The combustion section further includes a fuel cell assembly that is disposed in the passageway. The fuel cell assembly includes a fuel cell stack having a plurality of fuel cells. The plurality of fuel cells extend from an inlet end in fluid communication with the diffusion chamber to an outlet end extending through the combustion liner and in fluid communication with the combustion chamber.

Abstract: A combustion section defines an axial direction, a radial direction, and a circumferential direction. The combustion section includes a casing that defines a diffusion chamber. A combustion liner is disposed within the diffusion chamber and defines a combustion chamber. The combustion liner is spaced apart from the casing such that a passageway is defined between the combustion liner and the casing. A fuel cell assembly is disposed in the passageway. The fuel cell assembly includes a fuel cell that extends between an inlet end and an outlet end. The inlet end receives a flow of air and fuel and the outlet end provides output products to the combustion chamber. The fuel cell extends at an angle between the inlet end and the outlet end relative to a radial projection line.

Abstract: The present disclosure relates to thermoplastic films and products formed therefrom that include additive components effectively compartmentalized based on diffusion characteristics of the additive components. For example, first and second additive components are localized on a thermoplastic film in a manner that as the additive components diffuse, they minimize or avoid interaction. Specifically, the thermoplastic film is folded over itself to create an air gap that causes the additive components to desorb, diffuse into the air gap, and then absorb into the film at a position across the air gap rather than diffusing substantially laterally across the thermoplastic film. By ensuring that the additive components diffuse up and down rather than laterally and by laterally offsetting the additive components, one or more implementations effectively compartmentalize the antagonistic components.

Abstract: A method for ablating a patient, consisting of ascertaining a CHA2DS2-VASc score for the patient and inserting a probe into the patient, so as to contact a pulmonary vein of the patient. The method further includes applying energy via the probe so as to ablate the pulmonary vein until pulmonary vein isolation (PVI) is achieved. When PVI is achieved and the CHA2DS2-VASc score is less than a preset value, ablation of the pulmonary vein is ceased. When PVI is achieved and the CHA2DS2-VASc score is greater than or equal to the preset value, energy is applied to perform a further ablation.

Abstract: Techniques and devices for producing short laser pulses based on chirping and stretching of short seed laser pulses and subsequent power amplification. Such laser pulses with relatively narrow spectral bandwidths can be used in certain laser applications where narrow spectral bandwidth laser pulses are advantageous. In the examples described in this document, the generated laser pulses with relatively narrow spectral bandwidths may have relatively long pulse durations (e.g., greater than 1 ps) due to the stretching operation in the pulse generation.
