Abstract
We analyzed the distribution of Purse seine fishing vessels using fishing lamps derived from the Day/Night Band Visible Infrared Imaging Radiometer Suite (DNB-VIIRS) sensor and Vessels Monitoring System (VMS) platform in the Java Sea. The data of fishing vessel distribution derived the DNB-VIIRS sensor and VMS platform was provided by NOAA Center for Environment Information and Global Fishing Watch respectively. The intensity of lights during the fishing operation was measured by a lux meter. The fishing vessel types that used light during fishing operations were small (< 15 units lamps) and large vessels (>15-unit lamps). The intensity of light in the big vessels (> 2,000 Lux) was higher than the small vessels (< 2,000 Lux). The average number of fishing vessels operating during the Southeast monsoon were more than those of the Northwest monsoon. The distribution of fishing vessels derived from the DNB-VIIRS sensor has a similar pattern with the VMS platform. Generally, the fishing vessels are concentrated along the southern coast of Borneo but in the Northwest monsoon shift towards the northwest of Java approaching the island of Sumatra.

Abstract
Pandeglang District becomes a concern because one of the locations had an impact on the Tsunami on December 22, 2018. Its position in the western waters and directly facing the Anak Krakatau Volcano is very potentially vulnerable. The Tsunami triggered by the volcanic activity of Anak Krakatau Volcano, mountain avalanche material. Evaluation regarding coastal land affected is also needed to anticipate future disasters. The study of the coastal areas affected by extraordinary events, such as the Tsunami, was carried out by stakeholders in evaluating coastal land to be more responsive to disasters. Three sub-districts with different morphology selected as samples of the affected areas, Labuan, Sumur, and Panimbang. We used highresolution Sentinel 2.0 images and Elevation Model Data (SRTM DEM) with unsupervised classification method to perform analysis of the area affected by Tsunami condition on coastal features. The results showed that the area affected especially the low land, as open land area at Labuan Sub-district was 189,298 Ha, Sumur Sub-district, 144,837 Ha, and Panimbang Sub-district was 282.852 Ha. Varied inundation range 50 - 200 meters from the coastline. The elevation of the three sub-districts shows vulnerable areas with an elevation of <2.5 m to 0.5 m above sea level.

Abstract
Wetlands in the Andean region have been altered and have been lost as a result of the agricultural frontier expansion and human activities. The disturbance of the paramo ecosystem by the destruction or alteration of the wetlands modifies the load and endowment of water to the hydrological systems, which provide water to main cities in the highlands. Therefore, the present work focuses on setting up the framework for wetland monitoring in the Andean paramo region using Unmanned Aerial Vehicles (UAVs). For this aim, the study was based on a mission profile using a fixed wing UAV incorporated with a RGB camera in one of the most documented wetlands in the Ecuadorian paramo region, Pugllohuma wetland. Furthermore, to assess the saturation of the wetland, field testing data has been collected to set the range values of saturation for the monitoring system. In the same way, a review regarding multispectral imagery for the assessment of water and vegetation indices is explored and highlighted for future work. This work is a first stage in the monitoring process and hence it aims to set a baseline study for the implementation of a more detailed methodology.
Computer aided design of an aquaculture equipment for the durable development of the marine ecosystem’s biodiversity
Authors: Ene A G , Mihai C 
Published: January 2020

Abstract
Modern aquaculture represents a major innovation in the field of fish production and has been the fastest growing food production sector, reaching an average worldwide growth rate of 6-8% per year. Aquaculture offers important possibilities and generates significant challenges, especially regarding the ecological sustainability of the production, as well as the quality and safety of the products. The epibiont encompass all marine invertebrates that, during the juvenile stages, attach themselves to hard natural supports (rock, submerged rocky platforms) and carry out their entire life cycle [1]. Through the “Strategic guidelines for the sustainable development of aquaculture in the EU”, the European Commission emphasizes the strategic nature of aquaculture production (as well as other productions in the primary sector), so that it can respond to future challenges related to food, natural resources and territories. In order to establish the design parameters of the aquaculture equipment intended for the expansion in space of the group of filtering organisms whose food value and ecological role in maintaining adequate physical, chemical and biological qualities of the seawater are well known, a specialized software was used in order to enable the optimal design and numerical simulation of the conditions in which the equipment operates.

