For an analysis method, a first specimen and a second specimen are prepared, in which different phthalate esters, for example DEHP and DINP, adhere in different states to a pair of predetermined base films, such as PVC, on metal plates. A metal reflection IR spectrum (P) and a metal reflection IR spectrum (Q) are acquired by radiating electromagnetic waves on the prepared first specimen and the second specimen respectively. Significantly different spectra are obtained for different phthalate esters, and the types of phthalate esters are identified by using such spectra.


Embodiments of this disclosure provide a beam-based information transmission method and apparatus and a communications system. The information transmission method includes: a base station receives a measurement result obtained by measuring one or more beams and transmitted by user equipment; selects one or more transmission beams for the user equipment based on the measurement result; transmits information on the selected transmission beams to the user equipment; and performs diversity transmission of information by using the selected transmission beams. With the embodiments of this disclosure, a problem of coverage of the system may further be solved, and a good tradeoff between a diversity gain and a beamforming gain may be obtained. Furthermore, inter-cell interference may be efficiently suppressed, and an average throughput of the cell may be improved.


A wireless communication system includes a baseband processing device configured to transmit a data signal via an optical transmission line, and a wireless device configured to receive the data signal via the optical transmission line and carry out wireless transmission of an output signal obtained by amplifying the data signal, wherein the wireless device is configured to amplify the data signal to generate the output signal, generate a feedback signal according to the output signal, and transmit the feedback signal to the baseband processing device via the optical transmission line, and wherein the baseband processing device is configured to acquire the feedback signal from the wireless device, and execute first processing of multiplying the data signal by a distortion compensation coefficient corresponding to an inverse characteristic of distortion in the radio frequency circuit based on the feedback signal.


A first node included in a first layer determines whether there has occurred a failure in a sink node included in a second layer subordinate to the first layer. The first node requests a second node included in the second layer to collect information of a third node included in a third layer subordinate to the second layer when the first node determines that there has occurred a failure in the sink node. The first node determines a fourth node serving as a substitute for the failed sink node included in the second layer on a basis of the information of the third node collected by the second node.

A radio communication system for exchange of information used in a radio frame format between a base station and a terminal, the radio communication system wherein, the base station includes: a selector configured to select a radio frame format for each terminal from a plurality of radio frame formats divided in a frequency direction; a frame format generator configured to map a radio channel, includes a dedicated control channel and data channel, for each terminal in the selected radio frame format, a controller configured to control the dedicated control channel position in a time direction in the radio frame format for the terminal to differ from other dedicated control channel position for other terminal; a transmitter configured to transmit information indicating the position of the dedicated control channel to the terminal that includes: a receiver configured to receive the information indicating the position of the dedicated control and radio channel.


A semiconductor structure includes first, second, and third transistor elements each having a first screening region concurrently formed therein. A second screening region is formed in the second and third transistor elements such that there is at least one characteristic of the screening region in the second transistor element that is different than the second screening region in the third transistor element. Different characteristics include doping concentration and depth of implant. In addition, a different characteristic may be achieved by concurrently implanting the second screening region in the second and third transistor element followed by implanting an additional dopant into the second screening region of the third transistor element


A control contact pin 23 is connected to a GND 110 when an electronic apparatus is connected to an AC adapter 1. The control contact pin 23, when connected to the GND 110, receives an input of a control signal output by the electronic apparatus. A detection unit 109 detects whether the control contact pin 23 is connected to the GND 110 and whether the control contact pin 23 receives the input of the control signal. When the detection unit 109 detects that the control contact pin 23 is not connected to the GND 110 or the control contact pin 23 is connected to the GND 110 and receives the input of the control signal, a control unit 108 stops an operation of a switching unit 106. When the detection unit 109 detects that the control contact pin 23 is connected to the GND 110 and yet does not receive the input of the control signal, the control unit 108 operates the switching unit 106.

A relation validation system comprising: a relation extraction module configured to extract a given relation r between entities from a particular one of n data sources s_(1).....s_(n); and a relation validation module connected to the relation extraction module and to a knowledge base storing relations, validity scores for the relations and reliability scores for the n data sources, the relation validation module being configured: if the given relation is not already represented in the knowledge base: to set a default validity score Pr(r) and store the given relation and the default validity score in the knowledge base; and if the given relation is already represented by one or more associated relations in the knowledge base: to use one or more validity scores for the one or more associated relations from the knowledge base to set a prior validity score Pr(r), to retrieve a prior reliability score Pr(s) for each data source from which the given relation or an associated relation has been extracted, to compute a posterior validity score V_(j) for the given relation from the prior reliability scores Pr(s), and to compute a posterior reliability score R for each data source from which the given relation or an associated relation has been extracted from the prior validity score V_(j).


When an electronic mail is transmitted, a computer outputs (S25) to a display device (111) a transmission confirmation screen (21) on which a destination or an attached file name is displayed, the destination or the attached file name being different from a destination or an attached file name that has been set by a user in the electronic mail, and on which whether transmission of the electronic mail will be performed is selectable. Upon receipt of selection of whether the transmission will be performed, the computer outputs (S27, S31, S33) to the display device message information (31, 35, 51) that varies according to a result of the selection of whether the transmission will be performed on the transmission confirmation screen.
