BACKGROUND We aimed to compare human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (r FSH) with respect to clinical outcomes and the development of ovarian hyperstimulation syndrome (OHSS) for patients with polycystic ovary syndrome (PCOS) treated with in vitro fertilization (IVF). MATERIALS AND METHODS This prospective randomized controlled trial included a total...

The energy-efficient train control can effectively reduce energy consumption of railway network by optimizing driving strategy. This paper proposed a method for strategy two-stage allocation redundant running time. time-optimal requires shortest time while highest consumption. By time, be transferred to energy-optimal under the premise that arrives on In first stage, part is allocated long coas...

This study reports 21 IVF cases with excessive ovarian response, who received gonadotrophin-releasing hormone agonist (GnRHa) triggering for final oocyte maturation, followed by a human chorionic gonadotrophin (HCG)-based, progesterone-free, luteal support, individually timed ('luteal coasting') according to endogenous luteal progesterone concentrations. One patient developed a brief early-onse...

The aim of this review was to summarize previously published classifications for ovarian hyperstimulation syndrome (OHSS), as well as to analyse the available methods for preventing OHSS. Withholding hCG and cycle cancellation--once the main methods of preventing OHSS--are now seldom used. There is a growing body of evidence to support the use of coasting to prevent OHSS, without cycle cancella...

For the upgrade of the SIS-18 synchrotron it is of importance that the initial momentum spread of the injected coasting beam does not exceed the limit set by the rf bucket area. The lower limit is determined by microwave instabilities which cause a sudden increase of the momentum spread below a threshold momentum spread. For a coasting Ar beam in the SIS-18 the measured momentum spread as a fun...

BACKGROUND Withholding gonadotrophins (coasting) can reduce the risk of severe ovarian hyperstimulation syndrome (OHSS) in patients having assisted reproduction therapy. This requires daily serum estradiol (E(2)) measurements, which occasionally have been seen to decline suddenly and sharply. METHODS To increase the sensitivity of the coasting programme we measured serum FSH in parallel with ...

One method accomplishing this regenerative braking, which converts kinetic to electrical stored in pack while vehicle decelerating. Coasting an alternative strategy that minimizes by decelerating ...

Reputation concerns can discipline agents to take costly effort and generate good outcomes. But what if outcomes are not always observed? We consider a model of reputation with shifting observability, and ask how this affects agents’ incentives. We identify a novel and intuitive mechanism by which infrequent observation or inattention can actually strengthen reputation incentives and encourage ...
