Structures of immature flavivirus particles [PDF]

The EMBO Journal, 2003
Structures of prM-containing dengue and yellow fever virus particles were determined to 16 and 25 A resolution, respectively, by cryoelectron microscopy and image reconstruction techniques. The closely similar structures show 60 icosahedrally organized trimeric spikes on the particle surface.

Analysis on the Difference of Impact Response between Single Coal-Rock Particle and the Box Structure-Based Tail Beam

Shock and Vibration, 2021
In the process of coal caving, the basis of identifying coal and rock by the vibration signal is the difference of the tail beam response when coal-rock impacts the tail beam, and the tail beam in the hydraulic support is a complex box structure with ...

Quantum Mechanics of a Point Particle in 2+1 Dimensional Gravity [PDF]

, 1997
We study the phase space structure and the quantization of a pointlike particle in 2+1 dimensional gravity. By adding boundary terms to the first order Einstein Hilbert action, and removing all redundant gauge degrees of freedom, we arrive at a reduced ...
