The virtual private cloud service currently lacks a real-time end-to-end consistency validation mechanism, which prevents tenants from receiving immediate feedback on their requests. Existing solutions consume excessive communication and computational resources in such large-scale cloud environments, and suffer from poor timeliness. To address these issues, we propose a lightweight consistency validation mechanism that includes real-time incremental validation and periodic full-scale validation. The former leverages message layer aggregation to enable tenants to swiftly determine the success of their requests on hosts with minimal communication overhead. The latter utilizes lightweight validation checksums to compare the expected and actual states of hosts locally, while efficiently managing the checksums of various host entries using inverted indexing. This approach enables us to efficiently validate the complete local configurations within the limited memory of hosts. In summary, our proposed mechanism achieves closed-loop implementation for new requests and ensures their long-term effectiveness.

In recent years, Software-Defined Networks （SDNs） have become a promising technology to improve network utilization. However, limited flow table size and long deployment delays may result in low network performance in large-scale networks and a poor user experience. While a typical solution to this issue is routing aggregation （i.e., wildcard routing）, the aggregation feasibility problem and reduced network performance may be encountered. To address this dilemma, we first design a novel wildcard routing scheme, called the Tag-based Rule Placement Scheme （TRPS）. We then formulate a Hybrid Routing by Joint optimization of Per-flow routing and Tag- based routing （HR-JPT） problem, and prove its NP-hardness. An algorithm with a bounded approximation factor is designed for this problem, and the proposed methods are implemented on a Mininet platform. Extensive simulation results show that our methods are efficient for wildcard/hybrid routing. For example, our proposed tag-based wildcard rule placement scheme can reduce the number of required rules by about 65% on average compared with previous wildcard routing methods. Our proposed hybrid routing algorithm can increase network throughput by about 43% compared with existing hybrid routing solutions.

量子点(Quantum dots)由于具有优异的光电特性,广泛应用于发光与显示、太阳能电池、光催化等领域,它的发现和合成获得了2023年诺贝尔化学奖。采用量子点色转换的Micro-LED全彩化显示技术无需巨量转移,有望实现大规模量产,然而,量子点在高强度Micro-LED出光激发下的性能和寿命仍存在局限。基于此,本文研究了基于量子点@有序介孔(QDs@SBA-15)复合材料的Micro-LED色转换技术及其特性,有序介孔分子筛载体独特的孔道结构不仅能够有效提升Micro-LED色转换和光提取效率,且致密的有序介孔材料也一定程度上保障了量子点的稳定性。首先,通过时域有限差分方法(FDTD)建立了Micro-LED仿真模型,探究量子点粒径和有序介孔材料的孔径对光提取效率的影响;基于仿真结果指导,进一步采用物理共混法制备了QDs@SBA-15复合材料,通过透射光谱、荧光激发光谱、紫外-可见光吸收谱等手段对其进行表征并确定浓度配比;最后,将该复合材料与聚二甲基硅氧烷(PDMS)混合固化成膜,并研究了其光致发光性能。实验结果发现,量子点粒径和介孔材料孔径的匹配度以及量子点和有序介孔材料的比例浓度是影响QDs@SBA-15复合材料发光效率及Micro-LED色转换性能的关键因素;通过优化,所得复合材料可获得优异的发光性能以及良好的环境稳定性,相比于纯量子点色转换层,复合材料的光提取效率提升了81.73%,复合材料的环境稳定性提升了14.33%,以Micro-LED作为蓝光光源组成的三基色发光器件工作色域达到了104.52%NTSC。本研究为量子点色转换Micro-LED显示技术提供了理论指导,为实现Micro-LED全彩化开辟了新路径。

一直以来,疼痛都是备受全世界关注的公共卫生问题,亟待解决。针刺是良好的镇痛疗法,具有整体调节的优势,针刺并非只改善疼痛患者某一方面的功能障碍,而对疼痛感觉、情绪、认知及社交等维度具有综合性影响。大脑是针刺镇痛过程中的最高级中枢,其中与学习、记忆以及情绪调节有关的海马参与疼痛多维度的形成与调节。随着针刺镇痛的脑机制研究逐步深入,针刺通过多角度调控海马以镇痛的机制值得关注,并有望成为解开针刺镇痛脑机制奥秘的落脚点,因此本研究围绕海马在疼痛中的作用及其介导针刺镇痛的研究展开探讨。

A possible approach to assess the fine grain OSL dating is discussed through comparison of equivalent dose (DE) values and ages obtained by IRSL and GLSL of fine grains for 31 sediment samples from North China. The IRSL and GLSL were measured with the same aliquots for each sample, i.e. shine-down was by 100 s of IRSL (880 nm) followed by 100 s of GLSL (514 nm) on the same discs. The DE values and ages found by IRSL are in good agreement with those by GLSL within 1-2σ for 80% samples, especially for aeolian loess samples. Considering that IRSL from feldspar differs obviously from GLSL dominated from quartz in dose response, thermal stability and optical bleaching characteristic, the agreement between the DE values may be taken as evidence that the two clocks of IRSL and GLSL had been well reset during deposition. The consistent ages of IRSL and GLSL, in turn, may be referred to an indicator to evaluate the fine grain OSL dating of sediments.

The field investigations of geomorphology and Quaternary sediment sequences show that the sediment stratigraphic profile containing the skull of the Homo sapiens Daliensis (Dali Man) at Tianshuigou trench, Jiefang Village (109°44’E, 34°52’N ), Dali County, Shaanxi Province, is composed of the loess-paleosol sequence, 17.3 m thick, in the upper part, and the alluvial silts, fine sands and sandy gravels interbedded, 15.4 m thick, in the lower part. There are the well developed layers L1, S1, L2 and S2 in the loess-paleosol sequence of the profile, which are comparable to those of the Luochuan loess section on the basis of magnetic succeptibility measurements and IRSL dating of the loess samples. An alluvial gravel layer, where the skull of the Dali Man was discovered, is in 13 m beneath the bottom of paleosol S2, implying that, the age of the Dali Man must be older than about 247 kaBP when the paleosol S2 began to be developed.

Six granite samples were collected from six difference elevation locations at the Hua Shan in a main ridge of the Qinling Mountain. Apatite and zircon separated from these six samples were dated by the fission track technique. An assessment of the Cenozoic uplift or exhumation rate was obtained from the altitude difference of sampling samples dated by fission track, and from the difference of fission track dates of both apatite and zircon for a sample. The preliminary results suggest that the beginning of uplift of the Hua Shan was as early as 68.2 MaBP and the uplift rates for different periods are 0.02-0.19 mm/a (from the elevation difference) or 0.12-0.16 mm/a (from two mineral fission track dates). The average uplift rate is 0.12 mm/a (from the elevation difference) or 0.14 mm/a (from two mineral fission track dates). The uplift of the Hua Shan might accelerate since (17.8±2.0) MaBP, and the average uplift rate is about 0.19 mm/a.
