If you’re still at M&M, I’ll be talking on behalf of the fantastic @amirafsharm this afternoon at 4:45 in room 10 :)

[Dr Alex Robinson @AlexRobinson212]

@ColinOphus @StephanieRibet Amazing! So well deserved, your talk was fantastic today!!

[Dr Alex Robinson @AlexRobinson212]

@g_varnavides @StephanieRibet @ColinOphus This is a fantastic paper! Well done guys 👍🏻

Made a basic MATLAB app to look at the way dose is distributed in STEM. The novelty being that a realistic STEM probe can be constructed, allowing for the calculation of dose for defocused probe STEM experiments. The app also supports sub-sampling strategies!

Thanks to my good friend @amirafsharm for providing the very handy adjustable scale bar!

then it will inpaint a defect, if it doesn’t sample a defect, then it won’t inpaint a defect. BPFA is not a generative algorithm, it simply infers what an individual patch is most likely to look like given the observation and parameters of the recovery.

[Dr Alex Robinson @AlexRobinson212]

A common question that gets asked when presenting the BPFA for CS-STEM is, “what happens when you try to inpaint a defect?”, well here is the answer- it inpaints a defect!

Model taken from Wang et. al. (2020)

[Dr Alex Robinson @AlexRobinson212]

The reason is because the BPFA operates on a single patch at a time, and each of these patches is independent, knowing nothing about the global structure other than what is in the dictionary. If the sampling operator (mask) samples a defect…

Busan is good for MICE (and Guinness)

@g_varnavides This is brilliant, Georgios!

[Amirafshar @amirafsharm]

Today at 14:35 (Seoul time), I will talk about a new phase retrieval algorithm for compressive electron ptychography, at #imc20, room 105. Feel free to attend if you are around. Joint work with @AlexRobinson212, A. Velazco, A. kirkland, and N. browning.

[Amirafshar @amirafsharm]

Glad that my poster acheived the second place in the #MM2023 poster prize. Thanks to @AlexRobinson212 for excellent presentation of the poster. Other collaborators are Abner Velazco-Torrejon and Angus Kirkland from @RosFrankInst and Nigel Browning @RUEDI_UK

@JHNaismith @RosFrankInst @QDetectors @STFC_Matters Thanks Jim and RFI for the great collaborations so far! If anyone wants to discuss SenseAI, can you point them in my direction?
