Background: Malnutrition is a public health problem, especially in developing countries. Malnutrition of children can affect brain development during growth and increase morbidity and mortality. Low birth weight (LBW) plays an important role in child morbidity and mortality. The prevalence of malnutrition in children under five years old and LBW in Indonesia are still high.Objective: This study aimed to assess the risk of LBW on the incidence of malnutrition in children under five years old in coastal areas.Method: This was an observational analytic study with case control approach. The study was conducted on 64 respondents in the coastal area of Kendari City, Southeast Sulawesi on November to December 2018. Case group (n=16) was children under five years old who experienced malnutrition in the working area of Abeli, Mata and Benu-Benua Health Center in October 2018. Control group (n=48) was taken by measuring body weight and then adjusted to the category and threshold of nutritional status based on the body weight index according to age. Sixteen respondents of case group were recruited using total sampling. Forty-eight respondents of control group were also recruited using purposive sampling with non-matching method according to the inclusion and exclusion criteria. The Odd Ratio (OR) statistical test was used with a 2x2 contingency table and a 95% confidence level with a significance level of α = 0.05.Results: The majority of respondents were 25-48 months old, and maternal age was mostly 36-45 years old in the case group (37.5%) and 26-35 years old in the control group (50.0%). The majority of maternal education level was junior high school in the case group (43.7%) and high school in the control group (47.9%). The statistical test results were obtained OR = 5.923 (CI=95%) with Lower Limit (1.724) and Upper Limit (20.346). Conclusion: Infants with LBW had a 5 times higher risk for experiencing malnutrition in childhood in coastal areas. Therefore, knowledge of LBW and malnutrition is needed to improve public health status.
An Assessment of Contamination in the Thermal-SZ Map Using Cross-correlations
Authors: Yan 颜子 Ziang 昂 , Hojjati Alireza , Tröster Tilman , Hinshaw Gary , Waerbeke Ludovic van 
Published: October 2019

Abstract
We search for potential galactic and extragalactic dust contamination in thermal Sunyaev–Zeldovich maps derived from the Planck data. To test for contamination, we apply a variety of galactic dust and cosmic infrared background (CIB) models to the data as part of the y map reconstruction process. We evaluate the level of contamination by cross-correlating these y maps with mass tracers based on weak lensing data. The lensing data we use are the convergence map, κ, from the Red Sequence Cluster Lensing survey, and the cosmic microwave background (CMB) lensing potential map, ϕ, from the Planck Collaboration. We make a CIB-subtracted y map and measure the cross-correlation between it and the lensing data. By comparing it with CIB-contaminated cross-correlation, we find that the cross-correlation between κ and y is only slightly contaminated by CIB signal, at the level of 6.8 ± 3.5%, which implies that previous detections of κ × y are robust to CIB contamination. However, we find that ϕ × y is more significantly contaminated, by 16.7 ± 3.5%, because the CMB lensing potential probes higher redshift sources that overlap more with the CIB sources. We find that Galactic dust does not significantly contaminate either cross-correlation signal.
Mapping the Galactic Disk with the LAMOST and Gaia Red Clump Sample. III. A New Velocity Substructure and Time Stamps of the Galactic Disk Asymmetry in the Disk between 12 and 15 kpc

Abstract
We investigate the three-dimensional asymmetrical kinematics and present time stamps of the Milky Way disk between Galactocentric distances of R = 12 and 15 kpc, using red clump stars selected from the LAMOST Galactic survey, also with proper motion measurements provided by the Gaia DR2. We discover velocity substructure above the Galactic plane corresponding to a density dip found recently (“South-middle opposite” density structure [R ∼ 12–15 kpc, Z ∼ 1.5 kpc] discovered in Wang et al.) in the radial and azimuthal velocity. For the vertical velocity, we detect clear vertical bulk motions or bending mode motions, which has no clear North–South asymmetry corresponding to the in-plane asymmetrical features. In the subsample of stars with different ages, we find that there is little temporal evolution of the in-plane asymmetry from 0 to 14 Gyr, which means the structure is possibly sensitive to the perturbations in almost cosmic time. We propose that the possible scenario of this asymmetric velocity structure is caused by the mechanisms generated in-plane, rather than vertical perturbations.
Identifying Kinematic Structures in Simulated Galaxies Using Unsupervised Machine Learning

