Discrete Mathematics for Green Route Planning

How can parcels and freight be delivered in a more resource-saving and sustainable way? Since 2017, the University of Bonn and the Deutsche Post DHL Group cooperate in the area of route planning. The Research Institute for Discrete Mathematics has developed an algorithm that exploits the considerable optimization potential and is already being used successfully in practice. Therefore, the Deutsche Post DHL has founded the subsidiary company Greenplan that aims at using the algorithm for a wide variety of applications. The cooperation will now be continued for an unlimited period.

First Argelander professorship filled at the University of Bonn

How can different actors make joint decisions when they have different information or face uncertainties? This and other questions are tackled by mathematician and theoretical economist Dr. Florian Brandl, who will take up an Argelander Professorship at the University of Bonn on April 1 and at the same time start as a Bonn Junior Fellow at the Hausdorff Center for Mathematics. He is the first researcher to hold such a professorship, as these are new positions created by the University of Bonn for outstanding up-and-coming professors who distinguish themselves by combining different disciplines. In Florian Brandl's research, these are mathematics, economics and computer science.

Paleontology: Microscope helps with dinosaur puzzle

Fossil sites sometimes resemble a living room table on which half a dozen different jigsaw puzzles have been dumped: It is often difficult to say which bone belongs to which animal. Together with colleagues from Switzerland, researchers from the University of Bonn have now presented a method that allows a more certain answer to this question. Their results are published in the journal Palaeontologia Electronica.

When memory qubits and photons get entangled

Encrypting data in a way that ensures secure communication is an ever-growing challenge because crucial components of today's encryption systems cannot withstand future quantum computers. Researchers around the world are therefore working on technologies for novel encryption methods that are also based on quantum effects. The phenomenon of so-called quantum entanglement plays a particularly important role here. This means that in a quantum network, the stationary qubits of the network are entangled with the communication channel, which usually consists of photons (light particles). For the first time, physicists at the University of Bonn have now been able to demonstrate quantum entanglement between a stationary qubit, i.e. a two-state quantum system, and a photon with direct coupling to an optical fiber. The study has been published in the journal "npj Quantum Information".

University Electoral Assembly confirms new Rectorate

The Electoral Assembly of the University of Bonn has elected four female and zwo male vice rectors who will take office in May 2021. The Assembly, consisting of members of the Senate and the University Council, convened online due to the pandemic. Voting took place by postal ballot.

Researchers discover SARS-CoV-2 inhibitors

A research team of pharmacists at the University of Bonn has discovered two families of active substances that can block the replication of the SARS-CoV-2 coronavirus. The drug candidates are able to switch off the the key enzyme of the virus, the so-called main protease. The study is based on laboratory experiments. Extensive clinical trials are still required for their further development as therapeutic drugs. The results have now been published in the journal "Angewandte Chemie".
