Published: July 2023

Context.The galactic component in clusters is commonly thought to be generally nonrotating and in a dynamical state different from that of a collisionally relaxed system. In practice, a test for such conditions is often not available.Aims.We consider the member galaxies of the two clusters Abell S1063 and MACS J1206.2−0847 and study the possible presence of mean rotation and some properties of their distribution in phase space. We look for empirical evidence of factors normally found in collisionally relaxed systems and other characteristics of violently relaxed collisionless systems.Methods.Starting from the CLASH-VLT data, we obtained positions, stellar masses, and individual line-of-sight velocities for a large number of galaxies (NAS1063 ≈ 1200 andNM1206 ≈ 650) extending out to ≈1.6 (Abell) and ≈2.5 (MACS) times the radiusr200. We studied the spatial distribution of the galaxy velocities and the properties of the available galaxy sets when divided into stellar mass bins. To test the presence of velocity dispersion anisotropy, we compared the results based on the Jeans equations with those obtained by assuming a specific form of the galaxy distribution function incorporating the picture of violent relaxation, where the total gravitational potential is imposed as set by the available gravitational lensing observations.Results.We find evidence of systematic rotation in both clusters, with significant rotation in each core (within 0.5′ from the center) and no signatures of rotation at large radii. While no signs of energy equipartition were found, there is a clear indication of (stellar) mass segregation. Velocity dispersion anisotropy is present and qualitatively similar to what has been found in violently relaxed collisionless systems. This last conclusion is strengthened by the overall success in matching the observations with the predictions of the physically justified distribution function.

Objective This study aimed to determine neurodevelopmental outcomes of preterm infants born at <29 weeks' gestational age (GA) with bronchopulmonary dysplasia and pulmonary hypertension (BPD–PH) at 18 to 24 months' corrected age (CA).
Study Design In this retrospective cohort study, preterm infants born at <29 weeks' GA between January 2016 and December 2019, admitted to level 3 neonatal intensive care units, who developed BPD and were evaluated at 18 to 24 months' CA in the neonatal follow-up clinics were included. We compared demographic characteristics and neurodevelopmental outcomes between the two groups: Group I: BPD with PH and Group II: BPD with no PH, using univariate and multivariate regression models. The primary outcome was a composite of death or neurodevelopmental impairment (NDI). NDI was defined as any Bayley-III score < 85 on one or more of the cognitive, motor, or language composite scores.
Results Of 366 eligible infants, 116 (Group I [BPD–PH] =7, Group II [BPD with no PH] = 109) were lost to follow-up. Of the remaining 250 infants, 51 in Group I and 199 in Group II were followed at 18 to 24 months' CA. Group I and Group II had median (interquartile range [IQR]) birthweights of 705 (325) and 815 g (317; p = 0.003) and median GAs (IQR) were 25 (2) and 26 weeks (2; p = 0.015) respectively. Infants in the BPD–PH group (Group I) were more likely to have mortality or NDI (adjusted odds ratio: 3.82; bootstrap 95% confidence interval; 1.44–40.87).
Conclusion BPD–PH in infants born at <29 weeks' GA is associated with increased odds of the composite outcome of death or NDI at 18 to 24 months' CA.

Abstract
Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus-associated pneumonia and acute respiratory distress syndrome (ARDS) were often associated with hyperinflammation and elevation of several serum inflammatory markers but usually less than what is observed in non-coronavirus disease (COVID) ARDS. Elevated inflammatory markers such as C-reactive protein, interleukin (IL)-6, etc., are associated with severe infection. This study identified subphenotypes of COVID-19 ARDS patients by latent profile analysis in a cohort of Indian patients.
Methods Data of n = 233 adult Indian patients with laboratory-confirmed SARS-CoV-2 infection admitted to a tertiary care teaching hospital were analyzed in this retrospective study. Only patients with acute respiratory failure (defined by partial pressure of oxygen/fraction of inspired oxygen ratio < 200 mm Hg) and chest X-ray showing bilateral infiltrates were included.
Results The patients' mean (standard deviation) age was 53.3 (14.9) years, and 62% were male. A two subphenotypic model was formulated based on the lowest Bayesian information criterion. Neutrophil-to-lymphocyte ratio and serum IL-6 were latent variables in that model (entropy 0.91). The second phenotype (hyperinflammatory) had lower platelet count (p = 0.02), higher serum creatinine (p = 0.004), higher C-reactive protein (p = 0.001), higher ferritin (p < 0.001), and serum lactate dehydrogenase (p = 0.009). Age-adjusted hospital mortality (p = 0.007), duration of hospital stay (p < 0.001), and duration of intensive care unit stay (p < 0.001) were significantly higher in the second subphenotype.
Conclusion Two distinct but overlapping subphenotypes were identified in SARS-CoV-2-associated respiratory failure. Hyperinflammatory subphenotype was associated with significantly poor short-term outcomes.
Regeneration of Liangzhu culture: multimedia exhibition, simulated restoration, innovative cultural products, nearby area integration, virtual reality and augmented reality
Authors: Liu Zhihong 
Published: July 2023

