Abstract
This study aims to study the effect of bioslurry and NPK fertilizers and to determine the best dosage of bioslurry and NPK fertilizer on the growth and development of butternut squash. The study was conducted from December 2018 to 21 March 2019 in Purnakarya Village, Tanralili District, Maros Regency, South Sulawesi. The study was set as a trial using a split plot design. The main plot was three bioslurry concentrations namely control, 100, and 200 mL L−1 bioslurry. The subplot was the application of NPK fertilizer types consisted of four levels, namely NPK Pak Tani (16-16-16), NPK Gold (16-10-18), NPK RG05 (15-10-30), and NPK Booster (12-6-22-3). The results of the experiment show that there was a significant interaction between bioslurry and NPK types on the stem diameter of butternut squash plants (bioslurry 100 mL L−1 and NPK Pak Tani). The bioslurry treatment showed a significant effect on fruit weight by the application of bioslurry 200 mL L−1 (978.42 g). NPK treatment significantly affected fruit length with use of NPK Pak Tani that resulted in the longest fruit (24.58 cm).

Authors: Hamdayanty H , Malinda N 
Published: October 2020

Abstract
Yam (Pachyrhizus erosus) is a tuber that is widely used in industry. Controlling the condition of yam tubers during storage is very important to maintain the quality of the industrial product. This study aimed to isolate and identify pathogen in storage that causes brown spots on yam tubers. This research was conducted based on the main principles of the Koch postulate, i.e. isolation, inoculation, re-isolation and identification. The disease was characterized with brown spots with thin mycelium on the surface of the spots. Macroscopically, the hyphae of pathogens formed were white, cotton-like on the media. Microscopically, the hypha were insulated, branched, hyaline, and forming conidia (microconidia). The conidia were oval, one or two cells, and hyaline. Based on the identification, the fungus found in the yam tuber storage was Fusarium sp., a weak pathogen that can only infect yam tubers after a wound. Fusarium infection in yam tubers in this recent study is the first report of the disease in yam tubers that causes brown spots. The results of this study can be one of the bases in determining the level of brown spot discoloration control in yam during storage.

Abstract
This study aimed to identify and formulate the influence and correlation of farmers’ practices and understanding related to the shading and pruning on the yiels of their Arabica coffee. The research was carried out in Bolokan Village, Lembang Tiroan Bittuang, Tana Toraja Regency, South Sulawesi-Indonesia. The research was in the form of surveys (study literature, observations, and interviews), with the selection of samples carried out deliberately (purposive sampling). The data was analysed with multiple linear regression using SPSS software. The results showed that the different levels of practices related with shading and pruning management provided significant effect and correlation with the yields of coffee plants. The generated multiple linear regression equation was Y = 27.983 + 1.131X1 + 0.591X2 + 2.575X3 + 1.050X4 + 0.820X5 + 1.967X6 + 1.185X7 + 0.313X8 + 0.823X9. Factors from aspects of maintenance techniques related with shading and pruning could increase the production and productivity of Arabica coffee plants. Variables of plant height adjustment, flowering and fruiting stimulation through shading, production pruning, understanding of shade plants benefits and pests and diseases control were stated to have an influence on yields (fruit) of coffee plants, while shade management, pruning time, rejuvenation pruning, and permanent shade plants were declared to have no significant effect.

Published: October 2020

Abstract
The Mallawa Coal Formation in general, has a high sulfur content even though the calorific value is quite high. Deposition environment will affect the sulfur content in coal. This study aims to determine the relationship of sulfur content to the percentage of pyrite mineral content in coal by microscopy. The research method used is field data collection, each using the channel sampling method (ply by ply) in Pujananting Barru Regency and Massenrengpulu Bone regency. Then a proximate and petrographic analysis was carried out to obtain sulfur content, and the percentage of pyrite in coal. The analysis shows that coal in the Pujananting area shows no relationship correlation between total sulfur content in coal and the percentage of pyrite minerals, so it can be concluded that sulfur in Pujananting coal is organic sulfur, which is formed together with the formation of coal starting during the peat process. While Massenrengpulu coal shows a correlation and relationship between the increase in sulfur content and the increase in the percentage of pyrite minerals, it can be concluded that the sulfur content in Massenrengpulu coal is derived from pyritic sulfur, which is strongly influenced by the depositional environment where the coal is formed.
Effectiveness of integrated waste management based on community empowerment: a cast study of Mamuju city
Authors: Ansyar M H 
Published: October 2020

Abstract
The level of urbanization in Mamuju Regency has caused an increase in the volume of waste. due to the fact that the existing landfill in Mamuju Regency is approaching maximum capacity, the local government has been looking for alternatives in processing waste through the existence of a garbage bank program. Therefore, the reduction of waste through garbage banks has existed in Mamuju Regency. The main survey in the form of interviews with relevant stakeholders has been conducted to obtain data used for the analysis of community participation. This research was conducted by looking at the effectiveness of waste management in Mamuju Regency through a case study approach to the community as customers in the garbage bank program. The waste bank is a waste and waste management model, a form of waste management business by implementing the 3R (Reduce-Reuse-Recycle) activity. Waste banks can become economic institutions where waste can be a transaction tool used in their activities, because like conventional banks that use money as the instrument, the waste bank emphasizes its focus on waste management, which is the current environmental problem.

