[1] In order to validate the reported precision of space‐based atmospheric composition measurements, validation studies often focus on measurements in the tropical stratosphere, where natural variability is weak. The scatter in tropical measurements can then be used as an upper limit on single‐profile measurement precision. Here we introduce a method of quantifying the scatter of tropical measu...

background: there is a worldwide interest in searching for potential and effective medicinal plant candidates against various diseases or disorders. till now, there are number of anti-inflammatory drugs like nsaids are available which showed various adverse effects in our body. to reduce these adverse effects, some of medicinal plants have been experimentally validated. aim: the aim of our immu...

An investigation was performed of the changes in image quality and patient dose as a result of increasing filtration for fluoroscopy performed under automatic brightness control. Filtration was added either at the x-ray tube housing (i.e., scatter-free geometry) or adjacent to a tissue equivalent phantom simulating the patient (i.e., with-scatter geometry). Patient doses were expressed in terms...

The scatter-hoarding behavior of granivorous rodents plays an important role in seed dispersal and seedling regeneration of trees, as well as the evolution of several well-known mutualisms between trees and rodents in forest ecosystems. Because it is difficult to identify seed hoarders and pilferers under field conditions by traditional methods, the full costs incurred and benefits accrued by s...

Many animals use cues for small-scale navigation, including beacons, landmarks, compasses and geometric properties. Scatter-hoarding animals are a unique system to study small-scale navigation. They have to remember and relocate many individual spatial locations, be fairly accurate in their searching and have to remember these locations for long stretches of time. In this article, we review wha...

It has long been speculated that cognitive subtest scatter or variability is a pathognomonic sign. Early researchers hypothesized that subtest scatter would predict scholastic potential or membership in exceptional groups (Harris & Shakow, 1937). In fact, Binet suggested that scattered passes and failures on the Binet-Simon scale were diagnostically significant (Matarazzo, 1985), and Wechsler (...

Scatter correction is an important factor in single photon emission computed tomography (SPECT). Many scatter correction techniques, such as multiple-window subtraction and intrinsic modeling with iterative algorithms, have been under study for many years. Previously, we developed an efficient slice-to-slice blurring technique to model attenuation and system geometric response in a projectorhac...
