Discontinuous continuity: Structural change and its (divergent) meanings in Latin American structuralism and neo-structuralism
(Universidad Nacional de Colombia, 2020-06)
This paper analyses the continuities and discontinuities regarding the concept of structural change in Latin American structuralism and neo-structuralism and considers the global context in which these ideas and their ...
The effectiveness of the gyroscopic effect for controlling structural vibrations
(Taylor & Francis Ltd, 2021-07)
It is well known that seismic and wind induced vibration is an important issue in structural performance. To mitigate the problem of structural vibrations, many methodologies have been proposed and implemented. In this ...
Vaisman solvmanifolds and relations with other geometric structures
(International Press Boston, 2020-02)
We characterize unimodular solvable Lie algebras with Vaisman structures in terms of Kahler flat Lie algebras equipped with a suitable derivation. Using this characterization we obtain algebraic restrictions for the existence ...
Generalized complex and paracomplex structures on product manifolds
(Real Acad Ciencias Exactas Fisicas & Naturales, 2020-07-13)
On a product manifold (M, r), we consider four geometric structures compatible with r, e.g. hyper-paracomplex or bi-Lagrangian, and define distinguished generalized complex or paracomplex structures on M, which interpolate ...
BeEP Server: using evolutionary information for quality assessment of protein structure models
(Oxford University Press, 2013-07)
The BeEP Server (http://www.embnet.qb.fcen.uba.ar/embnet/beep.php) is an online resource aimed to help in the endgame of protein structure prediction. It is able to rank submitted structural models of a protein through an ...
Platy structure development under no-tillage in the northern humid Pampas of Argentina and its impact on runoff
(2017)
The no-tillage system (NT) is widespread in the silty soils of the Argentine Humid Pampas. The aims of this study were i) to characterize the evolution of the structure of the A horizon in the northern Humid Pampas due to ...
Modified Genetic Algorithm to Model Crystal Structures: III. Determination of Crystal Structures Allowing Simultaneous Molecular Geometry Relaxation
(John Wiley & Sons Inc, 2004-12)
The modified genetic algorithm (MGAC) has been extended to allow simultaneous relaxation of molecular geometry during optimization of the crystalline structure. The method was applied to L-alanine and DL-alanine for two ...
Experimental and ab initio study of the structural and optical properties of ZnO coatings: Performance of the DFT+U approach
(University of Novi Sad, 2020-12)
In this work, ZnO coatings were produced by the spray-pyrolysis technique and characterized by scanning electron microscopy, X-ray diffraction and optical transmittance spectroscopy. The experimental results were compared ...
Le Corbusier and a New Structural System as the Germ of the Modern Grammar
(David Publisher, 2017)
The opposition between the terms carcasse (carcass), conceptualized by Auguste Perret, and ossature (frame), proposed as an alternative by Le Corbusier, gives rise to the exploration of the capital contribution of the ...
Predicting 13Ca chemical shifts for validation of protein structures
(Springer, 2007-07)
The 13Ca chemical shifts for 16,299 residues from 213 conformations of four proteins (experimentally determined by X-ray crystallography and Nuclear Magnetic Resonance methods) were computed by using a combination of ...
