Abstract: A digital pre-distortion circuit includes a memoryless non-linear operating circuit, an intermodulation shaping filter circuit, and a signal combination circuit. The memoryless non-linear operating circuit performs a memoryless non-linear operation upon a transmission signal to generate a first signal, wherein the first signal is an output simulation signal of a radio frequency (RF) power amplifier under the memoryless effect, and the first signal includes a signal component corresponding to the transmission signal and a signal component corresponding to an intermodulation signal of the transmission signal. The intermodulation shaping filter circuit filters the first signal to generate a second signal, wherein the second signal simulates an intermodulation signal generated by the RF power amplifier in response to the transmission signal under a memory effect. The signal combination circuit combines the transmission signal and the second signal to generate a pre-distortion signal.

Abstract: The present application provides a structural strengthening device to improve the lateral strength of a building frame. This most basic form of this device consists of one structural (connecting) member, two beam-column connectors, and the buffering material. By connecting adjacent columns in the frame, resisting moments will be generated at the ends of the connecting member(s) during lateral deformation of the frame, and the bending moments and stresses at the base of the connected columns can be reduced. Implementation of this device does not only reduce the time and space required for structural rehabilitation of buildings, the “detachable” feature of this device also allows the owner to use this device as a temporary (reusable) or permanent rehabilitation measure.

Abstract: Example spatial transcriptomics techniques use “continuous” polony arrays on a customized gel surface for spatial barcoding. By screening polyacrylamide (PAA) gel fabrication conditions, polonies formed on a crosslinked PAA gel were shown to exhibit a continuous, homogenous DNA distribution, which is highly suited for tissue barcoding applications. Compared with widely used polonies formed in flow cells that utilize linear PAA gels, continuous polonies showed efficient DNA amplification and restriction digestion to generate capture oligo arrays, which have a significantly better spatial RNA capturing performance. In addition, the crosslinked PAA gel showed sufficient constraints on lateral RNA diffusion and provides better mechanical strength and stability for tissue mapping assays than a semifluidic linear PAA gel used by previous methods.
