Inferences in a quantile regression are complicated when there exist a large number of candidate markers, together with some prespecified controlled covariates. In this study, we develop a new and ...

The proposed estimator takes the form of a nonlinear functional of derivatives of conditional expectations and is shown to provide estimated quantile functions that are uniformly consistent over a ...

Metals, particularly nickel and vanadium, and sulfate particles are the components of fine particulate air pollution (PM2.5) ...

Metals, particularly nickel and vanadium, and sulphate particles -- components of fine particulate air pollution (PM2.5) -- can worsen asthma and lead to hospitalisation, according to ...

The study showed that for each decile increase in the pollutant mixture, asthma hospitalisations increased 10.6 per cent in children and 8 per cent in adults ...

Metals, particularly nickel and vanadium, and sulfate particles are the components of fine particulate air pollution (PM2.5) that most strongly contribute to the association between long-term exposure ...

Over very long intervals, short-term random fluctuations (“noise”) cancel one another – and ever clearer and steadier signals emerge.

A Tesla Model Y L prototype caught near the Nurburgring racetrack confirms the long-wheelbase variant of the electric crossover will also be sold in Europe ...
