Most coccoliths have a double layer of crystals located at the edge of the coccolith base plate and a perforated central area of one crystal thickness where the crystals form an ellipse, which is linked to the outer edge of the coccolith by radial lines of crystals. There may be more extra...
Method 2: through creating an ellipseAn ellipse is defined by four parameters:Center of ellipse Rotation angle of the semi-major axis with respect to local east Semi-major axis and semi-minor axis in degreesCreate an ellipse centered at (30N, 95E), with a semi-major axis of 4.2 degrees...
The area inside the white ellipse refers to a DDRX grain formed by building mechanism. (a) and (c-e) have the same coordinate system. The color code shown in (e) can be used for all cases. HAGBs and LAGBs are shown by black (darker) and white (lighter) colors, respectively. ...
Here we develop and apply a data-driven approach to assess urban livability using POIs and other readily available open-source spatially-explicit data. We focus on Shanghai, which is a city characterized by significant variability in terms of socioeconomic characteristics and access to services withi...
think of the multiple centers of the ellipse. A redefinition of decision-making that takes digital technology and collaboration into consideration creates such a formwork that will help the architect to communicate effectively with multi-disciplinary teams. To move from a circular to an elliptical mode...

because populations of many wild relatives are under threat from habitat loss and degradation, there is an urgent need to collect and conserve crop wild relatives (CWRs) and to do so using methods that maximize genetic and environmental breadth. Such collections need to be characterized in ways ...
A simple, transparent, two-dimensional, nonlinear model of cell reorientation is constructed in this paper. The cells are attached to a substrate by “
Following the same two-dimensional parametrization of the invariant surface as the previous section, a pair of master variables (ηk,η̇k) is chosen and the remaining coordinates are described in terms of this pair. An additional transformation into polar coordinates is used to change the ...
The most commonly used equipment, the Andreason pipette, is described by Allen(1). In the second method, which involves the use of the sedimentation balance, particles settle on an immersed balance pan which is continuously weighed. The largest particles are deposited preferentially and consequently...
