Oh my, I just bought something from eBay for the first time in 15 years — wish me luck! My last experience (selling a laptop then) was super stressful, when the buyer ended up being a fraudster and it took months to get the money...
This time I ordered a dry heat press for my silver gelatin prints, very similar (but larger) to what I had in my first darkroom 35-40 years ago... My current approach pressing fiber prints under 20kg of books takes far too long and isn't scalable (in time …

Statement von Danger Dan und Igor Levit (leider nur auf Facebook und Instagram):
„Immer Ärger mit dem ZDF, dieses Mal haben sie uns ernsthaft rausgeschmissen.
Aber der Reihe nach...
Wir hatten gestern einen wunderschönen freien Tag in München, allerdings etwas unverhofft. Eigentlich waren wir eingeladen, um in der ZDF-TV-Sendung „Die Anstalt" ein antifaschistisches Lied zu spielen. Ganz kurz vor der Aufzeichnung hat allerdings die ZDF-Intendanz ihr Veto gegen unseren A…

A hacker group called Breach Boyz has been emailing local TV stations in Oklahoma with seemingly accurate PII, including the SSNs, of 30 inmates in the Rogers County jail, but authorities say there has been no breach.

Eight people were sentenced to prison June 23, 2026, in connection with the nonfatal shooting of an Alvarado police officer outside the Prairieland Detention Center July 4, 2025.
Authorities have called it the first-ever federal terrorism case associated with “antifa.”

Hello everyone.
I am taking a social media wellness break from posting my Weekend #Plankton Factoids for the boreal summer. I hope you have the opportunity to do something you enjoy over the season as well. Until then ❤️.

Un peu de Rêve de Dragon via Foundryvtt ce soir.
#Revededragon #foundryvtt #jdr

Cette image est une capture d'écran d'une table virtuelle de jeu de rôle (type Foundry VTT) représentant une carte fantastique.

    La carte principale (centre) : Elle montre une presqu'île ou zone côtière verdoyante bordée par l'océan (« LE TOURMENT »). On y distingue des chemins, des zones boisées, un symbole de dragon noir au centre, ainsi que plusieurs repères numérotés et étiquetés (« MERCENAIRES », « ARÈNES », « LA LEVÉE », « VIE BRÈVE »). Des jetons de personnages rond (tokens) sont pla…

Abstract: Positron range (PR) blurring is a fundamental resolution limitation in PET imaging with high-energy positron emitters such as 82Rb, causing contrast loss and spill-out effects across heterogeneous tissue interfaces. We propose PRC-TP, a positron range correction (PRC) framework with explicit texture preservation that decouples deterministic resolution recovery from stochastic texture restoration. A nnFormer-based neural network (NN) was trained on patient-derived Monte Carlo simulations to map PR-degraded 82Rb reconstructions to PR-free references using attenuation maps as anatomical context. However, this NN also significantly removed the noise in the images, which could impact some texture analysis methods or make the images look unrealistic. An auxiliary Noise2Noise model estimates that smoothing effect, enabling texture extraction and transfer to the PR-corrected prediction through Model-consistent Texture Re-Injection (MTRI). In simulated patients, PRC-TP preserved contrast recovery close to ground truth (GT) (98.96-99.04%) while restoring noise and CNR closer to the reference. The function-based MTRI formulation achieved near unity global texture amplitude agreement with GT (0.997 /- 0.011), reducing the input texture amplitude bias (0.951 /- 0.011). Radiomics analysis showed improved agreement with GT across texture-sensitive feature families. A clinical 82Rb evaluation showed trends consistent with simulations, including comparable contrast-ratio increase (10.18% vs. 10.99%) and restoration of texture suppressed by PRC. These results support PRC-TP as a practical framework for resolution recovery with acquisition-consistent texture preservation in PET imaging.
