The Cosmic Ray Energetics and Mass (CREAM) timing charge detector
/ Ahn, H S ; Allison, P S ; Bagliesi, M G ; Beatty, J J ; Bigongiari, G ; Boyle, P ; Childers, J T ; Conklin, N B ; Coutu, S ; DuVernois, M A et al.
The use of detectors based on plastic scintillator with photomultiplier tubes (PMTs) is common in cosmic-ray experiments to differentiate particle charges. However, in the presence of a calorimeter, the standard method of pulse charge integration over a time longer than a PMT pulse is hampered by abundant albedo particles. [...]

After successful recovery of the first CREAM (Cosmic Ray Energetics And Mass) instrument during the 2004\/5 Antarctic campaign, the calorimeter was refurbished for the third launch, planned for December 2007. In this CREAM-III calorimeter, the optics were replaced with multi-clad fiber ribbons to enhance the light signal. [...]

Elemental Spectra from the CREAM-I Flight
/ Ahn, Hoseok ; Allison, P S ; Bagliesi, M G ; Beatty, J J ; Bigongiari, G ; Boyle, P J ; Childers, J T ; Conklin, N B ; Coutu, S ; Duvernois, M A et al.
The Cosmic Ray Energetics And Mass (CREAM) instrument is a balloon-borne experiment designed to measure the composition and energy spectra of cosmic rays of charge Z = 1 to 26 up to an energy of ∼1015 eV. CREAM had two successful flights on long-duration balloons (LDB) launched from McMurdo Station, Antarctica, in December 2004 and December 2005. [...]

Test of lepton universality with $B^{0} \rightarrow K^{*0}\ell^{+}\ell^{-}$ decays
/ LHCb Collaboration
A test of lepton universality, performed by measuring the ratio of the branching fractions of the $B^{0} \rightarrow K^{*0}\mu^{+}\mu^{-}$ and $B^{0} \rightarrow K^{*0}e^{+}e^{-}$ decays, $R_{K^{*0}}$, is presented. The $K^{*0}$ meson is reconstructed in the final state $K^{+}\pi^{-}$, which is required to have an invariant mass within 100$\mathrm{\,MeV}c^2$ of the known $K^{*}(892)^{0}$ mass. [...]

The CMS trigger system
/ CMS Collaboration
This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate of proton-proton (heavy ion) collisions. [...]
