For over two decades, the dCache project has provided open-source to satisfy ever-more demanding storage requirements. More than 80 sites worldwide rely on dCache to provide services for LHC experiments, Belle-II, Eu- XFEL, and others. [...]

Traditional filesystems organize data in directories. These directories are typically a collection of files whose grouping is based on a single criterion, e.g., the starting date of an experiment, experiment name, beamline ID, measurement device, or instrument. [...]

Among the Higgs boson decay channels, the one to tau leptons can offer insight into the properties of the Higgs boson. The structure under CP symmetry of the tau Yukawa coupling was investigated in CMS by reconstructing the decay planes of the two tau leptons and measuring their angular separation. [...]

Many extensions to the Standard Model predict new particles decaying into top quarks makingfinal states with top quarks important signatures in the search for new physics. Searches for suchmulti-top decays have been performed in different final states and using novel analysis techniques.This article summarises such recent ATLAS searches with Run 2 and Run 3 data collected at theLHC..

The Square Kilometre Array (SKA) is a next-generation radio telescope, and upon construction in 2030 the world's most sensitive one. SKA will comprise a low frequency component with almost 60 000 radio antennas on an extremely densely instrumented area of about 1 km$^2$ located in Australia. [...]

The Radio Neutrino Observatory Greenland (RNO-G) is being constructed at Summit Station in Greenland. It seeks to detect the radio emission of neutrinos interacting in the 3~km thick ice. [...]

NuRadio is an open-source, Python-based software package for the simulation, analysis and reconstruction of the radio emission from ultra-high-energy (UHE) neutrinos and cosmic rays. While NuRadio has so far mainly been used for in-ice radio neutrino detectors, such as ARIANNA, RNO-G and the future IceCube-Gen2 radio array, its modularity, provision of standard data processing steps for radio detectors, extensive documentation, and continuous integration system have allowed the LOFAR and SKA experiments to readily adopt NuRadio for the analysis of cosmic-ray air showers.This contribution will provide a brief overview of NuRadio, covering its new features and improvements to performance and usability in the past several years.

In image segmentation, preserving the topology of segmented structures like vessels, membranes, or roads is crucial. For instance, topological errors on road networks can significantly impact navigation [...]

This work presents recent advancements in precision longitudinal beam diagnostics for Free Electron Lasers (FELs), focusing on the integration of ultra-fast, zero-bias Schottky diode-based terahertz (THz) detectors and enhanced electro-optical bunch arrival-time monitors (EO-BAMs). These innovations are vital for both currently operating and forthcoming FEL facilities, where achieving sub-picosecond timing accuracy and reliable low-charge diagnostics is critical for optimal machine performance and experimental success.

Two low carbon (0.22 wt.%) carbide-free bainite (CFB) alloys were prepared by isothermal transformation at three differenttransformation temperatures. The distribution of carbon in bainitic ferrite (BF), retained austenite (RA) and martensite (M)phases was studied using a combination of in-situ high energy X-ray diffraction (HEXRD), atom probe tomography (APT) andelectron energy loss spectroscopy (EELS).
