Journal of Geoscience and Environment Protection 2024年第9期12卷 152-166页

作者： Qinghai Wu Xiaofeng Yang Jun Liu Ruiqi Wang quanyou fu College of Nuclear Technology and Automation Engineering Chengdu University of Technology Chengdu China

To optimize the self-organization network, self-adaptation, real-time monitoring, remote management capability, and equipment reuse level of the meteorological station supporting the portable groundwater circulation wells, and to provide real-time and effective technical services and environmental data support for groundwater remediation, a real-time monitoring system design of the meteorological station supporting the portable groundwater circulation wells based on the existing equipment is proposed. A variety of environmental element information is collected and transmitted to the embedded web server by the intelligent weather transmitter, and then processed by the algorithm and stored internally, displayed locally, and published on the web. The system monitoring algorithm and user interface are designed in the CNWSCADA development environment to realize real-time processing and analysis of environmental data and monitoring, control, management, and maintenance of the system status. The PLC-controlled photovoltaic power generating panels and lithium battery packs are in line with the concept of energy saving and emission reduction, and at the same time, as an emergency power supply to guarantee the safety of equipment and data when the utility power fails to meet the requirements. The experiment proves that the system has the characteristics of remote control, real-time interaction, simple station deployment, reliable operation, convenient maintenance, and green environment protection, which is conducive to improving the comprehensive utilization efficiency of various types of environmental information and providing reliable data support, theoretical basis and guidance suggestions for the research of groundwater remediation technology and its disciplines, and the research and development of the movable groundwater cycling well monitoring system.

背景:如何既为大面积深度烧伤患者瘢痕整形修复提供足够的皮源,又能避免术区创面瘢痕的再次增生,一直是烧伤与创面修复研究的重要课题。目的:观察人工真皮联合自体瘢痕表皮复合移植在大面积烧伤后瘢痕整复中的临床应用效果。方法:回顾性分析2021年1月至2023年1月在蚌埠医学院附属蚌埠第三人民医院接受手术治疗的大面积烧伤后瘢痕增生、挛缩畸形患者的病历资料,共纳入73例,按照治疗方法分为3组:A组(n=21)接受人工真皮联合自体瘢痕表皮移植治疗;B组(n=27)接受功能部位瘢痕松解后移植自体瘢痕表皮治疗;C组(n=25)接受功能部位瘢痕松解后移植自体中厚皮治疗。记录3组患者受皮区皮片存活及感染情况,受皮区及供皮区创面愈合时间;通过温哥华瘢痕量表(VSS)、日常生活活动能力(ADL)评定3组患者受皮区、供皮区瘢痕情况及受皮区功能恢复情况。结果与结论:①B组患者皮片感染率低于A、C组(P<0.05),皮片存活优级率高于A、C组(P<0.05);②A组患者受皮区创面完全愈合时间长于B、C组(P<0.05),C组患者受皮区创面完全愈合时间长于B组(P<0.05);C组患者供皮区完全愈合时间长于A、B组(P<0.05);③B组患者术后12个月受皮区温哥华瘢痕量表评分高于A、C组(P<0.05),C组患者术后6,12个月供皮区温哥华瘢痕量表评分高于A、B组(P<0.05);A、C组患者术后12个月日常生活活动能力量表评估优级高于B组(P<0.05);④结果显示,应用人工真皮与自体瘢痕表皮复合移植治疗大面积烧伤后瘢痕挛缩,既能达到与中厚皮移植同样的效果,又能避免供皮区术后瘢痕的再次增生,可缩短供皮区创面愈合时间,相较于单纯移植瘢痕表皮治疗有明显优势。

