Effect of body composition methodology on heritability estimation of body fatness [PDF]
, 2012 Heritability estimates of human body fatness vary widely and the contribution of body composition methodology to this variability is unknown. The effect of body composition methodology on estimations of genetic and environmental contributions to body ...

Mixer-First Receiver with wide-RF Range [PDF]
arXiv, 2019 In the Passive Mixer first receiver, four mosfet, and four baseband impedance can synthesize High-Q bandpass filter. This on-chip High-Q bandpass filter can replace bulky, expensive and off-chip SAW filters. The impedance which is seen by the antenna is tuned by switch resistance of the Passive Mixer and the input impedance of the Trans-impedance ...

The Leontovich boundary conditions and calculation of effective impedance of inhomogeneous metal [PDF]
, 2001 We bring forward rather simple algorithm allowing us to calculate the effective impedance of inhomogeneous metals in the frequency region where the local Leontovich (the impedance) boundary conditions are justified. The inhomogeneity is due to the properties of the metal or/and the surface roughness. Our results are nonperturbative ones with respect to

Safe Online Gain Optimization for Variable Impedance Control [PDF]
arXiv, 2021 Smooth behaviors are preferable for many contact-rich manipulation tasks. Impedance control arises as an effective way to regulate robot movements by mimicking a mass-spring-damping system. Consequently, the robot behavior can be determined by the impedance gains.

Durability as an index of endurance exercise performance: Methodological considerations
Experimental Physiology, EarlyView.Abstract Endurance athletes routinely complete physiological assessments to predict performance, inform training programmes and monitor subsequent training adaptations. This profiling is typically performed with the athlete in a ‘fresh’ (i.e., rested) condition, but physiological profiling variables deteriorate during prolonged exercise. Durability has

Quality-based Pulse Estimation from NIR Face Video with Application to Driver Monitoring [PDF]
arXiv, 2019 In this paper we develop a robust for heart rate (HR) estimation method using face video for challenging scenarios with high variability sources such as head movement, illumination changes, vibration, blur, etc. Our method employs a quality measure Q to extract a remote Plethysmography (rPPG) signal as clean as possible from a specific face video ...

The therapeutic role of exercise training during menopause for reducing vascular disease
Experimental Physiology, EarlyView.Abstract Menopause marks a major milestone in female reproductive ageing. It is characterized by the cessation of ovarian function and a concomitant decline in hormones such as oestradiol. Subsequently, females undergoing menopausal transition experience a progressive increase in cardiovascular and cerebrovascular disease risk.

Efficient Real-Time Camera Based Estimation of Heart Rate and Its Variability [PDF]
arXiv, 2019 Remote photo-plethysmography (rPPG) uses a remotely placed camera to estimating a person's heart rate (HR). Similar to how heart rate can provide useful information about a person's vital signs, insights about the underlying physio/psychological conditions can be obtained from heart rate variability (HRV).
