On Designing Transport Networks With Latency Guarantees for Next‐Generation Services

Transactions on Emerging Telecommunications Technologies, Volume 36, Issue 8, August 2025.
This article presents an open‐source network simulator and digital twin focused on Metropolitan Area Networks (MAN). Our tool is capable of estimating average latency and delay percentiles between every pair of nodes with minimal computational effort, with the ultimate goal of seeing if the MAN is capable of supporting emerging services and ...

Holomorphic isometries from the unit ball into symmetric domains

, 2017
We construct isometric holomorphic embeddings of the unit ball into higher rank symmetric domains, first discovered by Mok, in an explicit way using Jordan triple systems, and prove uniqueness results for all domains, including the exceptional domains of

Nitrogen loss to the environment due to various nitrogen-use efficiencies during milk and beef production in Japan

Environmental Research Letters, 2020
Reactive nitrogen (Nr) is essential to livestock production, but its excess use can become a source of environment pollution, the extent of which can be evaluated by using a nitrogen (N) footprint model.
