Cloud-Computing Risk Disclosure and ICFR Material Weakness: The Moderating Role of Accounting Reporting Complexity
Authors: Smith Antoinette L. , Zhang Yibo (James) , Kipp Peter C. 
Published: April 2018

ABSTRACT
Regulators have expressed concerns over management's ability to maintain effective ICFR when adopting cloud-computing services (PCAOB 2015), as well as the auditor's ability to cope with such changes (PCAOB 2015, 2017). Further, the complexity of the client's accounting concepts, proxied by their XBRL taxonomy, could adversely impact financial reporting quality. We investigate the association between a firm's disclosure of cloud-computing risks and its likelihood of disclosing a material weakness, moderated by its level of accounting reporting complexity. We find that, for firms that identify cloud-computing as a significant risk, the external auditor is less likely to issue a material weakness when the firm uses a greater number of customized XBRL tags. We also find that the external auditor is more likely to issue a material weakness for firms that do not identify cloud-computing as a significant risk to their operations when they use a greater number of customized XBRL tags.

Active tectonics of Erçek Lake Basin and lithostratigraphy of basin deposits (Van, Turkey)
Authors: DOĞAN Bülent 
Published: April 2018

The Erçek Lake Basin
(ELB) is located in the eastern part of Van Lake and has an area of approximately
100 km2. The eastern section presents gully morphology towards
Özalp. Oligo-Miocene and Plio-Quaternary units cover the basement rocks of the
study area. Oligo-Miocene units are folded on both the southern and northern
parts of ELB. However, in the north of the basin, northward dipping thrust
faults generally developed along E-W. In the south, the fold axes differ by a
maximum of 30 ° from the E-W to the north. The distribution of the structural
elements within the Plio-Quaternary units is rather limited, and these are more
prominent in the north of the Erçek Lake. There are a few normal faults in
these structural elements. The development of these normal faults occurred as a
consequence of the N-S compression in the region and developed in the active
tectonic evolution of the region. The Kozluca left lateral strike-slip fault,
which also deforms the western margin of Lake Erçek and the intra-lake
morphology, is one of the other intra-plate structural elements within the
contracted continental crust.
Determination of Trace Amount of Lead in Industrial and Municipal Effluent Water Samples Based on Dispersive Liquid-Liquid Extraction
Authors: Shirkhanloo Hamid , Sedighi Kaveh , Zavvar Mousavi Hassan 
Published: April 2018

In this study, a simple, sensitive and accurate method was developed for the determination of lead ion by combining ionic liquid dispersive liquid-liquid extraction (IL-DLLE) with flame atomic absorption spectrometry. Tetraethylthiuram disulfide (TETD), acetone and 1-octyl-3-methylimidazolium hexafluorophosphate [(C8MIM) (PF6)] were used as the chelating agent, dispersive and extraction solvent, respectively. Under the optimal onditions, the calibration graph was linear in the range of 5-190 μg L-1 of lead and the detection limit was 0.8 μg L-1 with a sample volume of 200 mL. The proposed method was validated by the analysis of one certified reference material and applied successfully to the determination of lead in real water samples.
Electro-Fenton, UVA Photoelectro-Fenton and Solar Photoelectro-Fenton Treatments of Organics in Waters Using a Boron-Doped Diamond Anode: A Review
Authors: Brillas Enric 
Published: April 2018

The characteristics and applications of electrochemical advanced oxidation processes (EAOPs) like electro-Fenton (EF), UVA photoelectro-Fenton (PEF) and solar PEF (SPEF) with a boron-doped diamond (BDD) anode are reviewed. Their oxidative properties are based on the attack of •OH formed at the anode surface and in the medium from Fenton’s reaction between cathodically generated H2O2 and added Fe2+. The illumination with UVA light in PEF and sunlight in SPEF enhances the degradation process due to the photolysis of complexes of Fe(III) with generated carboxylic acids. Examples on the removal of industrial chemicals, pesticides, dyes and pharmaceuticals by these EAOPs using bench-scaled stirred tank reactors and pre-pilot plants are described. The influence of experimental variables on the mineralization and energetic parameters is detailed. The decay kinetics of pollutants and the evolution of intermediates are discussed. The SPEF process shows the best performance, being the most potent EAOP tested.

Published: April 2018

The effect of real dairy wastewater (DWW) additions on the current density generated by a bioanode was evaluated in a half cell configuration under potentiostatic control, thus simulating the anodic chamber of a Microbial Fuel Cell. Low substrate additions increased current density up to 1655 ± 136 mA m-2, forming a two-current peak pattern. Then the system was tested with a casein-lactose synthetic media. A high protein concentration reduced the current density; individual compounds led to the highest current (330.5 mA m-2 with casein; 1276 mA m-2 with lactose). Moreover, the protein reduced the current start up time.

