A method and system for presence state assignment based on schedule information in an instant messenger system. In one embodiment, the method may include storing schedule information corresponding to a given user, where the schedule information is indicative of an activity status of the given user at a given time. The method may further include querying the schedule information, and if a current presence state of an instant messenger does not correspond to the activity status indicated by the schedule information, assigning a different presence state that corresponds to the activity status in response to the querying, where the current presence state and the different presence state each correspond to the given user.

Nonwoven webs having substantially aligned fibers can be formed in an apparatus having a direction of motion corresponding to the direction of web formation. The web is formed in the presence of at least one secondary fluid stream that oscillates the filaments or resulting attenuated fibers to and fro generally in and against the direction of motion so that a majority of the collected fibers are aligned within ±20° of the direction of motion and fibers having lengths of about 1-10 cm can be teased from the web. The resulting nonwoven webs are especially useful for forming pleated filtration media having pleats generally transverse to the direction of motion.
摘要:
Interactions between molecules which are components of self-assembled monolayers and other molecules can be amplified and transduced into an optical signal through the use of a mesogenic layer. The invention provides a device and methods for detecting analytes. The device comprises a substrate onto which a self-assembled monolayer is attached and a mesogenic layer which is anchored by the self-assembled monolayer. The mesogenic layer undergoes a change in conformation in response to the molecular interaction.
