Consider the Hill operator Ty = −y′′ + q′(t)y in L2(R), where q ∈ L2(0, 1) is a 1periodic real potential. The spectrum of T is is absolutely continuous and consists of bands separated by gaps γn, n > 1 with length |γn| > 0. We obtain a priori estimates of the gap lengths, effective masses, action variables for the KDV. For example, if μn are the effective masses associated with the gap γn = (λ ...

Sir,?Can any of your readers give any information as to the nature of what has been called the " Hill Fever" of Mysore and the Deccan 1 In reading an account of malaria* recently, I came across the following: " The hill fever of Mysore occurs among bare rocks, stones and brown earth, at the hottest season from March to June, when the rocks in the sun show a surface temperature of 220?F. and rap...

This paper presents an adaptive version of the Hill estimator based on Lespki’s model selection method. This simple data-driven index selection method is shown to satisfy an oracle inequality and is checked to achieve the lower bound recently derived by Carpentier and Kim. In order to establish the oracle inequality, we derive non-asymptotic variance bounds and concentration inequalities for Hi...

The contraction of a muscle generates a force that decreases when increasing the contraction velocity. This "hyperbolic" force-velocity relationship has been known since the seminal work of A. V. Hill in 1938 [Hill AV (1938) Proc R Soc Lond B Biol Sci 126(843):136-195]. Hill's heuristic equation is still used, and the sliding-filament theory for the sarcomere [Huxley H, Hanson J (1954) Nature 1...

Data routing is one of the most important problems in parallel networks. Long latency in low dimensional networks can be solved by including segmented reconngurable buses (SRB). In addition to physical limitation we choose the segment length such that we may get the best resource utilization and minimize the average latency. After choosing the segment length, we have to arrange these segments c...

Most commonly used inductive rule learning algorithms employ a hill-climbing search, whereas local pattern discovery algorithms employ exhaustive search. In this paper, we evaluate the spectrum of different search strategies to see whether separate-and-conquer rule learning algorithms are able to gain performance in terms of predictive accuracy or theory size by using more powerful search strat...

We introduce new discretizations of the action for static quarks. They achieve an exponential improvement (compared to the Eichten-Hill regularization) on the signal to noise ratio in static–light correlation functions. This is explicitly checked in a quenched simulation and it is understood quantitatively in terms of the self energy of a static quark and the lattice heavy quark potential at ze...

In evolution theory the concept of a fitness landscape has played an important role, evolution itself being portrayed as a hill-climbing process on a rugged landscape. In this article it is shown that in general, in the presence of other genetic operators such as mutation and recombination, hill-climbing is the exception rather than the rule. This descrepency can be traced to the different ways...
