (2) the Milky Way synthetic simulation with the Besançon model, and (3) the Bayesian Galaxy Photometric Redshift estimation. The relative fluxes of stars are obtained with the Padova isochrones, and the relative fluxes of galaxies are modeled through galaxy templates. We test our classification method to select quasars using the DECaLS g, r, z, and WISE W1 and W2 photometry. The quasar selection completeness is higher than 70% for a wide redshift range

, and a wide magnitude range

mag. Our photo-z regression and classification method has the potential to extend to future surveys. The photo-z code will be publicly available.
The Structure of Titan’s N2 and CH4 Coronae
Authors: Jiang Fayu , Cui Jun , Xu Jiyao 
Published: December 2017

Abstract
In this study, we analyze the structures of Titan’s N2 and CH4 coronae using a large data set acquired by the Ion Neutral Mass Spectrometer (INMS) instrument on board Cassini. The N2 and CH4 densities measured from the exobase up to 2000 km imply a mean exobase temperature of 146 K and 143 K, respectively, which is lower than the mean upper atmospheric temperature by 4 and 7 K. This indicates that on average, Titan possesses a subthermal rather than suprathermal corona. A careful examination reveals that the variability in corona structure is not very likely to be solar driven. Within the framework of the collisionless kinetic model, we investigate how the CH4 energy distribution near the exobase could be constrained if strong CH4 escape occurs on Titan. Several functional forms for the CH4 energy distribution are attempted, assuming two representative CH4 escape rates of

s−1 and

s−1. We find that the double Maxwellian and power-law distributions can reproduce the shape of the CH4 corona structure as well as the imposed CH4 escape rate. In both cases, the escape rate is contributed by a suprathermal CH4 population on the high-energy tail, with a number fraction below 5% and a characteristic energy of 0.1–0.6 eV per suprathermal CH4 molecule. The coexistence of the subthermal CH4 corona revealed by the INMS data and substantial CH4 escape suggested by some previous works could be reconciled by a significant departure in the exobase CH4 energy distribution from ideal Maxwellian that enhances escape and causes a noticeable redistribution of the corona structure.
Hot Molecular Gas in the Circumnuclear Disk
Authors: Mills Elisabeth A. C. , Togi Aditya , Kaufman Michael 
Published: December 2017

Abstract
We present an analysis of archival Infrared Space Observatory observations of H2 for three

pointings in the central 3 pc of the Galaxy: toward the southwest region and northeast region of the Galactic center circumnuclear disk (CND), and toward the supermassive black hole Sgr A*. We detect pure rotational lines from 0–0 S(0) to S(13), as well as a number of rovibrationally excited transitions. Using the pure rotational lines, we perform both fits to a discrete temperature distribution (measuring up to three temperature components with T = 500–600 K, T = 1250–1350 K, and T > 2600 K) and fits to a continuous temperature distribution, assuming a power-law distribution of temperatures. We measure power-law indices of n = 3.22 for the northeast region and n = 2.83 for the southwest region. These indices are lower than those measured for other galaxies or other Galactic center clouds, indicating a larger fraction of gas at high temperatures. We also test whether extrapolating this temperature distribution can yield a reasonable estimate of the total molecular mass, as has been recently done for H2 observations in other galaxies. Extrapolating to a cutoff temperature of 50 K in the southwest (northeast) region, we would measure 32% (140%) of the total molecular gas mass inferred from the dust emission, and 26% (125%) of the total molecular gas mass inferred from the CO emission. Ultimately, the inconsistency of the masses inferred in this way suggests that a simple application of this method cannot yield a reliable estimate of the mass of the CND.
A Monster CME Obscuring a Demon Star Flare
Authors: Moschou Sofia-Paraskevi , Drake Jeremy J. , Cohen Ofer , Alvarado-Gomez Julian D. , Garraffo Cecilia 
Published: December 2017

Abstract
We explore the scenario of a coronal mass ejection (CME) being the cause of the observed continuous X-ray absorption of the 1997 August 30 superflare on the eclipsing binary Algol (the Demon Star). The temporal decay of the absorption is consistent with absorption by a CME undergoing self-similar evolution with uniform expansion velocity. We investigate the kinematic and energetic properties of the CME using the ice cream cone model for its three-dimensional structure in combination with the observed profile of the hydrogen column density decline with time. Different physically justified length scales were used that allowed us to estimate lower and upper limits of the possible CME characteristics. Further consideration of the maximum available magnetic energy in starspots leads us to quantify its mass as likely lying in the range

g and kinetic energy in the range

erg. The results are in reasonable agreement with extrapolated relations between flare X-ray fluence and CME mass and kinetic energy derived for solar CMEs.
The Hawaii SCUBA-2 Lensing Cluster Survey: Are Low-luminosity Submillimeter Galaxies Detected in the Rest-frame UV?

