Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Telecom traffic and investment in developing countries : the effects of international settlement rate reductions [PDF]

Developing countries, which received about $35 billion in net settlement payments from the United States telecom carriers between 1985 and 1998, were upset by the Federal Communications Commission's (FCC) decision to slash rates, because lower rates mean
