Consider two multi-dimensional digital signals, each with Ns samples. For some number of lags Nl Ns, the cost of computing a single cross-correlation of these two signals is proportional to Ns ×Nl. By exploiting several properties of Gaussian windows, we can compute Ns local cross-correlations, again with computational cost proportional to Ns×Nl. Here, local means the cross-correlation of signa...

BACKGROUND The efficiency of nasal surgeries can be determined by objective or subjective methods. We have assessed the effect of nasal obstruction after different nasal surgeries using Acoustic Rhinometry (AR) and Nasal Obstruction Symptom Evaluation (NOSE) Scale. METHODS Between May 2011 and May 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to ...

BACKGROUND Considerable evidence suggests that communication inequality is one potential mechanism linking social determinants, particularly socioeconomic status, and health inequalities. This study aimed to examine how dimensions of health communication outcomes (health information seeking, self-efficacy, exposure, and trust) are patterned by socioeconomic status in Japan. METHODS Data of a ...

Extended common-image-point (CIP) gathers can be constructed using wave-equation migration by preserving into the output image the non-zero spaceand timelags of the cross-correlation between the source and receiver wavefields. Correct wavefield reconstruction leads to focused events in the extended CIPs, while incorrect reconstruction leads to de-focused events that can be used for velocity mod...

Latent feature models are attractive for image modeling, since images generally contain multiple objects. However, many latent feature models ignore that objects can appear at different locations or require pre-segmentation of images. While the transformed Indian buffet process (tIBP) provides a method for modeling transformation-invariant features in unsegmented binary images, its current form...

A persistent controversy in the economics of higher education is the distributional consequences of tuition-fee subsidies. There are two points at issue. First, subsidies affect income distribution between rich and poor households, analyzed by cross-sectional studies. Second, there may also be long-run effects on income distribution, i.e., toward graduates who benefited from public higher educa...

This paper deals with the combination of classification models that have been derived from running different (heterogeneous) learning algorithms on the same data set. We focus on the Classifier Evaluation and Selection (ES) method, that evaluates each of the models (typically using 10-fold cross-validation) and selects the best one. We examine the performance of this method in comparison with t...
