43  Abstract— A high performance hardware FFT have numerous application in instrumentation and communication systems. It describes new parallel FFT architecture which combines the split-radix algorithm with a constant geometry interconnect structure. The split-radix algorithm knows to have lower multiplicative complexity than both radix-2 as well as radix-4 algorithm. The split-radix algorithm...

A radix-16 fast Fourier transform (FFT) algorithm suitable for multiply-add instruction is proposed. The proposed radix-16 FFT algorithm requires fewer floating-point instructions than the conventional radix-16 FFT algorithm on processors that have a multiplyadd instruction. Moreover, this algorithm has the advantage of fewer loads and stores than either the radix-2, 4 and 8 FFT algorithms or t...

Kushen (Radix Sophorae Flavescentis) is the dried roots of Sophora Flavescens Ait, alkaloids and flavonoids are the main active constituents of Radix Sophorae Flavescentis. The influence of Radix Sophorae Flavescentis on the activities of CYP450 isoforms CYP2B6, CYP2C19, CYP1A2, CYP2C9, CYP3A4 and CYP2D6 were evaluated by cocktail method. The rats were randomly divided into Radix Sophorae Flave...

Study Design Retrospective analysis at a tertiary care center. Objective This study describes method of analyzing postoperative results using lateral view clinical photographs to create normalized projection ratios the glabella and radix. Methods We reviewed preoperative 15 patients. All were in Frankfort horizontal plane. calculated distances between (a) tragus cornea, (b) cornea radix, (c) gl...

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...
