A Demand Response Energy Management Scheme for Industrial Facilities in Smart Grid
Yue Min Ding,Seung Ho Hong,Xiao Hui Li IEEE 2014 IEEE TRANSACTIONS ON INDUSTRIAL INFORMATICS - Vol.10 No.4
<P>Demand response (DR) smart grid technology provides an opportunity for electricity consumers to actively participate in the management of power systems. Industry is one of the major consumers of electric power. In this study, we propose a DR energy management scheme for industrial facilities based on the state task network (STN) and mixed integer linear programming (MILP). The scheme divides the processing tasks in industrial facilities into nonschedulable tasks (NSTs) and schedulable tasks (STs), and takes advantage of distributed energy resources (DERs) to implement DR. Based on day-ahead hourly electricity prices, the scheme determines the scheduling of STs and DERs in order to shift the demand from peak periods (with high electricity prices) to off-peak periods (with low electricity prices), which not only improves the reliability of the electric power system, but also reduces energy costs for industrial facilities.</P>

Ding Yue-ming,Wang Jing,Wang Lin,Gao Ji-Guo,Liu Rong-Mei,Li Hai-Tao 한국응용곤충학회 2021 Journal of Asia-Pacific Entomology Vol.24 No.2
The Sip1Aa protein from Bacillus thuringiensis is highly toxic to Colaphellus bowringi Baly. In order to obtain mutant proteins with higher insecticidal activity, a random recombinant library of Sip1Aa protein was con structed using error-prone PCR. A total number of 100 positive transformants were randomly selected for sequence determination, and 25 mutants (M1 to M25) were selected and expressed the respective Sip1Aa mu tants. These Sip1Aa variants had a total of 29 base mutations, with an average of 1.2 base mutations per mutant. Compared with that of the wild-type Sip1Aa protein, the insecticidal activity of the mutants M1 (A31G, Y118C, D227E), M5 (K168R) and M21 (I307T) was significantly decreased, with and LC 50 values 4 to 6 times higher than the Sip1Aa protein. The mutant M8 (R174S) showed increase in the insecticidal activity against the Colaphellus bowringi Baly was obtained, with an LC 50 value 4-fold less than the Sip1Aa protein. The results of this study provide reference for the molecular modification of Sip1Aa protein and the study of key sites of its insecticidal activity.

The level of genetic differentiation and genetic structure in a Chinese native chicken breed, Bian chicken, and two controlled chicken populations (Jinghai chicken and Youxi chicken in China) were analysed based on 29 microsatellite markers. A total of 166 distinct alleles were observed across the 3 breeds, and 32 of these alleles (19.3%) were unique to only 1 breed. Bian chicken carried the largest number of private alleles at 15 (46.9%), followed by the Jinghai chicken with 12 private alleles (37.5%). The average polymorphism information content (0.5168) and the average expected heterozygote frequency (0.5750) of the Bian chicken were the highest, and those of the Jinghai chicken were 0.4915 and 0.5505, respectively, which were the lowest. Among 29 microsatellite loci, there were 15 highly informative loci in Bian chicken, and the other 14 were reasonably informative loci. The highly informative loci in Jinghai chicken and Youxi chicken were 17 and 14 respectively. Significant deviations from the Hardy-Weinberg equilibrium were observed at several locus-breed combinations, showing a deficit of heterozygotes in many cases. As a whole, genetic differentiation among the breeds estimated by the fixation index (Fst) were at 6.7% (p<0.001). The heterozygote deficit within population (Fis) was 22.2% (p<0.001), with the highest (0.249) in Bian chicken and lowest (0.159) in Youxi chicken. These results serve as an initial step in the plan for genetic characterization and conservation of the Chinese chicken genetic resource of Bian, as well as Jinghai and Youxi chickens.

