    Preliminary results of simulated vortex encounters by a twin-engine, commercial aircraft during final landing approach

    Get PDF
    Piloted simulations of encounters with vortices of various ages and degrees of attenuation were performed with the Visual Motion Simulator. In the simulations, a twin engine, commercial transport on final approach, encountered the modeled vortices of a four engine, wide body, commercial transport. The data show the effect of vortex age and attenuation on the severity of the initial upset, as well as the effect of the vortex encounters on the landing capability

    Interacting electrons on a quantum ring: exact and variational approach

    Full text link
    We study a system of interacting electrons on a one-dimensional quantum ring using exact diagonalization and the variational quantum Monte Carlo method. We examine the accuracy of the Slater-Jastrow -type many-body wave function and compare energies and pair distribution functions obtained from the two approaches. Our results show that this wave function captures most correlation effects. We then study the smooth transition to a regime where the electrons localize in the rotating frame, which for the ultrathin quantum ring system happens at quite high electron density.Comment: 19 pages, 10 figures.

    Nondeterministic self-assembly with asymmetric interactions.

    Get PDF
    We investigate general properties of nondeterministic self-assembly with asymmetric interactions, using a computational model and DNA tile assembly experiments. By contrasting symmetric and asymmetric interactions we show that the latter can lead to self-limiting cluster growth. Furthermore, by adjusting the relative abundance of self-assembly particles in a two-particle mixture, we are able to tune the final sizes of these clusters. We show that this is a fundamental property of asymmetric interactions, which has potential applications in bioengineering, and provides insights into the study of diseases caused by protein aggregation.Winton Programme for the Physics of Sustainability, Gates Cambridge, Oppenheimer PhD studentship, NanoDTC Cambridge (Grant ID: EP/L015978/1), Engineering and Physical Sciences Research Council (Grant ID: EP/L504920/1), Royal SocietyThis is the author accepted manuscript.
