The forbidden pitch "dip" in the critical dimension (CD) through the pitch curve is a well-known optical proximity effect. The CD and CD process window near the "dip",usually found near a pitch range of 1.1 to 1.4 wavelength/ NA (numerical aperture),is smaller when compared with other pitches. This is caused by inadequate imaging contrast for an unequal line and space grating. Although this effect is relatively well-known, its relationship with typical process condition parameters,such as the effective image blur caused by the photo-acid diffusion during the post exposure bake or the aberration in the imaging lens, has not been systematically studied. In this paper, we will examine the correlation between the image blur and the effect on the CD, including the decrease in the CD value (the depth of the "dip") and the CD process window. We find that both the decrease in the CD value and the focus latitude near the forbidden pitch correlate very well with the effective Gaussian image blur. Longer effective diffusion length correlates well with a smaller process window and a deeper CD "dip". We conclude that the dip depth is very sensitive to the change in image contrast. 展开更多

The proteinase is secreted from the cell as an inactive zymogen. In vivo it is postulated that activation of progelationase A (proMMP-2) takes place on the cell surface mediated by membrane-type matrix metalloproteinases (MT-MMPs). Recent studies have demonstrated that proMMP-2 is recruited to the cell surface by interacting with tissue inhibitor of metalloproteinases-2 (TIMP-2) bound to MT1MMP by forming a ternary complex. bee MT1-MMP closely located to the ternary complex then activates proMMP-2 on the cell surface. MT1-MMP is found in cultured invasive cancer cells at the invadopodia. The MTMMP/TIMP-2/ MMP- 2 system t bus provides localized expression of proteolysis of the extracellular matrix required for cell migration. 展开更多

In order to ensure the security of the property-based remote attestation scheme, an improved, more efficient, forrml security model of property-based remote attestation is proposed, with which we prove that the user platform satis- fies the security property requirements predefmed by a remote relying party. Under the co-Corrtautational Diffie-Helknan (CDH) assumption, the proposed scheme is proved to be secure in the random oracle model. Compared with the existing schemes, the proposed scheme has a short property certificate and signature size, and requires less computational cost. 展开更多

We propose a quantization procedure for the nucleon-scMar meson system, in which an arbitrary mean scalar meson field Ф is introduced. The equivalence of this procedure with the usual one is proven for any given value of qS. By use of this procedure, the scalar meson field in the Walecka's MFA and in Chin's RHA are quantized around the mean field, Its corrections on these theories are considered by perturbation up to the second order. The arbitrariness of Ф makes us free to fix it at any stage in the calculation. When we fix it in the way of Walecka's MFA, the quantum corrections are big, and the result does not converge. When we fix it in the way of Chin's RHA, the quantum correction is negligibly small, and the convergence is excellent. It shows that RHA covers the leading part of quantum field theory for nuclear systems and is an excellent zeroth order approximation for further quantum corrections, while the Walecka's MFA does not. We suggest to fix the parameter Ф at the end of the whole calculation by minimizing the total energy per-nucleon for the nuclear matter or the total energy for the finite nucleus, to make the quantized relativistic mean field theory (QRMFT) a variational method. 展开更多

Although its theoretical and methodological bases are in the initial stage of formulation. Though there are standards for regulating illumination quantitatively, the science has never created a bridge to transfer illumination quantity into illumination quality. How to keep a day image of architectural object without imitating natural lighting? How unrecognizably to change the image, to make it extraordinary and catchy? This paper offers a solution in the form of external illumination designing principles. This paper proposes two conceptual ways of creating artificial lighting of buildings and constructions that pursue different goals: the principle of "tectonic" illumination and the principle of "decorative" illumination. These principles were developed based on the analysis of the state of the art experience of lighting architectural objects and author's empirical study. The latter contained measuring luminosity with luminance meter, processing the data, statistical survey (180 respondents) and lighting modeling in the laboratory of Moscow Architectural Institute. 展开更多

Eosinophilic cholangiopathy is a rare condition characterized by eosinophilic infiltration of the biliary tract and causes sclerosing cholangitis. We report a patient with secondary sclerosing cholangitis with eosinophilic cholecystitis. A 46-year-old Japanese man was admitted to our hospital with jaundice. Computed tomography revealed dilatation of both the intrahepatic and extrahepatic bile ducts, diffuse thickening of the wall of the extrahepatic bile duct, and thickening of the gallbladder wall. Under the diagnosis of lower bile duct carcinoma, he underwent pyloruspreserving pancreatoduodenectomy and liver biopsy. On histopathological examination, conspicuous fibrosis was seen in the lower bile duct wall. In the gallbladder wall, marked eosinophilic infiltration was seen. Liver biopsy revealed mild portal fibrosis. He was diagnosed as definite eosinophilic cholecystitis with sclerosing cholangitis with unknown etiology. The possible etiology of sderosing cholangitis was consequent fibrosis from previous eosinophilic infiltration in the bile duct. The clinicopathological findings of our case and a literature review indicated that eosinophilic cholangiopathy could cause a condition mimicking primary sclerosing cholangitis (PSC). Bile duct wall thickening in patients with eosinophilic cholangitis might be due to fibrosis of the bile duct wall. Eosinophilic cholangiopathy might be confused as PSC with eosinophilia. 展开更多

