Authors: Assidiq F M , Prastianto R W , Mukhtasor  
Published: September 2020

Abstract
The detailed prediction of breaking waves transformation may be a main concern within the ocean structures design and development at the top of submerged flat reefs. In this preliminary analysis, phenomenon of solitary wave on the reef can be simply interpreted in two-dimensional numerical wave tank (NWT), based on the computational fluid dynamics (CFD). A more sophisticated method, large eddy simulation (LES) turbulence model together with volume of fluid (VOF) for capturing free-surface, could clarify two-phase incompressible flow Navier-Stoke equations by finite volume approach. The other approaches have been used. Existing model results, wave generation, breaking wave, and velocity distributions, devised the validity of laboratory measurements. This set of tests desired to examine the effect of different reef configurations (reef length, reef height, incident wave height, and manning coefficient) on the solitary wave propagation. Results show that the model can contribute decent predictions of the phenomenon of breaking waves on various submerged flat reef configurations.

Abstract
Due to increasing demand of the port activity it requires rapid operations of ship assisting and tug. Complex operations combined with challenging environmental disturbance often lead to ship accident that caused damaged to the jetty or the ship itself that also disrupt the overall port operation. On of the cause that lead such accidents is the limited capability of the tugboat to handle manoeuvre in extreme environment condition. Beside the safety of the operation are threatened this is also one factor that lead to decreased in tug operation effectiveness. This study intent to analyse the potential of dynamic positioning (DP) system used in the tugboat. Port of Cilacap used as study case due to special requirement as well as challenging location that lead in extreme condition of port operation. Two type of propulsion are used which is Azimuth and Void-Schneider propulsion. The conceptual system design is analysed by perform modelling simulation in Matlab software. Several condition of operation among the type of propulsion are assessed. The result is that DP system on tugboat could reduce the potential uncontrolled movement of the ship that lead to the accident. The analysis also proved that DP system of the ship can increase effectiveness of the operations by reducing the response time during manoeuvring.

Authors: Baldauf M , Claresta G , Nugroho T F 
Published: September 2020

Abstract
Vessel Traffic Services (VTS) are well established all over the globe. They become increasingly important in contributing to safety, the efficiency of maritime traffic and the protection of the marine environment. The Sunda Strait with a high traffic density in its coastal waters, serving national and international shipping, including crossing passage of the national heaviest ferry traffic, is one of the major safety concerns in Indonesia. Moreover, four accidents of ships’ collision, grounding, and fire on board have been recorded in the area from 2011-2019 as officially reported by the national safety committee (KNKT). At the same time, VTS provides valuable services to mariners. The implementation of operational standards that comply with international rules and regulations, such as IMO Resolution A.857(20), and IALA Guideline 1111, should be further developed to benefit from the broader set of VTS function. A basic marine engineering study has been done to investigate the roles of Merak VTS implemented at Sunda Strait. Spotlight empirical studies were used to collect primary qualitative data and analysis of secondary data concerning the aspects of human element, the technical and administrative work. The study revealed that the Merak VTS contributes to traffic safety and in combination with the new routeing and the mandatory ship reporting systems. Optimized procedures, advanced equipment, and well-trained VTS staff have the potentials to further improve and optimize the operation of Merak VTS.
Risk assessment due to collision between platform PHE-7 and passing vessels
Authors: Nugroho T F , Artana K B , Pratiwi E , Prastyasari F I 
Published: September 2020

