Since knowledge of sperm morphological characteristics can play an important PROMOCODE role in semen evaluation and fertilisation, baseline data on sperm ultrastructure are required.Live spermatozoa were collected from the cauda epididymis from 64 impala rams in the Kruger National Park and 5082 spermatozoa from 40 of these impala were studied by s
Passengers commute between different modes of transportation in traffic hubs, and passenger localization is a key component for the effective functioning of these spaces.The smartphone-based localization system presented in this work is based on the 3D step and heading approach, which is adapted depending on the position of the smartphone, i.e., he
Tinkering with pre-existing genes has long been known as a major way to create new genes.Recently, however, motherless protein-coding genes have been found to have emerged de novo from ancestral non-coding DNAs.How these genes originated is not well addressed to date.Here we identified 24 hominoid-specific de novo protein-coding genes with precise