Published: October 2020

Abstract
Sedimentation is the deposition of rock material that has been transported by water or wind power. One result of the accumulation of sediment in a basin is siltation, which can cause flooding as it did at Lake Sidenreng. This research located in Teteaji Village, Tellu Limpoe District, Sidenreng Rappang Regency, South Sulawesi Province.. This research aims to determine the characteristics of the Sidenreng Lake Quaternary sediments, specifically in the mechanism of transportation and provenance. Determining the sediment characteristics is important as the basis of planning in overcoming various problems in the lake. The methods used in this study are granulometric analysis and petrographic analysis. The sieve analysis results that the average grain size at the study site consists of 3 (three) types of sedimentary fractions, namely medium sand, fine sand, and very fine sand. This material deposited with a bed load transport distribution system and weak depositional energy. Sand material is spreading from the southwest and is gradually smoothing to the northeast at the study site. The petrographic analysis results that the provenance of sediment deposited material in Lake Sidenreng comes from volcanic breccia rocks of the Camba Formation, lava tracts of Parepare Volcano Members, and the Sandstones of the Camba Formation and Walanae Formation.

Published: October 2020

Abstract
This paper focuses on the estimation of damage contribution that each type of railway vehicle produces on the line Pescara - Ancona. The results of the numerical simulations provides fundamental information to understand the railway vehicle properties mostly influencing track damage mechanisms. The results have clearly shown the influence of the wheelset vertical forces on the damage indicators. The analysis of the specific contribution on damage by a specific railway vehicle will be particularly important to modulate track access charges by vehicle type. Moreover, simulation results will allow to adjust the unit maintenance cost of the line on the class of train, whose volumes are known.

Authors: Naveed M , Alrammal M , Bensefia A 
Published: October 2020

Abstract
Malware detection is a challenging and non-trivial task due to ever increase in several attacks and their sophistication level. Detection of such attacks demands the exploration of new approaches to generalize the attack patterns. One such approach is the use of Monte-Carlo simulations to train a reinforcement learning model. In this paper, we propose a self-adaptive Monte-Carlo simulation-based reinforcement model called Heuristic-based Generative Model (HGM), which generalizes the attack patterns in such a way that the new unknown attacks can be detected and flagged in real-time. The results show that HGM can detect a variety of malware with high accuracy.

Abstract
Methane yield is one of the important factors that indicate the anaerobic digestion (AD) process efficiency. The AD is an available treatment of recycled pulp and paper sludge (RPPS) and recycled pulp and paper wastewater (RPPW). This process protects the environment and produces methane, which is considered as renewable energy. In this study, the anaerobic treatment of the RPPW and RPPS were studied using 1L completely stirred tank reactor (CSTR) at laboratory scale with mesophilic conditions. However, a kinetic study was carried out using four models in order to compare and adjust the experimental results. The experimental results show that the RPPW and RPPS methane productions were between 691 and 945 mL/g based on volatile solid (VS), and the corresponding digestion time was about 26 days for the both experiment. The corresponding digestion time could be understood through the methane production kinetic models by digestion experiments within a short time. Different kinetics models were tested including Richards, Logistic, modified Gompertz and Cone models. The obtained results show the modified Gompertz model as the suitable model since it gives the lowest deviation from experimental results. Therefore, the proposed model could be used to accurately predict behavior of AD processes.

Abstract
Al and aluminum alloys are widely used in the transportation industry and aerospace field owing to their low density. They are always utilized as the sheathing materials, whose corrosion resistances need special attention. In the study, the electrochemical impedance spectroscopy (EIS) measurements and potentiodynamic polarization tests are performed on pure Al, aluminum alloys 2A97, 6061, 7050 and 2024. The corrosion behaviors of the five materials are respectively characterized by the resultant indicators, such as the corrosion potential E

, the corrosion current density I

c
, the corroded surface morphology and the frequency characteristics. The materials sequences that determined respectively by these indicators are compared with each other. The conflicts among these sequences are found. Then potentiostatic polarization measurements are carried out on the five materials. The instantaneous characteristic of the corrosion potential and polarization current density of each material during its corrosion process is revealed. Because of the characteristic, it is concluded that the potentiostatic polarization measurement and resultant polarization current density are more suitable to characterize the corrosion behaviors of Al and aluminum alloys. The investigation could provide help in the exploitation of new aluminum alloys with the better corrosion property.
Reinforcement learning decoders for fault-tolerant quantum computation

Published: October 2020

Abstract
Topological error correcting codes, and particularly the surface code, currently provide the most feasible road-map towards large-scale fault-tolerant quantum computation. As such, obtaining fast and flexible decoding algorithms for these codes, within the experimentally realistic and challenging context of faulty syndrome measurements, without requiring any final read-out of the physical qubits, is of critical importance. In this work, we show that the problem of decoding such codes can be naturally reformulated as a process of repeated interactions between a decoding agent and a code environment, to which the machinery of reinforcement learning can be applied to obtain decoding agents. While in principle this framework can be instantiated with environments modelling circuit level noise, we take a first step towards this goal by using deepQ learning to obtain decoding agents for a variety of simplified phenomenological noise models, which yield faulty syndrome measurements without including the propagation of errors which arise in full circuit level noise models.