Abstract
PHE is going to develop seven offshore platforms, one of the platform (PHE-7) is located at particular position that is considered close to access channel to several ports and other under development ports. Considering the mentioned development, a risk assessment study is necessary to ensure that the development would not cause any risk to current marine traffic as well as future traffic. The risk considered here is the collision between platform PHE-7 with vessels operated in that area. This study is aimed to perform risk assessment due to collision between platform PHE-7 and ships and to recommend mitigation should the risk is unacceptable. Three types of collision were developed here were head-on (powered passing vessel) collision, drifting vessel collusion, and visiting vessel collision. Each type of collision was then assessed using three main scenarios: by maintaining position of Buoy No.1 and Buoy No.3, by shifting position of Buoy No. 1 and Buoy No.3 (to align with the position of MPMT) and by combining those two scenarios. The collision risk assessment found that risk due to collision vessel-platform is in acceptable condition.
Microstructural characteristics of plasma-sprayed MCrAlY/Al2O3-13 wt.%TiO2 coating prepared by induction heating-assisted laser remelting
Authors: Zhang Peipei , Wang Dongsheng 
Published: September 2020

Abstract
The plasma-sprayed MCrAlY/Al2O3-13 wt.%TiO2 double-layer coating was treated using conventional laser remelting and induction heating-assisted laser remelting technologies to investigate the influence of laser remelting on the coating’s microstructure. The microstructural and interface characteristics of the different coatings were analyzed via scanning electron microscopy, energy dispersive spectroscopy, and x-ray diffractometry. Results showed that the Al2O3-13 wt.%TiO2 ceramic coating and MCrAlY bond coating of plasma-sprayed samples are typical lamellar structures with high porosity and that the nanostructural ceramic coating consists of fully melting and partially melting zones. A fine equiaxed grain remelting region is formed at the surface of the conventional laser-remelted ceramic coating. However, residual plasma-sprayed state is formed at the bottom of the ceramic coating. The microstructures at the bottom of the ceramic and bond coating are similar to the as-sprayed coating, but the compactness is somehow elevated. After induction heating-assisted laser remelting, the whole ceramic coating and bond coating are remelted, and compact structures are formed. Mechanical bonding occurs at the ceramic coating/bond coating interface and bond coating/substrate interface in the original as-sprayed coating. Through conventional laser remelting, mechanical bonding is the main bonding form on the specimen interface. Meanwhile, a certain degree of metallurgical bonding also exists. After induction heating-assisted laser remelting, the interface is completely transformed into metallurgical bonding. The conventional laser remelting can only strengthen the surface ceramic coating, but induction heating-assisted laser remelting can strengthen the surface ceramic layer and metal bond coating.
Recent advances in the role of the adenosinergic system in coronary artery disease
Authors: Paganelli Franck , Gaudry Marine , Ruf Jean , Guieu Régis 
Published: September 2020

AbstractAdenosine is an endogenous nucleoside that plays a major role in the physiology and physiopathology of the coronary artery system, mainly by activating its A2A receptors (A2AR). Adenosine is released by myocardial, endothelial, and immune cells during hypoxia, ischaemia, or inflammation, each condition being present in coronary artery disease (CAD). While activation of A2AR improves coronary blood circulation and leads to anti-inflammatory effects, down-regulation of A2AR has many deleterious effects during CAD. A decrease in the level and/or activity of A2AR leads to: (i) lack of vasodilation, which decreases blood flow, leading to a decrease in myocardial oxygenation and tissue hypoxia; (ii) an increase in the immune response, favouring inflammation; and (iii) platelet aggregation, which therefore participates, in part, in the formation of a fibrin-platelet thrombus after the rupture or erosion of the plaque, leading to the occurrence of acute coronary syndrome. Inflammation contributes to the development of atherosclerosis, leading to myocardial ischaemia, which in turn leads to tissue hypoxia. Therefore, a vicious circle is created that maintains and aggravates CAD. In some cases, studying the adenosinergic profile can help assess the severity of CAD. In fact, inducible ischaemia in CAD patients, as assessed by exercise stress test or fractional flow reserve, is associated with the presence of a reserve of A2AR called spare receptors. The purpose of this review is to present emerging experimental evidence supporting the existence of this adaptive adenosinergic response to ischaemia or inflammation in CAD. We believe that we have achieved a breakthrough in the understanding and modelling of spare A2AR, based upon a new concept allowing for a new and non-invasive CAD management.

