Nonlinear adiabatic optical isolator [PDF]

open access: yes, 2016
We theoretically propose a method for optical isolation based on adiabatic nonlinear sum frequency generation in a chirped quasi-phase-matching crystal with strong absorption at the generated sum frequency wave.

Gut microbiota Turicibacter strains differentially modify bile acids and host lipids

open access: yesNature Communications, 2023
Bacteria from the Turicibacter genus are prominent members of the mammalian gut microbiota and correlate with alterations in dietary fat and body weight, but the specific connections between these symbionts and host physiology are poorly understood.

Insulin-producing organoids engineered from islet and amniotic epithelial cells to treat diabetes

open access: yesNature Communications, 2019
Islet transplantation is a feasible approach to treat type I diabetes, however inflammation and poor vascularisation impair long-term engraftment. Here the authors show that incorporating human amniotic epithelial cells into islet organoids improves ...

A robust subspace based approach to feedforward control of broadband disturbances on a six-degrees-of-freedom vibration isolation set-up [PDF]

open access: yes, 2005
The contribution of this paper is twofold. First, the paper introduces a novel hybrid vibration isolation approach which uses a combination of passive and active vibration control techniques to provide additional design freedom.