Preparation of Ethyl Cellulose Nanoparticles by Solvent-Displacement Using the Conventional Method and a Recirculation System
Authors: Urbán-Morlán Zaida 
Published: April 2018

Ethyl cellulose polymeric nanoparticles (NPs) were prepared using the solvent-displacement technique with ethanol as the solvent. Optimization of the method included evaluating stirring rate and stabilizer type. NPs of 142.1 to 226.5 nm were obtained in a reproducible and efficient way (95% process efficiency) and with good stability (at room temperature). Moreover, a recirculation device was used in order to obtain concentrated NPs dispersions by a continuous process with potential scale-up. This method was challenged to encapsulate a hydrophilic antiviral model molecule (glycyrrhizinic acid) resulting in low entrapment efficiencies (approximately 1%). The results indicate that NPs are obtained using this simple, economical process that offers the possibility to transport different agents for applications in food-processing, cosmetics production or pharmaceutical products.

Predicting golf scores at the shot level
Authors: Drappi Christian , Co Ting Keh Lance 
Published: April 2018

We present the only model to date that predicts the discrete probability distribution of a golfer’s score for each hole of a tournament on a shot-by-shot basis. We first generalized Broadie’s technique of score-based skill estimation to allow a golfer’s skill (e.g. scoring average, driving spray, iron play, putting) to vary continuously by time-weighting data with exponential decay. Training a single-layer 50-node neural network to predict probabilities of scoring by hole resulted in an out-of-sample cross-entropy error of 0.974. We then added features of each hole (e.g. par, green size, sand area) onto the model, representing golfers and holes in an N-by-M dimensional space and achieved an error of 0.953. Adding in course features provided by ShotLink (e.g. fairway height, firmness, wind speed) dropped error to 0.9374. Finally, generalizing the model to update probabilities per shot further reduced error to 0.891. This work helps players understand which skill sets they should improve on, manage courses better (better to miss fairway right or left on hole 13 of Bethpage Black?) and select the best tournament to enter. It also revolutionizes the viewing experience of the PGA by live updating odds to win per shot (similar to WSOP) and helps sports books offer more accurate betting lines.
Model-independent Exoplanet Transit Spectroscopy
Authors: Aronson Erik , Piskunov Nikolai 
Published: April 2018

Abstract
We propose a new data analysis method for obtaining transmission spectra of exoplanet atmospheres and brightness variation across the stellar disk from transit observations. The new method is capable of recovering exoplanet atmosphere absorption spectra and stellar specific intensities without relying on theoretical models of stars and planets. We simultaneously fit both stellar specific intensity and planetary radius directly to transit light curves. This allows stellar models to be removed from the data analysis. Furthermore, we use a data quality weighted filtering technique to achieve an optimal trade-off between spectral resolution and reconstruction fidelity homogenizing the signal-to-noise ratio across the wavelength range. Such an approach is more efficient than conventional data binning onto a low-resolution wavelength grid. We demonstrate that our analysis is capable of reproducing results achieved by using an explicit quadratic limb-darkening equation and that the filtering technique helps eliminate spurious spectral features in regions with strong telluric absorption. The method is applied to the VLT FORS2 observations of the exoplanets GJ 1214 b and WASP-49 b, and our results are in agreement with previous studies. Comparisons between obtained stellar specific intensity and numerical models indicates that the method is capable of accurately reconstructing the specific intensity. The proposed method enables more robust characterization of exoplanetary atmospheres by separating derivation of planetary transmission and stellar specific intensity spectra (that is model-independent) from chemical and physical interpretation.
Tidal Deformability from GW170817 as a Direct Probe of the Neutron Star Radius
Authors: Raithel Carolyn A. , Özel Feryal , Psaltis Dimitrios 
Published: April 2018

Abstract
Gravitational waves from the coalescence of two neutron stars were recently detected for the first time by the LIGO–Virgo Collaboration, in event GW170817. This detection placed an upper limit on the effective tidal deformability of the two neutron stars and tightly constrained the chirp mass of the system. We report here on a new simplification that arises in the effective tidal deformability of the binary, when the chirp mass is specified. We find that, in this case, the effective tidal deformability of the binary is surprisingly independent of the component masses of the individual neutron stars, and instead depends primarily on the ratio of the chirp mass to the neutron star radius. Thus, a measurement of the effective tidal deformability can be used to directly measure the neutron star radius. We find that the upper limit on the effective tidal deformability from GW170817 implies that the radius cannot be larger than ∼13 km, at the 90% level, independent of the assumed masses for the component stars. The result can be applied generally, to probe the stellar radii in any neutron star–neutron star merger with a measured chirp mass. The approximate mass independence disappears for neutron star–black hole mergers. Finally, we discuss a Bayesian inference of the equation of state that uses the measured chirp mass and tidal deformability from GW170817 combined with nuclear and astrophysical priors and discuss possible statistical biases in this inference.
Tueurs, ibitero et notabilités génocidaires au Rwanda (Kigali, avril 1994)
Authors: Piton Florent 
Published: April 2018

