Authors: Shanty  , Supomo Heri , Nugroho Setyo 
Published: September 2020

Abstract
Sea transportation has a vital role in the transportation system in many countries due to lower costs and higher accessibility. As in Indonesia, approximately 80% of the global trade occurs ships. This condition makes the shipping industry in Indonesia is growing, but this is not in line with improving shipping safety. Many accidents continue to occur, which pose a high risk to safety. One of the most common risks in terms of sea transportation is ship collision. Ship collisions can cause material losses, injuries, and fatalities. The International Maritime Organization (IMO) has issued various direction to prevent accidents, but in reality, collision accidents continue to occur. However, the failure to apply a solution to prevent ship collisions is not at the root cause of the accident. According to the juries of the Maritime Court and the National Transportation Safety Committee (NTSC), one of the factors causing the collision of ships in Indonesia is the human factors (the inadequate crew competencies). The purpose of this research is to analyze the human factors involved in ship collision. The method used in this research is the House of Risk (HOR) phase 1. The data used in this study was obtained through a chronological review of ship collisions, questionnaires, and interviews with shipping experts. The results of this research reveal than inadequate crew competencies only a direct cause, not the root cause of ship collisions. The root cause is that the crew recruitment process is not accountable, the harbormaster does not thoroughly check crew competency certificates, and that maritime education does not implement QSS, STCW 95 and the amendments. To prevent ship collisions, should take preventive action on the root cause of the accident and not on the direct cause.

Abstract
Estimating shaft power of a crew boat is very important to be analysed because it has high-speed operational characteristics along with limited routes. To understand the phenomena, 3 sister crew-boats with operational distance about 40-60 nautical miles every day are investigated. The daily operational time is 8 hours and the configurations are: 4.04% full speed, 13.63% economical speed, 1.81% slow speed, 7.65% snatching, 1.25% manoeuvring, 5.29% idle, and the remaining time is in standby condition.
The crew boats are fitted with a monitoring system namely SHIMOS®, in which data is sent to a server in the centre office every 2 minutes. The data consists of time capture, boat position (latitude and longitude), speed, left and right RPM engine, left and right flow-meter data engine, and average of fuel consumption data in everyday operation. Three years of data has been collected for the vessel.
The present study proposed characteristics of crew-boat shaft power, which affected by external factors using Artificial Neural Network (ANN) back propagation method and optimisation in 4 hidden layers and 40 neurons with relative error 6.2%. The results demonstrates good agreement with previous popular method that using statistical models.

Published: September 2020

Abstract
Learning from nature, the humpback whale can swim faster than other baleen whales. The humpback whale has the flipper with wavy leading edges (WLE), which has an improvement of hydrodynamic performance. The WLEs have the function to generate vortices to maintain lift and to prevent stall at high angles of attack. This research aim is to find out the WLE effect on hydrodynamic performance in different wing aspect ratios (AR), whose profile is the rectangular wing of NACA 0018 as a baseline wing. The WLE profile was designed by a sinusoidal function. We focused on steady flow conditions in both the experiments and numerical simulations. The experimental work was conducted in the circular water channel at Hiroshima University, Japan. Meanwhile, the numerical work was employed using RANS simulation with SST k-ω turbulence model. Based on the results, we clarified that the increase of AR could possess a higher lift coefficient (Cl), and then physically interpreted the WLE effect on various aspect ratios. This knowledge could be expanded into the application of eco-friendly energy-saving devices such as fin stabilizers of ships and wind turbines to improve hydrodynamic performance.

Published: September 2020

Abstract
The Indonesian government has just issued a policy plan of international hub port location, Integrated Port Network (IPN) to suppressing logistic cost. This study examines the IPN impact on shipping and port sectors by the total cost. The methods used in this research are set covering problem and cost comparison between transshipment in Singapore and directly shipped containers through the hub ports. As a result, IPN will be able to decrease the cost of logistics by 8%, which is the total cost of 9,220 billion.Rp/year. The current ships used are 1,500–2,500 TEUs. Meanwhile, the largest ship size by the IPN concept is to 3,000TEUs and the smallest is 300TEUs, the greatest number of ships is on the Priok-Port of Singapore route as many as 14 units. On the port sector, not all designated ports are able to accommodate and serve the 2,000 TEU ships due to the facilities and port infrastructure. At least it costs Rp 1.183 trillion-Rp so that the concept of 7 hub ports can be implemented. After the implementation of IPN will cause a potential loss for both Tj Priok and Tj Perak. On the contrary, IPN will increase the potential throughput of the Kijing, Makassar, Bitung, and Sorong.
Determination of Business Port Terminal Value Using Income Approach
Authors: Wedana Y A , Gunarta I K 
Published: September 2020

