A Cayley (resp. bi-Cayley) graph on a dihedral group is called dihedrant bi-dihedrant). In 2000, classification of trivalent arc-transitive dihedrants was given by Marušič and Pisanski, several years later, non-arc-transitive order 4p or 8p (p prime) were classified Feng et al. As generalization these results, our first result presents dihedrants. Using this, complete vertex-transitive non-Cayl...

State-of-the-art climate models simulate a large spread in the projected decline of Arctic sea-ice area (SIA) over 21st century. Here we diagnose causes this intermodel using simple model that approximates future SIA based on present and sensitivity to temperatures. This accounts for 70%–95% variance, with majority arising from present-day biases. The remaining arises differences warming, some ...

Radio pulsars are thought to spin-down primarily due to torque from magnetic dipole radiation (MDR) emitted by the time-varying stellar magnetic field as the star rotates. This assumption produces a 'characteristic age' for a pulsar which has generally been assumed to be comparable to the actual age. Recent observational limits on the proper motion of pulsar B1757–24, however, revealed that the...
