Tootfinder

laptop was emitting electronics-in-distress pheromones, and it stopped working without AC power. it's old enough that I felt ok about getting a new one.
new laptop is fine, but somehow I lost my Blue Prince cloud save, and of course it isn't in my disk backups. so I'm starting over, again.
(old laptop will go to Free Geek, which might try to refurbish it, but will probably just extract a few organs for transplant, and then e-compost the rest)

Adjusting Tissue Puncture Omnidirectionally In Situ with Pneumatic Rotatable Biopsy Mechanism and Hierarchical Airflow Management in Tortuous Luminal Pathways
In situ tissue biopsy with an endoluminal catheter is an efficient approach for disease diagnosis, featuring low invasiveness and few complications. However, the endoluminal catheter struggles to adjust the biopsy direction by distal endoscope bending or proximal twisting for tissue sampling within the tortuous luminal organs, due to friction-induced hysteresis and narrow spaces. Here, we propose a pneumatically-driven robotic catheter enabling the adjustment of the sampling direction without t…
