背景食管胃底静脉曲张破裂出血(EGVB)是肝硬化常见且凶险的并发症之一,而EGVB能否影响肝硬化患者1年的死亡结局尚不完全清楚。目的探讨EGVB对肝硬化患者1年死亡结局的影响及相关因素分析,为肝硬化患者的随访提供依据。方法选取2015年1月至2021年5月在南华大学附属长沙中心医院就诊的肝硬化患者,根据患者就诊时有无合并EGVB分为EGVB组和未出血组,并对患者进行常规随访,随访终点为患者因肝硬化死亡或1年随访时间结束。采用Logistic回归分析筛选肝硬化患者1年死亡结局的影响因素,通过1∶2倾向性得分匹配(PSM)均衡混杂因素,利用Logistic回归分析探讨EGVB组和未出血组1年死亡结局的影响因素。结果共纳入肝硬化患者812例,其中EGVB组158例(19.5%),1年死亡率为13.3%(21/158);未出血组654例(80.5%),1年死亡率为13.9%(91/654),两组患者1年死亡率比较,差异无统计学意义(P>0.05)。匹配前多因素Logistic回归分析结果显示,血清钠[OR=0.95,95%CI(0.90,0.99)]、白蛋白[OR=0.95,95%CI(0.91,0.99)]水平升高是肝硬化患者1年死亡的保护因素(P0.05)。匹配后多因素Logistic回归分析结果表明,尿素氮水平升高[OR=1.15,95%CI(1.02,1.29)]是EGVB组患者1年死亡的独立危险因素(P<0.05),年龄增高[OR=1.09,95%CI(1.04,1.14)]、中性粒细胞计数/淋巴细胞计数(NLR)水平升高[OR=1.09,95%CI(1.00,1.18)]是未出血组患者1年死亡的独立危险因素(P<0.05)。结论EGVB事件发生与否对肝硬化患者1年死亡率无显著影响,但两组患者1年死亡结局的危险因素存在差异,EGVB组患者1年死亡的独立危险因素为尿素氮水平升高,而未出血组患者1年死亡的独立危险因素为年龄增高和NLR水平升高,这为肝硬化患者的临床随访提供了新的参考。

To date, there has been no report on fast-charging and Ahlevel sodium-ion batteries (SIBs) by utilizing thick hard carbon anodes that demonstrate prolonged cycling life and high areal capacity at high rates. Further, the relationship among the complex structure of hard carbon, storage mechanism, and fastcharging performance in alkali-metal ion batteries has been a subject of ongoing debate [1,2].

Dear Editor,This letter presents a joint probabilistic scheduling and resource allocation method(PSRA) for 5G-based wireless networked control systems(WNCSs). As a control-aware optimization method, PSRA minimizes the linear quadratic Gaussian(LQG) control cost of WNCSs by optimizing the activation probability of subsystems, the number of uplink repetitions, and the durations of uplink and downlink phases. Simulation results show that PSRA achieves smaller LQG control costs than existing works.

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

Lead-halide perovskite nanoparticles（LHP NPs） are highly promising materials for next-generation displays and solid-state lighting due to their exceptional optical properties. However, their inherent instability presents a significant challenge. Recent advances have demonstrated that optoelectronic devices based on monolayer nanoparticle films exhibit both high luminescence efficiency and long-term *** research demonstrates that mobility limitations and anisotropic alignments in CsPbBr3nanocube monolayer films are key to their stabilization, hindering spontaneous growth through face-to-face fusion and resulting in the formation of connecting necks in a diagonal direction. Introducing laser irradiation confirmed this by significantly accelerating nanocubes growth, increasing mobility, and enhancing local structural ordering, leading to larger and more regularly shaped nanosheets. Fourier transform infrared spectroscopy and energy dispersive spectroscopy line-scan analyses indicated that laser irradiation did not disrupt the ligand structure. Transmission electron microscopy and correlative cathodoluminescence electron microscopy revealed the effects of post-growth and heterogeneous structures, including enhanced luminescence and inhomogeneous intensity in the nanosheets. These findings deepen the understanding of the post-growth mechanism of monolayer nanoparticles and the structure-emission correlation and highlight the unique role of laser irradiation in directing the formation of well-defined and regular nanostructures.

The central nervous system, information integration center of the body, is mainly composed of neurons and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be u
