Tariff chaos is forcing America’s allies closer together,
-- and further from the United States.
As that happens, the European Union is trying to position itself at the center of a new global trade map.

Amid Tariff Chaos, U.S. Allies Try to Redraw the Trade Map
Facing growing chaos, the European Union and numerous other countries are seeking to forge a global trading nexus that is less vulnerable to American tariffs.

A closer look at the algebraic-operator correspondence between position and momentum space in Quantum Mechanics
In this work we take a closer look at the algebraic-operator correspondence between the momentum ($k$) space and the position ($x$) space which gives us the form of the momentum operator in position space and vice versa in Quantum Mechanics. Taking the definition of the Fourier Transform as the starting point, we present a two parameter generalisation of the form of the momentum operator in position space followed by a generalisation of the momentum eigenfunctions and a few other results. It is…

Inverted Classroom in der Einführungsveranstaltung Programmierung
Traditionally, the introductory programming course for computer science students at Nuremberg Tech had been implemented as a combination of lectures and exercise sessions. Due to high failure rates in the winter semester 2023/24, an experimental teaching concept based on the inverted classroom was implemented for one cohort in the winter semester 2024/25. Students had to prepare themselves through literature work and activating teaching and learning methods. The course was accompanied by a seri…

Methinks that Israel's attack on Iran is going to result in an effective closure of the Straint of Hormuz which will, in turn, cause a severe shortage of petroleum shipments to much of the world.
At a minimum, I would expect that the tsunami-sized impact of that will afflict prices of gasoline here in the US.

Mastery Learning Improves Performance on Complex Tasks on PCP Literacy Test
Developing literacy with unfamiliar data visualization techniques such as Parallel Coordinate Plots (PCPs) can be a significant challenge for students. We adopted the Revised Bloom's taxonomy to instruct students on Parallel Coordinate Plots (PCPs) using Mastery Learning in the classroom. To evaluate Mastery Learning's impact, we conducted an intervention in a Data Visualization course to teach students about PCPs using the Revised Bloom's taxonomy with and without Mastery Learning. Based on ou…

SimClass: A Classroom Speech Dataset Generated via Game Engine Simulation For Automatic Speech Recognition Research
The scarcity of large-scale classroom speech data has hindered the development of AI-driven speech models for education. Public classroom datasets remain limited, and the lack of a dedicated classroom noise corpus prevents the use of standard data augmentation techniques. In this paper, we introduce a scalable methodology for synthesizing classroom noise using game engines, a framework that extends to other domains. Using this methodology, we present SimClass, a dataset that includes both a s…

Towards Zero-Stall Matrix Multiplication on Energy-Efficient RISC-V Clusters for Machine Learning Acceleration
The growing computational demands of machine learning (ML) workloads have driven the design of ML accelerators aiming at an optimal tradeoff between efficiency and flexibility. A widely explored architecture for flexible ML accelerators is based on clusters of lightweight instruction processors sharing multi-banked L1 memory, augmented with specialized instruction extensions for key ML-related computations, such as matrix multiplication (matmul). However, instruction extensions should be couple…
