Biological fundamentals and recent progress of artificial sensory neurons are systematically *** device, performance metrics, and potential applications of artificial sensory neurons are *** for the future development of artificial sensory neurons are discussed. Spike-based neural networks, which use spikes or action potentials to represent information, have gained a lot of attention because of their high energy efficiency and low power consumption. To fully leverage its advantages, converting the external analog signals to spikes is an essential prerequisite. Conventional approaches including analog-to-digital converters or ring oscillators, and sensors suffer from high power and area costs. Recent efforts are devoted to constructing artificial sensory neurons based on emerging devices inspired by the biological sensory system. They can simultaneously perform sensing and spike conversion, overcoming the deficiencies of traditional sensory systems. This review summarizes and benchmarks the recent progress of artificial sensory neurons. It starts with the presentation of various mechanisms of biological signal transduction, followed by the systematic introduction of the emerging devices employed for artificial sensory neurons. Furthermore, the implementations with different perceptual capabilities are briefly outlined and the key metrics and potential applications are also provided. Finally, we highlight the challenges and perspectives for the future development of artificial sensory neurons.

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

以Ni纳米材料为研究对象,提出了一种新的基于超声辅助的表面增强Raman散射(SERS)基底的制备方法,以实现对生物分子罗丹明6G(R6G)的高灵敏检测。首先,通过超声辅助法制备Ni纳米溶液,然后,采用旋涂法制备SERS基底,以R6G为探针分子,研究了基底的SERS活性、重复性以及在基底制备过程中加入表面活性剂甲基丙烯酸甲酯(MMA)对基底SERS活性的影响。结果表明,在加入MMA的实验条件下,基底表面的纳米颗粒分散更加均匀,能提供的SERS热点更多,有助于增强基底的SERS强度。该SERS基底对R6G的最低检测限(LOD)为1×10^(-6)mol/L,增强因子约为2.56×10^(4),重复性测试的相对标准偏差为10.19%(R6G浓度为1×10^(4)mol/L)。该方法经济、简单、快速、有效,可以作为未来生物传感应用的候选方法。

Meningeal lymphatic vessels form a relationship between the nervous system and periphery, which is relevant in both health and disease. Meningeal lymphatic vessels not only play a key role in the drainage of brain metabolites but also contribute to antigen delivery and immune cell activation. The advent of novel genomic technologies has enabled rapid progress in the characterization of myeloid and lymphoid cells and their interactions with meningeal lymphatic vessels within the central nervous system. In this review, we provide an overview of the multifaceted roles of meningeal lymphatic vessels within the context of the central nervous system immune network, highlighting recent discoveries on the immunological niche provided by meningeal lymphatic vessels. Furthermore, we delve into the mechanisms of crosstalk between meningeal lymphatic vessels and immune cells in the central nervous system under both homeostatic conditions and neurodegenerative diseases, discussing how these interactions shape the pathological outcomes. Regulation of meningeal lymphatic vessel function and structure can influence lymphatic drainage, cerebrospinal fluid-borne immune modulators, and immune cell populations in aging and neurodegenerative disorders, thereby playing a key role in shaping meningeal and brain parenchyma immunity.
