Confirmed: another big jump in atmospheric CO2 concentration. The June average at Mauna Loa was 429.6 ppm, that's 2.7 ppm more than last year!

Auf den ersten Blick klingt es ganz logisch, daß reaktionäre Politik die Welt zurückbringt, aber deswegen kommen wir damit nicht zurück zu 300 ppm CO₂. So funktioniert Physik nicht.

Confirmed: the May average of atmospheric CO2 at Mauna Loa was 430.5 ppm, first time above 430 ppm in 15 million years, and a big jump from a year ago, again: 3.6 ppm!
Overall, we're still speeding in the wrong direction.

Permutation patterns in streams
Permutation patterns and pattern avoidance are central, well-studied concepts in combinatorics and computer science. Given two permutations $τ$ and $π$, the pattern matching problem (PPM) asks whether $τ$ contains $π$. This problem arises in various contexts in computer science and statistics and has been studied extensively in exact-, parameterized-, approximate-, property-testing- and other formulations. In this paper, we study pattern matching in a \emph{streaming setting}, when the in…

JWST COMPASS: A NIRSpec G395H Transmission Spectrum of the Super-Earth GJ 357 b
We present JWST NIRSpec/G395H transmission spectroscopy observations of GJ 357 b, a warm ($T_{\mathrm{eq}} \approx 525$ K) super-Earth ($1.2\ \mathrm{R_{\oplus}} $, $1.84\ \mathrm{M_{\oplus}} $) orbiting a nearby M3-type star, with a median precision of 18 ppm and 27 ppm in NRS1 and NRS2, respectively. These precisions are obtained by binning the spectrum into 53 spectroscopic channels with a resolution of 60 pixels (around 0.02 $μ$m) each. Our analysis of the transmission spectrum reveals no …

The @noaa.gov site is slow to publish the June average of atmospheric CO₂. In these times of Trump's war on climate science (building and staff already affected), this makes me worry about the end of the Keeling curve, the valuable record of 67 years. Daily measurements still coming in, though.

Another big jump in atmospheric CO₂ measured at Mauna Loa*: based on daily values, the June average was ~429.7 ppm, that's 2.8 ppm higher than last year!

Run 2/3 measurement of the muon anomalous magnetic moment by the Muon g-2 experiment at Fermilab
The Muon g-2 experiment at Fermilab seeks to measure the muon magnetic moment anomaly, $a_μ=(g-2)/2$, with a final target precision of 0.14 parts-per-million (ppm). The experiment's initial result, published in 2021 using Run 1 data from 2018, confirmed the previous measurement at Brookhaven National Laboratory with a comparable sensitivity of 0.46 ppm. In 2023, a new result based on Run 2 and Run 3 data, collected in 2019 and 2020, was released. These datasets contain four times the data from…

Fundamental Limits of Pulse Based UWB ISAC Systems: A Parameter Estimation Perspective
This paper investigates a bi-static integrated sensing and communication (ISAC) system for multi-target scenarios using impulse radio ultra-wideband (IR-UWB) signals, which offer fine temporal resolution, low power consumption, and strong resistance to multipath interference. Two typical modulation schemes, namely pulse position modulation (PPM) and binary phase shift keying (BPSK), are considered for communication over the delay and phase domains, respectively. Accordingly, we introduce a pilo…

Based on daily values, the May average of atmospheric CO₂ at Mauna Loa was ~430.5 ppm; that's 3.6 ppm higher than last year, a big jump again!

High-Precision Quantum Dynamics of He$_2$ b $^3Π_\mathrm{g}$-c $^3Σ_\mathrm{g}^+$ including Non-adiabatic, Relativistic and QED Corrections and Couplings
Relativistic, quantum electrodynamics, as well as non-adiabatic corrections and couplings, are computed for the b $^3Π_\mathrm{g}$ and c $^3Σ_\mathrm{g}^+$ electronic states of the helium dimer. The underlying Born-Oppenheimer potential energy curves are converged to 1 ppm ($1:10^6$) relative precision using a variational explicitly correlated Gaussian approach. % The quantum nuclear motion is computed over the b $^3Π_\mathrm{g}$-c $^3Σ_\mathrm{g}^+$ (and B $^1Π_\mathrm{g}$-C $^1Σ_\mathrm…

Rovibrational computations for the He$_2$ a $^3Σ_\mathrm{u}^+$ state including non-adiabatic, relativistic, and QED corrections
A potential energy curve (PEC) accurate to a fraction of 1 ppm ($1:10^6$) is computed for the $^3Σ_\mathrm{u}^+$ state of He$_2$ endowed with relativistic and QED corrections. The nuclear Schrödinger equation is solved on this PEC with diagonal Born-Oppenheimer and non-adiabatic mass corrections to obtain highly accurate rotational-vibrational levels. The computed rovibrational intervals and fine-structure splittings, spanning over several orders of magnitude in energy, are found to be in rem…
