Explanation of the seasonal variation of cosmic multiple muon events observed with the NOvA Near Detector
The flux of cosmic ray muons at the Earth's surface exhibits seasonal variations due to changes in the temperature of the atmosphere affecting the production and decay of mesons in the upper atmosphere. Using data collected by the NOvA Near Detector during 2018--2022, we studied the seasonal pattern in the multiple-muon event rate. The data confirm an anticorrelation between the multiple-muon event rate and effective atmospheric temperature, consistent across all the years of data. Previous ana…

Treedepth and 2-treedepth in graphs with no long induced paths
Huynh, Joret, Micek, Seweryn, and Wollan (Combinatorica, 2022) introduced a graph parameter, later referred to as 2-treedepth and denoted $\mathrm{td}_2(\cdot)$. The parameter is the natural 2-connected version of treedepth. For every graph, 2-treedepth is at most the treedepth but can be much smaller: long paths have arbitrary treedepth but 2-treedepth equal to 2. We prove a converse, showing that every graph $G$ with no induced path on $t$ vertices has treedepth less than $2 \cdot t^{\mathrm{…

Extendability of $1$-decomposable complexes
A well-known conjecture of Simon (1994) states that any pure $d$-dimensional shellable complex on $n$ vertices can be extended to $Δ_{n-1}^{(d)}$, the $d$-skeleton of the $(n-1)$-dimensional simplex, by attaching one facet at a time while maintaining shellability. The notion of $k$-decomposability for simplicial complexes, which generalizes shellability, was introduced by Provan and Billera (1980). Coleman, Dochtermann, Geist, and Oh (2022) showed that any pure $d$-dimensional $0$-decomposab…

Climate change: across time and frequencies
We use continuous wavelet tools to characterize the dynamics of climate change across time and frequencies. This approach allows us to capture the changing patterns in the relationship between global mean temperature anomalies and climate forcings. Using historical data from 1850 to 2022, we find that greenhouse gases, and CO$_2$ in particular, play a significant role in driving the very low frequency trending behaviour in temperatures, even after controlling for the effects of natural forcings…

Projected branes as platforms for crystalline, superconducting, and higher-order topological phases
Projected branes are constituted by only a small subset of sites of a higher-dimensional crystal, otherwise placed on a hyperplane oriented at an irrational or a rational slope therein, for which the effective Hamiltonian is constructed by systematically integrating out the sites of the parent lattice that fall outside such branes [Commun. Phys. 5, 230 (2022)]. Specifically, when such a brane is constructed from a square lattice, it gives rise to an aperiodic Fibonacci quasi-crystal or its rati…

This ends up being a really interesting read about the challenges of a country to fight corruption while it tries to achieve everything it needs to do become part of the EU.
Moldova and Ukraine started the process together 2022. Imagine if they could actually achieve it together in 2028!

Search for the Higgs boson decay to a $Z$ boson and a photon in $pp$ collisions at $\sqrt{s}=13$ TeV and $13.6$ TeV with the ATLAS detector
A search for the Higgs boson decay to a $Z$ boson and a photon in the $\ell\ellγ$ ($\ell = e, μ$) final state is performed using $pp$ collisions at $\sqrt{s}=13.6$ TeV recorded with the ATLAS detector at the Large Hadron Collider during 2022-2024, corresponding to an integrated luminosity of 165 fb$^{-1}$. The signal yield, normalised to the Standard Model prediction, is measured to be $μ=0.9^{+0.7}_{-0.6}$, compared to an expected value of $μ=1.0\pm0.7$. This corresponds to an observed (ex…

On Generators of Bloch groups of CM fields
This article generalizes the result of Burns et al (2022), to find an algorithm to find some elements generating a full-rank subgroup of the torsion-free part of Bloch group of a certain CM number field, and compute the rank of it.

On saturation problems for matchings with regularity constraints
A graph $G$ is $F$-saturated if $G$ is $F$-free but for any edge $e$ in the complement of $G$ the graph $G + e$ contains $F$. Gerbner et al. (Discrete Math., 345 (2022), 112921) initiated the study of $rsat(n,F)$, the minimum number of edges in a regular $n$-vertex $F$-saturated graph, and they posed the problem of for which graphs $rsat(n, F )$ exists. Regarding this problem, we obtain the precise value of $rsat(n,(m+1)K_2)$ for all possible cases, where $(m+1)K_2$ denotes a matching of size $…

PDE-Based Bayesian Hierarchical Modeling for Event Spread, with Application to COVID-19 Infection
We extended the Wikle's Bayesian hierarchical model based on a diffusion-reaction equation [Wikle, 2003] to investigate the COVID-19 spatio-temporal spread events across the USA from Mar 2020 to Feb 2022. Our model incorporated an advection term to account for the intra-state spread trend. We applied a Markov chain Monte Carlo (MCMC) method to obtain samples from the posterior distribution of the parameters. We implemented the approach via the collection of the COVID-19 infections across the st…

Microwave Imaging Spectroscopy Diagnosis of the Slow-rise Precursor of a Major Solar Eruption
In this Letter, taking advantage of microwave data from the Expanded Owens Valley Solar Array and extreme-ultraviolet (EUV) data from the Atmospheric Imaging Assembly, we present the first microwave imaging spectroscopy diagnosis for the slow-rise precursor of a major coronal mass ejection (CME) on 2022 March 30. The EUV images reveal that the CME progenitor, appearing as a hot channel above the polarity inversion line, experiences a slow rise and heating before the eruption. The microwave emis…

Separable convex optimization over indegree polytopes
We study egalitarian (acyclic) orientations of undirected graphs under indegree-based objectives, such as minimizing the $φ$-sum of indegrees for a strictly convex function $φ$, decreasing minimization (dec-min), and increasing maximization (inc-max). In the non-acyclic setting of Frank and Murota (2022), a single orientation simultaneously optimizes these three objectives, however, restricting to acyclic orientations confines us to the corners of the indegree polytope, where these fairness o…

Got my water/utility bill for the spring/summer yesterday. (we get billed 3 times a year as part of our general city utilities bill including water, sewer and garbage/recycling fees).
Figured it would be a big water year this year so I've been wanting to see this. And of course, I have data going back to 2019ish.
Today's bill only goes to August 1st, so it doesn't include when we started to fill the #pondpool!
This was already a dry year in the spring and we were doing lots of watering in the front yard for the new ground cover in the modified driveway and the 3 new fruit trees.
Verdict:
2024: Apr 12 - Aug 7: 122, 200L
2025 Apr 14 - Aug 1 (7 less days!): 136,600L
It will be interesting to see if the August pond filling will add a big chunk onto our summer/fall consumption or if that is offset by both the brief August water restrictions, and the departure of both kids this fall to consume other people's water. ;=)
If you want an indication of how much water people use vs. yards: look at our August 2022 bill, which captures when we were on our cross-Canada roadtrip for 30 days in July/August of the 100 day period.

The spectral Turán problem: Characterizing spectral-consistent graphs
Let ${\rm EX}(n,H)$ and ${\rm SPEX}(n,H)$ denote the families of $n$-vertex $H$-free graphs with the maximum size and the maximum spectral radius, respectively. A graph $H$ is said to be spectral-consistent if ${\rm SPEX}(n,H)\subseteq {\rm EX}(n,H)$ for sufficiently large $n$. A fundamental problem in spectral extremal graph theory is to determine which graphs are spectral-consistent. Cioabă, Desai and Tait [European J. Combin. 99 (2022) 103420] proposed the following conjecture: Let $H$ be…
