The dynamic synergy of genes and pathways in muscles in relation to age affects the muscle characteristics. Investigating the temporal changes in gene expression will help illustrate the molecular mechanisms underlying muscle development. Here we report the gene expression changes in skeletal muscles through successive age groups in Bandur, a meat type sheep of India. RNA sequencing data was generated from the longissimus thoracis muscles from four age groups, ranging from lamb to adult. Analysis of 20 highest expressed genes common across the groups revealed muscle protein, phosphorylation, acetylation, metal binding and transport as significant functions. Maximum differentiation was observed after 2.5–3 years on transition from lambs to adult. Transcriptional regulation by the TFAP2 transcription factors, IL-6 signaling and PI3K/AKT signaling pathways were enriched in younger animals. The gene-protein network demarcated key interactive genes involved in muscle development and proliferation that can be used as candidates for future research on improvement of muscle characteristics.
Effect of different management techniques on bird taxonomic groups on rice fields in the Republic of Korea
Authors: Choi Green , Do Min Seock , Son Seok-Jun , Nam Hyung-Kyu
Published: November 2021

Many bird species rely on the ecological functions of rice field habitats (e.g., paddy, levee, road, and ditch). However, recent intensive practices are causing rice fields to provide fewer suitable habitats. This study examined bird habitat usage and how it is affected by cultivation methods (e.g., eco-friendly vs conventional fields). Eco-friendly and conventional rice fields in the midwestern region of the Republic of Korea were surveyed from January 2014 to December 2016, and the species presence, number of birds, and locations of observed habitats were recorded. It was found that shorebirds and herons used more eco-friendly rice paddies with lower or no pesticide and/or herbicide use, while waterfowl used paddy habitats more than the other habitats, regardless of the amounts of pesticides and/or herbicides used. Land birds used ditches or roads in conventional rice fields more than those in fields that used pesticides and/or herbicides. Pesticide and/or herbicide use affected bird taxonomic groups differently. Consequently, the use of habitats by different bird taxonomic groups varied depending on the crop cultivation as well as the cultivation methods. These results provided valuable information for managing rice fields, which serve as habitats for birds.
DLST-dependence dictates metabolic heterogeneity in TCA-cycle usage among triple-negative breast cancer

Published: November 2021

Triple-negative breast cancer (TNBC) is traditionally considered a glycolytic tumor with a poor prognosis while lacking targeted therapies. Here we show that high expression of dihydrolipoamide S-succinyltransferase (DLST), a tricarboxylic acid (TCA) cycle enzyme, predicts poor overall and recurrence-free survival among TNBC patients. DLST depletion suppresses growth and induces death in subsets of human TNBC cell lines, which are capable of utilizing glutamine anaplerosis. Metabolomics profiling reveals significant changes in the TCA cycle and reactive oxygen species (ROS) related pathways for sensitive but not resistant TNBC cells. Consequently, DLST depletion in sensitive TNBC cells increases ROS levels while N-acetyl-L-cysteine partially rescues cell growth. Importantly, suppression of the TCA cycle through DLST depletion or CPI-613, a drug currently in clinical trials for treating other cancers, decreases the burden and invasion of these TNBC. Together, our data demonstrate differential TCA-cycle usage in TNBC and provide therapeutic implications for the DLST-dependent subsets.

Published: November 2021

We describe new tools for the processing of electron cryo-microscopy (cryo-EM) images in the fourth major release of the RELION software. In particular, we introduce VDAM, a variable-metric gradient descent algorithm with adaptive moments estimation, for image refinement; a convolutional neural network for unsupervised selection of 2D classes; and a flexible framework for the design and execution of multiple jobs in pre-defined workflows. In addition, we present a stand-alone utility called MDCatch that links the execution of jobs within this framework with metadata gathering during microscope data acquisition. The new tools are aimed at providing fast and robust procedures for unsupervised cryo-EM structure determination, with potential applications for on-the-fly processing and the development of flexible, high-throughput structure determination pipelines. We illustrate their potential on 12 publicly available cryo-EM data sets.

