(IOP Publishing Ltd, 2018)We report on the experimental realization of a quasi-one-dimensional photonic graphene ribbon supporting four flat-bands (FBs). We study the dynamics of fundamental and dipolar modes, which are analogous to the s and p ...
-
(Nature, 2018)Organic-inorganic hybrid halide perovskites compounds are emerging as new materials with great potential for efcient solar cells. This paper explores the possibility of increasing their photovoltaic efciency through ...
-
(Scientific Research Publishing, 2018)Diatom floras were examined in a high-altitude geothermal field, 4200 - 4500 m (29 degrees 19'S 68 degrees W'), located in the Central Andean dry Puna ecoregion or southern Altiplano. These locations include hostile ...

(Oxford University Press, 2018)High-elevation lakes in the tropics are subject to extreme environmental fluctuations and microbes may harbor a unique genomic repertoire, but their composition and diversity are largely unknown. Here, we compared the ...
-
(Elsevier, 2018)This paper presents the detailed description of a remarkable skull and partial postcranial skeleton of a very juvenile elasmosaurid referred to Tuarangisaurus keyesi (CD 427), from the upper Campanian-lower Maastrichtian ...
-
(Wiley, 2018)Aim: We assess biogeographical patterns, population structure and the range of species in the pulmonate genus Siphonaria across the sub-Antarctic. We hypothesized that locally endemic cryptic species will be found across ...
-
(Wiley, 2018)The genus Triptilion is endemic to central Chile, the Mendoza Province and western Patagonia in Argentina. It is currently composed of seven species: T. achilleae, T. benaventii, T. berteroi, T. capillatum, T. cordifolium, ...

(Elsevier, 2018)The study was carried out to determine Hg and Se concentrations in false killer whales stranded on the Estrecho de Magallanes, Chile, South America. Tissue samples of five mature specimens were analyzed (two females and ...
-
(Peking University Press, 2018)Chemical reactivity towards electron transfer is captured by the Fukui function. However, this is not well defined when the system or its ions have degenerate or pseudo-degenerate ground states. In such a case, the first-order ...
-
(Peking University Press, 2018)Quantitative correlation of several theoretical electrophilicity measures over different families of organic compounds are examined relative to the experimental values of Mayr et al. Notably, the ability to predict these ...
-
(Nature Publishing Group, 2018)Nanoparticles are ubiquitous in nature and are increasingly important for technology. They are subject to bombardment by ionizing radiation in a diverse range of environments. In particular, nanodiamonds represent a variety ...
-
(Nature Publishing Group, 2018)Schizophrenia is a neurodevelopmental disease characterized by cerebral connectivity impairment and loss of gray matter. It was described in adult schizophrenia patients (SZP) that concentration of VEGFA, a master angiogenic ...
-
(MDPI, 2018)Acidophile bacteria belonging to the Acidithiobacillus genus are pivotal players for the bioleaching of metallic values such as copper. Cell adherence to ores and biofilm formation, mediated by the production of extracellular ...
-
(MDPI, 2018)A series of hybrid heterostructured nanocomposites of ZnO with V2O5 nanotubes (VOx-NTs) in different mixing ratios were synthesized, with the aim of reducing the recombination of photoinduced charge carriers and to optimize ...
-
(Elsevier Science SA, 2018)This review focuses on the recent developments of unsymmetrically-substituted multidentate Schiff bases whose steric and electronic characteristics are easily manipulated by selecting suitable condensing aldehydes or ketones ...
-
(Elsevier, 2018)The transcription factor STAT3 has a crucial role in the development and maintenance of the nervous system. In this work, we treated astrocytes with oligomers of the amyloid beta peptide (A beta Os), which display potent ...
-
(Nature, 2018)We study the bulk and surface nonlinear modes of a modi ed one-dimensional discrete nonlinear Schrödinger (mDNLS) equation. A linear and a modulational stability analysis of the lowest- order modes is carried out. While ...
-
(Oxford University Press, 2018)While Chandrasekhar-mass (MCh) models with a low 56Ni yield can match the peak lumi- nosities of fast-declining, 91bg-like Type Ia supernovae (SNe Ia), they systematically fail to reproduce their faster light-curve evolution. ...

(Wiley, 2018)The Cactaceae is one of the most conspicuous and ecologically important plant families in the world. Its species may have specialist or generalist pollination systems that show geographic patterns, which are synthesised ...
