Changes in regional cerebral blood flow (rCBF) and glucose metabolism are commonly associated with traumatic brain injury (TBI). Reactive oxygen species (ROS) have been implicated as key contributors to the secondary injury process after TBI. Here, pretreatment with the nitrone radical scavengers (alpha-phenyl-N-tert-butyl nitrone (PBN) or its sulfonated analogue sodium 2-sulfophenyl-N-tert-butyl
At REX-ISOLDE at ISOLDE/CERN radioactive ions are post accelerated with a 10 meters linac for experiments in nuclear-, astro- and solid state physics. For the efficient acceleration to energies between 0.8 and 2.3 MeV/u the principles of charge breeding of radioactive ions by an electron beam source was introduced at REX. The linac in its current stage consists of a 4-rod RFQ, a 20-gap IH drift tu
Autonomous driving is a technology that is currently in a phase of being developed and tested on roads in several countries. A major challenge for autonomous driving and for smart city technologies in general is regulatory challenges both regarding regulation of the technology in itself and technology as a regulator of urban space. This article examines how the development of autonomous driving em
Automatic detection of point groups as well as symmetrisation of molecular geometry and wavefunctions are useful tools in computational quantum chemistry. Algorithms for developing these tools as well as an implementation are presented. The symmetry detection algorithm is a clustering algorithm for symmetry invariant properties, combined with logical deduction of possible symmetry elements using t
We present a rigorous phase noise analysis of a generic harmonic oscillator where the active core can be modeled as a transconductor. Phase noise equations are derived without any specific assumption on the nature of the resonator in the oscillator; furthermore, we provide closed-form 1/f2 phase noise equations when the resonator consists of an arbitrary number of cascaded LC tanks, each tuned at
Two different solutions for the characteristic modes (CMs) of lossy structures were previously developed using induced volume currents. The first solution diagonalizes the scattering and perturbation matrices, guaranteeing far-field orthogonality at the cost of imaginary eigenvalues and eigencurrents. The second solution does not perfectly diagonalize these matrices, but maintains real-valued eige
