Assessment of Technical Skills in Axillary Lymph Node Dissection.

Objective: A simulator to enable safe practice and assessment of ALND has been designed, and face, content and construct validity has been investigated.

Summary And Background Data: The reduction in the number of ALNDs conducted has led to decreased resident exposure and confidence.

Methods: A cross-sectional multicenter observational study was carried out between July 2017 and August 2018.

Toward a Common Framework and Database of Materials for Soft Robotics.

To advance the field of soft robotics, a unified database of material constitutive models and experimental characterizations is of paramount importance. This will facilitate the use of finite element analysis to simulate their behavior and optimize the design of soft-bodied robots. Samples from seventeen elastomers, namely Body Double™ SILK, Dragon Skin™ 10 MEDIUM, Dragon Skin 20, Dragon Skin 30, Dragon Skin FX-Pro, Dragon Skin FX-Pro + Slacker, Ecoflex™ 00-10, Ecoflex 00-30, Ecoflex 00-50, Rebound™ 25, Mold Star™ 16 FAST, Mold Star 20T, SORTA-Clear™ 40, RTV615, PlatSil Gel-10, Psycho Paint, and SOLOPLAST 150318, were subjected to uniaxial tensile tests according to the ASTM D412 standard.