Non-canonical roles of autophagy proteins in endocytosis and exocytosis
Authors: Münz Christian
Published: November 2021

Autophagy, the pathways that degrade cytoplasmic constituents in lysosomes, contribute to most biological processes from aging and neurodegeneration to pathogen restriction and immunity. In recent years, it was realized that the autophagy machinery serves additional functions, primarily in endo- and exocytosis. In this review, I summarize recent advances in our understanding on how these non-canonical functions differ from canonical macroautophagy, and contribute to immune activation and viral replication. Understanding these pathways will allow us to harness them for the treatment of human diseases, as well as appreciate how cells use modules of membrane remodeling and trafficking for multiple biological functions.
Payoff‐maximization‐based adaptive hierarchical wireless charging algorithm for mobile charger in IoT
Authors: Haobo Guo , Runze Wu , Bing Qi , Bing Fan
Published: November 2021

In order to maximize the work efficiency of wireless mobile charger, a payoff‐maximization‐based adaptive hierarchical wireless charging algorithm for mobile charger is proposed. Based on the mesh structure and multi‐node charging technology, the recharging optimization for massive devices is modelled as a problem of payoff maximization. According to energy allocation, anchor point deployment and time allocation, we decompose it into three layers by the hierarchical decomposition method to obtain optimal solution quickly. The process of energy allocation and anchor point deployment in each mesh is optimized in the first two layers based on Karush–Kuhn–Trucker (KKT) condition and greedy strategy, respectively. Based on the feedback of the first two layers, the most complex problem of time allocation in the last layer is solved by our innovative gain recall mechanism. The trade‐off between the number of recharged devices and recharging time in each cycle can be achieved by only charging the devices in the meshes which are without recall gains. The simulation results prove our algorithm can adaptively adjust the ratio of moving time to recharging time in a fixed cycle, and mobile charger can always work in efficient recharging positions, whose effect is exploited utmost.
Synchronization of high‐dimensional Kuramoto models with nonidentical oscillators and interconnection digraphs
Authors: Zhang Jinxing , Zhu Jiandong
Published: November 2021

This paper investigates some synchronization behaviors of high‐dimensional Kuramoto models with nonidentical oscillators and interconnection digrphs. By using the matrix Riccati differential equation of the state error variables, it is proved that a high‐dimensional Kuramoto model can achieve local practical synchronization when the interconnection digraph is strongly connected or has a spanning tree. Compared with the existing practical synchronization literature, the results are based on general digraphs instead of complete graphs. Moreover, the complete synchronization is proved for proportional nonidentical oscillators limited on a half‐sphere and interconnected by a strongly connected digraph. Finally, some numerical simulations are given to validate the obtained theoretical results.
Effect of common branch impedance coupling and mutual inductance on current sharing of paralleled SiC MOSFETs with different layouts
Authors: Zhao Bin , Ke Junji , Yu Qiuping , Sun Peng , Cai Yumeng , Zhao Zhibin
Published: November 2021

Overcurrent failure caused by imbalanced current distribution is one of the universal failure forms of the SiC MOSFET module. The current sharing of parallel SiC MOSFETs is an important guarantee for the safe and reliable operation of parallel devices even the whole system. The existence of current coupling has a significant influence on the current sharing among paralleled SiC MOSFETs. Here, the mechanism of dynamic and static current imbalance under the different layouts resulting from current coupling generated by common branch impedance coupling and mutual inductance is comprehensively investigated by theoretical analysis and simulation validations. It is concluded that dynamic current imbalance is more serious when the drain confluence point and power source confluence point are on both sides than they are on the one side. While, the influence of the arrangement of two confluence points on the static current distribution is in reverse. Finally, a flexible and adjustable test bench is designed to verify the current sharing performance on the different layouts. The experimental results validate the correctness of the theoretical analysis. Based on these results, some guidelines are provided for the parallel‐connected application of SiC MOSFETs.

Context. Voids are the most under-dense large-scale regions in the Universe. Galaxies inhabiting voids are one of the keys for understanding the intrinsic processes of galaxy evolution, as external factors such as multiple galaxy mergers or a dense self-collapsing environment are negligible.

