Abstract   Background: A significant relationship between psychiatric disorders principally   depression and anxiety and insomnia is well-known in general population. Ahigh percent   of insomnia sufferers report anxiety symptoms. Anxiety is also frequently seen in   medical patients whom complaints of sleep problems are often prominent.   Method: 250 outpatients with various medical complaint...

Büyüyen ülkelerin karşı karşıya olduğu en önemli sorunlardan biri, ekonomik kalkınmayı finanse edecek yeterli rezervlere sahip olmamalarıdır. Bu durum dış borç ihtiyaçlarını artıran sebeplerden biridir. Ayrıca döviz kurundaki geçişkenlik, gelişmişlik düzeyine göre makroekonomik göstergeleri olumlu veya olumsuz yönde etkilemektedir. Türkiye, kırılgan yapısı ve çözülmesi gereken sorunları nedeniy...

OBJECTIVE To compare the success and ease of bougie-assisted intubation (BAI) with those of traditional endotracheal intubation (ETI) in a simulated difficult airway (20.4 seconds for BAI vs. 16.7 seconds for ETI, p = 0.102). METHODS This was a prospective, randomized, crossover, single-blind study comparing BAI with ETI in a simulated difficult airway. The 35 participants included paramedics...

OBJECTIVE A recent, cross-sectional analysis of adults found that the hip circumference divided by height(1.5) minus 18 (the body adiposity index, BAI) was strongly correlated (r = 0.79) with percent body fat determined by dual energy X-ray absorptiometry. The BAI was proposed as a more accurate index of body fatness than BMI. We examined whether BAI was more strongly related, than was BMI and ...

In this paper a new quantity for real tensors, the sign-real spectral radius, is defined and investigated. Various characterizations, bounds and some properties are derived. In certain aspects our quantity shows similar behavior to the spectral radius of a nonnegative tensor. In fact, we generalize the Perron Frobenius theorem for nonnegative tensors to the class of real tensors.

Keywords: Additive/multiplicative splitting iteration method Singular linear systems Hermitian matrix Semiconvergence a b s t r a c t In this paper, we investigate the additive, multiplicative and general splitting iteration methods for solving singular linear systems. When the coefficient matrix is Hermitian, the semiconvergence conditions are proposed, which generalize some results of Bai [Z....

Phillips curves are generally estimated under the assumption of linearity and parameter constancy. Linear models of inflation, however, have recently been criticized for their poor forecasting performance. The author investigates the linearity and constancy assumptions of a standard reduced-form Phillips curve for Canada using two different techniques: (i) the methodology proposed by Bai and Pe...

A new technique for estimating countries’ de facto exchange rate regimes synthesizes two approaches. One approach estimates the implicit de facto basket weights in an ordinary least squares (OLS) regression of the local currency value rate against major currency values. Here the hypothesis is a basket peg with little flexibility. The second estimates the de facto degree of exchange rate flexibi...

Salmonellosis, campylobacteriosis and listeriosis are food-borne diseases. We estimated and forecasted the number of cases of these three diseases in Belgium from 2012 to 2020, and calculated the corresponding number of disability-adjusted life years (DALYs). The salmonellosis time series was fitted with a Bai and Perron two-breakpoint model, while a dynamic linear model was used for campylobac...
