[1.01] Asteroids: Radar Observations and Dynamics S. J. Ostro (JPL/Caltech) Radar delay-Doppler measurements are powerful for refining asteroid orbits because they have extremely fine fractional precision and are orthogonal to optical angle astrometry. Radar detection of a newly discovered near-Earth asteroid (NEA) secures its orbit and can add centuries to the interval over which its close Ear...

Currently, there are more than 100 confirmed multiple-planet systems. Moreover, a recent study by Kepler has identified 361 multiple-planet candidate systems. Investigating these systems would give us an important clue in understanding formation and evolution of planetary systems. In such multiple-planet systems, secular interactions among planets could play a significant role in determining th...

Foreword: American Chemical Society Division of Medicinal Chemistry. Celebrating 100 years of excellence.

ThisCentennial Issue of the Journal ofMedicinal Chemistry was conceived in order to commemorate the 100th anniversary of the Division of Medicinal Chemistry. The Journal is a fitting venue for this tribute. For the past 50 years, the Journal has been considered the flagship publication in our field anda rich repositoryof scientific advancement in the area of drug discovery. Thus, although the J...
