Three floral traits, spikelet number per panicle (SNP), percentage of single exserted stigma (PSES) and dual exserted stigma (PDES) of a RI population with 185 lines under water stress and non-stress conditions for two years were investigated in a drought tolerance screening facility. ANOVA results showed high significance between years, lines, and water stress treatments, together with interactions among them in pairs. High phenotypic correlation was found between PSES and PDES (r=0.5424***). Based on a linkage map of 203 SSR markers, when under well-watered condition, six QTLs (qSNP-3b, qSNP-4, qSNP-11 qSNP-2, qSNP-5 and qSNP-9) were detected for SNP. Half of them had significant Q×E interactions. Three QTLs (qPSES-1, qPSES-2, qPSES-5) were found to influence PSES, including one locus (qPSES-2) having Q×E interaction. And three QTLs (qPDES-2, qPDES-5 and qPDES-8) were also detected to influence PDES. qPDES-5 was found to have Q×E interaction. The contribution rate of a single QTL varied from 0.80% to 8.83% for additive effect, and 1.86% to 15.25% for Q×E interactions. Under drought stress, six QTLs (qSNP-3a, qSNP-4, qSNP-7a, qSNP-7b, qSNP-8 and qSNP-9) were associated with SNP, including qSNP-3a and qSNP-4 with Q×E interaction. Three QTLs (qPSES-1, qPSES-10 and qPSES-12) were located on rice chromosome 1, 10 and 12 for PSES. Four QTLs (qPDES-1a, qPDES-1b, qPDES-4 and qPDES-9) were detected for PDES, including qPDES-9 with Q×E interaction. The additive effect of single QTL can only explain 1.16% to 5.84% of total variance while Q×E interaction of four loci can explain 4.25% to 11.54% of total variance for each locus. There were one to nine pairs of epistatic QTLs influencing SNP and stigma exsertion. The contribution rates of additive and epistatic effects seemed to be in a low magnitude for most cases (0.76%~9.92%) while a few QTLs or QTL pairs explained more than 10% of total variance. Some main effect QTL and epistasis were commonly detected among PSES and PDES, explaining the high positive correlation between them. Few QTLs were detected under both water stress and non-stress conditions, indicating that drought had severe impact on the genetic behaviors of both spikelet number and stigma exsertion.

Temporal coherent image segmentation and its applications
Song-Hai Zhang,Xian-Ying Li,Tao Chen,Yi-Fei Zhang,Shi-Min Hu,Ralph Martin (사)한국CDE학회 2010 한국CAD/CAM학회 국제학술발표 논문집 Vol.2010 No.8
We propose a trapped-ball method for image segmentation, which is fast, supports non-uniformly colored regions, and allows robust region segmentation even in the presence of imperfectly linked region edges. We also introduce two applications by using the trapped-ball image segmentation, for temporal coherent animations generation and editing. First, we present a system for vectorizing 2D raster format cartoon animations by the segmentation method and background construction. The output animations are visually flicker free, smaller in file size, and easy to edit. And then we present an automatic method for online video stream stylization, producing a temporally coherent output video stream, based on the trapped-ball segmentation and optical flow. Our system transforms video into an abstract style with large regions of constant color and highlighted bold edges.

BACKGROUND: Bile duct injury (BDI), which may occur during cholecystectomy procedures and living-donor liver transplantation, leads to life-altering complications and significantly increased mortality and morbidity. Tissue engineering, as an emerging method, has shown great potential to treat BDI. Here, we aimed to explore the application of small intestinal submucosa (SIS) matrix composites with bone marrow mesenchymal stem cells (BMSCs) to treat BDI in a rabbit model. METHODS: Rabbit-derived BMSCs were used as seed cells. Porcine SIS was used as the support material. Five centimetres of the common bile duct was dissected, and 1/3–1/2 of the anterior wall diameter was transversely incised to construct the rabbit BDI model. Then, SIS materials without/with BMSCs were inserted into the common bile duct of the BDI rabbits. After 1, 2, 4, and 8 weeks of implantation, the common bile duct was removed. Haematoxylin and eosin (HE) staining was used to assess pathological alterations in the common bile duct, while immunohistochemical staining and western blotting were used to detect expression of the epithelial cell markers CK19 and E-cadherin. Scanning electron microscopy was used to evaluate BMSC growth. RESULTS: Compared with BMSCs alone, SIS-attached BMSCs had increased growth. HE staining showed that the injured bile duct healed well and that the complex gradually degraded as the time from implantation increased. Immunohistochemical staining and western blotting showed that compared with the control group, the in vivo complex group had significantly elevated expression levels of CK19 and E-cadherin. CONCLUSION: BMSC implantation into SIS could improve BDI in rabbits, which might have clinical value for BDI treatment.

