随着装配式建筑的发展，由轻钢龙骨外覆各类蒙皮板组成的新型复合墙体已得到了广泛应用。然而，在平面外荷载作用下，蒙皮板与轻钢龙骨之间的界面将会产生显著的滑移效应从而降低墙体的平面外刚度而导致变形的增加。基于简化的组合梁界面剪切滑移理论，推导建立了轻钢龙骨-防火板复合墙体平面外均布荷载下弹性剪切滑移微分方程和蒙皮效应组合系数表达式。通过蒙皮效应组合系数对复合墙体截面刚度进行修正，进而得到墙体刚度、防火板和胶层应力的计算公式。最后结合静力堆载试验，对6块墙体的实测结果与理论以及折减刚度法结果进行对比，相比于折减刚度法，理论计算结果与试验结果更为接近，进而验证了所提公式的准确性。

目的比较常规体外受精（IVF）和卵胞质内单精子注射（ICSI）两种不同授精方式对解冻移植第六天（D6）囊胚患者妊娠结局的影响。方法回顾性队列研究分析中山大学附属第三医院生殖中心2018年1月至2020年4月期间解冻移植第六天囊胚移植患者的临床资料，按受精方式分为常规IVF组（446例）和ICSI受精组（200例）。按是否有第五天（D5）囊胚移植史，分为仅有D6囊胚冷冻及移植的患者，以及有D5囊胚移植史的患者。比较两组患者基本资料、囊胚质量及妊娠结局。结果IVF组和ICSI组患者BMI，不孕年限，基础FSH差异均无统计学意义（P > 0.05）。ICSI组患者年龄小于IVF组患者，原发性不孕的比例高于常规IVF组，获卵数和正常受精卵子数高于常规IVF受精组（P < 0.001）。常规IVF组五期和六期囊胚比例高于ICSI组（21.6 % vs. 3.14 %， P < 0.001）。ICSI组ICM评分为A级的囊胚高于IVF组（23.8 % vs. 14.3 %， P = 0.01）。ICSI组HCG阳性率和临床妊娠率均高于IVF组（65.5 % vs. 48.4 %， P < 0.001； 56 % vs. 41.3 %， P = 0.001），ICSI组胚胎种植率和活产率也高于常规IVF组（43.8 % vs. 30.9 %， P < 0.001； 43.0 % vs. 31.8 %， P = 0.006）。校正两组间年龄、获卵数等影响因素后，ICSI组临床妊娠率仍高于常规IVF组（OR：1.590， 95 % CI： 1.030， 2.455， P = 0.036）。ICSI组出生婴儿体质量低于IVF组（P = 0.016），早产率、性别比与分娩方式在两组间差异无统计学意义。结论ICSI受精的D6囊胚解冻移植后的临床妊娠率高于常规IVF受精的D6囊胚，活产率有升高的趋势，可能与IVF与ICSI病人导致囊胚发育慢的因素不同有关。ICSI受精的D6囊胚解冻移植后相对好的妊娠结局，可在一定程度上弥补ICSI周期囊胚发育相对较慢导致的妊娠结局的差异。

目的探讨以囊胚培养及解冻囊胚移植为主流时，移植解冻卵裂期胚胎的妊娠结局，评价冻存卵裂期胚胎的价值，以及影响解冻卵裂期胚胎移植妊娠率的因素。方法回顾性分析本中心2015年9月至2020年6月共1 607例解冻卵裂期胚胎移植的临床结局，根据是否行囊胚培养及是否有可用囊胚，分为3组，即无养囊组、养囊失败组、养囊成功组。分析3组人群的年龄、不孕年限、基础FSH、BMI、获卵数、D3优胚数等基本资料，以及使用logistic回归分析影响解冻卵裂期胚胎移植临床妊娠率的因素。结果解冻D3卵裂胚移植的总体临床妊娠率较低（35.2%，565/1 607），未养囊组随着女方年龄的增加妊娠率显著下降。养囊失败组例数较少（98例），妊娠组与未妊娠组间临床资料及胚胎发育情况差异无统计学意义。养囊成功但有移植囊胚失败史的病人，解冻卵裂胚的总体临床妊娠率高于其他两组，为46.9%，年龄、获卵数、D3优胚数、可用囊胚数、移植胚胎评分不影响此组妊娠率。与囊胚已解冻完相比，剩余冻存囊胚数≥1的妊娠率显著升高，OR 95%CI为3.789（2.088，6.877），P＜0.001。ICSI病人临床妊娠率略高于常规IVF病人，OR 95%CI为1.783（0.987，3.224），P=0.055。结论对于卵巢反应差无养囊的病人，临床妊娠率与年龄和胚胎质量有关；于养囊病人，即使养囊失败，或者移植囊胚失败（未妊娠），解冻卵裂胚胚胎移植仍有相当的临床妊娠机会。因此在养囊为主流的情况下，建议D3冻存部分卵裂期胚胎，可根据患者自身条件及中心的囊胚培养效率，选择一定数量及质量的卵裂期冻存。

均匀波带交换波带粒度固定,灵活性和可扩展性不足。文章提出一种新型多粒度光交叉连接结构,并在该结构的基础上提出一种FENBS（灵活可扩展的非均匀波带交换）算法。当路径重叠的业务较少时,分组成较小粒度波带;当路径重叠的业务较多时,分组成较大粒度波带,比均匀波带交换波带分组更灵活。使更多的业务容纳在波带内,节省了端口。仿真结果表明:FENBS算法比均匀粒度的BPHT（大业务优先的平衡路径路由波带分配）算法占用的端口更少。

