(Sage, 2020)Background: Most emergency departments have overcapacity with poor service measured by length of stay. We hypothesized that a formal design of the emergency department production flows will improve service. Thus, we propose ...
-
(MDPI, 2021)Due to its huge impact on the overall quality of service (QoS) of wireless networks, both academic and industrial research have actively focused on analyzing the received signal strength in areas of particular interest. ...
-
(EDP Sciences, 2015)We present a new algorithm designed to improve the signal-to-noise ratio (S/N) of point and extended source detections around bright stars in direct imaging data. One of our innovations is that we insert simulated point ...
-
(Springer Verlag, 2018)This work addresses the study of Chilean Internet robustness in how an outage at the physical layer (Internet backbone) affects the upper layer (BGP network) that routes from/to Internet Service Providers. We propose a ...
-
(2009)Similarity searching in metric spaces has a vast number of applications in several fields like multimedia databases, text retrieval, computational biology, and pattern recognition. In this context, one of the most important ...
-
(Elsevier, 2020)Context: Most modern programming environments support refactorings. Although refactorings are relevant to improve the quality of software source code, they unfortunately suffer from severe usability issues. In particular, ...
-
(2003)The members of a work group need to apply a common strategy to collaboratively solve a problem. A good strategy will mainly depend on the collaboration scenario, participants’ background, and available tools. This ...
-
(2006)This article compares several strategies for searching in Web engines and we present the bucket algorithms to improve the ef ciency of a classical index data structure for parallel textual database. We use the inverted ...
-
(National Academy of Sciences, 2018)Mineral dust aerosols cool Earth directly by scattering incoming solar radiation and indirectly by affecting clouds and biogeochemical cycles. Recent Earth history has featured quasi-100,000-y, glacial-interglacial climate ...
-
(Frontiers Media, 2015)The great phylogenetic diversity of microalgae is corresponded by a wide arrange of interesting and useful metabolites. Nonetheless metabolic engineering in microalgae has been limited, since specific transformation tools ...
-
(Springer New York LLC, 2019)
-
(The Southern African Institute of Mining and Metallurgy, 2015)Rising costs in the mining industry have necessitated a search for alternative methods for the recovery of metals from deposits that are no longer economically or environmentally exploitable by conventional mining. These ...
-
(Elsevier, 2017)Ultrasound has long been used as a non-destructive tool to test for the brittle fracture of materials. Could it be used as a similar tool to test for ductile failure? As a first step towards answering this question, we ...
-
(Elsevier Ltd, 2019)© 2018 Elsevier B.V. Bionanocomposite scaffolds based on aliphatic polyurethane (PU) and bioactive glass nanoparticles were produced by using a one-step in situ polymerization method. Bioactive glass nanoparticles (nBG) ...
-
(Elsevier, 2014)This paper presents a study of the in situ production of tantalum carbide nanodispersoids in a copper matrix. The copper matrix composites were produced by means of reactive milling in hexane (C6H14) followed by hot ...
-
(Elsevier, 2020)There is a growing interest in exploring the application of bioleaching for treating copper sulfide ores of decreasing grade and located at larger depth by in situ recovery (ISR) for its potential savings in ore extraction, ...
-
(SPRINGER/PLENUM PUBLISHERS, 2016)
-
(2012)The structural transformations induced by heating on MoO3 mesoporous samples grown in vapor-phase under helium and hydrogen were studied by in situ Raman spectroscopy. The samples were continuously irradiated by a HeeNe ...
-
(ROYAL SOC CHEMISTRY, 2016)This work reports the synthesis and characterization of palladium(u) complexes Pd(L-1)(2) (1), Pd(L-2)(2) (2), Pd(L-3)(2) (3) and Pd(L-4)(2) (4), where (LH)-H-1: 1-naphthaldehyde thiosemicarbazone; (LH)-H-2: 4-phenyl-(1- ...
-
(Institute of Physics Publishing, 2018)In the last years, pulsed reduced low dose radiation has been proposed as an alternative for treatment of recurrent cancer. Nonetheless, distinction between the effects of low dose pulsed and continuous radiation is barely ...
