Lymphocytes of the gamma delta (γδ) T-cell lineage are evolutionary conserved and although they express rearranged antigen-specific receptors, a large proportion respond as innate effectors. γδ T-cells are poised to combat infection by responding rapidly to cytokine stimuli similar to innate lymphoid cells. This potential to initiate strong inflammatory responses necessitates that inhibitory si...

This paper offers a brief introduction to silicon photonics including the basic optical waveguide, passive optical circuit performance, the addition of doped pand njunctions adjacent to the intrinsic silicon waveguide to inject a current across the waveguide, free-carrier dispersion, performance of the variable optical attenuator (VOA), and a monolithic, dual-function splitter-VOA array circuit.

In this paper, we present an analytical expression for the resonance frequency of Helmholtz attenuators with air cavity and membrane. We derive the characteristic equations based on one-dimensional isentropic acoustic models and illustrate the eeects on the resonance frequency of certain design variations. 1 INTRODUCTION The development of high speed paper machines requires a better control of ...

In this lecture will continue our quantum-mechanical treatment of linear attenuators and linear amplifiers. Among other things, we will distinguish between phaseinsensitive and phase-sensitive amplifiers. We will also show that the attenuator and the phase-insensitive amplifier preserve classicality, i.e., their outputs are classical states when their inputs are classical states. Finally, we wi...
