Impact of individual differences in glucocorticoid adaptation to stress on behavior, neurophysiology and metabolism

The stress system is a key modulator of homeostasis and allows organisms to adapt to environmental changes. Proper survival is dependent on the appropriate stress response, for example initiating food (energy) intake or provoking physical reaction. However ...

Perceived interest and heart rate response to façade and daylight patterns in Virtual Reality

Marilyne Andersen, Jan Wienold, Giorgia Chinazzo, Kynthia Chamilothori, João Pedro de Matos Rodrigues

This contribution introduces an experimental study aiming to provide concrete evidence on how façade and daylight pattern geometry can affect the emotional responses triggered by a space. The study was conducted in Virtual Reality (VR) where participants w ...

Implantable IoT System for Closed-Loop Epilepsy Control based on Electrical Neuromodulation

Alexandre Schmid, Reza Ranjandish

A closed-loop system aiming at epilepsy control is proposed in this paper, in which electrical stimulation is triggered upon a decision aggragating different biological signatures of the seizure such as changes in the heart rate, blood flow in the brain, a ...

Submaximal exercise testing at low altitude for prediction of exercise tolerance at high altitude

Johannes Burtscher

Annually, thousands of air travellers visit high altitude destinations to enjoy hiking tours to attractions in surrounding areas. However, many of them are not adequately trained, not sufficiently acclimatized and/or may suffer from pre-existing diseases. ...

Robust Baseline Measurement for Reliable Fetal Heart Rate Evaluation

Guglielmo Frigo

Cardiotocography is a measurement technique widely adopted to assess fetal well-being during both antepartum and intra-partum stages. It consists of two simultaneously acquired time-series: fetal heart rate and uterine activity. Since visual inspection ana ...

Jointly Learning Energy Expenditures and Activities using Egocentric Multimodal Signals

Alexandre Massoud Alahi

Physiological signals such as heart rate can provide valuable information about an individual’s state and activity. However, existing work on computer vision has not yet explored leveraging these signals to enhance egocentric video understanding. In this w ...

A Hybrid CDAC-Threshold Configuring SAR ADC in 28nm FDSOI CMOS

Mustafa Kilic, Yusuf Leblebici, Themistoklis Mavrogordatos

In this paper, a 9-bit 1.3 GS/s single channel SAR ADC is presented. In conventional SAR ADCs, the capacitive DAC size grows exponentially with respect to converter resolution. This results in both signal bandwidth and conversion speed reduction. The propo ...
