Signalling for Handover in a Broadband Cellular ATM System [PDF]
This paper presents handover procedures for the Broadband Cellular ATM Access (C-ATM) system which shall provide wireless ATM access for mobile users. Beside the description of the architecture and protocol stack of the system this paper describes message sequence charts for two different handover types: radio and network handover. This differentiation

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

A signaling based approach to broadband service control. Application to access signaling [PDF]
This paper describes a new signaling based approach for the implementation of a control plane for the B-ISDN network. A control architecture is developed, with a separation between service session, access session and call. This architecture provides the guidelines for the definition of signaling protocols.

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...
