In this paper, we present an interactive method for blending point-based geometries by dragging-and- dropping one point-based model onto another model’s surface metaphor. We first calculate a blending region based on the polygon of interest when the user drags-and-drops the model. Radial basis function is used to construct an implicit surface which smoothly interpolates with the transition regions. Continuing the drag-and-drop operation will make the system recalculate the blending regions and reconstruct the transition regions. The drag-and-drop operation can be compound in a constructive solid geometry (CSG) manner to interactively construct a complex point-based model from multiple simple ones. Experimental results showed that our method generates good quality transition regions between two raw point clouds and can effectively reduce the rate of overlapping during the blending.展开更多

It is comprised of 1 550 bp and an open reading frame （ORF） of 241 amino acids, with a predicted molecular mass of approximately 28 kDa. In situ hybridization histochemistry revealed a tissue-specific expression pattern of Amphi-PhLP with the high levels in the ovary, and at a lower level in the hind grit and testis, hepatic caecum, gill, endostyle, and epipbaryngeal groove, while it was absent in the muscle, neural tube and notochord. In the Chinese Hamster Ovary （CHO） cells transfected with the expression plasmid pEGFP-NI/Amphi-PhLP, the fusion protein was targeted in the cytoplasm of CHO cells, suggesting that Amphi-PhLP is a cytosolic protein. This work may provide a framework for further understanding of the physiological function of Amphi-PhLP in B. belcheri.展开更多

The patient underwent tongue tumor resection and left forearm radial skin flap repair, and then received 50 Gy 3-D conformal radiotherapy and chemotherapy combining 5-fluorouracil with carboplatin. One year after the operation, although the patient showed no tumor recurrence in primary site and no metastasis of cervical lymph nodes, metastasis occurred in several tissues including spine, ribs, mandible, skeletal muscles of upper extremity as well as lymph nodes of the mediastinum and lung hilum, which caused the patient to die quickly. According to the literature, we conclude that distant metastasis of tongue squamous cell carcinoma was less common, but once it occurs, the prognosis of the patient is extremely poor.展开更多

As Irradiation facility for research the goal of this paper is to show a case study of application of nuclear security and nuclear security culture code of contact in irradiation facility using cobalt 60. And it will show the necessary work done to achieve the goal of protection of radioactive material and continue working in safe conditions. This objective could not be achieved without the collaboration of all department involved in security and nuclear safety. In this work we applied the nuclear security and nuclear security culture procedures in order to define the type of system used to achieve the global objective in accordance with Global Threat Reduction Program to reduce the threat of a RDD （Radiological Dispersion Device） in collaboration with The United States Department of Energy＇s NNSA （National Nuclear Security Administration）. The objective of this paper is to share a local experience in upgrading security with return of experience in practice and very good collaboration with general direction of national security and all departments involved in security and nuclear safety.展开更多

Worldwide research on intercultural communication is the rise of a new field of study in recent 30 years. With the deepening of reform and opening up, China＇ s exchanges with the world are more and more frequent, China approaches to the world, and the world is also approaching the China. China should learn from the advanced experience of foreign countries, to learn all the outstanding achievements of human civilization all over the world, while the splendid Chinese culture will also be introduced to the world.

Researchers＇ performance is necessary to be understood by analyzing researchers＇ paper outcome. To drive successful outcomes and co-research, researchers＇ paper outcome should be autonomously established. Therefore we propose an approach to manage and update easily paper outcome of researchers. The proposed approach makes researchers search their paper using the Google Scholar＇s opened API （application program interface） and update their outcome. Since researchers autonomously can establish the list of their own papers in our service using open service, researchers＇ personal outcome can be efficiently managed.展开更多

To reveal whether these two activities can modify the hydrological cycle and climate system in China, we conducted two sets of numerical experiments using regional climate model RegCM4. In the first experiment used to study the climatic responses to human carbon emissions, the model were configured over entire China because the impacts of carbon emissions can be detected across the whole country. Results from the first experiment revealed that near-surface air temperature may significantly increase from 2007 to 2059 at a rate exceeding 0.1 ~C per decade in most areas across the country; southwestern and southeastern China also showed increasing trends in summer precipitation, with rates exceeding 10 mm per decade over the same period. In summer, only northern China showed an increasing trend of evapotranspiration, with increase rates ranging from 1 to 5 mm per decade; in winter, increase rates ranging from 1 to 5 mm per decade were observed in most regions. These effects are believed to be caused by global warming from human carbon emissions. In the second experiment used to study the effects of human water use, the model were configured over a limited region-- Haihe River Basin in the northern China, because compared with the human carbon emissions, the effects of human water use are much more local and regional, and the Haihe River Basin is the most typical region in China that suffers from both intensive human groundwater exploitation and surface water diversion. We incorporated a scheme of human water regulation into RegCM4 and conducted the second experiment. Model outputs showed that the groundwater table severely declined by -10 m in 1971-2000 through human groundwater over- exploitation in the basin; in fact, current conditions are so extreme that even reducing the pumping rate by half cannot eliminate the ground- water depletion cones observed in the area. Other hydrological and climatic elements, such as soil moisture, runoff generation, air humidity, precipitation, wind field, and soil and air temperature, were also significantly affected by anthropogenic water withdrawal and consumption, although these effects could be mitigated by reducing the amount of water drawn for extraction and application.展开更多

First, it explores the historical inroads made by the colonizer in West African countries, such as Ghana, causing the debilitation of the culture of such countries by erasing its history. One way in which such erasure occurred was in the destruction of sacred sites of the people. Further connections will also be made to West African cultural contexts with the history of colonization in Africa and its effects on popular culture, specifically drama in countries like Ghana. Next, the essay draws upon the role of the trickster figure of Ananse, the spider who features in many West African and Caribbean folkloric traditions. Sutherland＇s play revolves around the main character of the play, Ananse, and he is likened to the trickster figure, but the essay shows how this figure is also debilitated by the colonizer. Finally, in the play, one notes that despite the main character＇s ＂victory＂ in getting his daughter married to the ＂Chief-Who-ls-Chief＇, he does it for his survival and the survival of his daughter in a world in which the latent effects of colonization has hampered the memory and culture of its people.展开更多

The material removal is based on two phenomena： electrochemical dissolution of the material and thermal erosion of electrical discharges that occur between the cathode ＆ anode electrodes. This process is better used for machining of non conducting materials efficiently. In this research paper shows that a brief literature review study of various measuring instruments used for analysis of various parameters of the electrochemical discharge machining process on various types of materials, tool material, input ＆ output parameters such as surface roughness, surface texture, material removal, tool wear etc..展开更多