Abstract
Under PT X’s long-term plan to increase the company’s value, PT X plans to acquire one of PT Y’s container terminal business units. The acquisition requires several stages of the process from due diligence to estimation of the acquisition value obtained from the valuation results. Business valuation as a critical stage is a process to produce an opinion or an estimate of the fair value of a company. The results of the business appraisal can then be used in investment \ decision making, generally for business development, mergers, and acquisitions. There are 3 (three) approaches in conducting business valuation, namely asset-based approach, market-based approach, and income-based approach. This research will focus on the company’s acquisition plan using income approach (income-based approach). This approach is used by considering the going concern assumption, or the business that is being assessed will continue to run and generate revenue. Two methods can be used to determine the value of a business in income approach (Income-based approach), namely the method of income capitalization (capitalized of income method) and discounted cash flow method (discounted cash flow). This study aims to determine the business value of PT Y’s container terminal business unit and the maximum acquisition value used as a consideration in the acquisition. This research uses an income-based approach with a discounted cash flow (DCF) method. The making of financial models begins with making a profit and loss terminal container service projection, then the free cash flow calculation is performed. Furthermore, based on the free cash flow that has been calculated with a discount rate from the Weighted Average Cost of Capital (WACC) which provides the total value of all company capital, the company value that represents the value of the container terminal unit is Rp. 9,171,633,437,067. To find out the maximum acquisition value obtained by calculating the company’s return on investment that refers to the cost of capital of PT X. To get a positive rate of return, the IRR value must be greater than the WACC. Under the calculations, the maximum acquisition price of Rp. 7,500,000,000,000 (IRR 9.66%) with a WACC value of PT X of 7.6%. The results of this calculation become material in the acquisition process with PT Y as the owner of the container terminal.

Abstract
This study aims to determine the effect of using silica gel and iron powder to inhibit the degradation rate of biodiesel. The method used in this study was an experiment of biodiesel storage for 8 weeks. In this research, an acid number test and bacterial TPC test will be used as a parameter to measure the degradation rate of biodiesel. From this study, it is known that the use of silica gel and iron powder can reduce the rate of degradation of biodiesel and can reduce bacterial growth. This is evidenced by decreasing the degradation rate to 46% in the use of silica gel and iron powder with composition 3.2 g / l silica gel and 2.4 g / l iron powder. while in tank 7 (control) experienced the highest increase of up to 112%. In testing TPC bacteria it is known that in tank 2 which has decreased by 99.8%. while in tank 7 there was an increase in the number of bacteria by 37.6%.
Soft sample deformation, damage and induced electromechanical property changes in contact- and tapping-mode atomic force microscopy
Authors: Saadi M A S R , Uluutku Berkin , Parvini Cameron H , Solares Santiago D 
Published: September 2020

Abstract
Probe-induced soft sample damage in atomic force microscopy (AFM), as well as the resulting alteration of local mechanical and electrical properties of the material are explored, specifically comparing contact-mode and intermittent-contact-mode imaging methods. In our experiments, performed on conductive polymer films, induced changes are present in contact-mode imaging while they are negligible or absent in tapping-mode imaging. To understand this result, a viscoelastic parameter extraction is performed, which suggests that permanent sample deformation can readily occur for tip-sample interactions with a duration on the timescale of contact-mode interactions. Using the extracted viscoelastic parameters, a dynamic AFM simulation is conducted, which suggests that the material responds more elastically with reduced or absent sample damage in tapping-mode AFM, due to the higher rate of mechanical deformation and shorter timescales.
Rationing care in COVID-19: if we must do it, can we do better?
Authors: Rockwood Kenneth 
Published: September 2020

Abstract
The COVID-19 pandemic has seen a proposal for frailty to be used as a rationing criterion. This commentary suggests circumstances under which that is defensible: in the face of lack of capacity to treat everyone, and as an alternative to age in stratifying risk. How best to stratify risk is likely to evolve and may include information about illness severity and dynamic measures. Current research must focus on mobilizing better, COVID-19-specific prognostic information, with a goal of best discriminating which lives are most and least likely to be saved should scarcity of resources dictate that not everyone can receive critical care.

