Stress is a natural human reaction to demands or pressure, usually when perceived as harmful or/and toxic. When stress becomes constantly overwhelmed and prolonged, it increases the risk of mental health physiological uneasiness. Furthermore, chronic raises likelihood plagues such anxiety, depression, sleep disorder. Although measuring using parameters heart rate variability (HRV) common approach, how achieve ultra-high accuracy based on HRV measurements remains challenging task. not...

Automatic e-coaching may motivate individuals to lead a healthy lifestyle with early health risk prediction, personalized recommendation generation, and goal evaluation. Multiple studies have reported on uninterrupted automatic monitoring of behavioral aspects (such as sedentary time, amount, type physical activity); however, feedback techniques are still in nascent stage. Current intelligent coaching strategies mostly based the handcrafted string messages that rarely individualize each...

Hawking radiation from a non-extremal black hole is known to be approximately Planckian. The thermal spectrum receives multiple corrections including greybody factors and due kinematical restrictions on the infrared ultraviolet frequencies. We show that another significant correction arises if assumed live in bath emitted gets thermalised at temperature. This modification reshapes spectrum, leads appreciable deviation standard results decay rate of holes. argue this altered has significance...
