I just got email from Delta Airlines. As of October of this year, flying economy earns you zero frequent flyer miles.
That's fine, it just means that I have to discount competing brands by 5% or something when comparing, since (for instance) economy on JetBlue *will* give me miles (points).

‘Net Zero is a Killer’: Meet Reform UK’s New Chair David Bull
Reform UK’s new chairman has repeatedly attacked climate targets as “madness” and “a killer”, supported fracking, and falsely dismissed the role of carbon emissions on heatwaves. David Bull, a TalkTV presenter and former doctor, was appointed as the chair of Nigel Farage’s right-wing populist party this week following the resignation of its previous chair Zia Yusuf. […]

Initial ideal of a general rational or elliptic curve on quadrics
Over an algebraically closed field of characteristic zero, we prove that the generic initial ideal with respect to the degree reverse lexicographic term order of a general rational or elliptic curve on quadrics is almost revlex. Following constructive arguments, our proof combines features of a pencil of quadrics, interpolation methods and the notion of double generic initial ideal.

Effects of rough boundary and nonzero boundary conditions on the lubrication process with micropolar fluid
The lubrication theory is mostly concerned with the behavior of a lubricant flowing through a narrow gap. Motivated by the experimental findings from the tribology literature, we take the lubricant to be micropolar fluid and study its behavior in a thin domain with rough boundary. Instead of considering (commonly used) simple zero boundary condition, we impose physically relevant (nonzero) boundary condition for microrotation and perform asymptotic analysis of the corresponding 3D boundary valu…

Geometric Optimization and IPA-Induced Dispersion Tuning in Solid-Core Photonic Crystal Fibers
This study presents a numerical investigation of solid-core photonic crystal fibers with circular and hexagonal cladding geometries. The goal is to optimize optical parameters for nonlinear photonics and environmental sensing. Full-vectorial simulations using FDTD, PWE, and FDE are used to analyze the effects of core diameter, pitch, and air filling fraction on the zero-dispersion wavelength, nonlinear coefficient, effective mode area, and confinement loss. Reducing the core diameter from 2.4 t…

Rambo¹ ist die Geschichte eines aus dem verlorenen Vietnamkrieg zurückkehrenden Veteranen, den zu Hause niemand mehr haben will und von der Polizei² eingesperrt und gedemütigt wird – was letztlich dazu führt, daß er die ganzen „wir wollen hier keine Fremden“-Typen aufmischt.³
Werden heute in den USA Veteranen einfach so verhaftet, geht das anders aus – ist ja schließlich kein Action-Film.

Unlocking Altermagnetism in Antiferromagnetic 2D Films via Adsorption
Altermagnets, characterized by zero net magnetization and momentum-dependent spin splitting, have recently garnered significant attention due to their potential applications in a variety of fields. Here, we propose a symmetry-engineering strategy to unlock altermagnetism in two dimensional (2D) antiferromagnetic systems via surface adsorption of atoms or molecules. By employing spin group theory, we systematically demonstrate that selectively breaking symmetry operations, specifically those pro…
