Abstract Background The aim is to assess the validity and reliability of transbronchial needle aspiration (TBNA) of mediastinal and hilar adenopathies and to evaluate factors predictive of TBNA outcome.Methods We performed an analysis of prospectively collected data of patients (n = 580) who underwent TBNA (n = 685) from first due helmet January 19
This review provides a comprehensive analysis of the design, materials, fabrication techniques, and applications of flexible wearable antennas, with a primary focus on their roles in Wireless Body Area Networks (WBANs) and healthcare technologies.Wearable antennas are increasingly vital for applications that require seamless integration with the hu
Spatial crowdsourcing is an effective and novel method.In crowdsourcing systems, a centralized platform is traditionally used to allocate tasks and select workers.Centralized platforms always face following challenges: 1) How to ensure the rationality of tasks allocating; 2) How to ensure the payments of workers in the system when dishonest request
Magnetorheological (MR) fluid devices are widely used in active automotive control applications.However, MR fluid-based valve actuators are not in the limelight.This paper proposes a new flexible valve train with an MR fluid control system; the valve train can enhance the performance of internal crescent moon phase blade combustion engines.A major
