The title track was Coltrane s last studio recording the rest of the album was recorded at about the same time as Interstellar Space . To Be features Coltrane on flute , the only recording he made on the instrument for an entire track. As for the remainder, Coltrane s tenor seems to have acquired a denser, wider sound while retaining the free form of the late years. This is most evident on Offering, which follows its theme into a particularly radical example of overblowing. Track listing All tracks by John Coltrane.

Unreferenced date October 2007 Expression cloning is a technique in DNA cloning that uses expression vector s to generate a library of clones, with each clone expressing one protein. This expression library is then screened for the property of interest and clones of interest recovered for further analysis. An example would be using an expression library to isolate genes that could confer antibiotic resistance . Expression vectors Expression vectors are a specialized type of cloning vector in which the transcriptional and translational signals needed for the regulation of the gene of interest are included in the cloning vector. The transcriptional and translational signals may be synthetically created to make the expression of the gene of interest easier to regulate. Purpose Usually the ultimate aim of expression cloning is to produce large quantities of specific protein s.

Unreferenced date December 2009 In computer science , a Boolean expression is an Expression programming expression in a programming language that produces a Boolean value when evaluated, i.e. one of true or false . A Boolean expression may be composed of a combination of the Boolean constants true or false , Boolean data type Boolean typed variables, Boolean valued operators, and Boolean valued function s. Boolean operators Programmer s will often use a pipe symbol for OR, an ampersand & for AND, and a tilde for NOT. In many programming language s, these symbols stand for bitwise operation s. , && , and are used for variants of these operations. Other symbols are a for OR, a for AND, and an overscore for NOT. Examples The value for 5 3 is evaluated as true . 5 3 and 3 5 are equivalent Boolean expressions both of which would be evaluated as true .

Musical expression is the art of playing music with communication. The elements of music that comprise expression include dynamic indications, forte or piano, Musical phrasing phrasing , differing qualities of touch and articulation, color, intensity, energy and excitement all at the service of the composer s intention as best perceived by the performer. A performer aims to elicit responses of sympathetic feeling in the audience, and to excite, calm or otherwise manipulate the audience s physical and emotional responses. In a great artist, one can feel that it is the soul that is speaking, in lesser artists, the ego. In non artist performances, one can sometimes sense the soul of the composer in the absence of interpretation. Expression can be closely related to breath, and the voice s natural ability to express feelings, sentiment, deep emotions.

In the field of compiler optimization s, available expressions is an analysis algorithm that determines for each point in the program the set of expression programming expressions that need not be recomputed. Those expressions are said to be available at such a point. To be available on a program point, the operands of the expression should not be modified on any path from the occurrence of that expression to the program point. The analysis is an example of a forward data flow analysis problem. A set of available expressions is maintained. Each statement is analysed to see whether it changes the operands of one or more available expressions. This yields sets of available expressions at the end of each basic block , known as the outset in data flow analysis terms. An expression is available at the start of a basic block if it is available at the end of each of the basic block s predecessor s. This gives a set of equations in terms of available sets, which can be solved by an iterative algorithm. Available expression analysis is used to do global common subexpression elimination CSE . If an expression is available at a point, there is no need to re evaluate it.
