A broad strategy is employed to detect and remove component level faults from various hardw...

We present an adaptive tester for the unateness property of Boolean functions. Given a function f : {0, 1}n → {0, 1} the tester makes O(n log(n)/ε) adaptive queries to the function. The tester always accepts a unate function, and rejects with probability at least 0.9 if a function is ε-far from being unate.

Variation in reproductive success has long been thought to be mediated in part by genes encoding seminal proteins. Here we explore the effect on male reproductive phenotypes of X-linked polymorphisms, a chromosome that is depauperate in genes encoding seminal proteins. Using 57 X chromosome substitution lines, sperm competition was tested both when the males from the wild-extracted line were th...

Parent ratings of temperament in infancy and childhood yield evidence for genetic influence in twin studies but not in adoption studies. The present study used the sibling adoption design to investigate teacher and tester ratings of temperament in middle childhood. When each child was 7 years old, ratings on the Colorado Childhood Temperament Inventory were obtained from a teacher and tester fo...

We give a unateness tester for functions of the form f : [n] → R, where n, d ∈ N and R ⊆ R with query complexity O( log(max(d,n)) ). Previously known unateness testers work only for Boolean functions over the domain {0, 1}. We show that every unateness tester for realvalued functions over hypergrid has query complexity Ω(min{d, |R|}). Consequently, our tester is nearly optimal for real-valued f...

Five early growth characters were examined in six races of Arabidopsis thaliana (L.) Heynh, their reciprocal F(1) hybrids (1974) and F(1) by tester hybrids, using a seventh race as a paternal tester. Three of the five characters were also examined at two nutrient levels in reciprocal F(1) hybrids (1972) of all seven races. Analyses of F(1) and F(1) by tester hybrids revealed significant materna...
