The pandas package in Python implements this operation as "melt" function which converts a wide table to a narrow one. The process of converting a narrow table to wide table is generally referred to as "pivoting" in the context of data transformations.
The zero-width space can be used to mark word breaks in languages without visible space between words, such as Thai, Myanmar, Khmer, and Japanese. [ 1 ] In justified text, the rendering engine may add inter-character spacing, also known as letter spacing, between letters separated by a zero-width space, unlike around fixed-width spaces.
The POWER1 from 1990 is the first microprocessor that used register renaming and out-of-order execution. This processor implemented register renaming only for floating-point loads. The POWER1 had only one FPU, so using renaming for floating-point instructions other than memory operation was unnecessary.
In relational algebra, a rename is a unary operation written as / where: . R is a relation; a and b are attribute names; b is an attribute of R; The result is identical to R except that the b attribute in all tuples is renamed to a. [1]
Relative to these axes, the position of any point in three-dimensional space is given by an ordered triple of real numbers, each number giving the distance of that point from the origin measured along the given axis, which is equal to the distance of that point from the plane determined by the other two axes.

The following describes techniques to auto-widen, or expand, any wp:wikitable, based on each user's default text-size set for their browser or device.. The major technique is to pad columns with column-spacers, as groups of non-breaking spaces ( ) at the end of each column, such as by template {{ns|15}}, where those spaces will shift below the column on narrow screens, to move the columns ...
First-generation (vacuum tube-based) electronic digital computer. 1961 $18.672B: $190.38B A basic installation of IBM 7030 Stretch had a cost at the time of US$7.78 million each. The IBM 7030 Stretch performs one floating-point multiply every 2.4 microseconds. [78] Second-generation (transistor-based) computer. 1964 $2.3B: $22.595B
Redox gradients form based on resource availability and physiochemical conditions (pH, salinity, temperature) and support stratified communities of microbes. [ 1 ] [ 5 ] [ 9 ] [ 8 ] [ 7 ] Microbes carry out differing respiration processes ( methanogenesis , sulfate reduction, etc.) based on the conditions around them and further amplify redox ...
