An Adaptive Decomposition Approach with Dipole Aggregation Model for Polarimetric SAR Data

open access: yesRemote Sensing, 2021
Polarimetric synthetic aperture radar (PolSAR) has attracted lots of attention from remote sensing scientists because of its various advantages, e.g., all-weather, all-time, penetrating capability, and multi-polarimetry.

Angular scattering of the Sahara dust aerosol [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Soil erosion aerosols can be transported considerable distances, the Sahara being one of the major sources in the world. In June 2016 the volume scattering function of the atmospheric aerosol was determined in the Sierra Nevada, Spain, at an altitude of ...

Quantum-Mechanical Scattering of Charged Black Holes

open access: yes, 1992
We describe the quantum mechanical scattering of slowly moving maximally charged black holes. Our technique is to develop a canonical quantization procedure on the parameter space of possible static classical solutions.

Total control over ultracold interactions via electric and magnetic fields [PDF]

open access: yes, 2007
The scattering length is commonly used to characterize the strength of ultracold atomic interactions, since it is the leading parameter in the low-energy expansion of the scattering phase shift.

Tunneling conductance in Superconductor/Ferromagnet junctions: a self consistent approach

open access: yes, 2008
We evaluate the tunneling conductance of clean Ferromomagnet/Superconductor junctions via a fully self-consistent numerical solution of the microscopic Bogoliubov-DeGennes equations.

Direct test of composite fermion model in quantum Hall systems

open access: yes, 1995
We show that neutron scattering and Raman scattering experiments can unambiguously determine a composite fermion parameter, viz., the effective number of Landau Levels filled by the composite fermions.

More about the $B$ and $D$ mesons in nuclear matter [PDF]

open access: yes, 2014
We calculate the shifts in decay constants of the pseudoscalar $B$ and $D$ mesons in nuclear medium in the frame work of QCD sum rules. We write those shifts in terms of the $B-N$ and $D-N$ scattering lengths and an extra phenomenological parameter ...