Published: October 2019

Abstract
Galaxies host a wide array of internal stellar components, which need to be decomposed accurately in order to understand their formation and evolution. While significant progress has been made with recent integral-field spectroscopic surveys of nearby galaxies, much can be learned from analyzing the large sets of realistic galaxies now available through state-of-the-art hydrodynamical cosmological simulations. We present an unsupervised machine-learning algorithm, named auto-GMM, based on Gaussian mixture models, to isolate intrinsic structures in simulated galaxies based on their kinematic phase space. For each galaxy, the number of Gaussian components allowed by the data is determined through a modified Bayesian information criterion. We test our method by applying it to prototype galaxies selected from the cosmological simulation IllustrisTNG. Our method can effectively decompose most galactic structures. The intrinsic structures of simulated galaxies can be inferred statistically by non-human supervised identification of galaxy structures. We successfully identify four kinds of intrinsic structures: cold disks, warm disks, bulges, and halos. Our method fails for barred galaxies because of the complex kinematics of particles moving on bar orbits.
A Staggered Semi-analytic Method for Simulating Dust Grains Subject to Gas Drag
Authors: Fung Jeffrey , Muley Dhruv 
Published: October 2019

Abstract
Numerical simulations of dust–gas dynamics are one of the fundamental tools in astrophysical research, such as the study of star and planet formation. It is common to find tightly coupled dust and gas in astrophysical systems, which demands that any practical integration method be able to take time steps,

, much longer than the stopping time,

, due to drag. A number of methods have been developed to ensure stability in this stiff

regime, but there remains large room for improvement in terms of accuracy. In this paper, we describe an easy-to-implement method, the “staggered semi-analytic method” (SSA), and conduct numerical tests to compare it to other implicit and semi-analytic methods, including the second-order implicit method and the Verlet method. SSA makes use of a staggered step to better approximate the terminal velocity in the stiff regime. In applications to protoplanetary disks, this not only leads to orders of magnitude higher accuracy than the other methods, but also provides greater stability, making it possible to take time steps 100 times larger in some situations. SSA is also second-order accurate and symplectic when

. More generally, the robustness of SSA makes it applicable to linear dust–gas drag in virtually any context.
Une migration urgente et transitoire : la fuite des Juifs de France en Suisse au temps de la « solution finale »
Authors: Fivaz-Silbermann Ruth 
Published: October 2019

La migration, pour leur survie, des Juifs de France, de Hollande et de Belgique vers la Suisse débute en 1942, au moment où se déclenche la « solution finale » élaborée par les nazis. La Suisse a fermé ses frontières, mais accueille sous tolérance un certain nombre de fugitifs, tout en en refoulant d’autres. Un premier afflux vient de Hollande et de Belgique vers l’Arc jurassien, un second, bien plus important, de France non occupée, au moment des rafles de Vichy, vers Genève, le Léman et le Valais.
2001‑2010. L’invention des routes commerciales des transmigrants baloutches de Kandahar à Malaga
Authors: Tarrius Alain 
Published: October 2019

Les Baloutches irano-afghans, commerçants nomades, sont les transmigrants indispensables à la naissance d’une économie mondiale de l’entre pauvres (ou poor to poor) que développent, à partir des années 2000, les majors asiatiques de l’électronique, via Dubaï. À 65 000, ils inventent de larges routes, les territoires circulatoires, et initient des cosmopolitismes migratoires originaux, dans l’étape de la Mer Noire, avec d’autres migrants, Caucasiens et Balkaniques… et, en France, avec des jeunes des quartiers enclavés, lors des dernières étapes de leur transmigration. Les frontières nationales, locales et continentales sont redéfinies à l’occasion de leurs passages.
The TL1A-DR3 Axis Selectively Drives Effector Functions in Human MAIT Cells

Published: October 2019

Abstract
Mucosal-associated invariant T (MAIT) cells are semi-invariant T cells specifically recognizing riboflavin derivatives that are synthesized by many bacteria and fungi presented by MHC class I–related MR1 molecules. Accumulating evidence, however, indicates that MAIT cell functions are inducible by cytokine stimuli in the absence of TCR ligation, identifying MAIT cells as innate sentinels in inflammatory environments. In this study, we demonstrate that death receptor 3 (DR3), a member of the TNFR superfamily, is ex vivo expressed and predominantly upregulated on the surface of human MAIT cells by innate cytokine stimulation. In turn, the DR3 ligand TNF-like protein 1A (TL1A) licenses innate TNF-α production in the absence of cognate triggers, being sufficient to promote activation of primary endothelial cells in vitro. TL1A further amplifies synthesis of IFN-γ and granzyme B in the presence of otherwise weak innate stimuli and strongly augments polyfunctionality. Mechanistically, TL1A potentiates T-bet expression, early NF-κB, and late p38 MAP kinase phosphorylation, with the latter being indispensable for TNF-α production by MAIT cells. Of note, endogenous TL1A is also rapidly released from PBMC cultures in response to bacterial triggering, thereby equally augmenting Ag-specific MAIT cell effector functions. In summary, to our knowledge, we identify a new inflammatory mechanism in MAIT cells linking the DR3/TL1A axis with amplification of TCR-dependent and -independent effector functions, particularly inducing excessive innate TNF-α production. Given that both TL1A and TNF-α are abundantly present at sites of chronic inflammation, the contribution of MAIT cells in such scenarios needs to be determined.
Copper/reduced graphene oxide nanocomposite for high performance photocatalytic methylene blue dye degradation
Authors: Aragaw Belete Asefa , Dagnaw Atsedemariam 
Published: October 2019

