Flexibility-rigidity index (FRI) has been developed as a robust, accurate, and efficient method for macromolecular thermal fluctuation analysis and B-factor prediction. The performance of FRI depends on its formulations of rigidity index and flexibility index. In this work, we introduce alternative rigidity and flexibility formulations. The structure of the classic Gaussian surface is utilized ...

Body: Objective: Clarify insulin resistance (IR), diabetes mellitus (DM) and low cerebral flow reserve contributions to stroke (S) and dementia (D). Methods: Among 300 patients with cerebral ischemia symptoms, brain SPECT indices of basal metabolism (CMi), stimulated perfusion (CPi) and cerebral flow reserve (FRi = CPi – CMi and FRr = net stimulated/basal counts) used parabolic renal correction...

Oyster beds in Galveston Bay, Texas, were closed to harvesting during most of the summer of 1998 because 416 persons in 13 states fell ill after eating raw oysters traced to this location (21). Then, just as these shellfish beds appeared to be safe again, New York authorities forbade the harvest of clams and oysters from beds near Long Island in mid-September, after 10 people became ill from ea...

Data mining is a widely used technology for various real-life applications of data analytics and important to discover valuable association rules in transaction databases. Interesting itemset plays an role many applications, such as market, e-commerce, finance, medical treatment. To date, algorithms based on frequent patterns have been studied, but there are few that focus infrequent or rare pa...

To complete the sparse sampling of linear frequency modulation (LFM) signals and estimate parameters, authors proposed an improved finite rate innovation (FRI) system to achieve goal. First build a mathematical model based on Z-transform, then they input LFM signal into modified FRI process output this model, which enables estimation parameters using only four points. The error final experiment...

In wind-pollinated plants, male-biased sex allocation is often positively associated with plant size and height. However, effects of size (biomass or reproductive investment) and height were not separated in most previous studies. Here, using experimental populations of monoecious plants, Ambrosia altemisiifolia, we examined (1) how male and female reproductive investments (MRI and FRI) change ...

A differential pattern in the RAPD profile of Eucalyptus F1 natural hybrids FRI-4 (E. terticornis x E. camaldulensis), FRI-5 (E. camaldulensis X E. tereticornis) and controlled reciprocal crosses FRI-14 (E. torelliana X E. citriodora) along with their parental combinations was assessed through Polymerase Chain Reaction using commercially available primers. After electrophoresis of PCR product t...
