A buoy-type high-frequency ground wave radar system. A buoy platform is used as an offshore carrier of a ground wave radar. A sky wave emission subsystem is disposed on a shore base and emits a high-frequency electromagnet wave. After the high-frequency electromagnet wave is refracted by an ionized layer and is reflected by a sea surface, a sky wave signal is formed. An attitude measurement subsystem measures and acquires attitude data of the buoy platform in real time. A ground wave radar subsystem receives a ground wave signal by using the ground wave radar, and processes the signal to form a ground wave doppler spectrum. Simultaneously, the sky wave signal is received, ionized layer disturbance compensation is performed on the sky wave signal in a frequency domain and then the sky wave signal is processed to form a sky wave doppler spectrum. The ground wave radar subsystem reconstructs an actual geographic coordinate system according to the attitude data measured by the attitude measurement subsystem and then the ground wave or the sky wave doppler spectrum is used to inverse wind wave flow data in the reconstructed actual geographic coordinate system. The sky wave emission subsystem and the ground wave radar subsystem carry out time synchronization by means of a GPS synchronization networking mode. The system can detect a sea region having any distance and is applicable to high sea detection.

According to one aspect, a method of switching a first gateway from a voice mode to a facsimile mode comprises: configuring the first gateway to the voice mode for communication with a second gateway over a packet network, receiving a plurality of data packets from the second gateway over the packet network, analyzing one or more of the plurality of data packets, such as UDP packets, and configuring the first gateway to the facsimile mode if the analyzing determines that the one or more of the plurality of data packets carry facsimile data packets. The analyzing may include calculating a length of the UDP payload in accordance with UDPTL packet structure, and deciding the UDP payload includes a UDPTL packet if the calculated length is equal to UDP payload length, as indicated in the UDP header.

Overexpressing osa - miR156e in rice produced a bushy mutant and osa - miR156e regulation of tillering may do this through the strigolactones (SLs) pathway. Appropriate downregulation of osa - miR156 expression contributed to the improvement of plant architecture. Tillering is one of the main determinants for rice architecture and yield. In this study, a bushy mutant of rice was identified with increased tiller number, reduced plant height, prolonged heading date, low seed setting, and small panicle size due to a T-DNA insertion which essentially elevated the expression of osa-miR156e. Transgenic plants with constitutive expression of osa-miR156e also had the bushy phenotype, which showed osa-miR156 may control apical dominance and tiller outgrowth via regulating the strigolactones signaling pathway. Furthermore, the extent of impaired morphology was correlated with the expression level of osa-miR156e. In an attempt to genetically improve rice architecture, ectopic expression of osa-miR156e under the GAL4-UAS system or OsTB1 promoter was conducted. According to agronomic trait analysis, pTB1:osa-miR156e transgenic plants significantly improved the grain yield per plant compared to plants overexpressing osa-miR156e, even though the yield was still inferior to the wild type, making it a very interesting albeit negative result. Our results suggested that osa-miR156 could serve as a potential tool for modifying rice plant architecture through genetic manipulation of the osa-miR156 expression level.

Various methods and systems for establishing modem relay connections are provided. For example, a modem relay method for use by a first gateway device in communication with a calling modem comprises the exemplary steps of: receiving a call from the calling modem for establishing a communication with a remote modem; requesting a second gateway device to place a call to the remote modem for establishing the communication; transmitting ANSam to the calling modem for a predetermined period of time according to an ANSam message received from the second gateway device in an RFC2833 message via a packet network; monitoring for detection of a CM signal from the calling modem; monitoring for detection of an AA signal from the calling modem; monitoring for receipt of a modulation type message from the second gateway device; and monitoring for receipt of a pass through mode message from the second gateway device.

An aircraft tracing method and system. The method comprises: gathering geographical location information of an aircraft and image data of an aircraft flight area (S11); establishing a corresponding relationship between the geographical location information and the image data which are gathered at a same moment (S12); transmitting the data having the established corresponding relationship; receiving the geographical location information and the image data having the established corresponding relationship at a receiving end (S21); drawing a flight path of the aircraft utilizing the geographical location information (S22); obtaining the geographical location information corresponding to a selected position in the flight path and displaying the image data corresponding to the geographical location information (S23). In this manner, the geographical location information corresponding to each frame image is added to video information by establishing the corresponding relationship between the geographical location information and the image data, thereby the geographical location corresponding to each frame video image can be conveniently obtained subsequently, providing a basis for tracing a route of the aircraft and monitoring the flight condition of the aircraft.
