Racetrack potentials and the de Sitter swampland conjectures
(Springer, 2019-01)
We show that one can find de Sitter critical points (saddle points) in models of flux compactification of Type IIB String Theory without any uplifting terms and in the presence of several moduli. We demonstrate this by ...
On Some Sufficiency-Type Stability and Linear State-Feedback Stabilization Conditions for a Class of Multirate Discrete-Time Systems
(MDPI, 2018-05)
This paper presents and discusses the stability of a discrete multirate sampling system whose sets of sampling rates (or sampling periods) are the integer multiple of those operating on all the preceding substates. Each ...
Waterborne Acrylate-Based Hybrid Coatings with Enhanced Resistance Properties on Stone Surfaces
(MDPI, 2018-08)
The application of coating polymers to building materials is a simple and cheap way to preserve and protect surfaces from weathering phenomena. Due to its environmentally friendly character, waterborne coating is the most ...
The effect of the evaporation rate on electrochemical measurements with paper-based analytical devices and its minimisation by enclosure with adhesive tape
(Elsevier, 2019-02-15)
In this work, the effect of liquid evaporation on electrochemical measurements with electrochemical paper-based devices (ePADs) is studied. The time evolution of cyclic voltammograms of ferricyanide is used to study the ...
Polyacrylamide Ferrogels with Magnetite or Strontium Hexaferrite: Next Step in the Development of Soft Biomimetic Matter for Biosensor Applications
(MDPI, 2018-01-16)
Magnetic biosensors are an important part of biomedical applications of magnetic materials. As the living tissue is basically a " soft matter." this study addresses the development of ferrogels (FG) with micron sized ...
Transparent Glass-Ceramics Produced by Sol-Gel: A Suitable Alternative for Photonic Materials
(MDPI, 2018-01-30)
Transparent glass-ceramics have shown interesting optical properties for several photonic applications. In particular, compositions based on oxide glass matrices with fluoride crystals embedded inside, known as oxyfluoride ...
Human Early Life Exposome (HELIX) study: a European population-based exposome cohort
(BMJ, 2018-09)
Purpose Essential to exposome research is the collection of data on many environmental exposures from different domains in the same subjects. The aim of the Human Early Life Exposome (HELIX) study was to measure and describe ...
Modification of a Shockley-Type Surface State on Pt(111) upon Deposition of Gold Thin Layers
(MDPI, 2018-12-17)
We present a first-principles fully-relativistic study of surface and interface states in the n one monolayer (ML) Au/Pt(111) heterostructures. The modification of an unoccupied s - p -type surface state existing on a ...
High- fi delity non-adiabatic cutting and stitching of a spin chain via local control
(IOP Publishing, 2018-10-18)
We propose and analyze, focusing on non-adiabatic effects, a technique of manipulating quantum spin systems based on local 'cutting' and 'stitching' of the Heisenberg exchange coupling between the spins. This first operation ...
Neural substrates of subphonemic variation and lexical competition in spoken word recognition
(Language, Cognition and Neuroscience, 2019)
In spoken word recognition, subphonemic variation influences lexical activation, with sounds near a category boundary increasing phonetic competition as well as lexical competition. The current study investigated the ...
