The novel shish-kebab-type liquid crystalline cross-conjugated （p-phenylene）s-poly（p-phenylenevinylene）s hybrid was synthesized through Gilch polymerization. Their structures and properties were characterized by NMR, GPC, DSC, X-ray diffraction and polarizing optical microscope （POM）. ^1H-NMR investigation of the polymers indicates that the shish-kebab-structure has a strong ability to suppress the structural defects in the polymers. The polymers are enantiotropic liquid crystals. The melting point （Tm） of the polymers decreases when the length of the alkoxy tails of the mesogenic units increases. The mesophase was identified by X-ray diffraction method. They showed not only a smectic LC phase, but also a strong green fluorescence in chloroform. The maximum absorption band of the ＂kebabs＂ of the two, 5-bis（4＇- alkoxyphenyl）benzene at 280 nm did not appear in absorption spectra of the polymers. The same phenomena were also observed in the fluorescence spectra. These results imply that the polymers have formed a cross-conjugated uniform structure and achieved an extended n-conjugation polymer.

Behcet disease （BD） is a chronic multisystem disease ＇that presents with recurrent oral and genital ulceration and recurrent uveitis. Vascular and cardiac thromboses are rare but life threatening complications. We report a case of right internal jugular vein and brachiocephalic vein thrombus and successive cardiac thrombosis, which was finally diagnosed with BD.

近场强震数据是地震观测的主要数据类型之一,但尚未广泛用于震源参数快速和常规测定.作者利用2017年8月8日九寨沟地震的近场强震数据,分别基于中国地震台网中心和美国地质调查局的定位结果,采用迭代反褶积和叠加(Iterative Deconvolution and Stacking,IDS)方法反演得到了两个破裂模型.反演结果显示,两个破裂模型除在时间上存在大约2.5 s的偏移外,在其他破裂特征上都极其相似,表明强震数据反演并不严重依赖地震定位结果.破裂过程大约持续8～10 s,释放的地震矩在6.9×1018Nm左右,对应的矩震级约为MW6.5.走向方向上,破裂覆盖了震中西北15 km至震中东南10 km的区域,整体表现为不对称的双侧破裂模式,其中西北方向的破裂略占优势.深度方向上,主要破裂集中在0～10 km的较浅区域.这些特征与目前的地震学和大地测量学结果基本一致,表明在当前的数据条件下,即使定位结果存在不确定性,通过反演强震数据也能够独立可靠地确定中强地震的破裂过程.特别地,未来强震数据的数据质量和获取效率得到进一步改进和提升后,这一工作有望成为震后快速确定破裂过程的主要方式之一,在震后应急工作中发挥积极作用.

The burgeoning market for lithium-ion batteries has stimulated a growing need for more reliable battery performance monitoring. Accurate state-of-health(SOH) estimation is critical for ensuring battery operational performance. Despite numerous data-driven methods reported in existing research for battery SOH estimation, these methods often exhibit inconsistent performance across different application scenarios. To address this issue and overcome the performance limitations of individual data-driven models,integrating multiple models for SOH estimation has received considerable attention. Ensemble learning(EL) typically leverages the strengths of multiple base models to achieve more robust and accurate outputs. However, the lack of a clear review of current research hinders the further development of ensemble methods in SOH estimation. Therefore, this paper comprehensively reviews multi-model ensemble learning methods for battery SOH estimation. First, existing ensemble methods are systematically categorized into 6 classes based on their combination strategies. Different realizations and underlying connections are meticulously analyzed for each category of EL methods, highlighting distinctions, innovations, and typical applications. Subsequently, these ensemble methods are comprehensively compared in terms of base models, combination strategies, and publication trends. Evaluations across 6 dimensions underscore the outstanding performance of stacking-based ensemble methods. Following this, these ensemble methods are further inspected from the perspectives of weighted ensemble and diversity, aiming to inspire potential approaches for enhancing ensemble performance. Moreover, addressing challenges such as base model selection, measuring model robustness and uncertainty, and interpretability of ensemble models in practical applications is emphasized. Finally, future research prospects are outlined, specifically noting that deep learning ensemble is poised to advance ens
