Abstract: Metal powder particles for use in additive manufacturing are made by removing material from the surface of the particles using wet chemical etching to create a nanoscale texturing of the surface, increasing absorptivity by the metal powder particles of incident laser light and maintaining flowability. The nanoscale texturing has sub-wavelength features at laser wavelengths in the range 800-1100 nm. The particles are substantially spherical and have mean diameters in the range 10-70 ?m.

Abstract: Methods, devices and systems are provided for performing a random access (RA) procedure. A wireless transmit/receive unit (WTRU) may be configured to receive RA resource sets, where each of the RA resource sets is associated with a node-B directional beam, select an RA resource set from among the RA resource sets, and initiate an RA procedure based on the selected RA resource set. The RA procedure may include selecting multiple preambles which include a preamble for each resource of a plurality of resources corresponding to the selected RA resource set. The WTRU may be configured to sequentially transmit the selected multiple preambles in sequential RA transmissions, and may be configured to receive, from a node-B, in response to the RA transmissions, at least one RA response (RAR), where each of the received at least one RAR corresponds to one of the transmitted multiple preambles.

Abstract: A micro-incubator manifold for improved microfluidic configurations and systems and methods of manufacture and operation for a manifold and automated microfluidic systems are disclosed. Various embodiments relate to assays, systems, and/or devices for culturing cells or other biologic material in controlled environments and are applicable to related fields generally using microfluidic systems. Particular embodiments involve configurations that can be used with various standard automated handling systems, with active or passive loading and perfusion of medium and to provide high-throughput multi-assay automated systems for culturing, viewing, and analyzing cell growth, invasion, movement, chemotaxis or other properties. More specifically, specific embodiments relate to heat control systems for microfluidic culture plates and other automated systems for culture plates.

Abstract: A number of novel improved microfluidic configurations and systems and methods of manufacture and operation for a microfluidic invasion assay system.

Abstract: A number of novel improved microfluidic configurations and systems and methods of manufacture and operation. In one embodiment, three wells are used for independent cell culture systems in a cell culture array. In a second aspect, artificial sinusoids with artificial epithelial barriers are provided with just one (optionally shared or multiplexed) fluidic inlet and one (optionally shared or multiplexed) fluidic output, where the medium output also functions as a cellular input. A pneumatic cell loader combined with other components provides a fully automated cell culture system. Magnetic alignment of plate molds provides advantages and ease of molded manufacture.

Abstract: In one embodiment, a microfluidic structure comprises a culture chamber having an object flow inlet disposed between a pair of object flow outlets. A flow-around channel provides fluidic mass transport to the culture chamber through a perfusion barrier disposed opposite from the object flow inlet and object flow outlets. The perfusion barrier surrounds the culture chamber, defines an opposite wall of the culture chamber, and prevents cell passage into the flow around-channel. The perfusion barrier creates a low fluidic resistance path within the culture chamber, such that a flow of cells entering the culture chamber from the object flow inlet encounters a flow of media passing through the perfusion barrier. This causes the cells to take an approximately 180 degree turn and exit the culture chamber via the object flow outlets. The low fluidic resistance path allows the cells to settle onto the chamber floor without needing any physical barrier.
