The article proposes an approach to forecasting mean temperature and total precipitation for the upcoming month, based on study of regularities influence statistical characteristics previous periods them. Among predictors, along with basic characteristics, we use fractality index which is indicator randomness/ determinism climate series. Within framework this approach, have developed models dif...

IN MARCH 1968, approximately 24 million Americans were receiving monthly cash benefits under the old-age, survivors, disability, and health insurance (OASDHI) program. Their monthly benefits were 13 percent or more higher than those paid to beneficiaries through January 1968, with the gains resulting from the across-the-board increase provided by t,he 1967 amendments to the Social Security Act....

In this study, nine-years (1998-2006) of monthly precipitation data from Tropical Rainfall Measuring Mission (TRMM) are used to examine the relations between tropical rainfall and surface temperature. A technique is developed to adjust the PR monthly rainfall data in the Tropics (whole ocean and whole land) to account for the effect of the TRMM orbit boost from 350 km to 402 km in August 2001. ...

This paper reports the study of the effect of the length of the recorded data used for monthly rainfall forecasting. Monthly rainfall data for three periods of 5, 10, and 49 years were collected from Kermanshah, Mashhad, Ahvaz, and Babolsar stations and used for calibration time series models. Then, the accuracy of the forecasting models was investigated by the following year’s data. The follow...

BACKGROUND In June of 2010, an antenatal ultrasound program to perform basic screening for high-risk pregnancies was introduced at a community health care center in rural Uganda. Whether the addition of ultrasound scanning to antenatal visits at the health center would encourage or discourage potential patients was unknown. Our study sought to evaluate trends in the numbers of antenatal visits ...

CONTEXT Ibandronate, a potent, nitrogen-containing bisphosphonate developed for intermittent administration in postmenopausal osteoporosis, aims to overcome current adherence issues with daily and weekly oral bisphosphonates through once-monthly oral dosing. OBJECTIVE The purpose of this study was to investigate the safety, pharmacodynamics, and pharmacokinetics of once-monthly oral ibandrona...

OBJECTIVE The present study aimed at assessing the association between environmental temperature and the relative humidity of the air with frequency of hypertensive disorders of pregnancy. METHODS A prospective and retrospective, descriptive, ecological study was held at a teaching maternity in Recife, Brazil. Data from all 26.125 pregnant women admitted between 2000 and 2006 were analysed an...

Definitions. a) A matrix is called a complex matrix if all its entries are complex numbers. (In particular, any vector in C is considered a n× 1 complex matrix.) b) For any complex matrix A, we denote the matrix A T by A∗. c) Let U2 (C) be the group of all unitary 2× 2 complex matrices. In other words, let U2 (C) = { U ∈ GL2 (C) | U∗ = U−1 } . d) A complex matrix A is called Hermitian if it sat...
