Multiple outcomes are commonly measured in:the study of birth defects. The reason is that most teratogens do not cause a single, uniquely defined defect, but rather result in a range of effects, including major malformations, ...
Abstract: The theory of estimation and inference in a very general class of latent variable models for time series is developed by showing that the distribution theory for the finite Fourier transform of the observable ...
We discuss latent variable models that allow for fixed effect covariates, as well as covariates affecting the latent variable directly. Restricted maximum likelihood and maximum likelihood are used to estimate model ...
This paper describes and applies a general approach for incorporating factors with structural equations into models for discrete choice. The approach gives form to the covariance matrix in random coefficient models. The ...
A dynamic model of a coupled train-girder-pier system is developed in this paper. Each vehicle in a train is modeled with 27 degrees-of-freedom for a 4-axle passenger coach or freight car, and 31 for a 6-axle locomotive. ...
Cell division in bacteria is facilitated by a polymeric ring structure, the Z ring, composed of tubulin-like FtsZ protofilaments. Recently it has been shown that in Bacillus subtilis, the Z ring forms through the cell ...
Previous research has shown that the ability to orient with the use of directional cues from the geomagnetic field is lateralized in three avian species: orientation is possible when the birds are restricted to use of their ...
In this paper, lateral-torsional buckling behavior of open-section thin-walled beams is investigated based on a geometrically nonlinear formulation, which considers the effects of shear deformations. A finite element ...
Lateral genetic transfer (LGT) involves the movement of genetic material from one lineage into another and its subsequent incorporation into the new host genome via genetic recombination. Studies in individual taxa have ...
Russell, Helen(Routledge Taylor & Francis Group, 2008)
In this article, an emerging framework for investigating and interpreting the experiences of learning in later life is presented. This framework is contextualized by a study in which the lived experiences of later-life ...
Russell, Helen(Linkoping University Electronic Press (LiU E-Press), 2011)
This paper is based on a qualitative study of later life computer learners and their learning experiences in Sydney, Australia. Participants were aged between 63 and 86 years and undertaking lessons from peer tutors in ...
The lattice parameters of a metallic nanoparticle decrease with its size. To describe this phenomenon, a model based on elasticity is developed in this paper. Using this model, we investigate the lattice contraction of a ...
Peterson, V. K(International Centre for Diffraction Data, 2005)
The measurement of lattice parameters using the Le Bail method was shown to be inappropriate for
a complex, low symmetry, structure, even with high resolution synchrotron diffraction data. The
method failed as a result ...
For periodic integrands with unit period in each variable, certain error bounds for lattice rules are conveniently characterised by the figure of merit rho, which was originally introduced in the context of number theoretic ...
Trillas, Cubillo and Castineira [Artificial Intelligence 117 (2000) 255-275] defined several interesting operators in orthocomplemented lattices. These operators give a quite general algebraic model for conjectures, ...
