Autonomous driving could become one of the most tangible examples of AI improving everyday life.
The real value of the Tesla Cybercab isn’t just getting from A to B. It’s giving people their time back. Work, rest, read, watch a movie, or simply enjoy the ride. Our commute becomes our time again!
Perhaps one of AI greatest contributions won’t be replacing what humans do, but freeing us from repetitive tasks so we have more time to live, create, and connect. Everything is bigger in Texas!

I’m pleased to share that the MIRD Pamphlet No. 34, Part 1: MIRDct—A Customizable Software Tool for CT Dosimetry has now been published in the Journal of Nuclear Medicine:
https://t.co/cvwzGKTSHY

This publication follows the release of the MIRDct software (https://t.co/llwodggYSs) and provides a comprehensive description of this new organ-level tool for CT dosimetry, based on mesh-type computational phantoms.

This is a collaborative effort and part of the community platform (https://t.co/ot5AgKqLfs) for dosimetry in nuclear medicine, computed tomography, and hybrid imaging. Many thanks to all collaborators and colleagues at MSKCC and UF, and the MIRD Committee, for their invaluable contributions to this work.

Co-authors: Cameron Kofler, Robert Dawson, Jared Baggett, Laura E. Dinwiddie, Sean J. Domal, Lukas M. Carter, Harry Marquis, Gunjan Kayal, Pat B. Zanzonico, Wesley E. Bolch and Adam L. Kesner.

Nuclear Energy is safe and green, way to go! 🤠⚛️

[Greg Abbott @GregAbbott_TX]

Texas is the energy capital of the world.

We’re ready to be #1 in advanced nuclear power. Today, we released our plan to build that industry in Texas.

By utilizing advanced nuclear energy, we’ll enhance the reliability of our state grid & provide affordable, dispatchable power.

Nice paper: "Specific absorbed fractions & radionuclide S-values for tumors of varying size & composition"; Olguin et al.:
https://t.co/5uq82X2UVX
e.g. in Table 7C, they show that S-values for Lu-177 as a function of sphere radius (r) scales by A*r^(-2.96).
