Complexity of learning matchings and half graphs via edge queries
The problem of learning or reconstructing an unknown graph from a known family via partial-information queries arises as a mathematical model in various contexts. The most basic type of access to the graph is via \emph{edge queries}, where an algorithm may query the presence/absence of an edge between a pair of vertices of its choosing, at unit cost. While more powerful query models have been extensively studied in the context of graph reconstruction, the basic model of edge queries seems to …

Two-loop renormalisation of quark and gluon fields in the SMEFT in the on-shell scheme
We compute the contributions of CP-conserving dimension-six SMEFT operators to the two-loop renormalisation constants of quark and gluon fields in the on-shell scheme. Specifically, we consider the top-quark chromomagnetic operator and the triple gluon operator. We also compute the contribution of four-quark operators to the gluon renormalisation constant and discuss the implications for the running of the strong coupling constant.

Good article summarizing a lot of things relevant to continued COVID'19 caution:

Key points:
COVID'19 weakens the immune system:
"""
So it's not just about infecting you and causing respiratory illness and fever and all of the things that we usually get with the viral infection. This virus also specifically causes your immune system to become weaker.
"""
It damages blood vessels:
"""
In addition to SARS-CoV-2's ability to dysregulate the immune system and suppress the immune system, the spike protein itself is very damaging to blood vessel structures as well as red blood cells and platelets themselves.
"""
The folk idea that infections make our immune system stronger and stronger like a muscle just isn't true (or at least, doesn't apply to COVID'19 because of how, unlike most other viruses, it damages the immune system):
"""
For the longest time in the field of immunology, there was the sort of adage that your immune system needs to be tested every now and again to stay strong. That's an old-fashioned idea.
The more new-fashioned and evidence-based idea is that, although your immune system can take on [a COVID] infection, you want to avoid testing it as much as possible because your body is sustaining damage with each infection that it survives.

Raqlet: Cross-Paradigm Compilation for Recursive Queries
We introduce Raqlet, a source-to-source compilation framework that addresses the fragmentation of recursive querying engines spanning relational (recursive SQL), graph (Cypher, GQL), and deductive (Datalog) systems. Recent standards such as SQL:2023's SQL/PGQ and the GQL standard provide a common foundation for querying graph data within relational and graph databases; however, real-world support remains inconsistent across systems. Raqlet bridges this gap by translating recursive queries acros…

After seeing signal reports from DP0GVN for ages (they typically leave an FT8 station running as an RBN monitoring station), I finally was at my radio when there was an operator at theirs. Always excited about an Antarctica QSO, even on FT8!

Comparison of chiral limit studies in curvature mass versus on-shell renormalized quark-meson model using ChPT
Consistent chiral limit has been investigated in the curvature mass parametrized quark-meson (QM) model with the quark one-loop vacuum term (QMVT) employing the infrared regularized Chiral perturbation theory (ChPT) predicted scaling of the pion,~kaon decay constants $f_π, f_{K} $ and $M_η^2 = m_η^2 + m_{η^{\prime}}^2 $ when the $π\ \text{and} \ K $ meson masses are reduced as one moves away from the physical point in the Columbia plot.~Comparing the QMVT model Columbia plots with the corr…

Modelling top-quark decays in $t\bar{t}t\bar{t}$ production at the LHC

Modelling top-quark decays in $t\bar{t}t\bar{t}$ production at the LHC
We compare the fixed-order NLO QCD predictions for the $pp\to t\bar{t}t\bar{t}+X$ process in the $4\ell$ decay channel with the parton-shower based results obtained with the POWHEG and MC@NLO matching methods. In the first case, NLO QCD corrections are consistently included in both the $t\bar{t}t\bar{t}$ production step and the decays of the four top quarks, preserving all spin correlations. In the second approach, higher-order effects in top-quark decays with approximate spin correlations are …

A background-free signal of jet-induced diffusion wake in quark-gluon plasma
Rapidity asymmetry of jet-hadron correlation has been proposed as a robust signal of dijet-induced diffusion wake in quark-gluon plasma in high-energy heavy-ion collisions. We generalize this observable to other jet configurations such as γ/Z0-jets and propose a new method to compute the rapidity asymmetry that is free of background. In this new method, the rapidity of the trigger is fixed or restricted to a symmetrical range while the rapidity of the associated jet is varied. The rapidity asy…
