BACKGROUND In this study we evaluated the minimum stimulating current associated with intraneural needle placement and sonographic appearance of intraneural injection. METHODS We inserted a needle 2 cm inside 28 pig nerves (brachial plexus in vivo), recorded the minimum current to elicit a motor response, and injected dye (5 mL) under ultrasound (US) imaging. RESULTS The minimum current to ...

Many software vendors conduct or commission penetration testing of their products. In a penetration test security experts identify entry points for attacks in a software product. The audits can be an eye-opener for development teams: they realize that security requires much more attention. However, it is unclear what lasting benefits developers can reap from penetration tests. We report from a ...

The purpose of this study was to investigate the feasibility of interventional MRI-guided local agent delivery into pig common bile duct (CBD) walls using a newly designed MR-compatible, needle-integrated balloon catheter system. We first designed a needle-integrated balloon catheter system that comprised of a 22 G MR-compatible Chiba biopsy needle and a conventional 12 mm × 2 cm balloon cathet...

In view of the plugged-out end-effector that can adapt only to a specific size tray, needle spacing and angle seedling are fixed. this paper, new type transplanting is proposed. The adopts double-cam structure automatically adjust needle, which solves problem picking seedlings for different sizes trays. Firstly, working principle 72-hole, 128-hole, 200-hole trays was analyzed. overall designed....

In geotechnical field investigations, cone penetration tests (CPT) are increasingly used for ground characterization of fine-grained soils. Test results different parameters that typically visualized in CPT based data interpretation charts. this paper we propose a novel methodology which is on supervised machine learning permits redefinition the boundaries within these charts to account unique ...
