61.  The foolproof profs with their mathematical models offer even less certainty.

62.  The guide was compiled by the Consumers Union, which created a mathematical model to determine the value of the benefits provided by each plan.

63.  The mathematical models we use at ACSI do not relegate customer satisfaction to the realm of anecdotes, assumptions, personal experiences, inferences or even simple correlations.

64.  The phenomenon of rhythmic clapping, the scientists reported last month in the journal Nature, follows a mathematical model for what are known as coupled oscillators.

65.  The researchers used mathematical models built around a Wal-Mart in Christiansburg, Va., and assumptions about the number of people using each entrance.

66.  The researchers applied this change in variability to a mathematical model for synchronization developed by a Japanese physicist, Yoshiki Kuramoto.

67.  The team revised the estimate using results of clinical studies and a mathematical model, Ho said.

68.  The team used sophisticated mathematical models and was reviewed by four leading scientists from outside the region.

69.  Their mathematical model, which is partly based on the behavior of thermonuclear explosions, suggests that shock waves are the likely cause of sonoluminescence.

70.  There is a growing realization among ecologists that the endgame for species is not nearly as straightforward as it is portrayed in mathematical models.
