Magnetic regulation of the luminescence of hybrid lanthanide-doped nanoparticles

The unique optical properties of lanthanide-doped nanomaterials have made them broadly attractive to a wide range of applications in chemical, physical, and biomedical fields. As an external and real-time reg-ulation tool, the magnetic field is highly usef ...

A hybrid erbium(III)-bacteriochlorin near-infrared probe for multiplexed biomedical imaging

Jean-Claude Bünzli, Fan Zhang, Ting Wang, Zhiyong Liu

Spectrally distinct fluorophores are desired for multiplexed bioimaging. In particular, monitoring biological processes in living mammals needs fluorophores that operate in the 'tissue-transparent' near-infrared (NIR) window, that is, between 700 and 1,700 ...

Voyager 2 plasma observations of the heliopause and interstellar medium

Paula Garcia Galindo

The solar wind blows outwards from the Sun and forms a bubble of solar material in the interstellar medium. The heliopause (HP) is the boundary that divides the hot tenuous solar wind plasma in the heliosheath from the colder, denser very local interstella ...

Analysis of runaway electron expulsion during tokamak instabilities detected by a single-channel Cherenkov probe in FTU

Cristian Galperti, Gabriele Grosso, Filippo Bagnato

The expulsion of runaway electrons (REs) during different types of tokamak instabilities is analysed by means of a Cherenkov probe inserted into the scrape-off layer of the FTU tokamak. One such type of instability, the well-known tearing mode, is involved ...

Two-fluid solutions for Langmuir probes in collisionless and isothermal plasma, over all space and bias potential

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne

This paper presents solutions for the classical one-dimensional (1D radial and Cartesian) problem of Langmuir probes in a collisionless, isothermal plasma. The method is based on two-fluid equations derived from the first two moments of Vlasov's equation. ...

Superdiffusive transport in laboratory and astrophysical plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

In the last few years it has been demonstrated, both by data analysis and by numerical simulations, that the transport of energetic particles in the presence of magnetic turbulence can be superdiffusive rather than normal diffusive (Gaussian). The term ‘su ...

Boundary conditions for plasma fluid models at the magnetic presheath entrance

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern

The proper boundary conditions at the magnetic presheath entrance for plasma fluid turbulence models based on the drift approximation are derived, focusing on a weakly collisional plasma sheath with Ti≪Te and a magnetic field oblique to a totally absorbing ...

Existence of subsonic plasma sheaths

Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella

The location of the plasma sheath edge, where quasineutrality is broken, is rigorously derived by using a kinetic description of the plasma. It is shown that sheaths can exist with arbitrarily small ion velocity at the sheath edge, thus violating the Bohm ...

SeTraStream: Semantic-Aware Trajectory Construction over Streaming Movement Data

Zhixian Yan

Location data generated from GPS equipped moving objects are typically collected as streams of spatio-temporal (x,y,t) points that when put together form corresponding {\em trajectories}. Most existing studies focus on building ad-hoc querying, analysis, a ...
