Vanadium Dioxide by Atomic Layer Deposition: A Promising Material for Next-Generation Memory Devices.

The synthesis of a vanadium dioxide (VO) film using atomic layer deposition (ALD) with vanadium tetrachloride (VCl) as a precursor for the realization of programmable memory devices is reported. X-ray diffraction analysis revealed the epitaxial growth of VO on c-AlO. The phase transition was monitored using resistivity measurements across varying temperatures, demonstrating a decrease of >4 orders of magnitude at the transition temperature, thereby confirming the high quality of the material.

FUS-mediated BBB opening leads to transient perfusion decrease and inflammation without acute or chronic brain lesion.

The permeabilization of the BBB to deliver therapeutics with MR-guided FUS redefines therapeutic strategies as it improves patient outcomes. To ensure the best translation towards clinical treatment, the evaluation of hemodynamic modifications in the CNS is necessary to refine treatment parameters. MR-guided FUS was applied at 1.

[2003, a year of extremes in Burgundy: pollen counts and meteorological influences].

The year 2003 was marked by some particular meterological situations (mild conditions at the end of winter and during spring) which had consequences on the quantity of pollen in the air during the year. These meteorological influences differ from one taxa to another and mostly from one season to another. These quantities very quite different in comparison with the previous years, in particular a notable increase of many winter and spring tree taxa and a decrease of herbaceous taxa, particularly those pollinating in summer.

[Pollen counts and allergies in Burgundy: profile and perspectives].

The aim of this study was to assess the situation of pollen counts and epidemiological studies on allergies in Burgundy (France), and to talk about the future prospects of this kind of work. Pollen data came from two Hirst traps set up in Dijon and Chalon-sur-Saône, and the medical data (prick-test results) came from an epidemiological study. Pollen counts showed that Betula, Poaceae and Urticaceae were the first pollens in the air.
