Metal wires for terahertz wave guiding
Article Abstract:
A study is conducted on a bare metal wire, which can be used to transport terahertz (THz) pulses with virtually no dispersion, low attenuation, and with remarkable structural simplicity. It is concluded that it is possible to direct THz pulses inside containers or around corners, where line-of-sight optical access is not practical.

Evolution of complex life cycles in helminth parasites
Article Abstract:
Two essentially different processes, depending on where in the cycle a new host is inserted, evolve the complex cycles in helminths. These processes reduce mortality and facilitate transmissi on to the original definitive host.
