In the xy-plane, point (r,s) lies on a circle with center at the origin. What is the value of r2 + s2 ? The circle has radius 2. The point (√2,−√2) lies on the circle. 选项: A、Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. B、Stat...
and the vortex core beneath takes the form of a compact, polarized cluster of singly quantized vortices (called solid core).b, With the escalation of frequency (here to 2 Hz), a fully formed hollow core emerges, behaving like a multiply quantized object. Dark vertical stripes in...
The vertical scale for these graphs is identical. (b), Temperature variation of the in-plane SdH oscillation amplitude in sample B (Vg 5 350 V). (c), Amplitude suppression with increasing temperature for four in-plane SdH MR oscillation peaks/troughs Rpk(T) (indicated by arrows in (b))...
An undirected graph can be constructed from a point cloud by connecting neighboring points to the query point. Neighbors can be selected based on a certain radiusraround the query point, or thekclosest neighbors can be selected. Ifrorkare chosen too high, many redundant edges will be formed,...
are uniformly distributed over a circle of radiusRin a single layer. The central vortex lies either in the same or in another layer. The problem has three parameters (R, Γ,α), where α is the difference between layer thicknesses. A limiting case of a homogeneous fluid is also considered...
Step 5: If the point was not determined to lie on the circle in Step 4, calculate the distance from the center of the circle to the given point and compare the distance to the radius to determine if the point lies inside or outside the circle. Determ...
The magnetic flux rope is among the most fundamental magnetic configurations in plasma. Although its presence after solar eruptions has been verified by spacecraft measurements near Earth, its formation on the Sun remains elusive, yet is critical to unde
(l) results in a requirement for 2π.r.lin surface area andπ.r2.lin volume. If the radius (r) is constant, as would normally be the case, cell surface area is directly proportional to volume, irrespective of length. Third, the geometry provides cells with an axis of polarity along ...