Steel fiber has become a reinforcing material with increasing application demand in civil engineering, so the damage and fracture of steel fiber reinforced concrete (SFRC) is also a key problem that needs to be solved urgently in engineering. Based on the unified phase field theory and cohesion model proposed recently, a meso-finite element model of SFRC composed of steel fiber, aggregate, mortar and interface transition zone was established and verified by experiments. Under the conditions of uniaxial tension and three-point bending, the effects of factors such as steel fiber content and length, aggregate shape, and initial notch defects on the tensile and flexural properties of SFRC were investigated, and the mechanical properties and damage mechanism of SFRC were studied. The results show that the SFRC meso-finite element model based on the phase field damage model and cohesion model has good accuracy and reliability. The tensile strength of SFRC is greatly affected by the content of steel fiber, and the cost performance is higher at 2% content, which is 34. 2% higher than that at 0. 5% content. The influence of aggregate shape and steel fiber length is small. The bending strength of SFRC is greatly affected by the content of steel fiber and the cut depth. The addition of 0. 2%, 0. 35% and 0. 5% steel fiber increase the bearing capacity of SFRC cut beam by 20. 7%, 38. 9% and 63. 7%, respectively, compared with SFRC cut beam with a cut depth of 25 mm. The bearing capacity of SFRC beam with 40 mm and 55 mm incision depth decrease by 19. 9% and 39. 8%, respectively. It can be used as reference for steel fiber reinforced concrete engineering analysis and design. [ABSTRACT FROM AUTHOR]

Objective To investigate the predictive value of soluble growth-stimulated expressed gene 2 protein （sST2） in predicting sepsis-associated acute kidney injury （SA-AKI）. Methods From January 2020 to December 2023， a total of 395 sepsis patients with sepsis from the Emergency Department， Affiliated Hospital of Nantong University were enrolled in this retrospective observational study. These patients were further categorized into two groups: AKI group （114 cases） and non-AKI group （281 cases）. Clinical data and laboratory indicators were collected within 24 hours after admission. ROC curve analysis was used to evaluate the diagnostic ability of sST2 for SA-AKI. Logistic regression analysis was performed to assess independent risk factors for the development of SA-AKI. Concurrently， two predictive models for SA-AKI were constructed， and the predictive ability of sST2 for SA-AKI was assessed using the Area Under the Curve （AUC）， the Net Reclassification Index （NRI） and the Integrated Discrimination Improvement （IDI）. Results T The levels of sST2 were significantly higher in the AKI group compared to the non-AKI group （P < 0.001）. The AUC predicted by sST2 （0.839， 95% CI: 0.799 ~ 0.874） in sepsis patients with AKI was significantly superior to other laboratory indicators （P < 0.000 1）. An sST2 concen-tration greater than 85 ng/mL independently increased the risk for SA-AKI （OR: 14.315， 95% CI: 5.867 ~ 34.926， P < 0.001）. Incorporating sST2 into the prediction model substantially improved the AUC values （0.954 vs. 0.909， P < 0.000 1）， NRI（ 21.48%， 95% CI: 11.48% ~ 31.49%， P < 0.000 1） and IDI（ 8.62%， 95% CI: 5.75% ~ 11.49%， P < 0.000 1）. Conclusion sST2 has the potential to serve as a promising biomarker for prognosticating AKI in septic patients. [ABSTRACT FROM AUTHOR]

Objective Analyzing the applicability of pipeline simulation technology in energy measurement, and examine the deviation between simulation calculation results and actual pipeline measurement values. Methods Using a closed natural gas pipeline network with multiple gas sources will be as an example, a simulation model with functions for natural gas heat generation, pressure, and flow calculation was established. This model is based on the theoretical foundation of pipeline network simulation for energy measurement. Results The deviation between the simulation results of heat generation and the calculated values of the on-site chromatographic analyzer is within 0.3%, which meets the requirements of the maximum allowable error of assigned heat generation in GB/T 18603—2023 Technical requirement of measuring systems for natural gas. The deviation between the pressure simulation calculation result and the recorded value of the on-site pressure transmitter is within 1.0%, and the deviation between the flow simulation calculation result and the measured value of the on-site flow meter is within 2.0%. Conclusions The energy measurement technology based on pipeline simulation is a feasible method for assigning heat generation values to complex multi-gas source pipelines. This method can also be used for real-time tracking or verification of pipeline pressure, flow rate, and natural gas pipeline inventory. [ABSTRACT FROM AUTHOR]

With the ongoing depletion of surface and shallow mineral resources, future mining efforts must inevitably venture deeper. As mining depth increases, operations face a "three high and one disturbance" environment, severely affecting normal production activities. Therefore, pressure management has become an essential prerequisite for mine production. The study consolidates current research achievements in 3 areas, including basic theory, monitoring methods, and ground pressure management, to provide foundational guidance for practical mining operations. Basic theory explores the internal mechanical mechanisms of ground pressure activities through dynamic-static load combinations and temperature seepage stress multi-field coupling effects. Monitoring methods discuss the deployment of stress-strain monitoring systems and microseismic monitoring systems, where static stress-strain monitoring and dynamic real-time microseismic monitoring work in tandem to effectively monitor pressure activities during production. Pressure management measures cover pressure regulation methods and support systems, clarifying current issues in fundamental theories and prevention measures for deep mine pressure and guiding future research to promote intensive deep mining [ABSTRACT FROM AUTHOR]
