“…These will decrease the flux density of the early afterglow to go beyond the limits of the detector. In the era of Swift , many early optical and X‐ray afterglows will be detected by UVOT and XRT, such as GRB 050525A (Klotz et al 2005; Shao & Dai 2005), and then the parameters may be determined by early afterglow data more precisely.…”

When a cold shell sweeps up the ambient medium, a forward shock and a reverse shock will form. We analyse the reverse‐forward shocks in a wind environment, including their dynamics and emission. An early afterglow is emitted from the shocked shell, e.g. an optical flash may emerge. The reverse shock behaves differently in two approximations: the relativistic and Newtonian cases, which depend on the parameters, e.g. the initial Lorentz factor of the ejecta. If the initial Lorentz factor is much less than 114E1/453Δ−1/40,12A−1/4*,−1, the early reverse shock is Newtonian. This may take place for the wider of a two‐component jet, an orphan afterglow caused by a low initial Lorentz factor and so on. The synchrotron self‐absorption effect is significant especially for the Newtonian reverse shock case, as the absorption frequency νa is larger than the cooling frequency νc and the minimum synchrotron frequency νm for typical parameters. For the optical to X‐ray band, the flux is nearly unchanged with time during the early period, which may be a diagnostic for the low initial Lorentz factor of the ejecta in a wind environment. We also investigate the early light curves with different wind densities and compare them with those in the interstellar medium model.

“…The value of the apparent binding constant was 50-70 for homogenate (Figure 4), 15-25 for myosin B in 0.02 m KC1, and 40-60 in 0.2 m KC1 (Figure 5). Concentrations where higher values of V would be expected gave anomalous experimental results, probably because of the increase in solubility of myosin at [PCP] > 10-1 m. This is undoubtedly related to the interactions of an insoluble protein with organic ions being unlike those of a soluble protein, thus yielding varying proportions of solid and aqueous phases as described by Klotz (1953). Anionic vs. Cationic Binding Sites.…”
