The bacterial, eukaryotic, and T4 bacteriophage proSummary cessivity factors are all structurally similar, even though they do not share significant sequence similarity (Kong The crystal structure of the d9 subunit of the clampet al., 1992; Krishna et al., 1994; I.

To study the adaptation of current automobile design load highway bridges in China case separation passenger cars and trucks, a statistical method is proposed this paper to data special lanes for trucks. Four typical truck-based were selected as object, from which information continuous truck fleet was truck-specific lane flow samples, technical parameters vehicles determined. Finally, introduc...

Considering the slow response and unstable velocity of agricultural machinery caused by soil resistance, actuator delay, environmental change, fluctuation, other internal external factors under real working conditions, a kind following control system that considers variable load delay was proposed. Taking distance-keeping, velocity-following, acceleration-following as parameters, controller mod...

The Truck Factor designates the minimal number of developers that have to be hit by a truck (or quit) before a project is incapacitated. It can be seen as a measurement of the concentration of information in individual team members. We calculate the Truck Factor for 133 popular GitHub applications, in six languages. Results show that most systems have a small truck factor (46% have Truck Factor...

The chi (chi) and psi (psi) subunits of Escherichia coli DNA polymerase III form a heterodimer that is associated with the ATP-dependent clamp-loader machinery. In E. coli, the chi:psi heterodimer serves as a bridge between the clamp-loader complex and the single-stranded DNA-binding protein. We determined the crystal structure of the chi:psi heterodimer at 2.1 A resolution. Although neither ch...

Automation in underground mining enhances safety and leads to economic efficiencies. After more than 50 years of research, automation tasks have gradually been growing out of the classic engineering/mechanical environment and require a sophisticated datamining treatment. The success of (mechanical) process automation has left only one remaining place in the coal-excavation process where human l...

OBJECTIVE This study presents data from a large-scale anthropometric study of U.S. truck drivers and the multivariate anthropometric models developed for the design of next-generation truck cabs. BACKGROUND Up-to-date anthropometric information of the U.S. truck driver population is needed for the design of safe and ergonomically efficient truck cabs. METHOD We collected 35 anthropometric d...
