Abstract: A generative system for producing one or more conformers of a selected molecule includes a processor, and a memory coupled to the processor, wherein machine-readable instructions are stored in the memory, and wherein the machine-readable instructions, when executed on the processor, configure the processor to receive by a generative model both a training dataset and an input dataset, and generate by the generative model one or more synthetic conformers of the selected molecule using the input dataset associated with the selected molecule.

Abstract: An arrangement and methods for operating and for determining the speed of an electrical machine connected to a power electronic switching device and for supplying energy to a control device of the power electronic switching device. The arrangement and methods have an inductive decoupling device arranged on an electrical conductor leading from the switching device to the electrical machine, wherein a frequency determination device is used to determine the frequency of a voltage associated with a current in the electrical conductor and thus indirectly the speed of the electrical machine, and wherein a rectified output voltage of the decoupling device forms a voltage source for the control device.

Abstract: A power semiconductor arrangement has a switching facility, a housing, having a load connection facility for connecting in an electrically conductive manner to an external supply line and having a first plug-in connecting facility for plug-in connecting to an external second plug-in connecting facility. The housing has a first opening through which a connecting facility for connecting the load connection facility and the associated external supply line is accessible. A cover facility for covering the first opening is on the housing so as to be mechanically movable from a first end position into a second end position and has a first locking facility which cooperates with the external second plug-in connecting facility, whereby the first opening is closed with the cover facility as long as it is in its first end position, as long as the external second plug-in connecting facility is inserted into the first plug-in connecting facility.

Abstract: A power semiconductor device comprising a first housing having a cutout with an opening, and a second housing. The device has a load element having external and internal sections, and a feedthrough section pressing through the opening. The feedthrough section has a first outer edge region which tapers laterally towards a first outer edge thereof and a second outer edge region which tapers laterally towards a second outer edge thereof. The first and second outer edge regions face away from one another. The first outer edge is near the lateral first end of the opening and the second outer edge is near the lateral second end of the opening. A first seal is positioned between the first housing and the feedthrough section and a second seal is positioned between the second housing and the feedthrough section. The seals contact one another laterally from the first and second outer edges.
