Channel prediction is an effective approach for reducing the feedback or estimation overhead in massive multi-input multi-output (m-MIMO) systems. However, existing channel prediction methods lack precision due to model mismatch errors or network generalization issues. Large language models (LLMs) have demonstrated powerful modeling and generalization abilities, and have been successfully applied to cross-modal tasks, including the time series analysis. Leveraging the expressive power of LLMs, we propose a pre-trained LLM-empowered channel prediction(LLM4CP)method to predict the future downlink channel state information (CSI) sequence based on the historical uplink CSI sequence. We fine-tune the network while freezing most of the parameters of the pre-trained LLM for better cross-modality knowledge transfer. To bridge the gap between the channel data and the feature space of the LLM,preprocessor, embedding, and output modules are specifically tailored by taking into account unique channel characteristics. Simulations validate that the proposed method achieves state-of-the-art (SOTA) prediction performance on full-sample, few-shot, and generalization tests with low training and inference costs.

Dear Editor,Unlike previous outbreaks of the mpox(previously known as monkeypox),which were localized in Africa and resulted in small numbers of infections due to limited human-to-human transmission,the current outbreak beginning in May 2022,has spread rapidly primarily through human-to-human transmission in non-endemic countries(Gong et al.,2022).As of 27 Sep 2023,115 countries and regions have reported cases of mpox to the World Health Organization(WHO),bringing the total number of confirmed cases to 90,618 including 125 *** the number of new cases has decreased in most WHO regions in the second half of 2022,the curves reveal a long outbreak tail in different subregions of the *** worrying,106 mpox cases were reported in the mainland of China in June 2023.

A study was conducted on the effect of time delay and structural parameters on the vibration reduction of a time delayed coupled negative stiffness dynamic absorber in nonlinear vibration reduction systems. Taking dynamic absorbers with different structural and control parameters as examples, the effects of third-order nonlinear coefficients, time-delay control parameters, and negative stiffness coefficients on reducing the replication of the main system were discussed. The nonlinear dynamic absorber has a very good vibration reduction effect at the resonance point of the main system and a nearby area, and when 1 increases to a certain level, the stable region of the system continues to increase. The amplitude curve of the main system of a nonlinear dynamic absorber will generate Hop bifurcation and saddle node bifurcation in the region far from the resonance point, resulting in almost periodic motion and jumping phenomena in the system. For nonlinear dynamic absorbers with determined structural parameters, time-delay feedback control can be adopted to control the amplitude of the main system. For different negative stiffness coefficients, there exists a minimum damping point for the amplitude of the main system under the determined system structural parameters and time-delay feedback control parameters.

先秦纵横家子书《阙子》已佚,清代辑佚学家马国翰、顾观光均有辑本。对现存佚文考辨后可知,由于失注出处且多从文多者补正,多条佚文存在择取欠精的疏陋,此外还可补辑出新佚文。《阙子》现存佚文均为人物寓言,题材丰富且颇具艺术价值。其寓言不乏对《庄子》的继承,如多以钓说理、多贬低宋人并持有相似的言辞观。阙子融合了以庄子为代表的“空语型”和以孟子、韩非子为代表的“事实型”两种战国寓言题材,还曾与庄子、荀子取用同一寓言素材,其所处时代大致为战国后期。《阙子》寓言流传甚广,被后世频繁征引,足见其寓言之精妙,其流传方式主要有三种:引用事典佐证、化用事典说理、对事典进行改编。

孕妇年龄28岁,身高164 cm,体质量79 kg。因"停经40+3周,阴道少量见红3 h余"入院。既往焦虑症病史3年余,口服帕罗西汀治疗,孕期停药。入院诊断:妊娠状态;妊娠期体质量增加过度;焦虑症。孕妇待产期间要求行分娩镇痛。取左侧卧位,使用钢丝加强型腰硬联合包经L3,4正中法穿刺,至硬膜外腔后,向头侧置入硬膜外导管4 cm并固定,操作过程顺利。注射1.5%利多卡因试验剂量3 ml,观察5 min无不适后,予0.1%罗哌卡因复合0.5μg/ml舒芬太尼行硬膜外分娩镇痛,首剂量15 ml,持续剂量6 ml/h,PCA剂量6 ml,锁定时间30 min。孕妇镇痛效果满意,顺利分娩。侧卧位欲拔除硬膜外导管时,发现阻力大,拔管困难。上级医师到场后多次调整体位,并嘱产妇做弯腰、挺腹动作,辅以导管旁局部浸润麻醉、按摩等措施,仍未成功。为避免暴力拔管致导管离断,暂予导管处消毒包扎固定。

针对折叠翼飞行器(FWV)模型误差和抗扰动能力较差及自抗扰控制器(ADRC)人工参数整定难的问题,提出一种基于莱维飞行的改进平衡优化(LEO)算法。给出典型FWV动力学模型,基于ADRC结构设计一种FWV的姿态控制器;在此基础上用所提算法整定了ADRC参数,并从控制性能和抗干扰的角度对经参数优化后的ADRC和传统ADRC进行仿真对比;将所提算法与经典平衡优化算法、粒子群优化(PSO)算法等进行仿真对比。仿真结果表明:所提算法优化的控制器能提高FWV的控制精度和扰动抑制性能,验证了所提算法在解决ADRC参数优化问题时的优越性。对搭载优化后ADRC的样机进行实飞验证,结果表明:在风扰之下,FWV样机仍具有较好的飞行性能指标,进一步验证了所提算法优化的ADRC对FWV抗扰能力的提升。
