Efficacy of Medical-Legal Partnerships to Address Health-Harming Legal Needs: A Systematic Review of Experimental Studies in the Field Open
Background Despite the documented success of medical-legal partnerships (MLPs), there is a dearth of robust experimental-based research on their efficacy. This review synthesizes the findings of MLP interventions and identifies opportuniti…

Theory of four wave mixing-based parametric amplification of spin-orbit modes Open
We study the generation of spin-orbit (SO) modes via four-wave mixing (FWM)-based parametric amplification. SO modes carry quantized total angular momentum (TAM), and we show that FWM processes that generate new signals conserve TAM. This …
