Abstract The groupers, locally known as “kerapu” in Indonesia, are commercially valuable fish in Indonesia, including Aceh. The groupers are the first fish family to be plundered in most countries’ fisheries industries. However, the biodiversity information of the groupers fished in Aceh is limited. This study was aimed to inventories the grouper species landed in Aceh fish landing sites. The data collection was performed in some fish landing locations (TPI) located in Aceh. In general, this study revealed that Aceh has high grouper diversity. In total, 35 species of the Epinephelidae family were recorded. Epinephelus was the dominant genus found, followed by Cephalopholis, Plectropomus, Variola, Aethaloperca, Anyperodon, and Hyporthodus. Simeulue, Weh island, and Banda Aceh were the locations with the highest diversity of grouper in Aceh. Overall, the data collected from this study would be beneficial for the future management plan of grouper in Aceh and Indonesia.

AbstractThe JAXA’s Martian Moons Exploration (MMX) mission is planned to reveal the origin of Phobos and Deimos. It will remotely observe both moons and return a sample from Phobos. The nominal instruments include the TElescopic Nadir imager for GeOmOrphology (TENGOO) and Optical RadiOmeter composed of CHromatic Imagers (OROCHI). The scientific objective of TENGOO is to obtain the geomorphological features of Phobos and Deimos. The spatial resolution of TENGOO is 0.3 m at an altitude of 25 km in the quasi-satellite orbit. The scientific objective of OROCHI is to obtain material distribution using spectral mapping. OROCHI possesses seven wide-angle bandpass imagers without a filter wheel and one monochromatic imager dedicated to the observation during the landing phase. Using these two instruments, we plan to select landing sites and obtain information that supports the analysis of return samples. Graphical Abstract

AbstractIn order to investigate the origin of Phobos and Deimos, the Japanese Martian Moons eXploration (MMX) mission is scheduled for launch in 2024. MMX will make comprehensive remote-sensing measurements of both moons and return regolith samples from Phobos to Earth. Geodetic measurements of gravity, shape, and rotation parameter of a body provides constraints on its internal structure reflecting its origin and evolution. Moments of inertia are important parameters to constrain the internal mass distribution, but they have not been well determined for the Martian moons yet. We discuss the mission requirements related to the moments of inertia to detect a potential heterogeneity of the mass distribution inside Phobos. We introduce mission instruments and operational strategies to meet the mission requirements. We present a preliminary imaging strategy from a quasi-satellite orbit for a base shape model that is expected to be created at the early stage of the mission. Geodetic products including ephemeris, gravity field, rotation parameter of Phobos, and spacecraft orbit are of importance not only for the geodetic study, but also for interpreting data from various mission instruments and selecting possible landing sites.

AbstractElevation and visual data from Chang’E-2, Mars Viking, and MOLA were transformed into 3D models and environments using unity and unreal engine to be implemented in augmented (AR) and virtual reality (VR) applications, respectively. The workflows for the two game development engines and the two purposes overlap, but have significant differences stemming from their intended usage: both are used in educational settings, but while the AR app has to run on basic smartphones that students from all socio-economic backgrounds might have, the VR requires high-end PCs and can therefore make use of respective devices’ potential. Hence, the models for the AR app are reduced to the necessary components and sizes of the highest mountains on Luna and Mars, whereas the VR app contains several models of probe landing sites on Mars, a landscape containing the entire planet at multiple levels of detail and a complex environment. Both applications are enhanced for educational use with annotations and interactive elements. This study focuses on the transfer of scientific data into game development engines for the use in educational settings using the example of scales in extra-terrestrial environments.

Humans usually contract dengue by being bitten by arthropods, and more than 3.6 billion people are at risk per year. Although studies are conducted to screen and trace out the possible pathophysiology of the virus, an adequate receptor-based study has not been completed. Understanding how the dengue virus (DV) engraves its landing sites requires identification of such cellular receptors. In many model studies, heparan sulfate (HS) has been reported to act as a DV receptor under various conditions. However, the physiological relevance of these findings remains uncertain. Therefore, it is still unclear whether HS is used by viral strains or not, and if at all used by clinical or non-cell culture-adapted strains of DV. The present review aims to identify relevant experimental evidences that confirm the possible interaction between envelope protein and HS chains. We collected data from a series of studies to conclude the interactive role.
