A resonant mirror biosensor, IAsys, and a quartz crystal microbalance (QCM) are known independently as surface sensitive analytical devices capable of label-free and in situ bioassays. In this study, an IAsys and a QCM are employed for a new study on the action mechanism of Paeoniae Radix 801 (P. radix 801) by detecting the specific interaction between P. radix 801 and endothelin-1 (ET-1). In t...

In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal output voltage and non-ideal output voltage (error voltage), in which non-ideal output voltage is created by capacitor mismatch, comparator offset, input offset, and finite ga...

We have previously reported on the inhibitory effect of Glycyrrhizae radix (Gl radix) on mouse endometrial carcinogenesis. The present study was performed to clarify the effects of Gl radix and glycyrrhizin (GL), the main part of Gl radix, on estradiol (E2)-related endometrial carcinogenesis. Both Gl radix and GL exerted a significant decrease in the COX-2, IL-1alpha and TNF-alpha mRNA expressi...

We denote by a polymorphic radix-n FFT an abstract algorithm scheme that is shared by all radix-n FFT algorithms, similar to the way polymorphic data types share. Given such polymorphic algorithm, particular radix-n algorithms can be obtained by specialization, thus need not be implemented separately. How to accomplish sharing between different radix-n algorithms is not obvious: for example the...

Modern RISC processors provide a special instruction { the fused multiplyadd (FMA) instruction a b c { to perform both a multiplication and an addition operation at the same time. In this paper newly developed radix-2, radix-4, and split-radix FFT algorithms that optimally take advantage of this powerful instruction are presented. All oating-point operations of these algorithms are executed as ...

BACKGROUND Animal studies investigating the beneficial effects of Puerariae radix on cardiovascular disease have suggested this plant possesses anti-diabetic and lipid lowering properties. However, the exact mechanism by which Puerariae radix affects lipid metabolism is currently unknown. The aim of this study was to investigate the effect of the water extract of Puerariae radix on the secretio...

In this article, a new radix-2 signed-digit number (Radix-2 sub signed-digit number) is defined and its properties for hardware realization are discussed. Until now, high speed calculation method with Radix-2 signed-digit numbers is proposed, but this method used “Compares With 2” to calculate carry. “Compares with 2” is a very simple method, but it needs very complicated hardware especially wh...

In this article, magnitude relation properties of Radix-2k SD number are discussed. Until now, the Radix-2k SD Number is proposed for the high-speed calculations for RSA Cryptograms. In RSA Cryptograms, many modulo calculations are used, and modulo calculations need a comparison between two numbers. In this article, we discussed about a magnitude relation of Radix-2k SD Number. In the first sec...