AbstractSince Liangzhu culture was recognised as the earliest monarchical period in the history of China, its vitality has been acknowledged both by the public and archaeologists in China and worldwide. Several contributions to current regeneration practices, including exhibitions, innovative cultural products, and integrations with nearby areas, remain in the preliminary stages due to the relative youth of the Liangzhu archaeological sites and museum, while their adoption of VR and AR technologies is also limited in practice. Referencing relevant cases in the literature and an interview with a manager involved with the archaeological work on Liangzhu culture, this article provides recommendations for exhibitions that emphasise the adoption of digital and multimedia displays and simulated restorations. Meanwhile, innovative cultural products require improvements related to design and development that match customer preferences. To integrate Liangzhu culture with nearby tourist attractions, comprehensive studies are needed on the spiritual connections that local communities develop with their original living spaces and the forms of their participation in heritage conservation practices. This article also presents several technical improvements for VR and AR, such as new methods for constructing digital models and the choice of presentation medium. Potential usages for AR technology with simulated restorations, interactive activities, innovative cultural products, and new public spaces nearby have also been suggested. Supported by the detailed discussion of restoration practices in these recommendations, this article provides an integrative regeneration plan for all “large” and “earthen” Neolithic archaeological cultures that resemble Liangzhu culture.
Impact of increased antiretroviral therapy use during the treatment as prevention era in Australia
Authors: Gray Richard T. 
Published: July 2023

Background We analysed the impact of increased antiretroviral therapy (ART) on HIV epidemiology and healthcare costs in Australia during the ‘Treatment-as-prevention’ and ‘Undetectable equals Untransmissible (U=U)’ eras. Methods We conducted a retrospective modelling analysis between 2009 and 2019 to calculate the potential impact of early initiation of ART and treatment-as-prevention on HIV among gay and bisexual men (GBM). The model incorporates the change in the proportion diagnosed, treated, and virally suppressed, as well as the scale-up of oral HIV pre-exposure prophylaxis (PrEP) and the change in sexual behaviour during this period. We simulated a baseline and a no ART increase scenario and conducted a costing analysis from a national health provider perspective with cost estimates in 2019 AUD. Results Increasing ART use between 2009 and 2019 averted an additional 1624 [95% percentile interval (PI): 1220–2099] new HIV infections. Without the increase in ART, the number of GBM with HIV would have increased from 21 907 (95% PI: 20 753–23 019) to 23 219 (95% PI: 22 008–24 404) by 2019. HIV care and treatment costs for people with HIV increased by $296 (95% PI: $235–367) million AUD (assuming no change in annual healthcare costs). This was offset by a decrease in the lifetime HIV costs (with 3.5% discounting) for those newly infected of $458 (95% PI: $344–592) million AUD, giving a net cost saving of $162 (95%: $68–273) million AUD (and a benefits-to-cost ratio of 1.54). Conclusions Increasing the proportion of Australian GBM on effective ART between 2009 and 2019 likely resulted in substantial reductions in new HIV infections and cost savings.
Quantum optomagnetics in graphene
Authors: Abedi Sina , Hamed Majedi A 
Published: July 2023

Abstract
Graphene can be magnetized through nonlinear response of its orbital angular momentum to an intense circularly polarized light. This optomagnetic effect can be well exemplified by the inverse Faraday effect (IFE) where an optically-generated DC magnetization leads to graphene’s optical activity. We provide a single-particle quantum mechanical model of an IFE in graphene by solving Schrödinger’s equation in the presence of a renormalized Hamiltonian near a Dirac point in the presence of circularly polarized monochromatic light. We derive an analytical expression for DC magnetization based on non-perturbative and dressed states of quasi-electrons where their energy spectrum is isotropically gapped by the circularly polarized light. Optical rotatory power is then computed through the gyroelectric birefringence where a measurable polarization rotation angle under moderate and intense optical radiations is predicted.