A disintegrin-like and metalloprotease (reprolysin type) with thrombospondin type 1 motif (ADAMTS1) plays a critical role in follicular rupture and represents a major advance in the proteolytic events that control ovulation. In this study, a 9,026-bp DNA sequence containing the full coding region, all 8 introns and part of the 5'and 3' untranslated region of the porcine ADAMTS1 gene was obtained. Analysis of the ADAMTS1 gene using the porcine radiation hybrid panel indicated that pig ADAMTS1 is closely linkage with microsatellite marker S0215, located on SSC13q49. The open reading frame of its cDNA covered 2,844 bp and encoded 947 amino acids. The coding region of porcine ADAMTS1 as determined by sequence alignments shared 85% and 81% identity with human and mouse cDNAs, respectively. The deduced protein contained 947 amino acids showing 85% sequence similarity both to the human and mouse proteins, respectively. Comparative sequencing of three pig breeds revealed one single nucleotide polymorphism (SNP) within exon 7 of which a G-C substitution at position 6006 changes a codon for arginine into a codon for proline. The substitution was situated within a PvuII recognition site and developed as a PCR-RFLP marker for further use in population variation investigations and association analysis with litter size. Allele frequencies of this SNP were investigated in seven pig breeds/lines. An association analysis in a new Qingping female line suggested that different ADAMTS1 genotypes have significant differences in litter size (p<0.01).
A decade of liver organoids: Advances in disease modeling
Yue Liu,Jian-Ying Sheng,Chun-Fang Yang,Junjun Ding,Yun-Shen Chan 대한간학회 2023 Clinical and Molecular Hepatology(대한간학회지) Vol.29 No.3
Liver organoids are three-dimensional cellular tissue models in which cells interact to form unique structures in culture. During the past 10 years, liver organoids with various cellular compositions, structural features, and functional properties have been described. Methods to create these advanced human cell models range from simple tissue culture techniques to complex bioengineering approaches. Liver organoid culture platforms have been used in various research fields, from modeling liver diseases to regenerative therapy. This review discusses how liver organoids are used to model disease, including hereditary liver diseases, primary liver cancer, viral hepatitis, and nonalcoholic fatty liver disease. Specifically, we focus on studies that used either of two widely adopted approaches: differentiation from pluripotent stem cells or epithelial organoids cultured from patient tissues. These approaches have enabled the generation of advanced human liver models and, more importantly, the establishment of patient-tailored models for evaluating disease phenotypes and therapeutic responses at the individual level.
A Robust and Device-Free Daily Activities Recognition System using Wi-Fi Signals

Human activity recognition is widely used in smart homes, health care and indoor monitor. Traditional approaches all need hardware installation or wearable sensors, which incurs additional costs and imposes many restrictions on usage. Therefore, this paper presents a novel device-free activities recognition system based on the advanced wireless technologies. The fine-grained information channel state information (CSI) in the wireless channel is employed as the indicator of human activities. To improve accuracy, both amplitude and phase information of CSI are extracted and shaped into feature vectors for activities recognition. In addition, we discuss the classification accuracy of different features and select the most stable features for feature matrix. Our experimental evaluation in two laboratories of different size demonstrates that the proposed scheme can achieve an average accuracy over 95% and 90% in different scenarios.

The cytoprotective and potential molecular mechanisms of Hylocereus polyrhizus protein (RFPP) were investigated on the hydrogen peroxide (H2O2)-triggered damage in normal human embryonic lung (MRC-5) cells. An MTT assay was conducted to assess the MRC-5 cell viability after exposure to H2O2 or RFPP. Cell cycle distribution and apoptosis were explored via flow cytometry. The contents of related proteins were assessed via western blot. MRC-5 cells exhibited markedly decreased cellular viability after treatment with H2O2; however, treatment with RFPP suppressed this decrease. Additionally, RFPP interference dampened H2O2-triggered intracellular apoptosis levels and increased H2O2-triggered intracellular S phase. In these processes, the contents of phosphorylated (p)-AKT along with p-mTOR proteins were downregulated in 120 µM H2O2-treated cells compared with vehicle-treated cells. Nevertheless, in MRC-5 cells inoculated with RFPP, the levels expression of these proteins were reversed. To conclude, RFPP protected MRC-5 cells from H2O2-triggered damage via activation of the PI3K/AKT/mTOR cascade.

An analysis was performed on the effects of rubber particle size on the mechanical and optical properties of the acrylonitrile-butadiene-styrene (ABS)/poly(methyl methacrylate) (PMMA) blend and the ABS/PMMA/methacrylate-butadiene-styrene (MBS) blend. This work found that when the particle size is 0.22-0.23 μm, the impact strength value of the ABS/PMMA blend is at its maximum and is the same as that of the ABS/PMMA/MBS blend. The optimum particle size is effective in toughening because it can trigger the shear yielding mechanism of the matrix. The miscibility and surface glossiness of the blends with 0.22 μm particle size were also much better than those of the blends with other particle sizes. This work provides new insights into the synergistic roles of rubber particle size and core-shell modifier in the toughening of ABS/PMMA blend with good impact toughness and high surface glossiness.
