Trends in the Prevalence of Psychological Distress Over Time: Comparing Results From Longitudinal and Repeated Cross-Sectional Surveys
Authors: Butterworth Peter , Watson Nicole , Wooden Mark 
Published: November 2020

Background: While there is discussion of increasing rates of mental disorders, epidemiological research finds little evidence of change over time. This research generally compares cross-sectional surveys conducted at different times. Declining response rates to representative surveys may mask increases in mental disorders and psychological distress.Methods: Analysis of data from two large nationally representative surveys: repeated cross-sectional data from the Australian National Health Survey (NHS) series (2001–2017), and longitudinal data (2007–2017) from the Household, Income and Labor Dynamics in Australia (HILDA) Survey. Data from each source was used to generate weighted national estimates of the prevalence of very high psychological distress using the Kessler Psychological Distress scale (K10).Results: Estimates of the prevalence of very high psychological distress from the NHS were stable between 2001 and 2014, with a modest increase in 2017. In contrast, the HILDA Survey data demonstrated an increasing trend over time, with the prevalence of very high distress rising from 4.8% in 2007 to 7.4% in 2017. This increase was present for both men and women, and was evident for younger and middle aged adults but not those aged 65 years or older. Sensitivity analyses showed that this increase was notable in the upper end of the K10 distribution.Conclusions: Using household panel data breaks the nexus between declining survey participation rates and time, and suggests the prevalence of very high psychological distress is increasing. The study identifies potential challenges in estimating trends in population mental health using repeated cross-sectional survey data.
Complete Osseointegration of a Retrieved 3-D Printed Porous Titanium Cervical Cage
Authors: van den Brink Wimar , Lamerigts Nancy 
Published: November 2020

Introduction: Porous 3D-printed titanium has only recently been introduced for spinal applications. Evidence around its use is currently limited to animal studies and only few human case series. This study describes the histological findings of a retrieved EIT cervical cage, explanted 2 years after insertion.Materials and Methods: The patient underwent a double level C4/C5 &amp; C5/C6 anterior cervical decompression using EIT cervical cages without an anterior plate. Two years later the C6/7 level degenerated and began to cause myelopathic symptoms. In order to address the kyphotic imbalance of the cervical spine and fix the C6/7 level, the surgeon decided to remove the C5/6 cervical cage and bridge the fusion from C4 to C7 inclusive. The retrieved cage was histologically evaluated for bone ingrowth and signs of inflammation.Results: MRI demonstrated spinal canal stenosis at C6/C7. Plain radiographs confirmed well-integrated cervical cages at 2 years postoperative. The peroperative surgical need to use a chisel to remove the implant at C5/C6 reconfirmed the solid fusion of the segment. Macroscopically white tissue, indicative of bone, was present at both superior and inferior surfaces of the explanted specimen. Histological evaluation revealed complete osseointegration of the 5 mm high EIT Cellular Titanium® cervical cage, displaying mature lamellar bone in combination with bone marrow throughout the cage. Furthermore, a pattern of trabecular bone apposition (without fibrous tissue interface) and physiological remodeling activity was observed directly on the cellular titanium scaffold.Conclusion: This histological retrieval study of a radiologically fused cervical EIT cage clearly demonstrates complete osseointegration within a 2-year time frame. The scaffold exhibits a bone in growth pattern and maturation of bone tissue similar of what has been demonstrated in animal studies evaluating similar porous titanium implants. The complete osseointegration throughout the cage indicates physiological loading conditions even in the central part of the cage. This pattern suggests the absence, or at least the minimization, of stress-shielding in this type of porous titanium cage.
Highly efficient asymmetric optical transmission based on the gradient metasurface and subwavelength grating
Authors: Wu Mingxuan , Liao Qinghua 
Published: November 2020

Abstract
In this paper, an asymmetric transmission device by combining the gradient metasurface and the subwavelength grating is proposed and investigated numerically. The gradient metasurface produces a transmitted wave with a certain angle upon normal incidence. The subwavelength grating can block light under the condition of normal incidence, although it can transmit light with an angle realized by the gradient metasurface. All materials employed in the proposed device are dielectric. The asymmetric transmission device exhibits high working efficiency and possesses a high-contrast ratio up to 41 dB. Our results are beneficial in designing devices with high-performance asymmetric optical transmission.

