One set of partial dislocations bounding the APB cross-slips so that the APB lies on the low-energy plane, and, since this low-energy plane is not a permitted slip plane, the dissociated dislocation is now effectively locked.

This means that not only can it slow down neutrons to velocities in equilibrium with surrounding molecules (" thermalize " them and turn them into low-energy neutrons that are far more likely to interact with the Uranium-235 nuclei than the fast neutrons produced by fission initially ), but it can also absorb some of them outright.

Therefore, as widely recognized, existing low-energy bounds cannot be applied to high-energy phenomena ; however, many searches for Lorentz violation at high energies have been carried out using the Standard-Model Extension.

The gravitational field and the electromagnetic field are the only two fundamental fields in Nature that have infinite range and a corresponding classical low-energy limit, which greatly diminishes and hides their " particle-like " excitations.

Thus, although the current standard model of particle physics " in principle " predicts all known non-gravitational phenomena, in practice only a few quantitative results have been derived from the full theory ( e. g., the masses of some of the simplest hadrons ), and these results ( especially the particle masses which are most relevant for low-energy physics ) are less accurate than existing experimental measurements.

During a low-energy annihilation, photon production is favored, since these particles have no mass.

For instance, a cubic crystal may have low-energy planes on the faces of the cube or on the diagonals.

However, in the context of inflationary cosmology, different pocket universes may have different laws of low-energy physics operating in each of them.

All of the staffs appear to have a low-energy radar.

This causes b-jets to be wider, have higher multiplicities ( numbers of constituent particles ) and invariant masses, and also to contain low-energy leptons with momentum perpendicular to the jet.

Technical developments have been also conducted at RIKEN-RAL, but with a strongly reduced low-energy muons rate.

Rutherford had used strictly Newtonian methods to analyze the relatively low-energy alpha-scattering of this experiment.

Edward Belbruno of the Jet Propulsion Laboratory had been working for several years on numerically modelling low-energy ( weak stability boundary ) trajectories.

The berkelium-249 isotope emits low-energy electrons and thus is relatively safe to handle.

The original formulation of M-theory was in terms of a ( relatively ) low-energy effective field theory, called 11-dimensional Supergravity.

A positive corona generates much less ozone than the corresponding negative corona, as the reactions which produce ozone are relatively low-energy.

The planes are low-energy in the sense that if the crystal is cleaved along these planes, there will be relatively few broken bonds and a relatively small increase in energy over the unbroken crystal.

The relatively low-energy gamma from I-125 / Te-125 decay is poorly suited for imaging, but can still be seen, and this longer-lived isotope is necessary in tests which require several days of imaging, for example fibrinogen scan imaging to detect blood clots.

The scientific instruments consisted of an ion chamber and Geiger-Müller tube to measure total radiation flux, a proportional radiation counter telescope to measure high energy radiation, a scintillation counter to monitor low-energy radiation, a VLF receiver for natural radio waves, a transponder to study electron density, and part of the television facsimile system and flux-gate and search coil magnetometers mounted on the instrument platform.

The ability of larger macropods to survive on poor-quality, low-energy feed, and to travel long distances at high speed without great energy expenditure ( to reach fresh food supplies or waterholes, and to escape predators ) has been crucial to their evolutionary success on a continent that, because of soil fertility and low, unpredictable average rainfall, offers only very limited primary plant productivity.

The range of low-energy secondary electrons ( the largest component of the free electron population in the resist-substrate system ) which can contribute to charging is not a fixed number but can vary from 0 to as high as 50 nm ( see section New frontiers in electron beam lithography and extreme ultraviolet lithography ).

( Because of their high energy, gamma-ray photons are generally counted individually, whereas the lowest energy forms of EM radiation ( e. g., radio to sub-millimeter ) are observed as electromagnetic waves consisting of many low-energy photons.

In an effective field theory, all but the first few of the infinite set of parameters in a non-renormalizable theory are suppressed by huge energy scales and hence can be neglected when computing low-energy effects.

Over the last few years, Rexel has developed low-energy solutions ( lighting and high-performance motors ), as well as products using renewable energies, solar and wind power, geothermal and aerothermal energy ( heat pumps, solar water heaters and climate control solutions ).

Another variation is spin-polarized low-energy electron microscopy ( SPLEEM ), which is used for looking at the microstructure of magnetic domains.

Assigning oxygenated hemoglobin's oxidation state is difficult because oxyhemoglobin ( Hb-O < sub > 2 </ sub >), by experimental measurement, is diamagnetic ( no net unpaired electrons ), yet the low-energy electron configurations in both oxygen and iron are paramagnetic ( suggesting at least one unpaired electron in the complex ).

When a low-energy electron annihilates a low-energy positron ( antielectron ), they can only produce three or four gamma ray photons, since the electron and positron do not carry enough mass-energy to produce heavier particles and conservation of energy and linear momentum allow the creation of only one photon.

* Limiting energy usage and emissions from transportation ( walking, using bicycles or public transport, avoiding flying, using low-energy vehicles ), as well as from buildings, equipment, animals and processes.

* Similar to the approximate Lorentz symmetry of phonons in a lattice ( where the speed of sound plays the role of the critical speed ), the Lorentz symmetry of special relativity ( with the speed of light as the critical speed in vacuum ) is only a low-energy limit of the laws of Physics, which involve new phenomena at some fundamental scale.

In physics, this technique is referred to as PEEM, which goes together naturally with low-energy electron diffraction ( LEED ), and low-energy electron microscopy ( LEEM ).

The longer half-lived iodine-125 is also occasionally used when a longer half-life radioiodine is needed for diagnosis, and, in brachytherapy treatment ( isotope confined in small seed-like metal capsules ), where the low-energy gamma radiation without a beta component, makes iodine-125 useful.

In addition, unknown coupling constants, also called low-energy constants ( LECs ), are associated with terms in the Lagrangian that can be determined by fitting to experimental data or be derived from underlining theory.
