The objective of this study was to systematically assess the changes of production performance, meat quality, immune and antioxidant properties of Qianbei Ma goat under different feeding method, so as to provide scientific support for high-yield, high-quality and healthy mutton production. Twenty six healthy Qianbei Ma goat rams with similar body weight [(19.68±1.60) kg] were randomly and averagely divided into grazing and stallfeeding groups. The grazing group was fed with traditional grazing, and the stall-feeding group was fed with full price pellet feed. The pre test period was 10 days, and the trial period was 180 days. After the test, three goat in each group were slaughtered to compare the production performance, meat quality, immunity and antioxidant performance of the two groups. The results showed that: ① in terms of production performance, compared with the grazing group, the stall-feeding group had better production performance in terms of final body weight, average daily gain, carcass weight, slaughter rate, net meat weight, meat to bone ratio, shearing force, cooked meat rate, but the skin was thinner, loin eye area was smaller, bone was lighter, pH was higher, with a significant difference in meat to bone ratio (P<0.05). ② In terms of meat nutrient composition, the contents of glycine, tyrosine and proline in the 16 kinds of amino acids in the stall-feeding and grazing groups were significantly different (P<0.05), while the contents of other 13 kinds of amino acids and total amino acids had no significant difference; The contents of protein, fat and cholesterol in the grazing group were higher than those in the stall-feeding group, but there was no difference between the two groups. ③ In terms of immune and antioxidant properties, immune indicators of the stall-feeding group γ interferon was higher than that in grazing group (P<0.05), lysozyme was lower than that in grazing group (P<0.05), and there was no significant difference between MDA and four antioxidant indexes (P>0.05). In conclusion, the meat carrying capacity of Qianbei Ma goat is stronger in stall-feeding than in grazing. The feeding regimens has a small impact on meat quality and antioxidant performance. However, the immune regulation ability of grazing feeding is better, and it is suggested that a suitable indoor (outside) sports field should be equipped in stall-feeding, which can improve the meat production capacity while protecting the immunity and health of the goat.

The tumor volumes of mice in the high-dose and low-dose groups were significantly lower than that of the control group at the 6th to 21st day of administration, with statistically significant differences (P<0. 05), of which the tumor volumes of mice in the highdose group were the smallest. The mean tumor weights of the high-dose group and low-dose group on the 22nd day were respectively (0. 343±0. 089) g and (0. 658±0. 145) g, which were significantly lower than that of the control group[(1. 163±0. 231) g], with statistically significant differences(P<0. 05). The tumor inhibition rates of the highdose group and low-dose group were respectively 64. 46% and 34. 07%, and there was a dose dependence. The expression levels of ERK1 / 2 and p-ERK1 / 2 in mice in the high-dose group and low-dose group were significantly lower than those in the control group, with statistically significant difference (P<0. 05), of which the expression levels of ERK1 / 2 and p-ERK1 / 2 in mice in the high-dose group were the lowest. CONCLUSIONS: Apatinib can effectively inhibit the ERK1 / 2 signaling pathway in breast cancer cell, induce apoptosis and proliferation of tumor cells, and thus inhibit the growth of tumors in breast cancer mice.

Focusing on the problem that the traditional tracking method is susceptible to occlusion of similar objects, this paper proposed a similarity matching tracking method which based on weighted model. According to weighted theory, it divided the target region into local feature blocks, assigned different weights to them, therefore it established the local weighted model of target. Then it used the target color and location characteristics to calculate the similarity between the test images and the target model. In order to avoid the interference of complex background, the method divided the foreground area before model matching, which could get more accurate matching results. Finally, it proposed a novel method of updating occlusion decision model, which ensured the robustness of the model matching by judging the serious occlusion of the target. The experimental results show that the proposed method can achieve high tracking accuracy by using weighted model and multi-feature similarity matching. And the average center error ( ACE) of this tracker is only 13. 21. The overlap rate is 0. 71. [ABSTRACT FROM AUTHOR]

