The Millennium Development Goals have ended and the Sustainable Development Goals
have begun, marking a shift in the global health landscape. The frame of reference has …

The nature of ultrahigh-energy cosmic rays (UHECRs) at energies >10 20 eV remains a
mystery 1 . They are likely to be of extragalactic origin, but should be absorbed within ∼50 Mpc …

… The relation between the gain G of a detector and the estimated ratio R is found to be
given by Δ G / G = − 0.27 · R . Using an on-line procedure, the individual HV values are then …

The KASCADE-Grande air shower experiment [1] consists of, among others, a large
scintillator array for measurements of charged particles, N ch , and of an array of shielded …

The energy spectrum of cosmic rays between 10 16 eV and 10 18 eV, derived from measurements
of the shower size (total number of charged particles) and the total muon number of …

We report the observation of a steepening in the cosmic ray energy spectrum of heavy
primary particles at about 8× 10 16 eV. This structure is also seen in the all-particle energy …

Recent results of the KASCADE-Grande experiment provided evidence for a mild knee-like
structure in the all-particle spectrum of cosmic rays at E= 10 16.92±0.10 eV, which was found …

The KASCADE experiment measures extensive air showers induced by cosmic rays in the
energy range around the so-called knee. The data of KASCADE have been used in a …

… ) (1.72 g, 6.8 mmol) in 6 mL of THF at ambient temperature; the reaction mixture was stirred
at 0 C for 45–60 min. 2,3,4,6-Tetra-O-acetyl-α-d-mannopyranosyl bromide (1.64 g, 4.0 mmol) …

LOPES is a digital radio interferometer located at Karlsruhe Institute of Technology (KIT),
Germany, that measures radio emission from extensive air showers at MHz frequencies in …
