A transformed cell line was constructed fromMythimna separata cells Ms7311 by lipofection methodTMs7311 cells were generated using a double selection tech-nique involving a selection in the antibiotic Zeocin, followedby a second round of selection by exhibiting cell characteri-zation. A cell clone expressing p35 was obtained with highlevel of AcMNPV and recombinant proteins. Compared withwild type Ms7311 cells, the cell clone showed increased resis-tance to Actinamycin D-induced apoptosis and a profoundresistance to nutrient development (PBS). When the cellclone was infected with recombinant baculoviruses express-ing secreted alkaline phosphatase (SEAP) and β-galactosi-dase, expression of the recombinant proteins from TMs7311cells exceeded that from parental Ms7311 cells. Production ofbudded virus and occlusion body was significantly higherthan that from parental cells Ms7311.

We review previously published and newly obtained crater size-frequency distributions in the inner solar system. These data indicate that the Moon and the ter- restrial planets have been bombarded by two populations of objects. Population 1, dominating at early times, had nearly the same size distribution as the present-day asteroid belt, and produced heavily cratered surfaces with a complex, multi-sloped crater size-frequency distribution. Population 2, dominating since about 3.8-3.7 Gyr, had the same size distribution as near-Earth objects （NEOs） and a much lower im- pact flux, and produced a crater size distribution characterized by a differential -3 single-slope power law in the crater diameter range 0.02 km to 100 km. Taken to- gether with the results from a large body of work on age-dating of lunar and meteorite samples and theoretical work in solar system dynamics, a plausible interpretation of these data is as follows. The NEO population is the source of Population 2 and it has been in near-steady state over the past ～ 3.7-3.8 Gyr; these objects are derived from the main asteroid belt by size-dependent non-gravitational effects that favor the ejection of smaller asteroids. However, Population 1 was composed of main belt as- teroids ejected from their source region in a size-independent manner, possibly by means of gravitational resonance sweeping during orbit migration of giant planets; this caused the so-called Late Heavy Bombardment （LHB）. The LHB began some time before ～3.9 Gyr, peaked and declined rapidly over the next ～ 100 to 300 Myr, and possibly more slowly from about 3.8-3.7 Gyr to ～2 Gyr. A third crater population （Population S） consisted of secondary impact craters that can dominate the cratering record at small diameters.

Quantum oscillations have played a major role in the history of condensed matter physics—and indeed in physics as a *** 1930,Shubnikov and de Haas(SdH)[1]discovered oscillations in the resistance of bismuth as a function of magnetic field,r(B).Because of theoretical work of Landau[2]in the same year,it was soon realized that the oscillations were periodic in 1/B:if a peak in r is observed at B=1T and another at B=0.5T,then we should see one at B=0.33 T,B=0.25T and so *** work is famous,but maybe not as much as it should be:it was the first discovery of a macroscopic effect that depends for its existence on the fact that an electron has a phase.

rapid improvement in the speed of computers has enabled realistic simulations of magnetoconvective processes in the surface layers of the Sun. The simulations now cover a wide range of features found in observations. In many cases a direct comparison with the observations is justified, and in all cases our understanding and interpretation of the observations is being improved. Current and future opportunities and difficulties will be discussed.
