The three heteronemertean nominal species Ascaris longissima Gunnerus, 1770, Borlasia angliae Oken, 1815, and Nemertes borlasii Cuvier, 1816 have been considered as synonymous, denoting the same to which valid name Lineus longissimus (Gunnerus, 1770) has applied. These are type of genus-group names Sowerby, 1806, Cuver, 1816, respectively, in turn genera family-group Lineidae McIntosh, 1874, Bo...

Given a set N of radio stations located on an Euclidean space, a source station s and an integer h (16 h6 |N | − 1), the minimum bounded-hop broadcast range assignment problem consists in 8nding a range assignment for N of minimum total power consumption that allows broadcast operations from s to every station in N in at most h hops. The problem is known to be NP-hard on d-dimensional spaces fo...

High capacity optical storage and wide band networks facilitate the delivery of ultra high-resolution audio (UHRA). It is proposed that future high-definition television (HDTV) formats should embrace not only enhanced video but also enhanced audio designed for extended bandwidth, bit depth and spatial resolution. Key ideas are summarised including an ultra high-resolution source code format, ef...