À partir du rapport d’une organisation non gouvernementale rwandaise réalisé peu après la fin du génocide des Tutsi, cet article interroge la constitution et l’organisation des bandes de tueurs (ibitero). Il s’intéresse en particulier au massacre de la paroisse de Gikondo à Kigali le 9 avril 1994. Si les génocidaires viennent de toutes les catégories de la population, miroir en cela d’une « société ordinaire », il y a néanmoins des jeux de pouvoir au sein des bandes. Il existe des notabilités génocidaires qui ne reproduisent pas nécessairement les hiérarchies sociales et politiques antérieures : l’opportunisme politique, la conviction idéologique et l’inventivité meurtrière sont à la fois des motivations et des ressources mobilisées par les « tueurs de grand renom ».
Le mouvement transhumaniste
Authors: Damour Franck 
Published: April 2018

Le transhumanisme est un courant d’idées qui prône une transformation de l’être humain par la mise en œuvre de nouvelles technologies, dans des visées d’augmentation des capacités humaines et de prolongation importante de la vie. Né en Californie en 1988, il a diffusé ses thématiques dans le monde entier. S’il est l’objet de nombreuses études philosophiques, éthiques, théologiques, politiques, sociologiques, il a peu suscité de recherches proprement historiques, notamment de son mouvement. Or l’histoire du mouvement permet de mieux cerner ce qu’est le transhumanisme – entre controverse, mouvance et mouvement – et ce qui constitue sa structure idéologique. Une telle approche s’appuie sur la confrontation des publications, des traces numériques du mouvement et des trajectoires de ses membres.
Reducing Hydrogen Embrittlement Risk of Steel Bolting in Seawater Environment with Nickel-Cobalt Electroplating
Authors: Rosas Omar , Burk James D. , Garcia Oscar , Hernandez Jose , Girault Carlos 
Published: April 2018

AbstractAmongst all the several threats derived from corrosion in bolting in marine environments, hydrogen embrittlement is perhaps one of the most dreaded. Hydrogen embrittlement is a form of environmentally assisted cracking (EAC) where hydrogen generated from different sources penetrates inside the basematerial and makes it more fragile. This paper addresses the severity of the environment and the influence of different metallic coatings on the amount of hydrogen present in the base substrate steel bolting. From laboratory generated data, environmental severity and risk of hydrogen embrittlement are estimated and correlated to actual field performance from the literature. This investigation relates the interplay of environment, stress, and materials.The metallic coatings evaluated in this investigation are: Zinc, Zinc-Nickel, and Nickel-Cobalt ASTM B994, the two formers are typical coatings currently used in bolting in Oil and Gas, the latter is a novel material with offshore applications including subsea environments. Cracking resistance of the AISI 4130/4140 and 4340 also specified as ASTM A193 B7/B7M, L7/L7M and L43 studs or bolts and ASTM A194 nuts, all referred to as bolting, is characterized in terms of the variation in environmental severity. The environmental severity is measured by both, Devanathan–Stachurski cell technique to measure the amount of hydrogen absorbed into the steels substrate across the coatings, and the use of Tafel scans of the coatings and a Pourbaix diagram to measure Ecorr and amount of hydrogen generated. From these results, the metallic plated coatings are ranked as to environmental severity relative to each other.The results showed an outstanding performance of the Nickel-Cobalt coating compared to the sacrificial coatings. Sacrificial coatings produced large amounts of hydrogen in the cathodic reaction and allowed its penetration to the base-material; Nickel-Cobalt did not produce hydrogen at OCP and the permeation was much lower than in the other materials under cathodic charging conditions. The results of mechanical testing showed that Nickel-Cobalt is not affected by the cathodic charging whilst the tested sacrificial coatings reduce their mechanical resistance in a 50%; these results mean that hydrogen permeation into Nickel-Cobalt is negligible, even after being subject to high cathodic charging. Nickel-Cobalt alloy ASTM B994 is proposed as the emerging technology for carbon and high strength steel bolts to be used in marine environment and subsea where failure is not an option.The results from this effort have an outstanding relevance in offshore and subsea deep-water drilling and production equipment that depends on high strength carbon and low allow steels. This work addresses failures caused by hydrogen embrittlement that have been documented by the American Petroleum Institute (API) and the Bureau of Safety and Environmental Enforcement (BSEE).
