Abstract: Embodiments include methods and apparatus for performing transmit power control. A gain application element receives a sequence of digital input samples and a digital gain signal, and combines the digital gain signal with the digital input samples to generate a sequence of gain-compensated digital samples. A power amplifier receives and amplifies an analog version of the gain-compensated digital samples in order to generate an antenna output signal. A feedback path generates an analog feedback signal from the antenna output signal, produces a sequence of digital feedback samples from the analog feedback signal, and generates difference values based on the digital feedback samples. When a specified type of constant modulus symbol is represented in the antenna output symbol, the feedback path accumulates the difference values into an accumulated error value, and produces the digital gain signal from the accumulated error value.

Abstract: A method of creating intracellular artificial nanostructures in situ, which employees a chemical precursor. The precursor does not self-assemble due to the presence of a cleavable motif linked to it. When the precursor comes inside live cells by an uptaking mechanism on the cell membrane, the cleavable motif is then to be removed by an enzymatic action of a first enzyme. Without the cleavable motif, the precursor now engages in a self-assembling process to form nanostructures within the live cells, which may cause formation of a hydrogel. Furthermore, the self-assembling process can be made reversible by employing a second enzyme which puts the cleavable motif back to the precursor, whereby dissolving the nanostructures into solution.
