T wave is considered flat when the wave varies from -1.0 mm to + 1.0 mm in height. Hypokalemia or digitalis therapy can cause flattened T wave with a prominent U wave. As hypokalemia progressively worsens, the T wave becomes more flattened while the U wave becomes more prominent, with progressively deeper ST segment depression.
The U band is a range of frequencies contained in the microwave region of the electromagnetic spectrum. Common usage places this range between 40 and 60 GHz , but may vary depending on the source using the term.
The U wave is a wave on an electrocardiogram (ECG). It comes after the T wave of ventricular repolarization and may not always be observed as a result of its small size. 'U' waves are thought to represent repolarization of the Purkinje fibers. [1] [2] However, the exact source of the U wave remains unclear. The most common theories for the ...
A "high frequency gravitational wave generator" that may be used "for advanced propulsion, asteroid disruption and/or deflection, and communications through solid objects."(2017). [ 18 ] Testing on the feasibility of a High Energy Electromagnetic Field Generator (HEEMFG) occurred from October 2016 to September 2019; at a total cost of $508,000 ...

Animation of two waves, the green wave moves to the right while blue wave moves to the left, the net red wave amplitude at each point is the sum of the amplitudes of the individual waves. Note that f(x, t) + g(x, t) = u(x, t). in the direction in space.
The term T-wave may refer to: T wave, a portion of the recording of a heartbeat in an electrocardiogram; Terahertz radiation, electromagnetic radiation in the microwave band; T wave (seismic), a form of seismic wave
