Kommentar: Die Steam Machine für 1040 Euro ist einfach kein guter Deal
Die Steam Machine ist kompakt, schick und mit mindestens 1040 Euro zu teuer. Für jeden Einsatzzweck gibt es bessere Alternativen, meint Daniel Herbig.

OpenAI says its AI technology acted on its own in an ‘unprecedented’ hack of another company
AI startup Hugging Face said last week that it had detected an intrusion into its data processing systems
that it suspected was caused by an AI agent autonomously acting on its own.
“We suspected last week’s cyberattack might have come from a frontier lab,
given the sophistication of the agent,”

Cela est un test primordial pour la république, l'état et l'état de droit. La surveillance de masse et massacrer les manifestants est une chose. LŠ, le test c'est aussi, si la bureaucratie va gagner sur l'efficacité. C'est vraiment un défi pour l'état.

Abstract: A kV dual tube system has been disseminated as a commercial research platform for preclinical FLASH radiotherapy (RT). Because the tubes are arranged in a parallel opposed geometry, both output symmetry and time resolved tube synchronization are critical for achieving sufficiently high dose rates (DR) and reproducible study results. We quantified tube output asymmetry observed in depth dose measurements as well as tube synchronization and evaluated their impact on FLASH studies. The dual-tube system defines dose per pulse as the combined single pulse output from both tubes, with DR given by dose per pulse/pulse length. 3D dose distributions were reconstructed from film measurements to assess the impact of output discrepancies. Pulse synchronization between tubes was characterized using a scintillator with 1 ms resolution. We showed >20% discrepancies in output at nominally equal mA/ms settings. After we compensated such discrepancy by decreasing the current of the tube with higher output, the inter tube output difference was reduced to <1%, restoring symmetrical depth dose. We further simulated an in vivo intestinal irradiation in which naive tube settings resulted in >22% of the organ volume receiving >102% of the prescribed dose, compared with <7% when output compensation was applied. We identified a 10.2 /- 7.0ms synchronization jitter between tubes, which disproportionately impacts the DR at low dose-per-pulse settings, particularly relevant for fractionated studies. Corresponding quality assurance (QA) was designed to monitor tube synchronization over time. We quantified the dosimetric impact of asymmetric output and synchronization and demonstrated implications for preclinical studies. The proposed methodology and QA would mitigate and monitor these effects, ensuring study reproducibility.
