Fiber Diffraction without Fibers

open access: yesPhysical Review Letters, 2013
Postprocessing of diffraction patterns of completely randomly oriented helical particles, as measured, for example, in so-called "diffract-and-destroy" experiments with an x-ray free electron laser can yield "fiber diffraction" patterns expected of fibrous bundles of the particles. This will allow "single-axis alignment" to be performed computationally,

Fused fiber couplers for fiber photometry

open access: yesCell Reports Methods, 2023
In this issue of Cell Reports Methods, Formozov et al. present an innovative fiber photometry system that uses a fused fiber coupler (FFC) instead of a dichroic mirror to split the excitation and emission light. The FFC-based photometry system is highly flexible and can be easily reconfigured to record from different biosensors.

Effects of dietary protein and fiber at breakfast on appetite, ad libitum energy intake at lunch, and neural responses to visual food stimuli in overweight adults [PDF]

open access: yes, 2016
Increasing either protein or fiber at mealtimes has relatively modest effects on ingestive behavior. Whether protein and fiber have additive or interactive effects on ingestive behavior is not known.
