Operation strategies guideline for packed bed thermal energy storage systems
(Wiley, 2019)
Artículo / Artikulua,
Packed bed thermal energy storage (TES) systems have been identified in the last years as one of the most promising TES alternatives in terms of thermal efficiency and economic viability. The relative simplicity of this ...
Double-port slotted-antenna with multiple miniaturized radiators for wideband wireless communication systems and portable devices
(Electromagnetics Academy, 2019)
info:eu-repo/semantics/article,
Proof-of-concept is presented of a novel slot antenna structure with two excitation ports. Although this antenna provides a wide impedance bandwidth, its peak gain and optimum radiation efficiency are observed at its ...
High-isolation leaky-wave array antenna based on CRLH-metamaterial implemented on SIW with ±30° frequency beam-scanning capability at millimetre-waves
(MDPI, 2019)
info:eu-repo/semantics/article,
The paper presents a feasibility study on the design of a new metamaterial leaky-wave antenna (MTM-LWA) used in the construction of a 1 × 2 array which is implemented using substrate-integrated waveguide (SIW) technology ...
Noncontiguous operon is a genetic organization for coordinating bacterial gene expression
(National Academy of Sciences, 2019)
info:eu-repo/semantics/article,
Bacterial genes are typically grouped into operons defined as clusters of adjacent genes encoding for proteins that fill related roles and are transcribed into a single polycistronic mRNA molecule. This simple organization ...
On fixed point theory in partially ordered sets and an application to asymptotic complexity of algorithms
(Springer, 2019)
info:eu-repo/semantics/article,
The celebrated Kleene fixed point theorem is crucial in the mathematical modelling of recursive specifications in Denotational Semantics. In this paper we discuss whether the hypothesis of the aforementioned result can be ...
Geometric multigrid methods for Darcy–Forchheimer flow in fractured porous media
(Elsevier, 2019)
info:eu-repo/semantics/article,
In this paper, we present a monolithic multigrid method for the efficient solution of flow problems in fractured porous media. Specifically, we consider a mixed-dimensional model which couples Darcy flow in the porous ...
Experimental investigation of the particle oscillation instability in a single-axis acoustic levitator
(AIP Publishing, 2019)
info:eu-repo/semantics/article,
Single-axis acoustic levitators are employed in biomedicine, chemistry and physics experiments due to their ability to trap in mid-air objects of a wide range of materials and sizes. Although this type of levitator has ...
New approach to suppress mutual coupling between longitudinal-slotted arrays based on SIW antenna loaded with metal-fences working on VHF/UHF frequency-bands: study, investigation, and principle
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work it is demonstrated that substrate integrated waveguide longitudinal slotted array antenna (SIWLSAA) which is loaded with metal fences exhibits high-isolation across VHF/UHF bands. A reference SIWLSAA used for ...
Hepatocyte-specific loss of GPS2 in mice reduces non-alcoholic steatohepatitis via activation of PPARα
(Nature Research, 2019)
Artículo / Artikulua,
Obesity triggers the development of non-alcoholic fatty liver disease (NAFLD), which involves alterations of regulatory transcription networks and epigenomes in hepatocytes. Here we demonstrate that G protein pathway ...
ENSO and NAO affect long-term leaf litter dynamics and stoichiometry of Scots pine and European beech mixedwoods
(Wiley, 2019)
Artículo / Artikulua,
Litterfall dynamics (production, seasonality and nutrient composition) are key factors influencing nutrient cycling. Leaf litter characteristics are modified by species composition, site conditions and water availability. ...
