Jetson Nano更夸张：功耗6W，而整机电池（2200mAh 3S锂电）续航仅12分钟，且散热片体积超过机架空间。 我们最终选择ESP32-CAM（内置OV2640摄像头、4MB PSRAM）+ Arduino Nano V3.0（CH340G USB转串口芯片），原因很实在： ...

Cardiac myocytes isolated from patient-derived right atrial biopsies were subjected to workload transitions using patch-clamp stimulation and β-adrenergic stimulation (isoproterenol). In conjunction, ...
