Preisschock bei Microsoft 365 mit Copilot: Australische Behörde reicht Klage ein
Nachdem Microsoft die Preise für das Office-Abo nach der Integration der Copilot-KI deutlich angehoben und eine Alternative versteckt hat, gibt es eine Klage.

Im Job nutze ich Microsoft Copilot täglich – und sehe Vorteile. Doch der Preis ist für europäische Unternehmen hoch: Datenhoheit, CLOUD Act, Abhängigkeit. Europa braucht dringend Alternativen, die funktionieren UND souverän sind. Mistral AI zeigt erste Ansätze. #KI #Office

Der Copilot-Dilemma: Ist der Zug an den Arbeitsplätzen bereits abgefahren?

Splitting Alternating Algorithms for Sparse Solutions of Linear Systems with Concatenated Orthogonal Matrices
A class of splitting alternating algorithms is proposed for finding the sparse solution of linear systems with concatenated orthogonal matrices. Depending on the number of matrices concatenated, the proposed algorithms are classified into the two-block splitting alternating algorithm (TSAA) and the multi-block splitting alternating algorithm (MSAA). These algorithms aim to decompose a large-scale linear system into two or more coupled subsystems, each significantly smaller than the original sys…

Preisschock Š la Microsoft: Mit der Copilot-KI steigen Office-365-Abos in Australien um bis zu 45%. Doch die günstigere Classic-Version bleibt dezent im Schatten des Kündigungsbuttons versteckt. Die ACCC klagt – zurecht. Transparenz sieht anders aus, sagt Martin Holland. #Microsoft365 #Copilot …

Exponential Suppression of the Unruh Effect and Geometric Enhancement in a Fermionic Cavity QED Setup
The Unruh effect -- the prediction that an accelerated observer perceives the vacuum as a thermal bath -- remains one of the most profound yet experimentally unverified consequences of quantum field theory. This work analyzes the decay of an excited state within a uniformly accelerated cavity to explain the historical null results and identify an alternative measurable signature. We model a massless Dirac field confined to a uniformly accelerated cavity, coupled to an external massive Dirac fie…

Closed-loop control of sloshing fuel in a spinning spacecraft
New-generation space missions require satellites to carry substantial amounts of liquid propellant, making it essential to analyse the coupled control-structure-propellant dynamics in detail. While Computational Fluid Dynamics (CFD) offers high-fidelity predictions, its computational cost limits its use in iterative design. Equivalent Mechanical Models (EMMs) provide a faster alternative, though their predictive performance, especially in closed-loop scenarios, remains largely unexplored. This …

Effect of nearby Metals on Electro-Quasistatic Human Body Communication
In recent decades Human Body Communication has emerged as a promising alternative to traditional radio wave communication, utilizing the body's conductive properties for low-power connectivity among wearables. This method harnesses the human body as an energy-efficient channel for data transmission within the electro-quasistatic frequency range, enabling advancements in human-machine interaction. While prior work has noted the role of parasitic return paths in such capacitively coupled systems,…

Analysis of divergent dynamics of exactly factorized electron-nuclear wavefunctions
The Exact Factorization (XF) of molecular wavefunctions can be viewed as an 'electronic wavepacket' framework for quantum dynamics. It is an appealing alternative to the conventional non-adiabatic dynamics, unfolding in the space of coupled electronic eigenstates. However, implementation of the non-linear XF equations for general systems presents a formidable challenge: the XF counterparts to the non-adiabatic coupling involve division by the nuclear probability density, which leads to severe n…
