Enabling effective urban green space stewardship through planning: A qualitative comparative analysis in Southwest England

People and Nature, Volume 8, Issue 8, Page 2559-2575, August 2026.
Abstract Amid increasing urbanisation and biodiversity decline, ‘effective stewardship’ of urban green space (UGS) is a complex but critical nature‐based solution for long‐term environmental, social and economic gain. Combining stewardship and sense‐of‐place frameworks with European nature‐based solutions guidance, we investigate which social and ...

A Novel Area Efficient and High‐Speed BCD Adder Using CFA and Multiplexer in Quantum‐Dot Cellular Automata

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 2, Page 226-234, February 2026.
This paper proposes a new enhanced Single Digit BCD Adder (SDBA) to perform decimal addition optimally. Quantum‐dot Cellular Automata (QCA) will construct nanostructured arithmetic circuits for future computing. One of the vital structures in arithmetic structures is the Binary Coded Decimal (BCD)/Decimal Adder. The existing Decimal Adders require many
