Inference of variance components in linear mixed effect models (LMEs) is not always straightforward. I introduce and describe a flexible SAS ® macro (%COVTEST) that uses the likelihood ratio test (LRT) to test covariance parameters in LMEs by means of the parametric bootstrap. Users must supply the null and alternative models (as macro strings), and a data set name. The macro calculates the obs...

Readers may be surprised by the recent editorial of Dr. Rosenberg, ‘Current evidence is not in support of lipid rescue therapy in local anaesthetic systemic toxicity’. Lipid rescue therapy (LRT) is widely accepted and recommended for treating local anaesthetic systemic toxicity (LAST) but Dr. Rosenberg purports that the efficacy and safety data are insufficient to warrant its use for this indic...

This paper investigates the statistical detection of Jsteg steganography. The approach is based on the statistical model of Discrete Cosine Transformation (DCT) coefficients. The hidden information detection problem is case in the framework of Hypothesis testing theory. In an ideal context where all model parameters are perfectly known, the Likelihood Ratio Test (LRT) is presented and its perfo...

Patients with hepatocellular carcinoma (HCC) who are listed for liver transplantation (LT) are often treated while on the waiting list with locoregional therapy (LRT), which is aimed at either preventing progression of HCC or reducing the measurable disease burden of HCC in order to receive increased allocation priority. We aimed to synthesize evidence regarding the effectiveness of LRT in the ...

Introduction: In mechanically ventilated patients, ventilator-associated pneumonia (VAP) is a major cause of prolonged hospitalization with increased morbidity and mortality. There lack studies on the relationship between bacterial colonization ventilator circuit (VC) VAP. This study aimed to investigate role VC in development VAP identify antibiotic susceptibility trends for isolated strains. ...

Background and Aim: Combination of locoregional therapy (LRT) with systemic may improve the outcome survival patients hepatocellular carcinoma (HCC). This study aimed to compare clinical outcomes HCC who were treated LRT or without tyrosine kinase inhibitors (TKIs). Methods: In a single-center prospective ongoing study, data was analysed for 81 diagnosed either monotherapy (LRT group, n=29, 35....

The Lattice Radiotherapy (LRT) technique is mainly based on the GRID technology with the improved feature of the 3D treatment delivery. A 72 year old male presented with left shoulder pain due to a 6 cm pulmonary mass in the left upper lobe (LUL) histologically proven Non-Small Cell Lung Cancer (NSCLC) stage IIIA. In July 2011 he was treated in our center with LRT followed by conventional fract...

the authors have developed methods to characterize and quantify uncertainty in acoustic environmental predictions. We have developed methods for reflecting this uncertainty in tactical systems such as senor performance prediction, search plan recommendation, and track and detect systems that rely on environmental inputs. Uncertainty in performance prediction can result from model error and unce...

This paper presents a review of Bus Rapid Transit (BRT) systems in Australasia. It describes the major systems operating in Adelaide, Brisbane and Sydney, outlining their infrastructure, operations and development characteristics. The performance of these systems in terms of patronage, markets, operations and overall urban development impacts is described. Lessons learned in their implementatio...

Urban transportation services such as Bus Repid Transit (BRT) the main issue in circle of planning, Semarang City Government built an urban system for public so that there is cooperation preparation Trans BRT full development program. Understanding policy aspects at both central and regional levels can improve performance provide a broader perspective among policymakers to develop implement sys...
