Experimental Characterization of Spurious Signals in Magnetic Nanoparticles Enhanced Microwave Imaging of Cancer

Sensors, 2021
Magnetic nanoparticles enhanced microwave imaging relies on the capability of modulating the response of such nanocomponents at microwaves by means of a (low frequency) polarizing magnetic field.

Time-dependent angularly averaged inverse transport

, 2009
This paper concerns the reconstruction of the absorption and scattering parameters in a time-dependent linear transport equation from knowledge of angularly averaged measurements performed at the boundary of a domain of interest.

Nuclear surface studies with antiprotonic atom X-rays [PDF]

, 2007
The recent and older level shifts and widths in pbar atoms are analyzed. The results are fitted by an antiproton-nucleus optical potential with two basic complex strength parameters.

On the Lower Bound to the Input and Output Mismatch of Conditionally Stable Linear Two-Ports

IEEE Journal of Microwaves, 2023
In the design of amplifier stages based on unconditionally stable linear active two-ports, the amplifier gain can be maximized through simultaneous conjugate matching with passive loads at the input and output ports.

Ginsparg-Wilson Pions Scattering in a Sea of Staggered Quarks [PDF]

, 2006
We calculate isospin 2 pion-pion scattering in chiral perturbation theory for a partially quenched, mixed action theory with Ginsparg-Wilson valence quarks and staggered sea quarks.

Electron localization in two-dimensional surface-corrugated conductors: manifestation of competing scattering mechanisms

, 2001
Transport properties of narrow two-dimensional conducting wires in which the electron scattering is caused by side edges' roughness have been studied. The method for calculating dynamic characteristics of such conductors is proposed which is based on the

Elastic electron scattering by laser-excited 138Ba( ... 6s6p 1P1) atoms [PDF]

, 1998
The results of a joint experimental and theoretical study concerning elastic electron scattering by laser-excited 138Ba( ... 6s6p 1P1) atoms are described. These studies demonstrate several important aspects of elastic electron collisions with coherently

Removal Energies and Final State Interaction in Lepton Nucleus Scattering

, 2019
We investigate the binding energy parameters that should be used in modeling electron and neutrino scattering from nucleons bound in a nucleus within the framework of the impulse approximation.

Physical Bounds to the Entropy-Depolarization Relation in Random Light Scattering [PDF]

, 2004
We present a theoretical study of multi-mode scattering of light by optically random media, using the Mueller-Stokes formalism which permits to encode all the polarization properties of the scattering medium in a real $4 \times 4$ matrix.
