Based on the analysis of tectonic background and coal-accumulating environment of Jungar coalfield, the coal petrological characteristics, inorganic mineral composition, distribution and occurrence regularity of coal and gangue in No.6 coal of the Junger coalfield are studied, and the genesis is determined byutilizing the research methods of coal petrology, mineralogy and geochemistry.The study shows that the average contents of the inertinite, vitrinite and exinite in the maceral of No.6 coal in the study area are 59 %, 28 % and 13 %, respectively.Compared with the Late Paleozoic coals in other areas of North China, the content of the inertinite is high, which reflects an adequate supply of surface water during the formation of No.6 coal seam.The main inorganic minerals in coal and gangue are kaolinite and boehmite, associated with quartz, calcite, siderite, pyrite, anhydrite, anatase and svanbergite.The vertical changes of the mineral composition and main chemical elements of No.6 coal indicate that the middle of the coal seam is rich in boehmite, while the upper and lower parts are rich in kaolinite.There are three origins of kaolinite: colloidal precipitation crystallization, terrestrial transport sedimentation and volcanic ash alteration.And there are two origins of boehmite: alumina colloidal precipitation crystallization and desilication alteration of kaolinite.

The temperature sensitivities of photosynthesis and respiration remain a key uncertainty in predicting how forests will respond to climate warming. We grew seedlings of four temperate tree species, including Betula platyphylla , Fraxinus mandshurica , Juglans mandshurica and Tilia amurensis , at three temperature regimes (ambient, +2 °C, and +4 °C in daytime air temperature). We investigated net photosynthesis (Anet25), maximum rate of RuBP-carboxylation (Vcmax25) and RuBP-regeneration (Jmax25), stomatal conductance (gs25), mesophyll conductance (gm25), and leaf respiration (Rleaf) in dark (Rdark25) and in light (Rlight25) at 25 °C in all species. Additionally, we examined the temperature sensitivities of Anet, Vcmax, Jmax, Rdark and Rlight in F. mandshurica. Our findings showed that the warming-induced decreases in Anet25, Vcmax25 and Jmax25 were more prevalent in the late-successional species T. amurensis. Warming had negative impacts on gs25 in all species. Overall, Anet25 was positively correlated with Vcmax25 and Jmax25 across all growth temperatures. However, a positive correlation between Anet25 and gs25 was observed only under warming conditions, and gs25 was negatively associated with vapor pressure deficit. This implies that the vapor pressure deficit-induced decrease in gs25 was responsible for the decline in Anet25 at higher temperatures. The optimum temperature of Anet in F. mandshurica increased by 0.59 °C per 1.0 °C rise in growth temperature. While +2 °C elevated the thermal optima of Jmax, it did not affect the other temperature sensitivity parameters of Vcmax and Jmax. Rdark25 was not affected by warming in any species, and Rlight25 was stimulated in T. amurensis. The temperature response curves of Rdark and Rlight in F. mandshurica were not altered by warming, implying a lack of thermal acclimation. The ratios of Rdark25 and Rlight25 to Anet25 and Vcmax25 in T. amurensis increased with warming. These results suggest that Anet and Rleaf did not acclimate to warming synchronously in these temperate tree species. [ABSTRACT FROM AUTHOR]

China's national park establishment aims to achieve a balance between ecological conservation and regional development. This study adopts a production–living–ecological (PLE) space perspective to evaluate the park's impact. By quantifying changes and employing a combination of geographic detector and coupling coordination degree analyses, this research explores the dynamics of habitat quality and PLE space within the Wuyishan region, alongside their interrelationships. The national park's influence on the surrounding area exhibits spatial heterogeneity, evident both within and beyond park boundaries, as well as across different counties. Despite the concentration of PLE changes in the park's vicinity, particularly in densely populated urban areas, the influence of the national park on the local area is random and primarily at a low level. Importantly, the ecological space exhibits substantial changes, mirroring improvements in habitat quality. Furthermore, the coupling coordination between habitat quality changes and PLE space changes exhibits remarkable spatial variations. The complex interrelationships among PLE space necessitate a coordinated approach to their development for effective national park management. Ultimately, this investigation provides a novel perspective for the assessment of Wuyishan National Park's conservation effectiveness, contributing practical value for future endeavors.

Biomolecular condensates have emerged as an important subcellular organizing principle.sup.1. Replication of many viruses, including human respiratory syncytial virus (RSV), occurs in virus-induced compartments called inclusion bodies (IBs) or viroplasm.sup.2,3. IBs of negative-strand RNA viruses were recently shown to be biomolecular condensates that form through phase separation.sup.4,5. Here we report that the steroidal alkaloid cyclopamine and its chemical analogue A3E inhibit RSV replication by disorganizing and hardening IB condensates. The actions of cyclopamine and A3E were blocked by a point mutation in the RSV transcription factor M2-1. IB disorganization occurred within minutes, which suggests that these molecules directly act on the liquid properties of the IBs. A3E and cyclopamine inhibit RSV in the lungs of infected mice and are condensate-targeting drug-like small molecules that have in vivo activity. Our data show that condensate-hardening drugs may enable the pharmacological modulation of not only many previously undruggable targets in viral replication but also transcription factors at cancer-driving super-enhancers.sup.6.

Aims: To understand the sagittal and mobility characteristics of the thoracolumbar segment of the spine in students specialising in physical dance. METHODS: Sagittal curvature and mobility of the thoracolumbar segment of the spine was measured in 35 standard dance students, 41 Latin dance students and 43 general university students using the Spinal Mouse spine electrometer. Results: (1) In the upright position, the sagittal curvature of the T9/10 to L4/5 segment was significantly less in standard dance-specific girls than in regular female university students (p
