4. Efficient Frequent Item Counting in Multi-Core Hardware
(P)VLDB 2012 Reviews

peer reviewers? No Detailed Evaluation (Contribution, Pros/Cons, Errors); please number each point D1. (On W1) While the paper defines the frequent item counting problem, the overall problem setting is never stated clearly. I can imagine at least four different problem settings: 1. The input comes as a single online stream of data. 2. The input is resident on local storage that [...] z factors below 1.6 is small (definitely nowhere near an order of magnitude). It will improve the presentation of the …

Transient Optics and Plasmonics

ground (electron) and the excited (trion) states are the doublets characterized by the electron (S= +1/2, −1/2) and hole (J= +3/2, −3/2) spin projections, respectively. The selection rules for optical [...] on the photon energy ħ ω is observed, see Fig. 3.1(a). The delay time increases when ħ ω approaches the exciton resonance at 1.6638 eV (vertical line). We were able to observe a maximum delay of 350 ps at ħ ω = 1.661 eV. For short laser pulses with τ D =150 fs a strong distortion occurs, see Fig. 3.1(b). Here, …
