Area under an ROC curve plays an important role in estimating discrimination performance – a well-known theorem by Green (1964) states that ROC area equals the percentage of correct in two-alternative forcedchoice setting. When only single data point is available, the upper and lower bound of discrimination performance can be constructed based on the maximum and minimum area of legitimate ROC c...

Masked autoencoding has achieved great success for self-supervised learning in the image and language domains. However, mask based pretraining yet to show benefits point cloud understanding, likely due standard backbones like PointNet being unable properly handle training versus testing distribution mismatch introduced by masking during training. In this paper, we bridge gap proposing a discrim...

Saccadic and manual responses were used to investigate the speed of discrimination between happy and non-happy facial expressions in two-alternative-forced-choice tasks. The minimum latencies of correct saccadic responses indicated that the earliest time point at which discrimination occurred ranged between 200 and 280ms, depending on type of expression. Corresponding minimum latencies for manu...

DESIGN A cross-sectional case-control study. SETTING Laboratory-based study. PARTICIPANTS Nineteen chronic non-specific low back pain patients and 19 healthy controls. MAIN OUTCOME MEASURES Tacti...

INTRODUCTION The purpose of this study was to comparatively evaluate the clinical outcomes of open carpal tunnel release with or without flexor tenosynovectomy and epineurectomy for the treatment of idiopathic carpal tunnel syndrome. METHODS In this prospective single-blinded study, 61 wrists of 47 patients randomized to open carpal tunnel release without (Group-1) or with (Group-2) flexor te...

BACKGROUND  Reconstruction of complex soft tissue defects of the thumb, with exposure of tendons, joints or bones, has always been a difficult task. We evaluated the functional and esthetic outcomes of 1st dorsal metacarpal artery island flap in reconstruction of post-traumatic soft tissue defects of the thumb. METHODS Between January 2012 and June 2014, fifteen patients with co...
