The multiple scattering of light by aqueous foams is systematically studied as a function of wavelength, bubble size, and liquid fraction. Results are analyzed in terms of the transport mean free path of the photons and an extrapolation length ratio for the diffuse photon concentration field. The wavelength dependence is minimal and may be attributed entirely to the wavelength dependence of the...
We present a fraction-free approach to the computation of matrix Padé systems. The method relies on determining a modified Schur complement for the coefficient matrices of the linear systems of equations that are associated to matrix Padé approximation problems. By using this modified Schur complement for these matrices we are able to obtain a fast hybrid fraction-free algorithm for their compu...
We describe a fraction free version of the Matrix Berlekamp/Massey algorithm. The algorithm computes a minimal matrix generator of linearly generated square matrix sequences over an integral domain. The algorithm performs all operations in the integral domain, so all divisions performed are exact. For scalar sequences, the matrix algorithm specializes to a more efficient algorithm than the algo...
The paper considers five fraction-free (FF) tests to determine whether a complex or a real polynomial has all its zeros inside the unit-circle. A FF test for complex polynomial is applicable to both complex and real polynomials where the FF property means that when it is applied to Gaussian or real integer coefficients, it can be completed over the respective ring of integers, i.e., it is Gauss...
We consider exact matrix decomposition by Gauss-Bareiss reduction. We investigate two aspects of the process: common row and column factors and the influence of pivoting strategies. We identify two types of common factors: systematic and statistical. Systematic factors depend on the process, while statistical factors depend on the specific data. We show that existing fraction-free QR (Gram–Schm...
This study was designed to investigate whether brain unbound concentration (C(u,brain)) is a better predictor of dopamine D(2) receptor occupancy than total brain concentration, cerebrospinal fluid concentration (C(CSF)), or blood unbound concentration (C(u,blood)). The ex vivo D(2) receptor occupancy and concentration-time profiles in cerebrospinal fluid, blood, and brain of six marketed antip...
Enhancing light-matter coupling at the level of single quanta is essential for numerous applications in quantum science. The cooperative optical response subwavelength atomic arrays has been found to open new pathways such strong couplings, while simultaneously offering access multiple spatial modes light field. Efficient single-mode free-space reported, but control over outgoing fields remaine...
