Desert navigator: the journey of an ant/ Rüdiger Wehner
No full textIncludes bibliographical references and index"How does a small-brained ant living in the Sahara desert know where it is when searching for prey in the vast expanse of sand and gravel? In Desert Navigator Rudiger Wehner describes and illustrates, in a lively and lucid narrative, how the ants accomplish their navigational tasks by using visual cues in the sky that humans are unable to see, the Earth's magnetic field, the direction of the wind, a step counter, an optic-flow meter and path integrator as well panoramic 'snapshots' of their landmark surroundings, and how they combine all this information to optimally steer their courses. Moreover, a glimpse into the navigator's brain reveals the kind of neural circuitry mediating the observed behavior. Truly, the desert ants have now become model organisms in the study of animal navigation. In telling this discovery story, which he enriches by frequent excursions to other animals and even humans, the author lets us participate in the joys and challenges experienced on a fascinating journey to the desert navigator"--Setting the scene -- The thermophiles -- Finding directions -- Estimating distances -- Integrating paths -- Using landmarks -- Organizing the journey1 online resource (392 pages

Sulzer Innotec AG: Sustainable anchoring of knowledge management in the company
No full textDer Fall Sulzer Innotec AG veranschaulicht Meilensteine und Fallstricke auf dem Weg zu einer konkreten betrieblichen Verankerung von Wissensmanagement. Aus dem Fall lassen sich folgende Erkenntnisse für die Initiierung von Wissensmanagement gewinnen: Eine angemessene Konkretisierung von Wissensmanagement führt über den Weg einer mehrfachen Re-Definition des Themas. Verschiedene Zugänge müssen von allen relevanten Akteuren überprüft und in ihrem wechselseitigen Zusammenhang verstanden und kommuniziert werden. Dabei ist eine längerfristige Perspektive auf Wissensmanagement anzustreben, um einen nachhaltigen Veränderungsprozess zu initiieren. Es bedarf einer breit abgestützten Sensibilisierung von Beteiligten und Betroffenen. Die Zusammenarbeit mit exter¬nen wissenschaftlichen Partnern, die im Rahmen einer Begleitforschung einen interventionsorientierten Ansatz verfolgen, hat sich als prozessunterstützend erwiesen, wobei der methodischen Unterstützung von Sensibilisierungsprozessen für das Thema Wissen eine besondere Bedeutung zukam. Die Institutionalisierung eines Kernteams ermöglichte es, Akteure aus verschiedenen Unternehmensbereichen in den Prozess zu integrieren. Eine zusätzliche, strategische Verankerung des Themas über ein Steering-Committee signalisierte das Commitment des Top-Managements

Quantum resource-saving protocols for early quantum networks
No full textThe Internet as we know it has had an immense impact on the way we communicate. We can now do it faster and more securely than ever before. Enabling quantum communication between any two points on Earth is the next step towards even more secure communication. This is the goal of the quantum internet. Although it is hard to predict all of the applications for the quantum internet, many protocols running on a network connecting nodes able to process qubits have already been identified. Typically, these applications require many qubits to be realized, a requirement which will not likely be met in the early quantum internet.QID/Wehner Grou
SimulaQron—a simulator for developing quantum internet software
No full textWe introduce a simulator of a quantum internet with the specific goal to support software development. A quantum internet consists of local quantum processors, which are interconnected by quantum communication channels that enable the transmission of qubits between the different processors. While many simulators exist for local quantum processors, there is presently no simulator for a quantum internet tailored towards software development. Quantum internet protocols require both classical as well as quantum information to be exchanged between the network nodes, next to the execution of gates and measurements on a local quantum processor. This requires quantum internet software to integrate classical communication programming practises with novel quantum ones. SimulaQron is built to enable application development and explore software engineering practises for a quantum internet. SimulaQron can be run on one or more classical computers to simulate local quantum processors, which are transparently connected in the background to enable the transmission of qubits or the generation of entanglement between remote processors. Application software can access the simulated local quantum processors to execute local quantum instructions and measurements, but also to transmit qubits to remote nodes in the network. SimulaQron features a modular design that performs a distributed simulation based on any existing simulation of a quantum computer capable of integrating with Python. Programming libraries for Python and C are provided to facilitate application development.Accepted Author ManuscriptQID/Wehner GroupQuantum Internet DivisionQuantum Information and Softwar

American conservatism champions individual freedom, limited government, and social and religious traditions. A number of conservatives—including George Will and Peter Wehner—recoil from President Donald Trump, singling out his erosion of the US. Constitution, budget discipline, and the dignity of his office. Wehner and scholar David Hopkins join us to discuss the state of American conservatism today.Jacobs, Lawrence R.; Wehner, Peter; Hopkins, David. (2020).
