A recent Letter [1] presents an experiment of ghost imaging with chaotic light. We definitely disagree with two main claims of the accompanying theory. The first one is ‘‘the explanation in terms of statistical correlation of intensity fluctuations would not give an acceptable interpretation for this experiment.’’ In the experiment of [1] (analogous to the ghost image experiment of [2]), a beam...

A beam of light passing near the centre of the pupil of a human eye stimulates the retina more than an identical beam making an entry from the edges of the pupil. This is Stiles-Crawford effect of the first kind (SCE I). This diminution in the effective brightness of a beam is retinal in origin. But in the computation of how the human eye responds to different spatial frequencies in the object,...

The industrial electron accelerator named FANTRON-I whose merits are its low fabrication cost, high reliability and easy maintainability is under development at Physico technology laboratory, KAPRA (Korea Accelerator and Plasma Research Association). To make the simplified machine, it is required to optimise the beam energy gain and beam transport efficiency. The beam energy gain is dependent o...

Cryocooled insulin and thaumatin crystals were irradiated in a series of alternating data collections and high-dose-rate exposures using either a vertically focused or vertically defocused beam. The main result is that the radiation damage is limited to the exposed region, which can be explained by the short range of the photoelectrons and the Auger electron cascade produced by light elements. ...

Polarimeters are necessary tools for measuring and maintaining the beam polarization during the acceleration process. They serve, as well, as a yardstick for performing spin physics experiments. In this paper, I will describe the principles of measuring proton beam polarization and the techniques that are employed at various energies. I will use as a guide the design work for the Polarized Prot...

In this paper, we first introduce a generalized version of open shop scheduling (OSS), called generalized cyclic open shop scheduling (GCOSS) and then develop a hybrid method of metaheuristic to solve this problem. Open shop scheduling is concerned with processing n jobs on m machines, where each job has exactly m operations and operation i of each job has to be processed on machine i . However...