Abstract
Aquaponics is not a new technology including a wide variety of systems, but the interest has grown rapidly in recent years, especially in developing countries. Each system has different types and levels of costs and interest. Aquaponics can be implemented using low-cost materials making it more attractive farmers to diversify their incomes. This article examined the profitability of applied aquaponics in thoroughly reused, recycle local materials and the local species. Three sources of data were considered for the study: (1) commercial local species farms, (2) applied aquaponics farms and (3) published research. The first analysis compares the economics of local farms, traditional aquaponics and applied aquaponics systems under similar operations. Results suggest that the traditional aquaponics system requires higher investment and operating cost compared with the applied aquaponics system and local farms. The second analysis constructed on the aquaponics production of fish and plants as well as the returns. The study found that at the small scale of 1-year operation, applied aquaponics is the most profitable model ($1991.34) at 36 percentage of interest. It is more advantage to develop the economic, social by building environmental sustainability of agriculture to maximize food production through applied aquaponics. The economic efficiency of applied aquaponics in using multiple use of resources, primarily water and nutrients, and recycle certain infrastructural, management and labor costs will keep the aquaponics lasting and expanding to social life.
Comparison performance of machine learning and geostatistical methods for the interpolation of monthly air temperature over Costa Rica
Authors: Méndez M , Calvo-Valverde L.A 
Published: January 2020

Abstract
The performance of three machine learning (ML) methods; cubist regression (CR), random forest (RF) and generalized additive model using splines (GAM) in generating monthly air temperature grids over Costa Rica was evaluated against two heavily used geostatistical methods; ordinary kriging (OK) and kriging with external drift (KED). The skill of the interpolation methods was evaluated using a 10-fold cross-validation technique; selecting the root-mean square error (RMSE), the mean absolute error (MAE) and the Pearson correlation-coefficient (R) as agreement metrics. To this purpose, data from an irregularly-distributed observational-network comprised by 73 weather-stations were selected for the period 1950-1987. Several spatial fields derived from a high-resolution digital elevation model (DEM) were tested as covariants. Results from the 10-fold cross-validation test show that CR yielded the best individual performance followed by KED, whereas GAM performed worst. Elevation on the other hand, was the only covariant ultimately incorporated in the interpolation process, since the remaining spatial fields exhibited poor correlation with temperature or resulted in data redundancy. While the quantitative and qualitative evaluation of CR and KED can be said to be comparable, CR is considered the best approach since the method is unaffected by assumptions on data normality and homoscedasticity.

Abstract
Over the past century, the field of epidemiology has evolved and adapted to changing public health needs. Challenges include newly emerging public health concerns across broad and diverse content areas, new methods, and vast data sources. We recognize the need to engage and educate the next generation of epidemiologists and prepare them to tackle these issues of the 21st century. In this commentary, we suggest a skeleton framework upon which departments of epidemiology should build their curriculum. We propose domains that include applied epidemiology, biological and social determinants of health, communication, creativity and ability to collaborate and lead, statistical methods, and study design. We believe all students should gain skills across these domains to tackle the challenges posed to us. The aim is to train smart thinkers, not technicians, to embrace challenges and move the expanding field of epidemiology forward.
The Target of Exuberant Projections in Development
Authors: Innocenti Giorgio M 
Published: January 2020

ABSTRACT
In addition to neuronal death and elimination of synapses, the production of transient, exuberant axons, and axonal branches is a general phenomenon in development across species and systems. To understand what drives the decision of which axons are maintained and which are eliminated, it is important to monitor the interaction of juvenile axons at their target. As old and more recent work show, unlike what is claimed by Ribeiro Gomez et al. (2019), in the cerebral cortex, both classes of axons branch in the white matter near the target; axons destined to be maintained massively invade the gray matter where they develop terminal arbors and synapses. Axons destined to elimination remain in the white matter although a few transient, exploratory branches can enter the cortex. Axonal behavior and fate seem dictated by positional information probably conveyed by thalamic afferents and activity. Unlike what is suggested by Ribeiro Gomez et al. (2019), axonal selection should not be confused with synaptic reduction, which is a later event with minor or no impact on the topography of the connection.
Immediate dilation in esophageal food impaction is safe and effective but performed infrequently: observations from a large Midwest US cohort