Aims. We present the first molecular gas mass survey of void galaxies. We compare these new data together with data for the atomic gas mass (MH I) and star formation rate (SFR) from the literature to those of galaxies in filaments and walls in order to better understand how molecular gas and star formation are related to the large-scale environment.

Methods. We observed at the IRAM 30 m telescope the CO(1−0) and CO(2−1) emission of 20 void galaxies selected from the Void Galaxy Survey, with a stellar mass range from 108.5 to 1010.3 M⊙. We detected 15 objects in at least one CO line. We compared the molecular gas mass (MH2), the star formation efficiency (SFE = SFR/MH2), the atomic gas mass, the molecular-to-atomic gas mass ratio, and the specific star formation rate (sSFR) of the void galaxies with two control samples of galaxies in filaments and walls, selected from xCOLD GASS and EDGE-CALIFA, for different stellar mass bins and taking the star formation activity into account.

Results. In general, we do not find any significant differences between void galaxies and the control sample. In particular, we do not find any evidence for a difference in the molecular gas mass or molecular gas mass fraction. For the other parameters (SFE, atomic gas mass, molecular-to-atomic gas mass ratio, and sSFR), we also find similar (within the errors) mean values between void and filament and wall galaxies when the sample is limited to star-forming galaxies. We find no evidence for an enhanced sSFR in void galaxies. Some tentative differences emerge when trends with stellar mass are studied: The SFE of void galaxies might be lower than in filament and wall galaxies for low stellar masses, and there might be a trend of increasing deficiency in the HI content in void galaxies compared to galaxies in filaments and walls for higher stellar masses, accompanied by an increase in the molecular-to-atomic gas mass ratio. However, all trends with stellar mass are based on a low number of galaxies and need to be confirmed for a larger sample.

Conclusions. The results for the molecular gas mass for a sample of 20 voids galaxies allowed us to make a statistical comparison to galaxies in filaments and walls for the first time. We do not find any significant differences of the molecular gas properties and the SFE, but we note that a larger sample is necessary to confirm this and be sensitive to subtle trends.

Context. Protoplanetary disks around young stars often contain substructures like rings, gaps, and spirals that could be caused by interactions between the disk and forming planets.

Aims. We aim to study the young (1–3 Myr) star DR Tau in the near-infrared and characterize its disk, which was previously resolved through submillimeter interferometry with ALMA, and to search for possible substellar companions embedded into it.

Methods. We observed DR Tau with VLT/SPHERE both in polarized light (H broad band) and total intensity (in Y, J, H, and K spectral bands). We also performed L′ band observations with LBTI/LMIRCam on the Large Binocular Telescope (LBT). We applied differential imaging techniques to analyze both the polarized data, using dual beam polarization imaging, and the total intensity data, using angular and spectral differential imaging.

Results. We found two previously undetected spirals extending north-east and south of the star, respectively. We further detected an arc-like structure north of the star. Finally a bright, compact and elongated structure was detected at a separation of 303 ± 10 mas and a position angle 21.2 ± 3.7 degrees, just at the root of the north-east spiral arm. Since this feature is visible both in polarized light and total intensity and has a blue spectrum, itis likely caused by stellar light scattered by dust.

Conclusions. The two spiral arms are at different separations from the star, have very different pitch angles, and are separated by an apparent discontinuity, suggesting they might have a different origin. The very open southern spiral arm might be caused by infalling material from late encounters with cloudlets into the formation environment of the star itself. The compact feature could be caused by interaction with a planet in formation still embedded in its dust envelope and it could be responsible for launching the north–east spiral. We estimate a mass of the putative embedded object of the order of few MJup.
Three-dimensional acoustic energy flow from rotating sound sources
Authors: Ocker Christof , Pannert Wolfram
Published: November 2021

