Korea seems to be a new epicenter for cyberattacks, with a bunch of luxury brands, a giant telco, and now a major insurance company hit with ransomware attacks. If it were an English-speaking company, it would all seem very Scattered Spider-esque.

Patterns in Growth and Distribution of Unbounded Prime Number Walks
In our previous work, we defined a prime walk (PW) on a square grid and presented several intriguing numerical results. Here, we demonstrate the main conjecture presented there, namely, that the area covered by the prime walk is unbounded. Taking this fact into account, we examine in further detail the properties of the PW and explore new questions that arise naturally in this analysis.

Forecasting Climate Policy Uncertainty: Evidence from the United States
Forecasting Climate Policy Uncertainty (CPU) is essential as policymakers strive to balance economic growth with environmental goals. High levels of CPU can slow down investments in green technologies, make regulatory planning more difficult, and increase public resistance to climate reforms, especially during times of economic stress. This study addresses the challenge of forecasting the US CPU index by building the Bayesian Structural Time Series (BSTS) model with a large set of covariates, i…

Coalitions on the Fly in Cooperative Games
In this work, we examine a sequential setting of a cooperative game in which players arrive dynamically to form coalitions and complete tasks either together or individually, depending on the value created. Upon arrival, a new player as a decision maker faces two options: forming a new coalition or joining an existing one. We assume that players are greedy, i.e., they aim to maximize their rewards based on the information available at their arrival. The objective is to design an online value di…

You won’t hear this on the news but Scotland and other countries have declared their economy will be based on wellbeing, not GDP.
And They’re not alone.
Countries worldwide are making the same shift.
But here’s the thing: people aren’t waiting for governments.
EThey’re building wellbeing economies themselves through cooperatives, people’s assemblies, and businesses that put purpose over profit.

Sources said journalists’ Microsoft accounts were compromised and could have granted the intruder access to work emails they sent and received. The reporters targeted include those on the national security and economic policy teams, including some who write about China.
No paywall.

Learned Off-Grid Imager for Low-Altitude Economy with Cooperative ISAC Network
The low-altitude economy is emerging as a key driver of future economic growth, necessitating effective flight activity surveillance using existing mobile cellular network sensing capabilities. However, traditional monostatic and localizationbased sensing methods face challenges in fusing sensing results and matching channel parameters. To address these challenges, we model low-altitude surveillance as a compressed sensing (CS)-based imaging problem by leveraging the cooperation of multiple bas…

New allocation rule based on graph structures and their application to economic phenomena
This study introduces the \emph{edge-based Shapley value}, a novel allocation rule within cooperative game theory, specifically tailored for networked systems, where value is generated through interactions represented by edges. Traditional allocation rules, such as the Shapley and Myerson values, evaluate player contributions based on node-level characteristics, or connected components. However, these approaches often fail to adequately capture the functional role of edges, which are crucial in…
