An automatic three-dimensional(3D) reconstruction method based on four-view stereo vision using checkerboard pattern is presented. Mismatches easily exist in traditional binocular stereo matching due to the repeatable or similar features of binocular images. In order to reduce the probability of mismatching and improve the measure precision, a four-camera measurement system which can add extra matching constraints and offer multiple measurements is applied in this work. Moreover, a series of different checkerboard patterns are projected onto the object to obtain dense feature points and remove mismatched points. Finally, the 3D model is generated by performing Delaunay triangulation and texture mapping on the point cloud obtained by four-view matching. This method was tested on the 3D reconstruction of a terracotta soldier sculpture and the Buddhas in the Mogao Grottoes. Their point clouds without mismatched points were obtained and less processing time was consumed in most cases relative to binocular matching. These good reconstructed models show the effectiveness of the method.

In this work, zinc ferrite spinel with different zinc contents(ZnxFe_3-xO_4) was synthesized by a hydrothermal method and used for removing As(V) in aqueous solution. X-ray diffraction(XRD) results indicated that in the crystal structure of ZnxFe_3-xO_4, the zinc atoms tended to occupy the octahedral sites for x sites gradually with x > 0.6. The size of ZnxFe_3-xO_4 crystallites increased with the increasing zinc content. Batch adsorption experiments showed that the adsorption isotherms could be well described by the Langmuir model, while the adsorption kinetics followed the pseudo-second-order kinetic model. Zinc ferrite exhibited the highest adsorption capacity towards As(V) when x = 0.6. Study of the mechanism indicated that doping with zinc increased the number of surface hydroxyl groups on ferrite spinel, and thus enhanced the adsorption capacity when x = 0.6. This work revealed the effects of doping site and content of metal atoms on the adsorption ability of ferrite spinel towards As(V).

A modified apical dissection of the prostate to improve the efficiency of vesico-urethral anastomosis （VUA） in laparoscopic radical prostatectomy （LRP） was reported. A total of 42 patients were randomly selected and enrolled in this study. A standard LRP was performed in 21 patients （group 1）, whereas a novel, modified apical dissection of the prostate in LRP was performed in another 21 patients （group 2）. Surgical data, total operative time, VUA time, extravasation rate, catheterisation time, occurrence of anastomotic strictures, and the early and late continence rates were analysed statistically. No differences in clinical or pathological characteristics were determined between the two groups. The total operative time, VUA time, blood loss and catheterisation time were lower in group 2, which received the novel, modified technique compared with group 1, which received the standard technique to dissect the apex of the prostate （P〈0.01 for each variable）. Regarding the extravasation rate and the occurrence of anastomotic strictures, no significant differences were found between the two groups （P〉0.0.05 for each）. After catheter removal, a statistically significant difference in the continence rates was present at 3 and 30 days post operation in the two groups （P〈0.01, respectively）. At 90 days post operation, the difference, although still present, was no longer statistically significant （P〉0.05）. The novel, modified apical dissection of the prostate facilitates the VUA and significantly improves the efficacy of the procedure and early restoration of continence.

The structure of the state-vector space of identical bosons in noncommutative spaces is investigated. To maintain Bose-Einstein statistics the commutation relations of phase space variables should simultaneously include coordinate-coordinate non-commutativity and momentum-momentum non-commutativity, which leads to a kind of deformed Heisenberg-Weyl algebra. Although there is no ordinary number representation in this state-vector space, several set of orthogonal and complete state-vectors can be derived which are common eigenvectors of corresponding pairs of commuting Hermitian operators. As a simple application of this state-vector space, an explicit form of two-dimensional canonical coherent state is constructed and its properties are discussed.

Background： Dorper is an important breed for meat purpose and widely used in the livestock industry of the ***, the protein requirement of Dorper crossbred has not been investigated. The current paper reports the net protein（NP） and metabolizable protein（MP） requirements of Dorper crossbred ram lambs from 20 to 35 kg ***： Thirty-five Dorper × thin-tailed Han crossbred lambs weaned at approximately 50 d of age（20.3 ± 2.15 kg of BW） were used. Seven lambs of 25 kg BW were slaughtered as the baseline animals at the start of the trial. An intermediate group of seven randomly selected lambs fed ad libitum was slaughtered at 28.6 kg BW. The remaining 21 lambs were randomly divided into three levels of dry matter intake： ad libitum or 70% or 40% of ad libitum intake. Those lambs were slaughtered when the lambs fed ad libitum reached 35 kg BW. Total body N and N retention were ***： The daily NP and MP requirements for maintenance were 1.89 and 4.52 g/kg metabolic shrunk BW（SBW0.75）.The partial efficiency of MP utilization for maintenance was 0.42. The NP requirement for growth ranged from 12.1 to 43.5 g/d, for the lambs gaining 100 to 350 g/d, and the partial efficiency of MP utilization for growth was ***： The NP and MP requirements for the maintenance and growth of Dorper crossbred male lambs were lower than the recommendations of American and British nutritional systems.
