  An analysis of DAMA data (as reconstructed from DAMA publications) confirms
the presence of an annual oscillation, but with a lower significance level than
that claimed by DAMA. The phase of their signal is 0.39 +/- 0.02, corresponding
to a peak value at about May 22, which is consistent with both the DAMA
estimate and the expected phase of a dark-matter signal. However, a spectrogram
analysis also shows evidence for oscillations in the frequency band 11 - 13
year-1, that are similar to oscillations found in spectrograms formed from
measurements of the decay rates of 36Cl and 32Si acquired at the Brookhaven
National Laboratory (BNL). One component of these oscillations (at 11.44
year-1) is prominent in DAMA/NaI data, at the 0.2% significance level (99.8%
confidence level). Analyses of BNL and other nuclear decay (specifically beta
decay and K-capture) measurements point to a solar influence, either by
neutrinos or by some currently unknown form of radiation. The phase of the
annual oscillation in DAMA data is compatible with an influence of dark matter,
and is unlikely to be attributable to a purely solar influence. We also find
that annual oscillations in both 133Ba decay measurements and the Troitsk
tritium-decay measurements are compatible with a cosmic influence but not with
a purely solar influence. These considerations raise the possibility that DAMA
measurements may somehow be influenced by a combination of solar neutrinos,
cosmic neutrinos, and dark matter
