BACKGROUND: Acute intermittent porphyria (AIP) is a rare inherited disorder with extremely low prevalence. Early detection of patients with potential pathogenic hydroxymethylbilane synthase (HMBS) variants is crucial for clinical prognosis. This stud

Porphyrias are a group of inherited metabolic diseases that include eight types, each of which is caused by a mutation that affects an enzyme of the heme biosynthetic pathway. When an enzyme defect has physiological significance, it leads to overprod

Intractable Rare Dis Res
Acute intermittent porphyria (AIP) is a rare inherited metabolic disease associated with heme metabolism. Primary Sjogren's syndrome (PSS) is a common autoimmune disease. The combined presence of AIP and PSS complicates treatment. A rare case of conc

This paper proposes a spectra-folding feedback (SFFB) architecture for digital predistortion (DPD) of concurrent dual-band power amplifiers (PAs). Conventional dual-band DPD contains a dual-branch feedback path to receive the PA output signals at res

With the ever increasing demands for higher data rate, wider bandwidth is required for improving the throughput. This trend, however, imposes design challenges for the digital predistortion (DPD) in many aspects. In order to sample the broadband powe

For concurrent dual-band receiver with shared radio frequency (RF) front-ends, the received signals are prone to be contaminated by the inter-band modulation components even if the signals are located in distant frequency bands. A novel signal proces

Digital Predistorter is a cost-effective solution to compensate for the nonlinear distortions appearing in the RF power amplifiers (PAs). The indirect learning scheme is widely implemented because of its flexibility to eliminate the requirement for b

This paper presents the experimental results utilizing spectral-extrapolation digital predistortion (SE-DPD) for the linearization of very wideband mobile communication signals. With the limited feedback bandwidth, SE-DPD allows the use of analog-to-
