Image-guided biopsy is the most common technique for breast cancer diagnosis. Although magnetic resonance imaging (MRI) has highest sensitivity in lesion detection, ultrasound (US) guidance generally preferred due to its non-invasiveness and real-time image feedback during insertion. In this work, we propose an autonomous robotic system US-guided of lesions identified on pre-operative MRI. Afte...

Abstract The present paper comprises the experimental and numerical analysis of damage fracture behavior ductile metals under non-proportional loading with compression shear preloading. For this purpose, biaxial experiments H-specimen using a pneumatic downholder for followed by failure tension stress state corresponding simulations are performed analyzed. A thermodynamically consistent anisotr...

the ground improvement using plastic board drain (pbd) in soft soil was undertaken by sand mat formation, pbd installation, preloading surcharge, and removal of surcharge. during this procedure, the sand mat formation induced an initial settlement. however, it was very difficult to estimate that settlement due to pbd installation, which frequently destroyed the instruments installed in the grou...

A series of studies have confirmed that vacuum preloading can effectively accelerate the consolidation process soft soil. In recent years, further improvement in efficiency this method is still continuing goal scholars. This paper reviews improvements techniques as well their practical applications China. The advantages and disadvantages each are discussed. It found replacing or eliminating one...

Recent development in high-speed nanotechnology applications, such as scanning probe microscopy and nanofabrication, has increased interest on the advancement of high-bandwidth flexure-guided nanopositioning systems. These systems are capable of providing motions with sub-nanometer resolution over a positioning bandwidth of a few kilohertz or more. High-speed nanopositioning devices are commonl...
