Abstract:Islanding detection is one of the indispensable protection detections for grid-connected inverters. The detection of islanding is the key factor that should be considered in the analysis of grid-connection security. The non-detection zone is the performance index of anti-islanding plan. According to the phase feature, quantitative analyses of the non-detection zone of several frequency disturbance schemes are conducted under several different coordinate systems by increasing disturbance, namely injecting third harmonic to the modulating wave that produces inverter drive signal and detects the voltage value and the total harmonic distortion of the power grid. The active current all-disturbance islanding detection scheme has been chosen as the initiative scheme of anti-islanding detection to complete the parameter design and simulation. According to the experimental result, this method is feasible to detect the island of microgrid. In this paper, the simulation model of islanding detection of microgrid is established through MATLAB/SIMULINK, and the simulation analysis of islanding phenomenon after the injection of third harmonic wave is conducted. The simulation result verifies the validity and availability of the islanding detection method.

“…Docking-The best theoretical complexes obtained by rigid docking were used as either a starting position or a target position for flexible interactive docking simulation using the BioSpring program (29). To take into account the different secondary structural elements of nNOS-PDZ while allowing a sufficient degree of freedom for flexible docking, we chose a multiple distance cut-off to define backbone particles as previously described (24).…”

“…Both proteins were converted to an augmented Elastic Network Model, which links by a spring two particles when they are closer than the cut-off distances. An electrostatic potential grid of R16 -17 was calculated using the APBS program (30), the Amber force field and 50 mM sodium and chloride ions, to guide nNOS-PDZ using a Phantom Omni Sensable haptic device (29).…”

Background: Nitric-oxide synthase (NOS) function in skeletal muscles is due to its interaction with dystrophin.
Results:We developed a structural model of NOS and dystrophin interaction by biochemical and in silico approaches. Conclusion: Our study provides insights about the proper localization of NOS in skeletal muscle. Significance: The molecular details of the interaction are crucial for gene therapy optimization to treat Duchenne patients.
“…In principle, interactive simulations provide a much lower latency approach for manipulating and exploring molecular structures [ 1 ]. Such methods provide a virtual or augmented reality framework for immersing the user within the simulation, with the aim that molecular interaction becomes as intuitive as possible [ 2 ].…”
