Hi, it's former Social Security Commissioner Martin O’Malley.
I have some exciting news. 
My organization,
Win Back Our Country,
is ramping up our efforts to protect Social Security.
And I want you to be a part of it!
Here’s our plan:
✅ Fact-check Trump and Musk’s lies and shine a spotlight on their actions. 
📢 Organize local grassroots and earned media events to hold Trump accountable. 
🎯 Target ads to persuadable voters explaining w…

We are barely 6 months into #TheAmericanFascist Presidency and we already find ourselves with fundamental rights in the American Constitution under direct threat and the power of the judiciary to enforce and check the power of the President being pulled back.
And Democratic Party members seem to be all talk and very very little action or leadership to counter this.
Are they waiting for the midterms to take back Congress?
At this pace, surely they see the risk that there may not BE midterms. Or that the results are negated, disputed or invalidated.
I can’t fathom how they are not removing themselves from Congress now in protest and calling for a general protest/strike of all freedom loving Americans to restore the constitution, force the Trump appointed fascist enabling judges to resign, and force Trump and his Administration to go.
July 4th is coming. Independence Day? Or not? Democracy or not?

Pre-training for Recommendation Unlearning
Modern recommender systems powered by Graph Neural Networks (GNNs) excel at modeling complex user-item interactions, yet increasingly face scenarios requiring selective forgetting of training data. Beyond user requests to remove specific interactions due to privacy concerns or preference changes, regulatory frameworks mandate recommender systems' ability to eliminate the influence of certain user data from models. This recommendation unlearning challenge presents unique difficulties as removing…

Removal of spallation-induced tritium from silicon through diffusion
Tritium, predominantly produced through spallation reactions caused by cosmic ray interactions, is a significant radioactive background for silicon-based rare event detection experiments, such as dark matter searches. We have investigated the feasibility of removing cosmogenic tritium from high-purity silicon intended for use in low-background experiments. We demonstrate that significant tritium removal is possible through diffusion by subjecting silicon to high-temperature (> 400C) baking. Usi…
