However, since energy detection is inherently " square-law " detection, it intrinsically mixes any optical frequencies present on the detector.

However optical pulse width and signal integration time are user adjustable, and require trade-offs which make them application specific.

However, satellite data show that cloud optical thickness actually increases with increasing temperature .< ref name = tselioudis-1992 > Whether the net effect is warming or cooling depends on details such as the type and altitude of the cloud ; details that are difficult to represent in climate models.

However, sliding contacts wear out and need maintenance, which favors optical encoders.

However, any two pairs of conjugate states can be used for the protocol, and many optical fibre based implementations described as BB84 use phase encoded states.

However, Orliac ( 2005 ) examined seven objects ( tablets B, C, G, H, K, Q, and reimiro L ) with stereo optical and scanning electron microscopes and determined that all were instead made from Pacific rosewood ( Thespesia populnea ); the same identification had been made for tablet M in 1934.

However, dispersion also has an effect in many other circumstances: for example, GVD causes pulses to spread in optical fibers, degrading signals over long distances ; also, a cancellation between group-velocity dispersion and nonlinear effects leads to soliton waves.

However, photonics covers a huge range of science and technology applications, including: laser manufacturing, biological and chemical sensing, medical diagnostics and therapy, display technology, and optical computing.

However, searching for terrestrial planets in the optical / near infrared has the advantage that the diffraction limit corresponds to a smaller angle for a given size telescope.

However, the use of fluorescence allowed FMDs to operate according to the principles of 3D optical data storage and have up to 100 data layers.

However, very good results can be obtained only with a flash unit that is separated from the camera, sufficiently far from the optical axis, or by using bounce flash, where the flash head is angled to bounce light off a wall, ceiling or reflector.

However, the system is designed, ingeniously and hopefully, so that no one man could initiate a thermonuclear war.

However, it cannot be presumed, informal though the structure of the population seems, that there are not well-defined roles within the system.

However a comparable performing digital system is more complex and can require more bandwidth than its analog counterpart.

However, physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone.

However, the Mobile River system has a high incidence of endemism among freshwater mollusks and biodiversity is high.

However, an important mode of transportation is the government subsidized ' Colectivo ' cab system.

However, he thinks that these too occur out of necessity since an outside observer can see the same regularity that he would in a purely physical system.

However the original kit version lacked many features that prevented its use as a serious computer system.

However, although Apollonius came close to developing analytic geometry, he did not manage to do so since he did not take into account negative magnitudes and in every case the coordinate system was superimposed upon a given curve a posteriori instead of a priori.

However, his construction of the Gothic alphabet is based upon an entirely different modular system.

However, there is limited evidence that mistletoe's effects on the immune system help the body fight cancer .... At present, the use of mistletoe cannot be recommended outside the context of well-designed clinical trials.

However, shortly after this positive result, Kurt Gödel published On Formally Undecidable Propositions of Principia Mathematica and Related Systems ( 1931 ), showing that in any sufficiently strong axiomatic system there are true statements which cannot be proved in the system.

However, the defining recommendation indicates a change to a system similar to ISO 8601 and astronomical year numbering is likely in the future.

However, as the system was reaching completion, the personal computer revolution was starting with the release of machines like the Commodore PET, TRS-80 and Apple II.

However, the game system was reviewed in 1990 in Dragon # 155 by Hartley, Patricia, and Kirk Lesser in " The Role of Computers " column.

However infection at an intermediate stage, before the fetal immune system is fully developed, may result in a chronic infection that lingers until the first months after birth of the lamb.

However, Thomas Cavalier-Smith rejects the three-domain system and places the Archaea as a subkingdom of Bacteria.

However, they are much less toxic than their predecessors, the barbiturates, and death rarely results when a benzodiazepine is the only drug taken ; however, when combined with other central nervous system depressants such as alcohol and opiates, the potential for toxicity and fatal overdose increases.

However, in more recent years, since the end of the Bretton Woods system in 1971, with the increasing influence of Monetarist schools of thought in the 1980s, and particularly in the face of large sustained trade imbalances, these concerns — and particularly concerns about the destabilising effects of large trade surpluses — have largely disappeared from mainstream economics discourse and Keynes ' insights have slipped from view.

However, since piston-engined aircraft rely upon magnetos to provide spark to their cylinders rather than a battery powered ignition coil system, this theory is not strongly convincing.

However, today the IUPAC system of chemical nomenclature allows chemists to specify by name specific compounds amongst the vast variety of possible chemicals.

However, both of the first two markets pay into and receive benefits from the financial market, which handles and regulates the actual money in the economic system.
