Abstract
Jiangxi Province is located in the tropical zone of mid-high temperature geothermal resources along the southeastern coast of China. Geothermal geological surveys, the exposed natural hot springs, the explored geothermal walls and the reported geothermal research results related to the potential of geothermal energy indicate the abundant geothermal resources and the high formation potential of mid-high temperature geothermal resources in Jiangxi Province. However, the research level of geothermal resources in this area is relatively low, the distribution of geothermal hotspots is uneven, and the specific resource distribution, geothermal temperature, and resource quantity are not well understood, so it is difficult to systematically carry out the mid-high geothermal development in this province. Therefore, we collect the data of the study area, established a multi-index evaluation model combining experience and data, and carried out the evaluation of geothermal resources advantageous target areas and the analysis of geothermal impact indicators. The main purpose of this study is to use analytic hierarchy process (AHP) and principal component analysis (PCA) to qualitatively and quantitatively evaluate the mid-high temperature geothermal resources of the Jiangxi Province, and also to propose a dual-method comparative evaluation model for the study of the mid-high geothermal target area. Based on the quantitative data from geological, hydrological and geophysical sources and the extensive experience of regional workers and geologists, by using the AHP and PCA, we divide the study area into 7 geothermal resource potential zones and 38 geothermal optimal target areas. It is determined that deep large faults are the most critical indicators affecting the distribution of geothermal resources in the study area, followed by the heat storage value of the silicon enthalpy equation and the magmatic rocks. This study is of great significance for geothermal research in similar areas, multi-index and multi-data model analysis, and accurate positioning of high-quality geothermal resource target areas. It also has important guiding significance for the follow-up development planning of geothermal resources the research area or further research on the geothermal target area.

Abstract
Landscapes nearby glaciers are disproportionally affected by climate change, still we lack the information on microclimate variation that is required to understand impacts of climate change on these ecosystems and their biodiversity. Here we use near-subsurface soil temperatures in 175 stations from polar, equatorial and alpine glacier forelands to reconstruct temperatures at high resolution, assess spatial differences in microclimate change from 2001 to 2020, and estimate whether microclimate heterogeneity might buffer the severity of warming impacts on organisms. Temporal changes in microclimate are tightly linked to broad-scale trends, but the rate of global warming showed spatial heterogeneity, with faster warming nearby glaciers and during the warm season, and an extension of the snow-free season. Still, the fine-scale spatial variability of microclimate is one-to-ten times larger than the temporal change experienced, indicating the potential for microclimate to buffer climate change, possibly allowing organism to withstand, at least temporarily, the effects of warming.

Abstract
For many pumping stations that draw water from sediment-laden rivers, the flow patterns in their intake structure are disordered due to sediment deposition, which seriously threatens the safe operation of projects. In order to accurately construct the complex and refined three-dimensional (3D) geometric model of the intake structure, and further explore the hydraulic characteristics of the water-sediment two-phase flow inside, this paper proposes a reverse modeling method and carries out numerical simulation. A typical forward intake structure in the arid region of Northwest China is selected as the research object. According to the point cloud data of the intake structure obtained by the 3D laser scanner, the curved surface models are rebuilt and imported into ICEM-CFD for improvement, thereby obtaining the 3D computational domain model of the actual intake structure; after lossless docking with FLUENT, the hydraulic characteristics are analyzed by applying the Realizable k-ε turbulence model coupled with the Mixture multiphase flow model considering interphase slip; finally, the reliability of the simulation is verified by in-situ flow measurements. Results demonstrate that the method can precisely reflect the actual geometric boundary and siltation of intake structure, and the numerical model can accurately identify the two-phase flow; the siltation improves the local flow field structure of the forebay to some extent, but cause the loss of the overall hydraulic performance of the intake structure. This study can provide a scientific reference for the geometric model construction and hydraulic analysis of intake structures with complex boundary and sediment deposition.

Abstract
Metasurfaces can perform high-performance multi-functional integration by manipulating the abundant physical dimensions of light, demonstrating great potential in high-capacity information technologies. The orbital angular momentum (OAM) and spin angular momentum (SAM) dimensions have been respectively explored as the independent carrier for information multiplexing. However, fully managing these two intrinsic properties in information multiplexing remains elusive. Here, we propose the concept of angular momentum (AM) holography which can fully synergize these two fundamental dimensions to act as the information carrier, via a single-layer non-interleaved metasurface. The underlying mechanism relies on independently controlling the two spin eigenstates and arbitrary overlaying them in each operation channel, thereby spatially modulating the resulting waveform at will. As a proof of concept, we demonstrate an AM meta-hologram allowing the reconstruction of two sets of holographic images, i.e., the spin-orbital locked and the spin-superimposed ones. Remarkably, leveraging the designed dual-functional AM meta-hologram, we demonstrate a novel optical nested encryption scheme, which is able to achieve parallel information transmission with ultra-high capacity and security. Our work opens a new avenue for optionally manipulating the AM, holding promising applications in the fields of optical communication, information security and quantum science.

