Moreover, compact difference of a weighted composition operator and a unweighted composition operator on Hardy space is also stu…

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…

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…

This work questions this authoritative view, providing evidence of outperformance of smaller funds relative to t…

A three-step approach to reliably estimate magnetic field strengths in star-forming regions
The magnetic field is known to play a crucial role in star formation. Dust polarization is an effective tool for probing the morphology of the field, yet it does not directly trace its strength. Several methods have been developed, combining polarization and spectroscopic data, to estimate the strength of the magnetic field, including the DCF method, which relates these quantities to the magnetic-field strength under the assumption of Alfvénic turbulence. Skalidis & Tassis (2021) (ST), relaxed…

Invariants of twisted current algebras and related Poisson-commutative subalgebras
Let q be a finite-dimensional Lie algebra and $θ$ an automorphism of q of order m. We extend $θ$ to an automorphism of the loop algebra of q and consider the fixed-point subalgebra $q[t,t^{-1}]^θ$. Using a splitting of $q[t,t^{-1}]^θ$, we construct $θ$-twisted Poisson-commutative versions of the Feigin--Frenkel centre and the universal Gaudin subalgebra introduced by Ilin and Rybnikov in 2021.

We consider an M/M/1 feedback queue in which service attempts may fail, requiring the customer to rejoin the queue. Arriving customers act strategically, deciding whether to join the queue based on a threshold strategy that depends on the number of customers present. Their decisions balance the expected service reward against the costs associated with waiting, while accounting for the behavior of others.

Probing the energy-dependent temporal nature of MAXI J1803-298 with AstroSat and NICER
We performed the spectral and temporal analysis of MAXI J1803-298 using AstroSat/LAXPC and NICER observations taken in May 2021 during the initial phase of the outburst. We found that the source traverses through the hard, intermediate, and soft spectral states during the outburst. The spectrum in all states can be described using soft emissions from the thermal disk and hard emissions from the coronal regions. The variation in the inner disk temperature and normalization of the disk indicates …

Expanding the Pierre Auger Observatory Open Data program
Since 2021, the Open Data Portal has provided access to the Pierre Auger Observatory's data for both the scientific community and the general public. The data release process has been in place since the Observatory's foundation. It continues to be strengthened as outlined in the approved policy and the Observatory's Data Management Plan. More than 80 000 cosmic-ray events above $10^{17}$ eV, detected with the surface and fluorescence detectors, have been released at various levels, from calibra…

Texas Democrats had been out of state for less than 48 hours when Gov. Greg Abbott moved to have their seats declared vacant.
The emergency legal filing represents an unprecedented escalation of Abbott’s effort to pass a new congressional map that adds additional GOP seats -- as demanded by Donald Trump.
It flies in the face of Texas’ own founding documents,
centuries of legal precedent
and a recent Supreme Court of Texas ruling, legal experts say.
Even Attorney G…

Abbott’s bid to expel the House Democratic leader goes to a court filled with his appointees
The Texas Supreme Court said in 2021 the Constitution allows members to thwart legislation by leaving the state. Abbott wants them to reconsider.

Mode stability for self-similar blowup of slightly supercritical NLS: II. high-energy spectrum
In continuation of the study of the companion work, we prove the high-energy mode stability for linearized operator around self-similar profiles in [Bahri-Martel-Raphaël, 2021] for slightly mass-supercritical NLS in $1 \le d \le 10$. This concludes the asymptotic stability of such self-similar blowup, and answers the question from [Bahri-Martel-Raphaël, 2021] and [Merle-Raphaël-Szeftel, 2010]. As a byproduct, we characterize the spectrum for linearized operator around mass-critical ground st…

Antiquantum $q$-series and mock theta functions

Antiquantum $q$-series and mock theta functions
Ramanujan's original definition of mock theta functions from 1920 involves their asymptotic behaviors at roots of unity on the boundary of the disk of convergence $|q|<1$. More recently this topic has been related by several authors, including the first author with Ono and Rhoades in 2013, to quantum modular forms, first defined in 2010 by Zagier. In 2021, Lovejoy defined and studied related quantum $q$-series identities, which do not hold as equalities between power series inside the…

How much are LLMs changing the language of academic papers after ChatGPT? A multi-database and full text analysis
This study investigates how Large Language Models (LLMs) are influencing the language of academic papers by tracking 12 LLM-associated terms across six major scholarly databases (Scopus, Web of Science, PubMed, PubMed Central (PMC), Dimensions, and OpenAlex) from 2015 to 2024. Using over 2.4 million PMC open-access publications (2021-July 2025), we also analysed full texts to assess changes in the frequency and co-occurrence of these terms before and after ChatGPT's initial public release.
