Practical Switching-Based Hybrid FSO/RF Transmission and Its Performance Analysis
IEEE Photonics Journal, 2014 Hybrid free-space optical (FSO)/radio-frequency (RF) systems have emerged as a promising solution for high-data-rate wireless backhaul. We present and analyze a switching-based transmission scheme for the hybrid FSO/RF system.

Three-body spin-orbit forces from chiral two-pion exchange
, 2003 Using chiral perturbation theory, we calculate the density-dependent spin-orbit coupling generated by the two-pion exchange three-nucleon interaction involving virtual $\Delta$-isobar excitation.

Cascaded FSO-VLC Communication System [PDF]
IEEE Wireless Communications Letters, 2017 The proposed cascaded free space optics (FSO)-visible light communication (VLC) system consists of multiple VLC access points which caters the end users connected via a decode and forward relay to the FSO backhaul link. The FSO link is assumed to be affected by path-loss, pointing error, and atmospheric turbulence while the end-to-end signal-to-noise ...

Bureaucratic Politics and Aid Allocation: Evidence From the US Agency for International Development
Regulation &Governance, EarlyView.ABSTRACT We examine the impact of bureaucratic politics within the US Agency for International Development on the allocation of its development assistance. Existing studies of aid allocation have focused on donor interests, recipient needs, and recipient merit without accounting for the bureaucratic decision‐making process that helps determine these ...