Abstract
Background: Bosnia and Herzegovina (B&H) and Serbia are developing countries in the Western Balkans that share similar social and political legacy from the former Yugoslavia including the health care system and are not members of European Union. There are very scarce data on COVID – 19 pandemic from this region.
Materials and methods: This observational prospective study was conducted in two dialysis and transplant centres in B&H and Serbia, during the COVID – 19 pandemic. We monitored: demographic and epidemiological data, preventive and control measures in dialysis centres, clinical course and outcomes of dialysis and transplanted patients with COVID – 19. Data were collected by filling out an agreed questionnaire and were analysed and compared for two consecutive time periods: February – June 2020 with total number of 767 studied patients, and July – December 2020 with total number of 749 studied patients.
Results: For a period of 11 months, from February to December 2020, there were 82 ICHD patients, 11 CAPD patients and 25 kidney transplant patients who tested positive for COVID-19. In the first study period, the incidence of COVID – 19 positive in Tuzla was 1.32% among ICHD patients, and there were no positive CAPD patients, nor patients with kidney graft. The incidence was significantly higher in both centres in the second time period. These data correspond to incidence in general population. Total deaths of COVID-19 positive patients was 0% in Tuzla DC and 45.45% in Niš DC during first, and 16.67% in Tuzla DC and 23.44% in Niš DC during the second period.
Conclusion: Very bad overall survival was direct reflection of unpreparedness of our medical systems for such situations, and reminder of importance of preventive measures. Spreading of COVID-19 and similar respiratory infections within DC can be achieved using cheap measures that we have described here. It might also shift fight in more developed countries toward cheaper and simpler preventive measures, which could result in money and lifesaving results.
Responses of westerly jet over Asia versus North America in Last Glacial Maximum and their attributions

Published: September 2022

Abstract
The Northern Hemisphere westerly jet (WJ) during the Last Glacial Maximum (LGM) exhibits significant anomalies from present day. However, the total responses of Northern Hemisphere WJ, as well as the relative influences of different individual LGM forcings are still unclear. By using a coupled climate model, our results show that the seasonal variation of Northern Hemisphere WJ in LGM is characterized by distinct regional discrepancies. The WJ is intensified and shifts southward in North America, while generally weakens and displaces northward in central Asia. Over Japan, the WJ is enhanced and moves southward in summer but attenuated and shifts northward in winter. The change of WJ has a close relationship with the mid troposphere temperature anomalies which are resulted from different external forcings. In summer, the ice sheet albedo plays a leading role in wind fields at mid-to-high latitudes of Northern Hemisphere by causing a zonal wave-like response of temperature. While in winter, the ice sheet topography dominates the wind fields across North America to North Atlantic by inducing a northwest-southeast orientated tripole temperature response in this region. The effects of orbital parameters and greenhouse gases largely contribute to the alteration of upper wind fields over Asia and North Pacific by motivating a dipole response of temperature.

Published: September 2022

Abstract
Recently the number of people exercising at home has increased especially due to the COVID19 pandemic. Therefore, the need for no contact exercise instructions is in great demand since physical access to the gym is limited or discouraged. To meet this demand, many online exercise instruction videos are available. However, the systems are both passive and have no real time feedback to aid the user. In this work,we propose an AI based fitness monitoring system (AI Fitness Coach) that can offer real time guidance during exercise. The AI Fitness Coach, consists of a pose recognition unit, a fitness movement analysis unit, and a feedback unit. The user captures their pose by a fixed camera. The pose recognition unit processes the captured image and outputs the recognition result to the fitness movement analysis unit. After the results are processed by the fitness movement analysis unit, advice is output from the device through video or voice. On comparison to existing methods, the proposed method results are at par and encouraging.

