Face Tracking Based on 3D Positional Hypothesis
2009 Seventh International Conference on Advances in Pattern Recognition, 2009Probabilistic and statistical model analysis methods based on the Bayesian approach have recently been applied to face tracking. Here, we propose a face tracking method based on a Bayesian framework of image sequences. We assume that an observed space is three-dimensional (3D) and model facial shape, rotation and translation in 3D.

Positive Parenting Matters in the Face of Early Adversity
American Journal of Preventive Medicine, 2019A negative relationship between adverse childhood experiences and both physical and mental health in adulthood is well established, as is the positive impact of parenting on child development and future health. However, few studies have investigated unique influences of adverse childhood experiences and positive parenting together within a large ...

Positive-Unlabeled Learning in the Face of Labeling Bias
2015 IEEE International Conference on Data Mining Workshop (ICDMW), 2015Positive-Unlabeled (PU) learning scenarios are a class of semi-supervised learning where only a fraction of the data is labeled, and all available labels are positive. The goal is to assign correct (positive and negative) labels to as much data as possible.

A Positive Answer to Bárány’s Question on Face Numbers of Polytopes
Combinatorica, 2023Despite a full characterization of the face vectors of simple and simplicial polytopes, the face numbers of general polytopes are poorly understood. Around 1997, Bárány asked whether for all convex $d$-polytopes $P$ and all $0 \leq k \leq d-1$, $f_k(P) \geq \min\{f_0(P), f_{d-1}(P)\}$. We answer Bárány's question in the affirmative and prove a stronger

Hemispheric Differences in the Perception of Positive and Negative Faces
International Journal of Neuroscience, 1985Thirty-two right-handed subjects (15 males and 17 females) participated in a study investigating the effects of the perception of positive and negative emotional stimuli on choice reaction time. Slides of faces showing positive (happy, surprise) or negative (anger, disgust, sadness) affect were presented via a tachistoscope to either the right or left ...

Continuous Positive Airway Pressure (CPAP) by Face Mask
Survey of Anesthesiology, 1980The authors studied the use of CPAP by face mask in 44 patients with mild to moderate acute respiratory insufficiency (mean PaO2/FIO2 = 171 +/- 42 (SD). All patients improved their oxygenation (mean PaO2/FIO2 = 300 +/- 68 (SD) after the application of CPAP (mean 9 +/- 3 (SD) cm H2O). One patient developed a respiratory acidemia and was intubated.

Face Tissue Pressures in Prone Positioning
Journal of Spinal Disorders & Techniques, 2008Pilot Study.The objective of this study was to compare face tissue pressures for 3 different prone head positioners in healthy, conscious individuals in the prone position.The incidence of intraoperatively acquired pressure ulcers has been reported to range from 12% to 66%; healthcare literature lacks information about lesions specific to the face ...