Purpose: This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China. Methods: An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included. Results: In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE. Conclusions: In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.

An integrated dendrite-free zinc metal electrode for corrosion inhibition in aqueous system
Yi-Fan Hu,Li-Feng Zhou,He Gong,He Jia,Peng Chen,Yi-Song Wang,Li-Ying Liu,Tao Du 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.9
Zinc ion batteries have gotten increasing attention as a potential candidate for lithium-ion batteries, due totheir high specific capacity (820 mAh·g1), energy density, and safety. Inevitably, dendrite and corrosion create sometrouble for this system. Herein, an integrated Zn electrode coated by Zn-Al metal oxides prepared by a simple spincoatingmethod was utilized to increase the rechargeability for aqueous zinc ion batteries. By coating the Zn anodewith an artificial electrolyte interface, the wettability of Zn anodes was improved and impedance was reduced. Thecoating suppressed not only the appearance of dendrite but also the formation of corrosion products. The symmetricalcells with coating have a low overpotential (43mV) and an excellent life span. Meanwhile, the applied full batteriesexhibit an improved capacity retention rate (86.67% after 120 cycles), great rate performance and low apparent activationenergy (24.6 KJ·mol1). The simple production methods and superior corrosion suppression effects provide newideas for the anode protection of aqueous system batteries.

Nucleolin (C23) is an important anti-apoptotic protein that is ubiquitously expressed in exponentially growing eukaryotic cells. In order to understand the impact of C23 in radiation therapy, we attempted to investigate the relationship of C23 expression with the radiosensitivity of human non-small cell lung cancer (NSCLC) cells. We investigated the role of C23 in activating the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs), which is a critical protein for DNA double-strand breaks (DSBs) repair. As a result, we found that the expression of C23 was negatively correlated with the radiosensitivity of NSCLC cell lines. In vitro clonogenic survival assays revealed that C23 knockdown increased the radiosensitivity of a human lung adenocarcinoma cell line, potentially through the promotion of radiation-induced apoptosis and adjusting the cell cycle to a more radiosensitive stage. Immunofluorescence data revealed an increasing quantity of ${gamma}$-H2AX foci and decreasing radiation-induced DNA damage repair following knockdown of C23. To further clarify the mechanism of C23 in DNA DSBs repair, we detected the expression of DNA-PKcs and C23 proteins in NSCLC cell lines. C23 might participate in DNA DSBs repair for the reason that the expression of DNA-PKcs decreased at 30, 60, 120 and 360 minutes after irradiation in C23 knockdown cells. Especially, the activity of DNA-PKcs phosphorylation sites at the S2056 and T2609 was significantly suppressed. Therefore we concluded that C23 knockdown can inhibit DNA-PKcs phosphorylation activity at the S2056 and T2609 sites, thus reducing the radiation damage repair and increasing the radiosensitivity of NSCLC cells. Taken together, the inhibition of C23 expression was shown to increase the radiosensitivity of NSCLC cells, as implied by the relevance to the notably decreased DNA-PKcs phosphorylation activity at the S2056 and T2609 clusters. Further research on targeted C23 treatment may promote effectiveness of radiotherapy and provide new targets for NSCLC patients.

Secured Green Communication Scheme for Interference Alignment Based Networks
Zhibin Xie,Xinquan Geng,Yunfei Chen,Kening Song,Benjamin Panful,Yajun Wang,Yinjie Su,Zhenkai Zhang,Ying Hu 한국통신학회 2020 Journal of communications and networks Vol.22 No.1
In this paper, a new security and green communicationscheme is proposed to the interference-alignment (IA) based networks. To achieve a secured communication, full-duplex receiversare utilized to transmit artificial noise (AN). Both the signals andthe ANs are used to harvest energy to realize green communication. For these reasons, the feasible conditions of this scheme areanalyzed first. Secondly, the average transmission rate, the secrecyperformance and the harvested energy are investigated. Thirdly,an optimization scheme of simultaneous wireless information andpower transfer (SWIPT) is given to optimize the information transmissionand the energy harvesting efficiency. Meanwhile, an improvedIA iteration algorithm is designed to eliminate both the ANand the interference. Furthermore, relay cooperation is consideredand its system performance is analyzed. The simulations show thatthe target average transmission rate is not affected by AN, whilethe secrecy performance can be greatly improved. The energy harvestingefficiency is also better than the traditional schemes. Asexpected, the average transmission rate further is improved withthe relay cooperation.
