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 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.

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).

In the contemporary context of research, financial expenditures are escalating at an alarmingrate.This encompasses not only direct expenses associated with the research process, such asstaff, hardware, and equipment, but also the dissemination and archiving of results. Usually,these costs remain inaccessible to the public, a state of affairs that is deemed to be highlyunsatisfactory. [...]

Over the past year a new beamline dedicated to R&D for electron FLASH cancer radiation therapy and radiation biology was set up at the Photo Injector Test facility at DESY in Zeuthen (PITZ). The beamline runs in parallel to the SASE THz beamline at PITZ and is connected to it with an achromatic dogleg. [...]

The former CMS Run 2 High Level Trigger (HLT) farm is one of the largest contributors to CMS compute resources, providing about 25k job slots for offline computing. This CPU farm was initially employed as an opportunistic resource, exploited during inter-fill periods, in the LHC Run 2. [...]

To detect faint signals from weakly scattering samples, high-resolution x-ray microscopy typically requires a high photon flux. This exposes samples to high radiation doses and can cause radiation damage. [...]
