x1 is a conjunction, stating that x2 (du'u) and x3 (du'u) are both true.

See also vlina.

In notes:

x1 is a logical alternation/disjunction, stating that x2 (du'u) and/or x3 (du'u) is/are true.
both statements x1 (du'u) and x2 (du'u) are true (logical conjunction)
v1 is an OR gate with input [pins] v2 and output [pins] v3 in circuit/system v4.
x1 is a logical 'if-else' (ternary conditional) statement saying that if x2 is true, then x3 is true (or performed), but otherwise/else (if x2 is not true, then) x4 is true (or performed).
x1 is a connective question, requesting the connective between x2 (du'u) and x3 (du'u) in that order, assuming that they are true.
x1 is a logical 'NOT' statement resulting from the (multiplicative) negation of/applying the 'NOT' operator to x2 (du'u); x1 is the logical negation/negative of x2.
x1 is a logical statement that x2 (du'u) is true regardless of/irrespective of/independent of/whether or not x3 being/is true.
x1 is a material conditional/'IF' statement (logical statement) saying that x2 (du'u) logically implies x3 (du'u) ("x3 is true if x2 is true; if x2, then x3; x2 being true is sufficient to guarantee the truth of x3").
x1 is a logical statement which says that x2 (du'u) being true logically implies (material implication) x3 being necessarily true, but in which the converse does not hold (it is certain that there are cases in which 'IFF' fails: x2 is not necessary for x3).
x1 is a logical XOR/mutual-contradiction/exclusive disjunction statement saying that only/exactly one of x2 and x3 can be true at any given time.
x1 is a logical statement of proposition-equivalence/is a biconditional/'IFF' statement saying that x2 (du'u) is true if and only if x3 is true ("x2 is logically equivalent to x3; x2 being true is sufficient and necessary for guaranteeing the truth of x3; x2 iff x3").
