Abstract

fetched live from OpenAlex

Using a relatively low-acceleration-voltage (a few tens of kilovolts) electron beam, we are researching diffractive imaging to achieve atomic-resolution observation with little damage to the specimen. Using the prototype microscope, we verified the reconstruction of the object image of a multiwall carbon nanotube (MWCNT) [1]. In this prototype, the resolution during specimen observation was not sufficiently high, and the camera length was fixed. To achieve high resolution imaging using the diffraction pattern with a variable camera length, we have developed a new diffraction microscope based on the conventional scanning electron microscope (Fig. The diffraction pattern is recorded on the imaging plate (IP) without projecting the back-focal plane. Development of the new microscope and examples of diffractive imaging will be presented.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
