Continuous-variable quantum key distribution based on photon addition operation

引用

Chinese Physics B 2021年第6期30卷 126-132页

作者： Xiao-Ting Chen lu-ping zhang Shou-Kang Chang Huan zhang Li-Yun Hu Center for Quantum Science and Technology Jiangxi Normal UniversityNanchang 330022China Key Laboratory of Optoelectronic and Telecommunication Jiangxi Normal UniversityNanchang 330022China

It is shown that the non-Gaussian operations can not only be used to prepare the nonclassical states, but also to improve the entanglement degree between Gaussian states. Thus these operations are naturally considered to enhance the performance of continuous variable quantum key distribution(CVQKD), in which the non-Gaussian operations are usually placed on the right-side of the entangled source. Here we propose another scheme for further improving the performance of CVQKD with the entangled-based scheme by operating photon-addition operation on the left-side of the entangled *** is found that the photon-addition operation on the left-side presents both higher success probability and better secure key rate and transmission distance than the photon subtraction on the right-side, although they share the same maximal tolerable noise. In addition, compared to both photon subtraction and photon addition on the right-side, our scheme shows the best performance and the photon addition on the right-side is the worst.

Feature Matching via Topology-Aware Graph Interaction Model

IEEE/CAA Journal of Automatica Sinica 2024年第1期11卷 113-130页

作者： Yifan lu Jiayi Ma Xiaoguang Mei Jun Huang Xiao-ping zhang the Electronic Information School Wuhan UniversityWuhan 430072China IEEE Tsinghua Berkeley Shenzhen Institute Shenzhen 518071China the Department of Electrical Computer and Biomedical EngineeringToronto Metropolitan UniversityToronto ON M5B 2K3Canada

Feature matching plays a key role in computer vision. However, due to the limitations of the descriptors, the putative matches are inevitably contaminated by massive *** paper attempts to tackle the outlier filtering problem from two aspects. First, a robust and efficient graph interaction model,is proposed, with the assumption that matches are correlated with each other rather than independently distributed. To this end, we construct a graph based on the local relationships of matches and formulate the outlier filtering task as a binary labeling energy minimization problem, where the pairwise term encodes the interaction between matches. We further show that this formulation can be solved globally by graph cut algorithm. Our new formulation always improves the performance of previous localitybased method without noticeable deterioration in processing time,adding a few milliseconds. Second, to construct a better graph structure, a robust and geometrically meaningful topology-aware relationship is developed to capture the topology relationship between matches. The two components in sum lead to topology interaction matching(TIM), an effective and efficient method for outlier filtering. Extensive experiments on several large and diverse datasets for multiple vision tasks including general feature matching, as well as relative pose estimation, homography and fundamental matrix estimation, loop-closure detection, and multi-modal image matching, demonstrate that our TIM is more competitive than current state-of-the-art methods, in terms of generality, efficiency, and effectiveness. The source code is publicly available at http://***/Yifanlu2000/TIM.

目的探究白细胞参数水平对急性胰腺炎(AP)早期严重程度及临床转归的预测价值。方法选取2022年1月—2022年12月甘肃省人民医院急诊科收治住院的AP患者152例为研究对象,根据患者病情严重程度分为轻症胰腺炎(MAP)组75例、复杂性急性胰腺炎(CAP)组77例;根据患者28 d内生存情况分为生存组137例和死亡组15例。另纳入80名健康体检者(设为对照组)作对照;采用受试者工作特征(ROC)曲线探究白细胞参数对AP患者早期严重程度及临床转归的预测价值。结果与对照组相比MAP组与CAP组除中性粒细胞细胞大小(NE-FSC)、单核细胞细胞大小(MO-Z)参数外,均具有统计学意义(P<0.05)。白细胞计数(WBC)、幼稚粒细胞百分比(IG)、中性粒细胞前向散射光强度分布宽度(NE-WX)、中性粒细胞侧向散射光强度分布宽度(NEWY)对AP严重程度诊断效能较优,将NE-WX、NE-WY进行联合诊断,其敏感性、阴性预测值均高于单一检测。相关性分析显示,WBC、中性粒细胞与淋巴细胞的比值(NLR)、NE-WX、NE-WY、淋巴细胞前向散射光强度分布宽度(LY-WX)水平与AP严重程度呈正相关(P<0.05)。白细胞参数预测CAP患者死亡的ROC曲线结果显示NE-WX、IG灵敏度、特异度较传统指标WBC、NLR有更高的预测价值。结论白细胞参数NE-WX、NE-WY、IG最终可能被纳入AP严重程度及临床转归的预测系统标志物中。

Surgical techniques to prevent delayed gastric emptying after pancreaticoduodenectomy

引用

Hepatobiliary & Pancreatic Diseases International 2024年第5期23卷 449-457页

作者： Peng Duan lu Sun Kai Kou Xin-Rui Li ping zhang Department of Hepatobiliary and Pancreatic Surgery General Surgery Centerthe First Hospital of Jilin UniversityChangchun 130021China Department of Dental Implantology Hospital of StomatologyJilin UniversityChangchun 130021China

Background: Delayed gastric emptying(DGE) is one of the most common complications after pancreaticoduodenectomy(PD). DGE represents impaired gastric motility without significant mechanical obstruction and is associated with an increased length of hospital stay, increased healthcare costs, and a high readmission rate. We reviewed published studies on various technical modifications to reduce the incidence of DGE. Data sources: Studies were identified by searching Pub Med for relevant articles published up to December 2022. The following search terms were used: “pancreaticoduodenectomy”, “pancreaticojejunostomy”, “pancreaticogastrostomy”, “gastric emptying”, “gastroparesis” and “postoperative complications”. The search was limited to English publications. Additional articles were identified by a manual search of references from key articles. Results: In recent years, various surgical procedures and techniques have been explored to reduce the incidence of DGE. Pyloric resection, Billroth II reconstruction, Braun's enteroenterostomy, and antecolic reconstruction may be associated with a decreased incidence of DGE, but more high-powered studies are needed in the future. Neither laparoscopic nor robotic surgery has demonstrated superiority in preventing DGE, and the use of staplers is controversial regarding whether they can reduce the incidence of DGE. Conclusions: Despite many innovations in surgical techniques, there is no surgical procedure that is superior to others to reduce DGE. Further larger prospective randomized studies are needed.

Bimagnetic metal constructed core-shell structure of Fe@Co nanowires for multi-band microwave absorption

引用

Progress in Natural Science:Materials International 2024年第2期34卷 354-361页

作者： ping-an Yang Rui Cai Haibo Ruan Nanqing zhang Xin Huang Rui Li Yuxin zhang Yi lu Zhihao Zhou School of Automation Chongqing University of Posts and Telecommunications Chongqing Key Laboratory of Materials Surface & Interface Science Chongqing University of Arts and Sciences College of Engineering and Technology Zunyi Normal College College of Material Science and Engineering Chongqing University

Controlled fabrication of materials by surface modification techniques has been a hot research topic. In this paper,one-dimensional(1D) core-shell structure Fe@Co nanowires(NWs) were successfully prepared by anchoring 0-dimensional(0D) Co nanoparticles on 1D Fe NWs based on the in situ reduction method. The electromagnetic parameters of the specimens at a filler mass fraction of 25 wt% were tested and the microwave loss mechanism was deeply analyzed. Binary magnetic metals in a core-shell structure have excellent multi-band microwave absorption capability(S-band, X-band and Ku-band). This is due to the heterogeneous interface and magnetic coupling effects tuning the dielectric and magnetic loss. This study offers a workable plan for creating effective multi-band magnetic metal-based microwave absorbers.
