The rapid development of emerging technologies observed in recent years,such as artificial intelligence, machine learning, mobile internet, big data,cloud computing, and the Internet of Everything, are generating escalatingdemands for expanding the capacity density, and speed in next-generation opticalcommunications. This poses a significant challenge to existing communicationtechniques. Within this context, the integration of near-infraredbroadband, tunable, and high-gain luminescent materials into silicon opticalcircuits or fiber architectures to transmit and modulate light shows enormouspotential for advancing next-generation communication techniques. Here, thisreview provides an overview of the recent breakthroughs in near-infrared luminescentepitaxial/colloidal quantum dots, and metal-active-center-doped materialsfor broadband optical amplifiers and tunable lasers. We also expound onefforts to enhance the bandwidth and gain of these materials-based amplifiersand lasers, exploring the challenges associate with developing ultra-broadbandand high-speed optical communication systems. Additionally, the potentialapplications in Fifth Generation Fixed Networks, integration with 5G and 6Gwireless networks, compensation for current Si electronic based CMOS forhigh computing capability, and the prospects of these light sources for nextgenerationoptoelectronic devices are discussed.

Fruit wart is an important appearance trait influencing consumer preferences of bitter gourd(Momordica charantia L.).The molecular genetic mechanisms underlying fruit wart formation in bitter gourd are largely *** this study,genetic analysis based on four generations showed that fruit wart formation in bitter gourd was controlled by a single dominant locus named as *** Fwa locus was initially mapped into a 4.82 Mb region on pseudochromosome 4 by BSA-seq analysis and subsequently narrowed down to a 286.30 kb region by linkage analysis.A large F2population consisting of 2360 individuals was used to screen recombinants,and the Fwa locus was finally fine mapped into a 22.70 kb region harboring four protein-coding genes through recombination ***04g1399,encoding an epidermal patterning factor 2-like protein,was proposed as the best candidate gene for Fwa via sequence variation and expression *** addition,a 1-bp insertion and deletion(InDel)variation within MC04g1399 was converted to a cleaved amplified polymorphic sequence(CAPS)marker that could precisely distinguish between the warty and non-warty types with an accuracy rate of 100%among a wide panel of 126 bitter gourd germplasm *** results not only provide a scientific basis for deciphering the molecular mechanisms underlying fruit wart formation but also provide a powerful tool for efficient genetic improvement of fruit wart via marker-assisted selection.

Super-resolution （SR） is a widely used tech- nology that increases image resolution using algorithmic methods. However, preserving the local edge structure and visual quality in infrared （IR） SR images is challenging because of their disadvantages, such as lack of detail, poor contrast, and blurry edges. Traditional and advanced methods maintain the quantitative measures, but they mostly fail to preserve edge and visual quality. This paper proposes an algorithm based on high frequency layer features. This algorithm focuses on the IR image edge texture in the reconstruction process. Experimental results show that the mean gradient of the IR image reconstructed by the proposed algorithm increased by 1.5, 1.4, and 1.2 times than that of the traditional algorithm based on L1- norm, L2-norm, and traditional mixed norm, respectively. The peak signal-to-noise ratio, structural similarity index, and visual effect of the reconstructed image also improved.

围绕“安全保障、技术为基、标准先行”这一网络安全治理方案,我国个人信息安全标准体系正在形成。透过对个人信息安全标准治理有关现象的观察,不论在市场标准向政府标准的转化中,抑或在标准自身的实施过程中,都呈现出许多异化现象。尽管个人信息安全标准化可以在技术治理主义的论证中获得正当性,但是有关标准化的进程不应忽视对标准自身局限性的认知、对被规制者的影响、与之相配套的认证制度建设,以及标准背后的权力真相。监管部门应当处理好个人信息安全“标准先行”与全领域、全要素治理法治化的关系。在为行政权力介入标准治理划定必要界限的同时,监管部门应当摒弃工具主义的管制思维,在个人信息安全标准化进路中更多地关注公共服务。

互联网信息内容监管工具不论名称种类、使用方式都与传统监管工具存在不同,体现出效果导向、功能主义的监管思路。从规范主义的视角观之,互联网信息内容监管工具在合法性、合理性以及权责分配方面仍存争议。基于行政管理法治化的目标,需要适度打通功能主义与规范主义的关联。一方面,明确动态适应性监管和生态化治理的功能定位,推动形成适应商业形态变化和契合技术特征的风险治理结构;另一方面,在立法上提升行政行为型式的容许性,在执法上探索符合比例原则的治理方案,并发展程序性的裁量限制机制。

采用XRD、SEM+EDS和电化学装置对复合合金Ti_(1.8)(VFe)CrNi_(0.2)+XLaNi_5(X=0,5,10,20,质量分数,%,下同)的组织形貌、相结构及其在323 K下电化学性能进行表征。结果表明,随LaNi_5的添加,合金由胞状晶逐渐转变为树枝晶;相结构由bcc结构的Ti-V-Cr基相和体心四方结构的Cr-Ni-Ti-Fe主相转变为Ti-V-Cr-Fe-Ni为主相的bcc结构和La-Ni第二相。电化学性能显示,随X的变化,复合合金的活化及放电容量等呈规律性变化。X=5时,合金的活化和放电容量明显改善,仅需9次活化就达到最大值360 mAh/g,这是因为棒状晶的形成和第二相Cr-Ni-Ti-Fe相与Ti-V-Cr基相独特的协同作用所致。

针对传统的动静态PHP漏洞挖掘技术效率低、误报率高、漏洞匹配规则过于单一且不具有泛化性的问题,以及现有的以token序列、软件度量等作为特征的神经网络模型不能很好地理解代码语义的问题,提出了一种基于ASTNN深度神经网络的PHP漏洞挖掘方法。首先,根据表达式子树的概念及PHP抽象语法树的特点定义了表达式子树划分规则;其次,根据PHP抽象语法树的特殊结构对传统ASTNN深度神经网络的编码层进行了改进,在提高模型效率的同时更好地保留了抽象语法树所包含的语义信息。最终实验结果表明,基于改进后ASTNN网络的PHP漏洞挖掘方法相对于传统的漏洞挖掘方法具有更高的准确率及召回率。改进后的ASTNN深度神经网络模型适用于PHP语言漏洞挖掘领域。

产品责任能够发挥责任威慑与制度激励的双重作用,可作为自动驾驶交通事故责任救济的归责基础,但产品责任机制不论在其结构还是功能方面都存在许多无法圆满回应自动驾驶风险挑战的问题。政府可以通过“辅助侵权法机制实施”和“补强侵权法功能实现”两种方式参与自动驾驶交通事故责任救济,并可围绕两种方式分别设置实施机制。出于对政府介入的本能警惕,在没有显著失灵的情况下,通过产品责任发挥自身的激励性作用仍是第一序位的。即使需要发挥政府作用,为限制溢出效应设置规则也是必要的。
