Offenders become the victim in virtual reality: impact of changing perspective in domestic violence
Autor: S. Seinfeld, J. Arroyo-Palacios, G. Iruretagoyena, R. Hortensius, L. E. Zapata, D. Borland, B. de Gelder, M. Slater, M. V. Sanchez-Vives
Publikováno v: Scientific Reports, Vol 8, Iss 1, Pp 1-11 (2018)
Abstract The role of empathy and perspective-taking in preventing aggressive behaviors has been highlighted in several theoretical models. In this study, we used immersive virtual reality to induce a full body ownership illusion that allows offenders

Autor: L. E. Zapata, M. Pergament, M. Schust, S. Reuter, J. Thesinga, C. Zapata, M. Kellert, U. Demirbas, A.-L. Calendron, Y. Liu, F. X. Kärtner
Publikováno v: Optics letters. 47(24)
We present results on the development of a cryogenic Yb:YAG multi-pass laser amplifier based on a composite thin-disk design and demonstrate one-joule, diffraction limited, chirped 234-ps pulses with 50% optical-to-optical efficiency. High beam quali

Effect of fly ash and nanosilica on compressive strength of concrete at early age
Autor: L. E. Zapata, N. M. García, Mauricio Cabrera-Ríos, Oscar Marcelo Suárez
Publikováno v: Advances in Applied Ceramics. 114:99-106
The replacement of cement by mineral admixtures in concrete has been of increasing interest in the construction industry. Nevertheless, several of the potential replacements, such as fly ash class F, lower the compressive strength of concrete at earl

Autor: L. E. Zapata Orduz, M. F. Mantilla Díaz, J. A. Villamizar Pabón, S. Ruiz Martínez
Publikováno v: Journal of Physics: Conference Series. 1386:012032
A study of the mechanical behavior of self-compacting concrete mixtures under sand replacement (as fine aggregate) by iron slag (residue from industrial machining) from 0.0% to 50.0% of mass, variations of water/cementitious material ratio between 0.

Rheological performance and compressive strength of superplasticized cementitious mixtures with micro/nano-SiO2 additions
Autor: Genock Portela, L. E. Zapata, Oscar Marcelo Suárez, O. Carrasquillo
Publikováno v: Construction and Building Materials. 41:708-716
This study aims to assess the effects of micro and nano-SiO 2 under various dosages of carboxylated-polyether-copolymer-type superplasticizer on the rheological properties of grouts in the fresh state. In the hardened state, compressive tests and sca

Solid state laser driver for Extreme Ultraviolet Lithography. Revision 1
Autor: P. Reichert, J. Honig, L. A. Hackel, L. E. Zapata
We describe the design and initial performance of a Nd:YAG laser master oscillator/phase conjugated power amplifier as a driver for extreme ultraviolet lithography. The design provides 0.5 to 1 joule per pulse with about 5 ns pulse width and excellen
