The miniF plasmid C protein: sequence, purification and DNA binding

open access: yesNucleic Acids Research, 1986
The C (pifC) protein of miniF represses transcription of its own gene by binding to the pif operator (pifO); it is also needed for replication initiated from the miniF primary origin (ori-1). We have determined the nucleotide sequence of the C gene. The gene has been inserted into an expression vector under Ptrp control where it is expressed at high ...

The Research and Optimization of Parallel Finite Element Algorithm based on MiniFE

open access: yesCoRR, 2015
Finite element method (FEM) is one of the most important numerical methods in modern engineering design and analysis. Since traditional serial FEM is difficult to solve large FE problems efficiently and accurately, high-performance parallel FEM has become one of the essential way to solve practical engineering problems.

Effects of magnification and visual accommodation on aimpoint estimation in simulated landings with real and virtual image displays [PDF]

open access: yes
Twenty professional pilots observed a computer-generated airport scene during simulated autopilot-coupled night landing approaches and at two points (20 sec and 10 sec before touchdown) judged whether the airplane would undershoot or overshoot the ...

Real-time 3-D X-ray and gamma-ray viewer [PDF]

open access: yes, 1983
A multi-pinhole aperture lead screen forms an equal plurality of invisible mini-images having dissimilar perspectives of an X-ray and gamma-ray emitting object (ABC) onto a near-earth phosphor layer. This layer provides visible light mini-images directly

Haptic-GeoZui3D: Exploring the Use of Haptics in AUV Path Planning [PDF]

open access: yes, 2003
We have developed a desktop virtual reality system that we call Haptic-GeoZui3D, which brings together 3D user interaction and visualization to provide a compelling environment for AUV path planning.

The effects of viewpoint on the virtual space of pictures [PDF]

open access: yes
Pictorial displays whose primary purpose is to convey accurate information about the 3-D spatial layout of an environment are discussed. How and how well, pictures can convey such information is discussed.

Another Generalized Transmuted Family of Distributions: Properties and Applications [PDF]

open access: yes, 2016
We introduce and study general mathematical properties of a new generator of continuous distributions with two extra parameters called the Another generalized transmuted family of distributions. We present some special models.
