An appropriate infusible method plays a vital role as one of the key processes of the fabrication of polymer-derived ceramic fibers. In this work, ozone curing, a novel room temperature controllable curing strategy was used to prepare SiCN ceramic fibers. Some circular pores were observed on the surface of the obtained SiCN ceramic fibers. The tensile strength of the fibers was also investigated. To reveal the ozone-curing mechanisms of the PSZ fibers and the formation process of the circular pores, the FT-IR, SEM, OM, XRD and TG were characterized. The results showed that the Si–H bonds and Si-CH3 groups in the PSZ molecule were oxidized gradually to form oxygen-containing groups such as Si–OH, Si–O-Si and C = O in the ozone curing process, which contributed to the curing and weight gain of the PSZ fibers. Moreover, a hydrolysis reaction between Si-NH-Si and H2O might further accelerate the curing of the PSZ fibers. An unexpected result of the hydrolysis reaction is the formation of some circular pores on the surface layer of the PSZ fibers. This strategy provides a method to design, adjust and control the microstructure and composition of silicon-based ceramic fibers, and the obtained SiCN fibers may be used as catalyst support, bacterial culture and other fields.

Li, Yong,Li, Defa,Xing, Jianjun,Li, Shengli,Han, Yang,Han, In K. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.10

Thirty-six (20 wethers and 16 rams) adult Gansu highland finewool sheep with an average liveweight of $19.42{\pm}1.83kg$ were used. The sheep were allocated to 4 treatments and confined in individual feeding stalls. The 80 day feeding trial was divided into 2 periods of 38 and 42 days. The sheep had access to clean water and were fed chopped wheat straw ad libitum. Daily supplemented diets of 150 g for the first period and 200 g for the later period were provided. The 4 types of supplements were: Wheat bran type (I), which is the traditional feeding practice in the area and the control group; Linseed cake type (II); Linseed cake+poultry litter type (III); Poultry litter+distiller grains type (IV). The digestibility trial was conducted using a total collection method at the end of the first period in the feeding trial. The results showed that the digestibilities of DM, OM, CP, CF, NDF and ADF in group II and III were increased to more than 50%. CP and NDF digestibility in group II were significantly increased by 23.6% and 25.5% respectively over group I (p<0.01) and by 10.1% and 13.1% respectively over group III (p<0.05). The digestibility of DM, OM, CP, CF, NDF and ADF in group IV was lower than group I by 4.4 to 8.4% (p>0.05). Compared to group I, group II and III increased straw intake by 17.6% (p<0.01) and 10.8% (p<0.05). The ADG increased from 16.2 g in group I to 45.3 g and 32.8 g (p<0.01) in group II and III respectively. The ratio of supplement intake to gain decreased from 10.7 in group I to 3.9 and 5.4 (p<0.01) in group II and III respectively. The ratio of supplement cost to gain also decreased by 60.0% and 64.3%, respectively. The wool growth rate and wool strength in these 2 groups were noticeably improved. This significantly enhanced the wool's textile value. The above parameters in group IV were lower than in group I, except the ratio of supplement cost to gain. This research indicates that local low quality nitrogen resources could be used effectively and economically to improve the utilization of wheat straw fed to sheep on smallholder farms under harsh loess plateau conditions in the winter.

An Optimized CLBP Descriptor Based on a Scalable Block Size for Texture Classification

( Jianjun Li ),( Susu Fan ),( Zhihui Wang ),( Haojie Li ),( Chin-chen Chang ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.1

In this paper, we propose an optimized algorithm for texture classification by computing a completed modeling of the local binary pattern (CLBP) instead of the traditional LBP of a scalable block size in an image. First, we show that the CLBP descriptor is a better representative than LBP by extracting more information from an image. Second, the CLBP features of scalable block size of an image has an adaptive capability in representing both gross and detailed features of an image and thus it is suitable for image texture classification. This paper successfully implements a machine learning scheme by applying the CLBP features of a scalable size to the Support Vector Machine (SVM) classifier. The proposed scheme has been evaluated on Outex and CUReT databases, and the evaluation result shows that the proposed approach achieves an improved recognition rate compared to the previous research results.

