BACKGROUND Little is known about the characteristics of people who die by jumping from different locations (e.g. bridges, buildings) and the factors that might influence the effectiveness of suicide prevention measures at such sites. METHODS We collected data on suicides by jumping (n = 134) between 1994 and 2003 in Bristol, UK, an area that includes the Clifton Suspension Bridge, a site reno...

Using Brownian dynamics simulations, we systematically study the effective interaction between two parallel hard walls in a 2D suspension of self-propelled (active) colloidal hard spheres, and we find that the effective force between two hard walls can be tuned from a long range repulsion into a long range attraction by changing the density of active particles. At relatively high densities, the...

We discuss the long-time dynamical behavior of the non-autonomous suspension bridge-type equation, where the nonlinearity g(u, t) is translation compact and the time-dependent external forces h(x, t) only satisfy Condition (C∗) instead of being translation compact. By applying some new results and the energy estimate technique, the existence of uniform attractors is obtained. The result improve...

ingly collapsed, pulseless at both wrists, face pale and anxious, lips livid. She could, however, be roused to give her name, and attempted to sit up, but sank back and nearly fainted. On being placed in bed, complained of pain in the chest, and of the extreme coldness of her limbs. Hot bottles and blankets were applied, and brandy swallowed without difficulty. The condition of collapse, with w...

This work is focused on the doubly nonlinear equation ∂ttu ∂xxxxu p − ‖∂xu‖L2 0,1 ∂xxu ∂tu k2u f , whose solutions represent the bending motion of an extensible, elastic bridge suspended by continuously distributed cables which are flexible and elastic with stiffness k2. When the ends are pinned, long-term dynamics is scrutinized for arbitrary values of axial load p and stiffness k2. For a gene...

The long-span multi-tower suspension bridge is widely used in the construction of river and sea crossing bridges. load-bearing safety anti-sliding its main cable are directly related to structural a bridge. Failure mechanisms discussed. Meanwhile, tribo-corrosion-fatigue cable, contact, slip behaviors saddle service assessment reviewed. Finally, research trends proposed. It great significance i...
