INTRODUCTION Changbai Mountain is situated between E127°54′-128°08′, N40°58′-42°06′ about 2700 meters above sea level. It is the typical area of the mountainous climate in the monsoon area of the temperate zone on the globe. The well reserved primeval vertical distribution of natural landscape belts and the Natural Conservation of Changbai Mountains adopted by the UNESCO′s MAB Program cause the worldwide attention of geographers. Beside the complexity of the climatic structure itself, the mechanical effection of the high mountain body also effect the climate in the eastern part of China. In the mountain area where short of meteorological observation data, the climatic study by remote sensing is favorable for discovery and representation of climatic law in large area.展开更多

I do believe that there comes a time when there is lack of a reversible interaction between the soul and the spirit in certain individuals which leads to a state of mental offset. For humans to live in sociality the world is governed by humans’ laws but the mentally offset human do not live according to these laws. Due to this, they are considered as being useless in the society but I do believe that they have complete natural human rights and are not useless for they are aware of each act they perform.

The objective of this study was to examine the relationship between participation in mind-body-spirit (MBS) therapeutic programs and length of stay in a residential treatment facility. A retrospective analysis of data from 1719 subjects who were admitted to a 30-day residential program for substance use disorders (SUD) was conducted. Subjects participated in MBS programs that included yoga, acupuncture and meditation. We examined the effects of subject participation in MBS programs for subjects who left against staff advice (ASA) and those who successfully completed the residential program. A higher percentage of subjects with severe heroin use disorder left ASA compared with subjects with severe alcohol use disorder (16% vs. 9%, respectively). Most subjects from both substance groups who failed to complete the 30-day treatment program, left within the first two weeks of stay (59% of alcohol group and 75% of heroin group);however, again, the percentage of heroin users leaving during the first two weeks was significantly greater compared with that of alcohol subjects. We found a highly significant, positive correlation (r = 0.56, p < 0.01) and a statistically significant increase in LOS for all subjects, regardless of the substance type, and the number of MBS program sessions attended showing an association between MBS participation and increased LOS. These data support the inclusion of MBS programs as part of a comprehensive treatment strategy for SUD in combination with traditional counseling to help develop a sustainable long-term recovery.展开更多

This work discusses a more efficient model of the relative motion dynamics of satellites formation. The model is based on employing the concepts restricted three-body problem (R3BP) and for more accuracy, it considers the effects of both oblateness and radiation pressure on deputy relative motion w.r.t the chief satellite. A model of deputy relative motion w.r.t the chief satellite is derived in the local-vertical local-horizontal system and simplified assuming the concept of the circular restricted three-body problem (CR3BP). The deputy equations of motion were rewritten in the form of recurrence relations and solved numerically using the Lie series approach. Assuming that the formation is revolving around the Moon in the Earth-Moon system, the effects of both oblateness and radiation pressure on the deputy satellite orbit were assessed through a particular example of satellites formation. A comparison between the perturbed and unperturbed R3BP shows a significant difference in the deputy relative position that has to be considered for the formation dynamics.展开更多

In the coupled governing equations of linear thermoelastic media, the influences of thermo-osmosis effect and thermal filtration effect were introduced.

The influences of the differences between the properties of the two layers (e.g., the coefficient of thermal consolidation, elastic modulus) on thermal consolidation were discussed. The studies show that the coupling effects of displacement and stress fields on temperature field can be completely neglected, however, the the thermal responses. effect has an obvious influence on展开更多

For urban core areas in China, in which the metro was built later, there was more consideration for meeting the traffic needs of cities. However, there are few studies of collaborative planning for metro stations and their surrounding space. Thus, there is an urgent need to conduct research on collaborative planning for metro stations and their surrounding commercial space in urban core areas. Unlike conventional methods of integrated design of stations and cities, this paper, based on the theory of place spirit, took Chunxi Road Metro Station in Chengdu and its surrounding commercial space for example. It explored the pattern and characteristics of the place in the commercial space around the metro station, analyzed the strategies of cultural and commercial integration, as well as architecture, street, landscape and other aspects of the design method in the space, and explored the strategies of place-making and infiltration, providing a reference point for the development and place-making of the commercial space around metro stations in urban core areas.展开更多

We constructed three different types, namely, one-step (cubic and quintic Hermite), two-step, and three-step Hermite interpolation schemes. The continuous approximations obtained by Hermite interpolation schemes and interpolants for ODEX2 and ERKN integrators are discussed in this paper. The primary focus of this paper is to measure the accuracy and computational cost of different types of interpolation schemes for a variety of gravitational problems. The gravitational problems consist of Kepler’s two-body problem and the more realistic problem involving the Sun and four gas-giants—Jupiter, Saturn, Uranus, and Neptune. The numerical experiments are performed for the different integrators together with one-step, two-step, and three-step Hermite interpolation schemes, as well as the interpolants.展开更多

We constructed three different types, namely, one-step (cubic and quintic Hermite), two-step, and three-step Hermite interpolation schemes. The continuous approximations obtained by Hermite interpolation schemes and interpolants for ODEX2 and ERKN integrators are discussed in this paper. The primary focus of this paper is to measure the accuracy and computational cost of different types of interpolation schemes for a variety of gravitational problems. The gravitational problems consist of Kepler’s two-body problem and the more realistic problem involving the Sun and four gas-giants—Jupiter, Saturn, Uranus, and Neptune. The numerical experiments are performed for the different integrators together with one-step, two-step, and three-step Hermite interpolation schemes, as well as the interpolants.
文摘Based on the continuum hyperspherical harmonics expansion momentum rep-resentation transformation(CHHE-MRT)method,a new approach is proposed to cal-culate the matrix elements of any forms of potential.By introducing the modifiedCHHE-MRT function,the 3N dimensional Bessel oscillatory integral appearing in po-tential calculation can be reduced to 3M dimension(N≥M).The method presentedhere can be used not only for bound stute but also for scattering state in few-body sys-tem.
