Infiltrating anti-inflammatory monocytes modulate microglial activation through toll-like receptor 4/interferon–dependent pathways following traumatic brain injury

Mahmoud G. El Baassiri, Young Hak Chun, Simon S. Rahal, William B. Fulton et autres

BACKGROUND: Traumatic brain injury (TBI) is the leading cause of morbidity and mortality in the pediatric population. Microglia and infiltrating monocyte-derived macrophages are crucial immune cells that modulate the neuroinflammatory response following TBI. Using C34, a novel pharmacologic toll-like receptor 4 inhibitor, …

Economic design of multiple inspection plans via the expectation-maximization algorithm

Young Hak Chun

Because of inspection errors, expensive items such as computer chips are usually inspected more than once with the same testing device to further improve the quality of accepted items. Many researchers have considered various multiple inspection plans that minimize the expected total …

Imperfect inspection with directional information: A general failure probability model

Young Hak Chun

Suppose that the entire sequence of items produced is divided into a stream of nondefective items, followed by a stream of defective items. We propose a sequential inspection procedure for the production process that has a general failure probability–increasing, constant, or decreasing …

Generalized run tests for statistical process control

Young Hak Chun

In a sequence of elements, a run is defined as a maximal subsequence of like elements. The number of runs or the length of the longest run has been widely used to test the randomness of an ordered sequence. Based on two …

Information economics approach to the performance evaluation of error-prone internal auditors

Improved method of estimating the product quality after multiple inspections

Young Hak Chun

A complex product is often inspected more than once in a sequential manner to ensure the product’s quality. Based on the number of defects discovered during each round of inspection process, we can estimate the number of defects still remaining in the …
