Abstract Bupleuri Herba is widely distributed and traditionally used for the similar clinical application of Bupleuri Radix in Jiangsu and Anhui province in China. To elucidate the difference of material basis between Bupliuri Radix and Bupleuri Herba, a HPLC fingerprint method combined with DAD detection was developed for effective components analysis of these two herb medicines. Both flavonoi...

The radix-22 was a milestone in the design of pipelined FFT hardware architectures. Later, radix-2 extended to radix2.However, radix-2 was only proposed for single path delay feedback (SFD) architectures, but not for feedforward, and also it called multi path delay commutator (MDC) .The radix-216 feedforward Fast Fourier Transform architecture (FFT). In feedforward architectures radix-2 can be ...

We describe a high radix integer division algorithm where the divisor is prescaled and the quotient is postscaled without modifying the dividend to obtain an identity with the quotient differing from the desired integer quotient only in its lowest order high radix digit. Here the “oversized” partial remainder is bounded by the scaled divisor with at most one additional high radix digit selectio...

OBJECTIVE Oxidative damage is a critical role which involves hearing loss induced by impulse noise. That exogenous antioxidant agents reduce noise induced hearing loss (NIHL) has been well demonstrated in both animal studies and clinical practices. Choosing a stronger and more effective antioxidant is very important for treatment of NIHL. Vitamin E, α-lipoic acid, and radix astragali are the mo...

Radix Sophorae Tonkinensis (S. tonkinensis) is the processed lateral root of Sophora subprostrata (Leguminosae) that widely distributed over the southwest China. Radix Sophorae Tonkinensis has been widely used as a Chinese medicinal herb for the treatment of disease such as jaundice, inflammation, and aches. Herein, in order to investigate the effects of Radix Sophorae Tonkinensis on the metabo...

The Radix-4 Fast Fourier Transform (FFT) is widely accepted for signal processing applications in wireless communication system. Here, we present a new Radix-4 FFT which reduces the operational count by 6% lesser than standard Radix-4 FFT without losing any arithmetic accuracy. Simulation results are also given for the verification of the algorithm.

The development of a new general radix-b division algorithm, based on the Svoboda-Tung division, suitable for VLSI implementation is presented. The new algorithm overcomes the drawbacks of the Svoboda-Tung techniques that have prevented the VLSI implementation. First of all, the proposed algorithm is valid for any radix b ≥ 2; and next, it avoids the possible compensation due to overflow on the...

A new FFT architecture for real-valued signal is proposed using Radix-2 algorithm. It is based on modifying flow graph of the FFT algorithm such that it has both real and complex datapaths. A redundant operation in flow graph is replaced by imaginary part. Using folding technique RFFT architecture with any level of parallelism can be achieved. This RFFT architecture will lead to low hardware co...

A Radix-4 Quasi-cyclic shift network (QSN) for reconfigurable QC-LDPC decoders is presented in this paper. A complexity reduction technique is described to reduce the total gate count at each stage in addition to the fact that Radix-4 logarithmic barrel shifter naturally offers less number of stages compared to Radix-2. The proposed Radix-4 QSN architecture supports various code rates and all s...

An 82-year-old male presented with rash, burning, and itching on his knees that had started 4 days after the local application of Mandragora Radix sap for 3 consecutive days. A dermatological examination revealed erythematous, edematous, and scaly plaque lesions on the patient's knees. An open application test with M. Radix was performed, and the patient was diagnosed with allergic contact derm...
