abstract          background and objectives: concentration low-density lipoprotein (ldl) is one of the strongest indicators of atherosclerosis and predicts the diagnosis of cardiovascular diseases. ldl measurement accuracy is very important. ldl can be measured directly, such as enzymatic and nephelometry methods or can be calculated using friedewald's formula. despite the development of e...

introduction: infants born with congenital anomalies demand individualized nutritional evaluations and recommendations. the anatomical changes of neonatal surgical diseases create specific physiological constraints.patients with different congenital anomalies have different nutritional support needs. it is essential to know the exact physiology of these anomalies in order to be able to manage a...

We introduce an atomic formula ~y ⊥~x ~z intuitively saying that the variables ~y are independent from the variables ~z if the variables ~x are kept constant. We contrast this with dependence logic D based on the atomic formula =(~x, ~y), actually equivalent to ~y ⊥~x ~y, saying that the variables ~y are totally determined by the variables ~x. We show that ~y ⊥~x ~z gives rise to a natural logi...

introduction: the parikh’s formula is a calculation method that considers menstrual cycle duration in women who have an unusual interval of menstruation cycle. since the accurate estimation of gestational age affects pregnancy outcomes, the present study aimed to compare the first trimester ultrasound and parikh’s formula in determining the expected date of delivery (edd). materials and methods...

In this study, I introduce some new double sequence spaces [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] as the domain of four-dimensional generalized difference matrix [Formula: see text] in the spaces [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text], respectively. I show that...

Generalizing the formulas of Warnaar and Schlosser, we prove that Schlosser’s qanalogue of the sums of powers has a similar formula, which can be considered as a q-analogue of Faulhaber’s formula. We also show that there is an analogous formula for alternating sums of a q-analogue of powers. MR Subject Classifications: Primary 05A30; Secondary 05A15;

This is an informal introduction to the Kac-Rice formula and some of its (mostly one-dimensional) applications.
