However, splitting the RSA computation into two steps may lead to information loss. A single-step approach using regression or hierarchical modeling appears to improve precision, reliability and interpretability in estimating representational similarity. arxiv.org/abs/2511.00395
Is Representational Similarity Analysis Reliable? A Comparison with Regression
Representational Similarity Analysis (RSA) is a popular method for analyzing neuroimaging and behavioral data. Here we evaluate the accuracy and reliability of RSA in the context of model selection, a...

As ranking Dem and former chair of the House Armed Services Committee, he usually stays in his lane because you save your powder for the defense fights.

When he lays it out like this, we should listen /2
So that's the second thing that a president has: Article II, the inherent right of self-defense. If somebody is about ready to launch missiles at the U.S. or launch an attack, the president does have the authority to strike those people. Drug runners do not qualify for that. And I know —drugs kill-and they do. They kill tens of thousands of people. But it is not the intention of the drug runners to kill people. They're selling drugs, and drugs are a major problem in this country. I happen to think it's as much of a demand problem as it is a supply problem-but it is not a direct attack to try and kill Americans or seize territory in America. And it sure as hell isn't that on a boat off the coast of Venezuela that is thousands of miles from the U.S. And that's the other thing-they haven't presented a shred of evidence that those boats were even headed to the United States. Smith: Yeah and also understand the other connection, as you've seen the stories about Trump authorizing CIA action in Venezuela. I have no independent confirmation of that other than what I've read in the media. And as you see the rhetoric from him ramp up about the Maduro regime in Venezuela, is this really about stopping drugs or is he engaged in a regime change effort in Venezuela, which certainly hasn't been approved of by Congress and certainly doesn't fall under the Article II designation. Trump has mused about how now maybe they may bo hitting targets on land within Venezuela. So he is asserting the unilateral right to start a war with Venezuela Smith: I've not been briefed. I don't know if I'd go so far as, I expect war. But if we, as a country, don't stand up and say, no, President Trump, you do not have the unilateral power to override the Constitution and do whatever you want whenever you want whenever you want to do it-Trump's just going to keep expanding. And look, I'll tie a little terrifying connection in for you here. You hear what's going on in Chicago—and it's going on in other cities as well—but in Chicago, most blatantly, they are literally stopping people on the street and demanding their papers. If they don't have them-frequently citizens, legal residents— are being detained by your United States federal government without any probable cause, articulable suspicion, or any measure, just because they showed up and they want to say it. They are violating our rights individually, and then Trump is asserting his right to use the United States military in any way that he sees fit— certainly in the Caribbean, but also right here in the United States of America. He's trying to send them to Portland, trying to send them to Chicago. How far are we away from President Trump deciding to use the U.S. military to do a kinetic strike on people within the U.S. because he sees them as a threat, by whatever definition he wants to throw out there? I want to say-and I know there's a lot of people on the left and in the Democratic Party who are all over this— but I want to say to the rest of you who are not: come on. I mean, you could not like the Democrats, you could not like a bunch of our policies. Hell, you can oppose the Affordable Care Act, you can oppose a bunch of other things. If you are an American conservative, do you want the federal government to be able to have that type of power-to take away your liberty-whether it's Trump or anybody else?

DOE's public statements about this say that all the ad hoc committees, including HEPAP, will be replaced by a single committee. As an STS researcher, I am compelled to point out that this overlaps with the Nazi playbook for taking over German physics. My slides about how they did that:🧪⚛️🔭
