Elevated expression of ANTXR1 gene in tumors is a poor prognostic biomarker for patients with bladder cancer

Frontiers in Molecular Biosciences
The TEM8 protein coded by the ANTXR1 gene represents an emerging biomarker in solid tumors. In addition to the various roles TEM8 plays in oncogenesis, including angiogenesis, epithelial-to-mesenchymal transition, and cell migration, it has also been ...

Family of Bell inequalities violated by higher-dimensional bound entangled states [PDF]

, 2017
We construct ($d\times d$)-dimensional bound entangled states, which violate, for any $d>2$, a bipartite Bell inequality introduced in this paper. We conjecture that the proposed class of Bell inequalities acts as a dimension witness for bound entangled ...

Does a large quantum Fisher information imply Bell correlations?

, 2019
The quantum Fisher information (QFI) of certain multipartite entangled quantum states is larger than what is reachable by separable states, providing a metrological advantage.

Quantum tomographic cryptography with Bell diagonal states: non-equivalence of classical and quantum distillation protocols [PDF]

, 2004
We present a generalized tomographic quantum key distribution protocol in which the two parties share a Bell diagonal mixed state of two qubits. We show that if an eavesdropper performs a coherent measurement on many quantum ancilla states simultaneously,

Heterogeneous multipartite entanglement purification for size-constrained quantum devices

Physical Review Research, 2021
The entanglement resource required for quantum information processing comes in a variety of forms, from Bell states to multipartite GHZ states or cluster states.

Complete hyperentangled-Bell-state analysis for quantum communication

, 2011
It is impossible to unambiguously distinguish the four Bell states in polarization, resorting to linear optical elements only. Recently, the hyperentangled Bell state, the simultaneous entanglement in more than one degree of freedom, has been used to ...

Ready-to-eat cereal consumption is associated with improved nutrient intakes and diet quality in Canadian adults and children across income levels

Frontiers in Nutrition
BackgroundResults from observational studies suggest ready-to-eat cereal (RTEC) consumption is associated with higher diet quality. In the United States, studies have shown that RTEC is an important contributor to nutrient intakes across income levels ...

Two-axis two-spin squeezed states

Physical Review Research, 2020
The states generated by the two-spin generalization of the two-axis countertwisting Hamiltonian are examined. We analyze the behavior at both short and long timescales, by calculating various quantities such as squeezing, spin expectation values ...

Gisin's Theorem for Arbitrary Dimensional Multipartite States

, 2010
We present a set of Bell inequalities which are sufficient and necessary for separability of general pure multipartite quantum states in arbitrary dimensions. The relations between Bell inequalities and distillability are also studied.

Functional Bell inequalities can serve as a stronger entanglement witness [PDF]

, 2002
We consider a Bell inequality for a continuous range of settings of the apparatus at each site. This "functional" Bell inequality gives a better range of violation for generalized GHZ states.