Abstract
Monolithic integration of III–V optoelectronic devices on Si platform is gaining momentum, since it enables advantages of low cost, less complexity and high yield for mass production. With the aim of achieving advances in monolithic integration, the challenges associated with lattice mismatch between III–V layers and Si substrates must be overcome, as a low density of threading dislocations (TDs) is a prerequisite for the robustness of the integrated devices. In this paper, we have investigated and compare different types of dislocation filter layers (DFLs) from InGaAs asymmetric step-graded buffer layer (ASG), InGaAs/GaAs strained-layer superlattices, and quaternary alloy InAlGaAs ASG, on the functionality of reducing TD density (TDD) for GaAs buffer layers on Si. Compared to other DFLs, the sample with InAlGaAs ASG buffer layer shows the lowest average TDD value and roughness, while the decrease of TDD in the sample with InAlGaAs ASG buffer layer can be understood in terms of the hardening agent role of aluminium in the InAlGaAs ASG. By further optimising the InAlGaAs ASG through thermal cyclic annealing, we successfully demonstrate a low surface TDD of 6.3 ± 0.1 × 106 cm−2 for a 2 μm GaAs/InAlGaAs ASG buffer layer grown on Si. These results could provide a thin buffer design for monolithic integration of various III–V devices on Si substrates.

Published: July 2023

Abstract
Highly purified and solution-processed semiconducting carbon nanotubes (s-CNTs) have developed rapidly over the past several decades and are near-commercially available materials that can replace silicon due to its large-area substrate deposition and room-temperature processing compatibility. However, the more s-CNTs are purified, the better their electrical performance, but considerable effort and long centrifugation time are required, which can limit commercialization due to high manufacturing costs. In this work, we therefore fabricated ‘striped’ CNT network transistor across industry-standard 8 inch wafers. The stripe-structured channel is effective in lowering the manufacturing cost because it can maintain good device performance without requiring high-purity s-CNTs. We evaluated the electrical performances and their uniformity by demonstrating striped CNT network transistors fabricating from various s-CNT solutions (e.g. 99%, 95%, and 90%) in 8 inch wafers. From our results, we concluded that by optimizing the CNT network configurations, CNTs can be sufficiently utilized for commercialization technology even at low semiconducting purity. Our approach can serve as a critical foundation for future low-cost commercial CNT electronics.
Hull Girder Ultimate Strength Analysis of 17500 LTDW Oil Tanker under the Combined Global and Local Load using Explicit Finite Element Analysis
Authors: Zakki Ahmad Fauzan , Sisworo Sarjito Joko 
Published: July 2023

Abstract
This study investigates the hull girder’s ultimate strength of 17500 LTDW Oil Tanker. The explicit finite element analysis is carried out to estimate the hull girder longitudinal strength of the Oil Tanker. The numerical analysis starts with the longitudinal strength analyses that examine the ship’s structural response behavior due to sagging and hogging bending moment load. The structural strength analyses were conducted to determine the maximum structural response behavior for withstanding the operational load. Afterward, the hull girder’s ultimate strength is undertaken to reflect the progressive collapse behavior of the oil tanker structure under the combined global bending moment and local hydrostatic pressure load. The explicit finite element analysis is performed to estimate the ultimate strength behavior, considering the effect of the hydrostatic pressure load and the material nonlinearities. The typical 17500 LTDW oil tanker represents Indonesia’s common oil vessel that supports national fuel oil distribution. Furthermore, this study can recognize the oil tanker’s ultimate hull girder strength characteristics.

Abstract
Indonesia has enormous potential in the maritime sector, specifically in the tourism sector. Tourism in Indonesia is developing in several regions. There is one of the tourism destinations in Gresik Regency, that is Dalegan Beach. Dalegan Beach is located in Dalegan Village, Panceng District which has an area of 6.39 km2. Dalegan Beach has an area of about 2.3 ha and a beach length of about 180 meters. Dalegan Beach has a potential eco-tourism because of sloping beach topography, calm waves and white sand. However, to develop the Dalegan Beach as an eco-tourism have several obstacles. There are lack of infrastructure to support tourist attractions, unclear collaboration between the village community and the local government, and poor management so that the development of eco-tourism is not optimal. This study aims to improve the management of Dalegan Beach as eco-tourism, which involved all stakeholders include local governments, communities, regional consultative bodies and universities. The Analythic Hierarchy Process (AHP) method is applied on this study in order obtaining an integrated and sustainable beach management formula based on priority scale. There are five factors used for the criteria in this analysis process, those are environmental, economic, social, infrastructure, and legal. Furthermore, the Expert Choice software are used to process inputs gained from the stake holders. The result of analysis indicates the order of alternative priority management that must be carried out namely human resource empowerment of 0.336 or (33.6%), then the development of tourist destinations with a value of 0.256 or (25.6%), further development of tourism marketing of 0.238 or (23.8%) and finally industrial development of 0.170 or (17.0%).

