Noble-gas implantation was used to introduce defects in n-type degenerate ScN thin films tailor their transport properties. The electrical resistivity increased significantly with the damage levels created, while electron mobility decreased regardless of nature ion implanted and doses. However, property characterizations showed that two types were formed during implantation, named point-like co...

Multiple RNA polymerase II (RNAPII) molecules can transcribe a gene simultaneously, but what happens when such polymerases collide--for example due to polymerase pausing or DNA damage? Here, RNAPII collision was characterized using a reconstituted system for simultaneous transcription by two polymerases. When progression of leading polymerase is obstructed, rear-end collision entails a transien...

Rear-end traffic collision has been a crucial problem due to numerous injury even death and corresponding economic and social damage. In order to eliminate these threats, a large number of researchers have paid effort on this area, with timeconsuming artificial intelligence-inspired methods or mathematical method in strict assumptions. In this paper, we propose a VANET-based real-time rear-end ...

Some of the next generation massive spectroscopic survey projects, plan to use thousands of fiber positioner robots packed at a focal plane to quickly move in parallel the fiber-ends from the previous to the next target points. The most direct trajectories are prone to collision that could damage the robots and impact the survey operation. We thus present here a motion planning method based on ...

This paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. Axial bearing analysis is done numerically using nonlinear finite element code LS-DYNA. In this analysis, changes of two main parameters including measure of energy absorp...

We consider the slot-synchronized collision channel without feedback, in which K active users all transmit their packets to one sink. It is assumed that the channel has the ability of the multiple-packet reception (MPR), i.e., can accommodate at most γ (1 ≤ γ < K) simultaneous transmissions. Each user accesses the channel following a specific periodical zero-one pattern, called the protocol seq...
