Experimental observation of a complex periodic window
(AMER PHYSICAL SOC, 2008)
The existence of a special periodic window in the two-dimensional parameter space of an experimental Chua's circuit is reported. One of the main reasons that makes such a window special is that the observation of one implies ...
Periodic window arising in the parameter space of an impact oscillator
(ELSEVIER SCIENCE BV, 2010)
In the bi-dimensional parameter space of an impact-pair system, shrimp-shaped periodic windows are embedded in chaotic regions. We show that a weak periodic forcing generates new periodic windows near the unperturbed one ...
Broken windows policing and crime: Evidence from 80 Colombian cities
(Universidad de los Andes, Facultad de Economía, CEDEFacultad de Economía, 2022-06)
We study the effects of broken windows policing on crime using geo-located crime and arrest reports for 80 Colombian cities. Broadly defined, broken windows policing consists of intensifying arrests -sometimes for minor ...

We study the effects of broken windows policing on crime using geo-located crime and arrest reports for 80 Colombian cities. Broadly defined, broken windows policing consists of intensifying arrests—sometimes for minor ...
To tip or not to tip: The Window of Tipping Point Analysis for social-ecological systems
(Wiley, 2022)
We introduce six steps to define a “Window of Tipping Point Analysis” which serves as a framework to increase the understanding of processes and tipping points in social-ecological systems. We apply the Window of Tipping ...
Effectiveness of Piezoelectric Surgery in Preparing the Lateral Window for Maxillary Sinus Augmentation in Patients with Sinus Anatomical Variations: A Case Series
(QUINTESSENCE PUBLISHING CO INCHANOVER PARK, 2013-08-02)
Purpose: The present article sought to evaluate the effectiveness of a piezoelectric surgical unit for maxillary sinus augmentation surgeries in avoiding perforation of the sinus membrane and other possible procedural ...
[Safe blood in the absence of viral infections due to HBV, HCV and HIV in serological window period in donors]
(2011)
OBJECTIVE: To determine the prevalence of viral infections (HBV, HCV and HIV) in serological window period in blood donors screened with nucleic acid testing (NAT). MATERIALS AND METHODS: We assessed all blood donors from ...