Published: September 2020

Abstract

Objective
To investigate the accuracy of the Social and Emotional Assessment-short version (Mini-SEA) to differentiate subgroups of behavioral variant of frontotemporal dementia (bvFTD) and Alzheimer’s disease (AD) defined according to executive performance.

Methods
bvFTD (n = 21), AD (n = 20), and healthy controls (HC, n = 23) underwent the Mini-SEA, comprising the Facial Emotion Recognition Test (FERT) and the faux-pas test. AD and bvFTD patients were classified according to their performance in the Frontal Assessment Battery into dysexecutive and nondysexecutive subgroups.

Results
The area under the curve (AUC) values for the faux-pas test were 0.87 (dysexecutive-bvFTD vs. dysexecutive-AD) and 0.96 (non-dysexecutive-bvFTD vs. nondysexecutive-AD). The AUC values for FERT were 0.99 (dysexecutive-bvFTD vs. dysexecutive-AD) and 0.65 (nondysexecutive-bvFTD vs. nondysexecutive-AD); the AUC values for the Mini-SEA (total-score) were 0.95 (dysexecutive-bvFTD vs. dysexecutive-AD) and 0.88 (nondysexecutive-bvFTD vs. nondysexecutive-AD).

Discussion
Social Cognition tests accurately distinguish bvFTD from AD regardless of the executive profile.
The role of boundary length and adjacent patch contrast in guppy mate choice
Authors: Sibeaux Adélaïde , Camduras Thomas , Endler John A 
Published: September 2020

Abstract
The presence of various combinations of adjacent colors within polymorphic species’ color pattern could have a major impact on mate choice. We studied the role of pattern geometry in predicting mate choice in guppies using boundary strength analysis (BSA). BSA estimates the visual contrast intensity between two adjacent color patches (ΔS) weighted by the lengths of the boundaries between these adjacent color patches. We measured both the chromatic (hue and saturation) and achromatic (luminance) ΔS for each pair of adjacent patches. For each male’s color pattern, we measured BSA as both mean (mΔS) and coefficient of variation (cvΔS) of all ΔS weighted by their corresponding boundary lengths. We also determined if specific color patch boundaries had an impact on female preferences and whether these predicted overall male contrast (mΔS). We found that males with a higher mΔS were more attractive to females and that six boundaries containing either fuzzy black or black as one of the pair colors significantly affected female preferences, indicating that 1) females favored highly conspicuous males and 2) melanin-based patches could be used as a signal amplifier, not only for orange but for other colors.

Published: September 2020

Abstract

Summary
Transposon calling cards is a genomic assay for identifying transcription factor binding sites in both bulk and single cell experiments. Here, we describe the qBED format, an open, text-based standard for encoding and analyzing calling card data. In parallel, we introduce the qBED track on the WashU Epigenome Browser, a novel visualization that enables researchers to inspect calling card data in their genomic context. Finally, through examples, we demonstrate that qBED files can be used to visualize non-calling card datasets, such as Combined Annotation-Dependent Depletion scores and GWAS/eQTL hits, and thus may have broad utility to the genomics community.

Availability and implementation
The qBED track is available on the WashU Epigenome Browser (http://epigenomegateway.wustl.edu/browser), beginning with version 46. Source code for the WashU Epigenome Browser with qBED support is available on GitHub (http://github.com/arnavm/eg-react and http://github.com/lidaof/eg-react). A complete definition of the qBED format is available as part of the WashU Epigenome Browser documentation (https://eg.readthedocs.io/en/latest/tracks.html#qbed-track). We have also released a tutorial on how to upload qBED data to the browser (http://dx.doi.org/10.17504/protocols.io.bca8ishw).
A systems-biology model of the tumor necrosis factor (TNF) interactions with TNF receptor 1 and 2
Authors: Prada Juan Pablo , Wangorsch Gaby , Kucka Kirstin , Lang Isabell , Dandekar Thomas , Wajant Harald 
Published: September 2020

Abstract

Motivation
Clustering enables TNF receptors to stimulate intracellular signaling. The differential soluble ligand-induced clustering behavior of TNF receptor 1 (TNFR1) and TNFR2 was modeled. A structured, rule-based model implemented ligand-independent pre-ligand binding assembly domain (PLAD)-mediated homotypic low affinity interactions of unliganded and liganded TNF receptors.

