Unfortunately yes, yes definitely, yes & yes, and yes.
Yes, if you look close, the paper is replete with error-filled generative reproductions of existing illustrations in the citations; including Fig. 6 (MC Escher struts), Fig. 7 (sprouting greeble tubes), and Fig. 8 (actuators replaced by tubes connected to mystery manifolds).
Even Fig. 2 shows the spike geometry magically changing, which is not addressed in the text and seems like an error carried over from the original illustration in the cited source.
Casts serious doubt on the credibility of the rest of the work.

CTRL+F “Deming” - Thank you. Organizations with vitality reason about the operation of the whole system, not simply the performance of actors in isolation.

SymPy: Symbolic Mathematics in Python 2 years ago
For great justice, does anyone know of any applications (other than Maple) that support WYSIWYG typeset input (not output) like Maple does?
As far as I know, Wolfram/Mathematica, LaTex, SymPy, Jupyter, Sage etc all rely on typewriter text for composing and inputting math. For this (and only this) reason, Maple is the only application that ever resonated with me, because input may be written in the same form it's written by hand, and it's baffling this capability isn't more commonplace. Is this a barrier to anyone else?
Commodity logic ICs ubiquitous and totally capable if needs are well-matched; it’s perhaps a deliberate prototype engineering/development choice.
From the paper:
Synchronous voltage pulses are sent to both the electrode of the strip connecting to the gate and drain electrodes of the MOSFET. The drain pulse is applied for around 1.1 ms at a constant voltage. The gate pulse starts at 40 μs after the drain pulse and ends at 40 μs before the end of the drain pulse.
the antigen-antibody complexes undergo stretching and contracting, akin to double springs, in response to a pulsed gate electric field. This motion across the antibody-antigen structure, corresponding to the pulse voltage applied on the test strip, induces an alteration in the protein's conformation, resulting in a time-dependent electric field applied to the MOSFET gate. Consequently, a springlike pattern emerges in the drain voltage waveform due to the external connection between the sensor strip and the MOSFET's gate electrode.
So they shake ‘em just so, and listen to the response…
ICs are perhaps variable timing & pulse-shaping logic?
First standout thing I noticed is the “patern generator” array of DIPs - admittedly without having dived into the paper, any answers from the hive mind what they’re doing?