Abstract
We present the clustering properties of low-z (z ≤ 1.4) galaxies selected by the Hyper Suprime-Cam Subaru Strategic Program Wide layer over 145 deg2. The wide-field and multiwavelength observation yields 5,064,770 galaxies at 0.3 ≤ z ≤ 1.4 with photometric redshifts and physical properties. This enables the accurate measurement of angular correlation functions, and the subsequent halo occupation distribution (HOD) analysis allows us to identify the connection between baryonic and dark halo properties. The fraction of less-massive satellite galaxies at z ≲ 1 is found to be almost constant at ∼20%, but it gradually decreases beyond

. However, the abundance of satellite galaxies at z > 1 is quite small even for less-massive galaxies due to the rarity of massive centrals at high-z. This decreasing trend is connected to the small satellite fraction of Lyman break galaxies at z > 3. The stellar-to-halo mass ratios at 0.3 ≤ z ≤ 1.4 are almost consistent with the predictions obtained using the latest empirical model; however, we identify small excesses from the theoretical model at the massive end. The pivot halo mass is found to be unchanged at

at 0.3 ≤ z ≤ 1.4, and we systematically show that

is a universal pivot halo mass up to z ∼ 5 that is derived using only the clustering/HOD analyses. Nevertheless, halo masses with peaked instantaneous baryon conversion efficiencies are much smaller than the pivot halo mass regardless of redshift, and the most efficient stellar-mass assembly is thought to be in progress in

dark halos.
The Effect of Land Albedo on the Climate of Land-dominated Planets in the TRAPPIST-1 System
Authors: Rushby Andrew J. , Shields Aomawa L. , Wolf Eric T. , Laguë Marysa , Burgasser Adam 
Published: November 2020

Abstract
Variations in the reflective properties of the bulk material that comprises the surface of land-dominated planets will affect the planetary energy balance by interacting differently with incident radiation from the host star. Furthermore, low-mass cool stars, such as nearby M8V dwarf TRAPPIST-1, emit a significant fraction of their flux in longer wavelengths relative to the Sun in regions where terrestrial materials may exhibit additional variability in albedo. Using the Community Earth System Model, we investigate the effect of the composition of the land surface and its albedo on planetary climate in the context of spatially homogeneous, entirely land-covered planets with dry atmospheres at the orbital separation of TRAPPIST-1d, TRAPPIST-1e, and TRAPPIST-1f. We use empirically derived spectra of four terrestrial compositional endmembers (granite, calcite, aridisol, and dune sand) and a composite spectrum of TRAPPIST-1 for these simulations and compare these model outputs to an aquaplanet and several Sol-spectrum control cases. We report a difference of approximately 50 K in global mean surface temperature, variations in atmospheric rotational features, and a reduction in cross-equatorial heat transport between scenarios in which materials with higher albedo in the infrared (calcite and dune sand) were used and those with more absorptive crustal material, such as granite or dry soils. An aquaplanet TRAPPIST-1d scenario results in an unstable runaway greenhouse regime. Therefore, we demonstrate that determining the composition and albedo of continental landmasses is crucial for making accurate determinations of the climate of terrestrial exoplanets.
Gamma-Ray Emission Revealed at the Western Edge of SNR G344.7–0.1

Published: November 2020

Abstract
We report on the investigation of a very high energy (VHE), Galactic γ-ray source recently discovered at >50 GeV using the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi). This object, 2FHL J1703.4–4145, displays a very hard >50 GeV spectrum with a photon index Γ
γ
∼ 1.2 in the 2FHL catalog and, as such, is one of the most extreme sources in the 2FHL subsample of Galactic objects. A detailed analysis of the available multiwavelength data shows that this source is located on the western edge of the supernova remnant (SNR) G344.7–0.1, along with extended TeV source, HESS J1702–420. The observations and the spectral energy distribution modeling support a scenario where this γ-ray source is the byproduct of the interaction between the SNR shock and the dense surrounding medium, with escaping cosmic rays (CRs) diffusing into the dense environment and interacting with a large local cloud, generating the observed TeV emission. If confirmed, an interaction between the SNR CRs and a nearby cloud would make 2FHL J1703.4–4145 another promising candidate for efficient particle acceleration of the 2FHL Galactic sample, following the first candidate from our previous investigation of a likely shock–cloud interaction occurring on the western edge of the Vela SNR.
Whether Small Flux Ropes and Magnetic Clouds Have the Same Origin: A Statistical Study of Small Flux Ropes in Different Types of Solar Wind

Published: November 2020

Abstract
According to the duration and size, magnetic flux ropes can be divided into large-scale flux ropes, namely, magnetic clouds, and small-scale flux ropes (SFRs). Whether SFRs have the same origin as magnetic clouds has been a hot topic for a long time. Based on the SFR database developed by Hu et al. and Chen et al., this paper analyzes the properties of SFRs in different types of solar wind, which are SFRs in interplanetary coronal mass ejections (ICMEs), SFRs in stream interaction regions, and SFRs in background solar wind. On the assumption that SFRs in ICMEs have the same origin as magnetic clouds, we compare the three types of SFRs from several aspects, attempting to shed some light on the dispute, i.e., whether SFRs are homologous to magnetic clouds. The results show that up to 91% of the SFRs are outside ICMEs. Unlike SFRs in ICMEs, SFRs outside ICMEs seldom have large magnetic field strength and apparent expansion signatures. In addition, 36% of the SFRs in ICMEs have enhanced iron charge states. This probability is much higher than the other two types of SFRs. By an automatic method, this paper also find that counterstreaming electrons are more common in SFRs in ICMEs. Considering strong magnetic field, expansion signatures, large iron charge state, and counterstreaming electrons are important indicators of magnetic clouds, we believe that most of the SFRs near Earth have different origins from magnetic clouds.
Kink Oscillations in Solar Coronal Loops with Elliptical Cross Sections. I. The Linear Regime
Authors: Guo Mingzhe , Li Bo , Van Doorsselaere Tom 
Published: November 2020

