光纤传感技术揭示农业对土壤结构的深远影响土壤常被视为简单的土质材料,但其本质是一个活跃的生态系统,具备类似天然海绵的功能。然而,中国科学院地质与地球物理研究所石启斌博士联合国际科研团队的研究发现,现代农业实践中如深翻和使用重型农机,可能对这一复杂结构造成显著破坏。该成果发表于《科学》杂志,揭示了健康土壤内部存在的微观孔隙网络——类似于毛细血管系统,有助于水分渗透至地层深处,并被植物根系有效吸收。频
构建高精度温湿度传感体系以支撑ADAS传感器模块稳定运行ADAS系统中的摄像头、毫米波雷达和激光雷达等核心感知组件,其性能高度依赖于环境条件的稳定性。温度与湿度的波动不仅会引发传感误差,还可能缩短设备使用寿命,甚至带来安全隐患。在高阶自动驾驶的发展背景下,构建一套精准、稳定的温湿度感知机制,已成为提升ADAS系统可靠性的关键技术路径。ADAS传感器模块所处的运行环境极具挑战性,车辆在行驶过程中需应

AbstractSpike sorting is an algorithmic process to extract the activity of individual neurons from extracellular electrophysiology recordings. With the ballooning use of high density probes, such as N
AbstractPrecise and up-to-date information about animal location and identity allows us to better quantify individual behaviors in studies of neural activity, cognition, and animal health. In socially
AbstractEffective decision making in dynamic environments requires flexible evidence accumulation. Although models often express this flexibility as an adaptive “leak” parameter governing accumulator
AbstractMating in insects typically triggers a post-mating response (PMR) in females, characterized by reduced receptivity to re-mating and increased oviposition, which ensures numerous and viable off
AbstractThe cost of expressing unnecessary genes on growth has been explained at the population level through balanced growth assumptions. However, due to the high degree of stochasticity in growth an
AbstractThe human brain seamlessly integrates internally generated thoughts with incoming sensory information, yet the large-scale networks that support these functions -- the (Default Network, DN) an
AbstractAccurate projections of temperate tree growing seasons under climate change require representing developmental constraints that determine tree resource allocation. Recent work has identified t
AbstractNatural Killer (NK) cells contribute to early immunity against Plasmodium falciparum by recognizing and eliminating infected red blood cells (iRBCs), a process mediated in part by the integrin
AbstractPerception requires integrating sensory input over time to construct coherent experiences. Alpha oscillations have been proposed to define the temporal resolution of perception, yet empirical
