Reliable Entanglement Detection Under Coarse--Grained Measurements

open access: yes, 2013
We derive reliable entanglement witnesses for coarse--grained measurements on continuous variable systems. These witnesses never return a "false positive" for identification of entanglement, under any degree of coarse graining.

Photothermal Interfacial Evaporation Characteristics of PVA/SA–CNT–Borax Hydrogel

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The desalination of seawater has demonstrated significant potential to use solar‐driven interfacial evaporation technologies due to its sustainability, outstanding productivity, and kindness to the environment. In this paper, a hydrogel interfacial evaporator was produced, with PVA and SA as the base materials. The addition of carbon nanotubes

Heavy spin-2 Dark Matter

open access: yes, 2016
We provide further details on a recent proposal addressing the nature of the dark sectors in cosmology and demonstrate that all current observations related to Dark Matter can be explained by the presence of a heavy spin-2 particle. Massive spin-2 fields

Rational Design Strategies for Stimuli‐Responsive DNAzymes Using Modified and Artificial Nucleotides

open access: yesChemistry – A European Journal, EarlyView.
Activity control of RNA‐cleaving DNAzymes in response to external stimuli has attracted growing interest for applications in DNA‐based diagnostics, therapeutics, and dynamic DNA nanotechnology. This review summarizes rational design strategies for stimuli‐responsive DNAzymes using modified or artificial nucleotides, including split and caged DNAzymes ...

A non-iterative sampling approach using noise subspace projection for EIT

open access: yes, 2012
International audienceThis study concerns the problem of the reconstruction of inclusions embedded in a conductive medium in the context of electrical impedance tomography (EIT), which is investigated within the framework of a non-iterative sampling ...

A 0.35 μm CMOS 17-bit@40-kS/s cascade 2-1 ΣΔ modulator with programmable gain and programmable chopper stabilization [PDF]

open access: yes, 2005
This paper describes a 0.35μm CMOS chopper-stabilized Switched-Capacitor 2-1 cascade ΣDelta; modulator for automotive sensor interfaces. For a better fitting to the characteristics of different sensor outputs, the modulator includes a programmable set of

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Theory of spin precession monitored by laser pulse

open access: yes, 2004
We first predict the splitting of a spin degenerate impurity level when this impurity is irradiated by a circularly polarized laser beam tuned in the transparency region of a semiconductor.

Local existence and uniqueness of regular solutions in a model of tissue invasion by solid tumours [PDF]

open access: yes, 2008
In this paper we consider a nonlinear system of differential equations arising in tumour invasion which has been proposed in [1] M.A.J. Chaplain and A.R.A.

Reviewing and benchmarking ecological modelling practices in the context of land use

open access: yesEcography, EarlyView.
Despite habitat loss and degradation are the primary drivers of biodiversity loss, different conclusions have been drawn about the importance of land‐use or land‐cover (LULC) change for biodiversity. Differences may be due to the difficulty of framing a coherent model design to assess LULC effects.
