Ontologies are fundamental tools used with different purposes and with different modalities in different areas and communities. To guarantee the right level of quality, the most widely used ontologies are man-made. However, developing and maintaining them turns out to be extremely time-consuming. For this reason, there are approaches aiming at their automatic construction where ontologies are i...

We have measured W 4f7/2 core-level photoemission spectra from W(110) in the presence of Pd overlayers for coverages up to ∼1 pseudomorphic monolayer (ML). At coverages close to 0.05 ML a striking change in the W core-level spectrum is observed, which we interpret as indicating a long-range lateral effect of 2D Pd islands upon the W electronic structure in both the first and second W layers. As...

1 A bacterial monolayer biofilm is a collection of cells attached to a surface but not to 2 each other. Monolayer formation is initiated when a bacterial cell forms a transient 3 attachment to a surface. While some transient attachments are broken, others 4 transition into the permanent attachments that define the monolayer biofilm. In this 5 work, we describe the results of a large-scale, micr...

This paper describes a physical-organic study of the effect of uncharged, polar, functional groups on the rate of charge transport by tunneling across selfassembled monolayer (SAM)-based large-area junctions of the form AgS(CH2)nM(CH2)mT//Ga2O3/EGaIn. Here Ag is a template-stripped silver substrate, -Mand -T are “middle” and “terminal” functional groups, and EGaIn is eutectic gallium−indium all...

Static energy minimization and Monte Carlo simulation are used to study the effect of external electrostatic fields on the structure of a self−assembled monolayer (SAM) formed by methoxy tri(ethylene glycol) terminated alkanethiol molecules. It is found that fields of the order of 1 V/Å in strength can substantially change the equilibrium configuration of the SAM, making the oxygen atoms of the...
