Exploiting molecular probes to perform near‐infrared fluorescence‐guided surgery

Exploiting Force Sensitive Spiropyrans as Molecular Level Probes

Spiropyran (SP) mechanophore was synthesized into the soft or hard phase of segmented polyurethanes (SPU) and used as a molecular probe of force and orientation. Upon either tensile stretching or irradiation with UV light the SP-linked segmented polyurethane (SP-SPU) adopt a deep purple coloration and are fluorescent, demonstrating the force and UV-induced formation of the open merocyanine (MC)...

Exploiting Machine Learning Techniques to Perform Side Channel Attack

This paper proposes a novel unsupervised learning approach for Power Analysis – a form of side channel attack in Cryptanalysis. Different from existing works that exploit supervised learning framework to solve this problem, our method does not require any labeled pairs which contains {X,Y}={key, power-trace} information, but is still capable of deciphering the secret key accurately. Besides pro...

Are young surgeons competent to perform alimentary tract surgery?

BACKGROUND Assessment of competency during residency training has received increased attention recently. There has been less attention given to the competency of residents after training. HYPOTHESIS Patient outcomes for alimentary tract surgery (ATS) should be similar for surgeons who recently completed their residency training compared with more experienced surgeons, indicating that the youn...

Why do surgeons continue to perform unnecessary surgery?

Patient safety in surgery has historically suffered from a lack of physician-driven initiatives aimed at recognizing, preventing and mitigating medical errors and surgical complications [1]. In spite of a multiplicity of global patient safety initiatives, mandatory safety protocols and the introduction of surgical safety checklists, we continue to fall short of protecting our patients from prev...
