Since complex scalar fields admit two different kinds of annihilation operators, which are related by conjugation, such fields describe charged bosons.

Since 31 December 2003, the system has been closed to new users, at that time, it covered 100 % of the Spanish population, but now some antennas have been given to GSM operators.

Since virtually every calculation in quantum mechanics involves vectors and linear operators, it can involve, and often does involve, bra-ket notation.

Since the live operators are cutting from one live feed to another, the physical action of the shots matches very closely.

Since the liberalization of the telecommunications market, OTE has been slowly losing market share to " alternative ", competing telecom operators, such as Vivodi, Q-Telecom, Tellas and Forthnet.

Since the early 1940s, Kingman Reef has had very little human contact, though amateur radio operators from around the world have occasionally visited the reef to put it " on the air " in what is known as a DX-pedition.

Since the simple arithmetic operators are all binary ( at least, in arithmetic contexts ), any prefix representation thereof is unambiguous, and bracketing the prefix expression is unnecessary.

Since 1878, telephone communications were handled by telephone switchboards, staffed by telephone operators.

Since SSTV systems operate on voice frequencies, amateurs use it on shortwave ( also known as HF by amateur radio operators ), VHF and UHF radio.

Since it was used by individual operators, vehicles would vary greatly in wheel spacing ( gauge ) and the plate rail coped better.

Since the deregulation of the postal sector, different postal operators can install mail collection boxes in New Zealand's streets.

Since most of the line is single track, the extra trains display a green disk with a diagonal white line on the front to indicate to station staff and signal operators that there is a train following in the same direction

Since May 2011, the WinMX network has been under protocol level attack from a disgruntled developer who disagrees with those operating the network support infrastructure ( user support forums & peer cache operators ).

Since the early 1920s amateur radio operators, limited to lower transmitter power than commercial radio, have taken advantage of skywave for long distance or DX communication.

Since operators corresponding to different modes operate in different sub-spaces of the Hilbert space, the entire field is a direct product of over all the modes:

The binary temporal operators Since and Until were introduced by Hans Kamp in his 1968 Ph.

Since the operators are spacelike separated, a different order can only create states that differ by a phase.

Since and are second quantization operators defined in every point in space they are called quantum field operators.

Since the effects on the users of a server under a UDP can be significant, if the users want to post, the impact of a UDP can induce the operators of an offending server to address problems quickly.

Since its completion, Harvie Passage has been a popular attraction for watercraft operators along the Bow while still supplying water to its irrigation district.

Since draglines are typically large, complicated and very expensive, training new operators can be a tricky process.

Since most satellite phones are built under license or the manufacturing of handsets is contracted out to OEMs, operators have a large influence over the selling price.

Since the introduction of full mobile number portability in Ireland, access codes have become less relevant as mobile telephone users may now retain their mobile telephone numbers when moving between mobile network operators.

Since Claudius ( like most of the members of his dynasty ) heavily criticized his predecessors and relatives in surviving speeches, it is not hard to imagine the nature of Suetonius ' charge.

Since current can be the flow of either positive or negative charges, or both, a convention for the direction of current which is independent of the type of charge carriers is needed.

Since the electrons have a negative charge, they are repelled by the cathode and attracted to the anode.

Since the direction of an electric field is defined as the direction of the force on a positive charge, electric field lines point away from a positive charge and toward a negative charge.

Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero.

Since charge is preserved, some vertices still have positive charge.

Since 2008 the Afghan National Security Forces ( ANSF ) are in charge of security in the city.

Since taking over the franchise, Attanasio has worked hard to build bridges with Milwaukee baseball fans, including giving away every seat to the final home game of 2005 free of charge and bringing back the classic " ball and glove " logo of the club's glory days on " Retro Friday " home games, during which they also wear versions of the team's old pinstriped uniforms.

Since the theory of electric charge is dubbed " electrodynamics ", the Greek word " chroma " Χρώμα ( meaning color ) is applied to the theory of color charge, " chromodynamics ".

Since that time, the entity in charge of telecommunication had undergone a number of organizational restructuring changes.

* Since the water molecule is not linear and the oxygen atom has a higher electronegativity than hydrogen atoms, it carries a slight negative charge, whereas the hydrogen atoms are slightly positive.

Since the vacuum offered no medium for an electric fluid to travel, this discovery could only be explained via a particle carrying a negative charge and moving through the vacuum.

Since electromagnetism was known to be a wave generated by a changing electric or magnetic field ( a continuous, wave-like entity itself ) an atomic / particle description of electricity and charge was a non sequitur.

Since the charge gradually leaked away, it was necessary to scan the tube periodically and rewrite every dot ( similar to the memory refresh cycles of DRAM in modern systems ).

Since the force imparted by a magnetic field is proportional to the charge on the particle, and the acceleration is proportional to the force divided by the mass of the particle, the magnets required to contain uranium gas would be impractically large ; most such designs have focussed on fuel cycles that do not depend upon retaining the fuel in the reactor.

Since the current available depends on the state of charge of the dry cell, a multimeter usually has an adjustment for the ohms scale to zero it.

Since this force varies with the position of the charge and by Coloumb's Law it is defined at all points in space, is a continuous function of the charge's position ( x, y, z ).

Since shot noise is a Poisson process due to the finite charge of an electron, one can compute the root mean square current fluctuations as being of a magnitude

Since then, the " Three Eastern Provinces " ( 東三省 ) was officially used by the Qing government in China to refer to this region, and the post of Viceroy of Three Northeast Provinces ( 東三省總督 ) was established to take charge of these provinces.

Since 2000, some major OCR vendors began offering WebOCR & Online software, a number of new entrants companies seized the opportunity to develop innovative Web-based OCR services, some of which are free of charge.

Since Schiele was in charge of the food stores in the camp, he and Edith could enjoy food beyond rations.
