This paper presents a new way to assess robustness of claims from identi ed VAR work. All possible identi cations are checked for the one that is worst for the claim, subject to the restriction that the VAR produce reasonable impulse responses to shocks. The statistic on which the claim is based need not be identi ed; thus, one can assess claims in large models using minimal restrictions. The t...

OBJECTIVES We sought to assess the diagnostic accuracy and incremental prognostic value of delayed hyper-enhancement cardiac magnetic resonance (DHE-CMR) compared with electrocardiographic and transthoracic echocardiographic (TTE) parameters in such patients. BACKGROUND Utility of DHE-CMR in the diagnosis of patients with suspected cardiac amyloidosis (CA) has recently been demonstrated, but ...

Objectives To assess the effect of vitamin A supplementation in women of reproductive age in Ghana on cause- and age-specific infant mortality. In addition, because of recently published studies from Guinea Bissau, effects on infant mortality by sex and season were assessed. Design Double-blind, cluster-randomised, placebo-controlled trial. Setting 7 contiguous districts in the Brong Ahafo re...

Stock performance modeling using neural networks: A comparative study with regression models', Neural Networks. fully connected network, it is not sufficient to stop removing weights when b P() first increases. This is particularly true given that both SBP and OBD are greedy algorithms, and they neglect interactions between multiple inputs and weights. Thus, removing additional inputs or weight...

OBJECTIVE Aspartate aminotransferase to alanine aminotransferase (AST/ALT) ratio, reflecting liver disease severity, has been associated with increased risk of cardiovascular disease (CVD). The aim of this study was to evaluate whether the AST/ALT ratio improves established risk prediction tools in a primary care population. METHODS Data were analysed from a prospective cohort of 29 316 UK pr...

BACKGROUND Biomarkers may help clinicians predict cardiovascular risk. We aimed to determine if the addition of endocrine, metabolic, and obesity-associated biomarkers to conventional risk factors improves the prediction of cardiovascular and all-cause mortality. METHODOLOGY/PRINCIPAL FINDINGS In a population-based cohort study (the Study of Health in Pomerania) of 3,967 subjects (age 20-80 y...

BACKGROUND Early identification of meticillin-resistant Staphylococcus aureus (MRSA) carriers may be helpful for clinical and epidemiological reasons. AIM To identify and compare risk factors of previously unknown MRSA carriage on admission to 13 surgical wards in France, Greece, Italy, and Spain. METHODS The study was a prospective observational cohort study which enrolled consecutive pati...

(P being the pulsation period) could, therefore, assume any value. Moreover, if the disturbing force were periodic, a resonance of the free and forced periods would be immediately established and the amplitude of the oscillation greatly enhanced. Second-order effects, ignored in the present investigation, would thus probably soon become appreciable and could operate to destroy the resonance. Sh...
