ISS: Columbus.
In 2001, a total of 13 assembly and logistic flights to the ISS were made, using both Russian launchers and the Space Shuttle, including flights of the first European astronauts, payloads and Multi-Purpose Logistics Modules (MPLMs). Several US, Russian and Canadian elements have already been assembled in orbit and the fourth Expedition Crew is currently onboard. The cornerstone of ESA's contrib...
متن کاملComparative genomic analyses in Asparagus.
Garden asparagus (Asparagus officinalis L.) belongs to the monocot family Asparagaceae in the order Asparagales. Onion (Allium cepa L.) and Asparagus officinalis are 2 of the most economically important plants of the core Asparagales, a well supported monophyletic group within the Asparagales. Coding regions in onion have lower GC contents than the grasses. We compared the GC content of 3374 un...
متن کاملRemarks on ISS and Integral-ISS Stabilization with Positive Controls
We consider nonlinear systems with both control and disturbance inputs. The main problem addressed is the design of state feedback control laws, achieving ISS and integralISS disturbance attenuation, with restricted control under the assumption that an appropriate control Lyapunov function is known. Our results generalize the previous results on ISS and integral-ISS stabilization to the restric...
متن کاملISS and integral-ISS disturbance attenuation with bounded controls
We consider the problem of achieving disturbance attenuation in the ES and integral-ES sense for nonlinear systems with bounded controls. For the ISS case we derive a “universal” formula which ext,ends an earlier result of Lin and Sontag to systems with disturbances. For the integral-ISS case we give two constructions, one resulting in a smooth control law and the other in a switching control l...
متن کاملPolytomies in Comparative Analyses of Continuous Characters
Felsenstein's (1985) method of phylogenetically independent contrasts was the first statistically valid parametric method for correlation and regression analysis of continuous variables measured on multiple species. One requirement of the method is that the true phylogeny linking the species in the data set be known in full, including the lengths of the branches in units of expected variance of...
