NOAA hurricane hunters flying aboard a P-3 Orion aircraft ("Kermit") are monitoring Hurricane Melissa as most aircraft steer clear. The storm poses a catastrophic threat to Jamaica and Haiti.
The crew are among the many federal workers working without pay during the US government shutdown.

I'm feeling patriotic today... so it's Kraft Dinner for lunch. Pro tip - less milk and more butter.

Early on my way to another week of work.
I need music for this...
Yes, a Doctor singing 500 Miles, that will do it!

The mass of the Milky Way from outer halo stars measured by DESI DR1
As a benchmark for galaxy evolution and dark matter studies, the total mass of the Milky Way is a parameter of cosmological significance, and its value at large radii from the Galactic center remains highly uncertain. Following a hierarchical Bayesian inference approach, we measure the cumulative mass of the Milky Way using full 6D phase-space information of stars from the first data release of the Dark Energy Spectroscopic Instrument (DESI). We employ 330 blue horizontal-branch stars (BHBs) an…

Experimental Insights from OpenAirInterface 5G positioning Testbeds: Challenges and solutions
5G New Radio (NR) is a key enabler of accurate positioning in smart cities and smart factories. This paper presents the experimental results from three 5G positioning testbeds running open-source OpenAirInterface (OAI) gNB and Core Network (CN), using Uplink Time Difference of Arrival (UL-TDoA) with the newly integrated Location Management Function (LMF). The testbeds are deployed across both indoor factories and outdoor scenarios with O-RAN Radio Units (RUs), following a 3GPP-compliant system …

Prototyping of 6.2-mm-Pitch Fiber Positioner Modules for Stage-V Telescope Instrumentation
Small-pitch populated focal planes are a critical enabling technology for the next generation of highly multiplexed astronomical instruments. This work reports on ongoing prototyping activities for 6.2 mm-pitch alpha-beta (theta-phi) fiber positioner modules. Following a concise review of the underlying concept, the performance of trillium-based and independently actuated robotic designs is compared. Key operational parameters including XY positioning repeatability, non-linearity, backlash, and…

Science Lab: The Journey of 1,000 Defensive Miles https://www.dallascowboys.com/news/science-lab-the-journey-of-1-000-defensive-miles

Just reported that I found a couple of dead Salamander at beginning of August in the #Karwendel . 😞
Luckily I was following the Blog of karwendel.org. Otherwise I wouldn't have known that reports about such incidents should be reported:

Two-dimensional Yang-Mills theory via integrable probability
In this paper, we review the construction and large $N$ study of the continuous two-dimensional Yang-Mills theory with gauge group $\mathrm{U}(N)$ through probability, combinatorics and representation theory. In a first part, we define the continuous Yang-Mills measure using Markovian holonomy fields, following a construction by L{é}vy, then we show in a second part how to derive Migdal's character expansion of the partition function for any compact structure group from this setting. We contin…
