The field of spermatogonial stem cell (SSC) technologies provides tools for genetic improvement of cattle herds and multiple opportunities for research. Spermatogonial stems cells belong to the male germ line and as such have high developmental potential, which offers many possibilities for transfer of relevant genetic traits across herds in a timely manner. Type A spermatogonia include a very ...

   This paper deals with the development and modeling of cylindrical contact theories and also the simulation of contact forces to be applied in the manipulation of various biological micro/nanoparticles by means of the AFM. First, the simulation of contact forces in four environments has been carried out, which are the most commonly used fluid in biomanipulation. Then, the spherical and cy...

On-chip manipulation of micro-objects has long been sought to facilitate fundamental biological studies and point-of-care diagnostic systems. In recent years, research on surface acoustic wave (SAW) based micro-object manipulation (i.e., SAW acoustophoresis) has gained significant momentum due to its many advantages, such as non-invasiveness, versatility, simple fabrication, easy operation, and...

The complexity of the present data-centric world finds its expression in the increasing number of multi-indicator systems. This has led to the development of multicriteria ranking systems based on partial order. Partial order is a main pillar of structural mathematics. Partial order helps reveal why an object of interest holds a certain ranking position and how much it is subject to change if a...
