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.

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 ...

Photoluminescence spectrum of an interacting two-dimensional electron gas at \nu=1 [PDF]

, 2005
We report on the theoretical photoluminescence spectrum of the interacting two-dimensional electron gas at filling factor one (\nu=1). We considered a model similar to the one adopted to study the X-ray spectra of metals and solved it analytically using ...