Abstract
The cross sections of solar coronal loops are suggested to be rarely circular. We examine linear kink oscillations in straight, density-enhanced, magnetic cylinders with elliptical cross sections by solving the three-dimensional magnetohydrodynamic equations from an initial-value-problem perspective. Motivated by relevant eigenmode analyses, we distinguish between two independent polarizations, one along the major axis (the M-modes) and the other along the minor one (the m-modes). We find that, as happens for coronal loops with circular cross sections, the apparent damping of the transverse displacement of the loop axis is accompanied by the accumulation of transverse Alfvénic motions and the consequent development of small scales therein, suggesting the robustness of the concepts of resonant absorption and phase mixing. In addition, two stages can in general be told apart in the temporal evolution of the loop displacement: a Gaussian time dependence precedes an exponential one. For the two examined density ratios between loops and their surroundings, the periods of the M-modes (m-modes) tend to increase (decrease) with the major-to-minor-half-axis ratio, and the damping times in the exponential stage for the M-modes tend to exceed their m-mode counterparts. This is true for the two transverse profiles we examine. However, the relative magnitudes of the damping times in the exponential stage for different polarizations depend on the specification of the transverse profile or the density contrast. The applications of our numerical findings are discussed in the context of coronal seismology.

Published: November 2020

Abstract
The existence of long-lived galaxies lacking dark matter represents a challenge to our understanding of how galaxies form. Here, we present evidence that explains the lack of dark matter in one such galaxy: NGC 1052-DF4. Deep optical imaging of the system has detected tidal tails in this object caused by its interaction with its neighboring galaxy NGC 1035. As stars are more centrally concentrated than dark matter, tidal stripping will remove a significant percentage of dark matter before affecting the stars of the galaxy. Only

of the stellar mass of the galaxy is in the tidal tails, suggesting that the stars of NGC 1052-DF4 are only now starting to be affected by the interaction, while the percentage of remaining dark matter is

. This naturally explains the low content of dark matter inferred for this galaxy and reconciles these types of galaxies with our current models of galaxy formation.
Le passage cénomanien-turonien dans les Monts des Ksour (Atlas Saharien Occidental, Algérie): biostratigraphie, géochimie et milieux de dépôt

[fr] Dans les Monts des Ksour (Atlas saharien occidental), le passage cénomanien-turonien a été étudié sur le plan stratigraphique et géochimique à partir de deux coupes: Djebel M’daouer et Chebket Tamednaïa. Dans ces deux coupes, comme sur la plupart des plates-formes carbonatées peu profondes du domaine sud-téthysien, le faciès anoxique de la limite cénomanien-turonien matérialisé par des dépôts de “black-shales“ est absent. En plus, la rareté des données biostratigraphiques rend difficile l’établissement d’une biozonation détaillée pour les deux coupes étudiées. Les deux seuls niveaux à rares ammonites de la Formation de Ghoundjaïa dans la coupe de M’daouer ont permis de caractériser les zones à Vibrayeanus, à Gamai et à Cauvini. Donc pour les deux coupes, il parait utile de recourir à l’étude isotopique qui a montré une zone d’excursion positive du δ 13C s’étalant le long du Membre inférieur et la partie inférieure du Membre médian de la Formation de Ghoundjaïa. Cette zone d’anomalie est manifestée par trois pics marquants et caractéristiques du passage cénomanien-turonien et la limite entre ces deux étages se situe entre les pics 2 et 3 coïncidant avec le passage de la zone Gamai à la zone Cauvini. L’enregistrement de ces trois pics a rendu possible la corrélation locale de la coupe de Tamednaïa qui est dépourvue de faune valable sur le plan biostratigraphique.
Wettability on Different Surfaces
Authors: Kelvii Kwok Yeeli 
Published: November 2020

Wettability has been explored for 100 years since it is described by Young’s equation in 1805. It is all known that hydrophilicity means contact angle (θ), θ < 90°; hydrophobicity means contact angle (θ), θ > 90°. The utilization of both hydrophilic surfaces and hydrophobic surfaces has also been achieved in both academic and practical perspectives. In order to understand the wettability of a droplet distributed on the textured surfaces, the relevant models are reviewed along with understanding the formation of contact angle and how it is affected by the roughness of the textured surface aiming to obtain the required surface without considering whether the original material is hydrophilic or hydrophobic.
