Tensor Product Derivative Matching for Wave Propagation in Inhomogeneous Media

We propose a tensor product derivative matching (TPDM) method to restore the accuracy of high-order finite difference time-domain (FDTD) schemes of computational electromagnetics (CEM) Figure 4 Measurement results of reverse-transmission gain and outputreturn loss for GaInP/GaAs HBT wideband amplifiers with and without emitter peaking Figure 5 Measured ZT and Z21 of GaInP/GaAs HBT wideband ampl...

Accurate photometry of extended spherically symmetric sources

We present a new method to derive reliable photometry of extended spherically symmetric sources from HST images (WFPC2, ACS/WFC and NICMOS/NIC2 cameras), extending existing studies of point sources and marginally resolved sources. We develop a new approach to accurately determine intrinsic sizes of extended spherically symmetric sources, such as star clusters in galaxies beyond the Local Group ...

Stability of Spherically Symmetric Wave Maps

We study Wave Maps from R2+1 to the hyperbolic plane H2 with smooth compactly supported initial data which are close to smooth spherically symmetric initial data with respect to some H1+μ, μ > 0. We show that such Wave Maps don’t develop singularities in finite time and stay close to the Wave Map extending the spherically symmetric data(whose existence is ensured by a theorem of Christodoulou-T...

Non-singular Spherically Symmetric Solution in Einstein-scalar-tensor Gravity

A static spherically symmetric metric in Einstein-scalar-tensor gravity theory with a scalar field potential V [φ] is non-singular for all real values of the coordinates. It does not have a black hole event horizon and there is no essential singularity at the origin of coordinates. The weak energy condition ρφ > 0 fails to be satisfied for r . 1.3rS (where rS is the Schwarzschild radius) but th...
