Exact SU(2)×U(1) self-gravitating BPS global monopoles in four dimensions are constructed by dimensional reduction of eight dimensional metrics with G2 holonomy asymptotic to cones over S × S. The solutions carry two topological charges in an interesting way. They are generically axially but not spherically symmetric. This last fact is related to the isometries and asymptotic topology of the G2...

Giant planets that reside in close proximity to their host stars are subject to extreme irradiation, which gives rise to thermal ionization of trace Alkali metals in their atmospheres. On objects where the atmospheric electrical conductivity is substantial, the global circulation couples to the background magnetic field, inducing supplementary fields and altering the nature of the flow. To date...

This paper presents detailed performance status and projections for the silicon MEMS Quadruple Mass Gyroscope (QMG) – a unique high Q, lumped mass, mode-symmetric Class II Coriolis Vibratory Gyroscope (CVG) with interchangeable whole angle, self-calibration, and force rebalance mechanizations. Analysis of a QMG sealed without getter with a Q-factor of 1e3 reveals an Angle Random Walk (ARW) of 0...

Steady non-isothermal parallel-plate flow of a Newtonian fluid with a temperature dependent viscosity is considered. The viscosity is modelled by a Nahme type law. We apply axisymmetric Q finite elements to the coupled nonlinear system to obtain numerical solutions for a wide range of parameters.
