The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in vacuum. However, in so-called epsilon-near-zero (ENZ) materials, light exhibits ...

As the product of overbreak (additional rock debris) and tunnel wall roughness, one characteristic is the irregular contour shape, making the final cross section larger ... HPAWJ technology into Road ...

We selectively introduce the apparatus, samples and final cooling performance of some remarkable experiments. Finally, theoretical discussions on novel cooling approach will be reviewed, including ...

Circulatory monitoring is currently limited to heart rate and blood pressure assessment in the majority of neonatal units globally. Non-invasive cardiac output monitoring (NiCO) in term and preterm ...

Stress transthoracic Doppler echocardiography (TTDE) is typically performed in the left anterior descending, and is a potentially feasible and cheap method of assessing flow velocity at rest and ...
