Abstract: A process for selective removal of hydroxyl groups from phenolic compounds is disclosed. The process uses a combination of catalytic hydrodeoxygenation and catalytic direct deoxygenation to convert alkylphenols into alkylbenzenes.

Abstract: The present invention relates to a method for adapting a link using a polar-modulation (PQAM) constellation. It applies in particular to the communications in the sub-THz band, in which the oscillator of the receiver has phase fluctuations. In a PQAM-modulation constellation, the modulation symbols are distributed on concentric circles equidistant in the complex plane, each circle including the same number of symbols, the angular distribution of the symbols on a circle being uniform and identical regardless of the circle. The adaptation of the link is carried out by taking into account the thermal noise as well as the phase noise.

Abstract: A system including a coupler to couple a signal to a plurality of conductors of an electric network and a transmitter to select a plurality of modes to inject the signal into the plurality of conductors and to transmit the signal via the plurality of conductors. The plurality of modes is selected from a group consisting of a first mode, a second mode, and a third mode. The first mode includes injection of the signal through a selective combination of the plurality of conductors and circulation of current through ground. The second mode includes injection of the signal through a first conductor and return through a second conductor. The third mode includes injection of the signal through one or more first conductors and return through one or more second conductors. The first conductors are different than the second conductors.

Abstract: Method for increasing the performance of a communications system on a medium formed by multiple conductors which increases the performance of a communications system by means of the creation of numerous communication channels with a high degree of isolation between each other on the same physical medium formed by multiple conductors. The method can be extended to be used in various applications, such as the reuse of frequencies on the same channel, the increase of the capacity of the point-to-point links in a network and the improvement of performance and reliability when used with digital processing of signals for transmission or reception, among others.

Abstract: A system for transmitting and receiving data includes a physical adaptation block configured to separate the data into a plurality of frequency bands. Each of the frequency bands has an associated symbol time, and each of the associated symbol times is a whole multiple of one half of a smallest symbol time of all of the frequency bands. An analog front end is configured to provide the data in the plurality of frequency bands to a transmission medium.
