Longevity of the Permian Emeishan mantle plume (SW China): 1 Ma, 8 Ma or 18 Ma?

1895-1900 Ma LAJP 2627:Ma

A sensitive and selective liquid chromatography tandem mass spectrometry (LC–MS/MS) method for determination of meropenem in rabbit plasma was developed. After addition of triazolam as internal standard (IS), protein precipitation by acetonitrile was used in sample preparation. Chromatographic separation was achieved on a Restek Allure (TM) PFP Propyl (2.1 mm × 100 mm, 5 μm) column with acetoni...

292-296 Ma LAJP 3128:Ma

A sensitive and simple liquid chromatography/electrospray mass spectrometry (LC-MS/MS) method for determination of gefitinib in rat plasma using one-step protein precipitation was developed. After addition of estazolam as internal standard (IS), protein precipitation by acetonitrile was used as sample preparation. Chromatographic separation was achieved on an SB-C18 (2.1 mm × 50 mm, 3.5 μm) col...

Testing for a Linear Ma Model against Threshold Ma Models

This paper investigates the (conditional) quasi-likelihood ratio test for the threshold in MA models. Under the hypothesis of no threshold, it is shown that the test statistic converges weakly to a function of the centred Gaussian process. Under local alternatives, it is shown that this test has nontrivial asymptotic power. The results are based on a new weak convergence of a linear marked empi...

New antiepilep revolution or ma INTRODUCTION

INTRODUCTION Epilepsy is common, with a lifetime prevalence of 2–5% of the general population (Goodridge & Shorvon 1983a; Goodridge & Shorvon 1983b, Shorvon 1990) and a point prevalence of between 4 and 8 per 1000 (Hauser et al. 1993). Epilepsy represents a signifi cant fraction of the workload for most neurologists, and indeed, never has specialist input been more necessary as the choice of an...
