Layers of genome organization are becoming increasingly better characterized, but less is known about how these structures respond to perturbation or shape changes. Low-salt swelling of isolated chromatin fibers or nuclei has been used for decades to inv
In this study, we utilize the standard scaler technique shown as follows:(1)xn=xraw-meanstdwhere xraw represents the original data, xn represents the corresponding normalized data, mean and std represent the mean and standard deviation of the original data from the training dataset after ...

This paper presents a robust proportional derivative adaptive nonsingular finite-time synergetic tracking control (PDAFS) for a parallel Delta robot system. First, a finite-time synergetic controller combined with a proportional derivative (PD) control is constructed based on an object-oriented model ...
