水韭属是一类具有异形孢子的古老石松类植物，全属物种均被列入国家重点保护野生植物。该文报道了在浙江省长兴县新发现的一个四倍体水韭属居群。基于形态学、孢粉学和细胞学证据，将该物种命名为长兴水韭（Isoëtes changxingensis），并详细描述了其形态特征。长兴水韭与保东水韭（I. baodongii）在植株形态及孢子纹饰方面都较为相似，不同之处在于其染色体为44条，大孢子极面直径为317~411 μm（平均为360 μm）（vs.染色体22条，大孢子极面直径为390~510 μm，平均为450 μm）。与同为四倍体的隆平水韭（I. longpingii）在孢子大小方面极为接近，不同之处在于其根状茎3裂，叶片中间宽为2~3 mm，大孢子表面具棘刺-脊条状纹饰（vs.根状茎2裂，叶片中间宽度为1 mm，大孢子表面具瘤状-脊条状纹饰）。该种与中华水韭（I. sinensis）的区别在于其大孢子较小，表面纹饰不同，叶片长为20~60 cm（vs.大孢子极面直径为340~450 μm，平均为409 μm，具脊条状突起纹饰，叶片长为15~30 cm）。长兴水韭目前仅分布于其模式产地的一处沟渠，由于其分布区狭窄，野生居群数量较少，栖息地环境受到人为干扰，因此根据IUCN红色名录评估标准可将长兴水韭暂定为濒危（EN）等级。由于该种面临生境破坏和野外人为刈割的风险，因此很有必要开展迁地保护及野外回归等相关工作。该文编制了中国已报道的水韭属物种的分种检索表，为该属物种的鉴定和保护工作提供了参考。

The amount of power contained in the variations in galaxy star-formation histories (SFHs) across a range of time-scales encodes key information about the physical processes which modulate star formation. Modelling the SFHs of galaxies as stochastic processes allows the relative importance of different time-scales to be quantified via the power spectral density (PSD). In this paper, we build upon the PSD framework and develop a physically motivated, 'stochastic' prior for non-parametric SFHs in the spectral energy distribution (SED)-modelling code prospector. We test this prior in two different regimes: (1) massive, |$z = 0.7$| galaxies with both photometry and spectra, analogous to those observed with the LEGA-C survey, and (2) |$z = 8$| galaxies with photometry only, analogous to those observed with NIRCam on JWST. We find that it is able to recover key galaxy parameters (e.g. stellar mass, stellar metallicity) to the same level of fidelity as the commonly used continuity prior. Furthermore, the realistic variability information incorporated by the stochastic SFH model allows it to fit the SFHs of galaxies more accurately and precisely than traditional non-parametric models. In fact, the stochastic prior is |$\gtrsim 2\times$| more accurate than the continuity prior in measuring the recent star-formation rates (log SFR |$_{100}$| and log SFR |$_{10}$|⁠) of both the |$z = 0.7$| and |$z = 8$| mock systems. While the PSD parameters of individual galaxies are difficult to constrain, the stochastic prior implementation presented in this work allows for the development of hierarchical models in the future, i.e. simultaneous SED-modelling of an ensemble of galaxies to measure their underlying PSD.

We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range (⁠|$-3.5 \lt \rm [Fe/H] \lesssim -1.3$|⁠). We find abundance patterns that are effectively indistinguishable from the bulk of Indus and Jhelum, a pair of smaller stellar streams proposed to be dynamically associated with Wukong/LMS-1. We confirmed a carbon-enhanced metal-poor star (⁠|$\rm [C/Fe] \gt +0.7$| and |$\rm [Fe/H] \sim -2.9$|⁠) in Wukong/LMS-1 with strong enhancements in Sr, Y, and Zr, which is peculiar given its solar-level [Ba/Fe]. Wukong/LMS-1 stars have high abundances of α elements up to |$\rm [Fe/H] \gtrsim -2$|⁠ , which is expected for relatively massive dwarfs. Towards the high-metallicity end, Wukong/LMS-1 becomes α-poor, revealing that it probably experienced fairly standard chemical evolution. We identified a pair of N- and Na-rich stars in Wukong/LMS-1, reminiscent of multiple stellar populations in globular clusters. This indicates that this dwarf galaxy contained at least one globular cluster that was completely disrupted in addition to two intact ones previously known to be associated with Wukong/LMS-1, which is possibly connected to similar evidence found in Indus. From these ≥3 globular clusters, we estimate the total mass of Wukong/LMS-1 to be |${\approx }10^{10} \, \mathrm{M}_\odot$|⁠ , representing ∼1 per cent of the present-day Milky Way. Finally, the [Eu/Mg] ratio in Wukong/LMS-1 continuously increases with metallicity, making this the first example of a dwarf galaxy where the production of r -process elements is clearly dominated by delayed sources, presumably neutron-star mergers.

