Bei der Beerdigung von Charlie Kirk waren mehr Gäste als bei der vereidigung von trump. Er lässt ihn jetzt ausgraben und nochmal töten. #Kadaversynode.

Wenn Donald #Trump den ermordeten #Hetzer Charlie #Kirk so hochjubelt und als Märtyrer der rechten Sache ausruft, erinnert mich das – obwohl es nicht wirklich vergleichbar ist - an das Attentat auf Reinhard Heydrich. Kirk h…

Non-invasive Reversible Software-based Configuration of a Clinically Used Linear Accelerator for Preclinical Electron FLASH Radiobiology
Configuring clinical linear accelerators (linacs) for ultra-high dose rate (UHDR) electron experiments typically requires invasive hardware manipulation and/or irreversible manufacturer modifications, limiting broader implementation. We present an independently developed UHDR electron configuration of a clinical TrueBeam linac that allows reversible switching between preclinical UHDR and conventional (CONV) modes using only non-invasive software settings. UHDR mode was achieved via service mode…

Engineering High-Order Harmonic Generation through Gas Confinement at Sub-Millimeter Lengths
Attosecond light sources based on high-order harmonic generation (HHG) constitute to date the only table-top solution for producing coherent broadband radiation covering the spectral range from the extreme ultraviolet to the soft X-rays. The so-called emission cutoff can be extended towards higher photon energies by increasing the driving wavelength at the expense of conversion efficiency. An alternative route is to overdrive the process by using higher laser intensities, with the challenging r…

Physics of the gluon mass gap
It has long been known that the gluon propagator in Landau-gauge QCD exhibits a mass gap; and its emergence has been ascribed to the action of the Schwinger mechanism in the gauge sector of QCD. In the present work, we relate this property to the physical mass gap of QCD by considering two observables associated with confinement and chiral symmetry breaking, namely the confinement-deconfinement transition temperature and the pion decay constant, respectively. It turns out that the first observa…

Search for spontaneous fission of plutonium and americium nuclides using gamma spectrometry
Spontaneous fission in americium and plutonium isotopes was investigated using high-resolution gamma spectrometry. This process was investigated through analysis of a certified PuO2 sample spectrum obtained from the IAEA database of reference spectra. Measurements were carried out with a HPGe detector, and detection efficiency calibration was performed by Monte Carlo simulations using GEANT4. There are no peaks observed that can be ascribed to beta decay of expected spontaneous-fission daughter…
