    Revisiting Large Neutrino Magnetic Moments

    Full text link
    Current experimental sensitivity on neutrino magnetic moments is many orders of magnitude above the Standard Model prediction. A potential measurement of next-generation experiments would therefore strongly request new physics beyond the Standard Model. However, large neutrino magnetic moments generically tend to induce large corrections to the neutrino masses and lead to fine-tuning. We show that in a model where neutrino masses are proportional to neutrino magnetic moments. We revisit, discuss and propose mechanisms that still provide theoretical consistent explanations for a potential measurement of large neutrino magnetic moments. We find only two viable mechanisms to realize large transition magnetic moments for Majorana neutrinos only.Comment: 12 pages, 7 figure

    On Continuous Magnetically Enhanced Centrifugation in Large Scale Downstream Processing of Bioproducts

    The current thesis targets on the technical use of Magnetically Enhanced Centrifugation (MEC). Aim is the understanding of the mechanisms of particle transport out of the magnetic field by simulations of the phenomena, and the realization of MEC in a large scale. Industrial scale machines for batch-wise and continuous discharge were tested. The use of synthetic magnetic particles with functionalized surface allows the separation of non-magnetic matter

    The EU budget – how much scope for institutional reform?

    Get PDF
    This paper reviews current discussions on reforming the European Union (EU) budgetary procedure and assesses the main reform proposals that have been suggested thus far. It argues that prospects for reforms are presently hampered by the complex interplay between supranational and intergovernmental decision modes and the requirement of any budgetary procedure to strike a balance between efficiency and legitimacy. The paper reviews the main criticisms of the present budgetary procedure and the related reform proposals, which are assessed on the basis of relevant theoretical literature as well as brief comparisons with the federal budget of the United States. The paper argues that the current EU budgetary procedure matches by-and-large the current equilibrium between all actors involved, given the present state of political integration in the EU. Significant modifications to the budgetary procedure would depart from that equilibrium.European Union, EU budget, budget process

It argues that prospects for reforms are presently hampered by the complex interplay between supranational and intergovernmental decision modes and the requirement of any budgetary procedure to strike a balance between efficiency and legitimacy. The paper reviews the main criticisms of the present budgetary procedure and the related reform proposals, which are assessed on the basis of relevant theoretical literature as well as brief comparisons with the federal budget of the United States. The paper argues that the current EU budgetary procedure maximises efficiency and legitimacy, given the present state of political integration in the EU. Significant modifications to the budgetary procedure would depart from that equilibrium.

    Density of Ideal Lattices

    The security of many emph{efficient} cryptographic constructions, e.g.~collision-resistant hash functions, digital signatures, and identification schemes, has been proven assuming the hardness of emph{worst-case} computational problems in ideal lattices. These lattices correspond to ideals in the ring of integers of some fixed number field KK. In this paper we show that the density of nn-dimensional ideal lattices with determinant leble b among all lattices under the same bound is in O(b1−n)O(b^{1-n}). So for lattices of dimension >1> 1 with bounded determinant, the subclass of ideal lattices is always vanishingly small

    Introducing data-format-dependent road network conversion techniques – lessons learned from the digital twin Munich

    Get PDF
    The Digital Twin Munich project (DZ-M) aims to depict complex urban environments through the use of static and dynamic components, and their semantic relationships. The project focuses on the development of a street network model and urban mobility simulation, utilizing the open source microscopic traffic flow simulation software SUMO. The transport demand is provided by the VISUM model of the city of Munich, and the data structure developed is compatible with standards such as OpenStreetMap, OpenDrive, CityGML, and GTFS. The project also includes the use of physical VRU simulators for data collection purposes, and the integration of these simulations into a 3D VR environment in Unity

    Investigating Lane-Free Traffic with a Dynamic Driving Simulator

    Full text link
    Lane-free traffic (LFT) is a new traffic system that relies on connected and automated vehicles (CAV) to increase road capacity and utilization by removing traditional lane markings using coordinated maneuvering of CAVs in LFT strategies. LFT is based on two main principles: upstream nudging and vehicles moving without adhering to any lane markings. By leveraging CAV capabilities to communicate and exchange information, LFT represents a promising future traffic system. While current research uses LFT simulations in two-dimensional space, driving simulators are necessary to investigate human behavior and perceived safety in LFT. This paper proposes a conceptual framework for LFT driving simulations and describes the assumptions, requirements, and recent technological developments that make it possible to investigate the human perspective and acceptance of LFT. Additionally, we propose a scenario matrix that can act as a test guide to building driving simulation scenarios for the LFT.Comment: This paper was presented at IEEE ITSC 202
