Charge pump with perfect current matching characteristics in phase-locked loops
Conventional CMOS charge pump circuits have some current mismatching characteristics. The current mismatch of the charge pump in the PLLs generates a phase offset, which increases spurs in the PLL… Expand
Optimistic bias about online privacy risks: Testing the moderating effects of perceived controllability and prior experience
This study examined the ways in which Internet users construct their risk judgments about online privacy. Expand
Collaborative Information Seeking in Intercultural Computer-Mediated Communication Groups
This article examines the process of collaborative information seeking in intercultural computer-mediated communication (CMC) groups and shows that preexisting social networks, groups, and intergroup boundaries significantly constrained the flow of information across intercultural CMC groups.

The influence of self-efficacy, subjective norms, and risk perception on behavioral intentions related to the H1N1 flu pandemic: A comparison between Korea and the US
This study examined the extent to which individualism-collectivism moderates the relative effects of agency control beliefs (i.e., self-efficacy), social norms (i.e., subjective norms), and risk… Expand
Simple and Task-oriented Mirror Therapy for Upper Extremity Function in Stroke Patients: A Pilot Study
Objective/Background To compare the effects of simple and task-oriented mirror therapies on upper extremity function in stroke patients with hemiplegia. Methods A single-subject, reversal (applied… Expand
A new one-step synthesis method for coating multi-walled carbon nanotubes with cuprous oxide nanoparticles
A new method was developed for the synthesis of Cu2O-coated multi-walled carbon nanotubes (MWCNTs) on the basis of Fehling’s reaction. The method involved dispersion of carbon nanotubes in Fehling’s… Expand
Giant strain in Nb-doped Bi0.5(Na0.82K0.18)0.5TiO3 lead-free electromechanical ceramics
Abstract The effect of Nb substitution on the crystal structure, ferroelectric, and electric field induced strain properties of Bi 0.5 (Na 82 K 0.18 ) 0.5 TiO 3 (BNKT) ceramics has been investigated.… Expand