Published: December 2017

Abstract
In this third paper of the Hawaii SCUBA-2 Lensing Cluster Survey series, we present Submillimeter Array (SMA) detections of six intrinsically faint 850 μm sources detected in SCUBA-2 images of the lensing cluster fields, A1689, A2390, A370, MACS J0717.5+3745, and MACS J1423.8+2404. Two of the SCUBA-2 sources split into doublets, yielding a total of eight SMA detections. The intrinsic 870 μm flux densities of these submillimeter galaxies (SMGs) are ∼1 mJy. Five of the eight SMGs are not detected in optical or near-infrared (NIR) images. The NIR-to-submillimeter flux ratios of these faint SMGs suggest that most of them are extremely dusty and/or are at very high redshifts. By combining these SMGs and several other samples from the literature, we find a bimodal distribution for the faint sources in the space of submillimeter flux versus NIR-to-submillimeter flux ratio. While most of the SMA-detected lensed sources are very obscured, the other SMGs with similar flux densities are mostly bright in the NIR. Future Atacama Large Millimeter/submillimeter Array observations of a large sample of SCUBA-2 sources in cluster fields will allow us to decide whether or not the bimodality we observe here really exists.
Deep K-band Observations of TMC-1 with the Green Bank Telescope: Detection of HC7O, Nondetection of HC11N, and a Search for New Organic Molecules
Authors: Cordiner M. A. , Charnley S. B. , Kisiel Z. , McGuire B. A. , Kuan Y.-J. 
Published: December 2017

Abstract
The 100 m Robert C. Byrd Green Bank Telescope K-band (KFPA) receiver was used to perform a high-sensitivity search for rotational emission lines from complex organic molecules in the cold interstellar medium toward TMC-1 (cyanopolyyne peak), focussing on the identification of new carbon-chain-bearing species as well as molecules of possible prebiotic relevance. We report a detection of the carbon-chain oxide species HC7O and derive a column density of

cm−2. This species is theorized to form as a result of associative electron detachment reactions between oxygen atoms and C7H−, and/or reaction of C6H2
+ with CO (followed by dissociative electron recombination). Upper limits are given for the related HC6O, C6O, and C7O molecules. In addition, we obtained the first detections of emission from individual 13C isotopologues of HC7N, and derive abundance ratios HC7N/HCCC13CCCCN = 110 ± 16 and HC7N/HCCCC13CCCN = 96 ± 11, indicative of significant 13C depletion in this species relative to the local interstellar elemental 12C/13C ratio of 60–70. The observed spectral region covered two transitions of HC11N, but emission from this species was not detected, and the corresponding column density upper limit is

(at 95% confidence). This is significantly lower than the value of

previously claimed by Bell et al. and confirms the recent nondetection of HC11N in TMC-1 by Loomis et al. Upper limits were also obtained for the column densities of malononitrile and the nitrogen heterocycles quinoline, isoquinoline, and pyrimidine.
An Evaluation of Cosmological Models from the Expansion and Growth of Structure Measurements
Authors: Zhai Zhongxu , Blanton Michael , Slosar Anže , Tinker Jeremy 
Published: December 2017

Abstract
We compare a large suite of theoretical cosmological models to observational data from the cosmic microwave background, baryon acoustic oscillation measurements of expansion, Type Ia supernova measurements of expansion, redshift space distortion measurements of the growth of structure, and the local Hubble constant. Our theoretical models include parametrizations of dark energy as well as physical models of dark energy and modified gravity. We determine the constraints on the model parameters, incorporating the redshift space distortion data directly in the analysis. To determine whether models can be ruled out, we evaluate the p-value (the probability under the model of obtaining data as bad or worse than the observed data). In our comparison, we find the well-known tension of H
0 with the other data; no model resolves this tension successfully. Among the models we consider, the large-scale growth of structure data does not affect the modified gravity models as a category particularly differently from dark energy models; it matters for some modified gravity models but not others, and the same is true for dark energy models. We compute predicted observables for each model under current observational constraints, and identify models for which future observational constraints will be particularly informative.
Incorrect emotions in ancient, austrian & contemporary philosophy
Authors: Mulligan Kevin 
Published: December 2017

