Diplomaten: Erneute Blockade der EU-Sanktionen gegen Russland
In der Europäischen Union sind offenbar erneut neue Sanktionen gegen Russland am Widerstand der Slowakei gescheitert. Das osteuropäische Land blockierte das 18. Russland-Sanktionspaket, sagten vier EU-Diplomaten der Nachrichtenagentur Reuters. Bereits am Dienstag hatte das osteuropäische Land verhindert, dass Russland wegen des Angriffs a…

EU-Sanktionen gegen Russland: Viel Einigkeit, aber keine Einigung
Beim Treffen der EU-Außenminister sollte das 18. Sanktionspaket gegen Russland beschlossen werden. Doch die Slowakei stellt sich quer. Auch die Finanzierung der "Patriot"-Systeme für die Ukraine ist offen.

Instruction Tuning and CoT Prompting for Contextual Medical QA with LLMs
Large language models (LLMs) have shown great potential in medical question answering (MedQA), yet adapting them to biomedical reasoning remains challenging due to domain-specific complexity and limited supervision. In this work, we study how prompt design and lightweight fine-tuning affect the performance of open-source LLMs on PubMedQA, a benchmark for multiple-choice biomedical questions. We focus on two widely used prompting strategies - standard instruction prompts and Chain-of-Thought (Co…

LLM-Driven Personalized Answer Generation and Evaluation
Online learning has experienced rapid growth due to its flexibility and accessibility. Personalization, adapted to the needs of individual learners, is crucial for enhancing the learning experience, particularly in online settings. A key aspect of personalization is providing learners with answers customized to their specific questions. This paper therefore explores the potential of Large Language Models (LLMs) to generate personalized answers to learners' questions, thereby enhancing engagemen…

Quorum sensing of light-activated colloids in nematic liquid crystals
Motile living organisms routinely probe their surroundings to adapt in ever-evolving environments. Although synthetic microswimmers offer surrogates for self-propelled living entities, they often lack the complex feedback mechanisms that enable organisms to adapt. In this work, we present an experimental platform in which light-activated colloids dispersed in a nematic liquid crystal can (i) switch from directed to active Brownian motion depending on the nematic anchoring and (ii) mechanically …

Crystal field tuned spin-flip luminescence in NiPS3
Layered magnetic materials potentially hold the key to future applications based on optical control and manipulation of magnetism. NiPS3, a prototype member of this family, is antiferromagnetic below 155 K and exhibits sharp photoluminescence associated to a transition between a triplet ground state and a singlet excited state. The nature of the luminescent transition is a matter of current debate and so is an eventual fundamental link of this excitation to magnetism. Here we provide answers th…

An Adaptive Order Caputo Fractional Gradient Descent Method for Multi-objective Optimization Problems
This article introduces the multi-objective adaptive order Caputo fractional gradient descent (MOAOCFGD) algorithm for solving unconstrained multi-objective problems. The proposed method performs equally well for both smooth and non-smooth multi-objective optimization problems. Moreover, the proposed method does not require any a priori chosen parameters or ordering information of the objective functions. At every iteration of the proposed method, a subproblem is solved to identify a suitable d…

Trump's Own Supporters Are Burning MAGA Hats & 'Epstein List' Is The Reason Why
U.S. President Donald Trump comes under fire amid Epstein case backlash. MAGA loyalists call for burning iconic 'Make America Great Again' caps. Trump's own support base turns against him as anger over 'Epstein Files' grows. Department of Justice (DOJ) has claimed Epstein did not maintain a 'client list'. This was despite promises from Attorney General Pam Bondi about 'a list on my table'. Bondi raised expectations of conservative influencers and conspiracy theorists. But then came DOJ's findin…
