Surface plasmon microscopy (SPRM) usually employs high refractive index prism or high numerical aperture (NA) objective as coupling device to excite surface plasmon. Here we apply high NA oil-immersion objective considering k vector conditions of SPs and localization of SPs which provides better lateral resolution and less cross-talk between adjacent areas. However, performance of an objective based SPRM is often limited by the finite aperture of a physical objective which corresponds to sudden transition and limited bandwidth. Here we give a simplified model of the SPRM and numerically calculate how the sudden transition on the clear aperture edge causes inherent error. Notch filtering algorithm is designed to suppress the noisy ripples. Compared to the pupil function engineering technique, this technique makes both the sacrifice of NA and utilization of spatial light modulator unnecessary and provides a more compact system setup without decreasing the resolution and contrast. © 2016 SPIE.

In this paper, we discuss the influence analysis of ridge estimate of parameter in the restricted linear regression models. For the proposed conditional ridge estimate, two cases of influence with disturbance of covariance matrix or data deleting are studied, and the relevant conclusions are established. Furthermore, the definition of the generalized Cook distance and the Welsch-Kuh statistic are given to assess the extent of influence and a numerical example is given to show their effectiveness. © 2010 Binary Information Press.

The airlift external circulation membrane bioreactor (AEC-MBR) is a new MBR consisting of a separated aeration tank and membrane tank with circulating pipes fixed between the two tanks. The circulating pipe is called a H circulating pipe (HCP) because of its shape. With the complex configuration, it was difficult but necessary to master the AEC-MBR's hydraulic characteristics. In this paper, simulation and optimization of the AEC-MBR was performed using computational fluid dynamics. The distance from diffusers to membrane modules, i.e. the height of gas-liquid mixing zone (hm), and its effect on velocity distribution at membrane surfaces were studied. Additionally, the role of HCP and the effect of HCP's diameter on circulation were simulated and analyzed. The results showed that non-uniformity of cross-flow velocity existed in the flat-plate membrane modules, and the problem could be alleviated by increasing hm to an optimum range (hm/B ≥ 0.55; B is total static depth). Also, the low velocity in the boundary layer on the membrane surface was another reason for membrane fouling. The results also suggested that HCP was necessary and it had an optimum diameter to make circulation effective in the AEC-MBR. © IWA Publishing 2014.

The hybrid films of reinforcing the aged papers have been employed via layer-by-layer (LBL) assembly deposition of the chitosan lactate/carboxymethyl cellulose complex previously modified with metal oxide. In order to reinforce the films, a vacuum infiltration was adopted in the LBL process. The mechanical properties and structure of the aged papers in relation to fiber morphology were investigated using SEM, FTIR, XPS, and tensile test. The well-dispersed coatings resulted in an excellent improvement in mechanical properties of the modified paper. After only three bilayers deposited, the measured tensile strength and folding endurance for modified aged newspaper samples increased up to 100% and 450%, respectively, as compared to the control sample. This high efficiency was kept even when the modified paper samples exposed to the moist-heat accelerated aging and UV irradiation. The pH of the paper rose to alkalescence rapidly, and the paper samples maintained their coloration close to the original after treatment. © 2016 American Chemical Society.

This paper presents a reference framework, called BUD, to manage a large shared bank of unstructured data. This paper lists several important issues on managing or maintaining the unstructured data in BUD. BUD stores and manages the ever-growing unstructured data by introducing a novel technique called free-table, which is a conceptual view for endusers and a physical entity maintained by transactional storage manager of BUD. Free-table is cell-oriented but not columnoriented as relational table. It can store various types of unstructured data in cell with different versions. Additionally, we study two cases, VMP and PXRDB, to show that our proposal is feasible and tractable. © 2010 IEEE.

Purpose-The purpose of this paper is to present an econometric model to empirically analyze the influence of production patterns and transaction style on raw milk quality. More specifically, the paper examines the effects of these institutions on both nutrition and safety aspects of raw milk quality. Design/methodology/approach-Using data collected from 396 households in Inner Mongolia, this paper adopts a multiple linear regression model (OLS/FGLS) and a zero-inflated Poisson regression model to test two hypotheses proposed according to theory and descriptive analysis. Findings-The empirical results indicate that both production pattern and transaction style significantly affect raw milk quality. Production pattern has a more significant effect on raw milk nutrition, while transaction style has a more significant effect on raw milk safety. Research limitations/implications-Current government policies focus on reducing household production and regulating private milk collection stations. From a comprehensive quality perspective, these policies are not effective in that they cannot guarantee raw milk safety and have little effect on improving raw milk nutrition. Alternatively, promoting dairy farmers' specialized cooperatives may be a more effective policy measure. Originality/value-In contrast to other studies, this paper adopts a comprehensive quality perspective that examines both nutritional and safety characteristics rather than focusing on any single quality indicator, separately analyzing the factors influencing raw milk nutrition and raw milk safety. Therefore, the conclusion of this paper provides a new perspective in addressing the current raw milk quality problems facing China's dairy industry. © 2013 Emerald Group Publishing Limited.
