Mn-doped ZnO nanorod arrays (ZnO:Mn NAs) have been prepared by a solution deposition method and the effect of Mn modification has been studied. Microstructure, morphology, photoluminescence characteristics of the ZnO: Mn NAs were investigated using X-ray diffraction, field emission scanning electron microscopy, fourier transform infrared spectrometer, fluorescence spectrophotometer. XRD analysis shows that ZnO:Mn NAs are wurtzite phases and highly c-axis oriented. As for ZnO:Mn NAs, obvious changes of photoluminescence intensity are observed at the wavelength of 395nm and 550 nm, according to Mn/Zn atomic ratio. Source

This paper aims to accurately obtain connecting plate outline. First, a camera captured a connecting plate image, then transmitted it to a computer, next converted it to a gray image, after that used Canny operator to extracted its edge information, and converted the pixel points of the gray image to rectangular coordinate values, at last found out all of the vertices of the connecting plate. Research result shows that the system is simple, its accuracy is less than 0.3%, and the data processing is convenience. © (2011) Trans Tech Publications, Switzerland. Source

A blind subspace code-aided technique for suppression of narrowband interference (NBI) and multiple access interference (MAI) in code division multiple access (CDMA) networks is proposed. This technique is based on the minimum mean output energy (MMOE) algorithm to improve the performance of direct matrix inverse (DMI) code-aided technique. Specifically, the performance of this technique against the type of NBI, namely, quasi-deterministic signals including sinusoidal tones and data NBI is analyzed. In this paper, signal to noise and interference rate (SINR) performance against NBI and MAI is addressed and then compared with DMI code-aided technique. It is seen that this method outperforms current DMI code-aided technique. © 2011 IEEE. Source

A blind adaptive subspace code-aided technique for suppression of narrowband interference (NBI) and multiple access interference (MAI) in code division multiple access (CDMA) networks is proposed. This technique is based on projection approximation subspace tracking with deflation (PASTd) algorithm to improve the performance of recursive least square (RLS) algorithm based on direct matrix inverse (DMI) code-aided technique. Specifically, the performance of this technique against the type of NBI, namely, quasi-deterministic signals including sinusoidal tones and data NBI is analyzed. In this paper, signal to noise and interference rate (SINR) performance against NBI and MAI is compared with DMI RLS algorithm. It is seen that this method outperforms current DMI RLS technique. © 2011 IEEE. Source

Recent Patents on Inflammation and Allergy Drug Discovery | Year: 2010

The prevalence of allergic diseases has increased dramatically in recent decades. Holding patens is one of the means to protect good anti-allergy products. However, little is known of anti-allergy patent situation in China. The paper summarized and analyzed anti-allergy patents issued in China from January 1988 to September 2008. A total of 789 anti- allergy patents have been granted in China during the 20 years. China, European countries, USA, Japan and other countries possesses 44%, 21%, 19%, 12% and 4% of all of these anti-allergy patents respectively. Interestingly, 88% anti- allergy patents issued to Chinese are held by civilians, whereas vast majority of the patents issued to foreigners were held by pharmaceutical companies. All anti-allergy patents are focused on synthetic compounds, Traditional Chinese medicines (TCM), combinations of synthetic compounds and TCM (CST), biological products and medical apparatus. The anti-allergy patents in China mainly focus on well-known targets, such as histamine receptor and leukotrienes, which consist of 93% of patents for validated targets. Approximately 93% targeting diseases are bronchial asthma, allergic rhinitis and atopic dermatitis. Our analyzing results indicate that there are great opportunities for application of patents on development of novel anti-allergic compounds and modernization of TCM in China. © 2010 Bentham Science Publishers Ltd.
