Abstract:
Provided are a transmitting apparatus, a transmitting method, a receiving apparatus, a receiving method and a channel status information updating method of a sensor node based on multiple channels. The transmitting apparatus and method transmit a wake-up signal for switching neighbor nodes in a power-saving mode in a transmission range of the sensor node to a wake-up mode in which the neighbor nodes wait to receive a message from the sensor node through the control channel, transmit a preamble message including a list of unused available channels from among the data channels to a receiving node to which data is transmitted from among the neighbor nodes through the control channel, receive an acknowledgement message including information that indicates a channel selected from the available channels from the receiving node through the control channel, transmit a connection confirmation message for switching neighbor nodes other than the receiving node to the power-saving mode through the control channel, and transmit data to the receiving node through the selected channel.
Abstract:
The present invention relates to a method for phosphorylation site-specific labeling of phosphoproteome with a site-specific tagging reagent and analyzing of the resulting labeled one, more especially, a method for in-situ tagging of phosphorylation sites of phosphoproteins retained in polymeric gel with a nucleophilic tagging reagent. It also relates a method for generating new proteolytic cleavable sites at formerly phosphorylation sites by a proper choice of a nucleophilic tagging reagent. It also relates to a method for phosphopeptides analysis and phosphorylation site identification by in-gel digestion of the previously in-gel tagged proteins and subsequent mass analysis of the resulting peptides. The invention provides in-gel chemical tagging method for phosphoaminoacid residue of phosphoproteins retained in polymeric gel matrix. Phosphoprotein can be immobilized into gel matrix by a variety of methods such as gel electrophoresis. The immobilized phosphoproteins are retained in gel matrix during tagging reaction to phosphorylated aminoacid residue of phosphoproteins, and the resulting tagged proteins are also retained in gel matrix till following purification steps like washing of the tagging reagents are accomplished. The tagged proteins is digested by protease, and the resulting digested peptides is released from gel into solution and applied for peptide mass analysis.

Abstract:
Disclosed is an imaging apparatus for IR four-wave mixing polarization microscopy. The apparatus can include pump and probe beam sources, a polarizer, a beam combiner, a scanner, an optical focusing system, a collecting optical system, a dichroic beam splitter, a polarizing beam splitter, a photodetector, a polarization differential detector, and a data analyzer. The technology can be used to obtain a molecular vibrational microscopic image using a polarization-dependent nonlinear spectroscopic signal obtained through the focusing and spatial scanning of multi-wavelength laser beams in a sample.
Abstract:
Provided is an apparatus and method for controlling multi-channel access in USN-based MAC. The multi-channel access control apparatus includes a channel scanner, a control channel preoccupier, and an available channel exchanger. The channel scanner scans at least one or more available channels among the N data channels in a Tx sensor node. The control channel preoccupier preoccupies, in the Tx sensor node, the control channel through control channel sensing and back-off and broadcasts a preamble on the control channel periodically. The available channel exchanger detects, in an Rx sensor node, the available channels available to the Tx sensor node on the basis of the received preamble, selects a channel available to the Rx sensor node among the detected available channels, and transmits information about the selected channel to the Tx sensor node.
