Systematic Studies of the Circadian Clock Genes Impact on Temperature Compensation and Cell Proliferation Using CRISPR Tools

Biology, 2021
Mammalian circadian genes are capable of producing a self-sustained, autonomous oscillation whose period is around 24 h. One of the major characteristics of the circadian clock is temperature compensation.

Handling Ambient Temperature Changes in Correlative Thermal Error Compensation

Journal of Machine Engineering, 2023
Thermal errors are one of the lead causes for positioning inaccuracies in modern machine tools. These errors are caused by various internal and external heat sources and sinks which shape the machine tool’s temperature field and thus its deformation ...

Design of Temperature Compensation Circuit to Compensate Temperature Characteristics of VCO [PDF]

The Journal of Korean Institute of Electromagnetic Engineering and Science, 2010
In this paper, temperature compensation circuit for the X-band voltage controlled oscillator(VCO) is presented by using the temperature sensor with the OP-AMP circuit. The frequency drifting by the temperature could be compensated by applying the tuning voltage which include the linearly changing output voltage of the temperature sensor.
