Observation of an Excited Omega(-) Baryon
(American Physical Society, 2018-08-02)
Using data recorded with the Belle detector, we observe a new excited hyperon, an Omega*(-) candidate decaying into Xi K-0(-) and Xi K--(S)0 with a mass of 2012.4 +/- 0.7(stat) +/- 0.6(syst) McV/c(2) and a width of Gamma ...
University Social Responsibility towards Engineering Undergraduates: The Effect of Methodology on a Service-Learning Experience
(MDPI, 2018-06)
Service-Learning (SL) experiences enable University Social Responsibility (USR) to be worked on in engineering studies as a core of education for Sustainability. The combined use of such experiences with active student-centered ...
Analysis of the Process Parameter Influence in Laser Cladding of 316L Stainless Steel
(MDPI, 2018-09)
Laser Cladding is one of the leading processes within Additive Manufacturing technologies, which has concentrated a considerable amount of effort on its development. In regard to the latter, the current study aims to ...
iPS Cell Cultures from a Gerstmann-Sträussler-Scheinker Patient with the Y218N PRNP Mutation Recapitulate tau Pathology
(Humana Press, 2018-04)
Gerstmann-Straussler-Scheinker (GSS) syndrome is a fatal autosomal dominant neurodegenerative prionopathy clinically characterized by ataxia, spastic paraparesis, extrapyramidal signs and dementia. In some GSS familiar ...
Formation of Surface and Quantum-Well States in Ultra Thin Pt Films on the Au(111) Surface
(MDPI, 2017-12-09)
The electronic structure of the Pt/Au(111) heterostructures with a number of Pt monolayers n ranging from one to three is studied in the density-functional-theory framework. The calculations demonstrate that the deposition ...
The Mimetic Born-Infeld Gravity: The Primordial Cosmos and Spherically Symmetric Solutions
(MDPI, 2017-11-27)
The Eddington-inspired-Born-Infeld (EiBI) model is reformulated within the mimetic approach. In the presence of a mimetic field, the model contains non-trivial vacuum solutions. We study a realistic primordial vacuum ...
Retained Austenite Control for the Soft Machining of High-Hardness Tool Steels
(MDPI, 2018-07-23)
Most high-hardness tool steels comprising forming dies require expensive finish machining operations to compensate for the dimensional distortion and surface oxidation caused by the die heat treatment. Precipitation-hardening ...
Quantum-Gravitational Effects on Primordial Power Spectra in Slow-Roll Inflationary Models
(MDPI, 2018-01-08)
We review the computation of the power spectra of inflationary gauge-invariant perturbations in the context of canonical quantum gravity for generic slow-roll models. A semiclassical approximation, based on an expansion ...
Development, characterization and comparisons of targeted and non-targeted metabolomics methods
(Public Library Science, 2018-11-15)
The potential of a metabolomics method to detect statistically significant perturbations in the metabolome of an organism is enhanced by excellent analytical precision, unequivocal identification, and broad metabolomic ...
A redox-active radical as an effective nanoelectronic component: stability and electrochemical tunnelling spectroscopy in ionic liquids
(Royal Society of Chemistry, 2016-10-28)
A redox-active persistent perchlorotriphenylmethyl (PTM) radical chemically linked to gold exhibits stable electrochemical activity in ionic liquids. Electrochemical tunnelling spectroscopy in this medium demonstrates that ...
