Published in 2020 at "American Journal of Hematology"

DOI: 10.1002/ajh.25746

Abstract: We evaluated bone marrow minimal residual disease (MRD) negativity in 44 patients with light chain (AL) amyloidosis using next generation flow cytometry (sensitivity ≥1 × 10−5; median events analyzed: 8.7 million, range: 4.8 to 9.7 million). All… read more here.

Published in 2021 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-020-04687-8

Abstract: Based on the solvable dynamical model for quantum measurement process, we consider three uncoupled particles interacting with their local one-dimensional (1D) spin arrays. Here the 1D spin arrays can be regarded as the local phase… read more here.

Published in 2019 at "Quantum Information Processing"

DOI: 10.1007/s11128-018-2121-5

Abstract: Quantum coherence and entanglement are two key features in quantum mechanics and play important roles in quantum information processing and quantum computation. We provide a general triangle-like inequality satisfied by the $$l_1$$l1-norm measure of coherence… read more here.

Published in 2019 at "Quantum Information Processing"

DOI: 10.1007/s11128-019-2223-8

Abstract: The k-ME concurrence as a measure of multipartite entanglement (ME) unambiguously detects all k-nonseparable states in arbitrary dimensions and satisfies many important properties of an entanglement measure. Negativity is a simple computable bipartite entanglement measure.… read more here.

Published in 2019 at "Nature Human Behaviour"

DOI: 10.1038/s41562-019-0766-4

Abstract: Across seven experiments and one survey ( n  = 4,282), people consistently overestimated out-group negativity towards the collective behaviour of their in-group. This negativity bias in group meta-perception was present across multiple competitive (but not cooperative)… read more here.

Published in 2018 at "New Journal of Physics"

DOI: 10.1088/1367-2630/aad9ba

Abstract: Entanglement has developed into an essential concept for the characterization of phases and phase transitions in ground states of quantum many-body systems. In this work, we use the logarithmic negativity to study the spatial entanglement… read more here.

Published in 2020 at "Journal of Physics A: Mathematical and Theoretical"

DOI: 10.1088/1751-8121/ab831c

Abstract: We consider a quench in a free-fermion chain by joining two homogeneous half-chains via a defect. The time evolution of the entanglement negativity is studied between adjacent segments surrounding the defect. In case of equal… read more here.

Published in 2021 at "BJS Open"

DOI: 10.1093/bjsopen/zrab040

Abstract: Abstract Background Oestrogen receptor (ER) status provides invaluable prognostic and therapeutic information in breast cancer (BC). When clinical decision making is driven by ER status, the value of progesterone receptor (PgR) status is less certain.… read more here.

Published in 2019 at "The Gerontologist"

DOI: 10.1093/geront/gny013

Abstract: PURPOSE Parents' and children's lives are interwoven over the life course. Parents' positivity and negativity toward children relate to children's and parents' transitions, although the nature of this relationship is unclear. This study investigated the… read more here.

Published in 2019 at "Physical Review A"

DOI: 10.1103/physreva.100.063808

Abstract: In a numerical study, we investigate the steady-state generation of nonclassical states of light from a coherently driven two-level atom in a one-dimensional waveguide. Specifically, we look for states with a negative Wigner function, since… read more here.

Published in 2019 at "Physical Review A"

DOI: 10.1103/physreva.99.012322

Abstract: Negativity is an entanglement monotone frequently used to quantify entanglement in bipartite states. Because negativity is a non-analytic function of a density matrix, existing methods used in the physics literature are insufficient to compute its… read more here.
