Although the zinc finger transcription factor Krüppel-like factor 4 (KLF4) has been shown to be a negative regulator of cell proliferation, the mechanisms underlying the posttranslational modification of KLF4, especially at the level of protein degradation, are poorly understood. Here, we show that KLF4 protein levels in quiescent cells were high, but(More)
A multi-chip system was built to provide experimental verification of a correlation-based digital algorithm, which acquires and corrects all element errors in the internal DAC of a multi-bit delta-sigma ADC. The proposed correction method does not rely on noise shaping, and hence it remains fully effective even for very low oversampling ratios (OSRs).(More)
Nowadays robot-assisted minimally invasive surgery (MIS) is popular because of numerous benefits to patients. However, the surgical performance evaluation methods have always failed to catch up with the development speed of surgical robot system technology. In this paper, a method `SOE' to evaluate surgeons' robot-assisted MIS operation skill is provided.(More)
