( In order not to interpret +++ which may be a part of data as the escape sequence the sender stops communication for one second before and after the +++). When the modem encounters this in a stream of data, it switches from its normal mode of operation which simply sends any characters to the phone, to a command mode in which the following data is assumed to be a part of the command language.

When a moth encounters a much closer artificial light and uses it for navigation, the angle changes noticeably after only a short distance, in addition to being often below the horizon.

When a caesium atom within the chamber encounters a photon from the lamp, it is excited to a higher energy state, emits a photon and falls to an indeterminate lower energy state.

When Buffy encounters Oz, he is the leader of a pack of werewolves who can completely control their wolf forms ; Oz assists in the final battle of the book, set during a full moon.

* When one encounters another repeatedly in various locations such that it seems to be more than coincidence, one can refer to yuánfèn.

When he goes upstairs, after noticing some firelight there, he encounters the woman, who is stealing hair from the dead bodies on the second floor.

When the party encounters monsters the view switches perspective and players are presented with several options on a menu ; these first-person menu-based battles have become a staple of the series.

When a T < sub > h </ sub > cell encounters and recognises the antigen, on an APC, the TCR-CD3 complex binds strongly to the peptide-MHC complex present on the surface of professional APCs.

When the reader finally encounters the unknown woman, it transpires that the couple are being paid to have sex in front of upper-class clientele.

When Red Dwarf encounters a Holoship, with an all-hologram crew composed of the " best and brightest ", Rimmer desperately wants to join.

When the person again encounters the allergen, these basophils and mast cells that have bound to IgE release histamine, prostaglandins and leukotrienes, which causes inflammation of the surrounding tissues, resulting in allergic symptoms.

When this thread encounters a high latency event ( L2 cache miss, etc.

When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism.

When the atoms are relatively similar in size, the atom exchange method usually happens, where some of the atoms composing the metallic crystals are substituted with atoms of the other constituent.

When more electrons are added to a single atom, the additional electrons tend to more evenly fill in a volume of space around the nucleus so that the resulting collection ( sometimes termed the atom ’ s “ electron cloud ” ) tends toward a generally spherical zone of probability describing where the atom ’ s electrons will be found.

When two monosaccharides undergo dehydration synthesis, water is produced, as two hydrogen atoms and one oxygen atom are lost from the two monosaccharides ' hydroxyl group.

When an electron in an excited molecule or atom descends to a lower energy level, it emits a photon of light equal to the energy difference.

When oxygen binds to the iron complex, it causes the iron atom to move back toward the center of the plane of the porphyrin ring ( see moving diagram ).

When ionized hydrogen is written as " H < sup >+</ sup >" as in the solvation of classical acids such as hydrochloric acid, the hydronium ion, H < sub > 3 </ sub > O < sup >+</ sup >, is meant, not a literal ionized single hydrogen atom.

When a silver-109 atom, which comprises approximately half of all silver in existence, catches a neutron, it undergoes a beta decay to become cadmium-110.

When implanted in a semiconductor, each dopant atom can create a charge carrier in the semiconductor after annealing.

When the energy difference between the atomic orbitals of two atoms is quite large, one atom's orbitals contribute almost entirely to the bonding orbitals, and the others atom ’ s orbitals contribute almost entirely to the antibonding orbitals.

* When an < sup > 235 </ sup > U atom captures a neutron, it is converted to an excited state of < sup > 236 </ sup > U. About 81 % of the excited < sup > 236 </ sup > U nuclei undergo fission, but the remainder decay to the ground state of < sup > 236 </ sup > U by emitting gamma radiation.

When an atom undergoes nuclear fission, a few neutrons ( the exact number depends on several factors ) are ejected from the reaction.

When a heavy atom undergoes nuclear fission it breaks into two or more fission fragments.

When an X-ray photon collides with an atom, the atom may absorb the energy of the photon and boost an electron to a higher orbital level or if the photon is very energetic, it may knock an electron from the atom altogether, causing the atom to ionize.

When such cascades recoil and reach the target surface with an energy above the surface binding energy, an atom can be ejected.

When an atom is probed by an external mechanism, such as a photon or a beam of electrons with energies in the range of 2 keV to 50 keV, a core state electron can be removed leaving behind a hole.

When an antihydrogen atom comes into contact with ordinary matter, its constituents quickly annihilate.
