Authors: Yulianto E , Abdullah F , Novrizal N , Riyanto A 
Published: April 2020

Abstract
Pseudo three dimensional (3D) seismic has been carried out to real seismic dataset using biharmonic spline interpolation. The dataset contains 11 two dimensional (2D) seismic lines with two-millisecond sampling rates and 2000 millisecond record length. Biharmonic spline interpolation was performed for each time sample using the gridding interval of 25 x 25 meter. The resulted interpolation for each time sample was combined to generate three-dimension matrix that called as pseudo-3D seismic. The results of pseudo-3D seismic data clearly showed the structural geological features, compared to 2D seismic data. The result can minimize the uncertainty of the subsurface interpretation and reduce the exploration risk.

Authors: Firdaus F , Pin T G , Supriatna  
Published: April 2020

Abstract
Estuaries are coastal ecosystems with highest productivities owing to the presence phytoplankton in water. Phytoplankton plays a key role in water as a primer for productivity, primarily by producing both organic and inorganic substances. In 2010, the construction of Pelabuhanratu Coal Power Plant (PLTU) along the banks of the Cimandiri estuary got completed and PLTU started operating. This study aims to analyze the changes and relation between the water’s physical characteristics and the phytoplankton distribution before and after the construction of the Pelabuhanratu PLTU. Variables used total suspended solids, salinity, sea surface temperature, currents, and chlorophyll-a concentration to describe the water’s physical characteristics as well as indicators for the presence of phytoplankton. These methods were combined with remote sensing data and validated by in-situ results. The results indicate that the amount of phytoplankton before the construction of PLTU was significantly higher in comparison with that after the completion of PLTU. Moreover, phytoplankton concentration is directly proportional to the total suspended solids and sea surface temperature but is inversely proportional to salinity, and has no effect on ocean currents.

Published: April 2020

Abstract
Although climate change mitigation regarding mangrove forest management has been given significant international attention during the past decade, there are no sufficiently reliable data to quantify the availability of carbon stock in mangrove forests. The mangrove forest in the Bali Province is divided into three habitat types, namely an open bay located in the West Bali National Park, a semi-closed bay located in Tahura Ngurah Rai and a small island in the protected forest of Nusa Lembongan. The objective of this study is to analyse the relationship between carbon stock characteristics of mangrove forests with the different types and morphologies of mangrove forest habitats. Biomass calculations were carried out by using the allometric formula. However, the similar allometric equations produced varying accuracies at different locations. Results revealed that the mangrove forest carbon stock for the semi-closed bay habitat has the highest estimation value of 51.35 tons/ha and a positive relationship pattern of 60 %. On the contrary, the lowest carbon stock value is the open bay beach with a value 26.28 tons/ha and positive relationship pattern of 48 %. This study reveals that each type of mangrove forest habitat has its own living ecosystem characteristics that affect the carbon stock value.

Published: April 2020

Abstract
Rice is a basic need for most Indonesians. Subang Regency is one of the food districts in West Java with high paddy rice production. Fluctuation in the value of paddy rice production over the past five years makes production conditions uncertain and difficult to predict. Monitoring the condition of paddy rice fields over a short period of time would improve crop size prediction. This study aims to explain the paddy rice phenology using Sentinel 2-A imagery with NDVI (Normalized Difference Vegetation Index) algorithm in Subang Regency. The benefit of this study is to monitor the paddy rice phenology using remote sensing technology. Greenness values were recorded from Sentinel 2-A temporal 10 daily images with NDVI algorithm. Greenness values will be analysed descriptively according to CCTV recording on paddy rice fields. Based on the greenness value, NDVI can determine the beginning of the planting period and the end of the paddy rice planting period. The results show that Sentinel 2-A imagery can monitor the paddy rice phenology by measuring the value of NDVI vegetation index. The development of remote sensing technology can be used for estimating paddy rice phenology over short periods of time.

