Authors: Al-Tayar Badr Abdullah Saeed , Tin-Oo Mon Mon , Sinor Mohd Zulkarnain , Hussein Abdikarim Mohamed , Al-ak’hali Mohammed Sultan 
Published: November 2017

Background:
Toombak is a traditional type of smokeless tobacco used by people in Yemen, especially in Dawan Valley, Hadramout Province, Yemen. The use of smokeless tobacco may be considered as a predisposing risk factor for several oral diseases.

Case Presentation:
This paper presents two cases. The first is that of a 27-year-old male toombak user with severe periodontitis and oral melanosis. The second case is that of a 44-year-old male toombak user with oral hypermelanosis. The patients were subjected to dental cleaning. Quit toombak counseling was conducted, and the patients were educated about the adverse effects of toombak usage.

Conclusion:
Oral tissues are severely affected by toombak usage. Thus, comprehensive toombak prevention programs should be implemented to reduce toombak-associated diseases.

Abstract
A main goal of NASA’s Kepler Mission is to establish the frequency of potentially habitable Earth-size planets (

). Relatively few such candidates identified by the mission can be confirmed to be rocky via dynamical measurement of their mass. Here we report an effort to validate 18 of them statistically using the BLENDER technique, by showing that the likelihood they are true planets is far greater than that of a false positive. Our analysis incorporates follow-up observations including high-resolution optical and near-infrared spectroscopy, high-resolution imaging, and information from the analysis of the flux centroids of the Kepler observations themselves. Although many of these candidates have been previously validated by others, the confidence levels reported typically ignore the possibility that the planet may transit a star different from the target along the same line of sight. If that were the case, a planet that appears small enough to be rocky may actually be considerably larger and therefore less interesting from the point of view of habitability. We take this into consideration here and are able to validate 15 of our candidates at a 99.73% (3σ) significance level or higher, and the other three at a slightly lower confidence. We characterize the GKM host stars using available ground-based observations and provide updated parameters for the planets, with sizes between 0.8 and 2.9 R
⊕. Seven of them (KOI-0438.02, 0463.01, 2418.01, 2626.01, 3282.01, 4036.01, and 5856.01) have a better than 50% chance of being smaller than 2 R
⊕ and being in the habitable zone of their host stars.

Abstract
We study the heating mechanisms and Lyα escape fractions of 35 Lyα blobs (LABs) at z ≈ 3.1 in the SSA22 field. Dust continuum sources have been identified in 11 of the 35 LABs, all with star formation rates (SFRs) above 100 M
⊙ yr−1. Likely radio counterparts are detected in 9 out of 29 investigated LABs. The detection of submillimeter dust emission is more linked to the physical size of the Lyα emission than to the Lyα luminosities of the LABs. A radio excess in the submillimeter/radio-detected LABs is common, hinting at the presence of active galactic nuclei. Most radio sources without X-ray counterparts are located at the centers of the LABs. However, all X-ray counterparts avoid the central regions. This may be explained by absorption due to exceptionally large column densities along the line-of-sight or by LAB morphologies, which are highly orientation dependent. The median Lyα escape fraction is about 3% among the submillimeter-detected LABs, which is lower than a lower limit of 11% for the submillimeter-undetected LABs. We suspect that the large difference is due to the high dust attenuation supported by the large SFRs, the dense large-scale environment as well as large uncertainties in the extinction corrections required to apply when interpreting optical data.
AT 2017gfo: An Anisotropic and Three-component Kilonova Counterpart of GW170817
Authors: Perego Albino , Radice David , Bernuzzi Sebastiano 
Published: November 2017

Abstract
The detection of a kilo/macronova electromagnetic counterpart (AT 2017gfo) of the first gravitational-wave signal compatible with the merger of two neutron stars (GW170817) has confirmed the occurrence of r-process nucleosynthesis in this kind of event. The blue and red components of AT 2017gfo have been interpreted as the signature of multi-component ejecta in the merger dynamics. However, the explanation of AT 2017gfo in terms of the properties of the ejecta and of the ejection mechanisms is still incomplete. In this work, we analyze AT 2017gfo with a new semi-analytic model of kilo/macronova inferred from general-relativistic simulations of the merger and long-term numerical models of the merger aftermath. The model accounts for the anisotropic emission from the three known mass ejecta components: dynamic, winds, and secular outflows from the disk. The early multi-band light curves of AT 2017gfo can only be explained by the presence of a relatively low-opacity component of the ejecta at high latitudes. This points to the key role of weak interactions in setting the ejecta properties and determining the nucleosynthetic yields. Our model also constrains the total ejected mass associated to AT 2017gfo to be between 0.042 and 0.077

