Microstrip 3-Bit Fractal-based Phase Shifter
Autor: L. P. Pontes, E. M. F. de Oliveira, C. P. N. Silva, A. G. Barboza, M. T. de Melo, Ignacio Llamas-Garro
Publikováno v: Journal of Microwaves, Optoelectronics and Electromagnetic Applications, Vol 21, Iss 4, Pp 598-604 (2022)
Abstract This paper presents the implementation of a 3-bit microstrip fractal-based phase shifter operating in the 430 MHz to 470 MHz frequency range. The fractal structure is used to confine different delay line lengths in the same area due to the s

Snake Venom Disintegrins and Cell Migration
Autor: Heloisa S. Selistre-de-Araujo, Carmen L. S. Pontes, Cyntia F. Montenegro, Ana Carolina B. M. Martin
Publikováno v: Toxins, Vol 2, Iss 11, Pp 2606-2621 (2010)
Cell migration is a key process for the defense of pluricellular organisms against pathogens, and it involves a set of surface receptors acting in an ordered fashion to contribute directionality to the movement. Among these receptors are the integrin
