A direct approach to tree-guided feature aggregation for high-dimensional regression
In high-dimensional linear models, sparsity is often exploited to reduce variability and achieve parsimony. Equi-sparsity, where one assumes that predictors can be aggregated into groups sharing the same effects, is an alternative parsimonious structure that can be more suitable in certain applications. Previous work has clearly demonstrated the benefits of exploiting equi-sparsity in the presence of ``rare features'' (Yan and Bien 2021). In this work, we propose a new tree-guided regularizatio…

Slomads Rising: Stay Length Shifts in Digital Nomad Travel, United States 2019-2024
Using every U.S. Airbnb reservation created from 1 January 2019 through 31 December 2024, weighted by nights booked, we document a lasting shift toward longer stays after the COVID 19 shock. Mean nights per booking rose from 3.7 before the pandemic to a stable 4.1 to 4.4 after 2021; the median increased from two to three nights and the weighted standard deviation nearly doubled to seven nights, indicating a heavier tail. Negative binomial regression shows that, relative to the restriction perio…

Polarisation as a probe of neutrino emission from blazars
The source of extragalactic neutrinos in the TeV-PeV range is a matter of very active research, with blazar jets having been postulated to be the origin of at least some of the detections. The blazar PKS 0735+178 is a prominent example; during its multi-band flare in late 2021 a neutrino event was reported by four observatories, with its origin consistent with the direction of that source. While no new jet component was observed to be ejected during that narrow time-frame, our analysis shows th…

The noisy voter model with general initial conditions
We study the noisy voter model with $q\geq 2$ states and noise probability $θ$ on arbitrary bounded-degree $n$-vertex graphs $G$ with subexponential growth of balls (e.g., finite subsets of $\mathbb{Z}^d$). Cox, Peres and Steif (2016) showed for the binary case $q=2$ (and a wider class of chains) that, when starting from a worst-case initial state, this Markov chain has total variation cutoff at $t_n=\frac1{2θ}\log n$. The second author and Sly (2021) analyzed faster initial conditions for Gl…

We present VLT/MUSE observations of comet 67P/Churyumov-Gerasimenko during its 2021 perihelion passage, from which we generated simultaneous maps of dust, [OI], C$_2$, NH$_2$, and CN comae across 12 pre- and post-perihelion epochs. These maps reveal the evolutionary and compositional trends of 67P's coma and further enrich the context and findings of ESA's Rosetta mission. Dust and gas species displayed distinct structures, where NH$_2$ and CN signals were uniquely associated with known dust fa…

The $3$-sparsity of $X^n-1$ over finite fields

The $3$-sparsity of $X^n-1$ over finite fields
Let $q$ be a prime power and $\mathbb{F}_q$ the finite field with $q$ elements. For a positive integer $n$, the binomial $f_n(X):= X^n-1\in\mathbb{F}_q[X]$ is called $3$-sparse over $\mathbb{F}_q$ if each irreducible factor of $f_n(X)$ over $\mathbb{F}_q$ is either a binomial or a trinomial. In 2021, Oliveira and Reis characterized all positive integers $n$ for which $f_n(X)$ is $3$-sparse over $\mathbb{F}_q$ when $q = 2$ and $q = 4$, and posed the open problem of whether, for any given $q$, th…

From 66 to 4: Why Y Combinator backed fewer Indian startups in 2024
Y Combinator's selection of Indian startups has decreased significantly. This decline is attributed to factors like YC's US incorporation requirement and the rise of domestic IPOs. Indian startups are shifting focus to local funding options. They find domestic markets favorable for listing. YC is also prioritizing AI-focused startups. This shift impacts Indian participation. Domestic capital is growing with regulatory support.

Efficient Polynomial Identity Testing Over Nonassociative Algebras
We design the first efficient polynomial identity testing algorithms over the nonassociative polynomial algebra. In particular, multiplication among the formal variables is commutative but it is not associative. This complements the strong lower bound results obtained over this algebra by Hrubeš, Yehudayoff, and Wigderson (2010) and Fijalkow, Lagarde, Ohlmann, and Serre (2021) from the identity testing perspective. Our main results are the following: (1) We construct nonassociative algebras …

The angular resolution achieved for these observations ranged from 0.09-0.24 arcseconds, corresponding to ~420-1100 km at Callisto. Global surface properties were derived from the observations using a thermophysical model (de Kleer et al. 2021) constrained by spacecraft data. We find that …

Two detector modules with lithium aluminate targets were operated in the CRESST underground setup between February and June 2021.

The data are available online. In this document, we describe how the data set should be used to reproduce our dark matter results.
