Heart rate is an essential vital sign to evaluate human health. Remote heart monitoring using cheaply available devices has become a necessity in the twenty-first century to prevent any unfortunate situation caused by the hectic pace of life. In this paper, we propose a new method based on the transformer architecture with a multi-skip connection biLSTM decoder to estimate heart rate remotely from videos.

- Driving behaviour analysis is increasingly important due to rising traffic accidents, linking driver state with driving environment and actions.
- The paper investigates the relationship between drivers' vital signs (like heart rate and blood pressure), eye state, head pose, vehicle maneuvers, and external events, utilizing advanced models and synchronized video datasets.
- Results show weak correlations between certain driver states (heart rate, blood pressure) and specific driving actions (maneuvers, overtaking), along with some significant correlations between head movement and driving events.
Article Synopsis
- Blood pressure is a critical health indicator, often measured using expensive and inconvenient cuff-based methods, but new studies show that changes in skin color related to blood flow can help estimate it.
- Researchers propose a novel method using deep learning to analyze face videos, leveraging data from the Vision for Vitals dataset to validate their approach.
- They introduced a new performance metric based on the correlation between estimated blood pressure and respiratory rates, offering a fast and comfortable cuff-less solution that only requires a smartphone camera.
Meditation practice is mental health training. It helps people to reduce stress and suppress negative thoughts. In this paper, we propose a camera-based meditation evaluation system, that helps meditators to improve their performance.

Aim: The aim of the present study was to highlight the occurrence of hepatitis E viraemia by nested reverse transcriptase polymerase chain reaction (RT-PCR) in patients with acute on chronic liver failure.
