Investigating Energy-Dependent Anisotropy in Cosmic Rays with IceTop Surface Array
This study presents preliminary results from the analysis of cosmic-ray anisotropy using air showers detected by the IceTop surface array between 2011 and 2022. With improved statistical precision and updated Monte Carlo simulation events compared to previous IceTop reports, we investigate anisotropy patterns across four energy ranges spanning from 300 TeV to 6.9 PeV. This work extends the measurement of cosmic-ray anisotropy in the southern hemisphere to higher energies than previously achieve…

Chambers and walls in spaces of real algebraic curves of small degrees
This paper reviews known results on the rigid isotopy classification of plane curves of degree $m\leq6$ and curves of small degrees on quadrics. The paper's study completes the rigid isotopy classification of nonsingular real algebraic curves of bidegree (4,3) on a hyperboloid, begun by the author in earlier works. There are given previously missing proofs of the uniqueness of the connected components for 16 classes of real algebraic curves of bidegree (4,3) having a single node or a cusp. The …

13CFLUX - Third-generation high-performance engine for isotopically (non)stationary 13C metabolic flux analysis
13C-based metabolic flux analysis (13C-MFA) is a cornerstone of quantitative systems biology, yet its increasing data complexity and methodological diversity place high demands on simulation software. We introduce 13CFLUX(v3), a third-generation simulation platform that combines a high-performance C++ engine with a convenient Python interface. The software delivers substantial performance gains across isotopically stationary and nonstationary analysis workflows, while remaining flexible to acco…

Triple-Tone Microwave Control for Sensitivity Optimization in Compact Ensemble Nitrogen-Vacancy Magnetometers
Ensembles of nitrogen-vacancy (NV) centers in diamond are a well-established platform for quantum magnetometry under ambient conditions. One challenge arises from the hyperfine structure of the NV, which, for the common $^{14}$N isotope, results in a threefold reduction of contrast and thus sensitivity. By addressing each of the NV hyperfine transitions individually, triple-tone microwave (MW) control can mitigate this sensitivity loss. Here, we experimentally and theoretically investigate the …

Fun Fact: ~35ya my sister and I were simultaneously users of what I understood to be the only 2 Isotope Ratio Mass Spectrometers in the world, the instrument used for measuring stable isotope ratios. She was a PhD student at Columbia doing paleoclimate work and I was at WashU studying the effect of rHGH on mid-term nitrogen balance and correlation to long-term growth in short kids without GH deficiency.

Decay study of the most neutron-deficient Zn isotopes with the Warsaw Optical TPC detector
Results of decay studies of nuclei in the vicinity of 54Zn, which is the most neutron-deficient isotope of zinc and undergoes ground-state two-proton radioactivity (2p), are presented. The measurements were performed with a gaseous time projection chamber with optical readout which allowed us to record tracks of protons emitted in the decays. A new method of data analysis was used to reconstruct energies and emission angles of low-energy protons that were stopped within the active volume of the…

I hadn't used the Bandcamp (fan) app until fairly recently, and it's wild the stuff up there - the feeds and messages are excellent and have really suggested me some great stuff.
Also, another Bandcamp Friday next week - October 3.

Is it Bandcamp Friday?
