We propose that the core mass function(CMF) can be driven by filament fragmentation. To model a star-forming system of filaments and fibers, we develop a fractal and turbulent tree with a fractal dimension of 2 and a Larson's law exponent(β) of 0.5. The fragmentation driven by convergent flows along the splines of the fractal tree yields a Kroupa-IMF-like CMF that can be divided into three power-law segments with exponents α =-0.5,-1.5, and-2, respectively. The turnover masses of the derived CMF are approximately four times those of the Kroupa IMF,corresponding to a star formation efficiency of 0.25. Adopting β = 1/3, which leads to fractional Brownian motion along the filament, may explain a steeper CMF at the high-mass end, with α =-3.33 close to that of the Salpeter IMF. We suggest that the fibers of the tree are basic building blocks of star formation, with similar properties across different clouds, establishing a common density threshold for star formation and leading to a universal CMF.

目前国内外评论泉镜花甲午中日战争五部曲时存在两种倾向:一是认为其战争观中存在矛盾构造;二是认为其是战争“绝缘体”,反战思维较为明显。但值得注意的是,厌恶战争并不是泉镜花甲午中日战争文学的显著标签。五部曲的开篇《预备兵》和《海战余波》是与明治时期国家进程同频的战争小说,但作品将显露出明治国家侵略意识的国家主义内嵌于人物形象和故事情节,使泉镜花在起步阶段便背离了战争文学创作的历史使命。《海城发电》和《琵琶传》在五部曲中起到了承前启后的作用,前者延续了《预备兵》中的生硬手法,后者则开始出现厌战主题。这种矛盾现象的产生,与“观念小说”的文体出现了转变和身处时代洪流作家的思想转化有关。收关之作《凯旋祭》虽然在五部曲中被称为厌战色彩最明显的作品,但泉镜花关注到的仅仅是甲午中日战争带给日本民众的影响,并未关心日本发动的帝国主义侵略性质的甲午中日战争带给中国的伤害。

针对现有的基于深度学习的高光谱图像超分辨率重建方法无法通用于不同波段的高光谱图像以及缺乏可解释性等问题.提出一种融合光谱子空间映射和模型引导的高光谱图像超分辨率算法.首先,使用光谱子空间分解将原始图像映射到低维空间中,既可以增加光谱间的相关性又可以去除不同波段高光谱图像对网络的限制.其次,使用小波变换将稀疏矩阵分解为高频特征和低频特征,挖掘图像中的纹理和结构等高频信息.再者,以超分辨率重建模型为指导,将ADMM分解后的子模型优化展开为深度网络的形式,增加了深度网络设计的可解释性.最终,使用逆小波变换后将重建的系数矩阵映射到原始的全谱空间中.实验表明,提出的方法在定量指标和主观视觉方面均表现优异.

The distributed randomness beacon(DRB) is a crucial tool for continuously generating unpredictable, bias-resistant,and publicly verifiable random numbers on a regular basis. This is particularly useful for applications such as lotteries, electronic voting, and cryptographic parameter generation. However, existing studies either require complex communication or rely on a public bulletin board to meet security requirements. This brings a performance bottleneck when dealing with a large number of participants. This paper introduces a novel DRB protocol PltcRB based on timed commitments, eliminating the need for a public bulletin board. Our approach achieves optimal communication complexity of O(n) while maintaining the desired properties of a DRB protocol. The computation complexity is also O(n) when n is larger than the security parameter κ. These results demonstrate the practicality and performance of PltcRB, supported by our experimental analysis under various configurations.

数字化转型正成为制造企业构筑持续竞争优势的必要路径，这一过程中遇到的障碍及解决机制值得进一步研究。基于3家制造企业的案例研究，本文发现，制造企业数字化转型面临的障碍根源于能力悖论、合作悖论和治理悖论等悖论式困境。当高管能够接受冲突的存在并将矛盾的要素差异化对待时，高管基于“矛盾认知框架”指引企业实施分割适应式数字化转型。而当高管将悖论式困境转化为统一体并整合处理矛盾要素时，高管借助“辩证认知框架”引领企业实施整体共演式数字化转型。由此，本文构建了认知视角下制造企业数字化转型微观机制的理论框架，不仅贡献于数字化转型的文献，还为制造企业如何有效应对转型中遇到的障碍提供实践指导。
