Let E 2 denote the ring of entire functions on C 2. For f ∈ E 2, set D 1(f) P x f y P y f x. If D 1( E 2) is dense in E 2, then C [ P,Q] = C[ x,y]. The question whether or not D 1( E 2) is dense in E 2 is redu
Another conditional operator is ?:, which can be thought of as shorthand for an if-then-else statement (discussed in the Control Flow Statements section of this lesson). This operator is also known as the ternary operator because it uses three operands. In the following example, this operator...
The question mark must appear on the same line as the first argument. In Ruby 1.8, the colon must appear on the same line as the second argument. In Ruby 1.9, however, a newline is allowed before the colon. You must follow the colon by a space in this case, however, so it doesn...
In addition to the question of motivation, our experiment also exhibited several other limitations that in turn raise questions for future work. First, as noted earlier the levels of cooperation observed in our experiment were high relative to previous experiments. Although we have proposed a number...

Use intitle: and the – operators to find listicles related to your product or service that your business isn’t included in. For example, for a gardening supply store, you could use intitle: “best nurseries” and -your business name. You could also use the loc: operator to focus on ...
Haven't the Intel MKL folks already done this with calls to ?gemm and so forth? They would be far better at doing this than me. I posted a question about this in MKL forum. If I find out anything good, I'll report that here. By the way, how would gemm compare to MATMUL for ...
First Research Question is: “What are the main variables influencing mobile services’ customer satisfaction?”. Our second Research Question is the following: “What are the main variables influencing the switching intention in mobile services?”. Finally, Research Question 3 is “What are the ...
If lookup_value is smaller than the smallest value in the first row of table_array, HLOOKUP returns the #N/A error value. If range_lookup is FALSE and lookup_value is text, you can use the wildcard characters, question mark (?) and asterisk (*), in lookup_value. A question ...
Related to this Question Each set operator to a logical operator, in the following sense: for each binary set operator \square, there is a binary logical operator \bigcirc such that for any universal set U, and any subsets ...
