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.

In query language s, path expressions identify an object by describing how to navigate to it in some Graph data structure graph possibly implicit graph implicit of objects. For example, the path expression code p .Manager.Home.City code might refer the city of residence of someone s manager. Path expressions have been extended to support regular expression like flexibility. XPath is an example of a path expression language. In concurrency control , path expressions are a mechanism for expressing permitted sequences of execution. For example, a path expression like code read , write code might specify that either multiple simultaneous executions of code read code or a single execution of code write code but not both are allowed at any point in time.

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. To this end, a bacteria l expression Clone genetics clone may include a ribosome binding site Shine Dalgarno sequence to enhance translation of the gene of interest s mRNA, a Transcription genetics transcription termination sequence, or, in eukaryotes , specific sequences to promote the Posttranslational modification post translational modification of the protein product.

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 .
