The repetition threshold for ternary rich words
In 2017, Vesti proposed the problem of determining the repetition threshold for infinite rich words, i.e., for infinite words in which all factors of length $n$ contain $n$ distinct nonempty palindromic factors. In 2020, Currie, Mol, and Rampersad proved a conjecture of Baranwal and Shallit that the repetition threshold for binary rich words is $2 + \sqrt{2}/2$. In this paper, we prove a structure theorem for $16/7$-power-free ternary rich words. Using the structure theorem, we deduce that the …

Measurement of the Positive Muon Anomalous Magnetic Moment to 127 ppb
A new measurement of the magnetic anomaly $a_μ$ of the positive muon is presented based on data taken from 2020 to 2023 by the Muon $g-2$ Experiment at Fermi National Accelerator Laboratory (FNAL). This dataset contains over 2.5 times the total statistics of our previous results. From the ratio of the precession frequencies for muons and protons in our storage ring magnetic field, together with precisely known ratios of fundamental constants, we determine $a_μ = 116\,592\,0710(162) \times 10^…

"The RDBMS field is so young, we can actually see it grow through the pages of computer magazines of the 1980s. BYTE Magazine had its first issue dedicated to databases in November 1981, and then another one in October 1984. Dr. Dobb’s Journal did not feature an article about databases until 1984 and did not have many more throughout the decade; actually most of them were authored by Gene Head, and talk about dBASE."

We have often highlighted in the pages of this magazine the seemingly never-ending sequence of fashion waves hitting the software industry. We have discussed in 2020 the one impacting type systems, and more recently, another one concerning object-oriented programming. What is important in both cases is not the details of the technologies per se, but the social mechanisms at play in both situations. In this edition, we will encounter yet another example of such a clash, this time concerning rela…

Anticipated backward stochastic Volterra integral equations and their applications to nonzero-sum stochastic differential games
In [J. Wen, Y. Shi, Stat. Probab. Lett. 156 (2020) 108599] the authors first introduced a kind of anticipated backward stochastic Volterra integral equations (anticipated BSVIEs, for short). By virtue of the duality principle, it is found in this paper that the anticipated BSVIEs can be applied to the study of stochastic differential games. For this, in this paper we deeply investigate a more general class of anticipated BSVIEs whose generator includes both pointwise time-advanced functions and…

Harder, shorter, sharper, forward: A comparison of women's and men's elite football gameplay (2020-2025)
Elite football is believed to have evolved in recent years, but systematic evidence for the pace and form of that change is sparse. Drawing on event-level records for 13,067 matches in ten top-tier men's and women's leagues in England, Spain, Germany, Italy, and the United States (2020-2025), we quantify match dynamics with two views: conventional performance statistics and pitch-passing networks that track ball movement among a grid of pitch (field) regions. Between 2020 and 2025, average pass…

The Environmental Governance and Data Initiative (EDGI) regularly crawled US federal environmental websites between 2016 and 2020 to capture changes between two presidential administrations.

A Demonstration of Interstellar Navigation Using New Horizons
As NASA's New Horizons spacecraft exits the Solar System bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen from Earth. We demonstrated this by imaging the Proxima Centauri and Wolf 359 fields from Earth and New Horizons on 2020 April 23, when the spacecraft was 47.1 au distant. The observed parallaxes for Proxima Centauri and Wolf 359 are $32.4''$ and $15.7'',$ respectively. These measurements are not of research grade, b…

Spectral evolution of GX 17+2 using AstroSat and NICER observations
We study the spectral evolution of the Z-track source GX 17+2 using AstroSat and NICER observations taken between 2016 and 2020. The AstroSat observations cover the period when the source is in the normal branch (NB) and the flaring branch (FB), while for the NICER ones the variability can be associated with the FB branch. The source spectra at different regions of the branches are well described by accretion disk emission, blackbody surface emission and a thermal Comptonization component. In t…

It summarizes patterns, challenges, and lessons learned over 15 competitions organized by the group from 2015 to 2020. By describing these experiences, this report aims to help CodeLab to resume its events after the COVID-19 pandemic, and foster similar initiatives around the world.

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…

We study fault-tolerant consensus in a variant of the synchronous message passing model, where, in each round, every node can choose to be awake or asleep. This is known as the sleeping model (Chatterjee, Gmyr, Pandurangan PODC 2020) and defines the awake complexity (also called \emph{energy complexity}), which measures the maximum number of rounds that any node is awake throughout the execution. Only awake nodes can send and receive messages in a given round and all messages sent to sleeping n…

Symmetry and symmetry breaking in interpolation inequalities for two-dimensional spinors -- Preliminary results
On the two-dimensional Euclidean space, we study a spinorial analogue of the Caffarelli-Kohn-Nirenberg inequality involving weighted gradient norms. This (SCKN) inequality is equivalent to a spinorial Gagliardo-Nirenberg type interpolation inequality on a cylinder as well as to an interpolation inequality involving Aharonov-Bohm magnetic fields, which was analyzed in a paper of 2020. We examine the symmetry properties of optimal functions by linearizing the associated functional around radial m…

Julia Doubleday on the gamble that covid would be harmless to children
"It’s worth noting that at the time Kulldorff and the rest of the GBD crew were proclaiming COVID’s harmlessness to kids, they couldn’t possibly have had enough information to determine the veracity of their own claims. Viruses like the chickenpox, EBV, HIV, HPV, and HSV often present with mild initial infections but may cause major damage years later. We now know COVID can as well.
"For so-called experts to run with an assumption that an initially mild-presenting acute infection would be long-term harmless was just that; an assumption. They were willing to gamble the health of a generation of children on a guess in order to go “back to normal” because that’s what the oligarchy clamored for. Because it costs money to shut the world economy down. Because people who mattered were angry. Because children aren’t people who matter."
(GBD = Great Barrington Declaration, a bit of 2020 propaganda including the unfounded supposition that everyone who caught covid would be immune forever after)
Overall another excellent pointy article!
