This paper builds on the previous paper by the author, where a relationship between Zhedanov’s algebra AW (3) and the double affine Hecke algebra (DAHA) corresponding to the Askey–Wilson polynomials was established. It is shown here that the spherical subalgebra of this DAHA is isomorphic to AW (3) with an additional relation that the Casimir operator equals an explicit constant. A similar resu...

PURPOSE Elevated levels of human telomerase (hTERT) mRNA in tumors is a marker for poorer survival in patients with stage I non-small cell lung cancer (NSCLC). A functional variant of MNS16A-short tandem repeats in hTERT (S allele) is associated with higher expression levels of hTERT mRNA compared with the MNS16A-long (L) allele. It is unknown, however, whether or not the hTERT MNS16A variant g...

The development and structure of orientation (OR) and ocular dominance (OD) maps in the primary visual cortex of cats and monkeys can be modelled using the elastic net algorithm, which attempts to find an 'optimal' cortical representation of the input features. Here we analyse this behaviour in terms of parameters of the feature space. We derive expressions for the OR periodicity, and the first...

The Wilcoxon rank-sum test is widely used to test the equality of two populations, because it makes fewer distributional assumptions than parametric procedures such as the t-test. However, the Wilcoxon rank-sum test can be used only if data are independent. When data are clustered, tests based on generalized estimating equations (GEEs) that generalize the t-test have been proposed. Here we deve...

We give a recursive algorithm for the computation of the first and second order derivatives of the entropy of a periodic autoregressive process with respect to the autocovariances. It is an extentions of the periodic Levinson-Durbin algorithm. The algorithm has been developed for use at one of the steps of an entropy maximisation method developed by the authors. We give numerical examples of en...

Aim Hemorrhage from pelvic fracture is a major cause of mortality after blunt trauma. Several studies have suggested that early fibrinogen supplementation improves outcomes of traumatic hemorrhage. Thus, we revised our massive transfusion protocol (MTP) in April 2013 to include early off-label administration of fibrinogen concentrate. The objective of this study was to evaluate the impact of th...

The study investigated the impact of non-oil revenue on economic growth Nigeria for period 1981 to 2019. Autoregressive Distributed Lags (ARDL) technique was adopted alongside unit root test, which showed that in all cases, variables level form were non-stationary but their first differences found be stationary. This shows (including growth) are co-integrated at order 1. short run diagnostic te...