Abstract
Socio-ecological landscape is formed by human activities in the physical environment shows customary, familial, collectivity and capital structure for sustainability. There are 3 types of socio-ecological landscape based on altitude: local wisdom-based agricultural landscapes at altitude 0-100 MASL, traditional ecological knowledge-based agroforestry landscapes at altitude 101-600 MASL, and customary law-based forest landscapes at altitude 601-1000 MASL. This study documents sacred places protected by indigenous community, customary law relevancies, and the perception of forest tenure. Quantitative and qualitative methods result encroachment often found in agroforestry landscapes (altitudes of 100-600 MASL) where forest garden road wage mobilization from settlement to forest area and there is a dominance of private-owned garden within state forest areas.
Multicomponent Antifriction Composite Based on Extrudable Matrix “UHMWPE - HDPE-g-VTMS - PP” for Additive Manufacturing

Published: April 2020

Abstract
Tribomechanical properties of antifriction composites based on the extrudable matrix “UHMWPE + 17 wt. % HDPE-g-VTMS + 12 wt. % PP” with chopped fiberglass formed by three methods: Hot Pressing of Powders (HPP), Hot Pressing of Granules (HPG) and Fused Deposition Modeling (FDM) was studied. It has been found that a composite fabricated by the FDM method possesses the highest strength properties (elastic modulus, yield strength and tensile strength). It is shown that tribological properties (friction coefficient, volumetric wear) of composites fabricated by the three methods are close to each other that is related to impact of the reinforcing filler (fiberglass). The latter takes on compressive and shearing loads during tribo-loading and improves wear resistance of the composite. The studied multicomponent UHMWPE based composite is recommended for use as a feedstock for the manufacturing antifriction products by additive manufacturing.
Size dependence of the dislocation segment vibration spectrum for various types of dislocations
Authors: Bataronov I L , Dezhin V V 
Published: April 2020

Abstract
The vibration spectra of the edge, mixed and screw dislocations, depending on the dislocation segment length, are considered. The value of Poisson’s ratio 1/3 is assumed. The normalized values of the eigenfrequencies and damping coefficients for different frequency numbers by equating the inverse matrix of dislocation oscillators generalized susceptibilities to zero were found. It is seen from the dependences obtained that in the case of a screw dislocation, the transformation of the dislocation oscillators generalized susceptibility poles occurs. For edge and mixed dislocations the transformation of the poles was not observed. This agrees with the results of the vibration spectrum orientation dependence study. The authors suggest that these differences are due to the presence of a screw dislocation quasilocal vibration branches.

Abstract
Nickel oxide (NiO) film receives attention from the field of optoelectronics due to its wide band gap and high transparency. By using a sparking method, the deposition of the NiO film is facile and unique. However, the NiO film made by the sparking method indicates a porous surface with an agglomeration of its particles. In order to reduce the porousness of the NiO film, the assistance of a permanent magnet in the sparking apparatus is presented. Here, we report the investigation of the NiO film and the p-NiO/n-ZnO heterojunction deposited by the sparking method under a magnetic field. Our results demonstrate that the porosity of the NiO film was reduced by increasing the magnitude of a magnetic field from 0 mT to 375 mT. Furthermore, the crystallinity and the electrical properties of the NiO film are improved by the influent of a magnetic field. For heterojunction, the best device shows the rectification ratio of 95 and the ideality factor of 4.92. This work provides an alternative method for the deposition of the NiO film with promising applications in optoelectronic devices.
Effect of ‘water-in-salt’ electrolytes in the electrochemical hydrogen evolution reaction of carbon nanotubes
Authors: Guha Anku , Narayanan Tharangattu N 
Published: April 2020

