Fabrication of metal nanodots and nanowires by atomic force microscopy nanomachining
Lin, Heh-Nan The Society of Information Storage Systems 2007 정보저장시스템학회논문집 Vol.3 No.1
The fabrication of metal nanostructures by a combination of atomic force microscopy nanomachining on a thin polymer resist, metal coating and lift-off is reported. Nanodots with sizes and nanowires with widths ranging between 50 and 100 nm have been successfully created. The present work exemplifies the feasibility and effectiveness of using a single-layer resist in comparison with a two-layer resist. In addition, the localized surface plasmon resonance peaks of the metal nanostructures have been measured and the selective growths of zinc oxide nanowires on the metal nanostructures are demonstrated.

Background: The prognostic significance of the circulating absolute monocyte count (AMC) in patients with locally advanced hepatocellular carcinoma (HCC) is uncertain. This study was designed to assess the association of circulating AMC with survival outcomes in patients diagnosed with locally advanced or metastatic HCC receiving systemic chemotherapy. Materials and Methods: Between January 1, 2005 and December 30, 2012, locally advanced or metastatic HCC patients who had Child-Pugh stage A or B disease and received systemic chemotherapy were retrospectively enrolled. Patient features including gender, age, extrahepatic metastasis, Child-Pugh stage, serum alpha-fetoprotein(AFP) level and AMC were collected to investigate their prognostic impact on overall survival(OS). Results: A total of 216 patients were eligible for the study. The optimal cut-off value of AMC for OS analysis was $0.38{\times}10^9/L$. Median OS was 5.84 months in low-AMC group (95% confidence interval [CI], 5.23 to 6.45), and 5.21 months in high-AMC group (95% CI, 4.37 to 6.04; p=0.003). In COX multivariate analysis, elevated AMC remained as an independent prognostic factor for worse OS (HR, 1.578; 95% CI, 1.120 to 2.223, p=0.009). Conclusions: Our results indiicate that circulating AMC is confirmed to be an independent prognostic factor for OS in patients with locally advanced or metastatic HCC receiving systemic chemotherapy.

For device printing, it is important for uniform films to be printed because the morphology of the film affects the performance of the device in inkjet printing. In this study, to prepare stable and well-dispersed ink, polyacrylate and silicone surfactant BD-3033H were added to ink. Then a uniform quantum dot (QD) film was obtained by optimizing the polyacrylate and silicone surfactant contents of the ink as well as the substrate temperature. The change of the polyacrylate structure from a curly chain structure to a three-dimensional network structure blocked the outward flow of QDs. Silicone surfactant BD-3033H caused Marangoni flow and made the QDs flow inward. When the substrate temperature was increased, the solvent evaporation rate was accelerated, the contact line was pinned, and the outward flow was enhanced, which changed the film structure from convex to flat. Finally, when the polyacrylate content was 12 wt%, the silicone surfactant BD-3033H content was 0.10 wt%, the substrate temperature was 40°C, and the coffee ring effect was eliminated. A uniform QD film was printed, providing a technical guarantee for the fabrication of QD devices in the future.

The yellow tea thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae), has recently become one of the key pests causing economic damage to the fruit production of mango (Mangifera indica L.). In this study, we investigated the seasonal fluctuation of S. dorsalis populations using data mining techniques inwhich logistic regression (LR), decision tree (DT), and artificial neural networks (ANNs) were performed for cross analysis and the optimality of these three approaches. Subsequently, crucial factors that affect the population dynamics of S. dorsalis can be determined. Our results showed correctly classified instances of DT ≧ 83% by 10-fold cross-validation, which exhibited the highest degree of accuracy among the three methods followed by ANNs and LR.We anticipate that using an intelligent prediction model can increase prediction reliability to understand the occurrence and population dynamics of S. dorsalis under different environmental conditions. Therefore, our model could be useful for farmers to implement control measures against S. dorsalis and to manage its damages to plants. Furthermore, the model proposed can be used as a basis for assessing pesticide applications and for reducing excessive pesticide costs.

Decoy receptor 3 (DcR3) is a soluble receptor for Fas ligand, LIGHT and TL1A, but it also exerts effector functions. Previously, we found that DcR3 is upregulated in the serum and lesional skin of patients with psoriasis and is upregulated by EGFR activation in proliferating primary human epidermal keratinocytes. However, the functional role of intracellular DcR3 in keratinocyte differentiation is still incompletely defined. Herein, primary cultured human epidermal keratinocytes were differentiated by phorbol 12-myristate 13-acetate (PMA) treatment, calcium treatment and cell confluence, which are three standard in vitro differentiation models. We found that the constitutive expression of the DcR3 gene and protein was progressively suppressed during terminal differentiation of keratinocytes. These changes were correlated with downregulation of EGFR activation during keratinocyte differentiation. EGFR inhibition by gefitinib further decreased confluence-induced suppression of DcR3 mRNA expression, and, vice versa, knocking down DcR3 expression attenuated EGFR and EGFR ligand expression as well as EGFR activation. Under conditions without a change in cell growth, DcR3 silencing reduced the expression of involucrin and transglutaminase 1 but enhanced the induction of the terminal differentiation markers keratin 10 and loricrin. Of note, DcR3 interacted with PKCα and PKCδ and enhanced PKC activity. In keratinocytes with PKCα and PKCδ silencing, differentiation markers were differentially affected. In conclusion, DcR3 expression in keratinocytes is regulated by EGFR and forms a positive feedback loop to orchestrate constitutive EGFR and PKC activity. During differentiation, DcR3 is downregulated and involved in modulating the pattern of terminal differentiation.

Background/Aims: Cellulitis is a common infectious disease. However, the risk of cellulitis in cirrhotic patients is not well established, and whether liver cirrhosis is a risk factor for cellulitis remains unknown. This study evaluated the relationship between cellulitis and liver cirrhosis. Methods: The National Health Insurance Database, which was derived from the Taiwan National Health Insurance program, was used to identify patients. The study group consisted of 39,966 patients with liver cirrhosis, and the comparison group consisted of 39,701 randomly selected age- and sex-matched patients. Results: During the 3-year follow-up period, 2,674 (6.7%) patients with liver cirrhosis developed cellulitis, and 1,587 (4.0%) patients without liver cirrhosis developed cellulitis (p<0.001). Following a Cox`s regression analysis adjusted for age, sex, and underlying medical disorders, the cirrhotic patients demonstrated a greater risk for the occurrence of cellulitis than the non-cirrhotic patients during the 3-year period (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.55 to 1.77; p<0.001). Additionally, cirrhotic patients with complications also had a greater risk for the occurrence of cellulitis than those patients without complications (HR, 1.23; 95% CI, 1.14 to 1.33; p<0.001). Conclusions: We conclude that cirrhotic patients have a greater risk of cellulitis than non-cirrhotic patients. (Gut Liver 2012;6:482-485)

Currently, the marketing strategy in the manufacturing industry is becoming more and more competitive. Thus, the production efficiency becomes the main developing trend, which many people are now pursuing. However, the automatic production might cause resource conflicts and system deadlocks. In this study, Petri net models and analysis were used to effectively avoid deadlocks and to achieve the goal of lean production. The iPhone XS device developed by Apple is now a popular product. Consequently, this paper aims to describe its manufacturing system by using Petri net models. Meanwhile, the siphon property of Petri nets can be used to detect the deadlock in the manufacturing processes and to avoid it from occurring. Two simulation software tools, WoPeD and PIPE, were applied to conduct the experiments. The experimental results have indicated that our proposed approach is more feasible and acceptable than other existing ones.
