Characterization of number fields by their integral trace form
(2018-11)
We prove that the integral trace form is a complete invariant for totally real number fields of fundamental discriminant. We also study the relations of this invariant with the trace-zero form and the shape of a number ...
Backward Blow-up Estimates and Initial Trace for a Parabolic System of Reaction-Diffusion
(ADVANCED NONLINEAR STUDIES, INC, 2010)
In this article we study the positive solutions of the parabolic semilinear system of competitive type
Proteomic analysis of liver from finishing beef cattle supplemented with a rumen-protected b-vitamin blend and hydroxy trace minerals
(2021-07-01)
Vitamin B and trace minerals are crucial molecular signals involved in many biological pathways; however, their bioavailability is compromised in high-producing ruminant animals. So far, studies have mainly focused on the ...
Seasonal and spatial variation of trace elements in sediments of three chilean basins
(Sociedad Chilena de Química, 2020)
Total concentrations of trace elements can provide fundamental information on the sediment contamination levels of the pollution indexes and the quality guidelines for sediment risk assessment. However, this information ...
Trace forms of certain subfields of cyclotomic fields and applications
(2020-05-07)
In this work, we present a explicit trace forms for maximal real subfields of cyclotomic fields as tools for constructing algebraic lattices in Euclidean space with optimal center density. We also obtain a closed formula ...
Higher composition laws, integral trace forms and an alternative proof for the Scholz reflection principle
(UniandesMaestría en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2018)
A classification of cubic fields can be done using the trace form and higher analogues of Gauss composition. Using these ideas a new proof for the Scholz reflection principle is given.
Paleoenvironments and ichnotaxonomy of insect trace fossils in continental mudflat deposits of the Miocene Calatayud–Daroca Basin, Zaragoza, Spain
(Elsevier Science, 2014-11)
The Miocene continental deposits in the Orera area, Calatayud–Daroca Basin, are composed of red and brown mudstones deposited in the dry mudflat, sepiolite and dolomicrites deposited in periodically desiccated alkaline ...