A detailed study of the three-dimensional sound fields around a monopole point source in subsonic and supersonic rotation is investigated. We calculate the sound pressure, the acoustic velocity, as well as the instantaneous and time-averaged acoustic intensity fields with the advanced time approach. The advanced time approach is applied for sound sources at subsonic and supersonic rotation and yield comparable results as those obtained from the spherical harmonic series expansion method or the solution of the retarded time equation. Further, the direction of the time-averaged acoustic energy flow is derived from the acoustic intensity vectors. It is shown, that the direction of the energy flow path differs from the radial direction and depends on the rotational direction and rotational velocity. Those findings are useful, for example, to improve the acoustic absorption performance of sound absorbers and acoustic liners around turbomachines.
Microplastics abundance in gills and gastrointestinal tract of Epinephelus fuscoguttatus-lanceolatus at the Coastal of Pulau Panjang, Serang, Banten
Authors: Nabila Afra , Patria Mufti Petala
Published: November 2021

Microplastics are plastic particles in the size of <5 mm. Bioaccumulation of microplastics in the marine biotas, including fishes, occurs through the food chain. Microplastics enter the fish body through their gills and mouth. Contamination of microplastics inside the fish body can cause several effects, such as increasing toxicity effect, and growth inhibition. This research analyzed the form and amount of the microplastics found in each gill and gastrointestinal tract of the fish samples. A total of 15 samples of cantang grouper were taken from the floating net cage near Kampung Peres, Pulau Panjang. Samples were transported to the laboratory using an icebox. The gill and gastrointestinal tract of samples are isolated from their body, then destructed with HNO3 65% for 24 hours. After 24 hours, the samples were mixed with the concentrated NaCl solution with a ratio of 1:4. Microplastics form and amount are observed under the light microscope with three times repetition. The results show that the microplastics found in the gill and gastrointestinal tract of cantang groupers are mostly found in the form of fragments. The microplastics abundance in gills was 51893,33 ± 2594,67 particles/individual, and in the gastrointestinal tracts was 83926,67 ± 4196,33 particles/individual.

Published: November 2021

In this paper, an attempt has been made to assess how effective waste-collecting uses the conveyor wing. This wing-equipped conveyor will later be installed in front of the ship. In this work, a simulation model is a conveyor and wing without the ship. A numerical investigation based on Reynolds Averaged Navier Stokes (RANS) for predicting the flow pattern characteristics, velocity contour, and resistance. The focus of the present study is the impact of wing shape on waste collection in calm water through the application of numerical methods. The three variations of wing shape used are solid wing shape, square hollow wing shape, and circle hollow wing shape. It is done using speed variations of 1 to 12 knots. From the analysis of velocity contour, circle hollow wing is faster in collecting waste, then followed by hollow square wing and solid wing. From the flow pattern analysis, the circle hollow wing model is easier to make ocean waste come closer to the winged conveyor than the square wing and solid wing model. It is known that winged conveyors can only be used to collect ocean waste at low speeds. Then based on resistance comparison, it is also known that the resistance of winged conveyors from the largest to the smallest is the solid wing, hollow circle wing, and hollow square wing, respectively.
Beach slope distribution mapping using UAV in the Cirebon coastal area
Authors: Abdurrahman Umar , Pratyaksa Indrawan Fadhil , Suprijo Totok , Park Hansan
Published: November 2021

The beach slope is usually estimated using the conventional ground survey, causing the availability of this parameter data to be limited in some areas. Meanwhile, this parameter is considered crucial in the study of shoreline changes and coastal area protection as well as other coastal morphodynamic research. The aim of this study is to demonstrate an efficient technique to calculate the beach slope as well as its distribution in an area. In the daily intertidal period, the beach profile is assumed to be a static planar beach state which does not change due to the insignificant effect of erosion and accretion process. First, the shoreline data set was delineated from the tidal-varied orthomosaic using the UAV. The beach slope is then calculated by comparing the difference in tide level with the difference in the horizontal distance of shoreline points along a cross-shore transect at different times. The utilization of UAV allows mapping the shoreline in an area in several different tidal conditions, allowing the distribution of the beach slope also be mapped. This technique was then applied in the Cirebon Coastal Area and found an average beach slope of 0.105 with 0.100 being the slope class with the highest number of distributions. It was also found that due to the presence of mangroves and coastal structures, no slope conditions dominated this area. The result of beach slope calculation using this technique shows suitability with other studies and reveals UAVs’ potential in mapping the beach slope distribution more efficiently.