To explore the correlation between blood pressure variability（BPV）and vascular endothelial function induced by nocturnal hypoxia events in obstructive sleep apnea（OSA）patients. Methods：Between February 2022 and April 2023，a total of 131 moderate to severe OSA patients were studied from the departments of Sleep Medicine Centers in three different hospitals， including the Affiliated Huai’an No.1 People’s Hospital of Nanjing Medical University，etc. Continuous non-invasive blood pressure （BP）monitoring was performed simultaneously during polysomnography（PSG）to calculate BPV induced by hypoxic events，the gap between the peak value of systolio blood pressure（SBP）and the lowest SBP during a hypoxia event reflects the amplitude of BP fluctuation（ΔBP）；the number of times ΔBP≥10 mmHg per hour/oxygen desaturation index（ODI）indicates the percentage of hypoxia-induced BP fluctuation. Endothelial function was assessed by flow -mediated dilation（FMD），and patients were divided into normal endothelial function group（n=70）and endothelial dysfunction group（n=61）according to the FMD value. The study analyzed and compared the BPV parameters between the two groups，aiming to explore the factors associated with BPV. Results：There were no significant differences between the two groups of patients in age，sex distribution，body mass index，and OSA severity. Compared with the normal endothelial function group，the endothelial dysfunction group exhibited higher Bnocturnal systolic peak BP［（152.0±7.2） mmHg vs.（148.1±8.8）mmHg］，nocturnal diastolic peak BP［（89.8±5.7）mmHg vs.（87.5±6.6）mmHg］，ΔBP［（15.3±2.9）mmHg vs. （13.3±2.7）mmHg］，the percentage of BP fluctuation［（63.5±14.3）% vs.（44.8±10.7）%，all P < 0.05］，a n d endothelin-1［（50.7± 7.0）ng/L vs.（47.8 ± 8.5）ng/L，P < 0.05］. After adjusting the baseline data of patients，the line regression model showed that the nocturnal SBP peak，the percentage of BP fluctuation，and ΔBP were all positively correlated with FMD（all P < 0.05）. Conclusion：For moderate-to-severe OSA patients，the elevation of BPV induced by nocturnal hypoxia events is closely correlated to vascular endothelial dysfunction. [ABSTRACT FROM AUTHOR]

We infer the dynamical masses of stars across the Hertzsprung–Russell (H–R) diagram using wide binaries from the Gaia survey. Gaia 's high-precision astrometry measures the wide binaries' orbital motion, which contains the mass information. Using wide binaries as the training sample, we measure the mass of stars across the 2D H–R diagram using the combination of statistical inference and neural networks. Our results provide the dynamical mass measurements for main-sequence stars from 0.1 to 2 M⊙, unresolved binaries, and unresolved triples on the main sequence, and the mean masses of giants and white dwarfs. Two regions in the H–R diagram show interesting behaviours in mass, where one of them is pre-main-sequence stars, and the other one may be related to close compact object companions like M dwarf-white dwarf binaries. These mass measurements depend solely on Newtonian dynamics with minimal assumptions on eccentricities, providing independent constraints on stellar evolutionary models, and the occurrence rate of compact objects.

