Objective: This study evaluated the capability of a MALDI Biotyper system equipped with the newly introduced MBT STAR-BL module to simultaneously perform species identification and β-lactamase-mediated resistance detection in bacteremia -causing bacteria isolated from cultured isolates and patient-derived blood cultures (BCs). Methods: Two hundred retrospective cultured isolates and 153 prospec...
A tight binding approach based on the Bogoliubov-de Gennes approach has been used to calculate the DC Josephson current for a lattice model for S-GNR-S junctions , for short junctions with respect to superconducting coherence length. We calculate the phase, length, width and chemical potential dependence at the Josephson junction and discuss the similarities and differences with regard to the t...
BACKGROUND Pseudomonas aeruginosa is an uncommon cause of community-acquired bacteremia among patients without severe immunodeficiency. Because tension exists between the need to limit unnecessary use of anti-pseudomonal agents and the need to avoid a delay in appropriate therapy, clinicians require better guidance regarding when to cover empirically for P. aeruginosa. We sought to determine th...
PURPOSE To examine the novel application of a commercially available optical coherence tomography (OCT) system toward molecular histopathology using gold nanorod (GNR) linked antibodies as a functionalized contrast agent to evaluate ocular surface squamous neoplasia (OSSN). METHODS GNRs were synthesized and covalently attached to anti-glucose transporter-1 (GLUT-1) antibodies via carbodiimide...
Topological theory has been recently applied in graphene nanoribbons (GNRs) and predicts the existence of topological quantum states junctions connecting GNRs different classes. Through periodic alignment along a GNR backbone, frontier electronic bands with tunable band gaps widths could be generated. In this work, we demonstrate evolution by fabricating structures hosting single junction, dime...
Abstract Lateral heterojunctions of atomically precise graphene nanoribbons (GNRs) hold promise for applications in nanotechnology, yet their charge transport and most the spectroscopic properties have not been investigated. Here, we synthesize a monolayer multiple aligned consisting quasi-metallic wide-bandgap GNRs, report characterization by scanning tunneling microscopy, angle-resolved photo...
Strain can tailor the band structures and properties of graphene nanoribbons (GNRs) with well-known emergent pseudo-magnetic fields corresponding pseudo-Landau levels (pLLs). We design one type zigzag GNR (ZGNR) reverse strains, producing opposite signs in lower upper half planes. Therefore, electrons propagate along interface as "snake states", experiencing Lorentz forces they cross zero field...
