Transforming growth factor beta (TGFβ1, β2, and β3) are 25 kDa disulfide-linked homodimers that regulate many aspects of cellular functions, consist of proliferation, differentiation, adhesion and extracellular matrix formation. TGFβs mediate their biological activities by binding of growth factor ligand to two related, functionally distinct, single-pass transmembrane receptor kinases, known as...
Motivated by problems of anomaly detection, this paper implements the Neyman-Pearson paradigm to deal with asymmetric errors in binary classification with a convex loss. Given a finite collection of classifiers, we combine them and obtain a new classifier that satisfies simultaneously the two following properties with high probability: (i), its probability of type I error is below a pre-specifi...
Introduction: Medical errors cause serious and often preventable injuries to patients. Studying human errors and their use as an opportunity for learning is a key factor in the effort to improve patient safety and quality of care in the hospitals. The purpose of this study was to identify and evaluate human errors to reduce their risks in nursing personnel using the Human Error Evaluation and R...
In light of recent results by Verd u and Han on channel capacity, we examine three problems: the strong converse condition to the channel coding theorem, the capacity of arbitrary channels with feedback and the Neyman-Pearson hypothesis testing type-II error exponent. It is rst remarked that the strong converse condition holds if and only if the sequence of normalized channel information densit...
BACKGROUND In biomedical research, response variables are often encountered which have bounded support on the open unit interval--(0,1). Traditionally, researchers have attempted to estimate covariate effects on these types of response data using linear regression. Alternative modelling strategies may include: beta regression, variable-dispersion beta regression, and fractional logit regression...
Introduction: The main cause of incidents is human error. The occurrence of these errors in the use of medical equipment can result in harm to the patient, the destruction of equipment, the imposition of economic damages, and the deterioration of the credentials of the health sectors. Hence, the identification, evaluation and management of errors in the use of these equipment is very critical. ...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Electricity-related occupational accidents are the fifth leading cause of occupational deaths. One of the major causes of occupational accidents is human error. That is why the human role as a cause of the accident is so important and must be considered during risk assessment. The purpose of this study is to present a Fuzzy-HERAT human error assessment method, which can be used to assess the pr...
