We present a new invariant, calledslope, of colored link in an integral homology sphere and use this invariant to complete the signature formula for splice two links. develop number ways computing slope few vanishing results. Besides, we discuss concordance invariance establish its close relation Conway polynomials, on one hand, Kojima–Yamasaki<inline-formula content-type="math...

Substrate cover by corals, soft corals, sand, bare rock and algae was determined by several means for seaward reef slopes of the Central Indian Ocean atolls of Peros Banhos and Salomon, Chagos Archipelago, and in the lagoon of the former. Cover of hard substrate by coelenterates averages 80 O/O between 3 and 42 m, and calcareous algae dominate above and below these depths. Alcyonarian corals co...

[Purpose] This study examined the effects of ramp slope (1:12, 1:10, 1:8, and 1:6) on physiological characteristics and performance times of wheelchair users and the performance times of caregivers to determine which slope would be the best for wheelchairs, in order to propose a ramp slope that incorporates a universal design. [Subjects and Methods] Twenty-four healthy subjects were enrolled in...

We settle a problem of Dujmović, Eppstein, Suderman, and Wood by showing that there exists a function f with the property that every planar graph G with maximum degree d admits a drawing with noncrossing straight-line edges, using at most f(d) different slopes. If we allow the edges to be represented by polygonal paths with one bend, then 2d slopes suffice. Allowing two bends per edge, every pl...

Recent advances in control of humanoid robots have resulted in bipedal gaits that are dynamically stable on moderately rough terrain but are still limited to a small range of slopes. Humanoid robots, like humans, can take advantage of quadruped gaits to greatly extend this range. Cleverly designed gaits can provide robustness to rough terrain without requiring extensive feedback. In this paper,...

A dramatic failure of orientation constancy is documented in the perception of downhill slopes. Contrary to naïve expectation, steep downhill slopes look shallower from the edge than they do from back from the edge. Three experiments document and quantify this failure of constancy for real and virtual surfaces using a variety of dependent measures. Two additional studies document overestimation...
