Abstract Literary scholars have long observed the 昀氀uctuating popularity of romantic love in Chinese 昀椀ction, and the existence of periods when romantic love was particularly central to Chinese 昀椀ction: The High Tang Dynasty (short stories), the Yuan Dynasty (plays), the High Qing Dynasty (scholar-beauty novels), and the most recent period (modern series, web novels).但是,这些观察结果仍然是质的,中国的整体文化历史仍然未知。中国爱的历史上是否有模式?我们可以定量描述它吗?我们可以解释吗?在这里,我们提供了一个新的数据库,从唐朝(618 AD)到现代时代(2022年)的中国昀碗ction(n = 3496)的摘要图(n = 3496)。使用语言探究方法,我们首先认为,从长远来看,浪漫爱情的进化模式对应于文学学者和文化史学家报道的定性观察,在古代和现代阶段(1978年后)中有所增加。然后,我们测试这些模式是否可以通过人们对增加经济发展的偏好的变化来解释。与以前的工作一致,我们表明浪漫爱情的兴起与中国历史上经济发展的起伏相关。

甘蔗是世界上最重要的糖和能源作物。在甘蔗育种期间,技术是需求,方法是手段。我们知道,种子是甘蔗产业发展的基石。Over the past century, with the advancement of technology and the expansion of methods, sugarcane breeding has continued to improve, and sugarcane production has realized a leaping growth, providing a large amount of essential sugar and clean energy for the long-term mankind development, especially in the face of the future threats of world population explosion, reduction of available arable land, and various biotic and abiotic stresses.Moreover, due to narrow genetic foundation, serious varietal degradation, lack of breakthrough varieties, as well as long breeding cycle and low probability of gene polymerization, it is particularly important to realize the leapfrog development of sugarcane breeding by seizing the opportunity for the emerging Breeding 4.0, and making full use of modern biotechnology including but not limited to whole genome selection, transgene, gene editing, and synthetic生物学,结合遥感和深度学习等信息技术。鉴于此,我们从技术和方法的角度专注于甘蔗育种,回顾了主要历史,指出了当前的状态和挑战,并为智能育种前景提供了合理的前景。
合成生物学的进步促进了将异源代谢途径掺入各种细菌底盘中,从而导致靶向生物产品的合成。然而,异源生产途径的总产量可能会遭受低浮标,酶滥交,有毒中间体的形成或对竞争反应的中间损失,这最终阻碍了其全部潜力。基于蛋白质的细菌微校区(BMC)的自组装,易于修饰的,提供了一种复杂的方法来克服这些障碍,通过充当与细胞的调节性和代谢网络解耦的自主催化模块。More than a decade of fun- damental research on various types of BMCs, particularly structural studies of shells and their self-assembly, the recruitment of enzymes to BMC shell scaffolds, and the involve- ment of ancillary proteins such as transporters, regulators, and activating enzymes in the integration of BMCs into the cell's metabolism, has signi fi cantly moved the fi eld 向前。这些进步使生物工程师能够设计合成的多酶BMC,以促进乙醇或氢的产生,增加细胞多磷酸盐水平,并将甘油转化为丙二醇或甲酸盐或丙酮酸。这些开创性的努力揭示了合成BMC的巨大潜力,以封装非本性多酶生化途径以合成高价值产品。
The rational use of biologically active substances or plant growth stimulants from natural materials like seaweed is one of the most promising trends in agriculture, as seaweed is considered a safe and sustainable bio stimulant for improving plant growth, particularly under abiotic stress due to its high content of Cytokinin's, auxins, gibberellins, amino acids, phytohormones, Osmo protectants, mineral nutrients, and抗菌化合物。当前的工作探讨了海藻提取物对不同作物的影响,它们在植物中起的功能作用以及海藻提取物在综合作物管理系统中的潜在价值对可持续作物生产。各种元素会影响农业中使用的海藻提取物的有效性,例如海藻,制造方法和浓度,而应用技术被认为是海藻提取物在改善植物生长中有效性的决定因素。海藻提取物以两种基本方式合成:通过物理技术和化学方法。使用碱提取是最商业的方法,在维持生物活性成分方面非常有效。许多报告已经证实了海藻提取物在改善植物生长方面的疗效及其在改善种子发芽,改善根系的生长,提高幼苗生存率,提高幼苗生长和在非生物胁迫下提高植物的生长和生产力,并增强植物对病原体的耐药性。
To ensure reliable environmental perception in the realm of autonomous driving, precise and robust multi- object tracking proves imperative.This study proposes an innovative approach to multi-object tracking by combining YOLOv9's sophisticated detection capabilities with an enhanced DeepSORT tracking algorithm, enriched through the integration of optical flow.In the proposed method, the YOLOv9 detector acutely identifies objects in input images, and these detected entities are subsequently transmitted to the optimized DeepSORT tracking algorithm.The principal contribution of this study lies in improving the Kalman filter measurement model within DeepSORT by incorporating robust local optical flow, thus adding a velocity dimension to the filter's update vector.这种新颖的方法可显着提高遮挡,快速运动和外观变化的追踪弹性。Evaluations on MOT17 and KITTI show substantial improvement gains of 2.42%, 2.85%, and 1.84% for HOTA, MOTA, and IDF1, respectively, on MOT17, and 1.94% in MOTA and 2.09% in HOTA on KITTI.The proposed method particularly excels in managing scenarios involving dense traffic and light variations, which are recurrent problems in dynamic urban environments.This enhanced performance positions the proposed solution as an essential component of future perception architectures for autonomous vehicles, promising safer and more efficient navigation in the complex real world.
Satellites, now numbering over 10,000 as of 2024 [43], have transitioned from extraordinary space achievements to common orbital fixtures, especially with the surge in small satellites like CubeSats and nanosatellites. This accessibil- ity has allowed diverse entities, including universities and startups, to engage in space projects. However, the ease of developing these smaller satellites often comes at the cost of security, making them prone to cyberattacks. Teams be- hind these projects may lack comprehensive cybersecurity knowledge, leading to significant vulnerabilities. Furthermore, the evolving nature of cybersecurity means satellite software can quickly become outdated, with updates in orbit posing a challenge, as noted in research like Willbold et al. [47]. Concurrently, there has been a significant evolution in satellite on-board computing, particularly in processing power. This advancement enables small satellites to run full operating systems like Linux, a shift from the basic systems in earlier models. This technological progress enhances satellite func- tionalities but also adds complexity and vulnerability, neces- sitating stronger security measures. As systems become more sophisticated, they are more susceptible to threats, requiring a layered defense approach. Sandboxing is one of the effective methods to isolate software vulnerabilities and protect these advanced systems. In this paper, we discuss the process of selecting a sandbox- ing mechanism for a satellite project currently under develop- ment, named RACCOON [41]. The project's goal is to design
