    1. Some birds, for example the pigeon, are considered to be able to hear very low frequency sounds.
    2. This frequency may be reduced in specific areas, or for specific types of molluscs, if a risk assessment on toxins or phytoplankton occurrence suggests a very low risk of toxic episodes.
    3. The minimum amount of cover for personal injury should be calculated so as to compensate fully and fairly all victims who have suffered very serious injuries, whilst taking into account the low frequency of accidents involving several victims and the small number of accidents in which several victims suffer very serious injuries in the course of one and the same event.
    4. The minimum amount of cover for personal injury should be calculated so as to compensate fully and fairly all victims who have suffered very serious injuries, while taking into account the low frequency of accidents involving several victims and the small number of accidents in which several victims suffer very serious injuries in the course of one and the same event.
    5. "Time-modulated ultra-wideband" (5) means the technique in which very short precisely time-controlled RF pulses are modulated in accordance with communications data by shifting pulse positions (usually called Pulse Position Modulation, PPM) channelised or scrambled in accordance with pseudo-random noise codes by PPM, then transmitted and received in the direct pulse form without using any carrier frequencies, consequently having extremely low power density over ultra-wide frequency bands.
    6. "Time constant" (6) is the time taken from the application of a light stimulus for the current increment to reach a value of 1-1/e times the final value (i.e., 63 % of the final value). "Time-modulated ultra-wideband" (5) means the technique in which very short precisely time-controlled RF pulses are modulated in accordance with communications data by shifting pulse positions (usually called Pulse Position Modulation, PPM) channelised or scrambled in accordance with pseudo-random noise codes by PPM, then transmitted and received in the direct pulse form without using any carrier frequencies, consequently having extremely low power density over ultra-wide frequency bands. It is also known as Impulse Radio.
    7. Nano-electronics, photonics and integrated micro/nano-systems: process, device, design and testing technologies and methodologies to improve size, density, performance, energy efficiency, manufacturing and cost-effectiveness for components, systems-on-a-chip, systems-in-a-package and integrated systems; basic photonic components for wide range of applications including ultra fast components; radio frequency (RF) systems; high-performance/high-density data storage systems; very large area/highly integrated display solutions; sensing, actuating, vision and imaging devices; ultra low power systems, power components, alternative energy sources/storage; heterogeneous technologies/systems integration; smart systems; multi-functional integrated micro-nano-bio-info-systems; large-area electronics; integration in different materials/objects; interfacing with living organisms; (self-)assembly of molecules or atoms into stable structures.
