Type Synthesis of 3R2T Hybrid Robot Mechanisms based on Serial-opened-chain Unit
Published 2015-01-01“…Firstly,type synthesis of 3T2 R 5- DOF serial mechanism with single- opened- chain is classified based on the screw theory,then the type synthesis of 3T2 R hybrid mechanisms are accomplished by regarding parallel mechanism as a complex kinematic unit and replacing an equal DOF kinematic chain limb in lower- mobility serial mechanism with single- opened- chain limb. …”

Development and application of a lightweight five-axis parallel machining robot
Published 2021-09-01“…In the fields of national defense, aerospace, and energy, there exist plenty of complex surface core parts, for example, the aircraft structural components and turbine blades.These parts usually have the machining requirements of large material removal rate, high dimensional accuracy and high surface quality.The traditional five-axis serial machine centers face two problems in the machining process: (1) the tool will automatically rotate when it passes through the pole posture; (2)the driving axes’dynamic response does not match.It was tried to solve these problems from the view of machining equipments’ configuration.By making fully use of the advantages of parallel robots in compact structure, high stiffness, kinematic flexibility and dynamic response, a lightweight five-axis parallel machining robot with attitude coupling motion and uniform driving axes’ dynamic response was developed.The optimal design, motion control, and precision guarantee were carried out to realize the high-efficiency and high-quality machining of complex curved parts.Finally, the application verification in AVIC (Aviation Industry Corporation of China) Chengdu Aircraft Industrial (Group) Co., Ltd.was conducted.…”

Alterations of attention and impulsivity in the rat following a transgenerational decrease in dietary omega-3 fatty acids
Published 2018-03-01“…The male offspring of these three diet groups were tested using an established paradigm for the assessment of attention and impulsive behavior, i.e. a modified version of the five-choice-serial-reaction-time task (5CSRTT). The present data show that the deficiency of omega-3 PUFAs over generations led to substantial changes in attentional processes and impulsive behaviors. …”

Changes in faecal haemoglobin values over sequential rounds of faecal immunochemical tests (FIT) in a surveillance population
Published 2025-02-01“…Participants were grouped based on changes between FIT rounds, with changes defined as absolute differences ≥4 µg/g, and positivity at round 3.Results Among 4412 participants, the largest group (n=2773) was the no change category, which had the lowest ACN detection rate (4.7%, 95% CI: 3.9 to 5.5). The serial increase group with a positive round 3 value (n=46) had the highest ACN detection rate (32.6%, 95% CI: 19.5 to 48.0).Conclusion No change in FIT result across multiple rounds was associated with a low ACN detection rate, while a serial increase was associated with higher ACN detection rates. …”