This work presents the Globular cluster Extra-tidal Mock Star (GEMS) catalogue of extra-tidal stars and binaries created via three-body dynamical encounters in globular cluster cores. Using the particle-spray code Corespray , we sample |$N=50\, 000$| extra-tidal stars and escaped recoil binaries for 159 Galactic globular clusters. Sky positions, kinematics, stellar properties, and escape information are provided for all simulated stars. Stellar orbits are integrated in seven different static and time-varying Milky Way gravitational potential models where the structure of the disc, perturbations from the Large Magellanic Cloud and the mass and sphericity of the Milky Way's dark matter halo are all investigated. We find that the action coordinates of the mock extra-tidal stars are largely Galactic model independent, where minor offsets and broadening of the distributions between models are likely due to interactions with substructure. Importantly, we also report the first evidence for stellar stream contamination by globular cluster core stars and binaries for clusters with pericentre radii larger than five kiloparsecs. Finally, we provide a quantitative tool that uses action coordinates to match field stars to host clusters with probabilities. Ultimately, combining data from the GEMS catalogue with information of observed stars will allow for association of extra-tidal field stars with any Galactic globular cluster; a requisite tool for understanding population-level dynamics and evolution of clusters in the Milky Way.

We model the stellar abundances and ages of two disrupted dwarf galaxies in the Milky Way stellar halo: Gaia -Sausage Enceladus (GSE) and Wukong/LMS-1. Using a statistically robust likelihood function, we fit one-zone models of galactic chemical evolution with exponential infall histories to both systems, deriving e-folding time-scales of τin = 1.01 ± 0.13 Gyr for GSE and |$\tau _\text{in} = 3.08^{+3.19}_{-1.16}$| Gyr for Wukong/LMS-1. GSE formed stars for |$\tau _\text{tot} = 5.40^{+0.32}_{-0.31}$| Gyr, sustaining star formation for ∼1.5–2 Gyr after its first infall into the Milky Way ∼10 Gyr ago. Our fit suggests that star formation lasted for |$\tau _\text{tot} = 3.36^{+0.55}_{-0.47}$| Gyr in Wukong/LMS-1, though our sample does not contain any age measurements. The differences in evolutionary parameters between the two are qualitatively consistent with trends with stellar mass M ⋆ predicted by simulations and semi-analytic models of galaxy formation. Our inferred values of the outflow mass-loading factor reasonably match |$\eta \propto M_\star ^{-1/3}$| as predicted by galactic wind models. Our fitting method is based only on Poisson sampling from an evolutionary track and requires no binning of the data. We demonstrate its accuracy by testing against mock data, showing that it accurately recovers the input model across a broad range of sample sizes (20 ≤ N ≤ 2000) and measurement uncertainties (0.01 ≤ σ[α/Fe], σ[Fe/H] ≤ 0.5; |$0.02 \le \sigma _{\log _{10}(\text{age})} \le 1$|⁠). Due to the generic nature of our derivation, this likelihood function should be applicable to one-zone models of any parametrization and easily extensible to other astrophysical models which predict tracks in some observed space.

This study utilized polarization characteristics to explore the variations in beam split capacity among different sucrose solution concentrations, while also tracking the hydrolysis process of sucrose under acidic conditions. The paper further elucidates the scientific principles underlying these experimental phenomena. [ABSTRACT FROM AUTHOR]

The propagation of acoustic waves in the periodic structure of phononic crystals has energy band effects, and phononic crystals containing defects can form new defect modes in the original forbidden band. In this study, the omnidirectional transmission spectra of phononic crystals with and without defects in obliquely incident acoustic waves are calculated respectively by the transfer matrix method, and the defect modes caused by solid defects are found by comparative analysis. On this basis, the influence of the thickness and position of the defect layer on the transmittance of the defect state is studied in this study. The existence of defect modes caused by solid defects and their angle-dependent characteristics are verified by underwater acoustic transmission experiments. The experimental results show that there is a new transmission passband in the first Bragg forbidden band of the omnidirectional transmission spectrum of the defect-containing structure, and with the increase of the incident angle within a certain range, the frequency corresponding to this passband is shifted to the high frequency direction. This study improves the propagation characteristics of obliquely incident acoustic waves in one-dimensional phononic crystals containing defects, and provides a theoretical and experimental basis for the practical application of defect states.

