The content of functional ingredient fluctuated in E. mollis leaf. The functional ingredients biosynthesis pathways were revealed. EmNAC014 and EmMYB15 played key roles in functional ingredients biosynthesis. ABSTRACT Elaeagnus mollis Diels is a newly developed woody oil crop, and the biosynthesis and regulatory mechanism underlying functional and ...

Busbar Fault Direction Identification Using Sequences of Displacement Vectors
In this paper, a novel busbar fault direction identification scheme is presented. The proposed scheme is based on sequences of displacement vectors. The proposed algorithm is fast and simple enough to be embedded in a differential relay to assist the percentage‐restraint differential algorithm.

Standard and proposed non‐standard OCR characteristics. ABSTRACT This study introduces an advanced adaptive protection approach for AC power systems, designed to address key limitations in current clustering‐based relay coordination methods. Using K‐means, hierarchical, and spectral clustering techniques, the proposed scheme classifies grid operating ...

This paper primarily investigates the patterns of overvoltage changes during an interruption of oil‐immersed iron‐core reactors by circuit breakers and their distribution along the axial windings of the reactor, which optimises the winding structure. ABSTRACT This paper primarily investigates the patterns of overvoltage changes during an interruption ...
