This paper introduces the research on the inductance‐capacitor‐capacitor‐inductance grid‐connected inverter using active disturbance rejection and grid voltage feedforward coordinated control technology. The pade approximation is performed on the inductance‐capacitor‐capacitor‐inductance filter to derive the first‐order discretization mathematical ...

新型压疮防护系统对压疮高危风险病人的防护作用的研究 [PDF]
[目的]探讨新型压疮防护系统对压疮高风险病人的压疮预防性作用。[方法]选取吉林省人民医院2015年2月—2017年2月具有压疮高风险(Braden评分〈12分)的住院病人126例,首先给予常规压疮预防护理45例作为对照组,后81例病人给予新型压疮防护系统作为预防性的措施为实验组,通过观察两组的皮肤情况,统计病人的压疮发生率和评价病人的舒适度。[结果]实验组病人住院第2天、住院第7天压疮发生率低于对照组,差异有统计学意义。[结论]新型压疮防护系统能降低压疮高风险病人的压疮发生率。吉林省卫生计生委课题,编号:

在当前“双碳”目标的背景下,中国大力提倡能源转型,可再生能源发展迅速,其反调峰增大了系统的调峰压力。抽水蓄能电站作为重要调峰资源,是解决上述问题的有效手段之一,综合量化评估其在大规模风光并网下的效能,是对抽蓄电站的建设投资、运营设计和经济优化等工作提供科学决策的前提。为此,首先分析实际系统运行中抽蓄电站效能发挥的典型场景,并根据抽蓄电站的特性从不同维度建立了电站效能评价指标。然后采用模糊综合评价法构建了一套综合效能量化评估体系,运用改进层次分析法-CRITIC法的综合赋权法对各层指标赋权 ...

Trace water transforms from an impurity to a design handle for ternary organic solar cells. During solvent evaporation, minimal amounts organize transient hydrogen‐bonding networks that steer component migration and set the morphology. The mechanism enables reproducible morphology locking and identifies a practical co‐solvent threshold near H2O:CF = 0 ...

IR‐induced dysbiosis depletes P. coprophilus and its metabolite 6‐methyluracil, leading to disinhibition of the IDO1‐Kyn‐AHR axis. This results in sustained fibroblast activation and collagen deposition, driving radiation induced intestinal fibrosis. ABSTRACT Therapeutic options for radiation‐induced intestinal fibrosis (RIF) remain limited. This study

This study presents a DNA hydrogel‐mediated delivery system, in which ginsenoside (GS) molecules are incorporated into small extracellular vesicles (sEV) secreted by mesenchymal stem cells (MSCs) and the formed complexes are then anchored in DNA hydrogels via aptamer‐CD63 affinity as “GS/sEV@DNAgels”, to improve diabetic wound repair.

Worm‐Inspired Soft Robots With Modular Outfit‐Changing for Intelligent Multienvironment Adaptation
This study proposes a worm‐inspired soft robot capable of locomotion across multiple environments through a modular “outfit‐changing” strategy. The robot integrates pneumatically actuated peristaltic segments with interchangeable external modules, enabling efficient motion on ground surfaces, within pipelines, through granular media, and underwater ...
