(Wiley, 2020)To increase efficiencies of bifacial solar cells, emitter, back surface field (BSF), and metal patterns must be optimized. We study the influence of paste volume, through multiple prints, of two silver pastes on the contact ...
-
(Springer, 2020)For a C-2-smooth function on a finite-dimensional space, a necessary condition for its quasiconvexity is the positive semidefiniteness of its Hessian matrix on the subspace orthogonal to its gradient, whereas a sufficient ...
-
(Springer, 2020)One of cadmium's major exposure routes to humans is through rice consumption. The concentrations of cadmium in the global polished (white), market rice supply-chain were assessed in 2270 samples, purchased from retailers ...
-
(Taylor & Francis, 2020)The understanding of closed-shell interactions has become of tremendous relevance in the ever-growing field of supramolecular chemistry. Here, we present a theoretical study in which we characterised the intermolecular ...
-
(FDI World Dental, 2020)Objective: Laprise et al. (2019) observed a positive association between oral sex practices and oropharyngeal cancers (OPC) among HPV-negative individuals. Because oral HPV infections are likely to be transmitted through ...
-
(Servicio Nacional Geología Minerva, 2020)The seabed included in the Chilean Exclusive Economic Zone (EEZ) has proper conditions to originate and host different ore deposits, but its geological knowledge is scarce and scattered. The existent studies are very limited ...
-
(Revista Biota Neotropica, 2020)Populations that breed along steep elevation gradients show diverse physiological and morphological changes in response to the different environmental conditions. The latter has been discussed by Bergmann's and Allen's ...
-
(Soc Romana Ultrasonografe Medicina Biologie-Srumb, 2020)Aims: To provide information on the current evidence regarding the diagnostic performance of ultrasound and MRI for assessing parametrial involvemmt in cervical cancer using the histological report as the reference standard, ...
-
(Amer Physical Soc, 2020)We measured the effective diffusion coefficient in regions of microfluidic networks of controlled geometry using the fluorescence recovery after photobleaching (FRAP) technique. The geometry of the networks was based on ...
-
(Nature, 2020)Studies of host-parasite relationships largely benefit from adopting a multifactorial approach, including the complexity of multi-host systems and habitat features in their analyses. Some host species concentrate most ...
-
(Elsevier, 2020)Background: Central venous cannulation (CVC) is common and necessary in pediatric intensive care. However, this procedure is not without risks or complications. Although CVCs have classically been placed following anatomical ...
-
(Wiley, 2020)Mesenchymal stem cells (MSCs) have fueled ample translation for the treatment of immune-mediated diseases. They exert immunoregulatory and tissue-restoring effects. MSC-mediated transfer of mitochondria (MitoT) has been ...
-
(IOP, 2020)We deform, in pure shear, a thin sample of Cu50Zr50 metallic glass using a molecular dynamics simulation up to, and including, failure. The experiment is repeated ten times in order to have average values and standard ...
-
(Elsevier, 2020)We address the perfect transmission of a plane acoustic wave at oblique incidence on a perforated, sound penetrable or rigid, film in two-dimensions. It is shown that the Brewster incidence theta* realizing so-called ...
-
(Universidad Complutense de Madrid, 2020)In Mapudungun, evidentiality is expressed by two elements: the reportative marker piam and the morpheme -rke. The latter has three meanings: inferential, reportative and mirative. Thus, reportativity can be expressed by ...
-
(Springer, 2020)Grade control and short-term planning determine the performance of a mining project. Improving this decision, by collecting the most informative samples (data) may have significant financial impact on the project. In this ...
-
(Springer, 2020)Achieving successful outplanting of trees on increasingly harsher sites is a global concern. In Chile, for example, new Eucalyptus globulus plantations are being targeted to poorer, low fertility sites where additional ...
-
(Routledge, Taylor & Francis, 2020)This study was conducted to explore the neuropsychological abilities of premature Chilean children. Two groups (Premature and Control, 10 children each, age ranging from 5 to 7.11) were established based on weeks of gestation ...
-
(Springer, 2020)Given a simple graph G, a set C subset of V(G)\documentclass[12pt] is a neighborhood cover set if every edge and vertex of G belongs to some G[v] with v is an element of C\documentclass[12pt] denotes the subgraph of G ...
-
(Taylor & Francis, 2020)Chemical thinning of apple (Malus domestica Borkh.) has been practised for 50 years but it remains an unpredictable part of apple production with large variations from year to year and within years. Carbohydrate availability ...
