Efficient localization of a native metal ion within a protein by Cu2+-based EPR distance measurements.

Physical Chemistry, Chemical Physics - PCCP, 2019
Electron paramagnetic resonance (EPR) based distance measurements have been exploited to measure protein-protein docking, protein-DNA interactions, substrate binding and metal coordination sites.

Distance measuring device for acoustically measuring distance

The Journal of the Acoustical Society of America, 2008
A distance measuring device includes a transmitter for transmitting an acoustic signal at a distant object, an acoustic signal receiver for receiving a reflected acoustic signal reflected from the distant object, a temperature sensor detecting air temperature, a humidity sensor detecting air humidity, an amplifier amplifying the reflected acoustic ...

A Reactive, Rigid GdIII Labeling Tag for In-Cell EPR Distance Measurements in Proteins.

Angewandte Chemie, 2017
The cellular environment of proteins differs considerably from in vitro conditions under which most studies of protein structures are carried out. Therefore, there is a growing interest in determining dynamics and structures of proteins in the cell.

Evaluating linguistic distance measures

Physica A: Statistical Mechanics and its Applications, 2010
In Ref. [13], Petroni and Serva discuss the use of Levenshtein distances (LD) between words referring to the same concepts as a tool for establishing overall distances among languages which can then subsequently be used to derive phylogenies. The authors modify the raw LD by dividing the LD by the length of the longer of the two words compared, to ...

Distance-Distance Method for Straightness Measurement

CIRP Annals, 1992
Abstract A new method for straightness measurement based on distance measurement from two reference points is introduced in this paper. “he distinguishing feature of this method is that it does not require a straightness reference. It gives high accuracy due to high accuracy in displacement measurement.

The measurement of distance

Australian Surveyor, 1973
Abstract Radical changes in the technique of distance measurement followed the introduction of long steel ribands, made possible in 1863 by Chesterman's patented process of treating continuous steel strip. Gunter's linked chains, which had been in use for over 250 years, were replaced by steel tapes up to 10 chains in length, with dramatic improvements

Measuring Cosmic Distances

2021
The astronomical unit (AU) was first used in ancient Greece after Pythagoras had developed geometry. Although they could not measure the distance from the Earth to the Sun, the Greeks could use the relationships of the angles and sides of a right triangle to determine the distance of Venus or Mercury from the Sun as a function of the Earth–Sun distance,

Electromagnetic Distance Measurement

1978
The direct method of distance measurement discussed in chapter 1 has the disadvantage that measurements over unsuitable terrain or on congested sites can be very difficult and, in some cases, impossible. This problem was overcome with the development of optical distance measurement techniques (see chapter 6) but, in general, such methods are only ...
