A hydrodynamic-based microfluidic chip consisted of two function units that could not only separate tumor cells (TCs) from whole blood but also remove residual blood cells was designed. The separation of TCs was achieved by a straight contraction-expansion array (CEA) microchannel on the front end of the chip. The addition of contractive structure brought a micro-vortex like Dean vortex that promoted cell focusing in the channel, while when cells entered the dilated region, the wall-induced lift force generated by the channel wall gave cells a push away from the wall.

- Some species, known as 'generalists,' thrive in a variety of habitats, while 'specialists' are adapted to specific environments, and their coexistence is maintained through complex interspecies interactions.
- The study aims to establish a theoretical framework for understanding how these generalist and specialist species coexist in ecosystems with both mutualistic and competitive relationships.
- Findings show that generalists are crucial for ecosystem stability, as their removal can lead to ecosystem collapse, while the loss of specialists typically does not have the same drastic effect.
The laser triangulation probe conveniently obtains surface topography data of a measured target. However, compared to the touch probe, its reliability and accuracy can be negatively affected by various factors associated with the object being measured and the probe itself. In this paper, to identify potential compensation strategies to improve the accuracy of depth measurement for laser triangulation probe, the measuring errors caused by an oil film on the measured surface, and the probe's position and orientation parameters with respect to the measuring object (including scan depth, incident angle, and azimuth angle), were studied.
