Three‐ to 4‐year follow‐up of the reverse palatal pedicle graft for maxillary palatal recessions

Clinical Advances in Periodontics, Volume 15, Issue 3, Page 255-262, September 2025.
Abstract Background This study evaluates the long‐term stability and clinical outcomes of the reverse palatal pedicle graft (RPPG) technique in treating maxillary molar palatal recessions over a 3 to 4‐year follow‐up period. Methods Three patients with palatal recession defects on maxillary molars were treated using the RPPG technique.

Evaluating RGB channels in remote photoplethysmography: a comparative study with contact-based PPG

Frontiers in Physiology, 2023
Remote photoplethysmography (rPPG) provides a non-contact method for measuring blood volume changes. In this study, we compared rPPG signals obtained from video cameras with traditional contact-based photoplethysmography (cPPG) to assess the ...

Layer‐Wise Cue Alignment for Unified Face Attack Detection With Vision‐Language Model

IET Biometrics, Volume 2025, Issue 1, 2025.
Unified face attack detection (UAD), which simultaneously addresses physical presentation attacks (PAs) and digital forgery attacks (DAs) with a vision‐language model, remains challenging due to the difficulty of effectively separating live and fake cues.

The angular momentum of two collided rarefied preplanetesimals and the formation of binaries

, 2009
This paper studies the mean angular momentum associated with the collision of two celestial objects in the earliest stages of planet formation. Of primary concern is the scenario of two rarefied preplanetesimals (RPPs) in circular heliocentric orbits ...

Facial Emotion Recognition Method Based on Convolutional Neural Network

IET Computers &Digital Techniques, Volume 2025, Issue 1, 2025.
Facial emotion recognition has poor robustness and low recognition accuracy in complex lighting, posture changes, and occlusion scenes. This study aims to design a high‐performance convolutional neural network (CNN) model to improve the recognition accuracy and generalization ability of seven basic emotions in complex environments.

rPPG-SysDiaGAN: Systolic-Diastolic Feature Localization in rPPG Using Generative Adversarial Network with Multi-domain Discriminator

Remote photoplethysmography (rPPG) offers a novel approach to noninvasive monitoring of vital signs, such as respiratory rate, utilizing a camera. Although several supervised and self-supervised methods have been proposed, they often fail to accurately reconstruct the PPG signal, particularly in distinguishing between systolic and diastolic components.
