In this work, we analyse and compare the continuous variable tripartite entanglement available from the use of two concurrent or cascaded χ(2) nonlinearities. We examine both idealized travelling-wave models and more experimentally realistic intracavity models, showing that tripartite entangled outputs are readily producible. These may be a useful resource for applications such as quantum crypt...

This paper proposes a new identity based tripartite key agreement protocol which is more efficient than the existing ID-based tripartite protocol. This protocol is based on the Joux's protocol for key agreement, and introduces signature along with key agreement to overcome man-in-the-middle attacks and to provide authentication. The new protocol resists existential forgeries against adaptively ...

Tripartite multidrug efflux systems of Gram-negative bacteria are composed of an inner membrane transporter, an outer membrane channel and a periplasmic adaptor protein. They are assumed to form ducts inside the periplasm facilitating drug exit across the outer membrane. Here we present the reconstitution of native Pseudomonas aeruginosa MexAB-OprM and Escherichia coli AcrAB-TolC tripartite Res...

The Tripartite Influence Model of body image and eating disturbance proposes that three formative influences (peer, parents, and media) affect body image and eating problems through two mediational mechanisms: internalization of the thin-ideal and appearance comparison processes. The current study evaluated this model in a sample of 325 sixth through eighth grade girls. Simple path analyses ind...

The discovery of participation of astrocytes as active elements in glutamatergic tripartite synapses (composed by functional units of two neurons and one astrocyte) has led to the construction of models of cognitive functioning in the human brain, focusing on associative learning, sensory integration, conscious processing and memory formation/retrieval. We have modelled human cognitive function...

Cadherin linkages between adjacent stereocilia and microvilli are essential for mechanotransduction and maintaining their organization. They are anchored to actin through interaction of their cytoplasmic domains with related tripartite complexes consisting of a class VII myosin and adaptor proteins: Myo7a/SANS/Harmonin in stereocilia and Myo7b/ANKS4B/Harmonin in microvilli. Here, we determine h...

The 3 × 3 Majorana neutrino mass matrix is written as a sum of 3 terms, i.e. Mν = MA +MB +MC , where MA is proportional to the identity matrix and MB,C are invariant under different Z3 transformations. This Mν is very suitable for understanding atmospheric and solar neutrino oscillations, with sin 2θatm and tan 2 θsol fixed at 1 and 0.5 respectively, in excellent agreement with present data. It...
