    • at A preposition of extremely various use, primarily meaning to, without implication, in itself, of motion. It expresses position attained by motion to, and hence contact, contiguity, or coincidence, actual or approximate, in space or time. Being less restricted as to relative position than other prepositions, it may in different constructions assume their office, and so become equivalent, according to the context, to in, on, near, by, about, under, over, through, from, to, toward, etc.
    • at Of simple local position: With verbs of rest (be, live, etc.): In, on, near, by, etc., according to the context: denoting usually a place conceived of as a mere point: as, at the center, at the top, at the corner, at the end, at the next station, at the bend of the river, at the north pole, at No. 48 Main street, etc. So with names of towns, etc.: as, at Stratford, at Lexington, etc.; but if the city is of great size in is commonly used: as, in London, in Paris, in New York; unless, again, the city is conceived of as a mere geographical point: as, our financial interests center at New York. The place implied by at may be left indeterminate, with a reference rather to condition than to mere location: as, at school, at college, at court, at sea, etc. At may also express personal proximity: as, at one's side, at one's heels, at one's elbow, etc. At hand, near by, has lost its personal reference.
    • at With verbs of motion: Through, by (implying a starting-point or a point where a thing enters or departs): as, to enter at the window, to go out at the back door.

    • at Of circumstantial position, state, condition, manner, environment, etc., in a great variety of relations developed from the local sense: as, at dinner, at play, at work, at service, at right angles, at full length, at odds, at ease, at war, at peace, at will, at pleasure, at discretion, etc.
    • at Of relative position: implying a point in an actual or possible series, and hence used of degree, price, time, order, occasion, etc.: as, at the beginning, at the third house from the corner, at nine years of age, at seventy degrees in the shade, at four dollars a yard, at ten cents a pound, at half past six, at midnight, at first, at last, etc.
    • at [In all uses, especially in those last mentioned, at is very frequent in idiomatical phrases: as, at all, at most, at least, at last, at length, at any rate, at stake, at one, at once, at large, at present, etc., for which see the principal words, all, most, least, etc.]
    • at With the infinitive: To.
    • at [Now only dialectal, but common in Middle English, and the regular use in Scandinavian, to which the English use is due. A relic of this use remains in ado, originally at do. See ado.]
    • at An obsolete and dialectal form of that.
    • at A prefix of Anglo-Saxon origin, meaning at, close to, to: common in Middle English, but now obsolete. A relic of it remains in twit, originally at-wite. In atone, the at- is not properly a prefix, but is the preposition merged with its object.

Scaling Law and Aging Phenomena in the Random Energy Model
The graph G is said to be have zero boundary if P{l : l ∈ L} is a 1-cycle; i.e., for each vertex z p ∈ V , the number of edges beginning at z p equals the number ending at z p . (There must be at least one edge beginning at each vertex, since G is assumed to be connected.

Since z 1 and zn are connected by a chain of loops in G , we can choose disjoint sets of edges L′ , L′′ ⊂ L such that L′ forms a path starting at z 1 and ending at zn , and L′′ forms a path starting at zn and ending at z 1 .
