Exoplanet Atmospheric Escape Observations with the Habitable Worlds Observatory
The Decadal Survey on Astronomy and Astrophysics 2020 highlights the importance of advancing research focused on discovering and characterizing habitable worlds. In line with this priority, our goal is to investigate how planetary systems evolve through atmospheric escape and to develop methods for identifying potentially Earth-like planets. By leveraging the ultraviolet (UV) capabilities of the Habitable Worlds Observatory (HWO), we can use transit spectroscopy to observe atmospheric escape in…

Comment on "A Note on Over-Smoothing for Graph Neural Networks"
We comment on Cai and Wang (2020, arXiv:2006.13318), who analyze over-smoothing in GNNs via Dirichlet energy. We show that under mild spectral conditions (including with Leaky-ReLU), the Dirichlet energy of node embeddings decreases exponentially with depth; we further extend the result to spectral polynomial filters and provide a short proof for the Leaky-ReLU case. Experiments on edge deletion and weight amplification illustrate when Dirichlet energy increases, hinting at practical ways to re…

What began as a silent infiltration into one of the world’s largest cryptocurrency mining pools has now been confirmed as
the biggest crypto theft in history.
The LuBian mining pool, once a dominant force in the Bitcoin network, quietly lost over 127,000 Bitcoins in 2020.
The breach was only uncovered in 2025 by Arkham Intelligence, revealing a staggering $14.5 billion worth of stolen assets that had remained untouched and undetected for half a decade

The limit of repetition thresholds of rich sequences
The repetition threshold of a class of sequences is the smallest number $r$ such that a sequence from the class contains no repetition with exponent $> r$. We focus on the class $\mathcal{C}_d$ of $d$-ary sequences rich in palindromes. In 2020, Currie, Mol, and Rampersad determined the repetition threshold for $\mathcal{C}_2$. In 2024, Currie, Mol and Peltomäki found the repetition threshold for $\mathcal{C}_3$ and conjectured that the repetition threshold for $\mathcal{C}_d$ tends to 2 with $…

A federal jury in Colorado has found MyPillow founder Mike Lindell defamed a former employee for a leading voting equipment company.

Non self-similar metabelian groups
We show some sufficient conditions for a finitely presented group $G = A \rtimes Q$, with $A$ and $Q$ abelian and the Krull dimension of $A$ equals to $2$ to be not self-similar. This is in contrast to the case of the Krull dimension of $A$ equals to $1$ considered by Kochloukova and Sidki in 2020.

The Journey of CodeLab: How University Hackathons Built a Community of Engaged Students
This paper presents the journey of CodeLab: a student-organized initiative from the University of São Paulo that has grown thanks to university hackathons. 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.

Invisible Labor, Visible Barriers: The Socioeconomic Realities of Women's Work in Pakistan
We provide a short note on the barriers shaping womens economic opportunities in Pakistan, where female labor force participation remains among the lowest in the world. Recent labor force surveys (2020-21) show a sharp rural-urban divide: rural womens participation is 28 percent compared to 69 percent for rural men, while urban womens participation is 10 percent compared to 66 percent for urban men. Unemployment is higher for women in both rural (7 percent) and urban (16 percent) areas than for…

On Rota--Baxter operators on finite simple groups of Lie type
Rota--Baxter operators on groups were introduced by L. Guo, H. Lang, Yu. Sheng in 2020. In 2023, V. Bardakov and the second author showed that all Rota--Baxter operators on simple sporadic groups are splitting, i.\,e. they correspond to exact factorizations of groups. In 2024, the authors of the current paper described all non-splitting Rota--Baxter operators on alternating groups. Now we describe Rota--Baxter operators on finite simple exceptional groups of Lie type and projective special li…

Quantum Radar and Research Assessment
Quantum Radar was studied in many Nations for about fifteen years with the production of some hundred publications. In the post 2020 literature, it is shown that, due to the exceedingly low transmitted power, Quantum Radar cannot produce neither significant results nor real world applications. Regrettably, most of the scientific community ignored this negative outcome: a fact worth of exam. A detailed study of such an assessment failure depicts the main shortcomings of the present situation, ca…

A new Lagrange multiplier approach for constructing structure preserving schemes, III. Bound preserving and energy dissipating
In the third part of this series, we continue to explore the idea of the Lagrange multiplier introduced in the first part [2020, Comput. Methods Appl. Mech. Engr., 391, 114585] and refined in the second part [2022, SIAM J. Numer. Anal., 60, 970-998] to further develop efficient and accurate numerical schemes that preserve the maximum bound principle (MBP) and energy dissipation for solving gradient flows. The proposed framework allows us to begin with any conventional scheme as a predictor step…

Longitudinal review of portfolios with minimum variance approach before during and after the pandemic
This study investigates the impact of the pandemic on the most traded stocks in the Colombian stock market for the date of January 17, 2024. Based on the daily data of the most traded companies in Colombia for said date and covering a period general from 2015 to 2023, in a summarized way our analysis reveals that in the period 2015-2019, the return reached 5.70%, with a relatively low risk of 18.45%. However, in the following period 2016 -2020, although the yield decreased to 5.40%, the risk ex…

Detection, attribution, and modeling of climate change: key open issues
The CMIP global climate models (GCMs) assess that nearly 100% of global surface warming observed between 1850-1900 and 2011-2020 is attributable to anthropogenic drivers like greenhouse gas emissions. These models also generate future climate projections based on shared socioeconomic pathways (SSPs), aiding in risk assessment and the development of costly Net-Zero climate mitigation strategies. Yet, the CMIP GCMs face significant scientific challenges in attributing and modeling climate change,…

Strong list-chromatic index of subcubic graphs is at most 10
A strong edge coloring of a graph $G$ is an assignment of colors to the edges of $G$ such that two distinct edges are colored differently if they are incident to a common edge or share an endpoint. The strong chromatic index of a graph $G$, denoted by $χ_{s}'(G)$, is the minimum number of colors needed for a strong edge coloring of $G$. The edge weight of a graph $G$ is defined to be $\max\limits_{uv\in E(G)}\{(d_G(u)+d_G(v))\}$. It was proved in Chen et al in 2020 that every graph with edge w…

This study proposes a novel portfolio optimization framework that integrates statistical social network analysis with time series forecasting and risk management. Using daily stock data from the S&P 500 (2020-2024), we construct dependency networks via Vector Autoregression (VAR) and Forecast Error Variance Decomposition (FEVD), transforming influence relationships into a cost-based network. Specifically, FEVD breaks down the VAR's forecast error variance to quantify how much each stock's shock…

To address the challenge of managing dynamic portfolios in such an environment, this paper presents a practical application of a multi-agent system designed to autonomously construct and evaluate crypto-asset allocations. Using data on daily frequencies of the ten most capitalized cryptocurrencies from 2020 to 2025, we compare two automated investment strategies. …