Results
Soluble TNF initiates TNFR1 signaling but not TNFR2 signaling despite receptor binding unless it is secondarily oligomerized. We consider high affinity binding of TNF to signaling-incompetent pre-assembled dimeric TNFR1 and TNFR2 molecules and secondary clustering of liganded dimers to signaling competent ligand–receptor clusters. Published receptor numbers, affinities and measured different activities of clustered receptors validated model simulations for a large range of receptor and ligand concentrations. Different PLAD–PLAD affinities and different activities of receptor clusters explain the observed differences in the TNF receptor stimulating activities of soluble TNF.

Practice-derived data on non-vitamin K antagonist oral anticoagulant therapy to complement observations from randomized trials
Authors: Domek Magdalena , Gumprecht Jakub , Ding Wern Yew , Lip Gregory Y H , Lane Deirdre A 
Published: September 2020

Abstract
Anticoagulation is fundamental in the management of patients with atrial fibrillation (AF). The study aims to provide a comparative review of the major phase III randomized clinical trials (RCTs) and real-world data (RWD) from reliable, high-grade Phase IV studies that assess the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) vs. vitamin K antagonists (VKAs). Observational studies based on nationwide or health insurance database records on the use of NOACs vs. VKAs in patients with AF were included. We performed a comparison of the efficacy and safety characteristics associated with NOACs vs. VKAs in RCTs and RWD. Although RCTs provide strong support for evidence-based practice, RWD may be used to reflect the broader picture of various clinical settings, provide supplementary insight and fulfil knowledge gaps. Both study types confirmed the safety and efficacy of NOACs in preventing stroke and thromboembolism in patients with AF. In comparison to VKAs, NOACs were associated with reduced risk of ischaemic events and lower rates of adverse events such as major bleeding or intracranial haemorrhage. Administration of NOACs might be associated with increased risk of dose-related gastrointestinal bleeding and myocardial ischaemic events, especially in the early treatment period after switching from VKAs. Special care should be taken in challenging clinical situations like severe renal or hepatic impairment when the treatment regimen needs to be considered individually. Randomized clinical trial and RWD studies are complementary and present comparable findings, affirming that NOACs are safe and effective for anticoagulation of patients with AF in daily clinical practice.
Non-vitamin K antagonist oral anticoagulants therapy for atrial fibrillation patients undergoing electrophysiologic procedures
Authors: Steffel Jan 
Published: September 2020

Abstract
Over the last 10 years since the introduction of non-vitamin K antagonist oral anticoagulants (NOACs) into routine clinical practice our experience with these drugs has increased tremendously, also in the context of patients undergoing electrophysiology procedures. While some open questions remain, the available evidence indicates that for the majority of cases, these interventions can safely be performed on NOACs if study-based standard operating procedures are in place and followed. This review summarizes the most current trial evidence and guidelines on the use of NOACs for patients undergoing cardioversion, atrial fibrillation ablation, and device implantations, based on previous work of the author and others.
The importance of adherence and persistence in the elderly atrial fibrillation patient
Authors: Hylek Elaine M 
Published: September 2020

Abstract
Older adults with atrial fibrillation are at the highest risk of ischaemic stroke yet are the least likely to be prescribed anticoagulant therapy, adhere to this therapy, and maintain long-term persistence with this therapy. The reasons for this under treatment are multifactorial and include patient-driven factors, physician-driven factors, medical system complexities, and current unknowns regarding the biology and natural history of AF. Understanding these challenges to stroke prevention and addressing identified barriers to medication adherence and persistence in this vulnerable age group will improve outcomes related to AF.
Black women, separation allowances and citizenship in the French Caribbean during the First World War
Authors: Joseph Michael 
Published: September 2020

Abstract
Historians of the First World War have shown great interest in the logics of gender and citizenship that governed the payment of separation allowances to soldiers’ dependants and the ways in which these allowances structured subsequent European welfare regimes. Using the specific case of the French Caribbean, this article brings together two comparatively understudied dimensions of this history: the wartime legislation’s implementation and the colonial context. It explores how discourses around race and labour, which had evolved in the context of emancipation and its aftermath, resonated with the assumptions encoded in the legislation. It then examines how Black Caribbean women mobilized to push back against the exclusions which followed. In so doing, it speaks to Black women’s interventions in the political life of the Third Republic to resist their exclusion from the emerging French welfare state.
