Summary Statements1.The particular follicle-stimulating hormone formulation used for ovarian stimulation does not affect the incidence of hyperstimulation syndrome. (I)2.Coasting may reduce severe (III)3.Coasting longer than 3 days reduces in vitro fertilization pregnancy rates. (II-2)4.The use either luteinizing or human chorionic gonadotropin final oocyte maturation influence (I)5.There is no...

The cascade of events that leads to the development of ovarian hyperstimulation syndrome (OHSS) is almost always accompanied by elevated estradiol (E(2)) levels. The role of estrogen level in OHSS has not been confirmed; however, it was shown repeatedly in the literature that elevated levels of E(2) constitute a risk for OHSS. Monitoring E(2) was found to be effective in reducing the incidence ...

In the CERN PS Booster (PSB), longitudinal Beam Transfer Function (BTF) measurements are used to determine the energy spectrum of the linac beam injected and coasting on an extended flat bottom of the magnet cycle. The short duration (about 10 ms) of the measurement and coherent signals from density structure of the injected beam yielded strongly fluctuating results, and the system fell into di...

Birds, fish and other animals routinely use unsteady effects to save energy by alternating between phases of active propulsion and passive coasting. Here, we construct a minimal model for such behaviour that can be couched as an optimal control problem via an analogy to travelling with a rechargeable battery. An analytical solution of the optimal control problem proves that intermittent locomot...

Instabilities for a coasting proton beam interacting with electron cloud are discussed. The electron sources are roughly classified into two categories reflecting their initial conditions: that is, the electrons produced at the chamber surface and/or at the beam position. If the beam is stable, it forms a Coulomb static potential around itself. Electrons produced near the beam position are trap...
