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 …

From Birdwatch to Community Notes, from Twitter to X: four years of community-based content moderation
Community Notes (formerly known as Birdwatch) is the first large-scale crowdsourced content moderation initiative that was launched by X (formerly known as Twitter) in January 2021. As the Community Notes model gains momentum across other social media platforms, there is a growing need to assess its underlying dynamics and effectiveness. This Resource paper provides (a) a systematic review of the literature on Community Notes, and (b) a major curated dataset and accompanying source code to supp…

"A 2021 report from Chainalysis revealed that in 2019 about 2.1% of all crypto transactions accounted went into criminal activity, or roughly $21.4 billion in transaction volumes. Meanwhile, the UN estimates that between 2% and 5% of global GDP (that is between $1.6 and $4 trillion in fiat currency) goes into illicit financing/money laundering every year. To paint a clearer picture, criminal activity using fiat currencies is 160 times more than its crypto counterpart."

Asymptotic behavior of mass-critical Schrödinger equation in $ \mathbb{R}$
In this paper, we study the long-time behavior for the mass-critical nonlinear Schrödinger equation on the line \[ i\partial_t u + \partial_x^2 u = |u|^4 u, u(0, x) = u_0 \in L_x^2(\Bbb R). \] The global well-posedness and scattering for this equation was solved in Dodson [Amer. J. Math. (2016)]. Inspired by the pioneering work of Killip-Visan-Zhang [Amer. J. Math. (2021)], we show that solution can be approximated by a finite-dimensional Hamiltonian system. This system is th…

RLZ-r and LZ-End-r: Enhancing Move-r
In pattern matching on strings, a locate query asks for an enumeration of all the occurrences of a given pattern in a given text. The r-index [Gagie et al., 2018] is a recently presented compressed self index that stores the text and auxiliary information in compressed space. With some modifications, locate queries can be answered in optimal time [Nishimoto & Tabei, 2021], which has recently been proven relevant in practice in the form of Move-r [Bertram et al., 2024].

Does $K$-fold CV based penalty perform variable selection or does it lead to $n^{1/2}$-consistency in Lasso?
Mayukh Choudhury, Debraj Das

Does $K$-fold CV based penalty perform variable selection or does it lead to $n^{1/2}$-consistency in Lasso?
Least absolute shrinkage and selection operator or Lasso, introduced by Tibshirani (1996), is one of the widely used regularization methods in regression. It is observed that the properties of Lasso vary wildly depending on the choice of the penalty parameter. The recent results of Lahiri (2021) suggest that, depending on the nature of the penalty parameter, Lasso can either be variable selection consistent or be $n^{1/2}-$consistent. However, practitioners generally implement Lasso by choosing…

Carney has announced LNG Canada will be expanded to its full potential. It will produce as much GHG emissions as 75% of the entirety of the province of British Columbia does right now. Yes, that's right. BC produced 61 million tons of GHGs in 2021, LNG Canada will produce 46 million tons at full power.
I am glad communities and health professionals are demanding a full inventory of the health impacts of this infrastructure. I hope that will also include the directly attributed heating from this plant to the increase in likelihood for wildfires, heat waves, and all the rest with all those health impacts across BC and the globe.
This is a gigantic project. Canada is a gigantic Climate Problem.

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…
