Approximate Proximal Operators for Analog Compressed Sensing Using PN-junction Diode
In order to realize analog compressed sensing, the paper considers approximate proximal operators of the $\ell_1$ and minimax concave penalty (MCP) regularization functions. Specifically, we propose to realize the approximate functions by an electric analog circuit using forward voltage-current (V-I) characteristics of the PN-junction diodes. To confirm the validity of the proposed approach, we employ the proposed approximate proximal operators for the $\ell_1$ and MCP regularization functions …

Okay, initial thoughts on the Thinkpad P14s Gen 6:
- The laptop is better behaved thermally and noise-wise than the X1C with the Intel Core 155U.
- The CPU and GPU seem to be sipping power (3W/3W) which is nice. I haven't punched the CPU yet with something like a vicious `ffmpeg` AV1 encode.
- Replacing RAM/NVMe isn't too painful, the screws in the bottom case of the laptop are captive. Still have to deal with some plastic clips.
- The screen is fine, nothing to…

So, initial thoughts so far on the Clockwork uConsole:
- The trackball is pretty bad, would classify it as barely functional.
- Wifi does not work which severely limits things...maybe an antenna problem? Verified it was securely installed on the CM4 module.
- Install isn't bad, very solid device.
- The thermal pad for the RPi CM4 is waaaay too thick.