Abstract
Super-concentrated electrolytes based electrochemistry is an emerging trend in electrochemical processes (Borodin et al 2020 Joule
4 69–100), where unprecedented properties were reported recently. Such an ‘electrolyte engineered approach’ can find applicabilities in modern batteries and catalysis. Here we report the use of such high concentration lithium ions (Li+) containing electrolytes for enhancing the electrocatalytic hydrogen evolution (HER) performance of carbon nanotubes (CNTs), contrary to that observed with platinum. Different types of CNTs, namely metallic multi-wall (MWCNTs) and semiconducting single wall (SWCNTs), are tested towards the Li+ effect in the HER performance and similar trends are obtained. Further, different lithium salts having counter ions such as TFSI−, OTf−, ClO4
−, Cl−, and OH− are also tested to verify the mechanism, and the role of Li+ in the HER augmentation of CNTs is established. The studies are conducted in different electrolytes having a range of pH values too (0–13), and the cation induced CNT’s HER enhancement is generalized. This study shows that even the sluggish HER kinetics of CNTs in alkaline medium can be augmented by such an electrolyte engineering approach where catalyst’s surface do not undergo any permanent modification. Further, such electrodes are found to be highly stable towards the long term HER performance.
Repairing Damage: The Slave Ship Marcelin and the Haiti Trade in the Age of Abolition
Authors: Lewis Mary Dewhurst 
Published: April 2020

Abstract
Between 1814 and 1831, French slave traders trafficked approximately 200,000 individuals. Among those, a small but still surprising number stopped over in Haiti on their return voyage after selling captives elsewhere in the Americas. Using the case of the brigantine the Marcelin as its prime example, this article shows how legitimate commodity trading with Haiti served as a cover for illicit French slaving in the era of slave-trade abolition. The article situates the Marcelin within a “second slave trade,” which emerged as European countries abolished the transatlantic trade on paper but continued it in practice. Because the second slave trade was illegal, it left a very limited historical trace. This article reconstructs its contours from fragmentary archival evidence, while arguing that, ultimately, the archive itself does violence to the history of the nineteenth-century slave trade.

Abstract
Enteric fever remains a major cause of morbidity in developing countries with poor sanitation conditions that enable fecal contamination of water distribution systems. Historical evidence has shown that contamination of water systems used for household consumption or agriculture are key transmission routes for Salmonella Typhi and Salmonella Paratyphi A. The World Health Organization now recommends that typhoid conjugate vaccines (TCV) be used in settings with high typhoid incidence; consequently, governments face a challenge regarding how to prioritize typhoid against other emerging diseases. A key issue is the lack of typhoid burden data in many low- and middle-income countries where TCV could be deployed. Here we present an argument for utilizing environmental sampling for the surveillance of enteric fever organisms to provide data on community-level typhoid risk. Such an approach could complement traditional blood culture-based surveillance or even replace it in settings where population-based clinical surveillance is not feasible. We review historical studies characterizing the transmission of enteric fever organisms through sewage and water, discuss recent advances in the molecular detection of typhoidal Salmonella in the environment, and outline challenges and knowledge gaps that need to be addressed to establish environmental sampling as a tool for generating actionable data that can inform public health responses to enteric fever.
A tale of two countries: how decentralized organization and long-term investment build resilient healthcare systems
Authors: Kirchhof Paulus 
Published: April 2020

Abstract
Healthcare systems are faced with unique challenges during the ongoing Covid-19 pandemic. This viewpoint compares the response to the Covid-19 pandemic in the UK and in Germany. Despite being two large European countries of comparable size with good healthcare systems and similar patterns of exposure to Covid-19, Covid-19 related deaths in the UK currently far outnumber those in Germany. This has several reasons, but two explanations stick out: 1. lower long-term investment into healthcare in the UK rendered the NHS more vulnerable to Covid-19; 2. the existence of a well-governed decentralised and partially redundant organisation of healthcare increased resilience in Germany’ s healthcare systems, enhancing the ability to adapt in response to unexpected challenges to healthcare. The response to the current pandemic also illustrates the power and the necessity to learn from each other through transparent communication of successes and mistakes.
Cubature rules from Hall–Littlewood polynomials
Authors: van Diejen J F , Emsiz E 
Published: April 2020

AbstractDiscrete orthogonality relations for Hall–Littlewood polynomials are employed so as to derive cubature rules for the integration of homogeneous symmetric functions with respect to the density of the circular unitary ensemble (which originates from the Haar measure on the special unitary group $SU(n;\mathbb{C})$). By passing to Macdonald’s hyperoctahedral Hall–Littlewood polynomials, we moreover find analogous cubature rules for the integration with respect to the density of the circular quaternion ensemble (which originates in turn from the Haar measure on the compact symplectic group $Sp (n;\mathbb{H})$). The cubature formulas under consideration are exact for a class of rational symmetric functions with simple poles supported on a prescribed complex hyperplane arrangement. In the planar situations (corresponding to $SU(3;\mathbb{C})$ and $Sp (2;\mathbb{H})$), a determinantal expression for the Christoffel weights enables us to write down compact cubature rules for the integration over the equilateral triangle and the isosceles right triangle, respectively.

