Triplexer formed by disposing upon a substrate a highly confined silicon waveguide including one or more polarization-diverse lattice filters that are monolithically integrated with photodetectors, such as PIN or APD. The float has a passage extending therethrough from a first end of the float to a second end of the float, and the fishing line handling assembly is fitted in the passage. The first setting unit sets first parameters relating to a first data rate and a first communication robustness. Also disclosed is a golf cup including a cylindrical housing and a golf cup bell as described above. Some embodiments enable dynamic repositioning andor transformation of corrective optical elements responsive to a detected shift of a tracked gaze direction of a current user. Pharmaceutical compositions containing the HIV replication inhibitors; the use of the HIV replication inhibitors in the treatment of HIV; and processes for preparing the HIV replication inhibitors are also disclosed.
