在工业自动化、航空航天、能源化工、智能制造等B端应用场景中，压力传感器作为核心的感知元件，其性能直接关系到系统的稳定性、安全性和控制精度。面对市场上主流的石英、扩散硅和陶瓷三类压力传感器，工程师常陷入“技术迷雾”：究竟哪种更适合我的 ...

This project implements an OFDM (Orthogonal Frequency-Division Multiplexing) communication system in Python. The system represents a simplified version of the WiFi (IEEE 802.11) PHY layer. It involves ...

Abstract: Automatic modulation classification (AMC) is crucial for ensuring secure and efficient operation of the Internet of Things (IoT). In this study, we focus on addressing the challenge of cross ...

The evidence is solid but not definitive, as the conclusions rely on the absence of changes in spatial breadth and would benefit from clearer statistical justification and a more cautious ...

Abstract: High-Frequency Link inverters (HFLIs) have attracted significant research attention owing to their compact design, high power density, and high efficiency. HFLI systems achieve power ...

Their specificity for the host is partly achieved by specific host adhesion mechanisms. As adhesins are required for the first step of colonization, they also constitute key virulence factors and have ...

PWM是Pulse Width Modulation的缩写，译为脉宽调制。 PWM是以方波为基波，用电平宽度表示信息的。PWM不改变基波频率，只是调制电平保持时间。因为方波只包含高、低两段电平，所以PWM常常做二进制调制。一般地，基波的高电平段被叫做“占”、On，而低电平段被叫做 ...

How does the new HackRF Pro perform in practical tests? We compare it with its predecessor, the HackRF One, and analyze improvements in RF characteristics.

He precisely controlled modulation and feedback loops ...

Arousal fluctuates continuously during wakefulness, yet how these moment-to-moment variations shape large-scale functional connectivity (FC) remains unclear. Here, we combined 7T fMRI with concurrent ...

Background/aims Posterior capsule opacification (PCO) is the most frequent long-term complication after cataract surgery, caused by proliferation of residual lens epithelial cells (LECs). Metformin, a ...