Published: November 2017

Abstract
We present observations of the interstellar interloper 1I/2017 U1 (’Oumuamua) taken during its 2017 October flyby of Earth. The optical colors B – V = 0.70 ± 0.06, V – R = 0.45 ± 0.05, overlap those of the D-type Jovian Trojan asteroids and are incompatible with the ultrared objects that are abundant in the Kuiper Belt. With a mean absolute magnitude H

V
= 22.95 and assuming a geometric albedo p

V
= 0.1, we find an average radius of 55 m. No coma is apparent; we deduce a limit to the dust mass production rate of only ∼2 × 10−4 kg s−1, ruling out the existence of exposed ice covering more than a few m2 of the surface. Volatiles in this body, if they exist, must lie beneath an involatile surface mantle ≳0.5 m thick, perhaps a product of prolonged cosmic-ray processing in the interstellar medium. The light curve range is unusually large at ∼2.0 ± 0.2 mag. Interpreted as a rotational light curve the body has axis ratio

:1 and semi-axes ∼230 m × 35 m. A ≳6:1 axis ratio is extreme relative to most small solar system asteroids and suggests that albedo variations may additionally contribute to the variability. The light curve is consistent with a two-peaked period ∼8.26 hr, but the period is non-unique as a result of aliasing in the data. Except for its unusually elongated shape, 1I/2017 U1 is a physically unremarkable, sub-kilometer, slightly red, rotating object from another planetary system. The steady-state population of similar, ∼100 m scale interstellar objects inside the orbit of Neptune is ∼104, each with a residence time of ∼10 years.
La fin de la discipline partisane
Authors: Reignier Dorothée 
Published: November 2017

Les nombreuses divisions qui ont émaillé la XIV e législature conduisent à s’interroger sur la possible fin de la discipline partisane. L’ampleur de la fronde et la contestation des consignes, y compris au sein du premier parti d’opposition, conduisent à valider cette hypothèse. Le rejet de la discipline partisane semble ainsi définitif, à moins que la nouvelle législature n’en réinvente les codes.
Entre André Green et Pierre Marty, la psychosomatique
Authors: Jaeger Philippe 
Published: November 2017

Green rapproche la psychose blanche et la dépression essentielle et comprend la crise somatique comme acting out orienté vers le dedans. Green utilise Les modèles de Bion et de Winnicott comme des intermédiaires pour travailler au dépassement de l’écrasement du champ psychique. L’hypothèse princeps de Green concernant la psycho­somatique est le clivage de l’ensemble pulsion-objet, par opposition à la régression archaïque du lien sujet objet maintenu dans la psychose.
Penser la psychosomatique avec les concepts d’André Green
Authors: Duparc François 
Published: November 2017

Sans être un psychosomaticien avéré, André Green était proche de la psychosomatique française et de P. Marty. Ses points de convergences sont l’affect, pour lutter contre la focalisation sur la parole des freudiens et des lacaniens en France, ainsi que l’hallucination négative du corps et de l’émotion, et la clinique du vide laissé par la mère morte. Sa notion de « vécus irreprésentables » faute d’un objet pour la pulsion le conduit à privilégier la motion pulsionnelle, embryon d’intentionnalité psychosomatique. La forclusion de certains fantasmes originaires peut être déduite de ses idées sur les mouvements pré-psychiques, en lien avec les lignées psychosomatiques de M. Fain.
Diminutieven van basissen op een vocaal of glijder in de centraal-zuidelijke en de zuidwestelijke dialecten. Een precisering

Abstract

Diminutives of bases on a vowel or glide in central southern and south western dialects: a specification

The excellent first part of the Morphological Atlas of the Dutch Dialects (MAND 2005) discusses the formation of diminutives in Dutch dialects, taking diminutives of bases ending on 'vowel, diphtong or glide' as a point of reference, 'after which the diminutive suffix can develop freely and most naturally.' Based on data from central southern and southwestern dialects, this article presents a more precise account, in which bases ending on a monophtong are contrasted with bases ending on diphtongs and glides.
Integrating Herbivore Population Dynamics Into a Global Land Biosphere Model: Plugging Animals Into the Earth System

