REE characteristics of the coal in the Erlian Basin, Inner Mongolia, China, and its economic value
China Geology, 2021 The rare earth elements (REE) content of the coal in the Erlian Basin was determined by inductively coupled plasma mass spectrometry (ICP-MS), and it turns out that the REE content from different geological age shows a significant difference: The REE ...

Comparison of the relative entropy of entanglement and negativity
, 2008 It is well known that for two qubits the upper bounds of the relative entropy of entanglement (REE) for a given concurrence as well as the negativity for a given concurrence are reached by pure states. We show that, by contrast, there are two-qubit mixed

Distribution and origin of major and trace elements (particularly REE, U and Th) into labile and residual phases in an acid soil profile (Vosges Mountains, France). [PDF]
, 2004 A seven step sequential extraction procedure has been conducted on a podzolic soil profile from the Vosges Mountains in order to determine the ability of several elements to be released to the environment.

Beyond the Non‐Hermitian Skin Effect: Scaling‐Controlled Topology from Exceptional‐Bound Bands
Advanced Science, EarlyView.ABSTRACT We establish a novel mechanism for topological transitions in non‐Hermitian systems that are controlled by the system size. Based on a new paradigm known as exceptional‐bound (EB) band engineering, its mechanism hinges on the unique critical scaling behavior near an exceptional point, totally unrelated to the well‐known non‐Hermitian skin ...

Integrated environmental risk assessment of rare earth elements mixture on aquatic ecosystems
Frontiers in Environmental Science, 2022 Rare Earth elements (REE) have become essential in strategical sectors such as high- and green-technologies. Their increasing use in human activities worldwide leads to anthropogenic REE releases detectable in all compartments of the environment ...

Towards an Entanglement Measure for Mixed States in CFTs Based on Relative Entropy [PDF]
, 2018 Relative entropy of entanglement (REE) is an entanglement measure of bipartite mixed states, defined by the minimum of the relative entropy $S(\rho_{AB}|| \sigma_{AB})$ between a given mixed state $\rho_{AB}$ and an arbitrary separable state $\sigma_{AB}$

Australian Journal of Social Issues, EarlyView.ABSTRACT Diagnoses of autism spectrum disorder in Australia have increased considerably in recent years. The current study investigated how the National Disability Insurance Scheme (NDIS) impacts quality of life (QoL) among carers of children with autism spectrum disorder.
