Alexander A. Borbély (born 1939 in Budapest) is a Hungarian-Swiss pharmacologist known for his sleep research.. Borbély proposed the two-process model of sleep regulation in 1982 which postulates there are two complementary processes (S and C, which stands for Sleep and Circadian, respectively) which together account for one's sleep schedule. [1]
In 1993, a different model called the opponent process model [98] was proposed. This model explained that these two processes opposed each other to produce sleep, as against Borbely's model. According to this model, the SCN, which is involved in the circadian rhythm, enhances wakefulness and opposes the homeostatic rhythm.
This model proposes a homeostatic process (Process S) and a circadian process (Process C) that interact to define the time and intensity of sleep. [71] Process S represents the drive for sleep, increasing during wakefulness and decreasing during sleep until a defined threshold level, while Process C is the oscillator responsible for these levels.

Dijk's research focusses on the regulation and function of sleep and its interaction with the circadian timing system in humans. [8] He examines how sleep, sleep regulation and circadian rhythms change across the lifespan and how sleep and circadian rhythms are affected by environmental factors such as natural and artificial light.

A urine sensor is a necessary part of any bedwetting alarm. A basic urine sensor consists of two electricity conductors separated by moisture absorbing insulating material. A low DC electric voltage, provided by batteries, is applied across these conductors. This low voltage is usually about 3 volts, so as not to be dangerous to the user.
Emotions play a key role in overall mental health, [1] and sleep plays a crucial role in maintaining the optimal homeostasis of emotional functioning. [2] [3] Deficient sleep, both in the form of sleep deprivation and restriction, adversely impacts emotion generation, emotion regulation, and emotional expression. [4]
