The phrase "a large sphere is" is correct and usable in written English.
It can be used when describing or defining a large spherical object or concept in various contexts, such as science, mathematics, or art.
Example: "A large sphere is often used in physics to demonstrate principles of gravity and motion."
Alternatives: "a big sphere is" or "a sizable sphere is".
Furthermore, a complicated two-level hierarchical nanostructure consisting of evenly distributed small spheres on the surface of a large sphere was found to have the virtues of both large and small spheres and therefore benefit the current enhancement considerably[5, 18].
When one or a few very remote objects are in the training set, a very large sphere is obtained which will not represent the data very well.
The large sphere is charged, insulated, and conducting.
The large sphere is taken to be infinitely massive, and the equation of motion of the point charge is computed using Jackson's equation (2.9) for the force between the two.
This relatively large sphere was imaged with the focus of the objective held fixed at the coverslip-buffer interface; this approach assured that the reflection from the (bottom) surface of the sphere closest to the coverslip-buffer interface was greater than the (top) reflection from the surface of the sphere that was furthest from the interface.
In zorbing, a person is strapped inside a large sphere, which is itself held inside a larger sphere by a cushion of air (the whole thing's called a zorb) and then rolled along the ground or, better yet, downhill.
Lying down inside a large sphere, one is bombarded by a stream of moving images and a cacophony of sounds, ranging from fighting robots, screaming children, naked women, Nazi storm troopers and astronauts in space.
These large spheres are expected to remain in orbit for decades, slowly decaying in altitude over time.
Large spheres are believed to consist of more differentiated cells or early progenitors than smaller spheres.
For the 5 subjects, average top half movement times for the small, medium, and large spheres were 1.2, 1.5, and 1.8 s, respectively.
