Stabilization of the perovskite phase in the Y-Bi-O system by using a BaBiO3_{3} buffer layer

A topological insulating phase has theoretically been predicted for the thermodynamically unstable perovskite phase of YBiO$_{3}$. Here, it is shown that the crystal structure of the Y-Bi-O system can be controlled by using a BaBiO$_{3}$ buffer layer. The BaBiO$_{3}$ film overcomes the large lattice mismatch of 12% with the SrTiO$_{3}$ substrate by forming a rocksalt structure in between the two perovskite structures. Depositing an YBiO$_{3}$ film directly on a SrTiO$_{3}$ substrate gives a fluorite structure. However, when the Y-Bi-O system is deposited on top of the buffer layer with the correct crystal phase and comparable lattice constant, a single oriented perovskite structure with the expected lattice constants is observed.Comment: 8 pages, 7 figures + 4 pages supporting informatio

How transnational stakeholders impact multinational corporations in the context of globalization

Stakeholder theory faces two closely related challenges in the light of globalization. On the one hand, globalization has not only led many firms to explore and expand into different parts of the world, it has also created possibilities for non-traditional stakeholders to ‘knock on the doors’ of firms and make their concerns heard. On the other hand, the context of the multitude and complexity of novel stakeholder relationships that were not usually considered in stakeholder mappings renders the issue of corporate responsibility even more ‘political’ than stakeholder relationships have always been. However, exactly how such non-traditional stakeholders knock on the firms’ doors has insufficiently been explored in stakeholder theorizing. Stakeholder theory appears to have difficulty in explaining the potential leverage that stakeholder groups without a clear and direct stake in a firm may exert over that particular firm. We propose to speak of ‘boomerang politics’ as a general and overarching term in order to advance stakeholder theory in the light of the challenges from globalization by exploring how non-traditional stakeholders knock on firms’ doors

From code to clinic: theory and practice for artificial intelligence prediction algorithms

This thesis looks at Artificial Intelligence (AI) and its potential to revolutionise the healthcare sector. The first part of this thesis focuses on the responsible development and validation of AI-based clinical prediction algorithms, exploring the prime considerations in this process. The second part of this thesis addresses the opportunities for classical statistics and machine learning techniques for developing prediction algorithms. It also examines the performance, potential, and challenges of AI prediction algorithms for clinical practice. The conclusion states that cross-discipline collaboration, exchangeability of knowledge and results, and validation of AI for healthcare practice are essential for realising the potential of AI in healthcare.LUMC / Geneeskund

Characterizing the local vectorial electric field near an atom chip using Rydberg state spectroscopy

We use the sensitive response to electric fields of Rydberg atoms to characterize all three vector components of the local electric field close to an atom-chip surface. We measured Stark-Zeeman maps of $S$ and $D$ Rydberg states using an elongated cloud of ultracold Rubidium atoms ($T\sim2.5$ $\mu$K) trapped magnetically $100$ $\mu$m from the chip surface. The spectroscopy of $S$ states yields a calibration for the generated local electric field at the position of the atoms. The values for different components of the field are extracted from the more complex response of $D$ states to the combined electric and magnetic fields. From the analysis we find residual fields in the two uncompensated directions of $0.0\pm0.2$ V/cm and $1.98\pm0.09$ V/cm respectively. This method also allows us to extract a value for the relevant field gradient along the long axis of the cloud. The manipulation of electric fields and the magnetic trapping are both done using on-chip wires, making this setup a promising candidate to observe Rydberg-mediated interactions on a chip.Comment: 8 pages, 5 figure
