Where the ends meet: An overview of sex determination in Atheriniform fishes
(Karger, 2021-09)
Atheriniform fishes have recently emerged as attractive models for evolutionary, ecological, and molecular/physiological studies on sex determination. Many species in this group have marked temperature-dependent sex ...
Development of an impedimetric immunosensor to determine microcystin-LR: New approaches in the use of the electrochemical impedance spectroscopy was used in determining to determine kinetic parameters of immunoreactions
(Pergamon-Elsevier Science Ltd, 2020-09)
The development of new electrochemical immunosensors for the detection of environmental contaminants is of great interest due to their simplicity, high sensitivity, and extended analytical range. Because of the antibody ...
Linear solving for sign determination
(Elsevier Science, 2011-08)
We give a specific method to solve with quadratic complexity the linear systems arising in known algorithms to deal with the sign determination problem, both in the univariate and multivariate setting. In particular, this ...
The duplicated Y-specific amhy gene is conserved and linked to maleness in silversides of the genus Odontesthes
(Multidisciplinary Digital Publishing Institute AG, 2019-09-05)
Sex-determining genes have been successively isolated in several teleosts. In Odontesthes hatcheri and O. bonariensis, the amhy gene has been identified as a master sex-determining gene. However, whether this gene is ...
Elementary recursive quantifier elimination based on Thom encoding and sign determination
(Elsevier Science, 2017-08)
We describe a new quantifier elimination algorithm for real closed fields based onThom encoding and sign determination. The complexity of this algorithm is elemen-tary recursive and its proof of correctness is completely ...
Determination of cadmium in commercial tobacco by EMFAAS
(Royal Society of Chemistry, 2018-11)
In this work we present the use of EMFAAS (Electrothermal Metallic Furnace Atomic Absorption Spectroscopy) for the determination of Cd in the tobacco cigarettes of five commercial brands. Optimization of the experimental ...
Hybrid Treatments Based on Determinant Seniority Numbers and Spatial Excitation Levels in the Configuration Interaction Framework
(Elsevier Academic Press Inc, 2018-01)
In this work we project the Hamiltonian of an N-electron system onto a set of N-electron determinants cataloged by their seniority numbers and their excitation levels with respect to a reference determinant. We show that, ...
Supramolecular analytical chemistry: Spectrofluorimetric determination of 6-hydroxymelatonin with hydroxypropyl-β-cyclodextrin
(Arkat, 2011-05)
The effect of the addition of native (α, β and γ) and derivative (methyl-β and hydroxypropyl-β) cyclodextrins (CD) on the fluorescence of 6-hydroxymelatonin (6HM) in water solutions was studied. The fluorescence of the ...
The determinant of the distance matrix of graphs with blocks at most bicyclic
(Elsevier Science Inc., 2021-04-01)
Let G be a connected graph on n vertices and D(G) be its distance matrix. The formula for computing the determinant of this matrix in terms of the number of vertices is known when the graph is either a tree or a unicyclic ...
Determinants of unreported income in Latin American companies: a business perspective
(Inderscience, 2021-06)
This study aims to empirically identify factors associated with unreported income in Latin American registered firms. We use World Bank Enterprise Survey 2017 data from Argentina, Bolivia, Ecuador, Paraguay, Peru, and ...
