Although survey‐based point predictions have been found to outperform successful forecasting models, corresponding variance forecasts are frequently diagnosed as heavily distorted. Professional forecasters who report inconspicuously low ex ante variances often produce squared forecast errors that much larger on average. In this paper, we document the novel stylized fact misalignment is related ...

background: identifying the predisposing factors of neck and shoulder complaints and finding solutions to avoid them could improve the occupational health condition of the nurses. in this study, we aimed at determining the role of psychological and physical occupational factors in developing neck and shoulder complaints among the participants.   methods: this analytic cross-sectional study was ...

A lattice is called well-rounded if its minimal vectors span the corresponding Eucildean space. In this paper we completely describe well-rounded full-rank sublattices of Z 2 , as well as their determinant and minima sets. We show that the determinant set has positive density, deriving an explicit lower bound for it, while the minima set has density 0. We also produce formulas for the number of...

purpose: to characterize keratic precipitate (kp) morphology in different forms of uveitis. methods: one hundred and twenty nine eyes of 93 patients with different forms of uveitis underwent confocal scan and the morphology of kps were determined. differences in kp morphologies among different uveitic groups were evaluated.  results: age ranged from 14 to 67 years (mean: 32.5±11.2) and 58 cases...

conclusions generalized ligamentous laxity is an important predisposing factor for acute and chronic shoulder injuries in athletes. prescreening programs for beginners and rehabilitation shoulder programs for sports athletes at high risk are strongly recommended. results group a (with ligamentous laxity) consisted of 43 participants (36.4%) and group b (without ligamentous laxity) consisted of ...

Rounded atelectasis of the lung is well described in medical literature, but still difficult to diagnose. Since lesions give no clinical symptoms in patients, radiologists are often the first to recognize the round lesion in an X-ray picture or a CT scan. Rounded atelectasis is an atypical form of lung collapse that usually occurs adjacent to scarred pleura and can be mistaken for lung cancer. ...

BACKGROUND/AIM Fracture toughness determines functional crown strenght and prevents damages on ceramics during mastication. There is a lack of relevant literature data about fracture toughness of crowns made by feather-edge preparation. Mechanical testing of ceramic samples is supposed to show if feather-edge tooth preparation is a successful method for making ceramic crowns without any risk of...
