The causes of slip and fall accidents, both in terms of extrinsic and intrinsic factors and their associations are not yet fully understood. Successful intervention solutions for reducing slip and fall accidents require a more complete understanding of the mechanisms involved. Before effective fall prevention strategies can be put into practice, it is central to examine the chain of events in a...

We propose a new method for estimating intrinsic dimension of a dataset derived by applying the principle of maximum likelihood to the distances between close neighbors. We derive the estimator by a Poisson process approximation, assess its bias and variance theoretically and by simulations, and apply it to a number of simulated and real datasets. We also show it has the best overall performanc...

We discuss a theorem of Csonka, Moravcsik, and Scadron on the nonexistence of purely kinematic parity experiments involving scattering processes with more than four particles. Such experiments can be carried out, even in the case of noncoplanar momenta in the center of mass frame, if the experimenter can construct coherent superpositions of some asymptotic states and their parity inverses, as o...

This paper discusses vibrotactile feedback in digital musical instruments. It compares the availability of intrinsic vibrotactile feedback in traditional acoustic musical instruments with the lack of vibrotactile feedback in most digital musical instruments. A short description of human sensory ability with regard to this form of feedback is given and the usefullness of vibrotactile feedback to...

Data streams can change their behavior over time and, when a significant change occurs, the rules governing the attributes reported by each event can also change. Moreover, data streams can be composed of events from several classes, and the rules governing the events of each class can also change depending on actual properties of the data. In this paper we propose a new technique to continuous...

Sport ability may be seen as relatively stable, genetically determined and not easily modified by practice, or as increasable with training, work and effort. Using the Implicit Association Test (IAT), the purpose of the present study is to examine whether the practice of a particular sport (swimming or basketball) can influence automatic beliefs about sport ability in these two sports. The IAT ...

Heart contains a variety of neurons known to influence cardiac functions. Little is known about the neurochemistry of these neurons. In this study, neurochemistry of intra cardiac neurons of the intrinsic cardiac ganglia was investigated. The technique used allows studying the morphology of the ganglionated nerve plexus found within the atria and great cardiac vessels as well as of individual n...
