Relativistic Hermite polynomials and Lorentz beams

The link between relativistic Hermite polynomials and Lorentz beams is shown. That suggests introducing new optical fields. The paraxial propagation properties of such fields are studied in detail. They are finally put in relation to the so-called Weber-Hermite beams, which emerged within a certain class of general solutions of the 1D paraxial wave equation in Cartesian coordinates as a result of a recent re-analysis of such an equation

Economic evaluation of antibiotic prophylaxis in small-cell lung cancer patients receiving chemotherapy: an EORTC double-blind placebo-controlled phase III study (08923).

10-20% for FL per cycle. CONCLUSIONS: Giving oral prophylactic antibiotics to SCLC patients undergoing chemotherapy is the dominant strategy in both GE and NL, demonstrating both cost-savings and superior efficacy. The sensitivity analyses demonstrate that, due to the efficacy of prophylactic antibiotics and their low unit cost, cost savings will incur over a broad range of baseline risks for FL. We recommend the use of prophylactic antibiotics in patients at risk for FL during chemotherapy
