The wireless communication system includes a radio frequency unit and a core network cluster, and the core network cluster includes the control plane unit cluster and the user plane unit cluster.

Abstract: A process for treating aged oil by electron beam irradiation is disclosed, comprising the following steps: step 1, homogenizing the aged oil and then feeding the aged oil into a distributor; step 2, forming a liquid layer having a certain thickness on the distributor; step 3, installing and debugging an electron beam irradiation device on the distributor; step 4, installing and debugging a phased-array microwave emitter on the distributor after installing and debugging the electron beam irradiation device; step 5, turning on the electron beam irradiation device and the phased-array microwave emitter; and step 6, dividing the treated aged oil and then allowing the aged oil after dividing to enter an oil pool and a water pool for standing. Oil flows out from an upper layer of the oil pool, a lower layer of the oil pool flows back to an aged oil storage pool.

Abstract: A system for ultra-high temperature in-situ fretting fatigue experiment, includes a heat preservation cover defining a, a heating device arranged in the mounting space, a first test sample, a second test sample, and a clamping device arranged in the mounting space. The first test sample and the second test sample are arranged at an upper end of the heating device along a horizontal direction. A mortise is formed at an end of the first test sample facing towards the second test sample. A tenon mating with the mortise is formed at an end of the second test sample facing towards the first test sample. The clamping device is configured to be clamped at two ends of the mated first test sample and second test sample and to apply a periodically reciprocating loading along a length direction of the first test sample and the second test sample.

Abstract: An apparatus may include a first clock generator configured to receive an input clock signal, and generate two or more first-level clock signals of a track-and-hold circuit, a phase interpolator configured to generate an interpolated clock signals, wherein the interpolated clock signal is based on the two or more first-level clock signals, and a second clock generator configured to generate two or more second-level clock signals based on the interpolated clock signal, wherein the phase of the two or more second-level clock signals relative to the phase of a respective first-level clock signal is determined, at least in part, by the phase of the interpolated clock signal.

Abstract: Disclosed herein is a 4D printed programmable culture substrate with the self-morphing ability to accommodate the change in morphology of stem cells during differentiation. The 4D printed culture substrate includes a shape memory polymer that is configured for transformation from a first topographical shape to a second topographical shape during a predetermined time period in response to a stimulus, such as temperature. The first topographical shape may include micro-wells and the second topographical shape may include microgrooves, which can accommodate the growth and differentiation of neural stem cells.

Abstract: Biphasic tissue constructs that include a scaffold having one or more channels, a vascular portion comprising a hydrogel at least partially disposed in the one or more channels, and a first bioactive growth factor and a second bioactive growth factor different from the first bioactive growth factor, the first bioactive growth factor localized to the scaffold and the second bioactive growth factor localized to the vascular portion. The first bioactive growth factor may be bone morphogenetic protein 2 (BMP2) peptide and the second bioactive growth factor may be vascular endothelial growth factor (VEGF) peptide.

Abstract: A coaxial needle having two or more passageways for forming a biomimetic bioprinted blood vessel tubular construct. The coaxial needle has an external needle passageway and an internal needle passageway separated by an internal barrier, and having a nozzle at an end thereof. A bioink is provided flowable through the external needle passageway and a crosslinking solution is provided flowable through the internal needle passageway. The crosslinking solution contacts the bioink as the crosslinking solution and bioink exit the nozzle thereby forming a tubular blood vessel construct.

Abstract: A cardiac patch for treatment of a mammalian heart including perfusable vessels embedded integratedly between two layers of anisotropically oriented myocardial fibers. The cardiac patch is made using a dual 3D bioprinting technique using stereolithography to form an anisotropic construct and extrusion printing to form perfusion vessels. A nutrient and oxygen containing media can be provided within the perfusion vessels for growth of cells in the cardiac patch. The technique permits larger patches to be made for the treatment of cardiac damage in both small and large mammalian hearts.
