Our eFIB-SEM (as per Xu et al. 2017 https://elifesciences.org/articles/25916 ) runs 24/7 for up to 8 weeks, when it runs out of source. And it's essential that it does so, uninterrupted, since it's imaging at nanometre resolution, milling 2 nm slices at a time with an ion beam and then repeatedly imaging the block face. The process is unsurprisingly very sensitive; was hard enough to overcome the reheat cycle of the instrument itself (every 60 hours or so) by detecting it, de-engaging the beams and then seamlessly re-engaging with the block face.
A brief video of the kind of data we acquire:

Das #Lichtsteuergerät SL 3930 wurde um 1988 im VEB Starkstrom-Anlagenbau #Leipzig #Halle #VEM als Ergänzung zur gleichnamigen #HiFi Kombination produziert. Das Gerät kombiniert ein Lauflicht-Steuergerät mit einer klassischen #Lichtorgel. Über die rückseitigen Schuko-Steckdosen können insgesamt 4 Strahler angeschlossen werden. Das #RFT SL 3930 folgte dem bereits in #Berlin produzierten #AKA #Lichteffektgerät.
Die ausführlichen Beschreibungen habe ich unter 🏳️🌈 https://rk7.de/hifi 🏳️🌈 hinterlegt.😊 -
Happy to be involved in UNICIL, our new Wellcome Trust Discovery project coordinated by @micromotility.bsky.social
We will study ciliary dynamics across scales and organisms. A long-term #postdoc position will be available at Heidelberg University @uniheidelberg shortly.

Thanks for sharing this – will have to think about it. In our case, we built in-house the gridtape reel holders which amount to a custom stage with a mini-camera in it for identifying slots and controlling imaging. So we don't use the factory-supplied stage.

True as always that the way to make software run faster is to make it do less operations. After all, CPUs can only execute a fixed number of operations per unit of time.
Here, I tweaked code for serial section registration that drops execution time from 27 seconds to 100 milliseconds: a 270x speed up.
All it had to do is to search for matching SIFT features in one image only within a predetermined radius centered on one SIFT feature in another image. Extremely effective for when e.g., the maximum translation is known.
The matching code using a KDTree:

From Moritz Helmstaedter on #RoboEM:
"In today’s AI research, any project lasting longer than 6 months is considered slow, if not outdated and overrun by history. RoboEM, with a concept and an approach that seem quite plausible, still took 5 years from idea to the fully evaluated tool reported here. This was only possible with the patient support of the Max Planck Society, which encourages long-term projects, and the tenacity of the first author. Details made all the difference. And, as often, dead ends had to be avoided efficiently. We had to abandon, for example, the idea of using steering variability to indicate branch points — a nice analogy to road intersections in car steering, but too far-fetched to work well enough in brain tissue data. Sometimes giving up beloved ideas is as important as following through on others. M.H."

"SmartEM: machine-learning guided electron microscopy" by Meirovitch et al 2023 (Nir Shavit and Aravi Samuel labs)
https://www.biorxiv.org/content/10.1101/2023.10.05.561103v1.abstractTurn up the imaging rate of your scanning electron microscope by only imaging at high resolution the areas of the image necessary to resolve ambiguities in the low-res image. Motivated by the need for high-throughput but inexpensive imaging for #connectomics.
