The Effect of Topography on Target Decomposition of Polarimetric SAR Data
Remote Sensing, 2015 Polarimetric target decomposition enables the interpretation of radar images more easily, mostly based on physical assumptions, i.e., fitting physically-based scattering models to the polarimetric SAR observations.

Toward an SDG‐Based Typology for US Nonprofits
Business Strategy and the Environment, EarlyView.ABSTRACT The Sustainable Development Goals (SDGs) represent an emerging institutional logic that nonprofits must navigate alongside existing sector‐specific frameworks. Drawing on institutional logics and organizational hybridity theories, we examine how nonprofits incorporate SDGs into their missions and what this reveals about managing institutional ...

Topological Correlations in a Layer Adsorbed on a Crystal Surface [PDF]
, 1990 The incoherent scattering of electrons by a layer adsorbed at a single crystal surface is determined by the topological correlations of elements forming the adsorbed layer.

ChemistryEurope, EarlyView.The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Chiral molecular films as electron polarizers and polarization modulators
, 2012 Recent experiments on electron scattering through molecular films have shown that chiral molecules can be efficient sources of polarized electrons even in the absence of heavy nuclei as source of a strong spin-orbit interaction.

Nonlinear Incoherent Light Scattering
Zeitschrift für Naturforschung A, 1967 Classical equations are used to calculate nonlinear incoherent light scattered from two coherent beams of electromagnetic radiation of different frequencies propagating in a homogeneous plasma without magnetic field. With a suitable choice of the difference frequency, enhanced light scattering occurs near the plasma frequency.

Re-examination of the Elliott–Yafet spin-relaxation mechanism
New Journal of Physics, 2016 We analyze spin-dependent carrier dynamics due to incoherent electron–phonon scattering, which is commonly referred to as Elliott–Yafet (EY) spin-relaxation mechanism.

Designer Entropy Enables High Thermoelectric Power and Efficiency
Interdisciplinary Materials, EarlyView.Designer Entropy enables targeted control of defect and transport behavior in SnTe‐based alloys, allowing efficiency and power to be independently optimized. Radius‐matched Sb doping preserves carrier mobility and delivers superior power output, while Bi‐induced disorder suppresses mobility despite comparable efficiency.

The measurement of self-diffusion coefficients in liquid metals with quasielastic neutron scattering
EPJ Web of Conferences, 2015 Quasielastic incoherent neutron scattering (QENS) has proven to be a versatile tool to study self diffusion of atoms in liquid metals. Here it is shown, that coherent contributions to the signal in the small q limit appear as a flat and energy ...