Après avoir présenté les conceptions antiques de l’órexis, on soulève quelques questions sur la nature de la « correction non intellectuelle », tout en examinant les réponses offertes par Brentano et ses héritiers, ainsi que celles que propose la philo¬sophie contemporaine des valeurs et de l’esprit. On propose de comprendre la conception brentanienne des valeurs en termes d’orthonomie : x a une valeur si une émotion ou un désir positifs de x est correct (et cette émotion ou ce désir sont connaissables). Mais certains textes de Brentano décrivent aussi la correction en termes relationnels (une relation entre un acte mental et une forme déontique), ce qui va dans le sens des théories contemporaines du buck-passing et de la fitting attitude. Brentano penche ainsi souvent pour une conception non relationnelle de la correction, mais opte aussi parfois pour une conception relationnelle.

Authors: Priyadarshini Reddy , Kumar Yasangi M , Priya K Shanthi , LNU Chunchuvyshnavi , Yerrapragada Harika 
Published: December 2017

ABSTRACT

Aim
The aim of this study is to evaluate the effect of temperature change on film thickness of both types of cements.

Materials and methods
Totally, 60 samples were prepared with 10 in each subgroup, thus comprising 30 in each group. Materials tested were glass ionomer cement (GIC) type I and zinc phosphate type I. Samples were manipulated with manufacturer's instructions and tested according to American Dental Association (ADA) guidelines.

Results
The mean values of film thickness were recorded for both groups I and II. In intragroup comparison of group 1, subgroup III (26.560 ± 0.489 µm) was found to have the highest film thickness followed by subgroup II (24.182 ± 0.576 µm) and the lowest in subgroup I (20.209 ± 0.493 µm). In intragroup comparison of group II, the film thickness recorded in subgroup III (25.215 ± 0.661 µm) was the highest followed by subgroup II (21.471 ± 0.771 µm) and the least in subgroup I (17.951 ± 0.654 µm; p < 0.01). In intergroup comparison of groups I and II, group II (21.545 ± 0.841) was found to have less film thickness than group I (23.650 ± 0.271). The results were found to be statistically significant (p < 0.01).

Conclusion
Both zinc phosphate and GICs can be used satisfactorily for luting purpose. The temperature fluctuations have a direct influence on the film thickness. Zinc phosphate has less film thickness than GIC.

Clinical significance
Zinc phosphate should be preferred over GIC in clinical practice, and more stress should be given in mechanical preparation of crowns for better retentive quality of prosthesis.

Spanning the Horizon of Accuracy of Different Intraoral Radiographic Modalities: A Systematic Review
Authors: Muchhal Mohnish , Niraj Lav K , Chaudhary Devanshu , Ali Irfan , Dhama Kuldeep , Patthi Basavaraj 
Published: December 2017

ABSTRACT

Aim
This study was conducted with an aim to systematically review the literature for assessing the accuracy of intraoral radiographs in detection of dental caries.

Introduction
Despite the advancements in oral disease science, dental caries continues to be a worldwide health concern, affecting humans of all ages. Correct diagnosis of caries is critical both in clinical practice as well as in epidemiology and radiography are worthwhile adjunct for a thorough examination.

Results
A literature review was performed in PubMed Central and Cochrane library, Embase, and Google Scholar, and these databases were searched up to 2016. The primary outcome measure was to assess the accuracy of intraoral radiographs in the detection of dental caries based on sensitivity and specificity. The sensitivity for conventional radiographs for the detection of lesions in enamel (16–68%) and dentin (16–96%) was found to be superior as compared with other modalities of digital radiography, whereas the specificity of digital radiography was found to be superior in detection of lesion in enamel (77–96%) and dentin (84–100%) when compared with conventional radiography. Sensitivity of conventional radiographs was noted to be superior as compared with digital radiography, whereas in terms of specificity, digital was found to be superior to conventional radiographs.

Conclusion
Although there was no significant difference between digital and conventional radiography in the diagnosis of caries, conventional radiographs were able to detect carious lesion, in general, but for lesion to be detected precisely, digital was found to be superior.

