(AMER GEOPHYSICAL UNION, 2010-09-30)The key objective of this paper is to develop a 1‐D hydrodynamic and sediment transport model, namely, RILL1D, that handles transcritical flows over abrupt changes (e.g., formation of pool crests and width change) in a ...
-
(American Association for the Advancement of Science, 2000)Fossil rodent middens and wetland deposits from the central Atacama Desert (22°to 24°S) indicate increasing summer precipitation, grass cover, and groundwater levels from 16.2 to 10.5 calendar kiloyears before present (ky ...
-
(Institute of Electrical and Electronics Engineers, 2019)The development of new methods for biometrics using the 3-D surface of the iris could be useful in various applications, such as reliable identity verification of people, when only segments of the iris are available, the ...
-
(World Scientific Publ Co Pte Ltd, 2018)Since the International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems published its first issue in 1993, it has made important contributions to the research field of computer science. In this study, based ...
-
(Elsevier, 2019)This paper presents a study of the most cited papers, the most productive and influential institutions and countries, and the most influential authors in the tourism, leisure, and hospitality fields. The number of publications ...
-
(Taylor and Francis Inc., 2013)Calcium and voltage-activated potassium (BK) channels are key actors in cell physiology, both in neuronal and non-neuronal cells and tissues. Through negative feedback between intracellular Ca2+ and membrane voltage, BK ...
-
(Academic Press Inc., 1996)Ion channels are deeply involved in sperm physiology. In sea urchin sperm cyclic nucleotide levels increase during quimotaxis and in the acrosome reaction (AR). Although cyclic nucleotides are second messengers known to ...
-
(2007)We describe the operation of a midbrain neural circuit in pigeons that may participate in selecting and attending to one visual stimulus from the myriad displayed in their visual environment. This mechanism is based on a ...
-
(1995)In olfactory neurons from Caudiverbera caudiverbera, a mixture of putrid odorants trigger an inhibitory, K+-selective current and a hyperpolarizing receptor potential. The current-voltage relation resembles that of a ...
-
(Pensoft, 2020)Functional traits that predict plant invasiveness are a central issue in invasion ecology. However, in many cases they are difficult to determine, especially for a large set of species. Climatic niche traits can overcome ...
-
(BIOMED Central Ltd., 2017)Background: CLCA is a family of metalloproteases that regulate Ca2+-activated Cl- fluxes in epithelial tissues. In HEK293 cells, CLCA1 promotes membrane expression of an endogenous Anoctamin 1 (ANO1, also termed ...
-
(2009)One method to determine past climate has been the use of leaf morphological characteristics of fossil leaves quantifi ed using modern climate and canopy leaf characteristics. Fossil assemblages are composed of abscised ...
-
(Nature Publishing Group, 2019)Determining the clinical significance of germline and somatic KMT2D missense variants (MVs) in Kabuki syndrome (KS) and cancers can be challenging. We analysed 1920 distinct KMT2D MVs that included 1535 germline MVs in ...
-
(2007)The electrophilicity index, omega, of a series of substituted ethylenes used in some relevant organic reactions has been evaluated from the ionization potential JP) and the electron affinity (EA) computed by vertical ...
-
(Elsevier, 2015)© 2015 Elsevier B.V.The inter- and intramolecular aurophilic [ClAuPH3]2, [S(AuPH3)2] and [AuPH3]42+ interactions were studied using ab initio post-Hartree-Fock and DFT methodologies. The post-Hartree-Fock methods provide ...
-
(2003)The aim of this work is to find a method suitable at least for obtaining the isolated molecule band structure approximated by a Gaussian broadening of the discrete eigenvalues, to apply it for a first scan of bigger and ...
-
(2004)Southerly wind pulses are repeatedly observed in connection with upwelling off Point Curaumilla (33°S), around 20km south of Valparaíso. The remote forcing of coastal upwelling associated with intraseasonal coastal-trapped ...
-
(AMER CHEMICAL SOC, 2011-05-05)Bond order indexes are useful measures that connect quantum mechanical results with chemical understanding. One of these measures, the natural bond order index, based on the natural resonance theory procedure and part of ...
-
(Blackwell Publishing Ltd, 2015)© 2015 John Wiley & Sons Ltd/CNRS.The strength of species interactions influences strongly the structure and dynamics of ecological systems. Thus, quantifying such strength is crucial to understand how species interactions ...
-
(Elsevier Ltd, 2018)© 2018 Elsevier Ltd We present a high-resolution precisely dated terrestrial paleovegetation/paleoclimate record from Lago Pichilaguna, northwestern Patagonia (40°–44°S), which spans continuously from the Last Glacial ...
