The systemic drug has historically been preferred for the treatment of majority pathological conditions, particularly liver cancer. Indeed, this mode is associated with adverse reactions, toxicity, off-target accumulation, and rapid hepatic renal clearance. Numerous efforts have made to design therapeutic carriers improve retention while decreasing side effects Following medication, local administration agents allows higher 'effective' doses fewer effects, kidney Hydrogels are highly...

In this study, in order to improve the accuracy of human hand motion pattern recognition, a novel recognition method for optimizing support vector machine (SVM) by using cloud adaptive quantum chaos ions optimization (AQCIMO-SVM) algorithm is proposed. The maximum values wavelet coefficients were extracted as feature samples from de-noised surface electromyography (sEMG) signals, which collected forearm muscles several subjects, and then was inputted into an SVM classify action recognition....

ABSTRACT The dominant upward‐continuation technique used in the potential‐field geophysics industry is fast Fourier transform (FFT) technique. However, spline‐based presented this paper has some advantages over FFT spline can be to carry out level‐to‐uneven surface 2D and 3D upward continuation. An example of continuation magnetic data using shown, it evident that continued anomalies are very close theoretical values. spacing irregular. Synthetic examples continue noise‐contaminated gravity...

With its good flexibility and adaptability to the environment, soft robot has been attached great importance by majority of researchers in recent years, is widely used rehabilitation treatment, flexible grasping other fields. However, existing actuators have disadvantages such as single deformation mode, poor insufficient environmental adaptability. The reason that actuator structure too simple meet complex application scenarios. In this paper, an omnidirectional bending multi-segment...

Many achievements for soft grippers are made in the structure design and grasping of target objects. However, there limited studies on objects with different attributes by omnidirectional bending capabilities within environments containing obstacles. In this paper, drawing inspiration from multi-segment biological finger, a 3D-multi-segment pneumatic actuator (3D-MSSPA) strong envelope independent is designed manufactured. Additionally, we developed novel prototype gripper prototype. A...
