Communications lost with
Gaza-bound aid ship Madleen
after Israeli navy tells it to change course
Freedom Flotilla Coalition says ship’s communications were jammed after Israeli defence minister threatened to ‘take all necessary measures’ to prevent the humanitarian ship from reaching Gaza

Yesterday, I watched "The Match" (승부), a movie that is now available on streaming platforms after it ran in cinemas in March. It tells the story of two Korean Go players who were both considered best in the world at some point: Cho Hun-hyun and Lee Chang-ho, a master and a student who later overtook the master. Side note: Lee Chang-ho was later followed by Lee Sedol as the world's best player who was then followed by AlphaGo. 1/2

Sentiment Analysis in Learning Management Systems Understanding Student Feedback at Scale
During the wake of the Covid-19 pandemic, the educational paradigm has experienced a major change from in person learning traditional to online platforms. The change of learning convention has impacted the teacher-student especially in non-verbal communication. The absent of non-verbal communication has led to a reliance on verbal feedback which diminished the efficacy of the educational experience. This paper explores the integration of sentiment analysis into learning management systems (LMS)…

Error Exponents for Quantum Packing Problems via An Operator Layer Cake Theorem
In this work, we prove a one-shot random coding bound for classical-quantum channel coding, a problem conjectured by Burnashev and Holevo in 1998. By choosing the optimal input distribution, we recover the optimal error exponent (i.e., the reliability function) of classical-quantum channels for rates above the critical rate. Our result extends to various quantum packing-type problems, including classical communication over any fully quantum channel with or without entanglement-assistance, const…

LIFT: Automating Symbolic Execution Optimization with Large Language Models for AI Networks
Dynamic Symbolic Execution (DSE) is a key technique in program analysis, widely used in software testing, vulnerability discovery, and formal verification. In distributed AI systems, DSE plays a crucial role in identifying hard-to-detect bugs, especially those arising from complex network communication patterns. However, traditional approaches to symbolic execution are often hindered by scalability issues and inefficiencies, particularly in large-scale systems. This paper introduces LIFT (Large…

Positive Geometry of Polytopes and Polypols
These are lecture notes supporting a minicourse taught at the Summer School in Total Positivity and Quantum Field Theory at CMSA Harvard in June 2025. We give an introduction to positive geometries and their canonical forms. We present the original definition by Arkani-Hamed, Bai and Lam, and a more recent definition suggested by work of Brown and Dupont. We compute canonical forms of convex polytopes and of quasi-regular polypols, which are nonlinear generalizations of polygons in the plane. T…

On-Demand Multimedia Delivery in 6G: An Optimal-Cost Steiner Tree Approach
The exponential growth of multimedia data traffic in 6G networks poses unprecedented challenges for immersive communication, where ultra-high-definition, multi-quality streaming must be delivered on demand while minimizing network operational costs. Traditional routing approaches, such as shortest-path algorithms, fail to optimize flow multiplexing across multiple destinations, while conventional Steiner tree methods cannot accommodate heterogeneous quality-of-service (QoS) requirements-a criti…

AI-based Environment-Aware XL-MIMO Channel Estimation with Location-Specific Prior Knowledge Enabled by CKM
Accurate and efficient acquisition of wireless channel state information (CSI) is crucial to enhance the communication performance of wireless systems. However, with the continuous densification of wireless links, increased channel dimensions, and the use of higher-frequency bands, channel estimation in the sixth generation (6G) and beyond wireless networks faces new challenges, such as insufficient orthogonal pilot sequences, inadequate signal-to-noise ratio (SNR) for channel training, and mor…

Climate change skepticism of European farmers and implications for effective policy actions - Communications Earth & Environment
The majority of farmers in European Union countries are more skeptical about climate change impact and attribution than the general population, and more so in more innovative and higher-income countries, according to an analysis of European-level surveys.
