Objective: To examine the role of the number of lymph nodes examined(NLNE) on the prognosis of patients with curatively resected gallbladder carcinoma(GBC). Methods: The clinicopathological data and prognosis of 401 patients with GBC who underwent radical surgery from six institutions of China from January 2013 to December 2017 were analyzed retrospectively. There were 153 males(38.2%) and 248 females(61.8%), with age of (62.0+/-10.5) years (range: 30-88 years). Fifty-three patients(22.2%) were ...

Abstract Importance measures have been widely used in system reliability design and optimization to find out system weaknesses. But the existing importance measures are hard to identify the dynamic weakness effectively for systems subjected to repeated and random load. Based on the stress-strength interference (SSI) model, this paper aims to develop a dynamic importance measure for k-out-of-n: G systems under repeated random load. At first, the importance measure for systems under repeated rando...

Abstract Mission success probability (MSP) is an important measurement to evaluate the performance of phased-mission systems (PMSs). The PMSs consist of some subsystems in series, and each subsystem is made of some k-out-of-n structures with repairable component modules. Adjusting the reliability and maintainability of components can improve the MSP of repairable PMSs. Therefore, the objective of MSP optimization for PMSs with repairable component modules is to maximize the MSP considering the c...

Importance measures in reliability systems are used to identify weak single component or multiple components in contributing to proper functioning of the system. They can be used to analyze the structure optimization with component reliabilities for reconfigurable systems, and solve the system optimization problem for a kind of component assignment problem for the consecutive k out of n systems. In reconfigurable systems, the system structure can be changed by reordering the components. The opti...
