Abstract: A file marker device adapted for use with a folder. The folder to which the device can be affixed comprises a front flap having a first top edge, a rear flap connected to the front flap by a folder bottom, the rear flap having a second top edge. Hanging folders often also comprise a plurality of equally spaced parallel slots near at least a first or second top edge. The file marker device can comprise a support portion having two opposed end tabs, each of the end tabs being capable of engaging one of the plurality of equally spaced parallel slots; and an indicator arm moveably attached to the support portion, the indicator arm being moveable about a pivot point from a first position to a second position. In some embodiments the file marker device also comprises a shield portion and/or a portion adapted for exhibiting identifying indicia.

Abstract: It is common in distributed systems to replicate data. In many cases, this data evolves in a consistent fashion, and this evolution can be modeled. A probabilistic model of the evolution allows us to estimate the divergence of the replicas and can be used by the application to alter its behavior, for example, to control synchronization times, to determine the propagation of writes, and to convey to the user information about how much the data may have evolved. In this paper, we describe how the evolution of the data may be modeled and outline how the probabilistic model may be utilized in various applications, concentrating on a news database example.
