Shift radix systems have been introduced by Akiyama et al. as a common generalization of β-expansions and canonical number systems. In the present paper we study a variant of them, so-called symmetric shift radix systems which were introduced recently by Akiyama and Scheicher. In particular, for d ∈ N and r ∈ R let τr : Z d → Z , a = (a1, . . . , ad) 7→ a2, . . . , ad,− r1a1 + r2a2 + · · · + rd...

BACKGROUND Chronic obstructive pulmonary disease (COPD) is a common and frequently occurring respiratory disease. At present, western medicine treatment of COPD mainly focuses on symptomatic treatment. Using Chinese medicines or integrated Chinese and Western medicines to treat stable COPD has significant efficacy. In this study, we aimed to observe the effect of Radix Stemonae concentrated dec...

OBJECTIVES The objective of this study is to investigate the effects of Salviae Miltiorrhizae Radix hot aqueous extract on nitric oxide (NO) and prostaglandin E2 (PGE2 ) production and on 1,1-diphenyl-2-picryl hydrazyl (DPPH) free-radical scavenging in macrophages. METHODS Salviae Miltiorrhizae Radix(300 g) was heated at 100℃ with distilled water (2 L) for 4 hours. The extract was filtered an...

Radix scutellariae and Scutellariae-Paeoniae couple extracts are the well-known Traditional Chinese Medicine (TCM) to treat ulcerative colitis. Baicalin, wogonoside, baicalein and wogonin are the main effective ingredients in Radix scutellariae. This study was carried out to investigate the excretion profiles of baicalin, wogonoside, baicalein and wogonin in urine and feces after oral administr...

Yersinia enterocolitica, which causes yersiniosis, is a bacterium that produces biofilms effectively. The inhibition of biofilm formation provides method for preventing infections with Y. enterocolitica. In this study, the inhibitory activity enterocolitica was investigated in library 140 edible plant methanol extracts including forest products. It identified could be inhibited by 12 plants, Ag...

At present, there are no effective methods for modeling on representing sequence containing position information in some special problems. A novel varying-radix numeration system is proposed to solve this kind of problems. This varying-radix numeration system differs from common fixed radixes numeration systems. The applications of varying-radix numeration system in a First-In-Last-Out (FILO) s...

Abstract This work is part of an effort to structurally integrate self-sensing functionality into smart composite materials using embedded microsensors and local network communication nodes. Here we address the issue of data management through the development of localized processing algorithms. We demonstrate that the two-dimensional fast Fourier transform (FFT) is a useful algorithm due to its...

Abstract. The generating series of a radix-rational sequence is a rational formal power series from formal language theory viewed through a fixed radix numeration system. For each radix-rational sequence with complex values we provide an asymptotic expansion for the sequence of its Cesàro means. The precision of the asymptotic depends on the joint spectral radius of the linear representation of...

BACKGROUND Chinese medicinal herbs may use more than one species of Curcumae Radix (Yujin) is the tuberous roots of Curcumae wenyujin, C. kwangsiensis, C. phaeocaulis and C. longa. This study aimed to characterize the chemical profiles of these different species of Curcumae Radix, and develop a method for rapid discrimination of these species by ultra-high performance liquid chromatography-quad...