Abstract
The Burkholderia cepacia complex (BCC) is a Gram-negative bacterial, including Burkholderia contaminans species. Although the plain Burkholderia is pervasive from taxonomic and genetic perspectives, a common characteristic is that they may use the quorum-sensing (QS) system. In our previous study, we generated the complete genome sequence of Burkholderia contaminans SK875 isolated from the respiratory tract. To our knowledge, this is the first study to report functional genomic features of B. contaminans SK875 for understanding the pathogenic characteristics. In addition, comparative genomic analysis for five B. contaminans genomes was performed to provide comprehensive information on the disease potential of B. contaminans species. Analysis of average nucleotide identity (ANI) showed that the genome has high similarity (> 96%) with other B. contaminans strains. Five B. contaminans genomes yielded a pangenome of 8,832 coding genes, a core genome of 5,452 genes, the accessory genome of 2,128 genes, and a unique genome of 1,252 genes. The 186 genes were specific to B. contaminans SK875, including toxin higB-2, oxygen-dependent choline dehydrogenase, and hypothetical proteins. Genotypic analysis of the antimicrobial resistance of B. contaminans SK875 verified resistance to tetracycline, fluoroquinolone, and aminoglycoside. Compared with the virulence factor database, we identified 79 promising virulence genes such as adhesion system, invasions, antiphagocytic, and secretion systems. Moreover, 45 genes of 57 QS-related genes that were identified in B. contaminans SK875 indicated high sequence homology with other B. contaminans strains. Our results will help to gain insight into virulence, antibiotic resistance, and quorum sensing for B. contaminans species.

Abstract
The Spanish toothcarp (Aphanius iberusValenciennes, 1846) is a small fish species endemic to the eastern coastline of the Iberian Peninsula. Along its area of distribution, it mainly inhabits brackish waters which can exhibit large fluctuations in temperature and salinity throughout the year. Aphanius iberus belongs to the family Aphaniidae within the order Cyprinodontiformes and is currently listed as “Endangered” (category IUCN: EN), facing a very high risk of extinction in the wild. The genetics of A. iberus are not well-known since most studies have only evaluated the genetic structure of the species under a conservation framework in order to identify its potential conservation units. In the present study, the entire mitochondrial genome of A. iberus was obtained for the first time in the context of an A. iberus reference genome. The mitogenome was reconstructed and aligned against 83 cyprinodontiformes and two outgroup taxa to create the phylogenetic reconstruction of A. iberus. PartitionFinder was first used to test for the best evolutionary model for both coding and non-coding genes and the phylogenetic analysis was performed using two methods: Maximun-Likelihood approximation (IQ-Tree) and Bayesian inference (MrBayes). Our results show that A. iberus forms a sister group with Orestias ascotanensis, a cyprinodontiform species native to South America. We believe the information gained from this study is valuable for improving our understanding of the historical evolution of A. iberus and that it can be useful for future genomic studies.
Hypoxia Actives HIF-1α and Affects Genes Expression Associated with Hypoxia and Transcriptional Regulation of PHD by HIF-1α under Hypoxia in Tegillarca granosa
Authors: Peng Zhilan , Liu Xiaomin , Zhan Yu , Liu Minhai , Zha Shanjie , Bao Yongbo 
Published: September 2022

Abstract
Background Hypoxia-inducible factor-1α (HIF-1α) is actived in response to hypoxia and can regulate genes expression related to hypoxia pathway. However, far less is known about how HIF-1 regulates downstream target genes to produce hypoxia adaptive responses in molluscaunder hypoxia and whether the activity of PHDs under hypoxia is controlled by HIF-1α.
Methods and results. qRT-PCR was performed to determine the expression of Tg-HIF-1α ,Tg-PHD, Hb, Mb and dual-luciferase reporter analysis was used to detect the transcriptional activity. Results showed that expression level of Tg-HIF-1α and Tg-PHD were both highest in gill and lowest in adductor muscle. Additionally, a significant expression increase in Tg-HIF-1α and Tg-PHD was observed after hypoxia 8 h when DO concentrations were 0.5 mg/L and 2.0 mg/L (P<0.01), then decreased slowly after 24 h, It was still higher than that normoxia (P<0.01), after 72 h, Tg-PHD expression showed no significant change (P>0.05). After 8 h at 0.5 mg/L of DO, Hb expression decreased in hemocytes (P<0.01); at the same 0.5 mg/L of DO, in the hepatopancreas, the expression of MbI and MbII were increased (P<0.01) after hypoxia 24 h and 120 h, respectively. The dual-luciferase reporter analysis revealed that Tg-HIF-1α could transactivate the promoter of PHD but not of Hb.
Conclusion Hypoxia induced significant changes in Tg-HIF-1α, Tg-PHD, Tg-Hb and Tg-Mb expressions. Tg-HIF-1α can bind to PHD’s hypoxia response elements but not Hb’s. It appears that the regulation of Tg-HIF-1α transcript levels may be a useful biomarker for hypoxia exposure in the environment.

