OBJECTIVE To present a new gestational-age-specific percentile curve for symphysis-fundus (SF) height and to determine the effects of maternal and fetal covariates. DESIGN A population-based register study. SETTING Antenatal clinics in Västra Götaland County, Sweden, between 2005 and 2010. POPULATION A total of 42 018 women with ultrasound-dated singleton pregnancies who delivered at Sahl...

A construction is given for a stationary sequence of random variables {X.} which have exponential marginal distributions and are random linear combinations of order one of an i.i.d. exponential sequence {e.}. The Joint and trivariate exponential distributions of X.,, X. and X... are studied, as well as the Intensity function, point spectrum and variance time curve for the point process which ha...

among different models for runoff estimation in watershed management, the soil conservation services-curve number (scs-cn) method along with its modifications have been widely applied to ungauged watersheds because of quickly and more accurate estimation of surface runoff. this approach has been widely accepted by hydrologists, water resources planners, foresters, and engineers, as well. theref...

The explanation of the multi-exponential washout of inert gas tracers from skeletal muscle is a source of controversy. The two most likely explanations are a heterogeneous flow pattern and countercurrent shunting of gas. Autoradiographs of canine skeletal muscle obtained after injection of *‘Kr indicate that heterogeneous flow is present in this preparation which would cause multi-exponential c...

hence it yields an isomorphism between the quotient additive group C/2πiZ and the multiplicative group C×. The group C× is the group of complex points of the multiplicative group Gm; z 7→ e is the exponential function of the multiplicative group Gm. We shall replace this algebraic group by an elliptic curve. We could replace it also by other commutative algebraic groups. As a first example, the...

SUMMARY An upper bound is established for certain exponential sums on the rational points of an elliptic curve over a residue class ring Z N , N = pq for two distinct odd primes p and q. The result is a generalization of an estimate of exponential sums on rational point groups of elliptic curves over finite fields. The bound is applied to showing the pseudoran-domness of a large family of binar...

In this paper, we are interested in giving bounds for exponential sums over certain curves defined over Galois rings. We first define summation subsets as the images of lifts of affine pieces of the reduced curve, and most of the work is devoted to giving bounds for the degrees of their defining functions. Then we get bounds for exponential sums, generalizing results of Kumar et al., Winnie Li ...

Exponential relaxation to equilibrium is a typical property of physical systems, but inhomogeneities are known to distort the exponential relaxation curve, leading to a wide variety of relaxation patterns. Power law relaxation is related to fractional derivatives in the time variable. More general relaxation patterns are considered here, and the corresponding semi-Markov processes are studied. ...

To determine the mechanical factors affecting regional segmental motion after acute coronary occlusion, we studied seven conscious dogs, instrumented with sonomicrometers. Loading conditions were changed by the withdrawal of 500 ml of blood and the transfusion of 800 ml of blood. To express segmental motion, percent systolic shortening, percent systolic elongation, and early diastolic shortenin...

The exponential behaviour of the voltage-to-current characteristic is of primary importance because it enables us to construct a current source, which delivers a current that is proportional to the absolute temperature (PTAT). This can be used to implement a mechanism of temperature compensation in a bandgap reference circuit [8]. The conventional diode has an exponential voltage-to-current rel...
