Effective description of Nelson-Barr models and the theta parameter
Nelson-Barr theories solve the strong CP problem with CP spontaneously broken at Λ_{CP} and transmitted to the CP conserving version of the SM through vector-like quarks (VLQs). For an arbitrary number of CP breaking scalars and VLQs, we perform the full one-loop matching calculations at Λ_{CP} up to dimension five operators and the relevant matching calculations at the VLQ scale relevant to tracking the contributions to the parameter \barθ. In the EFT after the CP breaking scalars have been…

Ich bin an dem Punkt, wo ich einfach gern eine halbwegs funktionierende freiheitlich-demokratische, rechtsstaatliche Regierung hätte. Wo diese mit meinen persönlichen Überzeugungen und Vorstellungen übereinstimmt, ist mir inzwischen (beinahe) egal.

On the Dynamics of Weighted Composition Operators
We study the properties of power-boundedness, Li-Yorke chaos, distributional chaos, absolutely Cesàro boundedness and mean Li-Yorke chaos for weighted composition operators on $L^p(μ)$ spaces and on $C_0(Ω)$ spaces. We illustrate the general results by presenting several applications to weighted shifts on the classical sequence spaces $c_0(\mathbb{N})$, $c_0(\mathbb{Z})$, $\ell^p(\mathbb{N})$ and $\ell^p(\mathbb{Z})$ ($1 \leq p < \infty$) and to weighted translation operators on the classica…

Calamus 23 This moment as I sit alone
A promise of global unity, Whitman sharing his adulation for men in other countries.
I guess this is an antidote to Whitman's nationalism? His celebrations of America seem sweet and sincere but they are very American-centric. Here he's explicitly saying men of other lands can be just as wise, beautiful, or benevolent as American men. It seems unusual that he feels he has to say it explicitly.
As for the queer reading, his conclusion is
I know we should be brethren and lovers
There's that word, "lovers". It's so brash it's hard to understand. It seems uncharacteristically direct even understanding Whitman as a gay poet. Maybe this is some 19th century romantic language, mixing what feels very gay in with a more general celebration of brotherhood? Or maybe it is literally what it says, Whitman eroticizing international men.

The NASA Exoplanet Archive and Exoplanet Follow-up Observing Program: Data, Tools, and Usage
The NASA Exoplanet Archive and the Exoplanet Follow-up Observing Program service are two widely used resources for the exoplanet community. The NASA Exoplanet Archive provides a complete and accurate accounting of exoplanetary systems published by NASA missions and by the community in the refereed literature. In anticipation of continued exponential growth in the number of exoplanetary systems, and the increasing complexity in our characterization of these systems, the NASA Exoplanet Archive ha…

Classification of aut-fixed subgroups in free-abelian times surface groups
In this paper, we are concerned with the direct product $G=π_1(Σ)\times \Z^k$ for $Σ$ a compact orientable surface with negative Euler characteristic, and give a complete classification of its fixed subgroups of automorphisms. As a corollary, we show that $G$ contains, up to isomorphism, infinitely many fixed subgroups of automorphisms if and only if $k\geq 2$, which is a contrast to that of hyperbolic groups. As an application on Nielsen fixed point theory, we provide a family of aspherical…

Mountainhead is good TV. An exaggeration of white tech bro culture, a story about an AI apocalypse, made by Jesse Armstrong (of Succession fame). The real surprise is how good Cory Michael Smith is in the lead role.

Calamus 22 Passing stranger!
An absolutely smoldering poem of unfulfilled desire from a casual encounter. It is delicious for its clear and direct explication of a very complicated emotion. The hottest line:
You give me the pleasure of your eyes, face, flesh, as we pass
The poem manages to capture three things in just ten lines.
Whitman is generously pan-gender but the text still feels queer-coded to me. Specifically in how the desire is kept secret: "I am not to speak to you... I am to wait". Combined with the street-cruising scenario (a theme in previous poems) and I can definitely relate to my gay experience.