The objective of this study was characterizing the gelatin from the chicken feet by FTIR (Fourier transform infrared) spectroscopy. Two gelatin samples were prepared for the experiment which were extracted of 200 g of chicken feet by a thermal bath of 4% acetyl acid solution at 60 ℃. A commercial gelatin was used to compare the results. FTIR spectra of gelatin samples were recorded using a Nicolet iS5 FTIR spectrometer equipped with an ATR/iD3 with argon horizontal cell in which the spectra were varied in the range of 400-4,000 cm1 at 16 ~C. The results showed that FTIR spectra of the chicken feet gelatin had the most with the vibration peak at wave numbers of 1,652.01 cm~ to the amide I, of 1,539.87 cm1 to the amide II, of 1,241.29 cm~ to the amide III, of 2,923.72 cm-~ to the amide B and of 3,399.56 cm~ to the amide A. The collagen composition of the chicken feet gelatins was twotimes larger than the commercial gelatin and the vibration bands to beef gelatin have been different from chicken feet gelatins. This demonstrates that chicken feet gelatins are very good nutritional quality when compared to the commercial gelatin. 展开更多

In 21st Century, Chinese and American universities are experiencing great development in the number of students studying abroad. This research adopts the method of natural investigation, selecting Chinese student samples during study abroad program in the University of Minnesota to complete the designed questionnaires to examine the intercultural interventions taken before, during and after this type of study abroad in Chinese universities. Also, after students complete the questionnaires, email communication is made to analyze the reasons for their answers to the questionnaires. The questionnaire results and email communication show that there is a great gap in the practice of intercultural interventions in study abroad programs between Chinese universities and students expectations. It is time for Chinese universities to design appropriate intercultural interventions in order to maximize Chinese university students' intercultural development during study abroad. These intercultural interventions should be run consistently to cover the phrases of pre-departure, during and after the study abroad program. Also, more dynamic and interactive intercultural interventions rather than knowledge-based intercultural instructions or guidance should be the focus for intercultural interventions. 展开更多

Three different nanorod-like gallium oxides with mono/poly-crystalline nature(α, β, and α/β-Ga2O3) were prepared by regulating the amount of polyethylene glycol(PEG) 6000 in the range of 0.2–0.8 g proportionally via a hydrothermal method combined with further calcination. The bandgap of the products, given by UV-Vis diffuse reflectance spectra(UV-Vis DRS), was in the order of α-Ga2O3 > α/β-Ga2O3 > β-Ga2O3. To further investigate the photocatalysis performance of the catalysts, the decomposition of rhodamine B(Rh B) by Ga2O3 under UV light illumination(λ < 387 nm) was presented and complete degradation could be achieved within 30 min, a result that showed the highest efficiency. The photocatalytic oxidation mechanism is further discussed and prominently related to the active species: hydroxyl radical(·OH) and superoxide radical(O·-2), which were confirmed by electron paramagnetic resonance(EPR). 展开更多

In order to promote the light output powers of GaN-based light emitting diodes (LEDs), two kinds of novel corrosive liquidshave been developed in this paper to roughen the surface of the indium tin oxide (ITO) current spreading layer of LEDs. As aresult, the textured transparent ITO layer greatly enhanced the external quantum efficiency of the LEDs. Provided that a wafersample was dipped in a kind of corrosive liquid developed by us for only about 60 s, the light output powers of the LEDs canbe promoted by 24.7%, compared with conventional GaN-based LEDs. It is obvious that the presented method is simple, rapidand cost-effective. 展开更多

A high performance heterojunction organic ultraviolet photodetector based on NPB and Bphen has been fabricated. A trans- parent conducting polymer PEDOT:PSS coated quartz substrate instead of ITO coated glass substrate as anode is propitious to detect shorter wavelength ultraviolet light. As a result, the device shows a low dark current density, a high responsivity of 502 mA/W and a detectivity of 2.67x1012 cm Hz1/Zfw which is illuminated by a 220 nm ultraviolet light with an intensity of 1.6 mW/cm2. Moreover, the performance of the PEDOT:PSS transparent electrode device is better than the semi-transparent A1 electrode device electrode because of the higher transmittance and electrode properties. 展开更多

A photochromic rhodamine B-based material containing Cd(Ⅱ) as bridge was facilely prepared. The 4-methoxylsalicylalde hyde rhodamine B bydrazone Cd(Ⅱ) complex displayed unusual ring-open response upon 365 nm UV irradiation, exhibiting long photochromic lifetime and good fatigue resistance. The UV-induced ring-open of the complex led to a distinct color and fluorescence change in acetonitrile. A new mechanism was put forward: salicylaldehyde part in the complex underwent UV-promoted isomerization from enol-form to keto-form, enhancing the chelation of Cd(Ⅱ) and yielding the ring-opening rhodamine B part. Compared to other reported photochromic systems, this new photochromic material offered attractive new insights into the development of low cost photochromic materials with good performance. 展开更多
