Nick Offerman slams 'Parks and Rec' fan insinuating Ron Swanson is homophobic
Nick Offerman is standing up for queer 'Parks and Rec' fans after a user shared a manipulated image of his character, Ron Swanson, to spread homophobic hate: 'You dumb f---.

teaching a transformer net to approximate ray-tracing
input is a sequence of triangle data (limited to 4k triangles), and a sequence of 8x8 radiance pixels representing the camera (limited to 512x512 resolution)
output is a sequence of 8x8 pixels of the rendered scene. training was ~10 days. generation is ~100ms (NVIDIA A100)
the results are pretty good. scaling will be a challenge (since transformers are quadratic in sequence length)

SSIMBaD: Sigma Scaling with SSIM-Guided Balanced Diffusion for AnimeFace Colorization
We propose a novel diffusion-based framework for automatic colorization of Anime-style facial sketches. Our method preserves the structural fidelity of the input sketch while effectively transferring stylistic attributes from a reference image. Unlike traditional approaches that rely on predefined noise schedules - which often compromise perceptual consistency -- our framework builds on continuous-time diffusion models and introduces SSIMBaD (Sigma Scaling with SSIM-Guided Balanced Diffusion). …

Selenskyj definiert Schwerpunkte der Verhandlungen
Der ukrainische Präsident Wolodymyr Selenskyj hat die Verhandlungsbereitschaft seines Landes unterstrichen. "Wir sind bereit, die nötigen Schritte für den Frieden zu unternehmen", sagte er während eines Besuchs in Litauen. Als "Ausgangspunkt" für eine Einigung nannte Selenskyj eine Waffenruhe sowie "humanitäre Maßnahmen", die Befreiung von Kriegsgef…

Our meetup was well-attended with two interesting talks:
📋 Sarah Julia Kriesch presented "Docker vs Podman" - a beginner-friendly introduction to container basics and key differences between these tools.
🔧 Philip Laine showcased "Spegel", an OCI Registry Mirror that leverages torrent technology for efficient container image distribution - saving traffic costs and safeguarding against registry outages.

Effect of chromatic dispersion on image size and lattice plane curvature measurements with Rocking Curve Imaging
ADP crystals of large dimensions (80x80x20 mm3), to be used as a X-ray beam expanders in the BEaTriX facility at INAF-OABrera, have been characterised at BM05 beamline at ESRF synchrotron with the main purpose to determine lattice plane curvature with a unprecedent accuracy, as the BEaTriX setup requires a radius of curvature larger than 22 km. In this beamline, the monochromator is made by 2 Si(111) parallel crystals in the non-dispersive configuration. Due to the difference in the Bragg angle…

A Polarimetry-based Field-deployable Non-interruptive Mirror Soiling Detection Method
The soiling level of heliostat mirrors in Concentrated Solar Power (CSP) fields is one of the key factors that significantly influences optical efficiency. State-of-the-art methods of monitoring heliostats soiling levels still face various challenges, including slow speed, labor-intensive operations, resolution and accuracy constraints or interruptions to solar field operations. We present a rapid, cost-effective, and non-intrusive method for mirror soiling detection based on polarimetric imagi…

How important is the dielectric constant in water modeling? Evaluation of the performance of the TIP4P/$\varepsilon$ force field and its compatibility with the Joung-Cheetham NaCl model
Efficient large scale computer simulations of complex aqueous solutions require the use of accurate but simple empirical force fields for water. However, the growing complexity of these systems is evidencing the difficulties to describe solution properties without due account of polarization. Conflicting strategies to remedy this problem are parametrizing water force fields to the dielectric constant or charge scaling of the solvated ions. In this work we compare results from TIP4P/$\varepsil…

A highly sensitive SF$_6$-based leak test system for JUNO 3-inch PMT underwater electronics boxes
A total of 25600 3-inch photomultiplier tubes (PMTs), along with their corresponding frontend electronics, have been installed at the Jiangmen Underground Neutrino Observatory (JUNO). These electronics are housed in 200 stainless steel boxes that operate underwater. To verify the sealing integrity of the underwater boxes following integration, we developed an SF$_6$-based leak test system, opting against the typical helium-based system due to helium's ability to penetrate the PMT glass. After a…