Published: September 2020

Abstract
The primary mission of the European Association of Cardiovascular Imaging (EACVI) is ‘to promote excellence in clinical diagnosis, research, technical development, and education in cardiovascular imaging’. Echocardiography is a key component in the evaluation of patients with known or suspected cardiovascular disease and is essential for the high quality and effective practice of clinical cardiology. The EACVI aims to update the previously published recommendations for training, competence, and quality improvement in echocardiography since these activities are increasingly recognized by patients, physicians, and payers. The purpose of this document is to provide the general requirements for training and competence in echocardiography, to outline the principles of quality evaluation, and to recommend a set of measures for improvement, with the ultimate goal of raising the standards of echocardiographic practice. Moreover, the document aims to provide specific guidance for advanced echo techniques, which have dramatically evolved since the previous publication in 2009.
Atrial fibrillation patients undergoing percutaneous coronary intervention: dual or triple antithrombotic therapy with non-vitamin K antagonist oral anticoagulants
Authors: Goette Andreas , Vranckx Pascal 
Published: September 2020

Abstract
About 20% of all atrial fibrillation (AF) patients develop coronary artery disease, which requires coronary stenting [percutaneous coronary intervention (PCI)]. Thus, this subcohort of AF patients may require aggressive antithrombotic therapy encompassing vitamin K antagonist (VKA) or non-vitamin K antagonist oral anticoagulants (NOAC) plus aspirin and a P2Y12 inhibitor. At present, four clinical Phase IIIb trials using dabigatran, rivaroxaban, apixaban, or edoxaban, were published. These studies assessed the impact of NOACs as a part of DAT therapy vs. triple therapy. Compared with triple therapy, NOAC-based DAT has been shown to be associated with reduced major bleeding as well as intracranial haemorrhages. The benefit, however, is somewhat counterbalanced by a higher risk of stent-related ischaemia during the early phase of dual therapy. Thus, triple therapy after stenting is appropriate for at least 14 days with a maximum of 30 days. Thereafter, DAT including a NOAC is the therapy of choice in AF PCI patients to reduce the risk of bleeding during a 1 year of follow-up compared to VKA-based regimes. The present review summarizes the published study results and demonstrates differences in trial design and reported outcomes.

Abstract

Purpose
The aim of this study was to assess the feasibility of obtaining nasal and rectal swabs from general practice patients for measuring carriage of antibiotic resistant microorganisms in an area in Rotterdam (the Netherlands) with low socioeconomic status and a large immigrant population.

Methods
Data collection was from May to December 2017, in one general practice in Rotterdam. We asked adults (≥18 years) visiting the general practitioner (GP) with complaints not related to infections for one nasal and two rectal swabs and tested these for highly resistant microorganisms (HRMOs). Indicators for feasibility were recruitment rate, implementation and acceptation of data collection procedures by the participants.

Results
We obtained a nasal swab from all included 234 patients and 164 (70%) also gave rectal swabs. On average, 3 out of 30 invited patients (10%) were recruited per day. The GPs considered the workload high to inform and refer to eligible patients for the study and did this inconsistently. Most participants experienced the rectal swab procedure as burdensome and preferred assistance of a medical assistant above self-swabbing. A monetary incentive increased the willingness to provide rectal swabs.

Conclusions
Obtaining (nasal and) rectal swabs from general practice patients for study purposes proved difficult. Lessons learnt from this feasibility study will help increase participation in HRMO prevalence studies among asymptomatic general practice patients.
The Feasibility and Acceptability of an Intergenerational, Web-Based Intervention to Enhance Later-Life Family Care Planning
Authors: Kozlov Elissa , McDarby Meghan , Duberstein Paul , Carpenter Brian D 
Published: September 2020

Abstract

Background and Objectives
Adult children collaborate with older parents on care needs, yet later-life families are often uncertain about how to approach these conversations. Using the McMaster Model of Family Functioning as a framework, we developed a web-based tool for later-life families to enhance communication, knowledge, and problem solving around parent preferences for care.

