针对AOMedia Video 1(AV1)编码时间较长的问题,基于不同纹理的视频内容与分区模式之间的联系,引入了虚拟子块的跨块梯度差来衡量图像纹理分布的差异,提出了一种快速块划分决策算法,以跳过非必要的分区模式。利用分区终止块大小与性能损失之间的联系,根据当前块大小自适应调整快速块划分的判断阈值,使得较小的编码块具有较宽松的跳过条件。与libaom相比,该算法在全帧内(All-Intra,AI)配置下平均可节省16.15%的编码时间,同时性能损失较小,有望被用于减少高分辨率视频的编码时间。

The current Internet has evolved during the last decade to a global provider of diverse applications. However, the underlying structure of routing and addressing has not evolved in the same pace and is somewhat inflexible. How to provide diverse routing services, support emerging communication paradigms based on limited and definite network resources has become an urgent challenge. This paper investigates the adaptive matching between routing and application through network function decomposition and composition, and proposes a polymorphic routing model to support diverse applications and emerging communication paradigms. The model splits complex routing functions into its constituents, and derives customized routing mechanisms supporting various applications by composing the routing constituents. The derivation process is modeled as a Markov Decision Process (MDP), and a polymorphic derivation algorithm is also proposed to derive customized routing instances for diverse applications. The model enables the network to self-adjust routing services dynamically to adapt to the different requirements of applications, supports coexistence of multiple routing modes and communication paradigms, and provides a feasible solution for the network compatibility and evolvement. We describe the key design and demonstrate the feasibility of polymorphic derivation by simulations. We also present case studies that demonstrate key functionalities the polymorphic routing model enables.

开放媒体联盟开发的第一代视频编码标准(Alliance for Open Media Video 1,AV1)作为新一代的开放式视频编码技术,以其高压缩效率和高质量视频输出等优势成为在线视频领域的主流编解码标准之一。旨在优化帧内预测编码技术以降低编码运行的计算复杂度,从而节约视频编码时间。为此,提出了长边采样(Long-side Sampling, LS)和长边稀疏采样(Long-side Sparse Sampling, LSS)的参考像素选择方法,根据块的划分方式规律地提取关键参考像素,以改进直流(Direct Current, DC)预测和亮度预测色度(Chroma from Luma, CfL)预测技术的性能。实验结果表明,LSS可以规避运算中的除法操作且减少大量加法计算量,在全I帧(All Intra, AI)和随机接入(Random Access, RA)配置下,相较原始算法平均编码时间减少11%和13%,同时节省0.03%和0.04%的Bj?ntegaard Delta Bit Rate(BDBR)。

Purpose: To explore the effect of comprehensive intervention based on transition theory in enhancing the readiness for discharge of post-operative breast cancer patients. Method: In a non-simultaneous controlled study test, 99 post-operative breast cancer patients hospitalized between August 2019 and February 2020 were selected as the control group and 93 post-operative breast cancer patients hospitalized between March and August 2020 were selected as the test group at a Grade A tertiary tumor hospital. While the control group used the conventional care model, the test group added a comprehensive intervention based on transition theory to the routine nursing, which focused on stimulating patients’ awareness of health transitions, assisting patients to identify health critical events, strengthening social support and promoting self-management. The differences between the two groups were compared in terms of patient readiness for discharge and patient evaluation of the quality of discharge teaching. Result: The total score of readiness for discharge was higher in the test group than in the control group (171.7 ± 24.5 vs. 155.9 ± 28.9) and the scores for “Self-condition” (55.6 ± 8.2 vs. 50.8 ± 9.7), “Disease Knowledge” (64.7 ± 13.1 vs. 57.7 ± 13.8), “Coping Ability after Discharge” (24.6 ± 4.8 vs. 22.2 ± 5.6), “Expected Social Support after Discharge” (26.8 ± 4.5 vs. 25.2 ± 4.8) were higher than those of the control group, and all differences were statistically significant (p < 0.05). The total score of the test group on the quality of discharge teaching scale was higher than that of the control group (162.1 ± 19.9 vs. 152.6 ± 28.7), and the scores for “Content that Patients Self-perceived they required before discharge” (53.2 ± 9.5 vs. 49.4 ± 12.1), “Content that Patients Actually Acquired before Discharge” (51.2 ± 9.2 vs. 48.3 ± 11.3) and “Guiding Skills and Effects of Discharge for Nurses” (110.9 ± 12.6 vs. 104.3 ± 19.00) were also higher than those of the control g

Purpose: To explore the preventive effect of Regional cooling comprehensive nursing on hand foot syndrome caused by pegylated liposomal doxorubicin (PLD). Method: Adopt overall sampling method. Patients who used the same adjuvant drugs from January to December 2020 were randomly divided into an intervention group and a control group. The patients in the two groups received routine nursing guidance and drug prevention for the use of amygdalin. The patients in the intervention group were required to take protective measures of Regional cooling during chemotherapy. The occurrence of hand foot syndrome during adriamycin liposome administration was compared between the two groups. Results: By comparing the adverse reactions of cases during Adriamycin Administration, the incidence rates of grade I, II and III hand foot syndrome in the control group were 28.8%, 7.6% and 27.5% respectively, and the incidence rates of grade I, II and III hand foot syndrome in the intervention group were 42.1%, 12.3% and 7.0% respectively, with statistical significance (P Conclusion: Regional cooling nursing and preventive behavior guidance can effectively reduce the severity of hand foot syndrome caused by adriamycin.

Background: Breast cancer has become an important disease burden harmful to women’s health. The treatment of breast cancer is mainly surgical treatment. In the context of enhanced recovery after surgery, the average length of hospital stay has been reduced, so there is increasing concern about postoperative patient discharge readiness. Objective: To identify factors influencing readiness for hospital discharge among patients having undergone breast cancer surgery and to explore the relationship between discharge readiness and the quality of discharge teaching. Methods: A total of 99 patients after breast cancer surgery at a regional tertiary medical tumor center in Guangzhou between June 2021 and December 2021 were collected using the convenience sampling method. A general data questionnaire, readiness for hospital discharge scale, and quality of discharge teaching scale were used to conduct a questionnaire survey on the subjects. Results: 83.8% of the patients feel ready for discharge, and the score of discharge readiness was 155.98 ± 28.87. The patients’ content received and the skills in teaching delivery were the influencing factors of discharge readiness. Discharged with a drainage tube was an independent factor of discharge readiness. Conclusions: Readiness for hospital discharge among patients undergoing breast cancer surgery was above medium level, and perfect intervention measures should be formulated for the influencing factors of discharge readiness. Especially, specific executable safeguard measures should be formulated for patients who are discharged early after surgery to promote the safety of home care.
