A regression model was estimated that points to three main drivers of cryptocurrency value: the difficulty in 'mining 'for coins; the rate of unit production; and the(More)
High-speed scanning in optical coherence tomography (OCT) often comes with either compromises in image quality, the requirement for post-processing of the acquired images, or both. We report on distortion-free OCT volumetric imaging with a dual-axis micro-electro-mechanical system (MEMS)-based handheld imaging probe. In the context of an imaging probe with(More)
For a variety of applications, the capability of simultaneous sensing and action in multiple locations that is inherent to multi-robot approaches offers potential advantages over single robot systems in robustness, efficiency, and application feasibility. At the fully distributed and reactive end of the multi-robot system spectrum, I present mathematical(More)
Bitcoin has ushered in the age of blockchain-based digital currency systems. Secured by cryptography and computing power, and distributed across a decentralized network of anonymous nodes, these novel systems could potentially disrupt the way that monetary policy is administered – moving away from today’s human-fallible central bankers and towards a(More)
