Also, you don't notice this cone until there is precipitation for the radar to detect. To understand a radar's cone of silence, you have to first understand how the radar sends out its beam.

Remember, the asteroid is somewhere near the vertex of a large cone, and we don’t know where. If Earth is near the cone’s centerline, then as the cone narrows with better observations, we’re ...

SUBJECTS: Maths YEARS: 3–4, 5–6 An angle is formed when two straight lines, or rays, meet at a point, called a vertex. Angles are measured in degrees. An angle can also describe an amount of turn.

A quadrilateral is a four-sided shape, where the sides are straight and meet at four vertices. The prefix “quad” means four. There are several types of quadrilaterals. Can you name them?

Previous studies of depth and distance estimation with autostereoscopic 3D displays indicate the users do not necessarily exhibit better depth perception with such displays. Yet, users claim 3D ...

Vertex Pharmaceuticals (VRTX 1.88%) has climbed in the double digits this year and is trading around its highest ever. There are plenty of reasons for this top performance.

Vertex will leave 40% of the profits to CRISPR. Though Vertex takes the lion's share, the revenue from exa-cel likely won't come close to what it makes from its CF treatments.

W-band electromagnetic vortex-waves generated by a uniform circular array are tightly collimated by a paraboloidal reflector into a radiation cone with a small vertex angle and beam width. A low ...

ABSTRACT Objective: To determine the discrepancy of crown-root morphology of anterior teeth, using cone-beam computed tomography (CBCT), and to provide a guidance for proper torque expression. Methods ...

1 July 2022 Showering A charm quark in a parton shower loses energy by emitting gluons. The shower displays a “dead cone” of suppressed radiation around the quark for angles smaller than the ratio of ...