Published: November 2021

The fishing ground is identical and closely related to chlorophyll-a abundance in the waters, associated with its fisheries potential. This research has been conducted to determine the concentration and distribution of chlorophyll-a in the seas, especially in the Fisheries Management Area (FMA) 712 encompassing the Java Sea. The analysis used monthly time-series data collected from the satellite imagery over the last 11 years, taken through the ERDDAP website. The mean concentration of chlorophyll-a in the study area was 1.13 mg/l in June 2013. Based on 11 years of data processing, it can be concluded that the highest concentration of chlorophyll-a occurred in the west monsoon season from November to April, where increased rainfall caused the nutrient wash from terrestrial to the open waters. The lowest chlorophyll-a concentration happened in the east monsoon season from April to November, where the dry season arrived. The existence of pelagic fishes in FMA 712, such as Sardinella Lemurs and Sardinella Fimbriata, in waters highly influenced by the chlorophyll-a concentration, while Thunnus Sp. and Exocoetidae Sp. not affected significantly to the existence of chlorophyll-a concentration and its distribution.
Additional molecular data on the protected springsnail species Bythinella viridis (Poiret, 1801) (Gastropoda: Bythinellidae) suggest synonymy of related taxa
Authors: Prie Vincent E. , Cucherat Xavier
Published: November 2021

The taxonomic status of the springsnails B. viridis, B. carinulata and B. lancelevei remains unclear despite the molecular evidence data provided by Benke et al. (2009). Based on extensive sampling and the analysis of COI, 16S, 28S and ITS genes, we investigate analyze the genetic variability of Bythinella populations sampled within the area of occurrence of the three nominal taxa. Topotypic populations of B. lancelevei and B. viridis cannot could not be distinguished. Some of the populations included in the putative area of distribution range of B. carinulata form distinct supported clades, but these distinct clades are not monophyletic and the overall genetic divergence is less than the 3% barcoding gap for species of the genus the barcoding gap of c.a. 3% for Bythinella species. Therefore, we propose to synonymize these three nominal species under the name B. viridis (Poiret, 1801). Our results have important conservation implications, as they significantly expand the range of the protected species B. viridis. This species should be considered in impact studies in a large northeastern quarter of France.
Tourism carrying capacity and Social Carrying capacity: A literature review
Authors: Yusoh Mohamad Pirdaus bin , Mapjabil Jabil , Hanafi Nurhazliyana , Idris Mohd Azmi bin Muhammed
Published: November 2021

In driving sustainable tourism, the concept of carrying capacity in tourism needs to be applied. This concept of carrying capacity gives a comprehensive emphasis in the development of tourism whether in physical, social or economic aspects. If this concept is applied, it is in determining the situation in a tourist destination whether it is still in a state that can be accepted by the stakeholders in tourism, namely tourists, locals and tour operators. In this paper, emphasis is given to social carrying capacity in tourism which is one of the parts in tourism carrying capacity. This social capacity is the most difficult part to examine because it involves unequal perceptions and views from various parties. It involves interactions between tourists and tourists that cover issues of congestion and the quality of their tourism and interactions between tourists and locals or hosts that involve issues of their quality of life. Due to that, this social capacity is quite difficult to implement in some tourist areas.

Published: November 2021

Population ageing; where there is growth in the percentage of older persons in the population; is becoming a worldwide phenomenon due to better healthcare and lower birth rates. The phenomenon of population ageing brings with it both challenges and opportunities. The challenges of an ageing population include social, health and economic support of the elderly. Malaysia is recognizing the need to address this issue of financially supporting an ageing population. The purpose of the paper was to investigate the impact of business on the financial well-being (FWB) of the ageing, specifically the government retirees. A questionnaire-based survey was conducted among retirees who were in business throughout Malaysia that employed a cross sectional design. Forty-one respondents were successfully interviewed. Statistical procedures for the analyses included descriptive analysis and a profile analysis using scatterplot on the perceived business performance vs financial well-being. The survey revealed that the majority of the respondents operated business in the services, trade or retail industries which were set up and fully owned by themselves. Resource wise, the majority had very low financial capital, human capital and social capital. The study provides some empirical evidence that the retirees in business may be categorized into opportunity driven and necessity driven groups.

