Asymmetry and coherence weight of quantum states

open access: yes, 2018
The asymmetry of quantum states is an important resource in quantum information processing tasks such as quantum metrology and quantum communication. In this paper, we introduce the notion of $asymmetry~weight$ --- an operationally motivated asymmetry ...

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Observation of inter-Landau-level quantum coherence in semiconductor quantum wells

open access: yes, 2008
Using three-pulse four-wave-mixing femtosecond spectroscopy, we excite a non-radiative coherence between the discrete Landau levels of an undoped quantum well and study its dynamics.

Remote Monitoring in Myasthenia Gravis: Exploring Symptom Variability

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Myasthenia gravis (MG) is a rare, autoimmune disorder characterized by fluctuating muscle weakness and potential life‐threatening crises. While continuous specialized care is essential, access barriers often delay timely interventions. To address this, we developed MyaLink, a telemedical platform for MG patients.

Davison on Skepticism: How not to Respond to the Skeptic

open access: yesPrincipia: An International Journal of Epistemology, 2005
In his defense of a coherence theory of truth and knowledge, Donald Davidson insists that (i) we must take the objects of a belief to be the causes of that belief, and (ii) given the nature of beliefs, most of our be-liefs are veridical.

Coherence of assistance and assisted maximally coherent states

open access: yesScientific Reports, 2021
Coherence and entanglement are fundamental concepts in resource theory. The coherence (entanglement) of assistance is the coherence (entanglement) that can be extracted assisted by another party with local measurement and classical communication.

A Corrective to Bovens and Hartmann's Measure of Coherence [PDF]

open access: yes, 2004
Bovens and Hartmann (2003a, 2003b) propose to analyze coherence as a confidence-boosting property. On the basis of this idea, they construct a new probabilistic theory of coherence.

Diffusion Spectrum Imaging Maps Early Axonal Loss and a Unique Progressive Signal in Neuronal Intranuclear Inclusion Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To delineate specific in vivo white matter pathology in neuronal intranuclear inclusion disease (NIID) using diffusion spectrum imaging (DSI) and define its clinical relevance. Methods DSI was performed on 42 NIID patients and 38 matched controls.

Maximal coherence and the resource theory of purity

open access: yesNew Journal of Physics, 2018
The resource theory of quantum coherence studies the off-diagonal elements of a density matrix in a distinguished basis, whereas the resource theory of purity studies all deviations from the maximally mixed state. We establish a direct connection between

Korrespondensie of koherensie?

open access: yesKoers : Bulletin for Christian Scholarship, 1991
Apart from the pragmatic , the performative , and the existentialist theorie s of truth, the correspondence theory and the coherence theory of truth are of special importance in any discussion about scientific truth.
