Absence of a Barrier (in this case a heat disorder called hyperthermia) can also result in fever.\nTwo inhibitors (Aspirine and Tylenol) are able to reduce fever. Being Alive is a Requirement for observing fever.\n\nBarriers and Causes are dual of each other: Barriers are negated causes. Their absence is able to cause the effect.\n\nInhibitors and Requirements are also dual of each other: Inhibitors are negated Requirements.\n\nThe model is somewhat artificial with the nodes Being Alive (please note that this might be a real node in case of the population of some hospital's Intensive Care Unit, where the values are determined by automatic probe) and Hyperthermia.\n\nSource:\nBayesFusion, LLC Pneumonia 61 216 153 273 Tylenol Intake 368 116 473 181 Fever 226 396 285 432 Flu 88 74 178 141 Aspirin Intake 259 36 362 102 Being Alive 418 341 500 403 Bodily Temperature Balance 407 225 543 287 This simple qualitative model illustrates the interaction of Causes, Barriers, Requirements and Inhibitors in the DeMorgan gate.\n\nCauses (Flu and Pneumonia) are able to cause fever.