Variability in the Viral Protein Linked to the Genome of Turnip Mosaic Virus Influences Interactions with eIF(iso)4Es in Brassica rapa

Plants protect against viruses through passive and ac- tive resistance mechanisms, and in most cases charac- terized thus far, natural recessive resistance to potyvi- ruses has been mapped to mutations in the eukaryotic initiation factor eIF4E or eIF(iso)4E genes. Five eIF4E copies and three eIF(iso)4E copies were detected in Brassica rapa. The eIF4E and eIF(iso)4E genes could interact with turnip mosaic virus (TuMV) viral protein linked to the genome (VPg) to initiate virus translation. From the yeast two-hybrid system (Y2H) and bimo- lecular fluorescence complementation (BiFC) assays, the TuMV-CHN2/CHN3 VPgs could not interact with BraA.eIF4E.a/c or BraA.eIF(iso)4E.c, but they could interact with BraA.eIF(iso)4E.a in B. rapa. Further analysis indicated that the amino acid substitution L186F (nt T556C) in TuMV-UK1 VPg was important for the interaction networks between the TuMV VPg and eIF(iso)4E proteins. An interaction model of the BraA. eIF(iso)4E protein with TuMV VPg was constructed to infer the effect of the significant amino acids on the interaction of TuMV VPgs-eIF(iso)4Es, particularly whether the L186F in TuMV-UK1 VPg could change the structure of the TuMV-UK1 VPg protein, which may terminate the interaction of the BraA.eIF(iso)4E and TuMV VPg protein. This study provides new insights into the interactions between plant viruses and trans- lation initiation factors to reveal the working of key amino acids.

Jianjun Huang,Xiongwei Zhang,Yafei Zhang,Xia Zou,Li Zeng 한국전자통신연구원 2014 ETRI Journal Vol.36 No.1

In this letter, we propose an unsupervised framework forspeech noise reduction based on the recent development oflow-rank and sparse matrix decomposition. The proposedframework directly separates the speech signal from noisyspeech by decomposing the noisy speech spectrogram intothree submatrices: the noise structure matrix, the clean speechstructure matrix, and the residual noise matrix. Evaluations onthe Noisex-92 dataset show that the proposed method achievesa signal-to-distortion ratio approximately 2.48 dB and 3.23 dBhigher than that of the robust principal component analysismethod and the non-negative matrix factorization method,respectively, when the input SNR is –5 dB.

The Evaluation of the Hydrogeological Parameters of a Field Pumping Test within Multi-layer Unconfined Pebble Aquifers: A Case Study

Jianjun Ma,Da Li,Man Wang 대한토목학회 2021 KSCE Journal of Civil Engineering Vol.25 No.10

This paper presents a case study of field pumping tests and the evaluation of the hydrogeological parameters of the unconfined pebble aquifers in the test site located at Shijiawan station in Luoyang City, China, which guarantees the construction safety of Metro Line 1. Multiple groups of single-well pumping tests and one group-well pumping test were conducted to obtain the aquifers' hydrogeological parameters. Then, a combination of theoretical analysis and numerical simulation was used to evaluate the aquifers' hydrogeological parameters. The analytical solutions were obtained for the unconfined, anisotropic pebble aquifers using the Neuman model. The numerical simulation was established via the finite element method (FEM). The calculation results indicate that the theoretical analysis and numerical simulation parameters are well matched. Moreover, the results of the numerical method which considers the heterogeneous and horizontal isotropic characteristics of the pebble stratum, as well as the hydrogeological parameters are more reliable than the results obtained by the theoretical analysis. The pumping tests also indicate that the supporting structure plays a significant role in waterproofing during dewatering construction.
