Dielectric properties of thin insulating layers measured by Electrostatic Force Microscopy [PDF]

, 2010
In order to measure the dielectric permittivity of thin insulting layers, we developed a method based on electrostatic force microscopy (EFM) experiments coupled with numerical simulations.

Ampicillin-susceptible Enterococcus faecium infections: clinical features, causal clades, and contribution of MALDI-TOF to early detection

Microbiology Spectrum, 2023
Enterococcus faecium, a common resident of the human gastrointestinal tract, is also a major pathogen. Prompt initiation of appropriate treatment is essential to improve patient outcome in disseminated E. faecium infections.

Thermodilution vs estimated Fick cardiac output measurement in an elderly cohort of patients: A single-centre experience [PDF]

, 2019
AIMS: Patients referred to the cath-lab are an increasingly elderly population. Thermodilution (TD, gold standard) and the estimated Fick method (eFM) are interchangeably used in the clinical routine to measure cardiac output (CO).

Nanodielectric mapping of a model polystyrene-poly(vinyl acetate) blend by electrostatic force microscopy [PDF]

, 2010
We present a simple method to quantitatively image the dielectric permittivity of soft materials at nanoscale using electrostatic force microscopy (EFM) by means of the double pass method. The EFM experiments are based on the measurement of the frequency

Intervalley coupling by quantum dot confinement potentials in monolayer transition metal dichalcogenides [PDF]

, 2014
Monolayer transition metal dichalcogenides (TMDs) offer new opportunities for realizing quantum dots (QDs) in the ultimate two-dimensional (2D) limit. Given the rich control possibilities of electron valley pseudospin discovered in the monolayers, this ...

Impact of vancomycin resistance in Enterococcus faecium bloodstream infection on mortality: A retrospective analysis of nationwide surveillance data

International Journal of Infectious Diseases, 2023
Objectives: It is unclear whether the poor outcome of patients with severe vancomycin-resistant enterococci (VRE) infection is attributable to vancomycin resistance or to Enterococcus faecium (Efm), which predominates among VRE.
