TY - JOUR T1 - Tetraeffective causes of mortality and survivorship JF - bioRxiv DO - 10.1101/039438 SP - 039438 AU - Michael Epelbaum Y1 - 2016/01/01 UR - http://biorxiv.org/content/early/2016/05/28/039438.abstract N2 - Every tetraeffective cause of mortality and survivorship negatively and positively affects mortality and negatively and positively affects survivorship. There is some scientific evidence of tetraeffective causes of mortality and survivorship, and strong rationales suggest that every cause of mortality and survivorship is tetraeffective. However, until now, tetraeffective causes of mortality and survivorship have remained unidentified, unnamed, unrecognized, unclear, misconceived, unspecified, and unexplained. Here I show that every tetraeffective cause of mortality and survivorship combines corresponding at least one mortacause and at least one vitacause; “mortacause” refers here to a cause-specific component that positively affects mortality and negatively affects survivorship, and “vitacause” refers to a cause-specific component that positively affects survivorship and negatively affects mortality. Best-fitting specifications ∂Y/∂(Xp) = a + bXp such that sign(a) = −sign(bXp) of respective tetradic effects of age, lifespan, contemporary aggregate size, lifespan aggregate size, and historical time on humans’ and medflies’ mortality and survivorship reveal here mortacauses and vitacauses of respective tetraeffective causes of mortality and survivorship; in these specifications components a and bXp indicate a mortacause and a vitacause of a tetraeffective cause X of mortality or survivorship Y. Thus mortacauses, vitacauses, and tetraeffective causes of mortality and survivorship are identified, named, recognized, elucidated, conceptualized, specified, explained, and demonstrated. ER -
