Attenuation involves deleting viral genes, or gene regions, to eliminate viral functions that are expendable in tumour cell, but not in normal cells.

Attenuation in ultrasound is the reduction in amplitude of the ultrasound beam as a function of distance through the imaging medium.

Attenuation coefficients vary widely for different media.

Attenuation due to scattering of ultrasonic compressional waves in granular media-A. J.

Attenuation of the gamma rays within the patient can lead to significant underestimation of activity in deep tissues, compared to superficial tissues.

Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam ( or signal ) with respect to distance traveled through a transmission medium.

Attenuation coefficients in fiber optics usually use units of dB / km through the medium due to the very high quality of transparency of modern optical transmission media.

Attenuation is an important factor limiting the transmission of a signal across large distances.

Attached to the muzzle of the weapon is the Blast Attenuation Device ( BAD ), used to reduce the blast effects on the mortar crew.

Attenuation of these spurious emissions is usually done with a band-pass filter, tuned to allow through the correct center frequency of the carrier wave, as well as all necessary sidebands.

At these velocities, the correction factors derived using linearized theory breaks down due to a singularity that occurs at a Mach number of 1.

This feature of the visual system is called chromatic adaptation, or color constancy ; when the correction occurs in a camera it is referred to as white balance.

Next, Cardwell noted that bearish divergence: 1 ) only occurs in uptrends, and 2 ) mostly only leads to a brief correction instead of a reversal in trend.

For example, a positive reversal occurs when an uptrend price correction results in a higher low compared to the last price correction, while RSI results in a lower low compared to the prior correction.

Light-time correction occurs in principle during the observation of any moving object, because the speed of light is finite.

Once presbyopia occurs, those who are emmetropic ( do not require optical correction for distance vision ) will need an optical aid for near vision ; those who are myopic ( nearsighted and require an optical correction for distance vision ), will find that they see better at near without their distance correction ; and those who are hyperopic ( farsighted ) will find that they may need a correction for both distance and near vision.

This only occurs for the 1-loop correction, therefore the contribution of the Majorana fermions to the Chern – Simons level may be precisely calculated at 1-loop and all higher loop corrections vanish.

In the theory, a correction or " credit crunch " – commonly called a " recession " or " bust " – occurs when exponential credit creation cannot be sustained.

The shame and guilt this method induced, he believed, was far superior to the fear instilled by corporal punishment ; when he used physical " correction " he required that the students be unanimously in support of its application, even including the student to be punished.

Light-time correction does not depend on the motion of the Earth – it only depends on Earth's position at the instant when the light is observed.

Aberration is usually larger than a planet's light-time correction except when the planet is near quadrature ( 90 ° from the Sun ), where aberration drops to zero because then the Earth is directly approaching or receding from the planet.

Spencer Jones ' work of 1939 showed that the positions of the Sun actually observed, when compared with those obtained from Newcomb's formula, show the need for the following correction to the formula to represent the observations:

# A pre-bolus of insulin can combine a meal bolus and a correction bolus when the blood sugar is above the target range before a meal.

This is particularly useful when correcting for a high blood sugar as the meter remembers readings and automatically enters them in correction boluses if they are less than 15 minutes old.

Some audio formats feature a combination of a lossy format and a lossless correction which when combined reproduce the original signal ; the correction can be stripped, leaving a smaller, lossily compressed, file.

If adding that detail only altered things slightly then it would not have been too bad, but disaster struck when it was found that the simple correction mentioned above led to infinite probability amplitudes.

It was a big breakthrough for the theory of quantum information, when quantum error correction codes and fault-tolerant quantum computation schemes were discovered.

Perspective correction lenses are available in the 35 mm and medium formats to correct this distortion with film cameras, and it can also be corrected after the fact with photo software when using digital cameras.

However, construction and growth slowed when the housing bubble burst in 2007, resulting in a housing market correction.

In 1998, Lyster concluded that “ recasts ” ( when the teacher repeats a student ’ s incorrect utterance with the correct version ) are not always the most useful because students do not notice the correction ( Russell, 2009 ).

All Minox cameras except the EC has parallax correction viewfinder, when the focusing dial moves, the viewfinder moves in tandem to correct for parallax.

If the standard stars cannot be observed simultaneously with the target ( s ), this correction must be done under photometric conditions, when the sky is cloudless and the extinction is a simple function of the airmass.

Positioned above the atmosphere, Hubble avoids atmospheric airglow allowing it to take more sensitive visible and ultraviolet light images than can be obtained with seeing-limited ground-based telescopes ( when good adaptive optics correction at visible wavelengths becomes possible, 10 m ground-based telescopes may become competitive ).
