In 1991 Dr. Guarente decided to study the basis of aging, then considered an intractable and unpromising field of research.
Most VRPs are computationally intractable, and the field has inspired significant developments in exact algorithms and heuristics, among these sophisticated mathematical programming approaches and metaheuristics.
The Wallabies over the last decade have built, in effect, a resounding multi-squad rebuttal to Tolstoy's old quip about families: all unhappy Wallabies sides are unhappy in the same way, lost amid a seemingly intractable tangle of on-field inconsistency, off-field idiocy, ego-driven preening and simple lack of passion.
Yet the engineering of functionally appropriate human-device interfaces represents an intractable challenge in the field.
One of the most common side effects of mesiotemporal lobe resection in patients with medically intractable epilepsy are visual field defects (VFD).
In the mid-nineteen-fifties, Hugh Everett was finishing his degree at Princeton when he came up with the many-worlds interpretation of quantum mechanics, which was then a radical approach that used the concept of parallel universes and a mountainous amount of math to resolve previously intractable problems in the field (a brief exegesis is here).
Spock (Star Trek) In biology, as in other fields, seemingly intractable problems can provide an opportunity to rethink long-standing scientific approaches.
Since velocity parameter is included in boundary or initial condition, there is intractable obstacle when integrating the field equations.
The immune system is known to be distributed in terms of control, parallel in terms of operation, and adaptive in terms of functions, all the features of which are desirable for solving complex or intractable problems faced in the field of artificial intelligence [27].
