[4]: 114 A DataFrame is a 2-dimensional data structure of rows and columns, similar to a spreadsheet, and analogous to a Python dictionary mapping column names (keys) to Series (values), with each Series sharing an index. [4]: 115 DataFrames can be concatenated together or "merged" on columns or indices in a manner similar to joins in SQL.

Log-polar coordinates in the plane consist of a pair of real numbers (ρ,θ), where ρ is the logarithm of the distance between a given point and the origin and θ is the angle between a line of reference (the x-axis) and the line through the origin and the point.
Connor McDavid had two goals and an assist to lead the Edmonton Oilers to a 5-2 win over the Ottawa Senators on Tuesday night. Evan Bouchard, Leon Draisaitl and Ryan Nugent-Hopkins also scored for ...
The first locally transmitted case of dengue fever in 2024 in Texas has been recorded in Cameron County, the Texas Department of State Health Services says.
(Reuters) -The Louisiana Department of Health said on Friday it has detected the first presumptive positive human case of H5N1 bird flu infection in the U.S. state.
The reference point (analogous to the origin of a Cartesian coordinate system) is called the pole, and the ray from the pole in the reference direction is the polar axis. The distance from the pole is called the radial coordinate, radial distance or simply radius, and the angle is called the angular coordinate, polar angle, or azimuth. [1]
Polar modulation makes use of polar coordinates, r (amplitude) and Θ (phase). The quadrature modulator approach to digital radio transmission requires a linear RF power amplifier which creates a design conflict between improving power efficiency or maintaining amplifier linearity. Compromising linearity causes degraded signal quality, usually ...
