In the evolution processes of wind blown sand movement and aeolian geomorphology, it always contains some complex behaviors, for example, the nonlinear character of turbulence and attractors, the stochastic character of wind gust, liftoff and movement of sand, the interaction among wind field, sand movement, electric field in wind blown sand flux and thermal diffusion, multi-scale character fro...

Straw checkerboard barrier (SCB) is the most representative antidesertification measure and plays a significant role in antidesertification projects. Large-eddy simulation and discrete-particle tracing were used to numerically simulate the wind sand movement inside the straw checkerboard barrier (SCB), study the movement characteristics of sand particles, find the transverse velocities of sand ...

On June 2, 2015, Irwin (Ernie) Rose died quietly in his sleep at age 88, after a long and fruitful lifetime of sleuthing for the secrets of life at the molecular level. Truly great scientists are much more than the sum of their publications and awards. This is especially true for Ernie who, when informed that he had been awarded the 2004 Nobel Prize in Chemistry, wondered aloud whether he reall...

Hierarchical structure is ubiquitous in data across many domains. There are many hierarchical clustering methods, frequently used by domain experts, which strive to discover this structure. However, most of these methods limit discoverable hierarchies to those with binary branching structure. This limitation, while computationally convenient, is often undesirable. In this paper we explore a Bay...

This paper is an introduction to rose links and some of their properties. We used a series of invariants to distinguish some rose links that are rotationally symmetric. We were able to distinguish all 3-component rose links and narrow the bounds on possible distinct 4 and 5-component rose links to between 2 and 8, and 2 and 16, respectively. An algorithm for drawing rose links and a table of ro...

The genus Rosa Linn. (Rosaceae) is widely distributed in the temperate parts of the northern hemisphere and on tropical mountains. About 20 species and hundreds of varieties have been recorded in India in wild state and many have been introduced for cultivation as ornamentals. Mostly hybrid varieties exhibit a marked fragrance and are suitable for the extraction of Rose water and Rose oil (atta...

Depression is one of the most common psychiatric disorders that may result in significant consequences in active population of the society. In traditional manuscripts there are many indications about the antidepressant effects of rose oil, but so far no scientific research has been done about this subject. The purpose of present study was to determine the antidepressant effects of rose oil and ...
