Abstract This paper introduces to the literature on Economic History a measure of persistence which is particularly useful when data are irregularly spaced. An illustration ten historical unevenly spaced series for Holland 1738 1779 shows merits methodology. It found that weight slave-based contribution in period has grown with deterministic trend pattern.

Studying the orbital stability of multi-planet systems is essential to understand planet formation, estimate stable time an observed planetary system, and advance population synthesis models. Although previous studies have primarily focused on ideal characterized by uniform separations, in reality a diverse range separations exists among planets within same system. This study focuses investigat...

A big challenge in academia is motivating students and helping them store information long-term. One known method to help retain spaced learning, which allows for certain time intervals concepts are re-tested versus waiting until the end of a block test learning objective. motivate implementing bonus opportunities that keep engaged material. We combine these methods via daily bulk review progra...

Vol. 1 (2013) pp. 37-46. ALGORITHMS FOR UNEQUALLY SPACED FAST LAPLACE TRANSFORMS FREDRIK ANDERSSON⇤ Abstract. We develop fast algorithms for unequally spaced discrete Laplace transforms with complex parameters, which are approximate up to prescribed choice of computational precision. The algorithms are based on modifications of algorithms for unequally spaced fast Fourier transforms using Gauss...

Spaced presentations of to-be-learned items during encoding leads to superior long-term retention over massed presentations. Despite over a century of research, the psychological and neural basis of this spacing effect however is still under investigation. To test the hypotheses that the spacing effect results either from reduction in encoding-related verbal maintenance rehearsal in massed rela...
