A microflow apparatus for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts. The posts are spaced across the width of a collection region in the flow path, extending between the upper and lower surfaces thereof; they have rectilinear surfaces, have arcuate cross-sections, and are randomly arranged so as to disrupt streamlined flow. Sequestering agents, such as Abs, are attached to all surfaces in the collection region via a hydrophilic coating, preferably a hydrogel containing isocyanate moieties or a PEG or polyglycine of substantial length, and are highly effective in capturing cells or other targeted biomolecules as a result of such streamlined flow disruption.

A radial-flow aspirator shut-off valve arranged in series with the aspirator may be controlled to enable or disable motive flow through the aspirator, and motive flow may enter the valve in a direction perpendicular to a motive flow axis of the aspirator when the valve is open.

A network element disposed in a network, where the network element implements a process to manage load distribution across a plurality of network interfaces of the network. The network element redirects traffic flow directed toward the plurality of network interfaces in response to changes in configuration of the plurality of network interfaces, where each traffic flow is a set of protocol data units (PDUs), having an ordered delivery requirement, and where the PDUs are transmitted across the network between a source node and a destination node. The redirection process minimizes data traffic flow disruption when the load distribution is determined using a set of load distribution tables instead of a hashing algorithm.
