A New Method for Isomorphism Identification of Planetary Gear Train based on Improved Hamming Number
Jixie chuandong, 2020 The isomorphism identification is one of the indispensable processes in structure synthesis of planetary gear train.It is of great significance for the creation of novel planetary gear train with excellent transmission characteristics.A new method for ...

Radio Continuum Spectra of Planetary Nebulae
Galaxies, 2018 Radio continuum emission of planetary nebulae is a rich source of information about their structure and physical parameters. Although radio emission is well studied, planetary nebulae show higher spectral indices than expected for homogeneous sphere.

Simultaneous Evolutionary Fits for Jupiter and Saturn Incorporating Fuzzy Cores
The Astrophysical Journal LettersWith the recent realization that there likely are stably stratified regions in the interiors of both Jupiter and Saturn, we construct new nonadiabatic, inhomogeneous evolutionary models with the same microphysics for each that result at the present time ...

Characteristic Slow‐Slip Events on the Superstition Hills Fault, Southern California
Geophysical Research LettersThe Superstition Hills Fault (SHF) exhibits a rich spectrum of slip modes, including M 6+ earthquakes, afterslip, quasi‐steady creep, and both triggered and spontaneous slow slip events (SSEs). Following 13 years of quiescence, creepmeters recorded 25 mm

The maximum mass of planetary embryos formed in core-accretion models [PDF]
, 2017 We compute the maximum mass a growing planetary embryo can reach depending on the size of accreted planetesimals or pebbles, to infer the possibility of growing the cores of giant planets, and giant planets themselves.

Next-generation Improvements in Giant-exoplanet Evolutionary and Structural Models
The Astrophysical JournalMany evolutionary models of giant exoplanets still rely on simplifying assumptions that are no longer adequate, given detailed constraints from Jupiter, Saturn, and modern exoplanet observations.

New Method for Isomorphism Identification of Planetary Gear Trains based on Traversing Loop
Jixie chuandong, 2020 Isomorphism identification is one of the indispensable processes in structure synthesis of planetary gear trains. It is of great significance for the creation of novel planetary gear train with excellent transmission characteristics.

Fine Structure in Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1974 A short report is presented on the aperture synthesis radio observations of planetary nebulae performed by Terzian et al. (1974). Examples of radio maps at 8085 MHz are shown with angular resolutions of the order of 2″ to 3″.

A CO Survey of Young Planetary Nebulae
, 2005 We report the results of a sensitive survey of young planetary nebulae in the CO J=2-1 line that significantly increases the available data on warm, dense, molecular gas in the early phases of planetary nebula formation.
