老年人与青年人价值观的相似性及其知觉准确度

目的探讨老年人与青年人价值观的相似性以及老年人与青年人对对方价值观的知觉准确度。方法运用价值观量表对576名老年人和青年人的价值观进行了调查。结果老年人与青年人价值观因素结构的整体相合系数为0.85,青年人对老年人价值观结构的知觉准确度略高于老年人但不明显,他们都能比较准确地知觉出对方的价值观,但所知觉的价值观差异远高于实际差异。结论老年人与青年人之间的相似性多于相异性,他们都能比较准确地了解对方,但却夸大了彼此之间的差异,提示应将着眼点放在老年人与青年人之间的共同点上以促进代际和谐。

Calculation of hydrogen solubility in molten alloys

A thermodynamic model was developed to calculate the hydrogen solubility in molten alloys based on the hydrogen solubility in constitutional pure liquid metals and their interaction parameters. The calculated results have a good agreement with the documented experimental results. The closer the molten alloy to an ideal liquid is, the more accurate the calculated results are. The compound forming ability and molar mixing heat of the constitutional elements take important roles in influencing the hydrogen solubility in molten alloys.

Edge detection in the potential field using the correlation coefficients of multidirectional standard deviations

Most edge-detection methods rely on calculating gradient derivatives of the potential field, a process that is easily affected by noise and is therefore of low stability. We propose a new edge-detection method named correlation coefficient of multidirectional standard deviations（CCMS） that is solely based on statistics. First, we prove the reliability of the proposed method using a single model and then a combination of models. The proposed method is evaluated by comparing the results with those obtained by other edge-detection methods. The CCMS method offers outstanding recognition, retains the sharpness of details, and has low sensitivity to noise. We also applied the CCMS method to Bouguer anomaly data of a potash deposit in Laos. The applicability of the CCMS method is shown by comparing the inferred tectonic framework to that inferred from remote sensing（RS） data.

Minimum variance adaptive beamforming combined with coherence factor weighting applied to ultrafast active cavitation imaging

The ultrafast active cavitation imaging(UACI)based on plane wave transmission and delay-and-sum(DAS)beamforming has been developed to monitor cavitation events with a high frame rate.However,DAS beamforming leads to images with limited resolution and contrast.In this paper,minimum variance(M V)adaptive beamforming and coherence factor(CF)weighting are combined to achieve an MVCF-based UACI,which can improve the cavitation imaging quality.The detailed algorithm evaluation has been investigated from both simulation and experimental data The simulation data include10point targets and a cyst,while the experimental data are obtained by detecting the dissipation of cavitation bubbles in water excited by a single element transducer with frequency of1.2MHz.The advantages of the proposed methodology as well as the comparison with conventional B-mode,DAS?M V,DAS-CF and MV on the basis of compressive sensing(CS)(called MVCS)beamformers are discussed.The results show that MVCF beamformer has a significant improvement in terms of both resolutions and signal-to-noise ratio(SN R).The MVCF-based UACI has a SNR at21.82dB higher,lateral and axial resolution at2.69times and1.93times?respectively,which were compared with those of B-mode active cavitation mapping.The MVCF-based UACI can be used to image the residual cavitation bubbles with a higher SNR and better spatial resolution

Coupling Between the Group—Related Coherent States

When two representations of the Lie algebra are coupled, the coupling integral kernels are presented to relate the coupled to uncoupled group-related coherent states. These kernels have a connection with usual coupling coefficients. The explicit expressions of these kernels for and are given. When the direct product of three representations is formed in two ways, the recoupling integral kernels relating to the coupled group-related coherent states corresponding to two different schemes are introduced, and the relations between these kernels and the general recoupling coefficients are obtained. The properties of these kernels are discussed.

Studies on genetic relationships among Oakleaf loquat, Daduhe loquat and common loquat by RAPD and ISSR

The genetic relationships among oakleaf loquat （Eriobotrya prinoides）, Daduhe loquat （Eriobotrya prinoides var. dadunensis） and common loquat （Eriobotrya japonica） were studied by RAPD and ISSR markers. The results showed that the similarity coefficient between oakleaf loquat and common loquat was minimal （0.6996 and 0.7219, respectively） and the similarity coefficient between oakleaf loquat and Daduhe loquat was maximal （0.8403 and 0.8211, respectively）, while the similarity coefficient between Daduhe loquat and common loquat was always intermediate （0.7195 and 0.7219, respectively）. The highest additivity was obtained when Daduhe loquat was regarded as the undetermined hybrid （44.9% and 45.8%, respectively）. The specific bands of oakleaf loquat and common loquat were present in Daduhe loquat. Thus, it could be concluded that Daduhe loquat was a hybrid of oakleaf loquat and common loquat.

Shadow detection combining characters of human vision

A shadow detection method using pulse couple neural network inspired by the characters of human visual system is proposed.More precisely,lateral inhibition of human vision and coefficient of variation are combined together to improve the pulse couple neural network.Shadow detection is considered to be a shadow region segmentation problem.Experiment shows that the presented method is consistent with human vision compared to shadow detection methods based on HSV and pulse couple neural network(PCNN) by both subjective and objective assessments.

Correlation between acne and Northwest dryness syndrome in Xinjiang autonomous region of China

OBJECTIVE： To analyze the correlation between ac- he and Northwest dryness syndrome in the Xinji- ang region to provide an epidemiological founda- tion for the prevention and treatment of acne in the region. METHODS： The correlations among acne, clinical syndromes of Northwest dryness syndrome, and Northwest dryness syndrome were evaluated using the syndrome fitness index and canonical correla- tion analysis. RESULTS： The ache group had a Northwest drynesssyndrome rate of 24.13%, and the control group 10.34% （χ2=7.733, P〈0.01）. There was no significant difference in the fitness index for acne and for the sub-syndromes of Northwest dryness syndrome （P〉 0.05）. The first canonical correlation coefficient was 0.5656 （P〈0.01）. The acne-dependent variable group had the largest damp-heat syndrome load （0.8709）, and the independent variable had the largest lung-heart-spleen pyretic dryness load （0.6766）. CONCLUSION： Northwest dryness syndrome is a risk factor for ache in the Xinjiang region. Exoge- nous dryness and endogenous damp are frequent- ly seen as subsyndromes in Northwest dryness syn- drome in acne patients in the region. Acne was cor- related with the damp-heat and lung-heart-spleen pyretic dryness sub-syndromes of Northwest dry- ness syndrome.
