This paper introduces physical differential fuzz testing as a holistic challenge-response framework that authenticates cyber-physical systems by comparing output signatures against a baseline to detect tampering in hardware, firmware, and software, demonstrating its effectiveness in verifying radiation measurement equipment for nuclear arms control.
This paper reports a 100-fold improvement in sensitivity for detecting new gravity-like forces at micrometer scales using optically levitated microspheres, establishing the first multi-component vector force measurements and setting stringent new upper limits on Yukawa-type interactions in the 5–10 μm range.
The TESSERACT Collaboration reports the first limits on light dark matter interactions using a low-threshold, two-channel athermal phonon detector operated above ground, achieving the best energy resolution for such devices and setting the most stringent constraints to date for dark matter masses between 44 and 87 MeV/.
Researchers successfully demonstrated the first observation of narrow-band 1.3 MeV radiation by channeling an 855 MeV electron beam through a boron-doped diamond superlattice acting as a crystalline micro-undulator, a breakthrough that paves the way for generating highly directional 14.5 MeV -ray beams with optimized doping profiles for future 3 GeV accelerators.
This paper establishes a rigorous quantum optical framework for analyzing diffraction-induced vacuum field injection in DECIGO's Fabry-Perot cavities, demonstrating that while such losses slightly increase radiation pressure noise, cavity detuning combined with homodyne detection and optical-spring locking can effectively mitigate these effects to enhance the detector's sensitivity to primordial gravitational waves.
This study presents the first experimental demonstration of Positronium Lifetime Imaging (PLI) using the Sc isotope and the plastic scintillator-based J-PET scanner on a NEMA-Image Quality phantom, addressing the prompt gamma limitations of previous isotopes like Ga to advance submolecular tissue characterization.
The KIPM Detector Consortium, a collaboration of university and national lab groups, aims to achieve sub-eV energy thresholds for light dark matter and low-energy neutrino searches by advancing Kinetic Inductance Phonon-Mediated Detector technology, recently demonstrating a record 2.1 eV resolution while focusing on improving phonon collection efficiency and implementing low- superconductors.
This paper proposes a hybrid spectroscopic architecture that couples a medium-resolution Fourier transform spectrometer with a low-resolution on-chip filterbank spectrometer to significantly reduce photon noise and enable high-sensitivity, large-field line intensity mapping at resolutions of R~1000 for ground-based and balloon-borne astronomy.
This study validates olivine as a promising candidate for the "paleo-detector" technique by using STEM to characterize heavy-ion tracks at various depths without etching, confirming that observed changes in track continuity align with SRIM simulation predictions regarding the transition between electronic and nuclear stopping power.
This paper introduces the Particle transformer (PaRT), a novel deep neural network based on self-attention that achieves high-efficiency tagging of Lorentz-boosted Higgs bosons decaying to W boson pairs in CMS data while maintaining decorrelation from jet mass, thereby enhancing the sensitivity of Standard Model measurements and beyond-the-Standard-Model searches.