Copper nanoparticles deposited on reduced graphene oxide (RGO) have been investigated for various applications. In many of these reports RGO is used as a support and electron collector and not as a light absorber. However, Cu nanoparticle decorated over the surface of semiconducting RGO as a light absorber has not been investigated for its photocatalytic organic dye degradation activity. Here, we deposited Cu nanoparticle on RGO sheet by insitu photoreduction method. The Cu/RGO nanocomposite photocatalyst material is characterized by UV-Visible spectroscopy, FT-IR and X-ray powder diffraction and its photodegradation activity towards model organic dye was investigated. Based on our results, it was found that the photocatalytic degradation efficiency of GO, RGO and Cu/RGO nanocomposites were 63%, 68% and 94%, respectively under light irradiation at pH~7 in 50 min. The high photocatalytic performance of Cu/RGO nanocomposite is due to the catalytic effect of Cu. The Cu nanoparticle is a good photoelectron acceptor that traps the photoelectron and reduces the recombination rate of photoelectron-hole pairs. We believe that our finding would be widely applicable to the graphene oxide based composites with metal or metal oxide nanoparticles to develop a cost effective technique for environmental protection.
How waviness in the circulation changes surface ozone: a viewpoint using local finite-amplitude wave activity
Authors: Sun Wenxiu , Hess Peter , Chen Gang , Tilmes Simone 
Published: October 2019

Abstract. Local finite-amplitude wave activity (LWA) measures the waviness of the local flow. In this work we relate the anticyclonic part of LWA, AWA (anticyclonic wave activity), to surface ozone in summertime over the US on interannual to decadal timescales. Interannual covariance between AWA diagnosed from the European Centre for Medium-Range Weather Forecast Era-Interim reanalysis and ozone measured at EPA Clean Air Status and Trends Network (CASTNET) stations is analyzed using maximum covariance analysis (MCA). The first two modes in the MCA analysis explain 84 % of the covariance between the AWA and MDA8 (maximum daily 8 h average ozone), explaining 29 % and 14 % of the MDA8 ozone variance, respectively. Over most of the US we find a significant relationship between ozone at most locations and AWA over the analysis domain (24–53∘ N and 130–65∘ W) using a linear regression model. This relationship is diagnosed (i) using reanalysis meteorology and measured ozone from CASTNET, or (ii) using meteorology and ozone simulated by the Community Atmospheric Model version 4 with chemistry (CAM4-chem) within the Community Earth System Model (CESM1). Using the linear regression model we find that meteorological biases in AWA in CAM4-chem, as compared to the reanalysis meteorology, induce ozone changes between −4 and +8 ppb in CAM4-chem. Future changes (ca. 2100) in AWA are diagnosed in different climate change simulations in CAM4-chem, simulations which differ in their initial conditions and in one case differ in their reactive species emissions. All future simulations have enhanced AWA over the US, with the maximum enhancement in the southwest. As diagnosed using the linear regression model, the future change in AWA is predicted to cause a corresponding change in ozone ranging between −6 and 6 ppb. The location of this change depends on subtle features of the change in AWA. In a number of locations this change is consistent with the magnitude and the sign of the overall simulated future ozone change.
Tipping the ENSO into a permanent El Niño can trigger state transitions in global terrestrial ecosystems
Authors: Duque-Villegas Mateo , Salazar Juan Fernando , Rendón Angela Maria 
Published: October 2019

Abstract. Some large-scale components of the Earth's climate system
have been identified as policy-relevant “tipping elements”, meaning that
anthropogenic forcing and perturbations may push them across a tipping point
threshold, with potential global scale impact on ecosystems and concomitant
environmental and social phenomena. A pronounced change in the amplitude
and/or frequency of the El Niño–Southern Oscillation (ENSO) is among
such tipping elements. Here, we use the Planet Simulator (PlaSim), an Earth
system model of intermediate complexity, to investigate the potential impact
on global climate and terrestrial ecosystems of shifting the current dynamics
of the ENSO into a permanent El Niño. When forced with sea surface
temperature (SST) derived from observations, the PlaSim model yields a
realistic representation of large-scale climatological patterns, including
realistic estimates of the global energy and water balances, and gross
primary productivity (GPP). In a permanent El Niño state, we found
significant differences in the global distribution of water and energy
fluxes, and associated impacts on GPP, indicating that vegetation production
decreases in the tropics, whereas it increases in temperate regions. We
identify regions in which these El Niño-induced changes are consistent
with potential state transitions in global terrestrial ecosystems, including
potential greening of western North America, dieback of the Amazon
rainforest, and further aridification of south-eastern Africa and Australia.

