Is a quantifier mismatch a problem for L1 Japanese learners of English?

open access: yesLingBaW, 2023
After identifying a linguistic difference between the English quantifier most and the Japanese quantifier hotondo ‘most’ we set out to find if the semantic difference between the two would constitute a learning problem for Japanese second language (L2 ...

Evaluation of two cooling devices for construction workers by a thermal manikin

open access: yesFashion and Textiles, 2017
Two kinds of wearable cooling devices were evaluated for their cooling effect by a thermal manikin. All measurements were conducted in a climatic chamber. The cooling fans worked almost 3 h.

Analysis of the fishing strategies of the yellowfin tuna (Thunnus Albacares) Eastern Pacific Fishery Based on Monte Carlo simulations of a density-dependent matrix model

open access: yesCiencias Marinas, 2000
 The effect of the fishing effort on the age structure has not been considered in many models. To consider both uncertainty and age structure, a density-dependent matrix model based on a discrete time-form of the logistic equation using the Leslie ...

Lack of sufficiently strong informative features limits the potential of gene expression analysis as predictive tool for many clinical classification problems

open access: yesBMC Bioinformatics, 2011
Background Our goal was to examine how various aspects of a gene signature influence the success of developing multi-gene prediction models. We inserted gene signatures into three real data sets by altering the expression level of existing probe sets. We

CONVERGENCE OF SOLUTIONS OF BILATERAL PROBLEMS IN VARIABLE DOMAINS AND RELATED QUESTIONS

open access: yesUral Mathematical Journal, 2017
We discuss some results on the convergence of minimizers and minimum values of integral and more general functionals on sets of functions defined by bilateral constraints in variable domains. We consider the case of regular constraints, i.e., constraints

A Comparison of Entropic Diversity and Variance in the Study of Population Structure

open access: yesEntropy, 2023
AMOVA is a widely used approach that focuses on variance within and among strata to study the hierarchical genetic structure of populations. The recently developed Shannon Informational Diversity Translation Analysis (SIDTA) instead tackles exploration ...

A robust multi-feature cut detection algorithm for video segmentation

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2010
Video segmentation is the first task in almost all video analysis applications. It consists in identifying the boundaries of the meaningful video units (shots). Without a doubt, cuts are the most common among production effects that characterize the shot
