Abstract: A gateway is configured to communicate with a satellite so as to control the preceding/pre-equalization of a communication between the satellite and at least one terminal based on a channel state of a channel between the terminal and the satellite. The gateway is configured for receiving a location-related information indicating a location of the terminal and for determining a predicted channel state information related to the channel state between the terminal and the satellite using the location-related information. The gateway is configured for controlling the signal processing so as to precode the communication according to the predicted channel state information.

Abstract: A method for measuring interactions between labeled particles and ligands comprising the steps: a) providing a sample comprising labeled particles and ligands in a solution, wherein the labeled particles are dissolved or dispersed in the solution or are immobilized on a solid support; b) exciting fluorescently the labeled particles and detecting the fluorescence of the excited particles at a predetermined temperature; c) repeating steps (a) and (b) multiple times at different concentrations of the ligands in the solution; and d) determining the interaction between the labeled particles and the ligands based on the ligand concentration dependent change of the fluorescence of the labeled particles, wherein the labeled particles are labeled with one or more dyes.

Abstract: A self-propelled harvester is disclosed. The harvester comprises a drive motor, an attachment drive that has a hydraulic pump configured to drive a hydraulic motor to drive an attachment positioned on a feed device of the harvester, and a control device. The control device controls the attachment drive by accessing an attachment-specific parameter set tailored to the attachment that is connected to the harvester so that the hydraulic motor generates an attachment-specific operating torque which is lower than a maximum torque specific to the attachment to be driven. Further, the control device is configured, when a load peak is detected, to control the hydraulic motor to increase the operating torque generated by the hydraulic motor up to the attachment-specific maximum torque by changing a preset pivot angle.