Published: January 2020

Summary
This study aimed to determine the rate and safety of immediate esophageal dilation for esophageal food bolus impaction (EFBI) and evaluate its impact on early recurrence (i.e. prior to interval esophageal dilation) from a large Midwest US cohort. We also report practice patterns among community and academic gastroenterologists practicing in similar settings. We identified adult patients with a primary discharge diagnosis for EFBI from January 2012 to June 2018 using our institutional database. Pregnant patients, incarcerated patients, and patients with esophageal neoplasm were excluded. The primary outcome measured was rate of complications with immediate esophageal dilation after disimpaction of EFBI. Secondary outcomes were recurrence of food bolus impaction prior to scheduled interval endoscopy for dilation, practice patterns between academic and private gastroenterologists, and adherence to follow-up endoscopy. Two-hundred and fifty-six patients met our inclusion criteria. Esophageal dilation was performed in 46 patients (18%) at the time of disimpaction. A total of 45 gastroenterologists performed endoscopies for EFBI in our cohort. Twenty-five (62%) did not perform immediate esophageal dilation, and only 5 (11%) performed immediate dilation on greater than 50% of cases. Academic gastroenterologists performed disimpaction of EFBI for 102 patients, immediate dilation as performed in 20 patients and interval dilation was recommended in 82 patients. Of these 82, only 31 patients (38%) did not return for interval dilation. Four patients who did not undergo immediate dilation, presented with recurrent EFBI prior to interval dilation, within 3 months. None of the patients had complications. Complications with immediate esophageal dilation after disimpaction of EFBI are infrequent but are rarely performed. Failure of immediate dilation increases the risk of EFBI recurrence. Given poor patient adherence to interval dilation, immediate dilation is recommended.
Detecting repeating aftershocks in the Three Gorges Reservoir region, Central China

Published: January 2020

SUMMARYSlippage on a deep fault, which cannot be directly measured, can be inferred from repeating earthquakes. Here, we use a matched filter technique (MFT) to detect missing earthquakes near the Xiannvshan fault in the Three Gorges Reservoir region of Central China. We detected 13 repeating aftershock sequences (RASs) containing 107 events after a Ms 4.4 local earthquake that occurred on 26 March 2014. The RASs occurred in the vicinity of the Ms 4.4 main shock hypocentre and were concentrated within a depth range of 4–7 km. The short-term slip rates estimated from these RASs varied from ∼0.001 to 0.31 mm d–1. The slip rates of the RASs followed an approximately logarithmic decay with RAS duration, suggesting that the deep Xiannvshan fault behaviour tended to follow the logarithmic velocity-strengthening friction law. Relatively high-stress RAS events seemed to influence the occurrence of other RAS events whereas we found no evidence that high-stress nearby events, including a Ms 4.6 local earthquake that occurred on 29 March 2014, triggered the RAS events. We suggest that the fault stress change caused by the Ms 4.4 main shock played a role in triggering the RAS events. Our results demonstrate that the MFT can effectively help identify repeating aftershocks, which could help decipher fault zone rheology.
Observer-based output feedback control design for a coupled system of fractional ordinary and reaction–diffusion equations
Authors: Amiri Shadi , Keyanpour Mohammad , Asaraii Asadollah 
Published: January 2020

Abstract
In this paper, we investigate the stabilization problem of a cascade of a fractional ordinary differential equation (FODE) and a fractional reaction–diffusion (FRD) equation where the interconnections are of Neumann type. We exploit the partial differential equation backstepping method for designing a controller, which guarantees the Mittag–Leffler stability of the FODE-FRD cascade. Moreover, we propose an observer that is Mittag–Leffler convergent. Also, we propose an output feedback boundary controller, and we prove that the closed-loop FODE-FRD system is Mittag–Leffler stable in the sense of the corresponding norm. Finally, numerical simulations are presented to verify the results.
Buryak–Okounkov Formula for the n-Point Function and a New Proof of the Witten Conjecture

Published: January 2020

Abstract
We identify the formulas of Buryak and Okounkov for the $n$-point functions of the intersection numbers of psi-classes on the moduli spaces of curves. This allows us to combine the earlier known results and this one into a principally new proof of the famous Witten conjecture/Kontsevich theorem, where the link between the intersection theory of the moduli spaces and integrable systems is established via the geometry of double ramification cycles.

Abstract

Background
Mutations in the genes inhA, katG, and rpoB confer resistance to anti-tuberculosis (TB) drugs isoniazid and rifampin. We questioned whether specific mutations in these genes were associated with different clinical and microbiological characteristics.

