The power consumption and operating frequency of the extended true single-phase clock (E-TSPC)-based frequency divider is investigated. The short-circuit power and the switching power in the E-TSPC-based divider are calculated and simulated. A low-power divide-by-2/3 unit of a prescaler is proposed and implemented using a CMOS technology. Compared with the(More)
OBJECTIVE To investigate the clinical significance of cadherin 13 (CDH13) gene promoter methylation in the serum of patients with prostate cancer. METHODS This prospective study examined the methylation status of CDH13 in serum samples obtained from patients with primary prostate cancer and age-matched control subjects, using methylation-specific(More)
An empirical large-signal III-V field-effect transistor (FET) model has been developed. Three improved drain-source current (<i>I</i>-<i>V</i>) modeling equations capable of representing arbitrarily shaped transconductance (<i>Gm</i>) curves are proposed from level-1 to level-3. These models are characterized by the static dc and the multibias pulsed(More)
This paper presents the monopulse comparator incorporating with the phase-invertible variable attenuator (PIVA). The sum and difference patterns are synthesized by combining two outputs of the attenuators after setting the transmission coefficients with the in-phase and out-of-phase shifting. The prototype is designed and fabricated by using CMOS(More)
BACKGROUND Prostate cancer is a common malignancy in men, and inevitably some patients experience biochemical recurrence after radical prostatectomy. To date, there are no reliable predictors for prostate cancer recurrence, and novel predictors are urgently needed. PCDH10 (protocadherin-10) is a novel tumor suppressor gene, which is down-regulated by(More)
BACKGROUND Aberrant methylation of protocadherin 17 (PCDH17) has been reported in several human cancers. However, the methylation status of PCDH17 in prostate cancer and its clinical significance remains unclear. The aim of this study was to investigate the methylation status of PCDH17 and its clinical significance in patients with prostate cancer after(More)
BACKGROUND Protocadherin8 has been demonstrated to play critical roles in initiation and progression of several human cancers. It is frequently inactivated by promoter methylation in cancers and may be used as a potential biomarker. However, the methylation status of protocadherin8 and its clinical significance in prostate cancer remains largely unknown.(More)
BACKGROUND CDH13 is a novel tumor suppressor gene often inactivated by aberrant promoter methylation in human cancers. Previous studies have shown that CDH13 methylation correlated with advanced disease and poor prognosis in non-muscle invasive bladder cancer (NMIBC). The aim of the current study was to investigate the correlations between CDH13 methylation(More)
By site-directed mutagenesis, six insulin residues related to the insulin-receptor interaction were grafted, partially or fully, onto the corresponding position of a recombinant amphioxus insulin-like peptide (ILP) that contained the A- and B-domains of the deduced amphioxus ILP. After fermentation, purification, and enzymatic cleavage, six insulin-like(More)
In this paper, compact ultra-wideband (UWB) bandpass filters with ultra-narrow dual- and quad-notched bands are proposed using the broadside-coupled microstrip/coplanar waveguide (CPW) structure. The multiple-modes UWB operation is obtained through the CPW detached-mode resonator (DMR) and broadside-coupled microstrip/CPW transition. To avoid the existing(More)
