From hereditary "caciques" to "alcaldes" and elected "mandones". Legitimacy of the local power in the Indian "pueblos" constituted with an ethnic base, in the valley of the Cauca river (1675-1800) 

Arenas, Héctor Cuevas (Universidad Nacional de Colombia, 2017-01-28)
The author analyzes the change of heritage to the election and the local consensus -as legitimizing elements of the access to the local power-in the pueblos of indians of the the valley of Cauca river during the second ...

CHY loop integrands from holomorphic forms 

Gomez, Humberto; Mizer, Sebastian; Zhang, Guojun (Springer Verlag, 2017-03-01)
Recently, the Cachazo-He-Yuan (CHY) approach for calculating scattering amplitudes has been extended beyond tree level. In this paper, we introduce a way of constructing CHY integrands for Φ3 theory up to two loops from ...

Constraints on lepton number violating short-range interactions from |ΔL| = 2 processes 

Quintero, Néstor (Elsevier B.V., 2017-01-10)
In this work we study the short-range contributions that induce effective lepton number violating (LNV) interactions. We obtain a full set of constraints on the effective short-range couplings from a large variety of ...

Search of allosteric inhibitors and associated proteins of an AKT-like kinase from trypanosoma cruzi 

Ochoa, Rodrigo; Rocha-Roa, Cristian; Marín-Villa, Marcel; Robledo, Sara María; Varela-M, R. E. (MDPI AG, 2018-12-12)
Proteins associated to the PI3K/AKT/mTOR signaling pathway are widely used targets for cancer treatment, and in recent years they have also been evaluated as putative targets in trypanosomatids parasites, such as Trypanosoma ...

A preliminary study of cyclic voltammetry in glassy carbon electrode. Redox Behaviour of 2-Amino-4-phenylthiazoles 

Morales-Morales, Jimmy Alexander; Rios-Acevedo, J. J.; Florez-López, E. (Institute of Physics Publishing, 2018-12-10)
In this work a voltammetric study of the reduction processes of five substituted 2-Amino-4-(4-X-phenyl) thiazoles (-X =-H,-OCH 3 ,-CH 3 ,-Cl,-NO 2 ) in dimethylsulphoxido was performed. In the potential range considered ...

Electrochemical reduction processes on glassy carbon electrode of 2-Amino-4-phenylthiazoles. 

Morales-Morales, Jimmy Alexander; Salazar-Osorio, M.; Florez-López, E. (Institute of Physics Publishing, 2018-12-18)
In this work the electrochemical reduction of the compounds 2-Amino-4-(4-R-phenyl)thiazoles (1a, R =-H and 1b, R =-NHCOCH 3 ) was performed by cyclic voltammetry in dimethylsulfoxide (DMSO) + 0,1 M tetraethylammonium ...

Study of the electrochemical oxidation of 2-Thiazolamine and 2-Oxazolamine on a platinum wire as working electrode 

Morales-Morales, Jimmy Alexander; Villamarin, A. F.; Florez-López, E.; Rios-Acevedo, J. J. (Institute of Physics Publishing, 2018-12-10)
The electrochemical oxidation of 2-aminothiazole (2AT) and 2-aminooxazole (2AO) was studied by means of the cyclic voltammetry technique (VC), on a Pt wire as working electrode. An anodic wide peak centred at 0.79V was ...

The use of high-resolution historical images to analyse the Leopard pattern in the arid area of La Alta Guajira, Colombia 

Fuentes, José; Varga, Diego; Pintó, Josep (MDPI AG, 2018-10-10)
A recent review of global arid areas supports the idea that there are two patterns to vegetation in arid lands. Patches of thick vegetation alternate with those with much less vegetation or none at all. There is a specific ...

Future perspectives for a weak mixing angle measurement in coherent elastic neutrino nucleus scattering experiments 

Cañas, Blanca C.; Garcés, Estela A.; Miranda, Omar G.; Parada, Alexander (Elsevier B.V., 2018-09-10)
After the first measurement of the coherent elastic neutrino nucleus scattering (CENNS) by the COHERENT Collaboration, it is expected that new experiments will confirm the observation. Such measurements will allow to put ...

Search for lepton-number-violating signals in the charm sector 

Milanés, Diego A.; Quintero, Néstor (American Physical Society, 2018-11-01)
We explore signals of lepton-number-violation in the charm physics sector. We study the four-body |ΔL|=2 decays of the D0 meson, D0→P-π-μ+μ+ (P=π, K) as an alternative evidence of the Majorana nature of neutrinos. We carry ...