Research Design and Methods
Participants were older adult parents aged 65+ and at least one of their adult children. Families answered questions about the parent’s care preferences via a web-based survey. Responses were aggregated in a tailored PDF that was distributed to each participant. Descriptive statistics were calculated to examine recruitment, retention, and satisfaction with the program. Repeated measures analyses of variance were calculated to determine preliminary efficacy of the intervention.

Results
This study included 142 participants across 49 families (n = 49 older adult parents, n = 93 adult children). Of them, 75.4% completed all three phases of the study while 18.3% completed two phases and 6.3% completed only one phase. Seventy-four percent of participants reported being satisfied or very satisfied with the intervention. At baseline, most families were modestly incongruent in their ratings of future care preferences. Participants reported increased conversations about care across the course of the study (F(1.71,179.32) = 42.18, p &lt; .001).

Discussion and Implications
This study demonstrated that a web-based intervention to enhance intergenerational communication is feasible, acceptable, and has preliminary efficacy to improve intergenerational communication. Despite recruitment challenges, similarly designed web-based resources may improve accessibility and scalability of intergenerational communication-enhancing interventions.
Machado: Open source genomics data integration framework
Authors: Mudadu Mauricio de Alvarenga , Zerlotini Adhemar 
Published: September 2020

Abstract

Background
Genome projects and multiomics experiments generate huge volumes of data that must be stored, mined, and transformed into useful knowledge. All this information is supposed to be accessible and, if possible, browsable afterwards. Computational biologists have been dealing with this scenario for more than a decade and have been implementing software and databases to meet this challenge. The GMOD's (Generic Model Organism Database) biological relational database schema, known as Chado, is one of the few successful open source initiatives; it is widely adopted and many software packages are able to connect to it.

Findings
We have been developing an open source software package named Machado, a genomics data integration framework implemented in Python, to enable research groups to both store and visualize genomics data. The framework relies on the Chado database schema and, therefore, should be very intuitive for current developers to adopt it or have it running on top of already existing databases. It has several data-loading tools for genomics and transcriptomics data and also for annotation results from tools such as BLAST, InterproScan, OrthoMCL, and LSTrAP. There is an API to connect to JBrowse, and a web visualization tool is implemented using Django Views and Templates. The Haystack library integrated with the ElasticSearch engine was used to implement a Google-like search, i.e., single auto-complete search box that provides fast results and filters.

Conclusion
Machado aims to be a modern object-relational framework that uses the latest Python libraries to produce an effective open source resource for genomics research.
Simultaneous inversion for crustal thickness and anisotropy by multiphase splitting analysis of receiver functions
Authors: Link Frederik , Rümpker Georg , Kaviani Ayoub 
Published: September 2020

SUMMARY
We present a technique to derive robust estimates for the crustal thickness and elastic properties, including anisotropy, from shear wave splitting of converted phases in receiver functions. We combine stacking procedures with a correction scheme for the splitting effect of the crustal converted Ps-phase and its first reverberation, the PpPs-phase, where we also allow for a predefined dipping Moho. The incorporation of two phases stabilizes the analysis procedure and allows to simultaneously solve for the crustal thickness, the ratio of average P- to S-wave velocities, the percentage of anisotropy and the fast-axis direction. The stacking is based on arrival times and polarizations computed using a ray-based algorithm. Synthetic tests show the robustness of the technique and its applicability to tectonic settings where dip of the Moho is significant. These tests also demonstrate that the effects of a dipping layer boundary may overprint a possible anisotropic signature. To constrain the uncertainty of our results we perform statistical tests based on a bootstrapping approach. We distinguish between different model classes by comparing the coherency of the stacked amplitudes after moveout correction. We apply the new technique to real-data examples from different tectonic regimes and show that coherency of the stacked receiver functions can be improved, when anisotropy and a dipping Moho are included in the analysis. The examples underline the advantages of statistical analyses when dealing with stacking procedures and potentially ambiguous solutions.
