The motion of an ion in a radiofrequency (rf) Paul trap is described by the Mathieu equation and associated stability parameters that are proportional to rf dc electric field gradients. Here, higher-order, iterative method accurately solve from measured secular frequencies presented. It then used characterize endcap showing trap's radial asymmetry dominated gradients measuring relation between ...

High-accuracy protein structure modeling demands on accurate and very fast side chain prediction since such a procedure must be repeatedly called at each step of structure refinement. Many known side chain prediction programs, such as SCWRL and TreePack, depend on the philosophy that global information and pairwise energy function must be used to achieve high accuracy. These programs are too sl...

We predict accuracy of user’s preferences by using memory-based collaborative filtering algorithm in recommender system, and then analyze the results through the EDA approach. The possibilities are presented that prediction accuracy can be evaluated before prediction process by analyzing the results. The classification functions using the generative probability of specific ratings are made, and...

background: increased serum high sensitive c-reactive protein (hs-crp) in asthma and its association with disease severity has been investigated in many studies. this study aimed to determine serum hs-crp status in asthma versus healthy controls and to examine its ability in predicting asthma control. methods: serum crp was measured by elisa method using a high sensitive crp kit. severity of as...

A new approach based on a Generalized Regression Neural Network (GRNN) has been proposed to predict the planform surface pressure field on a wing-tail combination in low subsonic flow. Extensive wind tunnel results were used for training the network and verification of the values predicted by this approach. GRNN has been trained by the aforementioned experimental data and subsequently was used ...