Published: July 2023

Abstract
RoPax is the most famous ship in the world that simultaneously carries multipurpose such as passengers, cargo, and vehicles in bulk. Cargo ships experience the most accidents, but RoPax ships contribute the most casualties worldwide. RoPax OCD is practical and economical for the short-medium route but vulnerable in intact dynamic stability that causes capsize. The paper analyses the data of RoPax Opened Car Deck (OCD) accidents in range time (2003-2021) in Indonesia water that is reviewed by the Response Amplitude Operator (RAO). Internal ship data is obtained from Indonesia’s National Transportation Safety Committee (NTSC), and external data on wave characteristics are obtained from Global Ocean Waves Reanalysis Waves of Copernicus Marine Service. From RAO analysis of eight capsizing cases of RoPax OCD show that 62.5% occur in sub-critical (effect of low stability moment), 25% occur in supercritical (a result of small weight inertia moment), and 12.5% occur in critical (a consequence of small damping moment). The conclusion is that stability problems are the leading cause of the capsizing of RoPax, so existing ships must improve their stability or be diverted to operation areas with suitable wave characteristics.

Authors: Siswanto N , Rosdaniah S 
Published: July 2023

Abstract
Blue economy (BE) has become one of global actual issues with a multifaceted concept to generate new growth sources from ocean while ensuring environmental sustainability. Indonesia has initiated BE programs since 2012 in Bali and West Nusa Tenggara, featuring an integrated upstream and downstream marine development. However, the targeted outcome of this effort has not yet achieved, due to a number of challenges, including coordination difficulties among stakeholders. An innovation to promote multi-stakeholder collaboration is needed to capture the benefit from the ocean economy. This paper enriches the literature on the BE coordination model by introducing a pilot project of innovative stakeholder engagement platform called BluEconNet. This platform is a digital medium for increasing the involvement of multiple stakeholders to build a participative BE. The platform is designed based on the result of an exploratory approach through literatures review, Focus Group Discussion with representative of stakeholders, combined with semi-structured interviews with representative from institutions. The involvement of stakeholders in the platform is expected to encourage multiple connections and support innovative solutions to provide policymakers with comprehensive information on the ocean economy in order to accelerate the BE development in Indonesia.

Abstract
The increasing demand for Liquified Natural Gas (LNG) is directly proportional to the risk of LNG Facilities. One of the risks is fire due to leakage of the LNG storage tank at the LNG terminal. This study aims to predict the impact of jet fire on humans due to leaks of LNG storage tanks using Fire Dynamic Simulator and predict the probability of injury or death due to the accident. This simulation uses LNG storage tank capacity as variations including primary data obtained from field surveys. The first results are Hazard and Operability (HAZOP) analysis which found that the cause of the leak was caused by 3 aspects: overpressure, temperature, and corrosion. In addition, the simulation results show 21 deaths due to thermal radiation that occurred in the 20000 m3 storage tank, with a radius of 250 m from the LNG storage tank and a radiation dose of 9,787,223 W4/3sm−8/ 3. Finally, it is recommended that the LNG storage tank be 1200 m3. have a minimum radius of 80 m from the office or housing while the LNG storage tanks of 7500 m3 and 20000 m3 must be 185 m and 250 m apart from the residence.

Published: July 2023

Abstract
Scope for of research publications on ocean current energy has increased, resulting in high innovation from ocean energy technology and available models for numerical equations in article publications. Reviews for mapping studies on the development of technology and numerical equations are still rarely carried out. This review refers to articles that use equipment used at sea and are based only on ocean currents for research. From a variety of results of the investigation, it can be expected to be used as material for further studies to find research materials that can be discussed collectively or need to be handled further. The objective of present review study is scanning condition of technology used for analysis and find out the types of numerical equations that are often used in papers in recent years. The result is that various areas of innovation have been investigated in current energy conversion technologies that increase performance and durability and reduce the impact on the environment and have summarised alternative numerical analysis commonly used for current energy conversion technologies.
