Global QCD analysis of spin PDFs in the proton with high-$x$ and lattice constraints
We perform a comprehensive global QCD analysis of spin-dependent parton distribution functions (PDFs), combining all available data on inclusive and semi-inclusive deep-inelastic scattering (DIS), as well as inclusive weak boson and jet production in polarized $pp$ collisions, simultaneously extracting spin-averaged PDFs and fragmentation functions. Including recent Jefferson Lab DIS data at high $x$, together with subleading power corrections to the leading twist framework, allows us to verify…

Evaluation of Nuclear Microreactor Cost-competitiveness in Current Electricity Markets Considering Reactor Cost Uncertainties
This paper evaluates the cost competitiveness of microreactors in today's electricity markets, with a focus on uncertainties in reactor costs. A Genetic Algorithm (GA) is used to optimize key technical parameters, such as reactor capacity, fuel enrichment, tail enrichment, refueling interval, and discharge burnup, to minimize the Levelized Cost of Energy (LCOE). Base case results are validated using Simulated Annealing (SA). By incorporating Probability Distribution Functions (PDFs) for fuel cy…

Who is realistically going to carry around a second digital camera with them? Of course cameras are better than smartphones, but the best camera is the one you have with you at the moment.
I've taken thousands of photos that I never would have thanks to my iphone.

PDFs had a rough month, with one study crediting them for 15% of cyberattacks and Meta flubbing PDF redactions to leak rivals’ secrets in court. It's possible to make PDFs secure but easy to get burned https://www.linkedin.com/posts/jonippolito…

Toolbox for children in return - Publications Office of the EU
Addressing the return of unaccompanied minors or children within families is a delicate matter that demands a humane approach. This approach must not only respect fundamental rights but also prioritise the child's best interests. Additionally, clear and comprehensive information about the return procedures is essential for those involved, enabling them to prepare as effectively as possible. One of the primary objectives of Frontex is to assist MS throughout all stages of the return procedures. …

Theoretical Summary: Moriond QCD and High-Energy Interactions 2025
The theory talks at Moriond QCD and High-Energy Interactions 2025 covered the full range of scales from BSM, top, Higgs, EW, and hard QCD physics, through resummation, factorisation, and PDFs, to hadronic, heavy-ion, nonperturbative, and lattice QCD. A few talks also touched on methodologies. We here summarise main points of most of these contributions.