In order to solve the difficult problem of complex analysis of the dynamic performance of steel-BFPC joint surface and establish its simulation model, the identification method of dynamic performance parameter of steel-BFPC joint surface was studied, the influence law of roughness and surface pressure on its dynamic performance was analyzed, and its neural network prediction model was established. The simulation analysis method was established by using equivalent spring-damping unit combined with finite element simulation software. In order to test the accuracy of parameter identification and simulation analysis method, a BFPC machine bed was designed, and its dynamic performance was measured experimentally first, and then finite element simulation was used to study the modal performance of BFPC bed with different spring-damping unit layouts and determine its optimal layout, and then determine the frequency response simulation performance of BFPC bed with optimal spring-damping unit layout. The maximum relative error of inherent frequency is 5.17%, and the maximum relative error of acceleration frequency response curve amplitude is 8.96%. The research results show that the identification method of dynamic performance parameters of steel-BFPC joint surface and its simulation analysis method are effective and accurate. The research conclusion provides a theoretical basis for steel-BFPC joint surface performance analysis and its virtual simulation. [ABSTRACT FROM AUTHOR]

Due to the composition complexity of traditional Chinese medicines (TCMs). the identification and clarification of the chemical components of TCMs plays a crucial role in the evaluation of safety and efficacy of their clinical use. In this work, an ultra-high performance liquid chromatography-quadrupole-electrostatic field Orbitrap mass spectrometry (UHPLC-Q-Orbitrap/MS) was used to analyze the chemical composition of the substance benchmark of Zhu Ye ShiGao decoction (ZSD), a widely used TCM formula. The UHPLC separation was performed on a SUPELCO C18 column (100 mm X 4.6 mm X 2.7 µm) with water (A) and acetonitrile (B) both containing 0.1% formic acid as mobile phases. The column temperature was 30 °C, and the injection volume was 5 μL. The gradient started with 5% B. and increased to 20% B at 5 min. to 40% B at 15 min, to 95%B at 25 min, dropped back down to 5% B at 27 min, and remained 5%B to 35 min with a flow rate of 0.5 mL/min. The molecular ions and fragment ions data obtained by HRMS in positive and negative ion modes were used to identify the components in the substance benchmark of ZSD by referring to the self-constructed database from the related literatures and the MS data collected from control products, and to study the MS fragmentation mechanism. A total of 121 compounds were identified. including 47 triterpenes. 34 flavonoids. 10 steroidal saponins, and 30 other compounds. Among them, the flavonoids are mainly from Lophatheri, Glycyrrhizae and Ophiopogonis, the saponins are mainly from Ginseng and Glycyrrhizae, and the alkaloids are mainly from Pinelliae. ZSD formula consists of 7 herbs, of which the components may be loss during the preparation of the substance benchmark. For example, the amino acids in Pinelliae was significantly reduced in the substance benchmark, and the wide- spread presence of steroidal saponins in Ophiopogonis was also converted during the preparation. In addition to the loss of components, components in different herbs may react with each another to produce new components during the preparation of the substance benchmark. These not only led to absence of identification of some well- known components in the herbs of ZSD, but also made it difficult to identify the newly produced compounds with high intensity of MS signals, requiring further study. Even so, however, the present work identified the chemical composition of the ZSD substance benchmark and explored the fragmentation pathways of the identified components by using UHPLC-Q-Otbitrap/MS, providing a good reference basis for quality control and the pharmacodynamics research of ZSD.

In order to predict the load of cutting coal and rock by picks, the time domain and frequency domain characteristics of the load when cutting coal and rock by picks with different axial inclinations are analyzed. Based on the experimental load data, the particle swarm optimization algorithm optimized by inertia weight is used to optimize and determine the error parameter γ and kernel function parameter of the least squares support vector machine ( LSSVM ), and a prediction method of three-way load of picks under axial inclination is given. The research results show that under different axial tilt conditions, the average correlation coefficient of the predicted three-way load is 0.837, and the maximum average error of the three-way load is 4.82 %, which has a strong correlation. The frequency components are mainly concentrated in the low frequency band of 0～5 Hz. The prediction is consistent with the overall change rule and amplitude fluctuation of the experimental load, which verifies the accuracy of the prediction method. The research results provide a reference for the calculation of the working load of different axially inclined picks on the drum end plate and blade, the reasonable arrangement of shearer picks and the adaptive cutting of coal and rock.
