  "abstract": "By strictly adhering to the microscopic theory of composite fermions (CFs) for the Landau-level filling fractions \\nu_e = p/(2 p + 1), we reproduce, with remarkable accuracy, the surface-acoustic-wave (SAW)-based experimental results by Willett and co-workers concerning two-dimensional electron systems with \\nu_e close to 1/2. Our results imply that the electron band mass m_b, as distinct from the CF mass m_*, must undergo a substantial increase under the conditions corresponding to \\nu_e close to 1/2. We further establish that a finite mean-free path \\ell_0 is essential for the observed linearity of the longitudinal conductivity \\sigma_{xx}(q) as deduced from the SAW velocity shifts.",