Published: November 2017

AbstractMammalian herbivores are an essential component of grassland and savanna ecosystems, and with feedbacks to the climate system. To date, the response and feedbacks of mammalian herbivores to changes in both abiotic and biotic factors are poorly quantified and not adequately represented in the current global land surface modeling framework. In this study, we coupled herbivore population dynamics in a global land model (the Dynamic Land Ecosystem Model, DLEM 3.0) to simulate populations of horses, cattle, sheep, and goats, and their responses to changes in multiple environmental factors at the site level across different continents during 1980–2010. Simulated results show that the model is capable of reproducing observed herbivore population dynamics across all sites for these animal groups. Our simulation results also indicate that during this period, climate extremes led to a maximum mortality of 27% of the total herbivores in Mongolia. Across all sites, herbivores reduced aboveground net primary productivity (ANPP) and heterotrophic respiration (Rh) by 14% and 15%, respectively (p < 0.05). With adequate parameterization, the model can be used for historical assessment and future prediction of mammalian herbivore populations and their relevant impacts on biogeochemical cycles. Our simulation results demonstrate a strong coupling between primary producers and consumers, indicating that inclusion of herbivores into the global land modeling framework is essential to better understand the potentially large effect of herbivores on carbon cycles in grassland and savanna ecosystems.
Subsurface Nonlinear Dynamical Heating and ENSO Asymmetry
Authors: Hayashi Michiya , Jin Fei‐Fei 
Published: November 2017

AbstractThis study presents evidence of interannual to interdecadal variabilities residing in the subsurface nonlinear dynamical heating (NDH) along the equatorial Pacific thermocline based on ocean reanalysis products. In association with a flattened thermocline and drastic halt of the Equatorial Undercurrent, the NDH increases sharply right after a peak of the strong El Niño, reducing the linear anomalous advective subsurface cooling by 30%. As the result, subsurface cold signals in the west are significantly weakened as it reaches the easternmost Pacific, causing less surface cooling in the east and thus weakening the subsequent La Niña. Therefore, the subsurface NDH contributes to asymmetry in both the magnitude and structure between El Niño and La Niña. The acute positive subsurface NDH associated with strong El Niño events leads to substantial variations in its decadal means and serves as a potential source for tropical Pacific decadal to interdecadal variabilities.
The Influence of Hydraulic Fracturing on Carbon Storage Performance
Authors: Fu Pengcheng , Settgast Randolph R. , Hao Yue , Morris Joseph P. , Ryerson Frederick J. 
Published: November 2017

AbstractConventional principles of the design and operation of geologic carbon storage (GCS) require injecting CO2 below the caprock fracturing pressure to ensure the integrity of the storage complex. In nonideal storage reservoirs with relatively low permeability, pressure buildup can lead to hydraulic fracturing of the reservoir and caprock. While the GCS community has generally viewed hydraulic fractures as a key risk to storage integrity, a carefully designed stimulation treatment under appropriate geologic conditions could provide improved injectivity while maintaining overall seal integrity. A vertically contained hydraulic fracture, either in the reservoir rock or extending a limited height into the caprock, provides an effective means to access reservoir volume far from the injection well. Employing a fully coupled numerical model of hydraulic fracturing, solid deformation, and matrix fluid flow, we study the enabling conditions, processes, and mechanisms of hydraulic fracturing during CO2 injection. A hydraulic fracture's pressure‐limiting behavior dictates that the near‐well fluid pressure is only slightly higher than the fracturing pressure of the rock and is insensitive to injection rate and mechanical properties of the formation. Although a fracture contained solely within the reservoir rock with no caprock penetration, would be an ideal scenario, poroelastic principles dictate that sustaining such a fracture could lead to continuously increasing pressure until the caprock fractures. We also investigate the propagation pattern and injection pressure responses of a hydraulic fracture propagating in a caprock subjected to heterogeneous in situ stress. The results have important implications for the use of hydraulic fracturing as a tool for managing storage performance.
Role of Compressibility on Tsunami Propagation
Authors: Abdolali Ali , Kirby James T. 
Published: November 2017

AbstractIn the present paper, we aim to reduce the discrepancies between tsunami arrival times evaluated from tsunami models and real measurements considering the role of ocean compressibility. We perform qualitative studies to reveal the phase speed reduction rate via a modified version of the Mild Slope Equation for Weakly Compressible fluid (MSEWC) proposed by Sammarco et al. (2013). The model is validated against a 3‐D computational model. Physical properties of surface gravity waves are studied and compared with those for waves evaluated from an incompressible flow solver over realistic geometry for 2011 Tohoku‐oki event, revealing reduction in phase speed.
Deep Bering Sea Circulation and Variability, 2001–2016, From Argo Data
Authors: Johnson Gregory C. , Stabeno Phyllis J. 
Published: November 2017

