Abstract: Electroencephalography (EEG)-based brain computer interfaces (BCIs) transform spontaneous/evoked neural activity into control commands for external communication. While convolutional neural ...

Abstract: Convolutionally precoded polar codes known as polarization-adjusted convolutional (PAC) codes are a promising variant of polar codes for short block lengths ...

WiMi Hologram Cloud Inc. (NASDAQ: WiMi) focuses on holographic cloud services, primarily concentrating on professional fields such as in-vehicle AR holographic HUD, 3D holographic pulse LiDAR, ...

Communication-system designers have always had to deal with trade-offs among data reliability, efficient use of available spectrum, data throughput, and cost. Error-correction coding (ECC) is one of ...

FEC (forward-error-correction) techniques correct errors at the receiver end of digital communications systems. In contrast with error-detection and retransmission ...

Neural decoding is the study of what information is available in the electrical activity (action potentials) of individual cells or networks of neurons. Studies of neural decoding aim to identify what ...

自21世纪初以来，类似2024年的极端事件频率明显上升，与印度洋加速增温趋势同步。其机制在于，持续升高的背景海温增强了大气对海温异常的响应，热带对流系统对海温扰动“敏感度”显著提升。增强的对流通过环流调整使更多水汽向中国南方汇聚，为极端降水提供有利条件。需要说明的是，该结论并不否定太平洋ENSO的重要作用，但在当前气候背景下印度洋局地影响更为突出，反映出区域极端降水驱动机制的结构性转变。
