Human Brain/Cloud Interface.

The Internet comprises a decentralized global system that serves humanity's collective effort to generate, process, and store data, most of which is handled by the rapidly expanding cloud. A stable, secure, real-time system may allow for interfacing the cloud with the human brain. One promising strategy for enabling such a system, denoted here as a "human brain/cloud interface" ("B/CI"), would be based on technologies referred to here as "neuralnanorobotics.

Leveraging position bias to improve peer recommendation.

With the advent of social media and peer production, the amount of new online content has grown dramatically. To identify interesting items in the vast stream of new content, providers must rely on peer recommendation to aggregate opinions of their many users. Due to human cognitive biases, the presentation order strongly affects how people allocate attention to the available content.

Chemical power for microscopic robots in capillaries.

Unlabelled: The power available to microscopic robots (nanorobots) that oxidize bloodstream glucose while aggregated in circumferential rings on capillary walls is evaluated with a numerical model using axial symmetry and time-averaged release of oxygen from passing red blood cells. Robots about 1 microm in size can produce up to several tens of picowatts, in steady state, if they fully use oxygen reaching their surface from the blood plasma. Robots with pumps and tanks for onboard oxygen storage could collect oxygen to support burst power demands two to three orders of magnitude larger.

Maintaining your health from within: controls for nanorobot swarms in fluids.

Molecular electronics and nanoscale chemical sensors could enable the construction of microscopic sensors capable of detecting patterns of chemicals as they flow passively in a fluid. Information from a large number of such devices allow the estimation of properties of tiny chemical sources in a macroscopic tissue volume. Although such devices cannot yet be fabricated, estimates of plausible device capabilities in small blood vessels allow the evaluation of their performance for typical chemicals released by tissues in response to localized injury or infection.

Mobile microscopic sensors for high resolution in vivo diagnostics.

Molecular electronics and nanoscale chemical sensors could allow the construction microscopic sensors capable of detecting patterns of chemicals in a fluid. Information from a large number of such devices flowing passively in the bloodstream allows estimates of the properties of tiny chemical sources in a macroscopic tissue volume. We use estimates of plausible device capabilities to evaluate their performance for typical chemicals released into the blood by tissues in response to localized injury or infection.

Experimental implementation of an adiabatic quantum optimization algorithm.

We report the realization of a nuclear magnetic resonance computer with three quantum bits that simulates an adiabatic quantum optimization algorithm. Adiabatic quantum algorithms offer new insight into how quantum resources can be used to solve hard problems. This experiment uses a particularly well-suited three quantum bit molecule and was made possible by introducing a technique that encodes general instances of the given optimization problem into an easily applicable Hamiltonian.
