BACKGROUND Compound Arnebiae radix oil has been clinically applied to treat burns and scalds for a long time. However, it is unstable and inconvenient to use. The aim of this study was to prepare a compound Arnebiae radix microemulsion gel for transdermal delivery system and evaluate its characteristics. MATERIALS AND METHODS Based on the solubility of Shikonin, the active component of Arnebi...

ETHNOPHARMACOLOGICAL RELEVANCE Xiaoyaosan (XYS), composed of Radix Bupleuri, Radix Angelicae Sinensis, Radix Paeoniae Alba, Rhizoma Atractylodis Macrocephalae, Poria, Herba Menthae, Rhizoma Zingiberis Recens and Radix Glycyrrhizae, is a valuable traditional Chinese medicine (TCM) which is used for the treatment of depression in China. In the formula, Radix Bupleuri usually serves as the princip...

Fast Fourier Transform (FFT) algorithms are widely used in many areas of science and engineering. Some of the most widely known FFT algorithms are Radix-2 algorithm, Radix-4 algorithm, Split Radix algorithm, Fast Hartley transformation based algorithm and Quick Fourier transform. In this paper, the first three algorithms listed are implemented in the sequential and MPI (message passing interfac...

In this paper, two integers with two radices and the sum of the integers in the mixed radix form is represented. In the second part of the paper, more than two radices are taken and obtained the sum of the integers. Also a MATLAB code is generated to obtain the mixed radix form of the number. The extension of the same procedure is done for n-integers and nradices. The application of the mixed r...

This paper presents a new in-place pseudo linear radix sorting algorithm. The proposed algorithm, called MSL (Map Shuffle Loop) is an improvement over ARL (Maus, 2002). The ARL algorithm uses an in-place permutation loop of linear complexity in terms of input size. MSL uses a faster permutation loop searching for the next element to permute group by group, instead of element by element. The alg...

High-radix division, developing several quotient bits per clock, is usually limited by the difficulty of generating accurate high-radix quotient digits. This paper describes techniques which allow quotient digits to be inaccurate, but then refine the result. We thereby obtain dividers with slightly reduced performance, but with much simplified logic. For example, a nominal radix-64 divider can ...

An extension of the very-high radix division with prescaling and selection by rounding is presented. This extension consists in increasing the effective radix of the implementation by obtaining a few additional bits of the quotient per iteration, without increasing the complexity of the unit to obtain the prescaling factor nor the delay of an iteration. As a consequence, for some values of the ...

In this paper, radix-2 arithmetic is explored to minimize the number of additions in the multiplication by a constant. We provide the formal proof that for an N-bit constant, the maximum number of additions using radix-2 is lower than Dimitrov’s estimated upper-bound (2.N/log(N)) using double base number system (DBNS). In comparison to canonical signed digit (CSD) and DBNS, the new radix-2 reco...

Discrete Fourier transform (DFT) is one of the most important tools used in almost all fields of science and engineering. DFT can be implemented with efficient algorithms generally classified as fast Fourier transforms (FFT). The most widely used approaches are so-called the algorithms for, such as radix-2, radix 4 and split radix FFT (SRFFT). Considerable researches have carried out and result...
