Dynamic measurements for funny channels [PDF]
Proteins possess the uncanny ability to telegraph signals over long distances. The presence of a ligand, snugly bound to a site on one end of a molecule, can be “felt” by an effector domain several nanometers away. Determining precisely how this task is accomplished is a major challenge for structural biologists.

Quantum Gaussian channels with weak measurements
In this paper we perform a novel analysis of quantum Gaussian channels in the context of weak measurements. Suppose Alice sends classical information to Bob using a quantum channel. Suppose Bob is allowed to use only weak measurements, what would be the channel capacity? We formulate weak measurement theory in these terms and discuss the above question.

On wireless channel modelling : extraction of channel from channel measurements [PDF]
Next generation systems are using directional antennas for indoor high data rate devices. This arises a need for measurement and modelling of directional channels. Indoor environments also introduce extreme multipath behaviour into the directional channel.

Dual-channel OCT for Velocity Measurement in Microfluidic Channels
A dual-beam Optical Coherence Tomography system has been developed, using a bespoke dual optical fibre, to simultaneously image microfluidic channel structures and measure high velocity flows (presently 250μm/s) from a single optical access point.

A Gyro-Free System for Measuring the Parameters of Moving Objects
The present paper considers a new measurement concept of modeling measuring instruments for gyro-free determination of the parameters of moving objects. The proposed approach eliminates the disadvantages of the existing measuring instruments since it is ...
