Checksums are routinely used to detect data transmission errors. However, design decisions about which checksum to use are difficult because of a lack of information about relative effectiveness of available options. We study the error detection effectiveness of the Fletcher and Adler checksums for random independent bit errors and burst errors. Our study reveals that in most cases the Fletcher...

A simple unitarized quark-meson model, recently applied with success to light and charmed scalar mesons, is shown to encompass Adler-type zeros in the amplitude, due to the use of relativistic kinematics in the scattering sector. These zeros turn out to be crucial for the description of the K∗ 0 (800) resonance, as well as the new charmed scalar mesons D∗ s0(2317) and D ∗ 0(2300). The light sca...

patients and materials the method used in this research was correlational and statistical population was the students of the university of qom in 2013. 118 students responded to islamic lifestyle and purpose in life questionnaires. the data had been analyzed with the use of descriptive indicators, t-test, pearson and regression. results based on the results of the study, there is a direct and m...

We study the QCD Adler function in energy region $\approx 0.7-2.5$ GeV, which non-perturbative effects become dominant. Our analysis is a renormalon-based evaluation using transseries within resurgence of Renormalization-Group-Equation and does not require Operator-Product-Expansion.
