We show that at the energies and luminosities soon to be attained with antiproton—proton colliding beams, the cross section for antiquark—quark annihilation, leading to production of a gluon jet in association with a Z 0 at large angles, is measurable and has a magnitude, energy dependence,...
“In PBS proton therapy, each layer is delivered in a series of discrete pencil beam spots. The scanning magnets are used to reconfigure the system to deliver dose in the subsequent position,” explains Lee. “This is not an instantaneous process. In the presence of tumour motion due to res...
I don't know of even one sci-fi film or TV series that demonstrates the proper functioning of the laser beam. Most make the beams visible through special effects because it would be unsatisfying for the viewer to see a character fire a laser and not see anything. Sound in Space When the...
A critical value which must be known is the anode’s heat storage capacity. The tungsten/copper anode has a limited thermal conductance, thereby limiting its ability to dissipate the great heat generated by the focused electron beam. To cope with this Coolidge tubes often are run at a duty c...
second primary malignancies), and in adults to provide an effective dose to tumours that are localised adjacent to structures sensitive to the effects of radiation, such as the brainstem and spinal cord.88,89One potential limitation of PBT is that the range of a proton is subject to ...

In this section, we will thus derive the general form of the transition probability generated by top-hat functions. –8– ρ(µ2) ∆m221 ∆m232 0 m21 m22 m23 µ2 b1 b2 b3 Figure 3. Sketch of the form of the top-hat ρs(µ2) for 3 flavour oscillations as defined in ...
Modulation of sea surface temperature (SST) patterns by interactions between seasonal and interannual variabilities in the Indian Ocean (IO) region are studied via a hierarchy of experiments utilizing both a 4-1/2 layer ocean model in a realistic tropical Indian Ocean basin, and a version of ...
How these artificial gravity fields are generated are unknown (remember, sci-fi writers are free to extrapolate). Currently, the only known means of producing artificial gravity is spinning the astronauts in a wheel-like environment. Centripetal acceleration towards the center of the wheel produces ...