Published: October 2019

Abstract. Despite the importance of glacial lake development in ice dynamics and glacier thinning, in situ and satellite-based measurements from lake-terminating glaciers are sparse in the Bhutanese Himalaya, where a number of proglacial lakes exist. We acquired in situ and satellite-based observations across lake- and land-terminating debris-covered glaciers in the Lunana region, Bhutanese Himalaya. A repeated differential global positioning system survey reveals that thickness change of the debris-covered ablation area of the lake-terminating Lugge Glacier (-4.67±0.07 m a−1) is more than 3 times more negative than that of the land-terminating Thorthormi Glacier (-1.40±0.07 m a−1) for the 2004–2011 period. The surface flow velocities decrease down-glacier along Thorthormi Glacier, whereas they increase from the upper part of the ablation area to the terminus of Lugge Glacier. Numerical experiments using a two-dimensional ice flow model demonstrate that the rapid thinning of Lugge Glacier is driven by both a negative surface mass balance and dynamically induced ice thinning. However, the thinning of Thorthormi Glacier is minimised by a longitudinally compressive flow regime. Multiple supraglacial ponds on Thorthormi Glacier have been expanding since 2000 and have merged into a single proglacial lake, with the glacier terminus detaching from its terminal moraine in 2011. Numerical experiments suggest that the thinning of Thorthormi Glacier will accelerate with continued proglacial lake development.
Improving mesoscale wind speed forecasts using lidar-based observation nudging for airborne wind energy systems
Authors: Sommerfeld Markus , Dörenkämper Martin , Steinfeld Gerald , Crawford Curran 
Published: October 2019

Abstract. Airborne wind energy systems (AWESs) aim to operate at altitudes above conventional wind turbines where reliable high-resolution wind data are scarce. Wind light detection and ranging (lidar) measurements and mesoscale models both have their advantages and disadvantages when assessing the wind resource at such heights. This study investigates whether assimilating measurements into the mesoscale Weather Research and Forecasting (WRF) model using observation nudging generates a more accurate, complete data set. The impact of continuous observation nudging at multiple altitudes on simulated wind conditions is compared to an unnudged reference run and to the lidar measurements themselves. We compare the impact on wind speed and direction for individual days, average diurnal variability and long-term statistics. Finally, wind speed data are used to estimate the optimal traction power and operating altitudes of AWES. Observation nudging improves the WRF accuracy at the measurement location. Close to the surface the impact of nudging is limited as effects of the air–surface interaction dominate but becomes more prominent at mid-altitudes and decreases towards high altitudes. The wind speed frequency distribution shows a multi-modality caused by changing atmospheric stability conditions. Therefore, wind speed profiles are categorized into various stability conditions. Based on a simplified AWES model, the most probable optimal altitude is between 200 and 600 m. This wide range of heights emphasizes the benefit of such systems to dynamically adjust their operating altitude.
A Review of Inpatient Opioid Consumption and Discharge Prescription Patterns After Orthopaedic Procedures
Authors: Grace Trevor R. , Choo Kevin J. , Patterson Joseph T. , Khanna Krishn , Feeley Brian T. , Zhang Alan L. 
Published: October 2019

Introduction:
Tailoring opioid prescriptions to inpatient use after orthopaedic procedures may effectively control pain while limiting overprescription but may not be common in the current orthopaedic practice.

Methods:
A retrospective review identified opioid-naïve patients admitted after any orthopaedic procedure. Daily and total prescription quantities as well as patient-specific factors were collected. The total opioids used the day before discharge was compared with the total opioids prescribed for the day after discharge. Refill rates were then compared between patients whose daily discharge prescription regimen far exceeded or approximated their predischarge opioid consumption.

Results:
Six hundred thirteen patients were included (ages 18 to 95 years). The total opioids prescribed for the 24 hours after discharge significantly exceeded the opioids consumed the 24 hours before discharge for each orthopaedic subspecialty. The excessive-prescription group (409 patients) received greater daily opioid (120 oral morphine equivalents [OMEs] versus 60 OMEs; P < 0.01) and total opioid (750 OMEs versus 512.5 OMEs; P < 0.01) at discharge but was more likely to refill their opioid prescription within 30 days of discharge (27.6% versus 20.1%; P = 0.043).

Discussion:
Opioid regimens prescribed after an orthopaedic surgery frequently exceed inpatient opioid use. Opioid regimens that approximate inpatient use may help curb overprescription and are not associated with higher refill rates compared with more excessive prescriptions.

Level of Evidence:
Level III, Retrospective Cohort Study
