Abstract: In a general aspect, an apparatus can include a substrate and a post disposed on the substrate. The post can include a plurality of nanotubes and extend substantially vertically from the substrate. The post can have an aspect ratio of a height of the post to a diameter of the post of greater than or equal to 25:1.

Abstract: An acknowledgment frame delay duration setting method, apparatus, and system related to the field of wireless communications technologies, and where the method includes obtaining first acknowledgment frame delay duration corresponding to a first mobile station (STA), and sending, to the first STA, a first indication frame carrying the first acknowledgment frame delay duration such that the first STA feeds back an acknowledgment frame after a delay of the first acknowledgment frame delay duration when receiving a data frame.

Abstract: A data transmission method and a device are provided. A receive end receives, using a first protocol, K packets sent by a transmit end, determines a second sending delay based on a target packet when detecting that the target packet is lost; sends an ACK message to the transmit end by using the first protocol based on the second sending delay, where the ACK message is used to notify the transmit end that the receive end has received all packets sent by the transmit end; sends a retransmission request for the target packet to the transmit end by using a second protocol, and receives, by using the second protocol, the target packet retransmitted by the transmit end. The method ensures high and stable throughputs, and lowers a memory requirement compared with an improved technology that uses TCP streams to transmit data, thereby saving system resources.

Abstract: The present approach relates to the fabrication and use of a probe array having multiple individual probes. In one embodiment, the probes of the probe array may be functionalized such that certain of the probes are suitable for electrical sensing (e.g., recording) or stimulation, non-electrical sensing or stimulation (e.g., chemical sensing and/or release of biomolecules when activated), or a combination of electrical and non-electrical sensing or stimulation.

Abstract: A method and a device for creating a pattern matching state machine are provided. The method includes: obtaining a predefined keyword set; generating a Goto function according to the keyword set; constructing a Failure function according to the generated Goto function, and setting that an acceptable input set of the Failure state of each state is not a subset of an acceptable input set of the state, where the acceptable input set of the state indicates that when any symbol within the symbol set is input in the state, the Goto function of the state does not fail; and generating an Output function according to the Goto function and the Failure function.

Abstract: Surface field electron emitters using a carbon nanotube yarn and a method of fabricating the same are disclosed. To fabricate the carbon nanotube yarn for use in fabrication of simple and efficient carbon nanotube field electron emitters, the method performs densification of the carbon nanotube yarn during rotation of a plying unit and heat treatment of the carbon nanotube yarn that has passed through the plying unit without using organic or inorganic binders or polymer pastes. The method fabricates the carbon nanotube yarn with excellent homogeneity and reproducibility through a simple process. The carbon nanotube yarn-based surface field electron emitters can be applied to various light emitting devices.