AbstractThe mean structure, seasonal cycle, and interannual variability of temperature and salinity are analyzed in the deep Bering Sea basin using Argo profile data collected from 2001 to 2016. Gyre transports are estimated using geostrophic stream function maps of Argo profile data referenced to a 1,000 dbar nondivergent absolute velocity stream function mapped from Argo parking pressure displacement data. Relatively warm and salty water from the North Pacific enters the basin through the Near Strait and passages between Aleutian Islands to the east. This water then flows in a cyclonic (counterclockwise) direction around the region, cooling (and freshening) along its path. Aleutian North Slope Current transports from 0 to 1,890 dbar are estimated at 3–6 Sverdrups (1 Sv = 106 m3 s−1) eastward, feeding into the northwestward Bering Slope Current with transports of mostly 5–6 Sv. The Kamchatka Current has transports of ∼6 Sv north of Shirshov Ridge, increasing to 14–16 Sv south of the ridge, where it is augmented by westward flow from Near Strait. Temperature exhibits strong interannual variations in the upper ocean, with warm periods in 2004–2005 and 2015–2016, and cold periods around 2009 and 2012. In contrast, upper ocean salinity generally decreases from 2001 to 2016. As a result of this salinity decrease, the density of the subsurface temperature minimum decreased over this time period, despite more interannual variability in the minimum temperature value. The subsurface temperature maximum also exhibits interannual variability, but with values generally warmer than those previously reported for the 1970s and 1980s.
Diurnal Forcing Induces Variations in Seasonal Temperature and Its Rectification Mechanism in the Eastern Shelf Seas of China
Authors: Yu Yang , Gao Huiwang , Shi Jie , Guo Xinyu , Liu Guangliang 
Published: November 2017

AbstractThis study investigates the seasonal variation in temperature induced by diurnal forcing in the eastern shelf seas of China (ESSC) using a high‐resolution Regional Ocean Modeling System model forced by the National Center for Environmental Prediction and the National Center for Atmospheric Research re‐analysis data for surface fluxes with both 6 h and daily frequencies, respectively. The comparison between two experiments revealed a
modification of the variation in seasonal temperature by diurnal forcing, which also increases the mixed‐layer depth (MLD) in August by 26% and reduces the volume of the Yellow Sea Cold Water Mass (YSCWM) by 25%. Sensitivity experiments using different forcing variables indicated that diurnal wind can explain over 80% of the variability in seasonal temperature induced by diurnal forcing. Diurnal wind led to an increase in the net heat flux into the ocean by about 13
in summer and a decrease by about 15
in winter. Diurnal wind also generated an additional downward heat transport of 21
over the ESSC that contributed to variability in the mean MLD and YSCWM in August. Experiments changing the temporal interval of wind forcing suggested that the increase in the forcing temporal interval gradually enhanced the reproduction of the variability in seasonal temperature generated by diurnal wind; a 6 h wind forcing can capture 70% of this type of variability given by 1 h wind forcing, while a 3 h or shorter wind forcing can capture 90%.
Eddy‐Kuroshio Interactions: Local and Remote Effects
Authors: Jan Sen , Mensah Vigan , Andres Magdalena , Chang Ming‐Huei , Yang Yiing Jang 
Published: November 2017

AbstractQuasi‐geostrophic mesoscale eddies regularly impinge on the Kuroshio in the western North Pacific, but the processes underlying the evolution of these eddy‐Kuroshio interactions have not yet been thoroughly investigated in the literature. Here this interaction is examined with results from a semi‐idealized three‐dimensional numerical model and observations from four pressure‐sensor equipped inverted echo sounders (PIESs) in a zonal section east of Taiwan and satellite altimeters. Both the observations and numerical simulations suggest that, during the interaction of a cyclonic eddy with the Kuroshio, the circular eddy is deformed into an elliptic shape with the major axis in the northwest‐southeast direction, before being dissipated; the poleward velocity and associated Kuroshio transport decrease and the sea level and pycnocline slopes across the Kuroshio weaken. In contrast, for an anticyclonic eddy during the eddy‐Kuroshio interaction, variations in the velocity, sea level, and isopycnal depth are reversed; the circular eddy is also deformed to an ellipse but with the major axis parallel to the Kuroshio. The model results also demonstrate that the velocity field is modified first and consequently the SSH and isopycnal depth evolve during the interaction. Furthermore, due to the combined effect of impingement latitude and realistic topography, some eddy‐Kuroshio interactions east of Taiwan are found to have remote effects, both in the Luzon Strait and on the East China Sea shelf northeast of Taiwan.
Controlling Pulsed EM Scattering of a One‐Port Receiving Antenna
Authors: Štumpf Martin 
Published: November 2017

AbstractA time domain compensation theorem concerning electromagnetic (EM) scattering of a one‐port antenna system is derived with the aid of the reciprocity theorem of the time convolution type. The theorem describes the impact of a change in the antenna load on receiving antenna scattering properties. The compensation theorem is next applied to express the change of the copolarized backscattered far‐field amplitude in terms of (local) Kirchhoff circuit quantities excited in the corresponding receiving scenarios. Applications of the results can be found in controlling the pulsed echo of a receiving antenna as well as in related theoretical aspects of receiving antenna scattering theory. Illustrative numerical results are given for both linear and nonlinear antenna loads.
