UXExperimentalTerms.kif 783-797

If a list is the list of items viewed by an agent and a physical is an instance of accessing web page and the first of the list is equal to the physical,
then there doesn't exist the physical2 such that the physical2 is an instance of accessing web page and the agent is an agent of the physical2 and the time of existence of the physical2 happens earlier than the time of existence of the physical

consequent

(=> (and (equal ?A (ListSumFn ?L)) (greaterThan (ListLengthFn ?L) 1)) (equal ?A (AdditionFn (FirstFn ?L) (ListSumFn (SubListFn 2 (ListLengthFn ?L) ?L)))))	Merge.kif 3259-3269	If a real number is equal to the sum of a list and length of the list is greater than 1, then the real number is equal to (the first of the list and the sum of the sub-list from 2 to length of the list of the list)
(=> (and (inList ?INT ?LIST) (equal ?LIST (TimeIntervalListFn ?TIME ?DUR))) (equal (BeginFn ?TIME) (BeginFn (FirstFn ?LIST))))	Weather.kif 1949-1956	If an entity is a member of a consecutive time interval list and the consecutive time interval list is equal to ConsecutiveTimeIntervalList for at a time interval at a time duration is contained in TimeIntervalListFn, then the beginning of the time interval is equal to the beginning of the first of the consecutive time interval list
(=> (and (instance ?LIST List) (not (equal ?LIST NullList))) (equal (FirstFn ?LIST) (ListOrderFn ?LIST 1)))	Merge.kif 3233-3238	If a list is an instance of list and the list is not equal to null list, then the first of the list is equal to 1th element of the list
(=> (measuringListDuration ?LIST ?DURATION) (exists (?T) (and (equal ?T (TimeIntervalFn (BeginFn (WhenFn (FirstFn ?LIST))) (EndFn (WhenFn (LastFn ?LIST))))) (duration ?T ?DURATION))))	Weather.kif 1861-1869	If The Measuring for list a measuring list takes a time duration., then there exists a time interval such that the time interval is equal to interval between the beginning of the time of existence of the first of the measuring list and the end of the time of existence of the last of the measuring list and duration of the time interval is the time duration