Published: September 2022

Abstract
Drought is a major limiting factor of Brassica napus (rapeseed) and potassium plays important roles in rapeseed drought tolerance. Previous studies have reported that rapeseed cultivars characterized by different potassium status showed contrasting drought tolerance. However, the molecular mechanism underlying drought tolerance remains unclear. In this study, comparative transcriptome analysis was conducted between drought-tolerant cultivar Youyan57 and drought-sensitive cultivar Chuanyou36 exposed to PEG6000 simulated drought stress with two potassium levels (1.0 and 0.01 mM K2SO4, referred to NK and LK, respectively). A total of 1689 differentially expressed genes (DEGs) were identified at NK. DEGs involved in photosynthesis, glutathione biosynthesis, IAA signal transduction were up-regulated in Youyan57 at NK. By contrast, the down-regulated DEGs were significantly enriched in biosynthesis of amino acids, cysteine and methionine metabolism and glucosinolate biosynthesis. Transcription profile was affected seriously at LK treatment since only 1050 DEGs were identified. DEGs involved in biosynthesis reduced largely. Furthermore, the conspicuous up-regulation of protein phosphatase 2C in Chuanyou36 could lead to more severe drought stress at LK, which negatively participated in abscisic acid (ABA) signal transduction. Taken together, the comparative transcriptome analysis identified a set of drought-regulated genes involved in several pathways, and provided important information about molecular mechanisms underlying rapeseed drought tolerance.

Published: September 2022

Abstract
Industrial alumina ceramics require high surface accuracy when assembled to critical components of devices, for which high-quality milling has become an integral process. To mill the alumina ceramics for high-quality and high-efficiency, this paper used a composite strategy via the femtosecond laser burst-mode. Milling the same structure, the roughness of the bottom surface of the grooves was reduced by up to 10.69% compared to the optimal processing results in a single process, and processing efficiency was maximized with a 49.91% increase. Different laser parameters such as energy fluence, spot overlap ratio, scanning spacing were investigated for the processing quality and efficiency of alumina ceramics in the single-pulse mode. The effect of the burst-mode on the optimization of the milling results was analyzed and discussed.To mill the alumina ceramics with high-efficiency, the composite processing strategy was used. Meantime, the paper proposed a high-quality and high-efficiency composite milling strategy via the femtosecond laser burst-mode, which provided a reference for processing other materials.
Exploring different multi-state structures when studying patterns of antidepressant medication use in women with breast cancer and matched healthy controls

Published: September 2022

Abstract
Background: A breast cancer diagnosis is related with psychological distress and possibly with an increased use of antidepressants. Multi-state models can be used to study a number of clinically meaningful research questions related to patterns of medication use such as the total probability of being or total length of stay in an antidepressant medication or discontinuation period over time.
Methods: Different multi-state structures may correspond to different research questions and vary from simple ones, such as a single-event survival analysis setting, up to bidirectional and recurrent multi-state structures, with each structure having its own traits, advantages, interpretations, and limitations. There are also a number of factors to consider when applying a multi-state model such as choosing a time-scale for the transition rates, borrowing information across transitions and relaxing the proportional hazards assumption. We explore the use of different multi-state structures when studying antidepressant medication use patterns among women diagnosed with invasive breast cancer (n=18313) and age-matched cancer-free women (n=92454) from the Swedish population, using the information in Breast Cancer Data Base Sweden 2.0 (BCBaSe 2.0).
Results: While each structure has its own utility, the more complex structures -bidirectional and recurrent– are able to take into account the intermittent nature of the prescribed medication data and deliver estimates about the total probability and total length of stay of an individual in an antidepressant medication status or discontinuation periods during their follow-up. Sensitivity analyses over different definitions of the medication cycle and different approaches when modelling the transition intensity rates (Markov, semi-Markov or mix of the two) show that the estimates of the complex structures are quite stable. However, even these structures present limitations that should be taken into account during the implementation of the models.
Conclusions: In this study we provide insight into the use, interpretation and limitations of different multi-state structures when applied to prescribed medication data. The conclusions drawn provide a better understanding of the application of multi-state models in epidemiology.
