Equivalent Formulation of Thomassen's Conjecture Using Tutte Paths in Claw‐Free Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We continue studying Thomassen's conjecture (every 4‐connected line graph has a Hamilton cycle) in the direction of a recently shown equivalence with Jackson's conjecture (every 2‐connected claw‐free graph has a Tutte cycle), and we extend the equivalent formulation as follows: In every connected claw‐free graph, any two vertices are connected

Abbreviated MRI and Ultrafast MRI of the Breast

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Detection of breast cancer in MRI requires fast, dynamic contrast enhanced (DCE) imaging covering the immediate post‐contrast phase, that is, the first 60 s after contrast injection. This ensures selective depiction of invasive cancer as well as DCIS against an otherwise dark background, that is, before background parenchymal enhancement (BPE)

Assessment of Glucose Metabolism in Vivo in the Human Frontal Lobe Using Interleaved 1H and 13C MRS at 7T

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background 13C magnetic resonance spectroscopy (MRS), combined with 13C‐labeled substrate infusion, offers a nonionizing, minimally invasive method for assessing fluxes through the main cerebral energy metabolism pathways. However, its human application at 7T has not been fully established, especially within the frontal lobe, where alterations

Ambivalence at the Helm: How the Positive Effect of Ambivalence to Lead on Leader Integrative Complexity Affects Leaders' Effectiveness

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT We study the phenomenon of ambivalence to lead, characterized as leaders' experience of mixed feelings (positive and negative) toward their leadership position. We do so by integrating the beneficial role of dualities with the affect‐as‐information theory.
