To obtain the noncommutative effect, we consider the case of $B\\to \\infty(\\theta \\to\\pi/2)$. We approximate this as the smeared D1-brane background with $F_5=H=0$. In this background, the RR scalar induces an instability of the near-horizon geometry. However, it turns out that the RR scalar is nonpropagating, while the dilaton is a physically propagating mode. We calculate the s-wave absorption cross section of the dilaton. One finds $\\sigma_0^\\phi |_{B\\to\\infty} \\sim (\\tilde","authors_text":"Gungwon Kang, H.W. Lee (Inje University), Y.S.
