On the Significance of the Quantum Mechanical Covariance Matrix

Entropy, 2018
The characterization of quantum correlations, being stronger than classical, yet weaker than those appearing in non-signaling models, still poses many riddles.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Finitely Additive Equivalent Martingale Measures [PDF]

Let L be a linear space of real bounded random variables on the probability space (omega,A, P0). There is a finitely additive probability P on A, such that P tilde P0 and EP (X) = 0 for all X in L, if and only if cEQ(X) = ess sup(-X), X in L, for some ...

The action cost of information: A structural framework for quantum contextuality

Physics Open
Quantum contextuality can be viewed as an information-capacity signature of a structural limitation on physical distinguishability. We adopt, as a working principle, a coherence threshold formulated in terms of prequantum holonomy: physically ...

Squashed quantum non-Markovianity: a measure of genuine quantum non-Markovianity in states [PDF]

Quantum
Quantum non-Markovianity in tripartite quantum states $\rho_{ABC}$ represents a correlation between systems $A$ and $C$ when conditioned on the system $B$ and is known to have both classical and quantum contributions.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Shackle versus Savage: non-probabilistic alternatives to subjective probability theory in the 1950s [PDF]

G.L.S Shackle’s rejection of the probability tradition stemming from Knight's definition of uncertainty was a crucial episode in the development of modern decision theory.

A Philosophical Foundation of Non-Additive Measure and Probability [PDF]

, 2018
In this paper, non-additivity of a set function is interpreted as a method to express relations between sets which are not modeled in a set theoretic way.

Fock States in Additive Gaussian Noise Channels: Analytical and Numerical Considerations

IET Quantum Communication
In this paper, we study the effects of additive Gaussian noise on Fock states. We put forth a simple analytical formula for the resulting output states.