利用南极半岛(D1-7)和南奥克尼群岛附近海域(D5-6)海洋沉积物有机质的分子生物标志物中所隐含的生态学关系,将重建的浮游生物生产力和种群结构变化与生物泵(BP)/微型生物碳泵(MCP)以及海洋碳汇和储碳效率联系起来研究。柱样沉积物中的一系列分子生物标志物在近百年里发生显著变化,上层海洋浮游生物生产力/群落结构与沉积碳库储量存在较大的时空演变,实际上均与全球气候变化相联系。研究结果如下:(1)从生物标志化合物正构烷烃分子组合特征和色谱图峰型、主峰碳(MH)、轻烃/重烃(L/H)、菌藻类-(nC_(15)+nC_(17)+nC_(19))、大型浮游植物-(nC_(21)+nC_(23)+nC_(25))和碳优势指数-(CPI)来看,沉积碳源主要是海源生物碳,海洋生物是固碳与储碳的天然碳汇。(2)D5-6柱样的有机质高富集,主要受海洋上层水体较高初级生产力、高沉积速率(平均为0.19 cm/a)、水深较浅(385 m)和还原性沉积环境(Pr/Ph值平均为0.95)这些均有利于颗粒有机碳(POC)通过BP过程从海洋表面输送到深海,快速埋藏和储存;而D1-7柱样因水深大(1 100 m)和沉积速率低(0.07 cm/a),含碳化合物沉降过程中发生降解,又被环境氧化降解(Pr/Ph值平均为1.22),二者均不利于沉积物储碳,但相比之下控制沉积物碳保存重要的因素可能是沉积速率。(3)近百年来南极半岛附近海域和南奥克尼群岛浮游动物总量、浮游植物初级生产力、硅藻和甲藻生物量趋于上升,而颗石藻生物量和所占比例呈减少趋势(南极半岛附近海域更明显),说明钙质生物泵作用在逐年下降,而硅藻主导的硅质泵作用在不断加强,这两个过程的相对强度在很大程度上决定了由生物泵结构(硅质泵/钙质泵)和效率、及其向海洋沉积物输送有机碳和无机碳的比例大小。(4)2个柱样的分子生物标志物变化趋势在整体上具有一定的可比性,均有明显的阶段性,在年代际突变后(1972年),受到显著影响的是南奥克尼群岛海域浮游动物总量从(5~6 cm)1982年开始发生明显增加,特别在1997年和2012年期间浮游动物总量开始剧增,意味着在全球变暖背景下浮游生物群落结构发生快速变化,浮游植物初级生产的降低和浮游动物总量的剧增,二者变异使得生物泵强度(增强/削弱)变化存在很大的不确定性。(5)相比之下,近百年来南极半岛附近海域浮游植物生产力/硅藻甲藻生物量逐渐提高,而微生物生产力/古菌生物量逐渐降低,意味着微生物固碳强度减弱,即MCP储碳效率在降低,揭示了全球变暖对海域浮游生物生产力/生物量的增减起到关键作用,而浮游生物群落生物量和组成特征直接影响南极海洋BP中上层水体有机碳的流动和MCP水柱固碳效率的强弱,作为全球海洋最大碳汇的南极,其储碳能力可能正在降低。

A Tutorial on Quantized Feedback Control

引用

IEEE/CAA Journal of Automatica Sinica 2024年第1期11卷 5-17页

作者： Minyue fu IEEE the School of System Design and Intelligent Manufacturing Shenzhen Key Laboratory of Control Theory and Intelligent Systems and Centre for Control Science and TechnologySouthern University of Science and TechnologyShenzhen 518055China

In this tutorial paper, we explore the field of quantized feedback control, which has gained significant attention due to the growing prevalence of networked control systems. These systems require the transmission of feedback information, such as measurements and control signals, over digital networks, presenting novel challenges in estimation and control design. Our examination encompasses various topics, including the minimal information needed for effective feedback control, the design of quantizers, strategies for quantized control design and estimation,achieving consensus control with quantized data, and the pursuit of high-precision tracking using quantized measurements.

Dynamics of 2×2 matrix non-Hermitian quantum systems on Bloch sphere

引用

Communications in Theoretical Physics 2024年第4期76卷 66-71页

作者： Libin fu Graduate School of China Academy of Engineering Physics Beijing 100193China

By casting evolution to the Bloch sphere, the dynamics of 2 × 2 matrix non-Hermitian systems are investigated in detail. This investigation reveals that there are four kinds of dynamical modes for such systems. The different modes are classified by different kinds of fixed points, namely,the elliptic point, spiral point, critical node, and degenerate point. The Hermitian systems and the unbroken PT non-Hermitian cases belong to the category with elliptic points. The degenerate point just corresponds to the systems with exceptional point(EP). The topological properties of the fixed point are also discussed. It is interesting that the topological charge for the degenerate point is two, while the others are one.
