Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice
Plant Biotechnology Journal, EarlyView.ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

Plant, Cell &Environment, EarlyView.ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...

ISA Transactions, 2007
In this paper, an index for measuring fragility of proportional integral derivative (PID) controllers is proposed. This index relates the losses of robustness of the control loop when controller parameters change, to the nominal robustness of the control loop. Furthermore, it defines when a PID controller is fragile, nonfragile or resilient.

Spiking Neural PID Controllers
2011A PID controller is a simple and general-purpose way of providing responsive control of dynamic systems with reduced overshoot and oscillation. Spiking neural networks offer some advantages for dynamic systems control, including an ability to adapt, but it is not obvious how to alter such a control network's parameters to shape its response curve.

For some industrial processes a small stationary control error or smooth oscillations of the process output around the set-point do not constitute hard design constraints but, however, the reduction of the information exchanged between the agents that take part in the control loop (sensors, controllers, actuators) is one of the tightest requirements ...

CSTR Control Using IMC-PID, PSO-PID, and Hybrid BBO-FF-PID Controller
2018A hybrid control approach (BBO-FF) based PID is used for optimal control of a non linear system, i.e., CSTR and this hybrid approach is compared with conventional Z-N tuned PID, IMC-PID, and another optimal control method PSO-PID. The aim of this study is to find an optimal controller for nonlinear process control systems and to achieve best desired ...

The recent progress of microelectronics enables the creation of intelligent sensors as integrated units including both a sensor and a microcontroller capable of performing many decentralized monitoring and/or control system functions. This paper shows how the robustness of such a device applied for the PID—control can be substantially increased by the ...
