Abstract

This paper presents a novel spread spectrum (SS) method with a pseudo-natural sampling technique for filterless digital class-D audio amplifiers. This method is proposed to reduce the electromagnetic interference (EMI) emissions of amplifiers by lowering the output out-of-band spectral amplitudes around the pulse width modulator carrier frequency and its multiples. The main idea of this method is that the sampling frequency of the modulating signal and the carrier frequency are varied synchronously and randomly among three different values. Since the carrier frequency is variable, the polynomial interpolation Newton–Raphson (PI-NR) algorithm is modified to correct the harmonic distortion caused by uniform-sampling pulse width modulation (UPWM). Based on a field programmable gate array (FPGA), an experimental system is established to analyze the performances of the proposed method and other six reported SS methods. Experimental results show that the proposed method features the lowest total harmonic distortion (THD) of 0.009% with a 6.6 kHz, 0 dBFS (full scale) input, a relatively high signal-to-noise ratio (SNR) of 52.68 dB and a relatively high output out-of-band peak spectral amplitude reduction of 17.75 dB.

Abstract

Cytoplasmic male sterile (CMS) lines are valuable resources in plant breeding for heterosis utilization, guaranteeing quality of hybrid seeds, and genetic integrity. Nta(sua)S K326, which contains the nuclei of Nicotiana tabacum cv. K326 and cytoplasm of N. suaveolens, is currently the dominant CMS source used in tobacco leaf production in Yunnan, China. Therefore, the alternative CMS lines are required. Here, the Nta(gla)S K326 with cytoplasm of N. glauca has been generated from asymmetric somatic hybridization between protoplasts of K326 and N. glauca followed by backcrossing with K326. Flow cytometry analysis revealed that Nta(gla)S has almost identical ploidy level as that in K326. Moreover, Nta(gla)S, Nta(sua)S, and K326 plants showed similar relative growth rate, yield, and contents of several chemical components in the field. Further scaning electron microscopic observation of floral organs revealed that the Nta(gla)S has shortened filaments and shrivelled stamens, whereas the Nta(sua)S has severe degenerated and carpel-liked stamens, compared with fertile K326 plants. In addition, the expression patterns of several mitochondrial genes in Nta(gla)S, Nta(sua)S, and K326 plants were compared. Furthermore, the cytoplasm source of Nta(gla)S and Nta(sua)S could be distinguished by cleaved amplified polymorphic sequence (CAPS) analysis with chloroplast-specific universal primers. Taken together, these results showed the development of a Nicotiana CMS hybrid via asymmetric somatic hybridization, suggesting that flow cytometry analysis at early stage could facilitate and accelerate the selection process of generating CMS lines. Importantly, the Nta(gla)S provides a valuable germplasm as an alternative CMS line instead of Nta(sua)S in Nicotiana hybrid breeding. The Nicotiana CMS hybrid Nta(gla)S has been generated by asymmetric protoplast hybridization. The Nta(gla)S provides a valuable germplasm as an alternative CMS line instead of Nta(sua)S in Nicotiana hybrid breeding.

Abstract

Filterless digital class D power amplifiers usually utilize three-level uniform sampling pulse width modulation (UPWM) technique to convert the digital input signal into a UPWM signal which is used to drive the power stage. Therefore, the spectral estimation expressions for different three-level UPWM signals obtained by modulating the digital signal can be an evaluation tool for signal distortion and electromagnetic interference when filterless digital class D power amplifiers are designed. Based on the time-domain characteristics of three-level UPWM signals, the spectral estimation expressions for six types of three-level UPWM signals are proposed in this paper by using the discrete Fourier transform technique and the frequency response of the zero-order holder. According to these expressions, the relationships among the total harmonic distortion, the pulse repetition frequency and the pulse width resolution of the UPWM signal are studied. A UPWM generator test system based on field-programmable gate array is designed and implemented to measure the spectra of different UPWM signals. The measured results are compared with the calculated results obtained by the proposed expressions to verify the correctness of the proposed expressions.

41. An atypical component of RNA-directed DNA methylation machinery has both DNA methylation-dependent and -independent roles in locus-specific transcriptional gene silencing

Abstract

RNA-directed DNA methylation (RdDM) is an important de novo DNA methylation pathway in plants. RdDM mediates the transcriptional silencing of many endogenous genomic loci, most of which are transposon related. A forward genetics screen identified DTF1 (DNA-binding transcription factor 1) as a new component for RdDM in Arabidopsis. Loss-of-function mutations in DTF1 release the transcriptional silencing of RdDM target loci and reduce the accumulation of 24-nt small interfering RNAs (siRNAs) from some of the targets. Interestingly, in the dtf1 mutant plants, the release of transcriptional gene silencing at solo-LTR is accompanied by decreased siRNA accumulation but not by reduced DNA methylation. These results suggest that DTF1 is an atypical component of RdDM and has both DNA methylation-dependent and -independent roles in transcriptional gene silencing. We suggest that besides DNA methylation, siRNAs may cause some other uncharacterized epigenetic modifications that lead to transcriptional gene silencing.

Abstract

Mianning-Dechang Himalayan REE Metallogenetic Belt in Sichuan Province lies along the western margin of the Yangtze Craton. We have conducted detailed mineralogical studies on ore minerals collected from Maoniuping and Dalucao, the two largest deposits in the belt. With optical microscope, SEM/EDS, and EPMA, three rare intermetallic minerals, i.e. , zinccopperite (Cu 2 Zn), Snbearing native copper, and Cu-bearing jupiter were found to occur in the main ore along with barite, fluorite, apatite, sulfide and bastnaesite. Since the conditions under which zinccopperite and Sn- bearing native copper formed are quite unique, finding of these minerals, for the first time in domestic REE deposits, has significant implications for the genesis of the ore deposits in which they occur. In comparison with Cu-Zn intermetallic minerals in other occurrences, we propose that the formation of this REE metallogenetic belt is associated with fast upwelling of the Himalayan magma from deep source.
