Multi-sided surfaces are important in several areas of Computer-Aided Geometric Design, including curve network based design, approximation of triangular meshes, hole filling, and so on. In the majority of surface representations, the boundary constraints entirely determine the interior of these patches, however, frequently there is a need to have additional design freedom for shaping the surfa...

Bovine pericardium (BP) is widely used in surgery and is commonly used as a patch after arteriotomy in cardiovascular surgery. BP patches have several advantages compared with prosthetic patches, including superior biocompatability, easy handling, less suture line bleeding, and possibly reduced rates of infection. These advantages of BP have led to its common use during carotid endarterectomy (...

A new voltage-clamp apparatus for the squid axon has been implemented to enable recording of currents through small areas of axon membrane. The performance of this clamp was tested by recording total sodium currents from perfused axons (I total) and sodium currents from small membrane patches (I patch), which were recorded from inside the axon with an L-shaped pipette. The I patch records, alth...

The urokinase-type plasminogen activator receptor (uPAR) is a glycosylphosphatidyl inositol-anchored protein that mediates cell adhesion to the extracellular matrix protein vitronectin (VN). We demonstrate here that this cell adhesion process is accompanied by the formation of an adhesion patch characterized by an accumulation of uPAR into areas of direct contact between the cell and the matrix...

The human visual system is more sensitive to symmetry than to repetition. According to the so-called holographic approach [J. Math. Psychol. 35 (1991) 151; Psychol. Rev. 103 (1996) 429; Psychol. Rev. 106 (1999) 622], however, this perceptual difference between symmetry and repetition depends strongly on spatial scaling. This was tested in three experiments, using symmetry and repetition stimuli...

Background: Final exam is one of evaluation methods of students. We can utilize indexes such as difficulty index and discrimination index in order to analyze each test questions or to determine questions taxonomy. However, these methods have inter- testing look and do not consider the relationship between various tests results. Inter correlation between final exam score and the average indirect...

It is estimated that over one billion milkweed stems need to be restored sustain the eastern North American migratory population of monarch butterflies; where and in what context should placed on landscape key addressing habitat deficits. We assessed how amount appropriate surrounding a particular patch affects presence reproduction. To ensure restoration efforts are targeted towards areas maxi...

Urban green space is an important refuge of biodiversity in urban areas. Therefore, it is crucial to understand the relationship between the landscape pattern of green spaces and biodiversity to mitigate the negative effects of urbanization. In this study, we collected insects from 45 green patches in Beijing during July 2012 using suction sampling. The green patches were dominated by managed l...

Land-use changes result from in the human population, their activities, and social environmental which occur a complex dynamic manner. The change of forested areas to non-forested areas, also known as deforestation, is land-use change. Deforestation influences land cover by creating specific distribution pattern (fragmentation). Almost entire forest has been fragmented into smaller but each the...
