I am pleased to see this paper published. Thanks to @MdMobasshirRas1 for leading data analysis which he started right after Hurricane Ian, 2 yrs ago. We just had a hurricane which caused mass evacuation in Florida. ascelibrary.org/doi/10.1061/…

Excited to share our #NeurIPS2025 paper 🎉
"more thinking ≠ better reasoning"
👉 We uncover the 𝐦𝐢𝐫𝐚𝐠𝐞 𝐨𝐟 𝐭𝐞𝐬𝐭-𝐭𝐢𝐦𝐞 𝐭𝐡𝐢𝐧𝐤𝐢𝐧𝐠 𝐬𝐜𝐚𝐥𝐢𝐧𝐠: increasing thinking tokens at test-time boosts accuracy briefly, then hurts as response variance increases
Rest in peace Prof. Mahmassani (@b_rational) who was a great scholar and a great person. Transportation community will miss you for a long time.
We are deeply saddened to share the passing of Dr. Hani Mahmassani, director of NUTC, esteemed professor, and global leader in transportation research. His impact was profound and lasting. Read more: mccormick.northwestern.edu/n…

AI will accelerate progress in some scientific fields. AI will reduce the barriers to enter to science. It will give access to literature and accelerate coding and writing. More people from developing countries will participate. They will publish new (and great) ideas.
One of the biggest areas of AI hype right now is the notion that it will hyperaccelerate scientific progress. I understand why people think this — AI is already accelerating scientific production. But the big problem is that production seems to have gotten decoupled from any useful measure of progress a long time ago. There is a whole science-of-science literature hand wringing about the fact that scientific production has increased ~exponentially but progress has not accelerated and has even slowed down.
Producing papers, for the most part, is a game researchers must play for status and career progress. It's value is relative. It's like thinking that AI is going to help traders make a lot more money. If everyone has access to the same capabilities, there is no alpha.
There's also the fact that in many/most fields, there's a limit to AI's impact on production as well. It may be able to do the cognitive parts but the bottleneck may experiments on humans or some other form of real-world interaction that's hard to automate.

As extreme storms seemingly make the once-trusted model obsolete, experts weigh what data should inform future risk calculations to bolster resiliency. Read more on the #ASCESource: go.asce.org/3NZigbq.

I really enjoyed taking with @umairfan about emergency management and disasters. Thanks for your interest in this timely issue. @spaucf @UCFCCIE @UCF
An interesting point that @DrEcoclaire raised was you don't just have to prepare for getting hit by disasters like hurricanes; you need to be ready to receive people from nearby afflicted regions.
Otherwise, it could create a disaster within a disaster.

Orange and Seminole county's electricity grid is very resilient.
Over 3.3 million electric customers are without power in #Florida due to #HurricaneMilton.

To help facilitate evacuations for #HurricaneMilton, Emergency Shoulder Use (ESU) plans are actively being put in place for Eastbound I-4 and portions of Northbound I-75. Law enforcement and signage will alert motorists on when to enter and exit the shoulder. Learn more about ESU by watching this video: bit.ly/3YbhTAi
Last year I gave a 10-min talk at UCF on how rapidly intensifying hurricanes can complicate everything from evacuation to infrastructure disruption. These are some critical things for emergency management officials to consider. #HurricaneMilton youtube.com/watch?v=s10CS8wH…
How to quantify recovery from a hurricane in near real-time? Our paper, "Understanding the loss in community resilience due to hurricanes using Facebook Data" can answer this question. sciencedirect.com/science/ar…
