Layer-3 load balancing is a key topic in the networking field. It is well acknowledged that flowlet is the most promising solution because of its good trade-off between load balance and packet reordering. However, we find its one significant limitation: it makes the forwarding paths of flows unpredictable. To address this limitation, this paper presents BurstBalancer, a simple yet efficient load balancing system with a sketch, named BalanceSketch. Our design philosophy is doing less changes to keep the forwarding path of most flows fixed, which guides the design of BalanceSketch and balance operations. We have fully implemented BurstBalancer in a small-scale testbed built with Tofino switches, and conducted large-scale NS-2 simulations. Our results show that BurstBalancer achieves 5%similar to 35% smaller FCT than LetFlow in symmetric topology and up to 30 x smaller FCT in asymmetric topology, while 58 x fewer flows suffer from path changing. All related codes are open-sourced at Github(2).

苯并噻二唑(benzothiadiazole,BTH)可诱导葡萄抗病性,影响葡萄次生代谢。为探究外源BTH对霞多丽葡萄和葡萄酒香气化合物的影响,试验于霞多丽葡萄转色期(花后65 d)整株喷施50 mg/L BTH水溶液,以仅喷施水溶液为对照,测定成熟葡萄和所酿葡萄酒的理化指标、酚类以及游离态和结合态香气构成。结果表明,BTH处理提高了葡萄的还原糖含量、pH、可溶性固形物含量、皮果比,葡萄酒中的甘油含量、pH、干浸出物含量和酒精度,降低了葡萄酒的总酸、挥发酸和残糖含量。BTH处理的葡萄和葡萄酒较CK具有更高浓度的总酚、总黄酮、总黄烷醇和总黄酮醇。同时,BTH处理提高了葡萄和葡萄酒中直链脂肪族、芳香族、支链脂肪族、萜烯、降异戊二烯类香气的种类和含量,降低了C_(6)/C_(9)化合物含量。BTH通过提高乙酸异戊酯和β-大马士酮浓度,显著增强葡萄酒花果香,减弱植物味。研究结果可为BTH调控霞多丽葡萄和葡萄酒香气的葡萄园管理实践提供科学数据支撑。

针对传统的k-means算法应用在图像分割时需要手动调试参数的缺点,提出了一种将密度峰算法、最近邻插值算法和k-means聚类算法相结合的图像分割算法。用最近邻插值算法缩小原图像像素点,用密度峰算法提取图像的中心点,并将该中心点作为k-means的初始聚类中心,用k-means算法对原始图像进行图像分割。实验结果表明,改进算法拥有更强的自适应性和鲁棒性。

Titanium (Ti) and its alloys are widely used in dental implants due to their favorable mechanical properties and biocompatibility. Surface characteristics, including physical and chemical properties, are crucial factors to enhance the osteogenesis performance of Ti. The aim of this study is to evaluate amino group surface modification to facilitate the osteogenic potential and bone repair of dental implants bothin vitroandin vivo. Herein, amino group-modified Ti surfaces were constructed via the plasma-enhanced chemical vapor deposition (PECVD) technique with an allylamine monomer. The adhesion, proliferation, alkaline phosphate activity and osteogenesis-related genetic expression of MG-63 cells on the surfaces were performedin vitroand presented a significant increase in amino group-modified Ti compared with that in Ti. Thein vivostudy in miniature pigs was evaluated through micro-computed tomography analysis and histological evaluation, which exhibited enhanced new bone formation in amino group-modified Ti compared with that in Ti after implantation for 4, 8 and 12 weeks. Consequently, amino group surface modification with the PECVD technique may provide a promising modification method to enhance the osteogenesis performance of Ti implants.

