A 2.5-dimensional dynamic structural color based on nanogratings of heterogeneous materials was proposed by interweaving a pH-responsive hydrogel with IP-L *** nanogrid structures exhibit brilliant tuneable structural color, high sensitivity, and ultrafast recovery speeds in response to *** 4D printing-based grayscale design approach was proposed for the patterned encoding and array printing of dynamic structural colors, promoting their application in patterned printing, information encryption, and microfluidic chip sensing. Dynamic structural colors can change in response to different environmental stimuli. This ability remains effective even when the size of the species responsible for the structural color is reduced to a few micrometers, providing a promising sensing mechanism for solving microenvironmental sensing problems in micro-robotics and microfluidics. However, the lack of dynamic structural colors that can encode rapidly, easily integrate, and accurately reflect changes in physical quantities hinders their use in microscale sensing applications. Herein, we present a 2.5-dimensional dynamic structural color based on nanogratings of heterogeneous materials, which were obtained by interweaving a pH-responsive hydrogel with an IP-L photoresist. Transverse gratings printed with pH-responsive hydrogels elongated the period of longitudinal grating in the swollen state, resulting in pH-tuned structural colors at a 45 degrees incidence. Moreover, the patterned encoding and array printing of dynamic structural colors were achieved using grayscale stripe images to accurately encode the periods and heights of the nanogrid structures. Overall, dynamic structural color networks exhibit promising potential for applications in information encryption and in situ sensing for microfluidic chips.

Sporadic E(Es)layers in the ionosphere are characterized by intense plasma irregularities in the E region at altitudes of 90-130 *** they can significantly influence radio communications and navigation systems,accurate forecasting of Es layers is crucial for ensuring the precision and dependability of navigation satellite *** this study,we present Es predictions made by an empirical model and by a deep learning model,and analyze their differences comprehensively by comparing the model predictions to satellite RO measurements and ground-based ionosonde *** deep learning model exhibited significantly better performance,as indicated by its high coefficient of correlation(r=0.87)with RO observations and predictions,than did the empirical model(r=0.53).This study highlights the importance of integrating artificial intelligence technology into ionosphere modelling generally,and into predicting Es layer occurrences and characteristics,in particular.

目的观察外科腹腔感染患者血清降钙素原(PCT)、肿瘤坏死因子-α(TNF-α)、C-反应蛋白(CRP)和白细胞介素6(IL-6)的水平变化与感染程度的相关性,为临床指导抗菌药物应用提供依据。方法选择医院普通外科2012年11月-2016年12月收治的69例外科腹腔感染和24例非腹腔感染患者,依据腹腔感染范围不同,分为无感染组24例,局部感染组38例和弥漫性感染组31例,检测患者入院时及抗感染治疗第3天的体温(T)、白细胞(WBC)、中性粒细胞百分率(N%)、血清PCT、TNF-α、CRP和IL-6的水平,分析其与WBC的相关性。结果弥漫性感染组、局部感染组入院时T、WBC、N%、CRP、TNF-α和IL-6表达显著高于无感染组(P<0.05);弥漫性腹腔感染组TNF-α和IL-6表达高于局部感染组;弥漫性感染组与局部感染组、无感染组比较,PCT表达明显升高;抗感染治疗3天后,两组感染患者T、WBC、N%、CRP、TNF-α、PCT和IL-6表达较入院时均明显下降(P<0.05),而弥漫性感染组TNF-α、PCT和IL-6水平仍高于局部感染组。PCT、TNF-α、CRP、IL-6与WBC均呈正相关。结论临床检测血清PCT、TNF-α、CRP和IL-6均有助于鉴别是否存在外科腹腔感染,与CRP和WBC相比,PCT、TNF-α和IL-6检测更有助于评估腹腔感染严重程度,对抗菌药物应用有一定的指导作用。

This paper reports the results of an experimental study on the liquid phase characteristics of the biodiesel and diesel discharged from an equilateral triangular orifice and a circular orifice under different injection conditions by Mie-scattering *** results revealed that the biodiesel liquid penetration length was longer than that of diesel under the same injection *** addition,the increase of the chamber pressure was expected to enhance the interaction between air and fuel,resulting in the acceleration of the liquid phase breakup ***,with increasing chamber temperature,the liquid penetration of biodiesel was reduced less than that of *** was due to the high surface tension and viscosity of biodiesel which inhibited the chamber air entrainment and suppressed the liquid breakup ***,the higher probability of shorter diesel liquid penetration length indicated better air-fuel mixing than that of ***,the triangular orifice liquid length was shorter than that of the circular *** the stabilized liquid cone angle from the circular orifice was larger than that from the triangular orifice,indicating that using an equilateral triangular orifice has the potential to improve the air-fuel mixing process.

Ovarian endometrioma（OE）, also known as “chocolate cysts,” is a cystic mass that develops in the ovaries due to endometriosis and is a common gynecological condition characterized by the growth of endometrial tissue outside the uterus, leading to symptoms such as dysmenorrhea, pelvic pain, and infertility. However, the precise molecular and cellular mechanisms driving this pathophysiology remain largely unknown, posing challenges for diagnosis and treatment. Here, we employed integrated single-cell transcriptomic profiling of over 52,000 individual cells from endometrial tissues of OE patients and healthy donors and identified twelve major cell populations. We identified notable alterations in cell type-specific proportions and molecular signatures associated with OE. Notably, the activation of IGFBP5+macrophages with pro-inflammatory properties, NK cell exhaustion, and aberrant proliferation of IQCG+and KLF2+epithelium are key features and may be the potential mechanisms underlying the pathogenesis of OE. Collectively, our data contribute to a better understanding of OE at the single cell level and may pave the way for the development of novel therapeutic strategies.

针对现有的特征提取方法忽略文本局部和全局联系的问题，提出了基于多尺度特征提取的层次多标签文本分类方法。首先，设计了多尺度特征提取模块，对不同尺度特征进行捕捉，更好地表示文本语义。其次，将层次特征嵌入文本表示中，得到具有标签特征的文本语义表示。最后，在标签层次结构的指导下对输入文本构建正负样本，进行对比学习，提高分类效果。在WOS、RCV1-V2、NYT和AAPD数据集上进行对比实验，结果表明，所提模型在评价指标上表现出色，超过了其他主流模型。此外，针对层次分类提出层次Micro-F1和层次Macro-F1指标，并对模型效果进行了评价。
