Portal: completed, again
Steam was released for the Mac in the last week, and as part of the initial offer you can get Portal for free. In fact, I'd get Portal for free anyway, because they're saying that if you bought it for PC, they consider you bought it for Mac as well. Very generous of them. So I've completed Portal's main story for the fourth time (PC, PC with commentary, Xbox 360, Mac).

Gamma-Rays and Gravitational Waves from Inelastic Higgs Portal Dark Matter
We explore a simple and predictive dark matter scenario involving a complex scalar field, $ϕ$, coupled to the Higgs portal with no additional field content. In the UV, the field possesses a global $U(1)$ symmetry which is broken by mass terms and Higgs portal interactions. In the mass basis, the complex field splits into a pair of real scalars with a small mass splitting (in analogy to pseudo-Dirac fermions), such that the Higgs portal acquires both diagonal and off-diagonal terms with respect…

Going out for some pond building parts but had to take a break at the cΓuumaʕas river (su-u-ma-as) to watch the fishers coming in from a morning of sockeye salmon fishing. 🎣
Lots of sounds of Bald Eagles in the distance. Probably in the trees across the river looking for a fish to snatch up.
check out the pro trailer parking with the offset stalls. 😂 🅿️

Canonical partial ordering from min-cuts and quantum entanglement in random tensor networks
The \emph{max-flow min-cut theorem} has been recently used in the theory of random tensor networks in quantum information theory, where it is helpful for computing the behavior of important physical quantities, such as the entanglement entropy. In this paper, we extend the max-flow min-cut theorem to a relation among different \emph{partial orders} on the set of vertices of a network and introduce a new partial order for the vertices based on the \emph{min-cut structure} of the network. We appl…

Character theoretic techniques for nonabelian partial difference sets
A $(v,k,λ, μ)$-partial difference set (PDS) is a subset $D$ of size $k$ of a group $G$ of order $v$ such that every nonidentity element $g$ of $G$ can be expressed in either $λ$ or $μ$ different ways as a product $xy^{-1}$, $x, y \in D$, depending on whether or not $g$ is in $D$. If $D$ is inverse closed and $1 \notin D$, then the Cayley graph ${\rm Cay}(G,D)$ is a $(v,k,λ, μ)$-strongly regular graph (SRG). PDSs have been studied extensively over the years, especially in abelian groups, w…

Notes on the cohomology of partial Hessenberg varieties
Hessenberg varieties are a family of subvarieties of full flag varieties. This family contains well-known varieties such as Springer fibers, Peterson varieties, and permutohedral varieties. It was introduced by De Mari-Procesi-Shayman in 1992 and has been actively studied in this decade. In particular, unexpected relations to hyperplane arrangements and the Stanley-Stembridge conjecture in graph theory have been discovered. Hessenberg varieties can be defined in partial flag varieties. In this …

A Model-Based Derivative-Free Optimization Algorithm for Partially Separable Problems
We propose UPOQA, a derivative-free optimization algorithm for partially separable unconstrained problems, leveraging quadratic interpolation and a structured trust-region framework. By decomposing the objective into element functions, UPOQA constructs underdetermined element models and solves subproblems efficiently via a modified projected gradient method. Innovations include an approximate projection operator for structured trust regions, improved management of elemental radii and models, a …

I've updated my “TIL: What to Do If a Beryl AX Can’t Connect to a Wi-Fi” because a while ago I realized that choosing DFS channels for 5 GHz make the booting take more than 5 minutes.

What to Do If a Beryl AX Can’t Connect to a Wi-Fi
I’m absolutely in love with my GL.iNet GL-MT3000 (Beryl AX), but occasionally, it has trouble connecting to captive portal Wi-Fis.
