From a basis in social exchange theory, the authors investigated whether, and how, negative feedback-seeking behavior and a team empowerment climate affect the relationship between leader-member exchange (LMX) and member performance. Results showed that subordinates' negative feedback-seeking behavior mediated the relationship between LMX and both objective… (More)
Enterprise-scale organizations have large numbers of internal and external users, with different privilege requirements spanning across many resources. The dynamic nature of modern organizations demands that they efficiently and securely provision and deactivate data privileges to reflect rapidly changing user responsibilities. Previous approaches to… (More)
PURPOSE Construct subsidence is a relatively common complication following anterior cervical fusion. Its occurrence has been revealed to be closely related to endplate-implant contact interface. But current literature focusing on the anatomy of cervical endplate is very scarce. The purpose of this morphometric study was to analyse the sagittal geometry,… (More)

Surface deformation and fracture processes of materials under external force are important for understanding and developing materials. Here, a combined horizontal universal mechanical testing machine (HUMTM)-atomic force microscope (AFM) system is developed by modifying UMTM to combine with AFM and designing a height-adjustable stabilizing apparatus. Then… (More)
Sharing data containing sensitive information, such as medical records, always has privacy and security implications. In situations such as health environments, accurate individual data needs to be provided while at the same time, mass data release for medical research may also be required. This paper outlines a solution for maintaining the privacy of data… (More)
This paper describes a robust and simple algorithm for fetal electrocardiogram (FECG) estimation from abdominal signal using adaptive comb filter (ACF). The ACF can adjust itself to the temporal variations in fundamental frequency, which makes it qualified for the estimation of quasi-periodic component from physiologic signal, such as ECG. The validity and… (More)
