Development of a 3D-CNN-based Prediction Model for Migration Barriers in Plasma-Wall Interactions

arXiv:2604.05521v2 Announce Type: replace Abstract: Understanding the long-term transport of hydrogen isotopes in plasma-facing materials, such as tungsten, is critical for the steady-state operation of magnetic confinement fusion reactors. However, dynamically updating the transition parameters for kinetic Monte Carlo (kMC) simulations as the atomic structure evolves under continuous plasma irradiation remains a severe computational bottleneck. Conventionally, calculating these migration...

House approves Ukraine aid package despite Republican objections

House approves Ukraine aid package despite Republican objections The legislation seeks to cement US assistance for Ukraine by providing more than $1 billion in aid - Bookmark - CommentsGo to comments The House of Representatives has approved legislation aimed at bolstering aid to Ukraine and imposing sanctions on key sectors of the Russian economy, despite objections from Republican leaders. These leaders warned that the bill could undermine ongoing negotiations for a more robust outcome....

Deep Learning-Accelerated Dynamic Kinetic Monte Carlo Simulation for Hydrogen Transport in Tungsten

arXiv:2606.02084v2 Announce Type: replace-cross Abstract: In magnetic confinement fusion reactors, hydrogen plasma irradiation causes material saturation and recycling, where hydrogen released from the tungsten wall significantly impacts the peripheral plasma. Kinetic Monte Carlo (kMC) simulations are essential for investigating the dynamic balance between incident and emitted fluxes at the atomic scale. However, standard kMC frameworks are inadequate for handling realistic material...

House Republicans push $70 billion immigration funding package toward passage

A monthslong stalemate over immigration enforcement could come to an end on Tuesday, as the U.S. House is poised to vote on a $70 billion funding package despite Democrats' vows to fight back. It's a major test for House Speaker Mike Johnson as he tries to cement one of President Donald Trump's top domestic priorities. Rep. Pete Aguilar, D-Calif., chair of the House Democratic Caucus, called the package a "$70 billion blank check for ICE and border patrol, with no strings attached."

House Republican Don Bacon says he wants 'pariah state' Russia booted from UN Security Council

House Republican Don Bacon has repeatedly called for Russia to be removed from the United Nations Security Council, labelling the nation a "pariah state." He has urged the UN General Assembly to vote on this removal, citing Russia's invasion of its neighbour and alleged crimes against humanity. Furthermore, Bacon has advocated for increased US military aid to Ukraine and the passage of Russian sanctions.

GOP senators rally around new DHS proposal targeting sanctuary cities: 'Should pay a price'

Republican senators signaled support for imposing consequences on sanctuary cities after Homeland Security Secretary Markwayne Mullin floated a proposal to pull Customs and Border Protection (CBP) officers from airports in jurisdictions that refuse to cooperate with federal immigration authorities. "I think there should be consequences to cities and states that undercut federal law," Sen. Lindsey Graham, R-S.C., told Fox News Digital. "I think they should pay a price for what they do.

Republicans defy Johnson to advance Democrat-backed Ukraine aid

House Democrats scored a rare victory on Wednesday after the chamber voted to advance a security package providing new military aid for Ukraine and imposing steep sanctions on Russia. The Democrat-sponsored legislation cleared a procedural vote 218-204 with all Democrats present voting in the affirmative. Seven members of the House Republican conference supported the measure in a notable display of defiance against GOP leadership.

House Republican Don Bacon says he wants 'pariah state' Russia booted from UN Security Council

House Republican Don Bacon has repeatedly called for Russia to be removed from the United Nations Security Council, labelling the nation a "pariah state." He urged the UN General Assembly to vote on Russia's expulsion, citing its invasion of a neighbour and alleged crimes against humanity. Furthermore, Bacon advocated for increased US military aid to Ukraine and the passage of further Russian sanctions.