Abstract
Currently, coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been reported in almost all countries globally. No effective therapy has been documented for COVID-19, and the role of convalescent plasma therapy is unknown. In the current study, 6 patients with COVID-19 and respiratory failure received convalescent plasma a median of 21.5 days after viral shedding was first detected, all tested negative for SARS-CoV-2 RNA within 3 days after infusion, and 5 eventually died. In conclusion, convalescent plasma treatment can end SARS-CoV-2 shedding but cannot reduce the mortality rate in critically ill patients with end-stage COVID-19, and treatment should be initiated earlier.

Abstract
Chronic active antibody-mediated rejection (CAAMR) is a particular problem in kidney transplantation (KTx), and ~25% of grafts are lost by CAAMR. Further, the pathogenesis remains unclear, and there is no effective cure or marker. We previously found that a hyper NFκB-activating mechanism in non-immune cells, called the IL-6 amplifier, is induced by the co-activation of NFκB and STAT3, and that this activation can develop various chronic inflammatory diseases. Here, we show that synaptotagmin-17 (SYT17) is increased in an exosomal fraction of the urine from CAAMR patients, and that this increase is associated with activation of the IL-6 amplifier. Immunohistochemistry showed that SYT17 protein expression was increased in renal tubule cells of the CAAMR group. While SYT17 protein was not detectable in whole-urine samples by western blotting, urinary exosomal SYT17 levels were significantly elevated in the CAAMR group compared to three other histology groups (normal, interstitial fibrosis and tubular atrophy, and calcineurin inhibitors toxicity) after KTx. On the other hand, current clinical laboratory data could not differentiate the CAAMR group from these groups. These data suggest that urinary exosomal SYT17 is a potential diagnostic marker for CAAMR.
Preferences and Civil War in Northern Uganda: Post-Traumatic Growth Reconsidered

Published: April 2020

Abstract
We exploit the largely exogenous character of abduction and displacement in northern Uganda during the recent civil war to estimate the effects of each on experimental measures of risk tolerance, altruism, trust and trustworthiness, as well as a survey measure of patience. Our analysis reveals the limitations of the ‘post-traumatic growth’ hypothesis. In most cases preferences are unaffected by these traumas and in the one domain in which we identify a significant effect, it is contrary to the hypothesis—people who were both abducted and displaced are 21 percentage points less likely to take a risk.

Published: April 2020

Abstract

Candida albicans and Candida glabrata are frequently coisolated from the oral cavity in immunosuppressive or immunocompromised individuals. Their relationship is usually defined as competition as C. glabrata can inhibit growth of C. albicans in cohabitation. In this study, eight C. albicans isolates as well as two C. glabrata strains were used to investigate the effects of culture medium (Roswell Park Memorial Institute [RPMI]-1640, YPD, YND), incubation time (24 h, 48 h, 72 h, 96 h), initial inoculum (C. glabrata: C. albicans = 2:1, 1:1, 1:2), and medium state (static and dynamic states) on viable cell enumeration and relative abundance in both Candida SB and MB. The results showed that in most cases, C. glabrata and C. albicans SB and MB flourished in RPMI-1640 at 24 h under dynamic state compared with other conditions. Except YPD medium, there were high proportions of preponderance of C. albicans over C. glabrata in MB compared with SB. High initial inoculum promoted corresponding Candida number in both SB and MB and its abundance in MB relative to SB. This study revealed an impact of several environmental conditions on the formation of C. albicans and C. glabrata SB and MB and their abundance in MB in comparison with SB, deepening our understanding of both Candida interaction and their resistance mechanism in MB.

Lay Summary
This study described the effects of diverse experimental conditions on the numbers of Candida albicans and Candida glabrata single biofilms and mixed biofilms and their abundance.
