A muonium hydride molecule is a bound state of and hydrogen atoms. It has half the mass parahydrogen very similar electronic properties in its ground state. The phase diagram an assembly such particles investigated by first-principles quantum simulations. In bulk limit, low-temperature equilibrium crystal extraordinarily low density, lower than that any other known atomic or molecular crystal. ...

A watermarking scheme is presented to embed watermarks into wavelet DC components. The DC area is not suitable for embedding watermark because of severe visual degradation. To overcome degradation problem, we embed watermark into visually insensitive locations. To detect visually insensitive locations, we perform medianfiltering to the lowest frequency sub-band of wavelet transform. The robustn...

There are two main method of presenting data: a) Tabulation A most common way of presenting data in the tables is known as frequency distribution table. Frequency is the no. of units belonging to group of the variable. The variable characteristics such as age has a range from lowest to highest, the age for example ranges between 4---------12. This range is divided into subgroups called classes ...

Background: Gastrointestinal Cancers are one of the most important causes of mortality of patients in the world as well as in our country. The North of Iran is in Asian belt of esophagus cancer in addition, in other areas of our country gastric cancer is the most common GI Cancer. Because GI Cancers are common in Lorestan, we decided to study them in patients undergo endoscopy and colonoscopy i...

The behavioral audiograms of slow loris and potto were determined by the technique of conditioned suppression, and the auditory characteristics of Prosimians then estimated by combining the data with that of bushbaby. It is concluded that high-frequency hearing, low-frequency sensitivity, and total area of the audible field are well correlated with phyletic level, while lowest threshold and bes...

Associations between alcohol drinking and cardiovascular disease mortality could be confounded by diet if alcohol drinking and diet are related. Depending on the alcohol measure, alcohol-diet relations may or may not be observed. The authors examined associations between alcohol and diet quality (Healthy Eating Index (HEI) scores) using cross-sectional, nationally representative data from the 1...

We investigate the effects mode truncation and dissipation characteristics have on predictions of wave shape statistics such as skewness and asymmetry. We demonstrate the effect of mode truncation by calculating wave shape statistics for data from a laboratory experiment using an increasing number of frequency components each calculation. We find that the values of skewness and asymmetry conver...

A methodology for tuning the stiffness of machine tool supports is described based on a stiffness model using the contact stiffness approach. Using this model, the mathematical relationship between the load of the support and its stiffness is established. The relationship is separated into three regions. When the total stiffness of all supports is maximized, the load must be tuned so that the s...
