📢BREAKING: Just left the courthouse for our NIH grant termination case
Judge ruled terminations are “VOID & ILLEGAL”
As a plaintiff, I felt a wave of relief & hope; he acknowledged the discrimination & harm
Closed by asking, ‘Have we fallen so low? Have we no shame?’

Plug for my lab’s open source commutator designed for compatibility with electrical I/O, an accessible through-hole for non-electrical tethers, and low-noise active rotation. I have gotten great performance out of it and recommend it to anyone needing a commutator!

Microscopy produces images, but images are not always what we want. With collaborators at Duke and HHMI, we show that optical tricks can transfer more information from the sample to the camera, and then, algorithms retrieve publishable data. www.spiedigitallibrary.org/journals/neu...
Compressive streak microscopy for fast sampling of fluorescent reporters of neural activity
SignificanceIn vivo one-photon fluorescence imaging of calcium and voltage indicators expressed in neurons enables noninvasive recordings of neural activity with submillisecond precision. However, data acquisition speed is limited by the frame rate of cameras.AimWe developed a compressive streak fluorescence microscope to record fluorescence in individual neurons at high speeds (≥200 frames per second) exceeding the nominal frame rate of the camera by trading off spatial pixels for temporal resolution.ApproachOur microscope leverages a digital micromirror device for targeted illumination, a galvo mirror for temporal scanning, and a ridge regression algorithm for fast computational reconstruction of fluorescence traces with high temporal resolution.ResultsIn simulations, the ridge regression algorithm reconstructs traces of high temporal resolution with limited signal loss. Validation experiments with fluorescent beads and experiments in larval zebrafish demonstrate accurate reconstruction with a data compression ratio of 10 and accurate recordings of neural activity with 200- to 400-Hz sampling speeds.ConclusionsOur compressive microscopy enables new experimental capabilities to monitor activity at a sampling speed that outpaces the nominal frame rate of the camera.

What incentives do you have as faculty to set high standards and not give a free A to all your students ? i just saw one of my colleagues -who is a much better teacher than me- get trashed with nonsensical claims on ratemyprofessor, in a class that I taught too, probably by students who got a B.

Looking at the last 10 emails I received from students taking my class I can see similar GPT-like phrasing across 5 of them. LPT, a short, personal email, even filled with your human typos is far more appreciated than any of the LLM diarrhea you force me to read.
