The photosynthetic system of maize (Zea mays) leaves is sensitive to low temperatures and suffers from irreversible damage induced by cold exposure, making stress a major factor limiting yield. Identifying genes that improve the recovery photosynthesis in will help enhance tolerance this crop ensure stable yields. Here, we demonstrate role starch phosphorylase 2 (ZmPHOH) promoting damage. Chlorotic leaf3 (chl3), null mutant ZmPHOH, which undergoes chlorophyll degradation chlorosis earlier...
The permanent magnetic suspension (PMS) train has distinct advantages in reducing energy consumption and increasing the air gap. Aiming at problems of uncontrollable field underdamping PMS system, electromagnetic damping structure is introduced, a fuzzy linear active disturbance rejection control (Fuzzy-LADRC) method with an gap deviation integrator proposed. Firstly, magnet hybrid (PEMS) system constructed, model analysis carried out to prove that controllable observable, hardware...
The single-axis maglev system is increasingly popular as undergraduate project kits over the recent years. Though it simple and instructive, large current in electromagnet leads to overheating problem. In order enhance energy-saving performance well controller performance, this work compares three geometric modifications on iron core, upper permanent magnet floating for system. Four target cases are defined incorporate solved numerically. Moreover, numerical solutions carefully analyzed...
With the continuing increase of offshore wind farm power scale, It is urgent to propose a simplified model, which aggregates entire Into single or several aggregated turbine generators (WTGs), aiming save computing resources and improve simulation speed. A novel aggregation algorithm that considers loss submarine cable proposed, different from traditional modeling method adopts amplifying transformer as medium.

Quality protein maize (QPM) (Zea mays L.) varieties contain enhanced levels of tryptophan and lysine, exhibiting improved nutritive value for humans livestock. However, breeding QPM remains challenging due to the complex process rebalancing storage protein. This study conducted transcriptome proteome analyses investigate proteins in opaque2 (o2) QPM. We found a weak correlation between proteome, suggesting significant modulating effect post-transcriptional events on non-zein abundances...
Starch, the main form of stored energy in plants, plays an important role maize (Zea mays L.) kernel development. The Shrunken-2 (Sh2) gene encodes large subunit rate-limiting starch biosynthetic enzyme ADP-glucose pyrophosphorylase (AGPase). sh2 mutant exhibits impaired AGPase activity, resulting partial or complete loss synthesis. Here, we investigated transcriptional regulatory framework through transcriptome and co-expression network analysis using F2 population derived from reference...
The offshore wind farm is close to the load center, and its development scale getting larger larger. In order study dynamic characteristics of farms, it obviously impractical take detailed model as research object. this paper, on principle keeping external unchanged, an aggregation taking into account submarine cable capacitance effect given. addition, method internal parameters turbine generators (WTGs) collector system are Finally, a with 34 squirrel-cage induction generator (SCIG) WTGs...
Traditional control strategy for grid-side converters (GSCs) that adopts phase-locked loop (PLL) to track grid phase is easy lose stability under weak conditions. Therefore, this paper proposes a novel method GSC based on the dynamic of DC-link capacitance, which can realize self-synchronization and maintain voltage. Meanwhile, without adding additional frequency detection devices, synchronous angular (SAF) output be reflection (GAF) in real-time, then response function achieved by...

Grid-forming controlled wind turbine is the key equipment to build new power system. However, under grid fault, short-circuit current of it limited, far less than value that synchronous generator can output support fault voltage recovery. The devices converter bear limited thermal stress. model switching established and behavior grid-forming researched. It has been found adjusting frequency adopting discontinuous PWM(DPWM) effectively reduce junction temperature devices, thus increasing...

The self-synchronization controlled wind turbine has the capability of synchronizing power grid without a phase-locked loop(PLL) and provide inertia. However, current research only focus on limit its transient overcurrent under faults but does not considered how to use it. limited short-circuit output capacity turbines limits supporting effect fault voltage. In view this problem, paper improves control method inertia-synchronization turbines, add virtual excitation control. Moreover, propose...
Submarine cables are used to collect electrical energy in offshore wind farms, of which the grounding capacitance cannot be ignored.