Clinical significance
As digital radiography produces lower ionizing radiation, dental professionals should employ this method in their routine dental practice for diagnosing and treating carious lesions.

RESUMEN

Introducción
La ventana pericárdica es el estándar de oro en el diagnóstico de trauma cardiaco en heridas precordiales estando descritas diferentes vías de abordaje. El objetivo de este estudio es comparar las características clínicas, desenlaces y rendimiento diagnóstico de las vías subxifoidea vs. toracoscópica en pacientes con trauma precordial abierto.

Diseño del Estudio
Estudio observacional de cohortes, en un periodo de 56 meses, se recopilaron pacientes con heridas penetrantes en región precordial, hemodinámicamente estables que ingresaron al Servicio de Urgencias, a quienes se indicó la realización de ventana pericárdica para descartar lesiones cardiacas. Se compararon las características clínicas, desenlaces y el rendimiento diagnóstico de las pruebas.

Resultados
Se incluyeron 256 pacientes, 93.4% ingresaron por herida por arma cortopunzante, 18.8% de las ventanas pericárdicas fueron vía toracoscópica, 20.8% resultaron positivas para hemopericardio y 11.5% de las subxifoideas, la mediana de la estancia hospitalaria fue 4 días, 16.0% presentaron complicaciones, 17.8% en pacientes abordados por vía subxifoidea y 8.3% vía toracoscópica siendo más frecuente el hemotórax coagulado, 15.2% fueron llevados a reintervención, la mayoría a toracoscopia para drenaje de hemotórax coagulado (62.5%), la mortalidad fue 1.6%, todos los casos en el grupo del abordaje subxifoideo. La sensibilidad de la ventana pericárdica subxifoidea fue 95.8% y la toracoscópica 90.9%, y la especificidad fue 99.5% y 100%, respectivamente.

Conclusión
El abordaje toracoscópico es una opción diagnóstica con rendimiento similar al subxifoideo. A pesar de establecer una disminución en la mediana de los días como usuarios de sonda de toracostomía, no se observó disminución en los días de estancia hospitalaria.

Red Wave: Improving Care to Severe Trauma Victims
Authors: Romeo Ana C , Cunha Andre G , Filho Pedro S , Oliveira Victor , Moura Thiago , Motta Jorge , Mendes Gustavo , Cruz Marcio R 
Published: December 2017

ABSTRACT
Objectives
To describe the results of a systematic, rapid, and effective method of communication for the definitive treatment of patients with severe traumatic bleeding.

Materials and methods
The Red Wave was developed to improve communication between the emergency department and other strategical processes and to reduce the time from the arrival of severe traumatic hemorrhagic patient to a definitive treatment in the operating room.
On admission, the traumatized patient is seen by the nursing staff in the Red Room, who trigger a general bell indicating the arrival of a severe trauma patient.
The surgeon activates the red bell, which triggers an audible and visual alarm at strategic sectors of the hospital: operating center, transfusional agency, and laboratory, each one with its established sub-protocol. We defined as goals that the patient must arrive at the operating room in a maximum of 15 minutes after the Red Wave activation, with availability of blood and plasma in 20 minutes and blood tests collected at the same time. A light panel located in the surgical center turns off at each completed step, recording their time-responses.

Results
From June through December 2015, we admitted 831 trauma patients in the Red Room of Hospital do Suburbio, predominantly young (67.9% younger than 40 years old) and male (77.5%). Blunt trauma was the predominant mechanism (79.2%), and the majority of patients had an revised trauma score (RTS) calculated at admission greater than 7 (86.5%).
We also evaluated, from September through December 2015, the attendance of 96 patients admitted with a diagnosis of hemorrhagic traumatic shock. The Red Wave was triggered in 39.6% of these cases. Gunshot wounds were the most frequent mechanism of trauma (86.5%), with a survival rate of 56.8%.
The goals for time-responses were met in most of the cases, with correctness of 81.6% for the patient arrival at the operating room, 81.6% for laboratory sampling, and 86.8% for blood and plasma availability by the transfusion agency.

Conclusion
The Red Wave proved to be an effective protocol to systematize the initial treatment of patients with severe traumatic bleeding, improving communication between the strategic sectors involved, reducing the time-response of each service and making the definitive treatment of these patients faster and suitable.
