Data analysts consider standard regression models (e.g., generalized linear model) or nonparametric smoothing techniques (e.g., loess or splines) when examining the association between two variables. Before this step, a quantile-based summarization is typically used for exploring the exposure-response relationship. Unfortunately, these exploratory approaches may not be optimal or efficient for ...

kawasaki disease (kd) is an acute vasculitis syndrome of unknown etiology. it occurs in infants and young children, affecting mainly small and medium-sized arteries, particularly the coronary arteries. generalized microvasculitis occurs in the first 10 days, and the inflammation persists in the walls of medium and small arteries, especially the coronary arteries, and changes to coronary artery ...

In mobile robotics, pure geometric representations may not be well suited for navigation in large scale environments. New models combine topological and metrical information to give compact and eecient representations. In this paper, we brieey remind the outlines of the construction of our Vorono-like graph and give further details about its implementation in a real environment. Several trials ...

By electrically segmenting, and series-connecting an InP ridge laser, we have demonstrated 12-stage lasers with 409% differential efficiency and 2.6mA threshold, as well as 3-stage lasers with 51ohm input impedance and 126% differential efficiency.

Introduction. Bystanders at overdose events often hesitate to call 911 due fear of police involvement. To address this, in 2016, British Columbia Emergency Health Services (BCEHS) introduced a policy not routinely inform events. This study explores change attended after the was implemented. Methods. Data on were derived from naloxone administration forms BC’s Take-Home Naloxone (THN) kits retur...

Photovoltaic (PV) systems with a battery back-up form an integral part of distributed generation systems and therefore have recently attracted a lot of interest. In this paper, we consider a system of charging a battery from a PV panel through a current mode controlled boost dc-dc converter. We analyze its complete nonlinear/nonsmooth dynamics, using a piecewise model of the converter and reali...

This paper investigates burst segmentation for the evaluation of acoustic cues used to identify unvoiced French stops. Unlike other works which utilize a fixed length window, our approach consists in segmenting bursts into transient and frication noise. The transient is found by minimizing the sum of spectral variances of transient and frication noise over the burst. The spectral variance crite...