ESG既是CSR的进化产物,又是推进CSR的重要力量。当前,ESG已发展为一项全球性的热门话题,引发了学术界的广泛关注。然而,由于ESG固有的复杂性,围绕其展开的研究得出了差异化甚至相互冲突的结论,一些学者对ESG本身的理解也存在较大差异。为此,本文运用系统文献综述法,按照主题编码结果对ESG相关文献进行全面回顾,构建出“ESG投资—ESG信息披露与评价—ESG治理”的整合性研究框架。在此基础上,本文进一步探究了上述三种ESG实践的逻辑起点,并提出:(1)ESG投资的逻辑起点是实现不同价值类型之间相互转化;(2)ESG信息披露与评价的逻辑起点是对组织边界的拓展及模糊化,实现外部性内部化过程;(3)ESG治理的逻辑起点是组织治理逻辑的转变,即由单一治理逻辑转向混合治理逻辑。本文为重新认识ESG提供了新的思路,帮助未来研究者厘清现有ESG研究脉络并指明未来研究方向,同时为参与ESG实践的行动主体提供了新的范式选择思路。

Background: Aging confers an increased risk of developing cancer, and the global burden of cancer is cumulating as human longevity increases. Providing adequate care for old patients with rectal cancer is challenging and ***: A total of 428 and 44,788 patients diagnosed with non-metastatic rectal cancer from a referral tertiary care center (SYSU cohort) and the Surveillance Epidemiology and End Results database (SEER cohort) were included. Patients were categorized into old (over 65 years) and young (aged 50-65 years) groups. An age-specific clinical atlas of rectal cancer was generated, including the demographic and clinicopathological features, molecular profiles, treatment stra-tegies, and clinical ***: Old and young patients were similar in clinicopathological risk factors and molecular features, including TNM stage, tumor location, tumor differentiation, tumor morphology, lym-phovascular invasion, and perineural invasion. However, old patients had significantly worse nutritional status and more comorbidities than young patients. In addition, old age was inde-pendently associated with less systemic cancer treatment (adjusted odds ratio 0.294 [95% CI 0.184-0.463, P < 0.001]). We found that old patients had significantly worse overall survival (OS) outcomes in both SYSU (P < 0.001) and SEER (P < 0.001) cohorts. Moreover, the death and recurrence risk of old patients in the subgroup not receiving chemo/radiotherapy (P < 0.001 for OS, and P = 0.046 for time to recurrence [TTR]) reverted into no significant risk in the subgroup receiving chemo/***: Although old patients had similar tumor features to young patients, they had unfa-vorable survival outcomes associated with insufficient cancer care from old age. Specific trials with comprehensive geriatric assessment for old patients are needed to identify the optimal treatment regimens and improve unmet cancer *** registration: The study was registered on the research

The symmetry breaking and its interplay among spin, charge, and lattice degrees of freedom is crucial for understanding correlated quantum states such as charge density waves (CDWs) and unconventional superconductivity. Here, we report the discovery by low-temperature scanning tunneling microscopy/spectroscopy of unconventional charge-spin-intertwined density waves in magnetic kagome metal GdTi3Bi4, which exhibits the one-third magnetization plateau. We reveal the emergence of 3Q CDWs incommensurate with the crystalline lattice in both periodicity and orientation, breaking all mirror and rotation symmetries. The CDW exhibits incommensurate-commensurate transitions in an applied magnetic field and transitions between 3Q and 1Q CDWs as a function of field and temperature, accompanied by changes in the spatial symmetries. Remarkably, the quantum and classic melting of the CDWs exhibits a phase structure which is consistent with the magnetization phase diagram of bulk GdTi3Bi4, providing strong evidence for the intertwined charge-spin density wave order. The origin of the charge-spin intertwinement is further evidenced by the observed hybridization between itinerant electrons and Gd local moments. Our findings uncover an unconventional form of charge-spin orders and offer new insights into a broad class of multi-components density wave formation in kagome and other correlated quantum materials. © 2025, CC0.

9th International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII 2019

Robots such as drones have been leveraged to perform structure health inspection such as bridge inspection. Big data of inspection videos can be collected by cameras mounted on drones. In this project, we develop image analysis algorithms to support bridge engineers to analyze the big video data. Bridge engineers define the region of interest initially, then the algorithm retrieves all related regions in the video, which facilitates the engineers to inspect the bridge rather than exhaustively check every frame of the video. To perform this task, we propose a Multi-scale Siamese Neural Network. The network is initially trained by one-shot learning and is fine-Tuned iteratively with human in the loop. Our neural network is evaluated on three bridge inspection videos with promising performances. Copyright © SHMII 2019. All rights reserved.
