Efficacy and Safety of Electroacupuncture Through Nerve Stimulation in Patients With Anxiety Disorders: Protocol for a Randomized, Assessor-Blind, Three-Arm, Parallel-Group Clinical Trial

Efficacy and Safety of Electroacupuncture Through Nerve Stimulation in Patients With Anxiety Disorders: Protocol for a Randomized, Assessor-Blind, Three-Arm, Parallel-Group Clinical Trial

Facial expressions will be analyzed using i Motion software (i Motions A/S). The electrocardiography signal will be recorded using electrodes placed on the participant’s chest. Heart rate and R-R intervals will be extracted from the electrocardiography data using an in-house script developed in MATLAB (2016b, The Math Works, Inc). The time-domain HRV metrics will include the mean R-R interval, the SD of R-R interval, and the root-mean-square of successive differences.

Hand Motion Control Ability Between Young and Older Adults: Comparative Study

Hand Motion Control Ability Between Young and Older Adults: Comparative Study

One full rotation includes 180° in each direction (total 360°), measured over 30 frames (~0.03 s per frame). Experiment setting. This figure shows the experimental setup for the comparative study on hand movement control abilities between younger and older adults. In the experiment, participants sat facing the webcam, and upon the appearance of a "recording" sign on the screen, they were instructed to perform hand rotation movements with both hands as quickly and accurately as possible for 10 seconds.

A Comprehensive Profiling System Integrating Myers-Briggs Type Indicator (MBTI) and Dominance, Influence, Steadiness, and Conscientiousness (DISC) for Personalized Health Training: Correlational Analysis and Usability Evaluation

A Comprehensive Profiling System Integrating Myers-Briggs Type Indicator (MBTI) and Dominance, Influence, Steadiness, and Conscientiousness (DISC) for Personalized Health Training: Correlational Analysis and Usability Evaluation

DISC categorizes human behavioral styles into 4 types: Dominance (D) for goal-oriented and challenging individuals; Influence (I) for optimistic and social people; Steadiness (S) for calm and patient individuals; and Conscientiousness (C) for analytical and logical thinkers. MBTI explains psychological preferences in perceiving and judging the world through 4 dichotomies.

Detection and Analysis of Circadian Biomarkers for Metabolic Syndrome Using Wearable Data: Cross-Sectional Study

Detection and Analysis of Circadian Biomarkers for Metabolic Syndrome Using Wearable Data: Cross-Sectional Study

In Equation 4, N is the total number of measured time data, S is the number of data per day, and x-his the hourly mean. The numerator represents the squared deviations of the hourly means from the overall mean, whereas the denominator reflects the total variance of the entire series. As the ratio of these 2 terms increases, the IS value becomes larger, and activity patterns that recur at identical clock times on successive days yield higher IS values.
