Towards automated first-order abduction: the cut-based approach
(OXFORD UNIV PRESSOXFORD, 2012)
Traditional abduction imposes as a precondition the restriction that the background information may not derive the goal data. In first-order logic such precondition is, in general, undecidable. To avoid such problem, we ...
Perfect Simulation of a Coupling Achieving the (d)over-bar-distance Between Ordered Pairs of Binary Chains of Infinite Order
(SPRINGER, 2010)
We explicitly construct a stationary coupling attaining Ornstein`s (d) over bar -distance between ordered pairs of binary chains of infinite order. Our main tool is a representation of the transition probabilities of the ...
A reduced-order observer for velocity estimation of N-link manipulators
(Acta Press, 2000-01)
An exponentially nonlinear reduced-order observer for robot manipulators is developed. Velocity estimation of N-link manipulators is performed by integrating only N differential equations. Consequently, computational effort ...

Long-range spin chirality dimer order in the Heisenberg chain with modulated Dzyaloshinskii-Moriya interactions
(American Physical Society, 2019-05-31)
The ground-state phase diagram of a spin S = 1 2 XXZ Heisenberg chain with spatially modulated Dzyaloshinskii-Moriya interaction H= n{J(Sx nSx n+1 +Sy nSy n+1 )+JzSz nSz n+1 +[D0 +(−1)nD1](Sx nSy n+1 −S y nSx n+1 )}is ...
Existence results for a damped second order abstract functional differential equation with impulses
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
In this work we study the existence and regularity of mild solutions for a damped second order abstract functional differential equation with impulses. The results are obtained using the cosine function theory and fixed ...
Higher-order theories from the minimal length
(2016-06-10)
We show that the introduction of a minimal length in the context of noncommutative space-time gives rise (after some considerations) to higher-order theories. We then explicitly demonstrate how these higher-derivative ...
Charge-ordering transition in (TMTTF)2X explored via dilatometry
(2013-08-28)
Charge-ordering phenomena have been highly topical over the past few years. A phase transition towards a charge-ordered state has been observed experimentally in several classes of materials. Among them, many studies have ...
