Efficient spin-current injection in single-molecule magnet junctions

We study theoretically spin transport through a single-molecule magnet (SMM) in the sequential and cotunneling regimes, where the SMM is weakly coupled to one ferromagnetic and one normalmetallic leads. By a master-equation approach, it is found that the spin polarization injected from the ferromagnetic lead is amplified and highly polarized spin-current can be generated, due to the exchange coupling between the transport electron and the anisotropic spin of the SMM. Moreover, the spin-current polarization can be tuned by the gate or bias voltage, and thus an efficient spin injection device based on the SMM is proposed in molecular spintronics.Comment: 4 figure

Deep Spatial Feature Reconstruction for Partial Person Re-identification: Alignment-Free Approach

Partial person re-identification (re-id) is a challenging problem, where only several partial observations (images) of people are available for matching. However, few studies have provided flexible solutions to identifying a person in an image containing arbitrary part of the body. In this paper, we propose a fast and accurate matching method to address this problem. The proposed method leverages Fully Convolutional Network (FCN) to generate fix-sized spatial feature maps such that pixel-level features are consistent. To match a pair of person images of different sizes, a novel method called Deep Spatial feature Reconstruction (DSR) is further developed to avoid explicit alignment. Specifically, DSR exploits the reconstructing error from popular dictionary learning models to calculate the similarity between different spatial feature maps. In that way, we expect that the proposed FCN can decrease the similarity of coupled images from different persons and increase that from the same person. Experimental results on two partial person datasets demonstrate the efficiency and effectiveness of the proposed method in comparison with several state-of-the-art partial person re-id approaches. Additionally, DSR achieves competitive results on a benchmark person dataset Market1501 with 83.58\% Rank-1 accuracy.Comment: 8 pages, 11 figures, accepted by CVPR 201

Analysis of sugar content in formula foods and complementary foods for infants and young children aged 0-36 months in China

ObjectiveTo investigate the implementation of the standards （formula foods and complementary foods for infants and young children）， the contents of glucose， galactose， fructose， lactose， sucrose and maltose in formula foods and complementary foods for infants aged 0-36 months， and provide data support for the management of food safety standards related to infant formula and infant complementary food in China.MethodsBased on the principle of random sampling， 83 formula food and complementary food for infants and young children， including infant formula foods， older infant formula foods， young children formula foods， cereal complementary foods and canned foods for infants and young children， were collected from the domestic market， the content of glucose， galactose， fructose， lactose， sucrose and maltose were determined by ion chromatography-pulse ampere method and the results were analyzed.ResultsThe median of total sugar content in formula foods for infants and young children was 433.43-476.99 g/kg； the proportion of lactose in all kinds of products was higher than 95%， and the content from high to low was infant formula， older infant formula and formula for young children. The detection rate of sugar in infant cereal supplementary food was 36.8%， the median content was 0-28.35 g/kg； the medians of lactose and sucrose were 84.30 and 70.17 g/kg； while the third quartile（Q3） of sucrose was 53.43 g/kg. There was no significant difference in the content of added sugar between domestic and imported formula foods（P>0.05）.ConclusionThe lactose content in formula foods for infants and young children sold in China is higher than that of other sugars. The content of total sugar in cereal supplementary food is low， but the content of sucrose in biscuit should be concerned. It is suggested that enterprises should strictly control added sugar， and government departments should continue to push the implementation of the sugar content regulation in the newly released national standards

Efficacy and safety of the compound Chinese medicine SaiLuoTong in vascular dementia: A randomized clinical trial

Introduction: No licensed medications are available to treat vascular dementia (VaD). Methods: Patients were randomly assigned to experimental groups (SaiLuoTong [SLT] 360 or 240 mg for groups A and B for 52 weeks, respectively) or placebo group (SLT 360 mg and 240 mg for group C only from weeks 27 to 52, respectively). Results: Three hundred twenty-five patients were included in final analysis. At week 26, the difference in VaD Assessment Scale-cognitive subscale scores was 2.67 (95% confidence interval, 1.54 to 3.81) for groups A versus C, and 2.48 (1.34 to 3.62) for groups B versus C (both Discussion: This study suggests that SLT is effective for treatment of VaD, and this compound Chinese medicine may represent a better choice to treat VaD
