Ceratocystis fimbriata is a fungal plant pathogen that causes black rot on Ipomoea batatas. Based on inoculation studies on numerous tree species, the pathogen is known to be host specific. The closely related species, ...
According to research children living with HIV experience elevated levels of depression, anxiety, ADHD and disruptive behavioural disorders. Although South Africa’s paediatric population that is infected with the human ...
Background: Designated psychiatric facilities are responsible for the care, treatment and
reintegration of State patients. The necessary long-term care places a considerable strain on
health-care resources. Resource use ...

Distribution-free control charts gained momentum in recent years as they are more efficient in detecting a shift when there is a lack of information regarding the underlying process distribution. However, a distribution-free ...
Variable sampling interval (VSI) charts have been proposed in the literature for normal theory (parametric) control charts and are known to provide performance enhancements. In the VSI setting, the time between monitored ...

In this article, a subjective Bayesian approach is followed to derive estimators for the parameters of the normal model by assuming a gamma-mixture class of prior distributions, which includes the gamma and the noncentral ...

INTRODUCTION : Knowledge of the normal arterial diameter at a given anatomical point is the first step toward quantifying the severity of cardiovascular diseases. According to several studies, parameters such as weight, ...

A well-designed clinical trial requires an appropriate sample size with adequate statistical power to address trial objectives. The statistical power is traditionally defined as the probability of rejecting the null ...

Shewhart-type attribute charts are known to be inefficient for small changes in monitoring nonconformities. An alternative way is to use a time-weighted chart to monitor the time between events (TBE). We propose a one-sided ...

OBJECTIVE : The objective was to determine the preliminary psychometric performance of a
new clinical feeding scale to diagnose oropharyngeal dysphagia (OPD) in neonates.
METHODS : Twenty neonates with a median gestational ...
BACKGROUND : Advances in intra-abdominal pressure (IAP) measurement have enabled better monitoring and physiological manipulation of
patients with intra-abdominal hypertension or abdominal compartment syndrome. This study ...
Several studies have been conducted on decomposition patterns and rates of surface remains; however, much less are known about this process for buried remains. Understanding the process of decomposition in buried remains ...
The Canterbury Earthquakes struck the Canterbury region of the South Island of New Zealand between September 2010 and February 2011. The Earthquakes resulted in widespread structural damage to Christchurch, the main city ...
In this paper a bivariate gamma type distribution emanating from the diagonal elements of an inverse Wishart type distribution is developed; which in turn originates from the complex matrix variate elliptical class. From ...
In this paper we propose the beta slashed generalised half-normal distribution, which
includes some important distributions such as the half-normal, slashed half-normal and generalised
slashed half-normal distributions. ...
In this paper, we propose new results on a beta-Pareto class. This extension evolved
by using newly proposed class of beta distributions as generator distributions (F (x)) within the
generator-parent approach: H (x) = F ...
Early bactericidal activity of tuberculosis drugs is conventionally assessed using statistical regression modeling of colony forming unit (CFU) counts over time. Typically, most CFU counts deviate little from the regression ...
The inflammatory burden of the complex rheumatoid arthritis (RA) disease affects several organ-systems, including rheological properties of blood and its formed elements. Red blood cells (RBCs) are constantly exposed to ...
A meta-analysis (MA) combines similar studies resulting in a larger number of subjects to improve the degree of belief in the significance declared. Its major purpose is to increase the number of observations and the ...
