Although land–atmosphere coupling is thought to play a role in shaping themean climate and its variability, it remains difficult to quantify precisely. The present study aims to isolate relationships between early morning surface turbulent fluxes partitioning [i.e., evaporative fraction (EF)] and subsequent afternoon convective precipitation frequency and intensity. A general approach involving...
A long time-series study was conducted over 15 yr (1989–2004) to measure particulate organic carbon (POC) flux as an estimate of food supply reaching .4,000-m depth in the northeast Pacific. Sequencing sediment traps were moored at 3,500-and 4,050-m depth, 600 and 50 m above the seafloor, respectively, to collect sinking particulate matter with 10-d resolution. POC fluxes were compared with thr...
OBJECTIVES We sought to evaluate whether echocardiographic diastolic function indices correlate with myocardial iron and systolic function in patients with transfusion-dependent thalassemia (TDT) who are at risk for cardiomyopathy. BACKGROUND In thalassemia syndromes, there is an important clinical need to risk stratify patients for the development of iron-overload cardiomyopathy so that chel...
OBJECTIVE To evaluate the efficacy of a novel lipopolysaccharide (LPS) antagonist, E5531, in blocking LPS-induced cardiac responses including myocardial depression (as assessed by relatively load-independent echocardiographic indices of contractility) in a human model of experimental endotoxemia. DESIGN Randomized, prospective, placebo-controlled, double-blind trial. SETTING ICU procedure r...
Cell-free RNA and protein synthesis (CFPS) is becoming increasingly used for protein production as yields increase and costs decrease. Advances in reconstituted CFPS systems such as the Protein synthesis Using Recombinant Elements (PURE) system offer new opportunities to tailor the reactions for specialized applications including in vitro protein evolution, protein microarrays, isotopic labelin...
the main purpose of this paper is to investigate the performance of nigerian insurance companies using data envelopment analysis (dea). because of the unavailability of the required data, the study is limited to ten nigerian insurance companies for the period of five years from 2008 to 2012. the input employed were commission expenses and management expenses, while premium and investment income...
In this paper, statistical, artificial neural networks and fuzzy based feature evaluation indices are analysed in order to determine the importance of prostate cancer prognostic markers. Seven prognostic markers are assessed in terms of 3 output classes using logistic regression as a statistical method, multilayer feedforward back propagation neural networks (MLFFBPNN) as a neural network tool,...
