Pushing the limits of radiofrequency (RF) neuronal telemetry
In a previous report it was shown that the channel capacity of an in vivo communication link using microscopic antennas at radiofrequency is severely limited by the requirement not to damage the tissue surrounding the antennas. For dipole-like antennas the strong electric field dissipates too much power into body tissues. Loop-type antennas have a strong magnetic near field and so dissipate muc...
متن کاملElectromagnetic limits to radiofrequency (RF) neuronal telemetry
The viability of a radiofrequency (RF) telemetry channel for reporting individual neuron activity wirelessly from an embedded antenna to an external receiver is determined. Comparing the power at the transmitting antenna required for the desired Channel Capacity, to the maximum power that this antenna can dissipate in the body without altering or damaging surrounding tissue reveals the severe p...
متن کاملPushing the limits of crystallography
A very serious concern of scientists dealing with crystal structure refinement, including theoretical research, pertains to the characteristic bias in calculated versus measured diffraction intensities, observed particularly in the weak reflection regime. This bias is here attributed to corrective factors for phonons and, even more distinctly, phasons, and credible proof supporting this assumpt...
متن کاملPushing the limits of SPM
Breaking the speed limit One of the serious, inherent limitations in all forms of SPM is the low imaging rate. This is because each image is built up pixel by pixel in a sequential scan of the surface. The scanning motion involves electronically controlled mechanical displacements, and usually some form of feedback is applied between a control parameter, such as tunneling current or force, and ...
متن کاملPushing the Limits of Translation Quality Estimation
Translation quality estimation is a task of growing importance in NLP, due to its potential to reduce post-editing human effort in disruptive ways. However, this potential is currently limited by the relatively low accuracy of existing systems. In this paper, we achieve remarkable improvements by exploiting synergies between the related tasks of word-level quality estimation and automatic post-...
