Unlike beta decay, alpha decay is governed by the interplay between the nuclear force and the electromagnetic force.

Unlike leptons, hadrons can interact via the strong force, so the energy levels of hadronic atoms are influenced by nuclear forces between the nucleus and the hadron.

Unlike classical phenomena such as the nuclear, electromagnetic, and gravitational fields, entanglement is invariant under distance of separation and is not subject to relativistic limitations such as speed of light.

During the speech, Edwards ostensibly emphasized a potential property of positron weaponry, a type of antimatter weaponry: Unlike thermonuclear weaponry, positron weaponry would leave behind " no nuclear residue ", such as the nuclear fallout generated by the nuclear fission reactions which power nuclear weapons.

Unlike true stars, brown dwarfs have too little mass to sustain nuclear fusion so they do not belong to this category either.

Unlike reactors that use relatively slow low energy ( thermal ) neutrons, fast neutron reactors need nuclear reactor coolant that does not moderate or block neutrons ( like water does in an LWR ) so that they have sufficient energy to fission actinide isotopes that are fissionable but not fissile.

Unlike most multi-unit nuclear power plants, each unit at Palo Verde is an independent power plant, sharing only a few minor systems.

Unlike most nuclear power sources, which use nuclear radiation to generate heat, which then generates electricity ( thermoelectric and thermionic sources ), betavoltaics use a non-thermal conversion process, using a semiconductor p-n junction.

Unlike the AEC work, which was intended to study the reactor design itself, NERVA's goal was to produce a real engine that could be deployed on space missions.

Unlike commercial reactors, which are surrounded by concrete, the Pluto reactor had to be small and compact enough to fly, but durable enough to survive a trip to a potential target.

Unlike Peach Bottom, Dragon, AVR, HTTR, and HTR-10, all of which represent successful tests proving the principle of the HTGR technology, Fort St. Vrain was arguably doomed by the engineering mistake to use a first of a kind engineered, high-complexity steam turbine helium circulator with multiple fluid bearings instead of a simple, commercial off the shelf, KISS principle, low-complexity electric motor-based helium circulator, such as the electrical coolant circulators successfully used for decades in the UK's AGCR, which have stood and do stand the test of time in a similar, yet far more chemically hostile environment than that of a helium-cooled reactor core.

Unlike Wilson, who at times seemed almost anti-intellectual in his earthy pragmatism.

Unlike the simple counting board used in elementary schools, very efficient suanpan techniques have been developed to do multiplication, division, addition, subtraction, square root and cube root operations at high speed.

Unlike the Semitic Akkadians and their descendant Assyrians, whose Anatolian possessions were peripheral to their core lands in Mesopotamia, the Hittites were centred at Hattusa in north-central Anatolia by 2000 BC.

Unlike many child actors, Mumy entered the profession at his own insistence, and his parents took pains to make sure he matured properly in his job.

Unlike Inter-city, it stops at most or all stations between cities.

Unlike the American game, Canadian rules allow a drop kick to be attempted at any time by any player, but the move is very rare.

Unlike the trumpet, which has a cylindrical bore up until the bell section, the tubing of the cornet has a mostly conical bore, starting very narrow at the mouthpiece and gradually widening towards the bell.

Unlike honors programs at individual CUNY colleges, Macaulay Honors College students must be accepted into and begin the program as freshmen.

Unlike modern systems, which can be applied to widely different databases and needs, the vast majority of older systems were tightly linked to the custom databases in order to gain speed at the expense of flexibility.

Unlike his brother Titus, Domitian was not educated at court.

Unlike most social canids ( but similar to African wild dogs ), dholes let their pups eat first at a kill.

Unlike physician-assisted suicide, withholding or withdrawing life-sustaining treatments with patient consent ( voluntary ) is almost unanimously considered, at least in the United States, to be legal.

Unlike the TEM, where electrons of the high voltage beam carry the image of the specimen, the electron beam of the scanning electron microscope ( SEM ) does not at any time carry a complete image of the specimen.

Unlike Common Lisp, Scheme existed at the time Stallman was rewriting Gosling Emacs into GNU Emacs, but he chose not to use it because of its comparatively poor performance on workstations, and he wanted to develop a dialect which he thought would be more easily optimized.

Unlike the other islands of the archipelago, Fuerteventura has a shelf which at some points goes up to 30 km, making it an ideal place to practice this sport.

Unlike pagan Rome, Christian Europe did not exercise a universal prohibition of the dissection and autopsy of the human body and such examinations were carried out regularly from at least the 13th century.

Unlike geocaching, nothing is to be left at the dashpoints ; the sole objective is to visit them within the time limit.

Unlike any Greeks, the Etruscans instead pictured a full-grown bearded Heracles at Hera's breast: this may refer to his adoption by her when he became an Immortal.

Unlike any other element, helium will remain liquid down to absolute zero at normal pressures.

Unlike prior versions, Windows for Workgroups 3. 11 ran in 386 enhanced mode only, and needs at least an 80386SX processor.

Unlike most battles of the Second Punic War, at Zama, the Romans were superior in cavalry and the Carthaginians had the edge in infantry.

Unlike many children, Simon was exposed to the idea that human behavior could be studied scientifically at a relatively young age due to the influence of his mother ’ s younger brother, Harold Merkel, who had studied economics at the University of Wisconsin – Madison under John R. Commons.

Unlike woven fabrics, where strands usually run straight horizontally and vertically, yarn that has been knitted follows a loopy path along its row, as with the red strand in the diagram at left, in which the loops of one row have all been pulled through the loops of the row below it.
