Typical pulse as measured with THz-TDS. In physics, terahertz time-domain spectroscopy (THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation.

Traces is a British television crime drama produced by Red Production Company (a StudioCanal company). Co-created and written by Val McDermid and Amelia Bullmore , and based upon an original idea by McDermid, it originally premiered on Alibi on 9 December 2019.
Temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When experiments are performed using well-defined surfaces of single-crystalline samples in a continuously pumped ultra-high vacuum (UHV) chamber, then this experimental technique is often also referred to as thermal desorption spectroscopy or thermal ...
Tr ω (T) is linear in T.; If T ≥ 0 then Tr ω (T) ≥ 0; If S is bounded then Tr ω (ST) = Tr ω (TS); Tr ω (T) does not depend on the choice of inner product on H.; Tr ω (T) = 0 for all trace class operators T, but there are compact operators for which it is equal to 1.
In the English language, nigger is a racial slur directed at black people.Starting in the 1990s, [1] references to nigger have been increasingly replaced by the euphemism "the N-word", notably in cases where nigger is mentioned but not directly used. [2]
