Optical gratings are used extensively for beamsteering in the visible and IR range of the spectrum. Change in the dielectric permittivity of a semiconductor medium resulting from the excitation of a nonequilibrium electron-hole plasma makes it possible to extend this technique to MMW frequencies. A photo-induced plasma grating (PIPG) can be easily rewritten by changing the illumination pattern,...

A computer code has been developed to follow the processes of electronpositron pair production, annihilation, bremsstrahlung and Comptonization in a slab of mildly relativistic thermal plasma. The resulting equilibrium solutions are compared with the semi-analytic calculations of Svensson[1] .

We describe the resolution of the plasma apolipoproteins with molecular weights from 8,800 to greater than 550,000, using a 3.5% sodium dodecyl sulfate-glycerol polyacrylamide slab gel system. The simplicity of this system and the resolution of proteins over a broad range of molecular weights will make it particularly useful in investigations of apolipoprotein composition of plasma lipoproteins.

Aims. Analytical theory predicts the existence of trapped global (or fundamental) sausage fast magnetoacoustic modes in thick and dense coronal loops only, with the periods estimated as the ratio of double the loop length and the Alfvén speed outside the loop. We extend this study to the leaking regime, considering global sausage modes of long loops with small density contrasts. Methods. Anti-s...

Plasma cell myeloma is a clinically heterogeneous malignancy accounting for approximately one to 2% of newly diagnosed cases of cancer worldwide. Treatment options, in addition to long-established cytotoxic drugs, include autologous stem cell transplant, immune modulators, proteasome inhibitors and monoclonal antibodies, plus further targeted therapies currently in clinical trials. Whilst treat...
