Analogue CMOS high-frequency continuouswavelet transform circuit
Electronics Letters, 1999 A 16-channel analog CMOS high-frequency continuous wavelet transform circuit has been realized. The circuit performs a time-frequency decomposition of a high-frequency input signal. A 100 MHz operating frequency, 45 MHz bandwidth, and 40 mW/channel power dissipation have been achieved using a 0.5 /spl mu/m CMOS process.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions
FEBS Letters, EarlyView.Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Analytical Model of a High-Frequency Rotary Transformer
IEEE AccessThe permanent magnet synchronous motors are widely used for the propulsion of electric vehicles. These motors have good performance, but result expensive because the permanent magnets installed on their rotor contain rare earths.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
