Identification and isolation of COVID-19 infected persons plays a significant role in the
control of COVID-19 pandemic. A country’s COVID-19 positive testing rate is useful in
understanding andmonitoring the disease ...
Insurance loss data have peculiar features that can rarely be accounted for by simple parametric distributions. Thus, in this manuscript, we first introduce a new type of location mixture model: the mode mixture. By using ...
INTRODUCTION : The identification of classes of nutritionally similar food items is
important for creating food exchange lists to meet health requirements and for
informing nutrition guidelines and campaigns. Cluster ...

The gut microbiota has emerged as a key human health and disease determinant. However,
there is a significant knowledge gap regarding the composition, diversity, and function of the gut
microbiota, specifically in the ...
In the longitudinal data analysis we integrate flexible linear predictor link function and highcorrelated
predictor variables. Our approach uses B-splines for non-parametric part in the linear predictor
component. A ...
Shrinkage estimators are often used to mitigate the consequences of multicollinearity in
linear regression models. Despite the ease with which these techniques can be applied to small- or
moderate-size datasets, they ...

Semi- and non-parametric mixture of normal regression models are a flexible class of mixture
of regression models. These models assume that the component mixing proportions, regression
functions and/or variances are ...
Comparative bioavailability studies often involve multiple groups of subjects for a variety of reasons, such as clinical capacity limitations. This raises questions about the validity of pooling data from these groups in ...

Tuberculosis (TB) remains the second leading cause of death globally from a single infectious
agent, and there is a critical need to develop improved imaging biomarkers and aid rapid assessments
of responses to therapy. ...
In order to assess prognostic risk for individuals in precision health research, risk prediction models are increasingly used, in which statistical models are used to estimate the risk of future outcomes based on clinical ...
This study examined the effects of life design counselling on secondary students with career indecision in a resource-constrained community. Non-probability, purposive sampling was utilized to select 91 secondary students ...
BACKGROUND :
Nurses document wounds to direct and evaluate the care. People admitted to emergency departments with wounds should be regarded as potential forensic patients, requiring meticulous documentation for evidence ...
BACKGROUND : In livestock disease surveillance, spatial analysis methods play a major role in the identification of areas where the risk of disease could be higher. Though widely used in human health, their extent and depth ...
The COVID-19 pandemic has caused significant morbidity and mortality, as well as social and economic disruption worldwide in general and USA in particular. In order to reduce these effects, a global effort to develop ...
Since the emergence of the novel COVID-19 virus pandemic in December 2019, numerous
mathematical models were published to assess the transmission dynamics of the disease, predict
its future course, and evaluate the impact ...
Positive parenting behaviors such as parental monitoring and support can protect adolescents from alcohol use, either directly or through buffering risk factors such as perceived peer alcohol use. However, it is unclear ...

BACKGROUND
Established subcutaneous internal fixation techniques have shown a better quality of life with
reduced pain. However, complications still arise, with the most significant being injury of the
lateral femoral ...
