background: the ability of the ovary to respond to exogenous gonadotrophin stimulation and development of several follicles is essential in assisted reproductive technology. neither age and regularity of menses nor follicular phase fsh and estradiol concentrations are reliable predictors of ovarian response. day 3 serum inhibin-b level, during induction ovulation, has been proposed as a predict...

Background Reduced ovarian reserve has been known to predict poor ovarian response and poor success rates in infertile women undergoing assisted reproductive technology. Ovarian reserve also decreases with age but the rate of decline defers from a woman to another. The aim of this study was to detect any difference in ovarian reserve as measured by basal serum FSH and AMH between matched cohort...

Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceive...

Recent progress suggests that integrative cardiac reserve is important in coronary artery disease, chronic heart failure, cardiomyopathy, and other cardiovascular diseases. Integrative cardiac reserve includes coronary flow reserve, myocardial reserve, energy reserve, and heart rate reserve. In the case of stress reaction, coronary flow reserve can provide excessive blood and energy supply and ...

Description The IMO may use ‘out-of-market’ sources of reserve in response to an operating reserve shortfall in the real-time constrained sequence.1 Operating reserve shortfalls occur when either the total amount of available MW offered in the market for a class of operating reserve is less than the IMO’s requirement for that class of reserve, or when the total amount of available MW offered fo...

Security-constrained unit commitment (SCUC) is a classical problem used for day-ahead commitment, dispatch, and reserve scheduling. Even though SCUC models acquire reserves, N-1 reliability is not guaranteed. This paper presents an enhanced securityconstrained unit commitment formulation that facilitates the integration of stochastic resources and accounts for reserve deliverability issues. In ...

We investigate equilibrium bidding in first-price auctions with asymmetric reserve prices. For example, the auctioneer may set a low reserve price for one subset of bidders and a high reserve price for others. When used to pursue a distributional objective, lowering the reserve price for some bidders channels benefits toward marginal agents in the favored group and does not adversely impact non...

myocardial fractional flow reserve (ffr) is a new index of the functional significance of intermediate coronary stenoses that is calculated from pressure measurements made during coronary arteriography. the aim of this study was to evaluate the correlation between non-hyperemic coronary pressure dicrotic notch and fractional flow reserve (ffr). a consecutive of 114 patients (73 men and 41 women...

OBJECTIVE White matter hyperintensities (WMH), visualized on T2-weighted MRI, are thought to reflect small-vessel vascular disease. Much like other markers of brain disease, the association between WMH and cognition is imperfect. The concept of reserve may account for this imperfect relationship. The purpose of this study was to test the reserve hypothesis in the association between WMH severit...
