The efficacy of visual Simultaneous Localization and Mapping (SLAM) diminishes in large-scale environments due to challenges in identifying distant landmarks, leading to a limited perception range and trajectory drift.This paper presents a practical method to Nature Book enhance the accuracy of feature-based real-time visual SLAM for compact unmann
Abstract Background A safe and effective vaginal microbicide could substantially reduce HIV acquisition for women.Consistent gel use is, however, of great importance to ensure continued protection against HIV infection, even with a safe and effective microbicide.We assessed the long-term correlates of consistent gel use in the MDP 301 clinical tria
Abstract Background In crosses between the proline-deficient mutant homozygous for p5cs1 and heterozygous for p5cs2 (p5cs1 p5cs2/P5CS2), used as male, and different Arabidopsis mutants, used as females, the p5cs2 mutant allele was rarely transmitted to the outcrossed progeny, suggesting that the fertility of the male gametophyte carrying mutations
In the automotive industry, the flow of air generates high resistance in the advance of vehicles.In light of this situation, the objective of the present invention is to take advantage of the force of the air itself to help propel vehicles and thus reduce fuel consumption.A channeling system has been designed based on a deflector that collects the