Published: October 2020

AbstractBackgroundAn expanding number of mind–body therapies are being used to reduce the psychological burden of peoples living with human immunodeficiency virus (HIV). However, the effects on the immune system and mental health varied among studies.PurposeThis meta-analysis was conducted to summarize the randomized controlled trials to draw comprehensive conclusions regarding the psycho-immunological efficacy.MethodsRandom-effects models were used to assess the outcome of interest. Egger’s tests were used to identify publication bias. Subgroup and meta-regression were used to explore potential moderators. This review was registered on the PROSPERO database (CRD42019148118).ResultsNineteen randomized controlled trials with a total sample size of 1,300 were included in this meta-analysis. Regarding immune system outcome, mind–body therapy significantly improved CD4 T-cell counts (Cohen’s d = 0.214, p = .027) and maintained (0.427, p = .049). In addition, baseline CD4 T-cell counts and years since HIV diagnosis significantly moderated the efficacy of mind–body practices on CD4 improvement (all ps &lt; .001). Regarding mental health outcome, mind–body therapy significantly reduced stress, depression, and anxiety symptoms (0.422, p &lt; .001; 0.506, p &lt; .001, and 0.709, p &lt; .001, respectively) while improving quality of life (0.67, p &lt; .001).ConclusionsMeditation/yoga intervention could result in potential benefits with regard to improved CD4 T-cell counts immediately after the intervention and at long-term follow-up, while also improving their mental health. The cost-effective meditation/yoga intervention should be integrated into routine care for people living with HIV, especially for those with lower CD4 baseline and fewer years since diagnosis.
Antithrombotic selection in patients undergoing transcatheter aortic valve replacement
Authors: Lai Jennifer K , Willenborg Katie L , Berei Theodore , Rose Anne E 
Published: October 2020

Abstract

Purpose
Clinical controversy regarding the most appropriate antithrombotic regimen after transcatheter aortic valve replacement remains. Current evidence, guidelines, and recommendations are discussed.

Summary
Antithrombotic selection following transcatheter aortic valve replacement depends on a variety of patient-specific factors. For patients without a preexisting indication for anticoagulation, initial trials employed dual antiplatelet therapy as the postprocedural therapy of choice. Newer studies in this patient population, however, suggest single antiplatelet therapy reduces bleeding events without sacrificing ischemic protection. In patients with a preexisting indication for anticoagulation, warfarin plus single antiplatelet therapy, as opposed to triple antithrombotic therapy, offered similar ischemic protection while reducing clinically significant bleeding. Warfarin monotherapy was associated with a further reduction in bleeding events. One trial demonstrated the safety and efficacy of using apixaban in patients with concomitant atrial fibrillation; however, routine use of rivaroxaban increased adverse cardiac and bleeding events, leaving the utility of direct-acting oral anticoagulants in question.

Conclusion
Available evidence and current guidelines point to a lack of consensus regarding antithrombotic selection after transcatheter aortic valve replacement. Patient-specific factors and comorbidities must be considered when tailoring therapy, with an emphasis on balancing thrombotic and bleeding risks.

Abstract
The Deepwater Horizon oil spill response and clean-up (OSRC) involved over 9000 large and small vessels deployed in waters of the Gulf of Mexico across four states (Alabama, Florida, Louisiana, and Mississippi). For the GuLF STUDY, we developed exposure estimates of oil-related components for many work groups to capture a wide range of OSRC operations on these vessels, such as supporting the four rig vessels charged with stopping the spill at the wellhead; skimming oil; in situ burning of oil; absorbing and containing oil by boom; and environmental monitoring. Work groups were developed by: (i) vessel activity; (ii) location (area of the Gulf or state); and (iii) time period. Using Bayesian methods, we computed exposure estimates for these groups for: total hydrocarbons measured as total petroleum hydrocarbons (THC), benzene, toluene, ethylbenzene, xylene, and n-hexane (BTEX-H). Estimates of the arithmetic means for THC ranged from 0.10 ppm [95% credible interval (CI) 0.04, 0.38 ppm] in time periods 2 and 3 (16 July–30 September 2010) to 15.06 ppm (95% CI 10.74, 22.41 ppm) in time period 1a (22 April–15 May 2010). BTEX-H estimates were substantially lower (in the parts per billion range). Exposure levels generally fell over time and differed statistically by activity, location, and time for some groups. These exposure estimates have been used to develop job–exposure matrices for the GuLF STUDY.
