With the swift advancement of neural networks and their expanding applications in many fields, optical neural networks have gradually become a feasible alternative to electrical neural networks due to their parallelism, high speed, low latency, and power consumption. Nonetheless, optical nonlinearity is hard to realize in free-space optics, which restricts the potential of the architecture.

鲁迅以自身经历为原型创作的小说《孤独者》,显示出现代知识分子面对传统礼俗时的复杂心态。鲁迅将魏连殳对于祖母葬礼的“照旧”与“不哭”统一于批判庸众的启蒙逻辑之下。而在批判庸众之外,魏连殳的选择中包含着更为幽微的情感指向。鲁迅以魏连殳之“大殓不哭”,体现出现代情感主体对于传统礼俗情感异化机制的反思,这一反思路径的形成,与鲁迅在父亲临终时的礼俗创伤体验有关。魏连殳之“照旧”,从情感角度而言,乃是出于对祖母葬礼情感纯粹性的维护。而现实中鲁迅之“照旧”,则更有对母亲礼俗情感需求的尊重。鲁迅现实选择与文学书写间的关联和差异,正体现出转型期知识分子启蒙理性和个人情感间的冲突与张力。

作者： Jingjing Liu Yifei Xu xingwang Lian Tianming Liu Haohao Ning xi jiang Shixin Yu Shikun Liu Lu Huang xiaojun Sun jiangyong Li Dongfu Xu School of Life Science and Technology， University of Electronic Science and Technology of China Department of Computer Science， the University of Georgia School of Automation Engineering， Northeast Electric Power University

The perception of salty taste is crucial for individuals to make healthy food choices. Yet， the brain electrophysiological signals underlying salty taste perception have been poorly described. In this study， electroencephalography (EEG) was used to record brain activity induced by NaCl solution as a salty taste stimulus. A combination of a custom delivery device and stimulation paradigm was employed to preserve the salty taste signal clearly. A stimulus-response capture method was proposed that could adapt to individual differences in brain responses to salty taste and accurately segment salty taste response signals. Applying this method to the EEG processing workflow can form a complete data processing framework. The results showed that the neural response induced by salty taste reached a high activity level in the initial stage within a short period (0.2s)， and there was a sustained periodic response within 0.75s after the stimulation. Moreover， the salty taste information in the EEG signal was decoded， and discrimination of two similar concentrations of salty taste solutions was achieved far above the chance level (average identification rate: 89.66%). This study demonstrated experimental paradigms and research methods for understanding salty taste perception， which could provide references for research on other basic tastes.

为揭示数字化背景下政府参与产业链协同创新的演化过程,本研究以“链长制”为蓝本,构建了产业链链主企业、链上企业与地方政府的三方演化博弈模型。通过分析各博弈主体的策略选择及不同选择下均衡点的稳定性,并对结果进行赋值仿真,探讨关键参数如何影响博弈主体的行为演化。研究发现,政府参与产业链协同创新系统经历了“起步-稳定合作-成熟”三个演化阶段,各阶段分别稳定在不同状态。为避免政府规制时出现企业不合作的情形,政府部门应根据各地市场状况不断调整政策,以达到稳定状态。随着政府激励力度和监管力度的加大,企业参与产业链协同创新的概率增大。此外,数字技术赋能系数的增加会提高企业参与协同创新的概率,而数据安全风险系数的增加则会降低企业参与协同创新的概率。
