The immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs). Cells may be unhealthy because of infection or because of cellular damage caused by non-infectious agents like sunburn or cancer.he immune system can distinguish between normal, healthy cells and unhealthy cells by recognizing a variety of danger cues called danger-associated molecular patterns (DAMPs).

Time-weighted return. The time-weighted return (TWR) (or true time-weighted rate of return (TWRR)) is a method of calculating investment return. To apply the time-weighted return method, combine the return over sub-periods, by compounding them together, resulting in the overall period return. The rate of return over each different sub-period is weighted according to the duration of the sub-period.
An object that is set to today's date, with the time component set to 00:00:00. Starting with the .NET Framework version 2.0, the return value is a DateTime whose Kind property returns Local. Because it returns the current date without the current time, the property is suitable for use in applications that work with dates only.
