Prepared for AJ Collisionally - born family about 87
Number of objects in the Cybele population, adjacent and exterior to the asteroid main belt, has recently reached more than 1000 with good enough orbits. This allows its more detailed analysis than previously possible. Searching for collisionally-born clusters in this population we find only one statistically robust case: a family of objects about (87) Sylvia. We use a numerical model simulatin...
متن کاملPhysical and dynamical properties of the main belt triple asteroid (87) Sylvia
We present the analysis of high angular resolution observations of the triple asteroid (87) Sylvia collected with three 8–10 m class telescopes (Keck, VLT, Gemini North) and the Hubble Space Telescope. The moons’ mutual orbits were derived individually using a purely Keplerian model. We computed the position of Romulus, the outer moon of the system, at the epoch of a recent stellar occultation ...
متن کاملSylvia Xin
Solid-state nanofluidic devices have proven to be ideal systems to elucidate the physics of nanoscale ion transport. When the device confinement approaches the Debye length of ions in the fluid, new phenomena occur such as surface-charge-dominated transport and ion-selectivity. Although these effects have been understood for simple monovalent systems, application-critical divalent systems have ...
متن کاملDeliberations on and myths about OBRA '87 psychopharmacological medication regulations.
Editor’s note: The author was employed as a pharmacy consultant by the Healthcare Financing Administration (now the Centers for Medicare and Medicaid) until his retirement in 1999. He was one of the few officials who consulted with professional organizations outside government in the process of developing those regulations. The Omnibus Budget Reconciliation Act of 1987 (OBRA ’87) resulted in re...
متن کاملCollisionally Inhomogeneous Bose-Einstein Condensates
This dissertation studies solitary waves in collisionally inhomogeneous BoseEinstein condensates in a magnetic trap using a quasi-1D mean-field model. We introduce a model for Bose-Einstein condensate with spatially and temporally modulated nonlinearity. In terms of the spatially periodic nonlinear lattice, we study BECs in a lattice one of which minimum in a period either overlap with the mini...