This paper proposed an efficient LFA implementation method based on incremental shortest path first algorithm ( ERPISPF) to reduce the computational overhead and deployment difficulty of the existing LFA algorithm. The paper first turned the problem of quick implementation of LF A into how to efficiently calculate the minimum cost of all its neighbors to all other nodes of the network on the shortest path tree rooted at the compute node. Then it presented a theorem for calculating the cost and proved its correctness. Finally, it theoretically analyzed the time complexity of the algorithm. Experiments show that compared with LFA algorithm, ERPISPF not only has less computation overhead, but also provides the same failure protection rate as LFA. [ABSTRACT FROM AUTHOR]

In terms of the uneven removal and substandard flatness on the workpiece’s surface in disc grinding,a calculation method with multiple grits’ removal rate was proposed. Firstly,a mathematic model for the disc wheel’s grits’ distribution was established considering the grits’ sizes and the positions. Then,the multiple grits’ dynamic trajectory equation was deduced.Meanwhile,the workpiece’s removal rate model was established on this basis. The rationality of the model was further validated by the experiment of disc grinding. The results show that the removal effect appears to be uneven on the workpieces’ surfaces of disc grinding. It is the lower removal rate that leads to the embossment phenomenon in the central location. Moreover,the height difference of ground workpieces’ surface profile goes up with the increase of the speed ratio. Therefore,it is advisable to reduce the speed ratio so as to improve the consistency of the ground workpieces’ surface. [ABSTRACT FROM AUTHOR]

Aiming at the drawbacks of the traditional methods which cannot make the constructed depth models meet the requirement of navigational safety, a method for constructing digital depth model(DDM) serving for navigation using pre-constructed model surface to control and adjust the selection of DDM nodes is proposed. Firstly, the selected depths, the alternative depths, the candidate depth and the pre-constructed model surface are defined. Secondly, the probability and the representativeness of DDM are calculated quantitatively by using the alternative depths so that the model quality can be estimated dynamically in the process of the depth modeling. Finally, the operator for selecting depths is designed and utilized for controlling and adjusting the selection of the depths quantitatively, thus the models are constructed of which the probability of an adequate depth meets the requirement of the navigational safety. The experimental results demonstrate that: (1) compared with the traditional method, the proposed method can make the probability of the depth model meet the requirement of navigational safety; (2) for the depths of which the assuring rate meet the requirement of the navigational safety, the representativeness of the depth model constructed with the proposed method is higher than that of the traditional method.

For the high complexity problem of edit distance calculation in the similarity confirmation step, a string similarity confirmation algorithm based on pigonhole principle under the limitation of edit distance is proposed. Firstly, it found a segment satisfies the edit distance segment mapping, then based on this segment, the read length of 500 bp was segmented. Then the edit distance of right and left parts was calculated and all parts sum to the final result. Finally, based on the longest common substring, the number of segments to be verified is minimized, and an optimization scheme was obtained. The experimental result show that this verification algorithm reduces the time of the verification step, and ensures the zero false positive and false negative rate. [ABSTRACT FROM AUTHOR]

The traditional three-node cooperative communication model is simple and feasible, but in the two-stage cooperative transmission process, relay nodes usually help source nodes forward data for free. It reduces the efficient spectrum utilization when the links are of different qualities. Based on the decode-and-forward (DF) cooperative protocol, this paper proposed a new cooperative forwarding scheme. It could improve the transmission rate of the system by using superposition coding. The scheme used the CSI to process the relay selection and power optimal allocation. In collaboration, relay nodes transmitted their own data by superposition coding while forwarding the data of source nodes. By flexibly adjusting the power allocation during superposition coding, the proposed transmission scheme could guarantee the transmission rate of the system. Simulation results show that the proposed scheme can effectively improve the transmission rate of the system. [ABSTRACT FROM AUTHOR]
