This study explored the attributes of languages to which listeners attend, using magnitude estimation and multidimensional scaling techniques. In magnitude estimation. lislcners assign any numerical value to a set of stimuli. In response to the question: Ilow similar is this language to English’? fifty college students assigned numerical values to spoken samples of foreign languages. The langua...
To carry out parameter estimation in the proposed multi-way blockmodel, we developed a variational EM algorithm in a similar fashion to (Airoldi, 2007; Jordan et al., 1999) with inference detailed as follows. N 1 and 1 ≤ k ≤ N 2. The latent variables X are assumed to follow distribution q(X). By Jensen's inequality, we obtain the following lower bound on the observed data log-likelihood: (A.1) ...
This paper presents a novel, general and intelligent approach to multiresponse process optimisation, whose purpose is to obtain a single optimum setting of process parameters that meets specifications of all considered, possibly correlated, responses. The approach is based on Taguchi quality loss function, multivariate statistical methods: Principal componenet analysis and Grey relational analy...

We consider the problem of quantifying temporal coordination between multiple high-dimensional responses. We introduce a family of multi-way stochastic blockmodels suited for this problem, which avoids pre-processing steps such as binning and thresholding commonly adopted for this type of problems, in biology. We develop two inference procedures based on collapsed Gibbs sampling and variational...
We introduce a new detection-based method that is able to track multiple objects from a single camera. The method is built upon an approach that combines Kalman filtering and the Expectation Maximization (EM) algorithm. The benefit of this approach is that soft assignment of the detections to corresponding objects can be performed automatically using their a posteriori probabilities. This is a ...
The nerve growth cone is bi-directionally attracted and repelled by the same cue molecules depending on the situations, while other non-neural chemotactic cells usually show uni-directional attraction or repulsion toward their specific cue molecules. However, how the growth cone differs from other non-neural cells remains unclear. Toward this question, we developed a theory for describing chemo...
Cells and organisms are regularly exposed to a variety of stresses, and effective responses are a matter of survival. The article describes a multi-scale experimental and dynamical modeling analysis that clearly indicates concerted stress control in different temporal and organizational domains, and a strong synergy between the dynamics of genes, proteins and metabolites. Specifically, we show ...
Hemodynamic responses, in general, and the blood oxygenation level-dependent (BOLD) fMRI signal, in particular, provide an indirect measure of neuronal activity. There is strong evidence that the BOLD response correlates well with post-synaptic changes, induced by changes in the excitatory and inhibitory (E-I) balance between active neuronal populations. Typical BOLD responses exhibit transient...
In this paper, we present the first experimental demonstration of double- and triple-band negative refraction index meta-foils in the terahertz (THz) region. Multi-band meta-foils constructed by multi-cell S-string resonators in a single structure exhibit simultaneously negative permittivity and negative permeability responses at multiple frequencies. The phenomena are confirmed by numerical si...