Methods
In a multicountry prospective cohort study of multidrug-resistant TB, we identified inhA, katG, and rpoB mutations in sputum isolates using the Hain MTBDRplus line probe assay. For specific mutations, we performed bivariate analysis to determine relative risk of baseline or acquired resistance to other TB drugs. We compared time to sputum culture conversion (TSCC) using Kaplan-Meier curves and stratified Cox regression.

Results
In total, 447 participants enrolled from January 2005 to December 2008 from 7 countries were included. Relative to rpoB S531L, isolates with rpoB D516V had less cross-resistance to rifabutin, increased baseline resistance to other drugs, and increased acquired fluoroquinolone resistance. Relative to mutation of katG only, mutation of inhA promoter and katG was associated with baseline extensively drug resistant (XDR) TB, increased acquired fluoroquinolone resistance, and slower TSCC (125.5 vs 89.0 days).

Conclusions
Specific mutations in inhA and katG are associated with differences in resistance to other drugs and TSCC. Molecular testing may make it possible to tailor treatment and assess additional drug resistance risk according to specific mutation profile.
Robust design optimization using surrogate models
Authors: Keane Andy J , Voutchkov Ivan I 
Published: January 2020

Abstract
The use of surrogate models (response surface models, curve fits) of various types (radial basis functions, Gaussian process models, neural networks, support vector machines, etc.) is now an accepted way for speeding up design search and optimization in many fields of engineering that require the use of expensive computer simulations, including problems with multiple goals and multiple domains. Surrogates are also widely used in dealing with uncertainty quantification of expensive black-box codes where there are strict limits on the number of function evaluations that can be afforded in estimating the statistical properties of derived performance quantities. Here, we tackle the problem of robust design optimization from the direction of Gaussian process models (Kriging). We contrast two previously studied models, co-Kriging and combined Kriging (sometimes called level 1 Kriging), and propose a new combined approach called combined co-Kriging that attempts to make best use of the key ideas present in these methods.
xGASS: cold gas content and quenching in galaxies below the star-forming main sequence
Authors: Janowiecki Steven , Catinella Barbara , Cortese Luca , Saintonge Amelie , Wang Jing 
Published: January 2020

ABSTRACT
We use H i and H2 global gas measurements of galaxies from xGASS and xCOLD GASS to investigate quenching paths of galaxies below the Star forming main sequence (SFMS). We show that the population of galaxies below the SFMS is not a 1:1 match with the population of galaxies below the H i and H2 gas fraction scaling relations. Some galaxies in the transition zone (TZ) 1σ below the SFMS can be as H i-rich as those in the SFMS, and have on average longer gas depletion time-scales. We find evidence for environmental quenching of satellites, but central galaxies in the TZ defy simple quenching pathways. Some of these so-called ‘quenched’ galaxies may still have significant gas reservoirs and be unlikely to deplete them any time soon. As such, a correct model of galaxy quenching cannot be inferred with star formation rate (or other optical observables) alone, but must include observations of the cold gas. We also find that internal structure (particularly, the spatial distribution of old and young stellar populations) plays a significant role in regulating the star formation of gas-rich isolated TZ galaxies, suggesting the importance of bulges in their evolution.

ABSTRACT
Small low-mass stars are favourable targets for the detection of rocky habitable planets. In particular, planetary systems in the solar neighbourhood are interesting and suitable for precise characterization. The RedDots campaigns seek to discover rocky planets orbiting nearby low-mass stars. The 2018 campaign targeted GJ 1061, which is the 20th nearest star to the Sun. For three consecutive months we obtained nightly, high-precision radial velocity measurements with the HARPS spectrograph. We analysed these data together with archival HARPS data. We report the detection of three planet candidates with periods of 3.204 ± 0.001, 6.689 ± 0.005, and 13.03 ± 0.03 d, which are close to 1:2:4 period commensurability. After several considerations related to the properties of the noise and sampling, we conclude that a fourth signal is most likely explained by stellar rotation, although it may be due to a planet. The proposed three-planet system (and the potential four-planet solution) is long-term dynamically stable. Planet–planet gravitational interactions are below our current detection threshold. The minimum masses of the three planets range from 1.4 ± 0.2 to 1.8 ± 0.3 M⊕. Planet d, with msin i = 1.64 ± 0.24 M⊕, receives a similar amount of energy as Earth receives from the Sun. Consequently it lies within the liquid-water habitable zone of the star and has a similar equilibrium temperature to Earth. GJ 1061 has very similar properties to Proxima Centauri but activity indices point to lower levels of stellar activity.
