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 ...

The leaf epidermis was studied in individuals of different ages (juvenile plants 1st year, immature year and 2nd years life) Ferula tadshikorum the family Apiaceae, grown conditions Tashkent Botanical Garden. leaves are amphistomatic ages. Plants characterized by presence three types stomata: anomocytic, hemiparacytic paracytic, which simultaneously present on both surfaces. anomocytic type sto...

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...

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. ...