Reporting is a method for businesses to communicate with their various stakeholders. While the factors contributing to sustainability reporting and disclosure have been thoroughly investigated, the findings are inconclusive. Similarly, the non-financial reporting literature is disclosed of operational and non-operational activities related to ecological as well as social disclosure of firm. However, in recent years, stakeholders have increased their demand for green innovation practices (GIPs) to be included as a new component of ecological reporting. Thus, companies' proactivity in adopting green innovation reporting is reflected (GIR). This research propounds enhancing transparency in sustainability reporting by including corporations' GIPs, which will increase the transparency level of firm operations and instil greater stakeholder confidence. To accomplish this study, the legitimacy and signalling theories were used as an environmental solution.

Additionally, an exhaustive assessment of the literature was conducted in order to develop a GIR framework for enterprises to use when integrating GIPs into sustainability reporting. The outcome of this study indicates that current sustainability reporting takes a minimalist approach, with GIR being presented superficially. This non-financial reporting approach does not accurately reflect a company's genuine GIPs or the environmental effect of existing business operations. As such, this study calls for the integration of GIR into firms' sustainability reporting to accurately reflect their actual firm sustainable practices.

Academic probation students are considered a risk group as they do not meet the minimum academic requirements for a given semester. As such, factors affecting these students should be determined so that effective support or intervention programs can be carried out to assist this risk group. This paper examines the intrapersonal factors affecting academic probation students, specifically self-management, financial and health factors. Higher Education Needs Inventory for Students (HENIs) surveying tool was utilized on 81 academic probation students from Universiti Teknologi PETRONAS. The criticality of the factors affecting the academic probation students is based on the HENIs index. Data analyses by HENIs indicates that self-management factor is the most critical factor amongst the three factors with a HENIs index of 2.52. Such an index value indicates a high level of seriousness. This is also supported by a positive correlation between self-management factor of academic probation students and suicidal ideation (R2 of 0.240; p-value of 0.001). Financial and health factors both scored a HENIs index of 2.38 and 2.17, respectively. These index values indicate a moderate level of seriousness.

Langfristentwicklungen in der Kinder- und
Jugendrheumatologie
Authors: Haas Johannes-Peter , Minden Kirsten
Published: November 2021

Im Gebiet der Kinderrheumatologie gab es in den letzten Jahrzehnten immense
Fortschritte, die sowohl die Diagnostik, als auch die Therapie nachhaltig
verbessert haben. Obwohl erst seit 2003 in Deutschland offiziell als
Zusatzbezeichnung anerkannt, stehen heutzutage über 200 Kinder- und
Jugendrheumatologen (d. h. 1,4 Kinderrheumatologen pro 100 000
Kinder) für die Erkennung und Behandlung von rheumatischen Erkrankungen
bei Kindern und Jugendlichen bundesweit zur Verfügung. Neue Erkenntnisse
in der Pathogenese rheumatischer Erkrankungen und die sich stetig
weiterentwickelnde genetische Diagnostik haben das rheumatische
Krankheitsspektrum und die Behandlungsmöglichkeiten dramatisch erweitert
Internationale Forschungsnetzwerke und eine spezielle Gesetzgebung für
die Entwicklung von pädiatrischen Medikamenten führten zur
Zulassung von zahlreichen neuen Rheumamedikamenten, deren Sicherheit im
klinischen Alltag seit der Jahrtausendwende systematisch in Deutschland
untersucht wird. Maßnahmen zur Sicherung der Versorgungsqualität
wurden implementiert, Standardinstrumente zur Bewertung der
Krankheitsaktivität und Krankheitslast aus Patientensicht
eingeführt sowie Initiativen zur Verbesserung der Versorgung Betroffener
(z. B. die ProKind-Initiative) auf den Weg gebracht. Diese
Veränderungen haben die Prognose und Lebensperspektive rheumakranker
Kinder und Jugendlicher verbessert, wenngleich noch weiterer Optimierungsbedarf
besteht.
