Artificially produced chemical elements heavier than uranium have been known for more than seventy years and the number of superheavy elements continues to grow. Presently 26 transuranic elements are known. This paper examines the earliest scientific interest in the very heavy elements and the related question of an upper limit of the periodic system. In the period from the 1880s to the early 1...

Motivations for drawing hierarchical structures are probably as diverse as datasets to visualize. This ubiquity of tree structures has lead to a manifold of tree layout algorithms and tree visualization systems. While many tree layouts exist, increasingly massive data sets, expanding computational power, and still relatively limited display space make tree layout algorithms a topic of ongoing i...

A novel method and a framework called Memory-Based Forecasting are proposed to forecast complex and timevarying natural patterns with the goal of supporting experts’ decision making. This paper targets the local precipitation phenomena captured as echo patterns in weather radar images, and aims to realize a tool that supports weather forecasters. In our framework, past image patterns similar to...

It has been suggested that language learners prefer phonologically natural patterns overunnaturalones(McCarthy&Prince,1995;Tesar&Smolensky,1993,2000).Various researchers have cited evidence for this assertion based on production (Demuth, 1995; Gnanadesikan, 1995) and perception (Jusczyk, Smolensky, & Allocco, 2002). Two experiments presented in this article test whether 9-month-old infants lear...

We develop a method for the simultaneous restoration and halftoning of ngerprints using the \M-lattice", a new non-linear dynamical system. This system is rooted in the reaction-diiusion model, rst proposed by Turing to explain morphogenesis (the formation of patterns in nature). But in contrast with the general reaction-diiusion, the state variables of the M-lattice are guaranteed to be bounde...

Niels Bohr wrote: " There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we can say about Nature. " In an analogous way, von Weizsäcker suggested that the notion of the elementary alternative, the " Ur " , should play a pivotal role when constructing physics. Both appr...

This paper seeks to uncover dominant configurations of inter-organizational relationships across the USA and Japan in the automotive industry. We integrate relevant theoretical concepts from transaction cost economics, organization theory and political economy to develop a conceptual model of inter-organizational relationships based on the fit between information processing needs and informatio...
