Published in 2021 at "Physical Review D"

DOI: 10.1103/physrevd.104.106018

Abstract: In this paper, we study circuit complexity in Proca theory with Nielsen’s approach and Fubini-Study (FS) metric approach. We place the fields on a lattice to gain a regularized theory, and obtain the ground state… read more here.

Published in 2017 at "Physical Review D"

DOI: 10.1103/physrevd.96.024057

Abstract: The Einstein-Proca system is studied in the case of a complex vector-field self-interacting through an appropriate potential with a global U(1) symmetry. The corresponding equations for a static, cylindrically symmetric metric and matter fields are… read more here.

Published in 2025 at "BMC Plant Biology"

DOI: 10.1186/s12870-025-06979-9

Abstract: Labor shortages and rising high labor costs are primary drivers of increased production costs in pod pepper cultivation. While mechanization represents a viable solution, current incompatibility between agronomic practices and agricultural machinery constrains its efficiency.… read more here.

DOI: 10.1186/s12870-025-07255-6

Abstract: Robust seedlings are critical for mechanized transplanting efficiency, with plant growth regulators (PGRs) playing a key role in seedling cultivation within plant factory systems. However, as a new type of PGR, limited research has focused… read more here.
