A Rapid Instrument Exchange System for Humanoid Robots in Minimally Invasive Surgery
Bingcong Zhang, Yihang Lyv, Lianbo Ma +6
Humanoid robot technologies have demonstrated immense potential for minimally invasive surgery (MIS). Unlike dedicated multi-arm surgical platforms, the inherent dual-arm configura…
The dwarf nova EX Draconis: a short review
Raymundo Baptista, Wagner Schlindwein
EX Draconis (EX Dra) is a long period dwarf nova showing ~2 mag outburst which lasts for ~7 d and recur on a timescale of (20-30) d. Its deep eclipses allows one to trace the chang…
The eclipsing novalike cataclysmic variable CRTS SSS100505 J093417-174421
R. Baptista, A. Bruch, R. Lopes de Oliveira +3
Time-resolved optical photometry, complemented by TESS data and long-term survey light curves, reveals that the transient object CRTS SSS100505 J093417-174421 is an eclipsing noval…
Modeling the high-brightness state of the recurrent nova T CrB as an enhanced mass-transfer event
Wagner Schlindwein, Raymundo Baptista, Gerardo Juan Manuel Luna
T~Coronae Borealis is the nearest symbiotic recurrent nova. Twice in the last two centuries, in 1866 and 1946, the accreted material ignited on the surface of the white dwarf via r…
Mass-transfer Outburts reborn: Modeling the light curve of the dwarf nova EX Draconis
Wagner Schlindwein, Raymundo Baptista
EX Draconis is an eclipsing dwarf nova that shows outbursts with moderate amplitude ( mag) and a recurrence timescale of -30 d. Dwarf novae outbursts are expla…
Cyclical period changes in cataclysmic variables: a statistical study
Leandro Souza, Raymundo Baptista
We report the results of a statistical study of cyclical period changes in cataclysmic variables (CVs). Assuming the third-body hypothesis as the cause of period changes, we estima…
